Child-resistant tamper-evident closures.

摘要

In a closure assembly of the snap-on kind in which child-resistance is achieved by requiring that the cap be turned to a predetermined orientation (e.g. as indicated by arrows) before it can be pushed off, tamper-evidence is provided by a tear-off strip (8) on the skirt of the cap (1) co-operating with the neck in a way which prevents rotation of the cap to that orientation.Consequently the neck does not need to have a bead under which the tamper-evident strip engages. There may be teeth (9,11) on the inside of the strip and on the outside of the neck.
