neck of a container (7), said closure comprising crown (1) and a peripherally depending
skirt (2), said liner being formed of a resilient material retained on the under side
of the crown and being provided at its intended point of abutment with the rim (10)
of the container neck (9) on its downwardly directed face with a pair of radially
annular ribs (19, 20) for cooperation with the rim of the container neck for with
which it is to be used, wherein the pair of concentric annular ribs are disposed adjacent
each other with their juxtaposed faces (21) exceeding in width the contact surface
of the rim (10) of the container neck with the proviso that the radially inner of
said ribs (20) does not comprise an unsupported inclined plane. This arrangement allows
for better sealing of container closures, particularly those formed of plastics material
