ABSTRACT:
A combination cork extractor and vacuum sealer device is provided. The device is a compact, unitary tool that performs the dual function of a cork extractor and vacuum sealer for corked wine or champagne bottles. The device generally includes an elongated housing having an air passageway therein, a piston assembly that slidably engages with the inner walls of the housing, a needle assembly for injecting air into a cork bottle, a sealing assembly that operates in conjunction with a stopper to remove air from a bottle, and a plurality of one-way valves that regulate the direction of air flow inside the device. The needle assembly includes a hollow needle and an opening formed adjacent a second end of the needle. The sealing assembly includes a resilient member configured to sealingly engage with a stopper, and a plurality of openings formed in an exterior surface and fluid communication with one of the one-way valves.
