Description

Dispositif et procédé de fixation d'un organe de dosage dans un récipient contenant du produit à distribuer. Device and method for fixing a metering member in a container containing product to be dispensed.
La présente invention concerne un dispositif ou un procédé de fixation d'un organe de dosage, en particulier d'une pompe, à l'intérieur d'un récipient contenant un produit à distribuer, et s'applique plus particulièrement aux distributeurs à faibles doses, utilisés dans le domaine des parfums, des cosmétiques ou des produits pharmaceutiques .The present invention relates to a device or method for fixing a metering member, in particular a pump, inside a container containing a product to be dispensed, and applies more particularly to dispensers at low doses. , used in the field of perfumes, cosmetics or pharmaceutical products.
Il est connu dans l'état de la technique d'utiliser une bague pour monter un corps de pompe sur un récipient. Ce système présente certains inconvénients et nécessite notamment une opération de montage relativement coûteuse compte tenu de la nature des récipients (échantillons) .It is known in the prior art to use a ring to mount a pump body on a container. This system has certain drawbacks and in particular requires a relatively expensive assembly operation taking into account the nature of the containers (samples).
Un autre système connu, divulgué par le document EP-0 453 357, évite cet inconvénient en prévoyant un corps de pompe dimensionné de sorte à pouvoir être emmanché à force dans le récipient. La bague devient dans ce cas inutile. Pour assurer une mise en place correcte de la pompe, le corps de celle-ci comporte une partie inférieure dont le diamètre extérieur est réduit par rapport au diamètre du col du récipient. Le serrage s'opère au niveau du col par emmanchement à force de la partie supérieure du corps de pompe qui doit avoir un diamètre extérieur légèrement supérieur au diamètre dudit col. Ce dispositif présente également des inconvénients. Ainsi, le serrage étant assuré par le corps de pompe lui-même, les dimensions de celui-ci et notamment son diamètre extérieur, doivent être d'une précision très importante, ce qui occasionne un surcoût de fabrication. D'autre part, les diamètres des cols des récipients, notamment ceux réalisés en verre, peuvent varier légèrement de par leur fabrication ce qui peut empêcher une fixation correcte du corps de pompe dans ledit col du récipient. En outre, un emmanchement à force du corps de pompe lui-même peut dans certains cas provoquer un resserrement dudit corps de pompe et ainsi occasionner des frottements à l'intérieur de la pompe qui peuvent altérer son fonctionnement.Another known system, disclosed in document EP-0 453 357, avoids this drawback by providing a pump body dimensioned so that it can be force-fitted into the container. In this case, the ring becomes useless. To ensure correct positioning of the pump, the body thereof has a lower part whose outside diameter is reduced compared to the diameter of the neck of the container. Tightening takes place at the neck by force fitting the upper part of the pump body which must have an outside diameter slightly greater than the diameter of said neck. This device also has drawbacks. Thus, the tightening being ensured by the pump body itself, the dimensions of the latter and in particular its outside diameter, must be of very high precision, which causes an additional manufacturing cost. On the other hand, the diameters of the necks of the containers, in particular those made of glass, may vary slightly due to their manufacture, which may prevent correct fixing of the pump body in said neck of the container. In addition, a press fit of the pump body itself can in certain cases cause a tightening of said pump body and thus cause friction inside the pump which can impair its operation.
Un autre dispositif, divulgué par le document DE-31 22 982, prévoit un encliquetage du corps de pompe sur un bourrelet du col du récipient. Ce dispositif présente l'inconvénient de nécessiter des cols de récipient particuliers et de ne pas être adaptable sur un col standard.Another device, disclosed in document DE-31 22 982, provides for a snap-fastening of the pump body on a bead of the neck of the container. This device has the drawback of requiring special container necks and of not being adaptable to a standard neck.
La présente invention a pour but d'éviter les inconvénients précités en fournissant un dispositif de fixation simple et peu coûteux permettant de fixer le corps d'un organe de dosage, tel qu'une pompe, dans le col d'un récipient, tout en compensant les tolérances de dimensions dudit col de récipient. Le dispositif de l'invention s'adapte donc sur n'importe quel col de récipient, standard ou non, dont les dimensions peuvent varier légèrement lors de sa fabrication.The present invention aims to avoid the aforementioned drawbacks by providing a simple and inexpensive fixing device for fixing the body of a metering member, such as a pump, in the neck of a container, while compensating for the dimensional tolerances of said container neck. The device of the invention therefore adapts to any container neck, standard or not, the dimensions of which may vary slightly during its manufacture.
La présente invention a donc pour objet un dispositif de fixation d'un organe de dosage, tel qu'une pompe, comportant un corps, dans un col d'un récipient contenant un produit à distribuer, ledit corps de l'organe de dosage comportant une partie de plus petit diamètre et une partie de plus grand diamètre, le diamètre extérieur maximal dudit corps étant inférieur au diamètre intérieur dudit col, un logement étant formé dans ledit col du récipient, ledit logement étant adapté à recevoir un organe déformable qui, à l'état monté du dispositif de fixation, est déformé et/ou comprimé de telle sorte qu'il exerce une force radiale sur ledit col et sur ledit corps, ladite force assurant le fixation étanche de l'organe de dosage dans le col du récipient, ledit organe déformable venant s'adapter, avant montage, sur ladite partie de plus petit diamètre et étant déformé et/ou comprimé dans le logement, lors du montage, par ladite partie de plus grand diamètre du corps de 1 ' organe de dosage .The present invention therefore relates to a device for fixing a metering member, such as a pump, comprising a body, in a neck of a container containing a product to be dispensed, said body of the metering member comprising a portion of smaller diameter and a portion of larger diameter, the maximum outside diameter of said body being less than the inside diameter of said neck, a housing being formed in said neck of the container, said housing being adapted to receive a deformable member which, at the mounted state of the fixing device, is deformed and / or compressed so that it exerts a radial force on said neck and on said body, said force ensuring the tight fixing of the metering member in the neck of the container , said deformable member being adapted, before mounting, on said portion of smaller diameter and being deformed and / or compressed in the housing, during assembly, by said portion of larger diameter of the body of one metering member.
Cette mise en oeuvre permet un assemblage très facile. En effet, la mise en place de l'organe déformable sur la partie de plus petit diamètre se fait très aisément puisque l'organe déformable n'est soumis à aucune contrainte. Ensuite, la déformation de l'organe déformable est réalisée uniquement sur la partie de plus grand diamètre et non pas sur toute la hauteur du corps de pompe lors de son emmanchement dans le col du récipient. Le montage est donc plus aisé et plus fiable. En particulier, cette déformation et/ou compression est obtenue en appliquant une force verticale sur le corps de l'organe de dosage, cette force étant transmise à l'organe déformable.This implementation allows very easy assembly. Indeed, the establishment of the deformable member on the part of smaller diameter is very easily since the deformable member is not subject to any stress. Then, the deformation of the deformable member is carried out only on the part of larger diameter and not over the entire height of the pump body during its fitting in the neck of the container. Assembly is therefore easier and more reliable. In particular, this deformation and / or compression is obtained by applying a vertical force to the body of the metering member, this force being transmitted to the deformable member.
Avantageusement, lesdites parties de différents diamètres du corps de l'organe de dosage sont reliées par une partie conique de sorte que la déformation et/ou la compression de l'organe déformable est réalisée de manière progressive lors du montage.Advantageously, said parts of different diameters of the body of the metering member are connected by a conical part so that the deformation and / or compression of the deformable member is achieved progressively during assembly.
Avantageusement, le logement a une forme en section transversale environ carrée ou rectangulaire.Advantageously, the housing has a cross-sectional shape that is approximately square or rectangular.
Avantageusement, ledit organe déformable possède, avant le montage du dispositif de fixation, une forme différente de celle du logement, le montage du dispositif de fixation forçant par déformation et/ou compression ledit organe déformable à se conformer environ à la forme dudit logement, de sorte que ledit organe déformable exerce des forces sur les parois dudit logement. Selon un autre aspect, l'invention a aussi pour objet un procédé de fixation d'un organe de dosage, tel qu'une pompe, comportant un corps de pompe ayant une partie supérieure de plus grand diamètre et une partie inférieure de plus petit diamètre, dans un col d'un récipient contenant un produit à distribuer, ledit col comportant un logement annulaire, comprenant les étapes de : disposer un organe déformable sur ladite partie de plus petit diamètre du corps de l'organe de dosage ; - disposer l'organe de dosage sur le col du récipient, ledit organe déformable étant reçu dans ledit logement du col ; et emmancher à force le corps de l'organe de dosage dans le col du récipient de telle sorte que l'organe déformable est déformé et/ou comprimé dans le logement par ladite partie de plus grand diamètre du corps de l'organe de dosage, assurant ainsi la fixation étanche dudit organe de dosage dans le col du récipient.Advantageously, said deformable member has, before mounting the fixing device, a shape different from that of the housing, the mounting of the fixing device forcing by deformation and / or compression said deformable member to conform approximately to the shape of said housing, so that said deformable member exerts forces on the walls of said housing. According to another aspect, the invention also relates to a method for fixing a metering member, such as a pump, comprising a pump body having an upper part of larger diameter and a lower part of smaller diameter , in a container neck containing a product to be dispensed, said neck comprising an annular housing, comprising the steps of: placing a deformable member on said portion of smaller diameter of the body of the metering member; - Arrange the metering member on the neck of the container, said deformable member being received in said housing of the neck; and press fit the body of the metering member into the neck of the container so that the deformable member is deformed and / or compressed in the housing by said portion of larger diameter of the body of the metering member, thus ensuring the tight fixing of said metering member in the neck of the container.
D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description suivante d'un mode de réalisation de l'invention, donné à titre d'exemple non limitatif, en regard des dessins joints, sur lesquels : la figure 1 représente une vue schématique en coupe verticale du dispositif de fixation selon un mode de réalisation avantageux de l'invention, avant montage, et la figure 2 représente une vue schématique en coupe verticale du dispositif de la figure 1, après montage. En référence aux dessins, l'ensemble doseur de l'invention comporte un récipient 1 ayant un col cylindrique 2 et contenant un produit à distribuer. Le récipient peut être de forme quelconque et réalisé en matière quelconque, généralement du verre ou une matière plastique. Pour assurer la distribution du produit contenu dans le récipient, un organe de dosage 10 est prévu, ledit organe de dosage 10 comportant un corps 11.Other characteristics and advantages of the present invention will appear during the following description of an embodiment of the invention, given by way of nonlimiting example, with reference to the accompanying drawings, in which: FIG. 1 represents a schematic view in vertical section of the fixing device according to an advantageous embodiment of the invention, before assembly, and FIG. 2 represents a schematic view in vertical section of the device of FIG. 1, after assembly. With reference to the drawings, the metering assembly of the invention comprises a container 1 having a cylindrical neck 2 and containing a product to be dispensed. The container can be of any shape and made of any material, generally glass or plastic. To ensure the distribution of the product contained in the container, a metering member 10 is provided, said metering member 10 comprising a body 11.
Avantageusement, ledit organe de dosage 10 est une pompe permettant une distribution sélective du produit, et la suite de la description sera faite en référence à une pompe. Selon la présente invention, le diamètre extérieur dudit corps de pompe est inférieur au diamètre intérieur dudit col cylindrique 2 du récipient 1.Advantageously, said metering member 10 is a pump allowing a selective distribution of the product, and the following description will be made with reference to a pump. According to the present invention, the outside diameter of said pump body is less than the inside diameter of said cylindrical neck 2 of container 1.
Selon l'invention, pour fixer ledit corps de pompe 11 dans ledit col du récipient 2, il est prévu dans le col 2, un logement 20 destiné à recevoir un organe déformable 30 qui est de préférence souple et élastique. De préférence, ledit organe déformable 30 est annulaire et est destiné à s'adapter au logement 10 également annulaire qui s'étend circonférentiellement autour du col 2, de sorte qu'à l'état monté du dispositif de fixation, ledit organe déformable 30 assure à la fois la fixation de la pompe dans le col et l'étanchéité au niveau dudit col. En effet, l'organe déformable élastique 30 peut avoir, avant le montage du dispositif de fixation, une forme différente de celle du logement 30 et lors du montage du dispositif de fixation, ledit organe déformable 30 est forcé par compression à se conformer environ à la forme dudit logement 30. La fixation du corps de pompe dans le col du récipient est donc assuré par la compression dudit organe déformable 30 à l'intérieur dudit logement 20, ledit organe déformable 30 étant en contact simultanément avec ledit col du récipient et avec ledit corps de pompe . En référence aux figures 1 et 2 , il est représenté un mode de réalisation avantageux de l'invention. Dans ce mode de réalisation, le logement 20 est réalisé dans le col 2 du récipient 1, de préférence à son extrémité supérieure. L'organe déformable 30 peut, avant montage, être disposé dans le logement 20, mais de préférence, il est disposé sur le corps de pompe 11.According to the invention, to fix said pump body 11 in said neck of the container 2, there is provided in the neck 2, a housing 20 intended to receive a deformable member 30 which is preferably flexible and elastic. Preferably, said deformable member 30 is annular and is intended to adapt to the housing 10 also annular which extends circumferentially around the neck 2, so that in the assembled state of the fixing device, said deformable member 30 ensures both the fixing of the pump in the neck and the seal at said neck. Indeed, the elastic deformable member 30 may have, before the mounting of the fixing device, a shape different from that of the housing 30 and during mounting of the fixing device, said deformable member 30 is forced by compression to conform approximately to the shape of said housing 30. The fixing of the pump body in the neck of the container is therefore ensured by the compression of said deformable member 30 inside said housing 20, said deformable member 30 being in simultaneous contact with said neck of the container and with said pump body. Referring to Figures 1 and 2, there is shown an advantageous embodiment of the invention. In this embodiment, the housing 20 is produced in the neck 2 of the container 1, preferably at its upper end. The deformable member 30 can, before mounting, be placed in the housing 20, but preferably it is placed on the pump body 11.
Comme représenté sur les figures 1 et 2 , le corps de pompe 11 comporte une partie inférieure lia de plus petit diamètre et une partie supérieure 11b de plus grand diamètre. Avant montage, l'organe déformable 30 s'adapte sur la partie lia de plus petit diamètre et au début de l'emmanchement du corps de pompe 11 dans le col, il vient d'abord s'adapter dans le logement 20 du col. Ensuite, l'organe déformable 30 est comprimé et/ou déformé par la partie 11b de plus grand diamètre, créant ainsi la force radiale sur le col 2 et le corps de pompe 11 qui assure la fixation étanche de ces deux éléments. Avantageusement, la pompe 10 comporte un trou d ' évent 50 qui peut être prévu dans la partie de plus grand diamètre 11b du corps de pompe 11, à condition de se situer à l'état monté du dispositif en-dessous de l'organe déformable 30 assurant la fixation étanche de la pompe sur le récipient.As shown in Figures 1 and 2, the pump body 11 has a lower portion 11a of smaller diameter and an upper portion 11b of larger diameter. Before mounting, the deformable member 30 adapts on the part 11a of smaller diameter and at the start of the fitting of the pump body 11 into the neck, it first fits into the housing 20 of the neck. Then, the deformable member 30 is compressed and / or deformed by the part 11b of larger diameter, thus creating the radial force on the neck 2 and the pump body 11 which ensures the tight fixing of these two elements. Advantageously, the pump 10 includes a vent hole 50 which can be provided in the larger diameter portion 11b of the pump body 11, provided that it is in the assembled state of the device below the deformable member. 30 ensuring the tight fixing of the pump on the container.
De préférence, les deux parties lia et 11b du corps de pompe 11 sont reliées entre elles par une partie conique, de sorte que la déformation et/ou la compression de l'organe déformable 30 se fait progressivement lors du montage, facilitant celui-ci.Preferably, the two parts 11a and 11b of the pump body 11 are connected to each other by a conical part, so that the deformation and / or compression of the deformable member 30 takes place gradually during assembly, facilitating the latter .
Avantageusement, le logement 20 a une forme en section transversale environ carrée ou rectangulaire, de même que l'organe déformable 30. Bien entendu, les dimensions du logement et de l'organe déformable ne correspondent pas exactement, afin d'engendrer la déformation et/ou la compression de l'organe déformable 30 dans le logement 20.Advantageously, the housing 20 has a shape in approximately square or rectangular cross section, as does the deformable member 30. Of course, the dimensions of the housing and of the deformable member do not exactly correspond, in order to generate the deformation and / or the compression of the deformable member 30 in the housing 20.
De même, toute autre section verticale de l'organe déformable est imaginable à condition qu'elle ne corresponde pas exactement en forme et en dimension, à la section verticale du logement 20, qui peut également être quelconque. Ainsi, lors de l'emmanchement, l'organe déformable 30 est forcé à se conformer environ à la forme dudit logement 20, exerçant ainsi les forces radiales sur le col et le corps de pompe pour assurer la fixation et 1 ' étanchéité. Similarly, any other vertical section of the deformable member is conceivable provided that it does not correspond exactly in shape and in size, to the vertical section of the housing 20, which can also be arbitrary. Thus, during fitting, the deformable member 30 is forced to conform approximately to the shape of said housing 20, thus exerting the radial forces on the neck and the pump body to ensure fixing and sealing.
