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.

A coupling and valve assembly comprising a spout having an annular tubular body open at its inner and outer ends, a valve member having an annular tubular body telescoped in the spout body and axially-slideable therein and having a closed inner end and an open outer end to provide an outwardly-opening socket for receiving a connector with the valve body having a dispenser outlet leading into the socket, a seal between the valve body and spout body axially inwardly of the dispenser outlet, one-way stop means between the valve body and spout body which prevents axial outward movement of the valve body in the spout body to keep the seal between the valve body and spout body but permits axial inward movement of the valve body relative to the spout body to move the dispenser outlet axially inwardly of the inner end of the spout body to permit dispensing through said outlet and said socket; a gripper arrangement at the outer end of the valve body and spout body for gripping the connector upon insertion into the socket and movement of the valve body axially inwardly into the spout body; said gripping arrangement comprising cam means at the outer end of said spout body and radially-movable yieldable gripping means at the outer end of the valve body normally engaging said cam means in a radially-extended position but movable positively radially inwardly by the cam means to grip the connector upon movement of the valve body axially inwardly of the spout body by the connector so as to move the outlet inwardly beyond the inner end of the spout body and to pull the valve body axially-outwardly to move the outlet into the spout body outwardly of said seal upon retraction of the connector from the spout body.
