Description

Valve de distribution de produit fluide et distributeur de produit fluide comprenant une telle valve Fluid product distribution valve and fluid product distributor comprising such a valve
La présente invention concerne une valve de distribution de produits fluides, ainsi qu'un distributeur de produit fluide comportant une telle valve. Plus particulièrement, la présente invention concerne une valve qui simplifie le remplissage du distributeur sur lequel la valve est assemblée. Les valves de distribution de produit fluide sont bien connues. Elles comportent généralement un corps de valve dans lequel coulisse une soupape entre une position de repos et une position de distribution, la soupape en position de distribution reliant le réservoir (dans le cas d'une valve continue) ou une chambre de dosage (dans le cas d'une valve doseuse) avec l'extérieur. Le produit fluide est distribué à travers la soupape au moyen d'un gaz propulseur.The present invention relates to a fluid dispenser valve, as well as a fluid dispenser comprising such a valve. More particularly, the present invention relates to a valve which simplifies the filling of the dispenser on which the valve is assembled. Fluid dispensing valves are well known. They generally include a valve body in which a valve slides between a rest position and a dispensing position, the valve in the dispensing position connecting the reservoir (in the case of a continuous valve) or a metering chamber (in the case of a metering valve) with the outside. The fluid is distributed through the valve by means of a propellant gas.
Le contenu du réservoir est donc sous pression, et le remplissage de ce réservoir avec le produit fluide et le propulseur pose un certain nombre de problèmes, notamment en exerçant sur les joints de la valves des contraintes importantes qui risquent de les endommager. La présente invention a pour but de fournir une valve de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés. La présente invention a notamment pour but de fournir une valve de distribution de produit fluide qui améliore le remplissage en évitant de traumatiser les joints fonctionnels de la valve pendant le remplissage. La présente invention a aussi pour but de fournir une valve de distribution de produit fluide qui simplifie le remplissage du distributeur sur lequel la valve est assemblée. La présente invention a notamment pour but de fournir une telle valve qui soit simple et peu coûteuse à fabriquer et à assembler. La présente invention a également pour but de fournir une valve doseuse de distribution de produit fluide telle que décrite ci-dessus, qui garantit une précision et une reproductibilité totale du dosage, en évitant notamment toute perte de doses entre deux actionnements, pendant les périodes de repos de la valve. La présente invention a donc également pour but de fournir une telle valve qui soit fiable d'utilisation, aussi bien pendant la phase de remphssage, que pendant la phase d'utilisation de la valve lors de la distribution du produit. La présente invention a donc pour objet une valve de distribution pour distributeur de produits fluides, comportant un corps de valve et une soupape coulissant dans ledit corps de valve entre une position de repos et une position de distribution, ladite soupape comportant une partie de remplissage déplaçable entre une position de remplissage, permettant le remplissage du distributeur à travers ladite soupape, et une position d'utilisation, dans laquelle ladite partie de remphssage est fixée de manière étanche à ladite soupape. Avantageusement, ladite partie de remplissage est fixée à ladite soupape par encliquetage. Avantageusement, ladite soupape comporte un canal central traversant, comportant une partie de canal conique, ladite partie de remplissage comportant une tête conique coopérant en position d'utilisation avec ladite partie de canal conique de ladite soupape pour l'obturer de manière étanche. Avantageusement, ladite partie de remplissage comporte un joint d'étanchéité pour assurer une fixation étanche de la partie de remplissage dans la soupape en position d'utilisation. Avantageusement, laquelle ladite valve est une valve doseuse comportant une chambre de dosage. Avantageusement, ladite chambre de dosage est fermée hermétiquement en position de repos de la soupape. Avantageusement, le corps de valve est réalisé en deux parties fixées l'une sur l'autre, notamment par encliquetage. La présente invention a également pour objet un distributeur de produit fluide comportant un réservoir contenant le produit fluide et comprenant une valve telle que décrite ci-dessus. Avantageusement, la valve est une valve doseuse comportant une chambre de dosage, ladite chambre de dosage étant isolée du réservoir en position de repos et en position de distribution de la soupape. D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante d'un mode de réalisation particulier de celle-ci, 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 valve de distribution selon un mode de réalisation avantageux de la présente invention, en position de remplissage, la figure 2 est une vue similaire à celle de la figure 1, montrant la partie de remplissage de la soupape en position d'utilisation, et la soupape en position de repos, et la figure 3 est une vue similaire à celle de la figure 2, montrant la soupape en position de distribution. En référence aux figures, qui représentent un mode de réalisation avantageux de la présente invention, la valve comporte un corps de valve 1 ainsi qu'une soupape 10 qui coulisse dans ledit corps de valve entre une position de repos (représentée sur la figure 2) et une position de distribution (représentée sur la figure 3). La valve représentée sur les dessins est une valve doseuse, c'est-à-dire qu'elle comporte une chambre de dosage 2 qui définit précisément la dose à distribuer à chaque actionnement de cette valve. Dans l'exemple représenté sur les dessins, le corps de valve 1 est réalisé en deux parties et comporte une partie haute la qui incorpore la chambre de dosage 2, et une partie basse lb qui est fixée, notamment encliquetée, sur ladite partie haute la. Cette mise en œuvre simplifie l'assemblage de la valve, comme cela sera décrit plus en détail ci-après.The contents of the reservoir are therefore under pressure, and the filling of this reservoir with the fluid product and the propellant poses a certain number of problems, in particular by exerting on the valve seals significant stresses which are liable to damage them. The object of the present invention is to provide a valve for dispensing a fluid product which does not have the abovementioned drawbacks. The object of the present invention is in particular to provide a valve for dispensing a fluid product which improves filling while avoiding trauma to the functional seals of the valve during filling. The present invention also aims to provide a fluid dispensing valve which simplifies the filling of the dispenser on which the valve is assembled. The present invention aims in particular to provide such a valve which is simple and inexpensive to manufacture and assemble. The present invention also aims to provide a metering valve for dispensing a fluid product as described above, which guarantees precision and total reproducibility of the dosage, in particular avoiding any loss of doses between two actuations, during periods of valve rest. The present invention therefore also aims to provide such a valve which is reliable to use, both during the filling phase, and during the use phase of the valve during the distribution of the product. The present invention therefore relates to a dispensing valve for a dispenser for fluid products, comprising a valve body and a valve sliding in said valve body between a rest position and a dispensing position, said valve comprising a movable filling part. between a filling position, allowing the filling of the dispenser through said valve, and a position of use, in which said filling portion is tightly fixed to said valve. Advantageously, said filling part is fixed to said valve by snap-fastening. Advantageously, said valve comprises a through central channel, comprising a conical channel part, said filling part comprising a conical head cooperating in the position of use with said conical channel part of said valve in order to close it sealingly. Advantageously, said filling part includes a seal to ensure a tight fixing of the filling part in the valve in the use position. Advantageously, which said valve is a metering valve comprising a metering chamber. Advantageously, said metering chamber is hermetically closed in the rest position of the valve. Advantageously, the valve body is made in two parts fixed to one another, in particular by snap-fastening. The present invention also relates to a fluid product dispenser comprising a reservoir containing the fluid product and comprising a valve as described above. Advantageously, the valve is a metering valve comprising a metering chamber, said metering chamber being isolated from the reservoir in the rest position and in the valve dispensing position. Other characteristics and advantages of the present invention will appear more clearly during the following detailed description of a particular embodiment thereof, given with reference to the accompanying drawings, given by way of nonlimiting examples, and on which, - Figure 1 is a schematic cross-sectional view of a dispensing valve according to an advantageous embodiment of the present invention, in the filling position, Figure 2 is a view similar to that of Figure 1, showing the filling part of the valve in the use position, and the valve in the rest position, and FIG. 3 is a view similar to that of FIG. 2, showing the valve in the dispensing position. With reference to the figures, which represent an advantageous embodiment of the present invention, the valve comprises a valve body 1 as well as a valve 10 which slides in said valve body between a rest position (represented in FIG. 2) and a dispensing position (shown in Figure 3). The valve shown in the drawings is a metering valve, that is to say that it comprises a metering chamber 2 which precisely defines the dose to be dispensed on each actuation of this valve. In the example shown in the drawings, the valve body 1 is made in two parts and has an upper part la which incorporates the metering chamber 2, and a lower part lb which is fixed, in particular snapped on, on said upper part la . This implementation simplifies the assembly of the valve, as will be described in more detail below.
La valve est assemblée sur un réservoir (non représenté) d'un distributeur de produit fluide, de préférence au moyen d'une capsule de fixation 40, qui peut être de tout type, et notamment encliquetable, vissable ou sertissable. Un joint de soupape 5 ainsi qu'un joint de col 6 sont généralement interposés entre ladite capsule de fixation 40 et respectivement le corps de valve 1 et le col du réservoirThe valve is assembled on a reservoir (not shown) of a fluid dispenser, preferably by means of a fixing capsule 40, which can be of any type, and in particular snap-on, screwable or crimpable. A valve seal 5 and a neck seal 6 are generally interposed between said fixing capsule 40 and respectively the valve body 1 and the neck of the reservoir.
(non représenté). De même, une bague 7, dite bague fin de bidon, peut être assemblée sur le corps de valve 1, à l'extérieur de celui-ci, pour d'une part limiter la surface de contact du joint de col 6 avec le produit contenu dans le réservoir, et d'autre part remplir le volume mort et assurer une distribution maximale du produit contenu dans le réservoir. Cette bague fin de bidon 7 peut être fixée d'une manière quelconque sur le réservoir, et notamment encliquetée comme représenté sur les dessins. Bien entendu, elle pourrait aussi être réalisée d'une seule pièce avec le corps de valve. La soupape 10 comporte un canal central traversant 11 ainsi qu'un canal latéral 12 qui débouche dans la chambre de dosage 2 lorsque la soupape est en position de distribution, comme visible sur la figure 3. La soupape 10 est sollicitée vers sa position de repos par un ressort 8, de préférence disposé dans le fond du corps de valve, et notamment dans la partie basse lb de celui-ci comme représenté sur les figures. Avantageusement, la soupape incorpore un joint 51, de préférence réalisé sous la forme d'un joint torique, assemblé autour de la soupape 10, et adapté à coopérer avec une partie de diamètre réduit 3 du corps de valve à l'intérieur de la chambre de dosage 2, pour fermer hermétiquement cette chambre de dosage lorsque la soupape arrive en position de distribution, comme représenté sur la figure 3. De manière avantageuse, la soupape comporte en outre un second joint 52, de préférence également réalisé sous la forme d'un joint annulaire ou similaire, et qui est adapté à coopérer avec le corps de valve pour obturer de manière étanche la chambre de dosage 2 en position de repos de la soupape 10, comme représenté sur la figure 2. Dans la mise en œuvre représentée sur les figures, ce second joint 52 fait partie d'une partie de support 50 de la soupape qui est directement en contact avec le ressort 8, et qui, en position de repos de la soupape 10, est sollicité par le ressort 8 en contact avec une partie du corps de valve 1, comme représenté sur la figure 2, de telle sorte que le second joint 52 obture de manière étanche la chambre de dosage 2. Par conséquent, la valve représentée sur les dessins est une valve dans laquelle la chambre de dosage est fermée hermétiquement et complètement isolée en position de repos de la valve. Ceci signifie que le contenu de la chambre de dosage ne peut pas varier indépendamment de la période de stockage de la valve, et qu'il n'y a donc aucun risque de diminution de dose pendant cette période de stockage. Le remplissage de la chambre de dosage se fait après distribution de la dose, lorsque la soupape revient de sa position de distribution vers sa position de repos, une liaison entre le réservoir (non représenté) et la chambre de dosage étant alors réalisée entre le moment où le premier joint 51 ne coopère plus avec la partie de diamètre réduit 3 et le moment où le second joint 52 ne coopère pas encore avec la partie de corps de valve décrite ci-dessus. La structure du corps de valve en deux parties, avec une partie haute la et une partie basse lb fixée, notamment encliquetée, sur la partie haute la permet une mise en place de cet élément de support 50, et favorise le mode de réalisation représenté, dans lequel le second joint 52 coopère de manière axiale avec la partie de diamètre réduite 3 du corps de valve. Selon l'invention, la soupape 10 comporte une partie de remplissage 15 qui est déplaçable entre une position de remphssage (représentée sur la figure 1) et une position d'utilisation (représentée sur les figures 2 et 3). En position de remplissage, la partie de remplissage 15 n'obture pas le canal central traversant 11 de la soupape 10, de sorte que le distributeur peut être remph à travers ledit canal central 11 de la soupape. Ce remplissage n'impose donc aucune contrainte traumatisante aux joints de la valve. Après remplissage, la partie de remphssage 15 est déplacée vers sa position d'utilisation dans laquelle elle est fixée de manière étanche à la soupape 10 et dans laquelle elle obture de manière étanche ledit canal traversant 11 de la soupape 10. Avantageusement, cette fixation étanche est réalisée par encliquetage de la partie de remplissage 15 à l'intérieur de la soupape 10. Avantageusement, comme visible sur les dessins, la partie de remplissage 15 comporte une tête conique, pourvue de préférence d'un joint d'étanchéité 18. Le canal traversant 11 comporte avantageusement une partie de canal conique 13 qui coopère avec ladite tête conique de la partie de remplissage(not shown). Likewise, a ring 7, known as the end of a canister ring, can be assembled on the valve body 1, outside of the latter, in order on the one hand to limit the contact surface of the neck seal 6 with the product. contained in the tank, and on the other hand fill the dead volume and ensure maximum distribution of the product contained in the tank. This can end ring 7 can be fixed in any way on the tank, and in particular snapped in as shown in the drawings. Of course, it could also be made in one piece with the valve body. The valve 10 has a central through channel 11 as well as a lateral channel 12 which opens into the metering chamber 2 when the valve is in the dispensing position, as visible in FIG. 3. The valve 10 is biased towards its rest position by a spring 8, preferably disposed in the bottom of the valve body, and in particular in the lower part 1b thereof as shown in the figures. Advantageously, the valve incorporates a seal 51, preferably produced in the form of an O-ring, assembled around the valve 10, and adapted to cooperate with a reduced diameter portion 3 of the valve body inside the chamber. metering 2, for hermetically closing this metering chamber when the valve reaches the dispensing position, as shown in FIG. 3. Advantageously, the valve also comprises a second seal 52, preferably also produced in the form of an annular seal or the like, and which is adapted to cooperate with the valve body for sealingly closing the metering chamber 2 in the rest position of the valve 10, as shown in FIG. 2. In the implementation shown in Figures, this second seal 52 is part of a support portion 50 of the valve which is directly in contact with the spring 8, and which, in the rest position of the valve 10, is biased pa r the spring 8 in contact with a part of the valve body 1, as shown in FIG. 2, so that the second seal 52 seals the metering chamber 2 tightly. Consequently, the valve shown in the drawings is a valve in which the metering chamber is hermetically closed and completely isolated in the valve rest position. This means that the content of the dosing chamber cannot vary independently of the valve storage period, and therefore there is no risk of dose reduction during this storage period. The filling of the dosing chamber is done after distribution of the dose, when the valve returns from its dispensing position to its rest position, a connection between the reservoir (not shown) and the metering chamber then being produced between the moment when the first seal 51 no longer cooperates with the diameter portion reduced 3 and the time when the second seal 52 does not yet cooperate with the valve body part described above. The structure of the valve body in two parts, with an upper part 1a and a lower part 1b fixed, in particular snapped on, on the upper part 1a allows this support element 50 to be put in place, and favors the embodiment shown, wherein the second seal 52 cooperates axially with the reduced diameter portion 3 of the valve body. According to the invention, the valve 10 has a filling portion 15 which is movable between a filling position (shown in Figure 1) and a position of use (shown in Figures 2 and 3). In the filling position, the filling part 15 does not close the central through channel 11 of the valve 10, so that the dispenser can be filled through said central channel 11 of the valve. This filling therefore imposes no traumatic stress on the valve seals. After filling, the filling part 15 is moved to its position of use in which it is fixed in leaktight manner to the valve 10 and in which it sealingly closes said through channel 11 of the valve 10. Advantageously, this sealed fixing is produced by snap-fastening the filling part 15 inside the valve 10. Advantageously, as visible in the drawings, the filling part 15 comprises a conical head, preferably provided with a seal 18. The through channel 11 advantageously comprises a conical channel part 13 which cooperates with said conical head of the filling part
15 lorsque celle-ci est en position d'utilisation. Le joint d'étanchéité 18 sert évidemment à améliorer cette étanchéité. Avantageusement, la partie de remplissage 15 comporte des ergots d' encliquetage 19 qui, en position d'utilisation, viennent s'encliqueter dans des logements 17 de la soupape 10 prévus à cet effet. Avantageusement, la partie de remplissage 15 est solidaire dudit élément de support 50. Après remplissage, la fixation, notamment l'encliquetage, de la partie de remplissage 15 dans la soupape 10 peut être obtenue par exemple en enfonçant à fond la soupape 10 dans le corps de valve, ce qui provoque l'encliquetage des ergots 19 dans lesdits logements 17. Après cet encliquetage, l'élément de support 50 forme une partie monobloc de la soupape 10, et cette soupape peut donc être utilisée pour distribuer le produit, en étant déplacé entre ses positions de repos et de distribution, tel que décrit ci-dessus. 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 à l'exemple représenté et décrit ci-dessus. 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. 15 when the latter is in the position of use. The seal 18 obviously serves to improve this seal. Advantageously, the filling part 15 comprises snap-on lugs 19 which, in the position of use, snap into housings 17 of the valve 10 provided for this purpose. Advantageously, the filling part 15 is integral with said support element 50. After filling, the fixing, in particular the latching of the filling part 15 in the valve 10 can be obtained for example by pushing the valve 10 fully into the valve body, which causes the lugs 19 to snap into said housings 17. After this latching, the support element 50 forms a one-piece part of the valve 10, and this valve can therefore be used to dispense the product, by being moved between its rest and dispensing positions, as described above. Although the present invention has been described with reference to a particular embodiment thereof, it is understood that it is not limited to the example shown and described above. 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.
