Abstract
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.
