Description

La présente invention concerne une tête de distribution de produit fluide destinée à être montée sur, ou associée à un organe de distribution de produit fluide tel qu'une valve ou une pompe. La tête de distribution est plus particulièrement appropriée à distribuer le produit fluide sous forme de mousse. Une telle tête de distribution peut notamment trouver une application dans les domaines les plus divers, comme celui des produits corporels (mousse à raser), de la pharmacie, des produits alimentaires, etc comme décrit dans les documents JP 2002 36255 , JP 2001 31589 et JP 2001 151 287 . Toutefois, la tête de distribution de la présente invention peut également servir à distribuer d'autres types de produit fluide qui ne sont pas nécessairement moussants.The present invention relates to a fluid dispenser head intended to be mounted on or associated with a fluid dispenser member such as a valve or a pump. The dispensing head is more particularly suitable for dispensing the fluid product in the form of foam. Such a dispensing head may especially find application in the most diverse fields, such as that of body products (shaving foam), pharmacy, food products, etc. as described in the documents JP 2002 36255 , JP 2001 31589 and JP 2001 151 287 . However, the dispensing head of the present invention can also be used to dispense other types of fluid that are not necessarily foaming.

Les têtes de distribution de mousse présentent en général une conception apte à favoriser la formation de la mousse. Pour cela, la tête de distribution doit générer le maximum de turbulences dans le produit fluide. On sait bien que les turbulences favorisent la formation de la mousse en augmentant la qualité du mélange du produit fluide avec un gaz, qui peut être de l'air.Foam dispensing heads generally have a design capable of promoting the formation of foam. For this, the dispensing head must generate the maximum turbulence in the fluid product. It is well known that turbulence promotes the formation of foam by increasing the quality of the mixture of the fluid with a gas, which may be air.

Un but de la présente invention est de définir une tête de distribution qui permet de générer un maximum de turbulences. Un autre but est de réaliser une tête de distribution qui soit facilement moulable. Encore un autre but est de réaliser une tête de distribution avec un minimum de pièces, dont l'assemblage est simple.An object of the present invention is to define a dispensing head which makes it possible to generate a maximum of turbulence. Another goal is to achieve a dispensing head that is easily moldable. Yet another goal is to achieve a dispensing head with a minimum of parts, the assembly is simple.

Pour atteindre ces buts, la présente invention propose une tête de distribution de produit fluide, comme décrit dans les documents JP 2002 36255 , JP 2001 31589 et JP 2001 151 28 Le bouchon permet de réduire efficacement et simplement sa section de l'ouverture axiale en définissant ainsi un orifice de distribution dont la section efficace de passage ne varie pas dans le temps, puisque le bouchon est fixe, contrairement à un clapet.To achieve these goals, the present invention provides a fluid dispenser head, as described in the documents JP 2002 36255 , JP 2001 31589 and JP 2001 151 28 The plug effectively and simply reduces its section of the axial opening thus defining a dispensing orifice whose passage cross section does not change over time, since the cap is fixed, unlike a valve.

Avantageusement, le bouchon comprend un pied en prise dans le canal de sortie et une pastille qui obstrue partiellement l'ouverture du canal de sortie de manière à définir un orifice de distribution annulaire qui s'étend autour de la pastille qui est avantageusement inclinée par rapport à l'axe Y. Avantageusement, la pastille forme une face interne qui s'étend transversalement à l'axe Y et contre laquelle le produit fluide cogne avant d'être distribué à travers l'orifice de distribution. Le bouchon est aisément insérable de manière axiale dans le canal de sortie de la tête. Bien que sa pastille puisse être inclinée, son pied s'étend parfaitement axialement dans le canal de sortie. Le fait que le produit fluide bute contre la face interne de la pastille favorise encore la génération de turbulences.Advantageously, the plug comprises a foot engaged in the outlet channel and a pellet which partially obstructs the opening of the outlet channel so as to define an annular distribution orifice which extends around the pellet which is advantageously inclined relative to Advantageously, the pellet forms an inner face that extends transversely to the Y axis and against which the fluid product knocks before being distributed through the dispensing orifice. The plug is easily axially insertable into the outlet channel of the head. Although its pellet can be inclined, its foot extends perfectly axially in the outlet channel. The fact that the fluid product abuts against the inner face of the pellet further promotes the generation of turbulence.

Selon l'invention , l'axe Y du canal de sortie est distinct de l'axe X, de sorte que le canal de sortie est décalé par rapport au manchon de raccordement. Les axes X et Y peuvent être parallèles, mais décalés.According to the invention, the Y axis of the output channel is distinct from the X axis, so that the output channel is offset with respect to the connecting sleeve. The X and Y axes can be parallel but offset.

Avantageusement, le manchon de raccordement relie le canal de sortie à travers un conduit de liaison qui s'étend selon un troisième axe Z qui est parallèle à l'axe Y, mais décalé par rapport à celui-ci, de sorte que le manchon, le canal, et le conduit s'étendent tous selon des axes distincts X, Y et Z, respectivement. Avec trois sections de passage de produit fluide décalés les uns par rapport aux autres, le produit fluide est contraint de s'écouler à travers un chemin très sinueux ou chicane, ce qui favorise la génération de turbulences. De plus, lorsque le manchon, le canal et le conduit s'étendent tous de manière axiale, la tête de distribution est facilement moulable et démoulable. Un moule constitué uniquement de deux parties de moule est suffisant pour mouler la tête de distribution de l'invention.Advantageously, the connecting sleeve connects the outlet channel through a connecting conduit which extends along a third axis Z which is parallel to the axis Y, but offset with respect thereto, so that the sleeve, the channel, and the duct all extend along distinct axes X, Y and Z, respectively. With three fluid product passage sections staggered relative to each other, the fluid product is forced to flow through a very sinuous path or baffle, which promotes the generation of turbulence. In addition, when the sleeve, the channel and the duct all extend axially, the dispensing head is easily moldable and demoldable. A mold consisting solely of two mold parts is sufficient to mold the dispensing head of the invention.

Selon une autre caractéristique intéressante de l'invention, le manchon forme un logement interne qui est centré sur l'axe X, ce logement étant destiné à recevoir la sortie de l'organe de distribution, ce logement étant prolongé par un sas d'entrée, qui est également centré sur l'axe X, ce sas communiquant avec le conduit de liaison à travers une fenêtre latérale. Ainsi, le produit fluide qui sort de l'organe de distribution cogne contre l'extrémité bouchée ou borgne du sas d'entrée, et est ainsi contraint de s'écouler à travers la fenêtre latérale qui donne dans le conduit de liaison. Avantageusement, le conduit comprend une extrémité inférieure borgne et le sas comprend une extrémité supérieure borgne.According to another advantageous characteristic of the invention, the sleeve forms an internal housing which is centered on the axis X, this housing being intended to receive the outlet of the dispensing member, this housing being extended by an airlock which is also centered on the X axis, this airlock communicating with the connecting conduit through a side window. Thus, the fluid product that comes out the dispensing member knocks against the plugged or blind end of the airlock, and is thus forced to flow through the side window that gives into the connecting pipe. Advantageously, the conduit comprises a blind lower end and the lock comprises a blind upper end.

Selon un autre aspect de l'invention, le conduit comprend une extrémité supérieure ouverte qui débouche axialement dans le canal de sortie. Ainsi, il est possible de mouler le conduit de liaison avec une broche qui s'étend à travers le canal de sortie. Avantageusement, l'axe Z traverse le canal de sortie sur toute sa longueur axiale.According to another aspect of the invention, the conduit comprises an open upper end which opens axially into the outlet channel. Thus, it is possible to mold the connecting conduit with a pin that extends through the output channel. Advantageously, the Z axis passes through the outlet channel over its entire axial length.

Selon un autre aspect intéressant de l'invention, la tête de distribution comprend une bague pourvue de moyens de fixation pour la fixation de la bague sur un réservoir de produit fluide, et un poussoir formant une surface d'appui sur laquelle on peut appuyer pour déplacer le poussoir par rapport à la bague, le poussoir formant également le manchon de raccordement et un embout saillant qui définit intérieurement le conduit de liaison et le canal de sortie, cet embout étant coiffé par le bouchon. Avantageusement, le poussoir comprend une couronne périphérique qui est reliée à la bague par au moins un pont de matière, la bague formant une collerette saillante qui entoure la couronne de manière concentrique, de sorte que l'extrémité inférieure de la couronne est située axialement en-dessous du bord supérieur de la collerette. La collerette saillante masque ainsi une partie de la couronne : cela permet de se passer d'un positionnement précis du poussoir dans la bague.According to another advantageous aspect of the invention, the dispensing head comprises a ring provided with fastening means for fixing the ring to a fluid reservoir, and a pusher forming a bearing surface on which it is possible to press for move the pusher relative to the ring, the pusher also forming the connecting sleeve and a projecting tip which defines internally the connecting conduit and the outlet channel, this end being capped by the cap. Advantageously, the pusher comprises a peripheral ring which is connected to the ring by at least one bridge of material, the ring forming a protruding collar which surrounds the ring concentrically, so that the lower end of the ring is situated axially in position. below the top edge of the collar. The protruding collar thus masks a portion of the crown: this makes it possible to dispense with precise positioning of the pusher in the ring.

Les axes X, Y et Z sont des axes de symétrie, qui passent longitudinalement au centre du manchon, du canal, et du conduit, respectivement. Le manchon, le sas, le conduit et le canal, présentent une forme généralement ou sensiblement cylindrique et les axes X, Y et Z constituent des axes de génératrices de cylindres. Même dans le cas où le manchon, le sas, le conduit et/ou le canal ne présentent pas une configuration sensiblement ou principalement cylindrique, on peut toujours définir un axe longitudinal de plus grande symétrie. Les axes X, Y et Z peuvent également être entendus dans ce sens.The X, Y and Z axes are axes of symmetry, which pass longitudinally in the center of the sleeve, channel, and duct, respectively. The sleeve, the airlock, the duct and the channel have a generally or substantially cylindrical shape and the X, Y and Z axes constitute cylinders generating axes. Even in the case where the sleeve, the airlock, the duct and / or the channel do not have a substantially or mainly cylindrical configuration, it is always possible to define a longitudinal axis of greater symmetry. The X, Y and Z axes can also be heard in this direction.

Le bouchon, ainsi que le décalage entre le manchon, le canal et le conduit, contribuent à générer des turbulences dans le produit fluide avant sa distribution, ce qui est particulièrement avantageux pour les distributeurs de mousse.The plug, as well as the offset between the sleeve, the channel and the duct, contribute to generate turbulence in the fluid before distribution, which is particularly advantageous for foam dispensers.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example an embodiment of the invention.

In the figures:

La tête de distribution utilisée pour illustrer la présente invention est représentée sur les figures 1 et 2 comprend trois éléments constitutifs, à savoir une bague de fixation 1, un poussoir distributeur 2 et un bouchon 3. La bague 1 et le poussoir 2 peuvent être réalisés de manière monobloc, de sorte qu'ils ne forment qu'une seule pièce. Ils peuvent donc être moulés dans un seul et même moule. La bague 1, le poussoir 2, ainsi que le bouchon 3 peuvent être réalisés par injection-moulage de matière plastique appropriée. La bague 1 et le poussoir 2 peuvent être réalisés avec des matériaux plastiques différents ou avec une même matière plastique de couleurs différentes. Il en est de même pour le bouchon 3 qui peut être réalisé en un matériau plastique différent ou de couleur différente de celui de la bague 1 et du poussoir 2.The dispensing head used to illustrate the present invention is shown on the Figures 1 and 2 comprises three constituent elements, namely a fixing ring 1, a dispensing pusher 2 and a plug 3. The ring 1 and the pusher 2 can be made in one piece, so that they form a single piece. They can therefore be molded in one and the same mold. The ring 1, the pusher 2 and the cap 3 can be made by injection-molding of suitable plastic material. The ring 1 and the pusher 2 can be made with different plastic materials or with the same plastic of different colors. It is the same for the cap 3 which can be made of a different plastic material or different color from that of the ring 1 and the pusher 2.

La bague de fixation 1 a une forme très généralement cylindrique et présente ainsi une symétrie de révolution par rapport à un axe central X. La bague qui définit dans sa partie inférieure une jupe de fixation 11, et dans sa partie supérieure, une collerette saillante 12. La jupe de fixation 11 définit des moyens de fixation, par exemple sous la forme d'un logement d'encliquetage interne, dans lequel peut venir se loger la partie supérieure d'un réservoir. On peut bien entendu envisager des jupes de fixation différentes, utilisant des techniques de fixation différentes, comme par exemple le vissage, le collage ou le sertissage. De manière tout à fait générale, la bague de fixation 1 sert à la fixation de la tête de distribution sur un élément fixe du distributeur, c'est-à-dire un élément qui est solidaire directement ou indirectement du réservoir de produit fluide ou d'une partie fixe d'un organe de distribution, tel qu'une pompe ou une valve. Par conséquent, la bague de fixation 1 peut également être adaptée à venir en prise avec une partie fixe d'un organe de distribution, tel qu'une pompe ou une valve. On peut même imaginer que la bague de fixation 1 soit réalisée de manière monobloc avec une partie du réservoir et/ou de l'organe de distribution.The fixing ring 1 has a very generally cylindrical shape and thus has a symmetry of revolution with respect to a central axis X. The ring which defines in its lower part a fixing skirt 11, and in its upper part, a projecting flange 12 The fixing skirt 11 defines fastening means, for example in the form of an internal snap-fitting housing, into which the upper part of a tank can be housed. One can of course consider different fixing skirts, using different fastening techniques, such as screwing, gluing or crimping. In a very general manner, the fixing ring 1 is used for fixing the dispensing head on a fixed element of the dispenser, that is to say an element which is integral directly or indirectly with the fluid reservoir or d a fixed part of a dispensing member, such as a pump or a valve. Therefore, the fixing ring 1 can also be adapted to engage a fixed part of a dispensing member, such as a pump or a valve. One can even imagine that the fixing ring 1 is made integrally with a portion of the reservoir and / or the dispenser member.

Le poussoir distributeur 2 comprend une couronne 21 qui définit le diamètre maximal du poussoir 2. La couronne 21 présente une symétrie de révolution autour d'un axe qui est confondu avec l'axe X qui est l'axe de symétrie de la bague. La couronne 21 est engagée à l'intérieur de la collerette saillante 12 de la bague 1, et est reliée, au niveau de son extrémité inférieure, à la paroi interne de la collerette 12, par au moins un pont de matière 22. En pratique, il y a plusieurs ponts de matière, en général deux, qui ont des fonctions différentes. Un pont de matière résistant sert de charnière ou d'articulation, alors que l'autre pont de matière est cassant et sert de sécurité de premier usage. En général, ces deux ponts de matière peuvent être disposés de manière diamétralement opposée. Sur les figures, on voit un pont de matière 22 situé sur la partie gauche de la tête. Ce pont de matière peut par exemple s'étendre sur une petite partie de la périphérie de la couronne 21, et servir de charnière ou d'articulation. Sur le côté droit, on aurait pu représenter un autre pont de matière cassant, qui sert de sécurité de premier usage. Il est bien entendu possible de prévoir plusieurs ponts de matière pour réaliser la fonction de charnière et plusieurs ponts de matière pour réaliser la fonction de sécurité de premier usage. Il est également possible de ne prévoir qu'un (ou plusieurs) pont(s) de matière servant d'articulation ou de charnière et de se passer ainsi de pont de matière cassant servant de sécurité de premier usage. En tout cas, on peut remarquer que la couronne 21 pénètre à l'intérieur de la collerette saillante 22, de sorte que son extrémité inférieure est située axialement bien en dessous de l'extrémité supérieure libre de la collerette 12. Ainsi, il n'est pas absolument nécessaire que la couronne 21 soit positionnée avec une précision extrême à l'intérieur de la collerette 12. Le bord inférieur de la couronne 21, qui sert de référence visuelle pour l'assiette du poussoir 2 par rapport à la bague 1, n'est en effet pas visible, puisque masqué par la collerette 12.The distributor pusher 2 comprises a ring 21 which defines the maximum diameter of the pusher 2. The ring 21 has a symmetry of revolution about an axis which is coincident with the axis X which is the axis of symmetry of the ring. The ring 21 is engaged inside the projecting collar 12 of the ring 1, and is connected, at its lower end, to the inner wall of the collar 12, by at least one bridge of material 22. In practice there are several bridges of matter, usually two, which have different functions. A bridge of resistant material serves as a hinge or articulation, while the other material bridge is brittle and serves as a first-use security. In general, these two material bridges can be arranged diametrically opposite. In the figures, there is a material bridge 22 located on the left side of the head. This bridge material can for example extend over a small portion of the periphery of the ring 21, and serve as hinge or articulation. On the right side, we could have represented another bridge of brittle material, which serves as security of first use. It is of course possible to provide several bridges of material to perform the hinge function and several material bridges to achieve the first-use safety function. It is also possible to provide only one (or more) bridge (s) of material serving as hinge or hinge and to do without bridge brittle material serving as a first-use security. In any case, it may be noted that the ring 21 penetrates inside the projecting flange 22, so that its lower end is located axially well below the free upper end of the flange 12. Thus, it does not is not absolutely necessary that the ring 21 is positioned with extreme precision inside the collar 12. The lower edge of the ring 21, which serves as a visual reference for the plate of the pusher 2 relative to the ring 1, is indeed not visible, since masked by the collar 12.

Au-delà de la couronne 21, le poussoir distributeur 2 présente une configuration complètement asymétrique et excentrée. Le poussoir définit une surface d'appui 23, qui est disposée sur la partie droite de la tête lorsque l'on regarde les figures 1 et 2, et un embout saillant 28 qui est désaxé sur la partie gauche de la tête lorsque l'on regarde les figures 1 et 2. La surface d'appui 23 sert à l'apposition d'un ou de plusieurs doigts de la main de l'utilisateur, afin d'exercer une poussée sensiblement axiale vers le bas pour déplacer le poussoir distributeur 2 par rapport à la bague 1. Le déplacement du poussoir 2 par rapport à la bague 1 s'effectue ici par un basculement du poussoir 2 vers la droite lorsque l'on regarde les figures, étant donné que le poussoir 2 est relié à la bague 1 par le pont de matière 22 formant charnière et situé sur la partie gauche de la tête en regardant les figures 1 et 2. Le décentrage de l'embout 28 par rapport à la couronne 21 et la bague 1 permet de dégager une plus grande surface d'appui 23. L'embout 28 fait saillie axialement vers le haut, à partir de la couronne 21, et à partir de la surface d'appui 23. L'embout 28 comprend une paroi sensiblement verticale, qui s'étend dans l'axe X et une paroi opposée totalement excentrée qui forme une pente exponentielle. A son extrémité supérieure, l'embout 28 forme une ouverture 29 qui est disposée de manière inclinée.Beyond the ring 21, the distributor pusher 2 has a completely asymmetrical and eccentric configuration. The pusher defines a bearing surface 23, which is arranged on the right part of the head when one looks at them. Figures 1 and 2 , and a projecting tip 28 which is off-center on the left part of the head when we look at them. Figures 1 and 2 . The bearing surface 23 serves to affix one or more fingers of the hand of the user, in order to exert a substantially axial thrust downwards to move the dispensing plunger 2 relative to the ring 1. The displacement of the pusher 2 relative to the ring 1 is effected here by a tilting of the pusher 2 to the right when one looks at the figures, since the pusher 2 is connected to the ring 1 by the material bridge 22. hinge and located on the left side of the head looking at the Figures 1 and 2 . The off-centering of the end piece 28 with respect to the ring 21 and the ring 1 makes it possible to disengage a larger bearing surface 23. The end piece 28 projects axially upwards, starting from the ring 21, and from of the bearing surface 23. The tip 28 comprises a substantially vertical wall, which extends in the X axis and a totally offset side wall which forms an exponential slope. At its upper end, the tip 28 forms an opening 29 which is inclined.

Le poussoir distributeur 2 forme intérieurement un manchon de raccordements 24 qui définit un logement de réception 241 pour une sortie de produit fluide 4 faisant partie d'un organe de distribution tel qu'une pompe ou une valve. En pratique, cette sortie de distribution 4 est constituée par l'extrémité supérieure de la tige d'actionnement d'une pompe ou de la tige de soupape d'une valve. Le manchon de raccordement 24 forme également un sas d'entrée 25 qui s'étend dans le prolongement du logement de réception 241. Le logement 241, ainsi que le sas d'entrée 25 s'étendent de manière centrée par rapport à l'axe X.The dispensing plunger 2 internally forms a connection sleeve 24 which defines a receiving housing 241 for a fluid outlet 4 forming part of a dispensing member such as a pump or a valve. In practice, this dispensing outlet 4 is constituted by the upper end of the actuating rod of a pump or the valve stem of a valve. The connecting sleeve 24 also forms an inlet lock chamber 25 which extends in the extension of the receiving housing 241. The housing 241, as well as the inlet lock chamber 25 extend centrally with respect to the axis X.

D'autre part, le poussoir distributeur 2 forme un conduit de liaison 26 qui s'étend de manière centrée par rapport à un autre axe Z qui est incliné ou parallèle à l'axe X, mais qui est décalé par rapport à celui-ci. Sur les figures, les axes X et Z sont parallèles. Le conduit de liaison 26 présente une configuration sensiblement cylindrique, et l'axe Z constitue la génératrice du cylindre. Le conduit de liaison 26 présente une extrémité inférieure fermée ou borgne, et une extrémité supérieure ouverte. Le conduit de liaison 26 communique avec le sas 25 à travers une fenêtre latérale 256. L'extrémité supérieure du sas d'entrée 25 est fermée ou borgne. Ainsi, le sas d'entrée 25 et le conduit de liaison 26 sont décalés axialement l'un par rapport à l'autre : le produit fluide issu de la sortie 4 est ainsi projeté contre la paroi supérieure borgne du sas d'entrée 25, ce qui contraint le produit fluide à s'écouler à travers la fenêtre 256 et cogner contre la paroi du conduit de liaison 26, pour ensuite être réorienté vers le haut, étant donné que l'extrémité inférieure du conduit 26 est borgne. Ce passage tortueux forme un chemin d'écoulement de produit fluide, qui favorise les turbulences et ainsi améliore la qualité de la mousse.On the other hand, the distributor pusher 2 forms a connecting pipe 26 which extends centrally with respect to another axis Z which is inclined or parallel to the axis X, but which is offset with respect thereto. . In the figures, the X and Z axes are parallel. The connecting pipe 26 has a substantially cylindrical configuration, and the Z axis is the generatrix of the cylinder. The connecting conduit 26 has a closed or blind lower end, and an open upper end. The connecting conduit 26 communicates with the lock 25 through a side window 256. The upper end of the entry lock 25 is closed or blind. Thus, the entry lock 25 and the connecting conduit 26 are offset axially with respect to each other: the fluid product from the outlet 4 is thus projected against the blind upper wall of the entry lock chamber 25, this forces the fluid to flow through the window 256 and bump against the wall of the connecting pipe 26, then to be reoriented upwards, since the lower end of the conduit 26 is blind. This tortuous passage forms a flow path of fluid product, which promotes turbulence and thus improves the quality of the foam.

Le poussoir distributeur 2 forme également un canal de sortie 27, qui s'étend de manière centrée par rapport à un autre axe Y, qui est parallèle à l'axe Z, mais qui est décalé par rapport à celui-ci. Sur les figures, les trois axes X, Y et Z sont parallèles, mais il est également envisageable que les axes Y et Z soient parallèles, mais inclinés par rapport à l'axe X. Le canal de sortie 27 présente une configuration sensiblement cylindrique avec l'axe Y formant la génératrice du cylindre. On dispose ainsi de trois sections de passage qui sont décalées les unes par rapport aux autres. Le conduit de liaison 26 communique directement dans le canal de sortie 27. On peut même remarquer que l'axe de symétrie Z du conduit 26 traverse le canal de sortie 27 sur toute sa longueur. Plus précisément, la paroi de droite du conduit 26 et du canal 27 sont toutes deux formées par la paroi verticale centrale axiale de l'embout 28. En revanche, la paroi de gauche du canal 27 est excentrée vers la gauche par rapport à la paroi gauche du conduit 26. De ce fait, la section transversale du canal 27 est supérieure à la section transversale du conduit 26. L'extrémité supérieure du canal de sortie 27 est formée par l'ouverture 29 de l'embout 28. Cette ouverture 29 s'étend de manière inclinée par rapport à l'axe Y, sans pour autant être perpendiculaire à l'axe Y. L'ouverture 29 fait un angle d'environ 45° par rapport à l'axe Y. L'ouverture 29 peut également être perpendiculaire à l'axe Y.The dispensing plunger 2 also forms an outlet channel 27, which extends centrally with respect to another Y axis, which is parallel to the Z axis, but which is offset with respect thereto. In the figures, the three axes X, Y and Z are parallel, but it is also conceivable that the Y and Z axes are parallel, but inclined with respect to the axis X. The outlet channel 27 has a substantially cylindrical configuration with the Y axis forming the generator of the cylinder. There are thus three passage sections that are offset relative to each other. The connecting duct 26 communicates directly in the outlet channel 27. It may even be noted that the axis of symmetry Z of the duct 26 passes through the outlet channel 27 over its entire length. Specifically, the right wall of the duct 26 and the channel 27 are both formed by the axial central vertical wall of the nozzle 28. In contrast, the left wall of the channel 27 is eccentric to the left relative to the wall Thus, the cross section of the channel 27 is greater than the cross section of the conduit 26. The upper end of the outlet channel 27 is formed by the opening 29 of the nozzle 28. This opening 29 extends inclined relative to the axis Y, without being perpendicular to the axis Y. The opening 29 makes an angle of about 45 ° with respect to the Y axis. The opening 29 may also be perpendicular to the Y axis.

L'embout 28 définit ainsi un passage de fluide très sinueux formé avec trois secteurs de passage distincts, qui s'étendent le long d'axes parallèles décalés distincts. Ceci favorise grandement la génération de turbulence, qui est propice à la formation d'une mousse de bonne qualité.The tip 28 thus defines a very sinuous fluid passage formed with three distinct passage sectors, which extend along distinct offset parallel axes. This greatly favors the generation of turbulence, which is conducive to the formation of a good quality foam.

Le bouchon 3 est rapporté dans le canal 27 et fixé en place. Pour ce faire, le bouchon 3 comprend un pied de fixation 31 et une pastille d'obturation 34. Le pied 31 est destiné à être inséré en force à l'intérieur du canal de sortie 27. Le bouchon est ainsi monté fixement dans le canal. Le pied 31 forme plusieurs nervures verticales radiales 32 qui s'étendent tout autour du pied. Ces nervures 32 sont destinées à venir en prise serrante avec la paroi interne du canal de sortie 27. Pour favoriser l'accrochage de ces nervures 32 à l'intérieur du canal 27, il est prévu une ou plusieurs nervures d'accrochage 33 qui viennent mordre dans la paroi interne du canal 27. On peut avantageusement utiliser un matériau plus dur pour le bouchon 3 que pour le poussoir 2. Une fois en prise à l'intérieur du canal 27, comme on peut le voir sur la figure 2, les nervures radiales verticales 32 définissent entre elles plusieurs passages de produit fluide qui permettent d'atteindre la pastille 34. La section transversale horizontale du pied 31 du bouchon 3 peut par exemple présenter une forme d'étoile à plusieurs branches formées par les nervures 32. La pastille d'obturation 34 connecte le pied 31 en formant un angle d'environ 45°. La pastille 34 comprend une face interne inférieure 341 et une face externe supérieure 342. Les nervures 32 sont reliées au niveau de leurs extrémités supérieures à la face inférieure 341. Une fois en place dans le canal de sortie 27, le pied 31 est entièrement reçu à l'intérieur du canal 27, alors que la pastille 34 est parfaitement logée à l'intérieur du bord formé par l'ouverture 29. Il subsiste cependant un interstice entre la pastille 34 et le bord de l'ouverture 29, qui constitue un orifice de distribution périphérique annulaire 35. Cet orifice de distribution 35 est en communication directe avec les passages formés entre les nervures 32. La pastille 34 est pratiquement entièrement logée à l'intérieur du bord formé par l'ouverture 29. Du fait que le bouchon est monté fixement dans le canal 27, la section de l'orifice de distribution est constante, bien qu'elle puisse ne pas être uniforme.The plug 3 is attached in the channel 27 and fixed in place. To do this, the cap 3 comprises a fixing foot 31 and a sealing pad 34. The foot 31 is intended to be inserted into force inside the outlet channel 27. The cap is thus fixedly mounted in the channel . The foot 31 forms a plurality of vertical radial ribs 32 which extend all around the foot. These ribs 32 are intended to engage tightly with the inner wall of the outlet channel 27. To promote the attachment of these ribs 32 within the channel 27, there is provided one or more attachment ribs 33 which come bite in the inner wall of the channel 27. It is advantageous to use a harder material for the plug 3 than for the pusher 2. Once engaged inside the channel 27, as can be seen on the figure 2 , the vertical radial ribs 32 define between them several passages of fluid product which make it possible to reach the pellet 34. The horizontal cross section of the foot 31 of the cap 3 may for example have a star shape with several branches formed by the ribs 32 The shutter pad 34 connects the foot 31 at an angle of about 45 °. The pellet 34 comprises a lower inner face 341 and an upper outer face 342. The ribs 32 are connected at their upper ends to the lower face 341. Once in place in the outlet channel 27, the foot 31 is entirely received inside the channel 27, while the pellet 34 is perfectly housed inside the edge formed by the opening 29. There remains however a gap between the pellet 34 and the edge of the opening 29, which constitutes a annular peripheral dispensing orifice 35. This dispensing orifice 35 is in direct communication with the passages formed between the ribs 32. The pellet 34 is substantially completely housed inside the edge formed by the opening 29. Because the plug is fixedly mounted in the channel 27, the section of the dispensing orifice is constant, although it may not be uniform.

Les nervures 32 du pied 31, en subdivisant le canal de sortie 27 en plusieurs passages axiaux contribuent également à la génération de turbulences. Il en est de même pour la face interne inférieure 341 de la pastille 34 contre laquelle le produit fluide est contraint de venir cogner après s'être écoulé à travers les passages radiaux formés par les nervures 32. Ensuite, le produit fluide déjà fortement moussé est contraint de s'échapper à travers l'orifice de distribution qui n'est formé que par un interstice relativement faible.The ribs 32 of the foot 31, by dividing the outlet channel 27 into several axial passages also contribute to the generation of turbulence. It is the same for the lower inner face 341 of the pellet 34 against which the fluid is forced to come knock after having passed through the radial passages formed by the ribs 32. Then, the fluid already heavily foamed is forced to escape through the dispensing orifice which is formed only by a relatively small gap.

Ainsi, lorsqu'un utilisateur appuie sur la surface 23, le poussoir 2 bascule hors de son axe par pivotement au niveau du pont de matière 22 qui sert d'articulation ou de charnière. Ce basculement a pour effet de déplacer la sortie 4 de l'organe de distribution et ainsi de déclencher la distribution du produit fluide qui est initialement stocké dans un réservoir, et alimenté par l'organe de distribution. Le produit fluide parvient dans le sas 25 où il cogne l'extrémité supérieure borgne, ce qui l'oblige à s'écouler à travers la fenêtre 256 puis à travers le conduit de liaison 26. De là, le produit fluide peut s'écouler vers le haut directement dans le canal de sortie 27. Le produit fluide est alors contraint de se diviser pour s'écouler à travers la pluralité de passages axiaux formée par les nervures 32 du pied 31 du bouchon 3. Le produit fluide parvient ensuite jusqu'à la face inférieure 341 de la pastille 34 où il est contraint de s'échapper à travers l'orifice de distribution 35. Grâce à ce chemin d'écoulement particulièrement sinueux, le produit fluide subit beaucoup de turbulences, ce qui a pour effet d'augmenter la qualité de la mousse.Thus, when a user presses the surface 23, the pusher 2 pivots off its axis by pivoting at the material bridge 22 which serves as hinge or hinge. This tilting has the effect of moving the outlet 4 of the dispensing member and thus triggering the dispensing of the fluid product which is initially stored in a reservoir, and fed by the dispensing member. The fluid arrives in the airlock 25 where it knocks the upper blind end, forcing it to flow through the window 256 and through the connecting conduit 26. From there, the fluid can flow upwardly directly in the outlet channel 27. The fluid product is then forced to divide to flow through the plurality of axial passages formed by the ribs 32 of the foot 31 of the cap 3. The fluid product then reaches up to at the lower face 341 of the pellet 34 where it is forced to escape through the dispensing orifice 35. Thanks to this particularly sinuous flow path, the fluid product undergoes a lot of turbulence, which has the effect of 'increase the quality of the foam.
