  • Oxygen-absorbing label
    Patent number: 6139935
    Abstract: An oxygen-absorbing label consisting of a base sheet, adhesive on the base sheet for securing the base sheet to an internal surface of a container, an oxygen-absorbing composition on the base sheet, and a cover sheet secured to the base sheet to confine the oxygen-absorbing composition therebetween, the cover sheet being fabricated of material which will permit oxygen to pass therethrough but will not stain due to the oxidation of the oxygen-absorbing composition or due to contact with materials in the container. A plurality of the foregoing labels are mounted on a web to be used with conventional labeling equipment.
    Type: Grant
    Filed: September 12, 1997
    Date of Patent: October 31, 2000
    Assignee: Multisorb Technologies, Inc.
    Inventors: John S. Cullen, Ronald C. Idol, Thomas H. Powers
  • Oxygen absorbing composition
    Patent number: 5746937
    Abstract: An oxygen absorbing composition having an effective amount of at least one oxygen absorbent contained in an emulsion. An oxygen absorbing product is produced by dispersing an oxygen absorbent in an emulsion to form an oxygen absorbing composition and transferring the oxygen absorbing composition onto a substrate.
    Type: Grant
    Filed: June 14, 1996
    Date of Patent: May 5, 1998
    Assignee: Multiform Desiccants, Inc.
    Inventors: George E. McKedy, Ronald C. Idol, Thomas H. Powers
  • Moisture-sensitive label
    Patent number: 5686161
    Abstract: An oxygen-absorbing label and a moisture-sensitive label. The oxygen-absorbing label consists of a base sheet, adhesive on the base sheet for securing the base sheet to an internal surface of a container, an oxygen-absorbing composition on the base sheet, and a permeable cover sheet secured to the base sheet to confine the oxygen-absorbing composition therebetween. The moisture-sensitive label is one wherein a moisture-sensitive material is used as part of the label instead of the oxygen-absorbing composition. The moisture-sensitive material may be a moisture adsorber such as silica gel or molecular sieve, or it may be a moisture supplier such as hydrogel. A plurality of the foregoing labels are mounted on a web to be used with conventional labeling equipment.

  • Oxygen absorber for low moisture products
    Patent number: 5207943
    Abstract: An oxygen-absorbing composition for absorbing oxygen from an enclosure, such as a package, containing a low-moisture product having an equilibrium relative humidity, or water activity, of between 30% and 90% including in relatively sufficient proportions for absorbing oxygen in the container, particles of iron, particles of a solid electrolyte material, and particles of hydrogel.
