COUPLING AND VALVE ASSEMBLY FOR A LIQUID DISPENSER

摘要

A coupling and valve assembly which permits a connector member (70) to be used to open and close the valve assembly with only one hand and which provides safeguards against accidental release of liquid therethrough. The coupling valve assembly comprises a spout (21) and a valve member slideable (22) within the spout, these two parts being so shaped as to provide inner and outer seals therebetween on either side of a dispenser outlet and a one-way stop (40) which prevents excessive outward movement of the dispenser outlet but permits the dispenser outlet to move inwardly to an open position. The valve member is normally moved to its open position by pushing a connector member (70) into the valve member; if desired, this connector member (70) can have a second, spring-biased valve, (84) which is opened by a projection (22a) on the valve member.
