| 发明名称 | Tamper-evident closure | ||
| 摘要 | A tamper-evident closure for a container is provided. The closure comprises a first portion including inner and outer parts, and a second portion. The outer part is rotatable relative to the inner part from a first position in which at least part of the first and second portions are adjacent each other to a second position in which there is a gap therebetween. The first portion comprises locking means for irreversibly locking the closure in the second position upon a first opening so that the gap cannot be closed. The inner part includes a line of weakness which breaks if the outer part is reverse rotated relative to the inner part. | ||

A tamper-evident closure for a container, the closure comprising: a first portion including inner and outer parts; and a second portion; where the outer part is rotatable in a first direction relative to the inner part from a first position in which at least part of the first and second portions are adjacent each other to a second position in which there is a gap therebetween, the first portion comprising locking means for irreversibly locking the closure in the second position upon a first opening so that the gap cannot be closed, in which the inner part includes a line of weakness which breaks if the outer part is rotated in a second direction, opposite the first direction, relative to the inner part. | ||
