Description

La présente invention concerne une valve doseuse, et un dispositif de distribution de produit fluide comportant une telle valve.The present invention relates to a metering valve, and a fluid dispenser device comprising such a valve.

Les valves doseuses sont bien connues, et comportent généralement un corps de valve dans lequel coulisse une soupape entre une position de repos et une position de distribution. La valve comporte une chambre de dosage qui définit une dose de produit distribuée à chaque actionnement. Cette chambre de dosage est généralement reliée à l'orifice de distribution de la soupape lorsque celle-ci est en position de distribution, et se remplit avec le produit contenu dans le réservoir lorsque la soupape revient de sa position de distribution vers sa position de repos. Généralement, la chambre de dosage est formée par un élément tubulaire cylindrique auquel sont associées deux parois annulaires horizontales délimitant axialement ladite chambre de dosage et comportant chacune en leur centre un trou de passage pour la soupape. Pour assurer un déplacement étanche de la soupape par rapport à la chambre de dosage, on associe généralement ces deux trous de passage à des joints d'étanchéité. Un problème bien connu des valves doseuses concerne la reproductibilité ou répétitivité de la dose, c'est-à-dire un dosage précis et identique à chaque actionnement. Les chambres de dosage classiques présentent un inconvénient en ce qu'elles définissent un coin ou un angle au niveau de la jonction du tube cylindrique et des éléments de parois annulaires horizontaux. Le produit contenu dans la chambre de dosage, généralement un produit fluide comportant un gaz propulseur, est susceptible de former un ménisque au niveau de ces angles ou coins de la chambre de dosage. Ceci a pour effet de retenir du propulseur et du produit actif au niveau de ces ménisques, et donc d'altérer la précision du dosage. De même, ce type de ménisque favorise un collage du produit sur les parois de la chambre, ce qui a également pour effet d'altérer de manière négative l'homogénéité de la dose. En particulier, lorsque l'on actionne une valve doseuse, l'utilisateur appuie axialement sur la soupape et la maintient en position de distribution pendant un temps limité. Si la chambre de dosage présente un ménisque lors de l'actionnement, alors un actionnement qui serait relativement rapide de la soupape ne permettrait pas une distribution de la totalité de la dose contenue dans la chambre de dosage. Dans ce cas, pour améliorer la précision de dosage, il serait nécessaire de maintenir la soupape enfoncée en position de distribution pendant un temps relativement long, typiquement quelques secondes, ce qui serait un inconvénient important.The metering valves are well known, and generally comprise a valve body in which slides a valve between a rest position and a dispensing position. The valve has a metering chamber that defines a dose of product dispensed with each actuation. This metering chamber is generally connected to the dispensing orifice of the valve when the latter is in dispensing position, and fills with the product contained in the reservoir when the valve returns from its dispensing position to its rest position. . Generally, the metering chamber is formed by a cylindrical tubular element with which are associated two horizontal annular walls defining axially said metering chamber and each having in their center a through hole for the valve. To ensure a sealed displacement of the valve relative to the metering chamber, these two through holes are generally associated with seals. A well-known problem of the metering valves concerns the reproducibility or repeatability of the dose, that is to say a precise and identical dosage at each actuation. Conventional metering chambers have a disadvantage in that they define a corner or an angle at the junction of the cylindrical tube and the horizontal annular wall elements. The product contained in the metering chamber, generally a fluid product comprising a propellant gas, is capable of forming a meniscus at these angles or corners of the metering chamber. This has the effect of retaining the propellant and the active product at these menisci, and thus to alter the accuracy of the assay. Similarly, this type of meniscus promotes a sticking of the product on the walls of the chamber, which also has the effect of adversely affecting the homogeneity of the dose. In particular, when a metering valve is actuated, the user presses axially on the valve and keeps it in the dispensing position for a limited time. If the dosing chamber has a meniscus when actuated, then a relatively rapid actuation of the valve would not allow a distribution of the entire dose contained in the dosing chamber. In this case, to improve the dosing accuracy, it would be necessary to keep the valve depressed in dispensing position for a relatively long time, typically a few seconds, which would be a significant disadvantage.

FR 1 528 439 décrit une valve doseuse de distribution de produit fluide selon le préambule de la revendication 1.FR 1 528 439 discloses a fluid dispensing metering valve according to the preamble of claim 1.

La présente invention a pour but de fournir une valve de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés.The present invention aims to provide a fluid dispenser valve that does not reproduce the aforementioned drawbacks.

Plus particulièrement, la présente invention a pour but de fournir une valve doseuse de distribution de produit fluide qui assure une reproductibilité optimale de la dose à chaque actionnement de la valve.More particularly, the present invention aims to provide a fluid dispensing metering valve that ensures optimal dose reproducibility with each actuation of the valve.

La présente invention a également pour objet de fournir une valve doseuse de distribution de produit fluide qui améliore l'homogénéité du dosage à chaque actionnement de la valve.The present invention also aims to provide a fluid dispensing metering valve which improves the homogeneity of the dosage at each actuation of the valve.

La présente invention a encore pour but de fournir une valve doseuse de distribution de produit fluide qui soit simple et peu coûteuse à fabriquer et à assembler, et d'utilisation sûre et fiable à chaque actionnement.It is another object of the present invention to provide a fluid dispensing metering valve which is simple and inexpensive to manufacture and assemble, and which is safe and reliable to use on each actuation.

La présente invention a donc pour objet une valve doseuse de distribution de produit fluide, comportant un corps de valve, une chambre de dosage et une soupape coulissant dans ledit corps de valve pour distribuer le produit contenu dans la chambre de dosage, la paroi de ladite chambre de dosage étant au moins partiellement courbe en section axiale.The present invention therefore relates to a metering valve for fluid dispensing, comprising a valve body, a metering chamber and a valve sliding in said valve body for dispensing the product contained in the metering chamber, the wall of said metering chamber being at least partially curved in axial section.

Avantageusement, ladite chambre de dosage comporte un orifice supérieur et un orifice inférieur, ladite soupape traversant lesdits orifices supérieur et inférieur, une paroi de révolution définissant ladite chambre de dosage en reliant lesdits orifices supérieur et inférieur, ladite paroi de révolution étant au moins partiellement courbe ou arrondie de manière à ne former aucun angle.Advantageously, said metering chamber comprises an upper orifice and a lower orifice, said valve passing through said upper and lower orifices, a wall of revolution defining said metering chamber by connecting said upper and lower orifices, said wall of revolution being at least partially curved. or rounded to form no angle.

Avantageusement, ladite paroi de révolution comporte une partie de paroi médiane, une partie de paroi supérieure reliant la partie de paroi médiane audit orifice supérieur et une partie de paroi inférieure reliant la partie de paroi médiane audit orifice inférieur.Advantageously, said revolution wall comprises a median wall portion, an upper wall portion connecting the medial wall portion to said medial wall portion. upper orifice and a lower wall portion connecting the medial wall portion to said lower orifice.

Avantageusement, ladite partie de paroi médiane est cylindrique.Advantageously, said medial wall portion is cylindrical.

Avantageusement, ladite partie de paroi supérieure est arrondie, notamment sphérique.Advantageously, said upper wall portion is rounded, in particular spherical.

Avantageusement, ladite partie de paroi inférieure est arrondie, notamment sphérique.Advantageously, said lower wall portion is rounded, in particular spherical.

Avantageusement, ladite chambre de dosage est formée par deux éléments de parois fixés l'un à l'autre de manière étanche.Advantageously, said metering chamber is formed by two wall elements fixed to each other in a sealed manner.

Avantageusement, les orifices supérieur et inférieur comportent respectivement un joint d'étanchéité, lesdits éléments de paroi recouvrant sensiblement lesdits joints pour limiter la surface de contact entre lesdits joints et le produit contenu dans ladite chambre de dosage, et/ou limiter le battement de ces joints lors de l'actionnement.Advantageously, the upper and lower orifices respectively comprise a seal, said wall elements substantially covering said seals to limit the contact surface between said seals and the product contained in said dosing chamber, and / or limit the beat of these joints when actuated.

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

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 au dessin joint, donné à titre d'exemple non limitatif, et qui représente sur la figure unique, une vue schématique en section transversale d'une valve doseuse selon un mode de réalisation avantageux de la présente invention.Other features and advantages of the present invention will appear more clearly in the following detailed description of a particular embodiment thereof, with reference to the accompanying drawing, given by way of non-limiting example, and which represents in the single figure, a schematic cross-sectional view of a metering valve according to an advantageous embodiment of the present invention.

En référence à la figure unique, la valve comporte un corps de valve 10 et une soupape 30. Une chambre de dosage 20 est définie dans la valve, et la soupape 30 coulisse par rapport au corps de valve 10 entre une position de repos (représentée sur la figure) et une position de distribution (non représentée), dans laquelle la soupape est enfoncée axialement à l'intérieur du corps de valve 10. Cette valve doseuse est destiné à être assemblée sur un réservoir de produit fluide (non représenté), par exemple au moyen d'une bague ou capsule de fixation 60 qui peut être d'un type quelconque. De manière classique, la chambre de dosage 20 est isolée du réservoir lorsque la soupape 30 est déplacée vers sa position de distribution, dans laquelle l'intérieur de la chambre de dosage 20 est relié à l'orifice de distribution 35 de la soupape 30. Lorsque l'utilisateur relâche sa pression sur la soupape 30, celle-ci revient automatiquement vers sa position de repos sous l'effet du ressort de rappel 50, et pendant ce retour, la chambre de dosage 20 est reliée au réservoir d'une manière quelconque connue, permettant le remplissage de cette chambre de dosage sous l'effet de la dépression créée par la distribution de la dose précédente, et/ou par gravité si ladite valve est utilisée en position inversée.Referring to the single figure, the valve comprises a valve body 10 and a valve 30. A dosing chamber 20 is defined in the valve, and the valve 30 slides relative to the valve body 10 between a rest position (shown in FIG. in the figure) and a dispensing position (not shown), in which the valve is pressed axially inside the valve body 10. This metering valve is intended to be assembled on a fluid reservoir (not shown), for example by means of a ring or fixing cap 60 which can be of any type. In a conventional manner, the metering chamber 20 is isolated from the reservoir when the valve 30 is moved to its position of distribution, in which the inside of the metering chamber 20 is connected to the dispensing orifice 35 of the valve 30. When the user releases its pressure on the valve 30, the latter automatically returns to its rest position under the effect of the return spring 50, and during this return, the metering chamber 20 is connected to the tank in any known manner, allowing the filling of this metering chamber under the effect of the depression created by the distribution of the previous dose, and / or by gravity if said valve is used in the inverted position.

Selon l'invention, la chambre de dosage 20 est au moins partiellement courbe en section axiale. Par section axiale on entend un plan de section qui comporte l'axe central X de la valve, comme représenté sur la figure. Plus précisément, comme cela est visible sur la figure unique, la chambre de dosage 20 comporte une paroi de révolution 27 qui relie l'orifice supérieur 25 à l'orifice inférieur 26, la soupape 30 traversant ces orifices inférieur et supérieur lors de son déplacement entre ses positions de repos et de distribution. Cette paroi de révolution 27 est avantageusement et au moins partiellement courbe ou arrondie de manière à ne former aucun angle. Par courbe ou arrondie on entend que cette paroi ne comporte sensiblement aucune arête, ou angle abrupte, comme cela serait le cas par exemple sur une surface polygonale. L'absence d'angle ou de coin dans la chambre de dosage permet d'éviter la formation d'un ménisque, et améliore donc la reproductibilité et l'homogénéité du dosage à chaque actionnement de la valve.According to the invention, the metering chamber 20 is at least partially curved in axial section. By axial section is meant a section plane which comprises the central axis X of the valve, as shown in FIG. More specifically, as can be seen in the single figure, the metering chamber 20 has a revolution wall 27 which connects the upper orifice 25 to the lower orifice 26, the valve 30 passing through these lower and upper openings during its displacement. between its rest and distribution positions. This wall of revolution 27 is advantageously and at least partially curved or rounded so as to form no angle. Curved or rounded means that this wall has substantially no edge, or steep angle, as would be the case for example on a polygonal surface. The absence of an angle or corner in the metering chamber avoids the formation of a meniscus, and thus improves the reproducibility and homogeneity of the dosage at each actuation of the valve.

Avantageusement, la paroi de révolution 27 comporte une partie de paroi médiane 22, qui peut avantageusement être cylindrique. Cette partie de paroi médiane 22 est reliée à l'orifice supérieur 25 par une partie de paroi supérieure 21 et à l'orifice inférieur 26 par une partie de paroi inférieure 23. Ces parties de parois supérieure et/ou inférieure sont de préférence arrondies ou courbes, notamment sphériques ou elliptiques, afin d'éviter toute formation de ménisque à ce niveau.Advantageously, the revolution wall 27 comprises a median wall portion 22, which may advantageously be cylindrical. This middle wall portion 22 is connected to the upper orifice 25 by an upper wall portion 21 and to the lower orifice 26 by a lower wall portion 23. These upper and / or lower wall portions are preferably rounded or curves, especially spherical or elliptical, to prevent meniscus formation at this level.

Dans le mode de réalisation représenté sur la figure unique, la chambre de dosage 20 est en fait formée par deux éléments de parois 28, 29 qui sont fixés l'un à l'autre de manière étanche. Chaque élément de paroi peut donc être à la fois partiellement arrondi, courbe ou sphérique, et partiellement cylindrique.In the embodiment shown in the single figure, the metering chamber 20 is in fact formed by two wall elements 28, 29 which are fixed to each other in a sealed manner. Each wall element can therefore be both partially rounded, curved or spherical, and partially cylindrical.

Cette mise en oeuvre présente en outre un avantage supplémentaire, à savoir que les joints d'étanchéité 45, 46 qui sont associés aux orifices supérieur et inférieur 25, 26, et contre lesquels la soupape 30 coulisse lors de son déplacement, sont sensiblement recouverts par lesdits éléments de parois courbes 28 et 29, ce qui a pour effet de limiter la surface de contact entre lesdits joints 45, 46 et le produit fluide contenu dans ladite chambre de dosage 20. Ceci peut avoir un effet bénéfique selon la nature du produit fluide à distribuer, notamment lorsqu'il s'agit d'un produit pharmaceutique. De plus, le battement des joints d'étanchéité est avantageusement limité lors de l'actionnement par la présence de ces parois supérieure et inférieure arrondiesThis implementation has the further advantage that the seals 45, 46 which are associated with the upper and lower holes 25, 26, and against which the valve 30 slides during its movement, are substantially covered by said curved wall elements 28 and 29, which has the effect of limiting the contact surface between said seals 45, 46 and the fluid contained in said metering chamber 20. This may have a beneficial effect depending on the nature of the fluid product to be distributed, particularly in the case of a pharmaceutical product. In addition, the beat of the seals is advantageously limited during actuation by the presence of these rounded upper and lower walls.

La présente invention a été décrite en référence à un mode de réalisation particulier de celle-ci. Bien entendu, diverses modifications sont envisageables. Par exemple, la structure de la valve, et notamment du corps de valve ou de la soupape pourrait être modifiée. De même, la forme arrondie de la chambre de dosage pourrait être différente de celle représentée, à condition qu'elle évite toute formation de ménisque, et donc toute présence de coin, d'arête ou d'angle susceptible de favoriser une telle création de ménisque. D'autres modifications sont également envisageables pour l'homme du métier sans sortir du cadre de la présente invention tel que défini par les revendications annexées.The present invention has been described with reference to a particular embodiment thereof. Of course, various modifications are possible. For example, the structure of the valve, and in particular of the valve body or the valve could be modified. Similarly, the rounded shape of the metering chamber could be different from that shown, provided that it avoids any meniscus formation, and therefore any presence of corner, edge or angle likely to promote such creation of meniscus. Other modifications are also conceivable for those skilled in the art without departing from the scope of the present invention as defined by the appended claims.
