Definitions

  • the present invention also provides a method for removing oxygen from a container by dispersing an oxygen absorbent in a liner, attaching the liner directly to an inner surface of a container cap, and placing the cap over an opening in the container such that the liner in the container cap seals the opening and absorbs oxygen within the container.
  • Fig. 1 is a cross-sectional side view of an oxygen absorbing container cap in accordance with an exemplary embodiment of the present invention
  • Fig. 5 is a top view of the embodiment shown in
  • the present invention provides an oxygen absorbing cap with an oxygen absorbent dispersed in a liner of the cap, the liner being directly attached to the inside surface of the cap. No cover layer is used over the liner.
  • the oxygen absorbing liner in the cap acts both as a sealant, providing a seal between the cap and the container, and as an oxygen absorber, removing oxygen from inside the container.
  • Liner 12 is disposed on the inner surface of cap 11.
  • Liner 12 in the illustrated embodiment includes a carrier resin with an oxygen absorbing material dispersed therein.
  • the oxygen absorbing salt may be sodium chloride or any other suitable food compatible salt including, but not " limited to, sodium sulfate, potassium chloride, ammonium chloride, ammonium sulfate, calcium chloride, sodium phosphate, calcium phosphate, and magnesium chloride.
  • suitable food compatible salt including, but not " limited to, sodium sulfate, potassium chloride, ammonium chloride, ammonium sulfate, calcium chloride, sodium phosphate, calcium phosphate, and magnesium chloride.
  • other non-food compatible salts may be used.
  • Cap 11 is attached to a container by first heating cap 11 until liner 12 softens. Cap 11 is then threaded onto the container, forming threads in liner 12 corresponding to grooves 13 in cylindrical portion 21 of cap 11. As shown in Fig. 3, cap 11 securely fits over the opening of container 15. Liner 12 seals cap 11 to container 15. Thus, liner 12 insures a tight fit between cap 11 and container 15 and facilitates the sealing function.
  • the embodiment illustrated in Fig. 4 also includes a central liner 31.
  • Central liner 31 is disposed on the inner surface of base portion 20.
  • Central liner 31 is centrally disposed and circular in the illustrated embodiment, but any shape or thickness may be used.
  • Central liner 31 contains an oxygen absorbent that absorbs oxygen within the container to which cap 11 is attached. The oxygen absorbent is dispersed in central liner 31 as discussed above.
  • Peripheral liner 30 and central liner 31 are both sprayed into cap 11 according to methods known in the art, and then heated to solidify.
  • Fig. 5 is a cop view of the embodiment illustrated in Fig. 4. This embodiment conserves both the carrier resin material used for the liners and the oxygen absorbents .
  • the following examples are presented to illustrate the present invention; they are not intended to limit it.
  • Example 2 * Weight of liner coated on inner surface of cap.
  • Polyvinylchloride plastisol in an amount of 8.40 grams was blended with 5.17 grams of 200 mesh iron containing 2% sodium chloride in an electric, high-speed mixer.
  • a sample of the resulting liner composition was coated on the inner surface of a container cap, which was placed in a 500cc mason jar containing lOOcc of oxygen.
  • a one-eighth-inch hole was drilled in the lid of the mason jar with a septum placed over the hole to prevent oxygen from leaking out of the container.
  • the container was left at room temperature at 100% relative humidity within the jar, and the amount of oxygen absorbed by the liner over time was measured. The procedure was repeated two times using different weight samples of liner within the cap. The results are tabulated below.
