<p>A closure (1) for closing a container, particularly for closing the aperture piece (10) of a bottle, comprises a closure body with a front face (3), a lateral wall (2) and a transition region (4) between the front face (3) and the lateral wall (2). An annular protrusion (8) that extends from the front face (3) is provided for supporting the protrusion (8) on the upper side (10a) of the aperture piece (10). An external seal (9) is configured as a tongue (9) extending from the lateral wall (2) and/or the transition region (4) in the direction of a central axis (A) of the closure (1). The tongue (9) is configured in such a thin manner that it flexibly rests on the contour of the outer edge (10b) and/or the outer side (10c) of the aperture piece (10) while the the closure (1) is mounted to the aperture piece (10). In addition, the length of the tongue (9) is dimensioned in such a way that the tongue (9), in any position it can take when subjected to an external force, has no contact with the protrusion (8) and that the free end thereof is arranged at a distance from the protrusion (8).</p> |
