Abstract

The aerosol distribution head comprises a push button (8) containing two ducts and two nozzles (30a,30b). One part (36a,36b) of each duct is radial and the other axial part, in communication with the nozzle, is parallel to the nozzle axis. This results in the sprays (sa,sb) leaving each nozzle forming a single homogeneous spray (S). The axes of each nozzle are in the same plane and are oriented transverse to the push button longitudinal axis. The nozzle axes form an angle of 20 degrees to 120 degrees . The axis of each nozzle is separated from the axis of the duct axial part by a distance (d) which is equal to the length (L) of the nozzle pillar plus the width (l) of the duct radial part.

Description

L'invention est relative à une tête de distribution d'un produit liquide sous forme d'aérosol et à un distributeur comprenant un réservoir pour le produit, muni de cette tête de distribution. Le distributeur peut notamment être utilisé dans les domaines cosmétique pour la distribution d'une laque capillaire, d'un déodorant, d'une lotion anti-poux, pharmaceutique pour la distribution de répulsifs pour insectes et agricole pour la distribution d'insecticides.The invention relates to a dispensing head for a liquid product in the form of an aerosol and to a dispenser comprising a reservoir for the product, provided with this dispensing head. The dispenser can in particular be used in the cosmetic fields for the distribution of a hair spray, a deodorant, an anti-lice lotion, pharmaceutical for the distribution of insect repellents and agricultural for the distribution of insecticides.

Le distributeur de l'invention comprend, de façon connue, une tête de distribution de produit, un réservoir muni d'une valve de distribution équipée d'une tige creuse de commande comportant une entrée de produit et une sortie de produit; la tête de distribution comporte un bouton poussoir pour actionner la valve via la tige, au moins deux buses logées dans le bouton-poussoir et au moins deux conduits raccordant respectivement chaque buse à la sortie de la tige.The dispenser of the invention comprises, in known manner, a product dispensing head, a reservoir provided with a dispensing valve equipped with a hollow control rod comprising a product inlet and a product outlet; the dispensing head comprises a push button for actuating the valve via the rod, at least two nozzles housed in the push button and at least two conduits connecting each nozzle respectively to the outlet of the rod.

Un distributeur de laque de ce type est décrit dans le document FR-A-2691383. Selon ce document, les axes des deux buses sont situés dans un même plan et forment entre eux un angle étroit compris entre 1° et 40°. Ces buses sont alimentées en produit par des conduits dont les axes sont parallèles entre eux. Ce distributeur délivre un spray dont la surface d'impact présente une répartition de produit de densité variable, risquant de modifier la mise en forme de la chevelure. Il ne permet pas la délivrance d'un spray homogène et doux. De plus, ce distributeur à un angle étroit entre les axes des buses est difficilement réalisable car il nécessite de fabriquer des buses fortement inclinées.A lacquer dispenser of this type is described in document FR-A-2691383. According to this document, the axes of the two nozzles are located in the same plane and form between them a narrow angle between 1 ° and 40 °. These nozzles are supplied with product by conduits whose axes are parallel to each other. This dispenser delivers a spray whose impact surface has a distribution of product of variable density, risking modifying the shaping of the hair. It does not allow the delivery of a homogeneous and soft spray. In addition, this distributor at a narrow angle between the axes of the nozzles is difficult to produce because it requires the manufacture of strongly inclined nozzles.

Il est également décrit dans US-A-3045925 un distributeur de deux produits contenus de façon séparés dans deux réservoirs. Chaque produit est pulvérisé sous forme de spray et le mélange des deux produits séparés est effectué par collision de deux sprays. Cette collision engendre alors un spray unique. Les orifices de pulvérisation sont chacun reliés à la sortie de la tige de valve du réservoir correspondant par un conduit rectiligne. Une tête de pulvérisation avec une telle dispositon des deux conduits rectilignes est difficile à fabriquer, notamment lors de la phase de démoulage d'une fabrication par moulage.
Par ailleurs, la collision des deux sprays de produits différents ne procure pas un spray unique homogène en produit, compte tenu d'un mauvais mélange des deux produits.It is also described in US-A-3045925 a distributor of two products contained separately in two tanks. Each product is sprayed in the form of a spray and the mixing of the two separate products is carried out by collision of two sprays. This collision then generates a single spray. The spray orifices are each connected to the outlet of the valve stem of the corresponding tank by a straight pipe. A spray head with such an arrangement of the two rectilinear conduits is difficult to manufacture, in particular during the demolding phase of a production by molding.
Furthermore, the collision of the two sprays of different products does not provide a single spray that is homogeneous in product, given the poor mixing of the two products.

La présente invention vise donc à remédier aux inconvénients mentionnés ci-dessus.The present invention therefore aims to remedy the drawbacks mentioned above.

La présente invention a pour but, surtout, de proposer une tête de distribution du genre défini précédemment, qui délivre un spray homogène. Elle a pour but également de fournir une tête de distribution qui délivre un spray doux et non diffus. Elle a aussi pour but de proposer une tête de distribution délivrant un spray présentant de bonnes propriétés de granulométrie des goutelettes de produit et de débit. Un autre but de l'invention est de fournir une tête de distribution qui soit simple à fabriquer.The present invention aims, above all, to propose a dispensing head of the kind defined above, which delivers a homogeneous spray. It also aims to provide a dispensing head which delivers a soft and non-diffuse spray. It also aims to provide a dispensing head delivering a spray having good particle size properties of the product droplets and flow. Another object of the invention is to provide a dispensing head which is simple to manufacture.

La demanderesse a découvert, de façon inattendue et surprenante, qu'un tel résultat pouvait être obtenu par la collision de deux ou plusieurs sprays sortant simultanément de deux ou plusieurs buses, chaque buse étant alimentée par un conduit ayant un profil particulier.The Applicant has discovered, unexpectedly and surprisingly, that such a result could be obtained by the collision of two or more sprays coming out simultaneously two or more nozzles, each nozzle being supplied by a conduit having a particular profile.

La tête de distribution de l'invention peut être utilisée pour la distribution de laque capillaire, l'impact du spray résultant sur les cheveux respectant la forme de la chevelure.The dispensing head of the invention can be used for dispensing hair spray, the impact of the resulting spray on the hair respecting the shape of the hair.

La présente invention a donc pour objet une tête de distribution d'un produit liquide sous forme d'aérosol comportant un bouton-poussoir muni d'un axe (X), au moins deux conduits logés dans le bouton-poussoir et au moins deux buses prévues dans le bouton-poussoir, caractérisée par le fait qu'au moins une partie de chaque conduit est radiale, qu'une autre partie du conduit est en communication avec la buse et est orientée parallèlement à un axe de la buse, de sorte que les sprays sortant de chaque buse se percutent pour fournir un spray unique et homogène.The present invention therefore relates to a dispensing head of a liquid product in the form of an aerosol comprising a push button provided with an axis (X), at least two conduits housed in the push button and at least two nozzles provided in the push button, characterized in that at least part of each conduit is radial, that another part of the conduit is in communication with the nozzle and is oriented parallel to an axis of the nozzle, so that the sprays coming out of each nozzle collide to provide a unique and homogeneous spray.

L'invention a encore pour objet un distributeur comportant un réservoir sous pression renfermant un produitliquide à distribuer sous forme d'aérosol, une valve de distribution de ce produit munie d'une tige creuse de commande de valve, comportant une entrée et une sortie, une tête de distribution munie d'un bouton-poussoir, de deux conduits et de deux buses, caractérisé par le fait que la tête de distribution est conforme à celle définie précédemment.The subject of the invention is also a dispenser comprising a pressure tank containing a liquid product to be dispensed in the form of an aerosol, a valve for dispensing this product provided with a hollow valve control rod, comprising an inlet and an outlet, a dispensing head provided with a push button, two conduits and two nozzles, characterized in that the dispensing head conforms to that defined above.

Selon l'invention, chaque conduit raccorde chaque buse à la sortie de la tige de valve.According to the invention, each conduit connects each nozzle to the outlet of the valve stem.

Avantageusement, la partie radiale est située sensiblement dans un plan transversal à l'axe longitudinal du bouton-poussoirAdvantageously, the radial part is located substantially in a plane transverse to the longitudinal axis of the push button.

Selon l'invention, chaque conduit peut comprendre une partie axiale ayant un axe parallèle à l'axe de la tige. Une extrémité de cette partie du conduit peut être reliée à la sortie de la tige creuse de valve.According to the invention, each conduit can comprise an axial part having an axis parallel to the axis of the rod. One end of this part of the conduit can be connected to the outlet of the hollow valve stem.

De préférence, le produit distribué par la tête de distribution est un monoproduit. On entend par monoproduit un produit qui est conditionné dans un réservoir unique équipé de la tête de pulvérisation selon l'invention. Dans ce cas, les parties axiales des deux conduits sont confondues.Preferably, the product dispensed by the dispensing head is a monoproduct. By monoproduct is meant a product which is packaged in a single reservoir equipped with the spray head according to the invention. In this case, the axial parts of the two conduits are combined.

De façon avantageuse, chaque buse a un axe orienté transversalement par rapport à l'axe longitudinal du bouton-poussoir, les axes des buses étant situés dans un même plan, en vue de faciliter la fabrication de la tête de distribution.Advantageously, each nozzle has an axis oriented transversely to the longitudinal axis of the push button, the axes of the nozzles being located in the same plane, in order to facilitate the manufacture of the dispensing head.

De préférence, les axes des buses forment entre eux un angle allant de 20° à 120°, et de préférence un angle de 60°, afin d'assurer la collision des particules des sprays.Preferably, the axes of the nozzles form between them an angle ranging from 20 ° to 120 °, and preferably an angle of 60 °, in order to ensure the collision of the particles of the sprays.

De préférence, l'axe de chaque buse est séparé de l'axe de la partie axiale du conduit d'une distance au moins égale à la longueur du pilier de la buse, additionnée de la largeur de la partie radiale du conduit. Cette distance de séparation facilite le moulage et le démoulage de la tête de distribution, même pour un petit angle entre les axes des buses.Preferably, the axis of each nozzle is separated from the axis of the axial part of the conduit by a distance at least equal to the length of the pillar of the nozzle, plus the width of the radial part of the conduit. This separation distance facilitates the molding and demolding of the dispensing head, even for a small angle between the axes of the nozzles.

Selon une première variante, la partie radiale de chaque conduit peut relier la partie axiale à l'autre partie du conduit en communication avec la buse. Elle peut être définie dans une seule et même pièce ou bien dans deux pièces distinctes. Dans ce cas, la partie radiale de chaque conduit peut comprendre un premier élément défini dans la même pièce que celle de la partie axiale du conduit et un deuxième élément défini dans une autre pièce et portant une des buses, les deux éléments étant liés entre eux par un moyen de liaison.According to a first variant, the radial part of each conduit can connect the axial part to the other part of the conduit in communication with the nozzle. It can be defined in a single room or in two separate rooms. In this case, the radial part of each conduit can comprise a first element defined in the same part as that of the axial part of the conduit and a second element defined in another part and carrying one of the nozzles, the two elements being linked together by a connecting means.

Avantageusement, l'extrémité de la partie radiale de chaque conduit est perpendiculaire à l'autre partie du conduit en communication avec la buse.Selon une deuxième variante, la partie axiale du conduit peut être reliée à l'autre partie du conduit en communication avec la buse par la partie radiale et par une partie incurvée, notamment flexible. Dans ce cas, Avantageusement, chaque buse est maintenue par un mât et une potence d'accrochage sur le bouton-poussoir. Un tel agencement facilite le démoulage de la tête de distribution et confère à cette dernière une esthétique futuriste.Advantageously, the end of the radial part of each conduit is perpendicular to the other part of the conduit in communication with the nozzle. According to a second variant, the axial part of the conduit can be connected to the other part of the conduit in communication with the nozzle by the radial part and by a curved part, in particular flexible. In this case, Advantageously, each nozzle is held by a mast and a hooking bracket on the push button. Such an arrangement facilitates the demolding of the dispensing head and gives it a futuristic aesthetic.

De préférence, la tête de distribution comporte deux buses. Celles-ci sont avantageusement identiques.Preferably, the dispensing head has two nozzles. These are advantageously identical.

L'invention consiste, mise à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question après, à propos d'exemples de réalisation décrits en référence aux dessins annexés, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below, with regard to embodiments described with reference to the appended drawings, but which are in no way intended limiting.

La figure 7 est une coupe partielle selon VII - VII du distributeur de la figure 6.FIG. 7 is a partial section on VII - VII of the dispenser of FIG. 6.

En se rapportant aux figures 1 à 3 annexées, on peut voir un distributeur désigné dans son ensemble par la référence 2, présentant un axe X de symétrie et comportant une valve de distribution 4 équipant un réservoir 6, généralement cylindrique, pressurisé à l'aide d'un gaz propulseur. Le réservoir contient, en outre, un produit liquide, par exemple cosmétique, à distribuer sous forme d'aérosol. Ce réservoir peut être équipé d'une poche contenant le produit, ou d'un piston sur lesquels agirait un gaz propulseur de façon indirecte.Referring to Figures 1 to 3 attached, we can see a distributor designated as a whole by the reference 2, having an axis X of symmetry and having a distribution valve 4 fitted to a reservoir 6, generally cylindrical, pressurized using of a propellant. The reservoir also contains a liquid product, for example a cosmetic product, to be dispensed in the form of an aerosol. This tank can be equipped with a pocket containing the product, or with a piston on which a propellant would act indirectly.

Le distributeur 2 comprend, de plus, un bouton-poussoir 8 fixé sur le réservoir 6 ou sur la partie supérieure de la valve 4. Ce bouton-poussoir comporte, suivant l'axe X, un pion 10 cylindrique solidaire de la paroi supérieure 8a du bouton-poussoir 8. Le pion 10 est traversé par un conduit axial 12.The distributor 2 further comprises a push button 8 fixed on the reservoir 6 or on the upper part of the valve 4. This push button comprises, along the axis X, a cylindrical pin 10 integral with the upper wall 8a of the push button 8. The pin 10 is crossed by an axial duct 12.

L'extrémité libre (du côté du réservoir) du conduit 12 comporte un alésage 14 de diamètre plus important que celui du conduit 12, de manière à former un logement pour recevoir, avec un léger serrage, l'extrémité libre d'une tige de commande 16 de la valve 4. Cette valve est une valve classique dont l'ouverture est commandée par enfoncement de la tige 16 selon l'axe X lors de l'application d'une poussée sur le bouton-poussoir. Cet axe constitue aussi l'axe longitudinal de la tige.The free end (on the reservoir side) of the conduit 12 has a bore 14 of larger diameter than that of the conduit 12, so as to form a housing for receiving, with a slight tightening, the free end of a rod of control 16 of valve 4. This valve is a conventional valve, the opening of which is controlled by pressing the rod 16 along the axis X during the application of a push on the push-button. This axis also constitutes the longitudinal axis of the rod.

La valve 4 comporte un corps 18 qui est serti, en partie haute, du côté de la tige de commande, dans une coupelle 20 fixée par sertissage ou dudgeonnage sur une ouverture circulaire pratiquée au sommet d'un dôme 6a du réservoir 6. Cette coupelle comporte un bord roulé 22 et coiffe l'extrémité supérieure du dôme 6a du réservoir 6. La partie inférieure du corps 18 de valve, située du côté opposé à la tige de commande 16, est munie d'une zone de raccordement 24, prolongée par un tube plongeur 26 s'étendant jusqu'au fond du réservoir 6.The valve 4 comprises a body 18 which is crimped, in the upper part, on the side of the control rod, in a cup 20 fixed by crimping or swaging on a circular opening made at the top of a dome 6a of the tank 6. This cup has a rolled edge 22 and covers the upper end of the dome 6a of the reservoir 6. The lower part of the valve body 18, situated on the side opposite to the control rod 16, is provided with a connection zone 24, extended by a dip tube 26 extending to the bottom of the tank 6.

L'extrémité libre 28 de la tige 16 constitue une sortie de produit de la tige, l'autre extrémité de la tige (non représentée) située dans le corps de valve 18 constitue l'entrée de produit de la tige.The free end 28 of the rod 16 constitutes a product outlet from the rod, the other end of the rod (not shown) located in the valve body 18 constitutes the product inlet from the rod.

Comme visible sur les figures 2, 2a et 3, le bouton-poussoir 8 comporte, selon l'invention, deux buses de pulvérisation 30a, 30b et deux conduits 11a, 11b. Chaque conduit 11a, 11b raccorde respectivement chaque buse 30a, 30b à la sortie 28 de la tige 16 de valve. Chaque buse 30a, 30b est une pièce rapportée sur le bouton-poussoir 8 et comporte, de façon connue, des canaux tourbillonnaires. Les parties du distributeur relatives à la première buse 30a porteront l'indice a et les parties relatives à la seconde buse 30b porteront l'indice b.As shown in Figures 2, 2a and 3, the push button 8 comprises, according to the invention, two spray nozzles 30a, 30b and two conduits 11a, 11b. Each conduit 11a, 11b respectively connects each nozzle 30a, 30b to the outlet 28 of the valve stem 16. Each nozzle 30a, 30b is an insert on the push button 8 and comprises, in known manner, vortex channels. The parts of the dispenser relating to the first nozzle 30a will bear the index a and the parts relating to the second nozzle 30b will bear the index b .

Chaque conduit 11a, 11b comprend une partie axiale, encore appelée conduit axial, 12a, 12b, une partie radiale, encore appelée conduit radial, 36a, 36b, et une partie 35a, 35b en communication respectivement avec chaque buse 30a, 30b.Each conduit 11a, 11b comprises an axial part, also called an axial conduit, 12a, 12b, a radial part, also called a radial conduit, 36a, 36b, and a part 35a, 35b in communication with each nozzle 30a, 30b respectively.

Le bouton-poussoir comporte, en outre, deux piliers 32a, 32b, de section circulaire, logés dans des manchons 35a, 35b et définissent avec ces derniers une chambre annulaire 34a, 34b respectivement alimentée par la partie 35a, 35b du conduit 11a, 11b. Cette partie 35a, 35b rectiligne du conduit est reliée au conduit radial rectiligne 36a, 36b communiquant avec le conduit axial 12. Les piliers comportent des axes de symétrie A-A, B-B perpendiculaires à l'axe X. Chaque pilier 32a, 32b présente une face avant 44a, 44b. Chaque partie 35a, 35b de chaque conduit 11a, 11b débouche dans la chambre annulaire 34a, 34b des buses 30a, 30b et est parallèle à l'axe A-A, B-B de la buse 30a, 30b.The push button further comprises two pillars 32a, 32b, of circular section, housed in sleeves 35a, 35b and define with these an annular chamber 34a, 34b respectively supplied by the part 35a, 35b of the conduit 11a, 11b. This rectilinear part 35a, 35b of the duct is connected to the rectilinear radial duct 36a, 36b communicating with the axial duct 12. The pillars have axes of symmetry AA, BB perpendicular to the axis X. Each pillar 32a, 32b has a front face 44a, 44b. Each part 35a, 35b of each conduit 11a, 11b opens into the annular chamber 34a, 34b of the nozzles 30a, 30b and is parallel to the axis AA, BB of the nozzle 30a, 30b.

Les buses 30a, 30b comportent respectivement une jupe périphérique 38a, 38b qui vient s'insérer dans la chambre annulaire 34a, 34b contre la paroi 40a, 40b interne des manchons 35a, 35b. Chaque buse comporte, en outre, une face arrière 42a, 42b, parallèle à la face avant 44a, 44b des piliers 32a, 32b qui vient s'appliquer contre elle.
Pour la pulvérisation du produit à travers les buses 28a, 28b, celles-ci comportent respectivement un orifice 46a, 46b selon les axes A-A et B-B.The nozzles 30a, 30b respectively comprise a peripheral skirt 38a, 38b which is inserted into the annular chamber 34a, 34b against the internal wall 40a, 40b of the sleeves 35a, 35b. Each nozzle further comprises a rear face 42a, 42b, parallel to the front face 44a, 44b of the pillars 32a, 32b which comes to bear against it.
For spraying the product through the nozzles 28a, 28b, these respectively have an orifice 46a, 46b along the axes AA and BB.

Les axes A-A, B-B des buses 28a, 28b sont situés dans un même plan perpendiculaire à l'axe X. Sur la figure 2, les axes A-A et B-B forment, entre eux, un angle de 60°.The axes A-A, B-B of the nozzles 28a, 28b are situated in the same plane perpendicular to the axis X. In FIG. 2, the axes A-A and B-B form, between them, an angle of 60 °.

Comme visible sur la figure 2, l'axe A-A, B-B la buse 30a, 30b est séparé de l'axe X du conduit central 12 d'une distance d qui est au moins égale à la longueur L du pilier 32a, 32b additionnée de la largeur I du conduit radial 36a, 36b (d ≥ L + I).As visible in FIG. 2, the axis AA, BB the nozzle 30a, 30b is separated from the axis X of the central duct 12 by a distance d which is at least equal to the length L of the pillar 32a, 32b plus the width I of the radial duct 36a, 36b (d ≥ L + I).

Par ailleurs, le bouton-poussoir 8 est lié à une bague de fixation 48 par une charnière film 50. La bague de fixation 48 comporte un plateau 51, une jupe externe 52 dont l'extrémité inférieure 52a est en contact avec la paroi du réservoir 6 et une jupe interne 54 qui est encliquetée sur le bord annulaire 22 de la coupelle 20 du réservoir 6. Des reliefs 56 liés à la jupe interne 54 et en contact avec le bord annulaire 22 de la coupelle 20 assurent la bonne stabilité de la bague de fixation 48 sur le réservoir 6.Furthermore, the push-button 8 is linked to a fixing ring 48 by a film hinge 50. The fixing ring 48 comprises a plate 51, an external skirt 52 whose lower end 52a is in contact with the wall of the reservoir 6 and an internal skirt 54 which is snapped onto the annular edge 22 of the cup 20 of the reservoir 6. Reliefs 56 linked to the internal skirt 54 and in contact with the annular edge 22 of the cup 20 ensure good stability of the ring mounting 48 on the tank 6.

Le bouton-poussoir comporte une jupe 58 sensiblement cylindrique selon l'axe X munie d'une languette de commande 60 du distributeur qui s'étend dans un plan sensiblement transversal à l'axe X.The push button comprises a skirt 58 substantially cylindrical along the axis X provided with a control tongue 60 of the dispenser which extends in a plane substantially transverse to the axis X.

Lorsqu'une poussée est appliquée sur la languette 60 du bouton-poussoir 8, le produit contenu dans le réservoir 6 est pulvérisé à l'extérieur via le conduit 12, les conduits radiaux 36a, 36b et les orifices 46a, 46b des buses 30a, 30b, sous l'action du gaz propulseur.When a push is applied to the tongue 60 of the push button 8, the product contained in the reservoir 6 is sprayed outside via the conduit 12, the radial conduits 36a, 36b and the orifices 46a, 46b of the nozzles 30a, 30b, under the action of the propellant gas.

Comme le montre la figure 3, les deux sprays sa, sb sortant des deux buses se rencontrent en un point de convergence P puis forment un spray unique divergent S. La collision des particules des sprays sa, sb provoque une diminution de leur énergie cinétique générant un spray S d'une force d'impact plus faible que celle des sprays sa et sb ; ainsi, le spray S est doux. Le spray S a une section transversale légèrement ovale et présente une densité de produit quasi-homogène. Son apparence est identique à celle des sprays monobuse de l'art antérieur. Le débit du spray S est légèrement supérieur à celui d'un spray obtenu avec une seule buse, ce qui permet de conserver un bon maintien de la coiffure lorsque le distributeur est utilisé pour l'application de laque capillaire.As shown in FIG. 3, the two sprays s a , s b leaving the two nozzles meet at a point of convergence P then form a single divergent spray S. The collision of the particles of the sprays s a , s b causes a decrease in their kinetic energy generating a spray S with a lower impact force than that of the sprays s a and s b ; thus, spray S is soft. Spray S has a slightly oval cross-section and has an almost homogeneous product density. Its appearance is identical to that of the single-nozzle sprays of the prior art. The flow rate of the spray S is slightly higher than that of a spray obtained with a single nozzle, which makes it possible to maintain good hold of the hairstyle when the distributor is used for the application of hair spray.

Sur la figure 4, les éléments identiques ou jouant des rôles analogues à des éléments déjà décrits sont désignés par les mêmes références numériques. Leur description ne sera pas reprise ou sera effectuée succinctement.In FIG. 4, the elements which are identical or which play roles analogous to the elements already described are designated by the same reference numerals. Their description will not be repeated or will be made succinctly.

Cette figure 4 montre un distributeur qui se distingue de celui de la figure 2 par le fait que les conduits radiaux 36a, 36b comportent deux éléments 62a, 64a, 62b, 64b liés entre eux par un moyen de liaison 66a, 66b. Le premier élément 62a, 62b est défini dans la même pièce que celle du conduit central 12. Le second élément 64a, 64b porte la buse 30a, 30b. Le moyen de liaison 66a, 66b comporte un jonc d'étanchéité 68a, 68b porté par le deuxième élément 64a, 64b et une rigole 70a, 70b située à l'intérieur du premier élément 62a, 62b, le jonc 68a, 68b étant claqué dans la rigole 70a, 70b. Cet agencement facilite le démoulage des pièces du bouton-poussoir.This FIG. 4 shows a distributor which differs from that of FIG. 2 by the fact that the radial conduits 36a, 36b comprise two elements 62a, 64a, 62b, 64b linked together by a connecting means 66a, 66b. The first element 62a, 62b is defined in the same part as that of the central duct 12. The second element 64a, 64b carries the nozzle 30a, 30b. The connecting means 66a, 66b comprises a sealing ring 68a, 68b carried by the second element 64a, 64b and a channel 70a, 70b located inside the first element 62a, 62b, the rod 68a, 68b being slammed in channel 70a, 70b. This arrangement facilitates the release of the parts of the push button.

En se reportant aux figures 5 à 7, on peut voir une autre variante de réalisation du distributeur selon l'invention. Comme précédemment, les éléments différents de ceux de la figure 1 porteront des références additionnées de 100.
Les différences portent essentiellement sur la forme des conduits.Referring to Figures 5 to 7, we can see another alternative embodiment of the dispenser according to the invention. As before, the elements different from those of FIG. 1 will bear references added to 100.
The differences relate essentially to the shape of the conduits.

Ainsi, la figure 5 montre, avant maintien des buses, un bouton-poussoir dont les conduits 111a, 111b sont alignés selon un axe Y orthogonal à l'axe X et parallèles aux parties 135a, 135b du conduit. Les extrémités 37a, 37b de ces conduits radiaux, sont sensiblement parallèles respectivement à l'axe A-A, B-B de la buse 30a, 30b. Un tel agencement permet de réaliser le bouton-poussoir par moulage d'une seule pièce, et notamment des conduits radiaux, des manchons et des piliers.Thus, Figure 5 shows, before holding the nozzles, a push button whose conduits 111a, 111b are aligned along an axis Y orthogonal to the axis X and parallel to the parts 135a, 135b of the conduit. The ends 37a, 37b of these radial conduits are substantially parallel respectively to the axis A-A, B-B of the nozzle 30a, 30b. Such an arrangement makes it possible to produce the push button by molding in one piece, and in particular radial conduits, sleeves and pillars.

Le plateau 51 de la bague de fixation 48 comporte, dans ce mode de réalisation, des mâts 74a, 74b et des potences d'accrochage 76a, 76b dont la hauteur s'étend dans une direction sensiblement parallèle à l'axe X. Ces mâts et potences constituent un moyen d'accrochage des buses de façon à les orienter dans une configuration permettant d'obtenir le résultat recherché pour le produit pulvérisé.The plate 51 of the fixing ring 48 comprises, in this embodiment, masts 74a, 74b and hooking brackets 76a, 76b whose height extends in a direction substantially parallel to the axis X. These masts and brackets constitute a means of hooking the nozzles so as to orient them in a configuration making it possible to obtain the desired result for the sprayed product.

Comme illustré à la figure 6, le conduit 111a, 111b est défini dans une pièce souple et est déformé en plaçant chaque buse 30a, 30b dans l'espace situé entre le mât 74a, 74b et la potence d'accrochage 76a, 76b. Le conduit 111a, 111b présente une partie radiale 136a, 136b qui débouche dans le conduit axial 12. Bien que non représenté sur les figures, il est préférable que la paroi de chaque conduit 111a, 111b n'ait pas une épaisseur constante sur une même section, de façon à permettre une bonne déformation du conduit.As illustrated in FIG. 6, the conduit 111a, 111b is defined in a flexible part and is deformed by placing each nozzle 30a, 30b in the space between the mast 74a, 74b and the attachment bracket 76a, 76b. The conduit 111a, 111b has a radial portion 136a, 136b which opens into the axial conduit 12. Although not shown in the figures, it is preferable that the wall of each conduit 111a, 111b does not have a constant thickness over the same section, so as to allow good deformation of the conduit.

La figure 7 montre la façon dont est maintenue la buse 30a par le mât 74a et la potence d'accrochage 76a. Cette dernière présente une avancée 78a perpendiculaire à l'axe de la potence et permet de maintenir en position la buse 30a. La pièce définissant les conduits radiaux se trouve, à chacune de ses extrémités, bloquée entre le mat et la potence.Figure 7 shows how the nozzle 30a is held by the mast 74a and the hooking bracket 76a. The latter has a projection 78a perpendicular to the axis of the bracket and keeps the nozzle 30a in position. The part defining the radial conduits is, at each of its ends, blocked between the mast and the stem.
