Abstract
The invention relates to a can lid of a conventional design, in particular intended for beverage cans, whose special feature comprises the fact that a substantially ring-shaped molded plastic part is fastened to the lower side of the lid surface surrounding the opening region to form an opening that is sealingly reclosable, in that a plastic stopper part is fixedly connected to the lower side of the tongue tab that is upwardly pivotable during the opening procedure and sealingly engages into the molded part, and in that the peripheral contour of the tongue tab is preferably disposed in the region of the molded part at a predefinable spacing from the stopper part.

A can lid, the can lid comprising:
- an opening region in the form of a tongue tab that is provided in metallic lid material of a lid surface;
- a two-armed lever member intended for opening this opening region, the two-armed lever member being firmly connected to the lid material in the opening region, and the two-armed lever member being configured to serve for an upward pivoting of the tongue tab during the opening procedure,
- a substantially ring-shaped molded plastic part, with the substantially ring-shaped molded plastic part being fastened to a lower side of the lid surface while surrounding the opening region to form an opening that can be sealingly closed again;
- and
- a plastic stopper part, the plastic stopper part being firmly connected to the lower side of the tongue tab, the tongue tab being able to be pivotably opened during the opening procedure and the plastic stopper part sealingly engaging into the molded part.
A can lid, the can lid comprising:
- an opening region in the form of a tongue tab that is provided in metallic lid material of a lid surface;
- a stopper part, the stopper part being firmly connected to the lower side of the tongue tab, wherein the tongue tab connected to the stopper part at the lower side is separated from the lid surface by a microgap extending over the periphery of the tongue tab;
- wherein a tongue tab base connected to the lid surface forms a pivot bearing that becomes effective during an opening procedure;
- and
- wherein the lower side of the metallic lid is firmly adhesively coated with a sealing plastic material.
A can lid, the can lid comprising:
- an opening region in the form of a tongue tab that is provided in metallic lid material of a lid surface;
- wherein the tongue tab of the metallic can lid is separated from the lid surface surrounding it while forming mutually engaging projections and recesses by a cutting procedure;
- and
- wherein the tongue tab and the lid surface adjacent thereto are connected via the mutually engaging projections and recesses in a shape-matched and force-transmitting manner while forming a microgap, with a leak tightness of the completed, unopened can lid being ensured by a sealed on molded plastic part covering the microgap.
