A wine cork display and aerating system is disclosed. The wine cork system includes a plug with a corresponding sleeve operable to form a fluid tight seal inside the neck of a bottle, a holder operable to secure a wine cork and a plurality of aeration holes in communication with the bottle's contents to allow the wine to breathe and to prevent contamination of the wine.

Systems and methods for preserving oxidizable substances such as liquids or foodstuffs are disclosed. These systems incorporate a sealing device and an oxygen scavenging chemical or agent coupleable to the system. The oxygen scavenging agent can remove the oxygen from the headspace of a container such as a bottle of wine without reducing the pressure in the headspace to the extent that the flavor of the wine is adversely affected.

A device for the preservation of degradable substances (e.g. degradable by oxidation) such as liquids or powders, especially edible substances, beverages (e.g. wine), or foods (e.g. coffee) as well as oils, tobacco, pharmaceuticals, colorants or paints in an opened container, e.g. a bottle, exposed to the oxygen of the air is provided herein. Aspects of the invention include an apparatus for removing oxygen from an opened container or bottle by coupling the container or bottle to a shell that contains an oxygen absorbent material such as reduced iron.

A medical rubber closure according to the present invention includes a disc-shaped flange portion and a leg portion formed to be continuous to a lower surface side of the flange portion, and a region at the lower surface side of the flange portion and the leg portion are made of a nitrile based rubber, a region at a top surface side of the flange portion is made of a butyl based rubber, and the leg portion is laminated with a coating layer made of a fluorine based resin film.

A beverage container includes a vessel and a stopper. The vessel includes a body with a neck portion. The body has an outer wall and an inner wall, and the neck portion defines an open end of the vessel body. The stopper selectively seals the open end of the vessel body in a closed, sealed position and selectively unseals of the open end of the vessel body in an open position. The stopper includes a body having an outer sidewall and a bottom wall. A seal is releasably connected to the body. The seal has a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the outer sidewall and the rim sealingly overlaps the bottom wall. The outer sidewall together with the seal define an air pathway for the flow of ambient air into an interior of the vessel.

A closure element for liquid containers, in particular bottles, includes a stopper engaging the opening of the liquid container (e.g., a neck of a bottle) and a cap (5) covering the edge of the neck opening, the stopper including an inlet channel passing therethrough and optionally an outlet channel, the inlet channel and optionally the outlet channel (42) are respectively provided with an inlet valve or outlet valve, which may be a pressure relief valve (21).

A plastic tube head for a product having a liquid to pasty consistency, comprising: a neck; a shoulder; and an insert forming a barrier having an outer edge which is covered in a continuous manner by an outer support made of plastic material forming the tube head, and an inner hole defining an inner edge. The tube head is characterized in that the inner edge of the insert is covered in a discontinuous manner by the plastic material forming the tube head, such that a portion of the face of the insert which is oriented towards the internal volume inside the tube and adjacent to the inner edge is covered by an inner support.

The present application is directed to cap assemblies and particularly, cap assembly for closing an opening in a vessel, the cap assembly including a stopper including an polymer body adapted to fit an opening of a vessel, the stopper also including a tubular portion which defines an internal passageway extending through the polymer body; and a rigid cap attached to and integral with the stopper, wherein the cap is adapted to engage the vessel and provide a sealing force between the stopper and the vessel.

By providing a synthetic closure which comprises at least one thermoplastic polymer and, as an additive, at least one fatty acid derivative, in particular a fatty acid ester or a fatty acid amide such as a stearamide, a synthetic closure is attained which achieved substantially enhanced properties. In particular, it has been found that the oxygen transfer rate of the closure is reduced substantially, thus reducing unwanted oxidation of wine. Furthermore, the use of a fatty acid derivative additive improves the performance characteristics of synthetic corks, such as extraction force, ovality control, diameter control and length control.
