Title: Bottle cap

Abstract: A bottle cap which reliably seals a bottle at high and low temperatures and which nevertheless can easily be removed by hand without a tool. The cap is made of two parts: An outer cap member of hard plastic material and a sealing insert of soft plastic material. In the closed position the outer cap member is fixed against the inner sealing member by means of a detachable opening ring, which firmly holds the sealing insert clinging to the bottle opening.
