Patent number: 6612545Abstract: An improved screw-on assembly for coupling line connectors with spouts has been invented. The invention can be used with bag-in-box packaging or with a variety of other applications requiring fluid coupling. In one embodiment, threading is accomplished by mating internal threads on a line connector with flexible tabs located on the spout. Deformation of the tabs during threading provides a restorative force that stabilizes the assembly during threading. Cooperation of the deformable tabs with structures near the end of the thread provides for self-locking of the assembly. In addition, the tabs are situated on a flange, providing compatibility of the present invention with prior art line connectors.Type: GrantFiled: April 12, 2000Date of Patent: September 2, 2003Assignee: David S. Smith Packaging LimitedInventors: Christopher C. Rutter, Lamar Spalding

Patent number: 6148874Abstract: A machine and method for filling bags with liquid through spouts attached to the bags, wherein a piston within a filling head that operates to control flow of the liquid from the filling head is also extended out of the filling head and into the spout, after the bag is filled, in order to push remaining material from the spout and through is bottom opening into the bag. The spout bottom opening is then closed, after which any remaining material adhering to the walls inside the spout and surfaces of the filling head are cleaned by forming a chamber between them through which a cleaning fluid is passed. This machine and method are particularly useful when filling bags with highly viscous and/or sticky liquids, such as thick food products. They avoid a result of having either to distribute messy bags of product with material remaining adhered to the outside of the spout and/or bag, or to first remove this material by an additional cleaning step.Type: GrantFiled: September 1, 1998Date of Patent: November 21, 2000Assignee: Packaging Systems, L.L.C.Inventors: Christopher C. Rutter, Stanley E. Hurd

Patent number: 6070622Abstract: A filling head apparatus for filling a container in sterile conditions. The filling head comprises a regulating valve displaceable in three positions: open position, closed position, and displacement position. The inner wall of the spout of the container is cleaned by a pushing cylinder of the regulating valve traveling from the closed position to the displacement position. In addition, the filling head can freely move in respect to a sterile filling chamber encompassing the filling tip of the filling head. Furthermore, the filling head of the present invention comprises a diversion path to minimize the "water hammer" effect.Type: GrantFiled: May 7, 1998Date of Patent: June 6, 2000Assignee: Packaging Systems, L.L.C.Inventor: Christopher C.

Patent number: 5983964Abstract: A method and apparatus for coupling with a spout to permit coupling of a valve sub-assembly housed in the apparatus with a slider valve housed in the spout. The apparatus includes a sleeve having at least two resilient finger members diverging from each other wherein each finger member has a flange engaging surface engageable with the flange portion of the spout. At least a portion of the sleeve is axially disposable about at least the flange portion of the spout, and the valve sub-assembly is slidable in the sleeve to couple with the slider valve in the spout when the sleeve is coupled to the spout. A collar is slidable over an outer surface of the sleeve for constricting the resilient finger members about the spout as the collar slides from an upper end of the sleeve and over the resilient finger members toward a lower end of the sleeve, and for releasing the constricted resilient finger members of the sleeve as the collar slides from the resilient finger members and toward the upper end of the sleeve.Type: GrantFiled: January 27, 1998Date of Patent: November 16, 1999Assignee: Packaging Systems, L.L.C.Inventors: James S. Zielinksi, William J. Olson, Christopher C. Rutter, Lamar Spalding

Patent number: 5901761Abstract: A spout fitment attached to a liquid filled bag, or other fluid container, of a type having a slidable dispensing valve member to receive a line connector for establishing a fluid path from an interior of the container, through a valve element in the line connector and into a service line attached to the line connector. Although the dispensing valve member is slid into the container when the line connector is inserted therein, the sliding motion does not form the container valve action. The container seal is established by a valve element within the slidable dispensing valve member that is resiliently biased to close an opening therein. The dispensing valve member thus need not be slid in the fitment when the line connector is removed from the dispensing valve member, thereby making it easier to remove and reinsert the line connector. Insertion of the line connector within the dispensing valve member causes their respective valve elements to engage each other to open and form the fluid flow path.Type: GrantFiled: October 1, 1997Date of Patent: May 11, 1999Assignee: Packaging Systems, L.L.C.Inventors: Christopher C. Rutter, Lamar Spalding

Patent number: 5810059Abstract: According to a preferred embodiment, a machine for filling containers, such flexible plastic bags, with fluid product, such a liquid food product, uses two container fill nozzles that each has a product supply system. While one of the nozzles is being used to fill containers that are being moved through the machine, the other nozzle and its product supply system is being cleaned. For the cleaning, at least one receptacle is provided to receive a nozzle being cleaned. Any product remaining in the delivery system and nozzle is flushed out through the receptacle in which the nozzle is inserted, and those portions cleaned. Fresh product is then loaded back into the delivery system and dispensed through the nozzle into the containers. This system and these operating techniques allow the product to be changed frequently without having to suffer a significant down time of the filling machine for cleaning.Type: GrantFiled: September 26, 1997Date of Patent: September 22, 1998Assignee: Packaging Systems, Inc.Inventors: Christopher C.

Patent number: 5147071Abstract: A collapsible bag for use in containing and dispensing a liquid, such as in a bag-in-box arrangement, and a method for making the bag. Prior to sealing together two bag walls to form the bag, a one-piece spout and evacuation strip unit is attached to the outside surface of one bag wall and one or more openings are provided through the bag wall in liquid communication with a plurality of liquid channels in the strip. The two bag walls are then sealed together to form the bag and the evacuation strip provides liquid passageways for the liquid in the bag to flow to the spout to achieve complete withdrawal of the liquid from the bag as the bag collapses.Type: GrantFiled: April 9, 1991Date of Patent: September 15, 1992Assignee: The Coca-Cola CompanyInventors: Christopher C.

Patent number: 5115626Abstract: A machine for automatically filling plastic bags with liquid or particulate material moves a continuous web of such bags through a number of serially positioned work stations. The bags are completely sealed when they enter the machine. As each bag passes through a slitting work station, a specially shaped opening is cut into the bag near an end of it which will become its top. When the bag proceeds to a filling work station, it is held vertically and a specially shaped fill nozzle is moved downward and rotated for entry into the bag through the slit opening. A valve is provided within the fill nozzle for controlling entry of the material into the bag. The valve and fill nozzle are cooperatively controlled by a single mechanism. The bags are transported through the various work stations by a positive toothed belt drive that preferably holds the bags flat until the filling station, wherein the belts are then moveable toward and away from each other in order to allow filling of the bag.Type: GrantFiled: October 2, 1990Date of Patent: May 26, 1992Assignee: Rapak, Inc.Inventors: Christopher C. Rutter, Robert A. Bilbrey, Bruce R. Koball
