Description

Dispositif de distribution de produit fluide Fluid product dispensing device
La présente invention concerne un dispositif de distribution de produit fluide.The present invention relates to a device for dispensing a fluid product.
Plus particulièrement, l'invention concerne un tel dispositif comportant un réservoir, un organe de distribution pour distribuer sélectivement le produit contenu dans le réservoir, le volume de produit distribué à chaque actionnement étant compensé par de l'air d'éventation, le dispositif comprenant un filtre pour l'air d'éventation pour éviter toute contamination du produit contenu dans le réservoir. Généralement, les organes de distribution, tels que les pompes ou les valves, sont fixés au réservoir par l'intermédiaire d'une bague de fixation externe qui vient soit se sertir, soit s'encliqueter, soit se visser sur l'extérieur du col du réservoir. Ceci fonctionne de manière satisfaisante, mais peut impliquer un certain nombre d'inconvénients. Ainsi, le sertissage et le vissage impliquent l'utilisation de machines de montage relativement complexes, alors que l'encliquetage nécessite généralement des moyens pour empêcher la bague encliquetée de s'ouvrir après fixation. D'autre part, l'utilisation d'une bague externe peut impliquer une augmentation des dimensions externes du dispositif, et n'est pas toujours esthétiquement satisfaisante, de sorte qu'elle implique parfois l'utilisation d'un habillage externe supplémentaire. De plus, l'utilisation d'une bague de fixation externe ne permet pas de manière simple de réaliser des moyens de rétention de la tête de distribution, c'est à dire des moyens empêchant l'enlèvement de ladite tête, ceci étant particulièrement vrai pour les bagues à sertir qui sont généralement métalliques. Un autre aspect essentiel de la présente invention concerne le filtre pour l'éventation d'air. En effet, dans certains domaines, comme les domaines de la pharmacie, il est très important que le produit contenu dans le réservoir ne soit contaminé d'aucune manière, et en particulier par l'air d'éventation qui vient pénétrer à l'intérieur du réservoir après chaque actionnement de la pompe ou de la valve. De nombreux systèmes de fixation d'une pompe sur un réservoir ont été développés qui intègrent un tel filtre, ce système incorporant généralement une bague de fixation qui se fixe sur l'extérieur du col du réservoir comme expliqué ci-dessus.More particularly, the invention relates to such a device comprising a reservoir, a dispensing member for selectively distributing the product contained in the reservoir, the volume of product dispensed at each actuation being compensated by venting air, the device comprising a filter for the venting air to avoid any contamination of the product contained in the tank. Generally, the distribution members, such as the pumps or the valves, are fixed to the reservoir by means of an external fixing ring which comes either to be crimped, or to snap, or to be screwed on the outside of the neck. of the tank. This works satisfactorily, but can involve a number of drawbacks. Thus, crimping and screwing imply the use of relatively complex assembly machines, while the snap-fitting generally requires means to prevent the snapped-on ring from opening after fixing. On the other hand, the use of an external ring can imply an increase in the external dimensions of the device, and is not always aesthetically satisfactory, so that it sometimes involves the use of an additional external covering. In addition, the use of an external fixing ring does not make it possible in a simple manner to produce means for retaining the dispensing head, ie means preventing the removal of said head, this being particularly true for crimp rings which are generally metallic. Another essential aspect of the present invention relates to the filter for venting air. Indeed, in certain fields, like the fields of pharmacy, it is very important that the product contained in the tank is not contaminated in any way, and in particular by the air of venting which comes to penetrate inside of the tank after each actuation of the pump or valve. Many systems for fixing a pump to a tank have been developed which incorporate such a filter, this system generally incorporating a fixing ring which is fixed on the outside of the neck of the tank as explained above.
La présente invention a pour but de fournir un dispositif de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés.The object of the present invention is to provide a device for dispensing a fluid product which does not have the abovementioned drawbacks.
Plus particulièrement, la présente invention a pour but de fournir un dispositif de distribution de produit fluide dans lequel l'organe de distribution est fixé sur le col du réservoir sans utiliser de bague de fixation coopérant avec l'extérieur du col du réservoir. La présente invention a également pour but de fournir un tel dispositif de distribution de produit fluide qui assure une étanchéité parfaite, tout en garantissant un filtrage de l'air d'éventation après chaque actionnement du dispositif.More particularly, the object of the present invention is to provide a device for dispensing a fluid product in which the dispensing member is fixed to the neck of the tank without using a fixing ring cooperating with the outside of the neck of the tank. The present invention also aims to provide such a fluid dispensing device which ensures perfect sealing, while guaranteeing filtering of the vent air after each actuation of the device.
La présente invention a également pour but de fournir un dispositif de distribution de produit fluide qui soit simple et peu coûteux à fabriquer et à assembler.The present invention also aims to provide a fluid dispensing device which is simple and inexpensive to manufacture and assemble.
La présente invention a donc pour objet un dispositif de distribution de produit fluide comportant un réservoir de produit comprenant un col définissant une paroi interne, et une pompe fixée audit col du réservoir, le dispositif comportant une éventation d'air et un filtre pour l'air d'éventation, caractérisé en ce que ladite pompe comporte une partie de fixation qui est fixée sur la paroi interne dudit col du réservoir, ledit filtre étant fixé sur ladite partie de fixation.The present invention therefore relates to a fluid dispenser device comprising a reservoir of product comprising a neck defining an internal wall, and a pump fixed to said neck of the reservoir, the device comprising an air vent and a filter for the vent air, characterized in that said pump comprises a fixing part which is fixed on the internal wall of said neck of the tank, said filter being fixed on said fixing part.
Avantageusement, la pompe comporte un corps comprenant un bord supérieur qui forme ladite partie de fixation, de sorte que ledit corps est directement fixé sur la paroi interne du col du réservoir, ledit filtre étant disposé entre ledit bord supérieur du corps et ledit col du réservoir.Advantageously, the pump comprises a body comprising an upper edge which forms said fixing part, so that said body is directly fixed on the internal wall of the neck of the reservoir, said filter being disposed between said upper edge of the body and said neck of the reservoir. .
Avantageusement, le bord supérieur du corps est fixé, de préférence encliqueté, dans une bague formant partie de fixation, ladite bague étant fixée sur la paroi interne du col du réservoir, ledit filtre étant disposé entre ledit bord supérieur du corps et ladite bague. Avantageusement, la partie de fixation du corps est emmanchée à force dans le col du réservoir.Advantageously, the upper edge of the body is fixed, preferably latched, in a ring forming a fixing part, said ring being fixed on the internal wall of the neck of the reservoir, said filter being disposed between said upper edge of the body and said ring. Advantageously, the body fixing part is force-fitted into the neck of the tank.
Avantageusement, la partie de fixation du corps est encliquetée dans un profil de fixation prévu dans la paroi interne du col du réservoir. Avantageusement, ledit profil de fixation du col du réservoir comporte une rainure ou un épaulement d'encliquetage.Advantageously, the fixing part of the body is snapped into a fixing profile provided in the internal wall of the neck of the tank. Advantageously, said profile for fixing the neck of the reservoir comprises a groove or a latching shoulder.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante de trois modes de réalisation avantageux de celle-ci, faite en référence aux dessins joints, donnés à titre d'exemples non hmitatifs, et sur lesquels :Other characteristics and advantages of the present invention will appear more clearly during the following detailed description of three advantageous embodiments thereof, made with reference to the accompanying drawings, given by way of non-limiting examples, and in which :
- la figure 1 est une vue schématique en section transversale d'un premier mode de réalisation avantageux de la présente invention ;- Figure 1 is a schematic cross-sectional view of a first advantageous embodiment of the present invention;
- la figure 2 est une vue schématique en section transversale d'un second mode de réalisation avantageux de la présente invention ; et - la figure 3 est une vue schématique en section transversale d'un troisième mode de réalisation de la présente invention.- Figure 2 is a schematic cross-sectional view of a second advantageous embodiment of the present invention; and - Figure 3 is a schematic cross-sectional view of a third embodiment of the present invention.
En référence à la figure 1, il est représenté un réservoir 10 comportant un col 11 sur lequel est assemblé un organe de distribution 20, en l'occurrence une pompe. La pompe est actionnée au moyen d'une tête de distribution 50 qui incorpore l'orifice de distribution 51, et un capot de protection 60 peut être disposé autour de ladite tête de distribution lorsque la pompe n'est pas utilisée.Referring to Figure 1, there is shown a reservoir 10 having a neck 11 on which is assembled a dispensing member 20, in this case a pump. The pump is actuated by means of a dispensing head 50 which incorporates the dispensing orifice 51, and a protective cover 60 can be arranged around said dispensing head when the pump is not in use.
Selon l'invention, la pompe 20 comporte un corps de pompe 21 qui définit un bord supérieur 22. Le bord supérieur 22, dans l'exemple représenté sur la figure 1, est directement fixé sur la paroi interne 12 du col 11 du récipient 10. Dans cet exemple, la paroi interne 12 du col 11 du réservoir 10 incorpore une rainure 15 qui permet un encliquetage du bord supérieur 22 du corps 21 dans ledit col. Selon l'invention, un filtre 30 est disposé entre le bord supérieur 22 du corps 21 et le col 11 du réservoir 10. Avantageusement, ce filtre 30 agit également en tant que joint de col. Dans l'exemple représenté sur la figure 1, le col 11 comporte une bride radiale supérieure 18 qui maintient en place le filtre 30 entre ledit col 11 et le bord supérieur 22 du corps de pompe. Dans ce cas, la pompe est assemblée par l'extrémité inférieure du réservoir 10 (non représenté), mais il est entendu qu'un encliquetage du corps de pompe directement dans le col du réservoir est également envisageable par le col lui-même, c'est à dire par le côté supérieur sur la figure 1. Dans ce premier mode de réalisation représenté sur la figure 1, le bord supérieur 22 du corps agit donc directement en tant que partie de fixation de la pompe 20, et le filtre 30 est fixé sur ladite partie de fixation formée par ledit bord supérieur 22. Eventuellement, comme représenté sur la figure, une virole, qui sert à déterminer la position de repos de la pompe, peut être interposée entre le filtre et le bord supérieur 22 du corps de pompe 21.According to the invention, the pump 20 comprises a pump body 21 which defines an upper edge 22. The upper edge 22, in the example shown in FIG. 1, is directly fixed on the internal wall 12 of the neck 11 of the container 10 In this example, the internal wall 12 of the neck 11 of the reservoir 10 incorporates a groove 15 which allows the upper edge 22 of the body 21 to snap into said neck. According to the invention, a filter 30 is disposed between the upper edge 22 of the body 21 and the neck 11 of the reservoir 10. Advantageously, this filter 30 also acts as a neck seal. In the example shown in Figure 1, the neck 11 has an upper radial flange 18 which holds the filter 30 in place between said neck 11 and the upper edge 22 of the pump body. In this case pump is assembled by the lower end of the reservoir 10 (not shown), but it is understood that a snap-fastening of the pump body directly into the neck of the reservoir can also be envisaged by the neck itself, that is to say by the upper side in FIG. 1. In this first embodiment shown in FIG. 1, the upper edge 22 of the body therefore acts directly as the fixing part of the pump 20, and the filter 30 is fixed on said part of fixing formed by said upper edge 22. Optionally, as shown in the figure, a ferrule, which serves to determine the rest position of the pump, can be interposed between the filter and the upper edge 22 of the pump body 21.
En référence à la figure 2, il est représenté une variante de réalisation. Dans cette variante, le bord supérieur 22 du corps de pompe est fixé, notamment encliqueté dans une bague 25, qui agit en tant que partie de fixation de la pompe 20. C'est donc cette bague 25 qui est fixée sur la paroi interne 12 du col 11 du réservoir 10. Selon l'invention, le filtre 30 est disposé entre le bord supérieur 22 du corps de pompe 21 et ladite bague de fixation 25, éventuellement avec interposition d'une virole. La fixation de la bague 25 dans la paroi interne 12 du col 11 du réservoir 10 peut être réalisée soit par emmanchement à force, soit par encliquetage, comme représenté sur les figures 2 et 3. La figure 2 montre une première variante de réalisation de cet encliquetage de la bague 25 dans le col du réservoir, où la paroi interne 12 du col 11 incorpore une rainure périphérique 15 dans laquelle vient s'encliqueter une nervure correspondante de la bague 25. Dans l'exemple de la figure 3, la paroi interne 12 du col 11 incorpore un épaulement 15 qui permet l'enchquetage de ladite bague de fixation 25. Dans tous les cas, l'organe de distribution, en l'occurrence la pompe, est fixée directement sur la paroi interne 12 du col 11 du réservoir 10. De même, le filtre 30 pour l'air d'éventation est toujours disposé au niveau de ladite partie de fixation, qui dans le premier mode de réalisation est formée par le bord supérieur 22 du corps de pompe, et dans les deuxième et troisième modes de réalisation est formée par la bague 25. Ceci garantit une fixation sûre, sans avoir besoin d'utiliser une bague externe avec les inconvénients qu'elle implique, et assure une étanchéité et une filtration parfaite à chaque actionnement de la pompe de parla position du filtre 30, qui agit également avantageusement en tant que joint.Referring to Figure 2, there is shown an alternative embodiment. In this variant, the upper edge 22 of the pump body is fixed, in particular snapped into a ring 25, which acts as a fixing part of the pump 20. It is therefore this ring 25 which is fixed on the internal wall 12 of the neck 11 of the reservoir 10. According to the invention, the filter 30 is disposed between the upper edge 22 of the pump body 21 and said fixing ring 25, possibly with the interposition of a ferrule. The fixing of the ring 25 in the internal wall 12 of the neck 11 of the reservoir 10 can be carried out either by press fitting, or by snap-fastening, as shown in FIGS. 2 and 3. FIG. 2 shows a first alternative embodiment of this snap ring 25 into the neck of the tank, where the inner wall 12 of the neck 11 incorporates a peripheral groove 15 into which is snapped a corresponding rib of the ring 25. In the example of Figure 3, the inner wall 12 of the neck 11 incorporates a shoulder 15 which enables the said fixing ring 25 to be encased. In all cases, the dispensing member, in this case the pump, is fixed directly to the internal wall 12 of the neck 11 of the tank 10. Likewise, the filter 30 for the venting air is always disposed at the level of said fixing part, which in the first embodiment is formed by the upper edge 22 of the pump body, and in the second and three th embodiment is formed by the ring 25. This guarantees a secure fixing, without the need to use an external ring with the drawbacks which it implies, and ensures a perfect seal and filtration on each actuation of the pump by the position of the filter 30, which also advantageously acts as a seal.
Eventuellement, si nécessaire, comme représenté sur la figure 2, le dispositif peut en outre comporter un moyen d' étanchéité 70, appelé chaussette, qui fait l'étanchéité pour le produit entre le col et le corps de pompe, tout en permettant à l'air d'éventation de pénétrer à l'intérieur du réservoir, évidemment après être passé à travers ledit filtre 30.Optionally, if necessary, as shown in FIG. 2, the device can also comprise a sealing means 70, called a sock, which seals the product between the neck and the pump body, while allowing the vent air to penetrate inside the tank, obviously after passing through said filter 30.
Bien que la présente invention ait été décrite en référence à trois modes de réalisation avantageux de celle-ci, elle n'est pas limitée par les exemples représentés, et l'homme de l'art pourrait y apporter toutes modifications sans sortir du cadre de la présente invention telle que définie dans les revendications annexées. Although the present invention has been described with reference to three advantageous embodiments thereof, it is not limited by the examples shown, and those skilled in the art could make any modifications without departing from the scope of the present invention as defined in the appended claims.
