Les dispositifs de distribution de produit fluide sont bien connus dans l'état de la technique. Ils sont utilisés notamment pour distribuer des produits fluides, par exemple liquides, pâteux, gazeux ou pulvérulents, à partir d'un réservoir au moyen d'un organe de distribution tel qu'une pompe ou une valve. Cet organe de distribution est généralement fixé sur le réservoir au moyen d'un élément de fixation, par exemple une bague à encliqueter ou similaire. Pour assurer l'étanchéité de cette fixation, un joint de col est généralement disposé entre le bord supérieur du col du réservoir et l'élément de fixation, ce joint de col étant généralement réalisé en matériau élastomère pour assurer cette étanchéité. Pour assurer une bonne étanchéité, le joint ne doit être ni trop comprimé, ni trop peu, et en particulier dans le cadre d'une bague de fixation encliquetable, il peut se poser des problèmes d'étanchéité, par exemple en raisons des tolérances de fabrication, c'est-à-dire des variations dimensionnelles et/ou géométriques des différentes pièces constitutives du dispositif, et notamment du col du réservoir. De plus, l'utilisation d'une bague encliquetable et d'un joint de col classique ne permet pas d'adapter le dispositif à différentes configurations ou topographies de col de réservoir, et implique par conséquent de réaliser un dispositif spécifique pour chaque type de col de réservoir.Fluid dispensing devices are well known in the state of the art. They are used in particular for dispensing fluid products, for example liquid, pasty, gaseous or powdery, from a reservoir by means of a dispensing member such as a pump or a valve. This dispenser member is generally attached to the reservoir by means of a fastener, for example a snap ring or the like. To ensure the seal of this fastener, a neck gasket is generally disposed between the upper edge of the neck of the tank and the fixing element, this neck gasket being generally made of elastomeric material to ensure this seal. To ensure a good seal, the seal must not be too compressed or too little, and in particular in the context of a snap-fastening ring, there may be sealing problems, for example because of the tolerances of the seal. manufacture, that is to say, dimensional and / or geometric variations of the various component parts of the device, and in particular the neck of the reservoir. In addition, the use of a snap ring and a conventional neck seal does not allow the device to be adapted to different configurations or topographies of tank neck, and therefore involves making a specific device for each type of neck. tank collar.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante faite en référence aux dessins joints, donnés à titre d'exemples non limitatifs, et sur lesquels :

  • la figure 1 est une vue schématique en section transversale d'une partie d'un dispositif de distribution de produit fluide, avant son assemblage sur un réservoir ;
  • la figure 2 est une vue similaire à celle de la figure 1, montrant une position assemblée sur un premier type de col de réservoir ; et
  • la figure 3 est une vue similaire à celle de la figure 2, montrant un assemblage sur un autre type de col de réservoir.
Other features and advantages of the present invention will appear more clearly in the following detailed description given with reference to the accompanying drawings, given by way of non-limiting examples, and in which:
  • the figure 1 is a schematic cross-sectional view of a portion of a fluid dispenser device prior to assembly on a reservoir;
  • the figure 2 is a view similar to that of the figure 1 showing an assembled position on a first type of tank neck; and
  • the figure 3 is a view similar to that of the figure 2 , showing an assembly on another type of tank neck.

En référence aux figures, le dispositif de distribution de produit fluide de l'invention comporte un organe de distribution 10, qui dans l'exemple représenté est une pompe 10, mais qui pourrait bien entendu être également réalisé sous la forme d'une valve. La pompe 10 comporte un corps de pompe 11 dans lequel coulisse une tige d'actionnement 12 solidaire d'un piston 13, mais il est entendu que la structure et le fonctionnement de la pompe pourraient être quelconques, cette structure et ce fonctionnement n'intervenant pas directement dans la présente invention. La pompe ne sera donc pas plus amplement décrite ci-après, et l'exemple représenté sur les dessins n'est donné qu'à titre illustratif mais non limitatif pour l'invention.With reference to the figures, the fluid dispenser device of the invention comprises a dispensing member 10, which in the example shown is a pump 10, but which could of course also be made in the form of a valve. The pump 10 comprises a pump body 11 in which slides an actuating rod 12 integral with a piston 13, but it is understood that the structure and operation of the pump could be any, this structure and operation not directly involved in the present invention. The pump will therefore not be more fully described below, and the example shown in the drawings is given for illustrative but not limiting for the invention.

De manière classique, il est prévu un élément de fixation 20 pour fixer la pompe 10 sur le réservoir 30, comme visible sur les figures 2 et 3. Cet élément de fixation 20 peut être réalisé sous la forme d'une bague encliquetable comportant des moyens de fixation 21 réalisés sous la forme d'un profil d'encliquetage destiné à s'encliqueter sur le col 35 du réservoir 30, comme cela est représenté sur les figures 2 et 3, qui montrent le dispositif en position assemblée. Ce profil d'encliquetage 21 peut être réalisé par une structure élastiquement déformable, mais tout autre structure d'encliquetage est envisageable, par exemple des pattes d'encliquetage. De même, l'élément de fixation 20 n'est pas nécessaire une bague encliquetable mais pourrait être réalisée de manière quelconque souhaitable, par exemple sous la forme d'une bague vissable, sertissable ou similaire.Conventionally, there is provided a fastening element 20 for fixing the pump 10 on the reservoir 30, as visible on the Figures 2 and 3 . This fastening element 20 can be made in the form of a snap-in ring comprising fastening means 21 made in the form of a detent profile intended to snap onto the neck 35 of the reservoir 30, as shown. on the Figures 2 and 3 , which show the device in assembled position. This snap-fitting profile 21 may be made by an elastically deformable structure, but any other snap-fastening structure may be envisaged, for example snap-fastening tabs. Similarly, the fastener 20 is not required a snap ring but could be carried out in any desired manner, for example in the form of a screwable ring, crimpable or the like.

Selon l'invention, une tourette 40 est interposée entre l'élément de fixation 20 et le corps de pompe 11. Cette tourette 40 peut notamment être encliquetée sur le bord supérieur du corps de pompe 11, l'élément de fixation 20 étant alors lui-même encliqueté sur ladite tourette, comme cela représenté sur les figures. D'autres moyens de fixation de la tourette 40 au corps de pompe 11 et de l'élément de fixation 20 à la tourette 40 sont bien entendus envisageables. La tourette comporte une bride radiale déformable 45 qui s'étend entre le bord supérieur du col 35 de réservoir 30 et une partie environ radiale de l'élément de fixation 20. Cette bride radiale 45 de la tourette 40 est destinée, après assemblage, à assurer l'étanchéité au niveau de la fixation sur le col 35 du réservoir. Elle remplace donc le joint de col habituel, et de préférence cette bride radiale est donc réalisée en un matériau approprié pour réaliser l'étanchéité, par exemple un matériau élastomère. Comme visible sur les figures, la bride radiale 45 comporte des moyens d'étanchéité déformables 46, 47 qui se projettent à partir de ladite bride radiale, et qui après assemblage coopèrent de manière étanche avec l'élément de fixation 20. Ainsi, la bride radiale 45 elle-même forme l'étanchéité avec le bord supérieur du col 35 du réservoir 30 et les moyens d'étanchéité déformables 46, 47 forment l'étanchéité avec l'élément de fixation 20.According to the invention, a turret 40 is interposed between the fixing element 20 and the pump body 11. This turret 40 can in particular be snapped onto the upper edge of the pump body 11, the fastening element 20 then being even snapped onto said turret, as shown in the figures. Other means of fixing the turret 40 to the pump body 11 and the fastening element 20 to the turret 40 are of course conceivable. The turret comprises a deformable radial flange 45 which extends between the upper edge of the tank neck 30 and an approximately radial portion of the fastening element 20. This radial flange 45 of the turret 40 is intended, after assembly, to seal at the level of the attachment on the neck 35 of the tank. It therefore replaces the usual neck seal, and preferably this radial flange is made of a material suitable for sealing, for example an elastomeric material. As shown in the figures, the radial flange 45 comprises deformable sealing means 46, 47 which project to from said radial flange, and which after assembly cooperate sealingly with the fixing element 20. Thus, the radial flange 45 itself forms the seal with the upper edge of the neck 35 of the tank 30 and the means of deformable sealing 46, 47 form the seal with the fastening element 20.

La bride radiale 45, avant assemblage, est recourbée vers le haut, comme cela est visible sur la figure 1. Cette structure particulière permet au dispositif de l'invention de pouvoir non seulement compenser des tolérances de fabrication des différents éléments constitutifs du dispositif, mais également de s'adapter à des configurations de col de réservoir différentes comme notamment visible sur es figures 2 et 3. En effet, la forme recourbée de la bride radiale 45 permet de s'adapter à des variations dimensionnelles lors de l'assemblage, cette compensation des variations dimensionnelles étant non seulement obtenues par le caractère déformable du matériau lui-même, mais surtout par la structure recourbée de la bride radiale 45. En se référant aux figures 2 et 3, on constate que sur la figure 2, le col 35 du réservoir a une dimension axiale inférieure au col représenté sur la figure 3. La position assemblée représentée sur la figure 2 montre une bride radiale 45 qui est aplatie entre le bord supérieur du col 35 et l'élément de fixation 20 en comparaison à la forme initiale représentée sur la figure 1, mais la bride radiale n'est pas complètement plane, ce qui montre qu'il reste de la marge dans l'exemple de la figure 2. Au contraire, dans l'exemple de la figure 3, dans lequel la dimension du col 35 est supérieure, l'encliquetage de l'élément de fixation 20 sur le col du réservoir provoque un aplatissement totale de la bride radiale 45, comme clairement représenté sur cette figure.The radial flange 45, before assembly, is curved upwards, as can be seen on the figure 1 . This particular structure allows the device of the invention to be able not only to compensate manufacturing tolerances of the various constituent elements of the device, but also to adapt to different tank neck configurations such as in particular visible on es Figures 2 and 3 . Indeed, the curved shape of the radial flange 45 makes it possible to adapt to dimensional variations during assembly, this compensation for dimensional variations being not only obtained by the deformable nature of the material itself, but above all by the structure curved radial flange 45. Referring to Figures 2 and 3 , we see that on the figure 2 , the neck 35 of the reservoir has an axial dimension less than the neck represented on the figure 3 . The assembled position represented on the figure 2 shows a radial flange 45 which is flattened between the upper edge of the neck 35 and the fastening element 20 in comparison with the initial shape shown in FIG. figure 1 but the radial flange is not completely flat, which shows that there is still some room left in the example of figure 2 . On the contrary, in the example of figure 3 , in which the dimension of the neck 35 is greater, the snap of the fastener 20 on the neck of the tank causes a total flattening of the radial flange 45, as clearly shown in this figure.

Les moyens d'étanchéité déformables 46, 47 sont de préférence réalisés sous la forme de deux projections qui, dans la position avant assemblage, s'étendent avantageusement axialement et parallèlement l'une à l'autre. L'élément de fixation 20 comporte avantageusement un profil environ conique 25 destiné à coopérer avec ces deux projections 46, 47 de la tourette 40. Comme visible sur les figures 2 et 3, ce profil environ conique 25 de l'élément de fixation 20 vient entre lesdites projections 46, 47 lors de l'assemblage et les écarte de sorte que ces deux projections 46, 47 vont former un angle l'une par rapport à l'autre en position assemblée. La pointe du cône du profil environ conique 25 est alors disposé entre ces deux projections et l'étanchéité est donc assurée des deux côtés de ladite pointe du cône. A nouveau, les figures 2 et 3 montrent que cette structure permet également de s'adapter à des dimensions d'encliquetage variables, le cône 25 de l'élément de fixation pénétrant plus ou moins entre les deux projections 46, 47, selon la dimension du col du réservoir.The deformable sealing means 46, 47 are preferably made in the form of two projections which, in the position before assembly, advantageously extend axially and parallel to one another. The fastening element 20 advantageously comprises an approximately conical profile intended to cooperate with these two projections 46, 47 of the turret 40. Figures 2 and 3 this approximately conical profile of the fastener 20 comes between said projections 46, 47 during assembly and spreads them so that these two projections 46, 47 will form an angle relative to each other in the assembled position. The tip of the cone of the approximately conical profile 25 is then arranged between these two projections and the seal is thus provided on both sides of said tip of the cone. Again, the Figures 2 and 3 show that this structure also allows to adapt to variable latching dimensions, the cone 25 of the fastener penetrating more or less between the two projections 46, 47, depending on the size of the neck of the tank.

Un avantage particulier de la présente invention est qu'il garantit une étanchéité même lorsque la bride radiale 45 n'est pas complètement aplatie entre l'élément de fixation et le bord supérieur du col du réservoir (c'est-à-dire dans la position de la figure 2, où on constate que la bride radiale est encore légèrement recourbée même après assemblage). En effet, la forme recourbée de la bride radiale 45 garantit au moins une zone d'étanchéité entre la bride radiale 45 et le bord supérieur du col du réservoir et au moins deux zones d'étanchéité, de préférence trois, entre ladite bride radiale et l'élément de fixation 20. Dans l'exemple représenté sur les dessins, et notamment sur la figure 2, la bride radiale 45 forme trois points d'étanchéité avec l'élément de fixation 20, à savoir les deux projections 46, 47 et l'extrémité radiale externe de la bride radiale 45 qui coopère également de manière étanche avec une partie de l'élément de fixation 20.A particular advantage of the present invention is that it ensures a seal even when the radial flange 45 is not completely flattened between the fastener and the upper edge of the neck of the reservoir (i.e. position of the figure 2 , where it is found that the radial flange is still slightly bent even after assembly). Indeed, the curved shape of the radial flange 45 ensures at least one sealing zone between the radial flange 45 and the upper edge of the neck of the reservoir and at least two sealing zones, preferably three, between said radial flange and in the example shown in the drawings, and in particular on the figure 2 , the radial flange 45 forms three sealing points with the fastening element 20, namely the two projections 46, 47 and the radial outer end of the radial flange 45 which also co-operates in leaktight manner with a part of the fastening element 20.

Avantageusement, la tourette 40 coopère également de manière étanche avec la tige d'actionnement 12 de la pompe de sorte que la tourette 40 assure un fonctionnement sure et fiable et étanche du dispositif de distribution dans son ensemble.Advantageously, the turret 40 also cooperates sealingly with the actuating rod 12 of the pump so that the turret 40 ensures safe and reliable operation and sealing of the dispensing device as a whole.

La présente invention permet donc de réaliser un dispositif de distribution qui permet de s'adapter à différentes formes et topographies de col de réservoir, ainsi qu'à compenser des tolérances de fabrication, ce qui évite d'avoir à modifier le dispositif tout en garantissant l'étanchéité dans toutes les situations. La présente invention permet donc de réaliser de manière simple et peu coûteuse un système polyvalent et transposable à différentes situations.The present invention therefore makes it possible to produce a dispensing device that makes it possible to adapt to different tank neck shapes and topographies, as well as to compensate for manufacturing tolerances, which avoids having to modify the device while guaranteeing waterproofness in all situations. The present invention thus makes it possible to realize in a simple and inexpensive manner a system that is versatile and transposable to different situations.

Bien que décrite en référence à un mode de réalisation particulier de l'invention, il est entendu que celle-ci n'est pas limitée aux exemples représentés ni décrits. Au contraire, un homme du métier pourrait y apporter toutes modifications utiles sans sortir du cadre de la présente invention tel que défini par les revendications annexées.Although described with reference to a particular embodiment of the invention, it is understood that it is not limited to the examples shown or described. On the contrary, a person skilled in the art could make any useful modifications without departing from the scope of the present invention as defined by the appended claims.
