Bottle opener

A bottle opener or bottle cap opener is a device for removing metal bottle caps from glass bottles. More broadly, it could include corkscrews to remove cork or plastic stoppers from wine bottles.

A metal bottle cap is affixed to the rim of the neck of a bottle by being pleated or ruffled around the rim. A bottle opener is a specialized lever inserted beneath the pleated metalwork, which uses a point on the bottle cap as a fulcrum on which to pivot.
