ABSTRACT:
An apparatus for removing a soft stopper such as a cork from a container such as a bottle. The apparatus includes a hollow cylinder having one or more slits along its length and a handle attached to the top of the cylinder. The interior surface of the cylinder includes one or more spiral wound threads having a flat upper surface. The cylinder is inserted between the outer circumference of the cork and the interior wall of the bottle and is rotated so that the threads are embedded in the outer wall of the cork and serve to compress the cork inwardly as the apparatus is screwed into the container. A stop ring serves to limit the penetration of the apparatus into the bottle and when the apparatus has reached its maximum penetration, the apparatus begins to force the cork out of the bottle as the turning motion of the cork continues. Various embellishments serve to enhance the efficiency of operation of the device.
