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: 7141256Abstract: A package, which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes an impermeable tray supporting the product, a first film sealed to the tray for enclosing the product, a channel defined within the first film for exchanging gases into and out of the package, and a second impermeable film enclosing the first film, such that removal of the impermeable film provides for the exchange of gases into and out of the package. The channel for exchanging of gases may be perforations defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film, which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product. The channel for exchanging gases having a gas transmission rate of at least about 50,000 cc/m2/24 hrs./atm. at 73° F.Type: GrantFiled: January 17, 2003Date of Patent: November 28, 2006Assignee: Cryovac Inc.Inventors: David C.
