Abstract

A rolling device for supporting a roll of toilet tissue and for containing an air-treating substance. The device includes a pair of axially aligned body members forming an elongated cage for the air-treating substance, such body members being spread apart and adjusted in their relative axial positions by a spring which is compressible therebetween and made of a material which undergoes stress relaxation at ambient temperatures such that it readily takes a new set upon mounting. The body members each have an axial protuberance extending from an end surface, such end surfaces preferably being somewhat convex to help minimize the bearing surface of the device with the socket structures in which it is mounted. The air-treating material is preferably in beads free to tumble as the cage is rotated. The spring is preferably a polyolefinic material and preferably includes helical strands extending around the cage. The strands preferably have reduced cross-sections near their ends.
