A quick-disconnect service-line connector assembly for use in a beverage dispensing system or the like for connecting the service line to a single-service coupling and dispensing spout valve assembly on a flexible bag containing a liquid or semi-liquid product to be dispensed. It comprises a clamp which permits quick application to and removal from the spout of the single-service assembly and the clamp carries a guide structure for mounting a plug or nozzle body assembly for axial movement relative to the spout for insertion into the closed dispensing spout valve member carried therein for pushing it into opened position and simultaneously gripping it so that, as it is withdrawn, it moves the dispensing spout valve member again into closed position. In the nozzle body is a normally-closed flow control valve which is positively opened when the nozzle is inserted into the dispensing spout valve and which is automatically closed as it is withdrawn therefrom.
A service-line connector for connecting the service-line of a fluid dispensing system to a spout on a container or the like comprising means for removably mounting it on the spout, said connector including a nozzle body having a fluid passageway therethrough with a service-line connection and an inlet leading thereinto, a normally-closed valve for controlling flow into and out of said inlet, guide means extending from said mounting means for supporting the body for axial movement to insert it into and withdraw it from the spout and means for positively opening said valve as the nozzle body is inserted into the spout, said mounting means being of yoke form and being adapted to slip transversely onto the spout to interfit therewith to prevent axial movement of the mounting means relative to the spout in either direction during insertion of the nozzle body into or withdrawal of it from the spout.
A service-line connector and a cooperating coupling and valve assembly for a container which includes a spout having axially-spaced shoulders on its exterior and a dispensing valve member movable therein between normally-closed and opened positions, said service-line connector including means for removably mounting it on the spout, and a nozzle body having a fluid passageway therethrough with a service-line connection and an inlet leading thereinto, a normally-closed flow control valve for controlling flow through said inlet, in either direction, and guide means extending from said mounting means for supporting the nozzle body for axial movement to insert it into the spout to engage the dispensing spout valve member and move it into opened dispensing position, means carried by the dispensing spout valve member to positively open the normally-closed flow control valve in the nozzle body as it is inserted into the spout, and gripping means between the nozzle body and the dispensing spout valve member actuated by insertion of the body into the spout so that upon withdrawal of the body from the spout the dispensing spout valve member will be moved positively into closed position within the spout, said mounting means comprising a yoke adapted to slip radially onto the spout to interfit with said axially-spaced shoulders thereon to prevent axial movement of the mounting means relative to the spout in either direction during insertion of the nozzle body into or withdrawal of it from the spout.
