ABSTRACT:
A cup dispenser is disclosed including a housing having an open end and a closed end defining a cup receiving cavity, a cup support reciprocally positioned within the cup receiving cavity for supporting at least one cup received in the cup receiving cavity and a spring for biasing the cup support towards the open end of the cup receiving cavity thereby projecting at least a portion of the cup from the housing. The cup dispenser further includes a guide for guiding the cup support within the housing with a guide including axially extending substantially diametrically opposed rails and a cup restraint for restraining outward movement of the cup within the cavity and a stop position adjacent the guide for stopping outward movement of the cup support. The stop includes at least one circumferentially extending contact surface which contacts a surface of the cup support in order to stop outward movement of the cup support. Additionally, the cup restraint includes at least one substantially radially inwardly extending detent positioned adjacent the open end of the housing as well as an auxiliary cup restraint positioned adjacent the first cup restraint for staging of the next cup to be dispensed. This auxiliary cup restraint prevents dispensing of more than one cup at a time by relieving the pressure of the total stack load and spring pressure on the cup to be dispensed. The auxiliary cup restraint includes at least one axially extending fin with the fin having an axial length which is less that the axial length of the diametrically opposed rails. The fins further include cup stacks stabilizers which stabilizes the stack of cups adjacent the open end of the housing. Further, an annular recess is formed in the housing extending about an outer circumference thereof and adjacent the open end of the housing.
