Document Type and Number:
Japanese Patent JP2001503712
Kind Code:
A
Abstract:
An article composed of a polymer material integrated with an oxygen scavenging agent is disclosed that is suitable for oxygen sensitive contents. Once affixed to the interior of a container, the novel article is capable of scavenging excess oxygen from the enclosed atmosphere of the container without substantially modifying the design of similar container. The article is composed of a polymer material integrated with an oxygen scavenging agent between 0.1 and 1.0 grams. One aspect of the article is a thin film which only surrounds the atmosphere of the container. In most container configurations, the article would be the neck portion of the container. Another aspect of the article is a thin film affixed to the bottom of a sealing cap for the container. The polymer material may be a polyolefin such as polyethylene. The oxygen scavenging agent may be selected from iron based compounds, organic compounds and biologically active compounds. More specifically, the iron based compounds may be selected from pure iron, iron containing organic compounds, FeOX, and FeXOZ(OH)T. The organic compounds used as oxygen scavenging agents may be selected from ascorbic acid, vitamin E, vitamin B and most other vitamins. The article is in direct contact with the gaseous contents of the atmosphere of the container. The present invention also discloses a method for fabricating an oxygen scavenging container.
