Description

La présente invention concerne un dispositif de produit fluide pulvérulent comprenant un réservoir de produit fluide pourvu d'une paroi d'actionnement déplaçable et d'un orifice de pulvérisation. Le terme pulvérulent désigne tout solide sous forme de fines particules telle qu'une poudre qui possède des qualités mécaniques et dynamiques des liquides, c'est-à-dire qu'il s'écoule, se pulvérise, remplit des volumes etc. La présente invention s'applique plus particulièrement au domaine de la parfumerie, de la cosmétique ou encore de la pharmacie.The present invention relates to a powdery fluid device comprising a fluid reservoir with a movable actuating wall and a spray port. The term "powder" refers to any solid in the form of fine particles such as a powder which has mechanical and dynamic qualities of the liquids, that is to say, it flows, pulverizes, fills volumes, etc. The present invention applies more particularly to the field of perfumery, cosmetics or pharmacy.

Pour l'actionnement du distributeur, il suffit d'exercer une pression sur la paroi d'actionnement déplaçable pour ainsi réduire le volume utile du réservoir et mettre le produit fluide pulvérulent qu'il contient sous pression. Sous l'effet de cette pression, le produit fluide pulvérulent est refoulé en direction de l'orifice de pulvérisation au-delà duquel il est distribué sous la forme d'un jet de produit pulvérisé. Il est avantageux que le réservoir contienne un gaz, par exemple de l'air, qui va servir de milieu d'entraînement pour transporter le produit fluide pulvérulent en direction de l'orifice de pulvérisation et au-delà sous forme pulvérisée.For the actuation of the dispenser, it is sufficient to exert pressure on the movable actuating wall to thereby reduce the useful volume of the reservoir and put the powdery fluid it contains under pressure. Under the effect of this pressure, the powdery fluid product is discharged towards the spray orifice beyond which it is dispensed in the form of a jet of sprayed product. It is advantageous for the reservoir to contain a gas, for example air, which will serve as a driving medium for transporting the pulverulent fluid in the direction of the spray orifice and beyond in spray form.

Pour garantir une distribution continue et sensiblement constante à la sortie de l'orifice de pulvérisation, il est nécessaire que la proportion de produit fluide pulvérulent par rapport au gaz soit environ constante. Or, le produit fluide pulvérulent peut se déplacer à l'intérieur du réservoir et s'accumuler d'un coté ou de l'autre en éloignement ou à proximité de l'orifice de pulvérisation. Ainsi, en fonction de la localisation du produit fluide pulvérulent à l'intérieur du réservoir, le jet de produit pulvérisé va être plus ou moins chargé en produit fluide pulvérulent.To ensure a continuous and substantially constant distribution at the outlet of the spray orifice, it is necessary that the proportion of fluid product powder with respect to the gas is approximately constant. However, the pulverulent fluid product can move inside the reservoir and accumulate on one side or the other away from or near the spray orifice. Thus, depending on the location of the powdery fluid product inside the tank, the jet of sprayed product will be more or less loaded powdery fluid product.

Dans l'art antérieur, le document US 2002/0190081 décrit un distributeur à paroi d'actionnement déformable comprenant un réservoir contenant du produit fluide qui peut être du type pulvérulent. Le réservoir contient également une pièce de matière poreuse apte à s'imprégner de produit fluide. Cette pièce de matière poreuse occupe une partie mineure du volume du réservoir, de sorte que du produit pulvérulent peut s'accumuler dans le réservoir hors de la pièce de matière poreuse. Ceci résulte en une inconstance de la pulvérisation.In the prior art, US 2002/0190081 discloses a deformable actuating wall dispenser comprising a reservoir containing fluid which may be of the powder type. The reservoir also contains a piece of porous material capable of impregnating fluid product. This piece of porous material occupies a minor part of the volume of the tank, so that powdery product can accumulate in the tank outside the porous material room. This results in an inconstancy of the spray.

La présente invention a pour but de résoudre ce problème lié à l'inconstance de la pulvérisation à la sortie de l'orifice de pulvérisation.The present invention aims to solve this problem related to the inconstancy of the spray at the outlet of the spray orifice.

Pour atteindre ce but, la présente invention propose que le réservoir contienne une pièce de matière poreuse, avantageusement à cellule interne ouverte, qui est apte à s'imprégner de gaz et de produit fluide pulvérulent, caractérisé en ce que la pièce de matière poreuse occupe la majeure partie du volume du réservoir. Ainsi, le produit fluide pulvérulent est réparti dans les cellules de manière pratiquement homogène spatialement à l'intérieur du réservoir. On évite ainsi toute accumulation de produit fluide pulvérulent à un endroit précis du réservoir. De plus, la pièce de matière poreuse fait office de labyrinthe pour le gaz et le produit fluide pulvérulent qu'il est amené à transporter. Les cellules ouvertes de la pièce de matière poreuse sont autant de voies de transport pour le produit fluide pulvérulent véhiculé par le gaz sous pression. Contrairement à un produit fluide liquide qui imbiberait la pièce de matière poreuse par un effet de capillarité, le produit fluide pulvérulent est supporté par les parois internes des cellules ouvertes constitutives de la pièce de matière poreuse, les empêchant ainsi de s'accumuler par l'effet de la gravité. En effet, le produit fluide pulvérulent n'est pas sensible à la capillarité. On ne se sert donc pas de la pièce de matière poreuse à la manière d'une éponge imbibante, mais au contraire pour supporter les fines particules constitutives du produit fluide pulvérulent de manière homogène dans la quasi totalité du réservoir pour créer une distribution spatiale régulière. La pièce de matière poreuse sert ainsi de moyen de support étagé pour le produit fluide pulvérulent qui est soumis à la gravité.To achieve this object, the present invention proposes that the reservoir contains a piece of porous material, advantageously an open internal cell, which is able to impregnate with gas and fluid powder, characterized in that the piece of porous material occupies most of the volume of the tank. Thus, the pulverulent fluid product is distributed in the cells in a substantially homogeneous manner spatially inside the reservoir. This avoids any accumulation of powdery fluid at a specific location in the tank. In addition, the piece of porous material acts as labyrinth for the gas and the powdery fluid that it is transported. The open cells of the piece of porous material are as many transport routes for the powdered fluid product conveyed by the gas under pressure. In contrast to a liquid fluid product which soaks the piece of porous material by a capillary effect, the powdery fluid product is supported by the inner walls of the open cells constituting the piece of porous material, thus preventing them from accumulating by the effect of gravity. Indeed, the powdery fluid product is not sensitive to capillarity. The piece of porous material is therefore not used in the manner of a soaking sponge, but on the contrary to support the fine particles constituting the pulverulent fluid product in a homogeneous manner in almost the entire reservoir to create a regular spatial distribution. The piece of porous material thus serves as a stepped support means for the pulverulent fluid product which is subjected to gravity.

Avantageusement, la pièce de matière poreuse s'étend jusqu'à proximité de l'orifice de pulvérisation. En variante, la pièce de matière poreuse peut être séparée de l'orifice de pulvérisation par une chambre de mélangeage.Advantageously, the piece of porous material extends to near the spray orifice. Alternatively, the piece of porous material may be separated from the spray orifice by a mixing chamber.

Selon une autre caractéristique, la pièce de matière poreuse peut être élastiquement déformable.According to another feature, the piece of porous material may be elastically deformable.

Avantageusement, la pièce de matière poreuse peut s'étendre sous la paroi d'actionnement de manière à être déformée lors du déplacement de la paroi d'actionnement. Dans ce cas, la pièce de matière poreuse peut solliciter élastiquement la paroi d'actionnement du réservoir vers une position de repos.Advantageously, the piece of porous material can extend under the actuating wall so as to be deformed during the displacement of the actuating wall. In this case, the piece of porous material can elastically urge the actuating wall of the reservoir to a rest position.

Selon une autre caractéristique de l'invention, la pièce de matière poreuse occupe sensiblement la totalité du volume de réservoir. En variante, la pièce de matière poreuse occupe plus de la moitié, avantageusement 60%, et de préférence 75% du volume du réservoir.According to another characteristic of the invention, the piece of porous material occupies substantially the entire reservoir volume. Alternatively, the piece of porous material occupies more than half, preferably 60%, and preferably 75% of the volume of the tank.

Selon une autre caractéristique de l'invention, sensiblement la totalité du produit fluide pulvérulent du réservoir est imprégnée dans la pièce de matière poreuse.According to another characteristic of the invention, substantially all the pulverulent fluid product of the reservoir is impregnated into the piece of porous material.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will now be more fully described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of the invention.

Sur les figures :

  • la figure 1 est une vue de dessus d'un distributeur de produit fluide selon l'invention,
  • la figure 2 est une vue en coupe transversale verticale à travers le distributeur de la figure 1, et
  • la figure 3 est une vue agrandie de la partie avant du distributeur de la figure 2.
In the figures:
  • FIG. 1 is a view from above of a fluid dispenser according to the invention,
  • FIG. 2 is a vertical cross-sectional view through the dispenser of FIG. 1, and
  • FIG. 3 is an enlarged view of the front portion of the dispenser of FIG. 2.

Le distributeur de produit fluide pulvérulent représenté sur les figures comprend quatre éléments constitutifs, à savoir une feuille profilée 2, une feuille de fond operculaire 3, une pièce de matière poreuse 4 et un embout 5. On peut éventuellement se passer de l'embout 5. La feuille profilée 2 forme un pourtour périphérique plan 21 et une partie centrale en relief sensiblement sous la forme d'un dôme. La feuille de fond operculaire 3 est reliée de manière étanche à la feuille profilée 2 au niveau du pourtour plan 21 de manière à isoler le volume formé au niveau de la partie centrale en relief. Le volume ainsi créé va servir en majeure partie de réservoir de produit fluide pulvérulent 23. Bien entendu, on peut réaliser un réservoir de produit fluide d'une manière totalement différente, sans utiliser de feuilles soudées l'une à l'autre. Par exemple, le réservoir peut être constitué par un récipient à parois souples. Ce récipient à parois souples peut se présenter sous la forme d'une petite fiole en matière écrasable ou encore sous la forme d'une poche souple réalisée à partir de feuilles librement déformables. La structure du réservoir n'est pas critique pour la présente invention. Mais dans l'exemple utilisé pour illustrer la présente invention et représenté sur les figures, le distributeur est réalise à partir de deux feuilles soudées ensemble pour former entre elles un réservoir de produit fluide pulvérulent.The powdery fluid dispenser shown in the figures comprises four constituent elements, namely a profiled sheet 2, an opercular bottom sheet 3, a piece of porous material 4 and a nozzle 5. It is possible to dispense with the nozzle 5 The profiled sheet 2 forms a peripheral peripheral plane 21 and a raised central portion substantially in the form of a dome. The opercular bottom sheet 3 is sealingly connected to the profiled sheet 2 at the plane periphery 21 so as to isolate the volume formed at the raised central portion. The volume thus created will serve mainly as a fluid reservoir powder 23. Of course, one can achieve a fluid reservoir in a completely different way, without using sheets welded to each other. For example, the reservoir may be constituted by a container with flexible walls. This soft-walled container may be in the form of a small vial of crushable material or in the form of a flexible bag made from freely deformable sheets. The tank structure is not critical for the present invention. But in the example used to illustrate the present invention and shown in the figures, the dispenser is made from two sheets welded together to form between them a fluid reservoir powder.

Selon une caractéristique de l'invention, l'orifice de distribution n'est pas formée par les feuilles 2 ou 3, mais par l'embout 5 qui est disposé entre les deux feuilles 2 et 3 comme on peut le voir plus clairement sur la figure 3. Les feuilles 2 et 3 peuvent par exemple être fixées par soudage sur l'embout 5. On voit sur la figure 3 que la feuille profilée 2 est fixée à l'embout 5 au niveau d'une partie 27. Avantageusement, l'embout 5 peut être pourvu de nervures de soudage 54 destinées à fondre au moins partiellement pour améliorer la cohésion entre la feuille profilée 2 et l'embout 5. L'embout 5 forme ainsi un orifice de pulvérisation 53 qui communique avec le réservoir désigné dans son ensemble par la référence numérique 23. Selon une forme de réalisation non limitative, une chambre de mélangeage 55 est disposée immédiatement en amont de l'orifice de pulvérisation 53.According to a characteristic of the invention, the dispensing orifice is not formed by the sheets 2 or 3, but by the tip 5 which is arranged between the two sheets 2 and 3 as can be seen more clearly on the 3. The sheets 2 and 3 can for example be fixed by welding on the endpiece 5. It can be seen in FIG. 3 that the profiled sheet 2 is fixed to the endpiece 5 at a portion 27. Advantageously, the tip 5 may be provided with welding ribs 54 for at least partially melting to improve the cohesion between the profiled sheet 2 and the nozzle 5. The nozzle 5 thus forms a spray orifice 53 which communicates with the tank designated in in its non-limiting embodiment, a mixing chamber 55 is disposed immediately upstream of the spray orifice 53.

Selon l'invention, le réservoir de produit fluide 23 contient une pièce de matière poreuse 4 apte à s'imprégner de produit fluide pulvérulent. Avantageusement, la quasi totalité ou la totalité du produit fluide est imprégné à l'intérieur de cette pièce de matière poreuse 4. Lorsqu'une chambre de mélangeage 55 est prévue, comme c'est le cas sur les figures 2 et 3, il se peut qu'une faible quantité de produit fluide pulvérulent soit présente à ce niveau. En réalité, la chambre de mélangeage 55 sépare la pièce de matière poreuse 4 de l'orifice de pulvérisation 53. Cette chambre de mélangeage 55 permet la formation de turbulences qui sont propices au transport du produit fluide pulvérulent à travers l'orifice de pulvérisation 53. La pièce de matière poreuse 4, qui est imprégnée de produit fluide pulvérulent, contient également du gaz, par exemple de l'air. Avantageusement, la proportion de gaz contenue à l'intérieur de la pièce de matière poreuse 4 est significativement plus importante que la quantité de produit fluide pulvérulent. La pièce de matière poreuse 4 est avantageusement du type à cellules ouvertes, c'est-à-dire constituée d'un enchevêtrement de canaux qui communiquent les uns avec les autres de sorte que la pièce de matière poreuse 4 est perméable de part en part. Lorsque la pièce de matière poreuse 4 n'est que faiblement chargée de produit fluide pulvérulent, les cellules ouvertes ne sont pas bouchées, ce qui permet au flux de gaz de passer à travers les cellules en entraînant ainsi le produit fluide pulvérulent en direction de l'orifice de pulvérisation 53.According to the invention, the fluid reservoir 23 contains a piece of porous material 4 able to impregnate pulverulent fluid product. Advantageously, substantially all or all of the fluid product is impregnated inside this piece of porous material 4. When a mixing chamber 55 is provided, as is the case in Figures 2 and 3, it is may a small amount of powdery fluid be present at this level. In fact, the mixing chamber 55 separates the piece of porous material 4 from the spray orifice 53. This mixing chamber 55 allows the formation of turbulences which are conducive to the transport of the pulverulent fluid product through the spray orifice 53 The piece of porous material 4, which is impregnated with pulverulent fluid, also contains gas, by example of the air. Advantageously, the proportion of gas contained inside the piece of porous material 4 is significantly greater than the quantity of pulverulent fluid product. The piece of porous material 4 is advantageously of the open cell type, that is to say formed of an entanglement of channels which communicate with each other so that the piece of porous material 4 is permeable from one side to the other . When the piece of porous material 4 is only weakly loaded with pulverulent fluid, the open cells are not clogged, which allows the flow of gas to pass through the cells, thus causing the powdery fluid product towards the spray orifice 53.

La partie en relief formée par la feuille profilée 2 forme avantageusement une paroi d'actionnement déplaçable 22. Dans le cas présent le déplacement de la paroi d'actionnement s'effectue par déformation en exerçant une pression d'enfoncement, par exemple à l'aide du pouce de la main. Ainsi, en enfonçant cette paroi d'actionnement 22 on diminue le volume interne du réservoir 23 ce qui a pour effet de mettre le gaz contenu dans le réservoir sous pression. En résultat, le gaz est refoulé en direction de l'orifice de pulvérisation 53 en transportant avec lui une partie du produit fluide pulvérulent. Il est avantageux que la paroi d'actionnement 22 présente une mémoire de forme lui permettant de revenir dans sa position de repos définissant le volume maximal du réservoir. Cette position est celle de la figure 2. Pour permettre le retour de la paroi d'actionnement vers sa position de repos, des moyens de ressort de rappel élastique sont nécessaires. Ces moyens de rappel élastique peuvent être directement formés par la paroi d'actionnement 22. Par exemple, il suffit de lui conférer une forme et une résilience telle qu'elle va revenir d'elle-même automatiquement vers sa position de repos dès que la pression d'enfoncement est relâchée. En variante, on peut également prévoir que les moyens de rappel élastique sont générés par la pièce de matière poreuse 4 située à l'intérieur du réservoir 23. Dans ce cas, il n'est même pas nécessaire d'utiliser une feuille profilée spéciale, par exemple du type thermoformé. On peut utiliser une simple feuille souple qui sera profilée en raison de la présence de la pièce de matière poreuse 4 à l'intérieur du réservoir 23. Dans ce cas, le retour de la paroi d'actionnement 22 vers sa position de repos est entièrement assuré par l'élasticité de la pièce de matière poreuse 4, qui est située juste en dessous de la paroi d'actionnement. Le distributeur peut alors se résumer à une simple pièce de matière poreuse élastiquement déformable incluse à l'intérieur d'une poche souple déformable dénuée de mémoire de forme intrinsèque. L'embout 5 peut même être omis. Dans ce cas, l'orifice de pulvérisation est directement formé au niveau d'une des deux feuilles ou entre les deux feuilles.The raised part formed by the profiled sheet 2 advantageously forms a displaceable actuating wall 22. In this case, the displacement of the actuating wall is effected by deformation by exerting a driving pressure, for example at using the thumb of the hand. Thus, by pressing this actuating wall 22 decreases the internal volume of the reservoir 23 which has the effect of putting the gas contained in the reservoir under pressure. As a result, the gas is discharged towards the spray orifice 53 by carrying with it a portion of the powdery fluid product. It is advantageous that the actuating wall 22 has a shape memory allowing it to return to its rest position defining the maximum volume of the reservoir. This position is that of Figure 2. To allow the return of the actuating wall to its rest position, resilient return spring means are required. These elastic return means may be directly formed by the actuating wall 22. For example, it suffices to give it a shape and a resilience such that it will automatically return to its rest position as soon as the depressing pressure is released. Alternatively, it is also possible that the elastic return means are generated by the piece of porous material 4 located inside the tank 23. In this case, it is not even necessary to use a special profiled sheet, for example of the thermoformed type. One can use a simple flexible sheet which will be profiled because of the presence of the piece of matter porous 4 inside the reservoir 23. In this case, the return of the actuating wall 22 to its rest position is entirely ensured by the elasticity of the piece of porous material 4, which is located just below the actuating wall. The dispenser can then be summed up in a simple piece of porous elastically deformable material included inside a deformable flexible pouch devoid of intrinsically shaped memory. The tip 5 can even be omitted. In this case, the spray orifice is directly formed at one of the two sheets or between the two sheets.

La pièce de matière poreuse 4 peut occuper la totalité du volume du réservoir 23 et s'étendre jusqu'au contact direct de l'orifice de pulvérisation 53. En variante, la pièce de matière poreuse 4 peut occuper une proportion plus restreinte du réservoir, par exemple la moitié du réservoir, 60% du réservoir ou même 75% du réservoir. En tout cas, la pièce de matière poreuse occupe de préférence la majeure partie du volume du réservoir.The piece of porous material 4 can occupy the entire volume of the tank 23 and extend to the direct contact of the spray orifice 53. As a variant, the piece of porous material 4 can occupy a smaller proportion of the tank, for example half of the tank, 60% of the tank or even 75% of the tank. In any case, the piece of porous material preferably occupies most of the volume of the tank.

Dans l'exemple utilisé pour illustrer l'invention, l'orifice de pulvérisation 53 est obturé avant utilisation par un élément d'obturation amovible 20 qui est constitué par la feuille profilée 2 et la feuille operculaire 3 soudées ensemble. L'organe d'obturation amovible 20 peut être séparé du restant du distributeur le long d'une ligne de rupture 24 qui passe juste devant l'embout 5 au niveau duquel l'organe 20 forme une paroi d'obturation 25 en regard de l'orifice de pulvérisation 53. Ainsi, avant utilisation, le réservoir 23 est parfaitement isolé de l'extérieur. On peut même prévoir que la pièce de matière poreuse 4 soit comprimée à un état proche du maximal tant que l'organe d'obturation amovible est en place pour obturer l'orifice de pulvérisation 53. Dans ce cas, ce n'est qu'au moment du retrait de l'organe d'obturation amovible 20 que la pièce de matière poreuse 4 peut se détendre par entrée d'air dans le réservoir à travers l'orifice de pulvérisation 53. Le distributeur peut ainsi présenter une configuration particulièrement plate ou écrasée avant retrait de l'organe d'obturation amovible 20. L'utilisation d'une telle pièce de matière poreuse élastiquement déformable peut également être utilisée dans un distributeur de produit fluide liquide pour conférer à la paroi d'actionnement déplaçable une fonction de rappel élastique vers sa position de repos.In the example used to illustrate the invention, the spray orifice 53 is closed before use by a removable closure member 20 which is constituted by the profiled sheet 2 and the opercular sheet 3 welded together. The removable closure member 20 may be separated from the remainder of the dispenser along a line of rupture 24 which passes just in front of the nozzle 5 at which the member 20 forms a closure wall 25 opposite the Thus, before use, the reservoir 23 is perfectly isolated from the outside. It can even be provided that the piece of porous material 4 is compressed to a state close to the maximum as the removable closure member is in place to close the spray orifice 53. In this case, it is only that at the time of removal of the removable closure member 20 that the piece of porous material 4 can relax by air entering the tank through the spray orifice 53. The dispenser can thus have a particularly flat configuration or crushed before removal of the removable closure member 20. The use of such a piece of porous material elastically deformable can also be used in a liquid fluid dispenser for conferring on the movable actuating wall an elastic return function towards its rest position.
