Abstract

The holder (1) consists of first and second supple containers (2, 2') attached to a plate (10) equipped with a mobile distributor (30) that can be switched from a position in which the containers are isolated from the distributor outlet (32) to a position in which they are both connected to it. The movement of the distributor opens two plugs (59, 59') separating the containers from the outlet, with a tamper-proof ring (31) preventing the distributor from being opened without it showing.

Description

La présente invention a trait à un ensemble pour le conditionnement séparé de deux produits et pour leur distribution conjointe, en vue de réaliser une composition, notamment cosmétique, telle qu'utilisée par exemple dans le domaine de la coloration capillaire. D'autres applications toutefois peuvent être envisagées.The present invention relates to an assembly for the separate packaging of two products and for their joint distribution, with a view to producing a composition, in particular a cosmetic composition, as used for example in the field of hair dyeing. Other applications however can be envisaged.

Dans le domaine de la coloration capillaire, la préparation de bon nombre de compositions de coloration implique le mélange extemporané de deux produits (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 coloring, the preparation of a large number of coloring compositions involves the extemporaneous mixing of two products (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. L'étanchéité entre les deux compartiments contenant chacun des produits, est parfois difficile à réaliser. En outre, il est parfois difficile de trouver des matériaux, compatibles avec les composés 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 tightness between the two compartments containing each product, is sometimes difficult to achieve. In addition, it is sometimes difficult to find materials compatible with the compounds to be packaged, because of the high aggressiveness of at least some of the latter.

Il existe également des systèmes d'un fonctionnement plus "manuel" dans lesquels chacun des produits à mélanger est conditionné dans un conditionnement qui lui est propre, notamment sous forme d'un tube ou d'un sachet. En vue de la réalisation du mélange, le consommateur verse le contenu de l'un des conditionnements dans l'autre, ou le contenu des deux conditionnements dans un troisième, à l'intérieur duquel le mélange est réalisé.There are also systems of a more "manual" operation in which each of the products to be mixed is packaged in a packaging of its own, in particular in the form of a tube or a bag. In order to achieve mixing, the consumer pours the contents of one of the packages into the other, or the contents of the two packages in a third, within which the mixture is made.

US 6 065 643 décrit un système à deux tubes de l'art antérieur, correspondant au préambule de la revendication 1 annexée. Toutes ces opérations sont fastidieuses. Le risque est grand de se salir lors de la manipulation des produits. Le risque est grand également pour que le consommateur ne respecte pas le bon dosage et soit tenté d'utilisé les quantités nécessaires à une seule application pour deux ou plusieurs applications. Il en résulte alors une coloration des cheveux qui n'est pas conforme à celle attendue.US 6,065,643 discloses a two-tube system of the prior art, corresponding to the preamble of appended claim 1. All these operations are tedious. The risk is great to get dirty when handling products. The risk is also great for the consumer does not respect the correct dosage and is tempted to use the quantities needed for a single application for two or more applications. This results in hair coloring that does not conform to that expected.

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-avant en référence aux systèmes conventionnels discutés ci-avant.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 with reference to the conventional systems discussed above. .

C'est en particulier un objet de l'invention que de réaliser un tel dispositif qui soit simple à utiliser et qui puisse être produit à faible coût de revient.It is particularly an object of the invention to provide such a device which is simple to use and can be produced at low cost.

C'est un autre objet de l'invention que de réaliser un tel dispositif qui limite les risques de mauvaise utilisation, et qui de ce fait, réduit les risques d'obtenir un mélange dont les propriétés ne sont pas conformes à ce qui est attendu.It is another object of the invention to provide such a device which limits the risks of misuse, and which thereby reduces the risks of obtaining a mixture whose properties do not conform to what is expected. .

D'autres objets encore apparaîtront dans la description détaillée qui suit.Still other objects will appear in the following detailed description.

Selon l'invention, ces objets sont atteints en réalisant un dispositif pour la distribution conjointe de premier et second produits conditionnés séparément, comprenant :

  • a) un premier récipient à parois souples contenant le premier produit ;
  • b) un second récipient à parois souples, extérieur au premier, et contenant le second produit ;
  • c) une platine sur laquelle sont montés les premier et second récipients ;
  • d) un organe de distribution, mobile par rapport à la platine, et apte à faire passer le dispositif, de manière irréversible, d'une première configuration dans laquelle les premier et second récipients sont isolés d'au moins un orifice de distribution formé par ledit organe de distribution, à une seconde configuration dans laquelle les premier et second récipients sont en communication avec ledit (ou lesdits) orifice(s) de distribution.
According to the invention, these objects are achieved by providing a device for the joint distribution of first and second separately packaged products, comprising:
  • a) a first soft-walled container containing the first product;
  • b) a second flexible-walled container, external to the first, and containing the second product;
  • c) a plate on which are mounted the first and second containers;
  • d) a dispensing member movable with respect to the plate and able to pass the device irreversibly from a first configuration in which the first and second containers are isolated from at least one dispensing orifice formed by said dispensing member, in a second configuration in which the first and second containers are in communication with said (or said) orifice (s) distribution.

Ainsi, dans la seconde configuration du dispositif, en réponse à une pression exercée sur les parois souples des premier et second récipients, lesquels sont disposés de manière adjacente l'un par rapport à l'autre, les premier et second produits peuvent être distribués conjointement.Thus, in the second configuration of the device, in response to pressure exerted on the flexible walls of the first and second containers, which are arranged adjacent to each other, the first and second products can be distributed together.

La sortie conjointe des deux produits en vue de la réalisation d'une composition, notamment cosmétique, peut se faire via un orifice de distribution unique, en amont duquel peut se trouver une zone de mélange dans laquelle les deux produits sont mis en contact avant d'être distribués sous forme mélangée.The joint output of the two products for the production of a composition, especially a cosmetic composition, can be done via a single dispensing orifice, upstream of which there may be a mixing zone in which the two products are brought into contact beforehand. to be distributed in mixed form.

De préférence, le terme "irréversible" traduit le fait que le retour de la seconde configuration à la première est rendu impossible quelque soit la manipulation de l'organe de distribution, étant entendu que, bien qu'il ne soit pas impossible de faire parcourir à l'organe de distribution le mouvement inverse de celui qui a permis le passage du dispositif de la première configuration à la seconde, ce mouvement inverse sera sans effet sur la communication entre les récipients et l'orifice de distribution, et ne causera donc pas le retour du dispositif dans la première configuration.Preferably, the term "irreversible" reflects the fact that the return of the second configuration to the first is made impossible whatever the handling of the dispenser member, it being understood that, although it is not impossible to make travel to the dispensing member the reverse movement of the one that allowed the passage of the device from the first configuration to the second, this reverse movement will have no effect on the communication between the containers and the dispensing orifice, and therefore will not cause the return of the device in the first configuration.

Alternativement, les produits sortent via deux orifices de distribution disposés l'un à côté de l'autre, la mise en contact des deux produits se faisant, directement sur la surface à traiter dans le cas où l'organe de distribution est utilisé comme un embout d'application, ou dans un récipient auxiliaire dans lequel le mélange peut être homogénéisé de façon manuelle. Le choix de telle ou telle configuration dépend en particulier de la viscosité des produits et de leur capacité à se mélanger rapidement ou non.Alternatively, the products exit via two dispensing orifices arranged next to each other, the bringing into contact of the two products being done directly on the surface to be treated in the case where the dispenser member is used as a applicator tip, or in an auxiliary container in which the mixture can be homogenized manually. The choice of this or that configuration depends in particular on the viscosity of the products and their ability to mix quickly or not.

La fait que le passage de la première configuration à la seconde soit irréversible réduit le risque de voir le consommateur n'utiliser qu'une partie du contenu du dispositif. En effet, une fois que le dispositif est dans la seconde configuration, il est difficile d'envisager que le dispositif soit conservé en vue d'être utilisé autrement que dans le cadre d'une utilisation unique.The fact that the transition from the first configuration to the second is irreversible reduces the risk of the consumer using only part of the content of the device. Indeed, once the device is in the second configuration, it is difficult to envisage that the device is kept for use other than in the context of a single use.

La platine unique sur laquelle sont montés les deux récipients, permet, par un mouvement simple de l'organe de distribution relativement à la platine, notamment d'enfoncement axial ou de rotation, d'ouvrir du même coup les deux récipients. La gestuelle s'en trouve donc grandement simplifiée.The single plate on which the two containers are mounted allows, by a simple movement of the dispensing member relative to the plate, in particular axial depression or rotation, to open at the same time the two containers. The gesture is therefore greatly simplified.

De préférence, les deux récipients, notamment lorsqu'ils sont sous forme de sachets, formés par la réunion de deux feuilles soudées le long de leurs bords périphériques, sont disposés avec une première face principale du premier sachet au contact (ou sensiblement au contact) d'une seconde face principale de l'autre sachet. Les première et seconde faces peuvent être directement en regard l'une de l'autre, ou séparées par un moyen de séparation sous forme d'une plaque de faible épaisseur.Preferably, the two containers, especially when they are in the form of sachets, formed by the joining of two sheets welded along their peripheral edges, are arranged with a first main face of the first bag in contact (or substantially in contact) a second main face of the other bag. The first and second faces may be directly opposite one another, or separated by a separation means in the form of a thin plate.

En vue de la distribution conjointe des deux produits, il suffit d'exercer une pression simultanée sur les parois souples des deux récipients, de manière à forcer la sortie conjointe des deux produits au travers du ou des orifices de distribution.For the joint distribution of the two products, it is sufficient to exert simultaneous pressure on the flexible walls of the two containers, so as to force the joint outlet of the two products through the or orifices of distribution.

A cet effet, la platine est de préférence configurée de telle sorte que les récipients, notamment lorsqu'ils sont sous forme de sachets de relativement faible épaisseur, soient superposés de telle manière que, de préférence d'une seule main, les deux sachets puissent être comprimés en vue de provoquer l'expulsion de leur contenu.For this purpose, the plate is preferably configured so that the containers, especially when they are in the form of bags of relatively small thickness, are superimposed so that, preferably with one hand, the two bags can be compressed to cause the expulsion of their contents.

Alternativement, des moyens, notamment sous forme de deux plaques, disposées de part et d'autre des deux sachets superposés, peuvent être utilisés pour faciliter l'expulsion conjointe des deux produits contenus dans chacun des récipients. De telles plaques sont de préférence, de dimensions voisines de celles des sachets.Alternatively, means, in particular in the form of two plates, arranged on either side of the two superposed bags, can be used to facilitate the joint expulsion of the two products contained in each of the containers. Such plates are preferably of dimensions close to those of the bags.

Avantageusement, l'organe de distribution comporte des première et seconde portions d'ouverture, aptes, en réponse à un mouvement, notamment axial, de l'organe de distribution relativement à la platine, à venir en engagement avec des éléments de fermeture, situés bien en amont du (ou des) orifice(s) de distribution, et associés à des passages d'entrée/sortie des premier et second récipients, de manière à mettre ces derniers en communication fluide le (ou les) orifice(s) de distribution, ladite mise en engagement étant unidirectionnelle.Advantageously, the dispensing member comprises first and second opening portions, adapted, in response to a movement, in particular axial movement, of the dispensing member relative to the plate, to come into engagement with closure elements, located well before the (or) orifice (s) of distribution, and associated with inlet / outlet passages of the first and second containers, so as to put them in fluid communication the (or) orifice (s) of distribution, said engagement being unidirectional.

Ainsi, la mise en engagement des portions d'ouverture avec les éléments de fermeture, résulte par exemple d'un enfoncement de l'organe de distribution par rapport à la platine. En supposant qu'un mouvement de sens inverse soit possible de l'organe de distribution par rapport à la platine, alors un tel mouvement serait sans effet sur les éléments de fermeture puisque l'engagement n'est qu'unidirectionnel.Thus, the engagement of the opening portions with the closure elements, for example results from a depression of the dispensing member relative to the plate. Assuming that a movement in the opposite direction is possible of the dispensing member with respect to the plate, then such a movement would have no effect on the closure elements since the engagement is only one-way.

De préférence, les première (respectivement seconde) portions d'ouverture sont constituées de l'extrémité libre de premier (respectivement second) éléments tubulaires formés par l'organe de distribution et communiquant avec le (ou les) orifice(s) de distribution.Preferably, the first (respectively second) opening portions consist of the free end of first (respectively second) tubular elements formed by the dispensing member and communicating with the (or) orifice (s) distribution.

De telles portions tubulaires sont de longueur suffisante pour venir en engagement avec lesdits éléments de fermeture, lesquels sont, de préférence, disposés à l'intérieur de leurs récipients respectifs.Such tubular portions are of sufficient length to engage with said closure members, which are preferably disposed within their respective containers.

Avantageusement, l'extrémité libre des premier et second éléments tubulaires est crénelée de manière à favoriser la communication entre les premier (respectivement second) récipients et le (ou les) orifice(s) de distribution lorsque le dispositif est dans la seconde configuration. Cette caractéristique est avantageuse notamment lorsque, comme nous le verrons en détail par la suite, les éléments de fermeture sont couplés à des bandes de liaison dont l'élasticité intrinsèque à tendance à les ramener dans une position correspondant à la première configuration du dispositif.Advantageously, the free end of the first and second tubular elements is crenated so as to promote communication between the first (respectively second) containers and the (or) orifice (s) distribution when the device is in the second configuration. This characteristic is advantageous especially when, as we shall see in detail later, the closure elements are coupled to binding strips whose intrinsic elasticity tends to bring them back to a position corresponding to the first configuration of the device.

L'organe de distribution peut comprendre des moyens de verrouillage aptes à coopérer avec des moyens correspondants de la platine pour immobiliser au moins axialement, l'organe de distribution relativement à la platine lorsque le dispositif est dans la seconde configuration. Cette solution est avantageuse dans la mesure où elle constitue l'un des moyens pouvant être mis en oeuvre pour assurer l'irréversibilité du passage du dispositif de la première à la seconde configuration. Elle est également avantageuse lorsque ledit caractère irréversible est assuré par une mise en engagement unidirectionnelle des portions d'ouverture de l'organe de distribution et des éléments de fermeture. En effet, sans un tel verrouillage, l'organe de distribution pourrait être désolidarisé du reste du dispositif, et risquerait de rendre difficile la manipulation du dispositif en vue de la distribution conjointe des deux produits.The dispensing member may comprise locking means adapted to cooperate with corresponding means of the plate to immobilize at least axially, the dispensing member relative to the plate when the device is in the second configuration. This solution is advantageous insofar as it is one of the means that can be implemented to ensure the irreversibility of the passage of the device from the first to the second configuration. It is also advantageous when said irreversible character is ensured by unidirectional engagement of the opening portions of the dispensing member and the closure elements. Indeed, without such locking, the dispenser member could be detached from the rest of the device, and could make it difficult to manipulate the device for the joint distribution of the two products.

De préférence, le dispositif comprend un indicateur d'effraction constitué d'un élément non repositionnable, notamment sous forme d'une bande arrachable. Ainsi, tant que l'indicateur d'effraction n'a pas été enlevé, l'organe de distribution ne peut être déplacé par rapport à la platine en vue de l'ouverture des deux récipients.Preferably, the device comprises a burglar indicator consisting of a non-repositionable element, in particular in the form of a strippable strip. Thus, as the tamper indicator has not been removed, the dispenser member can not be moved relative to the platen for opening the two containers.

Avantageusement, les éléments de fermeture associés aux passages d'entrée/sortie des premier et second récipients comportent un moyen de couplage apte à coopérer, notamment par encliquetage, avec des moyens correspondants d'un outil apte, avant la mise en place de l'organe de distribution, à entraîner les premier et second éléments de fermeture depuis leur position dans laquelle les premier et second récipients communiquent avec l'extérieur, vers leur position dans laquelle ils isolent les premier et second récipients de l'extérieur. Ainsi, lorsque le remplissage des récipients est effectué via les passages d'entrée/sortie, ces moyens de couplage rendent possible, après le remplissage, la fermeture desdits passages par lesdits éléments de fermeture avant de mettre en place l'organe de distribution.Advantageously, the closure elements associated with the inlet / outlet passages of the first and second containers comprise a coupling means adapted to cooperate, in particular by snapping, with corresponding means of a suitable tool, before the introduction of the dispensing member, driving the first and second closure members from their position in which the first and second containers communicate with the outside, to their position in which they isolate the first and second containers from the outside. Thus, when the filling of the containers is performed via the inlet / outlet passages, these coupling means make it possible, after filling, closing said passages by said closure elements before setting up the dispenser member.

De préférence, l'outil est constitué d'une canne de remplissage dont une portion au moins est apte à être introduite dans les passages d'entrée/sortie des récipients, de manière à les remplir. Dans l'hypothèse où avant remplissage, les premier et second récipients sont isolés de l'extérieur par les éléments de fermeture, la canne de remplissage peut être utilisée lors de son introduction pour venir en engagement avec les éléments de fermeture de manière à les chasser en vue de mettre les premier et second récipients en communication avec l'extérieur. Après remplissage, la canne de remplissage, lors de son mouvement de retrait, entraîne les éléments de fermeture dans la position où ils isolent les premier et second récipients de l'extérieur.Preferably, the tool consists of a filling rod of which at least a portion is adapted to be introduced into the inlet / outlet passages of the containers, so as to fill them. In the event that before filling, the first and second containers are isolated from the outside by the closure elements, the filling rod can be used during its introduction to engage with the closure elements so as to chase them in order to put the first and second containers in communication with the outside. After filling, the filling rod, during its withdrawal movement, causes the closure elements in the position where they isolate the first and second containers from the outside.

De préférence, lesdits premier et second récipients sont configurés sous forme de sachets dont les parois sont formés d'au moins une couche d'un matériau thermoplastique ou métallique. De tels sachets sont généralement de forme sensiblement rectangulaire. A titre indicatif, leur longueur peut être de l'ordre de 10 cm. Leur largeur peut être de l'ordre de 5 cm.Preferably, said first and second containers are configured in the form of bags whose walls are formed of at least one layer of a thermoplastic or metal material. Such bags are generally of substantially rectangular shape. As an indication, their length may be of the order of 10 cm. Their width can be of the order of 5 cm.

Avantageusement, les passages d'entrée/sortie desdits premier et second récipients ainsi que leurs éléments de fermeture associés sont formés par des premier et second inserts montés, notamment par encliquetage, sur ladite platine. De tels inserts sont décrits notamment dans la demande WO/9905446.Advantageously, the inlet / outlet passages of said first and second containers and their associated closure elements are formed by first and second inserts mounted, in particular by snapping, on said plate. Such inserts are described in particular in the application WO / 9905446.

De préférence, les éléments de fermeture associés aux passages d'entrée/sortie des premier et second récipients sont reliés à leur insert respectif par au moins deux bandes de liaison souples. Ces bandes de liaison sont avantageuses lors du remplissage où il est souhaitable de pouvoir, avant remplissage, enlever les éléments de fermeture puis de pouvoir les remettre en position après remplissage.Preferably, the closure elements associated with the inlet / outlet passages of the first and second containers are connected to their respective insert by at least two flexible connecting strips. These binding strips are advantageous during filling where it is desirable to be able, before filling, to remove the closure elements and then to be able to return them to position after filling.

Les premier et second récipients peuvent être montés sur les premier, respectivement second, inserts, notamment par collage ou soudure.The first and second containers may be mounted on the first, respectively second, inserts, especially by gluing or welding.

Le premier produit peut être un colorant, le second produit pouvant être un oxydant, ladite composition à réaliser à l'issu du mélange étant une composition de coloration capillaire.The first product may be a dye, the second product may be an oxidant, said composition to be produced at the end of the mixture being a hair dye composition.

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

The invention consists, apart from the arrangements described 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 shows a perspective view of a device according to a preferred embodiment of the invention;

  • FIGS. 6A-6C illustrate the various steps to be implemented when using the device of FIGS. 1 and 2.

D'une manière générale, le dispositif 1 d'axe X, représenté dans les vues en perspective des figures 1 et 2 et dans les vues en coupe des figures 3A-3B et 4A-4B comprend deux sachets identiques 2, 2', disposés l'un à côté de l'autre et montés sur une platine 10.In general, the X-axis device 1, shown in the perspective views of FIGS. 1 and 2 and in the sectional views of FIGS. 3A-3B and 4A-4B, comprises two identical bags 2, 2 'arranged one next to the other and mounted on a turntable 10.

Le premier sachet 2 contient un colorant d'oxydation. Le second sachet 2' contient un oxydant.The first bag 2 contains an oxidation dye. The second bag 2 'contains an oxidant.

Sur la platine 10 est disposé un organe de distribution 30 comportant une bande d'inviolabilité 31 à enlever avant la première utilisation. L'organe de distribution 30 comporte un orifice de distribution 32 de section transversale allongée.On the plate 10 is disposed a dispensing member 30 having a tamper band 31 to be removed before the first use. The dispensing member 30 has a dispensing orifice 32 of elongate cross-section.

Les sachets 2 et 2' sont formés par superposition de deux feuilles identiques et par soudure desdites feuilles le long de leur fond et de leurs deux bords longitudinaux. L'extrémité opposée au fond de chacun des sachets est fermée par un insert 50, 50', lequel peut être collé ou soudé entre les deux feuilles définissant chacun des sachets 2 et 2'. Les feuilles formant les sachets peuvent être formées à partir d'un complexe d'aluminium et d'un matériau plastique, thermosoudable avec lui même.The bags 2 and 2 'are formed by superposition of two identical sheets and by welding said sheets along their bottom and their two longitudinal edges. The end opposite the bottom of each of the bags is closed by an insert 50, 50 ', which can be glued or welded between the two sheets defining each of the bags 2 and 2'. The sheets forming the bags can be formed from an aluminum complex and a plastic material, heat-sealable with itself.

L'insert 50 est réalisé en une seule pièce thermoplastique, obtenue par injection moulage.The insert 50 is made of a single thermoplastic part, obtained by injection molding.

L'insert 50 comprend une jupe cylindrique 51 à l'intérieur de laquelle est formé un passage axial 52. La surface extérieure de la jupe cylindrique 51, au voisinage de l'extrémité supérieure de l'insert 50 comprend un bourrelet d'accrochage 53. Tout autour de la jupe cylindrique 51, sensiblement au niveau du quart supérieur de la hauteur de l'insert 50, est formée une paroi transversale 54 de forme rectangulaire avec deux extrémités arrondies. Sous la paroi 54, la jupe cylindrique 51 se raccorde à deux ailes 55, 56, disposées dans un même plan contenant l'axe longitudinal de l'insert 50. L'épaisseur des ailes 55 et 56 diminue progressivement en direction de leur extrémité opposée à la jupe 51.The insert 50 comprises a cylindrical skirt 51 inside which is formed an axial passage 52. The outer surface of the cylindrical skirt 51, in the vicinity of the upper end of the insert 50 comprises a fastening bead 53 All around the cylindrical skirt 51, substantially at the upper quarter of the height of the insert 50 is formed a transverse wall 54 of rectangular shape with two rounded ends. Under the wall 54, the cylindrical skirt 51 is connected to two wings 55, 56, arranged in the same plane containing the longitudinal axis of the insert 50. The thickness of the wings 55 and 56 gradually decreases toward their opposite end. at the skirt 51.

Au voisinage de son extrémité inférieure, la jupe cylindrique 51 est de section plus faible, et comprend sur sa surface intérieure une gorge annulaire 57 apte à coopérer par encliquetage avec un bourrelet annulaire 58 formé sur la surface extérieure d'un bouchon creux 59 destiné à s'insérer à l'intérieur du passage axial 52 de manière à l'obturer. La surface interne du bouchon comporte également une gorge annulaire 60 dont la fonction sera explicitée en détail par la suite. Le bouchon est relié par deux bandes de liaison souples 61 et 62 à chacune des ailes 55 et 56 de l'insert.In the vicinity of its lower end, the cylindrical skirt 51 is of smaller section, and comprises on its inner surface an annular groove 57 adapted to snap cooperating with an annular bead 58 formed on the outer surface of a hollow plug 59 intended for insert inside the axial passage 52 so as to close it. The inner surface of the cap also has an annular groove 60 whose function will be explained in detail later. The plug is connected by two flexible connecting strips 61 and 62 to each of the wings 55 and 56 of the insert.

L'insert 50' est identique à l'insert 50 et de ce fait, sa description ne sera pas reprise. Les références numériques affectées à l'insert 50' sont celles affectées à l'insert 50 auxquelles on a rajouté un "prime".The insert 50 'is identical to the insert 50 and therefore, its description will not be repeated. The numerical references assigned to the insert 50 'are those assigned to the insert 50 to which a "prime" has been added.

Une vue en coupe des inserts (dans leur position fermée) est représentée à la figure 3B. Une vue en coupe des inserts (dans leur position ouverte) est représentée à la figure 4B.A sectional view of the inserts (in their closed position) is shown in Figure 3B. A sectional view of the inserts (in their open position) is shown in Figure 4B.

A la figure 2 également, les inserts 50 et 50' sont représentés dans leur position d'ouverture.In Figure 2 also, the inserts 50 and 50 'are shown in their open position.

La platine 10, de section transversale sensiblement rectangulaire, comprend une paroi transversale 11 sur une surface de laquelle sont ménagés deux renfoncements 12 et 13 de forme correspondant à la forme des parois transversales 54 et 54' des inserts 50 et 50'. La paroi 11 est traversée au centre de chacun des renfoncements 12 et 13 par un passage 14 et 15 délimité par quatre portions de jupes 16 en arc de cercle dont la surface intérieure forme, à l'opposé de la paroi 11, un bourrelet d'accrochage 17 apte à coopérer par encliquetage avec les bourrelets 53 et 53' des inserts 50 et 50'.The plate 10, of substantially rectangular cross section, comprises a transverse wall 11 on a surface of which are formed two recesses 12 and 13 of shape corresponding to the shape of the transverse walls 54 and 54 'of the inserts 50 and 50'. The wall 11 is traversed in the center of each of the recesses 12 and 13 by a passage 14 and 15 delimited by four portions of skirts 16 in an arc whose inner surface forms, opposite the wall 11, a bead of hooking 17 adapted to cooperate by snapping with the beads 53 and 53 'of the inserts 50 and 50'.

Du côté des passages 14 et 15, la paroi transversale 11 de la platine 10 est bordée par quatre portions de jupe 18 qui, comme on le verra par la suite, servent à l'accrochage d'un organe de distribution 30. A cet effet, chaque portion de jupe 18 comprend sur sa surface extérieure un premier bourrelet d'encliquetage 19 adjacent à la paroi transversale 11 et un second bourrelet d'encliquetage 20 disposé au voisinage du bord libre des portions de jupe 18.On the side of the passages 14 and 15, the transverse wall 11 of the plate 10 is bordered by four skirt portions 18 which, as will be seen later, are used for the attachment of a dispenser member 30. For this purpose each skirt portion 18 comprises on its outer surface a first snap-fitting bead 19 adjacent to the transverse wall 11 and a second snap-fitting bead 20 disposed in the vicinity of the free edge of the skirt portions 18.

Sur sa surface tournée à l'opposé des passages 14 et 15, la paroi transversale 11 comprend, centrées sur le grand axe de sa section transversale, deux zones rainurées 21 et 22 dont la fonction sera expliquée en détail par la suite.On its surface turned away from the passages 14 and 15, the transverse wall 11 comprises, centered on the major axis of its cross section, two grooved zones 21 and 22 whose function will be explained in detail later.

La platine 10 est également obtenue de moulage par injection d'un matériau thermoplastique.Platen 10 is also obtained by injection molding a thermoplastic material.

L'organe de distribution 30 est de section transversale, au voisinage de sa base, similaire à la section transversale de la platine 10. Sensiblement à mi hauteur, l'organe de distribution 30 forme deux épaulements 33 et 34 centrés sur le grand axe de la section transversale de sa base rectangulaire. La surface extérieure des épaulements 33 et 34 est nervurée. Au delà des épaulements 33 et 34, la section transversale de l'organe de distribution 30 diminue progressivement en direction de l'orifice de distribution 32.The dispensing member 30 is of transverse section, in the vicinity of its base, similar to the cross section of the plate 10. At substantially mid-height, the dispensing member 30 forms two shoulders 33 and 34 centered on the major axis of the cross section of its rectangular base. The outer surface of the shoulders 33 and 34 is ribbed. Beyond the shoulders 33 and 34, the cross section of the dispensing member 30 gradually decreases towards the dispensing orifice 32.

A l'opposé de l'orifice de distribution 32, l'organe de distribution 30 est relié à une bande d'inviolabilité 31 de section transversale similaire à la section transversale de la platine 10.Opposite the dispensing orifice 32, the dispensing member 30 is connected to a tamper-evident band 31 of cross section similar to the cross section of the plate 10.

L'orifice de distribution 32 communique avec une première extrémité de deux éléments tubulaires 35, 36 alignés selon le petit axe de la section transversale de la base de l'organe de distribution 30.The dispensing orifice 32 communicates with a first end of two tubular elements 35, 36 aligned along the minor axis of the cross section of the base of the dispensing member 30.

L'extrémité libre des éléments tubulaires 35 et 36 présente un bord crénelé 37 et 38. La section externe des éléments tubulaires 35 et 36, ainsi que leur longueur, sont telles qu'ils puissent s'introduire à l'intérieur des passages 52 et 52' des inserts 50 et 50' et que leurs bords crénelés 37 et 38, après enlèvement de la bande d'inviolabilité 31, puissent venir en engagement avec le bord supérieur des bouchons 59 et 59' de manière à dégager les passages 52 et 52'.The free end of the tubular elements 35 and 36 has a crenellated edge 37 and 38. The outer section of the tubular elements 35 and 36, as well as their length, are such that they can be introduced inside the passages 52 and 52 'of inserts 50 and 50 'and that their serrated edges 37 and 38, after removal of the tamper band 31, can come into engagement with the upper edge of the plugs 59 and 59' so as to clear the passages 52 and 52 '.

La surface intérieure de la paroi latérale de l'organe de distribution 30, comprend au voisinage de son bord adjacent à la bande d'inviolabilité 31, un bourrelet périphérique 39 apte, comme on peut le voir sur la figure 3A, à coopérer par encliquetage avec le bourrelet périphérique 20 de la platine 10 avant l'enlèvement de la bande d'inviolabilité. Dans cette configuration, un bourrelet 40 formé au voisinage du bord inférieur de la bande d'inviolabilité 31 est en engagement par encliquetage avec le bourrelet 19 de la platine.The inner surface of the side wall of the dispensing member 30 comprises, in the vicinity of its edge adjacent to the tamper-evident band 31, a peripheral bead 39 adapted, as can be seen in FIG. 3A, to cooperate by snapping-in. with the peripheral bead 20 of the plate 10 before removal of the tamper-evident band. In this configuration, a bead 40 formed in the vicinity of the lower edge of the tamper-evident band 31 is in snap engagement with the bead 19 of the plate.

Comme on le voit sur la figure 4A, après avoir au préalable arraché la bande d'inviolabilité 31, une pression exercée axialement sur l'organe de distribution 30 provoque un mouvement axial de ce dernier et la mise en engagement du bourrelet 39 de l'organe de distribution 30 avec le bourrelet 19 de la platine 10. De préférence, la force d'accrochage entre les bourrelets 39 et 19 est telle que, sauf à exercer une force sans commune mesure avec des conditions normales d'utilisation, l'encliquetage entre les bourrelets 39 et 19 ne puisse être décroché.As can be seen in FIG. 4A, after having previously torn off the tamper evident band 31, a pressure exerted axially on the dispensing member 30 causes an axial movement of the latter and the engagement of the bead 39 of the dispensing member 30 with the bead 19 of the plate 10. Preferably, the gripping force between the beads 39 and 19 is such that, except to exert a force incommensurate with normal conditions of use, snapping between the beads 39 and 19 can not be unhooked.

Une vue en coupe du dispositif 1 en position de fermeture est représentée à la figure 3A. Dans cette position, l'insert 50 (ainsi que 50') est tel que représenté à la figure 3B.A sectional view of the device 1 in the closed position is shown in Figure 3A. In this position, the insert 50 (as well as 50 ') is as shown in Figure 3B.

Une vue en coupe du dispositif en position de distribution est représentée à la figure 4A. Dans cette position, l'insert 50 (ainsi que 50') est tel que représenté à la figure 4B.A sectional view of the device in the dispensing position is shown in FIG. 4A. In this position, the insert 50 (and 50 ') is as shown in Figure 4B.

Les figures 5A-5E auxquelles il est maintenant fait référence illustrent les principales étapes de remplissage du dispositif qui vient d'être décrit en référence aux figures précédentes.FIGS. 5A-5E, to which reference is now made, illustrate the main filling steps of the device which has just been described with reference to the preceding figures.

A la figure 5A, les sachets 2 et 2' équipés de leurs inserts 50 et 50' sont montés sur la platine 10. A ce stade, les inserts 50 et 50' sont dans la configuration de la figure 3B dans laquelle les bouchons 59 et 59' obturent les extrémités inférieures des passages 52 et 52'. Ces derniers ne communiquent donc pas avec les sachets 2 et 2'.In FIG. 5A, the sachets 2 and 2 'equipped with their inserts 50 and 50' are mounted on the plate 10. At this stage, the inserts 50 and 50 'are in the configuration of the Figure 3B in which the plugs 59 and 59 'seal the lower ends of the passages 52 and 52'. The latter do not communicate with the bags 2 and 2 '.

A la figure 5B, un outil de remplissage 80 comprenant deux cannes tubulaires 83, 84 maintenues à distance adéquate l'une de l'autre par un séparateur 85, est mis en engagement avec le dispositif 1. Lors de cette mise en engagement, les cannes 83 et 84 sont introduites dans les passages 52 et 52' jusqu'à ce que la tête des cannes de remplissage s'engage dans les bouchons 59 et 59'. A ce moment, un bourrelet 81, 82 formé par les cannes de remplissage s'engage par encliquetage avec les gorges 60 et 60' des bouchons 59 et 59'.In FIG. 5B, a filling tool 80 comprising two tubular rods 83, 84 held at a suitable distance from each other by a separator 85, is engaged with the device 1. During this engagement, the rods 83 and 84 are introduced into the passages 52 and 52 'until the head of the filling rods engages in the plugs 59 and 59'. At this moment, a bead 81, 82 formed by the filling rods snaps into engagement with the grooves 60 and 60 'of the plugs 59 and 59'.

En continuant d'exercer une pression axiale au moyen des cannes de remplissage, les bouchons 59 et 59' se désengagent des passages 52 et 52'. La communication est établie entre les cannes de remplissage 83 et 84 et les sachets 2 et 2'.By continuing to exert axial pressure by means of the filling rods, the plugs 59 and 59 'disengage passages 52 and 52'. The communication is established between the filling rods 83 and 84 and the bags 2 and 2 '.

A la figure 5C, les produits amenés via les cannes de remplissage 83 et 84 sont introduits dans les sachets 2 et 2', via les orifices 86 et 87 des cannes de remplissage 83 et 84, et ce, jusqu'à remplissage complet de ces derniers.In FIG. 5C, the products brought via the filling rods 83 and 84 are introduced into the bags 2 and 2 ', via the orifices 86 and 87 of the filling rods 83 and 84, and until these fill completely. last.

Après remplissage, les cannes de remplissage 83 et 84 sont retirées selon un mouvement axial dans la direction opposée aux sachets. Ce faisant, et en raison de l'encliquetage entre les bourrelets 81 et 82 des cannes de remplissage avec les gorges 60 et 60' des bouchons 59 et 59', ces derniers sont remontés jusqu'à s'insérer dans les passages 52 et 52' des inserts 50 et 50'. La communication est alors interrompue entre les passages 52, 52' et les sachets 2 et 2'. Cette position est illustrée à la figure 5D.After filling, the filling rods 83 and 84 are removed in an axial movement in the opposite direction to the bags. In doing so, and because of the snap between the beads 81 and 82 of the filling rods with the grooves 60 and 60 'of the plugs 59 and 59', the latter are reassembled to fit into the passages 52 and 52 inserts 50 and 50 '. The communication is then interrupted between the passages 52, 52 'and the bags 2 and 2'. This position is illustrated in Figure 5D.

A la figure 5E, l'organe de distribution 30 est monté sur la platine 10 par encliquetage des bourrelets 39 et 40 de l'organe de distribution 30 avec les bourrelets 19 et 20 de la platine 10.In FIG. 5E, the dispensing member 30 is mounted on the plate 10 by snapping the beads 39 and 40 of the dispensing member 30 with the beads 19 and 20 of the plate 10.

Les figures 6A-6C auxquelles il est maintenant fait référence, illustrent les étapes d'utilisation du dispositif 1 qui vient d'être décrit précédemment.FIGS. 6A-6C, to which reference is now made, illustrate the steps of using the device 1 which has just been described above.

A la figure 6A, la bande d'inviolabilité 31 de l'organe de distribution 30 est arrachée.In FIG. 6A, the tamper-evident band 31 of the dispensing member 30 is torn off.

A la figure 6B, en saisissant le dispositif des deux mains entre les zones nervurées 33, 34 de l'organe de distribution, et les zones nervurées 21, 22 de la platine 10, l'utilisateur provoque l'enfoncement de l'organe de distribution 30 jusqu'à ce que le bourrelet 39 vienne en engagement avec le bourrelet 19 de la platine 10.In FIG. 6B, by grasping the device with both hands between the ribbed zones 33, 34 of the dispensing member, and the ribbed zones 21, 22 of the plate 10, the user causes the depression of the distribution 30 until the bead 39 comes into engagement with the bead 19 of the plate 10.

Ce faisant, le bord crénelé 37 et 38 des portions tubulaires 35 et 36 de l'organe de distribution vient en butée contre le bord libre des bouchons 59 et 59', jusqu'à en provoquer le désengagement avec les passages 52 et 52'. La communication est ainsi établie entre l'orifice de distribution 32 et les sachets 2 et 2'. Cette configuration du dispositif correspond à celle représentée en coupe à la figure 4A.In doing so, the crenellated edge 37 and 38 of the tubular portions 35 and 36 of the dispenser member abuts against the free edge of the plugs 59 and 59 ', until it disengages with the passages 52 and 52'. The communication is thus established between the dispensing orifice 32 and the bags 2 and 2 '. This configuration of the device corresponds to that shown in section in Figure 4A.

Dans cette configuration, l'étanchéité annulaire entre la surface externe des portions tubulaires 35 et 36 de l'organe de distribution 30 et la paroi interne des passages d'entrée/sortie 52, 52' des sachets 2, 2' peut être assurée par un arrangement bourrelet/gorge.In this configuration, the annular seal between the outer surface of the tubular portions 35 and 36 of the dispensing member 30 and the inner wall of the inlet / outlet passages 52, 52 'of the bags 2, 2' can be provided by a bead / groove arrangement.

Le repositionnement des bouchons 59 et 59' dans leur position dans laquelle ils isolent les sachets 2 et 2' de l'orifice de distribution 32 est rendu impossible en raison de la mise en engagement unidirectionnelle des portions tubulaires 35 et 36 avec les bouchons 59 et 59'. En effet, même en supposant que l'utilisateur arrive à désencliqueter les bourrelets 39 de l'organe de distribution et 19 de la platine 10, alors l'organe de distribution 30 pourrait être retiré de la platine 10 sans toutefois provoquer le repositionnement des bouchons 59 et 59'.The repositioning of the plugs 59 and 59 'in their position in which they isolate the bags 2 and 2' from the dispensing orifice 32 is made impossible due to the unidirectional engagement of the tubular portions 35 and 36 with the plugs 59 and 59 '. Indeed, even assuming that the user manages to disengage the beads 39 of the dispenser member and 19 of the plate 10, then the dispenser member 30 could be removed from the plate 10 without causing the repositioning plugs 59 and 59 '.

A la figure 6C, l'utilisateur retourne le dispositif au dessus d'un récipient dans lequel le mélange est à effectuer, et pressurise les sachets 2 et 2' entre ses mains de manière à provoquer la sortie conjointe des deux produits au travers de l'orifice de distribution 32, via les portions tubulaires 35 et 36 de l'organe de distribution, et ce jusqu'à vidange complète du contenu des deux sachets.In FIG. 6C, the user turns the device over a container in which the mixture is to be made, and pressurizes the sachets 2 and 2 'between his hands so as to cause the two products to exit together through the 'orifice distribution 32, via the tubular portions 35 and 36 of the dispenser member, and until complete emptying of the contents of the two bags.

Alternativement, la distribution conjointe des deux produits se fait directement sur les cheveux ou sur les mèches à colorer, l'organe de distribution 30 étant utilisé comme embout d'application.Alternatively, the joint distribution of the two products is done directly on the hair or on the bits to be colored, the dispensing member 30 being used as an applicator tip.

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. En particulier, dans le mode de réalisation qui vient d'être décrit, les sachets 2 et 2' sont orientés parallèlement au plan contenant le grand axe de la section transversale de la platine 10. Selon une alternative, les sachets sont orientés parallèlement au plan contenant le petit axe de la section transversale de la platine 10. Cette alternative présente l'avantage de rendre plus facile la mise en mouvement de l'organe de distribution 30 en vue d'ouvrir les sachets 2 et 2'. Selon une autre alternative, la section transversale de la platine 10 ainsi que de la base de l'organe de distribution 30 est de forme autre que rectangulaire, notamment circulaire.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. In particular, in the embodiment just described, the bags 2 and 2 'are oriented parallel to the plane containing the major axis of the cross section of the plate 10. According to one alternative, the bags are oriented parallel to the plane containing the small axis of the cross section of the plate 10. This alternative has the advantage of making easier the setting in motion of the dispensing member 30 to open the bags 2 and 2 '. According to another alternative, the cross section of the plate 10 as well as the base of the dispensing member 30 is of other than rectangular shape, in particular circular.
