Appl. No.:

09/874819

Inventors:

Daniel Bartholomew - Knightdale NC, US

International Classification:

B65D039/00
B29C047/00

US Classification:

215/355000, 264/045900, 264/148000

Abstract:

It has been discovered that the presence of an antioxidant in a closure or stopper, particularly in a synthetic closure or stopper, used to seal liquid products in a container causes excessive extraction forces to be required to remove the closure/stopper from the container. In particular, in sealing wine in a wine bottle, wherein the closure/stopper remains in the bottle for extended periods of time, the presence of the antioxidant causes increased extraction forces to be required. In accordance with the present invention, by reducing and controlling the amount of antioxidant employed in forming the closure/stopper, excessive extraction forces are controlled and remain at normal levels.

Abstract:

By securely affixing or bonding a multi-layer film to the terminating end of a closure/stopper, with the multi-layer film being constructed for promoting the transfer of all of the desirable gases, chemicals, and/or compounds while preventing the transfer of undesirable gases, chemicals, and/or compounds, a unique, closure or stopper having a sealed and/or barrier bearing terminating end is achieved. In this way, wine sealed in the wine bottle by the closure/stopper of the present invention is assured of possessing a long storage life, while also having the flavor, bouquet, taste, and quality desired for the wine fully maintained.
