A screw closure for a container has a metal body shell (30) into which a plastics moulding (44) is snap-engaged. The moulding provides a screw thread (52) for the closure; in addition, it extends below the body shell to provide a security ring (50) which is attached by rupturable bridges (62). Relative rotation of the moulding and body shell when the closure is being fitted onto a container is prevented by teeth (58) formed around the top edge of the moulding, which deeply indents the sealing gasket (38) of the body shell. <IMAGE> |
