Abstract
A stop (20) for a dispensing valve (10) is adapted to be moveable between a first position abutting a valve surface (28) to seal an opening (30), and a second position spaced from the surface (28) to open the opening (30). The stop (20) has a base (52), and a sealing member (54) connected to the base (52) by a hinge member (60). The sealing member (54) has a sealing surface (66) at a distal end. The sealing member (54) extends away from the base (52) in a first molded position (MP). The sealing member (66) is foldable at the hinge member (60) to a second position (FP) wherein the sealing surface (66) faces generally towards the base (52). The method of making the valve stop (20) includes injection molding the stop (20) such that the sealing surface (66) is free of split-lines.
