  • Patent number: 6709724
    Abstract: An oxygen scavenging composition of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. Also, a catalyzing agent is included in an amount sufficient to increase the rate of oxygen scavenging by the organic compound. The organic compound and catalyzing agent are preferably maintained in a dry state by freeze drying or microencapsulation until the organic compound is activated for oxygen scavenging by contact with water or water vapor.
    Type: Grant
    Filed: January 16, 1997
    Date of Patent: March 23, 2004
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: Fred N. Teumac, Bruce D. Zenner, Bert A. Ross, Larrie A. Deardurff, Mahmood R. Rassouli

  • Patent number: 5863964
    Abstract: A liner composition for a potable fluid container closure element which includes an inorganic sulfite such as sodium sulfite and/or a tocopherol compound such as dl-.alpha.-tocopherol (vitamin E) for preventing off-flavors due to the presence of aldehydes in the fluid. Also, a potable fluid container of a reservoir element for containing a potable fluid, the reservoir element having an opening, a closure element capable of being attached to the opening, and the liner composition associated with the closure element. Also, a method of improving the taste of a potable fluid such as bottled water by use of the container and one of the previously described liner compositions associated therewith. Also, an improved method for processing the composition into closure liners based upon the prevention of the development of off-flavor-causing substances therein.
