发明名称 Tab construction for closures having tamper evident rings
摘要 A threaded type tamper-indicating closure in which the tamper-indicating ring is separated from the cap element of the closure as the closure is opened, the tamper-indicating ring includes an upper wall member of relatively reduced thickness to enable both bending and flexing radially outwardly during installation to enable relatively rigid tabs to clear a radially outwardly extending bead on the container neck or finish. The tabs extend radially inwardly from an upper edge of a relatively thicker lower wall member of the tamper-indicating ring, and do not substantially bend or flex relative to the lower wall member during either installation or removal.
