Abstract

The tamper-proof snap-on closure (1) is particularly suitable for bottles with beaded edges on the bottle neck. The tamper-proof safeguard is effected by a shear-off element (4) which consists of a push piece (9) and is bounded on both sides by weak points (5, 6). The shear-off element (4) forms part of the shell. In order that the shear-off element (4) does not tear further than is desired, the weak points (5, 6), running in the axial direction of the closure, extend only into the region of an annular bead (2) arranged on the inside surface of the shell. The shear-off element (4) itself, which has at least one rib (11), is connected to the shell via a film hinge and can be swivelled through 90 DEG , thus destroying the weak points. <IMAGE>
