Cup dispenser

A counter top dispenser adapted to dispense different diameter portion cups having a tapered sidewall, a bottom wall and an open top surrounded by a radially outwardly extending outer rim, said dispenser comprising:

• a housing located beneath the counter for storing a plurality of the cups in an inverted, nested stack and having a discharge end extending through an opening in the counter top;
• a mounting ring surrounding and connected to a portion of the discharge end of said housing extending through the counter top opening, said mounting ring adapted to rest on the counter top in the vicinity of the counter top opening;
• a flexible diaphragm covering the discharge end of said housing and including
• a web section including a central discharge opening through which the bottom of the outermost cup in the stack extends to be grasped and withdrawn from the stack, said opening having an inner periphery configured to retain a stack of the smallest cups to be dispensed in the housing while permitting the outermost cup in the stack to be withdrawn from the stack;
• and
• a plurality of circumferentially spaced apertures in said web section and spaced radially outwardly from the inner periphery of said central opening such that, when material between all circumferentially adjacent apertures is severed, the effective size of the inner periphery of said diaphragm discharge opening is enlarged sufficiently to permit the outermost cup in a stack of predetermined larger size cups to be withdrawn from the stack while retaining the stack in the housing;
• and
• means for holding said diaphragm in place over the discharge end of said housing.
