摘要：A tamper-proof plastic closure (1) has a closure cap (2) on which a tamper-proofstrip (6) is attached by means of intended tearing webs (5). The tamper-proof strip (6) isprovided with a multiplicity of blocking elements (8). The blocking elements (8) areconnected to the tamper-proof strip via joint elements (7). While the closure is being
screwed onto a container neck, the blocking elements (8) can be pivoted upwards andradially outwards into a first closure position (I). When the tamper-proof closure isopened, the blocking elements are, in contrast, pivoted downwards and radially inwardsinto a second opening position (II). The free inside diameter is reduced during thisprocess, as a result of which the blocking element is kept in engagement withcorresponding blocking surfaces on a container neck.
