Abstract: The present invention pertains to a development of can caps for cans 1, 2 whose lids have a circular edge bead 3 as well as a wall section 4 that can be torn up to form a pouring opening 5. In order to close cans 1, 2 of different diameters with the same cap, the present invention provides for a longer, curved front edge web 9 and a plurality of individual webs 10, 11 at different locations from the curved front edge web 9, on the other hand, on the basic body 7 of the cap. The radial spacing 12 between the individual webs 10, 11 corresponds approximately to the thickness of the lid edge bead 3 of the can 1, 2. All the webs 9, 10, 11 are shaped such that they are able to reach behind the lid edge bead 3 of cans 1, 2 of different size in the manner of a snap cap. The cap lid is sealed against the can cap via a sealing ring 8 guided and held on the cap, which is pressed against the outer surface of the lid surrounding the pouring opening 5 of the can lid.
