- the dispensing member 34 is for example formed by a pump 80 capable of causing aspiration of the heterogeneous medium 14 into the delivery element 32, then passing this medium 14 through the filtration member 44 to form the composition 12, and finally to convey the composition 12 to a dispensing orifice 82 located on the member 34 towards the outside of the device 10.

- the particles 20 when the particles 20 are rigid, they block against the wall 56 in the intermediate space delimited between the perforated wall 56 and the body 46 of the duct 42. Only the homogeneous medium 18 liquid passes through the openings 58 of filtration. The homogeneous medium 18 thus forms the fluid composition 12 which rises through the downstream opening 54, the distribution channel 84. This composition is extracted through the dispensing orifice 82 out of the device 10, for example in the form of a jet or a spray.
- the particles 20 disintegrate in contact with the perforated wall 56. Their contents pass through the openings 58 and form, by mixing with the medium 18, the fluid composition 12. The solid residue resulting from the disintegration of the particles 20 is blocked by the perforated wall 56.

- the upstream restriction 1 12 furthermore includes an internal radial projection 116 intended to break up the particles 20 in order to homogenize the heterogeneous medium 14.
- the internal radial projection 1 16 is preferably annular. It projects from the wall of the conduit 42 defining the restriction 1 12. It defines a central lumen 1 18 through which the medium 14 passes, with a transverse extension smaller than the average diameter of the particles 20 (see FIG. 6).
- the height of the restriction 1 12 is less than the height of the downstream section 1 14, taken along the axis A-A '. This height is advantageously less than 50% of the height of the downstream section 1 14, especially less than 20% of the height of the downstream section 1 14.
- the downstream section 1 14 receives the filter member 44.
- the free end 62 of the perforated wall 56 is located at an axial distance from the restriction 1 12 along the axis A-A '.
- the minimum transverse extent of the downstream section 1 14 is greater than 1.5, in particular greater than 2.5 times the average diameter of the particles 20. It is thus greater than 200%, in particular 300% of the minimum transverse extent of the restriction. 1 12.
- downstream section 1 14 has a substantially constant inner cross section.
- the operation of the second device according to the invention 1 10 differs from the operation of the first device 10 according to the invention in that the passage of the particles 20 in the restriction 1 12 aligns the particles 20 to advantageously place them in single file, which facilitates their aspiration. Then, the projection 1 16 present in the restriction 1 12 produces their disintegration.
- the envelope 24 of the particles 20 breaks in the restriction 1 12 to the passage of the projection 1 16, releasing the heart 22.
- the core 22 thus mixes with the medium 18 to form the fluid composition 12 which passes through the filtration member 44.
- the envelope 24 forms a semi-solid residue 120 which is retained by the filtration wall 56 without passing through the openings 58.
- the delivery element 32 is therefore effective both for forming the fluid composition 12 by releasing the core 22 in the restriction 1 12 and for very effectively retaining the remaining residue 120 of the envelope 24.
- the residue 120 of the envelopes 24 is held little by little in the upper part of the filtering member 44. It thus accumulates without completely clogging the filtering member 44, until all the contents of the dispensing device 1 10 is used.
- the particles 20 disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and at least a portion of the particles 20 disintegrate in contact with the filter member 44.
- the particles 20 partially disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and end to disintegrate in contact with the filter member 44.
- a fluid composition 14 homogeneous, without any debris is thus delivered through the dispensing orifice 82, without producing debris unfavorable to the feel of use to the touch of the composition delivered, for example on the skin of a user, or produce debris that can block the dispenser member
- the volume of the upstream portion of the central passage 50 situated upstream of the filtration member 44 in the central passage 50 is greater, and is in particular greater than 1.5 times the maximum volume of the residues 120 intended to be recovered during of the disintegration of the particles in suspension.
- the maximum volume of the residues 120 is for example estimated by the sum of all the volumes of the envelopes 24 of the particles 20 contained in the heterogeneous mixture 14, received within the container 30.
- the free volume in the skin filter thus makes it possible to store all the semi-solid residues resulting from the disintegration and filtration of the heterogeneous starting mixture.
- the term “disaggregate” preferably means that the particles are torn, exploded, opened, and / or broken, thereby losing their integrity and releasing where appropriate their contents, as opposed to breaking a clump. of particles to obtain free particles maintaining their integrity.
- the volume delimited by the central passage and the filtering member 56 is greater than 1.5 the maximum volume occupied by all the residues 120 contained in the container 30.
- each filter opening 58 is smaller than the minimum area of each residue 120.
- the filtration openings 58 are advantageously of elongate shape, with the smallest dimension, here the width, less than a quarter of the diameter of the particles 20.
- the openings have a large surface, which allows a good return of the product to be delivered, but are also thin enough to prevent residues 120 to pass through the filter, even if they fold on themselves.
- the total area of the filtration openings 58 is greater than 0.2% and especially less than 10% of the total surface of the residues 120 contained in the container 30.
- the term "surface” applied to a residue 120 means the maximum surface area of all the surfaces measured over all the projections of this residue 120 on a plane, advantageously on the filter wall 56 of the filtering member 44.
- the free end 62 of the perforated filter wall 56 is axially spaced from the upstream opening 52.

Description
Élément de délivrance d'une composition fluide, dispositif de distribution et procédé associés Fluid composition delivery member, dispensing device and method thereof
La présente invention concerne un élément de délivrance d'une composition fluide, destiné à être monté dans un récipient contenant un mélange hétérogène, comprenant : The present invention relates to a fluid composition delivery member for mounting in a container containing a heterogeneous mixture comprising:
- un conduit de guidage de fluide, comprenant une ouverture amont destinée à s'ouvrir dans le récipient, un passage central, et une ouverture aval destinée à être raccordée à un organe de distribution de la composition fluide hors du récipient, le conduit de guidage définissant un axe de circulation de fluide à travers le passage central entre l'ouverture amont et l'ouverture aval ; a fluid guide duct, comprising an upstream opening intended to open into the container, a central passage, and a downstream opening intended to be connected to a dispensing member of the fluid composition out of the container, the guide duct; defining a fluid flow axis through the central passage between the upstream opening and the downstream opening;
- un organe de filtration, monté dans le conduit de guidage, l'organe de filtration étant configuré pour que le mélange hétérogène introduit dans le conduit de guidage à travers l'ouverture amont passe par l'organe de filtration. - A filter member mounted in the guide duct, the filter member being configured so that the heterogeneous mixture introduced into the guide duct through the upstream opening passes through the filter member.
Un tel élément est destiné à former une composition fluide, propre par exemple à être pompée à travers un organe de distribution de produit, à partir d'un mélange hétérogène formant une composition de départ. Such an element is intended to form a fluid composition, for example clean to be pumped through a product dispensing member, from a heterogeneous mixture forming a starting composition.
Le mélange hétérogène contient des éléments dispersés en suspension, tels que des particules solides, ou des billes, par exemple formées d'un cœur liquide ou gélifié, entouré par une écorce gélifiée. The heterogeneous mixture contains suspended dispersed elements, such as solid particles, or beads, for example formed of a liquid or gelled heart, surrounded by a gelled bark.
La composition fluide obtenue à partir du mélange hétérogène est avantageusement destinée à être utilisée dans le domaine cosmétique, alimentaire et/ou pharmaceutique. The fluid composition obtained from the heterogeneous mixture is advantageously intended to be used in the cosmetics, food and / or pharmaceutical field.
Pour délivrer une composition fluide à partir d'un mélange hétérogène ou complexe, tel qu'une solution visqueuse, hétérogène ou multiphasique, il est connu de développer des pompes particulières présentant des capacités d'aspiration élevées ou d'utiliser des systèmes sans air (ou « airless »). In order to deliver a fluid composition from a heterogeneous or complex mixture, such as a viscous, heterogeneous or multiphasic solution, it is known to develop particular pumps with high suction capacities or to use systems without air ( or "airless").
En effet, les pompes classiquement utilisées dans les dispositifs de distribution pour des compositions fluides sont inadaptées à l'aspiration de solutions contenant des solides en suspension. Par exemple, les solides en suspension sont susceptibles de bloquer la pompe ou de l'endommager au passage du piston, rendant le dispositif de distribution inutilisable pour l'utilisateur. Indeed, the pumps conventionally used in dispensing devices for fluid compositions are unsuitable for the suction of solutions containing suspended solids. For example, suspended solids may block the pump or damage it to the passage of the piston, rendering the dispensing device unusable for the user.
Les pompes spécifiquement développées pour la délivrance de milieux hétérogènes présentent de nombreux inconvénients. En particulier, ces pompes sont très spécifiques à une application donnée et présentent un domaine d'utilisations très réduit. Ce type de pompe est donc très onéreux. Pumps specifically developed for the delivery of heterogeneous media have many disadvantages. In particular, these pumps are very specific to a given application and have a very limited range of uses. This type of pump is very expensive.
US 5,284,275 décrit un élément de délivrance d'une composition adhésive formée à partir de billes d'un premier produit dispersées dans un deuxième produit. L'élément
comprend un conduit de guidage et une paroi de filtration perpendiculaire à l'axe de circulation du produit. Un piston pousse les billes vers la paroi de filtration, ce qui provoque leur rupture. No. 5,284,275 discloses a delivery member of an adhesive composition formed from beads of a first product dispersed in a second product. The element comprises a guide duct and a filtration wall perpendicular to the axis of circulation of the product. A piston pushes the balls towards the filtering wall, causing them to rupture.
Un tel élément ne donne pas entière satisfaction. En effet, la rupture des billes sur la paroi transversale entraîne rapidement un risque de bouchage de la paroi de filtration. L'élément décrit dans US 5,284,275 est donc adapté à un usage unique, et non à un dispositif de distribution prévu pour de multiples usages, comme par exemple dans le domaine cosmétique. Such an element does not give complete satisfaction. Indeed, the breaking of the balls on the transverse wall quickly leads to a risk of clogging of the filter wall. The element described in US 5,284,275 is therefore suitable for a single use, and not a distribution device provided for multiple uses, such as in the cosmetics field.
Un but de l'invention est donc de fournir un élément de délivrance d'une composition fluide obtenue à partir d'un milieu hétérogène, qui soit peu coûteux, tout en étant adapté à de multiples usages, dans les domaines cosmétique, pharmaceutique ou agroalimentaire. An object of the invention is therefore to provide a delivery element of a fluid composition obtained from a heterogeneous medium, which is inexpensive, while being adapted to multiple uses, in the cosmetic, pharmaceutical or food processing fields. .

Un premier dispositif 10 de distribution d'une composition fluide 12 selon l'invention est illustré par les figures 1 et 2. A first device 10 for dispensing a fluid composition 12 according to the invention is illustrated in FIGS. 1 and 2.
Ce dispositif 10 est destiné à former et à distribuer la composition fluide 12 à l'extérieur du dispositif 10 à partir d'un mélange hétérogène 14 contenu dans le dispositif 10. This device 10 is intended to form and distribute the fluid composition 12 outside the device 10 from a heterogeneous mixture 14 contained in the device 10.
La composition fluide 12 est destinée à former par exemple un gel, une crème, une mousse, une émulsion, une brume, un spray ou aérosol. Elle contient au moins un produit choisi parmi un produit biologiquement actif, un produit cosmétique, ou un produit comestible propre à être consommé. The fluid composition 12 is intended to form, for example, a gel, a cream, a mousse, an emulsion, a mist, a spray or an aerosol.

En variante, il s'agit d'huiles telles qu'une huile alimentaire, du type huile d'olive, huile de soja, huile de grains de raisin, huile de tournesol, ou toute autre huile extraite des végétaux. An edible product contained in the composition 12, suitable for consumption by a human being or an animal is advantageously purees of vegetables or fruits such as mango puree, pear puree, coconut puree, cream of onions, leeks, carrots, or other preparations that can mix several fruits or vegetables. Alternatively, it is oils such as a food oil, such as olive oil, soybean oil, grape seed oil, sunflower oil, or any other oil extracted from the plants.
La composition fluide 12 est avantageusement homogène, sans particules macroscopiques en suspension. Par « particules macroscopiques », on entend notamment une particule de dimension transversale maximale supérieure à 200 μηι, notamment supérieure à 500μηι. The fluid composition 12 is advantageously homogeneous, without macroscopic particles in suspension. By "macroscopic particles" is meant in particular a particle of maximum transverse dimension greater than 200 μηι, especially greater than 500μηι.
La composition fluide 12 se présente ainsi avantageusement sous la forme d'un premier fluide liquide pur, d'une solution d'un fluide dans un solvant liquide, ou d'une dispersion telle qu'une émulsion ou une suspension de fluide dans un liquide, les éléments dispersés étant invisibles à l'oeil nu. The fluid composition 12 is thus advantageously in the form of a first pure liquid fluid, a solution of a fluid in a liquid solvent, or a dispersion such as an emulsion or suspension of fluid in a liquid. , the scattered elements being invisible to the naked eye.
La viscosité de la composition fluide 12 est généralement comprise entre 500 mPa.s et 20000 mPa.s. En particulier, cette viscosité est comprise entre 2000 mPa.s et 15000 mPa.s. Cette viscosité est mesurée par la méthode suivante.
On utilise un viscosimètre de type Brookfield DV-II avec un mobile (Spindle) de taille (No.) 05. On place environ 150 g de composition dans un bêcher de 250 ml de volume, ayant un diamètre d'environ 7 cm de façon à ce que la hauteur du volume occupée par les 150 g de composition soit suffisante pour arriver à la jauge marquée sur le mobile. Ensuite, on démarre le viscosimètre sur une vitesse de 10 RPM et on attend que la valeur affichée sur l'écran soit stable. The viscosity of the fluid composition 12 is generally between 500 mPa.s and 20000 mPa.s. In particular, this viscosity is between 2000 mPa.s and 15000 mPa.s. This viscosity is measured by the following method. A Brookfield DV-II viscometer with a spindle of size (No.) 05 was used. About 150 g of composition were placed in a beaker of 250 ml volume, having a diameter of about 7 cm. that the height of the volume occupied by the 150 g of composition is sufficient to reach the gauge marked on the mobile. Then, we start the viscometer on a speed of 10 RPM and wait until the value displayed on the screen is stable.
Le mélange hétérogène 14 comporte un milieu continu 18 et une pluralité de particules en suspension 20. The heterogeneous mixture 14 comprises a continuous medium 18 and a plurality of suspended particles 20.
Le milieu continu 18 se présente ainsi avantageusement sous la forme d'un premier fluide liquide pur, d'une solution d'un fluide dans un solvant liquide, ou d'une dispersion telle qu'une émulsion ou une suspension de fluide dans un liquide, les éléments dispersés étant invisibles à l'oeil nu. The continuous medium 18 is thus advantageously in the form of a first pure liquid fluid, a solution of a fluid in a liquid solvent, or a dispersion such as an emulsion or suspension of fluid in a liquid. , the scattered elements being invisible to the naked eye.
Il peut former une solution plus ou moins visqueuse, un gel, une crème, ou une mousse, une émulsion, une brume, un spray ou aérosol. It can form a more or less viscous solution, a gel, a cream, or a mousse, an emulsion, a mist, a spray or an aerosol.
La viscosité du milieu 18 est généralement comprise entre 500 mPa.s et 20000 mPa.s. En particulier, cette viscosité comprise entre 2000mPa.s et 15000mPa.s. Cette viscosité est mesurée par la méthode décrite ci-dessus. The viscosity of the medium 18 is generally between 500 mPa.s and 20000 mPa.s. In particular, this viscosity is between 2000mPa.s and 15000mPa.s. This viscosity is measured by the method described above.
Le milieu 18 contient au moins un produit choisi parmi un produit biologiquement actif, un produit cosmétique, ou un produit comestible propre à être consommé. Ces produits sont décrits ci-dessus. Medium 18 contains at least one product selected from a biologically active product, a cosmetic product, or an edible product suitable for consumption. These products are described above.
Dans l'exemple représenté sur les figures 1 et 2, les particules dispersées 20 sont formées par des billes solides ou semi-solides. In the example shown in Figures 1 and 2, the dispersed particles 20 are formed by solid or semi-solid beads.
Les particules 20 sont disposées dans le milieu continu 18. The particles 20 are arranged in the continuous medium 18.
La fraction massique de particules 20 dans le milieu hétérogène 14, prise comme la masse totale des particules 20 par rapport à la somme des masses des particules 20 et du milieu continu 18 est supérieure à 1 %, avantageusement supérieure à 10%, notamment à 20% ou à 50%. The mass fraction of particles in heterogeneous medium 14, taken as the total mass of particles 20 relative to the sum of the masses of particles 20 and continuous medium 18 is greater than 1%, advantageously greater than 10%, especially 20%. % or 50%.
Les particules 20 sont macroscopiques. Elles sont ainsi visibles à l'œil nu. Le diamètre des particules 20 est par exemple supérieur à 1 mm, et est notamment compris entre 1 mm et 8 mm, notamment entre 2 mm et 5 mm. The particles are macroscopic. They are thus visible to the naked eye. The diameter of the particles 20 is for example greater than 1 mm, and is especially between 1 mm and 8 mm, in particular between 2 mm and 5 mm.
Les particules 20 sont avantageusement déformables, notamment déformables élastiquement ou plastiquement sur une plage de déformation supérieure à 5% en compression entre deux surfaces planes. The particles 20 are advantageously deformable, in particular deformable elastically or plastically over a deformation range greater than 5% in compression between two flat surfaces.
En variante, les particules 20 sont solides, et présentent une déformation très faible, notamment inférieure à 1 %.
La déformation des particules 20 est caractérisée par une augmentation de l'aire des particules 20 suite à l'application d'une masse sur une série de particules 20. In a variant, the particles are solid and have a very small deformation, in particular less than 1%. The deformation of the particles is characterized by an increase in the area of the particles following the application of a mass to a series of particles 20.
L'observation est réalisée à l'aide du montage suivant : The observation is made using the following editing:
Les échantillons comprenant six particules sont déposées sur une plaque en verre transparente. Une caméra Vého Discovery VMS 001 reliée à un ordinateur est placée de manière à pouvoir observer le dessous de la plaque de verre et donc les particules par transparence. The samples comprising six particles are deposited on a transparent glass plate. A Vého Discovery VMS 001 camera connected to a computer is placed so as to observe the underside of the glass plate and therefore the particles by transparency.
Le logiciel d'acquisition utilisé est Astra Image Webcam Video Grabber. Un premier cliché est enregistré afin de pouvoir mesurer l'aire initiale des particules. Ensuite une seconde plaque de verre est déposée sur les particules, et le poids est ajusté de manière à ce que la masse de la seconde plaque de verre plus le lest corresponde à 100 fois la masse de l'échantillon initial (soit 600 fois le poids d'une particule). Un second cliché est enregistré 5 minutes après avoir lesté la deuxième plaque de verre. Les clichés enregistrés sont par la suite exploités avec le logiciel ImageJ. La mesure des aires avant et après déformation sont obtenues en pixels. La valeur moyennée sur le nombre d'échantillons des rapports (aire finale - aire initiale) / aire initial correspond à la valeur de déformation. The acquisition software used is Astra Image Webcam Video Grabber. A first snapshot is recorded in order to measure the initial particle area. Then a second glass plate is deposited on the particles, and the weight is adjusted so that the mass of the second glass plate plus the ballast corresponds to 100 times the mass of the initial sample (600 times the weight of a particle). A second shot is recorded 5 minutes after weighting the second glass plate. The recorded snapshots are subsequently exploited with the ImageJ software. The measurement of the areas before and after deformation are obtained in pixels. The value averaged over the number of samples of the ratios (final area - initial area) / initial area corresponds to the deformation value.
Dans un premier mode de réalisation, les particules 20 sont homogènes. Elles sont par exemple formées par un produit solide continu tel que des polymères réticulés (PMMA, PLGA...), ou encore des solides (métal, oxyde métalliques) recouverts d'une couche de polymère déformable tels que les polymères précités. In a first embodiment, the particles are homogeneous. They are for example formed by a continuous solid product such as crosslinked polymers (PMMA, PLGA ...), or even solids (metal, metal oxide) covered with a deformable polymer layer such as the aforementioned polymers.
Dans la variante illustrée par les figures 1 et 2, au moins une partie des particules 20 est formée par des capsules comportant un cœur 22 fluide (voir figure 1 ) et une enveloppe extérieure 24 gélifiée. Les capsules sont avantageusement des capsules telles que décrites dans la demande de brevet WO2010/063937 de la Demanderesse. In the variant illustrated in Figures 1 and 2, at least a portion of the particles 20 is formed by capsules having a core 22 fluid (see Figure 1) and a gelled outer shell 24. The capsules are advantageously capsules as described in the patent application WO2010 / 063937 of the Applicant.
Dans cet exemple, chaque capsule est de forme sphérique et présente avantageusement un diamètre extérieur supérieur à 500 microns et avantageusement submillimétrique. In this example, each capsule is spherical in shape and advantageously has an outside diameter greater than 500 microns and advantageously submillimetric.
Le diamètre des capsules est généralement inférieur à 8 mm et compris notamment entre 1 mm et 5 mm. The diameter of the capsules is generally less than 8 mm and in particular between 1 mm and 5 mm.
Le cœur 22 contient au moins un fluide choisi avantageusement parmi un produit biologiquement actif, un produit cosmétique, ou un produit comestible propre à être consommé, tels qu'ils ont été décrits plus haut. The core 22 contains at least one fluid advantageously chosen from a biologically active product, a cosmetic product, or an edible product that can be consumed, as described above.
La viscosité du cœur 22 est notamment inférieure à 50000 mPa.s et de préférence inférieure à 30000 mPa.s. Le cœur 22 est à base d'une phase majoritairement aqueuse ou au contraire d'une phase majoritairement huileuse.
L'enveloppe gélifiée 24 des capsules (voir figure 1 ) comprend avantageusement un gel contenant de l'eau et au moins un polyélectrolyte réactif aux ions multivalents. Dans une variante avantageuse, l'enveloppe 24 contient en outre un agent tensioactif résultant de son procédé de fabrication. The viscosity of the core 22 is in particular less than 50000 mPa.s and preferably less than 30000 mPa.s. The core 22 is based on a predominantly aqueous phase or on the contrary a predominantly oily phase. The gelled envelope 24 of the capsules (see FIG. 1) advantageously comprises a gel containing water and at least one polyelectrolyte reactive with multivalent ions. In an advantageous variant, the envelope 24 further contains a surfactant resulting from its manufacturing process.
Par « polyélectrolyte réactif aux ions polyvalents », on entend, au sens de la présente invention, un polyélectrolyte susceptible de passer d'un état liquide dans une solution aqueuse à un état gélifié sous l'effet d'un contact avec une solution gélifiante contenant des ions multivalents tels que des ions d'un métal alcalino-terreux choisis par exemple parmi les ions calcium, les ions baryum, les ions magnésium. For the purposes of the present invention, the term "polyelectrolyte reactive with polyvalent ions" means a polyelectrolyte capable of passing from a liquid state in an aqueous solution to a gelled state under the effect of contact with a gelling solution containing multivalent ions such as ions of an alkaline earth metal chosen for example from calcium ions, barium ions, magnesium ions.
Dans l'état liquide, les chaînes individuelles de polyélectrolyte sont sensiblement libres de s'écouler les unes par rapport aux autres. Une solution aqueuse de 2% en masse de polyélectrolyte présente alors un comportement purement visqueux aux gradients de cisaillement caractéristiques du procédé de mise en forme. La viscosité de cette solution est entre 50 mPa.s et 20000 mPa.s avantageusement entre 3000 mPa.s et 15000 mPa.s mesurée par la méthode précédemment décrite. In the liquid state, the individual polyelectrolyte chains are substantially free to flow relative to one another. An aqueous solution of 2% by weight of polyelectrolyte then exhibits a purely viscous behavior at the shear gradients characteristic of the forming process. The viscosity of this solution is between 50 mPa.s and 20000 mPa.s, advantageously between 3000 mPa.s and 15000 mPa.s, measured by the method previously described.
Les chaînes individuelles de polyélectrolyte dans l'état liquide présentent avantageusement une masse molaire supérieure à 65000 g/moles. The individual polyelectrolyte chains in the liquid state advantageously have a molar mass greater than 65000 g / mol.
Dans l'état gélifié, les chaînes individuelles de polyélectrolyte forment, avec les ions multivalents, un réseau tridimensionnel cohérent qui retient le cœur 40 et empêche son écoulement. Les chaînes individuelles sont retenues les unes par rapport aux autres et ne peuvent pas s'écouler librement les unes par rapport aux autres. Dans cet état, la viscosité du gel formé est infinie. De plus le gel a un seuil de contrainte à l'écoulement. Ce seuil de contrainte est supérieur à 0,05 Pa. Le gel possède également un module d'élasticité non-nul et supérieur à 35 kPa. In the gelled state, the individual polyelectrolyte chains together with the multivalent ions form a coherent three-dimensional network which holds the core 40 and prevents its flow. The individual chains are held together and can not flow freely relative to each other. In this state, the viscosity of the formed gel is infinite. In addition, the gel has a threshold of stress to the flow. This stress threshold is greater than 0.05 Pa. The gel also has a modulus of elasticity that is non-zero and greater than 35 kPa.
Le gel tridimensionnel de polyélectrolyte contenu dans l'enveloppe 24 emprisonne de l'eau et l'agent tensioactif lorsqu'il est présent. La teneur massique du polyélectrolyte dans l'enveloppe 24 est par exemple comprise entre 0,5 % et 5 %. The three-dimensional gel of polyelectrolyte contained in the envelope 24 traps water and the surfactant when it is present. The mass content of the polyelectrolyte in the envelope 24 is for example between 0.5% and 5%.
Le polyélectrolyte est de préférence un polymère biocompatible inoffensif pour le corps humain. Il est par exemple produit biologiquement. The polyelectrolyte is preferably a biocompatible polymer that is harmless to the human body. It is for example produced biologically.
Avantageusement, il est choisi parmi les polysaccharides, polyélectrolytes de synthèse à base d'acrylates (polyacrylate de sodium, de lithium, de potassium ou d'ammonium, ou polyacrylamide), de polyélectrolytes de synthèse à base de sulfonates (poly(styrène sulfonate) de sodium, par exemple). Plus particulièrement, le polyélectrolyte est choisi parmi un alginate d'alcalino-terreux, tel qu'un alginate de sodium ou un alginate de potassium, une gellane ou une pectine.
Les alginates sont produits à partir d'algues brunes appelées « laminaires » , désignées par le terme anglais « sea weed ». Advantageously, it is chosen from polysaccharides, synthetic polyelectrolytes based on acrylates (sodium, lithium, potassium or ammonium polyacrylate, or polyacrylamide), synthetic polyelectrolytes based on sulfonates (poly (styrene sulfonate)). sodium, for example). More particularly, the polyelectrolyte is selected from an alkaline earth alginate, such as sodium alginate or potassium alginate, gellan or pectin. Alginates are produced from brown algae called "laminar", referred to as "sea weed".
De tels alginates présentent avantageusement une teneur en oc-L-guluronate supérieure à environ 50%, de préférence supérieure à 55%, voire supérieure à 60%. Such alginates advantageously have a content of α-L-guluronate greater than about 50%, preferably greater than 55%, or even greater than 60%.
L'agent tensioactif est avantageusement un tensioactif anionique, un tensioactif nonionique, un tensioactif cationique ou un mélange de ceux-ci. La masse moléculaire de l'agent tensioactif est comprise entre 1 50 g/mol et 10000 g/mol, avantageusement entre 250 g/mol et 1500 g/mol. The surfactant is preferably an anionic surfactant, a nonionic surfactant, a cationic surfactant or a mixture thereof. The molecular weight of the surfactant is between 1 50 g / mol and 10000 g / mol, advantageously between 250 g / mol and 1500 g / mol.
Dans le cas où le tensioactif est un tensioactif anionique, il est par exemple choisi parmi un alkylsulfate, un alkyle sulfonate, un alkylarylsulfonate, un alkylphosphate alcalin, un dialkylsulfosuccinate, un sel d'alcalino-terreux d'acides gras saturés ou non. Ces tensioactifs présentent avantageusement au moins une chaîne hydrocarbonée hydrophobe présentant un nombre de carbones supérieur à 5, voire 10 et au moins un groupement anionique hydrophile, tel qu'un sulfate, un sulfonate ou un carboxylate lié à une extrémité de la chaîne hydrophobe. In the case where the surfactant is an anionic surfactant, it is for example chosen from an alkyl sulphate, an alkyl sulphonate, an alkyl aryl sulphonate, an alkaline alkyl phosphate, a dialkyl sulphosuccinate, an alkaline earth salt of saturated or unsaturated fatty acids. These surfactants advantageously have at least one hydrophobic hydrocarbon chain having a number of carbons greater than 5 or even 10 and at least one hydrophilic anionic group, such as a sulphate, a sulphonate or a carboxylate linked to one end of the hydrophobic chain.
Dans le cas où le tensioactif est un tensioactif cationique, il est par exemple choisi parmi un sel d'halogénure d'alkyipyridium ou d'alkylammonium comme le chlorure ou le bromure de n-éthyldodecylammonium, le chlorure ou le bromure de cétylammonium (CTAB). Ces tensioactifs présentent avantageusement au moins une chaîne hydrocarbonée hydrophobe présentant un nombre de carbones supérieur à 5, voire 1 0 et au moins un groupement cationique hydrophile, tel qu'un cation d'ammonium quaternaire. In the case where the surfactant is a cationic surfactant, it is for example chosen from a salt of alkyipyridium or alkylammonium halide such as n-ethyldodecylammonium chloride or bromide, cetylammonium chloride or bromide (CTAB) . These surfactants advantageously have at least one hydrophobic hydrocarbon chain having a number of carbons greater than 5, or even 10, and at least one hydrophilic cationic group, such as a quaternary ammonium cation.
Dans le cas où le tensioactif est un tensioactif nonionique, il est par exemple choisi parmi des dérivés polyoxyéthylénés et/ou polyoxypropylénés des alcools gras, des acides gras, ou des alkylphénols, des arylphénols, ou parmi des alkyls glucosides, des polysorbates, des cocamides. In the case where the surfactant is a nonionic surfactant, it is for example chosen from polyoxyethylenated and / or polyoxypropylenated derivatives of fatty alcohols, fatty acids, or alkylphenols, arylphenols, or from alkyls glucosides, polysorbates, cocamides .
La teneur massique en agent tensioactif dans l'enveloppe 24 est supérieure à 0,001 % et est avantageusement supérieure à 0, 1 %. The mass content of surfactant in the envelope 24 is greater than 0.001% and is advantageously greater than 0.1%.
Dans cet exemple, l'enveloppe 24 est constituée exclusivement de polyélectrolyte, éventuellement d'agent tensioactif, et d'eau. La somme des teneurs massiques en polyélectrolyte, en agent tensioactif, et en eau est alors égale à 100%. In this example, the envelope 24 consists exclusively of polyelectrolyte, optionally surfactant, and water. The sum of the mass contents of polyelectrolyte, surfactant, and water is then equal to 100%.
En variante, chaque capsule est du type décrit dans la demande FR 10 61404 de la Demanderesse. Chaque capsule comporte alors un cœur 22 qui contient une goutte intermédiaire d'une phase intermédiaire placée au contact de l'enveloppe gélifiée 24. Le cœur 22 comporte au moins une goutte interne d'une phase interne disposée dans la goutte intermédiaire.
Avantageusement, les particules 20 sont mono-dispersées. Par « mono- dispersées », on entend qu'elles possèdent un coefficient de variation Cv en taille inférieure à 10%. In a variant, each capsule is of the type described in FR FR 61404. Each capsule then comprises a core 22 which contains an intermediate drop of an intermediate phase placed in contact with the gelled envelope 24. The core 22 comprises at least one internal drop of an internal phase disposed in the intermediate drop. Advantageously, the particles are mono-dispersed. By "monodisperse" is meant that they have a coefficient of variation C v in size less than 10%.
Pour calculer le coefficient de variation Cv, le diamètre moyen D des particules est par exemple mesuré par analyse d'une photographie d'un lot constitué de N particules, par un logiciel de traitement d'image (Image J). Typiquement, selon cette méthode, le diamètre est mesuré en pixel, puis rapporté en μηι, en fonction de la dimension du récipient contenant les particules. To calculate the coefficient of variation C v , the average diameter D of the particles is for example measured by analysis of a photograph of a batch consisting of N particles, by image processing software (Image J). Typically, according to this method, the diameter is measured in pixels, then reported in μηι, depending on the size of the container containing the particles.
De préférence, la valeur de N est choisie supérieure ou égale à 30, de sorte que cette analyse reflète de manière statistiquement significative la distribution de diamètres des particules de ladite émulsion. Preferably, the value of N is chosen greater than or equal to 30, so that this analysis reflects in a statistically significant manner the particle size distribution of said emulsion.
On mesure le diamètre D; de chaque particule, puis on obtient le diamètre moyenThe diameter D is measured ; of each particle, then we obtain the average diameter
D en calculant la moyenne arithmétique de ces valeurs D; : D by calculating the arithmetic mean of these D values ; :
1 N 1 N
A partir de ces valeurs D on peut également obtenir l'écart-type σ des diamètres des particules de la dispersi
From these values D one can also obtain the standard deviation σ of the diameters of the particles of the dispersite.
Pour caractériser la monodispersité des particules selon ce mode de l'invention, on peut calculer le coefficient de variation Cv :
To characterize the monodispersity of the particles according to this mode of the invention, the coefficient of variation C v can be calculated:
Le coefficient de variation des diamètres des particules de la population selon ce mode de l'invention est inférieur à 10%, de préférence inférieur à 5%. The coefficient of variation of the particle diameters of the population according to this mode of the invention is less than 10%, preferably less than 5%.
Dans un exemple particulier, le milieu continu 18 est formé par une solution gélifiée par exemple par un gel aqueux, notamment seul ou en combinaison, un gel d'acide hyaluronique, de xanthane, de polysachharides, de cellulose, de gomme de guar ou encore d'oligogéline. In a particular example, the continuous medium 18 is formed by a solution gelled for example by an aqueous gel, in particular alone or in combination, a gel of hyaluronic acid, xanthan, polysaccharides, cellulose, guar gum or else of oligogéline.
La viscosité du milieu continu 18 est supérieure à 1000 mPa.s, notamment comprise entre 3000 mPa.s et 10 000 mPa.s. The viscosity of the continuous medium 18 is greater than 1000 mPa.s, especially between 3000 mPa.s and 10 000 mPa.s.
Le gel est ainsi suffisamment visqueux pour permettre la suspension des particules 20. Il est cependant peu rhéofluidifiant pour permettre son aspiration à travers
le dispositif 10, tout en étant suffisamment rhéofluidifiant pour entraîner les particules 20 avec lui lors de sa distribution. The gel is thus sufficiently viscous to allow the suspension of the particles 20. It is, however, little rheofluidifier to allow its aspiration through the device 10, while being sufficiently rheofluidifier to drive the particles 20 with him during its distribution.
Comme illustré par les figures 1 et 2, le dispositif 10 comporte un récipient 30 contenant le mélange hétérogène 14, et un élément de délivrance 32 selon l'invention, monté dans le récipient 30 pour former la composition fluide 12 à partir du mélange hétérogène 14. As illustrated by FIGS. 1 and 2, the device 10 comprises a container 30 containing the heterogeneous mixture 14, and a delivery element 32 according to the invention, mounted in the container 30 to form the fluid composition 12 from the heterogeneous mixture 14 .
Le dispositif 10 comporte en outre un organe de distribution 34 de la composition fluide 12 hors du dispositif 10, raccordé à l'élément de délivrance 32. The device 10 further comprises a dispensing member 34 of the fluid composition 12 outside the device 10, connected to the delivery element 32.
Dans l'exemple illustré par les figures 1 et 2, le récipient 30 est formé par un contenant tubulaire 36 présentant un col 38 sur lequel est monté l'organe de distribution 34. In the example illustrated by FIGS. 1 and 2, the container 30 is formed by a tubular container 36 having a neck 38 on which the dispenser member 34 is mounted.
Le récipient 30 délimite un volume intérieur creux 40 accommodant le mélange 14 et l'élément de délivrance 32. The container 30 delimits a hollow interior volume 40 accommodating the mixture 14 and the delivery element 32.
Le volume intérieur creux 40 est par exemple compris entre 0,01 dm3 et 0,2 dm3, notamment entre 0,015 dm3 et 0,1 dm3. The hollow interior volume 40 is for example between 0.01 dm 3 and 0.2 dm 3 , especially between 0.015 dm 3 and 0.1 dm 3 .
Selon l'invention, l'élément de délivrance 32 comporte un conduit 42 de guidage de fluide, et un organe 44 de filtration tangentielle, disposé dans le conduit de guidage 42 pour former la composition fluide 12. According to the invention, the delivery element 32 comprises a fluid guide duct 42, and a tangential filtration member 44, disposed in the guide duct 42 to form the fluid composition 12.
Le conduit de guidage 42 s'étend à travers le volume intérieur 40, avantageusement jusqu'au col 38. Sa hauteur est généralement supérieure à 90 %, notamment supérieure à 95%, de la hauteur du récipient 30. The guide duct 42 extends through the interior volume 40, advantageously up to the neck 38. Its height is generally greater than 90%, especially greater than 95%, of the height of the container 30.
Le conduit de guidage 42 comporte un corps tubulaire creux 46 et un organe de fixation 48 sur le récipient 30. L'organe de fixation 48 est configuré pour permettre au conduit de guidage 42 de reposer sur le col 38 du récipient 30 et pour avoir une liaison directe et étanche avec l'organe de distribution 34. The guide duct 42 comprises a hollow tubular body 46 and a fastener 48 on the container 30. The fixing member 48 is configured to allow the guide duct 42 to rest on the neck 38 of the container 30 and to have direct and sealed connection with the dispensing member 34.
Il délimite un passage central 50 définissant un axe A-A' de circulation de fluide à travers le conduit 42. Le conduit 42 délimite en outre une ouverture amont 52 de prélèvement de mélange hétérogène 14 et une ouverture aval 54 de délivrance de composition fluide 12, par lesquelles débouche le passage central 50. It delimits a central passage 50 defining an axis AA 'of fluid circulation through the conduit 42. The conduit 42 further delimits an upstream opening 52 for taking up heterogeneous mixture 14 and a downstream opening 54 for delivering a fluid composition 12, through which opens the central passage 50.
Le corps tubulaire creux 46 est par exemple formé à partir d'une matière plastique, avantageusement souple. Dans cet exemple, l'organe de fixation 48 comprend une collerette montée en appui sur le col 38 du récipient 30. The hollow tubular body 46 is for example formed from a plastic material, preferably flexible. In this example, the fastener 48 comprises a flange mounted to bear on the neck 38 of the container 30.
Dans l'exemple représenté sur les figures 1 et 2, le passage central 50 présente une section sensiblement constante. Il s'étend de manière linéaire le long de l'axe A-A', de manière verticale sur les figures 1 et 2. Son étendue transversale est supérieure au diamètre moyen des particules 20, notamment supérieure à 2,5 fois le diamètre moyen.
Selon l'invention, l'organe de filtration 44 comporte au moins une paroi ajourée de filtration 56 délimitant des ouvertures de filtration 58, formant un angle non nul et avantageusement supérieur à 10 ° avec une perpendiculaire à l'axe A-A' de circulation. In the example shown in Figures 1 and 2, the central passage 50 has a substantially constant section. It extends linearly along the axis A-A ', vertically in Figures 1 and 2. Its transverse extent is greater than the average diameter of the particles 20, especially greater than 2.5 times the average diameter . According to the invention, the filtering member 44 comprises at least one perforated filter wall 56 delimiting filtration openings 58, forming a non-zero angle and advantageously greater than 10 ° with a perpendicular to the axis AA 'of circulation.
Dans l'exemple représenté sur les figures 1 et 2, la paroi ajourée de filtration 56 est de forme conique. Elle forme ainsi un angle supérieur à 30 °, avantageusement supérieur à 45° avec la perpendiculaire à l'axe A-A' de circulation. Dans cet exemple, la paroi ajourée de filtration 56 comprenant une pluralité d'ouvertures 58 est en outre inclinée par rapport à l'axe A-A' de circulation, pour assurer une filtration tangentielle. In the example shown in Figures 1 and 2, the perforated filter wall 56 is conical. It thus forms an angle greater than 30 °, advantageously greater than 45 ° with the perpendicular to the axis A-A 'of circulation. In this example, the perforated filter wall 56 comprising a plurality of openings 58 is further inclined with respect to the axis A-A 'of circulation, to ensure a tangential filtration.
La paroi ajourée de filtration 56 fait saillie vers l'aval dans le passage central 50. Elle présente une base 60 de section supérieure ou égale à celle de l'ouverture aval 54 pour entourer l'ouverture aval 54 et une extrémité libre 62 disposée dans le passage 50. The perforated filter wall 56 projects downstream into the central passage 50. It has a base 60 of section greater than or equal to that of the downstream opening 54 to surround the downstream opening 54 and a free end 62 disposed in the passage 50.
Ainsi, l'organe de filtration 44 est agencé dans le conduit de guidage 42 pour que tout le mélange hétérogène 14 introduit dans le passage central 50 à travers l'ouverture amont 52 passe à travers la paroi ajourée 56 et ses ouvertures 58, avant d'atteindre l'ouverture aval 54. Ceci permet la formation de la composition fluide 12 et la rétention sur la paroi ajourée 56 des résidus résultant de cette formation. Thus, the filtration member 44 is arranged in the guide duct 42 so that all the heterogeneous mixture 14 introduced into the central passage 50 through the upstream opening 52 passes through the perforated wall 56 and its openings 58, before to reach the downstream opening 54. This allows the formation of the fluid composition 12 and the retention on the perforated wall 56 residues resulting from this formation.
Aucune partie du mélange hétérogène 14 ne peut ainsi atteindre l'ouverture aval 54 sans être passée par la paroi ajourée de filtration 56. No part of the heterogeneous mixture 14 can thus reach the downstream opening 54 without passing through the perforated filter wall 56.
Dans une variante (non représentée), l'organe de filtration 44 est de forme cylindrique d'axe A-A'. La paroi de filtration 56 comprend ainsi au moins un tronçon parallèle à l'axe A-A', propre à assurer une filtration tangentielle. In a variant (not shown), the filter member 44 is cylindrical in shape of axis A-A '. The filter wall 56 thus comprises at least one section parallel to the axis A-A ', suitable for tangential filtration.
La longueur de l'organe de filtration 44 est supérieure à 50 % de la longueur du passage central 50. The length of the filter member 44 is greater than 50% of the length of the central passage 50.
Les ouvertures de filtration 58 sont réparties le long de l'axe A-A'. Les dimensions transversales des ouvertures 58 sont choisies pour assurer une rétention efficace des résidus produits lors de la désagrégation des particules 20, tout en évitant les phénomènes de bouchage et en assurant une vitesse d'aspiration adéquate au-delà des pressions exercées par l'organe de distribution 34. The filter openings 58 are distributed along the axis A-A '. The transverse dimensions of the openings 58 are chosen to ensure effective retention of the residues produced during the disintegration of the particles 20, while avoiding clogging phenomena and ensuring an adequate suction velocity beyond the pressures exerted by the organ distribution 34.
Avantageusement, la dimension transversale des ouvertures 58 est inférieure au diamètre moyen des particules 20, et est avantageusement inférieure au tiers du diamètre moyen des particules 20. Advantageously, the transverse dimension of the openings 58 is smaller than the average diameter of the particles 20, and is advantageously less than one third of the average diameter of the particles 20.
L'organe de distribution 34 est par exemple formé par une pompe 80 propre à provoquer une aspiration du milieu hétérogène 14 dans l'élément de délivrance 32, puis à faire passer ce milieu 14 à travers l'organe de filtration 44 pour former la composition 12, et enfin à convoyer la composition 12 jusqu'à un orifice de distribution 82 situé sur l'organe 34 vers l'extérieur du dispositif 10.
La pompe est par exemple du type à bille, à clapet, à membrane, voire même à piston. The dispensing member 34 is for example formed by a pump 80 capable of causing aspiration of the heterogeneous medium 14 into the delivery element 32, then passing this medium 14 through the filtration member 44 to form the composition 12, and finally to convey the composition 12 to a dispensing orifice 82 located on the member 34 towards the outside of the device 10. The pump is for example of the ball type, valve, diaphragm, or even piston.
Dans cet exemple, l'organe de distribution 34 est raccordé à l'élément de délivrance 32. Ainsi, l'ouverture aval 54 débouche dans l'organe de distribution 34, avantageusement dans un canal 84 de distribution raccordant l'ouverture aval 54 à l'orifice de distribution 82. In this example, the dispensing member 34 is connected to the delivery element 32. Thus, the downstream opening 54 opens into the dispenser member 34, advantageously into a distribution channel 84 connecting the downstream opening 54 to the dispensing orifice 82.
Le fonctionnement du premier dispositif 10 selon l'invention va maintenant être décrit. The operation of the first device 10 according to the invention will now be described.
Initialement, le dispositif 10 est fourni. Dans son volume intérieur 40, le récipient 30 contient le mélange hétérogène 14 comprenant les particules 20 dispersées dans le milieu 18. L'organe de distribution 34 est inactif. L'élément de délivrance 32 plonge dans le mélange 14. L'ouverture amont 52 s'ouvre dans le mélange 14. Initially, the device 10 is provided. In its interior volume 40, the container 30 contains the heterogeneous mixture 14 comprising the particles 20 dispersed in the medium 18. The dispensing member 34 is inactive. The delivery element 32 dips into the mixture 14. The upstream opening 52 opens into the mixture 14.
Lorsque l'utilisateur souhaite distribuer la composition fluide 12, il actionne l'organe de distribution 34. When the user wishes to dispense the fluid composition 12, he actuates the dispensing member 34.
L'organe de distribution 34 engendre alors une aspiration qui se propage à travers le volume intérieur 50 de l'élément de délivrance 32. The dispensing member 34 then generates an aspiration which propagates through the internal volume 50 of the delivery element 32.
Le mélange 14 est alors pompé à travers l'ouverture amont 52 et remonte dans le corps tubulaire creux 46 du conduit de guidage 42 jusqu'à l'organe de filtration 44. The mixture 14 is then pumped through the upstream opening 52 and back into the hollow tubular body 46 of the guide duct 42 to the filtration member 44.
Dans un premier mode de réalisation, lorsque les particules 20 sont rigides, elles se bloquent contre la paroi 56 dans l'espace intermédiaire délimité entre la paroi ajourée 56 et le corps 46 ce du conduit 42. Seul le milieu homogène 18 liquide passe à travers les ouvertures 58 de filtration. Le milieu homogène 18 forme ainsi la composition fluide 12 qui remonte à travers l'ouverture aval 54, le canal de distribution 84. Cette composition est extraite à travers l'orifice de distribution 82 hors du dispositif 10 par exemple sous forme d'un jet ou d'un spray. In a first embodiment, when the particles 20 are rigid, they block against the wall 56 in the intermediate space delimited between the perforated wall 56 and the body 46 of the duct 42. Only the homogeneous medium 18 liquid passes through the openings 58 of filtration. The homogeneous medium 18 thus forms the fluid composition 12 which rises through the downstream opening 54, the distribution channel 84. This composition is extracted through the dispensing orifice 82 out of the device 10, for example in the form of a jet or a spray.
Dans une variante, les particules 20 se désagrègent au contact de la paroi ajourée 56. Leur contenu passe à travers les ouvertures 58 et forme, par mélange avec le milieu 18, la composition fluide 12. Le résidu solide issu de la désagrégation des particules 20 est bloqué par la paroi ajourée 56. In a variant, the particles 20 disintegrate in contact with the perforated wall 56. Their contents pass through the openings 58 and form, by mixing with the medium 18, the fluid composition 12. The solid residue resulting from the disintegration of the particles 20 is blocked by the perforated wall 56.
L'élément de délivrance 32 selon l'invention filtre donc très efficacement un mélange hétérogène 14 pour former une composition fluide 12 propre à être distribuée dans un organe de distribution 34 standard et de faible coût. The delivery element 32 according to the invention thus very effectively filters a heterogeneous mixture 14 to form a fluid composition 12 to be distributed in a standard dispensing member 34 and low cost.
Par ailleurs, la fourniture d'un organe de filtration 44 produisant une filtration tangentielle évite le bouchage rapide de cet organe 44 et autorise la distribution de la totalité du mélange 14 contenu dans le récipient 30, sans risque de bouchage.
Un deuxième dispositif 1 10 selon l'invention est illustré par les figures 3 à 6. À la différence du premier dispositif 10, le conduit de guidage 42 de l'élément de délivrance 32 définit une restriction amont 1 12, s'étendant entre l'ouverture amont 52 et l'organe de filtration 44, et un tronçon aval 1 14 d'étendue transversale supérieure à l'étendue transversale de la restriction amont 1 12. Furthermore, the provision of a filter member 44 producing a tangential filtration avoids the rapid closure of this member 44 and allows the distribution of all the mixture 14 contained in the container 30, without risk of clogging. A second device 10 according to the invention is illustrated in FIGS. 3 to 6. In contrast to the first device 10, the guide duct 42 of the delivery element 32 defines an upstream restriction 1 12, extending between upstream opening 52 and the filter member 44, and a downstream section 1 14 of transverse extent greater than the transverse extent of the upstream restriction 1 12.
Avantageusement, la restriction amont 1 12 présente une section transversale intérieure constante. De préférence, l'étendue transversale de la restriction 1 12 est comprise entre une fois et deux fois le diamètre moyen des particules 20. Advantageously, the upstream restriction 1 12 has a constant inner cross section. Preferably, the transverse extent of the restriction 112 is between one and two times the mean diameter of the particles 20.
Dans l'exemple illustré par la figure 6, la restriction amont 1 12 comporte en outre une saillie radiale interne 1 16 destinée à désagréger les particules 20 pour homogénéiser le milieu hétérogène 14. In the example illustrated in FIG. 6, the upstream restriction 1 12 furthermore includes an internal radial projection 116 intended to break up the particles 20 in order to homogenize the heterogeneous medium 14.
La saillie radiale interne 1 16 est avantageusement annulaire. Elle fait saillie à partir de la paroi du conduit 42 définissant la restriction 1 12. Elle définit une lumière centrale 1 18 de passage du milieu 14, d'étendue transversale inférieure au diamètre moyen des particules 20 (voir figure 6). The internal radial projection 1 16 is preferably annular. It projects from the wall of the conduit 42 defining the restriction 1 12. It defines a central lumen 1 18 through which the medium 14 passes, with a transverse extension smaller than the average diameter of the particles 20 (see FIG. 6).
La hauteur de la restriction 1 12 est inférieure à la hauteur du tronçon aval 1 14, prises le long de l'axe A-A'. Cette hauteur est avantageusement inférieure à 50 % de la hauteur du tronçon aval 1 14, notamment inférieure à 20% de la hauteur du tronçon aval 1 14. The height of the restriction 1 12 is less than the height of the downstream section 1 14, taken along the axis A-A '. This height is advantageously less than 50% of the height of the downstream section 1 14, especially less than 20% of the height of the downstream section 1 14.
Le tronçon aval 1 14 reçoit l'organe de filtration 44. Dans cet exemple, l'extrémité libre 62 de la paroi ajourée 56 est située à distance axialement de la restriction 1 12 le long de l'axe A-A'. The downstream section 1 14 receives the filter member 44. In this example, the free end 62 of the perforated wall 56 is located at an axial distance from the restriction 1 12 along the axis A-A '.
L'étendue transversale minimale du tronçon aval 1 14 est supérieure à1 ,5, notamment supérieure à 2,5 fois le diamètre moyen des particules 20. Elle est ainsi supérieure à 200%, notamment 300 % de l'étendue transversale minimale de la restriction 1 12. The minimum transverse extent of the downstream section 1 14 is greater than 1.5, in particular greater than 2.5 times the average diameter of the particles 20. It is thus greater than 200%, in particular 300% of the minimum transverse extent of the restriction. 1 12.
Dans cet exemple, le tronçon aval 1 14 présente une section transversale intérieure sensiblement constante. In this example, the downstream section 1 14 has a substantially constant inner cross section.
Le fonctionnement du deuxième dispositif selon l'invention 1 10 diffère du fonctionnement du premier dispositif 10 selon l'invention en ce que le passage des particules 20 dans la restriction 1 12 aligne les particules 20 pour les placer avantageusement en file indienne, ce qui facilite leur aspiration. Puis, la saillie 1 16 présente dans la restriction 1 12 produit leur désagrégation. The operation of the second device according to the invention 1 10 differs from the operation of the first device 10 according to the invention in that the passage of the particles 20 in the restriction 1 12 aligns the particles 20 to advantageously place them in single file, which facilitates their aspiration. Then, the projection 1 16 present in the restriction 1 12 produces their disintegration.
En particulier, lorsque les particules sont des billes comprenant un cœur 22 et une enveloppe 24, l'enveloppe 24 des particules 20 se rompt dans la restriction 1 12 au passage de la saillie 1 16, libérant le cœur 22.
Le cœur 22 se mélange donc au milieu 18 pour former la composition fluide 12 qui passe à travers l'organe de filtration 44. L'enveloppe 24 forme un résidu 120 semi-solide qui est retenu par la paroi de filtration 56 sans passer à travers les ouvertures 58. In particular, when the particles are beads comprising a core 22 and an envelope 24, the envelope 24 of the particles 20 breaks in the restriction 1 12 to the passage of the projection 1 16, releasing the heart 22. The core 22 thus mixes with the medium 18 to form the fluid composition 12 which passes through the filtration member 44. The envelope 24 forms a semi-solid residue 120 which is retained by the filtration wall 56 without passing through the openings 58.
L'élément de délivrance 32 est donc efficace, à la fois pour former la composition fluide 12 par libération du coeur 22 dans la restriction 1 12 et pour retenir de manière très efficace le résidu 120 restant de l'enveloppe 24. The delivery element 32 is therefore effective both for forming the fluid composition 12 by releasing the core 22 in the restriction 1 12 and for very effectively retaining the remaining residue 120 of the envelope 24.
En particulier, le résidu 120 des enveloppes 24 est retenu petit à petit dans la partie supérieure de l'organe de filtration 44. Il s'accumule ainsi sans boucher totalement l'organe de filtration 44, jusqu'à ce que tout le contenu du dispositif de distribution 1 10 soit utilisé. In particular, the residue 120 of the envelopes 24 is held little by little in the upper part of the filtering member 44. It thus accumulates without completely clogging the filtering member 44, until all the contents of the dispensing device 1 10 is used.
En variante, au moins une partie des particules 20 se désagrègent lors du passage dans la restriction 1 12, au contact de la saillie 1 16, et au moins une partie des particules 20 se désagrègent au contact de l'organe de filtration 44. Encore en variante, les particules 20 se désagrègent partiellement lors du passage dans la restriction 1 12, au contact de la saillie 1 16, et finissent de se désagréger au contact de l'organe de filtration 44. As a variant, at least a portion of the particles 20 disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and at least a portion of the particles 20 disintegrate in contact with the filter member 44. alternatively, the particles 20 partially disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and end to disintegrate in contact with the filter member 44.
L'aspiration fournie par l'organe de distribution 34, notamment lorsque cet organe 34 est une pompe, est ainsi constante au cours de l'utilisation. Une composition fluide 14 homogène, sans aucun débris est ainsi délivrée par l'orifice de distribution 82, sans produire de débris défavorables à la sensation d'utilisation au toucher de la composition délivrée, par exemple sur la peau d'un utilisateur, ou produire des débris pouvant boucher l'organe de distribution The suction provided by the dispenser member 34, especially when this member 34 is a pump, is thus constant during use. A fluid composition 14 homogeneous, without any debris is thus delivered through the dispensing orifice 82, without producing debris unfavorable to the feel of use to the touch of the composition delivered, for example on the skin of a user, or produce debris that can block the dispenser member
Avantageusement, le volume de la partie amont du passage central 50 située en amont de l'organe de filtration 44 dans le passage central 50 est supérieur, et est notamment supérieur à 1 ,5 fois le volume maximal des résidus 120 destinés à être récupérés lors de la désagrégation des particules 20 en suspension. Advantageously, the volume of the upstream portion of the central passage 50 situated upstream of the filtration member 44 in the central passage 50 is greater, and is in particular greater than 1.5 times the maximum volume of the residues 120 intended to be recovered during of the disintegration of the particles in suspension.
Le volume maximal des résidus 120 est par exemple estimé par la somme de tous les volumes des enveloppes 24 des particules 20 contenues dans le mélange hétérogène 14, reçues au sein du récipient 30. The maximum volume of the residues 120 is for example estimated by the sum of all the volumes of the envelopes 24 of the particles 20 contained in the heterogeneous mixture 14, received within the container 30.
Le volume libre dans le filtre à peaux permet ainsi de stocker l'ensemble des résidus semi-solides résultant de la désagrégation et filtration du mélange hétérogène de départ. The free volume in the skin filter thus makes it possible to store all the semi-solid residues resulting from the disintegration and filtration of the heterogeneous starting mixture.
Dans tout ce qui précède, le terme « désagréger » signifie de préférence que les particules sont déchirées, explosées, ouvertes, et/ou cassées, perdant ainsi leur intégrité et libérant le cas échéant leur contenu, par opposition à la rupture d'un amas de particules pour obtenir des particules libres conservant leur intégrité propre.
Comme indiqué précédemment, le volume délimité par le passage central et l'organe de filtration 56 est supérieur à 1 ,5 le volume maximal occupé par l'ensemble des résidus 120 contenus dans le récipient 30. In all of the above, the term "disaggregate" preferably means that the particles are torn, exploded, opened, and / or broken, thereby losing their integrity and releasing where appropriate their contents, as opposed to breaking a clump. of particles to obtain free particles maintaining their integrity. As indicated above, the volume delimited by the central passage and the filtering member 56 is greater than 1.5 the maximum volume occupied by all the residues 120 contained in the container 30.
Par ailleurs, la surface de chaque ouverture de filtration 58 est inférieure à la surface minimale de chaque résidu 120. On the other hand, the area of each filter opening 58 is smaller than the minimum area of each residue 120.
Les ouvertures de filtration 58 sont avantageusement de forme allongée, avec la plus petite des dimensions, ici la largeur, inférieure au quart du diamètre des particules 20. The filtration openings 58 are advantageously of elongate shape, with the smallest dimension, here the width, less than a quarter of the diameter of the particles 20.
Ainsi, les ouvertures ont une surface importante, ce qui permet une bonne restitution du produit à délivrer, mais sont aussi suffisamment fines pour empêcher les résidus 120 de passer à travers le filtre, même si ceux-ci se replient sur eux-mêmes. Thus, the openings have a large surface, which allows a good return of the product to be delivered, but are also thin enough to prevent residues 120 to pass through the filter, even if they fold on themselves.
De préférence, la surface totale des ouvertures de filtration 58 est supérieure à 0,2 % et notamment inférieure à 10% de la surface totale des résidus 120 contenus dans le récipient 30. Preferably, the total area of the filtration openings 58 is greater than 0.2% and especially less than 10% of the total surface of the residues 120 contained in the container 30.
Dans tout ce qui précède, le terme « surface » appliqué à un résidu 120 signifie la surface maximale parmi l'ensemble des surfaces mesurées sur l'ensemble des projections de ce résidu 120 sur un plan, avantageusement sur la paroi de filtration 56 de l'organe de filtration 44. In all of the above, the term "surface" applied to a residue 120 means the maximum surface area of all the surfaces measured over all the projections of this residue 120 on a plane, advantageously on the filter wall 56 of the filtering member 44.
Comme illustré sur la figure 3, l'extrémité libre 62 de la paroi ajourée de filtration 56 est à l'écart axialement de l'ouverture amont 52.
As illustrated in FIG. 3, the free end 62 of the perforated filter wall 56 is axially spaced from the upstream opening 52.
