Description

Dispositif de pulvérisation de produit fluide Fluid spray device
La présente invention concerne un dispositif de pulvérisation de produit fluide, tel que du parfum, apte à produire un nuage de fines gouttelettes. The present invention relates to a device for spraying a fluid product, such as perfume, capable of producing a cloud of fine droplets.
Dans l’art antérieur, on connaît déjà les pompes et les valves qui permettent de créer une pulvérisation de produit fluide en appuyant sur un poussoir ou en écrasant un réservoir de produit fluide. In the prior art, pumps and valves are already known which make it possible to create a spray of fluid product by pressing a pusher or by crushing a reservoir of fluid product.
On connaît aussi le document FR2846306, qui décrit un distributeur de produit fluide comprenant un réservoir de produit fluide de volume variable, définissant une paroi déplaçable de manière à faire varier le volume du réservoir. Le distributeur comprend en outre un orifice de distribution en communication avec le réservoir, de sorte que le produit fluide du réservoir peut être refoulé, lors d’une diminution de volume du réservoir, à travers l’orifice de distribution. Ce distributeur comprend deux parois d’actionnement entre lesquelles le réservoir est disposé. Ces parois d’actionnement permettent, dans un premier temps, d’augmenter le volume du réservoir par entrée d’air dans le réservoir et, dans un second temps, de diminuer le volume du réservoir en refoulant de l’air et du produit fluide à travers l’orifice de distribution. Plus précisément, c’est la courbure différenciée des deux parois d’actionnement qui permet de faire ainsi varier le volume du réservoir. Document FR2846306 is also known, which describes a fluid dispenser comprising a fluid reservoir of variable volume, defining a movable wall so as to vary the volume of the reservoir. The dispenser further comprises a dispensing orifice in communication with the reservoir, so that the fluid from the reservoir can be discharged, when the volume of the reservoir decreases, through the dispensing orifice. This dispenser comprises two actuating walls between which the reservoir is arranged. These actuating walls make it possible, firstly, to increase the volume of the reservoir by air entering the reservoir and, secondly, to reduce the volume of the reservoir by discharging air and fluid. through the dispensing orifice. More precisely, it is the differentiated curvature of the two actuating walls which thus makes it possible to vary the volume of the reservoir.
Le but de la présente invention est de pouvoir réaliser une pulvérisation de produit fluide au moyen de la déformation (courbure pliage, cintrage, etc.) d’une seule paroi supportant le produit fluide, à la manière d’une peau d’orange qui génère des sprays d’essence lorsqu’on la plie. En effet, la peau d’orange comprend une couche appelée « épicarpe » qui contient des glandes à essence. L’épicarpe recouvre une couche profonde appelée « mésocarpe ». Lorsque l’on plie la peau d’orange, les glandes à essence sont mises sous pression et l’épicarpe va se fendre, permettant ainsi à l’essence de s’échapper à travers les fentes de l’épicarpe, qui font office d’orifice de pulvérisation. L’essence est alors distribuée sous forme de fine gouttelettes. Un but de l’invention est de recréer artificiellement la structure de la peau d’orange et plus particulièrement sa capacité à créer des sprays lorsqu’elle est pliée. The aim of the present invention is to be able to spray a fluid product by means of the deformation (bending, bending, bending, etc.) of a single wall supporting the fluid, in the manner of an orange peel which generates gasoline sprays when folded. Indeed, the orange peel includes a layer called "epicarp" which contains gasoline glands. The epicarp covers a deep layer called the “mesocarp”. When the orange peel is folded, the gasoline glands are put under pressure and the epicarp will split, allowing the essence to escape through the slits in the epicarp, which act as a spray orifice. The gasoline is then distributed in the form of fine droplets. A goal of the invention is to artificially recreate the structure of the orange peel and more particularly its ability to create sprays when it is folded.
Pour ce faire, la présente invention propose un dispositif de pulvérisation de produit fluide comprenant : To do this, the present invention proposes a device for spraying a fluid product comprising:
- un substrat pliable définissant deux bords opposés et une zone de pliage disposées entre les deux bords opposés, les deux bords opposés étant aptes à se rapprocher l’un de l’autre par pliage de la zone de pliage, - a foldable substrate defining two opposite edges and a folding zone arranged between the two opposite edges, the two opposite edges being able to move closer to each other by folding the folding zone,
- une couche porteuse appliquée sur la zone de pliage, - a carrier layer applied to the folding area,
- un produit fluide contenu dans la couche porteuse, de telle sorte que le pliage du substrat pliable entraine une augmentation de la pression du produit fluide contenu dans la couche porteuse, ce qui a pour conséquence d’expulser le produit fluide hors de la couche porteuse sous forme de petits sprays de fines gouttelettes pulvérisées. a fluid product contained in the carrier layer, such that the folding of the pliable substrate causes an increase in the pressure of the fluid product contained in the carrier layer, which has the consequence of expelling the fluid product out of the carrier layer in the form of small sprays of fine spray droplets.
L’analogie avec la structure de la peau d’orange peut être faite : le substrat pliable correspond au mésocarpe et la couche porteuse renfermant le produit fluide correspond à l’épicarpe. Le pliage de l’ensemble génère des petits sprays de produit fluide à travers un pluralité d’orifices de pulvérisation. The analogy with the structure of the orange peel can be made: the pliable substrate corresponds to the mesocarp and the carrier layer containing the fluid corresponds to the epicarp. Folding the assembly generates small sprays of fluid through a plurality of spray ports.
Selon une caractéristique avantageuse de l’invention, le dispositif de pulvérisation peut en outre comprendre une paroi de pulvérisation qui est disposée sur la couche porteuse, la paroi de pulvérisation formant des orifices de pulvérisation. Selon une réalisation possible, les orifices de pulvérisation sont créés au moment du pliage du substrat pliable, avantageusement à partir d’amorces de rupture. According to an advantageous characteristic of the invention, the spray device can further comprise a spray wall which is disposed on the carrier layer, the spray wall forming spray orifices. According to one possible embodiment, the spray orifices are created when the bendable substrate is folded, advantageously from fracture initiators.
Selon une autre caractéristique avantageuse de l’invention, le dispositif de pulvérisation peut en outre comprendre un film disposé sur la couche porteuse ou sur la paroi de pulvérisation, ce film étant retiré avant pliage du substrat pliable. On peut également qualifier ce film d’opercule pelable. C’est à l’utilisateur de le retirer avant de plier le substrat. According to another advantageous characteristic of the invention, the spraying device may further comprise a film disposed on the carrier layer or on the spraying wall, this film being removed before folding the foldable substrate. We can also call this film a peelable seal. It is up to the user to remove it before folding the substrate.
Selon un mode de réalisation avantageux, le produit fluide est conditionné dans des microcapsules éclatables qui sont noyées dans la couche porteuse. Les microcapsules peuvent être intégrées à la couche porteuse avant de déposer la couche porteuse sur le substrat pliable. En variante, les microcapsules peuvent être intégrées à couche porteuse, alors que cette dernière est déjà déposée sur le substrat pliable. La couche porteuse peut être souple de manière à permettre son pliage, mais peut présenter une résistance à l’écrasement. Elle peut être réalisée à partir d’un thermoplastique, avantageusement élastomère. Avantageusement, la couche porteuse définit une surface externe, les microcapsules éclatables affleurant la surface externe. Ainsi, la couche porteuse présente une épaisseur réduite, voire nulle, aux endroits où les microcapsules affleurent. Cela permet de définir des zones de moindre résistance qui vont facilement rompre, créant ainsi des orifices de pulvérisation. En variante, on peut toutefois imaginer que les microcapsules soient profondément noyées dans la couche porteuse, qui devra alors présenter des propriétés telles qu’elle puisse de fendre facilement par pliage pour créer des orifices de pulvérisation. Quoi qu’il en soit, la couche porteuse est déformable et contribue à l’éclatement des microcapsules éclatables. According to an advantageous embodiment, the fluid product is packaged in burstable microcapsules which are embedded in the carrier layer. The microcapsules can be integrated with the carrier layer before depositing the carrier layer on the pliable substrate. In As a variant, the microcapsules can be integrated with a carrier layer, while the latter is already deposited on the foldable substrate. The carrier layer may be flexible so as to allow it to be folded, but may exhibit resistance to crushing. It can be made from a thermoplastic, advantageously an elastomer. Advantageously, the carrier layer defines an external surface, the burstable microcapsules flush with the external surface. Thus, the carrier layer has a reduced thickness, or even zero, at the places where the microcapsules are flush. This helps define areas of least resistance that will easily rupture, creating spray holes. As a variant, however, one can imagine that the microcapsules are deeply embedded in the carrier layer, which must then have properties such that it can easily split by bending to create spray orifices. In any event, the carrier layer is deformable and contributes to the bursting of the burstable microcapsules.
Selon un autre mode de réalisation avantageux, la couche porteuse peut être poreuse et écrasable et imprégnée de produit fluide. Elle peut alors se présenter sous la forme d’une mousse ou d’une éponge. According to another advantageous embodiment, the carrier layer can be porous and crushable and impregnated with fluid. It can then be in the form of a foam or a sponge.
Selon encore un autre mode de réalisation avantageux, la couche porteuse forme des cuvettes remplies de produit fluide et scellées par la paroi de pulvérisation. Elle peut alors se présenter sous la forme d’une mousse à cellules fermées, dont la face supérieure définit des cavités, dépressions, reliefs, cuvettes, etc. permettant de recueillir du produit fluide. According to yet another advantageous embodiment, the carrier layer forms cuvettes filled with fluid and sealed by the spray wall. It can then be in the form of a closed cell foam, the upper face of which defines cavities, depressions, reliefs, basins, etc. making it possible to collect fluid.
Selon un aspect intéressant de l’invention, le substrat pliable peut présenter une légère courbure à l’état de repos, afin d’induire le sens du pliage. According to an interesting aspect of the invention, the foldable substrate can have a slight curvature in the rest state, in order to induce the direction of the fold.
Le film peut par exemple contraindre le substrat pliable dans un état plan, de sorte qu’après retrait du film, le substrat pliable revient dans état de repos légèrement courbé. On peut aussi envisager que la face inférieure du substrat pliable soit courbée ou concave. The film may for example constrain the foldable substrate into a planar state, so that after removal of the film, the foldable substrate returns to a slightly curved rest state. It is also conceivable that the underside of the foldable substrate is curved or concave.
En variante, le substrat pliable peut présenter au moins une amorce de pliage, afin d’induire le sens du pliage. Cette amorce de pliage peut être prévu au niveau de la face inférieure du substrat pliable, par exemple sous la forme d’une rainure. Par ailleurs, le substrat pliable peut être réalisé à base de matériaux cellulosiques compatibles avec le parfum. As a variant, the bendable substrate can have at least one folding initiator, in order to induce the direction of the folding. This folding initiator can be provided at the level of the lower face of the foldable substrate, for example in the form of a groove. Furthermore, the pliable substrate can be made from cellulosic materials compatible with the perfume.
L’esprit de l’invention réside dans le fait de reproduire la structure et la dynamique de la peau d’orange avec des moyens industriels, notamment en terme de matériaux, procédés et assemblage, dans le but de produire un réseau régulier ou aléatoire d’orifices de pulvérisation à travers lesquels le produit fluide est distribué sous la forme de petits sprays. The spirit of the invention lies in the fact of reproducing the structure and dynamics of the orange peel with industrial means, in particular in terms of materials, processes and assembly, with the aim of producing a regular or random network of 'Spray orifices through which the fluid is distributed in the form of small sprays.

On se référera tout d’abord aux figures 1a et 1b pour décrire en détail la structure du dispositif de pulvérisation selon un premier mode de réalisation de l’invention. Il comprend trois éléments constitutifs essentiels, à savoir un substrat S1 , des microcapsules M remplies de produit fluide P et une couche porteuse C1. Optionnellement, le dispositif de pulvérisation comprend également un film F qui recouvre les microcapsules M et la couche porteuse C1. Reference will firstly be made to FIGS. 1a and 1b in order to describe in detail the structure of the spraying device according to a first embodiment of the invention. It includes three essential building blocks, namely a substrate S1, microcapsules M filled with fluid P and a carrier layer C1. Optionally, the spray device also comprises a film F which covers the microcapsules M and the carrier layer C1.
Le substrat S1 se présente sous la forme d’une plaque d’épaisseur sensiblement constante. La forme de cette plaque n’est pas critique pour l’invention. Toutefois, le substrat S1 comprend deux bords opposés B ainsi qu’une zone de pliage Zp qui est située entre les deux bords opposés B. Avantageusement, la zone de pliage Zp est située à mi-distance entre les deux bords opposés B. Selon l’invention, le substrat S1 est pliable au niveau de la zone de pliage Zp, comme on le verra ci-après. Afin de favoriser le pliage, la zone de pliage Zp peut être pourvue d’une amorce de pliage Sp, visible sur la figure 1b. Cette amorce de pliage Sp impose la localisation du pliage ainsi que le sens du pliage. Le substrat pliable S1 peut être réalisé à partir de n’importe quel matériau approprié, comme par exemple un matériau cellulosique. Sa face inférieure peut servir de support de communication. The S1 substrate is in the form of a plate of substantially constant thickness. The shape of this plate is not critical to the invention. However, the substrate S1 comprises two opposite edges B as well as a folding zone Zp which is located between the two opposite edges B. Advantageously, the folding zone Zp is located midway between the two opposite edges B. According to l 'invention, the substrate S1 is foldable at the level of the folding zone Zp, as will be seen below. In order to promote folding, the folding zone Zp can be provided with a folding initiator Sp, visible in FIG. 1b. This initiation of folding Sp imposes the location of the folding as well as the direction of the folding. The S1 foldable substrate can be made from any suitable material, such as cellulosic material. Its underside can serve as a communication medium.
Les microcapsules M se présentent sous la forme de petites sphères contenant du produit fluide P. Les microcapsules M sont écrasables de manière à pouvoir en extraire le produit fluide P. Le diamètre des microcapsules peut varier de quelques pm à 100 pm. The microcapsules M are in the form of small spheres containing the fluid product P. The microcapsules M are crushable so as to be able to extract the fluid product P. The diameter of the microcapsules can vary from a few μm to 100 μm.
Le produit fluide P contenu dans les microcapsules M peut être de toute nature, comme par exemple du parfum, une lotion, un sérum, etc. Le produit fluide P peut être alcoolique ou aqueux. The fluid product P contained in the microcapsules M can be of any kind, such as, for example, perfume, a lotion, a serum, etc. The fluid product P can be alcoholic or aqueous.
La couche porteuse C1 sert tout d’abord de liant pour les microcapsules M, de manière à pouvoir les maintenir sur une face du substrat pliable S1. Cette couche porteuse C1 peut être réalisée avec n’importe quel matériau approprié, comme par exemple un matériau plastique. La couche porteuse C1 peut être sensiblement rigide, mais toutefois pliable, ou encore relativement souple ou molle de manière à pouvoir être écrasée dans son épaisseur. Les microcapsules M sont noyées dans la couche porteuse C1 . Avantageusement, la couche porteuse C1 définit une surface externe C11 , visible sur la figure 2b, et les microcapsules M viennent en affleurement avec cette surface externe C11 . En variante, les microcapsules M peuvent être complètement noyées à l’intérieur de la couche porteuse C1. Les microcapsules M peuvent venir en contact avec le substrat pliable S1 , ou au contraire en être séparées par la couche porteuse C1 . La couche porteuse C1 et ses microcapsules noyées M recouvrent sensiblement la totalité de la zone de pliage Zp. Les microcapsules M sont de préférence disposées à plat sur le substrat pliable S1 en formant une couche unique. Les microcapsules M peuvent être disposées de manière jointive, ou au contraire être espacées les unes des autres par la couche porteuse C1 . The carrier layer C1 serves first of all as a binder for the microcapsules M, so as to be able to hold them on one side of the foldable substrate S1. This carrier layer C1 can be made with any suitable material, such as for example a plastic material. The carrier layer C1 can be substantially rigid, but nevertheless pliable, or else relatively flexible or soft so as to be able to be crushed in its thickness. The microcapsules M are embedded in the carrier layer C1. Advantageously, the carrier layer C1 defines an external surface C11, visible in FIG. 2b, and the microcapsules M come flush with this external surface C11. As a variant, the microcapsules M can be completely embedded inside the carrier layer C1. The microcapsules M can come into contact with the foldable substrate S1, or on the contrary be separated therefrom by the carrier layer C1. The carrier layer C1 and its embedded microcapsules M substantially cover the whole of the folding zone Zp. The microcapsules M are preferably placed flat on the foldable substrate S1, forming a single layer. The microcapsules M can be arranged contiguously, or on the contrary be spaced from one another by the carrier layer C1.
A la place des microcapsules M, on peut aussi prévoir une couche porteuse poreuse, telle qu’une mousse à cellules ouvertes, dans laquelle le produit fluide est imbibé. Instead of the microcapsules M, it is also possible to provide a porous carrier layer, such as an open-cell foam, in which the fluid product is soaked.
Le film F recouvre la couche porteuse C1 et ses microcapsules noyées M de manière à entourer la zone de pliage Zp. La périphérie extérieure du film F peut être scellée au substrat pliable S1. Le film F peut comprendre une languette de préhension F1 par laquelle un utilisateur peut saisir le film F pour le retirer du substrat pliable S1 et de la couche porteuse C1 , de manière à la découvrir. L’utilisateur peut ensuite saisir le substrat pliable S1 par ses deux bords opposés B et exercer une pression de manière à les rapprocher, ce qui génère un pliage au niveau de la zone de pliage Zp, initié par l’amorce de pliage Sp, comme visible sur la figure 2a. Le pliage de la zone Zp génère des contraintes dans le substrat pliable S1 , ces contraintes s’exerçant ensuite sur la couche porteuse C1 et ses microcapsules M. Les microcapsules M vont ainsi être mises sous pression ou tension jusqu’à ce qu’elles éclatent au niveau de la surface externe C11 de la couche porteuse C1 , comme on peut le voir sur la figure 2b. Le produit fluide P mis sous pression dans les microcapsules trouve ainsi des passages ou orifices de sortie à travers lesquels le produit fluide est pulvérisé sous forme de fines gouttelettes. En d’autres termes, chaque microcapsule M est contrainte jusqu’à ce qu’elle éclate en formant un passage de sortie pour le produit fluide sous pression. Etant donné que les microcapsules M viennent avantageusement en affleurement de la surface externe C11 de la couche porteuse C1 , le passage de sortie est ainsi imposé au niveau où la microcapsule M n’est pas complètement entourée par la couche porteuse C1 . The film F covers the carrier layer C1 and its embedded microcapsules M so as to surround the folding zone Zp. The outer periphery of the film F can be sealed to the foldable substrate S1. The film F can include a gripping tab F1 by which a user can grip the film F to remove it from the foldable substrate S1 and from the carrier layer C1, so as to uncover it. The user can then grip the bendable substrate S1 by its two opposite edges B and exert pressure so as to bring them together, which generates a folding at the level of the folding zone Zp, initiated by the folding initiator Sp, as visible in figure 2a. The folding of the zone Zp generates stresses in the foldable substrate S1, these stresses then being exerted on the carrier layer C1 and its microcapsules M. The microcapsules M will thus be put under pressure or tension until they burst. at the level of the external surface C11 of the carrier layer C1, as can be seen in FIG. 2b. The fluid product P pressurized in the microcapsules thus finds passages or outlet openings through which the fluid product is sprayed in the form of fine droplets. In other words, each microcapsule M is strained until it bursts forming an outlet passage for the pressurized fluid product. Given that the microcapsules M advantageously come flush with the external surface C11 of the carrier layer C1, the passage output is thus imposed at the level where the microcapsule M is not completely surrounded by the carrier layer C1.
L’angle de pliage de la zone Zp peut aller de l’ordre de 60° à 180°. Les deux bords opposés B peuvent même venir en contact l’un de l’autre. The bending angle of the Zp zone can range from 60 ° to 180 °. The two opposite edges B may even come into contact with each other.
Avantageusement, l’éclatement des microcapsules M résulte des contraintes exercées par le substrat pliable S1 sur la couche porteuse C1 , qui ensuite exerce une contrainte sur les microcapsules M. La contrainte exercée par la couche porteuse C1 peut être une contrainte d’écrasement, ou au contraire une contrainte d’étirement. La contrainte exercée par la zone de pliage Zp peut également s’exercer directement sur les microcapsules M, de sorte que leur éclatement résulte de la combinaison des contraintes exercées par la zone Zp et la couche porteuse C1 . La contrainte exercée par la couche porteuse C1 peut également être une contrainte d’écrasement dans le sens de l’épaisseur de la couche porteuse C1 . Le pliage conduit à une rupture de la couche porteuse et/ou des microcapsules M qui forment des orifices de pulvérisation pour le produit fluide contenu dans les microcapsules, qui en est ainsi expulsé sous la forme de petits sprays de fines gouttelettes. Advantageously, the bursting of the microcapsules M results from the stresses exerted by the foldable substrate S1 on the carrier layer C1, which then exerts a stress on the microcapsules M. The stress exerted by the carrier layer C1 can be a crushing stress, or on the contrary, a stretch constraint. The stress exerted by the folding zone Zp can also be exerted directly on the microcapsules M, so that their bursting results from the combination of the stresses exerted by the zone Zp and the carrier layer C1. The stress exerted by the carrier layer C1 can also be a crushing stress in the direction of the thickness of the carrier layer C1. Folding leads to rupture of the carrier layer and / or of the microcapsules M which form spray orifices for the fluid product contained in the microcapsules, which is thus expelled therefrom in the form of small sprays of fine droplets.
La figure 3 illustre une variante de réalisation dans laquelle le substrat pliable S2 présente une face inférieure Sc qui est concave, mais peut toutefois servir de support de communication. Du fait de cette concavité, l’épaisseur de paroi du substrat pliable S2 est plus faible au niveau de sa zone de pliage Zp qu’au niveau de ses bords opposés B. Ainsi, la localisation et le sens du pliage est imposé au niveau où le substrat pliable S2 présente son épaisseur minimum. Dans ce second mode de réalisation, le film pelable F a été remplacé par une paroi de pulvérisation W1 qui recouvre la couche porteuse C1 et ses microcapsules M remplies de produit fluide P. Contrairement au film pelable F, la paroi de pulvérisation W1 est montée à demeure et n’a pas vocation à être retirée pour pouvoir utiliser le dispositif de pulvérisation. La paroi de pulvérisation W1 peut par exemple être formée avec des amorces de rupture W11 , qui sont visibles sur la figure 5a. Ainsi, à l’état initial de repos comme représenté sur la figure 3, la paroi de pulvérisation W1 est intacte et ne présente aucun trou. A l’usage, le pliage du substrat S2 va générer une contrainte d’étirement sur la paroi de pulvérisation W1 qui va ainsi rompre au niveau des amorces de rupture W11 . En variante, il est également possible que la paroi W1 ne comprenne pas d’amorce de rupture et se fende lors du pliage de manière aléatoire ou régulière. La paroi de pulvérisation W1 peut par exemple présenter une épaisseur variable de sorte que des ouvertures de pulvérisation se forment au niveau où elles présentent la moindre épaisseur. FIG. 3 illustrates an alternative embodiment in which the foldable substrate S2 has a lower face Sc which is concave, but can nevertheless serve as a communication medium. Due to this concavity, the wall thickness of the foldable substrate S2 is lower at its folding zone Zp than at its opposite edges B. Thus, the location and direction of the folding is imposed at the level where the foldable substrate S2 has its minimum thickness. In this second embodiment, the peelable film F has been replaced by a spray wall W1 which covers the carrier layer C1 and its microcapsules M filled with fluid P. Unlike the peelable film F, the spray wall W1 is mounted at remains and is not intended to be removed in order to use the spray device. The spray wall W1 can for example be formed with rupture initiators W11, which are visible in FIG. 5a. Thus, in the initial state of rest as shown in Figure 3, the spray wall W1 is intact and has no holes. In use, the folding of the substrate S2 will generate a stretching stress on the spray wall W1 which will thus break at the level of the fracture initiators W11. As a variant, it is also possible that the wall W1 does not include the initiation of a rupture and splits during folding in a random or regular manner. The spray wall W1 can for example have a variable thickness so that spray openings are formed at the level where they have the least thickness.
Le dispositif de pulvérisation de la figure 4 peut comprendre un substrat pliable S1 , qui est avantageusement compatible avec l’alcool. Il peut par exemple être réalisé à base d’un matériau cellulosique. En revanche, ce dispositif de pulvérisation ne comprend pas de microcapsules M, mais une couche porteuse C2 qui est poreuse, écrasable et imprégnée de produit fluide. La couche porteuse C2 peut par exemple se présenter sous la forme d’une mousse écrasable à pores ouverts. La couche porteuse C2 peut être entièrement ou partiellement remplie de produit fluide. On peut par exemple envisager que les cavités de la couche porteuse soient à moitié remplies par des produits fluides et de l’air, de manière à produire un spray biphasique. La couche porteuse C2 est recouverte par une paroi de pulvérisation W2 qui peut être formée avec des orifices de pulvérisation W21 , comme on peut le voir sur la figure 5b. En variante, il est également possible de remplacer la paroi de pulvérisation W2 par la paroi de pulvérisation W1 des figures 3 et 5a. On peut également envisager que la paroi de pulvérisation ne comprenne ni d’orifice de pulvérisation, ni d’amorce de rupture et se fende au moment du pliage. La paroi de pulvérisation W2 est ici recouverte avec un film pelable F, similaire ou identique à celui du premier mode de réalisation. The spray device of Figure 4 may include a collapsible substrate S1, which is advantageously compatible with alcohol. It can for example be made from a cellulosic material. On the other hand, this spraying device does not include microcapsules M, but a carrier layer C2 which is porous, crushable and impregnated with fluid. The carrier layer C2 can, for example, be in the form of a crushable foam with open pores. The carrier layer C2 can be entirely or partially filled with fluid. For example, it is conceivable that the cavities of the carrier layer are half filled with fluid products and air, so as to produce a two-phase spray. The carrier layer C2 is covered by a spray wall W2 which can be formed with spray ports W21, as can be seen in Fig. 5b. As a variant, it is also possible to replace the spray wall W2 with the spray wall W1 of Figures 3 and 5a. It is also conceivable that the spray wall does not include a spray orifice or a break initiator and splits when folding. The spray wall W2 is here covered with a peelable film F, similar or identical to that of the first embodiment.
La paroi de pulvérisation W2 peut par exemple comprendre de 10 à 500 orifices de pulvérisation présentant un diamètre allant de 5 pm à 100 pm. Il est également envisageable de prévoir des trous des orifices de pulvérisation de taille différente sur une même paroi de pulvérisation W2. The spray wall W2 may for example comprise from 10 to 500 spray orifices having a diameter ranging from 5 μm to 100 μm. It is also possible to envisage providing holes for the spray orifices of different size on the same spray wall W2.
Dans le quatrième mode de réalisation des figures 6a et 6b, le substrat pliable S3 est laminé et comprend deux couches S31 et S32. La couche supérieure S31 peut par exemple être réalisée avec un film à base d’un matériau cellulosique compatible avec l’alcool. Quant à la couche inférieure S32, elle peut être réalisée à partir d’une plaque de carton de cellulose et peut définir une amorce de pliage Sp. La face inférieure de la couche inférieure S32 peut servir de support de communication. La couche porteuse C3 se présente ici sous la forme d’une galette souple formant des petites cuvettes C31 . La couche porteuse C3 peut par exemple être réalisée à partir d’une mousse à cellule fermée ou d’un élastomère. Les petites cuvettes C31 sont partiellement ou totalement remplies de produit fluide P, comme on peut le voir sur la figure 6b. Les cuvettes C31 contenant le produit fluide P sont ensuite scellées à l’aide d’une paroi de pulvérisation W1 , qui peut être identique ou similaire à celle des figures 3 et 5a. En utilisation, le substrat S3 est plié de manière à déformer la couche porteuse C3 et à faire rompre les amorces de rupture de la paroi de pulvérisation W1 . Le produit fluide P mis sous pression dans les cuvettes C31 est ainsi refoulé à travers la paroi de pulvérisation W1 sous la forme d’un spray constitué de fines gouttelettes. A la place de la paroi de pulvérisation W1 , on peut également utiliser la paroi de pulvérisation W2 en association avec un film pelable F. In the fourth embodiment of Figures 6a and 6b, the foldable substrate S3 is laminated and comprises two layers S31 and S32. The upper layer S31 can for example be produced with a film based on a cellulosic material compatible with alcohol. As for the lower layer S32, it can be made from a sheet of cellulose cardboard and can define a folding initiator Sp. The underside of the lower layer S32 can serve as a communication medium. The carrier layer C3 is here in the form of a flexible wafer forming small cuvettes C31. The carrier layer C3 can for example be produced from a closed cell foam or from an elastomer. The small bowls C31 are partially or totally filled with fluid P, as can be seen in FIG. 6b. The cuvettes C31 containing the fluid product P are then sealed using a spray wall W1, which may be identical or similar to that of FIGS. 3 and 5a. In use, the substrate S3 is folded so as to deform the carrier layer C3 and to break the fracture initiators of the spray wall W1. The fluid product P put under pressure in the cuvettes C31 is thus discharged through the spray wall W1 in the form of a spray consisting of fine droplets. Instead of the spray wall W1, it is also possible to use the spray wall W2 in combination with a peelable film F.
Quel que soit le mode de réalisation, le produit fluide P est supporté par ou contenu dans une couche porteuse qui est mise sous contrainte à l’aide d’un substrat pliable. Le produit fluide P est ainsi mis sous pression dans la couche porteuse jusqu’à ce qu’il trouve des passages de sortie à travers lesquels il est pulvérisé en fines gouttelettes. Les passages de sortie pour le produit fluide peuvent être créés par l’éclatement de microcapsules ou la mise en œuvre d’une paroi de pulvérisation pré-percée ou qui va se rompre sous l’action combinée de la pression du produit fluide et des contraintes exercées sur elle. Regardless of the embodiment, the fluid product P is supported by or contained in a carrier layer which is stressed using a pliable substrate. The fluid P is thus pressurized in the carrier layer until it finds outlet passages through which it is sprayed in fine droplets. The outlet passages for the fluid product can be created by the bursting of microcapsules or the implementation of a pre-pierced spray wall or which will rupture under the combined action of the pressure of the fluid product and the stresses. exerted on it.
