ABSTRACT:
A dispensing valve particularly suited for use on the outlet nozzle of a membrane type beverage container comprises a first unitary component formed from a resilient resinous material and having a generally cylindrical main body with opposed axial ends. One of the ends includes an axially open circumferential groove adapted to sealingly receive and be retained on the outer end of the outlet nozzle. A circumferentially continuous seat lies radially inwardly of the groove. An opening extends axially through the body and has one end closed by a cylindrical closed end tubular portion. Assembled in the main body is an integral valve element and dispensing tube component comprising an imperforate valve disk having opposed faces and a diameter at least greater than the maximum diametric extent of the seat. A hollow dispensing tube is joined centrally to one face of the disk and extends axially thereof into the tubular portion of the main body. The dispensing tube has an inlet port formed at a location adjacent the disk and an outlet port adjacent the end of the tube remote from the disk. A radially extending flange is carried on the tube at a location intermediate the inlet and outlet ports. The flange is engaged by the body and biased in a direction to cause the disk to sealingly engage the seat.
