<p>The closure has a socket (3) connected with a nipple (5) by a strap (4). A membrane (7) is held at the nipple by a spring element so that the membrane sealingly closes the nipple by lower force of the spring element. The membrane forms a plunger (9) on an upper side, where the plunger overlaps the nipple. A cap cover (6) is formed by a hinge (18) at an upper end of the socket that forms an elastic coupling (13). The plunger is actuated downwards against a force of the spring element by elastic pressing of the coupling with closed cap cover so that the membrane is lifted from nipple edge.</p> |
