- 10 - ABSTRACT OF THE DISCLOSURE A container closure blank adapted for the formation of a sealing gasket of synthetic plastics material in situ in the blank, 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 has a retaining surface obliquely inclined above the inner surface of the end wall. Gasket material, or a precursor material, in liquid state can be introduced into the closure blank and can flow at least partly around the retaining members and beneath the obliquely inclined retaining surfaces to be retained, upon solidification of the gasket mater- ial, in the closure blank.
