Description

La présente invention a trait à un ensemble permettant la distribution d'une composition formée d'au moins deux phases, selon un rapport variable de concentration desdites phases. L'invention vise la distribution de compositions formées d'au moins deux phases non miscibles entre elles et de densité différentes. L'ensemble selon l'invention peut faire l'objet de nombreuses applications, notamment cosmétiques (parfums, produits capillaires, produits de soin de la peau, etc.) pharmaceutiques, dermatologiques, ou alimentaires.The present invention relates to an assembly allowing the distribution of a composition formed from at least two phases, according to a variable ratio of concentration of said phases. The invention relates to the distribution of compositions formed from at least two immiscible phases of density different. The assembly according to the invention can be the subject of numerous applications, especially cosmetics (perfumes, hair products, skin care, etc.) pharmaceutical, dermatological, or food.

Les distributeurs de type utilisant un récipient à taille variable, surmonté d'une pompe sans reprise d'air, généralement appelée pompe "airless" sont connus, et ont été largement utilisés, notamment dans le domaine de la cosmétique pour la distribution de produits de soin sous forme d'une seule phase, généralement liquide, notamment de laits corporels, de produits hydratants, ou de produits de protection solaire. De tels distributeurs sont particulièrement avantageux en ce qu'ils permettent notamment de maintenir le produit isolé de l'air.Type dispensers using a variable size container, topped with a pump without return air, generally called "airless" pump are known, and have been widely used, especially in the field of cosmetics for the distribution of care products in the form of a single phase, generally liquid, especially body milks, moisturizers, or sun protection products. Such distributors are particularly advantageous in that they make it possible in particular to keep the product isolated from the air.

Les compositions à deux ou plusieurs phases, notamment une phase aqueuse et une phase huileuse sont connues dans le domaine de la cosmétique, notamment dans le domaine des bains de bouche, des lotions de soin, des lotions solaires, des nettoyants pour la peau, des démaquillants. Pour toutes ces applications, les compositions sont sous forme de phases séparées, soit pour des raisons esthétiques (deux couleurs différentes), soit pour des raisons d'incompatibilité de composés de chacune des phases. Dans tous les cas, ces compositions sont appliquées uniquement sous forme mélangée des phases qui la constituent, soit au moyen de distributeurs à pompe avec reprise d'air, soit au moyen de flacons sans pompe de distribution, et comportant généralement des parois souples de manière à expulser le produit.Compositions with two or more phases, in particular an aqueous phase and an oily phase are known in the field of cosmetics, especially in the field of mouthwashes, treatment lotions, sun lotions, skin cleansers, makeup removers. For all these applications, the compositions are in the form of separate phases, ie for aesthetic reasons (two different colors), either for reasons of incompatibility of compounds of each of the phases. In any case, these compositions are applied only in mixed form of the phases which constitute it, either by means of pump distributors with air intake, either by means of bottles without dispensing pump, and comprising generally flexible walls so as to expel the product.

Dans le domaine de la cosmétique, des études de comportements ont montré que bon nombre de consommatrices utilisent, ou souhaiteraient pouvoir utiliser, notamment à différents moments de la journée, des parfums de force différentes ou ayant des notes différentes. Ainsi, elles utiliseraient un parfum plutôt léger le matin, et/ou au bureau, et un parfum plus corsé pour le soir. De telles habitudes de consommation entraínent inévitablement la multiplication des flacons (un pour chaque parfum différent), ce qui d'un point de vue du transport, notamment dans un sac à mains, n'est pas sans poser de problèmes. En outre, quoi qu'il en soit, le choix ne peut se faire que parmi un nombre limité de possibilités.In the field of cosmetics, behavior studies have shown that many consumers are using, or would like to be able to use, especially at different times of the day, strong scents different or with different notes. So they would use a scent rather light in the morning, and / or in the office, and a more full-bodied scent for the evening. Of such consumption habits inevitably lead to multiplication bottles (one for each different fragrance), which from a transport, especially in a handbag, is not without problems. Furthermore, in any event, the choice can only be made from a limited number of possibilities.

Toujours dans le domaine des parfums, l'application d'une eau de parfum, généralement en phase hydroalcoolique, peut être jugée agressive sur la peau. Il serait dans ces conditions, souhaitable de faire suivre cette application, d'une application d'un produit aux vertus apaisantes, notamment à base d'extrait d'avoine ou d'allantoïne. Encore une fois, cela nécessite de la part de l'utilisatrice qu'elle dispose, en particulier dans son sac à main, de deux ou plusieurs flacons différents. En outre, cela multiplie les gestes d'application, et de ce fait, augmente le temps d'application.Still in the field of perfumes, the application of an eau de parfum, generally in the hydroalcoholic phase, can be considered aggressive on the skin. Under these conditions, it would be desirable to follow this application with a application of a product with soothing properties, in particular based on extract oats or allantoin. Again, this requires from the user that she has, in particular in her handbag, two or several different vials. In addition, this multiplies the gestures of application, and therefore, increases the application time.

De manière plus générale, dans le domaine de la cosmétique, il existe un bon nombre de produits pour lesquels il serait souhaitable, dans certains cas, de combiner l'application, avec l'application d'un produit ayant des propriétés complémentaires ou différentes. C'est la cas notamment de certains produits capillaires ou de traitement de la peau qui pourraient être utilisés en combinaison avec des pigments de coloration (de la peau ou des cheveux), et ce, en une concentration variable en fonction de la coloration voulue ou du maquillage voulu.More generally, in the field of cosmetics, there is a good number of products for which it would be desirable, in some cases, to combine the application, with the application of a product with properties complementary or different. This is particularly the case for certain products capillaries or skin treatment that could be used in combination with coloring pigments (of the skin or hair), and this, in a variable concentration depending on the desired color or the wanted makeup.

Ces problèmes d'application combinée ou séparée de deux produits complémentaires ou différents, se posent également dans des domaines autres que la cosmétique. A titre d'exemple, on peut citer la pharmacie, la dermatologie, ou l'alimentaire. These problems of combined or separate application of two products complementary or different, also arise in other areas than cosmetics. By way of example, mention may be made of the pharmacy, the dermatology, or food.

Aussi, est-ce un des objets de l'invention que de réaliser un ensemble unitaire permettant l'application combinée ou séparée de deux ou plusieurs produits à actions complémentaires ou différentes.It is therefore one of the objects of the invention to produce a unitary assembly allowing the combined or separate application of two or more products to complementary or different actions.

C'est un autre objet de l'invention que de réaliser un ensemble unitaire permettant l'application de la phase principale d'une composition, éventuellement combinée avec une phase secondaire de ladite composition, de manière à modifier les propriétés de la phase principale, ou à lui conférer de nouvelles propriétés, la concentration de la phase secondaire dans la composition distribuée pouvant être choisie à volonté.It is another object of the invention to produce a unitary assembly allowing the application of the main phase of a composition, optionally combined with a secondary phase of said composition, so as to modify the properties of the main phase, or to give it new properties, the concentration of the secondary phase in the distributed composition can be chosen at will.

C'est encore un objet de l'invention que de permettre la réalisation d'un ensemble permettant la distribution d'une composition selon un rapport de concentrations variable des phases constituant ladite composition.It is also an object of the invention to allow the realization of a set allowing the distribution of a composition according to a ratio of variable concentrations of the phases constituting said composition.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description which follows.

De manière surprenante, la demanderesse à constaté qu'un distributeur du type à volume variable équipé d'une pompe sans reprise d'air, en combinaison avec une composition à au moins deux phases non miscibles et de densité différentes, permettait de réaliser un ensemble autorisant notamment les fonctionnalités recherchées, telles que décrites précédemment.Surprisingly, the Applicant has found that a distributor of the variable volume type equipped with a pump without return air, in combination with a composition with at least two immiscible phases and of density different, made it possible to produce a set allowing in particular the sought-after functionalities, as described above.

Selon l'invention, les objets évoqués précédemment sont atteints en réalisant un ensemble "airless" comprenant a) un récipient à volume variable sur lequel est montée une pompe sans reprise d'air et b) une composition disposée à l'intérieur du récipient, et formée d'au moins deux phases non miscibles entre elles et ayant des densités différentes, l'une au moins des phases étant liquide.According to the invention, the objects mentioned above are achieved by making an "airless" assembly comprising a) a variable volume container on which is mounted a pump without air intake and b) a composition arranged to inside the container, and formed of at least two immiscible phases between them and having different densities, at least one of the phases being liquid.

Un récipient à volume variable au sens de la présente invention désigne un récipient dont le volume diminue au fur et à mesure de la distribution du produit qu'il contient. La réduction du volume du récipient est la conséquence de la dépression qui résulte, lors de chaque distribution, de la diminution du volume de produit à l'intérieur du récipient, lequel volume distribué n'est pas remplacé par un volume d'air correspondant, en raison de l'absence de reprise d'air. En effet, la pompe est montée de manière à ne pas autoriser de reprise d'air à l'intérieur du récipient, apte à compenser la diminution de volume de produit à l'intérieur du récipient. La pompe peut être du type à précompression, de manière à, le cas échéant, favoriser le mélange des deux phases.A variable volume container within the meaning of the present invention designates a container whose volume decreases as the product is dispensed it contains. The reduction in the volume of the container is the consequence of the depression resulting from each decrease in volume of product inside the container, which dispensed volume is not replaced by a corresponding air volume, due to the absence of air intake. In Indeed, the pump is mounted so as not to allow return air to inside the container, able to compensate for the decrease in volume of product to inside the container. The pump can be of the precompression type, of in such a way as to favor the mixing of the two phases.

La composition selon l'invention est constituée d'au moins deux phases qui ne sont pas miscibles de façon permanente. Il peut s'agir par exemple, de deux phases huileuses non miscibles et de densité différentes, d'une phase huileuse et d'une phase aqueuse ou d'une phase huileuse et d'une phase hydroalcoolique. Ainsi, en raison de la différence de densité entre les deux phases non miscibles, la phase lourde va se déposer dans le fond du récipient, tandis que la phase légère va surnager au dessus de la phase lourde. La séparation des phases se fait plus ou moins rapidement en fonction de la différence de densité entre les deux phases. En agitant le contenu du récipient, il se forme un "mélange" plus ou moins homogène des deux phases sous forme d'une dispersion, d'une suspension ou d'une émulsion. En laissant reposer l'ensemble, les phases se "démélangent" ou se séparent sous l'effet de leurs différences de densité. En fonction de la position du récipient, il est possible de distribuer soit l'une des phases, soit l'autre, soit un mélange des deux. En pouvant ainsi jouer sur les concentrations respectives de chacune des phases de la composition distribuée, il est possible au moyen d'un même dispositif de distribuer une multitude de compositions différentes.The composition according to the invention consists of at least two phases which do not are not permanently miscible. For example, there may be two immiscible oily phases of different density, of an oily phase and an aqueous phase or an oily phase and a phase hydroalcoholic. So because of the density difference between the two immiscible phases, the heavy phase will deposit in the bottom of the container, while the light phase will float above the heavy phase. The phase separation is done more or less quickly depending on the density difference between the two phases. By shaking the contents of the container, a more or less homogeneous "mixture" of the two phases is formed under form of a dispersion, suspension or emulsion. Leaving rest the assembly, the phases "mix" or separate under the effect of their density differences. Depending on the position of the container, it is possible to distribute either one of the phases or the other, or a mixture of of them. By being able to play on the respective concentrations of each phases of the distributed composition, it is possible by means of a same device for distributing a multitude of different compositions.

Par exemple, on peut ainsi distribuer une eau de parfum dont la force et les notes peuvent être choisies à volonté. L'utilisatrice dispose ainsi à l'intérieur du même conditionnement, d'une eau de parfum pour le matin, et d'une eau de parfum pour le soir, avec la possibilité de passer de façon évolutive de la première à la seconde, en permettant, par une agitation plus ou moins forte et plus ou moins longue de l'ensemble, toute combinaison à rapport de concentrations variable, formée à partir des deux eaux de parfum .For example, one can thus distribute an eau de parfum whose strength and notes can be chosen at will. The user thus has inside the same packaging, one eau de parfum for the morning, and one eau de fragrance for the evening, with the possibility of changing from the first to second, allowing, by more or less strong agitation and more or less long of the whole, any combination with ratio of variable concentrations, formed from two perfumes.

Il est possible également de distribuer une composition de coloration ou de maquillage dont les teintes et nuances peuvent être choisies à volonté.It is also possible to distribute a coloring composition or make-up whose colors and shades can be chosen at will.

Selon un autre aspect intéressant de l'invention, il est possible d'avoir une première phase (eau de parfum, eau de toilette, composition hydratante) formant la phase principale de la composition, à savoir celle qui est appliquée principalement, voire en routine, et une phase secondaire (contenant des filtres solaires, des adoucissants, des cicatrisants, des agents apaisants, des huiles essentielles) que l'utilisatrice peut, si elle le souhaite, utiliser seule, ou en combinaison avec la phase principale de manière modifier les caractéristiques de cette dernière ou à lui rajouter des propriétés. La teneur en phase secondaire de la concentration distribuée dépend dans une large mesure du degré d'agitation de l'ensemble avant application.According to another interesting aspect of the invention, it is possible to have a first phase (eau de parfum, eau de toilette, moisturizing composition) forming the main phase of the composition, namely that which is applied mainly, even routinely, and a secondary phase (containing filters sunscreen, softeners, healing agents, soothing agents, oils essential) that the user can, if she wishes, use alone, or in combination with the main phase in order to modify the characteristics of the latter or to add properties to it. The phase content secondary to the distributed concentration depends to a large extent on the degree of agitation of the assembly before application.

Selon l'invention la composition peut comprendre deux phases liquides. A titre d'exemple, il s'agit d'une première phase alcoolique ou hydro-alcoolique (eau de parfum) et d'une seconde phase huileuse (produit de soin adoucissant, apaisant, etc.). Le liquide peut également être sous forme d'un gel ou d'une émulsion (phase hydrocarbure). Comme on le verra plus en détail par la suite, la composition utilisée dans l'ensemble selon l'invention peut comprendre une phase liquide et une phase particulaire, notamment solide. Les particules peuvent être plus lourdes ou plus légères que la phase liquide.According to the invention, the composition can comprise two liquid phases. As example, it is a first alcoholic or hydro-alcoholic phase (water perfume) and a second oily phase (softening care product, soothing, etc.). The liquid can also be in the form of a gel or a emulsion (hydrocarbon phase). As we will see in more detail later, the composition used as a whole according to the invention can comprise a liquid phase and a particulate phase, in particular solid. The particles may be heavier or lighter than the liquid phase.

Dans le cas d'une composition formée à 50% d'une première phase liquide, et à 50% d'une seconde phase liquide, en disposant l'ensemble dans une première position (par exemple tête en haut), on distribue la phase en communication avec la pompe (la phase légère dans le cas d'une pompe sans tube plongeur, et la phase lourde dans le cas d'une pompe avec tube plongeur). En retournant le récipient (tête en bas), on distribue la phase lourde dans le cas d'une pompe sans tube plongeur et la phase légère dans le cas d'une pompe avec tube plongeur. En agitant le contenu du récipient, de manière à former un mélange plus ou moins homogène des deux phases, on distribue un mélange formé en partie de chacune des phases, les concentrations respectives de chacune des phases dépendant dans une large mesure du degré d'agitation et de la position de distribution (tête en haut ou tête en bas).In the case of a composition formed at 50% of a first liquid phase, and at 50% of a second liquid phase, by placing the assembly in a first position (for example head up), the phase is distributed in communication with the pump (the light phase in the case of a pump without dip tube, and the heavy phase in the case of a pump with tube diver). By turning the container upside down, the heavy phase is distributed in the case of a pump without dip tube and the light phase in the case of a pump with dip tube. By shaking the contents of the container, so as to form a more or less homogeneous mixture of the two phases, we distributes a mixture formed in part of each of the phases, the respective concentrations of each of the dependent phases to a large extent measurement of the degree of agitation and of the distribution position (head up or upside down).

Dans le cas d'une phase particulaire dans une phase liquide, il est possible de distribuer soit la phase liquide seule, soit la phase liquide en combinaison avec la phase particulaire, la concentration en particules de la composition distribuée dépendant notamment du degré d'agitation.In the case of a particulate phase in a liquid phase, it is possible to distribute either the liquid phase alone or the liquid phase in combination with the particulate phase, the particle concentration of the composition distributed depending in particular on the degree of agitation.

Selon un mode de réalisation préférentiel, le récipient peut être formé d'une poche à parois souples. Une telle poche peut être formée d'une ou plusieurs couches de matériaux thermoplastiques (polyéthylène, polypropylènes, PET) et/ou métalliques (aluminium). L'épaisseur des parois doit être suffisamment faible pour leur permettre de se contracter et de s'affaisser sur elles mêmes, sous l'effet de la dépression résultant de la perte de volume de produit sans remplacement par un volume d'air correspondant. La section du récipient peut être de n'importe quelle forme : carrée, ovale, circulaire, elliptique, octogonale, etc..According to a preferred embodiment, the container can be formed of a pocket with flexible walls. Such a pocket can be formed from one or more layers of thermoplastic materials (polyethylene, polypropylenes, PET) and / or metallic (aluminum). Wall thickness must be sufficient weak to allow them to contract and collapse on themselves, under the effect of depression resulting from the loss of volume of product without replacement with a corresponding air volume. The container section can be of any shape: square, oval, circular, elliptical, octagonal, etc.

Ce mode de réalisation est tout particulièrement avantageux en ce qu'il offre une souplesse de fonctionnement sans comparaison avec celle de modes de réalisation différents, notamment du type à piston, auxquels il sera fait référence par la suite. En outre, la poche à parois souples permet d'utiliser des phases très liquides, ce qui serait difficilement réalisable avec un dispositif à piston.This embodiment is particularly advantageous in that it offers flexibility of operation without comparison with that of different embodiments, in particular of the piston type, which will be made reference later. In addition, the flexible wall pocket allows the use of very liquid phases, which would be difficult to achieve with a device with piston.

De préférence, la poche à parois souples est disposée à l'intérieur d'une enceinte rigide. Cette enceinte rigide assure une bonne tenue du récipient, notamment en position debout, même lorsque le récipient est pratiquement vide. De préférence, un orifice de reprise d'air est prévu, notamment dans le fond de l'enceinte, pour permettre l'entrée d'air dans le volume situé entre l'enceinte rigide et la poche souple, lorsque cette dernière diminue de volume, après chaque distribution.Preferably, the pocket with flexible walls is disposed inside a rigid enclosure. This rigid enclosure ensures good behavior of the container, especially when standing, even when the container is practically empty. Preferably, an air intake orifice is provided, in particular in the bottom of the enclosure, to allow air to enter the volume between the rigid enclosure and the flexible pocket, when the latter decreases in volume, after each distribution.

Des moyens peuvent être prévus pour, lorsque les parois de la poche s'affaissent sur elles mêmes au fur et à mesure de la vidange du récipient, prévenir l'obturation d'un passage d'entrée de ladite pompe. Dans le cas d'une pompe sans tube plongeur, on utilise soit une grille ondulée disposée à l'intérieur du récipient, soit des embossages réalisés sur les parois du récipient souple, et qui sont aptes, lorsque les faces de la poche sont plaquées l'une sur l'autre, en fin d'utilisation du contenu du récipient, à définir des canaux permettant l'acheminement du produit vers la pompe. D'autres moyens encore peuvent être utilisés.Means may be provided for, when the walls of the pocket collapse on themselves as the container is emptied, prevent blockage of an inlet passage of said pump. In the case of a pump without dip tube, we use either a corrugated grid arranged at the inside of the container, i.e. embossments made on the walls of the container flexible, and which are suitable, when the faces of the pocket are pressed one on the other, at the end of use of the contents of the container, to define channels allowing the delivery of the product to the pump. Other ways can be used.

Alternativement, le récipient est constitué d'un tube souple, d'un flacon à parois formant soufflet, d'un flacon soufflé ou coextrudé à parois fines, d'un récipient à membrane, notamment élastique, ou d'un flacon à l'intérieur duquel est disposé un piston suiveur.Alternatively, the container consists of a flexible tube, a walled bottle forming a bellows, of a blown or coextruded bottle with thin walls, of a container for membrane, in particular elastic, or of a bottle inside which is disposed a follower piston.

La solution consistant à utiliser un récipient équipé d'un piston suiveur n'est toutefois pas préférée, notamment quand il s'agit d'utiliser une ou plusieurs phases très liquides, et ce, principalement pour des raisons d'étanchéité. Pour plus d'étanchéité, il faut alors serrer davantage le piston contre la surface interne du récipient, lequel serrage s'effectue au détriment de la souplesse de fonctionnement. En outre, en agitant vigoureusement le récipient en vue de distribuer un mélange de deux phases contenues dans le récipient, le piston risque de reculer dans le corps du récipient, ce qui peut perturber la distribution. The solution of using a container fitted with a follower piston is not however not preferred, especially when it comes to using one or more very liquid phases, mainly for sealing reasons. For more tightness, it is then necessary to tighten more the piston against the surface internal container, which tightening takes place at the expense of flexibility operation. In addition, by vigorously shaking the container in order to distribute a mixture of two phases contained in the container, the piston risk of falling back into the container body, which could disturb the distribution.

La pompe peut être montée sur le récipient, ou sur une pièce de montage intermédiaire, notamment par sertissage, vissage, ou montage à force.The pump can be mounted on the container, or on a mounting part intermediate, in particular by crimping, screwing, or mounting by force.

La pompe peut être alimentée depuis le fond du récipient au moyen d'un tube plongeur dont une extrémité libre descend sensiblement jusqu'au fond du récipient. Ainsi, dans le cas d'une composition à deux phases liquides, en position tête en haut, la pompe est alimentée en phase lourde via le tube plongeur. En position tête en bas, la pompe est alimentée en phase légère via le tube plongeur. De préférence toutefois, la pompe est alimentée directement, c'est à dire sans tube plongeur.The pump can be supplied from the bottom of the container by means of a tube plunger, one free end of which descends substantially to the bottom of the container. Thus, in the case of a composition with two liquid phases, in head up position, the pump is supplied in heavy phase via the tube diver. In head down position, the pump is supplied in light phase via the dip tube. Preferably, however, the pump is supplied directly, ie without dip tube.

De préférence, la pompe est surmontée d'un bouton poussoir, comportant ou non des moyens de diffusion, notamment sous forme d'une buse. D'autres moyens de diffusion peuvent être utilisés. A titre d'exemple, on peut citer une grille, un fritté, un embout applicateur, etc.Preferably, the pump is surmounted by a push button, comprising or not diffusion means, in particular in the form of a nozzle. Others means of dissemination may be used. As an example, we can cite a grid, frit, applicator tip, etc.

Selon un mode de réalisation avantageux, la composition comporte une phase liquide et une phase particulaire, notamment solide, de densité différente de celle du liquide. Les particules peuvent être plus lourdes ou plus légères que la phase liquide. De telles particules peuvent être sous forme d'une poudre, de microcapsules ou de nanocapsules, de pigments, de charges, de nacres, ou de talc.According to an advantageous embodiment, the composition comprises a phase liquid and a particulate phase, in particular solid, of density different from that of the liquid. Particles may be heavier or lighter than liquid phase. Such particles can be in the form of a powder, microcapsules or nanocapsules, pigments, fillers, nacres, or talc.

A titre d'exemple de composition liquide-solide, on peut citer une eau de parfum dans laquelle sont disposées de microcapsules contenant ledit parfum (ou un autre parfum) sous forme d'huiles essentielles. Les parois de telles microcapsules peuvent être formées de composés phénoliques, d'alginate, de gélatine, ou de cyanoacrylate.As an example of a liquid-solid composition, there may be mentioned an eau de parfum in which microcapsules containing said perfume (or a other perfume) in the form of essential oils. The walls of such microcapsules can be formed from phenolic compounds, alginate, gelatin, or cyanoacrylate.

A titre d'exemple, dans un récipient de 50 ml on dispose 5g de telles micro capsules. Le récipient est complété avec la phase liquide, constituée dudit parfum. Les particules sont plus lourdes que le liquide, et se déposent au fond du récipient. La pompe est sans tube plongeur. En tenant le dispositif tête en haut, on pulvérise uniquement du parfum. En agitant le récipient, les microcapsules se mettent en suspension dans la phase liquide, avec laquelle elles sont distribuées. La concentration en microcapsules dépend dans une large mesure du degré d'agitation du récipient. Le produit contenu dans les micro capsules est libéré, soit lors de leur passage dans la pompe, à l'intérieur de laquelle elles sont "broyées", soit après dépôt sur la peau, en massant légèrement la peau après pulvérisation.For example, in a 50 ml container there are 5 g of such micro capsules. The container is completed with the liquid phase, consisting of said perfume. Particles are heavier than liquid, and settle on the bottom of the container. The pump is without dip tube. Holding the device head in high, we only spray perfume. By shaking the container, the microcapsules are suspended in the liquid phase, with which they are distributed. The concentration of microcapsules depends in a large measure of the degree of agitation of the container. The product contained in micro capsules are released, either when they pass through the pump, inside from which they are "crushed", either after being deposited on the skin, by massaging slightly the skin after spraying.

A titre indicatif, la phase particulaire représente en volume 0,5 à 30 % du volume total de la composition, et de préférence, 1 à 10% du volume total de la composition.As an indication, the particulate phase represents in volume 0.5 to 30% of the total volume of the composition, and preferably 1 to 10% of the total volume of the composition.

Selon une autre forme de réalisation, ladite composition comprend deux phases liquides non-miscibles, et de densités différentes. A titre d'exemple, il peut s'agir notamment d'une phase aqueuse ou hydro-alcoolique et d'une phase huileuse.According to another embodiment, said composition comprises two immiscible liquid phases, and of different densities. For example, there may in particular be an aqueous or hydro-alcoholic phase and a oily phase.

Des moyens, notamment une bille, peuvent être prévus de manière à permettre d'agiter le contenu du récipient. Ces moyens d'agitation peuvent être très avantageux dans le cas de deux phases très difficiles à mélanger.Means, in particular a ball, can be provided so as to allow shake the contents of the container. These means of agitation can be very advantageous in the case of two very difficult phases to mix.

L'invention concerne également l'utilisation d'un récipient à volume variable surmonté d'une pompe sans reprise d'air pour la distribution d'une composition selon un rapport de concentrations variable des n phases (n≥2) constituant ladite composition, l'une au moins des phases étant liquide, lesdites phases étant non miscibles entre elles et présentant des densités différentes.The invention also relates to the use of a container with variable volume surmounted by a pump without air intake for the distribution of a composition according to a variable concentration ratio of the n phases (n≥2) constituting said composition, at least one of the phases being liquid, said phases being immiscible with one another and having different densities.

Le rapport des concentrations respectives de chacune des phases varie dans une plage très large. A l'une des extrémités de la plage, la composition distribuée peut être formée à 100% de la phase légère. A l'autre extrémité de la plage, la composition de distribution peut être formée à 100% de la phase lourde. Entre les deux, les possibilités sont innombrables, et choisies à volonté, en jouant notamment sur le degré d'agitation avant application.The ratio of the respective concentrations of each phase varies in a very wide range. At one end of the range, the composition distributed can be formed at 100% of the light phase. At the other end of the range, the distribution composition can be formed at 100% of the phase heavy. Between the two, the possibilities are endless, and chosen at will, playing in particular on the degree of agitation before application.

Dans le cas d'une composition à trois phases, dont notamment deux liquides, il est possible de distribuer sélectivement une première phase (légère), ou une seconde phase (lourde), ou un mélange des première et seconde phase avec une troisième phase de densité intermédiaire entre les densités des première et seconde phases.In the case of a composition with three phases, including in particular two liquids, it is possible to selectively distribute a first phase (light), or a second phase (heavy), or a mixture of the first and second phase with a third density phase intermediate between the densities of the first and second phases.

Selon un autre aspect de l'invention, on réalise également un procédé de distribution, au moyen d'un récipient à volume variable sur lequel est montée une pompe opérant sans reprise d'air, d'une composition formée d'au moins deux phases A, B non miscibles entre elles et ayant des densités différentes, l'une au moins des phases étant liquide, ledit procédé consistant à sélectivement :

  • a) disposer le récipient dans une première position de manière à, après séparation des phases sous l'effet de leurs différences de densité, avoir l'une des phases A en communication avec un passage d'entrée de la pompe, puis, actionner la pompe de manière à distribuer une composition formée essentiellement de la phase A;
  • b) agiter le contenu du récipient de manière à réaliser un mélange temporaire des deux phases, puis, actionner la pompe de manière à distribuer une composition formée en partie de chacune des phases A et B, le rapport des concentrations des phases A/B dépendant notamment du degré d'agitation.
    • According to another aspect of the invention, a distribution process is also carried out, by means of a variable-volume container on which is mounted a pump operating without air intake, of a composition formed from at least two phases A, B immiscible with one another and having different densities, at least one of the phases being liquid, said process consisting in selectively:
  • a) place the container in a first position so that, after separation of the phases under the effect of their differences in density, have one of the phases A in communication with an inlet passage of the pump, then, activate the pump so as to distribute a composition formed essentially from phase A;
  • b) shake the contents of the container so as to temporarily mix the two phases, then activate the pump so as to distribute a composition formed in part from each of phases A and B, the ratio of the concentrations of phases A / B depending including the degree of agitation.

    • De préférence, dans le cas d'une composition comprenant une première phase liquide et une seconde phase liquide, la seconde phase liquide représente en volume 2 à 50% du volume total de la composition, et de préférence encore, 5 à 30% du volume total de la composition.Preferably, in the case of a composition comprising a first phase liquid and a second liquid phase, the second liquid phase represents in volume 2 to 50% of the total volume of the composition, and more preferably 5 to 30% of the total volume of the composition.

    Avantageusement, le procédé consiste sélectivement en outre à :
       b) disposer le récipient dans une seconde position de manière à, après séparation des phases sous l'effet de leurs différences de densité, avoir l'autre des phases B en communication avec ledit passage d'entrée de la pompe, puis, actionner la pompe de manière à distribuer une composition formée essentiellement de la phase B.    Advantageously, the method also selectively consists in:
    b) place the container in a second position so that, after separation of the phases under the effect of their differences in density, have the other of the B phases in communication with said pump inlet passage, then actuate the pump so as to distribute a composition formed essentially from phase B.

    Dans cette dernière version du procédé, il est possible de distribuer séparément soit la première phase, soit la seconde, soit un mélange des deux phases. Cette version est particulièrement adaptée à la distribution de deux phases liquides.In this latest version of the process, it is possible to distribute separately either the first phase or the second, or a mixture of the two phases. This version is particularly suitable for the distribution of two liquid phases.

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

    • les figures 1A-1C illustrent un premier mode de réalisation de l'ensemble selon l'invention, et
    • les figures 2A-2B illustrent un second mode de réalisation de l'ensemble selon l'invention.
    The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
    • FIGS. 1A-1C illustrate a first embodiment of the assembly according to the invention, and
    • Figures 2A-2B illustrate a second embodiment of the assembly according to the invention.

    Dans le mode de réalisation illustré aux figures 1A-1C, l'ensemble 1 selon l'invention comprend une poche à parois souples 2 (formée d'un complexe multi-couches comportant une couche d'aluminium) dont une extrémité est fermée par un fond 3 et dont l'autre extrémité présente un bord libre délimitant une ouverture 4. Sur ladite ouverture 4 est montée de manière étanche une pièce intermédiaire 5. Le montage étanche de la pièce intermédiaire 5 sur la poche est réalisé par collage ou soudure entre la surface intérieure du bord libre de la poche et la surface externe d'une jupe 6 portée par la pièce intermédiaire 5. La pièce intermédiaire 5 comporte une jupe latérale 7 comportant une gorge annulaire 8 apte à coopérer par claquage avec un cordon correspondant 9 formé sur la surface externe d'une enceinte rigide 10 en polypropylène. Le fond de l'enceinte 10 est pourvu d'un trou 11 permettant une entrée d'air dans le volume compris entre l'enceinte rigide 10 et la poche à parois souples 2, permettant ainsi de compenser la diminution de volume de la poche résultant de la distribution d'une dose de produit.In the embodiment illustrated in FIGS. 1A-1C, the assembly 1 according to the invention comprises a pocket with flexible walls 2 (formed of a complex multi-layer with an aluminum layer) one end of which is closed by a bottom 3 and the other end of which has a free edge delimiting an opening 4. On said opening 4 is sealingly mounted a intermediate piece 5. The sealed mounting of the intermediate piece 5 on the pocket is made by gluing or welding between the inner surface of the edge free of the pocket and the external surface of a skirt 6 carried by the workpiece intermediate 5. The intermediate piece 5 has a side skirt 7 comprising an annular groove 8 capable of cooperating by breakdown with a corresponding cord 9 formed on the external surface of a rigid enclosure 10 polypropylene. The bottom of the enclosure 10 is provided with a hole 11 allowing an air inlet in the volume between the rigid enclosure 10 and the bag flexible walls 2, thus making it possible to compensate for the reduction in volume of the pocket resulting from the distribution of a dose of product.

    La pièce intermédiaire 5, comprend, à l'opposé des jupes 6 et 8, une cheminée axiale 12 dans laquelle est montée à force une pompe opérant sans reprise d'air 13. La pompe comporte une tige émergente 14 sur laquelle est monté un bouton poussoir 15 comportant un canal 16 reliant la tige émergente 14 à une buse tourbillonnaire 17, formant un organe de diffusion de la composition à distribuer.The intermediate part 5, comprises, opposite the skirts 6 and 8, a chimney axial 12 in which a pump operating without recovery is forcibly mounted air 13. The pump comprises an emerging rod 14 on which is mounted a push button 15 comprising a channel 16 connecting the emerging rod 14 to a vortex nozzle 17, forming a member for diffusing the composition to distribute.

    A l'opposé de la cheminée axiale 12, la pièce intermédiaire 5 se prolonge à l'intérieur du récipient souple 2 par une pluralité de barrettes 18 espacées régulièrement, et formant une structure "anti-prisonnier" apte à empêcher l'obturation d'un passage d'entrée 19 de la pompe 13, par les parois souples de la poche 2, lorsque celles-ci s'affaissent sur elles-mêmes, au fil de la distribution du contenu de la poche 2. A l'intérieur de la poche est disposée une bille 20, apte à faciliter le mélange de la composition contenue dans la poche souple 2.Opposite the axial chimney 12, the intermediate piece 5 extends to the interior of the flexible container 2 by a plurality of spaced bars 18 regularly, and forming an "anti-prisoner" structure capable of preventing the closure of an inlet passage 19 of the pump 13, by the flexible walls of pocket 2, when these collapse on themselves, over the distribution of the contents of the pocket 2. Inside the pocket is disposed a ball 20, capable of facilitating the mixing of the composition contained in the pocket flexible 2.

    La composition contenue dans la poche 2 est constituée d'une phase principale A, constituée d'un parfum dans une phase hydroalcoolique à faible teneur en eau (moins de 15%) et d'une phase secondaire B formée d'une huile siliconée contenant notamment un agent apaisant tel que de l'allantoïne et un filtre solaire. La phase secondaire constitue environ 20% en volume de la composition totale, et est plus lourde que la phase hydroalcoolique.The composition contained in pocket 2 consists of a main phase A, consisting of a perfume in a hydroalcoholic phase with a low content water (less than 15%) and a secondary phase B formed of a silicone oil containing in particular a soothing agent such as allantoin and a filter solar. The secondary phase constitutes approximately 20% by volume of the total composition, and is heavier than the hydroalcoholic phase.

    Lorsque l'ensemble 1 se trouve tête en haut, comme représenté à la figure 1A, le parfum est en haut (phase A), l'huile siliconée est en bas (phase B). Dans cette position représentée à la figure 1A, en appuyant sur le bouton poussoir 15, l'utilisatrice pulvérise du parfum (phase A) à l'endroit souhaité, via la buse 17. When the assembly 1 is head up, as shown in FIG. 1A, the fragrance is at the top (phase A), the silicone oil is at the bottom (phase B). In this position shown in Figure 1A, by pressing the push button 15, the user sprays perfume (phase A) at the desired location, via the nozzle 17.

    En retournant l'ensemble 1 dans la position représentée à la figure 1B, l'huile siliconée (phase B) est mise en communication avec la pompe 13, et peut être pulvérisée à l'endroit souhaité. On dépose ainsi sur la peau, notamment à l'endroit ayant fait l'objet d'une pulvérisation préalable de parfum, une composition, légèrement grasse, dont la finalité est d'apaiser le "feu" de l'alcool contenu dans le parfum, et en outre, de protéger la peau contre les rayonnements UV. La peau peut être massée légèrement de manière à étaler le produit appliqué et à en favoriser la pénétration.By returning the assembly 1 to the position shown in Figure 1B, the oil silicone (phase B) is put in communication with the pump 13, and can be sprayed at the desired location. It is thus deposited on the skin, in particular at the place having been the subject of a prior spraying of perfume, a composition, slightly oily, the purpose of which is to appease the "fire" of alcohol contained in the fragrance, and in addition, to protect the skin against UV radiation. The skin can be massaged lightly so as to spread the product applied and to promote its penetration.

    En agitant l'ensemble, de la manière représentée à la figure 1C, les deux phases se mélangent de façon plus ou moins homogène. Il est alors possible de pulvériser, en position tête en haut, ou tête en bas, un mélange des phases A et B, ayant à la fois des vertus parfumantes, apaisantes, et de protection solaire. En reposant l'ensemble, les deux phases se "démélangent" et reprennent leurs positions respectives de la figure 1A.By shaking the assembly, as shown in FIG. 1C, the two phases mix more or less homogeneously. It is then possible spraying, in head-up or head-down position, a mixture of the phases A and B, having both fragrant, soothing and protective properties solar. By resting the assembly, the two phases "mix" and return to their respective positions in FIG. 1A.

    Dans le mode de réalisation des figures 2A-2B, l'ensemble 1 comprend un flacon 50 en matériau thermoplastique, de forme cylindrique, et surmonté d'un goulot 51 à l'intérieur duquel est montée en force une pompe sans reprise d'air 13. La pompe est surmontée d'un bouton poussoir 15 comportant un moyen de diffusion sous forme d'une buse tourbillonnaire 17. Le fond du flacon 50 est ouvert. A l'intérieur du flacon 50, est monté de manière étanche, mais libre en coulisse, un piston suiveur 52 qui, au fur et à mesure de la distribution du produit, remonte dans le flacon 50, sous l'effet de la dépression résultant de la diminution du volume de produit, laquelle diminution n'est pas compensée par un volume d'air correspondant. Alternativement, le fond du flacon peut être obturé par un fond rapporté comprenant un orifice de reprise d'air.In the embodiment of FIGS. 2A-2B, the assembly 1 comprises a bottle 50 in thermoplastic material, cylindrical in shape, and surmounted by neck 51 inside which a pump is forcibly mounted without air intake 13. The pump is surmounted by a push button 15 comprising a means of diffusion in the form of a vortex nozzle 17. The bottom of the bottle 50 is open. Inside the bottle 50, is mounted in a sealed manner, but free in slides, a follower piston 52 which, as the distribution of the product, rises in the bottle 50, under the effect of the depression resulting from the decrease in product volume, which decrease is not offset by a corresponding volume of air. Alternatively, the bottom of the bottle can be closed by an attached bottom comprising an air intake orifice.

    A l'intérieur du flacon de 50 ml, on dispose 5g de microcapsules B, emprisonnant un parfum sous forme d'huiles essentielles. On remplit le flacon au moyen d'une eau de toilette A, en phase hydroalcoolique. Les microcapsules sont de densité plus importante que l'eau de toilette, et dans la position représentée à la figure 2A, se déposent au fond du flacon 50. Dans cette position, en appuyant sur le bouton poussoir, l'utilisatrice pulvérise essentiellement (au moins environ 85%, en fonction du temps laissé aux phases pour se séparer par leurs différences de densité) de l'eau de toilette à l'endroit désiré, via la buse 17.Inside the 50 ml bottle, there are 5 g of microcapsules B, trapping a perfume in the form of essential oils. We fill the bottle by means of eau de toilette A, in the hydroalcoholic phase. The microcapsules are more dense than toilet water, and in the position shown in Figure 2A, are deposited at the bottom of the bottle 50. In this position, by pressing the push button, the user sprays essentially (at least about 85%, depending on the time left for phases to separate by their density differences) from the toilet water to the desired location, via nozzle 17.

    Lorsque l'utilisatrice souhaite modifier la note de son eau de toilette, ou lui donner plus de force, elle agite le flacon. Ce faisant, en fonction de la force d'agitation, elle met plus ou moins de microcapsules en suspension dans l'eau de toilette, de la manière représentée à la figure 2B. En actionnant le bouton poussoir, une partie des microcapsules va être aspirée par la pompe et pulvérisée avec l'eau de toilette. Les microcapsules pourront être "broyées" en passant dans la pompe, ce qui va produire la libération des huiles essentielles. Alternativement, la libération des huiles essentielles se fait après application du mélange sur la peau, en massant légèrement cette dernière. En reposant l'ensemble, les microcapsules se déposent au fond du flacon, et reprennent leur position de la figure 2A.When the user wishes to change the rating of her eau de toilette, or give more strength, she shakes the bottle. Doing so, depending on the strength of agitation, it puts more or less microcapsules in suspension in water toilet, as shown in Figure 2B. By pressing the button pusher, part of the microcapsules will be sucked by the pump and sprayed with toilet water. The microcapsules can be "crushed" by passing through the pump, which will release essential oils. Alternatively, the release of essential oils is done after application of mixture on the skin, gently massaging the latter. Resting all, the microcapsules are deposited at the bottom of the bottle, and resume their position in FIG. 2A.
