Abstract: In machines for vending liquids into cups, a cup guide and a cup stabilizing flapper are used to place the cup in position to receive the selected liquid. A flapper retractor apparatus is connected to the vending machine sliding door so that when a user opens the door to remove a filled cup, the cup flapper is simultaneously moved aside by the flapper retractor so that the filled cup may be more easily removed.
