Abstract
A cap for a container closure is adapted to receive an insert by engagement of a projection on the insert in a recess in the cap. The cap is recessed to receive the insert in a region near the open mouth 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, the outer form of the flaring comprising a smooth curve which, in the direction towards the mouth opening of the cap comprises a portion which has an outwardly presented concave curve swelling smoothly from the upper wall of the cap and merging by a convex curve into the lower, larger diameter wall of the cap.
