Abstract
A can lid is described that is in particular intended for beverage cans and that differs from the generally known metallic can lids in that the opening region is configured as a tongue tab that is separated from the lid surface by a microgap, in particular a punched gap, extending over the tab periphery and the tongue tab base connected to the lid surface forms a kink bearing that becomes effective on the opening procedure and that is connected to the lid surface, and in that the lower side of the metallic lid is in particular coated over its whole surface in a firmly adhering manner with a plastic material, in particular a plastic film, and this coating is weakened, in particular notched, adjacent to the microgap between the tongue tab and the lid surface.
