TAMPER EVIDENT CLOSURE

摘要

A closure (24) opens by a user-actuated rotation of a closure element (42) relative to a closure body (40) about a longitudinal axis (500). The element (42) (e.g., a cap (a sealing cap or alternatively just an overcap) or valve element) has a tamper-evidencing tab (90) extending upward from a lower wall (77) of the element (42). The tab is initially captured in a recess (94) in an upwardly projecting wall (52) of the body. The tab may be severed to permit an opening rotation of the element (42).
