Un contenant destiné à distribuer des liquides comprend un élément formant corps (2) et une fermeture (6) destinée à l'élément formant corps (2), ladite fermeture (6) comportant un bouchon (8) se présentant sous forme d'un moulage en plastique doté d'une sortie (12) et d'un distributeur (22) à diaphragme situés dans le bouchon (8), ledit distributeur (22) à diaphragme étant un moulage en plastique monobloc présentant une partie (26) de diaphragme et une partie (28) de nez, cette dernière (28) fermant normalement la sortie (12), mais pouvant se déplacer par rapport à cette dernière lorsque la partie (28) de diaphragme se déforme sous l'effet de la pressurisation de l'intérieur de l'élément formant corps (2), le liquide étant alors distribué par la sortie (12). Le bouchon (8) comprend en outre un siège annulaire (20) destiné au distributeur (22) à diaphragme qui est creux, ouvert au niveau terminal, de forme globalement cylindrique et dont le diamètre (D) est sensiblement égal à celui de la partie (26) de diaphragme du distributeur (22).
