Description

Tête de pulvérisation pour dispositif de  Spray head for a device
distribution de produit fluide  fluid product distribution
La présente invention concerne une tête de pulvérisation pour dispositif de distribution de produit fluide.  The present invention relates to a spray head for fluid dispensing device.
Les têtes de pulvérisation pour dispositifs de distribution de produit fluide sont bien connues. Ces têtes comportent généralement plusieurs pièces, à savoir un corps formant la tête et une ou deux pièce(s) formant le gicleur, c'est-à-dire la partie qui crée la pulvérisation en faisant tourbillonner le produit fluide lorsqu'il est distribué. Dans le cas d'un gicleur externe, un petit manchon vient s'emmancher par l'extérieur dans l'extrémité aval de la tête pour définir avec celle-ci ledit profil de pulvérisation. Dans le cas d'un gicleur dit interne, c'est un insert inséré par l'intérieur de la tête qui vient coopérer avec la paroi d'extrémité de celle-ci pour définir le profil de pulvérisation. Dans les deux cas, les profils de pulvérisation comprennent généralement une pluralité de canaux non radiaux, notamment trois, formés soit dans la paroi de fond de la tête, soit sur le manchon formant gicleur externe, soit sur l'insert formant gicleur interne. Toutefois dans tous ces cas, la pulvérisation n'est réalisée que par la coopération de ces deux pièces, c'est-à-dire d'une part le gicleur externe avec la tête et d'autre part le gicleur interne avec la tête. Les têtes de pulvérisation existantes nécessitent un assemblage d'au moins une pièce dans une autre. Cet assemblage induit des différences de performance d'une tête de pulvérisation à l'autre. Ceci n'est pas toujours souhaitable. De même, le fait de réaliser les têtes avec deux ou trois pièces complique la fabrication et l'assemblage et rend celui-ci donc plus coûteux. Généralement, les têtes de pulvérisation sont assemblées sur les tiges de pistons ou des soupapes de valves pour guider le produit, qui est distribué hors de la pompe ou de la valve, vers l'orifice de pulvérisation. Toutefois, il a aussi été proposé de disposer une tête de pulvérisation directement sur la sortie d'un réservoir type seringue pour pulvériser le contenu de ladite seringue plutôt que de l'injecter à travers une aiguille. Le document WO 00/71263 décrit un tel arrangement. A nouveau, ces têtes de pulvérisation sont toujours réalisées avec deux ou plusieurs pièces assemblées les unes avec les autres. Les documents EP-1 475 157, FR-2 862 009 et WO 2007/012853 décrivent d'autres dispositifs de l'art antérieur. Spray heads for fluid dispensing devices are well known. These heads generally comprise several parts, namely a body forming the head and one or two part (s) forming the nozzle, that is to say the part that creates the spray by swirling the fluid when it is distributed . In the case of an external nozzle, a small sleeve is moved outwardly into the downstream end of the head to define therewith said spray profile. In the case of a so-called internal jet, it is an insert inserted through the inside of the head which cooperates with the end wall thereof to define the spray profile. In both cases, the spray patterns generally comprise a plurality of non-radial channels, including three, formed either in the bottom wall of the head, or on the outer nozzle sleeve, or on the inner nozzle insert. However in all these cases, the spraying is carried out only by the cooperation of these two parts, that is to say on the one hand the external nozzle with the head and on the other hand the inner nozzle with the head. Existing spray heads require an assembly of at least one part in another. This assembly induces differences in performance from one spray head to the other. This is not always desirable. Similarly, making heads with two or three parts complicates the manufacture and assembly and makes it more expensive. Generally, the spray heads are assembled on the piston rods or valve valves to guide the product, which is dispensed from the pump or valve, to the spray port. However, it has also been proposed to have a spray head directly on the outlet of a syringe-type reservoir for spraying the contents of said syringe rather than injecting it through a needle. WO 00/71263 describes such an arrangement. Again, these spray heads are always made with two or more parts assembled with each other. Documents EP-1 475 157, FR-2 862 009 and WO 2007/012853 describe other devices of the prior art.
La présente invention a pour but de fournir une tête de pulvérisation pour dispositif de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés.  The present invention aims to provide a spray head for fluid dispensing device that does not reproduce the aforementioned drawbacks.
La présente invention a aussi pour but de fournir une tête de pulvérisation pour dispositif de distribution de produit fluide qui soit simple et peu coûteuse à fabriquer et à assembler.  The present invention also aims to provide a spray head for fluid dispensing device that is simple and inexpensive to manufacture and assemble.
La présente invention a également pour but de fournir une telle tête de pulvérisation pour dispositif de distribution de produit fluide qui permet de réaliser une pulvérisation correcte et reproductible.  Another object of the present invention is to provide such a spray head for a fluid dispenser device which makes it possible to produce a correct and reproducible spray.
La présente invention a donc pour objet une tête de pulvérisation pour dispositif de distribution de produit fluide, comportant un corps creux comportant un manchon sensiblement cylindrique s'étendant le long d'un axe longitudinal, et une paroi de fond sensiblement radiale pourvue d'un orifice de pulvérisation, et un profil de pulvérisation en amont dudit orifice de pulvérisation, ledit profil de pulvérisation comportant au moins un canal non radial et/ou non axial par rapport audit axe longitudinal, ladite tête, ledit orifice de pulvérisation et ledit profil de pulvérisation étant réalisés sous la forme d'une seule pièce monobloc, ledit profil de pulvérisation comportant un plot central, l'extrémité interne dudit plot central, disposée à l'intérieur dudit corps creux, étant de forme conique ou tronconique, pour guider le produit fluide vers ledit au moins un canal non radial et/ou non axial, ladite extrémité interne formant un clapet de sortie.  The subject of the present invention is therefore a spray head for a fluid dispenser device, comprising a hollow body comprising a substantially cylindrical sleeve extending along a longitudinal axis, and a substantially radial bottom wall provided with a spray orifice, and a spray profile upstream of said spray orifice, said spray profile comprising at least one non-radial and / or non-axial channel relative to said longitudinal axis, said head, said spray orifice and said spray profile being made in the form of a single piece, said spray profile comprising a central stud, the inner end of said central stud, disposed inside said hollow body, being of conical or frustoconical shape, for guiding the fluid product. to said at least one non-radial and / or non-axial channel, said inner end forming an outlet valve.

Avantageusement, ledit profil de pulvérisation comporte au moins canal s'étendant de manière oblique et périphérique par rapport à l'axe longitudinal, reliant l'intérieur dudit corps creux audit orifice de pulvérisation. According to a second variant embodiment, said spray orifice is bowl-shaped symmetrical with respect to said longitudinal axis. Advantageously, said spray profile comprises at least one channel extending obliquely and circumferentially with respect to the longitudinal axis, connecting the interior of said hollow body to said spray orifice.
En variante, ledit profil de pulvérisation comporte au moins un canal hélicoïdal oblique en directions radiale et axiale, reliant l'intérieur dudit corps creux audit orifice de pulvérisation.  In a variant, said spray profile comprises at least one oblique helical channel in radial and axial directions, connecting the interior of said hollow body to said spray orifice.
Avantageusement, ledit plot central est relié audit manchon via une membrane monobloc déformable permettant un léger déplacement axial dudit plot central.  Advantageously, said central stud is connected to said sleeve via a deformable monobloc membrane allowing a slight axial displacement of said central stud.
La présente invention a aussi pour objet un dispositif de distribution de produit fluide, comportant un réservoir, des moyens de distribution du produit contenu dans ledit réservoir, et une tête de pulvérisation telle que décrite ci- dessus.  The present invention also relates to a fluid dispenser device comprising a reservoir, means for dispensing the product contained in said reservoir, and a spray head as described above.
Avantageusement, ledit réservoir est une seringue, et lesdits moyens de distribution comprennent un piston coulissant dans ladite seringue, ladite tête de pulvérisation étant assemblée directement sur ladite seringue.  Advantageously, said reservoir is a syringe, and said dispensing means comprise a piston sliding in said syringe, said spray head being assembled directly on said syringe.

Ces avantages et caractéristiques et d'autres de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante, faite en référence aux dessins joints, donnés à titre d'exemples non limitatifs, et sur lesquels  These and other advantages and features of the present invention will appear more clearly in the following detailed description, with reference to the accompanying drawings, given by way of non-limiting examples, and in which:
La figure 1 est une vue schématique en section transversale d'une tête de pulvérisation selon un mode de réalisation avantageux, assemblée sur un réservoir type seringue,  FIG. 1 is a schematic cross-sectional view of a spray head according to an advantageous embodiment, assembled on a syringe type tank,

La figure 3 est une vue schématique en section transversale de la tête de distribution du dispositif des figures 1 et 2, La figure 4 est une vue de dessus de la tête représentée sur la figure 3, FIG. 3 is a diagrammatic cross-sectional view of the dispensing head of the device of FIGS. 1 and 2, FIG. 4 is a view from above of the head represented in FIG. 3,
La figure 5 est une vue similaire à celle de la figure 3, représentant un autre mode de réalisation,  FIG. 5 is a view similar to that of FIG. 3, showing another embodiment,
La figure 6 est une vue de dessus de la tête représentée sur la figure 5,  FIG. 6 is a view from above of the head represented in FIG. 5,

La figure 8 est une vue de détail agrandie d'une partie du dispositif de la figure 7.  FIG. 8 is an enlarged detail view of part of the device of FIG. 7.
La présente invention sera décrite ci-après en référence à trois modes de réalisation différents de celle-ci, mais il est entendu que d'autres modes de réalisation pourraient être envisagés.  The present invention will be described hereinafter with reference to three different embodiments thereof, but it is understood that other embodiments could be envisaged.
En référence aux figures 1 à 4, il est représenté un premier mode de réalisation avantageux. La figure 1 représente une tête de pulvérisation 10 assemblée sur un réservoir 2 du type seringue. De manière classique, des moyens de distribution appropriés peuvent être prévus dans ladite seringue 2 pour distribuer le contenu de celle-ci. Typiquement, ces moyens de distribution comportent un piston solidaire d'une tige d'actionnement actionnée par l'utilisateur au moment de la distribution. Bien entendu, des moyens de distribution différents pourraient être envisagés, par exemple des moyens de distribution automatiques du type auto-injecteur. Néanmoins, ces moyens de distribution n'intervenant pas directement dans la présente invention, ils ne seront pas décrits plus en détail ci-après. De même, si la figure 1 représente une tête de distribution 10 assemblée directement sur un réservoir 2, cette tête de distribution pourrait également être assemblée sur un organe de distribution, tel qu'une pompe ou une valve, elle-même assemblée sur un réservoir.  With reference to FIGS. 1 to 4, there is shown a first advantageous embodiment. Figure 1 shows a spray head 10 assembled on a reservoir 2 of the syringe type. Conventionally, suitable dispensing means may be provided in said syringe 2 for dispensing the contents thereof. Typically, these dispensing means comprise a piston secured to an actuating rod actuated by the user at the time of dispensing. Of course, different distribution means could be envisaged, for example automatic dispensing means of the self-injector type. Nevertheless, these distribution means not directly involved in the present invention, they will not be described in more detail below. Similarly, if FIG. 1 represents a dispensing head 10 assembled directly on a tank 2, this dispensing head could also be assembled on a dispensing member, such as a pump or a valve, itself assembled on a reservoir. .
En se référant plus particulièrement à la figure 3, on constate que la tête de distribution 10 comporte un corps creux 1 1 comportant un orifice de pulvérisation 15. Ce corps creux 1 1 comporte avantageusement un manchon sensiblement cylindrique 12 qui se raccorde à une paroi de fond sensiblement radiale 13 qui comporte ledit orifice de pulvérisation 1 5, de préférence en son centre, donc sur l'axe longitudinal A dudit corps creux 1 1 . Par ailleurs, un profil de pulvérisation 20 est prévu, de préférence également au niveau de ladite paroi de fond 13. Referring more particularly to FIG. 3, it can be seen that the dispensing head 10 comprises a hollow body 1 1 comprising a spray orifice 15. This hollow body 1 1 advantageously comprises a substantially cylindrical sleeve 12 which connects to a wall of background substantially radial 13 which comprises said spray orifice 1 5, preferably at its center, therefore on the longitudinal axis A of said hollow body January 1. Furthermore, a spray profile 20 is provided, preferably also at said bottom wall 13.
Selon l'invention, ladite tête de distribution est réalisée d'une seule pièce monobloc. Ainsi, la pulvérisation du produit fluide est réalisée par une seule et même pièce, et il n'est pas nécessaire d'assembler un ou plusieurs pièces rapportées sur ou dans ladite tête pour réaliser cette pulvérisation.  According to the invention, said dispensing head is made of a single piece. Thus, the spraying of the fluid product is performed by one and the same piece, and it is not necessary to assemble one or more inserts on or in said head to perform this spraying.
Dans le mode de réalisation représenté sur les figures 1 à 4, le profil de pulvérisation 20 comporte au moins un canal s'étendant de manière oblique dans la direction axiale définie par l'axe longitudinal A du corps creux 1 1 . Comme visible sur la figure 4, il y a de préférence trois canaux de ce type répartis autour de l'axe longitudinal A. Ces canaux 25 s'étendent de manière périphérique par rapport audit axe longitudinal A et donc axialement de manière oblique dans ladite paroi de fond 13, pour relier l'intérieur du corps creux 1 1 audit orifice de pulvérisation 15. La forme périphérique, et donc partiellement circulaire, et oblique en direction axiale de ces canaux 25 provoque un tourbillonnement du produit fluide lorsqu'il va traverser lesdits canaux 25 au moment de son expulsion sous pression. Lorsque le produit parviendra dans l'orifice de pulvérisation 15, il aura donc un mouvement de tourbillonnement et sera donc distribué sous forme de spray. Dans l'exemple représenté sur la figure 3, l'orifice de pulvérisation 15 a une forme annulaire autour dudit axe longitudinal A. Cette forme annulaire favorise encore davantage le tourbillonnement du produit au moment de son expulsion.  In the embodiment shown in Figures 1 to 4, the spray pattern comprises at least one channel extending obliquely in the axial direction defined by the longitudinal axis A of the hollow body January 1. As can be seen in FIG. 4, there are preferably three channels of this type distributed around the longitudinal axis A. These channels 25 extend peripherally with respect to said longitudinal axis A and thus axially obliquely in said wall base 13, to connect the interior of the hollow body 1 1 to said spray orifice 15. The peripheral shape, and therefore partially circular, and oblique in the axial direction of these channels 25 causes a swirling of the fluid when it goes through said channels 25 at the time of its expulsion under pressure. When the product reaches the spray orifice 15, it will therefore have a swirling motion and will therefore be dispensed in the form of a spray. In the example shown in Figure 3, the spray orifice 15 has an annular shape about said longitudinal axis A. This annular shape further promotes the swirling of the product at the time of its expulsion.
Comme visible notamment sur la figure 3, le profil de pulvérisation 20 comporte un plot central 21 . Dans cette variante de réalisation, ce plot central définit par sa partie externe ladite forme annulaire de l'orifice de pulvérisation 15. Au niveau de son extrémité interne 22, qui est disposée à l'intérieur du corps creux 1 1 , ledit plot central 21 a une forme conique ou tronconique, qui sert notamment à guider le produit vers l'entrée desdits canaux 25. Ainsi, comme on le voit notamment sur la figure 2, lorsque la tête 10 est assemblée sur le réservoir 2, le produit qui est expulsé hors dudit réservoir 2 va être amené auxdits canaux de pulvérisation et ainsi être distribué sous forme de spray à travers l'orifice de pulvérisation 15. Il en serait bien entendu de même si la tête de distribution 10 était assemblée sur une tige de piston ou une soupape de valve. As can be seen in particular in FIG. 3, the spray profile 20 comprises a central stud 21. In this variant embodiment, this central stud defines, by its external part, said annular shape of the spray orifice 15. At its internal end 22, which is disposed inside the hollow body 1 1, said central stud 21 has a conical or frustoconical shape, which serves in particular to guide the product to the inlet of said channels 25. Thus, as seen in particular in Figure 2, when the head 10 is assembled on the tank 2, the product which is expelled out of said tank 2 will be brought to said spray channels and thus be dispensed as a spray through the spray orifice 15. It would of course be the same if the dispensing head 10 was assembled on a piston rod or a valve of valve.
Les figures 5 et 6 illustrent un autre mode de réalisation. Ce second mode de réalisation diffère du premier mode de réalisation des figures 1 à 4 principalement par la forme des canaux 25 et de l'orifice de pulvérisation 15. Ainsi, en se référant aux figures 5 et 6, on constate que l'orifice de pulvérisation 15 est ici réalisé sous la forme d'une cuvette sensiblement symétrique par rapport à l'axe longitudinal A et les canaux 25, de préférence également au nombre de trois, comportent des canaux hélicoïdaux obliques reliant l'intérieur du corps creux 1 1 audit orifice de pulvérisation 15. Dans cette variante, lesdits canaux 25 s'étendent donc de manière oblique non seulement dans la direction axiale mais également dans la direction radiale, puisqu'ils ne sont pas périphériques autour dudit axe longitudinal, mais au contraire hélicoïdaux, c'est-à-dire qu'ils se rapprochent progressivement dudit axe dans la direction radiale. A nouveau, cette forme particulière des canaux va permettre un tourbillonnement du produit fluide dans l'orifice de pulvérisation 15 au moment de sa distribution. Bien entendu, les canaux de ce second mode de réalisation pourraient être associé à un orifice de pulvérisation annulaire tel que représenté sur la figure 3. De même, l'orifice de pulvérisation en cuvette de la figure 5 pourrait être associé aux canaux du premier mode de réalisation des figures 1 à 4. Eventuellement, des canaux réalisés selon les deux modes de réalisation décrits ci-dessus pourraient être associés et/ou combinés.  Figures 5 and 6 illustrate another embodiment. This second embodiment differs from the first embodiment of FIGS. 1 to 4 mainly by the shape of the channels 25 and the spray orifice 15. Thus, with reference to FIGS. 5 and 6, it can be seen that the orifice of FIGS. sputtering 15 is here made in the form of a bowl substantially symmetrical with respect to the longitudinal axis A and the channels 25, preferably also three in number, comprise oblique helical channels connecting the interior of the hollow body 1 1 to said In this variant, said channels 25 thus extend obliquely not only in the axial direction but also in the radial direction, since they are not peripheral around said longitudinal axis, but instead helical, c that is, they move progressively closer to said axis in the radial direction. Again, this particular shape of the channels will allow a swirl of the fluid in the spray orifice 15 at the time of its distribution. Of course, the channels of this second embodiment could be associated with an annular spray orifice as shown in FIG. 3. Similarly, the bowl spray orifice of FIG. 5 could be associated with the channels of the first mode. embodiment of Figures 1 to 4. Optionally, channels made according to the two embodiments described above could be associated and / or combined.
Les figures 7 et 8 illustrent un mode de réalisation de la présente invention. Dans ce mode de réalisation, l'extrémité inférieure 22 du plot central 21 du profil de pulvérisation 20 forme clapet de sortie. Ainsi, comme on le voit sur la figure 8, cette extrémité inférieure coopère avec l'orifice de sortie du réservoir 2. Ainsi, en position de repos, qui est représentée sur la figure 8, ledit plot central 21 obture la sortie du réservoir 2. Au moment de l'expulsion du produit, ledit plot central 21 doit donc légèrement pouvoir se déformer, de préférence axialement, pour permettre l'expulsion du produit. Dans l'exemple représenté sur les figures 7 et 8, ledit plot central 21 , et plus généralement la paroi de fond 13 du corps creux 1 1 , est reliée au manchon 12 par une membrane 14 déformable. Ainsi, au moment de la distribution, c'est l'ensemble de la paroi de fond 13 qui va légèrement se déformer entraînant donc un déplacement axial du plot 21 et donc une ouverture du clapet de sortie 22. Dans l'exemple des figures 7 et 8, les canaux de pulvérisation 25 et l'orifice de pulvérisation 15 sont réalisés comme dans le mode de réalisation des figures 5 et 6, mais il est entendu qu'ils pourraient aussi être réalisés à la manière du premier mode de réalisation décrit en référence aux figures 1 à 4, voire différemment. Comme visible notamment sur la figure 8, la membrane 14 est réalisée d'une seule pièce monobloc avec le corps creux 1 1 de sorte que la tête de pulvérisation 10 est toujours réalisée d'une seule pièce monobloc. Avantageusement, cette membrane 14 est formée par des rétrécissements de parois créés par des évidements 19 formés dans la paroi de fond 13 du corps creux 1 1 . Ce mode de réalisation des figures 7 et 8 permet non seulement d'obturer la sortie de la seringue 2 au repos, mais aussi permet de créer un seuil de précompression. En effet, pour que le clapet s'ouvre, il faut qu'il y ait une pression prédéterminée dans la seringue. Ceci évite les risques d'expulsion à basse vitesse ou faible pression, qui peuvent affecter la qualité du spray. Pour que le liquide tourbillonne suffisamment pour former un spray, il doit avoir une pression suffisante lorsqu'il passe dans le profil de pulvérisation, et la présence de ce clapet permet de garantir cette pression minimale. Figures 7 and 8 illustrate an embodiment of the present invention. In this embodiment, the lower end 22 of the central stud 21 of the spray pattern 20 form outlet valve. Thus, as seen in FIG. 8, this lower end cooperates with the outlet orifice of the reservoir 2. Thus, in the rest position, which is represented in FIG. 8, said central stud 21 closes the outlet of the reservoir 2 At the time of the expulsion of the product, said central block 21 must therefore be able to slightly deform, preferably axially, to allow the expulsion of the product. In the example shown in Figures 7 and 8, said central stud 21, and more generally the bottom wall 13 of the hollow body 1 1, is connected to the sleeve 12 by a deformable membrane 14. Thus, at the time of dispensing, it is the entire bottom wall 13 which will slightly deform thereby causing axial displacement of the pad 21 and therefore an opening of the outlet valve 22. In the example of FIGS. and 8, the spray channels 25 and the spray orifice 15 are made as in the embodiment of Figures 5 and 6, but it is understood that they could also be made in the manner of the first embodiment described in reference to Figures 1 to 4, if not differently. As can be seen in particular in FIG. 8, the membrane 14 is made in one piece with the hollow body 1 1 so that the spray head 10 is always made in one piece. Advantageously, this membrane 14 is formed by wall narrowing created by recesses 19 formed in the bottom wall 13 of the hollow body 11. This embodiment of FIGS. 7 and 8 not only makes it possible to close the exit of the syringe 2 at rest, but also makes it possible to create a precompression threshold. Indeed, for the valve opens, there must be a predetermined pressure in the syringe. This avoids the risk of expulsion at low speed or low pressure, which can affect the quality of the spray. In order for the liquid to swirl sufficiently to form a spray, it must have sufficient pressure as it passes through the spray profile, and the presence of this valve makes it possible to guarantee this minimum pressure.
La présente invention fournit une tête de pulvérisation réalisée d'une seule pièce monobloc qui permet d'assurer une bonne pulvérisation du produit fluide à chaque actionnement. Par ailleurs, le fait que cette tête de pulvérisation soit d'une seule pièce et qu'il n'y a pas d'assemblage d'une pièce dans une autre, garantit que toutes les têtes de pulvérisation issues du même moule produiront sensiblement les mêmes performances, en supprimant les différences de performances liées à l'assemblage, comme cela est généralement le cas des têtes de pulvérisation comportant plusieurs pièces. Cette structure monobloc de la te permet aussi d'utiliser la seringue à la fois en mode expulsion et en mode aspiration, notamment de par l'absence de pièces mobiles et de ressorts dans la tête. The present invention provides a spraying head made in one piece piece which ensures a good spray fluid during each actuation. Moreover, the fact that this spray head is in one piece and that there is no assembly from one part to another, ensures that all the spray heads from the same mold will produce substantially the same. same performance, eliminating the differences in performance associated with the assembly, as is generally the case with spray heads with multiple rooms. This one-piece structure also allows you to use the syringe in both expulsion and suction mode, including the absence of moving parts and springs in the head.
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 modes de réalisation décrits et représentés sur les dessins, mais qu'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.
