Description

La présente invention concerne une valve de distribution de produit fluide.The present invention relates to a fluid dispenser valve.

Plus particulièrement, la présente invention concerne une valve dite doseuse, dans laquelle à chaque actionnement de la valve, une dose précise de produit fluide est distribuée. Ces valves sont bien connues dans l'état de la technique, et sont généralement assemblées sur un réservoir contenant le produit fluide et un gaz propulseur utilisé pour réaliser l'expulsion de la dose. On connaît notamment deux types de valves doseuses, à savoir d'une part celles qui après remplissage de la chambre de dosage obturent celle-ci de manière étanche jusqu'au prochain actionnement de la valve, et d'autre part celles qui ne se remplissent que juste avant l'actionnement proprement dit. Dans la première catégorie, il peut se poser un problème de dose incomplète et/ou de non homogénéité de la dose au moment de son expulsion, en particulier si la valve a été stockée pendant un certain temps, ce qui fait que le produit actif n'est plus réparti de manière parfaitement homogène dans la chambre de dosage. Pour éviter ce problème, les valves de la deuxième catégorie permettent à la chambre de dosage de se remplir rapidement au moment où l'utilisateur va actionner la valve. Avec ce type de valve, après chaque actionnement, la chambre de dosage peut se remplir à nouveau, mais si ensuite la valve est stockée en position droite, alors cette chambre de dosage peut se vider dans le réservoir, la chambre de dosage n'étant alors pas obturée de manière étanche. Les documents FR-2 860 503 et GB2 405 667 décrivent des valves de l'art antérieur.More particularly, the present invention relates to a so-called metering valve, in which each actuation of the valve, a precise dose of fluid is dispensed. These valves are well known in the state of the art, and are generally assembled on a reservoir containing the fluid and a propellant gas used to achieve the expulsion of the dose. Two types of metering valves are known, namely, on the one hand, those which, after filling of the metering chamber, seal off the latter until the next operation of the valve, and on the other hand those which are not filled. than just before the actual actuation. In the first category, there may be a problem of incomplete dose and / or non-homogeneity of the dose at the time of expulsion, particularly if the valve has been stored for a certain period of time, so that the active ingredient is more evenly distributed in the metering chamber. To avoid this problem, the valves of the second category allow the metering chamber to fill quickly when the user will operate the valve. With this type of valve, after each actuation, the metering chamber can refill, but if the valve is stored in the upright position, then this metering chamber can be emptied into the reservoir, the metering chamber being then not sealed tightly. The documents FR-2,860,503 and GB2 405 667 describe valves of the prior art.

La présente invention a pour but d'améliorer les valves doseuses de la seconde catégorie, c'est-à-dire celles dans lesquelles la chambre de dosage n'est pas obturée de manière étanche en positon de repos de la soupape.The present invention aims to improve the metering valves of the second category, that is to say those in which the metering chamber is not sealed in a rest position of the valve.

La présente invention a notamment pour but de fournir une valve de distribution de produit fluide qui soit simple et peu coûteuse à fabriquer et à assembler, et de fonctionnement fiable.The present invention is intended in particular to provide a fluid dispenser valve that is simple and inexpensive to manufacture and assemble, and reliable operation.

La présente invention a également pour but de fournir une valve de distribution de produit fluide permettant un remplissage aisé et sûr de la chambre de dosage avant chaque actionnement tout en garantissant une bonne fiabilité de fonctionnement de ladite valve.The present invention also aims to provide a fluid dispensing valve for easy and safe filling of the metering chamber before each actuation while ensuring a good operating reliability of said valve.

La présente invention a donc pour objet une valve de distribution de produit fluide selon la revendication 1. Des modes de réalisation avantageux sont décrits dans les revendications dépendantes.The present invention therefore relates to a fluid dispenser valve according to claim 1. Advantageous embodiments are described in the dependent claims.

La présente invention a également pour objet un dispositif de distribution de produit fluide comportant une valve telle que décrite ci-dessus.The present invention also relates to a fluid dispenser device comprising a valve as described above.

Ces caractéristiques et avantages et d'autres de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante de trois modes de réalisation 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 premier mode de réalisation de la présente invention, en position de repos,
  • La figure 2 est une vue de détail en perspective de la partie inférieure de la soupape de la valve de la figure 1,
  • La figure 3 est une vue similaire à celle de la figure 1, montrant un second mode de réalisation de la présente invention, et
  • La figure 4 est une vue similaire à celles des figures 1 et 3, montrant un troisième mode de réalisation, qui ne fait pas partie de la présente invention.
These and other features and advantages of the present invention will appear more clearly in the following detailed description of three embodiments thereof 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 dispensing valve according to a first embodiment of the present invention, in the rest position,
  • The figure 2 is a detail view in perspective of the lower part of the valve of the valve of the figure 1 ,
  • The figure 3 is a view similar to that of the figure 1 showing a second embodiment of the present invention, and
  • The figure 4 is a view similar to those of figures 1 and 3 , showing a third embodiment, which is not part of the present invention.

La valve représentée sur la figure 1 comporte un corps de valve 10 à l'intérieur duquel coulisse une soupape 30 entre une position de repos, qui est celle représentée sur la figure, et une position de distribution dans laquelle la soupape 30 est enfoncée à l'intérieur du corps de valve 10. Cette valve est généralement destinée à être assemblée sur un réservoir (non représenté), de préférence au moyen d'un élément de fixation 5, qui peut être une capsule à sertir, à visser ou à encliqueter, et avantageusement avec interposition d'un joint de col 6. Éventuellement, une bague (non représentée) peut être assemblée autour du corps de valve, notamment pour diminuer le volume mort en position inversée et pour limiter le contact du produit fluide avec le joint de col. La soupape 30 est sollicitée vers sa position de repos par un ressort 8, qui est disposé dans le corps de valve 10 et qui coopère d'une part avec ce corps de valve 10, et d'autre part avec une collerette radiale de support 320 de la soupape 30. Une chambre de dosage 20 est définie à l'intérieur du corps de valve 10, ladite soupape 30 coulissant à l'intérieur de ladite chambre de dosage pour permettre la distribution du contenu de celle-ci lorsque la valve est actionnée. La chambre de dosage est de préférence définie entre deux joints annulaires, un joint de soupape 21 et un joint de chambre 22, de manière bien connue. La figure 1 représente la valve en position de repos de la soupape et en position droite, c'est-à-dire la position dans laquelle la chambre de dosage 20 est disposée au-dessus du réservoir (non représenté). La soupape 30 comporte un orifice de sortie 301 relié à un orifice d'entrée 302, qui est disposé dans la chambre de dosage 20 lorsque la soupape 30 est en position de distribution.The valve shown on the figure 1 comprises a valve body 10 within which a valve 30 slides between a rest position, which is that shown in the figure, and a dispensing position in which the valve 30 is depressed inside the valve body 10 This valve is generally intended to be assembled on a tank (not shown), preferably by means of a fixing element 5, which can be a crimp cap, to screw or snap, and advantageously with the interposition of a neck seal 6. Optionally, a ring (not shown) can be assembled around the valve body, in particular to reduce the dead volume in the inverted position and to limit the contact of the fluid product with the neck seal. The valve 30 is urged towards its rest position by a spring 8, which is arranged in the valve body 10 and which cooperates on the one hand with this valve body 10, and on the other hand with a radial support flange 320 of the valve 30. A dosing chamber 20 is defined inside the valve body 10, said valve 30 sliding inside said dosing chamber to allow dispensing of the contents thereof when the valve is actuated. . The metering chamber is preferably defined between two annular seals, a valve seal 21 and a chamber seal 22, as is well known. The figure 1 represents the valve in the rest position of the valve and in the upright position, that is to say the position in which the metering chamber 20 is disposed above the reservoir (not shown). The valve 30 has an outlet port 301 connected to an inlet port 302, which is disposed in the metering chamber 20 when the valve 30 is in the dispensing position.

Afin d'améliorer le guidage de la soupape 30 et donc assurer un fonctionnement fiable de la valve, la surface périphérique externe de la collerette 320 est de préférence de forme environ correspondante à celle du corps de valve 10, c'est-à-dire généralement cylindrique, et est avantageusement disposée à faible distance dudit corps de valve pour éviter tout risque de décalage axial de ladite soupape lors de son actionnement.In order to improve the guiding of the valve 30 and thus to ensure reliable operation of the valve, the outer peripheral surface of the valve flange 320 is preferably approximately corresponding in shape to that of the valve body 10, that is to say generally cylindrical, and is advantageously arranged at a small distance from said valve body to avoid any risk of axial offset of said valve when its actuation.

Comme visible sur la figure 1, lorsque la soupape 30 est en position de repos, la chambre de dosage 20 est en permanence reliée au réservoir, puisque la chambre de dosage 20 n'est pas obturée de manière étanche dans cette position de repos de la soupape 30. Lorsque la valve est stockée en position droite, la chambre de dosage se vide donc et lorsque l'utilisateur souhaite réutiliser la valve, il faudra qu'il la retourne en position inversée, c'est-à-dire la position dans laquelle la chambre de dosage 20 est disposée en dessous du réservoir, de sorte que celle-ci pourra se remplir par gravité.As visible on the figure 1 when the valve 30 is in the rest position, the metering chamber 20 is permanently connected to the reservoir, since the metering chamber 20 is not sealed in this rest position of the valve 30. When the valve is stored in the upright position, the metering chamber is empty so and when the user wishes to reuse the valve, it will have to return it in the inverted position, that is to say the position in which the metering chamber 20 is arranged below the tank, so that it can fill by gravity.

Selon l'invention, pour favoriser un remplissage rapide et fiable de la chambre de dosage, le passage d'écoulement de fluide entre la chambre de dosage 20 et le réservoir passe, au niveau de la collerette 320, au moins partiellement à l'intérieur de la soupape 30. Plus précisément, du fait du faible écart entre la périphérie externe de la collerette 320 et le corps de valve 10, un écoulement passant exclusivement à l'extérieur de la soupape peut être entravé ou au moins ralenti, ce qui peut poser des problèmes de dosage lorsque l'utilisateur actionne la valve relativement vite après l'avoir positionnée en position inversée. Le fait de prévoir un passage d'écoulement de fluide 35 au moins partiellement à l'intérieur de la soupape 30 permet de garantir un écoulement plus rapide et donc un remplissage plus fiable de cette chambre de dosage 20. Comme visible plus précisément sur la figure 2, la collerette radiale peut comporter une paroi périphérique 320 de préférence sensiblement annulaire ou cylindrique, et au moins un passage axial traversant, avantageusement au moins deux, de préférence au moins trois passages. L'exemple représenté sur la figure 2 comporte même quatre passages traversants 35. Ces passages 35 sont définis radialement à l'intérieur de la paroi périphérique 320, et autour d'un noyau central de la soupape.According to the invention, to promote rapid and reliable filling of the metering chamber, the fluid flow passage between the metering chamber 20 and the reservoir passes, at the collar 320, at least partially inside. of the valve 30. Specifically, because of the small gap between the outer periphery of the collar 320 and the valve body 10, a flow passing exclusively outside the valve can be hindered or at least slowed, which can to pose problems of dosage when the user actuates the valve relatively quickly after having positioned it in inverted position. The fact of providing a fluid flow passage 35 at least partially inside the valve 30 makes it possible to guarantee a faster flow and therefore a more reliable filling of this metering chamber 20. As can be seen more precisely on FIG. figure 2 the radial flange may comprise a peripheral wall 320 which is preferably substantially annular or cylindrical, and at least one axial through-passage, advantageously at least two, preferably at least three, passages. The example shown on the figure 2 even has four through passages 35. These passages 35 are defined radially inside the peripheral wall 320, and around a central core of the valve.

Dans l'exemple des figures 1 et 2, la soupape 30 est réalisée en deux parties, à savoir une partie haute 31 (également appelée haut de soupape) et une partie basse 32 (également appelée bas de soupape) en regardant dans la position droite de la figure 1. La partie basse 32 est dans ce mode de réalisation assemblée à l'intérieur de la partie haute 31, et la collerette 320 fait partie intégrante de cette partie basse 32 comme clairement visible sur la figure 2.In the example of Figures 1 and 2 , the valve 30 is made in two parts, namely an upper part 31 (also called high valve) and a lower part 32 (also called bottom valve) looking in the right position of the figure 1 . The lower part 32 is in this embodiment assembled inside the upper part 31, and the collar 320 is an integral part of this lower part 32 as clearly visible on the figure 2 .

La figure 3 représente une seconde variante de réalisation de la présente invention, dans laquelle la collerette 320 fait partie d'une pièce tubulaire 32' qui est assemblée, de préférence emmanchée, autour de la soupape 30. Dans cet exemple de réalisation, la soupape 30 est sensiblement réalisée d'une seule pièce monobloc, et c'est la pièce tubulaire 32' qui définit à la fois la collerette 320 permettant un guidage efficace de la soupape lors de son actionnement ainsi que le ou les passage(s) traversant(s) 35 pour l'écoulement du fluide tel que décrit en référence au premier mode de réalisation représenté sur les figures 1 et 2. Cette mise en oeuvre fournit une meilleure rigidité du fait qu'il n'y a pas d'assemblage d'une partie basse et d'une partie haute de la soupape. Comme schématiquement représenté sur la figure 3, l'intérieur des passage(s) traversant(s) 35 peut comporter des profils inclinés ou en hélice pour donner au produit, lorsqu'il passe à travers ces passages, un mouvement légèrement tourbillonnaire ce qui va favoriser une bonne homogénéisation de la dose lorsque celle-ci va rentrer dans la chambre de dosage 20. Cette mise en oeuvre pourrait également être prévue dans le mode de réalisation des figures 1 et 2.The figure 3 represents a second embodiment of the present invention, wherein the flange 320 is part of a tubular piece 32 'which is assembled, preferably fitted, around the valve 30. In this embodiment, the valve 30 is substantially made in one piece piece, and it is the tubular piece 32 'which defines both the flange 320 for effective guiding of the valve during its actuation and the passage (s) crossing (s) 35 for the flow of the fluid as described with reference to the first embodiment shown on the Figures 1 and 2 . This implementation provides better rigidity because there is no assembly of a lower part and an upper part of the valve. As schematically represented on the figure 3 , the interior of the passage (s) crossing (s) 35 may comprise inclined or helical profiles to give the product, as it passes through these passages, a slightly swirling movement which will promote a good homogenization of the dose when it will enter the metering chamber 20. This implementation could also be provided in the embodiment of the invention. Figures 1 and 2 .

Sur la figure 4, il est représenté un autre mode de réalisation qui ne fait pas partie de la présente invention, dans lequel le passage d'écoulement 35' s'étend, au niveau de la collerette 320, au moins partiellement à l'intérieur de la soupape 30, notamment de manière axiale et centrale. Dans l'exemple de la figure 4, la soupape est à nouveau constituée de deux parties, une partie supérieure 31 et une partie inférieure 32, la partie inférieure 32 étant assemblée à l'intérieur de la partie supérieure 31. Avantageusement, le passage axial interne 35' s'étend à l'intérieur de la partie inférieure 32 sur une majeure partie de sa hauteur, avantageusement à partir de l'extrémité axiale inférieure qui est ouverte 352 jusqu'à une ouverture latérale 351 disposée, au-dessus de la collerette 320, avantageusement à proximité de l'interface entre la partie inférieure et la partie supérieure. Cette ouverture latérale 351 débouche au moins partiellement dans la chambre de dosage 20 pour permettre son remplissage. Le passage d'écoulement 35' s'étend donc entre l'extrémité inférieure de la soupape et une partie intermédiaire de celle-ci. L'exemple représenté sur la figure 4 implique un double flux à la fois lors du remplissage et du vidage de la chambre de dosage 20, une première partie du flux (généralement la partie principale) passant à l'intérieur de la soupape 30 dans le passage d'écoulement axial 35', et une autre partie du flux passant à l'extérieur de la soupape 30 et à l'extérieur de la collerette 320. Ce double flux permet également de favoriser une dose homogène à l'intérieur de la chambre de dosage au moment de la distribution de celle-ci. En variante, la soupape 30 peut coopérer à l'extérieur de manière étanche avec le joint 22 de la chambre de dosage 20, en toutes positions, de sorte que le passage d'écoulement 35' entre la chambre de dosage et le réservoir passe exclusivement à l'intérieur de la soupape 30. Selon une variante, la collerette 320, qui est pleine sur l'exemple de la figure 4, pourrait aussi comporter un ou plusieurs passages traversants ou fentes pour le produit fluide. Ces passages ou fentes pourraient aussi être prévues sur la partie de soupape disposée entre la collerette 320 et le joint 22. Ceci permettrait de limiter le volume mort, notamment dans une configuration similaire à celle de la figure 4, mais où le joint 22 coopérerait de manière étanche avec l'extérieur de la soupape, favorisant ainsi le remplissage en position inversée.On the figure 4 there is shown another embodiment which is not part of the present invention, wherein the flow passage 35 'extends at the collar 320 at least partially within the valve 30 , especially axially and centrally. In the example of the figure 4 , the valve is again made up of two parts, an upper part 31 and a lower part 32, the lower part 32 being assembled inside the upper part 31. Advantageously, the internal axial passage 35 'extends to the upper part 31. interior of the lower part 32 on a major part of its height, advantageously from the lower axial end which is open 352 to a lateral opening 351 disposed above the collar 320, advantageously near the interface between the lower part and the upper part . This lateral opening 351 opens at least partially into the metering chamber 20 to allow its filling. The flow passage 35 'therefore extends between the lower end of the valve and an intermediate portion thereof. The example shown on the figure 4 involves a double flow at a time during filling and emptying of the metering chamber 20, a first part of the flow (usually the main part) passing inside the valve 30 in the axial flow passage 35 ', and another part of the flow passing outside the valve 30 and outside the collar 320. This double flow also makes it possible to promote a homogeneous dose inside the dosing chamber at the time of dispensing. it. In a variant, the valve 30 can co-operate externally in a sealed manner with the seal 22 of the metering chamber 20, in any position, so that the flow passage 35 'between the metering chamber and the reservoir passes exclusively inside the valve 30. According to a variant, the flange 320, which is solid on the example of the figure 4 could also include one or more through passages or slots for the fluid product. These passages or slots could also be provided on the valve portion disposed between the flange 320 and the seal 22. This would limit the dead volume, especially in a configuration similar to that of the figure 4 but where the seal 22 cooperates sealingly with the outside of the valve, thus promoting the filling in the inverted position.

Bien que la présente invention ait été décrite en référence à plusieurs modes de réalisation de celle-ci, il est entendu qu'elle n'est pas limitée par les exemples représentés.
