DRINKS CAN LID WITH CLOSURE CAP

摘要

The drinks can has an off-centre opening (4) in its lid (1), which is firmly connected to the body surface, and is fastened to the body surface by means of a flanged rim (3). A closure cap (8) is arranged in a rotatable but non-removable fashion, on this flanged rim (3). The closure cap (8) has two annular beads (13, 22) that are directed towards the lid (1), and of which the second annular bead (22) surrounds an opening (12) which has the same eccentricity as the opening (4) in the li d (1). The first annular bead (13) surrounds a closed region that comprises a sealing ring (16) and a deformable bulge (19). In the closed sta te of the drinks can, the sealing ring (16) rests on the apex of an annular bead (5) that surrounds the opening (4). The annular bead (13) is therefore also arranged to be off-centre, so that it surrounds the annular bead (5) when the closure cap (8) is in the appropriate rotation al position. After the convex bulge (19) has been pressed into a permanent concave position, the closure cap (8) can be rotated, so that the opening (12) in the closure cap (8) aligns with the opening (4) in the lid (1).
