The more the product is viscous, the greater the overpressure necessary to spray it. Through elsewhere, the overpressure inside the container is maximum at the start of use of the device, that is to say when the tank contains little air. After several uses, the container contains more and more air, which compresses when the tank volume decreases.

Description

La présente invention concerne un dispositif de conditionnement et de distribution sous forme pulvérisée d'un produit fluide. En particulier, l'invention concerne un pulvérisateur miniature adapté au conditionnement de produits cosmétiques, notamment de parfums.The present invention relates to a device for packaging and distribution in sprayed form of a fluid product. In particular, the invention concerns a miniature sprayer suitable for packaging products cosmetics, especially perfumes.

Des distributeurs de ce type sont décrits notamment dans les demandes de brevet FR-A-2 778 639, EP-A-0 761 314, FR-A-2 443 980, ou dans les brevets US-A-3 897 005, ou US-A-3 412 907. Tous ces dispositifs souffrent principalement d'au moins un handicap, lié soit à leur coût de fabrication, soit à leur facilité d'utilisation, soit à la qualité du spray qu'ils sont capables de générer.Distributors of this type are described in particular in the requests for patent FR-A-2 778 639, EP-A-0 761 314, FR-A-2 443 980, or in patents US-A-3,897,005, or US-A-3,412,907. All of these devices suffer mainly at least one handicap, linked either to their manufacturing cost or to their ease of use, or the quality of the spray they are capable of generate.

En effet, les échantillons n'étant généralement pas destinés à la vente, leur coût de fabrication doit être aussi faible que possible. Il est donc important d'avoir des dispositifs dont les pièces soient aisément réalisables en grande série et dont le montage puisse être effectué de manière simple. En outre, ils doivent être en mesure de générer un spray dont la qualité soit aussi bonne que possible, et dont les caractéristiques soient aussi constantes que possible. Il est également souhaitable qu'ils génèrent un spray relativement doux, pendant une certaine durée, de manière à ce que ce spray se rapproche d'une pulvérisation de type aérosol.Indeed, since the samples are not generally intended for sale, their cost manufacturing should be as low as possible. It is therefore important to have devices whose parts can be easily produced in large series and whose assembly can be carried out in a simple manner. In addition, they must be able to generate a spray whose quality is as good as possible, and whose characteristics are as constant as possible. It is also desirable that they generate a relatively mild spray, during a certain duration, so that this spray approaches a spray aerosol type.

Une solution pour réaliser de tels conditionnements à un coût aussi faible que possible consisterait à réaliser le réservoir sous forme d'une dosette du type de ce qui est utilisé couramment pour le conditionnement de certains sérums physiologiques, collyres ou produits démaquillants. Une telle dosette est réalisée en une seule pièce avec un orifice de pulvérisation dont l'ouverture est provoquée par arrachage d'un embout, notamment par une torsion de l'embout autour de l'axe de l'orifice. Le remplissage d'un tel dispositif peut se faire via le fond ouvert du réservoir. Ce dernier est ensuite refermé notamment par soudage, à la manière d'un tube.A solution to carry out such packaging at a cost as low as possible would consist in making the reservoir in the form of a pod of the type of which is commonly used for the packaging of certain serums physiological, eye drops or make-up removing products. Such a pod is made in one piece with a spray opening whose opening is caused by tearing off a tip, in particular by twisting the tip around the axis of the hole. The filling of such a device can be done via the open tank bottom. The latter is then closed in particular by welding, like a tube.

Une telle solution souffre toutefois de deux inconvénients majeurs. Le premier tient au fait qu'à l'ouverture, l'orifice qui résulte de l'arrachage de l'embout par torsion est de forme et de dimensions imprécises. Il en résulte que le spray pouvant être obtenu au travers d'un tel orifice, lorsque l'on presse les parois compressibles du réservoir, présente des caractéristiques variant fortement d'un dispositif à l'autre. Souvent même, la section de l'orifice est telle, qu'il n'est pas possible de générer un spray. Le produit ne peut que s'écouler sous forme de gouttes plus ou moins grosses ou d'un filet continu.However, such a solution suffers from two major drawbacks. The first is due to the fact that at the opening, the orifice which results from the tearing of the end piece by torsion is of imprecise shape and dimensions. As a result, the spray obtainable through such an orifice when the walls are pressed compressible of the tank, has characteristics varying greatly from one device to another. Often even, the section of the orifice is such that it is not not possible to generate a spray. The product can only flow in the form more or less large drops or a continuous stream.

En outre, l'opération de soudage, après remplissage du réservoir, notamment lorsqu'il s'agit d'un produit fortement volatile tel qu'un parfum, n'est pas sans poser de problème. Sous l'effet de la chaleur, le produit risque de s'évaporer, de se détériorer, voire de s'enflammer.In addition, the welding operation, after filling the tank, in particular when it is a highly volatile product such as a perfume, is not without to pose a problem. Under the effect of heat, the product may evaporate, deteriorate or even ignite.

Par ailleurs, la qualité du spray dépend de la vitesse avec laquelle on presse les parois compressibles du réservoir. En effet, si on presse lentement les parois, la pulvérisation est de mauvaise qualité. C'est pourquoi le document FR 2 778 639 décrit un dispositif de pulvérisation dans lequel la paroi du réservoir présente un seuil de résistance à la déformation qui permet d'obtenir un spray de bonne qualité. Néanmoins, dans ce type de dispositif, on ne prévoit pas de réaliser un spray dont la durée de pulvérisation peut être modulée.Furthermore, the quality of the spray depends on the speed with which it is pressed. the compressible walls of the tank. Indeed, if we slowly press the walls, the spraying is of poor quality. This is why the document FR 2 778 639 describes a spraying device in which the wall of the tank has a threshold of resistance to deformation which makes it possible to obtain a good quality spray. However, in this type of device, no provision is made not to carry out a spray whose spraying duration can be modulated.

Aussi, est-ce un des objets de l'invention que de réaliser un tel dispositif de pulvérisation, résolvant en tout ou partie les problèmes discutés ci-avant en référence aux dispositifs conventionnels.Also, is it an object of the invention to provide such a device for spraying, solving all or part of the problems discussed above in reference to conventional devices.

C'est en particulier un objet de l'invention que de réaliser un tel dispositif qui soit facile à produire en grande série, avec un coût de revient aussi faible que possible. It is in particular an object of the invention to produce such a device which is easy to mass produce, with a cost price as low as possible.

C'est un autre objet de l'invention que de fournir un tel dispositif qui permette de générer un spray de qualité à la fois satisfaisante, et reproductible d'un dispositif à l'autre.It is another object of the invention to provide such a device which allows generate a spray of quality that is both satisfactory and reproducible device to another.

C'est encore un autre objet que de fournir un dispositif capable de générer une pulvérisation pendant une certaine durée, que l'on peut faire varier, et qui permet d'obtenir un spray relativement doux.It is yet another object to provide a device capable of generating a spraying for a certain period, which can be varied, and which provides a relatively mild spray.

Selon l'invention, ces objets sont atteints en réalisant un dispositif de distribution d'un produit fluide comprenant un réservoir contenant ledit produit et équipé d'un orifice de pulvérisation, ledit réservoir ayant au moins une paroi d'actionnement déformable en réponse à une pression exercée sur ladite paroi de manière à provoquer la pulvérisation du produit au travers dudit orifice, ladite paroi d'actionnement présentant un seuil prédéterminé de résistance à la déformation, de sorte qu'avant que la pression exercée atteigne une pression Ps nécessaire et suffisante pour vaincre ledit seuil prédéterminé de résistance à la déformation, le volume de produit pulvérisé est sensiblement nul, le dispositif étant configuré de sorte que, au moins lors de sa première utilisation, l'exercice continu de la pression de seuil Ps provoque une pulvérisation dont la durée peut être modulée.According to the invention, these objects are achieved by producing a device for dispensing a fluid product comprising a reservoir containing said product and equipped with a spray orifice, said reservoir having at least one deformable actuating wall in response to a pressure exerted on said wall so as to cause the product to be sprayed through said orifice, said actuating wall having a predetermined threshold of resistance to deformation, so that before the pressure exerted reaches a pressure P s necessary and sufficient to overcome said predetermined threshold of resistance to deformation, the volume of sprayed product is substantially zero, the device being configured so that, at least during its first use, the continuous exercise of the threshold pressure P s causes a spraying the duration of which can be varied.

Au sens de la présente invention, par "une paroi présentant un seuil de résistance à la déformation" on entend une paroi configurée de manière telle que sa déformation ne dépend pas linéairement de la pression exercée dessus pour la déformer, mais nécessite le dépassement d'un seuil. Ainsi, la pression exercée par un utilisateur sur la paroi d'actionnement entraíne, avant d'atteindre la pression de seuil Ps, à savoir, la pression nécessaire et suffisante pour vaincre ledit seuil prédéterminé de résistance à la déformation de ladite paroi d'actionnement, une déformation de la paroi qui ne permet pas de pulvériser du produit mais qui permet d'accumuler de l'énergie de sorte que, lorsque la pression exercée par l'utilisateur sur la paroi atteint la pression de seuil Ps, la paroi se déforme brutalement. Le volume à l'intérieur du réservoir se réduit alors de sorte qu'une surpression est créée brutalement à l'intérieur du réservoir. Cette surpression permet de faire sortir le produit au travers de l'orifice sous forme d'un spray de bonne qualité.Within the meaning of the present invention, by "a wall having a threshold of resistance to deformation" means a wall configured in such a way that its deformation does not depend linearly on the pressure exerted on it to deform it, but requires the passing of a threshold. Thus, the pressure exerted by a user on the actuating wall causes, before reaching the threshold pressure P s , namely, the pressure necessary and sufficient to overcome said predetermined threshold of resistance to deformation of said wall. actuation, a deformation of the wall which does not make it possible to spray product but which makes it possible to accumulate energy so that, when the pressure exerted by the user on the wall reaches the threshold pressure P s , the wall abruptly deforms. The volume inside the tank is reduced so that an overpressure is created suddenly inside the tank. This overpressure allows the product to exit through the orifice in the form of a good quality spray.

En fonction de la plage de temps sur laquelle on souhaite moduler la durée de pulvérisation, on détermine les paramètres du dispositif, notamment la section de l'orifice de sortie et son débit maximal, en fonction en particulier de la viscosité du produit et de la surpression apte à être générée à l'intérieur du réservoir en réponse à la pression exercée sur la paroi d'actionnement. Dans la détermination de ces paramètres, on jouera notamment sur la nature des matériaux, sur l'épaisseur de la paroi d'actionnement, sur son profil, sur le volume du réservoir, etc.Depending on the time range over which we want to modulate the duration of spraying, the parameters of the device are determined, in particular the cross-section of the outlet and its maximum flow rate, depending in particular on the viscosity of the product and the overpressure capable of being generated inside the reservoir in response to the pressure exerted on the actuating wall. In the determination of these parameters, we will play in particular on the nature of materials, on the thickness of the actuating wall, on its profile, on the tank volume, etc.

Avantageusement, la durée de pulvérisation est modulée en fonction de la durée d'exercice de la pression sur la paroi d'actionnement.Advantageously, the duration of spraying is modulated as a function of the duration of pressure on the actuating wall.

Bien évidemment, la plage de modulation du temps n'est pas infinie. En effet, au bout d'un certain temps d'exercice continu de ladite pression Ps, si on n'apporte pas d'énergie supplémentaire, la surpression à l'intérieur du réservoir va passer en dessous de la valeur requise pour provoquer la distribution sous forme pulvérisée. Cette dernière est alors interrompue. En relâchant la pression exercée sur la paroi d'actionnement, puis en appuyant à nouveau sur cette dernière, on est à nouveau en position de moduler la durée de pulvérisation, et ce jusqu'à ce que le volume de produit dans le réservoir devienne insuffisant pour obtenir la moindre pulvérisation en réponse à ladite pression Ps. Dans ce cas, et pour assurer un taux de vidange maximal du réservoir, il pourra être nécessaire d'exercer une pression supérieure à la pression Ps.Obviously, the time modulation range is not infinite. In fact, after a certain period of continuous exercise of said pressure P s , if no additional energy is supplied, the overpressure inside the tank will drop below the value required to cause the distribution in spray form. The latter is then interrupted. By releasing the pressure exerted on the actuating wall, then pressing it again, we are again in a position to modulate the duration of spraying, until the volume of product in the tank becomes insufficient to obtain the least spray in response to said pressure P s . In this case, and to ensure a maximum emptying rate of the tank, it may be necessary to exert a pressure greater than the pressure P s .

Avantageusement, le dispositif est configuré sous forme d'une dose échantillon contenant un produit cosmétique, notamment un parfum, ladite durée de pulvérisation pouvant être modulée sur une plage allant de 1s à 45s, et de préférence de 2s à 10s.Advantageously, the device is configured in the form of a sample dose. containing a cosmetic product, in particular a perfume, said duration of spraying can be modulated over a range from 1s to 45s, and from preferably from 2s to 10s.

Avantageusement encore, la paroi d'actionnement est à mémoire de forme, c'est-à-dire qu'elle est configurée de manière à reprendre sa forme initiale par rappel élastique lorsque cesse ladite pression. Le dispositif peut alors être utilisé plusieurs fois consécutivement.Advantageously also, the actuating wall is with shape memory, that is, it is configured to return to its original form by elastic return when said pressure ceases. The device can then be used several times consecutively.

Selon un mode de réalisation préféré, la paroi d'actionnement présente un profil sensiblement convexe dans sa position non déformée, notamment en forme de dôme, et un profil sensiblement concave dans sa position déformée lorsque le seuil prédéterminé de résistance à la déformation de ladite paroi d'actionnement a été dépassé. Une telle configuration permet de facilement obtenir une paroi avec un seuil de résistance à la déformation qui correspond au passage entre le profil concave et le profil convexe. En outre, cette configuration facilite le retour de la paroi en position convexe lorsque cesse la pression.According to a preferred embodiment, the actuating wall has a profile substantially convex in its undistorted position, in particular in the form of dome, and a substantially concave profile in its deformed position when the predetermined threshold for resistance to deformation of said wall actuation has been exceeded. Such a configuration makes it easy to obtain a wall with a threshold of resistance to deformation which corresponds when passing between the concave profile and the convex profile. In addition, this configuration facilitates the return of the wall to the convex position when the pressure.

La paroi d'actionnement du réservoir est formée d'un matériau thermoplastique, notamment un polyéthylène, un polypropylène, un polyéthylène téréphtalate, un polyéthylène naphtalate, un polyacrylonitrile, un polyoxyméthylène, un polychlorure de vinyle, ou un mélange de ces matériaux.The actuating wall of the reservoir is formed of a thermoplastic material, in particular a polyethylene, a polypropylene, a polyethylene terephthalate, a polyethylene naphthalate, a polyacrylonitrile, a polyoxymethylene, a polyvinyl chloride, or a mixture of these materials.

Avantageusement, l'orifice de pulvérisation est ménagé dans un diffuseur réalisé sous forme d'une buse à un ou plusieurs canaux tourbillonnaires. Les canaux tourbillonnaires permettent ainsi d'accélérer le fluide en amont de l'orifice de manière à produire des particules de liquide très fines. Il est évident que l'orifice peut alternativement être ménagé dans une simple buse.Advantageously, the spray orifice is formed in a diffuser produced in the form of a nozzle with one or more vortex channels. The vortex channels thus accelerate the fluid upstream of the orifice so as to produce very fine liquid particles. It is obvious that the orifice can alternatively be formed in a simple nozzle.

Le diffuseur est monté sur le réservoir, notamment par encliquetage ou vissage. Ainsi, lorsque le réservoir est vide, on peut retirer le diffuseur de manière à remplir le réservoir afin de le réutiliser. Alternativement, on peut prévoir un élément intermédiaire entre le réservoir et le diffuseur. L'élément intermédiaire est par exemple un embout qui est monté sur le réservoir, notamment par encliquetage ou vissage. Le diffuseur est alors monté sur ledit embout, par collage ou soudage, notamment à chaud. The diffuser is mounted on the tank, in particular by snap-fastening or screwing. So when the tank is empty, you can remove the diffuser so that fill the tank for reuse. Alternatively, a intermediate element between the tank and the diffuser. The intermediate element is for example a nozzle which is mounted on the reservoir, in particular by latching or screwing. The diffuser is then mounted on said end piece, by bonding or welding, especially hot.

Le dispositif est particulièrement adapté pour le conditionnement et la pulvérisation d'une dose échantillon d'un produit cosmétique, notamment d'un parfum.The device is particularly suitable for packaging and spraying of a sample dose of a cosmetic product, in particular of a perfume.

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • Figure 1 illustrates a perspective view of a preferred embodiment of the spray device according to the invention;

Le dispositif représenté en vue d'ensemble à la figure 1 et en vue en coupe aux figures 2 et 3 comprend un réservoir 10 à paroi déformable, contenant le produit à distribuer, sur lequel est monté un diffuseur 20 dans lequel est ménagé un orifice de pulvérisation 21 en communication avec l'intérieur du réservoir. En exerçant une pression sur la paroi du réservoir, on crée une surpression à l'intérieur du réservoir qui entraíne la pulvérisation du produit au travers de l'orifice.The device shown in overview in Figure 1 and in section through Figures 2 and 3 includes a reservoir 10 with a deformable wall, containing the product to be dispensed, on which is mounted a diffuser 20 in which a spray orifice 21 in communication with the interior of the reservoir. In exerting pressure on the wall of the tank, an overpressure is created at inside the tank which causes the product to be sprayed through the orifice.

Selon le mode de réalisation représenté, le réservoir 10 est configuré sous forme d'une goutte d'eau, mais il est évident qu'il peut présenter toute autre forme autorisant la déformation d'au moins une de ses parois. Il est obtenu par moulage, notamment par injection soufflage, par exemple d'une seule pièce, d'un matériau thermoplastique, notamment d'un polyéthylène, d'un polypropylène, d'un polyéthylène téréphtalate, d'un polyéthylène naphtalate, d'un polyacrylonitrile, d'un polyoxyméthylène, d'un polychlorure de vinyle, ou encore d'un mélange de ces matériaux. Il présente une paroi d'actionnement 11 de forme bombée qui est déformable lorsqu'on exerce une pression dessus. According to the embodiment shown, the reservoir 10 is configured under form of a drop of water, but it is obvious that it can present any other shape allowing the deformation of at least one of its walls. It is obtained by molding, in particular by injection blow molding, for example in one piece, a thermoplastic material, in particular a polyethylene, a polypropylene, a polyethylene terephthalate, a polyethylene naphthalate, a polyacrylonitrile, a polyoxymethylene, a polyvinyl chloride, or still a mixture of these materials. It has an actuating wall 11 domed shape which is deformable when pressure is applied to it.

Cette paroi est à mémoire de forme de sorte qu'elle reprend sa position initiale lorsqu'on cesse d'exercer une pression dessus. A l'opposé de cette paroi d'actionnement 11, le réservoir 10 a une paroi plane 12. Cette configuration du réservoir permet de facilement identifier la zone sur laquelle l'utilisateur doit exercer une pression de sorte que le fonctionnement du dispositif est rendu évident. En outre, cette configuration permet de facilement saisir le dispositif entre deux doigts, par exemple en plaçant le pouce sur la paroi plane 12 et l'index sur la paroi d'actionnement 11 ou inversement. L'utilisateur exerce ainsi une pression sur la paroi d'actionnement à l'aide de son index ou de son pouce de sorte qu'il peut aisément pulvériser le produit.This wall has shape memory so that it returns to its initial position when you stop putting pressure on it. Opposite this wall actuation 11, the reservoir 10 has a flat wall 12. This configuration of the tank makes it easy to identify the area where the user should apply pressure so that the operation of the device is made obvious. In addition, this configuration allows the device to be easily grasped between two fingers, for example by placing the thumb on the flat wall 12 and the index on the actuating wall 11 or vice versa. The user thus exercises pressure on the actuating wall using his index finger or thumb so that it can easily spray the product.

Le réservoir 10 se termine par un col 13 ouvert, fileté sur sa surface extérieure. Un diffuseur 20 est vissé sur le col du réservoir en étant disposé dans le prolongement de la paroi du réservoir de manière à former l'extrémité de la goutte d'eau. Le diffuseur 20 est muni d'une jupe de fixation 22, filetée sur sa surface intérieure pour venir coopérer avec le col 13 du réservoir 10. Une jupe d'étanchéité 23, cylindrique, est prévue pour venir se loger à l'intérieur du col 13 du réservoir et ainsi assurer l'étanchéité entre l'ouverture du col 13 et le diffuseur. Le diffuseur 20 est obtenu par moulage, par exemple d'une seule pièce, d'un matériau thermoplastique, notamment de polyéthylène ou de polypropylène.The reservoir 10 ends with an open neck 13, threaded on its outer surface. A diffuser 20 is screwed onto the neck of the reservoir while being disposed in the extension of the tank wall so as to form the end of the water drop. The diffuser 20 is provided with a fixing skirt 22, threaded on its inner surface to cooperate with the neck 13 of the reservoir 10. A skirt sealing 23, cylindrical, is provided to be housed inside the neck 13 of the reservoir and thus ensure sealing between the opening of the neck 13 and the Streamer. The diffuser 20 is obtained by molding, for example from a single piece, of a thermoplastic material, in particular of polyethylene or polypropylene.

Une buse 30 à canaux tourbillonnaires est montée sur le diffuseur 20. L'orifice de pulvérisation 21 est ménagé dans la buse et est en communication avec l'intérieur du réservoir via l'intérieur du col 13. La buse 30 est montée sur le diffuseur par n'importe quel moyen adéquat, par exemple par collage, soudage, serrage, ou encliquetage.A nozzle 30 with swirl channels is mounted on the diffuser 20. The orifice spray 21 is formed in the nozzle and is in communication with inside the tank via the inside of the neck 13. The nozzle 30 is mounted on the diffuser by any suitable means, for example by gluing, welding, tightening, or snap-fastening.

La figure 4 représente un dispositif de pulvérisation dans lequel on a remplacé le diffuseur 20 muni de la buse 30 tel qu'il vient d'être décrit par un simple embout 40 muni d'un orifice de pulvérisation 21. L'embout 40 comporte une jupe de fixation 42 filetée sur sa surface extérieure de manière à être vissée sur le col 13 du récipient 10. L'embout 40 comporte également une jupe d'étanchéité 43 destinée à se loger à l'intérieur du col 13 du réservoir. FIG. 4 represents a spraying device in which one has replaced the diffuser 20 provided with the nozzle 30 as just described by a simple nozzle 40 provided with a spray orifice 21. The nozzle 40 has a fixing skirt 42 threaded on its outer surface so as to be screwed onto the neck 13 of the container 10. The end piece 40 also includes a skirt seal 43 intended to be housed inside the neck 13 of the tank.

Dans les deux modes de réalisation qui viennent d'être décrits, le réservoir est configuré de manière à générer un spray de bonne qualité. A cet effet, la paroi d'actionnement 11 présente un seuil prédéterminé de résistance à la déformation en deçà duquel la paroi se déforme légèrement et au-delà duquel, la paroi se déforme brusquement pour présenter un profil concave comme cela est représenté à la figure 3. Ce seuil est déterminé en fonction de la géométrie de la paroi d'actionnement mais aussi de la nature du matériau utilisé pour former cette paroi et enfin de l'épaisseur de la paroi. Ainsi, le réservoir peut passer d'une première position convexe correspondant à sa position non déformée, à une seconde position concave correspondant à sa position déformée. Cette seconde position est préétablie, là encore en fonction de la géométrie de la paroi. La géométrie de la paroi est telle que la pression à exercer nécessaire pour maintenir cette position déformée est inférieure à la pression de seuil Ps nécessaire pour passer le seuil de résistance à la déformation, si bien que l'utilisateur n'a pas tendance à exercer une pression plus importante sur la paroi après avoir atteint sa position concave. En conséquence, cette seconde position préétablie sera sensiblement la même à chaque utilisation. Pour un réservoir donné, on peut ainsi facilement déterminer le volume déformable, à savoir la variation de volume entre la position non déformée et la position déformée préétablie. En outre, le reste du réservoir n'est sensiblement pas déformé de sorte que, lorsque la paroi d'actionnement est déformée, le volume intérieur du réservoir diminue. Une surpression est alors créée à l'intérieur du réservoir qui entraíne la sortie du produit au travers de la buse. Or, cette surpression étant créée de manière très brusque lors du franchissement du seuil, le produit est brusquement poussé à s'écouler hors du réservoir au travers de l'orifice.In the two embodiments which have just been described, the reservoir is configured so as to generate a good quality spray. To this end, the actuating wall 11 has a predetermined threshold of resistance to deformation below which the wall deforms slightly and beyond which, the wall abruptly deforms to have a concave profile as shown in the figure. 3. This threshold is determined according to the geometry of the actuating wall but also to the nature of the material used to form this wall and finally to the thickness of the wall. Thus, the reservoir can pass from a first convex position corresponding to its non-deformed position, to a second concave position corresponding to its deformed position. This second position is pre-established, again as a function of the geometry of the wall. The geometry of the wall is such that the pressure to be exerted necessary to maintain this deformed position is less than the threshold pressure P s necessary to pass the threshold of resistance to deformation, so that the user does not tend to exert greater pressure on the wall after reaching its concave position. Consequently, this second preset position will be substantially the same at each use. For a given reservoir, it is thus easy to determine the deformable volume, namely the variation in volume between the non-deformed position and the pre-established deformed position. In addition, the remainder of the reservoir is not substantially deformed so that, when the actuating wall is deformed, the interior volume of the reservoir decreases. An overpressure is then created inside the tank which causes the product to exit through the nozzle. However, this overpressure being created very suddenly when crossing the threshold, the product is suddenly forced to flow out of the tank through the orifice.

Lorsque la paroi reprend sa forme initiale, de l'air entre alors dans le réservoir, notamment par l'orifice de pulvérisation. S'il reste du produit à l'intérieur du réservoir, on peut de nouveau créer une surpression en déformant la paroi d'actionnement et ainsi pulvériser une autre dose de produit. When the wall returns to its initial shape, air then enters the tank, especially through the spray orifice. If there is any product left inside the tank, we can again create an overpressure by deforming the wall actuation and thus spray another dose of product.

Afin d'obtenir un temps de pulvérisation maximum significatif pour un exercice de pression continu sur la paroi permettant à l'utilisateur de moduler le temps de pulvérisation, on choisit le débit moyen de la buse en fonction de la configuration du réservoir et de la viscosité du produit à pulvériser.In order to obtain a significant maximum spraying time for an exercise continuous pressure on the wall allowing the user to modulate the time spraying, we choose the average flow rate of the nozzle according to the configuration of the tank and the viscosity of the product to be sprayed.

Pour un réservoir donné, on peut déterminer le volume total de produit apte à être expulsé du réservoir en position déformée de la paroi d'actionnement. En effet, ce volume dépend de la viscosité du produit et de la surpression maximale à laquelle il est soumis en position déformée. Plus le produit est visqueux, plus la surpression nécessaire pour le pulvériser sera importante. Par ailleurs, la surpression à l'intérieur du récipient est maximale en début d'utilisation du dispositif, c'est-à-dire lorsque le réservoir contient peu d'air. Après plusieurs utilisations, le récipient contient de plus en plus d'air, qui se comprime lorsque le volume du réservoir diminue. La surpression générée par le passage de la paroi en position déformée est donc réduite. La surpression maximale est déterminée, en fonction du volume déformable du réservoir que l'on peut facilement déterminer comme on l'a vu précédemment. Si on souhaite que ce volume maximum puisse être pulvérisé pendant N secondes, on choisit alors une buse ayant un débit moyen inférieur ou égal au rapport entre le volume maximum de produit et N. En dessous de ces N secondes, si l'utilisateur relâche la pression qu'il exerce sur la paroi déformable pour maintenir la position concave, le réservoir retrouve son volume initial et de l'air rentre dans le réservoir par l'orifice de pulvérisation. Le produit n'est alors plus soumis à une surpression et la pulvérisation s'arrête.For a given tank, we can determine the total volume of product capable of be expelled from the reservoir in the deformed position of the actuating wall. In effect, this volume depends on the viscosity of the product and the overpressure maximum to which it is subjected in the deformed position. The more the product is viscous, the greater the overpressure necessary to spray it. Through elsewhere, the overpressure inside the container is maximum at the start of use of the device, that is to say when the tank contains little air. After several uses, the container contains more and more air, which compresses when the tank volume decreases. The overpressure generated by the passage of the wall in the deformed position is therefore reduced. Overpressure maximum is determined, depending on the deformable volume of the tank that we can easily determine as we saw previously. If we wish that this maximum volume can be sprayed for N seconds, we choose then a nozzle having an average flow rate less than or equal to the ratio between the maximum product volume and N. Below these N seconds, if the user releases the pressure he exerts on the deformable wall to maintain the concave position, the tank regains its initial volume and air enters the tank through the spray hole. The product is no longer overpressure and spraying stops.

Selon un exemple particulier donné à titre illustratif et non limitatif, on utilise un réservoir 10 réalisé en polyéthylène téréphtalate (PET). Le réservoir présente une paroi déformable qui, en position non déformée présente un profil convexe qui devient concave en position déformée. La paroi déformable à l'état non déformé est sensiblement une portion de sphère qui a un rayon de courbure de l'ordre de 50 mm. La paroi déformable présente une épaisseur d'environ 0,3 mm. A l'état non déformé, le réservoir a un volume de 7,5 ml. Le réservoir présente un volume déformable de 0,5 ml de sorte que, en position concave de la paroi d'actionnement, le volume du réservoir est de 7,0 ml. Si on souhaite pulvériser de l'eau pendant environ 5 secondes, on choisit une buse ayant un débit moyen de 0,1 ml. L'utilisateur pourra ainsi pulvériser du produit, en exerçant une pression continue sur la paroi déformable, pendant cinq secondes. Mais il pourra également pulvériser du produit pendant moins longtemps, par exemple pendant deux, trois ou quatre secondes.According to a particular example given by way of nonlimiting illustration, a tank 10 made of polyethylene terephthalate (PET). The tank has a deformable wall which, in the non-deformed position, has a convex profile which becomes concave in the deformed position. The deformable wall in the non-state deformed is substantially a portion of a sphere which has a radius of curvature of around 50 mm. The deformable wall has a thickness of approximately 0.3 mm. In the undeformed state, the reservoir has a volume of 7.5 ml. The reservoir has a deformable volume of 0.5 ml so that, in the concave position of the actuating wall, the volume of the reservoir is 7.0 ml. If we wish spray water for about 5 seconds, choose a nozzle with a average flow rate of 0.1 ml. The user will thus be able to spray product, exerting continuous pressure on the deformable wall for five seconds. But it can also spray product for less a long time, for example for two, three or four seconds.
