ABSTRACT:
A closure-assembly includes a molded plastic closure cap, and a disc-shaped insert liner positionable adjacent a top wall portion of the closure cap. An annular shoulder of the closure cap cooperates with the insert liner to form a top/side seal with an associated container. The annular shoulder includes at least one annular liner-engaging rib, which cooperates with the insert liner to enhance sealing performance of the closure assembly, retain the liner in position with the closure cap, and facilitate high-speed closure formation.
