Abstract

Selon l'invention, il est possible d'assembler facilement une unité de soupape et un contenant, de les réutiliser, et de les fabriquer à bas coût, selon un procédé consistant à introduire par coulissement un élément de piston (3), en forme de tuyau, dans un corps de soupape en forme de tuyau (2), que l'on insère à son tour dans un corps de contenant (Y) pour l'y monter de manière amovible. Un soufflet (19) du type accordéon, faisant communiquer l'intérieur de l'élément de piston (3) avec une partie ouvrante (13) et pouvant revenir dans son sens d'extension, est relié entre l'extrémité d'insertion de l'élément de piston (3), et la partie d'ouverture (13).
