Description

Dispositif de distribution de produit liquide muni d'un organe de réduction de débit  Liquid product dispensing device provided with a flow reduction member
La présente invention concerne un embout de distribution de liquide, notamment dans le domaine pharmaceutique, tel que du liquide auriculaire, buccal ou ophtalmique. The present invention relates to a liquid dispensing tip, particularly in the pharmaceutical field, such as auricular liquid, oral or ophthalmic.
On entend par « produit liquide » un produit non solide et non gazeux. On comprend que le produit peut être plus ou moins liquide, selon sa viscosité. Aussi, on inclut dans « produit liquide » un produit pâteux ou semi-liquide.  The term "liquid product" means a non-solid and non-gaseous product. It is understood that the product can be more or less liquid, depending on its viscosity. Also, it includes in "liquid product" a pasty or semi-liquid product.
On connaît du document WO 2004/069679, un embout de distribution de liquide rapporté sur un réservoir à paroi déformable. Cet embout de distribution comprend un canal longitudinal de sortie de liquide ainsi qu'un insert définissant avec une paroi de l'embout un canal essentiellement longitudinal de limitation de débit.  Document WO 2004/069679 discloses a liquid distribution tip attached to a tank with a deformable wall. This dispensing nozzle comprises a longitudinal liquid outlet channel and an insert defining with a wall of the nozzle a substantially longitudinal flow limiting channel.
Cependant, cet embout peut être volumineux, tout particulièrement lorsque le liquide est peu visqueux, car, afin d'augmenter la perte de charge créée au sein du liquide, il faut alors augmenter la longueur du canal de limitation de débit et donc augmenter la dimension longitudinale de l'insert.  However, this tip can be bulky, especially when the liquid is low viscosity, because, in order to increase the pressure loss created within the liquid, it is necessary to increase the length of the flow limiting channel and therefore increase the size. longitudinal of the insert.
Une autre solution peut être d'augmenter la longueur du canal et/ou de réduire la section du canal de limitation de débit. Toutefois, la réalisation de canaux de limitation de débit de section de passage faible est particulièrement difficile à réaliser pour des productions en grande série, plus particulièrement lorsque ces canaux ont une longueur importante.  Another solution may be to increase the length of the channel and / or reduce the section of the flow limiting channel. However, the realization of flow rate limiting channels of low passage section is particularly difficult to achieve for mass production, especially when these channels have a significant length.
La présente invention a notamment pour but de fournir un dispositif de distribution compact et simple à réaliser.  The present invention is intended to provide a compact distribution device and simple to achieve.
A cet effet, l'invention a notamment pour objet un dispositif de distribution de produit liquide, le dispositif comprenant :  For this purpose, the subject of the invention is in particular a device for dispensing liquid product, the device comprising:
- un embout de distribution comprenant une cavité ayant un fond à partir duquel s'étend un canal longitudinal de sortie du liquide, et  a dispensing nozzle comprising a cavity having a bottom from which extends a longitudinal outlet channel of the liquid, and
- un organe de réduction de débit, rapporté dans la cavité de l'embout, comportant une surface transversale délimitant, avec le fond de l'embout, un canal de déviation du liquide s'étendant dans un plan transversal, le canal de déviation étant non rectiligne.  - A flow reduction member, reported in the cavity of the nozzle, having a transverse surface defining, with the bottom of the nozzle, a liquid deflection channel extending in a transverse plane, the deflection channel being not rectilinear.
On entend par « canal non rectiligne » un canal présentant une trajectoire qui permet d'augmenter les pertes de charges au sein du liquide, soit par augmentation de la longueur du canal, soit par création de perturbations locales de l'écoulement du liquide (tel qu'un changement abrupt de direction de l'écoulement ou d'un changement abrupt de section du canal).  The term "non-rectilinear channel" means a channel having a trajectory which makes it possible to increase the pressure losses within the liquid, either by increasing the length of the channel or by creating local disturbances of the flow of the liquid (such as abrupt change of direction of flow or abrupt change of channel section).
Ainsi, ce canal peut être courbe et, par exemple, prendre la forme d'une spirale. Le canal peut également comprendre plusieurs segments consécutifs non alignés, c'est-à-dire que deux segments consécutifs forment un angle entre eux différent de 180°, de préférence compris entre 10 et 90°. Thus, this channel may be curved and, for example, take the form of a spiral. The channel may also comprise several consecutive non-aligned segments, that is to say that two consecutive segments form an angle between them different from 180 °, preferably between 10 and 90 °.
On notera que le canal longitudinal de sortie de liquide débouche généralement directement sur l'orifice de sortie du liquide, ménagé sur l'embout.  It will be noted that the longitudinal liquid outlet channel generally opens directly onto the outlet orifice of the liquid formed on the nozzle.
On notera également que le canal de déviation du liquide s'étend dans un plan transversal, c'est-à-dire que la génératrice de ce canal se trouve dans un plan transversal. Ce canal se distingue par exemple d'un canal hélicoïdal.  It will also be noted that the liquid deflection channel extends in a transverse plane, that is to say that the generatrix of this channel is in a transverse plane. This channel is distinguished for example from a helical channel.
On comprend toutefois que, outre le canal de déviation défini ci-dessus, le dispositif peut également comporter d'autres canaux de limitation de débit, tel qu'un canal hélicoïdal, un canal à section restreinte, etc.  However, it is understood that, in addition to the deflection channel defined above, the device may also include other flow limiting channels, such as a helical channel, a restricted section channel, etc.
On obtient ainsi un dispositif de distribution de liquide simple et compact pour contrôler la distribution du liquide. En effet, comme on dispose le canal de déviation du liquide dans un plan transversal, on peut prévoir un organe de réduction de débit de dimension réduite dans la direction longitudinale. Plus précisément, on modifie la géométrie du canal de déviation dans le plan transversal, de façon à créer les pertes de charges désirées sans avoir forcément besoin d'augmenter la hauteur de l'organe de réduction de débit, dans la direction longitudinale.  A simple and compact liquid distribution device is thus obtained for controlling the distribution of the liquid. Indeed, since the liquid deflection channel is arranged in a transverse plane, it is possible to provide a flow reduction device of reduced size in the longitudinal direction. More precisely, the geometry of the deflection channel in the transverse plane is modified so as to create the desired head losses without necessarily having to increase the height of the flow reduction member in the longitudinal direction.
On comprend que l'on peut créer des pertes de charges au sein du liquide, soit en modifiant la section et/ou la longueur du canal de déviation, soit en générant des perturbations locales dans l'écoulement du liquide.  It is understood that one can create losses within the liquid, either by modifying the section and / or the length of the deflection channel, or by generating local disturbances in the flow of the liquid.
Grâce au fait que l'organe est rapporté à l'intérieur de l'embout, il est aisé et économique de modifier les paramètres d'écoulement du liquide. En effet, en modifiant uniquement l'organe de réduction de débit ou le fond de l'embout, on peut modifier le canal de déviation de débit pour définir un canal d'une section différente, d'une longueur différente et/ou d'une géométrie différente.  Because the member is attached to the interior of the nozzle, it is easy and economical to change the flow parameters of the liquid. By modifying only the flow reduction member or the bottom of the mouthpiece, the flow deflection channel can be modified to define a channel of a different section, of a different length and / or a different geometry.
Lors de la distribution de liquide sous forme de gouttes, correspondant au mode de distribution préférentiel, on peut ainsi adapter le canal de déviation du liquide à la viscosité du liquide à distribuer et/ou à la taille de la goutte que l'on désire délivrer.  During the distribution of liquid in the form of drops, corresponding to the preferred mode of distribution, it is thus possible to adapt the channel of deviation of the liquid to the viscosity of the liquid to be dispensed and / or to the size of the drop that it is desired to deliver .
Ce dispositif est particulièrement intéressant pour mieux maîtriser la taille de la goutte délivrée, c'est-à-dire la quantité de médicament délivré, en permettant de s'affranchir des paramètres extérieurs intervenant lors de la délivrance d'une goutte de liquide, tels que la rigidité du réservoir, l'état des surfaces, la force et la vitesse avec lesquelles l'utilisateur appuie sur les parois du réservoir, voire d'éventuels tremblements de l'utilisateur. Ainsi, pour un réservoir donné et un liquide de viscosité connue, on peut déterminer la géométrie du canal de déviation de liquide qui permettra d'assurer la reproductibilité de la quantité de liquide délivré à chaque pression de l'utilisateur. This device is particularly interesting for better controlling the size of the droplet delivered, that is to say the amount of drug delivered, by eliminating the external parameters involved during the delivery of a drop of liquid, such as that the rigidity of the tank, the state of the surfaces, the force and the speed with which the user presses on the walls of the tank, or even possible tremors of the user. Thus, for a given reservoir and a liquid of known viscosity, it is possible to determine the geometry of the liquid deflection channel which will make it possible to reproduce the quantity of liquid delivered with each pressure of the user.
Le dispositif peut en outre comporter l'une ou plusieurs des caractéristiques suivantes.  The device may further include one or more of the following features.
- Le fond de l'embout comprend une surface transversale sensiblement plane et la surface transversale de l'organe de réduction de débit comprend des reliefs délimitant, avec le fond de l'embout, le canal de déviation du liquide. On peut donc modifier les reliefs de la surface transversale de l'organe pour définir, avec la surface transversale de l'embout, un canal d'une section différente, d'une longueur différente et/ou d'une géométrie différente. On peut ainsi utiliser un embout de forme standard et adapter uniquement l'organe de réduction en fonction du type de liquide qui est distribué.  - The bottom of the nozzle comprises a substantially flat transverse surface and the transverse surface of the flow reduction member comprises reliefs defining, with the bottom of the nozzle, the liquid deflection channel. It is therefore possible to modify the reliefs of the transverse surface of the member to define, with the transverse surface of the tip, a channel of a different section, of a different length and / or a different geometry. It is thus possible to use a standard-shaped nozzle and adapt only the reduction member depending on the type of liquid that is dispensed.
- L'organe de réduction de débit comprend une base ayant une fonction de support, portant les reliefs, dont la hauteur dans la direction longitudinale est supérieure à la hauteur des reliefs. L'épaisseur importante de la base permet d'assurer un plaquage des reliefs contre la surface transversale de l'embout. Ainsi, on procure une certaine rigidité à cet organe et on s'assure que l'étanchéité entre l'organe et la surface transversale de l'embout est garantie. On comprend donc que l'organe de réduction de débit est non poreux, c'est-à-dire que le liquide ne peut pas passer à travers les parois de l'organe. Par conséquent, le liquide est contraint à parcourir tout le canal de déviation du liquide, c'est-à-dire que la pression du liquide ne peut pas déformer l'organe et donc le canal de façon à court-circuiter une partie du canal de déviation.  - The flow reduction member comprises a base having a support function, bearing the reliefs, the height in the longitudinal direction is greater than the height of the reliefs. The large thickness of the base ensures a plating reliefs against the transverse surface of the tip. Thus, it provides a certain rigidity to this member and it is ensured that the seal between the member and the transverse surface of the tip is guaranteed. It is therefore understood that the flow reduction member is non-porous, that is to say that the liquid can not pass through the walls of the organ. Consequently, the liquid is forced to traverse the entire liquid deflection channel, that is to say that the liquid pressure can not deform the organ and therefore the channel so as to bypass a portion of the channel deviation.
- La surface transversale de l'organe de réduction de débit est sensiblement plane et le fond de l'embout comprend des reliefs délimitant, avec la surface transversale de l'organe de réduction de débit, le canal de déviation du liquide. On peut donc modifier les reliefs du fond de l'embout pour définir avec la surface transversale de l'organe, un canal de section différente, d'une longueur différente et/ou d'une géométrie différente. On peut ainsi utiliser un organe de réduction de débit de forme simple.  - The transverse surface of the flow reduction member is substantially flat and the bottom of the nozzle comprises reliefs defining, with the transverse surface of the flow reduction member, the liquid deflection channel. It is therefore possible to modify the reliefs of the bottom of the mouthpiece to define with the transverse surface of the member, a channel of different section, of a different length and / or a different geometry. It is thus possible to use a flow reducing member of simple shape.
- L'organe de réduction de débit a la forme générale d'un disque. Il est délimité, par exemple, par deux surfaces transversales planes et une surface périphérique annulaire, en étant traversé par un canal de passage de liquide.  - The flow reduction device has the general shape of a disk. It is delimited, for example, by two flat transverse surfaces and an annular peripheral surface, through which is crossed by a liquid passage channel.
- La hauteur des reliefs dans la direction longitudinale est inférieure à 0,6 mm et de préférence comprise entre 0,05 et 0,5 mm.  - The height of the reliefs in the longitudinal direction is less than 0.6 mm and preferably between 0.05 and 0.5 mm.
- La hauteur de la base dans la direction longitudinale est supérieure à 0,6 mm et de préférence comprise entre 1 et 1 ,5 mm. - The height of the base in the longitudinal direction is greater than 0.6 mm and preferably between 1 and 1.5 mm.
- L'organe de réduction de débit comprend un canal essentiellement longitudinal de passage de liquide, dit canal d'alimentation, et le canal de déviation du liquide réalise une jonction entre le canal de sortie et le canal d'alimentation. Ce canal d'alimentation permet d'amener le liquide venant du réservoir jusqu'au canal de déviation du liquide.  - The flow reduction member comprises a substantially longitudinal liquid passage channel, said feed channel, and the liquid deflection channel makes a junction between the outlet channel and the feed channel. This supply channel makes it possible to bring the liquid coming from the reservoir to the channel of deflection of the liquid.
- Le canal d'alimentation est entièrement délimité par l'organe de réduction de débit. Ainsi, en étant intégralement délimité par une pièce, ses dimensions sont plus faciles à maîtriser que lorsqu'il est délimité par la jonction de deux pièces, ce qui pourrait être le cas lorsque le canal est délimité par une surface annulaire de l'organe de réduction de débit et une surface annulaire de l'embout. L'étanchéité annulaire entre la paroi annulaire de l'embout et la paroi annulaire de l'organe de réduction de débit est donc plus facile à garantir, et le canal d'alimentation a une section moins soumise aux tolérances de fabrication. Toutefois, on comprend que, de manière alternative, le canal d'alimentation peut être disposé sur la périphérie de l'organe, en étant délimité par une surface annulaire de l'embout.  - The supply channel is entirely delimited by the flow reduction device. Thus, being entirely delimited by a part, its dimensions are easier to control than when it is delimited by the junction of two parts, which could be the case when the channel is delimited by an annular surface of the body of flow reduction and an annular surface of the mouthpiece. The annular seal between the annular wall of the nozzle and the annular wall of the flow reduction member is therefore easier to guarantee, and the feed channel has a section less subject to manufacturing tolerances. However, it is understood that, alternatively, the feed channel may be disposed on the periphery of the member, being delimited by an annular surface of the tip.
- L'organe de réduction de débit est serré contre la surface transversale de l'embout dans la direction longitudinale, en étant fixé par exemple par encliquetage, par serrage ou par soudure par ultrason. L'organe est donc poussé contre le fond de l'embout dans la direction longitudinale et les reliefs sont en appui et de préférence légèrement écrasés contre le fond de l'embout ou de l'organe de réduction de débit, ce qui permet de garantir de façon encore plus fiable l'étanchéité entre les reliefs de l'organe ou de l'embout et le fond de l'embout ou de l'organe de réduction de débit, respectivement. Ainsi, on s'assure que le liquide parcourt l'intégralité du canal de déviation du liquide.  - The flow reduction member is clamped against the transverse surface of the nozzle in the longitudinal direction, being fixed for example by snapping, clamping or ultrasonic welding. The member is pushed against the bottom of the nozzle in the longitudinal direction and the reliefs are in abutment and preferably slightly crushed against the bottom of the tip or the flow reduction member, which ensures more reliably sealing between the reliefs of the member or the tip and the bottom of the tip or the flow reduction member, respectively. Thus, it is ensured that the liquid travels the entire liquid deflection channel.
- Le dispositif ne comporte que deux pièces : l'embout de distribution et l'organe de réduction de débit. On a donc un dispositif très simple à mettre en œuvre.  - The device has only two parts: the dispensing nozzle and the flow reduction member. So we have a very simple device to implement.
- L'organe de réduction de débit comprend une paroi d'obturation du canal de sortie, mobile élastiquement entre une configuration de repos, dans laquelle le liquide peut passer, et une configuration déformée, dans laquelle la paroi est plaquée contre le canal de sortie pour l'obturer. Ainsi, si l'utilisateur appuie de manière trop brusque et/ou trop forte sur le réservoir pour distribuer du liquide, l'augmentation brusque de la pression du liquide dans le réservoir va plaquer la paroi d'obturation en configuration déformée contre le canal de sortie et l'obturer au moins partiellement. Il ne pourra donc pas y avoir formation d'un jet de liquide. Lors d'une utilisation normale du dispositif en revanche, l'équilibre des pressions du liquide de chaque côté de l'organe de réduction de débit empêche la paroi d'obturation de prendre sa configuration déformée et le liquide peut passer du canal de déviation du liquide vers le canal de sortie du liquide. L'obturation du canal de sortie peut bien sûr être totale. - The flow reduction member comprises a closure wall of the outlet channel, elastically movable between a rest configuration, in which the liquid can pass, and a deformed configuration, in which the wall is pressed against the outlet channel to seal it. Thus, if the user presses the tank too sharply and / or too strongly to dispense liquid, the sudden increase in the pressure of the liquid in the tank will press the shutter wall in a deformed configuration against the exit and seal it at least partially. There can therefore be no formation of a jet of liquid. In normal use of the device, however, the pressure balance of the fluid on either side of the flow reduction member prevents the closure wall from taking its deformed configuration and the liquid can pass from the liquid deflection channel to the liquid outlet channel. The shutter of the output channel can of course be total.
- La paroi d'obturation est reliée à une base de l'organe de réduction de débit, par une paroi déformable, cette paroi déformable présentant une épaisseur faible par rapport à l'épaisseur de la base. L'épaisseur faible de la paroi déformable assure la mobilité de la paroi d'obturation entre les configurations de repos et déformée tout en permettant de réaliser l'organe de réduction de débit en une seule pièce.  - The closure wall is connected to a base of the flow reduction member by a deformable wall, this deformable wall having a small thickness relative to the thickness of the base. The small thickness of the deformable wall ensures the mobility of the closure wall between the rest configurations and deformed while allowing to realize the flow reduction member in one piece.
- Le dispositif est rapporté sur un réservoir, et l'embout de distribution monté étanche sur le réservoir.  - The device is attached to a tank, and the dispensing tip mounted tightly on the tank.
- L'embout est moulé en une seule pièce.  - The tip is molded in one piece.
- L'organe de réduction de débit est moulé en une seule pièce.  - The flow reduction member is molded in one piece.
- L'organe de réduction de débit est réalisé dans un matériau souple, par exemple un matériau élastomère. Ainsi, l'organe de réduction s'adapte avantageusement aux jeux dimensionnels et/ou aux irrégularités de surface pouvant être présents, permettant ainsi d'améliorer l'étanchéité entre l'organe de réduction de débit et l'embout.  - The flow reduction member is made of a flexible material, for example an elastomeric material. Thus, the reduction member advantageously adapts to dimensional clearances and / or surface irregularities that may be present, thereby improving the seal between the flow reduction member and the tip.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels :  The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:

- la figure 7 est une vue schématique en perspective de l'organe de réduction de débit du mode de réalisation de la figure 6.  FIG. 7 is a schematic perspective view of the flow reduction device of the embodiment of FIG. 6.
On a représenté sur la figure 1 la partie supérieure du col 10 d'un réservoir contenant du liquide à distribuer. Dans cet exemple, ce liquide est un liquide pharmaceutique tel qu'un liquide ophtalmique, buccal ou auriculaire, qui peut comprendre des produits conservateurs.  FIG. 1 shows the upper part of the neck 10 of a reservoir containing liquid to be dispensed. In this example, this liquid is a pharmaceutical liquid such as an ophthalmic liquid, oral or ear, which may include preservatives.
Un dispositif de distribution de produit liquide est rapporté de façon étanche, par encliquetage dans cet exemple, sur le col 10 du réservoir. Le dispositif comprend un embout de distribution 20 et peut être coiffé, comme cela est représenté à la figure 1 , par un capuchon 12 vissé sur le col 10 du réservoir.  A liquid product dispensing device is sealingly attached, snap-fitting in this example, to the neck 10 of the reservoir. The device comprises a dispensing nozzle 20 and can be capped, as shown in Figure 1, by a cap 12 screwed on the neck 10 of the reservoir.
L'embout 20 comprend une cavité 22 délimitée par un fond 24 ayant une surface transversale sensiblement plane et une jupe annulaire insérée à l'intérieur du col 10 du réservoir. La cavité 22 est de forme sensiblement cylindrique. La surface transversale est traversée par un canal longitudinal de sortie du liquide 26. Ce canal de sortie 26 forme une buse de distribution de liquide par laquelle le liquide est délivré sous forme de gouttes. Ce canal 26 débouche, à son extrémité amont, sur le fond 24 de l'embout et, à son extrémité aval, sur un orifice de distribution du liquide 28, qui comprend souvent des moyens de formation de goutte, en étant évasé. Cet embout 20 est de préférence moulé d'une seule pièce, par exemple en polypropylène, en polyéthylène ou en matériau élastomère.  The tip 20 comprises a cavity 22 delimited by a bottom 24 having a substantially flat transverse surface and an annular skirt inserted inside the neck 10 of the tank. The cavity 22 is substantially cylindrical in shape. The transverse surface is traversed by a longitudinal outlet channel of the liquid 26. This outlet channel 26 forms a liquid dispensing nozzle through which the liquid is delivered in the form of drops. This channel 26 opens, at its upstream end, on the bottom 24 of the nozzle and, at its downstream end, on a liquid dispensing orifice 28, which often comprises drop forming means, being flared. This tip 20 is preferably molded in one piece, for example polypropylene, polyethylene or elastomeric material.
On comprend que la direction longitudinale est définie comme la direction du canal de sortie 26 et que la direction transversale lui est perpendiculaire. Les références faites à l'amont et à l'aval se font en tenant compte du sens d'écoulement du liquide du réservoir vers l'orifice de distribution 28.  It will be understood that the longitudinal direction is defined as the direction of the outlet channel 26 and that the transverse direction is perpendicular to it. The references made upstream and downstream are made taking into account the direction of flow of the liquid from the reservoir to the dispensing orifice 28.
Outre l'embout 20, le dispositif de distribution de liquide comprend un organe de réduction de débit 30 ayant la forme générale d'un disque. Cet organe 30 est rapporté dans la cavité 22 de l'embout 20. On notera que le dispositif ne comporte ici que deux pièces : l'embout de distribution 20 et l'organe de réduction de débit 30.  In addition to the tip 20, the liquid dispensing device includes a flow reduction member 30 having the general shape of a disk. This member 30 is mounted in the cavity 22 of the nozzle 20. Note that the device here comprises only two parts: the dispensing nozzle 20 and the flow reduction member 30.
L'organe 30 comporte une base 32 dont la surface transversale avale 34 comprend des reliefs 36. Ces reliefs 36 sont venus de moulage avec la base 32. Cette base 32 a une fonction de support et porte les reliefs 36. Elle permet également de rigidifier l'organe 30.  The member 30 comprises a base 32 whose transverse surface swallows 34 comprises reliefs 36. These reliefs 36 are integrally molded with the base 32. This base 32 has a support function and carries the reliefs 36. It also makes it possible to stiffen the organ 30.
Dans ce mode de réalisation, la hauteur de la base 32 dans la direction longitudinale est supérieure à la hauteur des reliefs 36. Par exemple, la hauteur des reliefs est inférieure à 0,6 mm, en étant de préférence comprise entre 0,05 et 0,5 mm et la hauteur de la base est supérieure à 0,6 mm, en tant de préférence comprise entre 1 et 1 ,5 mm. In this embodiment, the height of the base 32 in the longitudinal direction is greater than the height of the reliefs 36. For example, the height of the reliefs is less than 0.6 mm, preferably between 0.05 and 0.5 mm and the height of the base is greater than 0.6 mm, preferably between 1 and 1.5 mm.
L'organe 30 comprend également un canal longitudinal de passage de liquide, dit canal d'alimentation 40, visible sur la figure 2B. Ce canal d'alimentation 40 traverse l'organe de réduction de débit 30 de part en part. Il permet au liquide contenu dans le réservoir de traverser l'organe 30 pour atteindre la surface transversale 34 de l'embout. On notera que le canal d'alimentation 40 est entièrement délimité par l'organe de réduction de débit 30. En particulier, le canal d'alimentation 40 n'est pas porté par une surface annulaire 48 de l'organe de réduction de débit 30, et n'est donc pas délimité en partie par une surface annulaire 50 de l'embout. L'étanchéité annulaire entre la paroi annulaire 50 de l'embout 20 et la paroi annulaire 48 de l'organe de réduction de débit 30 et la dimension du canal 40 sont donc plus faciles à garantir.  The member 30 also comprises a longitudinal liquid passage channel, said feed channel 40, visible in Figure 2B. This supply channel 40 passes through the flow reduction member 30 from one side to the other. It allows the liquid contained in the reservoir to pass through the member 30 to reach the transverse surface 34 of the nozzle. It will be noted that the feed channel 40 is entirely delimited by the flow reduction member 30. In particular, the feed channel 40 is not carried by an annular surface 48 of the flow reduction member 30 , and is therefore not delimited in part by an annular surface 50 of the tip. The annular seal between the annular wall 50 of the nozzle 20 and the annular wall 48 of the flow reduction member 30 and the dimension of the channel 40 are therefore easier to guarantee.
Toutefois, ce canal d'alimentation 40 peut être délimité par les surfaces annulaires 48 de l'organe de réduction de débit et 50 de l'embout.  However, this feed channel 40 may be delimited by the annular surfaces 48 of the flow reduction member and 50 of the nozzle.
L'organe 30 est de préférence moulé en une seule pièce, par exemple en polypropylène, en polyéthylène ou en matériau élastomère.  The member 30 is preferably molded in one piece, for example polypropylene, polyethylene or elastomeric material.
Dans le mode de réalisation présenté à la figure 1 , l'embout 20 comporte un bourrelet 42 circulaire qui permet de serrer l'organe 30 contre le fond 24 de l'embout et de fixer l'organe 30 dans cette position, par encliquetage. Ainsi, les reliefs 36 sont plaqués contre la surface transversale du fond 24 de l'embout et, dans cet exemple, légèrement déformés par compression, de façon à garantir l'étanchéité. Ces reliefs 36 délimitent, avec le fond 24, un canal de déviation du liquide 38. Ce canal de déviation du liquide 38 réalise une jonction entre le canal d'alimentation 40 et le canal de sortie 26.  In the embodiment shown in Figure 1, the tip 20 comprises a circular bead 42 which allows to clamp the member 30 against the bottom 24 of the nozzle and to fix the member 30 in this position, snap. Thus, the reliefs 36 are pressed against the transverse surface of the bottom 24 of the nozzle and, in this example, slightly deformed by compression, so as to ensure sealing. These reliefs 36 delimit, with the bottom 24, a liquid deflection channel 38. This liquid deflection channel 38 makes a junction between the supply channel 40 and the outlet channel 26.
Comme on peut le voir sur les diverses figures, le canal 38 s'étend dans un plan transversal, c'est-à-dire que la génératrice de ce canal 38 se trouve dans un plan transversal.  As can be seen in the various figures, the channel 38 extends in a transverse plane, that is to say that the generator of this channel 38 is in a transverse plane.
Le canal de déviation du liquide 38 représenté sur les figures 2A et 2B est non rectiligne, c'est-à-dire que le chemin que le liquide doit parcourir pour aller du canal d'alimentation 40 au canal de sortie 26 n'est pas droit. En effet, tout en restant dans un plan transversal, le canal 38 a une forme générale de spirale « carrée ». Ainsi, ce canal 38 est formé par une succession de segments.  The liquid deflection channel 38 shown in FIGS. 2A and 2B is non-rectilinear, that is to say that the path that the liquid must travel from the supply channel 40 to the outlet channel 26 is not law. Indeed, while remaining in a transverse plane, the channel 38 has a general shape of "square" spiral. Thus, this channel 38 is formed by a succession of segments.
Grâce à la rigidité conférée par la base 32, lors du serrage de l'organe 30 contre la surface transversale 24 de l'embout, on garantit que les reliefs 36 viennent en contact étanche avec le fond 24 et que le liquide est obligé de parcourir l'intégralité du canal de déviation du liquide 38, entre le canal d'alimentation 40 et le canal de sortie 26. On voit que la base 32 peut, en outre, comprendre un renfort 52, dans sa partie centrale, venu de moulage avec l'organe 30. Dans le cas présent, ce renfort 52 a la forme générale d'une croix et ce, afin de limiter la matière supplémentaire à mouler tout en garantissant une très bonne rigidité de l'organe. Thanks to the rigidity conferred by the base 32, during the clamping of the member 30 against the transverse surface 24 of the nozzle, it is ensured that the reliefs 36 come into sealing contact with the bottom 24 and that the liquid is obliged to traverse the entire liquid deflection channel 38, between the supply channel 40 and the channel of 26. It can be seen that the base 32 may also comprise a reinforcement 52, in its central part, integrally molded with the member 30. In the present case, this reinforcement 52 has the general shape of a cross and this, to limit the additional material to be molded while ensuring a very good rigidity of the body.
Selon un deuxième mode de réalisation présenté aux figures 3, 4A et 4B, le canal 38 peut être formé par une spirale circulaire.  According to a second embodiment shown in FIGS. 3, 4A and 4B, the channel 38 may be formed by a circular spiral.
Dans ce mode de réalisation, l'organe de réduction de débit 30 comprend, en outre, une paroi 44 d'obturation du canal de sortie 26. Cette paroi d'obturation 44 a la forme essentiellement d'un disque et est reliée à la base 32 de l'organe 30 par une paroi déformable 46, correspondant ici à une striction d'épaisseur. Cette paroi déformable 46 a la forme d'un anneau et présente une épaisseur faible par rapport à l'épaisseur de la base 32, c'est-à-dire par rapport à la hauteur dans la direction longitudinale de la base 32. Toutes ces parties de l'organe 30 sont venues de moulage entre elles et l'organe 30 peut être moulé d'une seule pièce.  In this embodiment, the flow reduction member 30 further comprises a wall 44 for closing the outlet channel 26. This closure wall 44 has the shape essentially of a disc and is connected to the base 32 of the member 30 by a deformable wall 46, here corresponding to a necking thickness. This deformable wall 46 has the shape of a ring and has a small thickness relative to the thickness of the base 32, that is to say with respect to the height in the longitudinal direction of the base 32. Parts of the member 30 are molded together and the member 30 can be molded in one piece.
Grâce à cette paroi déformable 46, la paroi d'obturation 44 est mobile entre une configuration de repos, dans laquelle le liquide peut passer du canal de déviation du liquide 38 au canal de sortie 26, et une configuration déformée, dans laquelle la paroi d'obturation 44 est plaquée contre le canal de sortie 26 pour l'obturer, partiellement ou totalement .  With this deformable wall 46, the closure wall 44 is movable between a rest configuration, in which the liquid can pass from the liquid deflection channel 38 to the outlet channel 26, and a deformed configuration, in which the wall of the shutter 44 is pressed against the outlet channel 26 to seal, partially or completely.
Ainsi, si l'utilisateur appuie de manière trop brusque et/ou trop forte sur le réservoir pour distribuer du liquide, l'augmentation brusque de la pression du liquide dans le réservoir va plaquer la paroi d'obturation 44 en configuration déformée contre le canal de sortie 26 et l'obturer au moins partiellement. Il ne pourra donc pas y avoir formation d'un jet de liquide.  Thus, if the user presses too sharply and / or too strongly on the tank to dispense liquid, the sudden increase in the pressure of the liquid in the tank will press the closure wall 44 in a deformed configuration against the channel output 26 and close at least partially. There can therefore be no formation of a jet of liquid.
Lors d'une utilisation normale du dispositif, l'équilibre des pressions du liquide de chaque côté de l'organe de réduction de débit 30 maintient la paroi d'obturation 44 en configuration non-déformée ou peu déformée et le liquide peut passer du canal de déviation du liquide 38 vers le canal de sortie du liquide 26.  During normal use of the device, the equilibrium of the liquid pressures on each side of the flow reduction member 30 keeps the closure wall 44 in an undistorted or slightly deformed configuration and the liquid can pass from the channel diverting the liquid 38 towards the outlet channel of the liquid 26.
On notera que sur la figure 3, la base 32 de l'organe de réduction du débit 30 est de forme annulaire, plus précisément de forme torique. Tout comme dans le mode de réalisation précédent, cette base 32, qui porte les reliefs 36, a une hauteur dans la direction longitudinale qui est supérieure à la hauteur des reliefs 36 dans cette même direction. On garantit ainsi que les reliefs 36 sont convenablement serrés contre le fond 24 de l'embout 20. En outre, dans cet exemple, l'organe de réduction de débit 30 est fixé sur l'embout 20 par soudure par ultrason. Toutefois tout autre mode de fixation, tel que l'encliquetage ou le serrage, peut être envisagé. La figure 5 présente un troisième mode de réalisation de l'organe de réduction de débit 30. Cet organe comprend deux canaux d'alimentation 40' et 40" ainsi que deux canaux de déviation du liquide 38' et 38". Ces deux canaux ont un tronçon commun 38"'. Aussi, chaque canal 38' et 38" réalise une jonction entre chaque canal d'alimentation 40' et 40", respectivement, et le canal de sortie 26 localisé au droit du centre de l'organe de réduction de débit 30. Les flèches représentent le sens de circulation du liquide. It will be noted that in FIG. 3, the base 32 of the flow reduction member 30 is of annular shape, more precisely of toric shape. As in the previous embodiment, this base 32, which carries the reliefs 36, has a height in the longitudinal direction which is greater than the height of the reliefs 36 in the same direction. This ensures that the reliefs 36 are properly tightened against the bottom 24 of the nozzle 20. In addition, in this example, the flow reduction member 30 is fixed on the tip 20 by ultrasonic welding. However any other method of attachment, such as snapping or tightening, may be considered. Figure 5 shows a third embodiment of the flow reduction member 30. This member comprises two supply channels 40 'and 40 "and two liquid deflection channels 38' and 38". These two channels have a common section 38 ".Also, each channel 38 'and 38" provides a junction between each supply channel 40' and 40 ", respectively, and the outlet channel 26 located at the center of the channel. The flow restrictor 30. The arrows represent the flow direction of the liquid.
Comme on peut le voir sur la figure 5, chaque canal 38', 38" comprend une pluralité de segments non alignés. Plus précisément, chaque canal de déviation du liquide 38', 38" comprend 5 segments, dont un segment commun 38"'. Le premier et le deuxième segment forment un angle d'environ 45°, le deuxième et le troisième segment forment un angle d'environ 45° également, le troisième et le quatrième segment forment un angle d'environ 90° et le quatrième et le cinquième segment forment un angle d'environ 60°.  As can be seen in Figure 5, each channel 38 ', 38 "comprises a plurality of non-aligned segments, specifically, each liquid deflection channel 38', 38" comprises 5 segments, including a common segment 38 "'. The first and second segments form an angle of approximately 45 °, the second and third segments form an angle of approximately 45 °, the third and fourth segments form an angle of approximately 90 °, and the fourth and the fifth segment form an angle of about 60 °.
Grâce à ces canaux de déviation du liquide 38' et 38", on crée, au sein du liquide, des points où l'écoulement du liquide est perturbé ce qui permet d'augmenter les pertes de charge de cet écoulement.  Through these liquid deflection channels 38 'and 38 ", there are created in the liquid, points where the flow of the liquid is disturbed thereby increasing the pressure losses of this flow.
Il est bien entendu que ces canaux peuvent comporter plus ou moins de segments, un nombre différent de canaux et/ou des angles entre chaque segment.  It is understood that these channels may comprise more or fewer segments, a different number of channels and / or angles between each segment.
Les figures 6 et 7 présentent un quatrième mode de réalisation dans lequel les éléments analogues à ceux des autres modes de réalisation sont identifiés par les mêmes références numériques.  Figures 6 and 7 show a fourth embodiment in which elements similar to those of the other embodiments are identified by the same reference numerals.
Ce mode de réalisation diffère des modes précédents en ce que le fond 24 de l'embout de distribution 20 comprend des reliefs 54 venus de moulage avec l'embout et l'organe de réduction de débit 30 comporte une base 32 ayant la forme d'un disque.  This embodiment differs from the previous modes in that the bottom 24 of the dispensing nozzle 20 comprises reliefs 54 integrally molded with the nozzle and the flow reduction member 30 comprises a base 32 having the shape of a disk.
Dans ce mode de réalisation, l'embout 20 comporte, par exemple, un bourrelet 42 circulaire qui permet de serrer l'organe 30 contre le fond 24 de l'embout comportant les reliefs 56 et de fixer l'organe 30 dans cette position, par encliquetage. Ainsi, les reliefs 56 sont plaqués contre la surface transversale 34 de l'organe de réduction de débit 30, et déforment légèrement par compression la surface transversale 34 de l'organe de réduction de débit, de façon à garantir l'étanchéité. Ces reliefs 56 délimitent, avec la surface 34, le canal de déviation du liquide 38.  In this embodiment, the end piece 20 comprises, for example, a circular bead 42 which makes it possible to tighten the member 30 against the bottom 24 of the endpiece comprising the reliefs 56 and to fix the member 30 in this position, by snapping. Thus, the reliefs 56 are pressed against the transverse surface 34 of the flow reduction member 30, and deform slightly by compression the transverse surface 34 of the flow reduction member, so as to ensure sealing. These reliefs 56 delimit, with the surface 34, the channel of deflection of the liquid 38.
On constate que l'organe de réduction de débit 30 est une pièce très simple à réaliser, à savoir un disque comprenant un canal transversal d'alimentation 40.  It can be seen that the flow reduction member 30 is a very simple piece to produce, namely a disc comprising a transverse feed channel 40.
En outre, dans ce mode de réalisation, comme dans les autres modes de réalisation, l'organe de réduction de débit 30 peut être avantageusement réalisé dans un matériau souple, par exemple un matériau élastomère. Ainsi, l'organe de réduction de débit 30 s'adapte aux jeux dimensionnels et/ou aux irrégularités de surface de l'embout 20 pouvant être présents, permettant ainsi d'améliorer l'étanchéité entre l'organe de réduction de débit 30 et l'embout 20. In addition, in this embodiment, as in the other modes of embodiment, the flow reduction member 30 may advantageously be made of a flexible material, for example an elastomeric material. Thus, the flow reduction member 30 is adapted to the dimensional clearances and / or surface irregularities of the nozzle 20 that may be present, thus making it possible to improve the seal between the flow reduction member 30 and the tip 20.
On notera enfin que l'invention n'est pas limitée aux modes de réalisation précédemment décrits. Notamment, le canal de déviation du liquide 38 peut prendre d'autres formes que celles précédemment décrites, la paroi obturatrice 44 peut être combinée à d'autres formes de canal que le canal en spirale 38 et le mode de fixation de l'organe de réduction de débit 30 n'est pas associé au seul mode de réalisation de l'organe qui a été présenté dans la description ci-dessus. Selon un exemple parmi beaucoup de possibilités, un organe de réduction de débit 30 comprenant un canal 38 en spirale peut être fixé sur l'embout 20 par encliquetage et ne pas comprendre de paroi d'obturation.  Finally, note that the invention is not limited to the embodiments described above. In particular, the deflection channel of the liquid 38 may take other forms than those previously described, the closure wall 44 may be combined with other channel shapes that the spiral channel 38 and the method of fixing the organ Reduction of flow rate is not associated with the single embodiment of the organ which has been presented in the description above. According to one of many possibilities, a flow reduction device 30 comprising a spiral channel 38 may be fixed on the tip 20 by snapping and do not include a closure wall.
