Patent number: 4796788Abstract: Bag-in-box packaging of products which will not readily flow under gravity conditions for discharge. The bag is of special three-ply form to provide separate product and pressure chambers. Coupling fitments are connected independently to the respective chambers. When it is desired to dispense the product, the product fitment is exposed at a wall of the box along with the pressure fitment. A dispensing valve on the product fitment is opened and pressure is supplied and maintained in the pressure chamber to expand it and exert pressure through the baffle wall on the product in the product chamber to aid in the dispensing of the product therefrom. Before applying dispensing pressure, the box is disposed in an enveloping pressure-resisting unit. A novel method is provided for efficiently producing the special bag.Type: GrantFiled: August 26, 1987Date of Patent: January 10, 1989Assignee: Liqui-Box CorporationInventor: Curtis J. Bond

Patent number: 4445551Abstract: 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.Type: GrantFiled: November 9, 1981Date of Patent: May 1, 1984Inventors: Curtis J. Bond, John G. Ulm

Patent number: 4444340Abstract: 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.Type: GrantFiled: May 27, 1982Date of Patent: April 24, 1984Assignee: Liqui-Box CorporationInventors: Curtis J. Bond, John G. Ulm

Patent number: 4421146Abstract: 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.Type: GrantFiled: March 8, 1982Date of Patent: December 20, 1983Assignee: Liqui-Box CorporationInventors: Curtis J. Bond, John G. Ulm

Patent number: 4032106Abstract: A self-sealing dispensing valve for use on various containers. It is a simple two-piece device consisting of an outer housing having a dispensing outlet and an inner complemental valve member which ordinarily closes the outlet but which can be moved by finger pressure to open the outlet, and which will automatically return to its closed position when opening pressure is released. The housing has a flexible dome-shaped outer wall which embraces and is attached to a complemental dome-shaped rigid wall at the outer end of the valve member, which also has an axially inwardly extending flared sealing skirt. The skirt normally seats on the outlet, which extends radially through the correspondially tapered housing, but will be displaced axially inwardly to open the outlet, upon inward axial pressure on the outer dome-shaped flexible housing wall. Internal container pressure aids in the normal seating of the valve member.Type: GrantFiled: June 4, 1976Date of Patent: June 28, 1977Assignee: Corco, Inc.Inventors: Warren J. Schieser, John R.
