Abstract
A crown system includes a crown having a top surface and a bottom surface and a liner having a top surface that contacts a bottom surface of the crown. The liner is configured to absorb oxygen in a headspace and includes at least about 2.2 micromoles of sodium sulfite per cubic millimeter in a volume of the liner to a depth of about 0.003 millimeter from a bottom surface of the liner.
Claims23
A crown system, comprising:
- a crown having a top surface and a bottom surface;
- a liner having a top surface and a bottom surface, wherein the top surface of the liner contacts the bottom surface of the crown;
- and
- wherein the liner comprises at least about 2.2 micromoles of sodium sulfite per cubic millimeter in a volume of the liner to a depth of about 0.003 millimeter from a bottom surface of the liner.
A liner, comprising:
- a base formula comprising PVC, a plasticizer, a stabilizer and a blowing agent;
- and
- at least six weight percent sodium sulfite and less than eighteen weight percent sodium sulfite.
A method of manufacturing a crown system, comprising:
- creating a crown comprising a top surface and a bottom surface;
- forming a liner that comprises an oxygen scavenger, wherein a top surface of the liner contacts the bottom surface of the crown;
- and
- printing on a bottom surface of the liner with a pigment-based ink.
A method of pasteurizing a container including a crown, comprising:
- providing a container including a crown and a liner and containing a malt beverage, wherein the liner contains at least about 2.2 micromoles of sodium sulfite per cubic millimeter in a volume of the liner to a depth of about 0.003 millimeter from a bottom surface of the liner, wherein the container has an original total package oxygen of less than about 1000 ppb oxygen prior to pasteurization;
- and
- pasteurizing the container.
A container closing system, comprising:
- a container closure mechanism having a top surface and a bottom surface;
- a liner having a top surface and a bottom surface, wherein the top surface of the liner contacts the bottom surface of the container closure mechanism;
- and
- wherein the liner comprises at least about 2.2 micromoles of sodium sulfite per cubic millimeter in a volume of the liner to a depth of about 0.003 millimeter from a bottom surface of the liner.
