Abstract

La présente invention concerne un récipient qui est rempli de liquide, fermé de manière étanche et à partir duquel il est possible de prélever du liquide. Ce récipient présente un élément d'insertion qui peut être fixé dans une ouverture du récipient de manière à assurer une étanchéité. Cet élément d'insertion présente une cartouche de CO2 sous haute pression (14), une soupape de régulation de pression, conçue pour délivrer du CO2, ainsi qu'un organe de réglage qui est accessible depuis l'extérieur et qui permet de percer la cartouche de CO2 sous haute pression (14) lorsqu'il est actionné. En cas d'augmentation de pression indésirable dans le récipient, une sécurité anti-surpression libère une voie d'écoulement depuis son espace de tête, à travers l'élément d'insertion, et jusque dans l'atmosphère. Cette sécurité anti-surpression est conçue sous forme de sécurité à éclatement. Elle éclate en cas de dépassement d'une pression interne à laquelle le récipient est visiblement bombé, mais avant que cette pression interne ne fasse exploser le récipient.
