ABSTRACT A container closure moulded from plastics material has a top 10, an internally screw-threaded skirt 11, and a tamper-evident ring 13 connected to the bottom edge of the skirt by frangible bridges 15. The radially inner surface of the ring 13 is formed with wedge-shaped inwardly projecting protrusions 16 for engaging under a security band on the neck of a container. An annular groove 20 is formed on the radially-outer surface of the ring at a location axially between the upper ends of the protrusions 16 and the bridges 15, and serves to form a hinge in an advantageous method of moulding the closure.
