Publication number: 20140376832Abstract: The bag has a closure mechanism that simplifies and reduces the cost of the bag as compared to bags with conventional one-way valves. In one embodiment the valve is formed by two bond lines extending across the width of a plastic bag at different heights and terminating with one bond line above the other to leave an opening through which the bag is filled. Hydrophilic material expands to tension the opening and pinch it closed. In a second embodiment the one-way valve is formed on the angled edges of a two layer insert. This embodiment is functional with or without hydrophilic material. In both embodiments a supplemental closure is secured at the top of the bag to simplify opening the bag top and holding the bag while in use.Type: ApplicationFiled: June 19, 2013Publication date: December 25, 2014Inventors: Clarence A.

Patent number: 7967166Abstract: A storage system comprising: an evacuable and reclosable bag comprising a wall made of a flexible material and a one-way valve attached to said wall of said bag; a container having walls made of a material less flexible than the flexible material; and an attachment device that attaches the bag to the container such that at least a portion of the bag resides within the container. To use this storage system, compressible articles are placed inside the evacuable bag. Then the bag is hermetically sealed and evacuated. During evacuation, the shape of the compressible articles inside the bag conform to the shape of the container interior volume. In one embodiment, when the bag with compressed articles is removed from the container, its shape facilitates stacking. In another embodiment, the storage bag with compressed articles remains inside the container.Type: GrantFiled: November 16, 2007Date of Patent: June 28, 2011Assignee: Illinois Tool Works Inc.Inventors: Linh Pham, Martin Calvo, Dax Machovec

Patent number: 4637062Abstract: There is disclosed a bag assembly comprised of a tubularly-shaped bag preform formed of a plastic material defining a top closure portion and a bottom closure portion and provided with an adhesive layer peripherally-disposed about the tubularly-shaped bag preform proximate the top and bottom closure portions. The top closure portion and the bottom closure portion are subsequently formed with corner folds and side folds with the side folds being dimensioned whereby end portions of said side folds are spaced apart from one another upon subsequent folding agent about a fold line. A conduit member including a sleeve portion is mounted on one of the corner folds of the top closure portion by an adhesive layer portion disposed on the corner fold, and sheet members are thereupon mounted over the side and corner folds by adhesive layer portions thereon. After folding of the side fold members about the fold lines, top and bottom closure sheet members are mounted on the top and bottom closure portions.Type: GrantFiled: December 21, 1984Date of Patent: January 13, 1987Assignee: Bischof und Klein GmbH & Co.Inventor: Josef Poppe

Patent number: 4524458Abstract: Flexible plastic bags used for the bulk storage and dispensing of fluids are often blocked from dispensing all the contents and/or entrap part of the contents in folds of the plastic as they shrink during dispensing. The invention is for a tongue or dip tube that is attached to the inner wall of the plastic bag near the location of the dispensing aperture. The tongue is formed of a laminate of two dissimilar materials, one non-hygroscopic and the other being hygroscopic, so that upon introduction of moisture into the bag, the hygroscopic layer will expand and the normally flat tongue will curl to form a thick tube that both prevents collapse of the bag and prevents closure of the dispensing aperture by the opposite wall of the bag.Type: GrantFiled: November 25, 1983Date of Patent: June 18, 1985Inventors: Robert G. Pongrass, Christopher C. Rutter
