Abstract
In a method of closing a container having an external screw thread with a cap having an internal thread, the cap is located on the container in a pre-positioning or predetermined angular position corresponding to its final angular position and is then pressed into final closed position by axial force. The cap is located in the pre-positioning position by resilient abutments such as an internal seal, head seal, or projections on the cap which are overcome by the pressing force.
