Abstract
A winged corkscrew has a lock box that prevents a non-stick coated worm from turning in a reverse direction and slipping out of a cork when two wings of the corkscrew are closed. The lock box locks onto a collar on a main shaft of the cork screw, and thereafter, a cam on the main shaft forms a one way rotational ratchet with the lock box. When the worm is fully inserted, the wings are lowered to remove the cork, but the ratchet prevents the worm from turning in reverse and slipping out of the cork. The corkscrew also has catches that center the corkscrew on the bottle and align the worm into the center of the cork. After the cork has been removed from the bottle, the lock box is unlocked to allow the cork to be removed.
