A child resistant closure for a container (1) comprises a collar (3) fixable to a container (1) and a rotatable cap (4). The cap (4) is provided with a first engaging member (10) and the collar (3) is provided with a corresponding second engaging member (21). Adjacent said engaging member the collar (3) is provided with a resiliently deformable integral push tab (24), characterised in that the first and second engaging members (10, 21) are adapted to engage by rotation of the cap (4). It is an advantage of one embodiment that the cap of the closure does not require an internal screw thread. The cap may therefore be simpler and less expensive to manufacture. In addition, the two components, e.g., the cap and the collar, can be assembled prior to application onto the container.
