Opener with key ring

Bottle Opener with Key Ring A bottle opener is a device that enables the removal of metal bottle caps from bottles. More generally, it might be thought to include corkscrews used 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. A simple opener is just a piece of metal with a rectangular or rounded opening in one end and a solid handle large enough to be gripped between the thumb and forefingers on the other. The opening contains a lip that is placed under the edge of the bottle top, pulling it off when upward force is applied to the handle end of the opener. This type of opener is small and durable, so it is frequently used as a key fob.
