(54) Container closures


(57) This invention relates to container closures and to methods of sealing the container neck on filling of the containers.
A closure assembly comprises a plug 4 adapted to be inserted into the neck 1 of a container to effect an aseptic seal with the container neck 1 and a cap 11 comprising a skirt 13 provided with formations 12 that are adapted to co-operate with complementary formations 2 provided on the container neck 1. The cap 11 and the neck formations 2 are so arranged that the cap 11 can be turned from a fully applied condition to a release position for removal of the cap 11 from the neck 1, the plug 4 being adapted to be inserted into the neck 1 to effect an aseptic seal of the neck 1 prior to application of the cap 11. On subsequent removal of the fully applied cap 11 from the neck 1, the plug 4 is withdrawn from the neck 1 by being held captive to the cap 11.
