Gas-tight and light-tight closure for a container

US-8181809-B2

Abstract

In order to provide a reversible closure for containers which are subjected to an internal pressure in accordance with the invention there is proposed a closure device ( 200 ) comprising a deformable stretchable planarly extending cover ( 205 ) which can be moved into at least two operating positions, wherein the cover is aligned in a first operating position with the opening of the container and in a second operating position it undercuts the opening of the container over the entire periphery with a peripheral edge portion ( 222 ) so that the undercutting region ( 33 ) on the cover and the undercut region on the container form complementary sealing surfaces for gas-tightly and liquid-tightly closing the opening. The closure device further has an actuable means ( 260 ) for applying a force to the cover for deformation of the cover in such a way that it is deformable from one of the two operating positions into the other operating position.
