An apparatus for storing a supply of cup-shaped elements such as containers in a stacked, telescopically interfitted relationship comprises a tubular housing with a resilient diaphragm across the lower end. The diaphragm has a center opening through which the lowermost container extends. The diaphragm acts to retain the stack in the housing while permitting the lowermost container to be withdrawn. In one form, the diaphragm comprises a unitary piece of resilient, elastomeric material with the diaphragm having a resistance to elongation in directions circumferentially of the opening which increases progressively radially outwardly of the opening. In another form, the diaphragm includes integral fingers which extend radially inward of the opening. The fingers each decrease in width and thickness in the radial inward direction and may include a transverse rib on their inner surface to engage the lowermost container in the stack.
