BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to a plug for capping an open wine bottle to preserve its contents for later use.
2. Description of the Prior Art
It has long been a problem to preserve unused wine that remains in a bottle that has already been opened. It is well know that wine corks, which are placed onto wines when they are freshly bottled, create a virtual vacuum chamber, and that glass from which the bottle is constructed is impermeable to air for centuries and thus a good cork will keep air exchange to a minimum for an extended period. However, when the cork is removed, exposure of wine to air causes it to age rapidly, oxidizing and losing freshness. Thus, recapping wine bottles to prevent unnecessary aging has long been desired.
Accordingly, various solutions to the problem of recapping wine have been attempted. However, they all suffer from a variety of disadvantages.
For example, people have tried to preserve wine by placing the cork that was removed from the bottle back into the opening to seal it. However, it is often difficult to get the cork back into the bottle opening. Moreover, even if the cork is replaced, the seal created is typically less than complete, therein causing an increase in air exchange through the cork that accelerates the aging process. Further, it is also sometimes not possible to replace the cork onto the bottle of wine if the cork has been significantly damaged during removal thereof such that it is unusable.
Restaurants and other establishments that serve wine by the glass have created expensive capping systems that can be readily removed and replaced, and also remove any excess air from the bottle to assist in preserving the wine. While these systems are relatively effective, they are expensive and impractical for individual users.
It would thus be desirable to provide a wine capping device that provides a sealing cap to a wine bottle. It would also be desirable that the wine capping device has a mechanism for removing excess air from the interior of the wine bottle after recapping. It would also be desirable that such a device is easy to utilize. Further, it would be highly desirable that the wine capping device is relatively inexpensive such that it may be readily used and purchased by individuals, such as for home use.
SUMMARY OF THE INVENTION AND ADVANTAGESIt is therefore an advantage of the present invention to provide a replaceable wine cap for a previously opened wine bottle to preserve any wine that remains therein.
It is another advantage of the present invention to provide a replaceable wine cap that is capable of removing air from the interior of the wine bottle to create a vacuum chamber that preserves the wine after being placed into communication with an opened wine bottle.
It is another advantage of the present invention to provide a replaceable wine cap that is inexpensive and easily usable and reusable by individuals, restaurants or other establishments.
In accordance with the above and the other advantages of the present invention, a wine stop pump is provided. The wine stop pump sealingly recaps a bottle of wine after it has been opened, therein substantially preventing air exchange with the interior of the bottle to prevent the oxidation and subsequent spoilage of the wine. The wine stop pump includes a pumping mechanism for removing air from the interior of the wine bottle after capping that aids in preventing oxidation of the wine associated with air exchange. The wine stop pump of the present invention is inexpensive and simple to use and reuse.
Other advantages and features of the present invention will become apparent when viewed in light of the detailed description and preferred embodiment when taken in conjunction with the attached drawings and claims.
Other advantages of the present invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

The base 12 is preferably constructed of a durable, moisture resistant non-corrosive material that is inexpensive to manufacture and form to its desired configuration. In a preferred embodiment, the base 12 is formed of a thermoplastic or thermosetting polymeric material such as polypropylene. The base 12 is preferably formed by a conventional molding operation such as injection molding.
Sealingly coupled within the interior space 30 of the lower cylindrical portion 14 is a first valve assembly 40. Further, sealingly coupled within the opening 38 of the outer portion 36 is a second valve assembly 50 that, preferably, is of the same design as the first valve assembly 40. The first valve assembly 40 is positioned to allow air to move from the interior 110 of the wine bottle 100 through the first valve assembly 40 and into the interior space 30, but not allowing air to move from the interior space 30 to the interior 110 of the wine bottle 100. Meanwhile, the second valve assembly 50 is positioned to allow air to move from the interior space 30 through the valve assembly 50 and be exchanged with air outside the bottle 100, but not allow air to move from the exterior back through the second valve assembly 50 to the interior space 30. Thus, the first valve assembly 40 and the second valve assembly 50 allow air to be removed from the interior of the wine bottle 100 through the wine stop pump 10 and to the exterior of the wine bottle 100 when the wine stop pump 10 is sealingly coupled thereto. The mechanism for removing air from the wine bottle 100 through the wine stop pump 10 will be discussed further below with respect to
