OXIDATION SUPPRESSING STOPPER FOR WINE

摘要

A stopper and method for its use for selectively retaining a liquid, such as wine, within a bottle and for minimizing oxidation of the bottle's contents. The stopper includes a head portion sized to reside external to the bottle opening and a neck portion sized to fit and be selectively retained within the neck of the bottle. The stopper further has an inert gas entry port for receiving a source of pressurized inert gas and for introducing the inert gas proximate the meniscus of the liquid in the bottle and a gas venting port for discharging gas from the bottle upon the introduction of inert gas thereto. The stopper is provided with a plurality of seals substantially preventing liquid from passing through the stopper when the neck portion is seated within the bottle opening.
