Abstract

A tamper-proof closure (1) consists of a closure cap (2), which is provided with an internal thread and can be screwed onto a container neck designed with a complementarily arranged counter-thread and an annular projection, in particular a transfer ring, provided below the counter-thread, and of a security ring (10) which is connected by its upper edge via connecting points and/or intended tearing points to the lower edge of the closure cap (2). At least two, possibly interconnected, locking projections (17), having ribs on their outer surfaces in accordance with particularly preferred embodiments, are continued downwards, extending beyond the underside of the security ring (10) in the manufacturing position, and are connected to the underside of the security ring (10) via a hinge or film hinge (27) per locking projection (17). According to a preferred embodiment, the hinges or film hinges (27) are formed in that the internal diameter of the locking projections (17) is slightly smaller than the external diameter of the security ring (10). To engage below the annular projection, in particular transfer ring, the locking projections (17) are folded relatively inwards in particular by a specially designed die, preferably between two defined end positions, producing a pivoting resistance beyond a dead centre point, and have particularly preferred...
