Abstract
A screw cap for a container. The cap comprises an inner member having an annular sidewall with an internal screw thread for screwing the cap onto a threaded opening of a container; and an outer member having a skirt enclosing the sidewall of the inner member, the outer member being coupled to the inner member to prevent displacement of the outer member relative to the inner member parallel to an axis defined by the screw thread. The cap has a first configuration in which the outer member is rotatable with respect to the inner member to prevent the cap from being unscrewed and a second configuration in which the skirt engages with the sidewall of the inner member so that the cap can be unscrewed by rotating the outer member.
