ABSTRACT:
A double-layered rotary cup includes an outer receptacle in which an inner container is received. The container has an open top along which a circumferential lip carrying a seal ring in an underside thereof is formed to be slidably positioned on a top rim of the receptacle. The bottom of the receptacle forms a hole through which a bolt extends to engage an internally-threaded projection formed on the bottom of the container thereby forming a relatively rotatable configuration between the receptacle and the container. A spring biased positioner is arranged between the bottoms of the container and the receptacle for setting the relative angular position therebetween. Films on which patterns are printed are attached to an outside surface of the container and an inside surface of the receptacle and the film of the receptacle forms windows for exposing the patterns of the film of the container.
