COMPOSITE CLOSURE

摘要

A composite closure which includes an end panel that is received in a circular plastic fitment having a central opening therein defined by an inwardly extending flange which overlies an outer periphery of the end panel and an integral skirt downwardly depending from the flange. The fitment includes a radially inwardly extending circumferential bead or bead segments which include a substantially non-deformable flat vertical surfaces that are substantially parallel to the axis of the closure and axially positioned to contact the radial outermost edge of the end panel when the closure is fully applied to a container. The bead or bead segments are configured to impart a predetermined radial force on the end panel which produces a perceptible resistance upon initial rotation of the fully applied closure and provides assurance to a person removing the closure from the container that it has been fully applied to the container.

主权项

1. A composite closure for a container, said composite closure comprising:
a circular plastic fitment having a central opening defined by an inwardly extending circumferential flange and a downwardly depending skirt extending from said flange; an end panel received in said fitment, an upper, outer peripheral surface of said panel underlying a bottom surface of said flange and in intimate contact therewith when said composite closure is fully applied to a container; said skirt of said plastic fitment including a radially inwardly extending circumferential contact bead that includes a substantially non-deformable flat vertical surface that is substantially parallel to the axis of said closure and axially positioned for contact with a radial outermost surface of said end panel when said closure is fully applied to said container, said bead being sized so that the vertical contact surface thereof imparts a predetermined radial force on said radial outermost surface of said end panel which produces a perceptible resistance upon initial rotation of said closure from its fully applied state and provides assurance to a user that said composite closure has been fully applied to the container prior to said initial rotation.
