Abstract
A method for applying a threaded closure to a container, said closure having sealing means in or towards the crown thereof, which method comprises applying the closure to the container by the application of a predetermined rotary torque thereto, continuing the application of the closure to the container until the desired torque applied is obtained and thereafter applying axial pressure to the closure crown towards and on to the container while simultaneously applying said torque whereby the closure pressure serves to disengage the threads to overcome at least some of the friction therebetween to permit a greater proportion of the applied torque to be applied to the sealing means within the closure.
