Patent number: 6854246Abstract: A flexible bag is positioned in a rigid container, such as a fifty-five gallon drum, and the bag is filled through its spout with flowable product, such as tomato paste. The bag is then expanded in the container to be substantially rigid and thereby reduce film movement and resultant flex cracking. A lid is sealed onto the container and a vacuum drawn from between the bag and the container, to, in turn, expand the bag. Gas volume needs to be present in the bag before the vacuum is applied so that the gas in the bag can expand from the vacuum on its outside. Once expanded, the container can be shipped.Type: GrantFiled: June 13, 2003Date of Patent: February 15, 2005Assignee: Scholle CorporationInventors: Chester Savage, Rocklin Verespej, Joseph C. Hsu, Robert Scholle

Publication number: 20040016672Abstract: A flexible bag is positioned in a rigid container, such as a fifty-five gallon drum, and the bag is filled through its spout with flowable product, such as tomato paste. The bag is then expanded in the container to be substantially rigid and thereby reduce film movement and resultant flex cracking. One way that the bag can be expanded, pursuant to this invention, is for a lid to be sealed onto the container and a vacuum drawn from between the bag and the container. Gas volume needs to be present in the bag before the vacuum is applied so that the gas in the bag can expand from the vacuum on its outside. Another way to expand the bag is, after filling the bag with the flowable product, to inject pressurized gas into the bag. For this embodiment, the container need not be vacuum sealable. For example, the container may be formed from a metal, plastic, cardboard and the like, and the container walls can be either solid or have openings.Type: ApplicationFiled: June 13, 2003Publication date: January 29, 2004Inventors: Chester Savage, Rocklin Verespej, Joseph C.

Patent number: 5209972Abstract: A multiple layer packaging film is based on three layers and wherein polyethylene terephthalate is one of the layers. All three layers are oriented. The three layers may be used as a stand-alone film, or may be combined with other layers to achieve additional beneficial properties. Desirably, the polyethylene terephthalate may be metallized, then laminated to a reverse printed layer of oriented polypropylene or polyester.Type: GrantFiled: November 3, 1988Date of Patent: May 11, 1993Inventors: Scott S.

Patent number: 4881649Abstract: The invention discloses a multiple layer packaging film, packages made therefrom and a method of opening the packages. The invention provides inseparable seal strength and in some cases hermetic seals, in combination with peelable ply separation opening for access to the contents of the package, while at the same time providing excellent barriers to transmission of oxygen and moisture. Certain embodiments provide for improved abuse resistance, excellent graphics, and other improvements. The method of opening the package depends on separating opposing ones of the package sidewalls, forcing the opening tear to be propagated partially through the film to a peelable layer interface, with subsequent ply separation along the interface to effect completion of opening of the package.Type: GrantFiled: April 17, 1989Date of Patent: November 21, 1989Assignee: American National Can CompanyInventors: Joseph C. Hsu, Anthony C. Guckenberger

Patent number: 4812319Abstract: An improved package and method of packaging, including an oil-containing product, includes a multiple layer packaging sheet material which has reduced sensitivity to cockling. The multiple layer sheet material includes a layer which is susceptible to being swelled when in contact with oil, giving a cockled appearance. With reference to the package structure, the sheet material also includes a layer which impedes penetration of oil, the impeding layer being between the oil-containing product and the layer which is susceptible to being swelled when in contact with oil. The impeding layer comprises polypropylene.Type: GrantFiled: July 6, 1987Date of Patent: March 14, 1989Assignee: American National Can CompanyInventors: Joseph C. Hsu, Robert A. Steen

Patent number: 4767651Abstract: Multiple layer films and containers. The films have a first layer of either nylon 6,6 or a combination of nylon 6,6 with nylon 6 wherein the melting point temperature of the combination is greater than the melting point temperature of the corresponding nylon 6. A second layer is comprised of linear low density polyethylene, and 0% to 40% low density polyethylene. A third adhesive layer is disposed between the first and second layers. The containers are susceptible of being sealed with included gas at low pressure, and subsequently boiled in water without rupture of the seals. The film is preferably coextruded from tubular die, thereby setting forth a new method for forming a mulitple layer film comprising a combination of linear low density polyethylene, optionally with up to 40% low density polyethylene, and nylon 6,6, optionally combined with nylon 6 in a composition having a melting point temperature greater than that of the corresponding nylon 6.Type: GrantFiled: July 27, 1987Date of Patent: August 30, 1988Assignee: American National Can CompanyInventors: John F. Starczewski, Joseph C. Hsu, Robert J. Blemberg, Kevin J. Curie, Jerry F. Jesse

Patent number: 4590106Abstract: A three layer heat shrinkable film is disclosed, along with preferred process for making it. The film comprises a first heat sealable layer of an ionomer, a second layer of a vinylidene chloride copolymer, and a third layer of a blend of an ionomer and an EVA copolymer. The EVA content is no greater than 20% of the blend by weight, and the vinyl acetate content is at least 4.5% of the blend by weight. In the preferred process, a three layer tape is coextruded and cooled, and reheated to 197.degree.-203.degree.

Patent number: 4501797Abstract: An unbalanced polymeric film has a plurality of adjacent molecularly oriented layers. The first, second, and third layers are molecularly oriented, and are, respectively (1) polypropylene, (2) anhydride modified polypropylene and (3) a barrier layer of either ethylene vinyl alcohol or nylon or a blend of ethylene vinyl alcohol and nylon. A fourth layer is optionally oriented and serves as a heat sealable layer having good adhesion to the barrier layer. In a more sophisticated structure, the fourth layer is oriented and serves an adhesive layer between the barrier layer and a fifth sealant layer. The fifth layer is then optionally oriented. A process for making the films comprises heating the exterior surfaces of the two surface layers to a temperature between 10.degree. and 100.degree. F. below the respective heat sealing temperature of each of the respective surface layers, stretching the so-heated film, annealing the stretched film, and cooling the annealed film.Type: GrantFiled: December 1, 1982Date of Patent: February 26, 1985Assignee: American Can CompanyInventors: Scott S.
