L'utilisation d'un jet de gaz vecteur pour pulvériser une peinture est connue depuis longtemps, notamment par le brevet US 2,635,921 .The use of a vector gas jet for spraying a paint has been known for a long time, in particular by means of the patent US 2,635,921 .

Ce principe a été développé et a fait l'objet de nombreux dépôts de brevets.This principle has been developed and has been the subject of numerous patent filings.

A titre indicatif, on peut citer la demande de brevet européen EP-A1-0 208 247 ou les brevets US 5 954 273 , correspondent au préambule de la revendication indépendante, US 5,255,852 et US 5,713,519 . Dans ce dernier, le gaz vecteur alimente deux tuyères et deux liquides différents sont injectés dans les tuyères pour se mélanger à l'extérieur du dispositif, lors de la rencontre des jets émis par les tuyères.As an indication, mention may be made of the request for European patent EP-A1-0 208 247 where the US Patents 5,954,273 , correspond to the preamble of the independent claim, US5,255,852 and US 5,713,519 . In the latter, the carrier gas feeds two nozzles and two different liquids are injected into the nozzles to mix on the outside of the device, when the jets emitted by the nozzles meet.

Par ailleurs, on connaît par la demande de brevet français FR-A-2 781 208 un dispositif autonome pour la pulvérisation sur un support d'une composition choisie parmi une pluralité de compositions ayant des teintes différentes, dans lequel le produit est pulvérisé grâce à une dépression provoquée par la détente d'un jet de gaz vecteur à proximité d'un organe d'amenée du produit, le jet de gaz vecteur étant émis par une buse dont l'axe est contenu dans le même plan que celui de l'organe d'amenée.Moreover, we know by the request of French patent FR-A-2 781 208 an autonomous device for spraying a support of a composition selected from a plurality of compositions having different hues, wherein the product is sprayed by a depression caused by expansion of a vector gas jet near a product delivery member, the vector gas jet being emitted by a nozzle whose axis is contained in the same plane as that of the delivery member.

On trouve également sur le marché sous la marque Ecospray ® des dispositifs de pulvérisation qui conviennent pour l'application d'une peinture sur un support non kératinique mais qui, dans le cas d'une utilisation en cosmétique, ne permettent pas d'obtenir des résultats satisfaisants.Also available on the market under the trademark Ecospray ® are spraying devices which are suitable for the application of a paint on a non-keratinous support but which, in the case of use in cosmetics, do not make it possible to obtain satisfactory results.

On connaît encore par le brevet US 1 430 506 un dispositif comportant un réservoir sur lequel sont fixées deux buses reliées à une arrivée d'air comprimé, ces deux buses pouvant émettre des jets d'air se rencontrant dans une région située au-dessus d'un orifice d'amenée du produit. Un tel dispositif requiert une source extérieure d'air comprimé et ne constitue pas un dispositif autonome.We still know by the U.S. Patent 1,430,506 a device comprising a reservoir on which are fixed two nozzles connected to a compressed air inlet, these two nozzles can emit air jets meeting in a region located above a product supply port. Such a device requires an external source of compressed air and does not constitute an autonomous device.

Il est connu par ailleurs d'appliquer un produit de maquillage au moyen d'un aérographe encore appelé « air-brush », comportant un stylo pulvérisateur relié à une bouteille d'un gaz vecteur comprimé, ce stylo pulvérisateur comprenant d'une part une tuyère d'éjection du gaz vecteur et d'autre part une coupelle dans laquelle le produit à pulvériser est contenu, ce produit étant progressivement aspiré par un conduit dans la coupelle grâce à la dépression créée par effet Venturi par la vitesse du gaz vecteur à sa sortie de la tuyère. La pulvérisation de type air-brush permet notamment de rendre moins visible la frontière entre les zones traitées et non traitées, de réaliser des fondus, des dégradés ou des impressions de volume. La gestuelle est également différente, puisque le produit qui est pulvérisé n'a pas à être étalé une fois déposé sur le support kératinique. L'application du produit est ainsi très hygiénique, puisqu'elle peut se faire sans les doigts et sans applicateur.It is also known to apply a make-up product by means of an airbrush, also called an "air-brush", comprising a spray pen connected to a bottle of a compressed carrier gas, this spray pen comprising on the one hand a nozzle of the vector gas ejection and secondly a cup in which the product to be sprayed is contained, this product being progressively sucked by a conduit into the cup thanks to the depression created by the Venturi effect by the speed of the carrier gas at its outlet of the nozzle. Air-brush type spraying makes it possible, in particular, to make the boundary between the treated and untreated zones less visible, to perform fades, gradients or volume impressions. The gesture is also different, since the product that is sprayed does not have to be spread once deposited on the keratin support. The application of the product is thus very hygienic, since it can be done without fingers and without applicator.

Un dispositif tel que décrit ci-dessus fait l'objet par exemple de la demande de brevet canadien CA-A-2 152 406 . Des dispositifs similaires sont commercialisés par la société DINAIR, sous les marques déposées BEAUTY ART ou BODY ART, la bouteille de gaz vecteur comprimé étant remplacée par un compresseur à air. Ces dispositifs connus, dans lesquels le stylo pulvérisateur et la source de gaz vecteur ne constituent pas une construction unitaire, étant reliés par un flexible, sont relativement encombrants et sont destinés principalement à un usage professionnel. Ils ne conviennent pas pour être transportés aisément par une femme dans son sac à main, à l'instar des accessoires de maquillage conventionnels.A device as described above is the subject, for example, of the Canadian patent application CA-A-2,152,406 . Similar devices are marketed by DINAIR under the registered trademarks BEAUTY ART or BODY ART, the bottle of compressed carrier gas being replaced by an air compressor. These known devices, in which the spray pen and the carrier gas source do not constitute a unitary construction, being connected by a hose, are relatively bulky and are intended primarily for professional use. They are not suitable for being carried easily by a woman in her purse, like conventional makeup accessories.

La présente invention a pour objet un nouveau dispositif de pulvérisation autonome selon la revendication 1 qui soit de construction relativement simple et peu coûteuse et qui convienne à une utilisation notamment dans le domaine cosmétique.The present invention relates to a new autonomous spray device according to claim 1 which is relatively simple in construction and inexpensive and suitable for use in particular in the cosmetic field.

Des modes de réalisation particuliers, voire des caractéristiques additionnelles de l'invention, sont décrits dans les revendications dépendantes.Particular embodiments, or even additional features of the invention, are described in the dependent claims.

Le dispositif de pulvérisation selon l'invention présente une structure unitaire, comporte une réserve de gaz vecteur et au moins une arrivée de produit apte à communiquer avec une réserve dudit produit, ce dernier étant aspiré dans la réserve grâce à une dépression créée dans le voisinage de l'arrivée de produit par un passage de gaz propulseur.The spraying device according to the invention has a unitary structure, comprises a reserve of carrier gas and at least one product arrival adapted to communicate with a reserve of said product, the latter being sucked into the reserve through a depression created in the vicinity the arrival of product by a passage of propellant.

La dépression peut résulter de l'émission de gaz propulseur par au moins deux orifices de sortie de gaz dont les positions respectives, c'est-à-dire les orientations et l'écartement, sont choisies de manière à ce que les jets de gaz propulseur émis par ces orifices se rencontrent.The depression may result from the emission of propellant gas by at least two gas outlet orifices whose respective positions, that is to say the orientations and the spacing, are chosen so that the gas jets thruster emitted by these orifices meet.

Grâce à la collision des jets de gaz propulseur, il est possible de mieux contrôler la forme du spray obtenu et la manière dont s'effectue la pulvérisation du produit.Thanks to the collision of the propellant jets, it is possible to better control the shape of the spray obtained and the manner in which the product is sprayed.

La demanderesse a ainsi constaté que l'on pouvait obtenir, grâce à un tel dispositif, des résultats particulièrement satisfaisants en cosmétique, notamment pour l'application d'un produit de maquillage des cheveux, de la peau ou des ongles.The applicant has thus found that it is possible to obtain, by means of such a device, particularly satisfactory results in cosmetics, especially for the application of a hair makeup product, skin or nails.

Le dispositif selon l'invention est de construction unitaire, c'est-à-dire qu'il n'a pas à être raccordé à une source d'air comprimé extérieure au dispositif et peut présenter un encombrement relativement faible, par exemple un encombrement compatible avec son transport dans un sac à main.The device according to the invention is of unitary construction, that is to say that it does not have to be connected to a source of compressed air outside the device and may have a relatively small bulk, for example a bulk compatible with carrying it in a purse.

Les orifices de sortie de gaz peuvent être disposés de manière symétrique par rapport à l'axe de pulvérisation.The gas outlet ports may be arranged symmetrically with respect to the spray axis.

Dans une réalisation particulière, l'arrivée de produit comportant au moins un orifice, les axes des orifices de sortie de gaz et d'amenée de produit peuvent être dirigés vers la surface sur laquelle est pulvérisé le produit.In a particular embodiment, the product inlet having at least one orifice, the axes of the gas outlet and product supply ports may be directed to the surface on which the product is sprayed.

Le ou les orifices d'amenée de produit peuvent se situer entre les orifices de sortie de gaz, lorsque le dispositif est observé depuis la surface sur laquelle est pulvérisé le produit.The product supply port (s) may be located between the gas outlet ports when the device is observed from the surface on which the product is sprayed.

L'organe d'amenée comportant une extrémité par laquelle sort le produit, cette extrémité est par exemple disposée sensiblement dans le même plan que les axes des orifices de sortie de gaz.The feed member having an end through which the product, this end is for example disposed substantially in the same plane as the axes of the gas outlet orifices.

L'organe d'amenée peut présenter un axe qui est coplanaire avec les axes des orifices de sortie de gaz ou en variante un axe qui est perpendiculaire à l'axe de pulvérisation.The supply member may have an axis which is coplanar with the axes of the gas outlet or alternatively an axis which is perpendicular to the spray axis.

Dans une réalisation particulière, l'organe d'amenée comporte un tube dans lequel le produit peut circuler.In a particular embodiment, the delivery member comprises a tube in which the product can circulate.

Dans une variante de réalisation, lorsque le produit est un liquide, l'organe d'amenée est réalisé dans un matériau poreux apte à permettre le transport de produit par capillarité, notamment un feutre ou un fritté.In an alternative embodiment, when the product is a liquid, the supply member is made of a porous material capable of allowing the product to be transported by capillarity, in particular a felt or sintered material.

Les orifices de sortie de gaz peuvent être agencés de telle manière que les jets de gaz émis se rencontrent directement, sans déflexion par un élément formant déflecteur.The gas outlet ports may be arranged in such a way that the emitted gas jets meet directly without deflection by a deflector member.

En variante, les orifices de sortie de gaz peuvent être agencés pour que les jets de gaz émis se rencontrent après déflexion au moins partielle par au moins un élément formant déflecteur.As a variant, the gas outlet orifices may be arranged so that the emitted gas jets meet at least partially after deflection by at least one deflector element.

Dans une réalisation particulière, les axes des orifices de sortie de gaz se rencontrent sans interception par l'élément formant déflecteur.In a particular embodiment, the axes of the gas outlet orifices meet without interception by the deflector element.

En variante, les axes des orifices de sortie de gaz sont tangents à une surface de l'élément formant déflecteur.In a variant, the axes of the gas outlet orifices are tangent to a surface the deflector member.

Les axes des orifices de sortie de gaz peuvent encore intercepter le bord d'une partie anguleuse de l'élément formant déflecteur.The axes of the gas outlet ports may further intercept the edge of an angled portion of the baffle member.

L'élément formant déflecteur peut être constitué au moins partiellement par une surface de l'organe d'amenée de produit.The baffle member may be at least partially formed by a surface of the product delivery member.

Dans une réalisation particulière, l'élément formant déflecteur comporte une partie tronconique creuse formant une buse de sortie du produit.In a particular embodiment, the baffle element comprises a hollow frustoconical portion forming an outlet nozzle of the product.

L'angle au sommet de la génératrice de cette partie tronconique, par rapport à l'axe de pulvérisation, peut être inférieur ou égal à 45°.The angle at the top of the generatrix of this frustoconical portion, with respect to the spraying axis, may be less than or equal to 45 °.

Les orifices de sortie de gaz peuvent se situer en retrait d'une extrémité libre de l'organe d'amenée, par laquelle sort le produit.The gas outlet ports may be set back from a free end of the delivery member, through which the product leaves.

Les orifices de sortie de gaz peuvent être dépourvus de canaux tourbillonnaires.The gas outlets may be devoid of vortex channels.

Dans une réalisation particulière, les axes des orifices de sortie de gaz font un angle de 45° environ avec l'axe de pulvérisation.In a particular embodiment, the axes of the gas outlet ports make an angle of approximately 45 ° with the spray axis.

Dans une réalisation particulière, le dispositif comporte deux orifices de sortie de produit, d'axes parallèles à l'axe de pulvérisation.In a particular embodiment, the device comprises two product outlet orifices, axes parallel to the spray axis.

Toujours dans une réalisation particulière, le dispositif comporte un récipient apte à contenir le gaz vecteur sous une forme liquéfiée.Still in a particular embodiment, the device comprises a container adapted to contain the carrier gas in a liquefied form.

Ce gaz vecteur est compatible avec une utilisation du dispositif de pulvérisation en cosmétique, lorsque le produit est destiné à être pulvérisé sur un support kératinique. L'utilisation d'un gaz vecteur sous forme liquidifiée permet de disposer d'une autonomie satisfaisante et de délivrer le gaz vecteur à une pression constante, ce qui rend plus facile la maîtrise de la pulvérisation du produit.This carrier gas is compatible with a use of the spraying device in cosmetics, when the product is intended to be sprayed on a keratinous support. The use of a carrier gas in liquidified form makes it possible to have a satisfactory autonomy and to deliver the carrier gas at a constant pressure, which makes it easier to control the spraying of the product.

La réserve de produit peut être contenue dans un récipient amovible, ce qui permet de changer de produit d'une utilisation à l'autre, par exemple.The stock of product can be contained in a removable container, which allows to change product from one use to another, for example.

La réserve de produit peut être contenue dans un récipient agencé pour pouvoir être supporté par le récipient contenant le gaz vecteur, ce qui facilite la manipulation de l'ensemble.The product reserve can be contained in a container arranged to be supported by the container containing the carrier gas, which facilitates the handling of the assembly.

En particulier, la réserve de produit peut être contenue dans un récipient agencé pour être vissé sur le récipient contenant le gaz vecteur.In particular, the product reserve can be contained in a container arranged to be screwed onto the container containing the carrier gas.

La réserve de produit peut encore être contenue dans un récipient rotatif par rapport au récipient contenant le gaz vecteur, ce qui permet de changer de produit pulvérisé par une simple rotation du récipient lorsque ce dernier contient deux produits différents stockés séparément.The stock of product can still be contained in a rotary container by relative to the container containing the carrier gas, which allows to change the sprayed product by a simple rotation of the container when the latter contains two different products stored separately.

Le diamètre des orifices de sortie de gaz est compris par exemple entre environ 0,2 et environ 0,5 mm et par exemple entre 0,3 et 0,4 mm.The diameter of the gas outlet orifices is for example between about 0.2 and about 0.5 mm and for example between 0.3 and 0.4 mm.

L'organe d'amenée peut comporter un orifice de sortie de produit dont le diamètre est compris par exemple entre environ 0,7 et environ 1 mm et par exemple encore entre 0,8 et 0,9 mm.The feed member may comprise a product outlet orifice whose diameter is for example between about 0.7 and about 1 mm and for example still between 0.8 and 0.9 mm.

La réserve de produit peut par exemple être contenue dans un récipient dépourvu de conduit de reprise d'air, à l'exception de l'organe d'amenée du produit, ce qui permet un auto-nettoyage de l'organe d'amenée lorsque la pulvérisation cesse, le produit contenu dans l'organe d'amenée étant aspiré dans le récipient.The product reserve may for example be contained in a container without a return air duct, with the exception of the product supply member, which allows self-cleaning of the supply member when the spraying ceases, the product contained in the feed member being sucked into the container.

En variante, le récipient peut comporter des moyens permettant une reprise d'air tels que par exemple une microfuite ou un clapet apte à s'ouvrir en cas de dépression dans le récipient contenant le produit. Si une microfuite est utilisée, elle est réalisée de manière à ne pas permettre le passage de produit lorsque le dispositif est en position couchée.Alternatively, the container may comprise means for a return of air such as for example a microfuite or a valve adapted to open in case of depression in the container containing the product. If a microleakage is used, it is performed so as not to allow the passage of product when the device is in the supine position.

Afin par exemple d'éviter un risque de fuite de produit lorsque le dispositif est transporté allongé dans un sac à main par exemple et/ou pour améliorer la conservation du produit en limitant par exemple le risque d'évaporation de constituants volatifs, le dispositif peut être agencé de manière à permettre d'interrompre la communication fluidique entre la réserve de produit et une arrivée de produit.In order for example to avoid a risk of product leakage when the device is transported elongated in a handbag for example and / or to improve the preservation of the product by limiting for example the risk of evaporation of volatile constituents, the device can be arranged to allow to interrupt the fluid communication between the product supply and a product arrival.

Ainsi, le dispositif comporte une réserve de gaz vecteur, au moins une arrivée de produit apte à être mise en communication fluidique avec une réserve dudit produit, ce dernier étant aspiré dans la réserve grâce à une dépression créée dans le voisinage de ladite au moins une arrivée de produit au moyen d'une émission de gaz vecteur.Thus, the device comprises a reserve of carrier gas, at least one product arrival adapted to be placed in fluid communication with a reserve of said product, the latter being sucked into the reserve through a depression created in the vicinity of said at least one arrival of product by means of a vector gas emission.

Selon un aspect de l'invention telle que définie dans la revendication indépendante, le dispositif se caractérise par le fait qu'il comporte au moins un obturateur apte à interrompre la communication fluidique entre ladite au moins une arrivée de produit et la réserve de produit.According to one aspect of the invention as defined in the independent claim, the device is characterized in that it comprises at least one shutter capable of interrupting the fluid communication between said at least one product inlet and the product supply.

On peut ainsi améliorer les conditions de conservation du produit dans la réserve de produit et notamment éviter l'échappement de composants volatils.It is thus possible to improve the storage conditions of the product in the product reserve and in particular to prevent the escape of volatile components.

Cela peut permettre également d'éviter les risques de fuite de produit lorsque le dispositif est transporté en étant allongé ou à l'envers, ce qui est le cas par exemple dans un sac à main.This can also avoid the risk of product leakage when the device is transported lying down or upside down, which is the case for example in a purse.

Selon un aspect de l'invention telle que définie dans la revendication indépendante, le dispositif est agencé de manière à rétablir automatiquement une communication fluidique entre ladite au moins une arrivée de produit et la réserve de produit, lors d'une émission de gaz vecteur. Le dispositif peut ainsi être agencé de manière à ce que la communication fluidique soit automatiquement interrompue lorsque cesse l'émission de gaz vecteur.According to one aspect of the invention as defined in the independent claim, the device is arranged to automatically restore fluid communication between said at least one product inlet and the product supply, during a carrier gas emission. The device can thus be arranged in such a way that the fluidic communication is automatically interrupted when the emission of vector gas ceases.

Selon une caractéristique additionnelle de l'invention, le dispositif peut comporter un bouton-poussoir apte à agir simultanément, directement ou indirectement, sur une valve de distribution de gaz vecteur et sur l'obturateur, de manière à ce qu'une communication fluidique entre l'arrivée de produit et la réserve de produit soit établie quand l'utilisateur appuie sur le bouton-poussoir pour délivrer du gaz vecteur.According to an additional characteristic of the invention, the device may comprise a pushbutton able to act simultaneously, directly or indirectly, on a vector gas distribution valve and on the shutter, so that fluid communication between the arrival of product and the supply of product is established when the user presses the push button to deliver carrier gas.

La réserve de produit peut être contenue par exemple dans un premier récipient fixé sur un deuxième récipient contenant le gaz vecteur. Les deux récipients peuvent également avoir au moins une partie commune, par exemple une cloison définissant au moins deux compartiments contenant respectivement le gaz vecteur et le produit à pulvériser.The product reserve can be contained for example in a first container fixed on a second container containing the carrier gas. The two containers may also have at least one common part, for example a partition defining at least two compartments respectively containing the carrier gas and the product to be sprayed.

Le récipient contenant le produit et le récipient contenant le gaz vecteur peuvent être liés fixement, sans déplacement de l'un par rapport à l'autre au cours de l'utilisation. On peut obtenir par exemple de cette façon un ensemble relativement compact, aisé à transporter, dans un sac à main notamment.The container containing the product and the container containing the carrier gas can be fixedly attached without moving relative to each other during use. In this way, for example, a relatively compact assembly can be obtained that is easy to transport, particularly in a handbag.

Le récipient contenant le produit peut présenter par exemple une forme annulaire, afin de ménager un passage, par exemple central, dans lequel peut s'étendre un organe de commande d'une valve équipant le récipient contenant le gaz vecteur.The container containing the product may for example have an annular shape, to provide a passage, for example central, in which may extend a control member of a valve equipping the container containing the carrier gas.

L'obturateur peut être relié opérationnellement à au moins un élément actionné par le déplacement d'un bouton-poussoir du dispositif. Un tel élément peut comporter par exemple une tige creuse, ayant au moins un canal intérieur permettant au produit contenu dans la réserve de produit de gagner l'arrivée de produit.The shutter can be operatively connected to at least one element actuated by the movement of a pushbutton of the device. Such an element may comprise for example a hollow rod, having at least one inner channel allowing the product contained in the product reserve to gain the arrival of product.

L'obturateur peut comporter par exemple au moins un joint, apte à obturer au moins un orifice par lequel le produit peut s'écouler pour gagner ladite au moins une arrivée de produit et apte à libérer cet orifice au moins partiellement lors de la distribution du produit.The shutter may comprise for example at least one seal capable of closing at least one orifice through which the product may flow to gain the at least one product inlet and able to release this orifice at least partially during dispensing. of the product.

Dans une réalisation particulière, l'obturateur est constitué par un joint monté sur une tige creuse, cette dernière étant fermée à son extrémité inférieure, le joint pouvant venir en appui par sa face supérieure contre un épaulement de la tige. Cette dernière est traversée par exemple par au moins un orifice d'admission de produit, dont le diamètre est inférieur ou égal à l'épaisseur du joint. Celui-ci est apte à venir en butée par sa face inférieure contre une paroi d'appui, fixe, quand la tige creuse est enfoncée, de sorte que le joint est alors comprimé et dégage au moins partiellement l'orifice d'admission, afin de permettre un écoulement de produit en direction de ladite au moins une arrivée de produit. Le joint peut en outre, par exemple, s'appliquer à sa périphérie contre la surface intérieure d'un conduit dans lequel la tige creuse peut se déplacer axialement, ce conduit pouvant communiquer librement avec l'extérieur, auquel cas le joint permet d'obtenir une fermeture étanche de l'intervalle situé entre la tige creuse et la surface intérieure du conduit. Ce conduit peut se raccorder à son extrémité supérieure à un couvercle fermant supérieurement le récipient contenant le produit, par exemple. La tige creuse peut être actionnée par exemple par le déplacement d'un bouton-poussoir commandant l'émission de gaz vecteur. L'espace intérieur à la paroi d'appui contre laquelle le joint peut venir en butée par sa face inférieure peut communiquer avec le récipient contenant le produit, par exemple par l'intermédiaire d'une gorge annulaire réalisée dans une paroi de fond du récipient. Le conduit précité peut se raccorder de manière étanche à la paroi d'appui tubulaire précitée.In a particular embodiment, the shutter is constituted by a seal mounted on a hollow rod, the latter being closed at its lower end, the seal being supported by its upper face against a shoulder of the rod. The latter is traversed for example by at least one product inlet, whose diameter is less than or equal to the thickness of the seal. It is adapted to abut by its lower face against a fixed support wall, when the hollow rod is depressed, so that the seal is then compressed and at least partially releases the intake orifice, so to allow a flow of product towards said at least one product inlet. The seal may also, for example, be applied at its periphery against the inner surface of a duct in which the hollow rod can move axially, this duct can communicate freely with the outside, in which case the seal allows obtain a tight closure of the gap between the hollow rod and the inner surface of the conduit. This duct may be connected at its upper end to a lid closing the container containing the product, for example. The hollow rod can be actuated for example by the movement of a push button controlling the emission of carrier gas. The space inside the bearing wall against which the seal can abut by its lower face can communicate with the container containing the product, for example by means of an annular groove formed in a bottom wall of the container . The aforesaid conduit can be connected sealingly to the above-mentioned tubular support wall.

Selon une caractéristique additionnelle de l'invention, le dispositif peut comporter un bouton-poussoir réalisé par assemblage d'une partie inférieure et d'une partie supérieure. La partie inférieure peut être réalisée par exemple d'un seul tenant avec une tige d'actionnement, et s'étendre dans un passage, par exemple central, du récipient contenant le produit. La tige de commande de la valve contenant le gaz vecteur peut être engagée dans la tige d'actionnement du bouton-poussoir.According to an additional feature of the invention, the device may comprise a push-button made by assembling a lower part and an upper part. The lower part can be made for example in one piece with an actuating rod, and extend in a passage, for example central, of the container containing the product. The control rod of the valve containing the carrier gas can be engaged in the operating rod of the push button.

Le produit qui est pulvérisé peut être un liquide, un liquide contenant des particules solides en suspension ou une poudre suffisamment fine.The product which is sprayed may be a liquid, a liquid containing suspended solid particles or a sufficiently fine powder.

On a représenté sur la figure 1 un dispositif de pulvérisation 1 conforme à un premier exemple de mise en oeuvre de l'invention, comportant un premier récipient 2 contenant une réserve de gaz vecteur et un deuxième récipient 3 contenant un liquide à pulvériser.We have shown on the figure 1 a spraying device 1 according to a first example of implementation of the invention, comprising a first container 2 containing a reservoir of carrier gas and a second container 3 containing a liquid to be sprayed.

Dans l'exemple décrit, le gaz vecteur est présent à l'état liquéfié dans le récipient 2 et sa nature est choisie de manière à être compatible avec une pulvérisation sur un support kératinique tel que la peau, les ongles ou les cheveux.In the example described, the carrier gas is present in the liquefied state in the container 2 and its nature is chosen so as to be compatible with a spray on a keratinous support such as skin, nails or hair.

Bien entendu, on ne sort pas du cadre de la présente invention lorsque d'autres gaz vecteurs sont utilisés, par exemple de l'air ou de l'azote comprimé, et que le support sur lequel le liquide contenu dans le récipient 3 est pulvérisé est non kératinique.Of course, it is not beyond the scope of the present invention when other carrier gases are used, for example compressed air or nitrogen, and the support on which the liquid contained in the container 3 is sprayed. is non-keratinous.

Le dispositif de pulvérisation 1 comporte outre les récipients 2 et 3 un ensemble de distribution 4 comportant une tête de pulvérisation 5 et un organe d'actionnement 56 tel qu'un bouton-poussoir.The spraying device 1 comprises, in addition to the containers 2 and 3, a dispensing assembly 4 comprising a spray head 5 and an actuating member 56 such as a push-button.

La tête de pulvérisation 5 comporte une buse centrale 6 pour la distribution du liquide contenu dans le récipient 3 et deux buses latérales 7 pour l'émission du gaz vecteur.The spray head 5 comprises a central nozzle 6 for dispensing the liquid contained in the container 3 and two lateral nozzles 7 for the emission of the carrier gas.

On a représenté plus en détail sur la figure 2 les buses 6 et 7.We have shown in more detail on the figure 2 the nozzles 6 and 7.

La buse 6 présente un canal intérieur 8, d'axe X, ce dernier coïncidant avec l'axe de pulvérisation.The nozzle 6 has an inner channel 8, X axis, the latter coinciding with the spray axis.

Les buses 7 comportent chacune un canal intérieur 9 d'axe Y, les axes Y faisant chacun un angle de 45° avec l'axe X et étant contenus dans le même plan que l'axe X.The nozzles 7 each comprise an inner channel 9 of Y axis, the Y axes each being at an angle of 45 ° with the X axis and being contained in the same plane as the X axis.

Le canal 8 communique en permanence avec le produit contenu dans le récipient 3 et les canaux 9 communiquent avec le gaz propulseur contenu dans le récipient 2 par l'intermédiaire d'une valve actionnée par le bouton-poussoir 56.The channel 8 communicates continuously with the product contained in the container 3 and the channels 9 communicate with the propellant gas contained in the container 2 via a valve actuated by the push-button 56.

Le diamètre des orifices 14 de sortie du gaz propulseur est de 0,4 mm par exemple et celui de l'orifice 15 de sortie du liquide de 0,9 mm par exemple.The diameter of the orifices 14 for the output of the propellant gas is 0.4 mm for example and that of the liquid outlet orifice 15 of 0.9 mm for example.

Lorsque l'utilisateur appuie sur le bouton-poussoir 56, du gaz propulseur circule dans les canaux 9 et se détend à la sortie des buses 7, provoquant par effet Venturi une dépression en avant de la buse 6 et l'aspiration de produit dans le canal 8.When the user presses the push-button 56, propellant gas flows in the channels 9 and expands at the outlet of the nozzles 7, causing by the Venturi effect a depression in front of the nozzle 6 and the suction of product into the channel 8.

Du fait de l'orientation des axes Y, les jets de gaz propulseur émis par les buses 7 se rencontrent, ce qui permet d'obtenir une pulvérisation ayant des caractéristiques de granulométrie et de géométrie du spray compatibles avec l'obtention de résultats satisfaisants en cas d'application sur un support kératinique.Due to the orientation of the Y axes, the jet of propellant gas emitted by the nozzles 7 meet, which makes it possible to obtain a spray having characteristics of particle size and of spray geometry compatible with the obtaining of satisfactory results. case of application on a keratin support.

Dans la configuration particulière illustrée sur la figure 2, la buse 6 agit en outre comme un élément formant déflecteur et dévie vers l'avant une partie des jets de gaz propulseur émis par les buses 7.In the particular configuration illustrated on the figure 2 , the nozzle 6 also acts as a deflector element and deflects forward a portion of the propellant gas jets emitted by the nozzles 7.

En d'autres termes, les jets de gaz propulseur heurtent au moins partiellement la buse 6 et prennent alors une orientation plus proche de celle de l'axe de pulvérisation.In other words, the jet of propellant gas at least partially collide the nozzle 6 and then take an orientation closer to that of the spray axis.

On remarquera que la buse 6 présente une partie tronconique creuse 11 dont la génératrice fait un angle avec l'axe de pulvérisation X qui est inférieur à l'angle que fait chaque axe Y avec l'axe X.It will be noted that the nozzle 6 has a hollow frustoconical portion 11 whose generator is at an angle to the spray axis X which is smaller than the angle that each Y axis makes with the X axis.

Dans l'exemple représenté sur la figure 2, la buse 6 présente une face d'extrémité 12 plane et perpendiculaire à l'axe X et l'axe Y de chaque buse 7 intercepte le bord 13 circulaire de la face d'extrémité 12.In the example shown on the figure 2 , the nozzle 6 has a flat end face 12 perpendicular to the X axis and the Y axis of each nozzle 7 intercepts the circular edge 13 of the end face 12.

La distance H entre la face d'extrémité 12 de la buse 6 et le bord 16 de la face avant de chaque buse 7 est de 1,7 mm environ, par exemple.The distance H between the end face 12 of the nozzle 6 and the edge 16 of the front face of each nozzle 7 is about 1.7 mm, for example.

Dans l'exemple de réalisation des figures 1 et 2, les buses 6 et 7 sont constituées par des pièces rapportées.In the exemplary embodiment of Figures 1 and 2 the nozzles 6 and 7 are constituted by inserts.

Bien entendu, on ne sort pas du cadre de la présente invention lorsque les orifices de sortie du liquide et du gaz propulseur sont constitués par les extrémités de canaux intérieurs réalisés dans une pièce monobloc, comme illustré sur la figure 3.Of course, it is not beyond the scope of the present invention when the liquid and propellant outlet orifices are constituted by the ends of inner channels made in a single piece, as shown in FIG. figure 3 .

Sur cette figure, on a représenté une tête de pulvérisation 20 traversée par des canaux latéraux 21 communiquant avec la réserve de gaz propulseur et un canal central 22 communiquant avec la réserve de liquide et débouchant à l'extérieur par un orifice 24 d'axe X.In this figure, there is shown a spray head 20 traversed by side channels 21 communicating with the propellant reserve and a central channel 22 communicating with the liquid reserve and opening out through an orifice X axis X .

Les canaux 21 débouchent à l'extérieur par des orifices distincts 23 d'axes Y sécants avec l'axe X.The channels 21 open to the outside through separate orifices 23 intersecting Y axes with the X axis.

Dans le mode de réalisation de la figure 3, les jets de gaz propulseur émis par les canaux 21 se percutent directement, sans déflexion préalable par un élément formant déflecteur tel que la buse 6 précédemment décrite.In the embodiment of the figure 3 the jets of propellant gas emitted by the channels 21 strike directly, without prior deflection by a deflector element such as the nozzle 6 described above.

L'invention n'est pas limitée à la distribution d'un liquide unique et l'on peut, sans sortir du cadre de la présente invention, distribuer un mélange d'au moins deux produits, l'un des produits pouvant être contenu dans le récipient contenant le gaz propulseur et entraîné avec ce dernier.The invention is not limited to the distribution of a single liquid and it is possible, without departing from the scope of the present invention, to dispense a mixture of at least two products, one of the products being able to be contained in the container containing the propellant and driven with the latter.

Les deux produits peuvent également être contenus dans deux récipients distincts, différents de celui contenant le gaz propulseur.The two products can also be contained in two separate containers, different from that containing the propellant.

Dans ce cas, l'amenée des liquides peut se faire par deux voies séparées, comme illustré sur la figure 4.In this case, the supply of the liquids can be done by two separate ways, as illustrated on the figure 4 .

Sur cette figure, le canal 22 a été remplacé par deux canaux 30 et 31 communiquant respectivement avec deux réserves de produits différents, par exemple deux produits devant être conditionnés séparément et mélangés extemporanément.In this figure, the channel 22 has been replaced by two channels 30 and 31 communicating respectively with two different product reserves, for example two products to be packaged separately and mixed extemporaneously.

Les axes Z des orifices 32 et 33 des canaux 30 et 31 sont parallèles à l'axe X de pulvérisation.The Z axes of the orifices 32 and 33 of the channels 30 and 31 are parallel to the X axis of spraying.

L'axe de pulvérisation X peut être horizontal ou avoir une orientation autre, en fonction de l'ergonomie du dispositif de pulvérisation et de l'emplacement de la zone à traiter.The spray axis X may be horizontal or have a different orientation, depending on the ergonomics of the spray device and the location of the area to be treated.

Le dispositif de pulvérisation peut être prévu pour pouvoir fonctionner tête en haut ou tête en bas.The spraying device can be provided to operate upside down or upside down.

Le produit peut être contenu dans un récipient amovible, comme cela va maintenant être décrit en référence à la figure 5.The product can be contained in a removable container, as will now be described with reference to the figure 5 .

Les figures 5 et 6, bien que non comprises dans l'objet des revendications, sont utiles à la compréhension de l'invention.The Figures 5 and 6 although not included in the subject matter of the claims, are useful for understanding the invention.

Sur cette figure, on a représenté un dispositif 40 comportant un récipient 41 contenant du gaz propulseur et un récipient 42 contenant une réserve de produit P.In this figure, there is shown a device 40 comprising a container 41 containing propellant and a container 42 containing a reserve of product P.

Le récipient 41 est pourvu d'un col fileté 43.The container 41 is provided with a threaded neck 43.

Une tête de pulvérisation 45 est fixée sur la tige creuse de commande 46 de la valve du récipient 41.A spray head 45 is fixed on the hollow control rod 46 of the valve of the container 41.

Le récipient 42 comporte une jupe de montage annulaire 47, agencée pour se visser sur le col fileté 43.The container 42 has an annular mounting skirt 47, arranged to screw onto the threaded neck 43.

Le récipient 42 est fermé de manière étanche en partie supérieure par un couvercle 48.The container 42 is sealed at the top by a lid 48.

Le bouton-poussoir 45 présente deux orifices 48 de distribution de gaz propulseur formant un angle entre eux et dont les axes Y sont sécants et se coupent sensiblement à l'aplomb d'un organe d'amenée de liquide 50, constitué dans l'exemple de la figure 5 par un tube plongeant jusque dans le fond du récipient 42.The pushbutton 45 has two orifices 48 for distributing propellant gas forming an angle between them and whose Y axes are intersecting and intersect substantially vertically above a liquid supply member 50, constituted in the example of the figure 5 by a dip tube into the bottom of the container 42.

Le tube 50 traverse de manière étanche le couvercle 48.The tube 50 passes through the cover 48 in a sealed manner.

L'extrémité supérieure du tube 50 est pourvue d'un orifice 51 permettant la sortie du liquide sous l'effet de la dépression créée par l'éjection de gaz propulseur par les orifices 48, lorsque l'utilisateur appuie sur le bouton-poussoir 45.The upper end of the tube 50 is provided with an orifice 51 allowing the exit of the liquid under the effect of the depression created by the ejection of propellant gas through the orifices 48, when the user presses the push button 45 .

La fixation amovible du récipient 42 sur le récipient 41 permet à l'utilisateur de reconstituer la réserve de liquide lorsque celle-ci est épuisée en remplaçant le récipient 42 par un nouveau récipient rempli de produit.The removable attachment of the container 42 to the container 41 allows the user to reconstitute the liquid reserve when it is exhausted by replacing the container 42 with a new container filled with product.

L'utilisateur peut également, grâce au montage amovible du récipient 42 sur le récipient 41, sélectionner le récipient 42 parmi plusieurs récipients contenant des produits différents, par exemple des produits de couleurs différentes.The user can also, thanks to the removable mounting of the container 42 on the container 41, select the container 42 from several containers containing different products, for example products of different colors.

Ainsi, l'utilisateur n'utilise qu'un seul récipient 41 contenant le gaz propulseur en liaison avec un récipient choisi parmi plusieurs récipients contenant des produits différents.Thus, the user uses only one container 41 containing the propellant gas in connection with a container chosen from several containers containing different products.

Il convient de remarquer que le récipient 42 ne comporte pas d'orifice de reprise d'air autre que le canal intérieur du tube 50.It should be noted that the container 42 has no air intake port other than the inner channel of the tube 50.

Lorsque du produit est distribué lors de l'actionnement du bouton-poussoir 45, une dépression se créée dans le récipient 42 et lors de l'arrêt de la distribution, le retour à la pression d'équilibre dans le récipient 42 s'accompagne d'une descente du produit dans le tube 50, ce qui permet de réaliser en quelque sorte un auto-nettoyage du tube 50 et limite le risque de bouchage de celui-ci.When the product is dispensed during the actuation of the push button 45, a depression is created in the container 42 and when stopping the distribution, the return to the equilibrium pressure in the container 42 is accompanied by a descent of the product in the tube 50, which allows a kind of self-cleaning of the tube 50 and limits the risk of clogging thereof.

Bien entendu, l'organe d'amenée n'est pas limité à un tube dans lequel le produit est aspiré et le tube 50 peut être remplacé par exemple par un matériau capable d'absorber par capillarité le produit P, par exemple une mèche, un feutre ou un fritté.Of course, the supply member is not limited to a tube in which the product is sucked and the tube 50 may be replaced for example by a material capable of absorbing the product P by capillarity, for example a wick, felt or sintered.

Sur la figure 6, on a représenté une pointe-feutre 60 remplaçant le tube 50 de la figure 5, le couvercle 48 étant alors pourvu d'une jupe 61 permettant la fixation d'un capuchon de fermeture amovible 62 qui isole la pointe-feutre 60 de l'air ambiant en l'absence d'utilisation et évite que celle-ci ne sèche.On the figure 6 , there is shown a felt tip 60 replacing the tube 50 of the figure 5 , the cover 48 then being provided with a skirt 61 allowing the attachment of a removable closure cap 62 which isolates the felt tip 60 from the ambient air in the absence of use and prevents it from drying out .

L'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.The invention is not limited to the embodiments which have just been described.

On peut notamment monter une pluralité de réserves contenant différents liquides sur un barillet, de manière similaire à ce qui a été décrit dans la demande de brevet français FR-A-2 781 208 précitée.In particular, a plurality of reservoirs containing different liquids can be mounted on a cylinder, in a manner similar to that described in the application for French patent FR-A-2 781 208 supra.

Le dispositif de pulvérisation 100 représenté à la figure 7 comporte un récipient pressurisé 101 contenant par exemple un gaz vecteur sous forme liquéfiée, par exemple du butane, de l'isopropane, de l'isobutane ou un composé fluoré, et un ensemble de distribution 102 comportant un bouton-poussoir 103 et un récipient 104 contenant un produit P, par exemple un fond de teint liquide. Le produit P peut par exemple être un liquide comportant une suspension de particules solides.The spraying device 100 shown in FIG. figure 7 comprises a pressurized container 101 containing for example a carrier gas in liquefied form, for example butane, isopropane, isobutane or a fluorinated compound, and a dispensing assembly 102 comprising a push-button 103 and a container 104 containing a product P, for example a liquid foundation. The product P may for example be a liquid comprising a suspension of solid particles.

Le récipient 104 comporte, dans l'exemple décrit, une cavité 105 de forme générale annulaire autour d'un axe W, cette cavité 105 contenant le produit P étant délimitée radialement à l'extérieur par une première paroi tubulaire 105a et radialement à l'intérieur par une deuxième paroi tubulaire 105b. Les parois 105a et 105b sont réunies à leur partie inférieure par une paroi de fond 105c, qui comporte une gorge annulaire 107, d'axe W, dont le rôle sera précisé plus loin.The container 104 comprises, in the example described, a cavity 105 of generally annular shape about an axis W, this cavity 105 containing the product P being delimited radially outwardly by a first tubular wall 105a and radially inwardly by a second tubular wall 105b. The walls 105a and 105b are joined at their lower part by a bottom wall 105c, which has an annular groove 107, W axis, whose role will be specified later.

La cavité 105 est fermée supérieurement par un couvercle 110, sur la face inférieure duquel se raccorde un conduit 111 d'axe parallèle à l'axe W. Le couvercle 110 vient prendre appui contre un épaulement 112 réalisé à l'extrémité supérieure de la paroi 105a.The cavity 105 is closed topally by a cover 110, on the lower face of which is connected a conduit 111 of axis parallel to the axis W. The cover 110 bears against a shoulder 112 formed at the upper end of the wall 105a.

Le conduit 111 s'étend sur sensiblement toute la hauteur de la cavité 105 et vient s'assembler à son extrémité inférieure avec une paroi 114, formant saillie vers le haut sur la paroi de fond 105c, à l'aplomb de la gorge 107. L'assemblage du conduit 111 et de la paroi 114 est réalisé par exemple par emmanchement. La paroi 114 précitée peut être continue ou discontinue et peut par exemple former des plots.The conduit 111 extends over substantially the entire height of the cavity 105 and is assembled at its lower end with a wall 114, projecting upwards on the bottom wall 105c, directly above the groove 107. The assembly of the conduit 111 and the wall 114 is made for example by fitting. The aforementioned wall 114 may be continuous or discontinuous and may for example form pads.

Le conduit 111 et le couvercle 110 peuvent être réalisés d'un seul tenant, par exemple.The conduit 111 and the cover 110 may be made in one piece, for example.

Le bouton-poussoir 103 est formé par exemple par l'assemblage d'une partie supérieure 103a et d'une partie inférieure 103b. Dans l'exemple illustré, cette dernière est réalisée d'un seul tenant avec une tige creuse 120 d'actionnement d'une valve du récipient pressurisé 101, pouvant coulisser à l'intérieur de la paroi 105b.The push button 103 is formed for example by the assembly of an upper portion 103a and a lower portion 103b. In the illustrated example, the latter is made in one piece with a hollow rod 120 for actuating a valve of the pressurized container 101, slidable inside the wall 105b.

Cette valve peut comporter une tige creuse 121, engagée de manière étanche dans l'extrémité inférieure de la tige 120, et venant en appui par un épaulement contre la face d'extrémité inférieure de la tige 120.This valve may comprise a hollow rod 121, sealingly engaged in the lower end of the rod 120, and bearing by a shoulder against the lower end face of the rod 120.

Le bouton-poussoir 103 peut être déplacé selon l'axe W pour agir sur la tige de commande 121, auquel cas du gaz vecteur circule dans le conduit intérieur de la tige 120 et gagne une cavité 125, avec laquelle communiquent, comme on peut le voir sur la figure 2, deux conduits intérieurs 126a et 126b débouchant à l'extérieur du bouton-poussoir par des orifices de sortie de gaz vecteur 127a et 127b. Les orifices 127a et 127b ont par exemple des axes Za et Zb sensiblement perpendiculaires et font chacun par exemple un angle de 45° environ avec la direction de pulvérisation.The push-button 103 can be moved along the axis W to act on the control rod 121, in which case the carrier gas circulates in the inner conduit of the rod 120 and gains a cavity 125, with which communicate, as can be see on the figure 2 , two inner conduits 126a and 126b opening out of the pushbutton through vector gas outlet ports 127a and 127b. The orifices 127a and 127b have, for example, substantially perpendicular axes Za and Zb and are, for example, at an angle of approximately 45.degree. With the direction of spraying.

Le bouton-poussoir 103 comporte également un orifice 130 d'arrivée du produit, d'axe Zc, par exemple confondu avec la direction de pulvérisation. L'orifice 130 communique par exemple avec l'intérieur d'une tige creuse 140 fermée à son extrémité inférieure par une paroi 141, comme on peut le voir sur la figure 11, et sur laquelle est engagé un joint annulaire 150 servant d'obturateur, ce joint 150 étant par exemple réalisé en élastomère.The push-button 103 also comprises an orifice 130 for the arrival of the product, of axis Zc, for example, coinciding with the direction of spraying. The orifice 130 communicates for example with the interior of a hollow rod 140 closed at its end lower by a wall 141, as can be seen on the figure 11 and on which is engaged an annular seal 150 serving as a shutter, this seal 150 being for example made of elastomer.

Dans l'exemple illustré, le joint 150 vient en appui par sa face supérieure plane 151 contre une nervure annulaire 142 de la tige 140. Cette dernière présente au moins un orifice 145 d'admission de produit, dont le diamètre est inférieur ou égal à l'épaisseur nominale du joint 150, mesurée le long de l'axe de la tige 140. L'orifice 145 est positionné de telle sorte que le joint 150, lorsqu'il est en appui au repos contre la nervure 142, recouvre complètement l'orifice 145 et empêche le produit P contenu dans la cavité 105 de pénétrer par l'orifice 145 dans la tige 140.In the example illustrated, the seal 150 bears on its flat upper face 151 against an annular rib 142 of the rod 140. The latter has at least one product inlet orifice 145, the diameter of which is less than or equal to the nominal thickness of the seal 150, measured along the axis of the rod 140. The orifice 145 is positioned so that the seal 150, when resting against the rib 142, completely covers the orifice 145 and prevents the product P contained in the cavity 105 from penetrating through the orifice 145 in the rod 140.

La tige 140 est par exemple fixée à son extrémité supérieure dans un logement 160 du bouton-poussoir 103 et peut se déplacer conjointement avec la tige 120 lorsque l'utilisateur appuie sur le bouton-poussoir 103. Lors de l'enfoncement de la tige 140, le joint 150 est comprimé entre la paroi 114 et la nervure 142, une telle compression ayant pour effet de réduire son épaisseur et de libérer au moins partiellement l'orifice 145, de telle sorte que du produit contenu dans la cavité 105 peut circuler à travers l'orifice 145, remonter dans la tige 140 et gagner l'orifice d'arrivée de produit 130.The rod 140 is for example fixed at its upper end in a housing 160 of the push-button 103 and can move together with the rod 120 when the user presses the push-button 103. During the depression of the rod 140 , the seal 150 is compressed between the wall 114 and the rib 142, such compression having the effect of reducing its thickness and at least partially releasing the orifice 145, so that the product contained in the cavity 105 can flow to through the orifice 145, go up the rod 140 and reach the product inlet port 130.

Lorsque le bouton-poussoir 103 est relâché, la tige 140 remonte avec ce dernier et le joint 150 peut reprendre grâce à une mémoire de forme une épaisseur suffisante pour obturer l'orifice 145.When the push button 103 is released, the rod 140 rises with the latter and the seal 150 can resume through a shape memory of sufficient thickness to close the orifice 145.

Le fonctionnement du dispositif 100 est le suivant. Pour pulvériser du produit P, l'utilisateur appuie sur le bouton-poussoir 103, ce qui provoque l'enfoncement de la tige 121 de la valve du récipient et l'émission de gaz vecteur dans le canal intérieur de la tige 120. Le gaz vecteur peut circuler par les conduits 126a et 126b et sortir par les orifices 127a et 127b, ce qui crée par effet Venturi en avant de l'orifice d'arrivée de produit 130 une dépression. L'enfoncement du bouton-poussoir 103 a également pour conséquence de déplacer la tige 140 et de comprimer le joint 150, comme expliqué plus haut. L'orifice 145 est alors au moins partiellement libéré et du produit P contenu dans la cavité 105 peut, sous l'effet de la dépression précitée, remonter dans le canal intérieur de la tige 140 et gagner l'orifice 130. Le produit est alors pulvérisé dans la direction de l'axe Zc, tant que l'utilisateur appuie sur le bouton-poussoir 103. Lorsque ce dernier est relâché, il peut remonter dans sa position de repos du fait que la tige de commande 121 est rappelée par des moyens élastiques propres au récipient 101 dans sa position initiale et sous l'effet de l'élasticité propre du joint 150. Ce dernier, en reprenant sa forme initiale, obture l'orifice 145, de sorte qu'en cas de transport du dispositif 100 en position allongée ou à l'envers, le produit P reste contenu dans la cavité 105 et ne risque pas de fuir par l'orifice d'arrivée de produit 130.The operation of the device 100 is as follows. To spray product P, the user presses the push button 103, which causes the depression of the stem 121 of the valve of the container and the emission of carrier gas in the inner channel of the rod 120. The gas vector can flow through the conduits 126a and 126b and out through the orifices 127a and 127b, which creates by Venturi effect in front of the product inlet port 130 a depression. The depression of the push-button 103 also results in moving the rod 140 and compressing the gasket 150, as explained above. The orifice 145 is then at least partially released and the product P contained in the cavity 105 can, under the effect of the aforesaid depression, go up in the inner channel of the rod 140 and reach the orifice 130. The product is then sprayed in the direction of the Zc axis, as the user presses the push button 103. When the latter is released, it can go back to its rest position because the control rod 121 is recalled by elastic means proper to the container 101 in its initial position and under the effect of the own elasticity of the seal 150. The latter, by resuming its initial shape, closes the orifice 145, so that in case of transporting the device 100 in the extended position or upside down, the product P remains contained in the cavity 105 and is not likely to leak through the product inlet port 130.

Le récipient 104 peut être par exemple fixé de manière amovible sur le récipient contenant le gaz vecteur, de manière à permettre, le cas échéant, de changer de récipient 104 parce que la réserve de produit est épuisée. Cela peut permettre aussi de remplacer le récipient 101 ou de pulvériser différents produits successivement au moyen d'un unique récipient 101.The container 104 may for example be removably attached to the container containing the carrier gas, so as to allow, if necessary, to change the container 104 because the supply of product is exhausted. This can also make it possible to replace the container 101 or to spray different products successively by means of a single container 101.

Dans l'exemple correspondant aux figures 7 à 11, l'arrivée de produit est constituée par l'extrémité d'un conduit formé dans le bouton-poussoir mais on ne sort pas du cadre de la présente invention lorsque l'arrivée de produit comporte un matériau capable d'absorber par capillarité du produit, par exemple une mèche, un feutre ou un fritté.In the example corresponding to Figures 7 to 11 , the arrival of product is constituted by the end of a conduit formed in the pushbutton but it is not beyond the scope of the present invention when the arrival of product comprises a material capable of absorbing by capillarity of the product for example a wick, a felt or a sinter.

Bien entendu, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et, d'une manière générale, on peut remplacer l'obturateur qui a été décrit par tous moyens d'obturation appropriés, par exemple des moyens d'obturation comportant, comme illustré à la figure 12, deux parois coaxiales 201, 202 mobiles l'une par rapport à l'autre, constituant un obturateur.Of course, the invention is not limited to the examples which have just been described and, in general, it is possible to replace the shutter which has been described by any appropriate sealing means, for example means of sealing. shutter comprising, as illustrated in figure 12 , two coaxial walls 201, 202 movable relative to each other, constituting a shutter.

La paroi 202, la plus intérieure, peut être formée par exemple par une tige creuse solidaire du bouton-poussoir, étant fermée à son extrémité inférieure. Le produit peut remonter à l'intérieur de cette tige lorsqu'une dépression est créée par une émission de gaz vecteur.The wall 202, the innermost, may be formed for example by a hollow rod integral with the pushbutton, being closed at its lower end. The product can go up inside this rod when a depression is created by a vector gas emission.

La paroi 201, la plus extérieure, est fixe et elle est apte à obturer un orifice 203 de la paroi 202 lorsque le bouton-poussoir est au repos. La paroi 202 comporte un orifice 204 en regard duquel l'orifice 203 peut venir, lorsque le bouton-poussoir est enfoncé, ce qui libère au moins partiellement l'orifice 203, pour permettre au produit de gagner l'arrivée de produit.The wall 201, the outermost, is fixed and is able to close an orifice 203 of the wall 202 when the pushbutton is at rest. The wall 202 has an orifice 204 opposite which the orifice 203 can come when the push button is depressed, which at least partially releases the orifice 203, to allow the product to gain the arrival of product.

Un clapet, par exemple à bille, commandé en ouverture par le déplacement du bouton-poussoir pourrait également être utilisé, comme illustré à la figure 13. Un tel clapet peut prendre une position fermée lorsque le bouton-poussoir est relâché par l'utilisateur. Dans l'exemple illustré, le clapet comporte une bille 210 formant obturateur, rappelée dans une position d'obturation par un ressort 211. Une tige d'actionnement 212 est agencée pour être déplacée vers le bas lorsque le bouton-poussoir est enfoncé. Le produit peut alors s'écouler par un conduit 213 pour gagner la zone où la dépression est créée, afin d'être pulvérisé.A valve, for example a ball valve, controlled in opening by the displacement of the push-button could also be used, as illustrated in FIG. figure 13 . Such a valve can take a closed position when the pushbutton is released by the user. In the illustrated example, the valve comprises a ball 210 forming a shutter, returned to a closed position by a spring 211. An actuating rod 212 is arranged to be moved downwardly when the pushbutton is depressed. The product can then flow through a conduit 213 to reach the area where the depression is created, to be sprayed.

La gorge annulaire 107 pourrait, dans des variantes de réalisation, être supprimée, par exemple si l'on permet au produit de gagner l'espace intérieur à la paroi 114, par exemple grâce à des ouvertures réalisées dans cette paroi et dans l'extrémité inférieure du conduit 111.The annular groove 107 could, in alternative embodiments, be eliminated, for example if the product is allowed to gain the interior space to the wall 114, for example by means of openings made in this wall and in the end. lower duct 111.

On ne sort pas du cadre de l'invention lorsque l'arrivée de produit comporte un organe d'amenée de produit tel qu'un feutre, une mousse, un fritté, comme illustré sur la figure 14. Sur cette figure, on a représenté une pointe feutre 220 servant à amener le produit par capillarité dans la zone où la dépression est créée, cette pointe feutre étant par exemple fixée dans l'orifice 130 précité.It is not beyond the scope of the invention when the product inlet comprises a product supply member such as a felt, a foam, a sinter, as illustrated in FIG. figure 14 . In this figure, there is shown a felt tip 220 used to bring the product by capillarity in the area where the vacuum is created, this felt tip being for example fixed in the hole 130 above.

La tige de commande 121 du récipient contenant le gaz vecteur pourrait encore commander la distribution de gaz vecteur en étant inclinée par rapport à l'axe W, à condition de réaliser le bouton-poussoir en conséquence.The control rod 121 of the container containing the carrier gas could still control the carrier gas distribution by being inclined with respect to the axis W, provided to realize the push button accordingly.

Le récipient 104 peut être réalisé sans reprise d'air ou avec reprise d'air, notamment si une utilisation prolongée est envisagée.The container 104 can be made without air intake or with air intake, especially if prolonged use is envisaged.

Pour permettre une reprise d'air, on peut par exemple réaliser une microfuite 230, comme illustré sur la figure 9, à travers le couvercle 110 ou entre le couvercle et la paroi 105a du récipient 104, ce qui correspond à l'exemple représenté sur la figure 9. Une telle microfuite est réalisée de manière à empêcher le passage du produit notamment lorsque le dispositif est en position couchée, mais à permettre le passage de l'air.To allow a return of air, one can for example make a microfuite 230, as illustrated on the figure 9 , through the cover 110 or between the cover and the wall 105a of the container 104, which corresponds to the example shown in FIG. figure 9 . Such a microleak is made to prevent the passage of the product especially when the device is in a supine position, but to allow the passage of air.

On peut encore prévoir, par exemple, un clapet 240 apte à obturer un orifice de reprise d'air 241, comme illustré à la figure 10. Le clapet 240 s'ouvre en cas de dépression à l'intérieur du récipient contenant le produit et obture l'orifice 241 dans le cas contraire.It is also possible to provide, for example, a valve 240 capable of closing off an air intake orifice 241, as illustrated in FIG. figure 10 . The valve 240 opens in case of depression inside the container containing the product and closes the orifice 241 in the opposite case.

Le clapet 240 peut être par exemple surmoulé sur le couvercle 110, mais pourrait encore être réalisé autrement sans que l'on sorte du cadre de la présente invention.The valve 240 may for example be overmolded on the cover 110, but could still be made otherwise without departing from the scope of the present invention.
