Abstract

The dispenser has a distribution valve (4) for a liq. prods., e.g. hair lacquer, connected through a hollow control stem (10) to a pressure cap (8) with duct (36a, 36b) leading to two separate outlet nozzles (28a,28b). The two nozzles are designed to produce different sprays, e.g. the first producing a narrow spray for the mechanical effect of positioning the hair, and the second a broad dispensing spray. The two ducts (38a,38b) in the pressure cap are linked to annular chambers (34a,34b) in the nozzles; the first nozzle has a cylindrical orifice (48a) between 0.2 and 1 mm. in dia., and the second a divergent orifice (48b) with its greatest section measuring 0.3-1.2,mm, giving sprays with angles of 5-20 degrees and 20-60 degrees respectively.

Description

L'invention est relative à un distributeur pour la distribution d'un produit liquide sous l'action d'un gaz propulseur, ce distributeur comprenant un récipient formant réservoir pour le produit. Le distributeur peut notamment être utilisé dans les domaines cosmétiques pour la distribution d'une laque capillaire, d'une lotion anti-poux, pharmaceutique pour la distribution de répulsifs pour insectes, agricoles pour la distribution d'insecticides.The invention relates to a dispenser for dispensing a liquid product under the action of a propellant, this dispenser comprising a container forming a reservoir for the product. The dispenser can in particular be used in the cosmetic fields for the distribution of a hair spray, an anti-lice lotion, pharmaceutical for the distribution of insect repellents, agricultural for the distribution of insecticides.

Le distributeur de l'invention comprend, de façon connue, un récipient muni d'une valve de distribution et qui contient le produit à pulvériser, la valve étant équipée d'une tige creuse de commande comportant une entrée de produit et une sortie de produit ; un bouton poussoir pour actionner la valve via la tige ; une première et une deuxième buses prévues dans le bouton-poussoir, un premier et un deuxième conduits raccordant respectivement la première et la deuxième buses à la sortie de la tige.The dispenser of the invention comprises, in known manner, a container provided with a dispensing valve and which contains the product to be sprayed, the valve being equipped with a hollow control rod comprising a product inlet and a product outlet ; a push button for actuating the valve via the rod; first and second nozzles provided in the push button, first and second conduits connecting the first and second nozzles respectively to the outlet of the rod.

Un distributeur de laque de ce genre a été décrit dans le modèle d'utilité allemand MU 70 42 354. Les deux sprays délivrés par deux buses identiques se mélangent pendant la pulvérisation sans divergence excessive, ce qui permet de limiter la production de brume et donc de diminuer le gaspillage de produit dans l'atmosphère.
Naturellement, les cheveux sont regroupés librement en mèches très souples. Or, lorsqu'on utilise un tel distributeur pour la distribution de laque capillaire, les deux sprays déposent le produit sur les cheveux en ne maintenant que la forme initiale de la chevelure après le coiffage de celle-ci : autrement dit, les cheveux sont liés les uns aux autres. Ce distributeur ne permet donc pas, lors de la pulvérisation, de séparer les cheveux en mèches de façon à obtenir un résultat de mise en forme conforme au naturel.A lacquer dispenser of this kind has been described in the German utility model MU 70 42 354. The two sprays delivered by two identical nozzles mix during spraying without excessive divergence, which makes it possible to limit the production of mist and therefore reduce the waste of product in the atmosphere.
Naturally, the hair is grouped freely in very flexible locks. However, when using such a distributor for the distribution of hair spray, the two sprays deposit the product on the hair while maintaining only the initial shape of the hair after styling it: in other words, the hair is linked each other. This dispenser therefore does not allow, during spraying, to separate the hair into locks so as to obtain a shaping result which conforms to the natural.

La présente invention vise donc à remédier à l'inconvénient mentionné ci-dessus.The present invention therefore aims to remedy the drawback mentioned above.

La présente invention a pour but, surtout, de proposer un distributeur du genre défini précédemment, qui permet de délivrer un spray générant une mise en forme et une tenue naturelles de la chevelure.The present invention aims, above all, to propose a dispenser of the kind defined above, which makes it possible to deliver a spray generating a natural shaping and holding of the hair.

La demanderresse a découvert, de façon inattendue et surprenante, qu'un tel résultat pouvait être obtenu par la délivrance simultanée d'un spray puissant à effet mécanique apte à pousser la chevelure pour créer un creux et déposer du produit dans ce creux, et d'un spray doux pour déposer le produit sur les deux bords du creux.The Applicant has discovered, unexpectedly and surprisingly, that such a result could be obtained by the simultaneous delivery of a powerful spray with mechanical effect capable of pushing the hair to create a hollow and deposit product in this hollow, and d '' a gentle spray to deposit the product on both edges of the hollow.

La présente invention a donc pour objet un distributeur comportant une valve de distribution d'un produit liquide à distribuer sous la forme d'un aérosol à l'aide d'un gaz propulseur, cette valve étant montée sur un récipient contenant le liquide et étant munie d'une tige creuse de commande comportant une entrée de produit et une sortie de produit, un bouton-poussoir pour actionner la valve via la tige, une première et une deuxième buses étant prévues dans le bouton-poussoir, un premier et un deuxième conduits raccordant respectivement la première et la deuxième buses à la sortie de la tige, caractérisé par le fait que la première buse est une buse apte à délivrer un spray à effet mécanique et que la deuxième buse est une buse apte à délivrer un spray de produit.The present invention therefore relates to a dispenser comprising a valve for dispensing a liquid product to be dispensed in the form of an aerosol using a propellant, this valve being mounted on a container containing the liquid and being provided with a hollow control rod comprising a product inlet and a product outlet, a push button for actuating the valve via the stem, a first and a second nozzle being provided in the push button, a first and a second conduits connecting the first and second nozzles respectively to the outlet of the rod, characterized in that the first nozzle is a nozzle capable of delivering a spray with mechanical effect and the second nozzle is a nozzle capable of delivering a spray of product.

Selon l'invention, la première buse est une buse apte à délivrer un spray étroit et la deuxième buse est une buse apte à délivrer un spray large. Selon l'invention, le spray mécanique forme par exemple un angle total allant de 5° à 20° et le spray de produit forme par exemple un angle total allant de 20 ° à 60 °.According to the invention, the first nozzle is a nozzle capable of delivering a narrow spray and the second nozzle is a nozzle capable of delivering a wide spray. According to the invention, the mechanical spray forms, for example, a total angle ranging from 5 ° to 20 ° and the product spray forms, for example, a total angle ranging from 20 ° to 60 °.

De préférence, le deuxième conduit communique avec une chambre annulaire délimitée par un élément en forme de pilier ayant une face avant plaquée contre une face interne de la deuxième buse, la face avant du pilier étant distante de la face interne de la deuxième buse d'une distance d2 allant de 0 mm à 0,05 mm.Preferably, the second conduit communicates with an annular chamber delimited by a pillar-shaped element having a front face pressed against an internal face of the second nozzle, the front face of the pillar being distant from the internal face of the second nozzle. a distance d 2 ranging from 0 mm to 0.05 mm.

Par ailleurs, le premier conduit communique de préférence avec une chambre annulaire délimitée par un élément en forme de pilier ayant une face avant plaquée contre une face interne de la première buse, la face avant du pilier étant distante de la face interne de la première buse d'une distance d1 supérieure à d2, telle que par exemple la différence d1 - d2 va de 0,05 mm à 0,3 mm.Furthermore, the first conduit preferably communicates with an annular chamber delimited by a pillar-shaped element having a front face pressed against an internal face of the first nozzle, the front face of the pillar being distant from the internal face of the first nozzle. from a distance d 1 greater than d 2 , such as for example the difference d 1 - d 2 ranges from 0.05 mm to 0.3 mm.

Avantageusement, la première buse peut être munie d'un orifice de forme cylindrique, selon un axe sensiblement parallèle à l'axe du spray à effet mécanique, mais une autre forme pourrait être envisagée(elliptique). L'orifice de forme cylindrique de la première buse peut avoir par exemple un diamètre allant de 0,2 mm à 1 mm.Advantageously, the first nozzle may be provided with an orifice of cylindrical shape, along an axis substantially parallel to the axis of the spray with mechanical effect, but another shape could be envisaged (elliptical). The cylindrical orifice of the first nozzle may for example have a diameter ranging from 0.2 mm to 1 mm.

Selon un mode particulier de l'invention, la deuxième buse peut être munie d'une face externe et d'un orifice de forme évasée, selon un axe sensiblement parallèle à l'axe du spray de produit, la section de plus grand diamètre de l'orifice de forme évasée étant située sur la face externe de la première buse. Tout autre forme pourrait être envisagée.According to a particular embodiment of the invention, the second nozzle may be provided with an external face and an orifice of flared shape, along an axis substantially parallel to the axis of the product spray, the section of larger diameter of the flared orifice being located on the external face of the first nozzle. Any other form could be considered.

L'orifice évasé de la deuxième buse peut avoir une section de plus grand diamètre allant de 0,3 mm à 1,2 mm.The flared orifice of the second nozzle may have a larger diameter section ranging from 0.3 mm to 1.2 mm.

Selon une variante de l'invention, le gaz propulseur peut être pulvérisé par la première buse pour former le spray à effet mécanique. Dans ce cas, la tige de valve est constituée de deux cylindres coaxiaux.According to a variant of the invention, the propellant gas can be sprayed by the first nozzle to form the spray with mechanical effect. In this case, the valve stem consists of two coaxial cylinders.

Selon une autre variante de l'invention, le liquide peut être pulvérisé simultanément par les deux buses.According to another variant of the invention, the liquid can be sprayed simultaneously by the two nozzles.

Selon un aspect intéressant de l'invention, la tige a un axe longitudinal et les deux buses sont situées l'une au-dessus de l'autre par rapport à cet axe longitudinal.According to an interesting aspect of the invention, the rod has a longitudinal axis and the two nozzles are located one above the other with respect to this longitudinal axis.

Par ailleurs, la première buse peut être décalée de la deuxième buse par rapport à l'axe longitudinal de la tige.Furthermore, the first nozzle can be offset from the second nozzle relative to the longitudinal axis of the rod.

Pour mieux faire comprendre l'objet de la présente invention, on va en décrire, à titre d'exemple purement illustratif et nullement limitatif, deux modes de réalisation représentés sur les figures annexées.To better understand the object of the present invention, there will be described, by way of purely illustrative and in no way limitative, two embodiments shown in the appended figures.

La figure 1 est une coupe axiale d'un distributeur conforme à une première variante de l'invention.Figure 1 is an axial section of a dispenser according to a first variant of the invention.

La figure 2 est une vue de dessus d'un distributeur conforme à une deuxième variante de l'invention.Figure 2 is a top view of a dispenser according to a second variant of the invention.

La figure 3 est une coupe axiale d'un distributeur au repos conforme à une troisième variante de l'invention.Figure 3 is an axial section of a dispenser at rest according to a third variant of the invention.

La figure 4 représente une coupe analogue à celle de la figure 3, le distributeur étant montré en cours de pulvérisation.Figure 4 shows a section similar to that of Figure 3, the dispenser being shown during spraying.

En se rapportant à la figure 1 annexée, on peut voir un distributeur désigné dans son ensemble par la référence 2, comportant une valve de distribution 4 équipant un récipient 6, généralement cylindrique, sous pression à l'aide d'un gaz propulseur, et présentant un axe X de symétrie. Le récipient 6 contient, en outre, un produit liquide par exemple cosmétique à distribuer sous forme d' aérosol. Il est également possible d'utiliser un réservoir équipé d'une poche contenant le produit ou d'un piston sur lequel agit un gaz propulseur de façon indirecte.Referring to the appended FIG. 1, one can see a dispenser designated as a whole by the reference 2, comprising a dispensing valve 4 fitted to a container 6, generally cylindrical, under pressure using a propellant, and having an X axis of symmetry. The container 6 also contains a liquid product, for example a cosmetic product, to be dispensed in the form of an aerosol. It is also possible to use a reservoir equipped with a pocket containing the product or with a piston on which a propellant acts indirectly.

Le dispositif 2 comprend, de plus, un bouton-poussoir 8 fixé sur le récipient 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 device 2 further comprises a push button 8 fixed on the container 6 or on the upper part of the valve 4. This push button comprises, along the axis X, a cylindrical pin 10 secured to 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 apte à 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, cet axe constituant aussi l'axe longitudinal de la tige. 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 récipient 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.
L'extrémité libre 19 de la tige 16 constitue la sortie de produit de la tige, l'autre extrémité de la tige (non representée) située dans le corps de valve 18 constitue l'entrée de produit 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 capable of receiving, with a slight tightening, the free end of a rod 16 for controlling the valve 4. This valve is a conventional valve, the opening of which is controlled by pressing the rod 16 along the axis X, this axis also constituting the longitudinal axis of the rod. 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 container 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.
The free end 19 of the rod 16 constitutes the 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.

Le bouton-poussoir 8 comporte, selon l'invention, une première buse de pulvérisation 28a et une deuxième buse de pulvérisation 28b. Chaque buse 28a, 28b est une pièce rapportée sur le bouton-poussoir 8 et comporte, de façon connue, des canaux d'alimentation tourbillonnaires. Les parties du distributeur relatives à la première buse 28a porteront l'indice a et les parties relatives à la seconde buse 28b porteront l'indice b.According to the invention, the push button 8 comprises a first spray nozzle 28a and a second spray nozzle 28b. Each nozzle 28a, 28b is an insert on the push-button 8 and comprises, in known manner, vortex supply channels. Distributor parts relating to the first nozzle 28a will bear the index a and the parts relating to the second nozzle 28b will bear the index b .

Le bouton-poussoir 8 comporte, en outre, deux éléments 32a, 32b en forme de pilier, de section circulaire dont la paroi délimite une chambre annulaire 34a, 34b respectivement alimentée par un canal 36a, 36b communiquant avec le conduit 12. Les piliers comportent des axes de symétrie A-A, B-B parallèles entre eux et perpendiculaires à l'axe X.The push button 8 further comprises two elements 32a, 32b in the form of a pillar, of circular section, the wall of which delimits an annular chamber 34a, 34b respectively supplied by a channel 36a, 36b communicating with the conduit 12. The pillars comprise axes of symmetry AA, BB parallel to each other and perpendicular to the axis X.

Les buses 28a, 28b comportent respectivement une jupe périphérique 38a, 38b qui vient s'insérer dans la chambre annulaire 34a, 34b, contre la paroi 40a, 40b exterieure de ladite chambre 34a, 34b. Chaque buse 28a, 28b comporte également une face interne 42a, 42b et une face externe 44a, 44b. Chaque pilier 32a, 32b présente une face avant 46a, 46b parallèle à la face interne de la buse 28a, 28b qui vient s'appliquer contre elle.The nozzles 28a, 28b respectively comprise a peripheral skirt 38a, 38b which is inserted in the annular chamber 34a, 34b, against the wall 40a, 40b outside of said chamber 34a, 34b. Each nozzle 28a, 28b also has an internal face 42a, 42b and an external face 44a, 44b. Each pillar 32a, 32b has a front face 46a, 46b parallel to the internal face of the nozzle 28a, 28b which comes to bear against it.

La face interne 42a de la première buse 28a est distante de la face avant 46a du pilier 32a d'une distance d1 qui peut être par exemple de 0,15 mm. De même, la face interne 42b de la deuxième buse 28b est distante de la face avant 46b du pilier 32b d'une distance d2 qui peut être par exemple de 0 mm. Sur la figure 2, la distance d2 a été exagérée pour une meilleure compréhension.La distance d1 est supérieure à la distance d2, comme visible plus nettement sur la figure 2.The internal face 42a of the first nozzle 28a is distant from the front face 46a of the pillar 32a by a distance d 1 which can be for example 0.15 mm. Likewise, the internal face 42b of the second nozzle 28b is distant from the front face 46b of the pillar 32b by a distance d 2 which can be for example 0 mm. In figure 2, the distance d 2 has been exaggerated for a better understanding. The distance d 1 is greater than the distance d 2 , as can be seen more clearly in figure 2.

Pour la pulvérisation du produit à travers les buses 28a, 28b, celles-ci comportent respectivement un orifice 48a, 48b.
L'orifice 48a de la première buse 28a présente une forme cylindrique selon l'axe A-A. Le diamètre de l'orifice 48a peut être par exemple de 0,4 mm. L'orifice 48b de la deuxième buse 28b présente une forme évasée, selon l'axe B-B, la section de plus grand diamètre étant située sur la face externe 44b de la buse 28b. La section de plus grand diamètre peut être par exemple de 0,8 mm et la section de plus petit diamètre de 0,3 mm.For spraying the product through the nozzles 28a, 28b, these respectively have an orifice 48a, 48b.
The orifice 48a of the first nozzle 28a has a cylindrical shape along the axis AA. The diameter of the orifice 48a can be for example 0.4 mm. The orifice 48b of the second nozzle 28b has a flared shape, along the axis BB, the section of larger diameter being located on the external face 44b of the nozzle 28b. The section with the largest diameter may for example be 0.8 mm and the section with the smallest diameter 0.3 mm.

Comme visible sur la figure 1, la première buse 28a est située au dessus de la deuxième buse 28b selon l'axe longitudinal X-X de la tige de commande 16 de la valve 4. Autrement dit, les axes A-A, B-B des buses 28a, 28b sont situés dans un même plan passant par l'axe X-X.As visible in FIG. 1, the first nozzle 28a is located above the second nozzle 28b along the longitudinal axis XX of the control rod 16 of the valve 4. In other words, the axes AA, BB of the nozzles 28a, 28b are located in the same plane passing through the axis XX.

Lorsqu'un effort est appliqué sur le bouton-poussoir 8, le produit contenu dans le récipient 6 est pulvérisé à l'extérieur à travers le conduit 12, les canaux 36a, 36b et les orifices 48a, 48b des buses 28a, 28b, sous l'action du fluide propulseur. La première buse 28a délivre un spray étroit de produit, à effet mécanique, tandis que la deuxième buse délivre un spray de produit large et doux. Ainsi, si l'on utilise un tel distributeur pour l'application de laque capillaire sur une chevelure, le spray à effet mécanique sert essentiellement à créer des creux dans la chevelure qui seront fixés à l'aide du produit pulvérisé et le spray large et doux sert à déposer le produit sur les bords des creux ainsi créés. On obtient donc, lors de l'application de la laque capillaire avec un tel dispositif une mise en forme naturelle de la chevelure et une tenue de cette mise en forme.When a force is applied to the push button 8, the product contained in the container 6 is sprayed outside through the conduit 12, the channels 36a, 36b and the orifices 48a, 48b of the nozzles 28a, 28b, under the action of the propellant. The first nozzle 28a delivers a narrow spray of product, with mechanical effect, while the second nozzle delivers a spray of broad and soft product. Thus, if such a dispenser is used for applying hair spray to hair, the spray with mechanical effect essentially serves to create hollows in the hair which will be fixed with the sprayed product and the wide spray and soft serves to deposit the product on the edges of the hollows thus created. We therefore obtain, during the application of the hair spray with such a device, a natural shaping of the hair and a holding of this shaping.

Sur la figure 2, les éléments identiques ou jouant des rôles analogues à des éléments déjà décrits à propos des figures précédentes sont désignés par les mêmes références- numériques, éventuellement majorées de cent. Leur description ne sera pas reprise ou sera effectuée succinctement.In FIG. 2, the elements identical or playing roles analogous to elements already described with respect to the preceding figures are designated by the same reference numerals, possibly increased by one hundred. Their description will not be repeated or will be made succinctly.

La figure 2 montre un distributeur qui se distingue de celui de la figure 1 par le fait que les deux buses 28a, 28b sont situées dans un même plan perpendiculaire à l'axe longitudinal X-X. En outre, les canaux 136a et 136b sont aussi dans un même plan perpendiculaire à l'axe X-X. Le fonctionnement de ce dispositif est similaire à celui représenté à la figure 1.Figure 2 shows a dispenser which differs from that of Figure 1 in that the two nozzles 28a, 28b are located in the same plane perpendicular to the longitudinal axis X-X. In addition, the channels 136a and 136b are also in the same plane perpendicular to the axis X-X. The operation of this device is similar to that shown in Figure 1.

En se reportant aux figures 3 et 4, 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 200.Referring to Figures 3 and 4, 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 with 200.

Le pion 210 du bouton-poussoir 208 est traversé par un conduit 50 et un conduit annulaire 52 coaxiaux. Le conduit 50 communique avec le canal 236a relié à la première buse 228a. Le conduit annulaire 52 communique avec le canal 236b relié à la deuxième buse 228b.The pin 210 of the push button 208 is traversed by a conduit 50 and an annular conduit 52 coaxial. The conduit 50 communicates with the channel 236a connected to the first nozzle 228a. The annular conduit 52 communicates with the channel 236b connected to the second nozzle 228b.

La valve 204 est constituée d'une tige 216, d'un corps de valve 218, d'un ressort 54, d'un joint principal 56 et d'un joint secondaire 58.The valve 204 consists of a rod 216, a valve body 218, a spring 54, a main seal 56 and a secondary seal 58.

La tige de valve 216 est constituée de deux cylindres concentriques : un premier cylindre externe 60 et un deuxième cylindre interne 62. Chaque cylindre 60, 62 débouche respectivement par une conduite radiale 64, 66 à l'intérieur du corps de valve 218. L'extrémité libre de la conduite 66 constitue l'entrée 217 de produit de la tige 216. L'extrémité libre du cylindre interne 62 constitue la sortie 219 de produit de la tige 216.
La tige comporte également à sa base une collerette supérieure 68, une collerette inférieure 69 pourvue d'un cône 70 dont la pointe est dirigée vers le récipient.The valve stem 216 consists of two concentric cylinders: a first external cylinder 60 and a second internal cylinder 62. Each cylinder 60, 62 opens respectively by a radial pipe 64, 66 inside the valve body 218. The free end of the pipe 66 constitutes the product inlet 217 of the rod 216. The free end of the internal cylinder 62 constitutes the product outlet 219 of the rod 216.
The rod also has at its base an upper flange 68, a lower flange 69 provided with a cone 70 whose tip is directed towards the container.

Le corps de valve 218 comporte, dans sa partie inférieure, une ouverture 72 et une gorge annulaire 74. Une première extrémité du ressort 54 vient se loger dans la gorge 74 de façon à être maintenu en place. L'autre extrémité du ressort 54 est en contact avec la partie inférieure de la tige de valve 216. Le cône 70 permet de maintenir centré le ressort 54 dans le corps de valve 218.
Le corps de valve 218 comporte également, dans sa partie supérieure, un orifice 76 et un épaulement 78.The valve body 218 has, in its lower part, an opening 72 and an annular groove 74. A first end of the spring 54 is received in the groove 74 so as to be held in place. The other end of the spring 54 is in contact with the lower part of the valve stem 216. The cone 70 keeps the spring 54 centered in the valve body 218.
The valve body 218 also has, in its upper part, an orifice 76 and a shoulder 78.

Le corps de valve 218 est serti sur la coupelle 80 de valve. Le joint principal 56 est en contact avec le dessous de la coupelle 80, avec le dessus de la partie supérieure 82 du corps de valve et avec le dessus de la collerette supérieure 68 de la tige de valve 216, de façon étanche par l'action du ressort 54.The valve body 218 is crimped onto the valve cup 80. The main seal 56 is in contact with the underside of the cup 80, with the top of the upper part 82 of the valve body and with the top of the upper flange 68 of the valve stem 216, sealingly by the action spring 54.

Le joint secondaire 58 est placé entre le joint principal 56 et l'épaulement 78 du corps de valve 218, en contact étanche avec la collerette inférieure 69 de la tige 216 sous l'action du ressort 54. Il comporte à sa partie supérieure une ou plusieurs rigoles 84 disposés radialement par rapport à l'axe longitudinal de la tige 216. Un jeu 86 existe entre la paroi interne 87 de l'épaulement 78, paroi sensiblement parallèle à l'axe longitudinal de la tige 216 et l'extrémité externe du joint secondaire 58.The secondary seal 58 is placed between the main seal 56 and the shoulder 78 of the valve body 218, in leaktight contact with the lower flange 69 of the rod 216 under the action of the spring 54. It comprises at its upper part one or several channels 84 arranged radially relative to the longitudinal axis of the rod 216. A clearance 86 exists between the internal wall 87 of the shoulder 78, a wall substantially parallel to the longitudinal axis of the rod 216 and the external end of the secondary seal 58.

La zone 224 d'extrémité libre du corps de valve 218 forme une zone de raccordement pour un tube plongeur s'étendant jusqu'au fond du réservoir. L'intérieur du corps de valve est donc rempli du produit à distribuer. L'orifice 76 du corps de valve 218 est en contact avec la vapeur du propulseur.The free end zone 224 of the valve body 218 forms a connection zone for a dip tube extending to the bottom of the tank. The interior of the valve body is therefore filled with the product to be dispensed. The orifice 76 of the valve body 218 is in contact with the vapor of the propellant.

Comme visible sur la figure 3, l'extrémité libre de la conduite 64 de la tige 216 débouche contre le joint principal 56 et l'extrémité libre de la conduite 66 débouche contre le joint secondaire 58.As can be seen in FIG. 3, the free end of the pipe 64 of the rod 216 opens out against the main seal 56 and the free end of the pipe 66 opens out against the secondary seal 58.

Pour utiliser le dispositif de la figure 3, comme illustré à la figure 4, on appuie sur la partie supérieure 208a du bouton-poussoir 208 , comme indiqué par la flêche F, ce qui provoque l'enfoncement de la tige de valve 216.To use the device in FIG. 3, as illustrated in FIG. 4, the upper part 208a of the push button 208 is pressed, as indicated by the arrow F, which causes the valve stem 216 to sink.

Lors du déplacement de la tige 216, l'extrémité libre de la conduite 62 se dégage du joint secondaire 58 et se trouve en contact avec le produit contenu dans le corps de valve 218. Le produit, sous la pression du propulseur, est expulsé dans la conduite 66 puis dans le cylindre interne 62 et passe dans le conduit 50 et dans le canal 236b du bouton-poussoir 208 pour être ainsi distribué sous forme de spray large et doux à travers la deuxième buse 228b. Le circuit du produit est symbolisé par les flèches p.
Le déplacement de la tige dégage également l'extrémité libre de la conduite 64 du joint principal 56. Le propulseur, sous forme de gaz, contenu dans le récipient, pénètre dans l'orifice 76 du corps de valve 218 puis dans la rigole 84 du joint secondaire 58 qui débouche à l'extrémité libre de la conduite 64. Le propulseur se dirige donc de la conduite 64 vers le cylindre externe 60 et passe dans le conduit annulaire 52 puis dans le canal 36a pour être ainsi distribué à travers la première buse 228a. Ainsi, la première buse délivre un spray de gaz propulseur ayant un effet mécanique. Le trajet de ce gaz est symbolisé par la flèche g.During the displacement of the rod 216, the free end of the pipe 62 emerges from the secondary seal 58 and is in contact with the product contained in the valve body 218. The product, under the pressure of the propellant, is expelled into the pipe 66 then in the internal cylinder 62 and passes through the pipe 50 and into the channel 236b of the push button 208 so as to be thus distributed in the form of a broad and soft spray through the second nozzle 228b. The product circuit is symbolized by the arrows p .
The displacement of the rod also releases the free end of the pipe 64 from the main seal 56. The propellant, in the form of gas, contained in the container, penetrates into the orifice 76 of the valve body 218 then into the channel 84 of the secondary seal 58 which opens at the free end of the pipe 64. The propellant therefore goes from the pipe 64 to the external cylinder 60 and passes through the annular pipe 52 then in the channel 36a so as to be thus distributed through the first nozzle 228a. Thus, the first nozzle delivers a spray of propellant gas having a mechanical effect. The path of this gas is symbolized by the arrow g.

Pour mieux diriger le produit sur la cible, il est possible de décaler la deuxième buse par rapport à la première, de sorte que la deuxième buse est plus près de l'axe X-X. Le bouton-poussoir présente alors une zone en retrait.To better direct the product on the target, it is possible to offset the second nozzle relative to the first, so that the second nozzle is closer to the X-X axis. The push button then has a recessed area.

La position des deux buses pourrait bien entendue être inversée.The position of the two nozzles could of course be reversed.

Lorsque le distributeur illustré aux figures 3 et 4 est utilisé pour la distribution d'une laque capillaire, le spray à effet mécanique délivré par la première buse 228a créé un creux sur la chevelure qui est fixé de façon simultanée par le spray de produit délivré par la deuxième buse 228b. On obtient ainsi une mise en forme et une tenue naturelles de la chevelure.When the dispenser illustrated in FIGS. 3 and 4 is used for dispensing a hair spray, the spray with mechanical effect delivered by the first nozzle 228a creates a recess on the hair which is fixed simultaneously by the spray of product delivered by the second nozzle 228b. This gives natural shaping and holding of the hair.
