Abstract
Apparatus and method for removing a stopper from a bottle having an internal pressure greater than the ambient pressure surrounding the bottle, e.g. a champagne bottle. At least one generally vertical edge of the apparatus is placed in a generally vertical groove in the periphery of the stopper, in some cases cutting the groove simultaneously as it is moved downward over the stopper. The apparatus is then oscillated or rotated, whereupon the internal pressure in the bottle can overcome the sliding friction between the stopper and the bottle. The apparatus is also adapted to control the stopper, once expelled.
