Abstract

The device has a mouthpiece (20) mounted on a reservoir (10) containing a product (P) and air, and comprising a spraying orifice (21) communicating with the reservoir via a dip tube (30). An air passage (31), permitting the air to be introduced in the tube when the product rises again in the tube, is formed in lateral wall of the tube. The position of the air passage is chosen such that, before the initial usage of the device and in partially deformed position of a bulged zone (11) of the reservoir, the passage is at the exterior of the product irrespective of the position of the reservoir. The reservoir presents a plane wall (12) opposite to the bulged zone (11).

Description

La présente invention concerne un dispositif de pulvérisation 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 spraying a fluid product. In particular, the invention relates to a miniature spray suitable for packaging cosmetic products, especially perfumes.

Les dispositifs de type échantillon 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.Because sample devices are generally not for sale, their cost of manufacture should be as low as possible. It is therefore important to have devices whose parts are easily achievable in large series and whose assembly can be performed 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.

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.One solution for producing such packages at a cost as low as possible would be to make the tank in the form of a pod of the type that is commonly used for the packaging of certain physiological serums, eye drops or makeup removers. Such a pod is made in one piece with a spray orifice whose opening is caused by tearing a tip, in particular by a twist of the tip around the axis of the orifice. The filling of such a device can be done via the open bottom of the tank. The latter is then closed, in particular by welding, in the manner of 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.Such a solution, however, suffers from two major disadvantages. The first is that at the opening, the orifice resulting from tearing the tip by torsion is imprecise shape and dimensions. As a result, the spray that can be obtained through such an orifice, when the compressible walls of the reservoir are pressed, has characteristics that vary greatly from one device to another. Often even, the section of the orifice is such that it is not possible to generate a spray. The product can only flow in the form of drops larger or smaller or a continuous net.

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, especially 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.

Une autre solution est décrite, notamment dans les brevets EP 1 279 607 , US 2,571,504 , US 2,642,313 , US 2,728,981 , GB 680 815 et GB 263 699 , qui consiste à utiliser un dispositif du type nébuliseur. Le dispositif décrit dans ces documents comprend un récipient à paroi déformable qui contient un produit liquide à pulvériser. Le récipient est surmonté d'une tête de pulvérisation munie d'un orifice de pulvérisation qui communique avec l'intérieur du récipient par l'intermédiaire d'un tube plongeur. Une arrivée d'air est prévue dans la partie supérieure du tube ou au dessus du tube. Lorsque l'on comprime le récipient, on réduit le volume intérieur du récipient de sorte que l'air est comprimé et pousse le produit à sortir du récipient. Le produit monte alors dans le tube plongeur. L'air comprimé tend également à s'échapper du récipient et entre dans le tube plongeur par l'arrivée d'air. Un mélange d'air et de produit est alors obtenu dans le tube avant la pulvérisation.Another solution is described, in particular in patents EP 1 279 607 , US 2,571,504 , US 2,642,313 , US 2,728,981 , GB 680 815 and GB 263,699 which consists in using a device of the nebulizer type. The device described in these documents comprises a deformable wall container which contains a liquid product to be sprayed. The container is surmounted by a spray head provided with a spray orifice which communicates with the interior of the container via a dip tube. An air inlet is provided in the upper part of the tube or above the tube. When the container is compressed, the interior volume of the container is reduced so that the air is compressed and pushes the product out of the container. The product then rises in the dip tube. The compressed air also tends to escape from the container and enters the dip tube through the air inlet. A mixture of air and product is then obtained in the tube before spraying.

Toutefois, dans certaines positions, l'arrivée d'air est immergée de produit en même temps que l'extrémité inférieure du tube plongeur. Si l'utilisateur presse la paroi déformable du réservoir dans une telle position, le produit est distribué sous forme d'un jet tel qu'un filet et non d'un spray de bonne qualité.However, in certain positions, the air inlet is immersed in product at the same time as the lower end of the dip tube. If the user presses the deformable wall of the tank in such a position, the product is distributed in the form of a jet such as a net and not a good quality spray.

Aussi, est-ce un des objets de l'invention que de réaliser un 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 a spray device, solving all or part of the problems discussed above with 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 particularly an object of the invention to provide such a device which is easy to produce in large series, with a cost 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 bonne qualité.It is another object of the invention to provide such a device which makes it possible to generate a spray of good quality.

Selon l'invention, ces objets sont atteints en réalisant un dispositif de pulvérisation d'un produit fluide comprenant :

  • un réservoir contenant le produit et de l'air, le réservoir comportant une paroi ayant au moins une zone déformable,
  • un tube plongeur qui communique de façon sélective ou permanente avec un orifice de pulvérisation apte à pulvériser le produit en réponse à une pression exercée sur la zone déformable, le tube plongeur comportant :
    • une première extrémité ;
    • une seconde extrémité, à l'opposé de la première, par laquelle le produit peut entrer ;
    • au moins un passage d'air pour permettre à au moins une partie de l'air contenu dans le réservoir de se mélanger avec le produit acheminé par le tube plongeur, le passage d'air étant situé entre les deux extrémités du tube plongeur,
le dispositif pouvant se caractériser en ce que, avant une première utilisation du dispositif et en position au moins partiellement déformée de la zone déformable, ledit au moins passage d'air est à l'extérieur du produit, quelle que soit la position du réservoir.According to the invention, these objects are achieved by producing a device for spraying a fluid product comprising:
  • a reservoir containing the product and air, the reservoir comprising a wall having at least one deformable zone,
  • a dip tube which selectively or permanently communicates with a spray orifice capable of spraying the product in response to a pressure exerted on the deformable zone, the dip tube comprising:
    • a first end;
    • a second end, opposite the first, through which the product can enter;
    • at least one air passage to allow at least a portion of the air contained in the reservoir to mix with the product conveyed by the dip tube, the air passage being located between the two ends of the dip tube,
the device being characterized in that, before a first use of the device and in at least partially deformed position of the deformable zone, said at least air passage is outside the product, regardless of the position of the reservoir.

Par « quelle que soit la position du réservoir », on entend quelle que soit la position sensiblement immobile du réservoir. Bien entendu, on n'exclut pas que lorsque l'on secoue le réservoir, du produit peut momentanément arriver au niveau du passage d'air.By "whatever the position of the tank", one hears whatever the substantially immobile position of the tank. Of course, it is not excluded that when shaking the tank, product may momentarily arrive at the level of the air passage.

Le passage d'air n'étant jamais immergé de produit, il ne peut servir à faire entrer du produit dans le tube plongeur. Ainsi, l'utilisateur ne pourra jamais faire sortir le produit sous forme d'un jet de mauvaise qualité, c'est-à-dire sans que le produit ne soit mélangé avec de l'air. Soit, le produit sera pulvérisé sous forme d'un spray grâce au mélange air-produit, soit de l'air seul sortira selon que la seconde extrémité du tube est immergée de produit ou non.Since the air passage is never immersed in product, it can not be used to introduce product into the dip tube. Thus, the user can never get the product out as a jet of poor quality, that is to say without the product is mixed with air. Either the product will be sprayed as a spray through the air-product mixture, or air alone will come out depending on whether the second end of the tube is immersed product or not.

Le passage d'air peut être à l'extérieur du produit lorsque la zone déformable est déformée à son maximum, dans des conditions normales d'utilisation.The air passage may be outside the product when the deformable zone is deformed to its maximum, under normal conditions of use.

La seconde extrémité du tube plongeur peut être située au voisinage du fond du réservoir de manière à ce que la plus grande partie du produit contenu dans le réservoir puisse être distribuée.The second end of the dip tube may be located near the bottom of the tank so that most of the product contained in the tank can be dispensed.

Le tube plongeur peut comporter plus d'un passage d'air, lorsque l'on souhaite par exemple obtenir un spray plus aéré. Le tube plongeur peut par exemple comporter deux passages d'air situés en regard l'un de l'autre. Le tube plongeur peut aussi comporter au moins deux passages d'air situés à deux hauteurs différentes.The plunger tube may comprise more than one air passage, when it is desired, for example, to obtain a more ventilated spray. The plunger tube may for example comprise two air passages located opposite one another. The dip tube may also include at least two air passages located at two different heights.

La section transversale du ou des passages d'air peut être circulaire, mais elle peut aussi être ovale, triangulaire, polygonale ou de toute autre forme. Lorsque le tube plongeur comporte plusieurs passages d'air, ils peuvent avoir une section identique ou différente.The cross section of the air passage or passages may be circular, but it may also be oval, triangular, polygonal or any other shape. When the plunger tube has several air passages, they may have the same or different section.

Le passage d'air peut déboucher en regard d'une portion de la paroi du réservoir située à l'opposé de la zone déformable. Ainsi, lorsque l'on presse la paroi du réservoir, le volume du réservoir est réduit à l'opposé du passage d'air ce qui évite que le produit soit amené au niveau du passage d'air.The air passage may open opposite a portion of the tank wall located opposite the deformable zone. Thus, when pressing the tank wall, the volume of the tank is reduced to the opposite of the air passage which prevents the product is brought to the level of the air passage.

L'orifice de pulvérisation peut déboucher selon un axe oblique par rapport à l'axe du tube plongeur. L'orifice de pulvérisation peut aussi déboucher selon un axe sensiblement perpendiculaire à l'axe longitudinal du tube plongeur. Le dispositif étant utilisé de préférence tête en haut avec le tube sensiblement vertical, on peut ainsi obtenir un spray qui n'est pas vertical, et en particulier un spray horizontal qui facilite l'application du produit sur la peau en prévoyant par exemple un orifice de pulvérisation orienté à 90° par rapport à l'axe du tube.The spray orifice may open along an oblique axis with respect to the axis of the dip tube. The spray orifice may also open on an axis substantially perpendicular to the longitudinal axis of the dip tube. The device being used preferably head up with the substantially vertical tube, it is thus possible to obtain a spray which is not vertical, and in particular a horizontal spray which facilitates the application of the product to the skin by providing for example an orifice of spray oriented at 90 ° with respect to the axis of the tube.

Avantageusement, la zone déformable de la paroi 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 la pression. Le dispositif peut alors être utilisé plusieurs fois consécutivement.Advantageously, the deformable zone of the wall is shape memory, that is to say that it is configured to return to its initial shape by elastic return when the pressure ceases. The device can then be used several times consecutively.

La zone déformable peut présenter un profil sensiblement convexe dans sa position non déformée, notamment en forme de dôme, et un profil sensiblement concave dans sa position déformée. Cette configuration facilite le retour de la paroi en position convexe lorsque cesse la pression.The deformable zone may have a substantially convex profile in its undeformed position, particularly in the shape of a dome, and a substantially concave profile in its deformed position. This configuration facilitates the return of the wall in the convex position when the pressure ceases.

La paroi située en regard de la zone déformable peut être sensiblement plane.The wall facing the deformable zone may be substantially flat.

La zone déformable du réservoir peut être formée d'un matériau thermoplastique, notamment un polyéthylène, un polypropylène, un polyester téréphtalate, un polyéthylène naphtalate, un polyacrylonitrile, un polyoxyméthylène, un polychlorure de vinyle, ou un mélange de ces matériaux.The deformable zone of the reservoir may be formed of a thermoplastic material, in particular a polyethylene, a polypropylene, a polyester terephthalate, a polyethylene naphthalate, a polyacrylonitrile, a polyoxymethylene, a polyvinyl chloride, or a mixture of these materials.

Le dispositif peut comprendre un embout de pulvérisation fixé au réservoir qui comporte l'orifice de pulvérisation.The device may include a spray tip attached to the reservoir that includes the spray orifice.

Le dispositif de pulvérisation peut comporter un organe de fermeture apte à obturer l'orifice de pulvérisation.The spray device may comprise a closure member adapted to close the spray orifice.

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 a sample dose of a cosmetic product, especially a perfume.

  • les figures 1 à 6 illustrent des vues en perspective d'un mode de réalisation du dispositif de pulvérisation selon l'invention, dans différentes positions ;
  • la figure 7 représente partiellement en coupe axiale le dispositif de pulvérisation illustré à la figure 1 ; et
  • les figures 8 et 9 illustrent partiellement des variantes de réalisation du tube plongeur du dispositif de la figure 1.
The invention consists, apart from the arrangements set out above, in 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:
  • Figures 1 to 6 illustrate perspective views of an embodiment of the spraying device according to the invention, in different positions;
  • Figure 7 shows partially in axial section the spray device shown in Figure 1; and
  • FIGS. 8 and 9 partially illustrate alternative embodiments of the dip tube of the device of FIG. 1.

Le dispositif représenté en vue d'ensemble sur les figures 1 à 6 comprend un réservoir 10 à paroi déformable, contenant le produit P à distribuer et de l'air, sur lequel est monté un embout 20 comportant un orifice de pulvérisation 21. L'orifice de pulvérisation 21 est en communication avec l'intérieur du réservoir par l'intermédiaire d'un tube plongeur 30 d'axe longitudinal X.The device shown in a general view in FIGS. 1 to 6 comprises a reservoir 10 with a deformable wall, containing the product P to be dispensed and air, on which is mounted a nozzle 20 comprising a spray orifice 21. spray orifice 21 is in communication with the interior of the tank via a plunger tube 30 of longitudinal axis X.

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 peut par exemple être sous forme de sphère.According to the embodiment shown, the reservoir 10 is configured in the form of a drop of water, but it is obvious that it may have any other shape allowing the deformation of at least one of its walls. It can for example be in the form of a sphere.

Le réservoir 10 est obtenu par moulage, notamment par injection soufflage à partir d'une seule pièce, d'un matériau thermoplastique. Le réservoir est par exemple formé 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.The reservoir 10 is obtained by molding, in particular by injection blow molding from a single piece of a thermoplastic material. The reservoir is for example formed of a polyethylene, a polypropylene, a polyethylene terephthalate, a polyethylene naphthalate, a polyacrylonitrile, a polyoxymethylene, a polyvinyl chloride, or a mixture of these materials.

La paroi du réservoir 10 comprend une zone 11 de forme bombée qui est déformable lorsqu'on exerce une pression dessus. Cette paroi est à mémoire de forme de sorte qu'elle reprend sa position initiale lorsqu'on cesse d'exercer une pression dessus.The wall of the tank 10 comprises a zone 11 of convex shape which is deformable when pressure is exerted on it. This wall is shape memory so that it resumes its initial position when ceasing to exert pressure on it.

A l'opposé de cette zone 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 ailleurs, la paroi plane 12 sert également à poser le dispositif. La paroi plane 12 peut également facilement être décorée.Opposite this zone 11, the reservoir 10 has a flat wall 12. This configuration of the reservoir makes it easy to identify the area on which the user must exert pressure so that the operation of the device is made obvious. In addition, this configuration makes it easy to grasp the device between two fingers. Moreover, the flat wall 12 also serves to set the device. The flat wall 12 can also easily be decorated.

Le réservoir 10 se termine par un col ouvert 13, visible à la figure 7, sur lequel est monté de manière étanche l'embout de pulvérisation 20.The tank 10 terminates in an open neck 13, visible in FIG. 7, on which the spray tip 20 is sealingly mounted.

La forme extérieure de l'embout de pulvérisation 20 est telle que lorsque l'embout est fixé sur le col du réservoir, il forme l'extrémité de la goutte d'eau.The outer shape of the spray tip 20 is such that when the tip is attached to the neck of the tank, it forms the end of the drop of water.

L'embout de pulvérisation 20 comprend une jupe d'accrochage 24, cylindrique de révolution, qui coopère par encliquetage avec une gorge annulaire 14 formée sur la paroi externe du col 13 du réservoir.The spray tip 20 comprises a hooking skirt 24, cylindrical of revolution, which cooperates by snapping with an annular groove 14 formed on the outer wall of the neck 13 of the tank.

L'embout de pulvérisation 20 comprend également une jupe d'étanchéité 25, cylindrique de révolution, la jupe d'étanchéité étant concentrique à la jupe d'accrochage 24. La jupe d'étanchéité 25 est en appui étanche sur la surface interne du col 13 du récipient.The spray tip 20 also comprises a sealing skirt 25, cylindrical of revolution, the sealing skirt being concentric with the hooking skirt 24. The sealing skirt 25 bears tightly against the inner surface of the neck 13 of the container.

La jupe d'accrochage 24 et la jupe d'étanchéité 25 s'étendent parallèlement à l'axe longitudinal X du tube plongeur.The attachment skirt 24 and the sealing skirt 25 extend parallel to the longitudinal axis X of the plunger tube.

Une paroi 26, transversale à l'axe X, obture partiellement la jupe d'étanchéité 25 dans sa partie supérieure, la paroi transversale 26 étant traversée par un passage 27 qui débouche dans un conduit 28 d'axe longitudinal Y, perpendiculaire à l'axe X. Le conduit 28 est fermé à l'une de ses extrémités 28a, ouvert à l'autre de ses extrémités 28b pour recevoir une buse 40 dans laquelle est formé l'orifice de pulvérisation 21.A wall 26, transverse to the axis X, partially closes the sealing skirt 25 in its upper part, the transverse wall 26 being traversed by a passage 27 which opens into a conduit 28 of longitudinal axis Y, perpendicular to the X axis. The duct 28 is closed at one of its ends 28a, open at the other of its ends 28b to receive a nozzle 40 in which the spray orifice 21 is formed.

Le tube plongeur 30 est monté en force dans l'embout de pulvérisation 20. En particulier, la première extrémité 30a du tube plongeur est montée en force dans la jupe d'étanchéité 25. La seconde extrémité 30b du tube plongeur débouche sensiblement vers le fond du réservoir de manière à être immergée dans le produit à pulvériser lorsque le dispositif de pulvérisation est en position tête en haut.The plunger tube 30 is force-fitted into the spray nozzle 20. In particular, the first end 30a of the plunger tube is force-fitted into the sealing skirt 25. The second end 30b of the plunger tube opens substantially towards the bottom of the reservoir so as to be immersed in the spray material when the spray device is in the upward position.

Un orifice 31 est formé dans la paroi latérale du tube plongeur 30 pour permettre à l'air présent dans le réservoir 20 au-dessus du produit à pulvériser, lorsqu'il est comprimé, de s'introduire dans le tube plongeur en même temps que le produit remonte dans le tube, comme on l'a représenté à la figure 6.An orifice 31 is formed in the side wall of the plunger tube 30 to allow air in the reservoir 20 above the spraying product, when compressed, to be introduced into the plunger tube together with the product rises in the tube, as shown in Figure 6.

La position du passage d'air 31 est choisie en fonction de la forme du réservoir et de la quantité initiale de produit, de manière telle que, avant une première utilisation du dispositif, le passage d'air 31 soit à l'extérieur du produit, quelle que soit la position du réservoir.The position of the air passage 31 is chosen according to the shape of the tank and the initial quantity of product, so that, before a first use of the device, the air passage 31 is outside the product. regardless of the position of the tank.

En particulier, lorsque le dispositif est en position tête en haut, c'est-à-dire lorsque la seconde extrémité 30b du tube plongeur est en dessous de la première 30a, on voit sur les figures 1 et 2 que le niveau supérieur 100 du produit est en dessous du passage d'air 31. Lorsque le dispositif est en position tête en bas, c'est-à-dire lorsque la seconde extrémité 30b du tube plongeur est en dessus de la première extrémité 30a, on voit sur les figures 4 et 5 que le niveau supérieur 100 du produit est toujours en dessous du passage d'air 31. De même, lorsque le tube plongeur est horizontal comme on l'a représenté à la figure 3, le niveau supérieur 100 du produit est en dessous du passage d'air 31.In particular, when the device is in the head-up position, that is to say when the second end 30b of the plunger tube is below the first 30a, it can be seen in FIGS. 1 and 2 that the upper level 100 of the product is below the air passage 31. When the device is in the upside down position, that is to say when the second end 30b of the plunger tube is above the first end 30a, we see in the figures 4 and 5 that the upper level 100 of the product is always below the air passage 31. Similarly, when the dip tube is horizontal as shown in Figure 3, the upper level 100 of the product is below of the air passage 31.

En particulier, le passage d'air 31 est à l'extérieur du produit lorsque la zone déformable 11 est déformée à son maximum comme on l'a représenté à la figure 6.In particular, the air passage 31 is outside the product when the deformable zone 11 is deformed to its maximum as shown in FIG.

Selon un exemple particulier, si on prend un réservoir en forme de sphère, on place l'orifice d'air au centre de la sphère et on remplit le réservoir de produit d'un volume inférieur à la moitié du volume total du réservoir.In a particular example, if a sphere-shaped reservoir is taken, the air orifice is placed in the center of the sphere and the product reservoir is filled with a volume less than half the total volume of the reservoir.

Dans les positions illustrées sur les figures 1, 2 et 6, l'extrémité inférieure 30b du tube plongeur 30 est immergée de produit. Le produit peut alors être pulvérisé en pressant la paroi déformable 11 comme on l'a illustré à la figure 6. Le réservoir 10 passe alors d'une première position convexe correspondant à sa position non déformée, à une seconde position concave correspondant à sa position déformée. Le reste du réservoir n'est sensiblement pas déformé de sorte que, lorsque la paroi déformable 11 est déformée, le volume intérieur du réservoir diminue. L'air présent dans le réservoir est alors comprimé et une surpression est créée à l'intérieur du réservoir. Le produit est poussé à l'intérieur du tube plongeur, par son extrémité 30b en même temps que l'air s'y introduit, via le passage d'air 31, de sorte qu'un mélange produit-air est formé dans le tube plongeur. Le mélange obtenu est ensuite pulvérisé au travers de l'orifice 21.In the positions illustrated in Figures 1, 2 and 6, the lower end 30b of the dip tube 30 is immersed in product. The product can then be pulverized by pressing the deformable wall 11 as illustrated in FIG. 6. The reservoir 10 then passes from a first convex position corresponding to its undistorted position, to a second concave position corresponding to its position. distorted. The remainder of the reservoir is substantially not deformed so that when the deformable wall 11 is deformed, the internal volume of the reservoir decreases. The air in the tank is then compressed and an overpressure is created inside the tank. The product is pushed inside the dip tube, by its end 30b at the same time as the air is introduced through the air passage 31, so that a product-air mixture is formed. in the dip tube. The mixture obtained is then sprayed through the orifice 21.

Lorsque la paroi reprend sa forme initiale, de l'air entre alors dans le réservoir, notamment par l'orifice de pulvérisation 21. 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 original shape, air then enters the reservoir, in particular through the spray orifice 21. If there is product remaining inside the reservoir, it is again possible to create an overpressure by deforming the actuation wall and thus spray another dose of product.

Dans les positions illustrées sur les figures 3 à 5, l'extrémité inférieure 30b du tube plongeur n'est plus immergée de produit. Etant donné que le passage d'air 31 est aussi à l'extérieur du produit, si l'utilisateur presse la paroi déformable 11, seul de l'air sortira. Il saura alors qu'il doit positionner différemment le réservoir pour pouvoir pulvériser du produit.In the positions illustrated in Figures 3 to 5, the lower end 30b of the dip tube is no longer immersed product. Since the air passage 31 is also outside the product, if the user presses the deformable wall 11, only air will come out. He will then know that he must position the tank differently to be able to spray product.

Selon l'invention, l'extrémité inférieure 30b du tube plongeur et le passage d'air 31 n'étant jamais tous les deux immergés de produit, l'utilisateur ne pourra jamais faire sortir le produit sous forme d'un jet. Soit, le produit sera pulvérisé sous forme d'un spray grâce au mélange air-produit, soit de l'air seul sortira.According to the invention, the lower end 30b of the dip tube and the air passage 31 are never both immersed product, the user can never get out the product in the form of a jet. Either the product will be sprayed in the form of a spray thanks to the air-product mixture, or only air will come out.

Dans l'exemple qui vient d'être décrit, le passage d'air est un trou de section transversale circulaire. Il est bien évident que le passage d'air peut être formé par un trou de toute autre forme, par exemple un trou de section transversale ovale, triangulaire ou polygonale.In the example just described, the air passage is a hole of circular cross section. It is obvious that the air passage may be formed by a hole of any other shape, for example a hole of oval, triangular or polygonal cross section.

En outre, le tube plongeur peut comporter plusieurs passages d'air 31. Le tube plongeur peut par exemple comporter deux passages d'air situés en regard l'un de l'autre comme on l'a illustré à la figure 8 ou encore deux passages d'air 31 situés à deux hauteurs différentes comme on l'a représenté à la figure 9. Dans tous les cas, tous les passages d'air devront rester à l'extérieur du produit, quelle que soit la position du réservoir.In addition, the dip tube may comprise several air passages 31. The dip tube may for example comprise two air passages located opposite one another as illustrated in FIG. 8 or two air passages 31 located at two different heights as shown in Figure 9. In all cases, all air passages must remain outside the product, regardless of the position of the tank.

Pour pouvoir stocker le dispositif de pulvérisation entre deux utilisations, l'embout de pulvérisation 20 peut comporter un organe de fermeture 50, sous forme par exemple d'un bouchon qui vient se fixer à l'extérieur de la buse 40 comme on le voit à la figure 7.In order to be able to store the spraying device between two uses, the spray tip 20 may comprise a closure member 50, under for example, a plug that is attached to the outside of the nozzle 40 as seen in Figure 7.

En variante, on peut prévoir que l'orifice de pulvérisation est obturé avant une première utilisation, par exemple par un film thermoscellé, qui ne peut être repositionné après avoir été retiré. Un tel arrangement est adapté aux dispositifs de pulvérisation à usage unique.Alternatively, it can be provided that the spray orifice is closed before a first use, for example by a heat-sealed film, which can not be repositioned after being removed. Such an arrangement is suitable for single use spraying devices.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
