Abstract: A system for supplying liquid in large bottles from a point where they are filled to a dispenser having a reservoir for receiving the liquid. The bottles each have a neck which carries a cap unit for closing the spout thereof. Each cap unit has an outlet valve that is normally closed. The reservoir has means for supporting another normally closed inlet valve in a neck-receiving socket. When the neck is slipped into the socket the outlet valve of the cap unit is opened and substantially simultaneously the inlet valve for the reservoir is opened thus allowing flow of water from the bottle into the reservoir. When the bottle is removed from the reservoir as the cap unit is withdrawn from the neck-receiving socket, the outlet valve in the bottle neck cap unit is positively closed and the inlet valve of the reservoir automatically closes.

Abstract: A tear-off tab structure applicable to a self-closing dispensing valve structure of the toggle type mounted on a spout in which passage to the outlet is normally-closed by an axially inwardly-extending flexible wall structure that can be flexed by a toggle lever carried thereby to complete a discharge passage to the outlet. The tear-off tab structure substantially covers the outlet and to give access to the spout through the outlet the tab structure must be disturbed thereby giving evidence of tampering.

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.

Abstract: A removeable and replaceable self-sealing valve formed of resiliently flexible plastic which has inner and outer concentric walls spaced to provide an axially inwardly-opening socket for receiving the outer end of a semi-rigid plastic spout carried by a flexible plastic bag. The spout has one or more inner anular sealing ribs formed therein at a location spaced axially-inwardly from its lip and the inner wall normally resiliently engages this seal. A toggle lever is connected to the inner wall to flex it so that a portion thereof is flexed away from the sealing rib to open a dispensing passage to an outlet in the outer wall beyond the spout lip. A removable seal retainer insert holds the inner wall in sealed position until the valve is to be used.

Abstract: 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.
