A can includes a membrane seal (5), which has a continuous bead (3) in the can casing (1), the bead facing inwards in the vicinity of the can edge (8), preferably at a distance of between 1 and 10 mm from the edge. The bead is connected in a sealed manner to a sealing membrane (5), for example a foil membrane, in particular a tear-open foil. The upper part (3a) of the bead facing the can edge and the lower part (3b) of the bead facing the interior of the can, viewed when the can is upright, extend inwards either horizontally or obliquely in a uniform or alternating manner. The bead (3) can have an approximately semi-circular or triangular cross-section and preferably has an oblique lower part (3b) in order to completely empty the can. In one embodiment, a lid (7) engages in a positive fit with the bead (3) by an edge thickening (6). |
