Abstract

La présente invention concerne un récipient de distribution de mousse qui est approprié aussi bien pour la prévention de l'égouttement que pour la distribution stable de mousse d'une qualité préférable. Le récipient de distribution de mousse comporte : un corps de récipient ; un capuchon (2) destiné à être fixé à une ouverture du corps de récipient ; et une soupape (3) destinée à ouvrir et à fermer un canal d'écoulement dans le capuchon (2). Le capuchon (2) possède : un canal d'écoulement de matériau liquide (F1) qui fournit un passage destiné à un matériau liquide au sein du corps de récipient ; un canal d'écoulement d'air (F2) qui fournit un passage destiné à l'air au sein du corps de récipient ; une chambre de mélange (F3) qui est reliée aux deux types de canaux d'écoulement (F1, F2) pendant que la soupape (3) est dans un état ouvert ; et une ouverture de capuchon (F4) qui est reliée à l'extérieur du récipient. La soupape (3) comprend : une bague fixe cylindrique (32) qui est fixée au capuchon (2) à une position qui entoure les sorties respectives des deux types de canaux d'écoulement ; et une soupape interne (34) qui est formée à l'intérieur de la bague fixe (32) et qui est élastiquement déformable et apte à ouvrir/fermer simultanément les sorties respectives des deux types de canaux d'écoulement (F1, F2). La soupape interne (34), dans un état fermé, est une membrane qui est formée de façon à se trouver à partir de la partie cylindrique de la bague fixe (32) vers un axe central de cette dernière et simultanément à être inclinée vers le côté corps de récipient.
