Abstract
This bottle opener is designed to remove screw caps off of beer bottles with little effort. Primarily, it consists of a base cap with left hand threads on the interior, for engagement with the outer threads of a screw cap on a filled bottle. It also is provided with a locking band in the top portion that locks a bottom end of an empty bottle in the device, so as to serve as a handle and also provide mechanical advantage for easy rotation to remove the screw cap from the filled bottle.
