ABSTRACT:
A device for extracting corks from wine bottles or the like includes a body and pressurized fluid container, a hollow needle extending from the body for penetration through the cork and valve mechanism for selectively injecting pressurized fluid into the wine bottle through the needle to generate gas pressure which ejects the cork from the bottle. The valve mechanism has a metering action which injects a predetermined amount of pressurized fluid in response to each valve actuation thereby avoiding inadvertant over-pressurization of the bottle. Propellant fluid is also conserved to prolong periods between rechargings of the extractor. In a preferred embodiment, a shielding member restrains uncontrolled ejection of a cork and/or needle fragment which can otherwise occur if the needle is accidently broken during operation.
