  • the attachment means generally comprise one or more attachment profile (s), which allow the latching or screwing of the skirt on or 4ans the neck of the tank.
  • a problem associated with such a method of attachment lies in the assembly of the dispensing member around the neck of the reservoir. In fact, during such an assembly, the dispensing member must be prepositioned perfectly in the axis of the neck of the reservoir before fitting or screwing onto said neck to avoid any incorrect positioning of said dispensing member. Indeed, a tilted prepositioning of the dispensing member can cause sealing problems and can even in some cases cause the dispensing member and / or the reservoir to break.
  • the dispensing member includes a body internally defining a fluid chamber. This body extends into the fixing skirt, projecting widely downwards. At its lower end, the body forms a fluid inlet into the chamber. This entry can be provided with a dip tube.
  • the body at the level of the skirt, has a relatively large diameter. However, the body, at this level, is inserted into the neck of the tank once the skirt is fixed on the neck. Since the body extends below the skirt, the body is used to guide the skirt when it is mounted on the collar.
  • the introduction of the body into the collar makes it possible to preposition the skirt on the collar. Because it has a relatively large diameter compared to the internal diameter of the neck, the body alone ensures the maintenance in the axis of the skirt relative to the neck.

Description

Organe de distribution de produit fluide et distributeur comprenant un tel organe Fluid product distribution member and distributor comprising such a member
La présente invention concerne un organe de distribution de produit fluide, tel qu'une pompe ou une valve, destiné à être monté sur ou associé à un col de réservoir. La présente invention concerne également un distributeur comportant un tel organe de distribution. Cette invention s'applique particulièrement mais pas exclusivement, aux domaines de la cosmétique, de la parfumerie et de la pharmacie. Selon l'art antérieur, l'organe de distribution peut être fixé sur un col de réservoir de diverses manières. Par exemple, la fixation peut se faire par vissage, par sertissage ou encore par encliquetage. Cette fixation met habituellement en œuvre une jupe de fixation apte à solidariser l'organe de distribution au réservoir. Toutefois, cette fixation peut également se faire par des moyens de fixation directement formés par l'organe de distribution. Les moyens d'accrochage comprennent généralement un ou plusieurs profile(s) d'accrochage, qui permettent l'encliquetage ou le vissage de la jupe sur ou 4ans le col du réservoir. Un problème lié à un tel mode de fixation réside dans l'assemblage de l'organe de distribution autour du col du réservoir. En effet, lors d'un tel assemblage, l'organe de distribution doit être prépositionné parfaitement dans l'axe du col du réservoir avant emmanchage ou vissage sur ledit col pour éviter tout mauvais positionnement dudit organe de distribution. En effet, un prépositionnement penché de l'organe de distribution peut occasionner des problèmes d'étanchéité et peut même dans certains cas entraîner la cassure de l'organe de distribution et/ou du réservoir. Or, il est bien souvent difficile, de par la présence du profil d'accrochage, d'avoir un organe de distribution prépositionné droit sur le col permettant un enfoncement ou un vissage axial adéquate et un positionnement définitif parfait de l'organe de distribution. En général, l'organe de distribution comprend un corps définissant intérieurement une chambre de produit fluide. Ce corps s'étend dans la jupe de fixation en faisant largement saillie vers le bas. A son extrémité inférieure, le corps forme une entrée de produit fluide dans la chambre. Cette entrée peut être pourvue d'un tube-plongeur. Le corps, au niveau de la jupe, présente un diamètre relativement important. Or, le corps, à ce niveau, est inséré dans le col du réservoir une fois la jupe fixée sur le col. Etant donné que le corps s'étend en-dessous de la jupe, on se sert du corps pour guider la jupe lors de son montage sur le col. Ainsi, l'introduction du corps dans le col permet de prépositionner la jupe sur le col. Du fait qu'il présente un diamètre relativement important par rapport au diamètre interne du col, le corps assure à lui seul le maintien dans l'axe de la jupe par rapport au col. Le corps remplit donc un rôle de centreur ou de guide pour le prépositionnement de la jupe sur le col, avant son montage définitif. Le but de la présente invention est de s'affranchir de la fonction de guidage ou de prépositionnement du corps dans le col tout en garantissant le prépositionnement axial centré de la jupe sur le col. Ceci est particulièrement utile lorsque le corps de l'organe de distribution ne s'étend pas dans la jupe ou le col. Pour atteindre ce but, la présente invention propose un organe de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés. Plus particulièrement, la présente invention a pour but de fournir un organe de distribution facile à prépositionner et à positionner sur un réservoir. La présente invention a également pour but de fournir un organe de distribution et un distributeur simple et peu coûteux à fabriquer et à assembler. Pour atteindre ces buts, la présente invention propose un organe de distribution de produit fluide destiné à être monté sur un col de réservoir, ledit organe comprenant des moyens de fixation pour fixer l'organe sur le col de réservoir, lesdits moyens de fixation comprenant une jupe périphérique destinée à s'étendre autour du col de réservoir, ladite jupe comprenant au moins un profil d'accrochage destiné à venir en prise avec le col, caractérisé en ce que la jupe comprend en outre une section de guidage destinée à venir en prise autour du col alors que ledit au moins un profil d'accrochage n'est pas encore en prise avec le col. Cette section de guidage, qui peut se présenter sous la forme d'un prolongement de la jupe vers le bas sous les moyens de fixation de l'organe de distribution, assure ainsi un prépositionnement axial droit et stable de l'organe de distribution sur le col du réservoir. Ainsi, la section de guidage fera en sorte que l'axe de l'organe de distribution soit sensiblement ou parfaitement confondu avec l'axe du réservoir. Donc, l'organe de distribution sera plus facilement amené en position sur le col et le risque de casse du réservoir ou de la jupe, suite à un mauvais prépositionnement de l'organe de distribution, sera évité. Cette section de guidage permet de se passer du corps de l'organe de distribution. Avantageusement, la jupe s'étend vers le bas à partir d'une paroi d'appui destinée à venir en appui sur le col, la jupe définissant ainsi une extrémité libre, ladite section de guidage s 'étendant à partir de ladite extrémité fibre jusqu'au profil d'accrochage. Avantageusement, les moyens de fixation comprennent une douille d'étanchéité destinée à venir en contact étanche avec une paroi interne du col.The present invention relates to a fluid dispenser member, such as a pump or a valve, intended to be mounted on or associated with a tank neck. The present invention also relates to a dispenser comprising such a dispensing member. This invention applies particularly but not exclusively, to the fields of cosmetics, perfumery and pharmacy. According to the prior art, the dispensing member can be fixed to a tank neck in various ways. For example, the fixing can be done by screwing, crimping or even by snap-fastening. This attachment usually implements an attachment skirt capable of securing the dispensing member to the reservoir. However, this fixing can also be done by fixing means directly formed by the dispensing member. The attachment means generally comprise one or more attachment profile (s), which allow the latching or screwing of the skirt on or 4ans the neck of the tank. A problem associated with such a method of attachment lies in the assembly of the dispensing member around the neck of the reservoir. In fact, during such an assembly, the dispensing member must be prepositioned perfectly in the axis of the neck of the reservoir before fitting or screwing onto said neck to avoid any incorrect positioning of said dispensing member. Indeed, a tilted prepositioning of the dispensing member can cause sealing problems and can even in some cases cause the dispensing member and / or the reservoir to break. However, it is very often difficult, due to the presence of the attachment profile, to have a dispensing member prepositioned straight on the neck allowing adequate insertion or axial screwing and perfect final positioning of the dispensing member. In general, the dispensing member includes a body internally defining a fluid chamber. This body extends into the fixing skirt, projecting widely downwards. At its lower end, the body forms a fluid inlet into the chamber. This entry can be provided with a dip tube. The body, at the level of the skirt, has a relatively large diameter. However, the body, at this level, is inserted into the neck of the tank once the skirt is fixed on the neck. Since the body extends below the skirt, the body is used to guide the skirt when it is mounted on the collar. Thus, the introduction of the body into the collar makes it possible to preposition the skirt on the collar. Because it has a relatively large diameter compared to the internal diameter of the neck, the body alone ensures the maintenance in the axis of the skirt relative to the neck. The body therefore fulfills a role of centering or guide for the prepositioning of the skirt on the collar, before its final assembly. The object of the present invention is to dispense with the function of guiding or prepositioning the body in the neck while guaranteeing the axial prepositioning centered on the skirt on the neck. This is particularly useful when the body of the dispensing member does not extend into the skirt or the collar. To achieve this object, the present invention provides a fluid dispenser member which does not reproduce the aforementioned drawbacks. More particularly, the present invention aims to provide a dispensing member that is easy to preposition and position on a reservoir. The present invention also aims to provide a distribution member and a distributor that is simple and inexpensive to manufacture and assemble. To achieve these goals, the present invention provides a fluid dispenser member intended to be mounted on a tank neck, said member comprising fixing means for fixing the member on the tank neck, said fixing means comprising a peripheral skirt intended to extend around the tank neck, said skirt comprising at least one attachment profile intended to come into engagement with the neck, characterized in that the skirt further comprises a guide section intended to come into engagement around the neck while said at least one attachment profile is not yet engaged with the collar. This guide section, which can be in the form of an extension of the skirt downwards under the fixing means of the dispensing member, thus ensures a straight and stable axial prepositioning of the dispensing member on the tank neck. Thus, the guide section will ensure that the axis of the dispensing member is substantially or perfectly coincident with the axis of the reservoir. Therefore, the dispensing member will be more easily brought into position on the neck and the risk of breakage of the reservoir or of the skirt, following incorrect prepositioning of the dispensing member, will be avoided. This guide section makes it possible to dispense with the body of the dispensing member. Advantageously, the skirt extends downwards from a support wall intended to come to bear on the neck, the skirt thus defining a free end, said guide section extending from said fiber end up to 'to the attachment profile. Advantageously, the fixing means comprise a sealing sleeve intended to come into sealing contact with an internal wall of the neck.
Cette douille garantit ainsi une parfaite étanchéité du réservoir et interdit donc toutes possibilités de fuite de produit fluide au niveau du col du réservoir. Donc, cette douille permet de se dispenser de l'utilisation d'un joint de col interposé entre le col et les moyens de fixation. Avantageusement, la douille s'étend vers le bas à partir d'une paroi d'appui destinée à venir en appui sur le col, la douille définissant ainsi une extrémité libre qui s'étend sensiblement au même niveau que rextrémité libre de la jupe. Avantageusement, l'organe de distribution comprend un corps de chambre de produit fluide pourvu d'une entrée de produit fluide à travers laquelle du produit fluide stocké dans le réservoir peut être extrait, ladite entrée étant disposée à un niveau axial situé sur la hauteur de la jupe. Avantageusement, l'organe de distribution comprend un corps de chambre de produit fluide pourvu d'une entrée de produit fluide à travers laquelle du produit fluide est amené dans le corps de chambre, ladite entrée étant disposée à un niveau axial situé au-dessus de la paroi d'appui. Cet emplacement de l'entrée du corps de chambre permet ainsi de faire en sorte que l'entrée du corps de chambre, voire le corps de chambre lui-même, ne sont pas disposés dans l'ouverture du col du réservoir, mais au-dessus. Ainsi, le réservoir étant souvent réalisé en matériau transparent, tel que du verre ou du plastique, cette caractéristique a pour avantage que l'entrée du corps de chambre et le corps de chambre ne pourront pas être vus de l'extérieur à travers le réservoir. En effet, ces éléments viendront avantageusement se loger dans un volume délimité par la tête de distribution et donc ne seront pas visibles de l'extérieur, la tête de distribution étant bien souvent réalisée en matériau opaque ou revêtu d'une couleur opacifiante. Avantageusement, le corps de chambre est réalisé de manière monobloc avec les moyens de fixation. Avantageusement, l'entrée est pourvue d'un tube-plongeur destiné à s'étendre dans le réservoir. La présente invention propose également un distributeur de produit fluide comprenant un réservoir de produit fluide ayant un col et un organe de distribution. Avantageusement, le distributeur comprend un tube-plongeur qui s'étend dans le réservoir et une douille d'étanchéité en contact étanche dans le col, seuls le tube-plongeur et la douille s'étendant dans le col. Avantageusement, les moyens de fixation comprennent une douille d'étanchéité destinée à venir en contact étanche avec une paroi interne du col, ladite douille ayant une extrémité libre qui pénètre dans le col lorsque la section de guidage de la jupe est en prise autour du col avec ledit au moins un profil d'accrochage en butée sur le col. L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non Hmitatif un mode de réalisation de l'invention. Sur les figures : - la figure 1 est une vue en coupe transversale verticale à travers un distributeur comportant un organe de distribution selon l'invention prépositionné sur un réservoir de produit fluide, - la figure 2 est une vue agrandie d'une partie du réservoir et de l'organe de distribution de la figure 1, - la figure 3 est une vue similaire à celle de la figure 1 du distributeur avec un organe de distribution selon l'invention définitivement monté sur le réservoir de produit fluide, et - la figure 4 est vue similaire à la figure 2 d'une partie du réservoir et de l'organe de distribution de la figure 3. En référence aux figures, un distributeur selon l'invention comporte un organe de distribution et un réservoir 1. Le réservoir 1 est destiné à contenir du produit fluide à distribuer. Il peut être réalisé en verre, en métal ou en matériau plastique. Sa contenance peut être de l'ordre de deux à trois millilitres dans le cas d'échantillons ou peut être bien supérieure dans le cas de réservoirs conventionnels. Ce réservoir peut présenter toutes formes appropriées. Le réservoir 1 tel que représenté sur les figures 1 et 3 comportent une extrémité inférieure obturée par un fond 11 et une extrémité supérieure définissant un col 13. Un épaulement 12 fait avantageusement la liaison entre le corps 10 et le col 13. Le col 13 définit une ouverture apte à faire communiquer le milieu extérieur avec l'intérieur du réservoir. Ce col comprend un bord supérieur 130, une paroi interne 133 et une paroi externe 131. La paroi externe 131 présente une surépaisseur par rapport au reste du réservoir. Un logement 132 formant une portion évidée est avantageusement ménagé entre la surépaisseur et l'épaulement 12. L'organe de distribution peut être une pompe ou une valve. Cet organe comporte un corps d'organe 2, un piston 3, un ressort 5 et une tête de distribution 6. Le corps d'organe 2 comporte avantageusement des moyens de fixation, un corps de chambre et un tube-plongeur 24. Les moyens de fixation comprennent une jupe périphérique 20 et une douille d'étanchéité 21. La jupe périphérique 20 peut comporter d'une part une partie inférieure et d'autre part une partie supérieure. La partie inférieure comprend une surface externe 200, une surface interne 201 et une extrémité fibre 202. La surface interne 201 comporte un profil d'accrochage 2010. Ce profil d'accrochage peut par exemple correspondre à une projection interne telle que représentée sur les figures ou bien correspondre à plusieurs projections internes. Selon invention, une section de guidage 2011 est prévue ente le profil d'accrochage 2010 et rextrémité libre 202. La partie supérieure comprend une face externe 203, avantageusement pourvue d'un renflement de butée 2030, une face interne 204 et d'une extrémité supérieure 205. Tel que représenté sur les différentes figures, les parties inférieure et supérieure peuvent être réalisées monobloc et être reliées ensemble par un décrochement transversal 206. Le décrochement 206 comporte une paroi de butée 2060 et une paroi d'appui 2061. La douille d'étanchéité 21 est concentrique à la jupe périphérique 20.This socket thus guarantees a perfect seal of the tank and therefore prohibits any possibility of leakage of fluid product at the neck of the tank. Therefore, this socket makes it possible to dispense with the use of a neck gasket interposed between the neck and the fixing means. Advantageously, the sleeve extends downward from a bearing wall intended to come to bear on the neck, the sleeve thus defining a free end which extends substantially at the same level as the free end of the skirt. Advantageously, the dispensing member comprises a fluid product chamber body provided with a fluid product inlet through which fluid product stored in the reservoir can be extracted, said inlet being disposed at an axial level situated on the height of the skirt. Advantageously, the dispensing member comprises a fluid product chamber body provided with a fluid product inlet through which fluid product is brought into the chamber body, said inlet being disposed at an axial level situated above the support wall. This location of the inlet of the chamber body thus makes it possible to ensure that the inlet of the chamber body, or even the chamber body itself, is not disposed in the opening of the neck of the reservoir, but above. Thus, the reservoir often being made of transparent material, such as glass or plastic, this characteristic has the advantage that the entry of the chamber body and the chamber body cannot be seen from the outside through the reservoir. . Indeed, these elements will advantageously be housed in a volume delimited by the dispensing head and therefore will not be visible from the outside, the dispensing head very often being made of opaque material or coated with an opacifying color. Advantageously, the chamber body is produced in a single piece with the fixing means. Advantageously, the inlet is provided with a dip tube intended to extend into the tank. The present invention also provides a fluid dispenser comprising a fluid reservoir having a neck and a dispensing member. Advantageously, the dispenser comprises a dip tube which extends into the reservoir and a sealing sleeve in leaktight contact in the neck, only the dip tube and the sleeve extending in the neck. Advantageously, the fixing means comprise a sealing sleeve intended to come into sealing contact with an internal wall of the neck, said sleeve having a free end which penetrates into the neck when the guide section of the skirt is engaged around the neck. with said at least one attachment profile in abutment on the neck. The invention will now be described more fully with reference to the accompanying drawings which give by way of non-limiting example an embodiment of the invention. In the figures: - Figure 1 is a vertical cross-sectional view through a dispenser comprising a dispensing member according to the invention prepositioned on a fluid reservoir, - Figure 2 is an enlarged view of part of the reservoir and the dispenser member of Figure 1, - Figure 3 is a view similar to that of Figure 1 of the dispenser with a dispenser member according to the invention permanently mounted on the fluid reservoir, and - Figure 4 is similar view in FIG. 2 of a part of the reservoir and of the dispensing member of FIG. 3. With reference to the figures, a dispenser according to the invention comprises a dispensing member and a reservoir 1. The reservoir 1 is intended to contain of the fluid to be dispensed. It can be made of glass, metal or plastic. Its capacity can be of the order of two to three milliliters in the case of samples or can be much greater in the case of conventional tanks. This reservoir can have any suitable shape. The tank 1 as shown in Figures 1 and 3 has a lower end closed by a bottom 11 and an upper end defining a neck 13. A shoulder 12 advantageously makes the connection between the body 10 and the neck 13. The neck 13 defines an opening capable of communicating the outside environment with the inside of the tank. This neck comprises an upper edge 130, an internal wall 133 and an external wall 131. The external wall 131 has an increased thickness relative to the rest of the reservoir. A housing 132 forming a hollowed out portion is advantageously provided between the additional thickness and the shoulder 12. The dispensing member may be a pump or a valve. This member comprises a member body 2, a piston 3, a spring 5 and a dispensing head 6. The body of the body 2 advantageously comprises fixing means, a chamber body and a dip tube 24. The fixing means comprise a peripheral skirt 20 and a sealing sleeve 21. The peripheral skirt 20 may include a share a lower part and secondly an upper part. The lower part comprises an external surface 200, an internal surface 201 and a fiber end 202. The internal surface 201 comprises an attachment profile 2010. This attachment profile may for example correspond to an internal projection as shown in the figures or correspond to several internal projections. According to the invention, a guide section 2011 is provided between the attachment profile 2010 and free end 202. The upper part comprises an external face 203, advantageously provided with a stop bulge 2030, an internal face 204 and an end upper 205. As shown in the different figures, the lower and upper parts can be made in one piece and be connected together by a transverse recess 206. The recess 206 comprises a stop wall 2060 and a support wall 2061. The socket d the seal 21 is concentric with the peripheral skirt 20.
Cette douille comporte un versant externe 210, un versant interne 211 et une extrémité libre 212. L'extrémité libre 212 s'étend avantageusement vers le bas au même niveau que rextrémité libre 202 de la jupe 20 ou à un niveau moindre. Le corps de chambre 2 comprend un fût de coulissement 22 et un manchon 23 reliés ensemble à une bride radiale 232. Ce corps de chambre est, tel que représenté, avantageusement réalisé de manière monobloc avec les moyens de fixation. Le manchon 23 comporte avantageusement une entrée de produit fluide 230. Cette entrée 230 est avantageusement pourvue d'un tube-plongeur 24. Le tube-plongeur 24 prolonge ainsi le manchon 23 et s'étend sensiblement en- dessous des extrémités libres respectives 202 et 212 de la jupe 20 et de la douille 21. Le tube-plongeur 24 peut être réalisé monobloc avec le manchon 23 ou bien peut venir se fixer à l'intérieur du manchon 23. Selon un mode de réalisation particulièrement intéressant, l'entrée de produit fluide 230 est disposé à un niveau axial situé sur la hauteur de la jupe 20, entre rextrémité libre 202 et rextrémité supérieure 205. L'entrée 230 peut même se situer à un niveau axial situé au-dessus de l'extrémité supérieure 205. D'une manière générale, l'entrée 230 est avantageusement disposée à un niveau axial situé au-dessus de la paroi d'appui 2061. Un piston 3 est également prévu. La réalisation de ce piston n'est pas l'objet de l'invention et ne sera donc pas explicité de manière détaillée. Dans l'exemple représenté, le piston 3 forme un piston principal 32, un piston différentiel 31. Le piston 3 et le corps de chambre délimitent ensemble un espace formant une chambre de pompe 4. Le piston 3 est avantageusement monté coulissant dans le corps de chambre et permet au piston principale 32 de coulisser de façon étanche dans un fut 22. Ce coulissement du piston permet ainsi de sélectivement diminuer et augmenter le volume de ladite chambre 4. Le piston définit également une tige de clapet 30 qui sert d'organe mobile de clapet d'entrée par coopération avec un siège de clapet du manchon 23 permettant ainsi l'entrée sélective de produit fluide. Le piston différentiel 31 forme un organe mobile de clapet de sortie coopérant avec un fut différentiel 612 formé par la tête de distribution 6. Le piston 3 est sollicité en position de repos par un moyen de rappel 4 tel qu'un ressort. Le ressort 4 est avantageusement placé entre le piston 3 et le corps d'organe 2. Au niveau du corps d'organe 2, ce ressort peut être hébergé entre la face interne 204 de la partie supérieure de la jupe 20 et le fût 22 du corps de chambre. Au niveau du piston 3, ce ressort peut être disposé sous le bras de piston 31. La tête de distribution 6, selon le mode de réalisation représenté, coiffe le corps d'organe 2 et le piston 3. Cette tête de distribution comprend une surface d'actionnement 60 sur laquelle l'utilisateur peut appuyer et une couronne latérale 61. La couronne latérale 61 comporte avantageusement un orifice latéral de sortie de produit 610 et une extrémité inférieure 611 formant un élément de retenue 6110. L'orifice latéral de sortie peut être un simple trou communiquant ou un conduit de sortie de produit fluide ou bien appartenir à un système de canaux et de chambre de tourbillonnement. Cet élément de retenue 6110 peut coopérer avec le renflement de butée 2030 pour définir la position de repos de la tête de distribution. La paroi interne de la couronne forme un fût différentiel 612 dans lequel coulisse le piston différentiel 31. Lors de l'enfoncement de la surfaceThis sleeve has an external slope 210, an internal slope 211 and a free end 212. The free end 212 advantageously extends downwards to the same level as the free end 202 of the skirt 20 or to a lesser level. The chamber body 2 comprises a sliding barrel 22 and a sleeve 23 connected together to a radial flange 232. This chamber body is, as shown, advantageously produced in a single piece with the fixing means. The sleeve 23 advantageously comprises a fluid product inlet 230. This inlet 230 is advantageously provided with a dip tube 24. The dip tube 24 thus extends the sleeve 23 and extends substantially below the respective free ends 202 and 212 of skirt 20 and socket 21. The dip tube 24 can be made in one piece with the sleeve 23 or can be fixed inside the sleeve 23. According to a particularly advantageous embodiment, the fluid inlet 230 is disposed at an axial level located on the height of the skirt 20, between the free end 202 and the top end 205. The inlet 230 may even be situated at an axial level situated above the upper end 205. In general, the inlet 230 is advantageously arranged at an axial level situated above the support wall 2061. A piston 3 is also provided. The production of this piston is not the subject of the invention and will therefore not be explained in detail. In the example shown, the piston 3 forms a main piston 32, a differential piston 31. The piston 3 and the chamber body together delimit a space forming a pump chamber 4. The piston 3 is advantageously slidably mounted in the body of chamber and allows the main piston 32 to slide tightly in a barrel 22. This sliding of the piston thus makes it possible to selectively decrease and increase the volume of said chamber 4. The piston also defines a valve stem 30 which serves as a movable member inlet valve by cooperation with a valve seat of the sleeve 23 thus allowing the selective entry of fluid. The differential piston 31 forms a movable outlet valve member cooperating with a differential barrel 612 formed by the dispensing head 6. The piston 3 is biased in the rest position by a return means 4 such as a spring. The spring 4 is advantageously placed between the piston 3 and the organ body 2. At the organ body 2, this spring can be accommodated between the internal face 204 of the upper part of the skirt 20 and the barrel 22 of the chamber body. At the piston 3, this spring can be placed under the piston arm 31. The dispensing head 6, according to the embodiment shown, covers the body of the body 2 and the piston 3. This dispensing head comprises a surface actuator 60 on which the user can press and a lateral crown 61. The lateral crown 61 advantageously comprises a lateral product outlet orifice 610 and a lower end 611 forming a retaining element 6110. The lateral outlet orifice can be a simple communicating hole or a fluid outlet conduit or belong to a system of channels and swirl chamber. This retaining element 6110 can cooperate with the abutment bulge 2030 to define the rest position of the dispensing head. The internal wall of the crown forms a differential barrel 612 in which the differential piston 31 slides. When the surface is pressed in
60 de la tête de distribution, l'extrémité inférieure 611 vient avantageusement en fin de course en butée contre la paroi de butée 2060. Cette butée définit ainsi une position de compression maximale de ladite tête. Selon un mode de réalisation avantageux, la couronne latérale 61 présente un diamètre externe similaire au diamètre externe de la partie inférieure de la jupe 20. Ainsi, lorsque la tête de distribution 6 est montée sur le corps d'organe 2, la couronne 61 peut venir se placer dans la continuité de la surface externe 200 de la partie inférieure de la jupe 20 lors de l'enfoncement maximal de ladite tête de distribution. Il en résulte ainsi un avantage esthétique. L'organe de distribution qui vient d'être décrit est une pompe : une valve est également envisageable dans le cadre de l'invention. L'organe de distribution est ensuite monté sur le réservoir 1 par coopération des moyens de fixation avec le col 13 du réservoir. Ce montage peut être scindé en deux étapes : une étape de prépositionnement de l'organe de distribution représenté sur les figures 1 et 2 et une étape de positionnement définitif de l'organe de distribution illustrée en figures 3 et 4. Lors du prépositionnement de l'organe de distribution, la section de guidage 2011 de la jupe 20 vient tout d'abord en prise autour du col 13. Cette coopération de la section de guidage 2011 avec la surface externe 131 du col a ainsi Heu avant que le profil d'accrochage 2010 soit en prise avec le col 13. En effet, le profil d'accrochage 2010 lors de cette étape positionné au-dessus du bord supérieur 130. Ce prépositionnement prévoit ainsi la coopération de deux surfaces avantageusement cylindriques, garantissant ainsi un prépositionnement stable et droit de l'organe de distribution par rapport au réservoir 1. En outre, lors de cette étape, le versant externe 210 de la douille d'étanchéité 21 vient presque en contact étanche contre la paroi interne 133 du col 13. Ce contact étanche garantit donc lors de cette étape de prépositionnement une étanchéité au niveau du col du réservoir. Ensuite, le passage de l'étape de prépositionnement de l'organe de distribution à l'étape de positionnement définitif dudit organe de distribution se fait par l'exercice d'une pression axiale. Cette pression axiale exercée sur la tête de distribution 6 se traduit par un coulissement de la surface interne 201 de la jupe le long de la paroi externe 131 du col 13. Le profil d'accrochage 2010 vient alors en appui contre la paroi externe 131 pour venir finalement s'encliqueter dans le logement 133 du col. Ce logement interdit avantageusement toutes possibilités de retrait de l'organe de distribution par traction axiale. En effet, le profil d'accrochage 2011 est avantageusement prisonnier du logement 133. Donc, l'organe 2 peut être ainsi maintenu fixement sur le col 13. Selon un mode de réalisation avantageux, la paroi d'appui 2061 de la jupe 20 vient reposer sur le bord supérieur 130 du col lors de ce positionnement définitif. De plus, l'extrémité libre 202 peut venir en butée contre l'épaulement60 of the dispensing head, the lower end 611 advantageously comes to the end of the race in abutment against the abutment wall 2060. This abutment thus defines a position of maximum compression of said head. According to an advantageous embodiment, the lateral crown 61 has an external diameter similar to the external diameter of the lower part of the skirt 20. Thus, when the dispensing head 6 is mounted on the organ body 2, the crown 61 can come to be placed in the continuity of the external surface 200 of the lower part of the skirt 20 during the maximum insertion of said dispensing head. This therefore results in an aesthetic advantage. The dispensing member which has just been described is a pump: a valve can also be envisaged in the context of the invention. The dispensing member is then mounted on the reservoir 1 by cooperation of the fixing means with the neck 13 of the reservoir. This assembly can be split into two steps: a step of prepositioning the dispensing member shown in Figures 1 and 2 and a step of final positioning of the dispensing member illustrated in Figures 3 and 4. During the prepositioning of the distribution member, the guide section 2011 of the skirt 20 first of all engages around the neck 13. This cooperation of the guide section 2011 with the external surface 131 of the neck thus takes place before the profile of attachment 2010 is in engagement with the collar 13. Indeed, the attachment profile 2010 during this step positioned above the edge 130. This prepositioning thus provides for the cooperation of two advantageously cylindrical surfaces, thus guaranteeing a stable and straight prepositioning of the dispensing member with respect to the reservoir 1. In addition, during this step, the external slope 210 of the sleeve d seal 21 comes almost in leaktight contact against the internal wall 133 of the neck 13. This leaktight contact therefore guarantees during this prepositioning step a seal at the neck of the reservoir. Then, the passage from the step of prepositioning the dispensing member to the step of definitive positioning of said dispensing member takes place by the exercise of axial pressure. This axial pressure exerted on the dispensing head 6 results in a sliding of the internal surface 201 of the skirt along the external wall 131 of the neck 13. The attachment profile 2010 then comes to bear against the external wall 131 for finally snap into the housing 133 of the neck. This housing advantageously prohibits any possibility of withdrawal of the dispensing member by axial traction. Indeed, the attachment profile 2011 is advantageously trapped in the housing 133. Therefore, the member 2 can thus be fixedly held on the neck 13. According to an advantageous embodiment, the bearing wall 2061 of the skirt 20 comes rest on the upper edge 130 of the neck during this final positioning. In addition, the free end 202 can abut against the shoulder
12 du réservoir et faire en sorte que la jupe 20 se situe dans le prolongement direct du corps 10 du réservoir. La douille d'étanchéité 21 quant à elle pénètre de plus en plus profondément dans le col 13 tout en restant en contact étanche avec le col 13 tout au long du déplacement effectué. Le positionnement définitif de l'organe de distribution est alors obtenu lorsque la paroi d'appui 2061 vient en butée contre le bord supérieur 130 et/ ou lorsque rextrémité libre 202 vient en butée contre l'épaulement 12 du réservoir. Selon un mode de réalisation particulièrement avantageux, une fois l'organe de distribution définitivement monté, l'entrée 230 du corps de chambre, voire le corps de chambre lui-même, peut être situé à un niveau axial situé sur la hauteur de la jupe et de préférence à un niveau situé au-dessus de la paroi d'appui 2061 de la jupe 20. Il est à noter que l'entrée 230 peut même être localisée à une hauteur axiale située au-delà de rextrémité supérieure 205 de la jupe 20. Ainsi, ces modes de réalisation peuvent faire en sorte que seuls le tube- plongeur 24 et la douille d'étanchéité 21 s'étendent dans le col 13. L'entrée 230, voire le corps de chambre, seront donc avantageusement masqués par la tête de distribution 6 et notamment par la couronne latérale 61. La présente invention permet donc d'obtenir lors de l'assemblage d'un organe de distribution sur le col d'un réservoir un pré-positionnement droit et stable dudit organe de distribution. Ainsi, le positionnement définitif de l'organe de distribution est facilité et est réalisé sans risque de casse ou d'apparition de problèmes d'étanchéité. Bien que la présente invention ait été décrite en référence à un mode de réalisation particulier de celle-ci, il est entendu qu'elle n'est pas limitée par ce mode de réalisation. Au contraire, un homme du métier, peut y apporter toutes modifications utiles sans sortir du cadre de la présente invention tel que défini par les revendications annexées. 12 of the tank and ensure that the skirt 20 is located in direct extension of the body 10 of the tank. The sealing sleeve 21 for its part penetrates more and more deeply into the neck 13 while remaining in sealed contact with the neck 13 throughout the movement carried out. The final positioning of the dispensing member is then obtained when the support wall 2061 abuts against the upper edge 130 and / or when the free end 202 abuts against the shoulder 12 of the reservoir. According to a particularly advantageous embodiment, once the dispensing member is definitively mounted, the inlet 230 of the chamber body, or even the chamber body itself, can be located at an axial level situated on the height of the skirt and preferably at a level above the wall support 2061 of the skirt 20. It should be noted that the inlet 230 can even be located at an axial height situated beyond the upper end 205 of the skirt 20. Thus, these embodiments can ensure that only the dip tube 24 and the sealing sleeve 21 extend in the neck 13. The inlet 230, or even the chamber body, will therefore advantageously be masked by the dispensing head 6 and in particular by the lateral crown 61. The present invention therefore makes it possible to obtain, during the assembly of a dispensing member on the neck of a reservoir, a straight and stable pre-positioning of said dispensing member. Thus, the final positioning of the dispensing member is facilitated and is carried out without risk of breakage or the appearance of sealing problems. Although the present invention has been described with reference to a particular embodiment thereof, it is understood that it is not limited by this embodiment. On the contrary, a person skilled in the art can make any useful modifications to it without departing from the scope of the present invention as defined by the appended claims.
