Abstract
A cup dispenser for accommodating conically shaped cups of different diameters includes a discharge unit having multiple diaphragms. An outer diaphragm has a series of inwardly extending circumferentially spaced flat fingers for gripping the outer surface of the cup. An inner diaphragm is similarly constructed. The circumferentially spaced flat fingers of the inner diaphragm differ in length one from the other, all of the inner diaphragm fingers being shorter than the outer diaphragm fingers. Preferably, the inner diaphragm is constructed to provide a series of fingers having a first length arranged alternately with a series of fingers having a second, shorter length. The outer diaphragm fingers resiliently grip the outermost cup to require positive pulling of the cup from the dispenser. The inner diaphragm fingers engage the larger end of the stacked cups as the outermost cup is pulled therefrom, to retain the stack within a tubular cup support.
