  • Patent number: 11447290
    Abstract: A can lid (14) for an aluminum beverage can is disclosed and has a pull tab (38), a chuck wall (26) defining a plug diameter B, a countersink (28) and a central panel (30) having a panel radius (48). On the central panel, a score line (34) defining a tear panel (32) and a rivet (40) for connecting the pull-tab to the can lid are arranged. The lid has a lid plug diameter of between 45 to 49 mm, an outside diameter of between 52 to 55 mm, and a weight of less than 1.9 g. The central panel has a thickness of less than 0.19 mm. The rivet is arranged off-center on the central panel. The rivet is tilted, so that the rivet provides an axis of rotation of the pull tap that has an angle of between 2° and 4° with respect to an axis that is vertically orientated with respect to the central panel, and/or at least one ramp-up bead (56) is arranged on either side of pull tab or on both sides of the pull tab.

  • Publication number: 20160318645
    Abstract: The invention relates to a can body (10) for a beverage can, which can body is formed from aluminum sheet metal as a single piece and has a circumferential wall (12) and a can bottom (14), which can bottom has a cup-like central section (16) curved inward and a standing section (18) that annularly surrounds the central section and is curved outward. The standing section curved outward is connected to the circumferential wall by means of an outer transition section extending aslant in the cross-section and defines a standing ring, along which the standing section at least approximately touches a flat surface when the can body is placed on such a flat surface. According to the invention, the can body has a diameter of less than 56 mm and the greatest sheet metal thickness of the formed aluminum sheet metal in the region of the cup-like central section curved inward is less than 0.25 mm.
