The drive roller is rotatably mounted in the cabinet so that the outer surface of the roll rests directly on the outer surface of the drive roller.

Abstract: A flexible diaphragm for covering the discharge end of a cup dispenser that stores a plurality of cups in a nested stack. The diaphragm includes an inner continuous edge defining a central discharge opening through which the bottom of the outermost cup in the stack extends to be grasped and withdrawn from the stack. The inner continuous edge is configured in a polygonal shape to retain the stack of cups to be dispensed while permitting the outermost cup in the stack to be withdrawn from the stack. Preferably, the inner continuous edge is hexagonal in shape.

Abstract: A cup dispenser includes a housing for storing a plurality of cups nested in a stack. The cup dispenser has an annular collar surrounding the exterior of the housing. An annular retaining ring carries a cup holding member that is removably mounted on the collar such that the cup holding member is disposed over the discharge end of the housing to control removal of cups from the stack. The collar and housing have a locking arrangement which cooperates to permit relative movement of the collar and housing between a locked position and an unlocked position where the collar and housing can be separated. Portions of the collar and locking arrangement exposed to the interior of the housing preferably are substantially free of crevices or cavities which can trap bacteria.
