<p>The invention relates to a closure for a drinks can having a rotary lid (2) which is fastened at a rivet (5) of the can lid (D) such that it can be rotated over the pouring opening (7) from an opening rotary position into a closure rotary position, and back again, and is designed, at least in certain regions, as a curved snap-action disc (S) which, by virtue of forces acting perpendicularly to the lid-surface plane, can be transferred by bending, and once a pressure point has been overcome, from a stable first state of curvature into a stable second state of curvature, in which the outer periphery (10) of the rotary lid (2) is positioned with a closure pressure against the lid periphery (9) binding the pouring opening (7), and out of which the snap-action disc (S) springs back into its first state of curvature under the renewed action of force.</p> |
