Abstract:
1. A vented valve assembly for attachment to a rigid container comprising: (a) a unitary tubular valve body of a generally cylindrical hollow form and having a liquid inlet end, a second end and a liquid outlet port, said liquid inlet end adapted for connection to a male spout on a wall of the rigid container, said liquid outlet port being exterior to the wall of the rigid container when the liquid inlet end is affixed to the spout, the valve body further including an air vent opening formed through a wall of the tubular valve body leading to a channel affixed to an inner wall of the tubular valve body, the channel having one open end; (b) a first valve member slidingly disposed in said channel and adapted to be moved between a blocking and an open position relative to said one open end of the channel; (c) a collapsible dome member secured to the valve body in covering relation to said second end of the tubular valve body and movable between a compressed and an expanded state; and (d) an elongated, generally rigid stem member having a first end attachable to the collapsible dome and a second end joined to a second valve member adapted to cooperate with the liquid inlet end of the tubular valve body for uncovering the liquid inlet end when the collapsible dome is in the compressed state, said stem member supporting a third valve member for cooperating with the liquid outlet port, and a spring-type valve displacement pin carried on the second valve member for holding the first valve member closed when the collapsible dome is in the expanded state.
