SCREW CLOSURE WITH TAMPER-PROOF STRIP

The present invention relates to a screw closure with tamper-proof strip, wherein the screw closure (10) has a head plate (1), an at least approximately cylindrical cap skirt (2) comprising a female screwthread (11), and the tamper-proof strip connected to the lower edge of the cap skirt (2) by way of an easily tearable connection (8), the strip being in the form of a flexible strip (3), comprising a first portion (4) directed downward from the cap skirt (2) and a second portion (5) which is attached at the lower end of the first portion (4), and which is folded over inwardly and back in the direction of the head plate (1), for engaging behind a securing ring (21) on a container neck (20), wherein at least one extension (7) is provided in axial extension of the second portion (5), the extension being attached to the outer free edge of the inwardly folded-over second portion (5); and leaving the inner edge thereof free. The second portion has at least one recess and extends along the inner circumference of the screw closure. In order to create a screw closure having a tamper-proof strip with the features set forth in the opening part of this specification, which admittedly still has the advantage of easy applicability but at the same time also has increased functional reliability in that it opposes greater resistance to unrolling across the lower hinge region so that it is practically impossible to release the closure by turning over the second portion of the tamper-proof strip, the invention proposes that the extension (7) extends in the peripheral direction over the at least one opening (9) provided in the second portion (5).
