CAPSULE DE FABRICATION D'UN PRODUIT COSMETIQUE ET CAPSULE FOR MANUFACTURING A COSMETIC PRODUCT AND
METHODE DE FABRICATION D'UN PRODUIT COSMETIQUE A METHOD OF MANUFACTURING A COSMETIC PRODUCT
PARTIR D'UNE TELLE CAPSULE  FROM SUCH A CAPSULE
DOMAINE DE L'INVENTION FIELD OF THE INVENTION
L'invention concerne une capsule, à usage unique, de fabrication d'un produit cosmétique, ainsi qu'une méthode de fabrication, par le consommateur final, d'un produit cosmétique directement consommable par le consommateur final, à partir d'une telle capsule. The invention relates to a single-use capsule for the manufacture of a cosmetic product, and to a method for the manufacture by the end consumer of a cosmetic product which can be consumed directly by the final consumer, on the basis of such a product. capsule.
CONTEXTE DE L'INVENTION L'invention concerne une capsule, à usage unique, de fabrication d'un produit cosmétique, ainsi qu'une méthode de fabrication, par le consommateur final, d'un produit cosmétique directement consommable par le consommateur final et permet la fabrication d'une dose limitée de produit cosmétique dont la composition est alors facilement personnalisable en fonction des ingrédients de départ. Pour utiliser un produit cosmétique distinct à la prochaine application, le consommateur final n'a besoin que de changer de capsule. BACKGROUND OF THE INVENTION The invention relates to a single-use capsule for the manufacture of a cosmetic product, as well as to a method of manufacturing, by the end user, of a cosmetic product that can be consumed directly by the end consumer and allows the manufacture of a limited dose of cosmetic product whose composition is then easily customizable according to the starting ingredients. To use a separate cosmetic product for the next application, the end consumer only needs to change caps.
De plus, le produit cosmétique obtenu est immédiatement consommable par le consommateur final, ce qui d'une part permet une meilleure fraîcheur du produit cosmétique et d'autre part dispense de la plupart voire de tous les conservateurs habituellement utilisés.  In addition, the cosmetic product obtained is immediately consumable by the end consumer, which on the one hand allows a better freshness of the cosmetic product and on the other hand exempts most or all of the usual preservatives used.
L'invention concerne une capsule, à usage unique, de fabrication d'un produit cosmétique, ainsi qu'une méthode de fabrication, par le consommateur final, d'un produit cosmétique directement consommable par le consommateur final, à partir d'une telle capsule, sans l'utilisation d'une quelconque machine chargée de réaliser le transfert d'un compartiment à l'autre. Ce transfert d'un compartiment à l'autre du mélange est réalisé par le consommateur final du produit cosmétique, par simple pression de la main. La pression d'une main est substantiellement plus faible que la pression exercée par les éléments d'une telle machine. La fabrication du produit cosmétique, ne nécessitant pas de machine, c'est-à-dire pas de dispositif actif utilisant une source d'énergie, mais seulement l'énergie manuelle du consommateur final, est alors nettement plus simple et moins coûteuse. The invention relates to a single-use capsule for the manufacture of a cosmetic product, and to a method for the manufacture by the end consumer of a cosmetic product which can be consumed directly by the final consumer, on the basis of such a product. capsule, without the use of any machine responsible for performing the transfer of a compartment to the other. This transfer from one compartment to another of the mixture is carried out by the final consumer of the cosmetic product, by simple hand pressure. The pressure of a hand is substantially lower than the pressure exerted by the elements of such a machine. The manufacture of the cosmetic product, not requiring a machine, that is to say no active device using a power source, but only the manual energy of the final consumer, is then much simpler and less expensive.
Selon un premier art antérieur, par exemple décrit dans le brevet US4458811, il est connu une capsule à deux compartiments de fabrication d'un produit cosmétique par mélange du contenu d'un compartiment dans l'autre compartiment. Une mise en communication des deux compartiments permet le mélange. La mise en communication une fois effectuée, le passage entre les compartiments est très large. Le mélange est réalisé en secouant l'ensemble de la capsule. L'homogénéisation du produit cosmétique obtenu est insuffisante. De plus, cette homogénéisation peu performante ne permet pas de réaliser des galéniques de type émulsion avec une telle capsule à deux compartiments séparant respectivement la phase grasse et la phase aqueuse.  According to a first prior art, for example described in patent US4458811, it is known a capsule with two compartments for manufacturing a cosmetic product by mixing the contents of one compartment in the other compartment. A communication between the two compartments allows mixing. The setting in communication once carried out, the passage between the compartments is very broad. The mixture is made by shaking the entire capsule. The homogenization of the cosmetic product obtained is insufficient. In addition, this poorly performing homogenization does not make it possible to produce emulsion-type galenics with such a two-compartment capsule respectively separating the fatty phase and the aqueous phase.
Selon un deuxième art antérieur, par exemple décrit dans le brevet According to a second prior art, for example described in the patent
DE3724921, il est connu une capsule à trois compartiments de fabrication d'un produit cosmétique par mélange du contenu de deux compartiments dans un troisième compartiment faisant office de chambre mélange. Une mise en communication des différents compartiments permet le mélange. L'homogénéisation du produit cosmétique obtenu est insuffisante. Par ailleurs, la structure globale de la capsule est relativement complexe. De plus, cette homogénéisation peu performante ne permet pas de réaliser des galéniques de type émulsion avec une telle capsule à deux compartiments séparant respectivement la phase grasse et la phase aqueuse. RESUME DE L'INVENTION DE3724921, it is known a capsule with three compartments for manufacturing a cosmetic product by mixing the contents of two compartments in a third compartment acting as a mixing chamber. Communicating the different compartments allows mixing. The homogenization of the cosmetic product obtained is insufficient. Moreover, the overall structure of the capsule is relatively complex. In addition, this poorly performing homogenization does not make it possible to produce emulsion-type galenics with such a two-compartment capsule respectively separating the fatty phase and the aqueous phase. SUMMARY OF THE INVENTION
Le but de la présente invention est de fournir une capsule de fabrication d'un produit cosmétique palliant au moins partiellement les inconvénients précités. The object of the present invention is to provide a capsule for manufacturing a cosmetic product at least partially overcomes the aforementioned drawbacks.
Plus particulièrement, l'invention vise à fournir une capsule, à usage unique, de fabrication d'un produit cosmétique, directement consommable par le consommateur final, pour laquelle le mélange obtenu soit mieux homogénéisé. Pour cela le passage entre les compartiments de la capsule comprend un rétrécissement en particulier suffisamment étroit pour opérer un cisaillement du mélange en sortant de ce rétrécissement lors de son transfert d'un compartiment de la capsule dans l'autre compartiment de la capsule.  More particularly, the invention aims to provide a capsule, for single use, manufacturing a cosmetic product, directly consumable by the end consumer, for which the mixture obtained is better homogenized. For this, the passage between the compartments of the capsule comprises a narrowing in particular narrow enough to effect a shear of the mixture exiting the narrowing during its transfer from one compartment of the capsule into the other compartment of the capsule.
Avantageusement la capsule est de structure simple ou simplifiée et son utilisation pour obtenir le produit cosmétique directement consommable par le consommateur final est facile ou facilitée. Les parties essentielles de la capsule sont alors avantageusement les deux compartiments reliés entre eux par un rétrécissement réalisant le cisaillement du mélange sortant de ce rétrécissement.  Advantageously, the capsule is of simple or simplified structure and its use to obtain the cosmetic product directly consumable by the end user is easy or facilitated. The essential parts of the capsule are then advantageously the two compartments interconnected by a narrowing effect shearing the mixture coming out of this narrowing.
A cette fin, la présente invention propose une capsule, à usage unique, de fabrication d'un produit cosmétique, comprenant : au moins un premier compartiment de conditionnement déformable comprenant une quantité prédéterminée d'une première phase d'un produit cosmétique, au moins un deuxième compartiment de conditionnement déformable comprenant une quantité prédéterminée d'une deuxième phase d'un produit cosmétique, lesdites première et deuxième phases étant différentes entre elles, un passage fermé reliant lesdits compartiments de conditionnement entre eux, ledit passage étant étanche par rapport à l'extérieur desdits compartiments de conditionnement, lesdits compartiments de conditionnement étant suffisamment souples, la paroi externe dudit passage étant suffisamment solide et la fermeture dudit passage étant suffisamment fragile, pour qu'une pression mécanique exercée par une main puisse ouvrir ledit passage en conservant l'étanchéité dudit passage par rapport à l'extérieur desdits compartiments de conditionnement, ledit passage, une fois ouvert, comprenant un rétrécissement entre lesdits compartiments de conditionnement, qui est suffisamment étroit et suffisamment long, pour qu'une pression mécanique exercée par une main puisse transférer le contenu d'un desdits compartiments de conditionnement vers l'autre desdits compartiments de conditionnement, de manière à réaliser un cisaillement dudit contenu sortant dudit rétrécissement, ledit cisaillement homogénéisant ledit mélange de ladite première phase et de ladite deuxième phase, ledit mélange homogénéisé étant un produit cosmétique directement consommable par le consommateur final. To this end, the present invention provides a capsule, for single use, for manufacturing a cosmetic product, comprising: at least one first deformable conditioning compartment comprising a predetermined quantity of a first phase of a cosmetic product, at least a second deformable conditioning compartment comprising a predetermined quantity of a second phase of a cosmetic product, said first and second phases being different from each other, a closed passage connecting said conditioning compartments to each other, said passage being sealed with respect to the outside of said conditioning compartments, said conditioning compartments being sufficiently flexible, the outer wall of said passage being sufficiently solid and the closing of said passage being sufficiently fragile, so that a mechanical pressure exerted by one hand can open said passage while maintaining the seal of said passage relative to the outside of said conditioning compartments, said passage, once opened, comprising a narrowing between said conditioning compartments, which is sufficiently narrow and sufficiently long, so that a mechanical pressure exerted by one hand can transfer the contents of one of said conditioning compartments to the other of said conditioning compartments, so as to effect a shear of said content exiting said narrowing, said shear homogenizing said mixture of said first phase and said second phase, said homogenized mixture being a cosmetic product directly consumable by the end consumer.
La séparation des composants ou des phases du produit cosmétique personnalisé, préalablement à leur mélange, permet bien sûr une plus grande flexibilité et une plus grande richesse dans les possibilités de mélange à réaliser, c'est-à-dire un plus grand choix possible pour le consommateur final.  The separation of the components or phases of the personalized cosmetic product, prior to their mixing, of course allows greater flexibility and greater wealth in the mixing possibilities to be achieved, that is to say a greater possible choice for the end consumer.
La séparation des composants ou des phases du produit cosmétique personnalisé, préalablement à leur mélange, permet également d'une part une meilleure et une plus longue conservation avant mélange, et d'autre part permet de limiter ou même de supprimer les conservateurs qui seraient requis pour un produit conventionnel déjà mélangé lors de sa vente au consommateur final. La santé du consommateur final est alors mieux préservée.  The separation of the components or phases of the personalized cosmetic product, prior to their mixing, also allows on the one hand a better and a longer preservation before mixing, and on the other hand makes it possible to limit or even eliminate the preservatives that would be required for a conventional product already mixed when sold to the final consumer. The health of the end consumer is then better preserved.
La capsule, à usage unique, de fabrication de produit cosmétique personnalisé à partir de compartiments pré-dosés à usage unique est simultanément d'une part simple et efficace à utiliser et d'autre part son nettoyage est pratiquement inexistant ou au moins très simple et rapide à réaliser. En effet, préférentiellement, ce mélange ne sort pas, du milieu constitué d'une part par lesdits compartiments et d'autre part par le passage réalisé entre lesdits compartiments, du tout ou au moins pas avant que l'homogénéisation dudit mélange ne soit terminée. The single-use capsule for manufacturing personalized cosmetic products from single-use pre-dosed compartments is simultaneously simple and effective to use and, on the other hand, its cleaning is practically non-existent or at least very simple and quick to make. In fact, preferentially, this mixture does not come out of the medium constituted on the one hand by said compartments and on the other hand by the passage carried out between said compartments, at all or at least not until the homogenization of said mixture is complete.
Ainsi, le mélange va s'effectuer à l'intérieur du milieu constitué par les deux compartiments reliés entre eux, sans sortir de ce milieu, et donc sans risquer d'entrer en contact avec l'extérieur de la capsule, évitant ainsi de salir le milieu extérieur.  Thus, the mixture will be carried out inside the medium constituted by the two compartments connected together, without leaving this medium, and therefore without the risk of coming into contact with the outside of the capsule, thus avoiding dirtying. the external environment.
Ceci est une façon simple et efficace pour le contenu des compartiments de ne pas entrer en contact avec l'extérieur, sans nécessiter pour autant d'autres éléments supplémentaires pour réaliser le mélange, les seuls compartiments suffisant pour réaliser le mélange, un autre élément supplémentaire pouvant éventuellement être utilisé pour recevoir le mélange une fois que celui-ci est réalisé.  This is a simple and effective way for the contents of the compartments not to come into contact with the outside, without requiring other additional elements to achieve the mixture, the only compartments sufficient to achieve the mixture, another additional element may possibly be used to receive the mixture once it is made.
L'absence d'utilisation d'une quelconque machine chargée de réaliser le transfert d'un compartiment à l'autre, n'empêche pas un éventuel préchauffage de la capsule.  The absence of use of any machine responsible for carrying out the transfer from one compartment to another, does not prevent a possible preheating of the capsule.
Suivant des modes de réalisation préférés, l'invention comprend une ou plusieurs des caractéristiques suivantes qui peuvent être utilisées séparément ou en combinaison partielle entre elles ou en combinaison totale entre elles.  According to preferred embodiments, the invention comprises one or more of the following features which may be used separately or in partial combination with each other or in full combination with one another.
De préférence, ledit rétrécissement présente la forme d'un canal au moins sur une partie de sa longueur. De préférence, une fois ledit passage ouvert, ledit canal est de section constante sur la majeure partie de sa longueur, de préférence sur la totalité de sa longueur.  Preferably, said narrowing is in the form of a channel at least over part of its length. Preferably, once said passage is open, said channel is of constant section over most of its length, preferably over its entire length.
Ainsi, le couplage de l'accélération du mélange lors de la traversée du canal avec la chute de pression qui l'accompagne, suivie d'une décélération du mélange avec la remontée de pression qui l'accompagne, favorise le cisaillement du mélange après cette traversée, et par conséquent améliore l'homogénéisation de ce mélange.  Thus, the coupling of the acceleration of the mixture during the crossing of the channel with the pressure drop that accompanies it, followed by a deceleration of the mixture with the pressure rise that accompanies it, promotes the shearing of the mixture after this crossing, and therefore improves the homogenization of this mixture.
De préférence, ladite partie de canal à section constante présente une  Preferably, said constant section channel portion has a
2 2 section comprise entre 0.5 et 3 mm , de préférence entre 1 et 2 mm . Ainsi, cette faible valeur de section de canal accélère le mélange traversant le canal et fait chuter sa pression, améliorant alors le cisaillement du mélange sortant du canal, cisaillement qui, devenant plus important, améliore l'homogénéisation du mélange. 2 2 section between 0.5 and 3 mm, preferably between 1 and 2 mm. Thus, this low channel section value accelerates the mixing through the channel and lowers its pressure, thereby improving the shear of the mixture exiting the channel, shear which, becoming more important, improves the homogenization of the mixture.
De préférence, ladite partie de canal à section constante présente une longueur comprise entre 0.5 et 10 mm, de préférence comprise entre 1 et 5 mm, encore plus de préférence entre 2 et 4 mm.  Preferably, said channel section with constant section has a length of between 0.5 and 10 mm, preferably between 1 and 5 mm, more preferably between 2 and 4 mm.
Ainsi, cet effet combiné d'accélération et de chute de pression, favorisant le cisaillement du mélange sortant du canal et améliorant son homogénéisation, se produit pendant plus longtemps, pendant le temps de traversée du canal.  Thus, this combined effect of acceleration and pressure drop, favoring the shear of the mixture leaving the channel and improving its homogenization, occurs for a longer time, during the crossing time of the channel.
De préférence, lors de l'ouverture dudit passage, la section dudit canal ne s'agrandit pas sur la majeure partie de la longueur dudit canal.  Preferably, during the opening of said passage, the section of said channel does not expand over most of the length of said channel.
Ainsi, même après son ouverture, le canal conserve sa propriété de section vraiment limitée favorisant l'homogénéisation du mélange traversant ce canal.  Thus, even after opening, the channel retains its property of really limited section favoring homogenization of the mixture passing through this channel.
De préférence, ledit canal débouche dans les compartiments sans entrer dans les compartiments.  Preferably, said channel opens into the compartments without entering the compartments.
Ainsi, lorsque le mélange repart vers le compartiment d'où il venait pour une nouvelle traversée du canal, il est évité qu'une partie notable du mélange ne vienne se bloquer dans le cul-de-sac constitué par le pourtour du canal débouchant dans le compartiment. A chaque traversée du canal, une partie bloquée du mélange serait moins bien homogénéisée, et l'homogénéisation globale du mélange serait moins poussée pour un nombre donné de traversées du canal.  Thus, when the mixture returns to the compartment from which it came for a new crossing of the channel, it is avoided that a significant portion of the mixture will come jam in the cul-de-sac formed by the perimeter of the channel opening into the compartment. At each crossing of the channel, a blocked portion of the mixture would be less well homogenized, and the overall homogenization of the mixture would be less extensive for a given number of channel crossings.
De préférence, la fermeture dudit passage est assurée par un resserrement allant jusqu'au contact entre les parois dudit passage, l'ouverture dudit passage est assurée par un écartement entre lesdites parois dudit passage provoqué par la pression exercée par le contenu d'un desdits compartiments de conditionnement expulsé dudit compartiment de conditionnement sous ladite pression mécanique exercée par une main. C'est une fermeture simple facile à ouvrir pour le passage reliant les compartiments. Preferably, closing said passage is provided by a tightening up to the contact between the walls of said passage, the opening of said passage is provided by a spacing between said walls of said passage caused by the pressure exerted by the contents of one of said packaging compartments expelled from said conditioning compartment under said mechanical pressure exerted by a hand. It is a simple closure easy to open for the passage connecting the compartments.
De préférence, ledit passage est sécable de manière à pouvoir séparer entre eux lesdits compartiments de conditionnement.  Preferably, said passage is breakable so as to separate said conditioning compartments.
Ainsi, le mélange homogénéisé, constituant alors le produit cosmétique directement consommable par le consommateur final, stocké dans l'un des compartiments peut être expulsé hors de la capsule justement au niveau de la coupure de ce passage, une fois cette coupure réalisée.  Thus, the homogenized mixture, then constituting the cosmetic product directly consumable by the end consumer, stored in one of the compartments can be expelled out of the capsule precisely at the level of the cut-off of this passage, once this cut is achieved.
De préférence, lesdits compartiments de conditionnement sont chacun suffisamment volumineux pour contenir tout ledit mélange, de préférence suffisamment volumineux pour contenir une fois et quart tout ledit mélange, encore plus de préférence suffisamment volumineux pour contenir une fois et demie tout ledit mélange. Avantageusement, les capsules sont déformables mais pas extensibles.  Preferably, said conditioning compartments are each sufficiently large to contain all said mixture, preferably sufficiently bulky to contain once and a quarter all said mixture, still more preferably sufficiently bulky to contain one and half times all said mixture. Advantageously, the capsules are deformable but not extensible.
Ainsi, à chaque transfert du mélange de l'un des compartiments vers l'autre compartiment, l'intégralité du mélange traverse le rétrécissement, et pas seulement la majorité ou une partie, réduisant alors le nombre de transferts requis pour obtenir un niveau d'homogénéisation donné.  Thus, with each transfer of the mixture from one of the compartments to the other compartment, the entire mixture passes through the narrowing, and not only the majority or a part, thereby reducing the number of transfers required to obtain a level of homogenization given.
De préférence, ledit rétrécissement présente une taille ou un diamètre qui vaut au plus 20% de la taille ou du diamètre du ou des compartiments de conditionnement qui portent ledit rétrécissement, de préférence au plus 15%, encore plus de préférence au plus 12%. De préférence, ledit rétrécissement présente une taille ou un diamètre qui vaut au moins 2% de la taille ou du diamètre du ou des compartiments de conditionnement qui portent ledit rétrécissement, de préférence au moins 4%, encore plus de préférence au moins 8%.  Preferably, said narrowing has a size or diameter which is at most 20% of the size or diameter of the packaging compartment or compartments which carry said narrowing, preferably at most 15%, still more preferably at most 12%. Preferably, said narrowing has a size or diameter which is at least 2% of the size or diameter of the packaging compartment or compartments which carry said narrowing, preferably at least 4%, more preferably at least 8%.
Ces valeurs de ratios entre d'une part la taille du rétrécissement et d'autre part la taille du ou des compartiments assurent d'une part une valeur maximum préférentielle du seuil relatif de rétrécissement permettant d'obtenir un seuil particulièrement intéressant de cisaillement et donc d'homogénéisation et d'autre part une valeur minimum préférentielle du seuil relatif de rétrécissement permettant de maintenir un temps de passage avantageusement court pour effectuer le transfert du mélange d'un compartiment à l'autre. These ratio values between, on the one hand, the size of the shrinkage and, on the other hand, the size of the compartment or compartments ensure on the one hand a preferential maximum value of the relative shrinkage threshold making it possible to obtain a particularly advantageous threshold of shear and thus homogenisation and, secondly, a preferential minimum relative shrinkage threshold to maintain a passage time advantageously short to effect the transfer of the mixture from one compartment to another.
De préférence, ladite première phase est une phase grasse, ladite deuxième phase est une phase aqueuse.  Preferably, said first phase is a fatty phase, said second phase is an aqueous phase.
Ainsi, pouvoir maintenir séparées jusqu'au moment de la consommation du produit cosmétique les deux phases, grasse et aqueuse, le constituant, permet une fraîcheur optimale du produit cosmétique ainsi qu'une bonne conservation longue durée des deux phases séparées malgré l'absence totale ou quasi-totale de conservateurs dans ces deux phases.  Thus, being able to keep separated until the moment of the consumption of the cosmetic product the two phases, fatty and aqueous, the constituent, allows an optimal freshness of the cosmetic product as well as a good long-term preservation of the two separate phases in spite of the total absence or almost total of preservatives in these two phases.
De préférence, au moins l'un desdits compartiments comprend un ou plusieurs émulsionnants pour stabiliser l'homogénéité du mélange émulsionné et éviter la coalescence desdites phases.  Preferably, at least one of said compartments comprises one or more emulsifiers for stabilizing the homogeneity of the emulsified mixture and preventing the coalescence of said phases.
Ainsi, une fois l'émulsion réalisée grâce à un cisaillement et à une homogénéisation conséquente efficaces, cette émulsion est plus facile à conserver sans que ses phases constitutives ne se séparent à nouveau par coalescence de gouttelettes.  Thus, once the emulsion is produced by effective shearing and homogenization, this emulsion is easier to preserve without its constitutive phases separating again by coalescence of droplets.
De préférence, chacun desdits premier et deuxième compartiments ne comporte qu'une seule chambre.  Preferably, each of said first and second compartments has only one chamber.
Ainsi, la structure globale de la capsule est nettement plus simple. Thus, the overall structure of the capsule is much simpler.
Dans une réalisation, le contenu des compartiments est sous vide.In one embodiment, the contents of the compartments are under vacuum.
Le caractère déformable des compartiments de la capsule facilite alors l'accroissement de volume requis pour réaliser le transfert du mélange d'un compartiment à l'autre de la capsule. The deformable character of the compartments of the capsule then facilitates the increase in volume required to achieve the transfer of the mixture from one compartment to another of the capsule.
Dans une réalisation alternative, les compartiments sont des poches d'air aseptisées seulement partiellement remplies d'un ou de plusieurs constituants de produit cosmétique.  In an alternative embodiment, the compartments are sanitized air pockets only partially filled with one or more cosmetic product components.
Le caractère compressible de l'air, au contraire des constituants du produit cosmétique, sous forme liquide, facilite alors l'accroissement de volume requis pour réaliser le transfert du mélange d'un compartiment à l'autre de la capsule. De préférence, ladite fermeture dudit passage est une première soudure, et l'un desdits compartiments comprend un orifice de sortie dudit mélange homogénéisé fermé par une deuxième soudure plus solide que ladite première soudure de manière à ce qu'une pression mécanique exercée par une main puisse ouvrir ledit orifice de sortie, cette pression mécanique devant être plus forte, de préférence au moins une fois et demie plus forte, encore plus de préférence au moins deux fois plus forte, que la pression mécanique minimale nécessaire pour ouvrir ledit passage. The compressible nature of the air, unlike the constituents of the cosmetic product, in liquid form, then facilitates the increase in volume required to effect the transfer of the mixture from one compartment to the other of the capsule. Preferably, said closure of said passage is a first weld, and one of said compartments comprises an outlet of said homogenized mixture closed by a second weld stronger than said first weld so that a mechanical pressure exerted by a hand can open said outlet, this mechanical pressure to be stronger, preferably at least one and a half times stronger, more preferably at least twice as strong, as the minimum mechanical pressure necessary to open said passage.
Ainsi, un premier niveau d'effort manuel ouvre le passage et autorise le transfert du mélange entre les compartiments de la capsule, tandis qu'un deuxième niveau d'effort manuel, supérieur au premier niveau d'effort manuel, ouvre l'orifice de sortie une fois le mélange bien homogénéisé, pour expulser le mélange bien homogénéisé à l'extérieur de la capsule, pour qu'il puisse être consommé directement par le consommateur final.  Thus, a first level of manual effort opens the passage and allows the transfer of the mixture between the compartments of the capsule, while a second level of manual effort, greater than the first level of manual effort, opens the opening of once the mixture is well homogenized, to expel the well-homogenized mixture outside the capsule, so that it can be consumed directly by the end consumer.
De préférence, l'épaisseur des compartiments est comprise entre 5% et Preferably, the thickness of the compartments is between 5% and
30% de leur longueur, de préférence entre 10% et 20%> de leur longueur. De préférence, l'épaisseur des compartiments est comprise entre 10%> et 50%> de leur largeur, de préférence entre 20%> et 40%> de leur largeur. 30% of their length, preferably between 10% and 20%> of their length. Preferably, the thickness of the compartments is between 10% and 50% of their width, preferably between 20% and 40% of their width.
Ces ratios de dimensions facilitent la déformation des compartiments de la capsule, sans avoir besoin d'utiliser un matériau mou ou de faible épaisseur. Cette déformation augmente alors temporairement le ratio volume sur surface de l'un ou de l'autre des compartiments, ce qui est utile pour accueillir facilement l'ensemble du mélange traversant le passage.  These size ratios facilitate the deformation of the compartments of the capsule, without the need to use a soft or thin material. This deformation temporarily increases the volume-to-surface ratio of one or the other of the compartments, which is useful to easily accommodate the entire mixture passing through the passage.
De préférence, l'invention concerne aussi une méthode de fabrication, par le consommateur final, d'un produit cosmétique directement consommable par le consommateur final, à partir d'une capsule, à usage unique, de fabrication d'un produit cosmétique selon l'invention, caractérisé en ce que le transfert dudit mélange, d'un compartiment à l'autre, est réalisé au moins une fois, de préférence au moins deux fois, plus de préférence entre deux fois et sept fois, encore plus de préférence entre trois fois et cinq fois. Ainsi, par quelques traversées du rétrécissement, le mélange est bien homogénéisé et peut ensuite être directement consommé par le consommateur final. Preferably, the invention also relates to a method of manufacturing, by the end consumer, a cosmetic product directly consumable by the end consumer, from a single-use capsule for manufacturing a cosmetic product according to the invention. characterized in that the transfer of said mixture from one compartment to the other is carried out at least once, preferably at least twice, more preferably between two and seven times, even more preferably between three times and five times. Thus, by passing through the narrowing, the mixture is well homogenized and can then be directly consumed by the final consumer.

DETAILED DESCRIPTION OF THE INVENTION
Les figures 1A et 1B représentent schématiquement, respectivement en vue de dessus et en vue de profil, un exemple d'une capsule de fabrication selon un mode de réalisation de l'invention, représenté dans un état correspondant à une première phase d'un procédé de fabrication selon un mode de réalisation de l'invention. FIGS. 1A and 1B show schematically, respectively in plan view and in profile view, an example of a manufacturing capsule according to one embodiment of the invention, represented in a state corresponding to a first phase of a process manufacturing according to one embodiment of the invention.
Le procédé de fabrication va maintenant être décrit en liaison avec une capsule 3 contenant une première phase qui est une phase grasse et une deuxième phase qui est une phase aqueuse. La phase grasse constitue la base du produit cosmétique à fabriquer tandis que la phase aqueuse comprenant des éléments actifs constitue le complexe d'actifs du produit cosmétique à fabriquer. Le procédé de fabrication fonctionnera de manière similaire avec une phase grasse et une phase aqueuse contenant tous deux des éléments actifs, ou bien avec deux phases aqueuses, ou bien avec une autre combinaison de phases dont le mélange donnera le produit cosmétique directement consommable par le consommateur final. Le consommateur final est un terme générique qui désigne aussi bien une consommatrice finale femme qu'un consommateur final homme.  The manufacturing process will now be described in connection with a capsule 3 containing a first phase which is a fatty phase and a second phase which is an aqueous phase. The fatty phase constitutes the base of the cosmetic product to be manufactured whereas the aqueous phase comprising active elements constitutes the complex of active ingredients of the cosmetic product to be manufactured. The manufacturing process will work similarly with a fatty phase and an aqueous phase both containing active elements, or with two aqueous phases, or with another combination of phases, the mixture of which will give the cosmetic product directly consumable by the consumer final. The final consumer is a generic term that refers to both a female final consumer and a male final consumer.
Une capsule 3 comprend deux compartiments 1 et 2. Dans le compartiment 1 se trouve une première phase grasse d'un produit cosmétique. Dans le compartiment 2 se trouve une deuxième phase aqueuse d'un produit cosmétique. Les compartiments 1 et 2 sont par exemple des sachets flexibles thermo-soudés. Les compartiments 1 et 2 présentent chacun les mêmes dimensions, une longueur L, une largeur 1, une épaisseur e. Les compartiments 1 et 2 sont reliés entre eux par un passage 4 fermé, au niveau de leurs extrémités. Le passage 4 est fermé par une fermeture 5. La fermeture 5 est par exemple une zone de soudure affaiblie. Le passage 4 est un canal de section constante, sauf dans la zone de soudure. Une autre zone de soudure affaiblie, mais moins affaiblie que la fermeture 5, bouche un orifice d'évacuation 8 situé à l'autre extrémité du compartiment 1. Les compartiments 1 et 2, ainsi que le passage 4, sont étanches par rapport au milieu extérieur à la capsule 3. A capsule 3 comprises two compartments 1 and 2. In compartment 1 is a first fatty phase of a cosmetic product. In compartment 2 there is a second aqueous phase of a cosmetic product. The compartments 1 and 2 are, for example, heat-sealed flexible bags. The compartments 1 and 2 each have the same dimensions, a length L, a width 1, a thickness e. Compartments 1 and 2 are interconnected by a closed passage 4, at their ends. The passage 4 is closed by a closure 5. The closure 5 is for example a weakened welding zone. The passage 4 is a channel of constant section, except in the weld zone. Another weakened weld zone, but less weakened than the closure 5, closes an evacuation orifice 8 located at the other end of the compartment 1. compartments 1 and 2, as well as the passage 4, are sealed with respect to the medium outside the capsule 3.
La figure 2 représente schématiquement, en vue de profil, un exemple d'une capsule de fabrication selon un mode de réalisation de l'invention, représenté dans un état correspondant à une deuxième phase d'un procédé de fabrication selon un mode de réalisation de l'invention.  FIG. 2 schematically represents, in profile view, an example of a manufacturing capsule according to one embodiment of the invention, represented in a state corresponding to a second phase of a manufacturing method according to an embodiment of FIG. the invention.
Les flèches droites verticales symbolisent la pression manuelle exercée par le consommateur final. La flèche courbe horizontale symbolise le transfert du contenu d'un compartiment vers un autre compartiment de la capsule.  The vertical straight arrows symbolize the manual pressure exerted by the end consumer. The horizontal curved arrow symbolizes the transfer of the contents of one compartment to another compartment of the capsule.
Lorsque le consommateur final exerce une pression manuelle sur le compartiment 1, ce compartiment 1 s'aplatit ce qui a pour conséquence d'expulser la première phase grasse hors du compartiment 1. La première phase grasse expulsée hors du compartiment 1 traverse le canal 4 en ouvrant la fermeture 5 laquelle cède sous la pression exercée par cette première phase expulsée. La première phase grasse, après avoir traversé le canal 4, se retrouve dans le compartiment 2 où elle peut se mélanger avec la deuxième phase aqueuse contenue dans le compartiment 2, pour donner le mélange 6 lequel n'est à ce stade pas du tout homogénéisé.  When the final consumer exerts a manual pressure on the compartment 1, this compartment 1 flattens which has the effect of expelling the first fatty phase out of the compartment 1. The first fatty phase expelled out of the compartment 1 through the channel 4 in opening the closure 5 which gives way under the pressure exerted by this first expelled phase. The first fatty phase, after passing through the channel 4, is found in the compartment 2 where it can mix with the second aqueous phase contained in the compartment 2, to give the mixture 6 which is at this stage not at all homogenized .
La figure 3 représente schématiquement, en vue de profil, un exemple d'une capsule de fabrication selon un mode de réalisation de l'invention, représenté dans un état correspondant à une troisième phase d'un procédé de fabrication selon un mode de réalisation de l'invention.  FIG. 3 schematically represents, in profile view, an example of a manufacturing capsule according to one embodiment of the invention, represented in a state corresponding to a third phase of a manufacturing method according to an embodiment of FIG. the invention.
Lorsque le consommateur final exerce une pression manuelle sur le compartiment 2, ce compartiment 2 s'aplatit ce qui a pour conséquence d'expulser le mélange 6 hors du compartiment 2. Le mélange 6 expulsé hors du compartiment 2 traverse le canal 4 qui est maintenant ouvert et qui est de section constante. Le mélange 6, après avoir traversé le canal 4, se retrouve dans le compartiment 1, plus homogénéisé, grâce à sa traversée du canal 4 lequel présente une section de passage réduite par rapport à la section des compartiments 1 et 2. En effet, la restriction de section au niveau du canal 4, crée, pour le mélange 6 qui traverse le canal 4, une accélération de flux et une diminution de pression, qui contribuent, avec la réduction de section, au cisaillement des phases grasse et aqueuse contenues dans le mélange 6 pas du tout homogénéisé à la sortie du canal 4. Le mélange 6, après avoir traversé le canal 4, arrive dans le compartiment 1. Le canal 4 est de section constante. Le canal 4 est avantageusement entièrement libre de tout obstacle ou de tout grillage. Le mélange 6 subit alors une forte turbulence lorsqu'il se déverse dans le compartiment 1, car il subit tout à la fois une décélération et une remontée en pression, ce qui contribue au cisaillement des phases grasse et aqueuse contenues dans le mélange 6 pas du tout homogénéisé. Le cisaillement du mélange 6 après la traversée du canal 4, créé par cette forte turbulence, homogénéise le mélange 6 qui commence à devenir une émulsion. When the final consumer exerts a manual pressure on the compartment 2, this compartment 2 flattens which has the effect of expelling the mixture 6 out of the compartment 2. The mixture 6 expelled from the compartment 2 passes through the channel 4 which is now open and which is of constant section. The mixture 6, after passing through the channel 4, is found in the compartment 1, more homogenized, through its passage through the channel 4 which has a reduced passage section relative to the section of the compartments 1 and 2. Indeed, the restriction of section at the channel 4, creates, for the mixture 6 which passes through the channel 4, a flow acceleration and a pressure decrease, which contribute, with the reduction of section, shear fat phases and The mixture 6, after having passed through the channel 4, arrives in the compartment 1. The channel 4 is of constant section. The channel 4 is advantageously completely free of any obstacle or toasting. The mixture 6 then undergoes a strong turbulence when it pours into the compartment 1, because it undergoes both a deceleration and a rise in pressure, which contributes to the shear of the fatty and aqueous phases contained in the mixture 6 not the all homogenized. The shearing of the mixture 6 after crossing the channel 4, created by this strong turbulence, homogenizes the mixture 6 which begins to become an emulsion.
La figure 4 représente schématiquement, en vue de profil, un exemple d'une capsule de fabrication selon un mode de réalisation de l'invention, représenté dans un état correspondant à une quatrième phase d'un procédé de fabrication selon un mode de réalisation de l'invention.  FIG. 4 schematically represents, in profile view, an example of a manufacturing capsule according to one embodiment of the invention, represented in a state corresponding to a fourth phase of a manufacturing method according to an embodiment of FIG. the invention.
Lorsque le consommateur final exerce à nouveau une pression manuelle sur le compartiment 1, ce compartiment 1 s'aplatit ce qui a pour conséquence d'expulser le mélange 6 hors du compartiment 1. Le mélange 6 expulsé hors du compartiment 1 traverse le canal 4. Le mélange 6, après avoir traversé le canal 4, se retrouve dans le compartiment 2, encore plus homogénéisé, grâce à sa nouvelle traversée du canal 4 lequel présente une section de passage réduite par rapport à la section des compartiments 1 et 2.  When the final consumer again exerts manual pressure on the compartment 1, the compartment 1 flattens which has the effect of expelling the mixture 6 out of the compartment 1. The mixture 6 expelled from the compartment 1 through the channel 4. The mixture 6, after passing through the channel 4, is found in the compartment 2, even more homogenized, thanks to its new crossing of the channel 4 which has a reduced passage section relative to the section of the compartments 1 and 2.
En effet, la restriction de section au niveau du canal 4, crée, pour le mélange 6 qui traverse le canal 4, à chaque passage du mélange 6, une accélération de flux et une diminution de pression. Le mélange 6, après avoir traversé le canal 4, arrive dans le compartiment 2. Le mélange 6 subit, lorsqu'il se déverse dans le compartiment 2, tout à la fois une décélération et une remontée en pression. La combinaison successive d'une part de l'accélération et de la chute de pression d'autre part suivie par la décélération et la remontée en pression homogénéise le mélange 6 et favorise son émulsion. Indeed, the restriction of section at the channel 4, creates, for the mixture 6 which passes through the channel 4, at each passage of the mixture 6, an acceleration of flow and a decrease in pressure. The mixture 6, after passing through the channel 4, arrives in the compartment 2. The mixture 6 undergoes, when it flows into the compartment 2, both a deceleration and a rise in pressure. The successive combination of a part of the acceleration and pressure drop on the other hand followed by the deceleration and rise in pressure homogenizes the mixture 6 and promotes its emulsion.
Le cycle de traversée du canal 4 par le mélange 6 en allant d'un compartiment à l'autre, peut être répété plusieurs fois jusqu'à obtention de l'émulsion désirée. Le mélange 6 passe alternativement du compartiment 2 dans le compartiment 1 puis du compartiment 1 dans le compartiment 2, en traversant à chaque fois le canal 4. Le nombre de traversées du canal 4 effectuées par le mélange 6 peut varier selon la composition précise des phases du produit cosmétique. Un nombre de traversées compris entre 3 et 5 convient bien pour la plupart des produits cosmétiques. Le nombre de traversées du canal 4 à faire effectuer au mélange 6 est indiqué sur la capsule 3 pour le consommateur final ou sur la boîte de capsules 3.  The cycle of passage of the channel 4 by the mixture 6 going from one compartment to another, can be repeated several times until the desired emulsion is obtained. The mixture 6 passes alternately from compartment 2 into compartment 1 and then compartment 1 into compartment 2, passing through channel 4 each time. The number of passages through channel 4 made by mixture 6 can vary depending on the precise composition of the phases. of the cosmetic product. A number of crossings between 3 and 5 is suitable for most cosmetic products. The number of passages of the channel 4 to be made to the mixture 6 is indicated on the capsule 3 for the final consumer or on the box of capsules 3.
La figure 5 représente schématiquement, en vue de profil, un exemple d'une capsule de fabrication selon un mode de réalisation de l'invention, représenté dans un état correspondant à une cinquième phase d'un procédé de fabrication selon un mode de réalisation de l'invention.  FIG. 5 schematically represents, in profile view, an example of a manufacturing capsule according to one embodiment of the invention, represented in a state corresponding to a fifth phase of a manufacturing method according to an embodiment of FIG. the invention.
Une fois le nombre voulu de traversées effectuées, le mélange 6, bien homogénéisé, et le cas échéant, bien émulsionné, se retrouve dans le compartiment 1. Les compartiments 1 et 2 sont rabattus l'un sur l'autre. Le canal 4 est plié en deux, ce qui le bouche. Une pression manuelle plus importante de la part du consommateur final amène l'orifice d'évacuation 8 à s'ouvrir sous la pression du mélange 6 lequel peut alors être déversé dans une coupelle 7 pour être ensuite directement consommée par le consommateur final qui peut se l'appliquer directement sur le visage à l'aide de ses doigts.  Once the desired number of crossings carried out, the mixture 6, well homogenized, and if necessary, well emulsified, is found in the compartment 1. The compartments 1 and 2 are folded over one another. Channel 4 is folded in half, which closes it. A greater manual pressure from the end consumer causes the discharge orifice 8 to open under the pressure of the mixture 6 which can then be poured into a cup 7 to be directly consumed by the end consumer who can apply it directly to the face using his fingers.
En alternative, en l'absence d'orifice d'évacuation 8, la zone de soudure 5 affaiblie située en milieu de canal 4, peut également être sécable. Une fois le nombre voulu de traversées effectuées, le mélange 6, bien homogénéisé, et le cas échéant, bien émulsionné, se retrouve dans le compartiment 1 ou dans le compartiment 2. Les compartiments 1 et 2 sont séparés l'un de l'autre par le consommateur final qui casse la zone 5 sécable. Une pression manuelle normale de la part du consommateur final provoque l'expulsion du mélange 6 lequel peut alors être déversé dans une coupelle 7 pour être ensuite directement consommé par le consommateur final qui peut se l'appliquer directement sur le visage à l'aide de ses doigts. Alternatively, in the absence of exhaust port 8, the weakened weld zone 5 located in the middle of the channel 4 can also be divisible. Once the desired number of crossings have been carried out, the mixture 6, well homogenized and, if appropriate, well emulsified, is found in compartment 1 or in compartment 2. Compartments 1 and 2 are separated from each other by the end consumer who breaks the breakable zone 5. Normal manual pressure from the final consumer causes the expulsion of the mixture 6 which can then be poured into a cup 7 to be then directly consumed by the end consumer who can apply it directly to the face with the help of their fingers.
Bien entendu, la présente invention n'est pas limitée aux exemples et au mode de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.  Of course, the present invention is not limited to the examples and to the embodiment described and shown, but it is capable of numerous variants accessible to those skilled in the art.
