A cup dispenser includes a body defining a storage region adapted for receiving for an associated stack of cup-shaped articles. The body includes an open end that provides access to the storage region. Multiple fingers are connected to the body for restricting the open end of the body. An adjustment ring is connected to the body and is movable relative to the body. Movement of the adjustment ring relative to the body alters a position of each of the fingers relative to the body. The adjustment ring includes a plurality of adjustment slots and the fingers each include an adjustment stud located in one of the adjustment slots. When the adjustment ring is rotated, the adjustment slots act as cams and the adjustment studs act as cam followers such that the fingers are simultaneously and uniformly adjusted in terms of their radial position relative to the body wall.
