Abstract

Abstract This invention provides for a quick-disconnect coupling and valve assembly which consists of a single-service coupling and valve assembly and a connector for cooperating therewith. The single-service coupling and valve assembly is comprised of two main parts, namely, a spout fitment for a flexible bag and a valve member which slidably fits within the spout for axial movement. The valve member is provided with an outwardly-opening socket for receiving the connector and this socket has at least one dispensing outlet in the base thereof. In use, the valve member is normally in closed position with the outlet disposed within the spout axially-outwardly of an inner seal between the spout and valve member. A one-way stop arrangement permits axial inward movement of the valve member relative to the spout but prevents axial outward movement, the inward movement opening the valve by moving the outlet inwardly beyond the spout. This inward movement is accomplished by inserting the connector in the valve socket and pushing the valve member inwardly. At the same time, a gripper on the valve member is actuated to grip the connector so that subsequent axial-outward movement of the connector pulls the valve member axially-outwardly until it is stopped by the stop, so that the dispenser outlet is in thespout axially-outwardly of the inner seal. Continued outward movement of the connector, releases the gripper and permits withdrawal of the connector from the valve member socket.
