Abstract

Le problème décrit par la présente invention est de permettre la réduction des coûts de fabrication, par rapport aux outils de décharge des documents de brevet 1 et 2, d'une unité de buse (3) pour décharger simultanément deux sortes de contenus à partir d'une première tige (42) et d'une seconde tige (43) qui sont disposées adjacentes l'une à l'autre dans la direction radiale sur un côté d'extrémité d'un bombe aérosol cylindrique (2) ; et de permettre qu'une opération de détachement de composant accompagnant un processus de nettoyage de passage pour décharger des contenus soit effectuée simplement pour l'unité de buse (3). La solution selon l'invention porte sur une unité de buse (3) qui est composée des deux composants d'une base (5) et d'une tête de décharge (6). La tête de décharge (6) comprend une buse (61) et une partie de cadre (62). La buse (61) est reliée à chacune de la première tige (42) et de la seconde tige (43), et fusionne les contenus, respectivement déchargés de la première tige (42) et de la seconde tige (43), pour ainsi décharger le contenu vers l'extérieur. La partie de cadre (62) a une section de verrouillage (62e) verrouillée de façon détachable à la base (5), répond à une opération de pression de la buse (61), et supporte la buse (61) de telle sorte que la buse peut être inclinée. La base (5) a une partie verrouillée (52a) à laquelle la section de verrouillage (62e) de la tête de décharge (6) est verrouillée.
