Abstract:
A closure (1) for a one-piece drink can, which closure can be opened with one hand, said closure comprising a projection (3) in the shape of an acute-angled triangle having substantially abrupt walls (4), which projection (3) rises from its shortest side towards its most acute angle such that the walls (4) are most abrupt around said most acute angle, said projection (3) provided with a peak from which first and second reducing scores (5) start, said scores (5) being aligned with a joint between the abrupt walls (4) of the projection (3) and the closure (1), wherein guide score (6) continues away from a joinder between the first and second reducing scores 5, and the closure (1) tears along scores (5, 6) when the projection (3) is pressed down against the closure (1), said closure having a smoothly concave area (2) around the projection (3) as viewed from above, and wherein said first and said second reducing scores (5) run in alignment with longitudinal sides of the projection (3) in the vicinity of the peak of the projection (3) and thereafter diverge from the side walls (4) of the projection (3) as scores 5 approach a bottom end of the projection, said scores 5 ending substantially at an edge of the concave area (2).
