Abstract: The closure assembly of FIGS. 1 and 3 comprises a container 1, a cap 2 having a skirt portion 3, and a captive band 4 attached via a tamper-evident tear-off band 5 and a pair of frangible connections 6 and 7 to the skirt portion 3. Arrows 8 on the skirt 3 and 9 on the container 1 show that the cap 2 has been put on in the aligned position. A tab 10 on one end of the tear-off band 5 provides a grip for the fingers in removing the band. In FIG. 3 the tab 10 has been torn away to reveal a detent means on the container neck in the form of a projection 11. This is partly situated in a gap 19 under the tab 10 before this has been lifted away, and partly under the start end of the tear-off band 5, which is adapted to flex slightly to accommodate the projection 11 without any significant damage to the frangible connections 6 and 7.
