Description

L'invention concerne un emballage pour emballer un premier fluide et un deuxième fluide, le deuxième fluide étant séparé du premier, dans lequel l'emballage comporte une première partie permettant d'emballer un premier fluide et une deuxième partie permettant d'emballer un deuxième fluide, dans lequel la première partie et la deuxième partie sont adaptées pour se déplacer d'une première position, dans lequel la première partie et la deuxième partie sont séparées, vers une deuxième position permettant le mélange du premier fluide et du deuxième fluide.The invention relates to a package for packaging a first fluid and a second fluid, the second fluid being separated from the first, wherein the package comprises a first portion for packaging a first fluid and a second portion for packaging a second fluid. fluid, wherein the first portion and the second portion are adapted to move from a first position, wherein the first portion and the second portion are separated, to a second position for mixing the first fluid and the second fluid.

Un dispositif pour emballer un premier fluide et un deuxième fluide et permettant d'éviter que les deux fluides ne se mélangent avant leur utilisation, est déjà connu de l'art antérieur. Lorsque le produit doit être utilisé, l'emballage est manipulé pour permettre le mélange de fluides à l'intérieur dudit emballage, permettant ainsi à l'utilisateur d'exposer le mélange des deux fluides à l'extérieur de l'emballage.A device for packaging a first fluid and a second fluid and to prevent the two fluids from mixing before use, is already known from the prior art. When the product is to be used, the package is manipulated to allow the mixing of fluids within said package, thereby allowing the user to expose the mixture of the two fluids to the outside of the package.

Un tel dispositif est décrit, entre autres, dans le document DE19917942 . Ce document divulgue un emballage qui comporte une première partie adaptée pour contenir un premier fluide, par exemple sous forme liquide.Such a device is described, inter alia, in the document DE19917942 . This document discloses a package that includes a first portion adapted to contain a first fluid, for example in liquid form.

Le dispositif comporte une deuxième partie adaptée pour contenir un deuxième fluide, par exemple sous forme de poudre.The device comprises a second portion adapted to contain a second fluid, for example in powder form.

Dans le cas où l'utilisateur souhaite utiliser le mélange du produit à l'intérieur de l'emballage, il doit, dans un premier temps, déplacer la deuxième partie par rapport à la première partie de l'emballage afin de supprimer l'obstacle existant entre les deux compartiments et permettre le mélange entre les deux fluides contenus dans l'emballage.In the case where the user wishes to use the mixture of the product inside the package, it must, initially, move the second part relative to the first part of the package in order to remove the obstacle existing between the two compartments and allow mixing between the two fluids contained in the package.

Selon DE19917942 , le deuxième fluide contenu dans la deuxième partie est couvert à l'aide d'une couche de protection. Le fluide contenu dans la première partie de l'emballage est protégé à l'aide d'un élément amovible, adapté pour être déplacé d'une première position de fermeture vers une deuxième position d'ouverture.according to DE19917942 the second fluid contained in the second part is covered with a protective layer. The fluid contained in the first part of the package is protected by means of a removable element, adapted to be moved from a first closed position to a second open position.

Cet élément de fermeture est pourvu, en son côté inférieur, d'une perforateur qui, en déplaçant la première partie par rapport à la deuxième partie du récipient, est capable de perforer la couche de protection qui protège le contenu de la deuxième partie.This closure element is provided, at its lower side, with a perforator which, by moving the first part relative to the second part of the container, is capable of perforating the protective layer which protects the contents of the second part.

Un inconvénient majeur du dispositif selon DE19917942 réside dans le fait que l'élément permettant de fermer la première partie de l'emballage comporte un élément non fixé qui, après utilisation et étant amovible, pénètre à l'intérieur de l'emballage. A l'intérieur de cet emballage, l'élément amovible peut former un obstacle pouvant empêcher, d'une part, un mélange optimal du premier fluide et du deuxième fluide et, d'autre part, empêcher une expulsion correcte desdits fluides vers l'extérieur de l'emballage.A major drawback of the device according to DE19917942 resides in the fact that the element allowing to close the first part of the package comprises an unfixed element which, after use and being removable, penetrates inside the package. Inside this package, the removable element can form an obstacle that can prevent, on the one hand, an optimal mixture of the first fluid and the second fluid and, on the other hand, prevent a proper expulsion of said fluids to the outside the package.

Un second inconvénient, lié au premier, réside dans le fait que le processus d'ouverture des deux compartiments n'est pas assuré dans le cas où l'élément de fermeture du premier compartiment est déplacé vers une deuxième position avant que l'ouverture de la deuxième partie ne soit effective.A second disadvantage, related to the first, lies in the fact that the opening process of the two compartments is not ensured in the case where the closure element of the first compartment is moved to a second position before the opening of the second part is effective.

De plus, le récipient selon DE19917942 , est adapté pour séparer correctement les deux fluides contenus à l'intérieur du dispositif dans une première position dudit dispositif. Les fluides contenus à l'intérieur du dispositif peuvent, dans la deuxième position dudit dispositif, être mélangés.In addition, the container according to DE19917942 , is adapted to correctly separate the two fluids contained inside the device in a first position of said device. The fluids contained inside the device may, in the second position of said device, be mixed.

Le dispositif selon l'art antérieur est surtout développé pour fournir un mécanisme permettant d'ouvrir les deux récipients à l'intérieur du dispositif. Aucune mesure n'est prise pour un conditionnement idéal des fluides contenus à l'intérieur du dispositif. En d'autres termes, les fluides contenus à l'intérieur du dispositif selon DE19917942 peuvent, pendant le stockage dudit dispositif, être exposés à l'influence de l'oxygène O2 et H2O pouvant pénétrer à l'intérieur des récipients du dispositif.The device according to the prior art is mainly developed to provide a mechanism for opening the two containers inside the device. No measures are taken for ideal conditioning of the fluids contained within the device. In other words, the fluids contained inside the device according to DE19917942 may, during storage of said device, be exposed to the influence of oxygen O 2 and H 2 O can penetrate inside the containers of the device.

Le but de la présente invention est de fournir un dispositif d'emballage permettant d'emballer deux fluides à l'intérieur de compartiments distincts dans lequel ledit dispositif d'emballage est pourvu d'un mécanisme permettant le mélange des deux fluides, à un moment choisi par l'utilisateur, en évitant les inconvénients liés au dispositif connu dans l'art antérieur.The object of the present invention is to provide a packaging device for packaging two fluids within separate compartments wherein said packaging device is provided with a mechanism for mixing the two fluids at a time. chosen by the user, avoiding the disadvantages associated with the device known in the prior art.

Selon l'invention, le dispositif est adapté pour protéger de façon optimale les fluides contenus à l'intérieur dudit dispositif, dans leur compartiment respectif distinct, avant le mélange des fluides contenus dans le dispositif au moment choisi par l'utilisateur.According to the invention, the device is adapted to optimally protect the fluids contained within said device, in their respective separate compartment, before mixing the fluids contained in the device at the moment chosen by the user.

La figure 1 montre un dispositif 10, selon la présente invention, permettant d'emballer deux produits séparément, dans lequel ledit dispositif 10 est adapté pour permettre le mélange de ces deux produits à un moment choisi par l'utilisateur.The figure 1 shows a device 10, according to the present invention, for packaging two products separately, wherein said device 10 is adapted to allow the mixing of these two products at a time chosen by the user.

Le dispositif 10 comporte une première partie 1 et une deuxième partie 2. La première partie 1 est adaptée pour contenir un premier fluide, tel qu'un liquide 30. La première partie 1 est pourvue d'une paroi 11, par exemple de forme cylindrique. Une première extrémité est fermée grâce à un bouchon 12. Comme montré en figure 4, le bouchon 12 est connecté aux parois 11 et peut être déplacé d'une position fermée, tel que montré en figure 1, vers une position ouverte, tel que montré en figure 4, afin de libérer le contenu du dispositif 10 lorsque les deux produits à l'intérieur dudit dispositif 10 sont mélangés.The device 10 comprises a first part 1 and a second part 2. The first part 1 is adapted to contain a first fluid, such as a liquid 30. The first part 1 is provided with a wall 11, for example of cylindrical shape . A first end is closed by means of a plug 12. As shown in FIG. figure 4 , the plug 12 is connected to the walls 11 and can be moved from a closed position, as shown in FIG. figure 1 , to an open position, as shown in figure 4 , in order to release the contents of the device 10 when the two products inside said device 10 are mixed.

La paroi 11 comprend un élément de fermeture 13 permettant de fermer, au côté opposé, le compartiment chargé de contenir le liquide 30. Cet élément 13 comporte une paroi 14, sous forme d'un élément sécable, pouvant se déplacer d'une position initiale, tel que montré en figure 1 et dans laquelle la paroi 14 est adapté pour contenir le liquide 30 à l'intérieur de la première partie 1, vers une position d'utilisation, tel que montré en figure 2, dans laquelle la paroi 14 permet le mélange du fluide 30 avec le produit contenu dans la deuxième partie 2.The wall 11 comprises a closure element 13 making it possible to close, at the opposite side, the compartment responsible for containing the liquid 30. This element 13 comprises a wall 14, in the form of a breakable element, which can move from an initial position , as shown in figure 1 and wherein the wall 14 is adapted to contain the liquid 30 within the first portion 1 towards a use position, as shown in FIG. figure 2 , in which the wall 14 allows the fluid 30 to be mixed with the product contained in the second part 2.

L'élément de fermeture 13 de la première partie 1 est ainsi pourvu d'un élément de perforation 15. Cet élément de perforation 15 est directement connecté à l'intérieur de la paroi 11 de la première partie 1. L'élément de perforation 15 est adapté pour perforer l'élément qui protège le produit contenu dans la deuxième partie 2 et permet à cette protection d'être ouverte afin d'autoriser le mélange des deux produits contenus dans le dispositif 10.The closure element 13 of the first part 1 is thus provided with a perforation element 15. This perforation element 15 is directly connected inside the wall 11 of the first part 1. The perforation element 15 is adapted to perforate the element that protects the product contained in the second part 2 and allows this protection to be opened in order to allow mixing of the two products contained in the device 10.

Il est important de noter que la première partie 1 peut être adaptée pour être conditionnée dans des environnements aseptiques. De plus, la première partie 1 doit être adaptée pour permettre de conserver la stérilisation du contenu 30 à l'intérieur de la première partie 1.It is important to note that the first part 1 can be adapted to be packaged in aseptic environments. In addition, the first part 1 must be adapted to allow sterilization of the contents 30 to be preserved inside the first part 1.

La figure 1 montre également la deuxième partie 2 qui est adaptée pour contenir le fluide tel qu'une poudre 40. La deuxième partie est pourvue d'une paroi extérieure 21, elle-même adaptée pour être reçue à l'intérieur de la paroi 11 de la première partie 1. Les dimensions de la paroi 21 et de la paroi 11 sont définies afin d'assurer un contact parfaitement étanche entre l'intérieur de la paroi 11 et l'extérieur de la paroi 21, que ce soit avant, pendant ou après le mélange des produits contenus à l'intérieur de la première partie 1 et de la deuxième partie 2.The figure 1 also shows the second part 2 which is adapted to contain the fluid such as a powder 40. The second part is provided with an outer wall 21, itself adapted to be received inside the wall 11 of the first Part 1. The dimensions of the wall 21 and the wall 11 are defined to ensure a perfectly tight contact between the inside of the wall 11 and the outside of the wall 21, whether before, during or after the mixture of the products contained within the first part 1 and the second part 2.

La deuxième partie 2 comprend, tel que montré plus en détail en figure 2, un premier élément 22 et un deuxième élément 23. Une couche de protection 24 est apposée entre le premier élément 22 et le deuxième élément 23. La présence de cette couche de protection 24 revêt une importance particulière car elle assure le conditionnement de la poudre 40 à l'intérieur de la deuxième partie 2. La couche de protection 24 assure une imperméabilité à l'oxygène O2 et H2O.The second part 2 includes, as shown in more detail in figure 2 , a first element 22 and a second element 23. A protective layer 24 is affixed between the first element 22 and the second element 23. The presence of this protective layer 24 is of particular importance because it ensures the conditioning of the powder 40 inside the second part 2. The protective layer 24 ensures impermeability to oxygen O 2 and H 2 O.

La couche de protection 24 peut contenir une feuille d'aluminium et peut être constituée par une multicouche de polyoléfine et aluminium, par exemple une première couche de polyoléfine, une seconde couche d'aluminium et une autre couche de polyoléfine.The protective layer 24 may contain an aluminum foil and may consist of a polyolefin and aluminum multilayer, for example a first polyolefin layer, a second aluminum layer and another polyolefin layer.

Un mode de réalisation pour produire la deuxième partie 2 est décrit en faisant référence aux figures 5, 6 et 7.An embodiment for producing the second part 2 is described with reference to the Figures 5, 6 and 7 .

Comme montré en figure 1, la deuxième partie 2 est pourvue d'un élément de percussion 25. L'élément de percussion 25 est connecté aux parois inférieures de la deuxième partie 2 et est adapté pour exercer une pression sur la paroi 14, ayant la forme d'un élément sécable, afin de permettre à cette paroi 14, ayant la forme d'un élément sécable, d'être déplacée de sa position initiale vers sa position d'utilisation, tel que montré en figure 2.As shown in figure 1 the second part 2 is provided with a percussion element 25. The percussion element 25 is connected to the lower walls of the second part 2 and is adapted to exert a pressure on the wall 14, having the shape of an element breakable, to allow this wall 14, having the form of a breakable element, to be moved from its initial position to its position of use, as shown in FIG. figure 2 .

Afin de conditionner, de façon optimale, le deuxième produit, se présentant sous la forme d'une poudre 40, à l'intérieur de la deuxième partie 2, cette deuxième partie 2 est pourvue d'une couche de protection, par exemple une feuille d'aluminium 26.In order to condition, optimally, the second product, in the form of a powder 40, inside the second part 2, this second part 2 is provided with a protective layer, for example a sheet of aluminum 26.

La fonctionnalité du dispositif 10 selon la présente invention sera mieux comprise en comparant les figures 1 et 2. Dans la figure 1, le premier produit, se présentant sous la forme d'un liquide 30, est contenu à l'intérieur de la première partie 1. Le conditionnement du liquide 30, à l'intérieur de la première partie 1, est assuré par l'ensemble des parois 11, le bouchon 12 et l'élément de fermeture 13. Grâce à ces différents éléments, le liquide 30 situé à l'intérieur de la première partie 1 conserve toute son intégrité.The functionality of the device 10 according to the present invention will be better understood by comparing the figures 1 and 2 . In the figure 1 the first product, in the form of a liquid 30, is contained inside the first part 1. The conditioning of the liquid 30, inside the first part 1, is ensured by the whole walls 11, the plug 12 and the closure element 13. With these different elements, the liquid 30 located inside the first part 1 retains its integrity.

De façon simultanée, le deuxième produit, se présentant sous la forme d'une poudre 40, est conditionné de façon optimale dans la deuxième partie 2, en utilisant les différents éléments 22 et 23 de cette deuxième partie 2 en combinaison avec les couches de protection 24 et 26. Comme montré en figure 1, les deux produits 30 et 40 sont contenus à l'intérieur du dispositif 10 sans qu'aucun mélange entre les deux produits ne soit possible.Simultaneously, the second product, in the form of a powder 40, is optimally packaged in the second part 2, using the different elements 22 and 23 of this second part 2 in combination with the protective layers 24 and 26. As shown in figure 1 the two products 30 and 40 are contained inside the device 10 without any mixing between the two products is possible.

Afin de libérer les produits 30 et 40, permettant ainsi le mélange entre les deux parties, l'utilisateur doit exercer une pression sur la première partie et sur la deuxième partie afin d'assurer que la deuxième partie 2 soit reçue à l'intérieur de la paroi 11. Ce déplacement de la première partie par rapport à la deuxième partie peut être obtenu en mettant la deuxième partie sur un support, puis en appuyant sur le bouchon 12. Toute autre méthode adaptée peut être utilisée pour s'assurer que la deuxième partie pénètre à l'intérieur de la paroi 11.In order to release the products 30 and 40, thus allowing the mixing between the two parts, the user must exert pressure on the first part and on the second part to ensure that the second part 2 is received inside the two parts. the wall 11. This movement of the first part relative to the second part can be obtained by putting the second part on a support, then pressing the plug 12. Any other suitable method can be used to ensure that the second part penetrates inside the wall 11.

Lorsque la deuxième partie 2 a pénétré à l'intérieur de la paroi 11 de la première partie 1, on obtient la situation telle que montrée en figure 2. Le déplacement de la première partie 1 par rapport à la deuxième partie 2 a eu pour effet de perforer la couche de protection 26 et ce, grâce à l'élément de perforation 15.When the second part 2 has penetrated inside the wall 11 of the first part 1, the situation as shown in FIG. figure 2 . The displacement of the first part 1 relative to the second part 2 had the effect of perforating the protective layer 26 and this, thanks to the perforation element 15.

Comme montré en figure 2, en combinaison avec la figure 4, l'élément de perforation 15 a été formé pour permettre la découpe d'une partie de la périphérie de la couche de protection 26. En d'autres termes, la couche de périphérie 26 reste, pour partie, fixée à la deuxième partie 2.As shown in figure 2 , in combination with the figure 4 the perforating element 15 has been formed to allow the cutting of a part of the periphery of the protective layer 26. In other words, the peripheral layer 26 remains, in part, fixed to the second part 2 .

Afin d'assurer cette fonctionnalité, l'élément de perforation 15 peut se présenter sous la forme d'un col adapté pour ouvrir les trois quarts de la périphérie de la couche de protection 26. En conservant la connexion du quart restant de la périphérie de la couche de protection 26 avec la deuxième partie 2, on évite la pénétration de ladite couche de protection 26 à l'intérieur de la première partie 1, formant ainsi un obstacle.In order to ensure this functionality, the perforation element 15 may be in the form of a neck adapted to open three-quarters of the periphery of the protective layer 26. Keeping the connection of the remaining quarter of the periphery of the the protective layer 26 with the second part 2, it prevents the penetration of said protective layer 26 inside the first part 1, thereby forming an obstacle.

De plus, la connexion partielle assurée entre la couche de protection 26 et la deuxième partie 2 permet d'éviter que cette couche de protection ne soit expulsée du dispositif 10, libérant ainsi le mélange hors de l'intérieur dudit dispositif 10.In addition, the partial connection provided between the protective layer 26 and the second part 2 makes it possible to prevent this protective layer from being expelled from the device 10, thus releasing the mixture from the inside of said device 10.

En même temps que l'élément de perforation 15 perfore la couche de protection 26, la paroi sous forme d'un élément sécable 14 est déplacée, à l'aide de l'élément de percussion 25, de sa position initiale, tel que montré en figure 1, vers sa position d'utilisation, tel que montré en figure 2.At the same time that the perforation element 15 perforates the protective layer 26, the wall in the form of a breakable element 14 is displaced, with the aid of the striking element 25, from its initial position, as shown in figure 1 towards its position of use, as shown in figure 2 .

De façon similaire à la couche de protection 26, cette paroi 14 en forme d'un élément sécable reste, pour une partie de sa périphérie, connectée à la première partie du dispositif 10. Cela signifie que la paroi 14, après le déplacement de la première partie 1 par rapport à la deuxième partie 2, ne peut en aucun cas devenir un obstacle à l'intérieur du dispositif 10 selon l'invention et ne peut pas non plus être expulsée dudit dispositif 10.In a manner similar to the protective layer 26, this wall 14 in the form of a breakable element remains, for part of its periphery, connected to the first part of the device 10. This means that the wall 14, after the displacement of the first part 1 relative to the second part 2, can in no case become an obstacle inside the device 10 according to the invention nor can it be expelled from said device 10.

Lorsque la deuxième partie 2 a pénétrée à l'intérieur de la paroi 11 de la première partie 1, telle que montré en figure 2, les deux produits 30 et 40 peuvent entrer en contact afin d'obtenir un mélange de ces deux produits 30 et 40.When the second part 2 has penetrated inside the wall 11 of the first part 1, as shown in FIG. figure 2 both products 30 and 40 may come into contact to obtain a mixture of these two products 30 and 40.

Afin d'obtenir un mélange optimal du liquide 30 et de la poudre 40, le dispositif 10 peut être agité avant d'ouvrir le bouchon 12 et libérer ainsi le mélange 30/40 du dispositif 10.

  • La figure 3 montre la deuxième partie 2 du dispositif 10 selon la présente invention. Cette figure 3 présente en détail l'élément de percussion 25 qui se présente essentiellement sous la forme d'une croix comprenant quatre ailes.
  • La figure 3 montre également que la deuxième partie 2 est pourvue, en son extérieur, de rainures 27 adaptées pour coopérer avec des rainures présentes à l'intérieur de la paroi 11, permettant d'assurer l'étanchéité entre la première partie 1 et la deuxième partie 2, une fois que le mélange entre les deux produits présents à l'intérieur du dispositif 10 est permis.
  • La figure 4 montre le dispositif 10 avant son assemblage et permet de décrire le fond de la première partie 1 et plus spécifiquement la forme du perforateur 15. Comme indiqué en figure 4, le perforateur 15 se présente essentiellement sous la forme d'un col. Il n'effectue pas un cercle continu mais est pourvu d'un secteur 16 ayant deux fonctions.
In order to obtain an optimal mixture of the liquid 30 and the powder 40, the device 10 can be agitated before opening the cap 12 and thus free the mixture 30/40 of the device 10.
  • The figure 3 shows the second part 2 of the device 10 according to the present invention. This figure 3 shows in detail the percussion element 25 which is essentially in the form of a cross comprising four wings.
  • The figure 3 also shows that the second part 2 is provided, on its outside, grooves 27 adapted to cooperate with grooves present inside the wall 11, for sealing between the first part 1 and the second part 2 once the mixture between the two products present inside the device 10 is allowed.
  • The figure 4 shows the device 10 before assembly and allows to describe the bottom of the first part 1 and more specifically the shape of the perforator 15. As indicated in figure 4 the perforator 15 is essentially in the form of a neck. It does not perform a continuous circle but is provided with a sector 16 having two functions.

La première des fonctions du secteur 16 est d'assurer une perforation de la feuille de protection 26 se limitant aux trois quarts de sa périphérie, par appui sur le perforateur 15. A l'endroit où se trouve le secteur 16, la couche de protection 26 est maintenue et n'est pas altérée.The first of the functions of the sector 16 is to ensure a perforation of the protective sheet 26 being limited to three quarters of its periphery, by pressing the perforator 15. At the location where the sector 16 is, the protective layer 26 is maintained and is not impaired.

L'autre fonction du secteur 16 permet de s'assurer que l'élément 14 en forme de d'un élément sécable reste fixé aux parois 11 de la première partie 1 après son ouverture.The other function of the sector 16 ensures that the element 14 in the form of a breakable element remains attached to the walls 11 of the first part 1 after opening.

Les figures 5, 6 et 7 montrent en détail, et étape par étape, le procédé de fabrication de la deuxième partie 2 du dispositif selon la présente invention.The Figures 5, 6 and 7 show in detail, and step by step, the method of manufacturing the second part 2 of the device according to the present invention.

Comme montré en figure 5, le premier élément 22 de la deuxième partie 2 est obtenu grâce à un processus d'injection plastique réalisé, par exemple, à l'aide d'un moule rotatif ou à transfert Comme clairement visible en figure 5, le premier élément 22 comprend, entre autres, l'élément de percussion 25.As shown in figure 5 , the first element 22 of the second part 2 is obtained by means of a plastic injection process carried out, for example, using a rotary or transfer mold As clearly visible in FIG. figure 5 the first element 22 comprises, inter alia, the percussion element 25.

La seconde partie du processus est montré en figure 6. La feuille de protection 24 est mise en forme par un procédé de formation à froid puis est disposée, par un robot, sur le premier élément 22. Comme indiqué ci-dessus, la couche de protection 24 peut comprendre tout matériau adapté mais est, de préférence, constitué d'une multicouche de polyoléfine, puis d'aluminium puis encore de polyoléfine. La couche de protection 24 est maintenue, par serrage diamétral, par la forme 50 sur le premier élément 22 de la deuxième partie 2.The second part of the process is shown in figure 6 . The protective sheet 24 is shaped by a cold forming process and is then arranged by a robot on the first element 22. As indicated above, the protective layer 24 may comprise any suitable material but is preferably, consisting of a polyolefin multilayer, then aluminum and then polyolefin. The protective layer 24 is maintained, by diametric clamping, by the shape 50 on the first element 22 of the second part 2.

Le second élément 23 est réalisé par une deuxième injection plastique à l'aide d'un processus de « surmoulage ». Ce procédé permet un recollement chimique et mécanique entre le premier élément 22 et le deuxième élément 23 de la deuxième partie 2. Cela signifie que la connexion entre le premier élément 22 et le deuxième élément 23 est parfaitement assurée et que la feuille de protection 24 est correctement fixée. Lorsque la deuxième partie 2 selon la figure 7 est obtenue, l'espace à l'intérieur de cette deuxième partie 2 peut être utilisée pour y disposer une poudre 40. Quand la poudre 40 est reçue à l'intérieur du deuxième élément 2, celui-ci peut être fermé à l'aide de la couche de protection 26. En d'autres termes, cette poudre 40 est protégée par une couche parfaitement étanche et résistante à l'introduction de l'oxygène ou H2O.The second element 23 is made by a second plastic injection using an "overmoulding" process. This method allows a chemical and mechanical bonding between the first element 22 and the second element 23 of the second part 2. This means that the connection between the first element 22 and the second element 23 is perfectly ensured and that the protective sheet 24 is correctly fixed. When the second part 2 according to the figure 7 is obtained, the space inside this second part 2 can be used to dispose of it a powder 40. When the powder 40 is received inside the second element 2, it can be closed using the protective layer 26. In other words, this powder 40 is protected by a layer perfectly tight and resistant to the introduction of oxygen or H 2 O.

Un avantage du dispositif 10 selon la présente invention réside dans le fait que la première partie 1 et la deuxième partie 2 peuvent être préparées, de façon individuelle, avant leur assemblage. Les deux récipients 1 et 2 peuvent être conditionnés dans des environnements différents et donc pouvant être spécifiques à l'un (le liquide) ou à l'autre (la poudre) des produits contenus dans les deux récipients.An advantage of the device 10 according to the present invention lies in the fact that the first part 1 and the second part 2 can be prepared, individually, before assembly. The two containers 1 and 2 can be packaged in different environments and therefore can be specific to one (the liquid) or the other (the powder) of the products contained in the two containers.
