| 摘要 |
A container closure, adapted for the formation of a sealing gasket of synthetic plastics material in situ, includes an end wall, a continuous side wall upstanding from the end wall and enclosing an inner surface of the end wall, and a plurality of spaced-apart retaining members upstanding from the inner surface of the end wall within the boundary of the side wall, each of the retaining members having a retaining surface obliquely inclined above the inner surface of the end wall. Gasket material, or a pre-cursor material, in liquid state can be introduced into the closure and can flow at least partly around the retaining members and beneath the obliquely inlined retaining surfaces to be retained, upon solidification of the gasket material, in the closure.
