SCREW ON CONTAINER CLOSURES

摘要

A screw on container closure (30) comprises threads (24) which include ratchet formations (26) for co-operation with complimentary formations on a threaded container neck, the ratchet formations (26) allowing the closure to be screwed on to the neck but resisting unscrewing of the closure from the neck. Tamper indicating contents access means may be provided, for example in the form of a tear-out wall (34). A snap on re-closure cover (50, fig. 10) may be provided, for protection of the container contents once the wall (34) has been removed.
