<p>A cap for a container closure is adapted to receive an insert (shown in Figure 3) by engagement of a projection on the insert in a recess (34) in the cap. The cap is recessed to receive the insert in a region (40) near the open mouth (36) of the cap. The cap is outwardly flared in this region so that no significant reduction in wall thickness of the cap occurs in this region (40), the outer form of the flaring comprising a smooth curve which, in the direction towards the mouth opening (36) of the cap comprises a portion which has an outwardly presented concave curve (42) swelling smoothly from the upper wall (43) of the cap and merging by a convex curve (44) into the lower, larger diameter wall (45) of the cap. The convex curve (44) can be sharper than the concave curve (42).</p> |
