ABSTRACT:
A cup dispenser includes a blow-molded plastic storage tube and a blow-molded plastic cup pushing member or follower positioned within the tube. The pushing member is optionally spring-biased toward an open first end of the tube away from a closed, second end of the tube. A resilient diaphragm is positioned over the open end of the cup storage tube or another suitable cup retainer is employed for releasably retaining a telescopically interfitted stack of cups in the storage tube. An annular collar is arranged coaxial with and fitted to the storage tube in the region of the open end. The cup storage tube and the cup pushing member are preferably blow-molded together in a single operation as a one-piece construction. The cup pushing member is separated from the cup storage tube for use.
