ABSTRACT:
Dispensing valves particularly intended for use on bag-in-the-box type beverage containers comprise a molded one piece structure formed of a resinous plastic material. The structure includes a body defining a fluid passageway having an inlet end and an outlet end. The body also includes a first wall member having an orifice through which the outlet end of the fluid passageway opens. The first wall member defines a first surface extending laterally outwardly of the orifice. A second wall member is molded integrally with the first wall member from a resilient material capable of undergoing significant elastic deformation. The second wall member sealingly overlies the orifice and is joined to the first wall at locations laterally outwardly of the orifice throughout a major circumferential extent. Operating device is provided for selectively deflecting the second wall member away from the orifice to permit flow through the orifice and between the first and second wall members.
