摘要

Container closure (1) having a peripheral edge (2) enclosing an opening surface (4) and at least three shutter blades (6) each extending from the peripheral edge (2), having an end portion (12) and facing away from the edge (12). 2) in the direction of the end portion (12) extending first and second side boundaries (8, 10) and one of these first and second side boundaries (8, 10) respectively connecting edge boundary of the end portion (12), wherein the shutter blades (6) in pairs adjacent to each other and circumferentially on the edge (2) are arranged and are foldable in the direction of the opening surface (4), wherein in the opening surface (4) folded and the opening surface (4) closing state respectively adjacent shutter blades (6) in the region of their respective adjacent first and second side boundaries (8, 10) at least partially overlap under closure of the opening surface (4), wherein the Endabschnit te (12) of the shutter blades (6) overlap at least in pairs at least in parts and / or interlock, at least two, in particular all, shutter blades (6) each at least two of the first and / or second side boundary (8, 10) and / or weakening lines (14, 14 ', 14 ") extending from the edge boundary of the end section (12), wherein the at least two shutter blades (6), in particular all shutter blades (6), have at least two weakening lines, also" first weakening line "(FIG. 14) and "second weakening line" (14 '), which have a common starting point (20) and the common starting point (20) of the at least two weakening lines (14, 14') at or in the region of the first side boundary (8). the second side boundary (10), the edge boundary of the end portion (12), in the transition from the first side boundary (8) to the edge boundary of the end portion (12) or is present in the transition from the second side boundary (10) to the edge boundary of the end portion (12).
