Abstract

A plastic tamper-indicating closure (1) possesses a closure cap (2) on which, by means of weakened web portions (5), a tamper-indicating band (6) is fixed. The tamper-indicating band (6) is provided with a number of blocking elements (8). The blocking elements (8) are connected with the tamper-indicating band via integral hinges (7). During screwing onto the container neck, the blocking elements (8) can be pivoted upwards and radially outwards into a first closed position (I). As opposed to this, during opening of the tamper-indicating closure the blocking elements are pivoted downwards and radially inwards into a second opening position (II). With that, the effective internal diameter will be reduced, by which means the blocking element will be held in engagement with the corresponding locking surface on a container neck.
