Description

Distributeur de produit fluide Fluid dispenser
La présente invention concerne un organe de distribution de produit fluide comprenant les composants suivants : un corps destiné à. être associé à un récipient, une tête de distribution montée mobile en translation axiale par rapport au corps, ladite tête étant déplaçable par rapport au corps sur une course d'actionnement, ladite tête comportant un poussoir comprenant une paroi d'appui définissant une surface externe d'appui et une surface interne et une jupe latérale s'étendant à partir de ladite paroi d'appui, ladite jupe latérale comportant une surface externe et une surface interne, une chambre définie entre ledit corps et ladite tête, ladite chambre étant pourvue d'au moins un clapet d'entrée et/ou de sortie, un orifice de distribution par lequel du produit fluide est distribué. La présente invention concerne également un distributeur de produit fluide incorporant un tel organe de distribution pouvant notamment être utilisé dans les secteurs de la pharmacie ou de la cosmétique. De nombreux systèmes de distribution de produit fluide, notamment qui intègrent une pompe comme organe de distribution, existent à. l'heure actuelle. Ces systèmes peuvent présenter des caractéristiques structurelles et fonctionnelles plus ou moins distinctes donnant ainsi lieu à des dispositifs plus ou moins simples à assembler et plus ou moins coûteux. Les distributeurs de produit fluide comportent un récipient, un organe de distribution, tel qu'une pompe ou une valve, monté sur ledit récipient, et un poussoir permettant d'actionner ledit organe de distribution afin de distribuer un volume de produit fluide contenu dans le récipient à travers un orifice de distribution. En outre, la plupart des dispositifs renferment une chambre comportant un clapet d'entrée et/ou un clapet de sortie isolant le produit fluide contenu dans le récipient de l'extérieur. Le document WO 02/096776 divulgue par exemple un mode de réalisation d'un dispositif de distribution dans lequel un embout médian est intégré à un poussoir afin de servir d'organe mobile de clapet d'entrée. Dans ce cas, l'actionnement du poussoir entraîne tout d'abord un contact avec un piston qui est alors déplacé en translation axiale. Ce déplacement engendre alors simultanément une fermeture du clapet d'entrée et une ouverture du clapet de sortie. La descente du piston est alors à l'origine d'une réduction de volume de la chambre de pompe ayant pour effet d'expulser le produit fluide contenu dans ladite chambre. Ensuite, le poussoir est rappelé vers sa position initiale de repos. Le poussoir se désolidarise du piston qui reste momentanément immobile. Le déplacement relatif entre le piston et le poussoir engendre l'ouverture du clapet d'entrée, afin de mettre la chambre en communication avec le récipient, et la fermeture simultanée du clapet de sortie pour isoler la chambre de l'extérieur. Ainsi, le piston demeure immobile jusqu'à ce qu'un épaulement du poussoir vienne en butée contre un épaulement correspondant du piston. Le piston est alors entraîné en translation et remonte vers sa position initiale provoquant alors une dépression dans la chambre à l'origine de l'aspiration du produit fluide contenu dans le récipient. Ainsi, il s'avère que ce mode de réalisation tel que décrit n'intègre pas de précompression, l'ouverture et la fermeture du clapet d'entrée et du clapet de sortie se faisant simultanément indépendamment de toute élévation de pression dans la chambre de pompe. En outre, selon cette invention, les mouvements du piston et de l'embout médian ne sont synchrones que sur une courte distance de la course d'actionnement du poussoir, ces deux éléments nécessitant d'évoluer à des vitesses de translation axiale distinctes pour que la pompe ά-décrite fonctionne correctement. Par conséquent, le dispositif de distribution faisant l'objet de ce brevet présente un principe de fonctionnement complexe entraînant ainsi une difficulté d'assemblage et de fabrication dudit dispositif ainsi qu'un coût de revient sensiblement élevé. La présente invention a pour but de fournir un organe de distribution et un distributeur de produit fluide incorporant un tel organe de distribution qui ne reproduit pas les inconvénients précités. En particulier, la présente invention a pour but de fournir un organe de distribution tel qu'une pompe à précompression empêchant tout risque de contamination du produit et assurant d'une part une bonne étanchéité et d'autre part une bonne reproductibilité des doses distribuées à chaque actionnement. La présente invention a encore pour but de fournir un organe de distribution et un distributeur incorporant un tel organe de distribution simple à fabriquer, à assembler et de coût relativement faible. La présente invention se propose de résoudre les problèmes susmentionnés en mettant au point un organe de distribution de produit fluide comprenant les composants suivants : - un corps destiné à être associé à un récipient, -une tête de distribution montée mobile en translation axiale par rapport au corps, ladite tête étant déplaçable par rapport au corps sur une course d'actionnement, ladite tête comportant un poussoir comprenant une paroi d'appui définissant une surface externe d'appui et une surface interne et une jupe latérale s'étendant à partir de ladite paroi d'appui, ladite jupe latérale comportant une surface externe et une surface interne, - une chambre définie entre ledit corps et ladite tête, ladite chambre étant pourvue d'au moins un clapet d'entrée et/ou de sortie, - un orifice de distribution par lequel du produit fluide est distribué, caractérisé en ce que ledit poussoir est pourvu d'une tige axiale, ladite tige aa ale formant ledit au moins un clapet d'entrée et/ou de sortie .en coopération avec au moins un des composants, et en ce que ladite tête de distribution comprend un insert associé de manière solidaire au poussoir. Avantageusement, ledit insert et ladite tige axiale sont solidaires dans leur déplacement sur l'ensemble de la course d'actionnement de ladite tête de distribution. Avantageusement, ladite tige axiale comporte un siège de clapet de sortie apte à coopérer avec ledit insert, ledit insert comportant un organe mobile de clapet de sortie. Avantageusement, ledit siège de clapet de sortie comprend une surface cylindrique apte à coopérer avec une lèvre annulaire de l'organe mobile de clapet de sortie pour mettre en communication ladite chambre avec un espace d'expulsion qui s'étend avantageusement autour de ladite tige axiale. Avantageusement, ledit insert comporte un canal de sortie reliant ledit espace d'expulsion à l'orifice de distribution. Avantageusement, l'insert comporte une couronne en prise avec ladite surface interne de la jupe latérale, une bride radiale en prise avec ladite surface interne de la paroi d'appui et une manchette, ladite manchette comportant une lèvre de piston en contact de coulissement étanche avec ledit corps. Avantageusement, l'insert est une pièce unique déformable. Avantageusement, ladite tige axiale comporte un organe mobile de clapet d'entrée apte à coopérer avec un siège de clapet d'entrée formé par ledit corps. Avantageusement, ledit organe mobile de clapet d'entrée comprend au moins une rainure longitudinale apte à coopérer avec un bourrelet annulaire du siège de clapet d'entrée pour mettre en communication ledit récipient avec ladite chambre. Avantageusement, ladite jupe latérale comporte ledit orifice de distribution. Avantageusement, la couronne de l'insert comporte un système de tourbillonnement, ledit système de tourbillonnement se situant en vis-à-vis de l'orifice de distribution. En variante, la surface interne de la jupe latérale comporte un système de tourbillonnement en vis-à-vis de l'orifice de distribution, ledit système de tourbillonnement étant réalisé de manière monobloc dans ladite jupe latérale. Il s'agit là d'une caractéristique qui peut être mise en œuvre indépendamment du fait que le poussoir forme une tige axiale de clapet. Le système de tourbillonnement est ici complété par l'insert qui est reçu fixement dans le poussoir. La présente invention concerne également un distributeur de produit fluide comprenant un récipient et un organe de distribution de produit fluide selon l'invention. En particulier, l'organe de distribution peut tout à fait être adapté à des distributeurs miniatures tels qu'utilisés pour les échantillons. Ainsi, la tige axiale, qui est de préférence réalisée de manière monobloc par le poussoir, a une fonction de siège et/ou d'organe mobile de clapet d'entrée ou de sortie. L'insert engagé fixement dans le poussoir est réalisé de manière séparée pour des raisons de techniques de moulage. Toutefois, il n'est pas exclu que l'insert puisse être réalisé de manière monobloc par le poussoir, de sorte que la tête de distribution serait alors formée d'une seule pièce. D'autre caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante de plusieurs exemples de réalisation de la présente invention donnés à titre d'exemples non limitatifs en regard des dessins joints, et sur lesquels : la figure 1 est une vue schématique globale en section transversale d'un distributeur de produit fluide incorporant un organe de distribution selon l'invention, la figure 2 est une vue agrandie du distributeur de la figure 1 et en particulier de l'organe de distribution de la présente invention, la figure 3 est vue agrandie d'une variante de réalisation du distributeur selon l'invention, et la figure 4 est une vue agrandie d'une autre variante de réalisation du distributeur selon l'invention. En référence aux figures, un distributeur de produit fluideaselon la présente invention comporte deux éléments constitutifs, à savoir un organe de distribution 1 et un récipient 8. Le récipient 8 comporte une ouverture 80 faisant communiquer l'intérieur dudit récipient 8 avec l'extérieur, un col 83, une paroi latérale 81 s'étendant à partir du col 83 et un fond 82.

Le corps 2 présente une symétrique de révolution axiale et est apte à venir s'emmancher sur le col du récipient 8. Le corps 2 comprend un plateau radial 20 à partir duquel s'étend une paroi périphérique 21, un f t 22 et un manchon 23. La paroi périphérique 21 s'étend vers le haut et vers le bas à partir du plateau radial 20. La paroi périphérique 21 présente une surface externe 210 et une surface interne 211. La partie basse de la paroi 21 est avantageusement emmanchée sur le col du récipient 2 de telle sorte que le plateau radial 22 vienne reposer sur le col du récipient et que la surface interne 211 vienne en prise avec la surface externe 810 du récipient 8. Avantageusement, il résulte de cet emmanchement que la surface externe 210 de la paroi périphérique 21 du corps 2 se place dans la continuité de la surface externe 810 du récipient 8 afin de donner au distributeur une forme générale régulière avantageusement cylindrique. La paroi périphérique 21 peut également comporter au niveau de sa surface interne 211 une saillie interne 2100 destinée à servir de butée haute pour la tête de distribution 3. Le fût 22 définit une surface de coulissement étanche pour une manchette 55 formant un élément de piston. s Le manchon 23 forme un siège de clapet d'entrée 230 apte à coopérer avec un organe mobile de clapet d'entrée 70. Le siège de clapet 230 présente avantageusement la forme d'un bourrelet annulaire. Le manchon 23 se prolonge avantageusement vers le bas dans le récipient de teïïe manière à former un tube plongeur 231 comportant un passage 232 par lequel du produit fluide peut transiter. Le corps 2 tel que décrit est avantageusement réalisé monobloc afin de faciliter l'assemblage de l'organe de distribution. Le corps 2 peut être réalisé en tous matériaux appropriés : métal, plastique, ou autres. La tête de distribution 3 comprend avantageusement deux éléments constitutifs, à savoir un poussoir 4 et un insert 5. La tête de distribution 3 est montée mobile sur le corps 2 de telle sorte à pouvoir se déplacer axialement par rapport au corps 2 sur une course d'actionnement A. Le poussoir 4 comporte une paroi d'appui 40 définissant une surface interne 401 et une surface externe d'appui 400 et une jupe latérale 41 s'étendant vers le bas à partir de ladite paroi d'appui 40. La jupe latérale 41 comporte une surface externe 410 et une surface interne 411. La surface externe 410 présente avantageusement un épaulement externe 4100 destiné à coopérer avec la saillie interne 2100 de la paroi périphérique 21 du corps 2 pour former une butée haute. Ainsi, cette butée permet de définir la position de repos de l'organe de distribution 1 et garantit une fonction d'anti-arrachement de la tête de distribution. Il est à remarquer que dans le mode de réalisation tel que représenté, une partie de la surface interne 211 située entre la saillie interne 2100 et le plateau radial 22, sert de paroi de guidage pour le poussoir 4 garantissant ainsi une meilleure orientation axiale du poussoir lors de son déplacement. Un orifice de distribution 42 est avantageusement prévu au niveau de la jupe latérale 41. L'orifice de distribution 42 peut alors être situé au bout d'un canal dans un bec distributeur 43. Le poussoir 4 est selon l'invention pourvu d'une tige axiale 7 qui est solidaire en déplacement, axial dudit poussoir. La tige est formée monobloc ou non avec ledit poussoir. La tige axiale 7 s'étend avantageusement à partir de la paroi d'appui 40 jusque dans le manchon 23. La tige axiale 7 présente une forme avantageusement cylindrique similaire à la forme du manchon 23. La tige axiale 7 forme l'organe mobile de clapet d'entrée 70 apte à coopérer avec le siège de clapet d'entrée 230 du manchon 23. L'organe mobile de clapet d'entrée 70 se présente avantageusement sous la forme d'au moins une rainure longitudinale ménagée le long de la tige axiale 7 sur une hauteur telle que du produit fluide puisse transiter par lesdites rainures pour rejoindre une chambre 6 localisée entre la tête de distribution 3 et le corps 2. La tige axiale 7 comporte également un siège de clapet de sortie 71, ledit siège de clapet de sortie 71 définissant alors avantageusement une surface cylindrique apte à coopérer avec un organe mobile de clapet de sortie 51. L'insert 5 est réalisé en un matériau élastiquement déformable. Il comporte avantageusement une couronne 53, une bride radiale 54 et une manchette 55. L'insert 5 est avantageusement emmanché dans le poussoir 4 de telle sorte que la couronne 53 vienne en prise avec la surface interne 411 de la jupe latérale 41 et que la bride radiale 54 vienne en prise avec la surface interne 401 de la paroi d'appui 40. La manchette 55 est pourvue d'un organe mobile de clapet de sortie comprenant une lèvre de clapet 51 annulaire apte à coopérer avec le siège de clapet de sortie 71 et se termine par une lèvre de piston 550 apte à coulisser de manière étanche dans le fût 22 du corps 2. Ainsi, une fois la tête de distribution 3 montée sur le corps 2, la chambre 6 s'étend autour de la tige axiale 7 occupant un volume allant d'une partie du plateau radial 22 située entre le fût 22 et le manchon 23 jusqu'au clapet de sortie 51, 71. L'insert 5 est selon l'exemple représenté traversé par un canal de sortie 52 permettant de faire communiquer un espace d'expulsion 50 avec l'orifice de distribution 42. L'espace d'expulsion 50 s'étend autour de la tige axiale formant ainsi un espace annulaire s'étendant du clapet de sortie 51, 71 jusqu'à la surface interne 1.401 de la paroi d'appui 40 du poussoir 4. Il est à noter qu'un réseau d'évidement 530 peut être réalisé au niveau de la couronne 53 de l'insert. Ce réseau forme un système de tourbillonnement 43 tel que représenté en figures 1 et 2. Sur la figure 3, c'est la paroi interne 411 de la jupe, au niveau de l'orifice de distribution 42, qui forme un système de tourbillonnement 43, qui est complété par la surface externe de la couronne 53, formée par l'insert 5. Sur la figure 4, la tête de distribution est dépourvue de système de tourbillonnement, mais comprend un bec distributeur 43 faisant communiquer directement le canal de sortie 52 avec l'orifice de distribution 42 situé au bout du bec. Un ressort de rappel 9 peut avantageusement s'étendre du plateau radial 22, entre la paroi périphérique 21 et le fût 22, jusqu'à la couronne 53 de l'insert 5 tel que représenté sur la figure 1 ou peut être logé entre le plateau radial 22 et l'extrémité inférieure de la jupe latérale 41 telle que représentée sur la figure 2. Dans ce dernier cas, il peut être envisagé de réaliser un ressort de rappel 9 et un poussoir 4 qui sont monobloc. Le fonctionnement du distributeur incorporant un organe de distribution selon l'invention sera maintenant décrit en référence aux figures 1, 2 et 3 représentant un organe de distribution dans une position de repos. Dans cette position de repos, une quantité de produit fluide est contenu dans la chambre 6, le clapet d'entrée 70, 230 est ouvert alors que le clapet de sortie 51, 71 est fermé. Quand l'utilisateur souhaite distribuer du produit, celui-ci actionne l'organe de distribution 1 par application d'une pression sur la paroi d'appui 40 du poussoir 4. Cette pression engendre un déplacement axial de la tête de distribution 3 par rapport au corps 2 immobile. Le déplacement de ladite tête de distribution entraîne donc un coulissement de la surface externe 410 de la jupe latérale 41 et de la lèvre de piston 550 de la manchette 55 respectivement contre la surface interne 211 de la paroi périphérique 21 et contre le fût 22. De plus, la tige axiale 7 solidaire du poussoir 4 s'enfonce dans le manchon 23. Le coulissement de la tige axiale 7 dans le manchon 23 entraîne une fermeture du clapet d'entrée 70, 230, le produit contenu danssle récipient 2 ne pouvant ainsi plus accéder à la chambre 6. La descente de la tête de distribution est en outre à l'origine d'une augmentation de pression dans la chambre 6 ayant pour effet d'ouvrir le clapet de sortie 51, 71. Ainsi, le produit fluide initialement présente dans la chambre 6 peut être chassé de celle-ci du fait d'une réduction de volume de ladite chambre 6. Le produit fluide f anchit alors le clapet de sortie ouvert puis gagne l'espace d'expulsion 50 avant d'être acheminé vers un canal de sortie 52. Le produit fluide dans le canal de sortie 52 rejoint alors le système de tourbillonnement centré sur l'orifice de distribution 42. Le produit fluide est ainsi expulsé. Cette expulsion peut se poursuivre jusqu'à mise en butée de l'extrémité inférieure de la jupe latérale 41 contre le plateau radial 22 synonyme d'évacuation complète ou quasi complète du produit contenu dans la chambre 6. Lorsque l'utilisateur cesse d'appuyer sur la paroi 40 du poussoir 4, le ressort de rappel 9 fait automatiquement remonter la tête de distribution 3. Cette remontée de la tête de distribution 3 engendre solidairement une remontée de la lèvre de piston 550 de la manchette 55 ayant alors pour effet d'ouvrir le clapet d'entrée 70, 230 et de fermer le clapet de sortie 51, 71. Le déplacement du piston 550 par rapport au corps 2 crée alors une dépression au niveau de la chambre 6 provoquant l'aspiration du produit renfermé dans le récipient. Ainsi, le produit gagne le tube plongeur 231 en empruntant le passage 232 et atteint le clapet d'entrée 70, 230 situé au niveau du manchon 23. Le produit traverse alors les rainures longitudinales de l'organe mobile de clapet d'entrée 70 pour enfin parvenir à la chambre 6. La chambre 6 se remplit tant que l'épaulement externe 4100 de la jupe latérale 41 ne vienne en butée contre la saillie interne 2100 de la paroi périphérique 21 du corps 2. Une fois que la tête de distribution 3 est en butée contre le corps 2, la position de repos est atteinte et un cycle peut de nouveau être enclenché par l'utilisateur. The present invention relates to a fluid dispenser member comprising the following components: a body intended for. be associated with a container, a dispensing head mounted movable in axial translation relative to the body, said head being movable relative to the body on an actuating stroke, said head comprising a pusher comprising a bearing wall defining an external surface support and an inner surface and a side skirt extending from said support wall, said side skirt having an outer surface and an inner surface, a chamber defined between said body and said head, said chamber being provided with 'at least one inlet and / or outlet valve, a dispensing orifice through which fluid is dispensed. The present invention also relates to a fluid dispenser incorporating such a dispensing member which can in particular be used in the pharmaceutical or cosmetic sectors. Many fluid product distribution systems, in particular which integrate a pump as a distribution member, exist in. the current time. These systems can have more or less distinct structural and functional characteristics, thus giving rise to devices which are more or less simple to assemble and more or less expensive. Fluid product dispensers include a container, a dispensing member, such as a pump or a valve, mounted on said container, and a pusher for actuating said dispensing member in order to dispense a volume of fluid product contained in the container through a dispensing orifice. In addition, most devices contain a chamber comprising an inlet valve and / or an outlet valve isolating the fluid contained in the container from the outside. Document WO 02/096776 discloses, for example, an embodiment of a dispensing device in which a central end piece is integrated into a pusher in order to serve as a movable member of an inlet valve. In this case, actuation of the pusher firstly causes contact with a piston which is then moved in axial translation. This displacement then generates simultaneously closing the inlet valve and opening the outlet valve. The descent of the piston is then at the origin of a reduction in volume of the pump chamber having the effect of expelling the fluid product contained in said chamber. Then, the pusher is returned to its initial rest position. The pusher disengages from the piston which remains momentarily stationary. The relative movement between the piston and the pusher generates the opening of the inlet valve, in order to put the chamber in communication with the container, and the simultaneous closing of the outlet valve to isolate the chamber from the outside. Thus, the piston remains stationary until a shoulder of the pusher abuts against a corresponding shoulder of the piston. The piston is then driven in translation and rises to its initial position, thereby causing a vacuum in the chamber at the origin of the suction of the fluid contained in the container. Thus, it turns out that this embodiment as described does not include precompression, the opening and closing of the inlet valve and the outlet valve being done simultaneously independently of any increase in pressure in the pressure chamber. pump. In addition, according to this invention, the movements of the piston and of the median endpiece are synchronous only over a short distance from the actuating stroke of the pusher, these two elements requiring to evolve at distinct axial translation speeds so that the ά-described pump works correctly. Consequently, the dispensing device that is the subject of this patent has a complex operating principle, thus causing difficulty in assembling and manufacturing said device as well as a substantially high cost price. The present invention aims to provide a dispensing member and a fluid dispenser incorporating such a dispensing member which does not reproduce the aforementioned drawbacks. In particular, the present invention aims to provide a dispensing member such as a precompression pump preventing any risk of contamination of the product and ensuring on the one hand a good seal and on the other hand a good reproducibility of the doses distributed to each actuation. The present invention also aims to provide a dispensing member and a distributor incorporating such a dispensing member which is simple to manufacture, to assemble and of relatively low cost. The present invention proposes to solve the aforementioned problems by developing a fluid product distribution member comprising the following components: - a body intended to be associated with a container, - a distribution head mounted movable in axial translation relative to the body, said head being movable relative to the body on an actuating stroke, said head comprising a pusher comprising a support wall defining an external support surface and an internal surface and a side skirt extending from said body support wall, said side skirt having an external surface and an internal surface, - a chamber defined between said body and said head, said chamber being provided with at least one inlet and / or outlet valve, - an orifice dispenser by which fluid is dispensed, characterized in that said pusher is provided with an axial rod, said rod aa ale forming said at least an inlet and / or outlet valve. in cooperation with at least one of the components, and in that said dispensing head comprises an insert associated integrally with the pusher. Advantageously, said insert and said axial rod are integral in their movement over the whole of the actuating stroke of said dispensing head. Advantageously, said axial rod comprises an outlet valve seat able to cooperate with said insert, said insert comprising a movable outlet valve member. Advantageously, said outlet valve seat comprises a cylindrical surface capable of cooperating with an annular lip of the movable outlet valve member in order to put said chamber in communication with an expulsion space which advantageously extends around said axial rod. . Advantageously, said insert comprises an outlet channel connecting said expulsion space to the dispensing orifice. Advantageously, the insert comprises a crown engaged with said internal surface of the side skirt, a radial flange engaged with said internal surface of the support wall and a cuff, said cuff comprising a piston lip in sealed sliding contact. with said body. Advantageously, the insert is a single deformable piece. Advantageously, said axial rod comprises a movable inlet valve member able to cooperate with an inlet valve seat formed by said body. Advantageously, said movable inlet valve member comprises at least one longitudinal groove capable of cooperating with an annular bead of the inlet valve seat to put said container in communication with said chamber. Advantageously, said side skirt includes said dispensing orifice. Advantageously, the crown of the insert comprises a swirl system, said swirl system being located opposite the dispensing orifice. As a variant, the internal surface of the side skirt comprises a swirl system facing the dispensing orifice, said swirl system being produced in a single piece in said side skirt. This is a characteristic which can be implemented independently of the fact that the pusher forms an axial valve stem. The swirl system is here completed by the insert which is fixedly received in the pusher. The present invention also relates to a fluid dispenser comprising a container and a fluid dispenser member according to the invention. In particular, the dispensing member can quite be adapted to miniature dispensers as used for the samples. Thus, the axial rod, which is preferably produced in a single piece by the pusher, has the function of a seat and / or of a movable member of an inlet valve. or exit. The insert fixedly engaged in the pusher is produced separately for reasons of molding techniques. However, it is not excluded that the insert can be made in one piece by the pusher, so that the dispensing head would then be formed in one piece. Other characteristics and advantages of the present invention will appear more clearly during the following detailed description of several exemplary embodiments of the present invention given by way of nonlimiting examples with reference to the accompanying drawings, and in which: FIG. 1 is a schematic overall view in cross section of a fluid dispenser incorporating a dispensing member according to the invention, Figure 2 is an enlarged view of the dispenser of Figure 1 and in particular of the dispensing member of this invention, FIG. 3 is an enlarged view of an alternative embodiment of the dispenser according to the invention, and FIG. 4 is an enlarged view of another alternative embodiment of the distributor according to the invention. With reference to the figures, a fluid product dispenser according to the present invention comprises two constituent elements, namely a dispensing member 1 and a container 8. The container 8 has an opening 80 making the inside of said container 8 communicate with the outside, a neck 83, a side wall 81 extending from the neck 83 and a bottom 82. The container 8 advantageously has a cylindrical shape and can be produced with any suitable material: metal, plastic, glass or the like. The side wall 81 comprises an external surface 810 in contact with the outside and an internal surface 811 defining a reservoir of fluid product. The neck 83 advantageously has a hooking section on the side of its external surface 810 intended to receive the dispensing member 1. The dispensing member 1 comprises a body 2 intended to be associated with the container 8 and a dispensing head 3 . The body 2 can be fixed on the neck 83 of the container 8 by any means. The body 2 has a symmetrical axial revolution and is capable of being fitted onto the neck of the container 8. The body 2 comprises a radial plate 20 from which extends a peripheral wall 21, a ft 22 and a sleeve 23 The peripheral wall 21 extends upwards and downwards from the radial plate 20. The peripheral wall 21 has an external surface 210 and an internal surface 211. The bottom part of the wall 21 is advantageously fitted on the neck of the container 2 so that the radial plate 22 comes to rest on the neck of the container and the internal surface 211 comes into engagement with the external surface 810 of the container 8. Advantageously, it follows from this fitting that the external surface 210 of the peripheral wall 21 of the body 2 is placed in the continuity of the external surface 810 of the container 8 in order to give the dispenser a generally regular shape, advantageously cylindrical. The peripheral wall 21 may also include at its internal surface 211 an internal projection 2100 intended to serve as an upper stop for the dispensing head 3. The barrel 22 defines a sealed sliding surface for a cuff 55 forming a piston element. s The sleeve 23 forms an inlet valve seat 230 able to cooperate with a movable inlet valve member 70. The valve seat 230 advantageously has the form of an annular bead. The sleeve 23 advantageously extends downward into the container so as to form a dip tube 231 having a passage 232 through which fluid can pass. The body 2 as described is advantageously made in one piece in order to facilitate the assembly of the dispensing member. The body 2 can be made of any suitable material: metal, plastic, or the like. The dispensing head 3 advantageously comprises two constituent elements, namely a pusher 4 and an insert 5. The dispensing head 3 is movably mounted on the body 2 so as to be able to move axially relative to the body 2 over a stroke d actuation A. The pusher 4 has a support wall 40 defining an internal surface 401 and an external support surface 400 and a side skirt 41 extending downward from said support wall 40. The side skirt 41 has a external surface 410 and an internal surface 411. The external surface 410 advantageously has an external shoulder 4100 intended to cooperate with the internal projection 2100 of the peripheral wall 21 of the body 2 to form a high stop. Thus, this stop makes it possible to define the rest position of the dispensing member 1 and guarantees an anti-tearing function of the dispensing head. It should be noted that in the embodiment as shown, part of the internal surface 211 located between the internal projection 2100 and the radial plate 22, serves as a guide wall for the pusher 4 thus guaranteeing a better axial orientation of the pusher while moving. A dispensing orifice 42 is advantageously provided at the side skirt 41. The dispensing orifice 42 can then be located at the end of a channel in a dispensing spout 43. The pusher 4 is according to the invention provided with a axial rod 7 which is integral in displacement, axial of said pusher. The rod is formed in one piece or not with said pusher. The axial rod 7 advantageously extends from the bearing wall 40 into the sleeve 23. The axial rod 7 has an advantageously cylindrical shape similar to the shape of the sleeve 23. The axial rod 7 forms the movable member of inlet valve 70 able to cooperate with the inlet valve seat 230 of the sleeve 23. The movable inlet valve member 70 is advantageously in the form of at least one longitudinal groove formed along the rod axial 7 over a height such that fluid can pass through said grooves to reach a chamber 6 located between the dispensing head 3 and the body 2. The axial rod 7 also includes an outlet valve seat 71, said valve seat outlet 71 then advantageously defining a cylindrical surface capable of cooperating with a movable outlet valve member 51. The insert 5 is made of an elastically deformable material. It advantageously comprises a crown 53, a radial flange 54 and a cuff 55. The insert 5 is advantageously fitted into the pusher 4 so that the crown 53 comes into engagement with the internal surface 411 of the side skirt 41 and that the radial flange 54 comes into engagement with the internal surface 401 of the support wall 40. The cuff 55 is provided with a movable outlet valve member comprising an annular valve lip 51 capable of cooperating with the outlet valve seat 71 and ends with a piston lip 550 capable of sliding in leaktight manner in the barrel 22 of the body 2. Thus, once the dispensing head 3 mounted on the body 2, the chamber 6 extends around the axial rod 7 occupying a volume ranging from a part of the radial plate 22 located between the barrel 22 and the sleeve 23 up to the outlet valve 51, 71. The insert 5 is, according to the example shown, traversed by an outlet channel 52 allowing to communicate an ex space outlet 50 with the dispensing orifice 42. The expulsion space 50 extends around the axial rod thus forming an annular space extending from the outlet valve 51, 71 to the internal surface 1.401 of the wall 40 for supporting the pusher 4. It should be noted that a recess network 530 can be produced at the level of the crown 53 of the insert. This network forms a swirl system 43 as shown in Figures 1 and 2. In Figure 3, it is the inner wall 411 of the skirt, at the distribution orifice 42, which forms a swirl system 43 , which is completed by the external surface of the crown 53, formed by the insert 5. In FIG. 4, the dispensing head is devoid of a swirl system, but includes a dispensing spout 43 directly communicating the outlet channel 52 with the dispensing orifice 42 located at the end of the spout. A return spring 9 can advantageously extend from the radial plate 22, between the peripheral wall 21 and the barrel 22, up to the crown 53 of the insert 5 as shown in FIG. 1 or can be housed between the plate radial 22 and the lower end of the side skirt 41 as shown in FIG. 2. In the latter case, it can be envisaged to produce a return spring 9 and a pusher 4 which are in one piece. The operation of the dispenser incorporating a dispensing member according to the invention will now be described with reference to Figures 1, 2 and 3 showing a dispensing member in a rest position. In this rest position, a quantity of fluid is contained in the chamber 6, the inlet valve 70, 230 is open while the outlet valve 51, 71 is closed. When the user wishes to dispense product, the latter actuates the dispensing member 1 by applying pressure to the support wall 40 of the pusher 4. This pressure generates an axial displacement of the dispensing head 3 relative to to the stationary body 2. The displacement of said dispensing head therefore causes the external surface 410 of the side skirt 41 and the piston lip 550 of the cuff 55 to slide against the internal surface 211 of the peripheral wall 21 and against the barrel 22 respectively. more, the axial rod 7 integral with the pusher 4 sinks into the sleeve 23. The sliding of the axial rod 7 in the sleeve 23 causes the inlet valve 70, 230 to close, the product contained in the container 2 thus being unable to more access to the chamber 6. The descent of the dispensing head is also at the origin of an increase in pressure in the chamber 6 having the effect of opening the outlet valve 51, 71. Thus, the fluid product initially present in the chamber 6 can be expelled from the latter due to a reduction in volume of the said chamber 6. The fluid product then anchors the outlet valve open then gains the expulsion space 50 before being routed to a outlet channel 52. The fluid in the outlet channel 52 then joins the swirl system centered on the dispensing orifice 42. The fluid is thus expelled. This expulsion can continue until the lower end of the lateral skirt 41 abuts against the radial plate 22 synonymous with complete or almost complete evacuation of the product contained in the chamber 6. When the user stops pressing on the wall 40 of the pusher 4, the return spring 9 automatically raises the dispensing head 3. This raising the dispensing head 3 causes the piston lip 550 of the cuff 55 to rise together having the effect of opening the inlet valve 70, 230 and closing the outlet valve 51, 71. The displacement of the piston 550 relative to the body 2 then creates a depression at the level of the chamber 6 causing the aspiration of the product contained in the container. Thus, the product reaches the dip tube 231 via the passage 232 and reaches the inlet valve 70, 230 located at the sleeve 23. The product then passes through the longitudinal grooves of the movable member of the inlet valve 70 for finally reach the chamber 6. The chamber 6 fills as long as the external shoulder 4100 of the side skirt 41 does not come into abutment against the internal projection 2100 of the peripheral wall 21 of the body 2. Once the dispensing head 3 is in abutment against the body 2, the rest position is reached and a cycle can again be started by the user.
