Abstract
Abstract A composite closure having a plastic cap with a specially configured arrangement for retention of a plastic liner. In one embodiment, integral pedestals are provided each have an overhang, such as a mushroom-shaped head, to provide a mechanical interlock with the liner. In other embodiments, pedestals are provided each having 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, the fusible pedestals are each cylindrical. In another embodiment, the fusible pedestals are each in the shape of a pyramid.
