Closing for containers with lids, especially those made with thin-film materials, characterized in that both the container and the lid have their free edges finished off with an internal O-rim of reduced diameter whose presence, insufficient in itself to achieve a coupling sealed, it is conjugated with the peripheral shapes of said free edges constituted by two opposing resistant zones that elastically maintain the rigidity of the larger zones comprised between them.
