The invention concerns a safety screw cap closure device for a container provided with an outer screw thread opening, which consists of two interlocked coaxial caps, the outer one capable of driving the inner one by axial pressure and rotation: the outer cap (1) including, on the inner surface of one of its walls, snap-on means; the inner cap (40) comprising a screw thread on the inner surface of its cylindrical side wall (2) and snap-on means on the outer surface of its wall, opposite the inner cap wall (40) including the snap-on means, and elastic means for disengaging the snap-on means of the walls of both the inner and outer caps located between the upper end walls (3) of the two caps, and made of a material of different compositions from the composition of the caps.
Dispositif de fermeture de sécurité par vissage d'un conteneur muni d'une ouverture à filet de vis externe, qui se compose de deux bouchons coaxiaux, emboîtés l'un dans l'autre, l'un externe pouvant entraîner l'autre interne par pression axiale et rotation: le bouchon externe (1) comportant, sur la surface interne de l'une de ses parois, des moyens d'encliquetage; le bouchon interne (40) comportant un filet de vis sur la surface interne de sa paroi latérale cylindrique (2) et des moyens d'encliquetage sur la surface externe de sa paroi, en regard de la paroi du bouchon interne (40) comportant les moyens d'encliquetage; et un moyen élastique désaccouplant les moyens d'encliquetage des parois des deux bouchons interne et externe placés entre les parois d'extrémité supérieure (3) des deux bouchons, et réalisé dans un matériau de compositions différente de la composition des bouchons.
