Patent ID: 8225959

Claim:
A method of extracting fluid from within a container sealed by a cork comprising the steps of: inserting at least one smooth exterior walled non coring needle beyond said cork and into the container, wherein said at least one needle is operable to maintain the integrity of the cork to prevent unwanted gaseous or liquid ingress or egress after removal of said needle; injecting a pressurized non-reactive gas into said container through at least one of said hollow needles thereby causing an increase of pressure within said container to a level higher than the surrounding atmospheric pressure; allowing said fluid within said container to be forced out of said container by said pressure through at least one of said needles until a desired amount of fluid is extracted; regulating the delivery of the gas such that flow of the fluid is achieved while the volume of fluid in the container is decreased by increasing or maintaining the pressure in the container and limiting the pressure to prevent the expulsion or leakage around the cork; removing said at least one needle from said cork thereby allowing said cork to reseal; said extraction of fluid from a container is achieved without the removal of said cork and exposing the fluid to air.
