Abstract
An improved cork-extracting device having a gas bomb filled with carbonic acid gas, inert gas or the like. The gas in the bomb is fed into the air-space present below the cork of the container, such as a bottle containing beverages such as wine, through a insertion needle whereby the pressure in the container raises to remove the cork automatically. The cork-extracting device is characterized in that a valve seat of a needle valve, which opens and closes the gas supply port, is made of a resilient valve seat plate, the lower surface of the resilient valve seat plate being used as a packing for supporting the cap of the gas bomb, accommodated in a cylindrical container, and the needle valve being able to protrude the resilient valve seat plate to open the cap of the gas bomb.
