Abstract
A process for making a composite closure having a plastic cap with specially configured pedestals that are interconnected to a plastic liner. In one embodiment, the pedestals are each formed with an overhang, such as a mushroom-shaped overhang, to provide a mechanical interlock with the liner. In other embodiments, the pedestals are each formed with a fusible heat concentration zone that is fused to the liner as the liner is compression molded and heated in the cap. In one embodiment, each of the fusible pedestals are formed with a cylindrical configuration. In another embodiment, each of the fusible pedestals are formed in the shape of a pyramid.
