Description

La présente invention se rapporte à un dispositif de pulvérisation et à une utilisation de ce dispositif.The present invention relates to a spraying device and to a use of this device.

Plus particulièrement, l'invention se rapporte à un dispositif de pulvérisation manuel conforme à la revendication 1.More particularly, the invention relates to a manual spray device according to claim 1.

Le document US-A-6 145 712 décrit un exemple d'un dispositif de pulvérisation, dans laquelle la face frontale de la buse de pulvérisation comporte un unique trou central. Le document WO03/02436 montre un dispositif de pulvérisation à haute pression, jusqu'à 500 bars, et prévoit un poussoir déplaçable perpendiculairement à l'axe du réservoir pour déplacer un organe de blocage et libérer le déplacemenrt d'une buse selon l'axe du réservoir sous l'action d'un ressort. D'autre part, le document EP1698399 décrit une buse de pulvérisation dont la paroi frontale est bombée et comporte des trous divergeant les uns par rapport aux autres. Le document EP613836 montre une paroi pourvue de pores placée sur un boîtier distant du poussoir. Le document WO02/01981 décrit une saillie creuse s'étendant depuis le poussoir et comportant des trous s'étendant transversalement par rapport à la saillie. En outre, le document JP2002186882 montre une buse de pulvérisation dont la paroi frontale comporte des ouvertures de formes variées, notamment des trous.The document US-A-6,145,712 describes an example of a spray device, in which the front face of the spray nozzle has a single central hole. The document WO03/02436 shows a high pressure spraying device, up to 500 bar, and provides a pusher that can be moved perpendicularly to the axis of the tank to move a blocking member and release the movement of a nozzle along the axis of the tank under the action of a spring. On the other hand, the document EP1698399 describes a spray nozzle whose front wall is curved and has holes diverging from each other. The document EP613836 shows a wall provided with pores placed on a casing remote from the pusher. The document WO02/01981 describes a hollow projection extending from the pusher and having holes extending transversely of the projection. Additionally, the document JP2002186882 shows a spray nozzle whose front wall has openings of various shapes, including holes.

Dans les dispositifs de pulvérisation de ce type, les buses de pulvérisation, qui sont classiquement montées sur des pompes ou sur des valves de pulvérisation, présentent l'inconvénient d'entraîner une grande dispersion du diamètre des gouttelettes de produit fluide pulvérisé.In spray devices of this type, the spray nozzles, which are conventionally mounted on pumps or on spray valves, have the drawback of causing a large dispersion of the diameter of the droplets of fluid sprayed.

En effet, dans les buses de pulvérisation de dispositif de ce type, le fractionnement du produit fluide en fines gouttelettes est obtenu par un phénomène dynamique particulièrement difficile à maîtriser, consistant généralement à créer un tourbillon dans la chambre intérieure de la buse et à fractionner le produit fluide en fines gouttelettes lors de sa sortie à très haute vitesse par le trou central.Indeed, in device spray nozzles of this type, the splitting of the fluid product into fine droplets is obtained by a dynamic phenomenon that is particularly difficult to control, generally consisting of creating a vortex in the inner chamber of the nozzle and splitting the fluid product in fine droplets when it exits at very high speed through the central hole.

A titre d'exemple, on a pu mesurer que, pour une buse de pulvérisation du type susmentionné dont la chambre intérieure reçoit une solution alcoolique sous une pression de 5 bars depuis une pompe manuelle ou une valve, et pour un trou central de la buse présentant un diamètre de 0,3 mm, le produit pulvérisé est constitué de gouttelettes ayant des diamètres compris entre 5 µm 300 µm.By way of example, it has been possible to measure that, for a spray nozzle of the aforementioned type whose inner chamber receives an alcoholic solution under a pressure of 5 bars from a manual pump or a valve, and for a central hole in the nozzle having a diameter of 0.3 mm, the sprayed product consists of droplets having diameters between 5 µm and 300 µm.

Cette dispersion peut s'avérer indésirable lorsque l'on souhaite pulvériser des gouttelettes de tailles sensiblement homogènes. Par exemple, on peut souhaiter pulvériser des gouttelettes de petite taille pour l'inhalation de traitements médicamenteux des bronches, ou encore, on peut souhaiter pulvériser des gouttes de plus grande taille pour des applications cosmétiques ou de parfumerie, pour que les gouttelettes pénètrent le moins possible dans les bronches de l'utilisateur.This dispersion can prove to be undesirable when it is desired to spray droplets of substantially homogeneous sizes. For example, one may wish to spray small droplets for inhalation of bronchial drug treatments, or one may wish to spray larger droplets for cosmetic or perfumery applications, so that the droplets penetrate less. possible in the bronchi of the user.

De plus, les gouttelettes de tailles très différentes suivent des trajectoires également très différentes, ce qui est néfaste pour une application contrôlée du produit pulvérisé. Par exemple, lors de la pulvérisation d'un parfum vers la peau d'un utilisateur, des gouttelettes de trop grande taille peuvent tomber sur les vêtements de l'utilisateur au lieu d'être projetées sur la peau, risquant de provoquer des tâches indélébiles.In addition, the droplets of very different sizes also follow very different trajectories, which is harmful for a controlled application of the sprayed product. For example, when spraying a perfume onto a user's skin, droplets that are too large may fall on the user's clothing instead of being projected onto the skin, risking causing permanent stains. .

La présente invention a notamment pour but de pallier ces inconvénients.The object of the present invention is in particular to overcome these drawbacks.

A cet effet, l'invention propose un dispositif de pulvérisation manuel conforme à la revendication 1.To this end, the invention proposes a manual spraying device according to claim 1.

On notera que, le terme de diamètre n'implique pas nécessairement que cette section soit circulaire. Ainsi, les trous de la face frontale pourraient le cas échéant présenter une section polygonale, par exemple carrée, sans sortir du cadre de la présente invention. Dans ce cas, le diamètre susmentionné serait le diamètre équivalent du trou, c'est-à-dire le diamètre d'un trou circulaire présentant une section de même surface que le trou polygonal. Si les trous ne sont pas de section constante sur leur longueur, le diamètre en question est le diamètre de la section minimale des trous.It will be noted that the term diameter does not necessarily imply that this section is circular. Thus, the holes of the front face could if necessary have a polygonal section, for example square, without departing from the scope of the present invention. In this case, the aforementioned diameter would be the equivalent diameter of the hole, that is to say the diameter of a circular hole having a section of the same surface as the polygonal hole. If the holes are not of constant section along their length, the diameter in question is the diameter of the minimum section of the holes.

Grâce aux dispositions exposées ci-dessus, on maîtrise la taille des gouttelettes pulvérisées par le dispositif de pulvérisation et on assure une bonne homogénéité de cette taille des gouttelettes.Thanks to the arrangements described above, the size of the droplets sprayed by the spraying device is controlled and good homogeneity of this size of the droplets is ensured.

Par ailleurs, les dispositions précitées permettent également de s'affranchir au moins partiellement des différences de pression avec lesquelles le produit fluide est alimenté dans la chambre intérieure de la buse de pulvérisation, puisque l'expérience montre que la taille des gouttelettes obtenues grâce à la présente invention est peu dépendante de cette pression (les différences de pression en question peuvent provenir par exemple de différences dans la force d'actionnement d'un utilisateur si le produit fluide est alimenté grâce à une pompe manuelle, ou encore, lorsque le produit fluide est alimenté grâce à une valve à partir d'un réservoir de produit sous pression, les différences de pression en question peuvent provenir du fait que le réservoir a déjà été partiellement vidé par de précédentes utilisations du dispositif de pulvérisation).Furthermore, the aforementioned arrangements also make it possible to at least partially overcome the pressure differences with which the fluid product is fed into the inner chamber of the spray nozzle, since experience shows that the size of the droplets obtained thanks to the present invention is not very dependent on this pressure (the pressure differences in question can come, for example, from differences in the actuating force of a user if the fluid product is supplied by means of a manual pump, or even, when the fluid product is supplied by means of a valve from a tank of product under pressure, the pressure differences in question may come from the fact that the tank has already been partially emptied by previous uses of the spraying device).

Par ailleurs, l'invention vise à améliorer la maîtrise de la forme de l'aérosol obtenu en sortie de la buse de pulvérisation tout en permettant une réalisation simplifiée des trous calibrés.Furthermore, the invention aims to improve control of the shape of the aerosol obtained at the outlet of the spray nozzle while allowing simplified production of the calibrated holes.

A cet effet, selon l'invention, la paroi frontale est déformable élastiquement entre un état de repos, dans lequel ladite paroi frontale est plane, et un état d'actionnement lorsque du produit fluide sous pression est transféré dans la chambre intérieure, dans lequel ladite paroi frontale présente une convexité tournée vers l'extérieur.To this end, according to the invention, the front wall is elastically deformable between a state of rest, in which said front wall is flat, and a state of actuation when fluid under pressure is transferred into the inner chamber, in which said front wall has a convexity facing outward.

Ainsi, à l'état de repos, les trous peuvent être réalisés de manière simple dans la paroi frontale plane, chaque trou pouvant présenter un axe qui s'étend dans un plan parallèle à un axe central perpendiculaire à la paroi frontale. A l'état d'actionnement, lorsque du produit fluide est pulvérisé, les axes des trous s'écartent par rapport à l'axe central de sorte à présenter une divergence vers l'extérieur et le produit fluide peut être pulvérisé sous la forme d'un aérosol présentant un angle d'ouverture élevé.Thus, in the state of rest, the holes can be simply made in the flat front wall, each hole possibly having an axis which extends in a plane parallel to a central axis perpendicular to the front wall. In the actuation state, when the fluid product is sprayed, the axes of the holes deviate from the central axis so as to have an outward divergence and the fluid product can be sprayed in the form of an aerosol having a high opening angle.

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the various figures, the same references designate identical or similar elements.

La figure 1 représente un dispositif de pulvérisation 1 adapté pour pulvériser un produit fluide non gazeux 2 contenu dans un réservoir 3. Le produit fluide en question peut être un produit liquide ou semi-liquide, par exemple un produit pharmaceutique, un produit cosmétique, un produit de parfumerie ou autre. La viscosité dynamique du produit fluide 2 est généralement inférieure à 50 cps (centipoises) à 20 deg. C.There figure 1 represents a spraying device 1 suitable for spraying a non-gaseous fluid product 2 contained in a reservoir 3. The fluid product in question can be a liquid or semi-liquid product, for example a pharmaceutical product, a cosmetic product, a perfumery product Or other. The dynamic viscosity of the fluid product 2 is generally less than 50 cps (centipoise) at 20 deg. vs.

Le dispositif de pulvérisation 1 comporte en outre un dispositif de distribution 4 qui est fixé de façon connue à un col 5 du réservoir 3 à l'extrémité supérieure dudit réservoir.The spraying device 1 further comprises a dispensing device 4 which is fixed in known manner to a neck 5 of the reservoir 3 at the upper end of the said reservoir.

Le dispositif de distribution 4 peut par exemple être une pompe manuelle de pulvérisation ou encore une valve de pulvérisation, auquel cas le réservoir 3 est sous pression.The dispensing device 4 can for example be a manual spray pump or even a spray valve, in which case the reservoir 3 is under pressure.

Dans tous les cas, le dispositif de distribution 4 comporte une entrée 6 de produit fluide, orientée vers le bas, qui communique avec le fond du réservoir 3 par l'intermédiaire d'un tube plongeur 7, et une tige d'actionnement creuse 8 qui fait saillie vers le haut. Un bouton poussoir 9 est emboîté à l'extrémité supérieure de la tige d'actionnement 8, et sert à la fois à l'actionnement du dispositif de distribution 4 et à la sortie du produit fluide pulvérisé, sortie qui s'effectue au travers de la tige actionnement 8, selon la flèche 10 représentée sur la figure 2.In all cases, the dispensing device 4 comprises a fluid product inlet 6, facing downwards, which communicates with the bottom of the reservoir 3 via a dip tube 7, and a hollow actuating rod 8 which protrudes upwards. A push button 9 is fitted to the upper end of the rod actuation 8, and is used both for actuating the dispensing device 4 and for the outlet of the sprayed fluid product, an outlet which takes place through the actuation rod 8, according to the arrow 10 represented on the picture 2 .

On notera que le dispositif de distribution représenté en figure 1 pourrait, en variante, être utilisé en position inversée, c'est-à-dire le fond du réservoir 3 orienté vers le haut. Dans ce cas, le dispositif de distribution 4 ne comporterait pas de tube plongeur 7.It will be noted that the dispensing device shown in figure 1 could, as a variant, be used in the inverted position, that is to say the bottom of the reservoir 3 facing upwards. In this case, the dispensing device 4 would not include a dip tube 7.

Comme représenté sur la figure 2, le poussoir 9 peut par exemple être moulé d'une seule pièce en matière plastique, notamment un polyoléfine, par exemple en polypropylène ou autre.As shown on the figure 2 , the pusher 9 can for example be molded in a single piece of plastic material, in particular a polyolefin, for example polypropylene or the like.

Le poussoir 9 comporte une paroi supérieure 11 sensiblement horizontale et une jupe 12 sensiblement cylindrique et verticale, qui s'étend à partir de la périphérie de la paroi supérieure 11.The pusher 9 comprises a substantially horizontal upper wall 11 and a substantially cylindrical and vertical skirt 12, which extends from the periphery of the upper wall 11.

Par ailleurs, le poussoir 9 comporte en outre un puits central 13 qui s'étend verticalement vers le bas à partir de la paroi supérieure 11, au centre de la paroi latérale 12. L'extrémité supérieure de la tige d'actionnement 8 est emboîtée dans le puits central 13.Furthermore, the pusher 9 further comprises a central well 13 which extends vertically downwards from the upper wall 11, in the center of the side wall 12. The upper end of the actuating rod 8 is fitted in the central well 13.

A l'extrémité supérieure du puits central 13 est ménagé un passage latéral 14 qui communique avec un logement de réception de buse 15 de forme sensiblement cylindrique, s'étendant sensiblement horizontalement selon un axe central X et débouchant vers l'extérieur du poussoir 9.At the upper end of the central well 13 is formed a lateral passage 14 which communicates with a nozzle receiving housing 15 of substantially cylindrical shape, extending substantially horizontally along a central axis X and opening towards the outside of the pusher 9.

Comme représenté sur les figures 2 et 3, une buse de pulvérisation 16 est emboîtée à force dans le logement de buse 15. Cette buse de pulvérisation 16 peut être formée d'une seule pièce en matière plastique, par exemple en polybutylènetérephtalate (PBT), en copolymère cyclo-oléfine (COC) ou encore en polyacétal (POM) et comporte :

  • une paroi frontale perforée 17,
  • et une paroi latérale annulaire 18 qui présente une forme cylindrique (de révolution ou non) qui s'étend selon l'axe X à l'intérieur du logement de buse 15, à partir de la périphérie de la paroi frontale 17.
As shown on the figure 2 And 3 , a spray nozzle 16 is fitted by force in the nozzle housing 15. This spray nozzle 16 can be formed from a single piece of plastic material, for example polybutylene terephthalate (PBT), cyclo-olefin copolymer (COC) or polyacetal (POM) and includes:
  • a perforated front wall 17,
  • and an annular side wall 18 which has a cylindrical shape (of revolution or not) which extends along the X axis inside the nozzle housing 15, from the periphery of the front wall 17.

De façon connue en soi, la paroi latérale 18 de la buse de pulvérisation 16 peut comporter, à son extrémité opposée à la paroi frontale 17 un gaudron annulaire 19 qui fait saillie radialement vers l'extérieur et qui pénètre dans la matière du poussoir 9 pour ancrer la buse de pulvérisation 16 dans le logement de buse 15.In a manner known per se, the side wall 18 of the spray nozzle 16 may comprise, at its end opposite the front wall 17, an annular gaudron 19 which projects radially outwards and which penetrates into the material of the pusher 9 to anchor the spray nozzle 16 in the nozzle housing 15.

La buse de pulvérisation 16 délimite, avec le poussoir 9, une chambre intérieure 20 qui communique avec le passage 14 susmentionné et qui reçoit le produit fluide à pulvériser lors de l'actionnement du dispositif de distribution 4. Eventuellement, comme on peut le voir sur la figure 2, le poussoir 9 peut comporter un noyau 21 qui fait saillie à l'intérieur de la paroi latérale 18 de la buse de pulvérisation pour limiter le volume de cette chambre intérieure 20.The spray nozzle 16 delimits, with the pusher 9, an inner chamber 20 which communicates with the aforementioned passage 14 and which receives the fluid product to be sprayed when the dispensing device 4 is actuated. Optionally, as can be seen in there figure 2 , the pusher 9 may include a core 21 which protrudes inside the side wall 18 of the spray nozzle to limit the volume of this inner chamber 20.

Comme représenté plus en détail sur la figure 3, la paroi frontale 17 de la buse de pulvérisation comporte une pluralité de trous 22 qui sont répartis sur la surface de ladite face frontale. Les trous 22 peuvent être au nombre de 10 à 1000 par exemple. Le diamètre de chaque trou 22 est généralement compris entre 1 et 100 µm, tous les trous 22 étant sensiblement de même diamètreAs shown in more detail on the picture 3 , the front wall 17 of the spray nozzle has a plurality of holes 22 which are distributed over the surface of said front face. The holes 22 may number from 10 to 1000 for example. The diameter of each hole 22 is generally between 1 and 100 μm, all the holes 22 being substantially of the same diameter

Plus généralement, le diamètre de chaque trou 22 ne diffère pas de la valeur moyenne des diamètres des différents trous 22 de plus de 20% et avantageusement, le diamètre de chaque trou 22 ne diffère pas de ladite valeur moyenne de plus de 10%.More generally, the diameter of each hole 22 does not differ from the mean value of the diameters of the various holes 22 by more than 20% and advantageously, the diameter of each hole 22 does not differ from said mean value by more than 10%.

Les trous 22 peuvent être de forme sensiblement cylindrique à section circulaire, mais ils pourraient le cas échéant présenter une section polygonale, par exemple carrée, auquel cas le diamètre susmentionné serait le diamètre équivalent du trou, c'est-à-dire le diamètre d'un trou circulaire présentant une section de même surface que le trou polygonal.The holes 22 can be of substantially cylindrical shape with a circular section, but they could if necessary have a polygonal section, for example square, in which case the aforementioned diameter would be the equivalent diameter of the hole, that is to say the diameter d 'a circular hole having a section of the same surface as the polygonal hole.

Le diamètre des trous 22 peut être choisi en fonction du produit fluide à pulvériser, et par exemple :

  • le diamètre moyen des trous 22 peut être compris entre 1 et 3 2. µm (micromètres) pour la pulvérisation de produits pharmaceutiques de traitement des poumons
  • le diamètre moyen des trous 22 peut être compris entre 3 et 10 µm pour la pulvérisation de produits pharmaceutiques de traitement de la trachée et des bronches,
  • le diamètre moyen des trous 22 peut être compris entre 10 et 60 µm pour la pulvérisation de produits pharmaceutiques de traitement du nez, de la bouche ou de la gorge,
  • le diamètre moyen des trous 22 peut être compris entre 50 et 100 µm pour la pulvérisation de produits pharmaceutiques de traitement de la peau ou pour la pulvérisation de produits de maquillage,
  • le diamètre moyen des trous 22 peut être compris entre 15 et 60 µm pour la pulvérisation de produits de parfumerie,
  • le diamètre moyen des trous 22 peut être compris entre 20 et 70 µm pour la pulvérisation de produits cosmétiques de soin de la peau,
The diameter of the holes 22 can be chosen according to the fluid product to be sprayed, and for example:
  • the average diameter of the holes 22 can be between 1 and 3 2. μm (micrometers) for spraying lung treatment pharmaceuticals
  • the average diameter of the holes 22 can be between 3 and 10 μm for the spraying of pharmaceutical products for the treatment of the trachea and the bronchi,
  • the average diameter of the holes 22 can be between 10 and 60 μm for the spraying of pharmaceutical products for the treatment of the nose, mouth or throat,
  • the average diameter of the holes 22 can be between 50 and 100 μm for the spraying of pharmaceutical products for treating the skin or for the spraying of make-up products,
  • the average diameter of the holes 22 can be between 15 and 60 μm for the spraying of perfumery products,
  • the average diameter of the holes 22 can be between 20 and 70 μm for the spraying of cosmetic skin care products,

La paroi frontale 17 peut présenter une forme bombée de concavité tournée vers l'intérieur, comme dans l'exemple représenté sur la figure 3, mais ladite paroi frontale peut être plate ou présenter tout autre forme souhaitée.The front wall 17 may have a domed shape with a concavity turned inwards, as in the example shown in the picture 3 , but said front wall may be flat or have any other desired shape.

Par ailleurs, la paroi frontale 17 peut présenter une épaisseur e comprise généralement entre 0,08 et 1,5 mm, notamment entre 0,2 et 0,4 mm.Furthermore, the front wall 17 may have a thickness e generally between 0.08 and 1.5 mm, in particular between 0.2 and 0.4 mm.

Les trous 22 peuvent présenter une section constante, comme dans l'exemple représenté, mais les trous 22 pourraient le cas échéant présenter des parties évasées vers l'intérieur et/ou vers l'extérieur, auquel cas la longueur des trous 22 à prendre en compte serait la longueur dans laquelle ces trous présentent une section constante et le diamètre à prendre en compte serait le diamètre de la section minimale. La longueur des trous 22 dans leur partie à section constante, est généralement comprise entre 0,08 et 0,5 mm, avantageusement entre 0,08 et 0,3 mm, et plus avantageusement encore entre 0,08 et 0,2 mm, notamment égale à environ 0,1 mm.The holes 22 can have a constant section, as in the example shown, but the holes 22 could if necessary have parts flared inwards and/or outwards, in which case the length of the holes 22 to be taken into account would be the length in which these holes have a constant section and the diameter to be taken into account would be the diameter of the minimum section. The length of the holes 22 in their constant section part is generally between 0.08 and 0.5 mm, advantageously between 0.08 and 0.3 mm, and even more advantageously between 0.08 and 0.2 mm, in particular equal to about 0.1 mm.

Comme représenté sur la figure 2, lorsqu'un utilisateur appuie sur le poussoir 9, celui-ci actionne le dispositif de distribution 4, qui alimente la chambre intérieure 20 de la buse en produit fluide sous pression, à une pression généralement inférieure à 7 bars, par exemple de l'ordre de 5 bars. Le produit fluide est expulsé au travers des trous calibrés 22 de la paroi frontale 17, ce qui produit un aérosol 23 de fines gouttelettes de taille relativement homogène et peu dépendante de la valeur exacte de la pression du produit fluide dans la chambre intérieure 20.As shown on the picture 2 , when a user presses the pusher 9, the latter actuates the dispensing device 4, which supplies the inner chamber 20 of the nozzle with fluid under pressure, at a pressure generally less than 7 bar, for example 5 bar order. The fluid product is expelled through the calibrated holes 22 of the front wall 17, which produces an aerosol 23 of fine droplets of relatively homogeneous size and little dependent on the exact value of the pressure of the fluid product in the interior chamber 20.

Dans le mode de réalisation représenté sur les figures 4 et 5, la buse de pulvérisation 16 diffère de la buse de pulvérisation précédemment décrite en ce que la paroi frontale 17b est déformable élastiquement entre un état de repos représenté sur la figure 4 et un état d'actionnement représenté sur la figure 5, lorsque du produit fluide sous pression est transféré dans la chambre intérieure 20.In the embodiment shown in the figures 4 and 5 , the spray nozzle 16 differs from the spray nozzle previously described in that the front wall 17b is elastically deformable between a state of rest shown on the figure 4 and an actuation state shown on the figure 5 , when fluid under pressure is transferred into the inner chamber 20.

En particulier, dans l'état de repos, la paroi frontale 17b s'étend dans un plan perpendiculaire à l'axe central X. Et dans l'état d'actionnement, la paroi frontale 17b présente une convexité tournée vers l'extérieur de sorte, par exemple, à présenter une forme de calotte sphérique.In particular, in the state of rest, the front wall 17b extends in a plane perpendicular to the central axis X. And in the state of actuation, the front wall 17b has a convexity facing outward from so, for example, to have a spherical cap shape.

Comme représenté sur les figures 4 et 5, à l'état de repos, la paroi frontale 17b est plane. Cette disposition permet de réaliser de manière simple les trous 22 présentant un axe qui s'étend, par exemple, selon une normale à la paroi frontale 17b, parallèlement à l'axe central X. Lorsqu'un utilisateur appuie sur le poussoir 9, du produit fluide sous pression est transféré dans la chambre intérieure 20 exerçant une force sur la paroi frontale 17b de sorte à la faire passer dans l'état d'actionnement. Les axes des trous 22 s'écartent par rapport à l'axe central X de sorte à présenter une divergence vers l'extérieur. Le produit fluide est expulsé au travers des trous 22 divergeant de la paroi frontale 17b, ce qui produit un aérosol 23 de fines gouttelettes de taille relativement homogène, l'aérosol 23 étant sensiblement conique avec un angle de cône élevé.As shown on the figures 4 and 5 , in the rest state, the front wall 17b is flat. This arrangement makes it possible to produce in a simple manner the holes 22 having an axis which extends, for example, along a normal to the front wall 17b, parallel to the central axis X. When a user presses the pusher 9, the fluid product under pressure is transferred into the inner chamber 20 exerting a force on the front wall 17b so as to bring it into the actuation state. The axes of the holes 22 deviate with respect to the central axis X so as to present an outward divergence. The fluid product is expelled through the holes 22 diverging from the front wall 17b, which produces an aerosol 23 of fine droplets of relatively homogeneous size, the aerosol 23 being substantially conical with a high cone angle.

Sur les figures 4 et 5, la paroi latérale 18 est une pièce distincte du poussoir 9, solidarisée avec le poussoir 9, et la paroi frontale 17b venue de matière avec la paroi latérale 18 est réalisée dans le même matériau que la paroi latérale 18. Pour permettre le passage de l'état de repos à l'état d'actionnement, on prévoit que la paroi frontale 17b présente une épaisseur e comprise entre 0,05 et 0,10 mm.On the figures 4 and 5 , the side wall 18 is a separate piece from the pusher 9, integral with the pusher 9, and the front wall 17b made in one piece with the side wall 18 is made of the same material as the side wall 18. To allow the passage of the state of rest in the actuation state, provision is made for the front wall 17b to have a thickness e of between 0.05 and 0.10 mm.

La réalisation de la paroi frontale 17b déformable élastiquement selon le deuxième mode de réalisation peut être prévue de manière complémentaire ou indépendante de la réalisation précédemment décrite dans laquelle tous les trous 22 sont sensiblement de même diamètre, compris entre 1 et 100 µm, et le diamètre de chaque trou 22 ne diffère pas de la valeur moyenne des diamètres des différents trous 22 de plus de 20%.The embodiment of the elastically deformable front wall 17b according to the second embodiment can be provided in a complementary or independent manner to the embodiment previously described in which all the holes 22 are substantially of the same diameter, between 1 and 100 μm, and the diameter of each hole 22 does not differ from the average value of the diameters of the different holes 22 by more than 20%.

En variante représentée sur les figures 6 et 7, on peut prévoir que la paroi latérale 18a soit formée d'une seule pièce avec le poussoir 9. La paroi frontale 17c peut ainsi être réalisée d'une seule pièce avec le poussoir 9 et être dans le même matériau que le poussoir 9. Le noyau 21 peut alors être une pièce rapportée et solidarisée au poussoir 9 de manière appropriée.As a variant shown on the figures 6 and 7 , provision can be made for the side wall 18a to be formed in one piece with the pusher 9. The front wall 17c can thus be made in one piece with the pusher 9 and be made of the same material as the pusher 9. The core 21 can then be an added piece and secured to pusher 9 in an appropriate manner.

Comme représenté sur les figures 6 et 7, on peut prévoir que la paroi frontale 17c soit déformable. Pour ce faire, la paroi frontale 17c peut présenter une épaisseur comprise entre 0,10 et 0,20 mm. On pourrait toutefois prévoir que la paroi frontale 17c présente uniquement une forme plane.As shown on the figures 6 and 7 , provision can be made for the front wall 17c to be deformable. To do this, the front wall 17c may have a thickness of between 0.10 and 0.20 mm. However, provision could be made for the front wall 17c to have only a planar shape.

La variante de réalisation des figures 8 et 9 est similaire à la variante des figures 2 et 3, et ne sera donc pas décrit à nouveau en détail. Dans la variante des figures 8 et 9, la buse de pulvérisation 16 diffère de la buse de pulvérisation précédemment décrite par le fait que la paroi frontale 17a est réalisée en un matériau différent de la paroi latérale 18 de la buse, la paroi latérale 18 étant une pièce distincte du poussoir 9, solidarisée avec le poussoir 9.The alternative embodiment of figures 8 and 9 is similar to the variant of figure 2 And 3 , and will therefore not be described again in detail. In the variant of figures 8 and 9 , the spray nozzle 16 differs from the spray nozzle previously described in that the front wall 17a is made of a different material from the side wall 18 of the nozzle, the side wall 18 being a separate part from the pusher 9, secured with button 9.

En variante représentée sur la figure 10, on peut prévoir que la paroi frontale 17a soit solidarisée avec la paroi latérale 18a formée d'une seule pièce avec le poussoir 9.As a variant shown on the figure 10 , it is possible to provide that the front wall 17a is secured to the side wall 18a formed in one piece with the pusher 9.

Par exemple, la paroi frontale 17a peut être réalisée en un matériau choisi parmi le silicium, le verre, les métaux et leurs alliages, les céramiques ou les polymères, tandis que la paroi latérale 18 est réalisée en matière plastique comme dans l'exemple précédent, ladite paroi latérale 18 pouvant être surmoulée sur le pourtour de la paroi frontale 17a.For example, the front wall 17a can be made of a material chosen from among silicon, glass, metals and their alloys, ceramics or polymers, while the side wall 18 is made of plastic as in the previous example. , said side wall 18 being able to be molded over the periphery of the front wall 17a.

Dans la variante des figures 8 et 9, la paroi frontale 17a est plane.In the variant of figures 8 and 9 , the front wall 17a is flat.

Par ailleurs, dans une autre variante, la paroi frontale 17a peut être déformable. Par exemple, la paroi frontale 17a peut être réalisée sous la forme d'un complexe comprenant au moins une couche de polymère et éventuellement une couche de matériau métallique. Le complexe peut présenter une épaisseur comprise entre 0,025 et 0,120 mm.Moreover, in another variant, the front wall 17a can be deformable. For example, the front wall 17a can be produced in the form of a complex comprising at least one layer of polymer and optionally a layer of metallic material. The complex may have a thickness of between 0.025 and 0.120 mm.

A titre d'exemples non limitatifs, le complexe peut comprendre :

  • une couche de polyester, d'une épaisseur de 0,025 mm, et une enduction thermocollante permettant le collage de la paroi frontale 17a sur la paroi latérale 18, ou
  • une couche de polyester, d'une épaisseur de 0,025 mm, et une couche de polyéthylène, d'une épaisseur de 0,020 mm, permettant le soudage de la paroi frontale 17a sur la paroi latérale 18, ou
  • une couche de polyester, d'une épaisseur de 0,025 mm, et une couche de polypropylène, d'une épaisseur de 0,020 mm, ou
  • une couche de polyester, d'une épaisseur de 0,025 mm, une couche d'aluminium, d'une épaisseur de 0,008 mm, et une couche de polyéthylène, d'une épaisseur de 0,040 mm.
By way of non-limiting examples, the complex may comprise:
  • a layer of polyester, with a thickness of 0.025 mm, and a heat-sealing coating allowing the bonding of the front wall 17a to the side wall 18, or
  • a layer of polyester, with a thickness of 0.025 mm, and a layer of polyethylene, with a thickness of 0.020 mm, allowing the welding of the front wall 17a on the side wall 18, or
  • a layer of polyester, with a thickness of 0.025 mm, and a layer of polypropylene, with a thickness of 0.020 mm, or
  • a polyester layer, 0.025 mm thick, an aluminum layer, 0.008 mm thick, and a polyethylene layer, 0.040 mm thick.

Dans la variante représentée sur les figures 11 à 13, de manière complémentaire ou indépendante de la réalisation de la paroi frontale 17 déformable élastiquement, la chaque trou 22 de la paroi frontale 17 de la buse de pulvérisation s'étend selon un axe X2 incliné par rapport à la normale X1 à ladite paroi frontale au niveau dudit trou 22. L'axe X2 et la normale X1 définissent un plan sensiblement tangent à un cercle C centré sur le point central de la paroi frontale 17 et passant par le trou 22. Les axes X2 de tous les trous 22 présentent une inclinaison de même sens par rapport à la normale X1 correspondante. Cette inclinaison peut avantageusement être la même pour tous les trous, et être comprise par exemple entre 10 et 60 deg. , notamment de l'ordre de 30°.In the variant shown on the figures 11 to 13 , in a complementary or independent manner to the production of the elastically deformable front wall 17, each hole 22 of the front wall 17 of the spray nozzle extends along an axis X2 inclined with respect to the normal X1 to said front wall at the level of said hole 22. The axis X2 and the normal X1 define a plane substantially tangent to a circle C centered on the central point of the front wall 17 and passing through the hole 22. The axes X2 of all the holes 22 have an inclination of the same direction compared to the corresponding normal X1. This inclination can advantageously be the same for all the holes, and be for example between 10 and 60 degrees. , in particular of the order of 30°.

Du fait que les trous 22 sont tous inclinés dans le même sens angulaire 24 (figure 6), lorsqu'un aérosol A est généré par la buse de pulvérisation (voir figure 8), la trajectoire v suivie par chaque gouttelette de liquide de l'aérosol est une trajectoire tourbillonnante autour de l'axe central X de la buse de pulvérisation.Because the holes 22 are all inclined in the same angular direction 24 ( figure 6 ), when an aerosol A is generated by the spray nozzle (see figure 8 ), the trajectory v followed by each liquid droplet of the aerosol is a swirling trajectory around the central axis X of the spray nozzle.

L'aérosol A présente une première partie b1, au voisinage de la buse de pulvérisation, dans laquelle les gouttelettes de liquide sont animées d'une grande vitesse d'avancement et qui est sensiblement conique ayant un angle d'ouverture relativement élevé, par exemple de l'ordre de 20 deg. ou plus.The aerosol A has a first part b1, in the vicinity of the spray nozzle, in which the droplets of liquid are driven at a high forward speed and which is substantially conical having a relatively high angle of opening, for example of the order of 20 deg. or more.

De plus, l'aérosol A présente une deuxième partie p2 formant un nuage dans lequel les gouttelettes de liquide ont une vitesse d'avancement moindre que dans la première partie p1. Grâce au mouvement tourbillonnaire des gouttelettes de liquide, la deuxième partie b2 de l'aérosol reste relativement symétrique par rapport à l'axe X.In addition, aerosol A has a second part p2 forming a cloud in which the liquid droplets have a slower forward speed than in the first part p1. Thanks to the swirling movement of the liquid droplets, the second part b2 of the aerosol remains relatively symmetrical with respect to the X axis.

Dans cette variante, avec une paroi frontale 17 comprenant une centaine de trous 22 de diamètre 3 m ménagés dans une paroi 17 d'épaisseur 0,3 mm, avec une inclinaison des trous de l'ordre de 30 deg. et avec une pression d'un liquide alcoolique de l'ordre de 0,5 bars à l'intérieur de la buse de pulvérisation, on obtient la pulvérisation d'un aérosol constitué de gouttelettes de diamètre 5 µm à 7 µm.In this variant, with a front wall 17 comprising a hundred holes 22 with a diameter of 3 m made in a wall 17 with a thickness of 0.3 mm, with an inclination of the holes of the order of 30 deg. and with a pressure of an alcoholic liquid of the order of 0.5 bars inside the spray nozzle, the spraying of an aerosol consisting of droplets with a diameter of 5 μm to 7 μm is obtained.

On peut prévoir, en variante, que la paroi frontale 17 soit déformable élastiquement. A l'état de repos, les trous calibrés 22 peuvent alors être réalisés de manière simple avec un axe X2 qui s'étend dans un plan parallèle à l'axe central X de la buse de pulvérisation 16. La divergence de l'axe X2 des trous calibrés 22 peut être obtenue lors de l'actionnement du poussoir pour augmenter l'angle d'ouverture de la première partie de l'aérosol A. Provision can be made, as a variant, for the front wall 17 to be elastically deformable. In the rest state, the calibrated holes 22 can then be made in a simple manner with an axis X2 which extends in a plane parallel to the central axis X of the spray nozzle 16. The divergence of the axis X2 calibrated holes 22 can be obtained when the pusher is actuated to increase the opening angle of the first part of the aerosol A.
