Abstract: A cup dispenser and process of using the cup dispenser are disclosed. The dispenser releases cups, one-by-one, from the bottom of a stack of cups seated one within the other and frictionally engaged to each other, the cups having a top rim. The apparatus comprises a cups carrier structure (10) adapted to be affixed to a generally vertical stationary support; and, an operator member (22) of generally planar configuration adapted to perform a reciprocating sliding movement within the cups carrier structure between extracted and inserted positions for releasing the cups one at a time. The operator member is the component that separates the bottom cup from the stack above and then dispenses it below. The operating member has two arm-like projections (30) and (28) generally parallel to each other and forming a hollow between them where the cups reside. Each arm-like projection comprises three sections in longitudinal succession relative to each other.
