Abstract
A device for extracting a cork from a bottle. The device leverages an axial and rotational pulling force, and pressurized gas in the interior of the bottle to displace a cork from a bottle. The device provides a helical-shaped lever that axially and rotatably penetrates through the cork to forcibly extract the cork from the bottle neck. The helical-shaped lever has a hollow passageway that is in communication with the interior volume of the bottle. The device further includes a gas cartridge operated by a pressure release button that discharges pressurized gas through the hollow passageway of the helical-shaped lever, and into the bottle. The moment at which helical-shaped lever fully penetrates the cork, tension is removed from helical-shaped lever, releasing a compressed spring to expand. Expansion of spring presses spring against pressure release button; thereby forming tactile feedback and indicating optimal moment to discharge pressurized gas.
