ABSTRACT:
A pinch tube type valve adapted to be mounted to a liquid container receiver to accept an elongated flexible outlet tube protruding from a liquid container disposed in the receiver for selective control of liquid flow through the tube from the container. The tube is passed through a passageway in the valve body for selective engagement by a stem which is reciprocable into and out of closing engagement therewith. The passageway is enlarged adjacent the inlet end of the valve body to permit easy insertion of the liquid container outlet tube therethrough. An apertured tube retaining area is disposed adjacent the outlet end of the valve body passageway to receive and retain the tube in a desired position relative to the container receiver to facilitate ease of liquid dispensing operations. The stem may also include a tube engaging protrusion arrangement when the valve is contemplated for use in pressurized liquid systems.
