The method enables a closure and security device (22) comprising a screw stopper (l0A) and a security capsule (16A) to be formed and applied to a container (20) provided with an externally threaded circular mouth. The method consists of: connecting to a screw stopper (10), or to a stopper destined to become a screw stopper once applied to the container (20), a capsule forming foil (12) in such a .manner as to provide the stopper (10) with a skirt (16) projecting by a determined portion from the free edge of the stopper (10), to obtain -a-stopper-skirt combination,(1~8; 18A; 18B); applying the stopper- skirt combination (18; 18A; 18B) to the mouth of the relative container (20); and making the skirt (16) rigid with the container (20) by known capsule techniques, depending on the type of foil used, so as to obtain a stopper- capsule (22). The closure and security device (22) comprises a screw stopper ( l0A), and a capsule (16A) which is rigid both with the screw stopper (10A) and with the adjacent part of the outer surface of the container (20). The capsule (16A) comprises means (24) which enable it to be torn as a result of or prior to the unscrewing of the screw stopper).

La présente invention concerne un procédé permettant de former un dispositif (22) de sécurité et de fermeture comprenant un stoppeur à vis (10A) et une capsule de sécurité (16A), et de l'appliquer à un contenant (20) présentant un goulot circulaire fileté à l'extérieur. Le procédé consiste à raccorder à un stoppeur à vis (10), ou à un stoppeur destiné à servir de stoppeur à vis après application sur le contenant (20), une feuille de formation de capsule (12) de manière à obtenir un stoppeur (10) doté d'une jupe (16) en saillie sur une portion déterminée depuis le bord libre du stoppeur (10), afin d'obtenir un ensemble stoppeur-jupe (1-8; 18A; 18B); à appliquer l'ensemble stoppeur-jupe (18; 18A; 18B) au goulot du contenant relatif (20); puis à rigidifier la jupe (16) avec le contenant (20) par des techniques de capsulage connues en fonction du type de feuille utilisé, afin d'obtenir un bouchon stoppeur (22). Le dispositif (22) comprend un stoppeur à vis (10A), et une capsule (16A) qui est rigide à la fois avec le stoppeur à vis (10A) et avec la partie adjacente de la surface extérieure du contenant (20). La capsule (16A) comprend un moyen (24) qui lui permet d'être tournée avec ou avant le dévissage du stoppeur à vis (10A).
