It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details or with other methods. In other instances, well-known structures or operation are not shown in detail to avoid obscuring the invention.

[0019] Referring now to FIGS. 1-8, where like numerals indicate like features, an exemplary electrically powered bottle opening and beverage preservation device 10 is shown. Referring first to FIGS. 1, 2 and 6, a left housing 12 is affixed to a right housing 14 and an electrical switch 16 is disposed on the surface of the device 10. An air inlet 18 is also located on the surface of the device 10. Affixed to a bottom distal end of the device 10 is a cylindrically shaped guide 20. A non-coring needle 24 extends longitudinally from the bottom distal end of the device 10 and the needle 24 is located concentrically to the guide 20. The needle 24 is configured to pierce the cork/stopper of the bottle 42 and extend past the cork/stopper 44 into the internal volume of a bottle. The guide 20 is configured to fit around the neck area of the bottle 42 and help guide the needle's 24 insertion into the cork/stopper 44 of the bottle that is to be opened. A pair of diametrically opposed slots 21 run down the guide 20 and a slide 22 is disposed in the slots 21. The slide 22 is configured to move up and down the length of the needle 24 to remove a cork/stopper that is attached to the needle 24 when the cork is removed from the bottle.

[0020] Referring now to FIGS. 3 and 4, the internal components of the device 10 will now be described. FIG. 3 has the guide 20 removed for clarity. Located at a top distal end of the device 10 is a charging connector 29 which is configured to accept an electrical connection in order to recharge a battery pack 26. A charging circuit 28 is disposed near the connector 29 and the battery pack 26, the charging circuit is configured to safely and reliably recharge the battery pack 26 in any well known manner. An electrical motor 30 is disposed in the device 10. The electric motor 30 is powered by the battery pack 26 and the electrical switch 16 is configured to turn the motor 30 on and off as required by the user. In a preferred embodiment, the motor 30 is a 12 volt direct current motor but any suitable motor will work.

[0021] A motor gear 32 is rigidly affixed to the shaft of the motor 30 and is configured to mesh with a piston gear 34. The motor gear 32 may be a bevel gear that meshes with a bevel piston gear 34. The piston gear 34 is rotatably affixed to a frame 17. The frame 17 may be configured to be rigidly affixed to the motor 30 and the right housing 14. Affixed to the piston gear 34 is a piston 36. The piston 36 is affixed to the piston gear 32 so that it moves in a back and forth motion as the piston gear 34 rotates. The piston 36 translates back and forth in a compressor cylinder 38. Compressor cylinder 38 has been removed from FIG. 4 to more clearly show the location of the piston 36.

[0022] The piston 36 creates a positive pressure, the pressure stroke, as it is forced forward in the compressor cylinder 38 by the rotation of the piston gear 32. This positive pressure of air is transferred through the needle 24 and out of the orifice 24a into the internal volume of the bottle that is to be opened. As more and more pressurized air is transferred through the needle 24 into the internal volume of the bottle, the internal pressure in the bottle increases rapidly. The increased internal pressure in the bottle will act to force the cork/stopper out of the bottle. Through experimentation it has been found that most corks/stoppers will release from the bottle when an internal pressure in the bottle is between 30-55 psi. An air inlet passageway 40 is provided adjacent the compressor cylinder 38. The inlet passageway 40 is configured to communicate air from the air inlet 18 to the compressor cylinder 38.

[0023] Referring now to FIGS. 5 and 8, which shows a simplified view of the air compressor components, a needle check valve 39 (FIG. 8) is disposed in the compressor cylinder near the inlet to the needle 24, in any well known manner, to direct the pressurized air into the bottle during the pressure stroke. The needle check valve 39 is also configured to prevent air from being drawn out of the bottle when the piston is drawn backward in the compressor cylinder 38. In this manner, air may only travel into the bottle through the air outlet 37 (FIG. 8). An inlet check valve 41 (FIG. 8) is also disposed in the compressor cylinder 38 adjacent to an air inlet 40. The inlet check valve 41 is configured to prevent the compressed air from traveling into the air inlet 40 during the compression cycle but allows air into the compressor cylinder 38 when the piston 36 is retracted. In this manner, ambient air is drawn into the compressor cylinder 38 when the piston 36 is retracted and the compressed air is forced into the needle 24 through the air outlet 37 and hence into the bottle during the pressure stroke.

[0024] Referring now to FIG. 7, which shows the bottle opening and beverage preservation device 10 being used as a beverage preservation system, whereby air in the bottle 42 is pumped out of the bottle to create a vacuum internally in the bottle. It has been shown that for some beverages, such as for example wine, extended exposure of the wine to oxygen causes the wine to oxidize and spoil. It would therefore be advantageous to remove the air from the bottle to prevent the air from reacting with the remaining beverage in the bottle. A stopper valve 46 is configured to be inserted into the mouth of a bottle 42 such that the stopper valve 46 seals the bottle 42. The stopper valve 46 is also configured to be sealingly inserted into the air inlet 18 that is disposed on a surface of the device 10. The stopper valve 46 is configured to allow air that is internal to the bottle 42 to be drawn out of the bottle 42 when it is in communication with the air inlet 18 thereby creating a vacuum (negative pressure) when the device is turned on internal to the bottle 42. When the stopper valve 46 is removed from the air inlet 18, the vacuum created in the bottle acts to close the stopper valve 46 and prevent air from entering the bottle 42. In this manner, air is drawn out of the bottle 42 by the device 10 thereby substantially reducing the amount of oxygen in the bottle which thereby acts to preserve the beverage still contained in the bottle 42.
