摘要
A closure (2A) overlies a liner (6) which seals a container mount defined by a peripheral edge (12) of the container. The liner (6) includes a sealing flange (31) having an upstanding outermost terminal rim (40) of resilient material which is folded inwardly during closing movement of the closure shell (2A) toward the sealing flange (31) to form an unflattened fold constituting a biasing means for biasing the periphery of the sealing flange (31) against the peripheral edge (12) of the container mouth.
