A closure-assembly (10) includes a molded plastic closure cap (11), and a disc-shaped insert liner (30) positionable adjacent a top wall portion (12) of the closure cap. An annular shoulder (32) of the closure cap cooperates with the insert liner to form a top/side seal with an associated container (c). The annular shoulder includes at least one annular liner-engaging rib (34), 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. |
