The screw cap (1) is for a bottle having a screw neck. It has inner and outer caps (2,3) comprising respectively an end (4,5) and a skirt (6,7). It has first drive (8) ratchet between the skirt and a second drive ratchet (9) associated with a (10) resilient ring formed integrally with the outer cap (3). To tighten the closure on a bottle, the outer cap is rotated, the first drive driving the caps in unison. If the outer cap is now unscrewed, the ratchets click over the dogs (13) and the inner cap is not unscrewed until the outer cap is depressed to overcome the force of the ring.
