Abstract
A composite closure for a bottle or like container is disclosed which includes a compression molded plastic cap and a plastic sealing liner retained within the cap. Effective retention of the sealing liner in position within the plastic cap is provided by an inwardly extending annular lip disposed between an internal thread formation of the plastic cap and its top wall portion, and a ring of projections extending integrally from the inner surface of the top wall portion of the cap. The sealing liner includes an annular bead portion adjacent to and in engagement with the annular lip and ring of projections so that the liner is effectively retained in position within the plastic cap.
