The present invention relates to an air-filling packaging apparatus, and more particularly to an air-filling packaging apparatus that has a cushioning function.

With the change of modern lifestyles and the rapid development of logistics industry, numerous goods, such as electronic products, chemical products, medical products, ceramics, glass, and other daily necessities, are traded through logistics. Nevertheless, serious loss can happen when these goods are damaged or distorted due to incidents like squeezing, collision, dropping, etc., which are sometimes inevitable during the storing or transportation processes.

In order to protect the goods, people utilize packaging box or the like to package the products before storing or transportation, which provides a certain cushioning function for the products so as to protect them. Currently, common packaging to boxes include paper packaging boxes and air packaging bags. A Conventional paper packaging box cannot offer an ideal cushioning function to serve as a good protection. As a result, it usually requires the products being packaged by foams or soft plastics for several layers before putting into the packaging box in order to provide a good anti-collision quality. Unfortunately, this will definitely increase its transportation cost, make packaging process harder, waste time, decrease working efficiency, and raise labor cost, which has failed to meet the demands of modern transportation industry.

On the other hand, air packaging substances provide the cushioning function by filling air into films, which can be inflated and utilized right on the packaging site. Therefore, contrasting to conventional packaging solutions, air packaging materials have the advantages of lower transportation cost, easier storing, better cushioning performance, and more environmental friendly. Conventional air packaging bags usually include a plurality of air side walls formed of bent air-storing columns. The air side walls surround to form an internal accommodation for storing an object. A few common examples thereof include a U-shaped bag, a C-shaped bag, an O-shaped bag, and etc. Unfortunately, the single cushion structure of such conventional packaging bags or the arrangement of the air cushion fits on and around the object still cannot provide a satisfied cushioning function in some situations that require a relatively higher anti-collision performance.

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

FIG. 1-6 illustrate the air-filling packaging apparatus according to a first preferred embodiment of the present invention, which has an inflatable structure so as to be inflated to provide an air cushioning function for various packaged objects, such as electronic products, food, medical products, chemical products, biological materials, plastics and ceramics, and fast moving consumer goods. The air-filling packaging apparatus can be easily stored and transported in a non-inflated state before use, while it can then be inflated on site, which is convenient to use.

According to this preferred embodiment of the present invention, the air-filling packaging apparatus can be embodied as an air cushion material which is filled with air for example. Nevertheless, person skilled in the art should be able to understand that it can also be filled with other gas based on the application and needs. According to this preferred embodiment, it can form a 3D packaging bag after being inflated, so as to provide air cushioning function for an object.

According to the this preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 . Namely, either one of the air cushion body 10 forms a 3D packaging bag or a plurality of the air cushion bodies 10 form the 3D packaging bag through heat-sealing connecting, such as adhesive bonding, heat-sealing, and etc. The embodiment illustrated in FIGS. 1-6 is formed by one air cushion body 10 . More specifically, referring to FIG. 71A , the air cushion body 10 comprises at least two air chamber films 11 and 12 forming the 3D packaging bag comprising one or more interconnected air-storing units 13 through a series of 2D heat-sealing seams 30 and 3D heat-sealing seams 40 , wherein each the air-storing unit 13 forms a air storage chamber 14 that is able to store gas therein.

Person skilled in the art should be able to understand that the 2D heat-sealing seams 30 are for sealing multiple films into a 2D cushion material, as is illustrated in FIG. 5 , through heat-sealing. The 3D heat-sealing seams 40 are additional heat-sealing on the above 2D cushion material to turn the air-filling packaging apparatus into a 3D packaging device that has a 3D structure and can accommodate the object, as FIG. 1 illustrates. The 2D heat-sealing seams 30 and the 3D heat-sealing seams 40 can connect multiple layers of films together through adhesive bonding, heat-sealingly connection, and etc. Preferably, according to this embodiment, the 2D heat-sealing seams 30 and the 3D heat-sealing seams 40 are both formed through heat-sealing technology.

More specifically, the 2D heat-sealing seams 30 comprise a plurality of dividing seams 31 dividing the two air chamber films 11 and 12 into a plurality of the air-storing units 13 . Preferably, each row of the dividing seams 31 is formed by heat-sealing technology that heat-sealingly connects two layers of the air chamber films 11 and 12 so as to form a row of the dividing seam 31 between two adjacent air-storing units 13 . Each of the dividing seams 31 may be a continuous heat-sealed line so as to allow a plurality of the air-storing units 13 to be independent to one another. It is understandable that the dividing seam 31 on the top side and the bottom side can respectively become a top side boundary seam and a bottom side boundary seam of the air cushion body 10 , as FIG. 5 illustrates. The dividing seam 31 may also be an intermittent heat-sealed line so as to have a plurality of the air-storing units 13 be interconnected. The air-storing unit 13 can be in various shapes, such as linear, circular, polygon, irregular, and etc. Referring to FIGS. 1-6 , the air cushion body 10 according to the present invention may comprise a plurality of air-storing pillars abreast arranged, but the present invention shall not be limited thereto.

According to this preferred embodiment, referring to FIG. 71A , the air cushion body 10 further comprises an inflation valve 20 formed by at least two valve films 21 and 22 . The two valve films 21 and 22 of the inflation valve 20 and the air chamber films 11 and 12 are overlappedly arranged. Besides, an air inlet channel 23 is formed between the valve films 21 and 22 for inflating air into the air storage chamber 14 . It is understandable that the lengths of the valve films 21 and 22 are shorter than the lengths of the air chamber films 11 and 12 . When the air storage chamber 14 is inflated via the air inlet channel 23 and the air pressure in the air storage chamber 14 has attained the predetermined required value, the air pressure in the air storage chamber 14 will act on the valve films 21 and 22 so as to attach the valve films 21 and 22 on one of the air chamber film, which closes the air inlet channel 23 and makes the inflation valve 20 serve as a one-way valve. When each air-storing unit 13 has at least an air inlet channel 23 formed therein and each of the air-storing units 13 is independent to one another, even if one of the air-storing units 13 is damaged and leaks, the rest of the air-storing units 13 will not be affected, but still serve to provide air cushions.

It is understandable that the air chamber films 11 and 12 of the air cushion body 10 and the valve films 21 and 22 of the inflation valve 20 can respectively be made of various suitable membrane materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, composite film, and etc, wherein the present invention shall not be limited thereto, as long as suitable flexible films are utilized. It is worth mentioning that in order to enhance the one-way sealing function, the valve films 21 and 22 of the inflation valve 20 can also be self-adhesive films acquired by adding chemical composition to the above films.

The air cushion body 10 further comprises a main channel unit 15 connected with each of the air-storing units 13 preferably, integrally extended from each of the air-storing units 13 . More specifically, according to this preferred embodiment, the extending directions of the main channel unit 15 and the air-storing unit 13 are perpendicular to each other. For example, according to this embodiment, each the air-storing unit 13 is extended along a transverse direction, while the main channel unit 15 is extended along a longitudinal direction. The main channel unit 15 forms a main channel 151 that has an inflation inlet 152 . When the inflation inlet 152 has an inflation nozzle arranged thereat for conducting an inflation process, gas will enter the main channel 151 from the inflation inlet 152 along a longitudinal direction, and enter each the air-storing unit 13 along a transverse direction. Then, when the air pressure of each the air storage chamber 14 reaches a predetermined value, the valve films 21 and 22 of the inflation valve 20 will attached on one of the air chamber films 11 and 12 , so as to self-seal and prevent the inflated gas from reversing into the main channel 151 .

It is worth mentioning that, it is understandable that the main channel unit 15 can be formed by two layers of the air chamber films 11 and 12 , two layers of the valve films 21 and 22 , or either one layer of the air chamber films 11 and 12 and either one layer of the valve films 21 and 22 .

Referring to FIG. 5 , the 2D heat-sealing seams 30 further comprise a continuously sealed edge sealing seam 32 respectively on the left and right sides and a continuously sealed main channel sealing seam 33 on the left side of the air cushion body 10 , wherein the main channel 151 is formed between the left edge sealing seam 32 and the main channel sealing seam 33 . It is understandable that the edge sealing seam 32 is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealedly connect the two air chamber films 11 and 12 . The main channel sealing seam 33 is formed through heat-sealing technology, such as adhesive bonding and heat-sealing, to sealedly connect the two air chamber films 11 and 12 and the two valve films 21 and 22 respectively, as FIG. 71A illustrates. For example, the main channel sealing seam 33 on the up and down sides that are formed through a first heat-sealing technology respectively heat-sealedly connects the air chamber film 11 and the valve film 21 and heat-sealedly connects the air chamber film 12 and the valve film 22 .

Referring to FIG. 5 , each air-storing unit 13 comprises two spaced gas duct seams 34 adjacent to the main channel 151 and formed through heat-sealedly connecting the air chamber films 11 and 12 and the valve films 21 and 22 . The air inlet channel 23 formed by the valve films 21 and 22 are arranged between the two gas duct seams 34 .

Referring to FIG. 71A , the valve films 21 and 22 are further heat-sealedly connected with the air chamber film 11 through a plurality of connecting seams 35 , such that when the air pressure in the air storage chamber 14 attained a predetermined value, the air pressure will act on the valve films 21 and 22 and because of the arrangement of the connecting seams 35 , the valve films will be pushed toward the air chamber film 11 and eventually be attached on the air chamber film 11 , so as to close the air inlet channel 23 . That is to say, the connecting seams 35 heat-sealedly connect the two valve films 21 and 22 and the air chamber film 11 . Besides, referring to FIG. 5 , the shape of each the connecting seams 35 allows it to further prevent the air from backflow. In other words, when the air in the air storage chamber 14 is going to flow back, it will be obstructed by the connecting seams 35 and cannot return into the main channel 151 easily.

In addition, when the 2D heat-sealing seams 30 are being formed through heat-sealing, the air inlet channel 23 of the valve films 21 and 22 of the inflation valve 20 can be formed through the arrangement a heatproof barrier device. Then the heatproof barrier device can be removed after the heat-sealing process. According to this embodiment, referring to FIGS. 5 and 71A , a heatproof layer 24 is arranged between the valve films 21 and 22 of the inflation valve 20 and attached with the inner surface of one of the valve films 21 and 22 . The heatproof layer 24 can be embodied as thermostable inks and etc. As a result, when the main channel sealing seam 33 is formed through heat-sealing, the two valve films 21 and 22 will not be heat-sealedly connected, such that the air inlet channel 23 can be connected with the main channel 151 and the access thereof will not be closed due to the heat-sealing.

According to this preferred embodiment, the main channel 151 is formed by the two air chamber films 11 and 12 , the heatproof layer 24 and the valve films 21 and 22 respectively have extending section extended into the main channel 151 , and the 2D heat-sealing seams 30 further comprise a joint seam 36 longitudinally and spacingly arranged at the position corresponding to the extending section of the heatproof layer 24 . Because of the arrangement of the heatproof layer 24 , the joint seam 36 respectively connects the two air chamber films 11 and 12 and the two valve films 21 and 22 , while the two valve films 21 and 22 are not heat-sealedly connected with each other. The arrangement of the joint seam 36 allows adjacent valve films 21 and 22 and the correspondingly connected air chamber films 11 and 12 to be expanded together to open the corresponding air inlet channel 23 when air enters the main channel 151 during the inflation of the air cushion body 10 .

The 2D heat-sealing seams 30 further comprises a plurality intermittent bending seams 37 , wherein the inflated air cushion body 10 is adaptable for bending along the bending seams 37 , such that the air cushion body 10 can form a plurality of side walls. More specifically, the bending seams 37 divides each the air-storing unit 13 into a plurality of sub-air-storing units 131 . The bending seams can be arranged in the middle of the air-storing units 13 and respectively form a connecting channel 132 on the two sides thereof, such that the adjacent sub-air-storing units 131 can be interconnected and communicated, as FIG. 5 illustrates. It is understandable that the bending seam can also be arranged on the two sides of the air-storing units 13 , while the connecting channel 132 is arranged in the middle of the air-storing units 13 . Correspondingly, it is understandable that each bending seam 37 heat-sealedly connects two layers of the air chamber films 11 and 12 .

Referring to FIG. 5 , the 2D heat-sealing seams 30 further comprises a choke seam 38 sealing off the air inlet channel of the two air-storing units 13 , as the figure illustrates, of the air-storing units 13 on the top side of the air cushion body 10 . Namely, the choke seam can be arranged near by the tail of the air inlet channel 23 to heat-sealedly connect the two air chamber films 11 and 12 and the two valve films 21 and 22 , so as to make each the air-storing unit 13 uninflatable and form non-inflated air-storing pillar.

Correspondingly, the arrangement of the choke seam 38 can divide a plurality of transversely extended air-storing units 13 into a plurality of inflatable air-storing units 13 a and a plurality of uninflatable air-storing units 13 b arranged longitudinally. For instance, referring to FIG. 5 , the three air-storing units on the top side are uninflatable, which are, according to this embodiment of the present invention, to form an inner bag portion 10 b , while the four inflation units 13 a on the bottom side are inflatable, so as to form an outer bag portion 10 a . In other words, according to this preferred embodiment of the present invention, it provides cushioning function in a multistage manner through the inflatable outer bag portion 10 a and the non-inflated inner bag portion 10 b.

Further, according to the embodiment illustrated in FIGS. 1-5 , the 2D heat-sealing seams 30 comprise four rows of the bending seams 37 , such that the air cushion body 10 is adaptable to form the right front side wall 101 , right side wall 102 , rear side wall 103 , left side wall 104 , and left front side wall 105 along the four bending seams 37 . The above mentioned side walls 101 - 105 are bent to form a cavity 106 with an opening 107 on the top side thereof. Namely, the side walls 101 - 105 are surroundingly arranged and the air-storing units 13 respectively to form a ringlike air-storing pillar. That is, referring to FIG. 5 , the left part of the first row of the bending seam 37 is arranged for forming the right front side wall 101 , the right side wall 102 is formed between the first and second rows of the bending seams 37 , the rear side wall 103 is formed between the second and third rows of the bending seams 37 , the left side wall 104 is formed between the third and fourth rows of the bending seams 37 , and the left front side wall 105 is formed in the right side of the fourth row of the bending seam 37 . It is understandable that the side walls 101 - 105 are respectively formed by the sub-air-storing units 131 integrally extended from the air-storing unit 13 along the length direction thereof.

Correspondingly, referring to FIGS. 1 and 5 , the 3D heat-sealing seams 40 comprise a transverse heat-sealing seam 41 on the bottom side heat-sealing and connecting the bottom sides the front side wall 101 and the rear side wall 103 , so as to seal off the bottom side of the outer bag portion 10 a . The 3D heat-sealing seams 40 further comprise a transverse heat-sealing seam 42 on the top side heat-sealing and connecting the top sides of the front side walls 101 and 105 and the rear side wall 103 , so as to seal off the top side of the inner bag portion 10 b . The 3D heat-sealing seams 40 further comprise a longitudinal end sealing seam 43 heat-sealedly connecting the right front side wall 101 and the left front side wall 105 along the longitudinal direction which means the air cushion body 10 is circularly arranged and the head and tail thereof are connected. Thus, the air cushion body 10 is able to form a 3D packaging bag having the inflatable outer bag portion 10 a on the bottom side and the non-inflated inner bag portion 10 b on the top side through the transverse heat-sealing seams 41 and 42 and the end sealing seam 43 that heat-sealedly connect multiple layers of films. FIGS. 3 and 6 respectively illustrate the 3D packaging bag after and before inflated.

Moreover, it should be noted that FIG. 5 illustrates the state of the plane cushion material formed through heat-sealing of the 2D heat-sealing seams 30 , it also illustrates the position of the 3D heat-sealing seams 40 , such that one may understand the forming process of the 3D packaging bag more easily.

The inner bag portion 10 b is adaptable to be tucked into the cavity of the outer bag portion 10 a so as to form an accommodating chamber 108 , as is illustrated in FIGS. 2-4 . Thus, the inner bag portion 10 b is adapted for accommodating the object. Then the inner bag portion 10 b that accommodates the object therein is further put in the cavity 106 of the outer bag portion 10 a , such that the outer bag portion 10 a can provide a level of cushioning function through air cushioning, while the inner bag portion 10 b can provide another level of cushioning function. Therefore, impact or shock acting on the outer bag portion 10 a cannot be directly transferred to the object and shaking and impact of the object will not be directly transferred to the outer bag portion 10 a to damage the outer bag portion 10 a . That is to say, the outer bag portion 10 a and the inner bag portion 10 b are coupled to provide cushioning function in a multistage manner.

It is worth mentioning that when the inner bag portion 10 b is utilized for loading the object, after the outer bag portion 10 a is inflated, the external surface of the inner bag portion 10 b may or may not attach with the inner surface of the outer bag portion 10 a . Preferably, according to this embodiment, the inner bag portion 10 b is suspended in the cavity of the outer bag portion 10 a . In other words, there is a buffer gap between the inner bag portion 10 b and the outer bag portion 10 a , which further enhances the cushioning performance. In other words, when the air-storing units 13 of the outer bag portion 10 a are collided or impacted from the outside, the buffer gap can provide a deformation space for the air-storing units 13 , so as to prevent the impact force that acts on the air-storing units 13 from being directly transferred to the object.

Further, the outer bag portion 10 a and the inner bag portion 10 b can be heat-sealedly connected. Preferably, according to this embodiment, the outer bag portion 10 a and the inner bag portion 10 b are integrally formed. That is to say, they are both formed by integrally extending the same air chamber films and valve films. The outer bag portion 10 a and the inner bag portion 10 b are longitudinally arranged and the inner bag portion 10 b can be tucked into the outer bag portion 10 a , such that the inner bag portion 10 b in the outer bag portion 10 a not only serves to package the object, but also further enhance the cushioning function. When there are external impact and shock acting on the outer bag portion 10 a , the inner bag portion 10 b can prevent the object from shaking and stress concentration due to being stuck at a corner.

Besides, the 3D heat-sealing seams 40 further comprise a stopping seam 44 respectively on the two sides of the inner bag portion 10 b heat-sealedly connecting the front and back sides of the inner bag portion 10 b . Referring to FIGS. 3, 5, and 6 , each stopping seam 44 L can be embodied as a heat-sealed seam inclinedly extended from one fringe of the two sides toward the center. Therefore, when the object is accommodated in the accommodating chamber 108 formed by the inner bag portion 10 b again, it will be retained between the two stopping seams 44 . Then, there will be reserved space between the two sides of the object and the inner surfaces of the right side wall 102 and the left side wall 104 , such that when the two sides of the 3D packaging bag formed by the air cushion body 10 receive external shock or impact, the impact force will not be directly transferred to the two sides of the object. Hence, the side cushion performance of the air-filling packaging apparatus can be enhanced.

It is worth mentioning that the 3D heat-sealing seams 40 can be continuous heat-sealed seams or intermittent heat-sealed seams. The transverse heat-sealing seams 41 and 42 can be respectively located at the dividing seam 31 on the top or bottom sides of the air cushion body 10 or be formed with the dividing seam 31 through a first heat-sealing process at the same time. According to the embodiment illustrated in FIG. 5 , the heat-sealing seams 41 and 42 can respectively be an independent heat-sealed seam formed on the bottom or top edge of the air cushion body 10 . The longitudinal end sealing seam 43 can be arranged near by the edge sealing seam 32 of the main channel 151 or be formed with the edge sealing seam 32 of the end sealing seam 43 at once through a first heat-sealing. Alternatively, it can also be an independent heat-sealed seam arranged on the outer edge of the edge sealing seam 32 . When it was arranged in the inner side of the edge sealing seam 32 , the main channel 151 will be formed between the end sealing seam 43 and the main channel sealing seam 33 .

Beside, referring to FIG. 5 , when the inflation inlet 152 of the main channel 151 is arranged on the top side of the air cushion body 10 , the transverse heat-sealing seam 42 on the top side comprises spacedly arranged heat-sealing sections 421 and 422 and an interval 423 left therebetween, wherein the inflation inlet 152 of the main channel 151 is not heat-sealed at the position corresponding to the interval 423 , such that the inflation inlet will not be closed, which allows subsequent inflation operation.

The left side wall 104 and the right side wall 102 can be spacedly arranged in a mostly parallel manner. According to this preferred embodiment of the present invention, more preferably, the left side wall 104 and the right side wall 102 are respectively inclinedly arranged. That is to say, the left side wall 104 is inclinedly extended between the left front side wall 105 and the rear side wall 103 , and the right side wall 102 is inclinedly extended between the right front side wall 101 and the rear side wall 103 .

According to the embodiment illustrated in FIG. 1 , the lengths of the front side walls 101 and 105 are shorter than the length of the rear side wall 103 , such that the left side wall 104 and the right side wall 102 can respectively be inclinedly extended to form a buffer space 1041 and 1021 respectively between the rear side wall 103 and themselves. Certainly, it is understandable that as an alternative mode, the length of the front side walls 101 and 105 may also be longer than the length of the rear side wall 103 .

Correspondingly, the cross section of the air cushion body 10 is mostly in a trapezoidal shape. When the packaging apparatus is arranged in the inner bag portion 10 b , the two sides of the object can respectively be positioned at the first and fourth rows of the bending seams 37 without reaching or extending into the buffer space 1041 and 1021 . Therefore, the two sides of the object may be kept from attaching with the inflated left side wall 104 and right side wall 102 directly and be spaced therewith, such that when the left side wall 104 and the right side wall 102 are collided or impacted from the outside, the external impact force will not be transferred to the object through the left side wall 104 and the right side wall 102 directly. Rather, the buffer space 1041 and 1021 respectively provide deformation space to the left side wall 104 and right side wall 102 . When the left side wall 104 and right side wall 102 are respectively deformed due to receiving the external impact force, the internal air flowing and restoring feature thereof allows them to flexibly recover. When the shock or impact is over, they will automatically recover into their original state without passing the force to the object, so as to remarkably enhance the cushioning performance of the entire multistage cushioning air-filling packaging apparatus. Namely, the sub-air-storing units 131 of the left side wall 104 and the right side wall 102 provide a level of cushion or a first cushion, while the arrangement of the buffer space 1041 and 1021 provides another level of cushion or a second cushion, so as to achieve a cushioning function in a multistage manner.

FIGS. 7-10 illustrate a multistage cushioning air-filling packaging apparatus according to a second preferred embodiment of the present invention. Similarly, according to this preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 A and an inflation valve 20 serving as a self-sealing one-way air inlet. It forms one or more interconnected air-storing units 13 A through a series of 2D heat-sealing seams 30 A and 3D heat-sealing seams 40 A, wherein the air-storing units are circularly arranged to surroundingly form a cavity 106 A.

According to this preferred embodiment of the present invention, the air cushion body 10 A forms an integrally formed inner bag portion 10 b and outer bag portion 10 a , wherein the inner bag portion 10 b is further affixedly connected with the outer bag portion in the 3D heat-sealing step. In other words, by the time the 3D packaging bag is formed by the plane cushion substance through the 3D heat-sealing seams 40 in the 3D heat-sealing step, the inner bag portion 10 b will be tucked into the outer bag portion 10 a and heat-sealedly affixed with the outer bag portion 10 a , which means the inner bag portion 10 b is arranged in the outer bag portion 10 a before inflation. Hence, the inner bag portion 10 b is affixed in the outer bag portion 10 a during the production of the multistage cushioning air-filling packaging apparatus. As as result, the inner bag portion 10 b does not have to be tucked into the inflated outer bag portion 10 a for packaging the object in the packaging site like what is in the embodiment illustrated in FIGS. 1-6 .

It is understandable that it may utilize all kinds of proper way to affix the inner bag portion 10 b in the outer bag portion 10 a . For example, according to the embodiment illustrated in FIG. 8 , the transverse heat-sealing seam 41 A of the outer bag portion 10 a is further heat-sealedly connected with the fringe of the inner bag portion 10 b , which may be equal to integrate the transverse heat-sealing seams 41 and 42 of the embodiment illustrated in FIGS. 1-6 into one transverse heat-sealing seam 41 A so as to heat-sealedly connect the inner bag portion 10 b with the outer bag portion 10 a . It is understandable that the way to connect the inner bag portion 10 b and the outer bag portion 10 a may also include heat-sealedly connecting the inner bag portion with one of the dividing seam 31 A or the bending seam 37 A, wherein the present invention shall not be limited thereto.

Besides, referring to FIGS. 9-10 , the inflation inlet 152 A of the air cushion body 10 A can also be arranged on the bottom side thereof, while, correspondingly, there will be reserved interval at the position of the transverse heat-sealing seam 41 A on the bottom side in the middle corresponding to the inflation inlet 152 A, so as to avoid the inflation inlet 152 A from being closed.

Referring to FIGS. 11A-11B , according to an alternative mode of the above second preferred embodiment of the present invention, the choke seam 38 B is arranged at a proper position at the main channel 151 B, such that the choke seam 38 B can be utilized to divide a plurality of the air-storing units 13 B of the air cushion body 10 B into an inflatable part and non-inflated part arranged along the longitudinal direction, which means the width direction. Correspondingly, referring to FIG. 11A , the four air-storing units 13 B of the top side are uninflatable, while the four air-storing units 13 B integrally extended on the bottom side are inflatable.

That is, when air enters the main channel 151 B via the inflation inlet 151 B, it can then respectively enter the four air-storing units 13 B of the bottom side. Nonetheless, because the choke seam 38 B has heat-sealedly connected the films of the main channel unit 15 B, the air is not allowed to continue entering the four air-storing units 13 B of the top side.

In addition, it is worth mentioning that, according to this embodiment of the present invention, the uninflatable part of the air cushion body 10 B forms the outer bag portion 10 a , while the inflatable part forms the inner bag portion 10 b . It is understandable that the uninflatable part being inversed and heat-sealed may also form a non-inflated outer bag, such that the non-inflated outer bag can serve as a protection, such as preventing the inflatable inner bag from being punctured by hard objects, as well as provide multistage cushioning protection, as FIG. 11B illustrated.

Referring to FIGS. 12A-12B , according to another alternative mode of the above second preferred embodiment of the present invention, the air cushion body 10 C forms the outer bag portion 10 a and the inner bag portion 10 b , wherein the inner bag portion 10 b is formed by one layer of the air chamber films 11 or 12 . Namely, a single layer of film is connected with the outer bag portion 10 a and extended from the top side thereof, wherein the film can be heat-sealedly connected or more preferably, integrally formed. That is to say, an extended section of one of the air chamber film, such as the air chamber film 11 , which continued to extend toward the top side can be utilized for the inner bag portion 10 a . In other words, a layer of the film and a plurality of the air-storing units 13 C on the bottom side are 3D heat-sealed and the film is tucked into the outer bag portion 10 a formed by the air-storing units 13 C in order to form the inner bag portion 10 b.

Referring to FIGS. 13A-13B , according to another alternative mode of the above second preferred embodiment of the present invention, the inner bag portion 10 b and the outer bag portion 10 a formed by the top side and bottom side of the air cushion body 10 D are both inflatable structures. As the figures illustrate, four of the air-storing units 13 D on the bottom side form the outer bag portion 10 a , while four of the air-storing units 13 D on the top side form the inner bag portion 10 b.

More specifically, four of the air-storing units 13 D on the top side are respectively divided by transversely extended air resisting seam 39 D into a plurality of small diameter air-storing units 133 D. Referring to the embodiment illustrated in FIG. 13A , each the air-storing unit 13 D is divided into three small diameter air-storing units 133 D through two air resisting seam 39 D. Thus, a plurality of the small diameter air-storing units 133 D is arranged in the large diameter air-storing units on the bottom side, so as to form the inner bag portion 10 b.

In other words, the inner bag portion 10 b and the outer bag portion 10 a can both provide air cushioning function, so as to allow the 3D packaging bag formed by the air cushion body 10 D to provide cushioning function in a multistage manner. It is understandable that the venting seam 39 D is embodied as a transverse continuous heat-sealed seam to heat-seal two layers of the air chamber films according to this embodiment. According to some alternative mode, there can be spaced heat-sealed seams to ensure that the inner bag portion 10 b may not only communicate along the length direction thereof, but also have heat-sealed blocks in various suitable shapes, such as a plurality of spaced circle, square, triangle, other polygon, and etc.

Referring to FIG. 14 , similarly, according to another alternative mode of the above preferred embodiment of the present invention, the air cushion body 10 E forms the inner bag portion 10 b and the outer bag portion 10 a and the stopping seams 44 E are formed on the two sides of the non-inflated inner bag portion 10 b . Moreover, according to this alternative mode, the stopping seams 44 E are not inclinedly extended; instead, they are extended along a vertical direction. Therefore, when the non-inflated inner bag portion 10 b is tucked into the outer bag portion 10 a for packaging the object, the object will be retained between the two stopping seams 44 .

More specifically, referring to FIG. 14 , the two stopping seams 44 are spacedly arranged. Each stopping seam 44 may be a continuous heat-sealed seam or an intermittent heat-sealed seam, while it keeps a predetermined distance from the fringe of the two sides of the inner bag portion 10 b and extends longitudinally. As a result, when the object is retained between the two stopping seams 44 , the object is spaced to the side walls 104 E and 102 E of the outer bag portion 10 a of the air cushion body 10 E, so as to prevent force acting on the side walls 104 E and 102 E be directly transferred to the object, such that the cushioning function can be enhanced.

FIGS. 15-20 illustrate a multistage cushioning air-filling packaging apparatus according to a third preferred embodiment of the present invention. Similarly, it comprises at least an air cushion body 10 F and an inflation valve 20 serving as a self-sealing one-way air inlet. It forms one or more interconnected air-storing units 13 F through a series of 2D heat-sealing seams 30 F and 3D heat-sealing seams 40 F, wherein the air-storing units are circularly arranged to surroundingly form a cavity 106 F.

According to this preferred embodiment of the present invention, the air cushion body 10 F forms an integrally formed inner bag portion 10 b and outer bag portion 10 a . Besides, a plurality of the air-storing units 13 F form an inflatable air-storing unit 13 a , an uninflatable air-storing unit 13 b through the arrangement of the choke seam 38 , and a reinforcing cushion unit 13 c that has a bottom side.

More specifically, referring to FIGS. 15-18 , the transverse heat-sealing seam 41 F of the bottom side of the 3D heat-sealing seams 40 is arranged between two of the adjacent air-storing units 13 F on the bottom side, so as to have one or more of the air-storing units 13 on the outermost side of the bottom side form the reinforcing cushion unit 13 c . In other words, the transverse heat-sealing seam 41 F is not arranged on the fringe of the bottom side of the air cushion body 10 F, but arranged on the dividing seam 31 F between two adjacent air-storing units 13 F. Alternatively, the dividing seam 31 F and the transverse heat-sealing seam 41 F can be formed at the same time in a first heat-sealing process, such that the two sides of the transverse heat-sealing seam 41 F along a longitudinal direction are respectively the reinforcing cushion unit 13 c and the inflatable air-storing unit 13 a.

Similarly, when the inflation inlet 152 F is arranged on the bottom side of the air cushion body 10 F, the transverse heat-sealing seam 41 F will comprise two transverse heat-sealing sections 411 F and 412 F and the interval between the two transverse heat-sealing sections 411 F and 412 F is at the position corresponding to the inflation inlet 152 F so as to prevent it from being closed in the heat-sealing process for forming the transverse heat-sealing seam 41 F.

It is understandable that referring to FIG. 20 , when the object M is packaged in the multistage cushioning air-filling packaging apparatus, the reinforcing cushion unit 13 F on the bottom side provides a first air cushioning function on the bottom side thereof. Besides, the inflatable air-storing unit 13 a at the inner side of the reinforcing cushion unit 13 F provides another level of air cushioning function. Moreover, the inner bag portion 10 b formed by the non-inflated air-storing units 13 b further provides another level of cushioning function. Hence, the 3D packaging bag formed by the air cushion body 10 F according to this preferred embodiment of the present invention can provide cushioning function in a multistage manner. In other words, this structural design strengthens its overall cushioning performance, especially on the bottom side.

Besides, referring to FIGS. 15-16 , according to this embodiment, the longitudinal end sealing seam 43 F of the 3D heat-sealing seams 40 can also be formed at the position corresponding to the main channel sealing seam 33 F. Alternatively, the main channel sealing seam 33 F and the end sealing seam 43 F can be formed at once in the first heat-sealing process, so as to connect the head and tail of the air cushion body 10 F. Similarly, the transverse heat-sealing seams 41 F and 42 F of the 3D heat-sealing seams 40 respectively heat-sealedly connect the top side and bottom side of the air cushion body 10 , so as to form the cavity 106 F. In addition, similar with the above second embodiment, the transverse heat-sealing seams 41 F and 42 F may also be formed together, such that the outer bag portion 10 b can be affixedly connected with the inner bag portion 10 a . Therefore, it will not cost labor to tuck the outer bag portion 10 b into the inflated inner bag portion 10 a on the packaging site.

Similarly, the longitudinally arranged stopping seams 44 F on the two sides of the inner bag portion 10 b can serve to retain and limit the object M, such that the object M can be spaced with the side walls formed on the two sides of the air cushion body 10 F, so as to reinforce the side cushioning function.

Moreover, referring to FIG. 19 , similar with the above first embodiment, the left and right side walls can be inclinedly arranged and the lengths of the front and rear side walls are different, such that the cross section thereof will be in a trapezoidal shape, which can then further enhance the side cushion performance of the multistage cushioning air-filling packaging apparatus according to this preferred embodiment of the present invention.

It is worth mentioning that the multistage cushioning air-filling packaging apparatus of the present invention can be utilized to accommodate the object M in the accommodating chamber 108 F of the outer bag portion 10 b . For example, a multistage cushioning air-filling packaging apparatus can be utilized to accommodate an object M in the inside thereof and match with other packing case or packaging box to store or transport the object M. According to the application of this preferred embodiment illustrated in FIG. 21 , the object M can be packaged by coupling two of the multistage cushioning air-filling packaging apparatuses. In other words, the present invention provides a packaging assembly, which comprises two of the multistage cushioning air-filling packaging apparatuses, wherein two extremities of the object M are respectively accommodated in an accommodating chamber 108 F of the outer bag portion 10 b of the multistage cushioning air-filling packaging apparatus, wherein the entire package is put in other packing case or packaging box for storing or transporting the object M. Besides, the structure of the multistage cushioning air-filling packaging apparatus according to the present invention can significantly enhance the cushioning performance in all sides, so as to prevent the object M from being damaged by external impact or shock.

FIGS. 22-23 illustrate an alternative mode of the above third preferred embodiment of the present invention. According to this alternative mode, the inner bag portion 10 b can also be removed from the above third preferred embodiment. Referring to the figure, the air cushion body 10 G forms a plurality of the air-storing units 13 G, where the air-storing units 13 G for forming the cavity 106 G are defined, such that a packaging body is formed. Besides, the reinforcing cushion unit 13 c is formed by one or more of the air-storing units 13 G on the bottom side through the transverse heat-sealing seam 41 G on the bottom side.

According to this embodiment, the transverse heat-sealing seam 41 G on the bottom side seals on the bottom side of the 3D packaging bag formed by the multistage cushioning air-filling packaging apparatus. Nonetheless, the other side of the 3D packaging bag does not require the arrangement of another transverse heat-sealing seam 42 F, such that the opening 107 G can be formed on the top side of the 3D packaging bag. The object is then able to be directly put into the cavity 106 G through the opening 107 G.

Similarly, each of the air-storing units 13 G is divided into a plurality of communicated sub-air-storing units 131 G through a plurality of the dividing seams 37 G, so as to form a plurality of side walls, wherein the front and rear side walls are not equally long, such that the left and right side walls can be inclinedly extended, which can reinforce the cushioning performance of the left and right sides. The reinforcing cushion unit 13 c of the bottom side can enhance the cushioning performance of the bottom side.

It is understandable that because the transverse heat-sealing seam 41 G heat-sealedly connects the front and rear side walls, a buffer space is formed among the adjacent air-storing units 13 a on the left and right sides and the reinforcing cushion unit 13 c , such that the reinforcing cushion unit 13 c gain a deformation space based on the establishment of the buffer space, which enhances the cushioning function on the bottom side. Further, when the reinforcing cushion unit 13 c is a relatively large diameter air chamber unit and the adjacent air-storing unit 13 a is a relatively small diameter air chamber unit, the buffer space will be increased, so as to provide more deformation space for the reinforcing cushion unit 13 c.

In addition, when the bottom side of the packaging body formed by the air-storing units 13 a is a small diameter air chamber unit, which means what next by the transverse heat-sealing seam 41 G and in the inner side thereof is a small diameter air chamber unit and what in the two sides of the small diameter air chamber unit are large diameter air chamber units, due to the tautening of connection between the front and back side walls by the transverse heat-sealing seam 41 G, the small diameter air chamber unit will be hidden between the large diameter air chamber units on the two sides thereof. Therefore, the small diameter air chamber unit will not be affected by external impact or shock, so as to further enhance the cushioning performance on the bottom side of the 3D packaging bag formed by the multistage cushioning air-filling packaging apparatus.

FIGS. 24-26 illustrate the air-filling packaging apparatus according to a fourth preferred embodiment of the present invention. According to the this preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 H. Namely, either one of the air cushion body 10 H forms a 3D packaging bag or a plurality of the air cushion bodies 10 H form the 3D packaging bag through heat-sealing connecting, such as adhesive bonding, heat-sealing, and etc. The embodiment illustrated in FIGS. 24-26 is formed by one air cushion body 10 H. More specifically, referring to FIG. 71A , the air cushion body 10 H comprises at least two air chamber films 11 and 12 forming the 3D packaging bag comprising one or more interconnected air-storing units 13 H through a series of 2D heat-sealing seams 30 H and 3D heat-sealing seams 40 H, wherein each of the air-storing units 13 H forms an air storage chamber 14 that is able to store gas therein, which is similar with it in the above first embodiment.

Person skilled in the art should be able to understand that the 2D heat-sealing seams 30 H are for heat sealing the multiple films into a 2D cushion material, as is illustrated in FIG. 26 . The 3D heat-sealing seams 40 H are additional heat-sealing on the above 2D cushion material to make the air-filling packaging apparatus into a 3D packaging device that has a 3D structure and can accommodate the object, as FIG. 24 illustrate. The 2D heat-sealing seams 30 H and the 3D heat-sealing seams 40 H can connect multiple layers of films together through adhesive bonding, heat-sealedly connection, and etc. Preferably, according to this embodiment, the 2D heat-sealing seams 30 H and the 3D heat-sealing seams 40 H are both formed through heat-sealing technology.

More specifically, the 2D heat-sealing seams 30 H comprise a plurality of dividing seams 31 H dividing the two air chamber films 11 and 12 into a plurality of the air-storing units 13 H. Preferably, each row of the dividing seams 31 H is formed by heat-sealing technology that heat-sealedly connects two layers of the air chamber films 11 and 12 so as to form a row of the dividing seam 31 H between two adjacent air-storing units 13 H. The dividing seam 31 H may be an continuous heat-sealed line so as to have a plurality of the air-storing units 13 H be independent to one another. It is understandable that the dividing seam 31 H on the top side and the bottom side can respectively become a top side boundary seam and a bottom side boundary seam of the air cushion body 10 H, as FIG. 26 illustrate. The dividing seam 31 H may also be an intermittent heat-sealed line so as to have a plurality of the air-storing units 13 H be interconnected. The air-storing unit 13 H can be in various shape, such as linear, circular, polygon, irregular, and etc. Referring to FIGS. 24-26 , the air cushion body 10 H according to the present invention may comprise a plurality of air-storing pillars abreast arranged, but the present invention shall not be limited thereto.

According to this preferred embodiment, referring to FIG. 71A , the air cushion body 10 H further comprises an inflation valve 20 formed by at least two valve films 21 and 22 . The two valve films 21 and 22 of the inflation valve 20 and the air chamber films 11 and 12 are overlappedly arranged. Besides, an air inlet channel 23 is formed between the valve films 21 and 22 for inflating to the air storage chamber 14 . It is understandable that the lengths of the valve films 21 and 22 are shorter than the lengths of the air chamber films 11 and 12 . When the air storage chamber 14 is inflated via the air inlet channel 23 and the air pressure in the air storage chamber 14 has attained the predetermined required value, the air pressure in the air storage chamber 14 will act on the valve films 21 and 22 so as to attach the valve films 21 and 22 on one of the air chamber film, which closes the air inlet channel 23 and makes the inflation valve 20 serve as a one-way valve. When each air-storing unit 13 H has at least an air inlet channel 23 formed therein and each of the air-storing units 13 H is independent to one another, even if one of the air-storing units 13 H is damaged and leaks, the rest of the air-storing units 13 H will not be affected, but still serve to provide the air cushion performance.

It is understandable that the air chamber films 11 and 12 of the air cushion body 10 H and the valve films 21 and 22 of the inflation valve 20 can respectively be made of various suitable membrane materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, composite film, and etc, wherein the present invention shall not be limited thereto, as long as suitable flexible films is utilized. It is worth mentioning that in order to enhance the one-way sealing function, the valve films 21 and 22 of the inflation valve 20 can also be self-adhesive films acquired by adding chemical composition to the above films.

The air cushion body 10 H further comprises a main channel unit 15 H connected with each of the air-storing units 13 H or, preferably, integrally extended from each of the air-storing units 13 H. More specifically, according to this preferred embodiment, the extending directions of the main channel unit 15 H and the air-storing unit 13 H are perpendicular to each other. For example, according to this embodiment, each the air-storing unit 13 H is extended along a transverse and horizontal direction, while the main channel unit 15 H is extended along a longitudinal direction. The main channel unit 15 H forms a main channel 151 H that has an inflation inlet 152 H. When the inflation inlet 152 H has an inflation nozzle arranged thereat for conducting an inflation process, gas will enter the main channel 151 H from the inflation inlet 152 H along a longitudinal direction, and enter each the air-storing unit 13 H along a transverse direction. Then, when the air pressure of each the air storage chamber 14 reaches a predetermined value, the valve films 21 and 22 of the inflation valve 20 will attached on one of the air chamber films 11 and 12 , so as to self-seal and prevent the inflated gas from reversing into the main channel 151 H.

It is worth mentioning that, it is understandable that the main channel unit 15 H can be formed by two layers of the air chamber films 11 and 12 , two layers of the valve films 21 and 22 , or either one layer of the air chamber films 11 and 12 and either one layer of the valve films 21 and 22 .

Referring to FIG. 26 , the 2D heat-sealing seams 30 H further comprise a continuously sealed edge sealing seam 32 H respectively on the left and right sides and a continuously sealed main channel sealing seam 33 H on the left side of the air cushion body 10 H, wherein the main channel 151 H is formed between the left edge sealing seam 32 H and the main channel sealing seam 33 H. It is understandable that the edge sealing seam 32 H is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealingly connect the two air chamber films 11 and 12 . The main channel sealing seam 33 H is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealedly connect the two air chamber films 11 and 12 and the two valve films 21 and 22 respectively, as FIG. 71A illustrate. For example, the main channel sealing seam 33 H on the up and down sides that was formed through a first heat-sealing technology respectively heat-sealedly connects the air chamber film 11 and the valve film 21 and heat-sealedly connects the air chamber film 12 and the valve film 22 .

Referring to FIG. 26 , each the air-storing unit 13 H comprises two spaced gas duct seams 34 H adjacent to the main channel 151 H and formed through heat-sealedly connecting the air chamber films 11 and 12 and the valve films 21 and 22 . The air inlet channel 23 formed by the valve films 21 and 22 are arranged between the two gas duct seams 34 H.

Referring to FIG. 71A , the valve films 21 and 22 are further heat-sealedly connected with the air chamber film 11 through a plurality of connecting seams 35 H, such that when the air pressure in the air storage chamber 14 attained a predetermined value, the air pressure will act on the valve films 21 and 22 and because of the arrangement of the connecting seams 35 H, the valve films will be pushed toward the air chamber film 11 and eventually be attached on the air chamber film 11 , so as to close the air inlet channel 23 . That is to say, the connecting seam 35 H heat-sealedly connects the two valve films 21 and 22 and the air chamber film 11 . Besides, referring to FIG. 26 , the shape of each the connecting seam 35 H allows it to further prevent the air from backflow. In other words, when the air in the air storage chamber 14 is going to flow back, it will be obstructed by the connecting seam 35 H and cannot return into the main channel 151 H easily.

In addition, when the 2D heat-sealing seams 30 H are being formed through heat-sealing, the air inlet channel 23 of the valve films 21 and 22 of the inflation valve 20 can be formed through the arrangement of a heatproof barrier device. Then the heatproof barrier device can be removed after the heat-sealing process. According to this embodiment, referring to FIGS. 26 and 71A , a heatproof layer 24 is arranged between the valve films 21 and 22 of the inflation valve 20 and attached with the inner surface of one of the valve films 21 and 22 . The heatproof layer 24 can be embodied as thermostable inks and etc. As a result, when the main channel sealing seam 33 H is formed through heat-sealing, the two valve films 21 and 22 will not be heat-sealedly connected, such that the air inlet channel 23 can be connected with the main channel 151 H and the access thereof will not be closed due to the heat-sealing.

According to this preferred embodiment, the main channel 151 H is formed by the two air chamber films 11 and 12 , the heatproof layer 24 and the valve films 21 and 22 respectively have extending section extended into the main channel 151 , and the 2D heat-sealing seams 30 further comprise a joint seam 36 H longitudinally and spacingly arranged at the position corresponding to the extending section of the heatproof layer 24 . Because of the arrangement of the heatproof layer 24 , the joint seam 36 H respectively connects the two air chamber films 11 and 12 and the two valve films 21 and 22 , while the two valve films 21 and 22 are not heat-sealedly connected with each other. The arrangement of the joint seam 36 H allows adjacent valve films 21 and 22 and the correspondingly connected air chamber films 11 and 12 to be expanded together to open the corresponding air inlet channel 23 when air enters the main channel 151 H during the inflation of the air cushion body 10 .

The 2D heat-sealing seams 30 H further comprise a plurality intermittent bending seams 37 H, wherein the inflated air cushion body 10 H is adaptable for bending along the bending seams 37 H, such that the air cushion body 10 H can form a plurality of side walls. More specifically, the bending seam 37 H divides each the air-storing unit 13 into a plurality of sub-air-storing units 131 H. The bending seam can be arranged in the middle of the air-storing unit 13 H and respectively form a connecting channel 132 H on the two sides thereof, such that the adjacent sub-air-storing units 131 H can be interconnected and communicated, as FIG. 26 illustrated. It is understandable that the bending seam 37 H can also be arranged on the two sides of the air-storing units 13 H, while the connecting channel 132 H is arranged in the middle of the air-storing units 13 H. Correspondingly, it is understandable that each the bending seam 37 H heat-sealedly connects two layers of the air chamber films 11 and 12 .

Further, according to the embodiment illustrated in FIGS. 24-26 , the 2D heat-sealing seams 30 H comprise eight rows of the bending seams 37 H, such that the air cushion body 10 H is adaptable for being bent along the eight bending seams 37 H to form the right front side wall 101 H, right side wall 102 H, rear side wall 103 H, left side wall 104 H, and left front side wall 105 H. The above mentioned side walls 101 - 105 H are bent to form a cavity 106 H with an opening 107 H on the top side thereof. Namely, the side walls 101 - 105 H are surroundingly arranged and the air-storing units 13 H respectively form a ringlike air-storing pillar.

Correspondingly, referring to FIGS. 24 and 26 , the 3D heat-sealing seams 40 H comprises a transverse heat-sealing seam 41 H on the bottom side heat-sealing and connecting the bottom sides the front side walls 101 H and 105 H and the rear side wall 103 H, so as to seal off the bottom side of the multistage cushioning air-filling packaging apparatus. The 3D heat-sealing seams 40 H further comprise a longitudinal end sealing seam 43 H heat-sealedly connecting the right front side wall 101 H and the left front side wall 105 H along the longitudinal direction which means the air cushion body 10 H is circularly arranged and the head and tail thereof are connected. Thus, the air cushion body 10 H is able to form a 3D packaging bag having the cavity 106 H through the transverse and horizontal heat-sealing seam 41 H and the end sealing seam 43 H that heat-sealedly connect multiple layers of films, as FIG. 24 illustrate.

According to this preferred embodiment of the present invention, the 3D heat-sealing seams 40 H further comprise a section sealing seam 45 H respectively formed on the two sides of the air cushion body 10 H, which are respectively embodied as an intermittent heat-sealed seam, so as to form a flank cushion portion 16 H respectively on the two sides of the multistage cushioning air-filling packaging apparatus. Referring to FIG. 24 , the sub-air-storing unit 131 H in the middle forms a packaging body 17 H having the flank cushion portion 16 H respectively integrally extended from the two sides thereof, where air may flow thereamong. The packaging body 17 H forms the cavity 106 H for packaging the object, while the flank cushion portions 16 H on the two sides are for enhancing side cushioning function. In other words, the flank cushion portion 16 H provides a first cushioning function on a side and the packaging body 17 H provides another level of air cushioning function, such that the 3D packaging bag formed by the air cushion body 10 according to this preferred embodiment of the present invention can provide cushioning function in a multistage manner.

When the air cushion body 10 H is formed by two layers of the air chamber films 11 and 12 , the section sealing seam 45 H heat-sealedly connects four layers of the films respectively, which means that it heat-sealedly connects two of the air chamber films 11 and 12 of the front and back sides respectively along a longitudinal direction, as FIGS. 24 and 26 illustrate. It is understandable that the section sealing seam 45 H is embodied as an intermittent heat-sealed seam, so as to allow air communication between the flank cushion portion 16 H and the packaging body 17 H or, in other words, form the connecting channel 132 H therebetween, such that the flank cushion portion 16 H and the packaging body 17 H can be inflated together in an inflation process. Besides, it is worth mentioning that the section sealing seam 45 H can be arranged either in the middle portion of the air-storing unit 13 H or the two sides thereof and integrally connected with the dividing seams 31 H of the two sides, where the present invention shall not be limited here.

Moreover, it should be noted that though FIG. 26 illustrated the 2D cushion material formed through heat-sealing of the 2D heat-sealing seams 30 H, it also illustrates the position of the 3D heat-sealing seams 40 H, such that one may understand the forming process of the 3D packaging bag more easily.

It is worth mentioning that the transverse heat-sealing seam 41 H can be located at the dividing seam 31 on the bottom side of the air cushion body 10 H or be formed with the dividing seam 31 H through a first heat-sealing process at the same time. According to the embodiment illustrated in FIG. 26 , the heat-sealing seams 41 H can be independent heat-sealed seams respectively formed on the bottom and top edges of the air cushion body 10 H instead of being arranged at the dividing seam 31 of the bottom side. The longitudinal end sealing seam 43 can be arranged near by the edge sealing seam 32 H of the main channel 151 H or be formed with the edge sealing seam 32 H of the end sealing seam 43 H at once through a first heat-sealing. Alternatively, it can also be an independent heat-sealed seam arranged on the outer edge of the edge sealing seam 32 H. When it was arranged in the inner side of the edge sealing seam 32 H, the main channel 151 H will be formed between the end sealing seam 43 H and the main channel sealing seam 33 H. Alternatively, the longitudinal end sealing seam 43 can be arranged at the position of or near by the main channel sealing seam 33 H. The present invention shall not be limited here, as long as the head and tail of the air cushion body 10 is connected. Besides, the sealing seam can either be continuous or spaced.

More specifically, referring to FIGS. 24 and 26 , according to this preferred embodiment, the right side wall 102 H comprises two sub-right side walls 1022 H, while the left side wall 104 H also comprises two sub-left side walls 1042 H. Referring to FIG. 26 , it is described from the left to the right as follows for the convenience of description. The sub-air-storing unit 131 H in the left of the first row of the bending seam 37 H is for forming the right front side wall 101 H. One the sub-right side wall 1022 H is respectively formed between the first row and fourth row of the bending seams 37 H and the first row of the section sealing seam 45 H. According to the stretch-out view as is illustrated in FIG. 26 , the first row of the section sealing seam 45 H is expanded and divided into two rows, where the flank cushion portion 16 H of the right side is formed between the two rows. The rear side wall 103 H is formed between the fourth row and the fifth row of the bending seams 37 H. One the sub-left side wall 1042 H is formed between the fifth row and eighth row of the bending seams and the second row of the section sealing seam 45 H respectively. Moreover, the second row of the section sealing seam 45 H, according to the stretch-out view as FIG. 26 illustrated, is expanded and divided into two rows, where the flank cushion portion 16 H of the left side is formed between the two rows and the left front side wall 105 is formed by the right side of the eighth row of the bending seam.

It is understandable that the side walls 101 - 105 H are respectively formed by the sub-air-storing units 131 H integrally extended from the air-storing unit 13 H along the length direction thereof. It is understandable that the quantity of the bending seam 37 H can be determined based on the needs. According to other embodiments, it is possible to have no bending seam 37 H, more bending seams 37 H, or less bending seams 37 H arranged. According to this preferred embodiment of the present invention, a plurality of packaging body main air-storing units 131 a and a plurality of flank air-storing units 131 b are formed by a plurality of sub-air-storing units 131 H arranged along the length direction. According to this preferred embodiment, each the air-storing unit is divided into seven of the packaging body main air-storing units 131 a and six of the flank air-storing units 131 b along the length direction.

Referring to FIG. 25 , according to this embodiment of the present invention, each the flank cushion portion 16 H is formed by three flank air-storing units 131 b , so as to respectively form a cushion base 161 H and two cushion waists 162 H integrally extended from the two sides of the cushion base 161 H, such that the cross section of each the flank cushion portion 16 H is mostly triangular, so as to enhance the cushioning performance. Besides, a buffer gap 163 H is formed between the cushion base 161 H and the two cushion waists 162 H and a buffer space 164 H is respectively formed between the left and right side walls of the packaging body 17 H and the flank cushion portion 16 H based on the arrangement of the section sealing seams 45 H between the flank cushion portion 16 H and the packaging body 17 H. In other words, the arrangement of the buffer gap 163 H and the buffer space 164 H provides deformation space for the flank cushion portion 16 H, so as to enhance the elastic restitution performance of the flank cushion portion, instead of have it transfer the impact force received on the side to the object in the inside. Besides, it is understandable that the buffer gap 163 H may also be utilized for accommodating the accessories of the object. For instance, if the object is a laptop, the buffer gap 163 H can be utilized for accommodating its accessories, such as power core, mouse, and etc.

It is understandable that when the lengths of the left side wall 104 H and right side wall 102 H are shorter, they can be hidden among the front and rear side walls 101 H and 105 H and 103 H and the flank cushion portion 16 H, such that the left side wall 104 H and right side wall 102 H will not have to bear external impacts. As a result, the cushioning performance of the multistage cushioning air-filling packaging apparatus can be further enhanced.

It is worth mentioning that the flank cushion portion 16 H shall not be limited in a triangle shape illustrated in FIGS. 24-35 . Rather, it may also be embodied into other shapes. For instance, if there is no dividing seam 37 H, it can be in mostly an arc shape. If there are three bending seams 37 H arranged, the cross section thereof may have some polygon structure. Alternatively, it may have an irregular heat-sealed seam arranged thereon so as to form other irregular shape, as long as it can form an inflatable structure to provide air cushioning function.

Referring to FIG. 24 , when utilizing the multistage cushioning air-filling packaging apparatus according to this embodiment of the present invention, an inflation nozzle of an air pump has to be put in the inflation inlet 152 H of the top side to conduct the inflation process. The air will enter the main channel 151 H, proceed rightward to respectively and successively enter the sub-air-storing unit 131 a of the right front side wall 101 H, the sub-air-storing unit 131 a of the sub-right side wall 1022 H, and the sub-air-storing unit 131 b of the flank cushion portion 17 H of the right, turn backward to respectively and successively enter the sub-air-storing unit 131 a of the sub-right side wall 1022 H of the back side, the sub-air-storing unit 131 a of the rear side wall 103 H, the sub-air-storing unit 131 a of the sub-left side wall 1042 H of the back side, and the sub-air-storing unit 131 b of the flank cushion portion 17 H of the left side, and enter the sub-air-storing units 131 a of the left front side wall 105 H and the sub-left side wall 1042 H of the front side, so as to finish the inflation. The self-sealing function can keep the air stored in each the air-storing unit 13 H, so as to make an inflated 3D packaging bag. The object can be put into the cavity 106 H via the opening 107 H, such that the 3D packaging bag can provide air cushioning function for the object.

FIGS. 27-31 illustrate a multistage cushioning air-filling packaging apparatus according to a fifth preferred embodiment of the present invention, which has a similar structure with the above fourth preferred embodiment. Nonetheless, the differences include that the air cushion body 10 I forms an inner bag portion 10 b and an outer bag portion 10 a , wherein the inner bag portion 10 b is suitable for being arranged in the outer bag portion 10 a , such that the inner bag portion 10 b and the outer bag portion 10 a can provide cushioning function in a multistage manner.

More specifically, the air cushion body 10 I is divided into a plurality of transverse extended air-storing units 13 I through a series of transverse extended dividing seams 31 I, wherein each the air-storing unit 13 I is divided along its length direction into a plurality of sub-air-storing units 131 I through a plurality of bending seams 37 I.

Referring to FIGS. 27 and 29 , the 2D heat-sealing seams 30 I further comprises a choke seam 38 I sealing off the air inlet channel of the two air-storing units 13 I, as the figure illustrate, of the air-storing units 13 I on the top side of the air cushion body 10 I. Namely, the choke seam can be arranged adjacent to the tail of the air inlet channel 23 to heat-sealedly connect the two air chamber films 11 and 12 and the two valve films 21 and 22 , so as to make each the air-storing unit 13 I uninflatable and form non-inflated air-storing pillar.

Correspondingly, the arrangement of the choke seam 38 I can divide a plurality of transversely extended air-storing units 13 into a plurality of inflatable air-storing units 13 a and a plurality of uninflatable air-storing units 13 b arranged longitudinally. For instance, referring to FIG. 29 , the two air-storing units on the top side are uninflatable, which are, according to this embodiment of the present invention, to form an inner bag portion 10 b , while the four inflation units 13 a on the bottom side are inflatable, so as to form an outer bag portion 10 a . In other words, according to this preferred embodiment of the present invention, it provides cushioning function in a multistage manner through the inflatable outer bag portion 10 a and the non-inflated inner bag portion 10 b.

The inner bag portion 10 b is adaptable to be tucked into the cavity 106 I of the outer bag portion 10 a so as to form an accommodating chamber 108 I, as FIGS. 28 and 30 illustrate. Thus, the inner bag portion 10 b is adapted for accommodating the object M. Then the inner bag portion 10 b that accommodates the object therein is further put in the cavity 106 I of the outer bag portion 10 a , such that the outer bag portion 10 a can provide a level of cushioning function through air cushioning, while the inner bag portion 10 b can provide another level of cushioning function. Therefore, impact or shock acting on the outer bag portion 10 a cannot be directly transferred to the object M and shaking and impact of the object M will not be directly transferred to the outer bag portion 10 a to damage the outer bag portion 10 a . That is to say, the outer bag portion 10 a and the inner bag portion 10 b are coupled to provide cushioning function in a multistage manner.

It is worth mentioning that when the inner bag portion 10 b is utilized for loading the object, after the outer bag portion 10 a is inflated, the external surface of the inner bag portion 10 b may or may not attach with the inner surface of the outer bag portion 10 a . Preferably, according to this embodiment, the inner bag portion 10 b is suspended in the cavity of the outer bag portion 10 a . In other words, there is a buffer gap between the inner bag portion 10 b and the outer bag portion 10 a , which further enhances the cushioning performance. In other words, when the air-storing units 13 of the outer bag portion 10 a are collided or impacted from the outside, the buffer gap can provide a deformation space for the air-storing units 13 I, so as to prevent the impact force that acts on the air-storing units 13 I from being directly transferred to the object.

Further, the outer bag portion 10 a and the inner bag portion 10 b can be heat-sealedly connected. Preferably, according to this embodiment, the outer bag portion 10 a and the inner bag portion 10 b are integrally formed. That is to say, they are both formed by integrally extending the same air chamber films and valve films. The outer bag portion 10 a and the inner bag portion 10 b are longitudinally arranged and the inner bag portion 10 b can be tucked into the outer bag portion 10 a , such that the inner bag portion 10 b in the outer bag portion 10 a not only serves to package the object, but also further enhance the cushioning function. When there are external impact and shock acting on the outer bag portion 10 a , the inner bag portion 10 b can prevent the object from shaking and stress concentration due to being stuck at a corner.

Similarly, the 3D heat-sealing seams 40 I further comprises two intermittent section sealing seams 45 I arranged on the two sides of the air cushion body 10 I and connecting the front and back sides thereof, so as to turn the air cushion body 10 I of the ringlike arranged air-storing units 13 I into a packaging body 17 I and two flank cushion portion 16 I. According to this preferred embodiment, each flank cushion portion 16 I comprises four bending seams 37 I arranged thereon, such that the part of each the air-storing unit 13 I here is divided into five sub-air-storing units 131 I. Namely, the cushion waist of the above embodiment is further divided into a plurality of cushion side walls.

In addition, according to this preferred embodiment, the transverse heat-sealing seam 41 I of the bottom side of the 3D heat-sealing seams 40 I is arranged between two the adjacent air-storing units 13 I on the bottom side, so as to respectively form the air-storing unit 13 a and the reinforcing cushion unit 13 c on the two sides of the transverse heat-sealing seam 41 I. The reinforcing cushion unit 13 c provides reinforced cushioning function on the bottom side.

It is understandable that because the transverse heat-sealing seam 41 I heat-sealedly connects the front and rear side walls, a buffer space is formed among the adjacent air-storing units 13 a on the left and right sides and the reinforcing cushion unit 13 c , such that the reinforcing cushion unit 13 c gain a deformation space based on the establishment of the buffer space, which enhances the cushioning function on the bottom side. Further, when the reinforcing cushion unit 13 c is a relatively large diameter air chamber unit and the adjacent air-storing unit 13 a is a relatively small diameter air chamber unit, the buffer space will be increased, so as to provide more deformation space for the reinforcing cushion unit 13 c.

In addition, when the bottom side of the packaging body formed by the air-storing units 13 a is a small diameter air chamber unit, which means what next by the transverse heat-sealing seam 41 I and in the inner side thereof is a small diameter air chamber unit and what in the two sides of the small diameter air chamber unit are large diameter air chamber units, due to the tautening of connection between the front and back side walls by the transverse heat-sealing seam 41 I, the small diameter air chamber unit will be hidden between the large diameter air chamber units on the two sides thereof. Therefore, the small diameter air chamber unit will not be affected by external impact or shock, so as to further enhance the cushioning performance on the bottom side of the 3D packaging bag formed by the multistage cushioning air-filling packaging apparatus.

It is understandable that the transverse heat-sealing seam 41 I can be arranged on the dividing seam 31 between the corresponding air-storing unit 13 a and the reinforcing cushion unit 13 c or be formed on the bottom side with dividing seam 31 I on the bottom side at the same time through a first heat-sealing process. It is understandable that the transverse heat-sealing seam 41 I can be a continuous sealing seam or an intermittent sealing seam. Besides, when the transverse heat-sealing seam 41 I and the dividing seam 31 I on the bottom side are formed at once through a first heat-sealing process and the transverse heat-sealing seam 41 I is a intermittent sealing seam, the air-storing units 13 a and the reinforcing cushion unit 13 c on the bottom side can communicate with each other, so as to provide a reinforced cushioning function on the bottom side through the flow and distribution of the air between the air-storing unit 13 a and the reinforcing cushion unit 13 c of the bottom side.

Besides, according to this embodiment of the present invention, the transverse heat-sealing seam 41 I on the bottom side is not extended to the position of the main channel 151 I, such that it will not close the main channel 151 I. Referring to FIG. 29 , the inflation inlet 151 I can be arranged on the top side, while according to other embodiments, it can certainly be arranged on the bottom side as well. The 3D heat-sealing seams 40 further comprise a transverse heat-sealing seam 42 I on the top side to connect the front and rear parts of the top side of the uninflatable inner bag portion 10 b , such that after the entire non-inflated inner bag portion 10 b is tucked into the outer bag portion 10 a , the bottom side thereof is closed, but there is an opening on the top side thereof. Correspondingly, the transverse heat-sealing seam 42 I comprises two heat-sealing sections 421 I and 422 I to form the gap at the position corresponding to the main channel 151 I, where no heat-sealing connection is formed, such that the inflation inlet 152 I will not be closed. Similarly, the transverse heat-sealing seam 41 I on the bottom side comprises heat-sealing sections 411 I and 412 I to form the gap at the position corresponding to the main channel 151 I, where no heat-sealing connection is formed, such that the main channel 151 I will not be closed. Correspondingly, it is understandable that each of the above mentioned heat-sealing sections 411 I, 412 I, 421 I, and 422 I can be a continuous sealing seam or an intermittent sealing seam.

It is worth mentioning that the multistage cushioning air-filling packaging apparatus of the present invention can be utilized to accommodate the object M in the accommodating chamber 108 I of the outer bag portion 10 b . For example, a multistage cushioning air-filling packaging apparatus can be utilized to accommodate an object M in the inside thereof and match with other packing case or packaging box to store or transport the object M. According to the application of this preferred embodiment to illustrated in FIG. 31 , the object M can be packaged by coupling two of the multistage cushioning air-filling packaging apparatuses. In other words, the present invention provides a packaging assembly, which comprises two of the multistage cushioning air-filling packaging apparatuses, wherein two extremities of the object M are respectively accommodated in an accommodating chamber 108 I of the outer bag portion 10 b of the multistage cushioning air-filling packaging apparatus, wherein the entire package is put in other packing case or packaging box for storing or transporting the object M. Besides, the structure of the multistage cushioning air-filling packaging apparatus according to the present invention can significantly enhance the cushioning performance in all sides, so as to prevent the object M from being damaged by external impact or shock.

FIG. 32 is a sectional view of the air-filling packaging apparatus being inflated according to the above alternative mode of the above fifth preferred embodiment of the present invention. The non-inflated outer bag portion 10 b is formed by an extended part of monolayer film, such as air chamber film, valve film, and etc., and the inner bag portion 10 b is further affixedly connected in the outer bag portion 10 a through the transverse heat-sealing seam 41 J on the bottom side, such that it is not required to tuck the inner bag portion 10 b into the outer bag portion 10 a on the packaging site.

FIG. 33 is a perspective view illustrating the uninflated air-filling packaging apparatus being expanded in a plane manner according to another alternative mode of the above fifth preferred embodiment of the present invention. According to this embodiment, the choke seam 38 K is arranged at a suitable position of the main channel 151 K in order to make a plurality of the air-storing units 13 K on the top side uninflatable, which are utilized to form the inner bag portion 10 b.

FIG. 34 is a 3D perspective view of the air-filling packaging apparatus according to another alternative mode of the above fifth preferred embodiment of the present invention. The 3D heat-sealing seams 40 L of the air-filling packaging apparatus further comprises a stopping seam 44 L respectively formed on each of the two sides of the inner bag portion 10 b heat-sealedly connecting the front and back sides of the inner bag portion 10 b . Each stopping seam 44 L can be embodied as a heat-sealed seam inclinedly extended from one fringe of the two sides toward the center. Therefore, when the object is accommodated in the accommodating chamber formed by the inner bag portion 10 b again, it will be retained between the two stopping seams 44 L. Then, there will be reserved space between the two sides of the object and the inner surfaces of the right side wall and the left side wall, such that when the two sides of the 3D packaging bag formed by the air cushion body 10 L receive external shock or impact, the impact force will not be directly transferred to the two sides of the object. Hence, the side cushion performance of the air-filling packaging apparatus can be enhanced.

FIG. 35 illustrate a perspective view of the air-filling packaging apparatus according to another alternative mode of the above fifth preferred embodiment of the present invention, which is similar with the embodiment illustrated in FIG. 34 , wherein the differences include that the stopping seam 44 M can be embodied as a longitudinally extended sealing seam. Moreover, when the object is then accommodated in the accommodating chamber formed in the inner bag portion 10 b , it will be retained and limited between the two stopping seams 44 M. It is worth mentioning that the stopping seams 44 L and 44 M mentioned above can be continuous sealing seams or intermittent sealing seams.

FIG. 36-40 illustrate the air-filling packaging apparatus according to a sixth preferred embodiment of the present invention, which has an inflatable structure so as to be inflated and provide air cushioning function for various packaged contents, such as electronic products, food, medical products, chemical products, biological materials, plastics and ceramics, fast moving consumer goods, and etc. The air-filling packaging apparatus can be easily stored and transported in a non-inflated state before use, while it can then be inflated on site, which is convenient to use.

According to this preferred embodiment of the present invention, the air-filling packaging apparatus can be embodied as an air cushion substance which is filled with air for example. Nevertheless, person skilled in the art should be able to understand that it can also be filled with other gas based on the application and needs. According to this preferred embodiment, it can form a 3D packaging bag after being inflated, so as to provide air cushioning function for object.

According to this preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 N. Namely, either one of the air cushion body 10 N forms a 3D packaging bag or a plurality of the air cushion bodies 10 N form the 3D packaging bag through heat-sealing connecting, such as adhesive bonding, heat-sealing, and etc. The embodiment illustrated in FIGS. 36-40 is formed by one air cushion body 10 N. More specifically, referring to FIG. 71A , the air cushion body 10 N comprises at least two air chamber films 11 N and 12 N forming the 3D packaging bag comprising one or more interconnected air-storing units 13 N through a series of 2D heat-sealing seams 30 N and 3D heat-sealing seams 40 N, wherein each the air-storing unit 13 N forms a air storage chamber 14 N that is able to store gas therein.

Person skilled in the art should be able to understand that the 2D heat-sealing seams 30 N is for heat-sealing the multiple films into a 2D cushion material, as FIG. 36 illustrate. The 3D heat-sealing seams 40 N is additional heat-sealing on the above 2D cushion material to make the air-filling packaging apparatus into a 3D packaging device that has a 3D structure and can accommodate the object, as is illustrated in FIG. 36 . The 2D heat-sealing seams 30 N and the 3D heat-sealing seams 40 N can connect multiple layers of films together through adhesive bonding, heat-sealedly connect, and etc. Preferably, according to this embodiment, the 2D heat-sealing seams 30 N and the 3D heat-sealing seams 40 N are both formed through heat-sealing technology.

More specifically, the 2D heat-sealing seams 30 N comprise a plurality of dividing seams 31 N dividing the two air chamber films 11 N and 12 N into a plurality of the air-storing units 13 N. Preferably, each row of the dividing seams 31 N is formed by heat-sealing technology that heat-sealedly connects two layers of the air chamber films 11 N and 12 N so as to form a row of the dividing seam 31 N between two adjacent air-storing units 13 N. The dividing seam 31 N may be a continuous heat-sealed line so as to have a plurality of the air-storing units 13 N be independent to one another. It is understandable that the dividing seam 31 N on the top side and the bottom side can respectively become a top side boundary seam and a bottom side boundary seam of the to air cushion body 10 N, as FIG. 36 illustrates. The dividing seam 31 N may also be an intermittent heat-sealed line so as to have a plurality of the air-storing units 13 N be interconnected. The air-storing unit 13 N can be in various shape, such as linear, circular, polygon, irregular, and etc. Referring to FIGS. 36-40 , the air cushion body 10 N according to the present invention may comprise a plurality of air-storing pillars of the same size abreast arranged, while referring to FIG. 48 , the air cushion body according to the present invention may also comprise a plurality of air-storing pillars of different sizes abreast arranged. In addition, the arrangements of the large or small air-storing pillars can be diverse, such as in an alternate manner, having only small air-storing pillars regionally, and etc., while the present invention shall not be limited thereto.

According to this preferred embodiment, referring to FIG. 71A , the air-filling packaging apparatus further comprises an inflation valve 20 formed by at least two valve films 21 and 22 . The two valve films 21 and 22 of the inflation valve 20 and the air chamber films 11 N and 12 N are overlappedly arranged. Besides, an air inlet channel 23 is formed between the valve films 21 and 22 for inflating to the air storage chamber 14 N. It is understandable that the lengths of the valve films 21 and 22 are shorter than the lengths of the air chamber films 11 N and 12 N. When the air storage chamber 14 N is inflated via the air inlet channel 23 and the air pressure in the air storage chamber 14 N has attained the predetermined required value, the air pressure in the air storage chamber 14 N will act on the valve films 21 and 22 so as to attach the valve films 21 and 22 on one of the air chamber film, which closes the air inlet channel 23 and makes the inflation valve 20 serve as a one-way valve. When each air-storing unit 13 N has at least an air inlet channel 23 formed therein and each of the air-storing units 13 N is independent to one another, even if one of the air-storing units 13 N is damaged and leaks, the rest of the air-storing units 13 N will not be affected, but still serve as air cushions.

It is understandable that the air chamber films 11 N and 12 N of the air cushion body 10 N and the valve films 21 and 22 of the inflation valve 20 can respectively be made of various suitable membrane materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, composite film, and etc, wherein the present invention shall not be limited thereto, as long as suitable flexible films are utilized. It is worth mentioning that in order to enhance the one-way sealing function, the valve films 21 and 22 of the inflation valve 20 can also be self-adhesive films acquired by adding chemical composition to the above films.

The air cushion body 10 H further comprises a main channel unit 15 N connected with each of the air-storing units 13 N or, preferably, integrally extended from each of the air-storing units 13 N. More specifically, according to this preferred embodiment, the extending directions of the main channel unit 15 N and the air-storing unit 13 N are perpendicular to each other. For example, according to this embodiment, each the air-storing unit 13 N is extended along a longitudinal direction, while the main channel unit 15 N is extended along a transverse direction. The main channel unit 15 N forms a main channel 151 N that has an inflation inlet 152 N. When the inflation inlet 152 N has an inflation nozzle arranged thereat for conducting an inflation process, gas will enter the main channel 151 N from the inflation inlet 152 N along a transverse direction, and enter each the air-storing unit 13 N along a longitudinal direction. Then, when the air pressure of each the air storage chamber 14 N reaches a predetermined value, the valve films 21 and 22 of the inflation valve 20 will attached on one of the air chamber films 11 N and 12 N, so as to self-seal and prevent the inflated gas from reversing into the main channel 151 N.

It is worth mentioning that, it is understandable that the main channel unit 15 N can be formed by two layers of the air chamber films 11 N and 12 N, two layers of the valve films 21 and 22 , or either one layer of the air chamber films 11 N and 12 N and either one layer of the valve films 21 and 22 .

Referring to FIG. 37 , the 2D heat-sealing seams 30 N further comprise a continuously sealed edge sealing seam 32 N respectively on the left and right sides and a continuously sealed main channel sealing seam 33 N on the left side of the air cushion body 10 N, wherein the main channel 151 N is formed between the left edge sealing seam 32 N and the main channel sealing seam 33 N. It is understandable that the edge sealing seam 32 N is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealedly connect the two air chamber films 11 N and 12 N. The main channel sealing seam 33 N is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealedly connect the two air chamber films 11 N and 12 N and the two valve films 21 and 22 respectively, as FIG. 37 illustrated. For example, the main channel sealing seam 33 N on the up and down sides that was formed through a first heat-sealing technology respectively heat-sealedly connects the air chamber film 11 N and the valve film 21 at the position corresponding to the air inlet channel 23 , heat-sealedly connects the air chamber film 12 N and the valve film 22 , and integrally heat-sealedly connects multiple layers of films at the rest places, which also divides the air cushion body 10 N into the main channel unit 15 N and the air-storing unit 13 N.

Referring to FIG. 37 , each the air-storing unit 13 N comprises two spaced gas duct seams 34 N adjacent to the main channel 151 N and formed through heat-sealedly connecting the air chamber films 11 N and 12 N and the valve films 21 and 22 . The air inlet channel 23 formed by the valve films 21 and 22 are arranged between the two gas duct seams 34 N.

Referring to FIG. 71A , the valve films 21 and 22 are further heat-sealedly connected with the air chamber film 11 N through a plurality of connecting seams 35 N, such that when the air pressure in the air storage chamber 14 N attained a predetermined value, the air pressure will act on the valve films 21 and 22 and because of the arrangement of the connecting seams 35 N, the valve films will be pushed toward the air chamber film 11 N and eventually be attached on the air chamber film 11 N, so as to close the air inlet channel 23 . That is to say, the connecting seam 35 N heat-sealedly connects the two valve films 21 and 22 and the air chamber film 11 N. Besides, referring to FIG. 37 , the shape of each the connecting seam 35 N allows it to further prevent the air from backflow. In other words, when the air in the air storage chamber 14 N is going to flow back, it will be obstructed by the connecting seam 35 N and cannot return into the main channel 151 N easily.

In addition, when the 2D heat-sealing seams 30 N are being formed through heat-sealing, the air inlet channel 23 of the valve films 21 and 22 of the inflation valve 20 can be formed through the arrangement a heatproof barrier device. Then the heatproof barrier device can be removed after the heat-sealing process. According to this embodiment, referring to FIGS. 37 and 71A , a heatproof layer 24 is arranged between the valve films 21 and 22 of the inflation valve 20 and attached with the inner surface of one of the valve films 21 and 22 . The heatproof layer 24 can be embodied as thermostable inks and etc. As a result, when the main channel sealing seam 33 N is formed through heat-sealing, the two valve films 21 and 22 will not be heat-sealedly connected, such that the air inlet channel 23 can be connected with the main channel 151 N and the access thereof will not be closed due to the heat-sealing.

According to this preferred embodiment, the main channel 151 N is formed by the two air chamber films 11 N and 12 N, the heatproof layer 24 and the valve films 21 and 22 respectively have extending section extended into the main channel 151 N, and the 2D heat-sealing seams 30 N further comprises a joint seam 36 N longitudinally and spacingly arranged at the position corresponding to the extending section of the heatproof layer 24 . Because of the arrangement of the heatproof layer 24 , the joint seam 36 N respectively connects the two air chamber films 11 N and 12 N and the two valve films 21 and 22 , while the two valve films 21 and 22 are not heat-sealedly connected with each other. The arrangement of the joint seam 36 N allows adjacent valve films 21 and 22 and the correspondingly connected air chamber films 11 N and 12 N to be expanded together to open the corresponding air inlet channel 23 when air enters the main channel 151 N during the inflation of the air cushion body 10 N.

The 2D heat-sealing seams 30 N further comprise a plurality intermittent bending seams 37 N, wherein the inflated air cushion body 10 N is adaptable for bending along the bending seams 37 N, such that the air cushion body 10 N can form a plurality of side walls. More specifically, the bending seams 37 N divide each the air-storing unit 13 N into a plurality of sub-air-storing units 131 N. The bending seams can be arranged in the middle of the air-storing units 13 N and respectively form a connecting channel 132 N on the two sides thereof, such that the adjacent sub-air-storing units 131 N can be interconnected and communicated, as FIG. 37 illustrated. It is understandable that the bending seams 37 N can also be arranged on the two sides of the air-storing units 13 N, while the connecting channel 132 N is arranged in the middle of the air-storing units 13 N. Correspondingly, it is understandable that each the bending seams 37 N heat-sealedly connects two layers of the air chamber films 11 N and 12 N.

Further, referring to FIGS. 36-40 , according to a sixth preferred embodiment of the present invention, the bending seam 37 N comprises a intermittently heat-sealed first bending seam 371 N, such as the front bending seam 371 N, and an intermittently heat-sealed second bending seam 372 N, such as the rear bending seam 372 N, such that the air cushion body 10 N is adapted to form a front side wall 1011 N, a bottom connecting portion 1012 N, and a rear side wall 1013 N along the front bending seam 371 N and the rear bending seam 372 N, wherein the bottom connecting portion 1012 N is embodied as a sloping cushion portion 1012 N according to the present invention. Correspondingly, referring to FIGS. 36-39 , the 3D heat-sealing seams 40 N comprise a left 3D heat-sealing seam 46 N on the left side and a right 3D heat-sealing seam 47 N on the right side of the air cushion body 10 N, which heat-seal the left sides of the front side wall 1011 N and the rear side wall 1013 N, which, in other words, have the left side of the air cushion body 10 N sealed. The right 3D heat-sealing seam 47 N heat-seals the right sides of the front side wall 1011 N and the rear side wall 1013 N, so as to achieve the sealing of the right side of the air cushion body 10 N.

The above-mentioned front side wall 1011 N, rear side wall 1013 N, and sloping cushion portion 1012 N are bent and second heat-sealed through the 3D heat-sealing seams 40 N to form an accommodating chamber 108 N having an opening 107 N on the top side thereof. Namely, the air-storing units 13 N respectively form a ringlike air-storing pillar. That is, as FIG. 37 illustrate, the left part of the front bending seam 371 N is utilized to form the front side wall 1011 N, the sloping cushion portion 1012 N is formed between the front bending seam 371 N and the rear bending seam 372 N, and the rear side wall 1013 N is formed in the right side of the rear bending seam 372 N. It is understandable that the side walls 101 N and 103 N and the sloping cushion portion 1012 N are respectively formed by the sub-air-storing units 131 N integrally extended from the air-storing unit 13 N along the length direction thereof.

It is worth mentioning that because the lengths of the front side wall 1011 N and the rear side wall 1013 N are different, the connecting portion of the sloping cushion portion 1012 N will be in a sloping state. That is, the bottom connecting portion 1012 N and the rear side wall 1013 N will form a buffer gap 1002 N to thicken the cushion, so as to avoid the object from touching the bottom. In other words, the sloping cushion portion 1012 N is inclinedly extended between the front side wall 1011 N and the rear side wall 1013 N.

According to the embodiment illustrated in FIG. 36 , the length of the front side wall 1011 N is shorter than the length of the rear side wall 1013 N, such that the sloping cushion portion 1012 N can be inclinedly extended to form the buffer gap 1002 N between the rear side wall 1013 N and itself. Certainly, it is understandable that as an alternative mode, the length of the front side wall 1011 N may also be longer than the length of the rear side wall 1013 N. Moreover, it should be noted that though FIG. 37 illustrated the plane cushion substance formed through heat-sealing of the 2D heat-sealing seams 30 N, it also illustrated the position of the 3D heat-sealing seams 40 N, such that one may understand the forming process of the 3D packaging bag more easily.

It is worth mentioning that according to this preferred embodiment of the present invention, the left 3D heat-sealing seam 46 N and the right 3D heat-sealing seam 47 N respectively form a flank cushion portion 16 N on the two sides of the air-filling packaging apparatus. The 3D heat-sealing seam 46 N and 47 N are respectively arranged between the two adjacent air-storing units 13 N on the left and right sides, so as to respectively turn one or more of the air-storing units on the outermost left and right sides into the flank cushion portions 16 N. Referring to FIG. 38 , a left flank air-storing unit 134 N on the left side of the air cushion body 10 N bent through the bending seam 37 N and heat-sealed through the left 3D heat-sealing seam 46 N to form a left flank cushion portion 16 N that has a buffer space. A right flank air-storing unit 134 N on the right side of the air cushion body 10 N are bent through the bending seam 37 N and heat-sealed through the right heat-sealing seam 47 N to form a right flank cushion portion 16 N that has a buffer space. Hence, the flank cushion portions 16 N on the two sides of the air cushion body 10 N are to reinforce the side cushioning function. In other words, the flank cushion portion 16 N provides cushioning function on the side.

Referring to FIGS. 36-40 , according to this preferred embodiment, the air cushion body 10 N is adapted for accommodating the object. The object accommodated in the accommodating chamber can touch the front side wall 1011 N and the rear side wall 1013 N. The front side wall 1011 N and the rear side wall 1013 N provide cushioning function for the object. The flank cushion portion 16 N provides cushioning function for the object on the side. Nonetheless, the object does not directly contact the sloping cushion portion 1012 N. In other words, the object may not be extended into the buffer gap 1002 N, such that the sloping cushion portion 1012 N can provide cushioning function in a multistage manner for the object. That is, when there is external impact acting on the outside of the sloping cushion portion 1012 N, each air-storing unit 13 N of the sloping cushion portion 1012 N will provide a level of cushioning function or a first cushioning function. Further, the buffer gap 1002 N will provide another level of cushioning function or a second cushioning function to prevent the force that acts on the air-storing unit 13 N from being transferred to the object. In other words, when the air-storing units 13 N of the sloping cushion portion 1012 N are collided or impacted from the outside, the buffer gap 1002 N can provide a deformation space for the air-storing units 13 N, such that the external collision or impact force acted on the sloping cushion portion 1012 N will not be directly transferred to the object. That is to say, the sloping cushion portion thickens the cushion and provides cushioning function in a multistage manner, so as to prevent the object from touching the bottom.

It is worth mentioning that when the air cushion body 10 N is utilized to bear the object and is inflated, the inner surfaces of the front side wall 1011 N and the rear side wall 1013 N may or may not attach the outer surface of the object. For example, one may also add a packing bag to wrap the object. Preferably, according to this embodiment, the object is, for instance, a laptop M. The laptop M can be partially or fully put in the accommodating chamber 108 N. When part of the laptop M, or any side thereof, is put into the accommodating chamber 108 N, that side of the laptop M does not directly contact the sloping cushion portion 1012 N. In other words, the laptop M may not be extended into the buffer gaps 1002 N, such that the sloping cushion portion can thicken the cushion and provide better cushioning function for the laptop M.

In addition, referring to FIG. 40 , in order to retain the laptop M and prevent it from sliding during transportation, there is one of the air cushion bodies 10 N respectively arranged on the two sides of the laptop M. That is to say, the object M can also be packaged through coupling two of the air-filling packaging apparatuses. Namely, the present invention provides a packaging assembly, which comprises two of the air-filling packaging apparatuses, wherein two extremities of the object M are respectively accommodated in two accommodating chambers 108 N of the air-filling packaging apparatuses, wherein the entire package is put in other packing case or packaging box so as for storing or transporting the laptop M. That is, the laptop M has one of the buffer gap 1002 N on each of the two sides and does not have to reach or extend into the buffer gaps 1002 N, such that the two sloping cushion portions of the air cushion body 10 N thicken the cushion for the laptop M. Besides, the structure of the air-filling packaging apparatus according to the present invention can significantly enhance the cushioning performance in all sides, so as to prevent the object M from being damaged by external impact or shock.

Correspondingly, when the flank cushion portion 16 N receives external shock or impact, the external shock or impact will not directly pass through the flank cushion portion 16 N to the object, which means the flank air-storing unit 134 N of the flank cushion portion 16 N provides a cushion so as to achieve the cushioning function.

It is worth mentioning that the 3D heat-sealing seams 40 N can be continuous heat-sealed seams or intermittent heat-sealed seams. The left and right 3D heat-sealing seams 46 N and 47 N can be respectively located at the dividing seam 31 N on the sides of the air cushion body 10 N or be formed with the dividing seam 31 N through a first heat-sealing process at the same time. According to the above preferred embodiment, the left and right 3D heat-sealing seams 46 N and 47 N can respectively be an independent heat-sealed seam formed on the left or right edge of the air cushion body 10 N.

According to this embodiment of the present invention, referring to FIGS. 36-37 , the left 3D heat-sealing seam 46 N, for example, comprises a first heat-sealing section 461 N and a second heat-sealing section 462 N that are integrally heat-sealedly connected, equally long, and formed at the same time in the first heat-sealing process on the front and back sides of the air cushion body. Referring to FIG. 37 , the first heat-sealing section 461 N and the second heat-sealing section 462 N are spaced, rather than integrally formed. Moreover, the distance between the first heat-sealing section 461 N and the front bending seam 371 N is shorter than the distance between the second heat-sealing section 462 N and the rear bending seam 372 N, such that the sub-air-storing units 131 N between the front bending seam 371 N and the rear bending seam 372 N can form the sloping cushion portion 1012 N. That is to say, there is a first distance D 1 between the left 3D heat-sealing seam 46 N and the front bending seam 371 N in the front side, while there is a second distance D 2 between the left 3D heat-sealing seam 46 N and the rear bending seam 372 N in the back side, wherein the first distance D 1 is shorter than the second distance D 2 , such that the sub-air-storing units 131 N between the front bending seam 371 N and the rear bending seam 372 N are inclinedly extended. Similar, the right 3D heat-sealing seam 47 N has similar structure to the left 3D heat-sealing seam 46 N.

FIGS. 41-43 illustrate perspective views of the air-filling packaging apparatus according to a seventh preferred embodiment of the present invention, which is also an alternative mode of the above sixth preferred embodiment of the present invention. Similarly, according to this preferred embodiment, the object is, for instance, a laptop M.

The bending seams 37 N comprise two intermittently heat-sealed front bending seams 371 P and two intermittently heat-sealed rear bending seams 372 P, such that the air cushion body 10 P is adaptable for forming two front side walls 1011 P, two sloping cushion portions 1012 P, and a rear side wall 1013 P along the two front bending seams 371 P and the two rear bending seams 372 P. Correspondingly, referring to FIG. 42 , the 3D heat-sealing seams 40 P comprise a left 3D heat-sealing seam 46 P on the left side and a right 3D heat-sealing seam 47 P on the right side, which respectively heat-seal the left sides of the front side wall 1011 P and the rear side wall 1013 P, which, in other words, have the left side of the air cushion body 10 P sealed. The right 3D heat-sealing seam 47 P heat-seals the right sides of the front side wall 1011 P and the rear side wall 1013 P, so as to achieve the sealing of the right side of the air cushion body 10 P.

The above-mentioned front side wall 1011 P, the rear side wall 1013 P, and the sloping cushion portion 1012 P are bent and second heat-sealed through the 3D heat-sealing seams 40 P to form an accommodating chamber 108 P having an opening 107 P. That is, as FIG. 41 illustrated, the left or right parts of the two front bending seams 371 P form two the front side walls 1011 P respectively, each the sloping cushion portion 1012 P is formed between each the front bending seam 371 P and each the rear bending seam 372 P, and the rear side wall 1013 P is formed between the two rear bending seams 372 P. It is understandable that the side walls 101 A and 103 A and the sloping cushion portion 1012 P are respectively formed by the sub-air-storing units 131 P integrally extended from the air-storing unit 13 A along the length direction thereof.

It is worth mentioning that because the lengths of the two front side walls 1011 P and the rear side wall 1013 P are different, the connecting portions on the bottom side will be in a sloping state. That is, the two bottom connecting portions 1012 P and the rear side wall 1013 P will respectively form two buffer gaps 1002 P to thicken the cushion, so as to avoid the object from touching the bottom. In other words, two of the sloping cushion portions 1012 P are inclinedly extended between the two front side walls 1011 P and the rear side wall 1013 P.

According to the embodiment illustrated in FIG. 41 , the sum of the lengths of the two front side walls 1011 P is shorter than the length of the rear side wall 1013 P, the gap therebetween is for forming the opening 107 P for picking and placing object and making the two sloping cushion portions 1012 P be inclinedly extended to form the buffer gap 1002 P between the rear side wall 1013 P and themselves.

Moreover, it should be noted that FIG. 42 illustrates the 3D cushion material formed through heat-sealing of the 2D heat-sealing seams 30 P, it also illustrates the position of the 3D heat-sealing seams 40 P, such that one may understand the forming process of the 3D packaging bag more easily.

It is worth mentioning that according to this preferred embodiment of the present invention, the left 3D heat-sealing seam 46 P and the right 3D heat-sealing seam 47 P respectively form a flank cushion portion 16 P on the two sides of the air-filling packaging apparatus. Referring to FIG. 41 , a left flank air-storing unit 134 P on the left side of the air cushion body 10 P are bent through the bending seam 37 P and heat-sealed through the left heat-sealing seam 41 A to form a left flank cushion portion 16 P that has a buffer space. A right flank air-storing unit 134 P on the right side of the air cushion body 10 P are bent through the bending seam 37 P and heat-sealed through the right heat-sealing seam 47 P to form a right flank cushion portion 16 P that has a buffer space. Hence, the flank cushion portions 16 P on the two sides of the air cushion body 10 P are to reinforce the side cushioning function. In other words, the flank cushion portion 16 P provides cushioning function on the side.

Referring to FIGS. 41-43 , according to this preferred embodiment, the air cushion body 10 P is adapted for accommodating the object. The object accommodated in the accommodating chamber 108 P can touch the front side walls 1011 P and 101 A and the rear side wall 1013 P. The front side wall 1011 P and the rear side wall 1013 P provide cushioning function for the object. The flank cushion portion 16 P provides side cushioning function for the object. Nonetheless, the two sides of the object do not directly contact the two sloping cushion portions 1012 P. In other words, the object may not be extended into the buffer gap 1002 P, such that the sloping cushion portion 1012 P can provide cushioning function in a multistage manner for the object. That is, when there is external impact acting on the outside of the sloping cushion portion 1012 P, each air-storing unit 13 P of the sloping cushion portion 1012 P will provide a level of cushioning function or a first cushioning function. Further, the buffer gap 1002 P will provide another level of cushioning function or a second cushioning function to prevent the force that acts on the air-storing unit 13 P from being transferred to the object. In other words, when the air-storing units 13 P of the sloping cushion portion 1012 P are collided or impacted from the outside, the buffer gap 1002 P can provide a deformation space for the air-storing units 13 P, such that the external collision or impact force acted on the sloping cushion portion 1012 P will not be directly transferred to the object. That is to say, the sloping cushion portion thickens the cushion and provides cushioning function in a multistage manner, so as to prevent the object from touching the bottom.

It is worth mentioning that when the air cushion body 10 P is utilized to bear the object and is inflated, the inner surfaces of the front side wall 1011 P and the rear side wall 1013 P may or may not attach the outer surface of the object. For example, one may also add a packing bag to wrap the object. Preferably, according to this embodiment, the object is, for instance, a laptop M. The laptop M can be put in the accommodating chamber 108 P. The front side wall 1011 P and the rear side wall 1013 P provide cushioning function for the front and back sides of the laptop M, while the flank cushion portions 16 P provide cushioning function for the left and right sides of the laptop M. The rest two sides of the laptop M does not directly contact the two sloping cushion portions 1012 P. In other words, the laptop M may not be extended into the buffer gaps 1002 P, such that the sloping cushion portions can thicken the cushion and provide better cushioning function for the top and bottom sides of the laptop.

It is worth mentioning that the 3D heat-sealing seams 40 P can be continuous heat-sealed seams or intermittent heat-sealed seams. The heat-sealing seams 46 P and 47 P can be respectively located at the dividing seam 31 P on the sides of the air cushion body 10 P or be formed with the dividing seam 31 P through a first heat-sealing process at the same time. According to the above preferred embodiment, the heat-sealing seams 46 P and 47 P can respectively be an independent heat-sealed seam formed on the left or right edge of the air cushion body 10 P.

FIGS. 44-47 illustrate perspective views of the air-filling packaging apparatus according to an eighth preferred embodiment of the present invention, which is also an alternative mode of the above sixth preferred embodiment of the present invention and is formed by connecting head portion of the sixth preferred embodiment. Similarly, according to this preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 Q and an inflation valve 20 serving as a self-sealing one-way air inlet. It forms one or more interconnected air-storing units 13 Q through a series of 2D heat-sealing seams 30 Q and 3D heat-sealing seams 40 Q, wherein the air-storing units are circularly arranged to surroundingly form a ringlike accommodating chamber 108 Q, a bottom inclinedly arranged buffer gap 1002 Q, and a packaging chamber 1003 Q therein. When it is utilized, a ringlike object is suitable for being packaging in the ringlike accommodating chamber 108 Q. The packaging chamber 1003 Q may also be utilized for packaging the object.

According to this preferred embodiment of the present invention, the 3D heat-sealing seams 40 Q further comprises a longitudinal end sealing seam 43 Q heat-sealedly connecting the front side wall 1011 Q and the rear side wall 1013 Q along the longitudinal direction, which means the air cushion body 10 Q is circularly arranged and the head and tail thereof are connected. The head portions of the front side wall 1011 Q and the rear side wall 1013 Q are connected to respectively form an inner side wall 1014 Q and an outer side wall 1015 Q, so as to form a sloping cushion portion 1012 Q to provide cushion for the object. Thus, the air cushion body 10 Q is able to form an inflatable 3D packaging bag having the bottom ringlike reinforced sloping cushion portion 1012 Q through the transverse heat-sealing seams 46 Q and 47 Q and the end sealing seam 43 Q that heat-sealedly connect multiple layers of films. Besides, the object is suitable for being packaged in the packaging chamber 1003 Q. Besides, when the object is packaged in the packaging chamber 1003 Q, because the inner and outer side walls are overlapped, surrounded, and heat-sealed into the predetermined structure, the air-filling packaging apparatus can form a multilayer structure, so as to provide a reinforced cushioning function for the object. In addition, because the sloping cushion portion 1012 Q is sloped outside-in, it will decrease the inside diameter of the air-filling packaging apparatus, such that it becomes more suitable for holding the object stably.

More specifically, referring to FIGS. 46-47 , because the head and tail of the sloping cushion portion 1012 Q is connected through the end sealing seam 43 Q, it forms the bottom reinforced sloping cushion portion 1012 Q. The bottom reinforced sloping cushion portion 1012 Q forms the ringlike bottom inclinedly arranged buffer gap 1002 Q. The bottom inclinedly arranged buffer gap 1002 Q further thickens the cushion on the basis of the sixth preferred embodiment of the present invention.

It is understandable that, according to the preferred embodiment illustrated in FIGS. 44-47 , the air cushion body 10 Q is adapted for accommodating the object, wherein the object is accommodated in the accommodating chamber 108 Q. The sloping cushion portion 1012 Q forms a surrounding side wall. The surrounding side wall provides a cushioning function for the object. Because the surrounding side wall is formed by heat-sealedly connecting the front side wall 1011 Q and the rear side wall 1013 Q through the end sealing seam 43 Q as the above first embodiment and it respectively forms an outer side wall 1015 Q and an inner side wall 1014 Q in a circularly manner, when external impact acts on the surrounding side wall, the outer side wall 1015 Q, the inner side wall 1014 Q, and the buffer space between the outer side wall 1015 Q and the inner side wall 1014 Q can provide three levels of the cushioning functions for the object. Namely, the surrounding side wall provides a cushioning function for the object. Nonetheless, the object does not directly contact the bottom sloping cushion portion 1012 Q. In other words, the object may not be extended into the bottom inclinedly arranged buffer gap 1002 Q, such that the bottom sloping cushion portion 1012 Q can provide cushioning function in a multistage manner for the object. That is, when there is external impact acting on the outside of the bottom sloping cushion portion 1012 Q, each sub-air-storing unit 131 Q of the bottom sloping cushion portion 1012 Q will provide a level of cushioning function or a first cushioning function. Further, the inclinedly arranged buffer gap 1002 Q on the bottom will provide a deformation space for the air-storing unit, so as to provide another level of cushioning function or a second cushioning function to prevent the force that acts on the air-storing unit 13 Q from being transferred to the object. In other words, when the air-storing units 13 Q of the bottom sloping cushion portion 1012 Q are collided or impacted from the outside, the inclinedly arranged buffer gap 1002 Q can provide a deformation space for the air-storing units 13 Q, such that the external collision or impact force acted on the bottom sloping cushion portion 1012 Q will not be directly transferred to the object. That is to say, the sloping cushion portion thickens the cushion, so as to prevent the object from touching the bottom.

It is understandable that, referring to FIG. 46 , when the object M is packaged in the air-filling packaging apparatus, the bottom sloping cushion portion 1012 Q provides air cushioning function on the bottom side thereof, which thicken the cushion on the bottom side. In other words, this structural design strengthens its overall cushioning performance, especially on the bottom side.

Besides, according to this embodiment, the end sealing seam 43 Q of the 3D heat-sealing seams 40 Q can also be formed at the positions corresponding to the heat-sealing seams 46 Q and 47 Q. Alternatively, the heat-sealing seams 46 Q and 47 Q and the end sealing seam 43 Q can be formed at once in the first heat-sealing process, so as to connect the head and tail of the air cushion body 10 Q. Similarly, according to this embodiment, the end sealing seam 43 Q can be formed at each the edge sealing seam 32 Q of the flank cushion portion 16 Q.

FIG. 49-51 illustrate the air-filling packaging apparatus according to a ninth preferred embodiment of the present invention, which has an inflatable body structure, wherein the air-filling packaging apparatus has an accommodating portion and a subsidiary portion. After inflation, the accommodating portion will have an accommodating chamber for providing air cushioning function for the main body of various packaged contents, such as electronic products, food, medical products, chemical products, biological materials, plastics and ceramics, fast moving consumer goods, and etc. The air-filling packaging apparatus can be easily stored and transported in a non-inflated state before use, while it can be inflated on site, which is convenient to use. The subsidiary portion is utilized to provide further cushioning function for the object and is able to accommodate the accessory of the object, so as to avoid loss and damage caused by packaging the accessories and main body of the object having more accessories together. For instance, the air-filling packaging apparatus can be utilized for packaging a laptop, wherein the accommodating chamber of the accommodating portion is for packaging the laptop and is able to completely accommodate the laptop therein. The subsidiary portion can both be a side cushion component to provide cushioning function and accommodate the accessory of the laptop. Person skilled in the art should be able to understand that the above mentioned object could not be limited to the above mentioned examples. Instead, the air-filling packaging apparatus of the present invention may also be suitable for packaging other article(s).

It is worth mentioning that the medium for the air-filling packaging apparatus according to the present invention to provide cushioning function is fluid, such as gas, liquid, and etc.

According to the above ninth preferred embodiment, the air-filling packaging apparatus can be embodied as an air cushion substance which is filled with air for example. Certainly, person skilled in the art should be able to understand that it can be other gas according to the needs of the application. According to the above ninth preferred embodiment, it can form a 3D packaging bag after being inflated, so as to provide air cushioning function for object.

Specifically, according to the above ninth preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 R. Namely, one the air cushion body 10 R forms the 3D packaging bag through heat-sealing connecting, such as adhesive bonding, heat-sealing, and etc. The embodiment illustrated in FIGS. 49-51 is formed by one air cushion body 10 R. More specifically, referring to FIGS. 49, 50 , and 71 A, the air cushion body 10 R comprises at least two air chamber films 11 R and 12 R forming the 3D packaging bag comprising one or more interconnected air-storing units 13 R through a series of 2D heat-sealing seams 30 R and 3D heat-sealing seams 40 R, wherein each the air-storing unit 13 R forms a air storage chamber 14 R that is able to store gas therein.

Person skilled in the art should be able to understand that the 2D heat-sealing seams 30 R are for making multiple films form a 2D cushion material, as FIG. 50 illustrates, through heat-sealing. The 3D heat-sealing seams 40 R are additional heat-sealing on the above 2D cushion material to turn the air-filling packaging apparatus into a 3D packaging device that has a 3D structure and can accommodate the object, as FIG. 51 illustrates. The 2D heat-sealing seams 30 R and the 3D heat-sealing seams 40 R can connect multiple layers of films together through adhesive bonding, heat-sealedly connect, and etc. Preferably, according to the above ninth preferred embodiment, the 2D heat-sealing seams 30 R and the 3D heat-sealing seams 40 R are both formed through heat-sealing technology.

More specifically, referring to FIG. 50 , the 2D heat-sealing seams 30 R comprises a plurality of dividing seams 31 R dividing the two air chamber films 11 R and 12 R into a plurality of the air-storing units 13 R. Preferably, each row of the dividing seams 31 R is formed by heat-sealing technology that heat-sealedly connects two layers of the air chamber films 11 R and 12 R so as to form a row of the dividing seam 31 R between two adjacent air-storing units 13 R. The dividing seam 31 R may be a continuous heat-sealed line so as to have a plurality of the air-storing units 13 R be independent to one another. Therefore, when one of the air-storing units 13 R was damaged to leak, the rest of the air-storing units 13 R will not be affected. Certainly, it is worth mentioning that the air-storing units 13 R can also be interconnected, such that it requires only one inflation valve 20 to fill gas into all air-storing units 13 R. In other words, the air-filling packaging apparatus according to the present invention can form a plurality of the air-storing units 13 R through heat-sealing the first air chamber layer 11 and the second air chamber layer 12 .

It is understandable that the dividing seam 31 R on the top side and the bottom side can respectively become a top side boundary seam and a bottom side boundary seam of the air cushion body 10 R, as FIG. 49 illustrates. It is worth mentioning that the top side and bottom side mentioned here are relative concepts defined based on the relative positions to the air-filling packaging apparatus and the transverse. In other words, when the dividing seam 31 R of the air-filling packaging apparatus is perpendicular to the transverse, a top side and a bottom side will be defined. On the other hand, when the dividing seam 31 R of the air-filling packaging apparatus is parallel to the transverse, a left side and a right side will be defined. The dividing seam 31 R may also be an intermittent heat-sealed line so as to have a plurality of the air-storing units 13 R be interconnected. The air-storing unit 13 R may have various shapes, such as linear shape, circular shape, polygonal shape, irregular shape, and etc. Referring to FIGS. 49-51 , the air cushion body 10 R according to the present invention may comprise a plurality of air-storing pillars of the same size abreast arranged or a plurality of air-storing pillars of different sizes abreast arranged, which are, for example, all arranged longitudinally. In addition, the arrangements of the large or small air-storing pillars can be diverse, such as in an alternate manner, having only small air-storing pillars regionally, and etc., while the present invention shall not be limited thereto.

According to the above ninth preferred embodiment, FIGS. 71A-71C illustrated perspective views of the inflation valve 20 according to the present invention. Referring to FIG. 71A , the air-filling packaging apparatus further comprises an inflation valve 20 formed by at least two valve films 21 and 22 . The two valve films 21 and 22 of the inflation valve 20 and the air chamber films 11 R and 12 R are overlappedly arranged. Besides, an air inlet channel 23 is formed between the valve films 21 and 22 for inflating to the air storage chamber 14 R. It is understandable that the lengths of the valve films 21 and 22 are shorter than the lengths of the air chamber films 11 R and 12 R. When the air storage chamber 14 R is inflated via the air inlet channel 23 and the air pressure in the air storage chamber 14 R has attained the predetermined required value, the air pressure in the air storage chamber 14 R will act on the valve films 21 and 22 so as to attach the valve films 21 and 22 on one of the air chamber film, which closes the air inlet channel 23 and makes the inflation valve 20 serve as a one-way valve. When each air-storing unit 13 R has at least an air inlet channel 23 formed therein and each of the air-storing units 13 R is independent to one another, even if one of the air-storing units 13 R is damaged and leaks, the rest of the air-storing units 13 R will not be affected, but still serve as air cushions. Referring to FIG. 71B , the inflation valve 20 can further comprise an additional layer of valve film 25 between the two valve films 21 and 22 so as to enhance the sealing property. Referring to FIG. 71C , the inflation valve 20 can further comprise a layer of valve film 26 arranged between the air chamber film 12 and the valve film 22 , which is to be arranged on the outer side of the two valve films 21 and 22 , so as to prevent the junction between the valve film 22 and the air chamber film 12 R from being torn, such that the connection can be strengthened and stabilized. It is understandable that the specific structures of the inflation valve 20 are just examples, rather than limits to the scope of the present invention.

It is understandable that the air chamber films 11 R and 12 R of the air cushion body 10 R and the valve films 21 and 22 of the inflation valve 20 can respectively be made of various suitable membrane materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, and composite film, wherein the present invention shall not be limited thereto, as long as suitable flexible films are utilized. It is worth mentioning that in order to enhance the one-way sealing function, the valve films 21 and 22 of the inflation valve 20 can also be self-adhesive films acquired by adding chemical composition to the above films.

The air cushion body 10 H further comprises a main channel unit 15 R connected with each of the air-storing units 13 R or, preferably, integrally extended from each of the air-storing units 13 R. More specifically, according to an embodiment, the extending directions of the main channel unit 15 R and the air-storing unit 13 R are perpendicular to each other. For example, according to an embodiment, each the air-storing unit 13 R is extended along a longitudinal direction, while the main channel unit 15 R is extended along a transverse direction. The main channel unit 15 R forms a main channel 151 R that has an inflation inlet 152 R. When the inflation inlet 152 R has an inflation nozzle arranged thereat for conducting an inflation process, gas will enter the main channel 151 from the inflation inlet 152 along a transverse direction, and enter each the air-storing unit 13 R along a longitudinal direction. Then, when the air pressure of each the air storage chamber 14 R reaches a predetermined value, the valve films 21 and 22 of the inflation valve 20 will attached on one of the air chamber films 11 R and 12 R, so as to self-seal and prevent the inflated gas from reversing into the main channel 151 R.

It is understandable that the main channel unit 15 R can be formed by two layers of the air chamber films 11 R and 12 R, two layers of the valve films 21 and 22 , or either one layer of the air chamber films 11 R and 12 R and either one layer of the valve films 21 and 22 .

Referring to FIG. 50 , the 2D heat-sealing seams 30 R further comprise a continuously sealed edge sealing seam 32 R respectively on the left and right sides and a continuously sealed main channel sealing seam 33 R on the left side of the air cushion body 10 R, wherein the main channel 151 R is formed between the left edge sealing seam 32 R and the main channel sealing seam 33 R. It is understandable that the edge sealing seam 32 R is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealingly connect the two air chamber films 11 R and 12 R. The main channel sealing seam 33 R is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealingly connect the two air chamber films 11 R and 12 R and the two valve films 21 and 22 respectively, as the figure illustrated. For example, the main channel sealing seam 33 R on the up and down sides that was formed through a first heat-sealing technology respectively heat-sealedly connects the air chamber film 11 and the valve film 21 at the position corresponding to the air inlet channel 23 , heat-sealedly connects the air chamber film 12 and the valve film 22 , and integrally heat-sealedly connects multiple layers of films at the rest places, which also divides the air cushion body 10 R into the main channel unit 15 R and the air-storing unit 13 R.

Referring to FIG. 71A-71C , each the air-storing unit 13 R is arranged near the main channel 151 R, wherein the valve films 21 and 22 are further heat-sealedly connected with the air chamber film 11 through a plurality of connecting seams 35 R, such that when the air pressure in the air storage chamber 14 R attained a predetermined value, the air pressure will act on the valve films 21 and 22 and because of the arrangement of the connecting seams 35 R, the valve films will be pushed toward the air chamber film 11 and eventually be attached on the air chamber film 11 , so as to close the air inlet channel 23 . That is to say, the connecting seam 35 R heat-sealedly connects the two valve films 21 and 22 and the air chamber film 11 R. Besides, referring to FIG. 71A-71C , the shape of each the connecting seam 35 R allows it to further prevent the air from backflow. In other words, when the air in the air storage chamber 14 R is going to flow back, it will be obstructed by the connecting seam 35 R and cannot return into the main channel 151 R easily. In addition, when the 2D heat-sealing seams 30 R are being formed through heat-sealing, the air inlet channel 23 of the valve films 21 and 22 of the inflation valve 20 can be formed through the arrangement a heatproof barrier device. Then the heatproof barrier device can be removed after the heat-sealing process. According to an embodiment, referring to FIGS. 71A-71C , a heatproof layer 24 is arranged between the valve films 21 and 22 of the inflation valve 20 and connected with the main channel 151 R, so as to prevent the access from being closed by heat-sealing. The heatproof layer 24 can be embodied as thermostable inks and etc. According to an embodiment, the main channel 151 R is formed by the two air chamber films 11 R and 12 R, the heatproof layer 24 and the valve films 21 and 22 respectively have extending section extended into the main channel 151 R, and the 2D heat-sealing seams 30 R further comprise a joint seam 36 R longitudinally and spacingly arranged at the position corresponding to the extending section of the heatproof layer 24 . Because of the arrangement of the heatproof layer 24 , the joint seam 36 R respectively connects the two air chamber films 11 R and 12 R and the two valve films 21 and 22 , while the two valve films 21 and 22 are not heat-sealedly connected with each other. The arrangement of the joint seam 36 R allows adjacent valve films 21 and 22 and the correspondingly connected air chamber films 11 R and 12 R to be expanded together to open the corresponding air inlet channel 23 when air enters the main channel 151 R during the inflation of the air cushion body 10 R.

The 2D heat-sealing seams 30 R further comprise a plurality intermittent bending seams 37 R, wherein the inflated air cushion body 10 R is adaptable for bending along the bending seams 37 R, such that the air cushion body 10 R can form a plurality of side walls. More specifically, the bending seams 37 R divides each of the air-storing units into a plurality of sub-air-storing units 131 R. The bending seams 37 R can be arranged in the middle of the air-storing units 13 R and respectively form a connecting channel 132 R on the two sides thereof such that the adjacent sub-air-storing units 131 R can be interconnected and communicated, as FIG. 50 illustrated. It is understandable that the bending seams 37 R can also be arranged on the two sides of the air-storing units 13 R, while the connecting channel 132 R is arranged in the middle of the air-storing units 13 R. Correspondingly, it is understandable that each the bending seam 37 R heat-sealedly connects two layers of the air chamber films 11 R and 12 R.

Further, referring to FIGS. 49-51 , according to the above ninth preferred embodiment of the present invention, the bending seams 37 R comprise intermittently heat-sealed first bending seam 371 R, two second bending seam 372 R and third bending seam 373 R, fourth bending seam 374 R, fifth bending seam 375 R, and sixth bending seam 376 R. Each the bending seam divides each the air-storing unit 13 R into a plurality of sub-air-storing units 131 R, 1321 R, 1322 R, 1331 R, 1332 R, 134 R, 135 R, 136 R, 1371 R, 1372 R, 138 R, and 139 R. Because each the connecting channel 132 R can communicate adjacent air-storing units 13 R, each adjacent sub-air-storing units 131 R, 1321 R, 1322 R, 1331 R, 1332 R, 134 R, 135 R, 136 R, 1371 R, 1372 R, 138 R, and 139 R can all be communicated and interconnected. Hence, the air cushion body 10 R is adapted for being bent along the bending seams 37 R so as to form a plurality of side walls of the air-filling packaging apparatus. Specifically, the first bending seams 371 R, two second bending seams 372 R and third bending seam 373 R, a fourth bending seam 374 R, a fifth bending seam 375 R, and a sixth bending seam 376 R are bent to form a first side wall 1019 R, a second side wall 1039 R, a first connecting wall 10219 R, a second connecting wall 10229 R, a third connecting wall 1071 R, a first subsidiary side wall 1031 R, a second subsidiary side wall 1032 R, a third subsidiary side wall 1049 R, a fourth subsidiary side wall 1051 R, a fifth subsidiary side wall 1052 R, a sixth subsidiary side wall 1069 R, and an end wall 1072 R of the air-filling packaging apparatus. Correspondingly, referring to FIGS. 49-51 , the 3D heat-sealing seams 40 R comprise a left 3D heat-sealing seam 46 R on the left side of the air cushion body 10 R, a right 3D heat-sealing seam 47 R on the right side of the air cushion body 10 R, a first main accessory 3D heat-sealing seam 48 R, and a second main accessory 3D heat-sealing seam 49 R. The left 3D heat-sealing seam 46 R heat-seals the left sides of each first side wall 1019 R and each second side wall 1039 R. The right 3D heat-sealing seam 47 R heat-seals the right sides of each first side wall 1019 R and each second side wall 1039 R. The first main accessory 3D heat-sealing seam 48 R heat-seals the first connecting wall 10219 R and the second connecting wall 10229 R. The second main accessory 3D heat-sealing seam 49 R heat-seals the fourth subsidiary side wall 1051 R and the fifth subsidiary side wall 1052 R.

Hence, the air cushion body 10 R obtains a main accommodating portion 110 R, a subsidiary portion 120 R, and a lid portion 130 R through the above-mentioned plane heat-sealing and 3D heat-sealing. In other words, the first side wall 1019 R, the second side wall 1039 R, the first connecting wall 10219 R, and the second connecting wall 10229 R form the main accommodating portion 110 R, the first subsidiary side wall 1031 R, a second subsidiary side wall 1032 R, a third subsidiary side wall 1049 R form the subsidiary portion 120 R, and the fourth subsidiary side wall 1051 R, the fifth subsidiary side wall 1052 R, the sixth subsidiary side wall 1069 R, the third connecting wall 1071 R, and the end wall 1072 R form the lid portion 130 R all through a series of the 2D heat-sealing seams 30 R and the second heat-sealing of the 3D heat-sealing seams 40 R. In other words, the sub-air-storing units 131 R, 135 R, 1321 R, and 1322 R are arranged in a ringlike manner so as to form the main accommodating portion 110 R. The sub-air-storing units 1331 R, 1332 R, and 134 R are arranged in a ringlike manner so as to form the subsidiary portion 120 R. The sub-air-storing units 136 R, 1371 R, 1372 R, 138 R, and 139 R are arranged in a ringlike manner so as to form the lid portion 130 R.

The main accommodating portion 110 R has an opening 107 R and a main accommodating chamber 1001 R. The main accommodating portion 110 R is utilized for packaging the main body of the object. The main body of the object is put into the main accommodating chamber 1001 R through the opening 107 R. The first connecting wall 10219 R and the second connecting wall 10229 R can be utilized as the bottom portion of the main accommodating portion 110 R to provide cushioning function.

It is worth mentioning that because the main accommodating portion 110 R has the opening 107 R, when the object is put into the main accommodating chamber 1001 R, the lid portion 130 R will be connected to a side of the opening 107 R of the main accommodating portion 110 R in order to avoid the object from sliding and dropping from the main accommodating chamber 1001 R. The lid portion 130 R and the main accommodating portion 110 R are integrally heat-sealed, but they may also be separately made and connected according to other embodiment of the present invention. When the lid portion 130 R of the air-filling packaging apparatus is opened, the second side wall 1039 R and the third connecting wall 1071 R will be bent along the second main accessory 3D heat-sealing seam 49 R. When the object is put into the main accommodating chamber 1001 R, the lid portion 130 R will close the opening 107 R, while the third connecting wall 1071 R and the end wall 1072 R can serve as the top of the main accommodating portion 110 R. In addition, the lid portion 130 R has another buffer gap 1002 R to provide cushioning function.

It is worth mentioning that, according to this embodiment of the present invention, when the lid portion 130 R of the air-filling packaging apparatus is opened, the lid portion 130 R will have a springback force due to the influence of the air in the air cushion body 10 R. Thus, when the object is put in the main accommodating chamber 1001 R, the lid portion 130 R will automatically spring back to turn the air-filling packaging apparatus into the closed state. Because there is the springback force, the object will not slide out from the main accommodating chamber 1001 R easily. In other words, the object can have cushion protection in all directions.

The subsidiary portion 120 R serves to reinforce the side cushioning function provided by connecting the first connecting wall 10219 R and the second connecting wall 10229 R of the main accommodating portion 110 R. The subsidiary portion 120 R has a buffer gap 1002 R. The subsidiary portion 120 R is connected to a side of the main accommodating portion 110 R and formed by being integrally heat-sealed with the main accommodating portion 110 R. Nevertheless, they may also be separately made and connected according to other embodiment of the present invention. The subsidiary portion 120 R provides a second cushioning function for the object.

It is worth mentioning that when the lengths of the three subsidiary side walls 1031 R, 1032 R, and 1049 R of the subsidiary portion 120 R are increased or, in other words, when the space of the buffer gap 1002 R is enlarged, the subsidiary portion 120 R may also be considered an accessory accommodating portion for packaging the accessory of the object to avoid damage of the object caused by collision between the main body and the accessory of the object both being put in the main accommodating chamber 1001 R.

It is worth mentioning that the length of the first side wall 1019 R and the length of the second side wall 1039 R can be the same or different. Similarly, the length of the first connecting wall 10219 R and the length of the second connecting wall 10229 R can be the same or different. The length of the third connecting wall 1071 R and the length of the end wall 1072 R can be the same or different. The length of the fourth subsidiary side wall 1051 R and the length of the fifth subsidiary side wall 1052 R can be the same or different.

For instance, according to this preferred embodiment, preferably, the length of the first side wall 1019 R and the length of the second side wall 1039 R are the same; the length of the first connecting wall 10219 R and the length of the second connecting wall 10229 R are the same; the length of the third connecting wall 1071 R and the length of the end wall 1072 R are the same; and the length of the fourth subsidiary side wall 1051 R and the length of the fifth subsidiary side wall 1052 R are the same. Certainly, it is understandable that there could also be other reasonable alternative modes.

It is worth mentioning that, according to this preferred embodiment of the present invention, it is to reinforce the cushioning function in all directions. The left 3D heat-sealing seam 46 R and the right 3D heat-sealing seam 47 R respectively form a flank cushion portion on the two sides of the main accommodating portion 110 R of the air-filling packaging apparatus. The 3D heat-sealing seam 41 R and 42 R are respectively arranged between the two adjacent air-storing units 13 R on the left and right sides, so as to respectively turn one or more of the air-storing units on the outermost left and right sides into the flank cushion portions. For instance, the leftmost sub-air-storing units 131 R and 135 of the main accommodating portion 110 R of the air cushion body 10 R are bent through the bending seam 37 R and heat-sealed through the left 3D heat-sealing seam 46 R to form a left flank cushion portion that has a buffer gap. The rightmost sub-air-storing units 131 R and 135 R of the air cushion body 10 R are bent through the bending seam 37 R and heat-sealed through the right heat-sealing seam 42 R to form a right flank cushion portion that has a buffer gap. Hence, the flank cushion portions on the two sides of the main accommodating portion 110 R of the air cushion body 10 R are to reinforce the side cushioning function. In other words, the flank cushion portion provides cushioning function on the side of the main accommodating portion 110 R. When the flank cushion portion receives external shock or impact, the external shock or impact will not directly pass through the flank cushion portion to the object, which means the flank cushion portion provides a cushion so as to achieve the cushioning function.

Hence, according to the above ninth preferred embodiment of the present invention, the main accommodating portion 110 R of the air cushion body 10 R is adapted for accommodating the object. The object accommodated in the main accommodating chamber 1001 R can touch the first side wall 1019 R and the second side wall 1039 R. The first side wall 1019 R and the second side wall 1039 R provide cushioning function for the object. The first connecting wall 10219 R and the second connecting wall 10229 R provide cushioning function for the object on the bottom side and increase the cushion thickness between the subsidiary portion 120 R and the main accommodating portion 110 R. The flank cushion portions on the two sides of the main accommodating portion 110 provide side cushioning functions for the object. The buffer gap 1002 R of the lid portion 130 R provides deformation space. After the lid portion 130 R close the opening 107 R, the third connecting wall 1071 R and the end wall 1072 R can increase the cushion thickness between the lid portion 130 R and the main accommodating portion 110 R. The buffer gap 1002 of the subsidiary portion 120 R also enhances the cushioning function for the object on the bottom. It is worth mentioning that the subsidiary portion 120 R of the air cushion body 10 R may also be utilized for accommodating the accessory of the object. It avoids the main body and accessory of the object from contacting and colliding each other and provides accommodation and buffer gap for the accessory of the object, so as to prevent the object from being damaged when the accessory of the object is accommodated in the buffer gap 1002 . For example, when the object is a laptop, it can be put in the main accommodating chamber 1001 R and the lid portion 130 R and the subsidiary portion 120 R can provide cushioning function in all directions for the laptop. The accessory of the laptop, such as mouse and etc., can be put in the buffer gap 1002 , so as to damage of the laptop caused by collision between the laptop and the accessory both being put in the main accommodating chamber 1001 R. Hence, when the laptop M was impacted or shocked due to external factors, the air-filling packaging apparatus can provide cushion for the laptop M, such that the main body of the laptop M will not directly collide with the accessory, which reduce the risk of damage of the laptop M.

It is worth mentioning that when the air cushion body 10 R is utilized to bear the object and is inflated with gas, the inner surfaces of the first side wall 1019 R and the second side wall 1039 R may or may not attach the outer surface of the object. For example, one may also add a packing bag to wrap the object. It is worth mentioning that the 3D heat-sealing seams 40 R can be a continuous heat-sealed seam or an intermittent heat-sealed seam. The left and right 3D heat-sealing seams 41 R and 42 R can be respectively located at the dividing seam 31 R on the sides of the air cushion body 10 R or be formed with the dividing seam 31 R through a first heat-sealing process at the same time. According to the above preferred embodiment, the left and right 3D heat-sealing seams 41 R and 42 R can respectively be an independent heat-sealed seam formed on the left or right edge of the air cushion body 10 R.

It is worth mentioning that, according to other alternative modes of the present embodiment, the main accommodating portion 110 R can form a large diameter air chamber structure, small diameter air chamber structure, or combination of large and small diameter air chamber structures. Similarly, the subsidiary portion 120 R can form a large diameter air chamber structure, small diameter air chamber structure, or combination of large and small diameter air chamber structures. Corresponding, the lid portion 130 R can form a large diameter air chamber structure, small diameter air chamber structure, or combination of large and small diameter air chamber structures. The present invention shall not be limited thereto. Therefore, the main accommodating portion 110 R, the subsidiary portion 120 R, and the lid portion 130 R can form an arrangement having multilayer air chamber structure, where the each layer of the air chamber can provide a different level of cushioning function.

In other words, the sub-air-storing units 131 S, 135 S, 1321 S, and 1322 S are arranged in a ringlike manner so as to form the main accommodating portion 110 S. The sub-air-storing units 1331 S, 1332 S, and 1342 S are arranged in a ringlike manner so as to form the subsidiary portion 120 S. The sub-air-storing units 136 S, 1371 S, 1372 S, 138 S, and 139 S are arranged in a ringlike manner so as to form the lid portion 130 S.

Hence, according to the embodiment of the present invention, the object to be packaged is, for example, a laptop, wherein the main accommodating portion 110 S of the air cushion body 10 S is adapted for accommodating the laptop. The laptop is completely accommodated in the main accommodating chamber 1001 S and may touch the first side wall 1019 S and the second side wall 1039 S.

The flank cushion portions on the two sides of the main accommodating portion 110 S provide cushioning function for the laptop on the sides. The buffer gap 1002 S of the lid portion 130 S provides deformation space. After the lid portion 130 S close the opening 107 S, the third connecting wall 1071 S and the end wall 1072 S can increase the cushion thickness between the lid portion 130 S and the main accommodating portion 110 S. The buffer gap 1002 S of the subsidiary portion 120 S also enhances the cushioning function for the laptop on the bottom. It is worth mentioning that because the seventh subsidiary side wall 1081 S and the eighth subsidiary side wall 1082 S enlarge the space of the buffer gap 1002 S, the subsidiary portion 120 S of the air cushion body 10 S may also be suitable for accommodating the accessory of the laptop. It avoids the main body and accessory of the laptop from contacting and colliding each other and provides accommodation and buffer gap for the accessory of the laptop, so as to prevent the laptop from being damaged when the accessory of the laptop is accommodated in the buffer gap 1002 S.

According to another aspect of the present invention, FIGS. 54-56 illustrate a 11th preferred embodiment of the present invention. The differences between the above ninth preferred embodiment and the above 10th preferred embodiment include that the main accommodating chamber 1001 R is divided into two accommodating chambers, wherein one of the accommodating chambers is for accommodating the main body of the object, the other accommodating chamber is for accommodating the accessory of the object. In other words, the air-filling packaging apparatus according to the above third preferred embodiment of the present invention comprises a main accommodating portion 110 T, a subsidiary portion 120 T, and a lid portion 130 T after being bent, heat-sealed, and inflated. The main accommodating portion 110 T has a first main accommodating chamber 10011 T and a second main accommodating chamber 10012 T.

Specifically, referring to FIG. 56 , the bending seam 37 T comprises intermittently heat-sealed first bending seam 371 T, two second bending seam 372 T, third bending seam 373 T, fourth bending seam 374 T, fifth bending seam 375 T, and sixth bending seam 376 T. Each the bending seam divides each the air-storing unit 13 T into a plurality of sub-air-storing units 131 T, 1311 T, 1321 T, 1322 T, 1331 T, 1332 T, 134 T, 135 T, 1351 T, 136 T, 1371 T, 1372 T, 138 T, and 139 T. Because each the connecting channel 132 T can communicate adjacent air-storing units 13 T, each adjacent sub-air-storing units 131 T, 1311 T, 1321 T, 1322 T, 1331 T, 1332 T, 134 T, 135 T, 1351 T, 136 T, 1371 T, 1372 T, 138 T, and 139 T can all be communicated and interconnected.

The 3D heat-sealing seams 40 T comprise a left 3D heat-sealing seam 46 T on the left side of the air cushion body 10 T, a right 3D heat-sealing seam 47 T on the right side of the air cushion body 10 R, a first main accessory 3D heat-sealing seam 48 T, a second main accessory 3D heat-sealing seam 49 T, and a chamber 3D heat-sealing seam 450 T. According to this embodiment of the present invention, the first main accessory 3D heat-sealing seam 48 T and the second main accessory 3D heat-sealing seam 49 T are arranged parallelly to the bending seam 37 T, while the left 3D heat-sealing seam 46 T, the right 3D heat-sealing seam 47 T, and the chamber 3D heat-sealing seam 450 T are arranged parallelly to the dividing seams 31 T.

In other words, the air cushion body 10 T obtains the main accommodating portion 110 T, the subsidiary portion 120 T, and the lid portion 130 T through the above-mentioned plane heat-sealing and 3D heat-sealing. Specifically, the sub-air-storing units 131 T, 1311 T, 135 T, 1351 T, 1321 T, and 1322 T are arranged in a ringlike manner so as to form the main accommodating portion 110 T through a second heat-sealing of the 3D heat-sealing seams 40 T and a series of the 2D heat-sealing seams 30 T. The sub-air-storing units 1331 T, 1332 T, and 134 T are arranged in a ringlike manner so as to form the subsidiary portion 120 T. The sub-air-storing units 136 T, 1371 T, 1372 T, 138 T, and 139 T are arranged in a ringlike manner so as to form the lid portion 130 T.

It is worth mentioning that the heat-sealing of the chamber 3D heat-sealing seam 450 T divided the main accommodating chamber 1001 T of the main accommodating portion 110 T into a first accommodating portion 1101 T and a second accommodating portion 1102 T. Namely, the main accommodating portion 110 T has two accommodating chambers, which are respectively a first accommodating chamber 10011 T and a second accommodating chamber 10012 T. In other words, the sub-air-storing units 131 T, 135 T, 1321 T, and 1322 T are arranged in a ringlike manner so as to form the first accommodating portion 1101 T. The sub-air-storing units 1311 T and 1351 T are surroundingly arranged so as to form the second accommodating portion 1102 T.

According to this embodiment of the present invention, the first accommodating chamber 10011 T is spatially smaller than the second accommodating chamber 10012 T. Hence, the first accommodating chamber 10011 T can be utilized to package the accessory of the object, while the second accommodating chamber 10012 T can be utilized to package the main body of the object. For instance, if the object is a laptop, the second accommodating chamber 10012 T can be utilized to package the main body of the laptop, while the first accommodating chamber 10011 T can be utilized to package the accessory of the laptop, such as mouse, and power adapter. Thus, it can avoid damage of the laptop caused by collision between the main body and the accessory of the laptop during the transportation. Besides, it also provides cushion protection in all directions for the laptop. Of course, person skilled in the art should be able to understand that the sizes of the first accommodating chamber and the second accommodating chamber in this embodiment of the present invention shall not be limited thereto, but may change based on the object and the needs.

FIG. 57-60 illustrate the air-filling packaging apparatus according to a 12th preferred embodiment of the present invention, which has an inflatable body structure, wherein after the air-filling packaging apparatus was inflated, it will have a main accommodating chamber and an accessory chamber. The inflated main accommodating chamber is for providing air cushioning function for various packaged contents, such as electronic products, food, medical products, chemical products, biological materials, plastics and ceramics, fast moving consumer goods, and etc. The accessory chamber is for providing air cushioning function for the accessories of the object as well as providing a second cushioning function for the object. The air-filling packaging apparatus can be easily stored and transported in a non-inflated state before use, while it can then be inflated on site, which is convenient to use. For instance, the air-filling packaging apparatus can be utilized for packaging a laptop, wherein the main accommodating chamber is for packaging the main body of the laptop, while the accessory chamber is for packaging the accessory, such as power adapter, mouse, and etc., of the laptop. Because the air packaging bag has an air cushioning function, so as to be suitable for providing air cushioning effect for the object. Person skilled in the art should be able to understand that the above mentioned object could not be limited to the above mentioned examples. Instead, the air-filling packaging apparatus of the present invention may also be suitable for packaging other article(s).

It is worth mentioning that the medium for the air-filling packaging apparatus according to the present invention to provide cushioning function is fluid, such as gas and liquid.

According to this preferred embodiment, the air-filling packaging apparatus can be embodied as an air cushion substance which is filled with air for example. Certainly, person skilled in the art should be able to understand that it can be other gas according to the needs of the application. According to this preferred embodiment, it can form a 3D packaging bag after being inflated, so as to provide air cushioning function for object.

Specifically, according to the above preferred embodiment, the air-filling packaging apparatus comprises at least an air cushion body 10 U. Namely, either one of the air cushion body 10 U forms a 3D packaging bag or a plurality of the air cushion bodies 10 U form the 3D packaging bag through heat-sealing connecting, such as adhesive bonding, heat-sealing, and etc. The embodiment illustrated in FIGS. 57-60 is formed by one air cushion body 10 U. More specifically, referring to FIGS. 57, 59, and 71A , the air cushion body 10 U comprises at least two air chamber films 11 U and 12 U forming the 3D packaging bag comprising one or more interconnected air-storing units 13 U through a series of 2D heat-sealing seams 30 U and 3D heat-sealing seams 40 U, wherein each the air-storing unit 13 U forms a air storage chamber 14 U that is able to store gas therein.

Person skilled in the art should be able to understand that the 2D heat-sealing seams 30 U is for making the multiple films into a 2D cushion material, as FIG. 59 illustrates, through heat-sealing. The 3D heat-sealing seams 40 U is additional heat-sealing on the above 2D cushion material to turn the air-filling packaging apparatus into a 3D packaging device that has a 3D structure and can accommodate the object, as FIG. 59 illustrated. The 2D heat-sealing seams 30 U and the 3D heat-sealing seams 40 U can connect multiple layers of films together through adhesive bonding, heat-sealedly connect, and etc. Preferably, according to this preferred embodiment, the 2D heat-sealing seams 30 U and the 3D heat-sealing seams 40 U are both formed through heat-sealing technology.

More specifically, referring to FIG. 59 , the 2D heat-sealing seams 30 U comprises a plurality of dividing seams 31 U dividing the two air chamber films 11 U and 12 U into a plurality of the air-storing units 13 U. Preferably, each row of the dividing seams 31 U is formed by heat-sealing technology that heat-sealedly connects two layers of the air chamber films 11 U and 12 U so as to form a row of the dividing seam 31 U between two adjacent air-storing units 13 U. The dividing seam 31 U may be an continuous heat-sealed line so as to have a plurality of the air-storing units 13 U be independent to one another. Therefore, when one of the air-storing units 13 U was damaged to leak, the rest of the air-storing units 13 U will not be affected. Certainly, it is worth mentioning that the air-storing units 13 U can also be interconnected, such that it requires only one inflation valve 20 to fill gas into all air-storing units 13 U. In other words, the air-filling packaging apparatus according to the present invention can form a plurality of the air-storing units 13 U through heat-sealing the first air chamber layer 11 U and the second air chamber layer 12 U.

It is understandable that the dividing seam 31 U on the top side and the bottom side can respectively become a top side boundary seam and a bottom side boundary seam of the air cushion body 10 U, as FIG. 57 illustrated. It is worth mentioning that the top side and bottom side mentioned here are relative concepts defined based on the relative positions to the air-filling packaging apparatus and the transverse. In other words, when the dividing seam 31 U of the air-filling packaging apparatus is perpendicular to the transverse, a top side and a bottom side will be defined. On the other hand, when the dividing seam 31 U of the air-filling packaging apparatus is parallel to the transverse, a left side and a right side will be defined. The dividing seam 31 U may also be an intermittent heat-sealed line so as to have a plurality of the air-storing units 13 U be interconnected. The air-storing unit 13 U may have various shapes, such as linear shape, circular shape, polygonal shape, irregular shape, and etc. Referring to FIGS. 57-60 , the air cushion body 10 U according to the present invention may comprise a plurality of air-storing pillars of the same size abreast arranged or a plurality of air-storing pillars of different sizes abreast arranged. In addition, the arrangements of the large or small air-storing pillars can be diverse, such as in an alternate manner, having only small air-storing pillars regionally, and etc., while the present invention shall not be limited thereto.

According to the above preferred embodiment, FIGS. 71A-71C illustrated perspective views of the inflation valve 20 according to the present invention. Referring to FIG. 71A , the air-filling packaging apparatus further comprises an inflation valve 20 to formed by at least two valve films 21 and 22 . The two valve films 21 and 22 of the inflation valve 20 and the air chamber films 11 U and 12 U are overlappedly arranged. Besides, an air inlet channel 23 is formed between the valve films 21 and 22 for inflating to the air storage chamber 14 U. It is understandable that the lengths of the valve films 21 and 22 are shorter than the lengths of the air chamber films 11 U and 12 U. When the air storage chamber 14 U is inflated via the air inlet channel 23 and the air pressure in the air storage chamber 14 U has attained the predetermined required value, the air pressure in the air storage chamber 14 U will act on the valve films 21 and 22 so as to attach the valve films 21 and 22 on one of the air chamber film, which closes the air inlet channel 23 and makes the inflation valve 20 serve as a one-way valve. When each air-storing unit 13 U has at least an air inlet channel 23 formed therein and each of the air-storing units 13 U is independent to one another, even if one of the air-storing units 13 U is damaged and leaks, the rest of the air-storing units 13 U will not be affected, but still serve as air cushions. Referring to FIG. 71B , the inflation valve 20 can further comprise an additional layer of valve film 25 between the two valve films 21 and 22 so as to enhance the sealing property. Referring to FIG. 68 , the inflation valve 20 can further comprise a layer of valve film 26 arranged between the air chamber film 12 and the valve film 22 , which is to be arranged on the outer side of the two valve films 21 and 22 , so as to prevent the junction between the valve film 22 and the air chamber film 12 from being torn, such that the connection can be strengthened and stabilized. It is understandable that the specific structures of the inflation valve 20 are just examples, rather than limits to the scope of the present invention.

It is understandable that the air chamber films 11 U and 12 U of the air cushion body 10 U and the valve films 21 and 22 of the inflation valve 20 can respectively be made of various suitable membrane materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, composite film, and etc., wherein the present invention shall not be limited thereto, as long as suitable flexible films are utilized. It is worth mentioning that in order to enhance the one-way sealing function, the valve films 21 and 22 of the inflation valve 20 can also be self-adhesive films acquired by adding chemical composition to the above films.

The air cushion body 10 H further comprises a main channel unit 15 U connected with each of the air-storing units 13 U or, preferably, integrally extended from each of the air-storing units 13 U. More specifically, according to an embodiment, the extending directions of the main channel unit 15 U and the air-storing unit 13 U are perpendicular to each other. For example, according to an embodiment, each the air-storing unit 13 U is extended along a longitudinal direction, while the main channel unit 15 U is extended along a transverse direction. The main channel unit 15 U forms a main channel 151 U that has an inflation inlet 152 U. When the inflation inlet 152 U has an inflation nozzle arranged thereat for conducting an inflation process, gas will enter the main channel 151 U from the inflation inlet 152 U along a transverse direction, and enter each the air-storing unit 13 U along a longitudinal direction. Then, when the air pressure of each the air storage chamber 14 U reaches a predetermined value, the valve films 21 and 22 of the inflation valve 20 will attached on one of the air chamber films 11 U and 12 U, so as to self-seal and prevent the inflated gas from reversing into the main channel 151 U.

It is understandable that the main channel unit 15 U can be formed by two layers of the air chamber films 11 U and 12 U, two layers of the valve films 21 and 22 , or either one layer of the air chamber films 11 U and 12 U and either one layer of the valve films 21 and 22 .

Referring to FIG. 59 , the 2D heat-sealing seams 30 U further comprise a continuously sealed edge sealing seam 32 U respectively on the left and right sides and a continuously sealed main channel sealing seam 33 U on the left side of the air cushion body 10 U, wherein the main channel 151 U is formed between the left edge sealing seam 32 U and the main channel sealing seam 33 U. It is understandable that the edge sealing seam 32 U is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealedly connect the two air chamber films 11 U and 12 U. The main channel sealing seam 33 U is formed through heat-sealing technology, such as adhesive bonding, heat-sealing, and etc., to sealingly connect the two air chamber films 11 U and 12 U and the two valve films 21 and 22 respectively, as FIGS. 71A-71C illustrated. For example, the main channel sealing seam 33 U on the up and down sides that was formed through a first heat-sealing technology respectively heat-sealedly connects the air chamber film 11 and the valve film 21 at the position corresponding to the air inlet channel 23 , heat-sealedly connects the air chamber film 12 and the valve film 22 , and integrally heat-sealedly connects multiple layers of films at the rest places, which also divides the air cushion body 10 U into the main channel unit 15 U and the air-storing unit 13 U.

Referring to FIG. 71A-71C , each of the air-storing units 13 U is arranged near the main channel 151 U, wherein the valve films 21 and 22 are further heat-sealedly connected with the air chamber film 11 U through a plurality of connecting seams 35 U, such that when the air pressure in the air storage chamber 14 U attained a predetermined value, the air pressure will act on the valve films 21 and 22 and because of the arrangement of the connecting seams 35 U, the valve films will be pushed toward the air chamber film 11 U and eventually be attached on the air chamber film 11 U, so as to close the air inlet channel 23 . That is to say, the connecting seam 35 U heat-sealedly connects the two valve films 21 and 22 and the air chamber film 11 . Besides, referring to FIG. 71A-71C , the shape of each connecting seam 35 U allows it to further prevent the air from backflow. In other words, when the air in the air storage chamber 14 U is going to flow back, it will be obstructed by the connecting seam 35 U and cannot return into the main channel 151 U easily.
