A liquid dispenser assembly (10) for personal hygiene liquids includes a container (14) and a dispenser valve (16). Each valve includes a valve plunger (60) with a head (62) having a flexible peripheral skirt (64) that provides increased bypass of liquid upon harder pressing and faster motion of the plunger. The valve (16) has an annular seat (85) that has a tapered seat surface (88) that presses the flexible skirt (64) against the valve inner cylindrical wall (54) of the valve bore (52) at the end of the return stroke.

Cette invention se rapporte à un ensemble distributeur de liquide (10) conçu pour des liquides d'hygiène personnelle et doté d'un contenant (14) et d'un clapet distributeur (16). Chaque clapet comporte un piston plongeur (60) doté d'une tête (62) possédant une jupe (64) périphérique souple qui assure une dérivation accrue du liquide lors d'une compression plus forte et d'un mouvement plus rapide du piston plongeur. Le clapet (16) possède un siège annulaire (85) présentant une surface (88) conique qui comprime la jupe souple (64) contre la paroi (54) cylindrique interne de l'alésage (52) du clapet à la fin de la course retour.
