Abstract

A dispensing valve includes an annular ring of relatively rigid molded plastic construction and a flexible resilient valve element integrally molded with the ring. The ring and the valve element have at least one mechanical interlock to secure the valve element to the ring as the valve element is molded onto the ring. In some embodiments of the disclosure, the mechanical interlock includes openings in an inner periphery of the ring and pegs on the outer periphery of the valve element that are molded into the openings as the valve element is molded onto the ring.
