Abstract

The device has a chamber (5) delimited by a closing unit (4) connected to a container (2) through an intermediate piece (3). The unit is passed, in response to activation control, relative to the piece from a configuration in which the container and chamber are isolated to another configuration in which the container and chamber are communicated. The piece is removable relative to the container and has a tubular channel (21) communicating with the container. The unit has a sealing body (6) around which the chamber is defined, where the body seals the container prior to the activation control. An independent claim is also included for a method for conditioning a cosmetic products mixing device.

Description

La présente invention a pour objet un dispositif pour la mise en contact extemporanée d'au moins deux produits, en particulier deux produits cosmétiques, conditionnés séparément, et un ensemble pour la distribution de la composition obtenue du mélange de ces deux produits. En particulier, l'invention est utile pour la préparation extemporanée d'une composition cosmétique de traitement capillaire et sa distribution.The present invention relates to a device for putting in extemporaneous contact at least two products, in particular two cosmetics, packaged separately, and a set for the distribution of the composition obtained from the mixture of these two products. In particular, the invention is useful for the extemporaneous preparation of a cosmetic hair treatment composition and its distribution.

Par « produit cosmétique », on entend un produit tel que défini dans la Directive 93/35/CEE du Conseil du 14 juin 1993."Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

Dans le domaine de la coloration capillaire, la préparation de bon nombre de compositions de coloration implique le mélange extemporané de deux produits, généralement un colorant et un oxydant qui, pour des raisons de stabilité doivent être maintenus à l'écart l'un de l'autre jusqu'au moment de l'utilisation de la composition de coloration.In the field of hair dyeing, the preparation of a large number of coloring compositions involves the extemporaneous mixing of two products, generally a dye and an oxidant which, for reasons of stability, must be kept away from one another. other until the moment of use of the coloring composition.

Ces dernières années ont vu, dans le domaine de la coloration capillaire, l'apparition de dispositifs de mélange, permettant, de manière plus ou moins automatique, le conditionnement séparé de deux produits, et leur mélange extemporané au moment de l'utilisation de la composition de coloration. De tels systèmes sont coûteux et compliqués à réaliser. Les étanchéités entre les deux compartiments contenant chacun lesdits produits est difficile à réaliser, notamment lorsque la séparation prévue entre ces compartiments se présente sous la forme d'un film destiné à être déchiré lors de la mise en communication des compartiments. En outre, il est parfois difficile de trouver des matériaux, compatibles avec les produits à conditionner, en raison de la forte agressivité d'au moins certains de ces derniers.In recent years have seen, in the field of hair coloring, the appearance of mixing devices, allowing, more or less automatically, the separate packaging of two products, and their extemporaneous mixture at the time of use of the coloring composition. Such systems are expensive and complicated to make. The seals between the two compartments each containing said products is difficult to achieve, especially when the separation provided between these compartments is in the form of a film to be torn when placing the compartments in communication. In addition, it is sometimes difficult to find materials, compatible with the products to be packaged, because of the high aggressiveness of at least some of the latter.

Dans des domaines différents, ayant des problématiques différentes de distribution du mélange de produits obtenu, on connaît du document US-6,045,245 , des biberons prêts à l'emploi comportant deux compartiments séparés. Le corps de ces biberons n'est pas standard et comporte un étranglement annulaire à distance du col sur lequel une tétine peut être montée. Un organe de fermeture est monté sur ce corps pour coopérer avec l'étranglement annulaire et fermer un premier compartiment. Cet organe de fermeture définit le fond d'un deuxième compartiment. Le problème posé par ce type de biberons tient au fait que les deux compartiments sont difficiles à remplir. Du document US-3,651,990 , on connaît un dispositif du type précédemment décrit présentant également des problèmes pour le remplissage et la fermeture du deuxième compartiment.In different fields, having different problems of distribution of the product mixture obtained, document is known US 6045245 , ready-to-use bottles with two separate compartments. The body of these bottles is not standard and has an annular constriction away from the neck on which a pacifier can be mounted. A closure member is mounted on this body to cooperate with the annular constriction and close a first compartment. This closure member defines the bottom of a second compartment. The problem with this type of bottle is that both compartments are difficult to fill. Of the document US 3651990 a device of the previously described type is known which also has problems for filling and closing the second compartment.

On connaît aussi du document DE 299 16 436 un dispositif pour le mélange extemporané de deux produits, le premier produit étant contenu dans un récipient et le second produit étant contenu isolément dans une chambre d'un organe de fermeture dudit récipient. Le mélange des deux produits est obtenu par simple coulissement de l'organe de fermeture relativement au récipient. En effet, la chambre de l'organe de fermeture est initialement obturée par une pièce intermédiaire de montage dudit organe de fermeture sur le récipient, tel que lors du coulissement, la chambre est ouverte et des passages ménagés dans cette pièce intermédiaire autorisent la mise en communication de la chambre avec le récipient. Le produit s'écoule au travers de ces passages, le cas échéant par gravité depuis la chambre vers le récipient.Document is also known DE 299 16 436 a device for the extemporaneous mixing of two products, the first product being contained in a container and the second product being contained in isolation in a chamber of a closing member of said container. The mixture of the two products is obtained by simply sliding the closure member relative to the container. Indeed, the chamber of the closure member is initially closed by an intermediate piece for mounting said closure member on the container, such that during sliding, the chamber is open and passages in this intermediate piece allow the implementation of communication of the chamber with the container. The product flows through these passages, if necessary by gravity from the chamber to the container.

Ce type de dispositif pose un problème car les passages ménagés pour permettre l'écoulement du produit empêchent un écoulement rapide et intégral du produit contenu dans ladite chambre. En effet, ces passages sont ménagés entre des ponts de matière reliant un élément d'obturation de la pièce intermédiaire permettant d'obturer la chambre aux moyens de fixation de cette pièce intermédiaire dans le col du récipient. Le nombre de passages est identique au nombre de ponts de matière, le flux de produit sortant de la chambre étant divisé en autant de flux qu'il y a de passages. De fait, il y a des risques de bouchage de ces passages, et le mélange obtenu risque alors de ne pas correspondre à celui attendu par la consommatrice. La fiabilité et la répétitivité des mélanges obtenus par l'intermédiaire de tels dispositifs ne sont pas garanties.This type of device is a problem because the passages arranged to allow the flow of the product prevent a rapid and complete flow of the product contained in said chamber. Indeed, these passages are formed between material bridges connecting a closure element of the intermediate piece for closing the chamber to the attachment means of this intermediate piece in the neck of the container. The number of passages is identical to the number of bridges of material, the product flow leaving the chamber being divided into as many streams as there are passages. In fact, there is a risk of clogging of these passages, and the mixture obtained may then not match that expected by the consumer. The reliability and repeatability of mixtures obtained through such devices are not guaranteed.

Aussi, est-ce un des objets de la présente invention que de réaliser un dispositif pour le conditionnement séparé et la distribution conjointe de deux produits, qui résolve en tout ou partie les problèmes évoqués ci-dessus.Also, is it an object of the present invention to provide a device for the separate packaging and the joint distribution of two products, which solves all or part of the problems mentioned above.

A cet effet l'invention a pour objet un dispositif pour la mise en contact extemporanée d'au moins deux produits conditionnés séparément dans respectivement un premier et un second compartiment,
le premier compartiment étant délimité par un récipient,
le second compartiment étant délimité au moins en partie par un corps relié par une pièce intermédiaire au récipient, ce corps formant un organe de fermeture amovible du récipient,

La figure 1 montre un dispositif 1 selon l'invention comportant un récipient 2 équipé d'une pièce intermédiaire 3 surmontée d'un organe de fermeture 4 du récipient 2.FIG. 1 shows a device 1 according to the invention comprising a container 2 equipped with an intermediate piece 3 surmounted by a closure member 4 of the container 2.

En particulier, le récipient 2 est en verre transparent et a une contenance comprise entre 10 et 100 mL, et de préférence de l'ordre de 25mL. Le récipient 2 contient un premier produit P1 de préférence liquide. Le récipient 2 est représenté de forme légèrement tronconique entre son fond et un épaulement au niveau duquel est présentée la pièce intermédiaire 3 et l'organe de fermeture 4. En variante, le récipient 2 peut comporter un étranglement à distance du fond et de l'épaulement. Dans ce cas, l'étranglement est de préférence positionné de telle sorte que la section transversale du récipient au niveau de l'épaulement soit identique, voire superposable, à celle au niveau du fond. De tels récipients présentent l'avantage d'être faciles à convoyer sur des lignes de conditionnement.In particular, the container 2 is made of transparent glass and has a capacity of between 10 and 100 ml, and preferably of the order of 25 ml. The container 2 contains a first product P1 preferably liquid. The container 2 is represented with a slightly frustoconical shape between its bottom and a shoulder at which the intermediate part 3 and the closure member 4 are presented. In a variant, the container 2 may comprise a constriction at a distance from the bottom and the shoulder. In this case, the constriction is preferably positioned so that the cross section of the container at the shoulder is identical or even superimposable to that at the bottom. Such containers have the advantage of being easy to convey on packaging lines.

L'organe de fermeture 4 délimite une chambre 5, Figure 2, autour d'un organe d'étanchéité 6 dépassant d'un fond 7 de l'organe de fermeture. L'organe d'étanchéité 6 est dressé perpendiculairement au fond 7 le long d'un axe X. L'organe d'étanchéité 6 peut se présenter sous la forme d'un picot creux ou plein. II définit une paroi délimitant en partie la chambre 5, cette dernière étant définie autour de cet organe d'étanchéité 6.The closure member 4 delimits a chamber 5, Figure 2, around a sealing member 6 protruding from a bottom 7 of the closure member. The sealing member 6 is erected perpendicularly to the bottom 7 along an axis X. The sealing member 6 may be in the form of a hollow or full pin. It defines a wall partially delimiting the chamber 5, the latter being defined around this sealing member 6.

La chambre 5 est délimitée en partie par le fond 7. Elle est délimitée intérieurement par l'organe d'étanchéité 6, et extérieurement par une paroi tubulaire 8 également dressée sur ce fond 7. La paroi tubulaire 8 entoure l'organe d'étanchéité 6. La paroi tubulaire 8 est également dressée perpendiculairement au fond 7 le long de l'axe X. La chambre 5 est délimitée entre l'organe d'étanchéité 6 et la paroi tubulaire 8, qui peuvent être respectivement de toute section transversale.The chamber 5 is delimited in part by the bottom 7. It is delimited internally by the sealing member 6, and externally by a tubular wall 8 also erected on the bottom 7. The tubular wall 8 surrounds the sealing member 6. The tubular wall 8 is also erected perpendicular to the bottom 7 along the axis X. The chamber 5 is delimited between the sealing member 6 and the tubular wall 8, which can be respectively of any cross section.

L'organe d'étanchéité 6 est de préférence tubulaire creux, il présente par exemple une section transversale extérieure circulaire. La paroi tubulaire 8 présente par exemple une section transversale intérieure circulaire, d'un diamètre supérieur à celui de l'organe d'étanchéité 6, de telle sorte que la paroi tubulaire 8 et l'organe d'étanchéité 6 sont définis de manière concentrique autour de l'axe X. La chambre 5 est alors de section annulaire.The sealing member 6 is preferably hollow tubular, it has for example a circular outer cross section. The tubular wall 8 has, for example, a circular inner cross-section with a diameter greater than that of the sealing member 6, so that the tubular wall 8 and the sealing member 6 are concentrically defined. around the X axis. The chamber 5 is then of annular section.

La chambre 5 a une contenance comprise entre 1 et 20 mL, de préférence de l'ordre de 5mL. La chambre 5 est prévue pour contenir un second produit P2 différent du premier produit P1. De préférence, le second produit P2 est également liquide. En particulier, le mélange des produits P1 et P2 n'est pas stable, et les produits P1 et P2 sont stockés isolément l'un de l'autre de telle sorte que le mélange ne soit réalisé qu'au moment où l'application du mélange est voulue.The chamber 5 has a capacity of between 1 and 20 ml, preferably of the order of 5 ml. The chamber 5 is provided to contain a second product P2 different from the first product P1. Preferably, the second product P2 is also liquid. In particular, the mixture of the products P1 and P2 is not stable, and the products P1 and P2 are stored in isolation from one another so that the mixture is produced only when the application of the mixing is desired.

L'axe X correspond à l'axe longitudinal selon lequel les coupes des Figures 3, 4 et 6 sont réalisées. En effet, l'organe de fermeture 4 étant prévu pour obturer le récipient 2, il est monté sur ce récipient de telle sorte que l'axe X se superpose à un axe longitudinal et ou un axe de symétrie de révolution du récipient 2.The X axis corresponds to the longitudinal axis in which the sections of Figures 3, 4 and 6 are made. Indeed, the closure member 4 being designed to close the container 2, it is mounted on this container so that the axis X is superimposed on a longitudinal axis and or an axis of symmetry of revolution of the container 2.

La chambre 5 est prévue pour être isolée du contenu du récipient 2 dans une première configuration de stockage dans laquelle le dispositif 1 est fermé. A cet effet, la pièce intermédiaire 3 permet d'obturer la chambre 5 dans une première configuration. Le montage de l'organe de fermeture 4 sur la pièce intermédiaire 3 étant réversible, l'utilisateur peut amener la pièce intermédiaire 3 dans une seconde configuration relativement à l'organe de fermeture 4 dans laquelle la chambre 5 n'est plus obturée. L'organe de fermeture 4 est monté de manière amovible sur le récipient 2.The chamber 5 is intended to be isolated from the contents of the container 2 in a first storage configuration in which the device 1 is closed. AT this effect, the intermediate part 3 allows to close the chamber 5 in a first configuration. The mounting of the closure member 4 on the intermediate part 3 being reversible, the user can bring the intermediate piece 3 in a second configuration relative to the closure member 4 in which the chamber 5 is no longer closed. The closure member 4 is removably mounted on the container 2.

De préférence, dans la seconde configuration, la chambre 5 qui est alors ouverte peut être mise en communication avec le contenu du récipient 2. Le second produit P2 s'écoule par gravité dans le récipient 2 lorsque ce dernier repose sur une surface plane de telle sorte que l'axe longitudinal X se dresse perpendiculairement à cette surface.Preferably, in the second configuration, the chamber 5 which is then open can be placed in communication with the contents of the container 2. The second product P2 flows by gravity into the container 2 when the latter rests on a flat surface of such so that the longitudinal axis X stands perpendicular to this surface.

Figure 3, la pièce intermédiaire 3 est montée sur un col 9 du récipient 2. Le col 9 délimite une ouverture du récipient 2, cette ouverture étant en particulier définie transversalement à l'axe X.Figure 3, the intermediate part 3 is mounted on a neck 9 of the container 2. The neck 9 defines an opening of the container 2, this opening being in particular defined transversely to the axis X.

La pièce intermédiaire 3 comporte une première jupe 10 présentant des moyens pour la fixation de la pièce intermédiaire 3 sur le récipient 2. A cet effet, le pourtour extérieur du récipient 2, et en particulier de son col 9, présente au moins un ergot 11 apte à coopérer par encliquetage avec un bourrelet complémentaire 12 présenté sur un pourtour intérieur de la première jupe 10. L'ergot 11 est par exemple annulaire et le bourrelet complémentaire 12 se présente sous la forme de segments discontinus équirépartis sur le pourtour intérieur de la première jupe 10.The intermediate piece 3 comprises a first skirt 10 having means for fixing the intermediate piece 3 on the container 2. For this purpose, the outer periphery of the container 2, and in particular of its neck 9, has at least one lug 11 adapted to cooperate by snapping with a complementary bead 12 presented on an inner periphery of the first skirt 10. The lug 11 is for example annular and the complementary bead 12 is in the form of discontinuous segments evenly distributed around the inner periphery of the first skirt 10.

Cette coopération a pour objet d'immobiliser axialement la pièce intermédiaire 3 relativement au récipient 2. De préférence, cet encliquetage est prévu de sorte que manuellement il ne soit pas configuré pour tolérer un détachement de la pièce intermédiaire 3 du récipient 2 dans des conditions normales d'utilisation.This cooperation is intended to axially immobilize the intermediate part 3 relative to the container 2. Preferably, this snap is provided so that manually it is not configured to tolerate detachment of the intermediate part 3 of the container 2 under normal conditions use.

De plus, pour pouvoir immobiliser en rotation la pièce intermédiaire 3 relativement au récipient 2, la première jupe 10 comporte au niveau de son pourtour intérieur un relief apte à coopérer avec des reliefs du pourtour extérieur du col 9. En particulier, le col 9 comporte au moins une nervure 13 longitudinale apte à coopérer avec l'une quelconque des rainures 14 complémentaires prévues sur le pourtour intérieur de la première jupe 10. En effet, le pourtour intérieur de cet première jupe 10 présente continûment des rainures telles que 14 apte à coopérer avec la nervure 13 de telle sorte que la pièce intermédiaire 3 peut être montée sur le récipient 2 sans avoir besoin d'indicer leurs positions respectives lors de leur mise en engagement.In addition, in order to immobilize in rotation the intermediate part 3 relative to the container 2, the first skirt 10 has at its inner periphery a relief adapted to cooperate with reliefs of the outer periphery 9. In particular, the neck 9 comprises at least one longitudinal rib 13 adapted to cooperate with any one of the complementary grooves 14 provided on the inner periphery of the first skirt 10. In fact, the inner periphery of this first skirt 10 has continuously grooves such that 14 adapted to cooperate with the rib 13 so that the intermediate part 3 can be mounted on the container 2 without the need to index their respective positions when they are engaged.

En particulier, pour répartir les efforts qui ne manquerait pas de s'appliquer sur ces rainures 14 lorsque l'organe de fermeture 4 est entraînée en rotation relativement à la pièce intermédiaire 3, le col 9 comporte une deuxième nervure diamétralement opposée, et deux jeux de deux nervures adjacentes disposées respectivement selon une position angulaire à 90° relativement à la première nervure 13. Avant le montage de l'unité, formée par l'organe de fermeture 4 et la pièce intermédiaire 3, sur le récipient 2, les rainures 14 facilitent également la manipulation de l'organe de fermeture 4, notamment en vue de son montage sur la pièce intermédiaire 3.In particular, to distribute the forces that would not fail to apply to these grooves 14 when the closure member 4 is rotated relative to the intermediate part 3, the neck 9 has a second rib diametrically opposite, and two games of two adjacent ribs respectively disposed in a 90 ° angular position relative to the first rib 13. Prior to assembly of the unit, formed by the closure member 4 and the intermediate piece 3, on the container 2, the grooves 14 also facilitate the manipulation of the closure member 4, in particular with a view to its mounting on the intermediate piece 3.

La pièce intermédiaire 3 est montée sur le récipient de manière étanche. A cet effet, elle comporte une collerette 15 depuis laquelle est dressée la première jupe 10, cette collerette 15 étant configurée pour venir en appui contre un rebord de l'ouverture ménagée par le col 9. En particulier, la pièce intermédiaire 3 comporte une première jupe d'étanchéité 16 concentrique à la première jupe 10 et également dressée depuis cette collerette 15 de manière à venir en contact étanche avec le pourtour intérieur du col 9.The intermediate piece 3 is mounted on the container sealingly. For this purpose, it comprises a collar 15 from which is raised the first skirt 10, this flange 15 being configured to bear against a rim of the opening formed by the neck 9. In particular, the intermediate part 3 comprises a first sealing skirt 16 concentric with the first skirt 10 and also erected from this collar 15 so as to come into sealed contact with the inner periphery of the neck 9.

Pour faciliter la mise en place de la pièce intermédiaire 3 sur le récipient 2, elle est de préférence réalisée dans un matériau thermoplastique tel que du polyéthylène, notamment du polyéthylène haute densité. Elle peut être obtenue par injection.To facilitate the introduction of the intermediate part 3 on the container 2, it is preferably made of a thermoplastic material such as polyethylene, especially high density polyethylene. It can be obtained by injection.

Pour permettre le montage de l'organe de fermeture 4 sur le récipient 2, l'organe de fermeture 4 est monté sur la pièce intermédiaire 3. A cet effet, la pièce intermédiaire 3 comporte une seconde jupe 17 dressée depuis la collerette 15 dans une direction opposée à la première jupe 10. Cette seconde jupe 17 présente des moyens de fixation aptes à coopérer de manière réversible avec l'organe de fermeture 4. En particulier, la seconde jupe 17 présente un filetage 18 sur son pourtour extérieur apte à coopérer avec un filetage complémentaire 19 d'une jupe externe de montage 20 de l'organe de fermeture 4.To enable the closure member 4 to be mounted on the container 2, the closure member 4 is mounted on the intermediate piece 3. For this purpose, the intermediate piece 3 comprises a second skirt 17 raised from the collar 15 in a direction opposite to the first skirt 10. This second skirt 17 has fastening means able to cooperate reversibly with the closure member 4. In particular, the second skirt 17 has a thread 18 on its outer circumference adapted to cooperate with a complementary thread 19 of an outer mounting skirt 20 of the closure member 4.

La jupe de montage 20 entoure la paroi tubulaire 8 de telle sorte que la seconde jupe 17 se situe entre la jupe de montage 20 et la paroi tubulaire 8 lorsque l'organe de fermeture 4 est monté sur la pièce intermédiaire 3.The mounting skirt 20 surrounds the tubular wall 8 so that the second skirt 17 is located between the mounting skirt 20 and the tubular wall 8 when the closure member 4 is mounted on the intermediate piece 3.

Dans la première configuration, dans laquelle la pièce intermédiaire 3 obture la chambre 5, une face 24 de la collerette 15 opposée à celle en appui contre le rebord du col 9 vient fermer annulairement la chambre 5. En effet, l'organe d'étanchéité 6 est, dans cette première configuration, en partie inséré de manière étanche dans le canal 21 latéralement défini par la première jupe d'étanchéité 16.In the first configuration, in which the intermediate part 3 closes the chamber 5, a face 24 of the flange 15 opposite that abutting against the rim of the neck 9 annulously closes the chamber 5. In effect, the sealing member 6 is, in this first configuration, partly sealed in the channel 21 laterally defined by the first sealing skirt 16.

Le canal 21 peut, lorsqu'il est dégagé, permettre la communication entre la chambre 5 et l'intérieur du récipient 2, et de facto le mélange des produits qui y sont respectivement contenus. La coopération entre l'organe d'étanchéité 6 et la première jupe d'étanchéité 16 assure l'étanchéité de la fermeture de ce canal 21, et donc l'étanchéité de la fermeture du récipient 2.The channel 21 can, when it is clear, allow the communication between the chamber 5 and the interior of the container 2, and de facto the mixture of the products which are respectively contained therein. The cooperation between the sealing member 6 and the first sealing skirt 16 seals the closure of this channel 21, and thus the sealing of the closure of the container 2.

Par ailleurs pour assurer l'étanchéité de la fermeture de la chambre 5, la pièce intermédiaire 3 comporte de plus une seconde jupe d'étanchéité 22 destinée à coopérer de manière étanche, dans la première configuration, avec le pourtour intérieur de la paroi tubulaire 8. En effet, la seconde jupe d'étanchéité 22 comporte un bourrelet 23 sur son pourtour extérieur pour venir au contact de la paroi tubulaire 8 et assurer un joint annulaire par contact mécanique.Moreover, to ensure the tightness of the closure of the chamber 5, the intermediate piece 3 further comprises a second sealing skirt 22 designed to cooperate sealingly, in the first configuration, with the inner periphery of the tubular wall 8 Indeed, the second sealing skirt 22 comprises a bead 23 on its outer periphery to come into contact with the tubular wall 8 and provide an annular seal by mechanical contact.

Ainsi l'étanchéité de la fermeture de la chambre 5 est assurée d'une part par le contact entre l'organe d'étanchéité 6 et la première jupe d'étanchéité 16 et d'autre part par le contact entre le bourrelet 23 et la paroi tubulaire 8. Dans cette première configuration, les produits P1 et P2 sont isolés l'un de l'autre.Thus the sealing of the closure of the chamber 5 is provided firstly by the contact between the sealing member 6 and the first sealing skirt 16 and secondly by the contact between the bead 23 and the In this first configuration, the products P1 and P2 are isolated from one another.

Dès lors que l'utilisateur du dispositif 1 souhaite effectuer le mélange de ces deux produits, l'utilisateur amène l'organe de fermeture 4 dans une seconde configuration dans laquelle le canal 21 est dégagé. Pour ce faire, l'organe de fermeture 4 est coulissé par dévissage le long de l'axe X relativement à la pièce intermédiaire 3 qui reste solidaire du récipient 2. Par ce mouvement de l'organe de fermeture 4, l'organe d'étanchéité 6 et la paroi tubulaire 8 sont de facto translatés d'autant le long de l'axe X. Dès que l'utilisateur amorce le dévissage, l'étanchéité entre la seconde jupe d'étanchéité 22 et la paroi tubulaire 8 est rompue, de sorte que le dévissage ne conduit pas à une dépressurisation de la chambre 5.As soon as the user of the device 1 wishes to mix these two products, the user brings the closing member 4 into a second configuration in which the channel 21 is disengaged. To do this, the closure member 4 is slid by unscrewing along the axis X relative to the intermediate piece 3 which remains integral with the container 2. By this movement of the closure member 4, the body of 6 and the tubular wall 8 are de facto translated along the X axis. As soon as the user initiates unscrewing, the seal between the second sealing skirt 22 and the tubular wall 8 is broken, so that the unscrewing does not lead to a depressurization of the chamber 5.

Par ailleurs, dès que le l'étanchéité entre la première jupe d'étanchéité 16 et l'organe d'étanchéité 6 est rompu, le produit réparti annulairement autour de cet organe d'étanchéité 6 s'écoule dans un flux convergent au travers du canal 21. Le canal 21 étant délimité par la première jupe d'étanchéité 16 accolée au pourtour intérieur du col 9, le canal 21 permet un flux de produit sensiblement identique au flux maximum toléré via ce col 9.Moreover, as soon as the seal between the first sealing skirt 16 and the sealing member 6 is broken, the product distributed annularly around this sealing member 6 flows in a convergent flow through the channel 21. The channel 21 being delimited by the first sealing skirt 16 contiguous to the inner periphery of the neck 9, the channel 21 allows a product flow substantially identical to the maximum flow tolerated via this collar 9.

De plus la face 24 de la collerette 15 délimitant en partie la chambre 5 présente une surface tronconique de manière à favoriser la convergence des flux vers le canal 21.In addition, the face 24 of the flange 15 delimiting in part the chamber 5 has a frustoconical surface so as to favor the convergence of the fluxes towards the channel 21.

La durée d'écoulement du produit P2 vers le récipient 2 dépendant de la nature et de la quantité de ce produit P2, il est prévu de maintenir l'organe de fermeture 4 sur la pièce intermédiaire 3 dans la seconde configuration pendant une période suffisante pour s'assurer que tout le produit P2 s'est dévidé dans le récipient 2. De plus, cette seconde configuration du dispositif 1 est prévue pour permettre de secouer l'ensemble en vue d'homogénéiser le mélange sans risques de dispersion du mélange hors du dispositif. A cet effet, l'utilisateur est invité à ne pas dévisser complètement l'organe de fermeture pour le laisser dans cette seconde configuration.The flow time of the product P2 to the container 2 depending on the nature and the quantity of this product P2, it is expected to maintain the closure member 4 on the intermediate part 3 in the second configuration for a period sufficient to ensure that all the product P2 has flowed into the container 2. In addition, this second configuration of the device 1 is provided to allow shaking all to homogenize the mixture without risk of dispersion of the mixture out of the device. For this purpose, the user is invited not to completely unscrew the closure member to leave it in this second configuration.

Un moyen sensitif d'identification de cette seconde configuration est prévu. En effet, dès lors que le dévissage a amené le dispositif dans une position correspondant sensiblement à la seconde configuration, il est prévu un point dur de coopération entre la pièce intermédiaire 3 et l'organe de fermeture 4. Ce point dur est par exemple obtenu par une amenée en butée, Figure 4, au cours du dévissage, d'un ergot 25 présenté sur le pourtour intérieur de la paroi tubulaire 8 avec le bourrelet 23 prévu sur le pourtour extérieur de la seconde jupe d'étanchéité 22. En particulier, la paroi tubulaire 8 comporte quatre ergots équirépartis. L'utilisateur est dans un premier temps invité à ne pas dépasser ce point dur, et à agiter l'ensemble pour améliorer le mélange des produits.Sensitive means for identifying this second configuration is provided. Indeed, since the unscrewing has brought the device into a position corresponding substantially to the second configuration, there is provided a hard point of cooperation between the intermediate part 3 and the closure member 4. This hard point is for example obtained by an abutment, Figure 4, during unscrewing, d a lug 25 presented on the inner periphery of the tubular wall 8 with the bead 23 provided on the outer periphery of the second sealing skirt 22. In particular, the tubular wall 8 has four lugs equidistributed. The user is initially invited not to exceed this hard point, and to agitate all to improve the mix of products.

Dans cette seconde configuration, l'organe de fermeture 4 est toujours monté sur la pièce intermédiaire 3, mais le contact entre le ou les ergots 25 et le bourrelet 23 n'est pas étanche. De cette absence d'étanchéité, les risques de projection ou de fuite sont inexistants dans les conditions recommandées d'utilisation et de manipulation du dispositif 1.In this second configuration, the closure member 4 is always mounted on the intermediate piece 3, but the contact between the lug (s) 25 and the bead 23 is not sealed. From this lack of sealing, the risks of projection or leakage are non-existent under the recommended conditions of use and manipulation of the device 1.

Dès lors que le mélange est réalisé, pour permettre la distribution de ce mélange, l'utilisatrice retire l'organe de fermeture 4 en continuant le dévissage et en passant le point dur. De préférence l'organe de fermeture 4 est réalisé dans un matériau plus rigide que la pièce intermédiaire 3. Par exemple il est réalisé dans un matériau thermoplastique tel que du polypropylène, de manière à assurer un bon serrage radial sur la pièce intermédiaire 3. Il est par exemple obtenu par injection. De préférence, pour faciliter la manutention et l'entraînement en rotation de l'organe de fermeture, ce dernier présente un pourtour extérieur strié.Once the mixture is made, to allow the distribution of this mixture, the user removes the closure member 4 by continuing the unscrewing and passing the hard point. Preferably, the closing member 4 is made of a material that is more rigid than the intermediate piece 3. For example, it is made of a thermoplastic material such as polypropylene, so as to ensure a good radial clamping on the intermediate piece 3. is for example obtained by injection. Preferably, to facilitate the handling and the rotational drive of the closure member, the latter has a ribbed outer periphery.

Lorsque l'organe de fermeture 4 est détaché du récipient 2, la pièce intermédiaire 3 est laissé sur le récipient 2 de manière à former un support pour recevoir un organe de distribution 26, Figure 6.When the closure member 4 is detached from the container 2, the intermediate piece 3 is left on the container 2 so as to form a support for receiving a dispensing member 26, Figure 6.

L'organe de distribution 26 comporte une enveloppe extérieure 27 munie d'une jupe filetée 28 apte à se visser sur le filetage 18 prévu sur la seconde jupe 17 de la pièce intermédiaire. L'organe de distribution 26 retient un corps de pompe 29, ce corps de pompe 29 étant surmonté d'un bouton poussoir 30. Le bouton poussoir 30 forme un organe d'actionnement du corps de pompe 29. Il présente un orifice de distribution 31 via lequel le mélange de produit peut être expulsé. L'actionnement du bouton poussoir 30 est obtenu par un enfoncement le long de l'axe longitudinal X. Le corps de pompe 29 est par exemple muni d'un tube plongeur 32, ce dernier s'étendant alors au travers du canal 21 à l'intérieur du récipient 2.The dispensing member 26 comprises an outer casing 27 provided with a threaded skirt 28 adapted to be screwed onto the thread 18 provided on the second skirt 17 of the intermediate piece. The dispensing member 26 retains a pump body 29, this pump body 29 being surmounted by a push button 30. The push button 30 forms an actuating member of the pump body 29. It has a dispensing orifice 31 via which the product mixture can be expelled. The actuation of the push button 30 is obtained by a depression along the longitudinal axis X. The pump body 29 is for example provided with a dip tube 32, the latter then extending through the channel 21 to the inside the container 2.

De préférence, l'organe de distribution 26 est monté de manière étanche sur le récipient 2. En particulier, une coupelle 33 entourant le corps de pompe 29 est retenue de manière étanche à l'intérieur de l'enveloppe extérieure 27. Par ailleurs, l'enveloppe extérieure 27 présente une jupe intérieure tubulaire autour du corps de pompe 29 apte venir en contact étanche avec le pourtour intérieur de la seconde jupe d'étanchéité 22 de la pièce intermédiaire 3.Preferably, the dispensing member 26 is sealingly mounted on the container 2. In particular, a cup 33 surrounding the pump body 29 is sealingly retained inside the outer shell 27. Furthermore, the outer casing 27 has a tubular inner skirt around the pump body 29 adapted to come into sealing contact with the inner periphery of the second sealing skirt 22 of the intermediate piece 3.

L'organe de distribution 26 est monté de manière amovible sur le récipient 2. Ainsi lorsque le récipient 2 est vide et que l'intégralité du mélange a été distribuée, l'organe de distribution 26 peut être détaché pour être ultérieurement monté sur un autre dispositif tel que 1.The dispensing member 26 is removably mounted on the container 2. Thus, when the container 2 is empty and the entire mixture has been dispensed, the dispensing member 26 can be detached for later mounting on another device such as 1.

En effet, le produit P2 est déposé dans la chambre 5, l'organe de fermeture 4 étant disposé de telle sorte que le fond 7 repose sur une surface plane. Ensuite, la pièce intermédiaire 3 est vissée sur l'organe de fermeture 4 de manière à obturer la chambre 5. Dès lorsque cette chambre 5 est obturée, l'organe de fermeture 4 et la pièce intermédiaire 3 forment une unité étanche qui peut être manipulée sans risque de fuite. Le premier produit P1 est alors introduit dans le récipient 2, et l'unité étanche est alors claquée sur le col 9 du récipient 2 pour l'obturer. Le dispositif 1 selon l'invention est alors constitué, il est dans sa première configuration.The method of manufacturing a device 1 is simple, and allows at any time to ensure the separation between the products P1 and P2. Indeed, the product P2 is deposited in the chamber 5, the closure member 4 being arranged so that the bottom 7 rests on a flat surface. Then, the intermediate piece 3 is screwed on the closure member 4 so as to close the chamber 5. As soon as this chamber 5 is closed, the closure member 4 and the intermediate piece 3 form a sealed unit that can be handled without risk of leakage. The first product P1 is then introduced into the container 2, and the sealed unit is then slammed on the neck 9 of the container 2 to close it. The device 1 according to the invention is then constituted, it is in its first configuration.

De préférence, on utilise le dispositif 1 pour conditionner deux produits aptes à former ensemble une composition cosmétique et en particulier de traitement capillaire.Preferably, the device 1 is used to package two products capable of forming together a cosmetic composition and in particular of a hair treatment.
