Patent number: 7368153Abstract: The present invention relates to the non-invasive use of a luminescent compound to detect and measure concentrations of oxygen dissolved in a rigid container, especially a bottle, a tray, a carton, a lidstock associated with a tray, a stand up pouch, or a paperboard container. The measurement is made independent of the oxygen concentration of the surrounding atmosphere. The invention is especially useful as a quality assurance check to verify oxygen scavenger activation during the assembly of bottled products, and modified atmosphere and vacuum packages. The method according to the invention is faster and less wasteful than previous methods that rely on measuring oxygen concentration within the headspace of an assembled package.Type: GrantFiled: November 21, 2003Date of Patent: May 6, 2008Assignee: Cryovac, Inc.Inventors: Charles R. Barmore, Drew V. Speer, Thomas D. Kennedy, Marvin R. Havens

Patent number: 7364779Abstract: A plastic, easy-opening closure for a retortable container and a method for sealing are provided. The closure includes a plastic membrane having an outer layer of polypropylene, a first tie layer, an intermediate layer formed of EVOH, a second tie layer, an inner layer formed of polypropylene, and a peel-seal layer. The peel-seal layer can be formed of high density polyethylene or polypropylene with a contaminant dispersed therein so that the closure can be easily removed from the container for opening.Type: GrantFiled: September 2, 2003Date of Patent: April 29, 2008Assignee: Sonoco Development, Inc.Inventor: Srinivas Nomula

Patent number: 7332204Abstract: This invention relates to articles made of polyester, preferably polyethylene terephthalate (PET), having coated directly to at least one of the surfaces thereof one or more layers of thermoplastic material with good gas-barrier characteristics, and novel methods of making such articles. Preferably the barrier-coated articles take the form of preforms coated by at least one layer of barrier material and the containers blow-molded therefrom. Such barrier-coated containers are preferably of the type to hold beverages such as soft drinks, beer or juice. The preferred barrier materials have a lower permeability to oxygen and carbon dioxide than PET as well as key physical properties similar to PET. The materials and methods provide that the barrier layers have good adherence to PET, even during and after the blow molding process to form containers from preforms. Preferred barrier coating materials include poly(hydroxyamino ethers).Type: GrantFiled: January 24, 2003Date of Patent: February 19, 2008Assignee: Advanced Plastics Technologies Luxembourg S.A.Inventors: Gerald A. Hutchinson, Robert A. Lee
