Description

La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide contenant du produit fluide et avantageusement adapté à contenir également un gaz tel que de l'air, ledit réservoir comprenant une paroi d'actionnement déformable sur laquelle on appuie pour diminuer le volume interne du réservoir, et un orifice de distribution par lequel le produit fluide est refoulé sous forme d'une pulvérisation avantageusement biphasique, par appui sur la paroi d'actionnement. Un distributeur de ce type est déjà connu du document FR 2 791 645. Dans ce document, le réservoir est formé à partir de deux feuilles souples déformables soudées ensemble sur leurs périphéries et maintenant entre elles une pièce de matière plastique définissant un orifice de sortie et supportant un élément de matière poreuse qui s'étend à l'intérieur du réservoir de manière à s'imbiber de produit fluide. Les deux feuilles souples forment chacune une paroi d'actionnement déformable. Ces deux parois d'actionnement déformables sont sollicitées en éloignement l'une de l'autre par des moyens élastiques qui se présentent sous la forme d'un ressort qui peut être placé à l'intérieur du réservoir mais également à l'extérieur du réservoir. Il est donc possible de rapprocher les deux parois d'actionnement l'une de l'autre contre l'action du ressort. Ce document incorpore une caractéristique très intéressante qui peut également être mise en oeuvre dans le cadre de la présente invention. En l'occurrence, l'orifice de distribution est obturé par un organe d'obturation amovible alors que le ressort est comprimé à son état maximum de sorte que le réservoir définit un volume minimum. Ceci assure une épaisseur minimum au distributeur de sorte qu'il peut être inclus dans des magazines ou brochures en tant qu'échantillon gratuit sous la forme d'un véritable distributeur pulvérisateur.The present invention relates to a fluid dispenser comprising a fluid reservoir containing fluid and advantageously adapted to also contain a gas such as air, said tank comprising a deformable actuating wall on which presses to decrease the internal volume of the reservoir, and a dispensing orifice by which the fluid product is discharged in the form of a spray advantageously biphasic, by pressing on the actuating wall. A distributor of this type is already known from document FR 2 791 645. In this document, the tank is formed from two deformable flexible sheets welded together on their peripheries and now between them a piece of plastic material defining an exit orifice and supporting an element of porous material that extends inside the tank so as to imbibe fluid product. The two flexible sheets each form a wall deformable actuation. These two deformable actuating walls are solicited by moving away from each other by elastic means present in the form of a spring that can be placed inside the tank but also outside the tank. It is therefore possible to bring the two actuating walls against each other against the action of the spring. This document incorporates a very interesting feature that can also be implemented in the context of the present invention. In this case, the orifice dispenser is closed off by a removable closure member while the spring is compressed to its maximum state so that the tank defines a minimum volume. This ensures a minimum thickness to the dispenser so that it can be included in magazines or brochures as a sample free in the form of a true sprayer dispenser.

Toutefois, du fait que le réservoir est formé à partir de deux feuilles souples déformables sollicitées par un ressort, il est difficile de garantir une esthétique parfaite au distributeur. En effet, le ressort a tendance à déformer les feuilles souples lorsque l'organe d'obturation amovible est en place, du fait qu'il est comprimé au maximum. Pour palier à ces désagréments esthétiques, il est préférable de revêtir ou d'envelopper le distributeur dans un habillage qui lui confère une esthétique supérieure.However, because the tank is formed from two sheets flexible deformable solicited by a spring, it is difficult to guarantee a perfect aesthetic to the distributor. Indeed, the spring tends to distort the flexible sheets when the removable closure member is in place, because is compressed to the maximum. To overcome these aesthetic inconveniences, it is it is preferable to coat or wrap the dispenser in a clothing that gives a superior aesthetic.

La présente invention a pour but de remédier à cet inconvénient de l'art antérieur en définissant un distributeur de produit fluide dont l'esthétique n'est pas affectée par la nature du matériau employé pour réaliser le réservoir et plus particulièrement sa ou ses parois d'actionnement déformables.The present invention aims to overcome this disadvantage of the art prior art by defining a fluid dispenser whose aesthetics are not not affected by the nature of the material used to make the tank and more particularly its deformable actuating wall (s).

Pour atteindre ce but, la présente invention propose que le réservoir comprenne une plaque de fond, une plaque intermédiaire définissant une ouverture, et une plaque de couverture intégrant la paroi d'actionnement, l'ouverture formée dans la plaque intermédiaire définissant avec la plaque de fond et la plaque de couverture le volume utile du réservoir. Contrairement au document précité de l'art antérieur, le réservoir n'est plus simplement formé à partir de deux feuilles souples soudées ensemble pour définir un volume interne servant de réservoir, mais bien au contraire, le volume utile du réservoir est formé par l'ouverture de la plaque intermédiaire qui est complétée par l'apposition de deux autres plaques, respectivement de fond et de couverture. La plaque intermédiaire est rigide ou au moins sensiblement rigide et les plaques de fond et de couverture peuvent être elles aussi rigides, mais elles peuvent également être souples. De préférence, la plaque de fond est rigide ou sensiblement rigide, et la plaque de couverture peut éventuellement être formée à partir d'une feuille souple déformable ou sensiblement déformable.To achieve this goal, the present invention proposes that the reservoir includes a bottom plate, an intermediate plate defining a opening, and a cover plate incorporating the actuating wall, the opening formed in the intermediate plate defining with the plate of bottom and cover plate the useful volume of the tank. Contrary to aforementioned document of the prior art, the reservoir is no longer simply formed to from two flexible sheets welded together to define an internal volume serving as a reservoir, but on the contrary, the useful volume of the reservoir is formed by the opening of the intermediate plate which is completed by the affixing of two other plates, respectively bottom and cover. The intermediate plate is rigid or at least substantially rigid and the plates bottom and cover may also be rigid, but they may also be flexible. Preferably, the bottom plate is rigid or substantially rigid, and the cover plate can optionally be formed to from a deformable or substantially deformable flexible sheet.

Avantageusement, chaque plaque présente une épaisseur de paroi inférieure à environ 1 mm. De préférence, c'est la plaque intermédiaire qui présente l'épaisseur la plus importante de manière à définir un volume utile de réservoir de taille suffisante. L'ouverture dans la plaque intermédiaire se présente sous la forme d'une découpe de forme simple ou complexe. Cette découpe définit un cylindre de hauteur très réduite, étant donné que la plaque intermédiaire ne fait environ qu'un millimètre. Les plaques de fond et de couverture ne font que fermer ce cylindre de manière à obtenir un réservoir de forme cylindrique. Advantageously, each plate has a wall thickness less than about 1 mm. Preferably, it is the intermediate plate which has the largest thickness so as to define a useful volume of tank of sufficient size. The opening in the intermediate plate is presented in the form of a cut of simple or complex shape. This cutting defines a cylinder of very reduced height, since the plate intermediate is only about one millimeter. The bottom plates and cover only close this cylinder so as to obtain a reservoir of cylindrical shape.

La paroi d'actionnement est intégrée dans la plaque de couverture, mais on peut également envisager d'intégrer cette paroi d'actionnement dans la plaque de fond. On peut également envisager de prévoir deux parois d'actionnement, une dans chaque plaque de fond et de couverture.The actuating wall is integrated into the cover plate, but we can also consider integrating this actuating wall into the plate background. It can also be envisaged to provide two actuating walls, one in each bottom plate and cover.

Avantageusement, la paroi d'actionnement est formée de manière monobloc avec la plaque de couverture. Cependant de préférence, la paroi d'actionnement est rapportée dans la plaque de couverture qui présente une fenêtre de réception pour recevoir un organe d'actionnement formant la paroi d'actionnement. Avec ce second mode de réalisation, il est possible de réaliser les plaques de fond, intermédiaire et de couverture par poinçonnage de simples plaques et de réaliser l'organe d'actionnement par un moulage de matière plastique déformable.Advantageously, the actuating wall is formed so monoblock with the cover plate. However, preferably, the wall actuation is reported in the cover plate which has a receiving window for receiving an actuating member forming the wall actuating. With this second embodiment, it is possible to realize the bottom plates, intermediate and blanket by punching simple plates and realize the actuating member by a material molding deformable plastic.

Selon une forme de réalisation avantageuse, la paroi d'actionnement comprend des moyens élastiques lui conférant une mémoire de forme qui la ramène en position de repos correspondant au volume maximal du réservoir. De préférence, les moyens élastiques comprennent une lame souple noyée dans l'épaisseur de la paroi d'actionnement. Ainsi, les moyens élastiques ne sont pas en contact du produit fluide contenu dans le réservoir de sorte qu'aucune interaction n'est possible entre la lame souple et le produit fluide. En outre, la lame souple n'est pas visible de l'extérieur ce qui confère un meilleur aspect esthétique à la paroi d'actionnement. De plus, la lame souple est parfaitement protégée à l'intérieur de l'épaisseur de la paroi d'actionnement.According to an advantageous embodiment, the actuating wall comprises elastic means conferring on it a shape memory which returns to the rest position corresponding to the maximum volume of the tank. Of preferably, the elastic means comprise a flexible blade embedded in the thickness of the actuating wall. Thus, the elastic means are not in contact with the fluid contained in the reservoir so that no interaction is possible between the flexible blade and the fluid product. In addition, the soft blade is not visible from the outside which gives a better appearance aesthetic to the actuating wall. In addition, the flexible blade is perfectly protected inside the thickness of the actuating wall.

Selon une autre caractéristique, le réservoir contient une pièce de matière poreuse apte à retenir du produit fluide.According to another characteristic, the tank contains a piece of material porous able to retain fluid product.

Selon un autre aspect de l'invention, l'orifice de distribution est formé dans la plaque de couverture. En variante, l'orifice de distribution est formé dans la plaque intermédiaire.According to another aspect of the invention, the dispensing orifice is formed in the cover plate. Alternatively, the dispensing orifice is formed in the intermediate plate.

D'autre part, l'orifice de distribution peut être pourvu d'un organe d'obturation étanche amovible obturant l'orifice avant la première utilisation et repositionnable sur l'orifice après utilisation. On the other hand, the dispensing orifice may be provided with an organ removable sealing plug obturates the orifice before the first use and repositionable on the orifice after use.

Selon une autre caractéristique intéressante, l'organe d'obturation est initialement soudé autour de l'orifice et comprend en outre un adhésif repositionnable adapté à adhérer de manière répétée autour de l'orifice. L'organe d'obturation procure ainsi une sécurité de premier usage en étant initialement soudé et procure également une fermeture étanche appropriée de sorte que le distributeur peut être réutilisé ultérieurement sans risque de fuite.According to another interesting characteristic, the shutter member is initially welded around the orifice and further comprises an adhesive repositionable adapted to adhere repeatedly around the orifice. The organ shutter thus provides first-use safety by being initially welded and also provides an appropriate seal so that the dispenser can be reused later without risk of leakage.

Selon un autre aspect, les plaques de fond, intermédiaire et de couverture sont empilées et fixées l'une à l'autre, avantageusement par soudage ou collage, autour de l'ouverture formée par la plaque intermédiaire.In another aspect, the bottom, middle and cover plates are stacked and fixed to one another, advantageously by welding or gluing, around the opening formed by the intermediate plate.

Comme dans le document précité de l'art antérieur, la paroi d'actionnement peut être aplatie avant la première utilisation de sorte que le réservoir ne contient sensiblement que du produit fluide, le distributeur présentant alors une épaisseur inférieure ou égale à environ 2 mm.As in the aforementioned document of the prior art, the wall the actuator can be flattened before the first use so that the tank contains substantially only fluid, the dispenser then having a thickness less than or equal to about 2 mm.

Selon une caractéristique qui peut être commune à tous les modes de réalisation, au moins une des plaques est souple.According to a characteristic that can be common to all modes of realization, at least one of the plates is flexible.

Selon un autre aspect, l'ouverture dans la plaque intermédiaire est ouverte sur un bord externe de la plaque.In another aspect, the opening in the intermediate plate is open on an outer edge of the plate.

Dans une autre forme de réalisation, les plaques de fond et de couverture sont partiellement fixées l'une à l'autre.In another embodiment, the bottom and cover plates are partially fixed to each other.

Dans une application avantageuse, le réservoir contient également un gaz, tel que de l'air, de sorte qu'un mélange biphasique de produit fluide et de gaz est distribué à la sortie de l'orifice de distribution.In an advantageous application, the tank also contains a gas, such as air, so that a biphasic mixture of fluid and gas is distributed at the outlet of the dispensing orifice.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemples non limitatifs deux modes de réalisation de l'invention.The invention will now be further described with reference to attached drawings giving as non-limiting examples two embodiments of the invention.

Dans les deux modes de réalisation, le distributeur comprend une plaque de fond 1, une plaque intermédiaire 2, une plaque de couverture 3, une paroi d'actionnement 36 et un orifice de distribution 32 ; 22. Les plaques 1, 2, 3 et la paroi d'actionnement 36 définissent ensemble un réservoir de produit fluide 13. Le distributeur comprend aussi une pièce de matière poreuse 4 qui est logée dans le réservoir 13. Optionnellement, le distributeur peut être pourvu d'un organe d'obturation étanche amovible 5 qui vient recouvrir de manière étanche l'orifice de distribution 22 ; 32.In both embodiments, the dispenser comprises a plate 1, an intermediate plate 2, a cover plate 3, a wall an actuator 36 and a dispensing orifice 32; 22. The plates 1, 2, 3 and the actuating wall 36 together define a fluid reservoir 13. The dispenser also comprises a piece of porous material 4 which is housed in tank 13. Optionally, the dispenser may be provided with an removable sealing cap 5 which sealingly covers the orifice distribution 22; 32.

Les modes de réalisation des figures 1 et 2 ne se différencient l'un de l'autre que par l'emplacement de l'orifice de distribution, à savoir au niveau de la plaque de couverture 3 pour l'orifice de distribution 32 de la figure 1 et au niveau de la plaque intermédiaire 2 pour l'orifice de distribution 22 de la figure 2. On peut bien évidemment envisager d'autre forme de réalisation, par exemple dans laquelle l'orifice de distribution est situé au niveau de la plaque de fond 1. Quoiqu'il en soit, il paraít avantageux de voir l'orifice de distribution ensemble avec la paroi d'actionnement 36.The embodiments of FIGS. 1 and 2 differ from each other the other only by the location of the dispensing orifice, namely at the level of the cover plate 3 for the dispensing orifice 32 of FIG. of the intermediate plate 2 for the dispensing orifice 22 of FIG. can obviously envisage another embodiment, for example in which the dispensing orifice is located at the bottom plate 1. Anyway, it seems advantageous to see the dispensing orifice together with the actuating wall 36.

La figure 3 montre les six pièces constitutives du distributeur selon la forme de réalisation de la figure 1 puisque l'orifice de distribution est réalisé au niveau de la plaque de couverture.Figure 3 shows the six component parts of the dispenser according to the embodiment of Figure 1 since the dispensing orifice is made at level of the cover plate.

Les plaques 1, 2 et 3 sont de préférence des plaques de matière plastique relativement rigide. Toutefois, la plaque de couverture 3 peut être une simple feuille souple qui sert en réalité d'opercule pour compléter le réservoir 13 formé par la plaque intermédiaire 2 et la plaque de fond 1. On peut éventuellement imaginer que la plaque de fond 1 soit également réalisée à partir d'une feuille souple déformable. Même la plaque intermédiaire 2 peut être déformable. Cependant, il est préférable qu'au moins une des trois plaques soit rigide ou sensiblement rigide pour conférer une certaine rigidité au distributeur. Dans la pratique, la plaque de fond 1 et la plaque intermédiaire 2 sont des plaques relativement rigides et la plaque de couverture 3 peut au choix être une plaque sensiblement rigide ou une feuille souple déformable.The plates 1, 2 and 3 are preferably plastic plates relatively rigid. However, the cover plate 3 can be a simple flexible sheet which is actually used as a seal for completing the formed reservoir 13 by the intermediate plate 2 and the bottom plate 1. One can possibly imagine that the bottom plate 1 is also made from a sheet flexible deformable. Even the intermediate plate 2 can be deformable. However, it is preferable that at least one of the three plates be rigid or substantially rigid to impart some rigidity to the dispenser. In the In practice, the bottom plate 1 and the intermediate plate 2 are plates relatively rigid and the cover plate 3 can be a plate substantially rigid or deformable flexible sheet.

Selon une autre caractéristique, l'épaisseur cumulée du distributeur est sensiblement égale ou inférieure à 2 mm de manière à pouvoir être inclus dans des magazines ou brochures. Ceci implique que chaque plaque présente une épaisseur de paroi inférieure à environ 1 mm. En pratique, c'est la plaque intermédiaire 2 qui présente la plus grande épaisseur, alors que les plaques de fond 1 et de couverture 3 peuvent présenter une épaisseur inférieure.According to another characteristic, the cumulative thickness of the distributor is substantially equal to or less than 2 mm so that it can be included in magazines or brochures. This implies that each plate has a wall thickness less than about 1 mm. In practice, it is the plate intermediate 2 which has the greatest thickness, whereas the bottom 1 and cover 3 may have a lower thickness.

En se référant maintenant plus particulièrement à la figure 3, on voit que la plaque de fond 1 est un simple élément rectangulaire très plat et plein, puisqu'il ne comporte aucune découpe ni ouverture. La plaque de fond 1 peut par exemple avoir les dimensions d'une carte de crédit conventionnelle avec une épaisseur inférieure à environ 1 mm. Elle peut être réalisée à partir de n'importe quel matériau approprié, comme du matériau plastique, du papier, du métal, ou un complexe de ceux-ci. De préférence, pour des raisons pratiques et de coût, la plaque de fond 1 est réalisée par poinçonnage d'une grande feuille de matière plastique sensiblement rigide.Referring now more particularly to Figure 3, it can be seen that the bottom plate 1 is a simple rectangular element very flat and full, since it has no cut or opening. The bottom plate 1 can for example having the dimensions of a conventional credit card with a thickness less than about 1 mm. It can be done from anywhere which appropriate material, such as plastic material, paper, metal, or a complex of these. Preferably, for practical and cost reasons, the bottom plate 1 is made by punching a large sheet of material substantially rigid plastic.

La plaque intermédiaire 2 présente avantageusement les mêmes dimensions que celles de la plaque de fond 1 ; cependant, elle peut présenter une épaisseur supérieure. La plaque intermédiaire 2 peut également être réalisée par poinçonnage d'une grande plaque de matière plastique sensiblement rigide. On peut également envisager d'autres matériaux comme ceux de la plaque de fond 1. La plaque intermédiaire 2 est découpée de manière à former une ouverture 21 que l'on peut décomposer ici en deux parties 23 et 24 qui ne forment ensemble qu'une seule et même ouverture. Sur les figures, l'ouverture 21 n'est pas ouverte sur un bord de la plaque, mais cela peut être envisagé. L'ouverture se présenterait alors sous la forme d'une échancrure plus ou moins profonde.The intermediate plate 2 advantageously has the same dimensions than those of the bottom plate 1; however, it may have a superior thickness. The intermediate plate 2 can also be made by punching a large substantially rigid plastic plate. We can also consider other materials like those of the bottom plate 1. The intermediate plate 2 is cut to form an opening 21 that we can break down here into two parts 23 and 24 that do not form together only one and the same opening. In the figures, the opening 21 is not open on one edge of the plate, but this can be considered. The opening is would then present in the form of an indentation more or less deep.

La plaque de couverture 3 présente avantageusement les mêmes dimensions que celles des plaques de fond 1 et intermédiaire 2. Cependant, elle peut présenter une épaisseur inférieure à celle de la plaque intermédiaire 2 et même de la plaque de fond 1, puisqu'elle peut être réalisée à partir d'une simple feuille souple déformable. Cependant, une plaque sensiblement rigide sera préférée. On peut par exemple réaliser la plaque de fond 1 et la plaque de couverture 3 à partir du même matériau en feuille. Dans le mode de réalisation représenté sur les figures 1, 3 et 4, la plaque de couverture 3 est également formée avec un orifice de distribution 32 qui traverse la plaque de couverture. Dans le mode de réalisation de la figure 2, l'orifice de distribution 22 est formé transversalement à travers la plaque intermédiaire 2 : l'orifice de distribution 22 qui définit un canal de sortie s'étend à partir de l'ouverture 21 jusqu'à la tranche externe de la plaque intermédiaire, comme on peut le voir sur la figure 2.The cover plate 3 advantageously presents the same dimensions than those of the bottom plates 1 and intermediate 2. However, it may have a thickness less than that of the intermediate plate 2 and even of the bottom plate 1, since it can be made from a simple flexible deformable sheet. However, a substantially rigid plate will be preferred. For example, it is possible to make the bottom plate 1 and the plate of cover 3 from the same sheet material. In the embodiment shown in Figures 1, 3 and 4, the cover plate 3 is also formed with a dispensing orifice 32 which passes through the cover plate. In the embodiment of Figure 2, the dispensing orifice 22 is formed transversely through the intermediate plate 2: the dispensing orifice 22 which defines an output channel extends from the opening 21 to the slice external of the intermediate plate, as can be seen in Figure 2.

Dans les deux modes de réalisation, la paroi d'actionnement déformable 36 est formée par un organe d'actionnement 35 qui forme un dôme définissant la paroi d'actionnement 36. Ce dôme est reçu dans un logement de réception 31 formé dans la plaque de couverture 3. L'organe d'actionnement 35 est ici une pièce séparée rapportée dans le logement de réception 31 de la plaque de recouvrement 3. On peut cependant imaginer que la paroi d'actionnement 36 soit formée de manière monobloc avec la plaque de recouvrement 3 de manière à obturer le logement de réception 31. Ceci peut être réalisé en prévoyant une épaisseur de paroi plus fine au niveau de la paroi d'actionnement 36. Cependant, dans ce cas, il n'est plus possible de réaliser la plaque de recouvrement 3 par poinçonnage d'une grande plaque de matière plastique plane. Il est alors nécessaire de réaliser la plaque de recouvrement 3 par une technique d'injection et de moulage. La formation de la paroi d'actionnement par un organe d'actionnement séparé est préféré pour des raisons de coût et pour des raisons pratiques afin de pouvoir réaliser la plaque de recouvrement par simple poinçonnage. Ainsi, l'organe d'actionnement 35 définit ce dôme d'actionnement 36 qui est bordé périphériquement par une collerette 37 qui vient se loger sous le bord du logement de réception 31. Cette collerette 37 vient également se loger dans la partie d'ouverture 23 de l'ouverture 21 pratiquée dans la plaque intermédiaire 2. La surface inférieure de la collerette 37 vient en appui sur la plaque de fond 1. Comme on peut le voir en référence aux figures 5 et 6, la surface inférieure de la collerette 37 est formée avec plusieurs rainures de passage 38 de sorte qu'un passage est créé même lorsque la collerette 37 est appliquée sur la plaque de fond 1.In both embodiments, the deformable actuating wall 36 is formed by an actuating member 35 which forms a dome defining the actuating wall 36. This dome is received in a receiving housing 31 formed in the cover plate 3. The actuating member 35 is here a separate piece reported in the receiving housing 31 of the plate of 3. However, it can be imagined that the actuating wall 36 is integrally formed with the cover plate 3 so as to close the receiving compartment 31. This can be achieved by providing a thinner wall thickness at the actuating wall 36. However, in this case, it is no longer possible to make the cover plate 3 by punching a large flat plastic plate. So he is necessary to make the cover plate 3 by an injection technique and molding. The formation of the actuating wall by an organ Separate actuation is preferred for cost reasons and for reasons of practical in order to be able to realize the cover plate by simple punching. Thus, the actuating member 35 defines this actuating dome 36 which is bordered peripherally by a collar 37 which is housed under the edge of the receiving housing 31. This flange 37 is also housed in the opening portion 23 of the opening 21 made in the plate intermediate 2. The lower surface of the flange 37 bears on the bottom plate 1. As can be seen with reference to FIGS. 5 and 6, the lower surface of the collar 37 is formed with a plurality of passage grooves 38 so that a passage is created even when the flange 37 is applied on the bottom plate 1.

La paroi d'actionnement 36 comprend des moyens élastiques qui lui confèrent une mémoire de forme qui la ramène dans une position de repos convexe. Dans cette position, le volume défini en dessous de la paroi d'actionnement est maximal. En appuyant sur la paroi d'actionnement, celle-ci est enfoncée de sorte que le volume défini en dessous est fortement diminué. En relâchant la pression sur la paroi d'actionnement, celle-ci revient dans sa forme initiale convexe du fait des moyens élastiques. Dans la forme de réalisation de la figure 1, qui correspond aux figures 5 et 6, ces moyens élastiques sont conférés directement par le matériau constitutif de l'organe d'actionnement qui possède des qualités élastiques de mémoire de forme. Un matériau thermoplastique est parfaitement approprié. En revanche, dans le mode de réalisation de la figure 2 qui correspond à la figure 7, ces moyens élastiques peuvent être complétés par une lame souple 361 qui est avantageusement noyée dans l'épaisseur de la paroi d'actionnement 36. La lame souple peut même s'étendre au niveau de la collerette 37 comme on peut le voir sur la figure 7. Du fait que la lame souple 361 est noyée à l'intérieur de la paroi d'actionnement 36, elle ne peut pas venir en contact du produit fluide à distribuer. En outre, elle est également protégée de l'extérieur. Cette lame souple noyée 361 procure ou améliore les caractéristiques élastiques de mémoire de forme de la paroi d'actionnement 36. Il est à noter que cette caractéristiques peut être mise en oeuvre dans n'importe quelle paroi d'actionnement déformable élastique indépendamment du fait que le distributeur est constitué à partir de trois plaques superposées. Cette caractéristique peut donc être protégée indépendamment.The actuating wall 36 comprises elastic means which give a shape memory that brings it back to a rest position convex. In this position, the defined volume below the wall actuation is maximal. By pressing on the actuating wall, this one is depressed so that the volume defined below is greatly reduced. In releasing the pressure on the actuating wall, it returns in its shape initial convex due to the elastic means. In the embodiment of the FIG. 1, which corresponds to FIGS. 5 and 6, these elastic means are conferred directly by the constituent material of the actuating member which has elastic qualities of shape memory. A thermoplastic material is perfectly appropriate. In contrast, in the embodiment of Figure 2 which corresponds to FIG. 7, these elastic means can be supplemented by a flexible blade 361 which is advantageously embedded in the thickness of the wall The flexible blade may even extend at the level of the flange 37 as can be seen in Figure 7. Because the flexible blade 361 is embedded inside the actuating wall 36, it can not come in contact with the fluid product to be dispensed. In addition, it is also protected from outside. This embedded soft blade 361 provides or improves the characteristics shape memory elastics of the actuating wall 36. It should be noted that this characteristics can be implemented in any wall deformable elastic actuation regardless of whether the dispenser consists of three superimposed plates. This characteristic can therefore to be protected independently.

Enfin, la pièce de matière poreuse 4 peut être réalisée à partir de n'importe quel matériau susceptible de s'imprégner d'un produit fluide. La forme de la pièce de matière poreuse 4 est avantageusement adaptée à la forme de la partie d'ouverture 24 de l'ouverture 21 formée à travers la plaque intermédiaire 2. En outre, la pièce de matière poreuse 4 est formée avec un évidement 41 dans lequel vient s'insérer la collerette 37 de l'organe d'actionnement 35. Ceci est clairement visible sur la figure 4 où l'on voit la plaque intermédiaire 2 montée en contact sur la plaque de fond 1 avec la pièce de matière poreuse 4 logée dans la partie d'ouverture 24 et l'organe d'actionnement 35 logé dans la partie d'ouverture 23 et dans l'évidement 41.Finally, the piece of porous material 4 can be made from any material likely to become impregnated with a fluid product. The form of the piece of porous material 4 is advantageously adapted to the shape of the opening portion 24 of the opening 21 formed through the intermediate plate 2. In addition, the piece of porous material 4 is formed with a recess 41 in which is inserted the flange 37 of the actuating member 35. This is clearly visible in Figure 4 where we see the intermediate plate 2 mounted in contact on the bottom plate 1 with the piece of porous material 4 housed in the opening part 24 and the actuating member 35 housed in the part 23 and in the recess 41.

L'organe d'obturation étanche amovible 5 se présente sous la forme d'une bande souple qui définit une partie de fixation permanente 51 fixée à la face inférieure de la plaque de fond 1, une partie d'obturation 52 recouvrant de manière étanche l'orifice de distribution 22 ; 32 et une languette de préhension 53 par laquelle l'utilisateur peut tirer la bande 5 afin de retirer la partie d'obturation 52 de l'orifice de distribution. Avantageusement, la partie d'obturation 52 est initialement soudée autour de l'orifice de distribution pour l'isoler de manière étanche. En outre, la partie d'obturation 52 est pourvue d'un adhésif repositionnable permettant d'obturer l'orifice de distribution ultérieurement après utilisation. On peut ainsi se servir plusieurs fois du distributeur sans risque de fuite par écoulement de produit à travers l'orifice de distribution. Il est à noter qu'une telle caractéristique, à savoir une languette d'obturation thernaoscellée et adhésive de manière repositionnable, peut être mise en oeuvre sur n'importe quel distributeur doté d'un orifice de distribution, indépendamment de la forme de réalisation en trois plaques empilées superposées décrites ici. Cette caractéristique est donc protégeable indépendamment.The removable sealing member 5 is in the form of a flexible strip which defines a permanent fastening portion 51 attached to the face lower part of the bottom plate 1, a sealing portion 52 covering sealingly the dispensing orifice 22; 32 and a gripping tab 53 by which the user can pull the tape 5 in order to remove the part shutter 52 of the dispensing orifice. Advantageously, the part shutter 52 is initially welded around the dispensing orifice for isolate it tightly. In addition, the closing portion 52 is provided with a repositionable adhesive for closing the dispensing orifice later after use. It is thus possible to use the dispenser without risk of leakage by product flow through the orifice of distribution. It should be noted that such a characteristic, namely a tongue sealing and repositionably adhesive sealing, can be implemented on any distributor having a dispensing orifice, regardless of the embodiment in three stacked plates superimposed described here. This characteristic is therefore protectable independently.

Selon l'invention, la plaque intermédiaire 2 avec son ouverture 21 est fixée sur la plaque de fond 1 le long d'une ligne de fixation étanche 19. Avantageusement, la technique utilisée pour la fixation de la plaque intermédiaire 2 sur la plaque de fond 1 est le thermosoudage. La plaque de fond 1 et la plaque intermédiaire 2 définissent alors ensemble un volume interne dont les parois périphériques sont formées par les bords de l'ouverture 21 et le fond de la plaque de fond 1. La pièce de matière poreuse 4 est placée dans l'ouverture 21 au niveau de la partie 24. De même, l'organe d'actionnement 35 est placé dans l'ouverture 24 au niveau de la partie 23. L'organe d'actionnement 35 est fixé, avantageusement par soudage, à la plaque de fond 1 le long d'une ligne de fixation 39 qui s'étend périphériquement sur la collerette 37. A ce stade, on est dans la configuration représentée sur la figure 4. Enfin, la plaque de couverture 3 est fixée de manière étanche sur la plaque intermédiaire 2 le long d'une ligne de fixation étanche 29, qui peut également être réalisée par thermosoudage. Le positionnement de la plaque de couverture 3 sur la plaque intermédiaire 2 entraíne l'engagement de la paroi d'actionnement en dôme 36 de l'organe d'actionnement 35 à travers le logement de réception 31 formé dans la plaque de recouvrement 3. La plaque de recouvrement 3 est également soudée à l'organe d'actionnement 35 au niveau de la ligne de fixation 39.According to the invention, the intermediate plate 2 with its opening 21 is fixed on the bottom plate 1 along a watertight fastening line 19. Advantageously, the technique used for fixing the plate intermediate 2 on the bottom plate 1 is the heat sealing. The bottom plate 1 and the intermediate plate 2 then together define an internal volume of which the peripheral walls are formed by the edges of the opening 21 and the bottom of the bottom plate 1. The piece of porous material 4 is placed in the opening 21 at the level of the portion 24. Similarly, the actuating member 35 is placed in the opening 24 at the portion 23. The actuating member 35 is fixed, advantageously by welding, to the bottom plate 1 along a line of fixation 39 which extends peripherally on the flange 37. At this stage, it is in the configuration shown in Figure 4. Finally, the cover plate 3 is sealingly attached to the intermediate plate 2 along a line of waterproof fastener 29, which can also be made by heat sealing. The positioning the cover plate 3 on the intermediate plate 2 entails the engagement of the dome actuating wall 36 of the body actuator 35 through the receiving housing 31 formed in the 3. The cover plate 3 is also welded to the body actuator 35 at the fastening line 39.

L'empilement des trois plaques 1, 2 et 3 et leur fixation mutuelle étanche avec l'organe d'actionnement 35 définit un réservoir 13 qui s'étend sur toute l'étendue de l'ouverture 21 de la plaque intermédiaire 2, c'est à dire aussi bien au niveau de la paroi d'actionnement 36 qu'au niveau de la pièce de matière poreuse 4. Comme on peut le voir sur les figures 1 et 2, la partie du réservoir définie au niveau de la paroi d'actionnement 36 communique avec la partie du réservoir définie au niveau de la pièce de matière poreuse 4 par les rainures de passage 38 formées sur la face inférieure de la collerette 37 de l'organe d'actionnement 35. Il est à noter que la pièce de matière poreuse 4 est située entre la paroi d'actionnement 36 et l'orifice de distribution 22 ou 32. De ce fait un écrasement de la paroi d'actionnement 36 a pour effet de réduire le volume interne du réservoir 13 et de chasser le produit fluide à travers la pièce de matière poreuse 4 pour être distribué sous forme pulvérisée au niveau de l'orifice de distribution. De préférence, le réservoir 13 contient une petite quantité de produit fluide et du gaz, par exemple de l'air. Le produit fluide peut par exemple être intégralement contenu à l'intérieur de la pièce de matière poreuse 4, alors que la partie du réservoir définie sous la paroi d'actionnement 36 peut être uniquement remplie d'air. En appuyant sur la paroi d'actionnement 36, cela a pour effet de chasser l'air contenu dans cette partie du réservoir à travers les nervures de passage 38 puis à travers la pièce de matière poreuse 4 qui est imbibée de produit fluide. Le mélange biphasique d'air et de produit fluide est alors distribué à travers l'orifice de distribution sous la forme d'un jet biphasique pulvérisé.The stacking of the three plates 1, 2 and 3 and their mutual secure fastening with the actuating member 35 defines a reservoir 13 which extends over any the extent of the opening 21 of the intermediate plate 2, ie both level of the actuating wall 36 at the level of the piece of material porous 4. As can be seen in Figures 1 and 2, the part of the tank defined at the level of the actuating wall 36 communicates with the portion of the tank defined at the porous material part 4 by the grooves of passage 38 formed on the underside of the flange 37 of the body It should be noted that the piece of porous material 4 is located between the actuating wall 36 and the dispensing orifice 22 or 32. crushing of the actuating wall 36 has the effect of reducing the volume internal tank 13 and to drive the fluid through the piece of material porous 4 to be distributed in spray form at the orifice of distribution. Preferably, the reservoir 13 contains a small amount of product fluid and gas, for example air. The fluid product may for example be completely contained within the piece of porous material 4, while the part of the tank defined under the actuating wall 36 can be only filled with air. By pressing on the actuating wall 36, this has the effect of chase the air contained in this part of the tank through the ribs of passage 38 then through the piece of porous material 4 which is impregnated with product fluid. The two-phase mixture of air and fluid is then distributed to through the dispensing orifice in the form of a sprayed two-phase jet.

Selon une autre caractéristique de l'invention, la paroi d'actionnement 36 est complètement enfoncée de manière à ramener la paroi 36 en contact de la plaque de fond 1 avant utilisation. L'obturation de l'orifice de distribution à l'aide de l'organe d'obturation 5 empêche la pénétration d'air à l'intérieur du réservoir 13 qui ne contient que ou pratiquement que du produit fluide. Ainsi, en condition de stockage avant utilisation, l'épaisseur du distributeur correspond à l'épaisseur cumulée des trois plaques de fond, intermédiaire et de recouvrement qui est avantageusement inférieure à environ 2 mm. Dès que l'on retire l'organe d'obturation amovible, de l'air peut pénétrer dans le réservoir et les moyens élastiques de la paroi d'actionnement 36 la ramènent dans la position de repos convexe représentée sur les figures 1 et 2. Après utilisation par enfoncement de la paroi d'actionnement 36, l'organe d'obturation peut être repositionné grâce à son adhésif approprié, ce qui est représenté sur les figures 1 et 2.According to another characteristic of the invention, the actuating wall 36 is completely depressed so as to bring the wall 36 into contact with the bottom plate 1 before use. Closing of the dispensing orifice at the aid of the shutter member 5 prevents the entry of air into the interior of the reservoir 13 which contains only or virtually only fluid product. So, in storage condition before use, the thickness of the dispenser corresponds to the cumulative thickness of the three bottom, intermediate and overlapping plates which is advantageously less than about 2 mm. As soon as we remove the organ removable shutter, air can enter the tank and the means resilient of the actuating wall 36 bring it back to the rest position convex shown in Figures 1 and 2. After use by depressing the actuating wall 36, the closure member can be repositioned by means of its adhesive, which is shown in Figures 1 and 2.

Dans un mode de réalisation envisageable, la plaque de couverture peut être reliée à la plaque de fond en certains endroits. Ceci peut notamment être le cas lorsque l'ouverture de la plaque intermédiaire débouche sur un bords de la plaque. A cet endroit, les plaques de couverture et de fond peuvent être soudées ensemble.In one conceivable embodiment, the cover plate can be connected to the bottom plate in some places. This can especially be the case when the opening of the intermediate plate opens on an edge of the plate. At this point, the cover and bottom plates can be welded together.

Grâce à l'invention, le distributeur de produit fluide présente une bonne tenue rigide, un aspect esthétique plan et lisse, une bonne fiabilité d'actionnement et une assurance contre les fuites.Thanks to the invention, the fluid dispenser has a good rigid hold, a flat and smooth aesthetic appearance, good reliability actuation and insurance against leaks.
