Abstract

The actuator consists of a disc (1) with a central dome (2) which has a cylindrical axial duct (3) through it leading to an outlet (4), and a shoulder (6) to press against the upper end of the hollow valve stem (7). The valve is actuated when the disc is depressed, which is achieved by a hinged plate (16) which folds over the top of the disc and is equipped with a trigger which engages with and depresses the disc. Both the disc and plate are able to pivot on film hinges.

Description

La présente invention est relative à un dispositif d'actionnement de valve de distribution de bidon aérosol, et plus précisément un dispositif permettant d'assurer un déplacement de la tige creuse de manoeuvre d'une valve de distribution d'un bidon aérosol, et ce, pour toutes les positions possibles du bidon.The present invention relates to a device for actuating an aerosol can dispensing valve, and more specifically a device making it possible to move the hollow operating rod of a dispensing valve for an aerosol can, and this , for all possible positions of the container.

Pour la distribution dosée de nombreux produits conditionnés en aérosols, notamment des produits cosmétiques, il est souhaitable de pouvoir actionner la valve du bidon aérosol que celui-ci soit en position "tête en haut" dans laquelle la tige de manoeuvre de la valve de distribution se trouve inclinée ou verticale, dirigée vers le haut, ou en position "tête en bas", dans laquelle la tige de manoeuvre de la valve de distribution se trouve inclinée ou verticale, dirigée vers le bas.For the metered distribution of many products packaged in aerosols, in particular cosmetic products, it is desirable to be able to actuate the valve of the aerosol can that the latter is in the "head up" position in which the operating rod of the dispensing valve is inclined or vertical, directed upwards, or in the "upside down" position, in which the operating rod of the dispensing valve is inclined or vertical, directed downwards.

Une telle double possibilité d'utilisation d'un bidon aérosol existe en particulier dans le cas où le bidon aérosol est amené à contenir un colorant destiné à être mélangé juste avant l'emploi avec un oxydant pour former un produit de coloration à appliquer sur les cheveux.Such a double possibility of using an aerosol can exists in particular in the case where the aerosol can is made to contain a dye intended to be mixed just before use with an oxidant to form a coloring product to be applied to the hair.

Le mélange du colorant et de l'oxydant juste avant l'emploi peut s'effectuer à l'abri de l'air dans un récipient fermé de mélange muni de moyens d'application, tel que décrit par exemple dans la demande de brevet français 93 15442 de la société déposante, ou, de manière plus conventionnelle, dans un bol de mélange à partir duquel le produit de coloration est appliqué sur les cheveux par un moyen d'application séparé.The mixing of the dye and the oxidant just before use can be carried out in the absence of air in a closed mixing container provided with application means, as described for example in the French patent application. 93 15442 from the applicant company, or, more conventionally, in a mixing bowl from which the coloring product is applied to the hair by a separate application means.

Dans le cas de l'utilisation d'un récipient de mélange fermé, tel que décrit dans la demande de brevet antérieure précitée, le colorant contenu dans un bidon aérosol est introduit de bas en haut dans le récipient de mélange par l'intermédiaire d'une ouverture située dans le fond du récipient de mélange et munie d'une valve, notamment de type membrane, à fermeture automatique.In the case of the use of a closed mixing container, as described in the aforementioned prior patent application, the dye contained in an aerosol can is introduced from bottom to top into the mixing container by means of an opening located in the bottom of the mixing container and provided with a valve, in particular of the membrane type, with automatic closure.

Le bidon aérosol est à cet effet muni d'un embout apte à coopérer avec la paroi de fond du récipient de mélange pour provoquer l'actionnement de la tige de manoeuvre de la valve de distribution du bidon aérosol.The aerosol can is for this purpose provided with a nozzle capable of cooperating with the bottom wall of the mixing container to cause actuation of the actuating rod of the aerosol canister distribution valve.

L'embout comporte une plaquette, en forme de disque, munie d'une protubérance centrale en forme de dôme comportant intérieurement un conduit axial cylindrique débouchant dans un orifice de sortie à la partie supérieure de ladite protubérance, et une cavité intérieure en communication avec ledit conduit et comportant au moins une portée en décrochement agencée de manière telle que, lorsqu'une tige creuse de manoeuvre d'une valve de distribution d'un bidon aérosol est introduite dans le conduit cylindrique, ladite portée en décrochement constitue une butée permettant un déplacement relatif de la tige de manoeuvre par rapport au corps du bidon aérosol et l'expulsion du produit contenu dans le bidon aérosol au travers de l'orifice de sortie.The endpiece comprises a plate, in the form of a disc, provided with a central dome-shaped protuberance, internally comprising a cylindrical axial duct opening into an outlet orifice at the top of said protuberance, and an interior cavity in communication with said duct and comprising at least one recessing surface arranged in such a way that, when a hollow operating rod of a valve for dispensing an aerosol can is introduced into the cylindrical conduit, said recessing surface constitutes a stop allowing movement relative of the operating rod relative to the body of the aerosol can and the expulsion of the product contained in the aerosol can through the outlet.

Il est ainsi possible d'assurer une distribution du produit contenu dans le bidon aérosol lorsque celui-ci est disposé "tête en haut", l'actionnement de la tige de manoeuvre de la valve du bidon aérosol s'effectuant par suite d'un mouvement axial relatif du bidon aérosol et du récipient muni à sa base de l'ouverture de remplissage.It is thus possible to ensure a distribution of the product contained in the aerosol can when it is placed "head up", the actuation of the actuating rod of the valve of the aerosol can being effected by a relative axial movement of the aerosol can and the container provided at its base with the filling opening.

Or, de nombreux utilisateurs souhaitent pouvoir préparer des produits de coloration à l'aide d'un colorant contenu dans un bidon aérosol en ayant la possibilité d'utiliser aussi bien un récipient fermé de mélange qu'un bol ouvert traditionnel.However, many users wish to be able to prepare coloring products using a dye contained in an aerosol can by having the possibility of using both a closed mixing container and a traditional open bowl.

Dans ce cas, l'embout de raccordement, tel que décrit plus haut, ne permet pas un actionnement simple et fiable de la tige de manoeuvre de la valve de distribution du bidon aérosol pour toute position "tête en bas" de celui-ci.In this case, the connecting piece, as described above, does not allow simple and reliable actuation of the operating rod of the dispensing valve of the aerosol can for any "upside down" position thereof.

La présente invention a précisément pour objet de proposer un dispositif d'actionnement qui, tout en présentant les caractéristiques mentionnées plus haut d'un embout de raccordement pour assurer un actionnement de la valve de distribution du bidon aérosol en position "tête en haut", permet un actionnement facile et fiable de la valve de distribution pour toute autre position du bidon aérosol.The object of the present invention is precisely to propose an actuating device which, while having the characteristics mentioned above of a connection nozzle for ensuring actuation of the dispensing valve of the aerosol can in the "head up" position, allows easy and reliable actuation of the dispensing valve for any other position of the aerosol can.

Le dispositif selon la présente invention qui comporte une plaquette en forme de disque munie d'une protubérance centrale, notamment en forme de dôme, telle que décrite ci-dessus, se caractérise essentiellement par le fait que ladite plaquette est disposée transversalement dans une frette cylindrique apte à être fixée sur une collerette supérieure du bidon aérosol, et reliée à sa périphérie à ladite frette cylindrique par des moyens de liaison, tels que des charnières-films, permettant un déplacement de la plaquette par rapport à ladite frette fixée au bidon aérosol, et qu'il est prévu un mécanisme à levier, pour l'actionnement manuel dudit dispositif, comportant une patte d'actionnement en saillie vers le haut d'un bord périphérique de ladite plaquette et une butée disposée au-dessus du bord périphérique de ladite plaquette, en un emplacement diamétralement opposé à ladite patte d'actionnement.The device according to the present invention which comprises a disc-shaped plate provided with a central protuberance, in particular in the form of a dome, as described above, is essentially characterized by the fact that said plate is arranged transversely in a cylindrical hoop capable of being fixed on an upper flange of the aerosol can, and connected at its periphery to said cylindrical hoop by connecting means, such as film hinges, allowing a displacement of the plate relative to said hoop fixed to the aerosol can, and that a lever mechanism is provided, for manual actuation of said device, comprising an actuating tab projecting upwards from a peripheral edge of said wafer and a stop disposed above the peripheral edge of said wafer, at a location diametrically opposite to said actuating tab.

Dans un mode de réalisation préféré, permettant la réalisation du dispositif selon l'invention d'un seul tenant, notamment par moulage de matière plastique, la patte d'actionnement et la butée sont réalisées, diamétralement opposées, sur un anneau dont le diamètre intérieur est légèrement inférieur au diamètre extérieur de ladite plaquette, ledit anneau étant relié à ladite frette par une partie de liaison articulée permettant à l'anneau d'être amené au-dessus de la plaquette, des moyens, tels que des moyens d'encliquetage coopérants, étant en outre prévus pour fixer l'anneau sur la plaquette, de préférence au voisinage immédiat de son bord périphérique.In a preferred embodiment, allowing the device according to the invention to be produced in one piece, in particular by molding of plastic material, the actuating tab and the stop are produced, diametrically opposite, on a ring whose internal diameter is slightly smaller than the outside diameter of said plate, said ring being connected to said hoop by an articulated connecting part allowing the ring to be brought above the plate, means, such as cooperating latching means , being further provided for fixing the ring on the wafer, preferably in the immediate vicinity of its peripheral edge.

La patte d'actionnement présente avantageusement une section en forme de L dont la branche horizontale, supérieure, constitue une zone d'appui pour le doigt de l'utilisateur.The actuating tab advantageously has an L-shaped section, the upper horizontal branch of which constitutes a support zone for the user's finger.

La butée est de préférence réalisée par une branche d'une languette rigide, de section en L, reliant l'anneau à la partie de liaison de celui-ci avec la frette cylindrique.The stop is preferably made by a branch of a rigid tongue, L-shaped section, connecting the ring to the connecting portion thereof with the cylindrical hoop.

  • Figure 6 is a view illustrating the actuation of the device according to the invention in the "upside down" position of the aerosol can.

On se réfère tout d'abord aux figures 1 à 3.We first refer to Figures 1 to 3.

Le dispositif selon l'invention comporte une plaquette en forme de disque 1, munie centralement d'une protubérance en forme de dôme. La protubérance 2 comporte intérieurement un conduit axial cylindrique 3 débouchant dans un orifice de sortie 4 à sa partie supérieure. La protubérance 2 comporte également une cavité intérieure 5 en communication avec le conduit 3 et présentant une portée en décrochement 6. La portée en décrochement 6 est destinée à constituer une butée pour la tige de manoeuvre 7 d'une valve de distribution (non représentée) d'un bidon aérosol 8 muni d'une collerette supérieure 9.The device according to the invention comprises a disc-shaped plate 1, provided centrally with a dome-shaped protuberance. The protrusion 2 internally comprises a cylindrical axial conduit 3 opening into an outlet orifice 4 at its upper part. The protrusion 2 also includes an interior cavity 5 in communication with the conduit 3 and having a recessed bearing surface 6. The recessed bearing surface 6 is intended to constitute a stop for the operating rod 7 of a distribution valve (not shown) an aerosol can 8 provided with an upper flange 9.

La plaquette en forme de disque 1 est reliée à sa périphérie par des ponts de matière 10, constituant des charnières-films, à une frette cylindrique 11 apte à être solidarisée de la collerette 9 du bidon aérosol 8.The disc-shaped plate 1 is connected at its periphery by bridges of material 10, constituting film hinges, to a cylindrical hoop 11 capable of being secured to the collar 9 of the aerosol can 8.

Dans l'exemple illustré, la frette cylindrique 11 est constituée de deux jupes cylindriques réunies par une portée en décrochement 12.In the example illustrated, the cylindrical hoop 11 consists of two cylindrical skirts joined by a recessed bearing 12.

Au niveau de sa portée en décrochement 12, la jupe cylindrique 11 est réunie par une zone d'épaisseur réduite 13 à une branche 14 d'une languette en forme de L, 15, dont l'autre branche 16 est solidaire d'un anneau 17 que l'on voit le mieux sur la figure 3.At its recessed bearing surface 12, the cylindrical skirt 11 is joined by a zone of reduced thickness 13 to a branch 14 of an L-shaped tongue, 15, the other branch 16 of which is integral with a ring 17 which is best seen in FIG. 3.

L'anneau 17 présente un diamètre intérieur légèrement inférieur au diamètre extérieur de la plaquette 1.The ring 17 has an inside diameter slightly smaller than the outside diameter of the wafer 1.

L'anneau 17 comporte, en un emplacement diamétralement opposé à la languette 15, une patte d'actionnement de section en L, 18, dont la branche horizontale supérieure 19 constitue, comme cela sera expliqué plus loin, une surface d'appui pour le doigt d'un utilisateur.The ring 17 comprises, at a location diametrically opposite the tongue 15, an L-shaped actuation tab, 18, whose upper horizontal branch 19 constitutes, as will be explained below, a bearing surface for the finger of a user.

L'autre branche de la patte 18 comporte à son extrémité un téton en saillie 20 conçu pour s'engager dans un orifice de retenue 21 ménagé dans la plaquette 1 au voisinage de son bord périphérique.The other branch of the tab 18 has at its end a protruding stud 20 designed to engage in a retaining orifice 21 formed in the plate 1 in the vicinity of its peripheral edge.

Le dispositif selon l'invention peut être réalisé d'un seul tenant par moulage de matière plastique, notamment de polypropylène.The device according to the invention can be produced in one piece by molding plastic material, in particular polypropylene.

Le montage du dispositif, tel qu'illustré à la figure 2 sur un bidon aérosol, s'effectue par mise en place de la jupe cylindrique 11 sur la collerette supérieure 9 du bidon aérosol 8 jusqu'à atteindre la position illustrée à la figure 1, après quoi, on rabat l'ensemble constitué par la languette 15, l'anneau 17 et la patte 18 autour de la charnière constituée par la zone d'épaisseur réduite 13 jusqu'à la position illustrée à la figure 1 dans laquelle la solidarisation de l'ensemble avec la plaquette 1 s'effectue par engagement du téton 20 dans l'orifice correspondant 21.The device, as illustrated in FIG. 2, is mounted on an aerosol canister, by placing the cylindrical skirt 11 on the upper flange 9 of the aerosol can 8 until reaching the position illustrated in FIG. 1 , after which, the assembly consisting of the tongue 15, the ring 17 and the tab 18 is folded around the hinge formed by the zone of reduced thickness 13 up to the position illustrated in FIG. 1 in which the connection of the assembly with the plate 1 is effected by engagement of the stud 20 in the corresponding orifice 21.

On se réfère maintenant aux figures 4 et 5.We now refer to Figures 4 and 5.

Lorsque le dispositif doit être actionné en position "tête en haut" du bidon aérosol 8, notamment pour assurer le remplissage d'un récipient, tel qu'illustré à la figure 5 et décrit plus en détail dans la demande de brevet français 93 15442 de la société déposante, le déplacement de la tige de manoeuvre 7 de la valve de distribution du bidon aérosol 8 s'effectue en exerçant un appui vertical sur le disque 1, comme illustré par les flèches de la figure 4.When the device must be actuated in the "head up" position of the aerosol can 8, in particular to fill a container, as illustrated in FIG. 5 and described in more detail in French patent application 93 15442 of the applicant company, the movement of the operating rod 7 of the dispensing valve of the aerosol can 8 is effected by exerting a vertical support on the disc 1, as illustrated by the arrows in FIG. 4.

Ce déplacement peut être assuré par appui sur le disque 1 d'une portée annulaire 22 en saillie du fond du récipient à remplir. Cette portée annulaire 22 traverse l'anneau 17 et vient en appui sur la plaquette dont le déplacement provoque un déplacement axial de la tige de manoeuvre 7.This movement can be ensured by pressing on the disc 1 of an annular surface 22 projecting from the bottom of the container to be filled. This annular bearing surface 22 passes through the ring 17 and comes to bear on the plate, the displacement of which causes an axial displacement of the operating rod 7.

On se réfère maintenant à la figure 6.We now refer to Figure 6.

Pour un actionnement du dispositif selon l'invention en position "tête en bas" du bidon aérosol 8, on exerce un appui sur la branche 19 de la patte 18 dans le sens de la flèche illustrée à la figure 6, cet appui, combiné avec un contre-appui de butée diamétralement opposé du bord périphérique de la plaquette 1 sur la branche 16 de la languette 15, provoquant un déplacement, par effet de levier, de la plaquette 1 et de la protubérance 2 située sur elle, entraînant un déplacement légèrement dévié mais néanmoins suffisant de la tige de manoeuvre 7 pour actionner la valve.For actuation of the device according to the invention in the "upside down" position of the aerosol can 8, a support is exerted on the branch 19 of the lug 18 in the direction of the arrow illustrated in FIG. 6, this support, combined with a diametrically opposite abutment abutment from the peripheral edge of the wafer 1 on the branch 16 of the tongue 15, causing a displacement, by leverage, of the plate 1 and the protuberance 2 located thereon, causing a slightly deflected but nevertheless sufficient displacement of the operating rod 7 to actuate the valve.
