Description

La présente invention concerne un ensemble pour le conditionnement séparé et le mélange extemporané de deux produits, les deux produits étant destinés à former une composition notamment cosmétique, utilisée par exemple dans le domaine de la coloration capillaire.The present invention relates to an assembly for separate packaging and extemporaneous mixing of two products, the two products being intended to form a composition, especially a cosmetic composition, used for example in the field of hair dyeing.

Dans le domaine de la coloration à domicile, les produits sont traditionnellement conditionnés dans deux récipients. En effet, la coloration d'oxydation se compose d'une crème d'oxydation et d'une crème colorante qui sont chacune conditionnées dans un récipient différent car elles ne peuvent être mélangées qu'au moment de l'application de la composition colorante sur la chevelure.In the field of home coloring, the products are traditionally packaged in two containers. Indeed, the oxidation coloring consists of an oxidation cream and a coloring cream which are each packaged in a different container because they can be mixed only at the time of application of the dye composition on the hair.

Différents types de récipients ont déjà été utilisés pour conditionner de telles crèmes. La crème colorante est généralement contenue dans un tube en aluminium fermé par un opercule formé par une fine pellicule d'aluminium. Le tube est fermé par un bouchon muni d'un pointeau sur sa paroi supérieure externe qui est prévu pour perforer l'opercule. Un tel tube est en général formé d'une jupe fermée dans sa partie inférieure par une pliure enroulée. Un récipient de type "bouillotte" a par exemple été utilisé pour conditionner la crème d'oxydation. Plus récemment, on a remplacé la bouillotte par un tube à parois plus souples, dans lequel le colorant est introduit au moment de l'application de la composition colorante. Pour mettre les produits en contact l'un avec l'autre, il est tout d'abord nécessaire d'ouvrir le tube en aluminium et de perforer la pellicule à l'aide du pointeau en retournant le bouchon. Les deux tubes ont dans ce cas des dispositifs de couplage qui permettent de les raccorder en les fixant l'un à l'autre pour mettre les deux produits en contact.Different types of containers have already been used to package such creams. The coloring cream is usually contained in an aluminum tube closed by a cover formed by a thin film of aluminum. The tube is closed by a plug with a needle on its outer upper wall which is provided to perforate the lid. Such a tube is generally formed of a closed skirt in its lower part by a rolled fold. For example, a "hot water bottle" type container has been used to condition the oxidation cream. More recently, the hot water bottle has been replaced by a tube with softer walls, into which the dye is introduced at the time of application of the dye composition. To put the products in contact with each other, it is first necessary to open the aluminum tube and perforate the film with the needle by turning the cap. In this case, the two tubes have coupling devices that make it possible to connect them by fixing them together to put the two products in contact.

Toutefois, il arrive parfois que certains utilisateurs oublient de perforer l'opercule d'aluminium avant de coupler les deux tubes au moyen des dispositifs de couplage prévus sur chacun des tubes. On a alors proposé des ensembles pour le mélange de tels produits dans lesquels le récipient contenant la crème colorante est muni d'un dispositif de perforation.However, some users sometimes forget to puncture the aluminum seal before coupling the two tubes using the coupling devices provided on each of the tubes. Sets for mixing such products in which the container containing the coloring cream is provided with a perforating device were then proposed.

La demande de brevet FR 2 685 301 décrit notamment un ensemble constitué d'un tube qui contient la crème de coloration et d'un pot qui contient la crème d'oxydation. Le tube est muni d'un goulot fileté dont l'ouverture est fermée par un opercule déchirable. Le pot est fermé par une capsule formée d'un plateau qui porte une jupe dont la paroi interne est filetée. Une ouverture est formée au centre du plateau, à l'intérieur de la jupe filetée. L'ouverture est bordée par une couronne coupante. Pour effectuer le mélange, on visse le goulot du tube dans la jupe du pot, la couronne déchire alors l'opercule de manière à mettre le tube et le pot en communication. Toutefois, l'opercule déchiré reste dans le tube ce qui peut gêner le passage du produit. De plus, il peut arriver qu'un utilisateur ne visse pas le goulot du tube dans la jupe du pot jusqu'à ce que la couronne déchire l'opercule. L'utilisateur, pensant que l'opercule est perforé, presse ensuite le tube contenant la crème colorante, la crème ne pouvant sortir du tube par l'ouverture qui est fermée par l'opercule. Dans le cas où on utilise un tube en aluminium constitué d'une jupe dont la partie inférieure est fermée par un pliage enroulé, la pression exercée par l'utilisateur sur un tel tube a tendance, si elle est relativement importante, à faire dérouler l'extrémité du tube. La crème s'échappe alors par cette extrémité et est projetée sur l'utilisateur.The patent application FR 2,685,301 describes in particular an assembly consisting of a tube which contains the coloring cream and a pot which contains the oxidation cream. The tube is provided with a threaded neck whose opening is closed by a tear-off lid. The pot is closed by a capsule formed of a plate which carries a skirt whose inner wall is threaded. An opening is formed in the center of the tray, inside the threaded skirt. The opening is bordered by a cutting crown. To effect mixing, the neck of the tube is screwed into the skirt of the pot, the crown then ruptures the lid so as to put the tube and the pot in communication. However, the torn operculum remains in the tube which can hinder the passage of the product. In addition, it may happen that a user does not screw the neck of the tube in the skirt of the pot until the crown tears the lid. The user, thinking that the operculum is perforated, then presses the tube containing the coloring cream, the cream can not leave the tube through the opening which is closed by the lid. In the case where using an aluminum tube consisting of a skirt whose lower part is closed by a wound fold, the pressure exerted by the user on such a tube tends, if it is relatively important, to unroll the end of the tube. The cream then escapes through this end and is projected on the user.

Aussi, est-ce un des objets de l'invention que de réaliser un ensemble pour le conditionnement séparé et le mélange extemporané de deux produits destinés à former une composition cosmétique qui ne présente pas les inconvénients de la technique antérieure, et qui est notamment très sécurisé.Also, is it an object of the invention to provide an assembly for separate packaging and extemporaneous mixing of two products intended to form a cosmetic composition which does not have the disadvantages of the prior art, and which is particularly secured.

C'est en particulier un objet de l'invention que de fournir un tel ensemble qui soit économique à réaliser, fiable et simple d'utilisation.It is particularly an object of the invention to provide such a set that is economical to achieve, reliable and easy to use.

D'autres objets apparaîtront dans la description détaillée qui suit.Other objects will appear in the detailed description that follows.

Selon l'invention, ces objets sont atteints en réalisant un ensemble pour le mélange extemporané de deux produits, en vue de la réalisation d'une composition, notamment cosmétique, comprenant : a) un premier récipient contenant un premier produit et délimitant une première ouverture, ledit premier récipient étant équipé de premiers moyens de couplage; b) un second récipient contenant un second produit et définissant une seconde ouverture obturée par un opercule, ledit second récipient étant équipé de seconds moyens de couplage aptes à venir en engagement avec lesdits premiers moyens de couplage, le premier récipient comportant un organe de sécurité disposé de manière à venir en engagement avec l'opercule avant la mise en engagement desdits premier et second moyens de couplage.According to the invention, these objects are achieved by producing an assembly for the extemporaneous mixing of two products, with a view to producing a composition, in particular a cosmetic composition, comprising: a) a first container containing a first product and delimiting a first opening said first container being provided with first coupling means; b) a second container containing a second product and defining a second opening closed by a lid, said second container being equipped with second coupling means able to come into engagement with said first coupling means, the first container comprising a security member disposed so as to come into engagement with the cap before the engagement of said first and second coupling means.

Ainsi, lorsque l'utilisateur oublie d'enlever l'opercule, la mise en engagement de l'opercule sur l'organe de sécurité lui indique qu'il ne doit pas mettre en engagement les deux récipients et qu'il doit retirer l'opercule, par exemple par pelage, de manière à libérer complètement l'orifice, ou qu'il doit le perforer.Thus, when the user forgets to remove the seal, the engagement of the seal on the safety member indicates that it must not engage the two containers and must remove the operculum, for example by peeling, so as to completely release the orifice, or it must perforate.

Avantageusement, l'organe de sécurité est constitué d'un picot dont au moins une partie déborde ladite première ouverture, vers l'extérieur du premier récipient. Ainsi, le second récipient est arrêté par l'organe de sécurité, avant d'atteindre l'ouverture du premier récipient. En conséquence, la mise en engagement des deux récipients est quasiment impossible.Advantageously, the safety member is constituted by a pin of which at least a portion extends beyond said first opening, towards the outside of the first container. Thus, the second container is stopped by the safety member, before reaching the opening of the first container. As a result, the engagement of the two containers is almost impossible.

Selon un mode particulier de l'invention, le picot comporte une extrémité qui présente une surface plane apte à venir en engagement avec l'opercule. Une telle surface forme une butée qui ne peut perforer l'opercule lorsqu'un utilisateur tente de mettre le second récipient en engagement dans le premier récipient, en ayant un mouvement normal, c'est-à-dire sans forcer outre mesure.According to a particular embodiment of the invention, the pin has an end which has a flat surface capable of coming into engagement with the cap. Such a surface forms a stop that can not perforate the lid when a user tries to put the second container in engagement with the first container, having a normal movement, that is to say without forcing too much.

Avantageusement, le premier récipient comprend un élément d'ouverture apte, lors de la mise en engagement desdits premier et second moyens de couplage, à provoquer le dégagement total ou partiel de ladite seconde ouverture afin de permettre la mise en communication desdits premier et second récipients, et le mélange desdits premier et second produits. Cet élément d'ouverture est un deuxième niveau de sécurité. En effet, si un utilisateur tente d'insérer le second récipient dans le premier récipient sans avoir enlevé l'opercule et qu'il l'enfonce avec une force relativement importante, l'élément d'ouverture permet d'enlever correctement l'opercule pour libérer l'ouverture du second récipient et assurer un écoulement convenable du produit. L'élément d'ouverture permet par exemple d'enlever complètement l'opercule en affaiblissant la zone de fixation de l'opercule sur le second récipient. Selon un mode particulier de l'invention, l'élément d'ouverture comprend un dispositif de découpe, notamment sous forme d'un trocart, apte à provoquer la découpe totale ou partielle de l'opercule lors de la mise en engagement desdits premier et second moyens de couplage.Advantageously, the first container comprises an aperture element capable, during the engagement of said first and second coupling means, to cause the total or partial release of said second opening to allow the communication of said first and second containers. and mixing said first and second products. This opening element is a second level of security. Indeed, if a user tries to insert the second container into the first container without having removed the lid and that it sinks with a relatively large force, the opening element allows to properly remove the lid to release the opening of the second container and ensure a proper flow of the product. The opening element makes it possible, for example, to completely remove the lid by weakening the zone for fixing the lid on the second container. According to a particular embodiment of the invention, the opening element comprises a cutting device, in particular in the form of a trocar, capable of causing the total or partial cutting of the lid when the said first and second coupling means.

Avantageusement, le dispositif de découpe est formé dans le prolongement de l'organe de sécurité, à l'opposé de l'extrémité apte à venir en engagement avec l'opercule. Le dispositif de découpe ne pourra ainsi être utilisé que dans les cas exceptionnels où l'utilisateur aura transpercé l'opercule au moyen de l'organe de sécurité.Advantageously, the cutting device is formed in the extension of the safety member, opposite the end adapted to come into engagement with the lid. The cutting device can thus be used only in exceptional cases where the user has pierced the lid by means of the safety member.

Selon un mode particulier de l'invention, les premiers moyens de couplage sont constitués d'un premier filetage, lesdits seconds moyens de couplage étant constitués d'un second filetage complémentaire du premier. Ainsi, les deux récipients sont parfaitement fixés entre eux pour assurer la mise en contact des deux produits. Il est bien évident que tout autre type de couplage permettant une mise en communication étanche peut être utilisé, par exemple un encliquetage, un dispositif à baïonnette, un montage à coulisse, etc...According to a particular embodiment of the invention, the first coupling means consist of a first thread, said second coupling means being constituted by a second thread complementary to the first. Thus, the two containers are perfectly fixed together to ensure the contact of the two products. It is obvious that any other type of coupling allowing a sealed communication can be used, for example a snap, a bayonet device, a slide assembly, etc ...

Selon un mode de réalisation, la première ouverture du premier récipient est délimitée par une cheminée axiale portant lesdits premiers moyens de couplage et l'organe de sécurité, ladite cheminée axiale étant formée à l'intérieur d'un col formé par ledit premier récipient. La cheminée axiale est reliée au col par un élément de liaison, notamment annulaire, ledit élément de liaison comportant au moins un orifice d'évent pour permettre un échappement d'air lors de la réalisation du mélange.According to one embodiment, the first opening of the first container is delimited by an axial chimney carrying said first means of coupling and the safety member, said axial chimney being formed inside a neck formed by said first container. The axial chimney is connected to the neck by a connecting element, in particular annular, said connecting element comprising at least one vent orifice to allow air to escape during mixing.

Selon un mode préféré de l'invention, la cheminée axiale et le col forment une tête obtenue d'une seule pièce, notamment par injection, ce qui permet d'obtenir un récipient simple à réaliser et peu onéreux. Le premier récipient est alors formé d'un corps sur lequel est montée ladite tête par soudage ou collage ou par tout autre type de fixation.According to a preferred embodiment of the invention, the axial chimney and the neck form a head obtained in one piece, in particular by injection, which makes it possible to obtain a container that is simple to produce and inexpensive. The first container is then formed of a body on which said head is mounted by welding or gluing or by any other type of attachment.

Avantageusement, un bouchon amovible est prévu pour fermer l'ouverture du premier récipient et pour protéger l'organe de sécurité. Le bouchon amovible est pourvu d'une extrémité sécable de manière à servir d'embout applicateur après réalisation du mélange. Le col du premier récipient porte un filetage prévu pour assurer la fixation du bouchon amovible sur le premier récipient.Advantageously, a removable plug is provided to close the opening of the first container and to protect the safety member. The removable cap is provided with a breakable end so as to serve applicator tip after completion of mixing. The neck of the first container has a thread provided for securing the removable cap on the first container.

Le second récipient est également muni d'un bouchon amovible apte, dans une première position, à être fixé sur le second récipient via le second moyen de couplage de manière à protéger l'opercule et, dans une seconde position, à perforer l'opercule. Selon un mode de réalisation particulier, le bouchon amovible comprend une paroi portant d'un côté une jupe munie d'un filetage complémentaire du filetage du second récipient, et de l'autre côté un organe de perforation. Il suffit donc de dévisser le bouchon du second récipient et de le retourner pour appliquer l'organe de perforation sur l'opercule de manière à le perforer. Une fois découpé, l'opercule peut être retiré du second récipient par l'utilisateur. Le dispositif de perforation étant disposé sur le bouchon, il est facilement repérable par l'utilisateur de sorte que celui-ci est conduit à l'utiliser pour perforer l'opercule. On peut aussi s'affranchir de l'organe de perforation en utilisant un opercule pelable.The second container is also provided with a removable cap adapted, in a first position, to be fixed on the second container via the second coupling means so as to protect the lid and, in a second position, to perforate the lid . According to a particular embodiment, the removable cap comprises a wall carrying on one side a skirt provided with a complementary thread of the thread of the second container, and on the other side a perforating member. It is therefore sufficient to unscrew the cap of the second container and turn it to apply the perforation member on the lid so as to perforate it. Once cut, the lid can be removed from the second container by the user. The perforation device being disposed on the plug, it is easily identifiable by the user so that it is led to use it to perforate the lid. One can also get rid of the perforating member using a peelable seal.

Selon un mode de réalisation préféré, le premier récipient est constitué d'un tube, notamment en polyéthylène, à parois élastiquement déformables et le second récipient est constitué d'un tube en aluminium, l'opercule étant un film d'aluminium.According to a preferred embodiment, the first container consists of a tube, in particular of polyethylene, with elastically deformable walls and the second container consists of an aluminum tube, the lid being an aluminum film.

L'ensemble qui vient d'être décrit est particulièrement utile pour la préparation d'une composition cosmétique, notamment capillaire, ledit premier produit étant un oxydant, ledit second produit étant un colorant.The assembly which has just been described is particularly useful for the preparation of a cosmetic composition, in particular a capillary composition, said first product being an oxidant, said second product being a dye.

L'invention consiste, mis 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 :

  • la figure 1 illustre une vue en élévation du premier récipient contenant un premier produit de l'ensemble selon l'invention;
  • les figures 2A à 2H représentent différentes vues des différentes étapes de fonctionnement de l'ensemble selon l'invention dans un premier mode d'utilisation; et
  • les figures 3A à 3D représentent différentes vues des différentes étapes de fonctionnement de l'ensemble selon l'invention dans un deuxième mode d'utilisation.
The invention consists, apart from the arrangements set out above, in 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:
  • Figure 1 illustrates an elevational view of the first container containing a first product of the assembly according to the invention;
  • FIGS. 2A to 2H show different views of the various operating steps of the assembly according to the invention in a first mode of use; and
  • FIGS. 3A to 3D show different views of the various operating steps of the assembly according to the invention in a second mode of use.

L'ensemble selon l'invention comprend un premier récipient 10, représenté à la figure 1, contenant un premier produit, notamment un oxydant, et un deuxième récipient 20, représenté notamment aux figures 2C à 2F, contenant un second produit, notamment un colorant d'oxydation. Les deux produits mélangés sont destinés à former une composition capillaire.The assembly according to the invention comprises a first container 10, represented in FIG. 1, containing a first product, in particular an oxidant, and a second container 20, represented in particular in FIGS. 2C to 2F, containing a second product, in particular a dye. oxidation. The two mixed products are intended to form a hair composition.

Le premier récipient, représenté à la figure 1, est un tube 10 en polyéthylène. Il comprend un corps 11 sur lequel est montée une tête 12. La tête 12 est constituée d'un épaulement 19 qui relie le corps 11 à un col 13 fileté 17 sur sa paroi externe. Une cheminée axiale 15, coaxiale du col 13 est montée à l'intérieur de celui-ci. Un disque annulaire 18 dans lequel on prévoit des orifices d'évent 18a relie la cheminée et le col. Le disque annulaire délimite avec le col et la cheminée axiale une goulotte d'étanchéité qui permet d'assurer l'étanchéité du tube 10 fermé par un bouchon que l'on décrira ultérieurement. La cheminée 15 définit l'ouverture 14 du tube 10 qui autorise le passage de produit. La paroi interne de la cheminée 15 présente un filetage 16 qui permet, comme cela sera expliqué ultérieurement, de fixer le deuxième tube 20 sur le premier tube 10. Un picot 30, plat à son extrémité 31 qui déborde l'ouverture 14 du tube, est monté fixe à l'intérieur de la cheminée 15. Il est soutenu par une barre 33 dont chaque extrémité est fixée sur la paroi interne de la cheminée 15. La barre 33 traverse ainsi le passage formé par la cheminée sur tout son diamètre. Un couteau triangulaire 32 est formé dans la base du picot soutenue par la barre 33, à l'opposé de l'extrémité plane 31. L'ensemble de la tête 12, peut être formé d'une seule pièce, par injection.The first container, shown in Figure 1, is a tube 10 made of polyethylene. It comprises a body 11 on which is mounted a head 12. The head 12 consists of a shoulder 19 which connects the body 11 to a threaded neck 13 on its outer wall. An axial chimney 15, coaxial with the neck 13 is mounted to inside of it. An annular disk 18 in which vent openings 18a are provided connects the chimney and the neck. The annular disk delimits with the neck and the axial chimney a sealing trough which makes it possible to seal the tube 10 closed by a plug which will be described later. The chimney 15 defines the opening 14 of the tube 10 which allows the passage of product. The internal wall of the chimney 15 has a threading 16 which makes it possible, as will be explained later, to fix the second tube 20 on the first tube 10. A pin 30, flat at its end 31 which projects beyond the opening 14 of the tube, is fixed mounted inside the chimney 15. It is supported by a bar 33, each end is fixed on the inner wall of the chimney 15. The bar 33 thus crosses the passage formed by the chimney over its entire diameter. A triangular knife 32 is formed in the base of the pin supported by the bar 33, opposite the flat end 31. The assembly of the head 12, can be formed in one piece, by injection.

Le tube 10 est fermé par un bouchon amovible 40, représenté notamment à la figure 2A. Une partie de la paroi interne du bouchon 40 est munie d'un filetage complémentaire du filetage 17 du col 15 de sorte que le bouchon puisse être fixé sur le premier tube 10. Le bouchon 40 permet ainsi de fermer l'ouverture 14 du premier tube et également de protéger le picot plat 30. Une paroi annulaire 42 est avantageusement prévue à l'intérieur du bouchon pour venir se loger dans la goulotte d'étanchéité formée entre le col et la cheminée lorsque le bouchon 40 est vissé sur le tube 10. Le bouchon amovible est avantageusement pourvu d'une extrémité sécable 41 qui peut être rompue en réponse à un mouvement de torsion autour de l'axe du premier tube. Lorsque l'extrémité est retirée, un orifice est dégagé qui autorise le passage de la composition après le mélange des deux produits. Le bouchon présente une forme appropriée pour servir d'embout applicateur afin de facilement appliquer sur la chevelure la composition mélangée.The tube 10 is closed by a removable plug 40, shown in particular in Figure 2A. Part of the inner wall of the plug 40 is provided with a complementary thread of the thread 17 of the neck 15 so that the plug can be fixed on the first tube 10. The plug 40 thus makes it possible to close the opening 14 of the first tube and also to protect the flat pin 30. An annular wall 42 is advantageously provided inside the plug to be housed in the sealing channel formed between the neck and the chimney when the plug 40 is screwed onto the tube 10. The removable cap is advantageously provided with a breakable end 41 which can be broken in response to a twisting movement about the axis of the first tube. When the end is removed, an orifice is released which allows the passage of the composition after mixing the two products. The stopper has a shape suitable for use as an applicator tip to easily apply to the hair the mixed composition.

Le deuxième récipient, représenté notamment aux figures 2C à 2F, est également sous forme d'un tube 20. Il s'agit d'un tube en aluminium formé par un corps dont une extrémité se termine par un col 21, et dont l'autre extrémité, non représentée, est fermée par enroulement. Le col 21 définit une ouverture 22 qui est fermée par un opercule 23. L'opercule 23 est une fine pellicule en aluminium obtenue directement lors de la fabrication du tube en aluminium. Le col 21 présente un filetage 24 sur sa paroi externe, le filetage 24 pouvant être vissé à l'intérieur de la cheminée 15 du premier tube 10, grâce au filetage complémentaire 16 prévu sur sa paroi interne. Le second tube 20 est fermé par un bouchon cylindrique 25 formé par une paroi 27 et par une première jupe munie d'un filetage 26 complémentaire du filetage 24 du col du second tube. Un pointeau 28 est prévu sur la paroi 27, à l'opposé de la jupe filetée, pour perforer le film d'aluminium 23. Afin de protéger le pointeau, on l'entoure d'une seconde jupe qui prolonge par exemple la première jupe constituant le bouchon.The second container, shown in particular in FIGS. 2C to 2F, is also in the form of a tube 20. It is an aluminum tube formed by a body whose end ends with a neck 21, and whose other end, not shown, is closed by winding. The neck 21 defines an opening 22 which is closed by a cover 23. The cover 23 is a thin aluminum film obtained directly during the manufacture of the aluminum tube. The neck 21 has a thread 24 on its outer wall, the thread 24 can be screwed inside the chimney 15 of the first tube 10, thanks to the complementary thread 16 provided on its inner wall. The second tube 20 is closed by a cylindrical plug 25 formed by a wall 27 and by a first skirt provided with a thread 26 complementary to the thread 24 of the neck of the second tube. A needle 28 is provided on the wall 27, opposite the threaded skirt, to perforate the aluminum film 23. In order to protect the needle, it is surrounded by a second skirt which extends for example the first skirt constituting the plug.

L'ensemble qui vient d'être décrit est utilisé de la façon suivante, représentée aux figures 2A à 2H. L'utilisateur dispose tout d'abord d'un tube 10 contenant une crème d'oxydant, le tube 10 étant fermé par son bouchon 40 tel que représenté à la figure 2A. Il enlève le bouchon 40 pour libérer l'ouverture 14 du tube 10, comme cela est illustré à la figure 2B. L'utilisateur dispose d'autre part du tube 20 contenant une crème colorante, et qui est fermé par son bouchon 25 (figure 2C). L'utilisateur dévisse le bouchon 25, l'opercule 23 maintenant encore le tube fermé (figure 2D). Le bouchon est ensuite retourné et engagé autour du col 21 du tube. Le pointeau 28 s'engage à l'intérieur du col 21 et transperce l'opercule 23 comme cela est représenté à la figure 2E. L'ouverture 22 du tube 20 est alors dégagée (figure 2F). L'utilisateur peut ensuite engager par vissage le col 21 du tube 20 à l'intérieur de la cheminée axiale 15 du tube 10, comme on l'a illustré aux figures 2G et 2H. L'utilisateur vide ensuite le tube 20 en pressant ses parois et transvase l'ensemble de la crème colorante dans le tube 10 contenant la crème oxydante. L'utilisateur revisse ensuite le bouchon 40 sur le tube 10, puis agite le tube 10 ainsi fermé pour homogénéiser le mélange. Enfin, il casse l'extrémité 41 du bouchon et applique la composition de coloration de manière classique.The assembly which has just been described is used as follows, shown in FIGS. 2A to 2H. The user firstly has a tube 10 containing an oxidant cream, the tube 10 being closed by its plug 40 as shown in FIG. 2A. It removes the plug 40 to release the opening 14 of the tube 10, as shown in Figure 2B. On the other hand, the user disposes of the tube 20 containing a coloring cream, and which is closed by its stopper 25 (FIG. 2C). The user unscrews the cap 25, the lid 23 now still closed tube (Figure 2D). The cap is then turned and engaged around the neck 21 of the tube. The needle 28 engages inside the neck 21 and pierces the lid 23 as shown in Figure 2E. The opening 22 of the tube 20 is then released (Figure 2F). The user can then threadingly engage the neck 21 of the tube 20 within the axial shaft 15 of the tube 10, as illustrated in Figures 2G and 2H. The user then empties the tube 20 by pressing its walls and transfers all of the coloring cream into the tube 10 containing the oxidizing cream. The user then revises the cap 40 on the tube 10, then agitates the tube 10 thus closed to homogenize the mixture. Finally, it breaks the end 41 of the stopper and applies the coloring composition in a conventional manner.

Lorsque l'opercule n'a pas été perforé avant la mise en engagement des deux tubes, l'ensemble selon l'invention est utilisé de la manière illustrée aux figures 3A à 3D. Là encore, l'utilisateur dispose du tube 10 contenant une crème d'oxydant, le tube 10 étant fermé par son bouchon 40 qu'il dévisse pour libérer l'ouverture 14 du tube 10 (figures 3A et 3B). Le tube 20 fermé par son opercule 23 est alors mis en engagement dans le tube 10, comme on l'a illustré à la figure 3C. L'opercule 23 vient alors en butée contre l'extrémité 31 du picot plat 30 qui déborde l'ouverture 14 du tube 10 sans que le col 21 du tube 20 puisse s'engager dans la cheminée 15 du récipient 10. A ce stade, l'utilisateur, sentant une résistance, est amené à arrêter son mouvement d'engagement et à retirer l'opercule à l'aide du pointeau 28 prévu sur le bouchon 25 du tube 20. Il peut alors visser le col 21 du tube 20 dans la cheminée 15 du tube 10 comme cela est illustré aux figures 2G et 2H.When the lid has not been perforated before the engagement of the two tubes, the assembly according to the invention is used in the manner illustrated in Figures 3A to 3D. Again, the user has the tube 10 containing an oxidizer cream, the tube 10 being closed by its cap 40 that unscrews to release the opening 14 of the tube 10 (Figures 3A and 3B). The tube 20 closed by its cover 23 is then engaged in the tube 10, as illustrated in Figure 3C. The lid 23 then abuts against the end 31 of the flat pin 30 which projects beyond the opening 14 of the tube 10 without the neck 21 of the tube 20 being able to engage in the chimney 15 of the container 10. At this stage, the user, feeling a resistance, is brought to stop its engagement movement and to remove the lid with the needle 28 provided on the plug 25 of the tube 20. It can then screw the neck 21 of the tube 20 in the chimney 15 of the tube 10 as illustrated in Figures 2G and 2H.

Toutefois, si l'utilisateur poursuit la mise en engagement des deux tubes sans enlever l'opercule, il doit enfoncer le col 21 du tube 20 dans la cheminée 15 du tube 10 avec une force telle que le picot plat 30 déchire l'opercule 23. Le vissage du col 21 dans la cheminée 15 est alors possible. Au cours du vissage, le couteau triangulaire 32 découpe l'opercule perforé de manière à parfaitement dégager l'ouverture 22 du tube 20 (figure 3D). Comme décrit précédemment, l'utilisateur vide la crème colorante dans le tube 10, effectue le mélange et applique la composition de coloration obtenue sur la chevelure.However, if the user continues to engage the two tubes without removing the lid, it must push the neck 21 of the tube 20 in the chimney 15 of the tube 10 with a force such that the flat pin 30 tears the operculum 23 The screwing of the neck 21 into the chimney 15 is then possible. During screwing, the triangular knife 32 cuts the operculum perforated so as to clear the opening 22 of the tube 20 (Figure 3D). As described above, the user empties the coloring cream in the tube 10, performs the mixing and applies the coloring composition obtained on the hair.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après. In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations may be made without departing from the spirit of the invention as claimed hereinafter.
