Abstract
The object of the invention is an aluminium or an alloy closure capsule adapted to be crimped onto the neck of a bottle and of which the ring comprises a shoulder, the skirt of this capsule comprising a retaining ring or peripheral rib which, after the capsule has been crimped onto the neck, will define with the portion of the skirt covering the top edge of the said shoulder of the neck an annular groove permitting guidance of a blade for cutting the capsule, and also a line of weakness consisting of a thinned peripheral zone situated in the bottom of the said groove. The invention also relates to the method of producing this capsule which is used for any closure of a bottle which has to have its capsule removed by means of a knife.
