1. A composite closure for a container, the 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 the flange;
an end panel received in the fitment, an upper, outer peripheral surface of the panel underlying a bottom surface of the flange and in intimate contact therewith when the composite closure is fully applied to a container;
the skirt of the plastic fitment including a radially inwardly extending circumferential contact bead that includes a substantially non-deformable vertically flat surface in cross-section that is substantially parallel to a vertical axis of the closure and axially positioned for contact with a radial outermost surface of the end panel when the closure is fully applied to the container, the bead being sized so that the vertical contact surface thereof imparts a predetermined radial force on the radial outermost surface of the end panel which produces a perceptible resistance upon initial rotation of the closure from its fully applied state and provides assurance to a user that the composite closure has been fully applied to the container prior to the initial rotation; and
an annular sealing gasket formed directly on the end panel to define a unitary integral fitment and gasket arrangement, the annular gasket having a ring shaped body, the gasket having a profile capable of forming a seal when the closure is applied to a container, wherein the gasket is composed of a non-PVC material and wherein the material comprises at least one type of rubbery block copolymer and a thermoplastic polymer.
