Abstract

An improved cork closure for beverage and wine bottles having a recess on the outer face of the closure. The recess is designed to facilitate the extraction process by providing central constraint on the position of the corkscrew on the face of the closure and to guide the corkscrew along the axis of the closure. This recess does not interfere with any other type of extraction device.
