A manually operated wine vacuum device that evacuates air from a partially filled bottle of wine or other oxygen-sensitive liquid prior to storage includes: (a) a body that defines a chamber; (b) a one-way de-aeration valve, and (c) a stopper that is adapted to be inserted into the interior of the bottle through the bottle's opening such that the interior of the bottle becomes in communication with the de-aeration valve which is configured so that gas flows into the chamber when the pressure in the chamber is lower than that of the interior of the bottle but gas does not flow into the interior of the bottle when the chamber is at a higher pressure. An open bottle abuts a collar formed in a recess region of the body as the bottle is coupled to the stopper and a piston slidably disposed within the chamber removes gas from the interior of the chamber when the piston is activated.

What is claimed is: 1. A device adaptable for preserving the contents of a partially filled beverage bottle that comprises: a body that defines a chamber with a first end and a second end and that defines a chamber outlet; a one-way de-aeration valve having an inlet and outlet, which allows gaseous flow into the chamber; a stopper configured and adaptable to be inserted into the interior of a bottle through the bottle's opening such that the interior of the bottle is in communication with the inlet of the one-way de-aeration valve which is configured so that gas can flow into the chamber when the pressure at the outlet of the one-way valve is lower than the pressure at the inlet of the one-way valve, but gas does not flow in the reverse direction when the pressure at the outlet of the one-way valve is higher pressure than the pressure at the inlet of the one-way valve; means for coupling the opening of a bottle to the stopper such that the outlet of the one-way de-aeration valve is located outside the bottle; means for removing gas from the interior of a bottle, that is coupled to the stopper to establish a vacuum within the bottle, and which comprises a piston slidably disposed within the chamber wherein the piston is coupled to a handle such that activation of the handle pulls the piston from the second end towards the first end of the chamber to create a vacuum force within the chamber which withdraws gas from the outlet of the one-wary de-aeration valve; biasing means for returning the piston to the second end of the chamber once the piston is released from the pull of the handle and wherein the chamber outlet is configured so that the chamber is in gaseous communication with the atmosphere that is exterior of the device even when the piston is at the second end of the chamber; and means for manually opening the one-way de-aeration valve, without having to activate the handle, to allow gas to flow into a bottle that is coupled to the stopper. 2. The device of claim 1 wherein the piston is coupled to a repelling spring such that activation of the handle creates tension in the spring sufficient to return the piston to its original position within the chamber once the piston is released from the pull of the handle. 3. The device of claim 1 wherein the stopper comprises a cylindrical member having one or more ring-shaped ribs formed on its outer circumference. 4. The device of claim 1 wherein the one-way de-aeration valve comprises a duckbill-type valve. 5. A method of preserving the contents of a partially filled beverage bottle having an opening through which the beverage can be poured that comprises the steps of: mounting a device as defined in claim 1 onto the opening such that the outlet of the one-way de-aeration valve is located outside the bottle; manually activating the means for removing gas from the interior of the bottle to withdraw gas from the interior of the bottle; and storing the bottle until consumption of the beverage is desired at which time, activating the means for opening the one-way de-aeration valve to allow gas to flow into the bottle. 6. The method of claim 5 wherein the beverage is wine. 7. A device for retarding oxidation of wine or other liquid in a bottle that comprises: a housing that defines a hollow chamber that has a first end and a second end and that defines a chamber outlet that establishes gaseous communication between the chamber and the atmosphere that is exterior to the device; a biasing spring disposed within the hollow chamber; a piston slidably disposed within the hollow chamber; a handle that is operably connected to the piston such that operating the handle pulls the piston from the second end towards the first end of the hollow chamber, wherein the chamber outlet is configured so that the chamber is in gaseous communication with the atmosphere even when the piston is at the second end of the hollow chamber; a one-way de-aeration valve having an outlet that is in communication with the chamber and an inlet; a stopper configured to be inserted into the interior of a bottle through its opening such that the interior of the bottle is in communication with the inlet of the one-way de-aeration valve and wherein the outlet of the one-way de-aeration valve is located outside the bottle; and means for manually opening the one-way de-aeration valve without having to operating the handle. 8. The device of claim 7 further comprising means for coupling the opening of the bottle to the stopper. 9. The device of claim 7 wherein the handle is connected to the piston by an inelastic cord whose direction of moving is directed by a guide pulley. 10. The device of claim 7 wherein the one-way de-aeration valve comprises a duckbill-type valve. 11. A method of retarding the oxidation of a wine or other liquid that partially fills an opened bottle having an opening which comprises the steps of: mounting a device as defined by claim 7 adjacent the opening such that the opening is coupled to the stopper and wherein the outlet of the one-way de-aeration valve is located outside the bottle; removing air from the bottle by manually activating the handle; storing the bottle; and activating the means for opening the one-way de-aeration valve to allow gas to flow into the bottle. 12. The method of claim 11 wherein the beverage is wine.
