The container comprises a container body (1) and a sealing cap (9) which may be screwed to the container body (1). Barbs (5) are circularly distributed on the container body (1). Said barbs (5) each comprise a run-up ramp (7) and a locking surface (8). The sealing cap (9) is connected to a security ring (16) by means of break-off webs (15). The security ring (16) comprises projections (17) extending inwards from the inner circumference thereof, with run-up ramps (18) and locking surfaces (19). On closing the sealing cap (9) the run-up ramps (7;18) slide over each other. On unscrewing the sealing cap (9) an opposing blocking occurs due to the locking surfaces (8;19). The security ring (16) is thus blocked relative to the sealing cap (9), whereupon the break-off webs (15) are torn off.

La présente invention concerne un récipient comprenant un corps de récipient (1) et un bouchon de fermeture (9) pouvant être vissé sur le corps de récipient (1). Sur le corps de récipient (1) sont disposés des crans (5) répartis de façon circulaire. Ces crans (5) présentent respectivement une surface inclinée (7) et une surface de verrouillage (8). Le bouchon de fermeture (9) est relié à un anneau de sécurité (16) par des brides de rupture (15). L'anneau de sécurité (16) présente des éléments en saillie (17) dépassant de sa périphérie intérieure vers l'intérieur dotés de surfaces inclinées (18) et de surfaces de verrouillage (19). Au cours de la fermeture du bouchon de fermeture (9), les surfaces inclinées (7; 18) coulissent l'une sur l'autre. Au cours de l'ouverture du bouchon de fermeture (9), les surfaces de verrouillage (8; 19) provoquent un blocage mutuel. Ainsi, l'anneau de sécurité (16) est bloqué par rapport au bouchon de fermeture (9), ce qui provoque la rupture des brides de rupture (15).
