Abstract
With a cork screw having a bell-shaped housing with which a cork can be lifted out of the neck of a bottle without reversing the turning direction of the cork-screw blade and which is provided with a sleeve-like body with which the cork screw is firmly put on the neck of the bottle to be uncorked in order to lift out the cork, the lifting of the cork out of the bottle to be uncorked is often made difficult because the cork-screw blade is not centered. In order to avoid this disadvantage, there is guided in the sleeve-like body a spring-loaded piston which is located near the lower end of the sleeve-like body when the cork-screw blade is driven into the cork and through which the cork-screw blade passes centrally with a slight clearance.
