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 bas
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.

1. A stop for a dispensing valve, the dispensing valve having a surface defining an opening, the stop adapted to be moveable between a first position abutting the surface to seal the opening and a second position spaced from the surface to open the opening, the stop comprising:a base adapted to be connected to the valve; a sealing member being connected to the base by a hinge member, the sealing member having a frustoconical outer surface, the sealing member having a sealing surface at a distal end, the sealing member extending away from the base in a first position wherein the sealing surface faces generally away from the base, the sealing member being foldable at the hinge member to a second position wherein the sealing surface faces generally towards the base, a portion of the sealing member adapted to pass through the opening wherein the sealing surface is adapted to abut the valve surface; and, wherein the base has a peripheral surface, the base having a plurality of longitudinal ribs extending therefrom. 2. A stop for a dispensing valve, the dispensing valve having a surface defining an opening, the stop adapted to be moveable between a first position abutting the surface to seal the opening and a second position spaced from the surface to open the opening, the stop being formed in an injection-molding process, the stop comprising:a base adapted to be connected to the valve, the base having a peripheral surface, the base having a plurality of longitudinal ribs extending therefrom; a sealing member being connected to the base by a hinge member, the sealing member having a frustoconical outer surface, the sealing member having a sealing surface at a distal end generally adjacent the frustoconical outer surface, the sealing surface being substantially smooth across the entire surface and void of any split-line from the injection-molding process, the sealing member extending away from the base in a first molded position wherein the sealing surface faces generally away from the base, the sealing member being foldable at the hinge member to a second position wherein the sealing surface faces generally towards the base, a portion of the sealing member adapted to pass through the opening wherein the sealing surface is adapted to abut the valve surface. 3. A stop for a dispensing valve, the dispensing valve having a surface defining an opening, the stop adapted to be moveable between a first position abutting the surface to seal the opening and a second position spaced from the surface to open the opening, the stop comprising:a base adapted to be connected to the valve, wherein the base has a peripheral surface, the base having a plurality of longitudinal ribs extending therefrom; a sealing member being connected to the base by a hinge member, the sealing member having a frustoconical outer surface, the sealing member having a sealing surface at a distal end, the sealing member extending away from the base in a first position wherein the sealing surface faces generally away from the base, the sealing member being foldable at the hinge member to a second position wherein the sealing surface faces generally towards the base, a portion of the sealing member adapted to pass through the opening wherein the sealing surface is adapted to abut the valve surface, wherein the sealing surface is substantially smooth and even across its entire surface. 4. The stop of claim 3 wherein a portion of the sealing surface extends radially outwardly of the longitudinal ribs.5. The stop of claim 3 wherein the base has three longitudinal ribs extending therefrom.6. The stop of claim 3 wherein the sealing surface is generally adjacent the frustoconical outer surface.7. The stop of claim 3 wherein the sealing surface is void of a split line from an injection molding process.
