Abstract
A tamper-indicating closure serves as a closure for a container (2) which, at its container neck (3), possesses at least one locking surface (5) with which the retaining elements (6) of the tamper indicating band (7) are able to engage. The tamper-indicating band (7) possesses an upper portion (10) which extends downwards from the cap skirt (12) and which is connected with this by a frangible line (11). A plurality of retaining elements (6) are provided on the upper portion (10) of the tamper-indicating band (7). The retaining elements (6) are in each case connected with the adjacent retaining element by a flexible web (13). Each of the retaining elements (6) possesses at least one wedge shape (8) on its surface oriented towards the container neck (3).
