A closing valve for a container comprises a closing jacket connected therewith, which closing jacket is provided on the inside with a narrowed and a widened portion, and a valve part movable in this closing jacket. This valve part has a closing element and a clamping element which is provided on at least the outside with a thickening which, when the passage through the closing jacket is sealed by the valve part, cooperates with the widened portion in the closing jacket. Furthermore, a head part movable in the closing jacket back and forth is provided, by means of which the valve part can be moved with respect to the closing jacket such that the passage therethrough can be released and/or closed, while when releasing the passage through the closing jacket, the thickening on the outside of the clamping element is brought into the narrowed portion of the closing jacket, as a result of which the clamping element reaches a position in which it is engaged by the head part.

La présente invention concerne une valve de fermeture d'un contenant comprenant un embout de fermeture, qui lui est relié, dont l'intérieur présente des parties rétrécies et élargies et un ensemble valve, mobile à l'intérieur de cet embout. Cet ensemble valve possède un élément de fermeture et un élément de serrage monté au moins sur l'extérieur avec un épaississement qui, lorsque le passage à travers l'embout de fermeture est obturé par l'ensemble valve, coopère avec la portion élargie de l'embout de fermeture. En outre, une tête, mobile en va-et-vient à l'intérieur de l'embout de fermeture, permet de déplacer l'ensemble valve par rapport à l'embout de fermeture de telle manière que le passage existant puisse être ouvert et/ou fermé. Lorsque ce passage se trouve en position ouverte, l'épaississement situé sur l'extérieur de l'élément de serrage est amené dans la portion rétrécie de l'embout de fermeture, ce qui pour résultat d'amener l'élément de serrage dans une position où la tête s'engage avec lui.
