Patent ID: 7726356

Claim:
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.
