Title
(EN) TWO-COMPONENT AEROSOL CAN
(FR) BOMBE A AEROSOL A DEUX ELEMENTS
Abstract
(EN)
A two-component aerosol can comprises an outer container (1) for receiving a first component and a propellant, an inner container (17) for receiving a second component as well as a valve (6, 7), which comprises a valve pipe (6) extending through a hole in the top cover (2) of the container (1), said valve pipe comprising an outwardly open channel (21) and being tiltably and rotatably connected to the rim of the hole (5) by means of a surrounding sealing plug (7). Adjacent the inner end of the sealing plug (7), the valve pipe (6) comprises a plurality of holes (20) extending through the wall of the valve pipe and into the inner channel thereof. In the non-activated state of the valve pipe (6), the holes (20) are sealingly closed by the sealing plug (7), whereas they are uncovered at least partially so as to allow a free passage therethrough in the tilted state of said valve pipe (6). A coupling member (14) is provided at the inner end of the valve pipe (6), said coupling member (14) comprising an outer thread (15) co-operating with an inner thread (16) shaped at the top of the inner container (17) in such a manner that the said inner container (17) can be connected to the valve pipe (6). The sealing plug (7) comprises furthermore guide means (11-13) co-operating with mating engaging means (23-25) on the inner container (17) in such a manner that the inner container (17) is prevented from rotating while the valve pipe (6) is turned so as to disengage said inner container (17) from its connection with the valve pipe (6).
(FR)
Une bombe à aérosol à deux éléments comporte un récipient externe (1), destiné à loger un premier élément et un propulseur, ainsi qu'un récipient interne (17), destiné à loger un second élément ainsi qu'une soupape (6, 7), laquelle comporte un conduit de soupape (6) traversant un trou ménagé dans le couvercle supérieur (2) du récipient externe (1), ce conduit de soupape comprenant un canal à ouverture sur l'extérieur (21) et étant monté, de façon à pouvoir être incliné et tourné, sur le bord du trou (5) au moyen d'un obturateur enveloppant d'étanchéité (7). Au voisinage de l'extrémité interne de l'obturateur d'étanchéité (7), le conduit de soupape (6) comporte plusieurs trous (20) traversant la paroi du conduit de soupape et s'étendant dans son canal interne. Lorsque le conduit de soupape (6) n'est pas utilisé, les trous sont hermétiquement fermés par l'obturateur d'étanchéité (7) alors qu'ils sont au moins partiellement à découvert, de manière à laisser un passage libre entre eux, lorsque ledit conduit de soupape (6) se trouve incliné. L'extrémité interne du conduit de soupape (6) porte un élément de raccordement (14) comprenant un filetage extérieur (15) coopérant avec un filetage intérieur (16) formé au sommet du récipient interne (17) de sorte que ce récipient (17) puisse être raccordé au conduit de soupape (6). L'obturateur d'étanchéité (7) comporte, de surcroît, un mécanisme de guidage (11, 13) coopérant avec des organes de raccordement (23, 25) sur le récipient interne (17) de façon à ce que celui-ci ne puisse pas effectuer de rotation alors que le conduit de soupape (6) est tourné de manière à désolidariser ledit récipient interne (17) de son raccordement avec le conduit de soupape (6).
