TAMPER EVIDENT CAP AND CONTAINER

摘要

A cap (26) and container (10) combination wherein the cap (26) fits about the container (10) in at least two closure positions. Two circumferential bands (29, 30) are provided around the skirt (28) of the cap (26) and there is an internal thread (31) which engages an external thread about the container neck (13). In the first position, one band of the cap (26) engages a circumferential slot (21) about the container (10). The internal thread seals with the top of the container (10). The first band (29) is removed and the container opened by removing the cap. In the second position, the second band (30) engages the slot and the threads engage each other. In the second position, the second band (30) is located about the container (10). It remains in position when and after the cap (26) is removed. Tampering of the container (10) and cap (26) can be visually detected with this configuration. A bead (19) about the container (10) is formed of a reduced cross-section in portions circumferentially around the cap (26). This facilitates assembly and disassembly of cap (26) and container (10).
