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 an odd number of evenly spaced inwardly projecting protrusions 16 for engaging under a security band on the neck of a container. The use of an odd number of protrusions ensures that no two protrusions are diametrically opposite each other and in consequence permits the closure to shift or wriggle diametrally during application of the closure to a container and thus facilitates movement of the ring 13 past the security band. 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 an annular hinge about which the lower parts of the ring 13 can pivot during application of the closure.
