Description

L'invention est relative à un dispositif pour conserver séparés l'un de l'autre au moins deux produits et pour effectuer leur mélange à un instant souhaité, notamment au moment de l'utilisation, du genre de ceux qui comportent :

  • un premier récipient pour l'un des produits ;
  • au moins un deuxième récipient pour au moins un autre produit, les deux récipients étant assemblés de manière étanche vis-à-vis de l'extérieur, tout en ayant une possibilité de déplacement relatif,
  • et des moyens d'obturation propres à maintenir isolé le premier récipient du deuxième, ces moyens d'obturation pouvant être ouverts en réponse à un déplacement relatif approprié des récipients.
The invention relates to a device for keeping at least two products separated from one another and for mixing them at a desired time, in particular at the time of use, of the type of those which comprise:
  • a first container for one of the products;
  • at least a second container for at least one other product, the two containers being assembled in a sealed manner with respect to the outside, while having a possibility of relative displacement,
  • and closure means suitable for keeping the first container isolated from the second, said closure means being able to be opened in response to an appropriate relative movement of the containers.

FR-A-2 569 666 montre un dispositif de ce genre dans lequel les moyens d'obturation comprennent un opercule destiné à être déchiré lors du déplacement relatif des deux réservoirs, pour leur mise en communication. L'opercule, une fois déchiré, peut être gênant pour le bon écoulement des produits et du mélange. De plus, la perforation de l'opercule est obtenue par un déplacement axial relatif des réservoirs qui engendre une diminution du volume interne de l'ensemble du mélangeur. Or, un tel dispositif est souvent utilisé en vue du mélange d'un colorant contenu dans l'un des récipients et d'un oxydant contenu dans l'autre récipient pour réaliser une teinture capillaire ; lorsque le mélange est effectué, il se produit un léger dégagement gazeux et la diminution du volume interne contribue à un accroissement de la surpression, ce qui peut provoquer des projections du mélange lorsque le dispositif est ouvert sur l'extérieur, en vue de distribuer ce mélange.FR-A-2 569 666 shows a device of this kind in which the shutter means comprise a cover intended to be torn during the relative movement of the two tanks, for placing them in communication. The lid, once torn, can be troublesome for the proper flow of the products and the mixture. In addition, the perforation of the cover is obtained by a relative axial displacement of the tanks which generates a decrease in the internal volume of the entire mixer. However, such a device is often used for mixing a dye contained in one of the containers and an oxidant contained in the other container to produce a hair dye; when the mixing is carried out, a slight release of gas occurs and the reduction in the internal volume contributes to an increase in the overpressure, which can cause projections of the mixture when the device is open to the outside, in order to distribute this mixed.

Les documents JP-U-3-72634 et JP-U-3-72678, publiés le 23 juillet 1991, montrent un dispositif du genre défini précédemment dans lequel les moyens d'obturation comprennent un bouchon situé dans le volume interne, et qui est désolidarisé lors du déplacement relatif des deux réservoirs. Le déplacement axial des deux récipients, permettant d'ouvrir les moyens d'obturation, engendre une augmentation du volume interne de l'ensemble du mélangeur, mais le bouchon, une fois désolidarisé, constitue toujours une gêne au bon écoulement des produits ou du mélange soit au niveau de la communication des deux récipients, soit au niveau de l'orifice permettant la distribution du mélange vers l'extérieur.The documents JP-U-3-72634 and JP-U-3-72678, published on July 23, 1991, show a device of the kind defined above in which the sealing means comprise a plug located in the internal volume, and which is separated during the relative movement of the two tanks. The axial displacement of the two containers, making it possible to open the sealing means, generates an increase in the internal volume of the entire mixer, but the cap, once uncoupled, always constitutes an impediment to the good flow of the products or of the mixture either at the level of the communication of the two containers, or at the level of the orifice allowing the distribution of the mixture towards the outside.

FR-A-2 239 390 montre un dispositif du genre défini précédemment, dans lequel les moyens d'obturation comprennent un plateau obturateur lié à l'un des récipients, et une cloison de fermeture, munie d'un siège pour ledit plateau obturateur, l'ensemble étant tel qu'en position de fermeture, le plateau obturateur est appliqué de manière étanche contre le siège, tandis qu'un déplacement relatif approprié des deux récipients écarte le plateau du siège et assure l'ouverture des moyens d'obturation. Selon FR-A-2 239 390, le déplacement assurant l'ouverture des moyens d'obturation provoque une diminution du volume interne de l'ensemble, avec les inconvénients évoqués précédemment.FR-A-2 239 390 shows a device of the kind defined above, in which the shutter means comprise a shutter plate connected to one of the containers, and a closing partition, provided with a seat for said shutter plate, the assembly being such that in the closed position, the shutter plate is applied in leaktight manner against the seat, while an appropriate relative movement of the two containers separates the plate from the seat and ensures the opening of the shutter means. According to FR-A-2 239 390, the movement ensuring the opening of the closure means causes a reduction in the internal volume of the assembly, with the drawbacks mentioned above.

US-A-3 924 741 montre un dispositif selon la première partie de la revendication 1 dans lequel le déplacement des moyens d'obturation provoque une augmentation du volume interne de l'ensemble. Cependant, ce dispositif comporte des espaces morts ; il sera extrêmement difficile d'évacuer de ces espaces le liquide qui se sera introduit lors du mélange des deux produits. De plus, ce dispositif nécessite un déplacement en translation important pour l'ouverture des moyens d'obturation, d'où un encombrement important après mélange.US-A-3 924 741 shows a device according to the first part of claim 1 in which the displacement of the closure means causes an increase in the internal volume of the assembly. However, this device has dead spaces; it will be extremely difficult to evacuate from these spaces the liquid which will have been introduced during the mixing of the two products. In addition, this device requires a significant translational movement for the opening of the closure means, resulting in a large size after mixing.

L'invention a pour but, surtout, de fournir un dispositif pour conserver séparés l'un de l'autre au moins deux produits, du genre défini précédemment, qui ne présente plus ou à un degré moindre les inconvénients rappelés ci-dessus. On souhaite en particulier que ce dispositif, lorsque les moyens d'obturation sont ouverts, permette d'assurer une bonne communication entre les récipients et un bon écoulement du mélange vers l'extérieur, sans que les moyens d'obturation puissent gêner cet écoulement d'une manière non contrôlée, qu'il ne comporte pas d'espaces morts et soit d'un faible encombrement. Il est souhaitable, en outre, que le dispositif reste d'une fabrication simple et économique, tout en assurant une bonne étanchéité entre les deux récipients, lors du stockage.The object of the invention is, above all, to provide a device for keeping separate at least two products, of the kind defined above, which no longer exhibits or to a lesser degree the drawbacks mentioned above. In particular, it is desired that this device, when the closure means are open, make it possible to ensure good communication between the containers and good flow of the mixture towards the outside, without the closure means being able to hinder this flow d 'in an uncontrolled manner, that it has no dead spaces and is of a small footprint. It is also desirable for the device to remain simple and economical to manufacture, while ensuring a good seal between the two containers, during storage.

    • et une cloison de fermeture munie d'un siège pour ledit plateau obturateur, liée au deuxième récipient,
    • l'ensemble étant tel, qu'en position de fermeture, le plateau obturateur est appliqué de manière étanche contre le siège tandis qu'un déplacement relatif approprié des deux récipients écarte le plateau du siège et assure l'ouverture des moyens d'obturation, le déplacement en translation entre les deux récipients, propre à provoquer l'ouverture des moyens d'obturation, assurant une augmentation du volume interne de l'ensemble des deux récipients,
caractérisé par le fait que le manchon s'étend du côté opposé à la jupe à partir de la couronne, que la cloison de fermeture constitue une sorte de couronne comportant, dans sa zone centrale, une ouverture formant siège pour le plateau obturateur, qu'une jupe d'étanchéité cylindrique s'étend vers le bas à partir de la face inférieure de la cloison pour coopérer avec le susdit manchon cylindrique, un passage annulaire étant compris entre le bord du plateau obturateur en position d'ouverture et la surface interne de la jupe.The present invention relates to a device for keeping separate at least two products and for carrying out their mixing at a desired time, in particular at the time of use, comprising:
  • a first container for one of the products,
  • at least a second container for at least one other product, the two containers being assembled in a sealed manner vis-à-vis the outside, while having a possibility of relative displacement, this second container being equipped with a capsule closed by a plug which can be broken or torn off, at the time of use, to release the mixture,

    • and a closing partition provided with a seat for said obturator plate, linked to the second container,
    • the assembly being such that, in the closed position, the shutter plate is applied in a sealed manner against the seat while an appropriate relative movement of the two containers separates the plate from the seat and ensures the opening of the shutter means, displacement in translation between the two containers, capable of causing the opening of the closure means, ensuring an increase in the internal volume of the assembly of the two containers,
characterized by the fact that the sleeve extends on the side opposite the skirt from the crown, that the closing partition constitutes a sort crown comprising, in its central area, an opening forming a seat for the shutter plate, a cylindrical sealing skirt extends downward from the underside of the partition to cooperate with the above cylindrical sleeve, a annular passage being between the edge of the shutter plate in the open position and the internal surface of the skirt.

De préférence, le plateau obturateur est situé au-delà du bord supérieur du manchon.Preferably, the shutter plate is located beyond the upper edge of the sleeve.

Avantageusement, le plateau obturateur est bloqué en rotation et en translation relativement au récipient auquel il est lié.Advantageously, the shutter plate is locked in rotation and in translation relative to the container to which it is linked.

De préférence, l'ensemble est tel que le déplacement relatif entre les deux récipients comprend au moins une composante de translation axiale, l'ouverture des moyens d'obturation étant assurée par le mouvement de translation axiale du plateau obturateur relativement au siège.Preferably, the assembly is such that the relative movement between the two containers comprises at least one component of axial translation, the opening of the shutter means being ensured by the movement of axial translation of the shutter plate relative to the seat.

Le déplacement relatif entre les deux récipients peut résulter de la combinaison d'un mouvement de rotation et d'un mouvement de translation par la coopération d'au moins une rampe hélicoïdale solidaire de l'un des deux récipients avec un ergot, engagé dans cette rampe, solidaire de l'autre récipient. Selon une autre possibilité, les deux récipients sont montés de manière à permettre un coulissement relatif entre eux.The relative displacement between the two containers can result from the combination of a rotational movement and a translational movement by the cooperation of at least one helical ramp integral with one of the two containers with a lug, engaged in this ramp, secured to the other container. According to another possibility, the two containers are mounted so as to allow relative sliding between them.

Généralement, le plateau obturateur est circulaire et coaxial aux récipients.Generally, the shutter plate is circular and coaxial with the containers.

Avantageusement, le plateau obturateur est porté par au moins deux pattes s'étendant sensiblement suivant la direction axiale des récipients, ces pattes étant solidaires, à leur extrémité éloignée du plateau obturateur, d'une couronne de base comportant une ouverture centrale.Advantageously, the obturator plate is carried by at least two tabs extending substantially in the axial direction of the containers, these tabs being integral, at their end remote from the obturator plate, with a base ring having a central opening.

Le plateau obturateur a de préférence un bord tronconique propre à coopérer avec un siège tronconique correspondant.The shutter plate preferably has a frustoconical edge capable of cooperating with a corresponding frustoconical seat.

La couronne portant le plateau obturateur peut faire partie d'une pièce indépendante, (ou obturateur), destinée à être fixée, notamment par claquage, sur le goulot de l'un des récipients. Cet obturateur comporte une jupe externe venant entourer le goulot du récipient, une lèvre d'étanchéité étant prévue pour coopérer avec l'entrée du goulot, des crans anti-rotation étant prévus entre la face interne de la jupe et la surface externe du goulot.The crown carrying the shutter plate can be part of an independent part, (or shutter), intended to be fixed, in particular by snap-fastening, on the neck of one of the containers. This shutter comprises an external skirt which surrounds the neck of the container, a sealing lip being provided to cooperate with the inlet of the neck, anti-rotation notches being provided between the internal face of the skirt and the external surface of the neck.

Un système de rampes hélicoïdales et d'ergots peut être prévu entre les deux récipients pour commander, à partir d'un mouvement de rotation, le déplacement relatif en translation ; de préférence, les ergots sont prévus solidaires du récipient équipé du plateau obturateur, tandis que les rampes hélicoïdales sont solidaires de l'autre récipient. Avantageusement, les rampes hélicoïdales sont fermées à leurs extrémités pour éviter toute désolidarisation due à un mouvement de rotation excessif entre les deux récipients. Un moyen d'arrêt en rotation est avantageusement prévu entre les deux récipients, ce moyen d'arrêt comprenant un cran longitudinal parallèle à l'axe des deux récipients et prévu sur la surface interne de l'un des récipients, ce cran étant propre à coopérer avec une rainure longitudinale correspondante prévue sur l'autre récipient ou une pièce solidaire de cet autre récipient, la coopération étant obtenue lorsque l'ensemble est en position de fermeture ou de stockage.A system of helical ramps and lugs can be provided between the two containers to control, from a rotational movement, the relative movement in translation; preferably, the pins are provided integral with the container equipped with the shutter plate, while the helical ramps are integral with the other container. Advantageously, the helical ramps are closed at their ends to avoid any separation due to an excessive rotational movement between the two containers. A rotational stop means is advantageously provided between the two containers, this stop means comprising a longitudinal notch parallel to the axis of the two containers and provided on the internal surface of one of the containers, this notch being suitable for cooperate with a corresponding longitudinal groove provided on the other container or a part integral with this other container, the cooperation being obtained when the assembly is in the closed or storage position.

La couronne solidaire des pattes portant le plateau obturateur peut être prévue directement sur l'un des récipients et former une seule pièce avec ce récipient.The crown secured to the tabs carrying the shutter plate can be provided directly on one of the containers and form a single piece with this container.

L'un au moins des récipients peut être constitué par une poche flexible.At least one of the containers can consist of a flexible pocket.

L'un des deux récipients est muni d'un moyen de distribution du mélange obtenu, ce moyen pouvant être constitué par un ajutage obturable par un bouchon.One of the two containers is provided with a means of distributing the mixture obtained, this means possibly consisting of a nozzle which can be closed off by a plug.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'exemples de réalisation décrits avec référence aux dessins ci-annexés, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with embodiments described with reference to the attached drawings, but which are in no way limiting.

La figure 13, enfin, est une coupe partielle à plus grande échelle, d'un détail d'une variante de réalisation du plateau obturateur et du siège des figures 1 à 4.FIG. 13, finally, is a partial section on a larger scale, of a detail of an alternative embodiment of the shutter plate and of the seat of FIGS. 1 to 4.

En se reportant aux dessins, notamment aux figures 1 et 2, on peut voir un dispositif D pour conserver séparés l'un de l'autre deux produits liquides A, B et pour effectuer leur mélange à un instant souhaité, notamment au moment de l'utilisation. Un tel dispositif convient en particulier pour les colorations d'oxydation, le liquide A correspondant au colorant tandis que le liquide B correspond à l'oxydant.Referring to the drawings, in particular to FIGS. 1 and 2, one can see a device D for keeping two liquid products A, B separate from each other and for mixing them at a desired time, in particular at the time of 'use. Such a device is particularly suitable for oxidation dyes, the liquid A corresponding to the dye while the liquid B corresponds to the oxidant.

Le dispositif D comporte un premier récipient 1 pour le produit A et un deuxième récipient 2 pour le produit B ; ce deuxième récipient 2 est monté sur le premier récipient 1 de manière étanche, vis-à-vis de l'extérieur. Des moyens d'obturation F propres à maintenir isolés l'un de l'autre les deux récipients, lors du stockage, sont en outre prévus.The device D comprises a first container 1 for product A and a second container 2 for product B; this second container 2 is mounted on the first container 1 in a sealed manner, vis-à-vis the outside. Sealing means F suitable for keeping the two containers isolated from one another, during storage, are also provided.

Le deuxième récipient 2 est équipé à son extrémité éloignée du premier récipient 1 d'une capsule de fermeture 3 munie d'un ajutage 4 fermé par un bouchon 5 qui peut être cassé ou arraché au moment de l'utilisation pour faire sortir le mélange.The second container 2 is equipped at its end remote from the first container 1 with a closure cap 3 provided with a nozzle 4 closed by a plug 5 which can be broken or torn off at the time of use to bring out the mixture.

Le récipient 1 comporte un corps 6, formant réservoir, réalisé en polychlorure de vinyle, ou en verre, ou en coextrusion de PEHD/EVOH/PEHD (polyéthylène haute densité/éthylène-vinyle-alcool/polyéthylène haute densité) pour contenir le liquide A. Le corps 6 est muni d'un goulot 7, généralement cylindrique, à section circulaire, dont l'extrémité supérieure est munie d'un rebord interne 8 formant collerette. La paroi extérieure du goulot comporte, vers la base du goulot, une gorge d'accrochage 9 délimitée, vers le haut, par une nervure 10 à section sensiblement en trapèze rectangle. La face de la nervure 10 tournée vers le fond du récipient 1 est située dans un plan orthogonal à l'axe du récipient.The container 1 comprises a body 6, forming a reservoir, made of polyvinyl chloride, or glass, or coextrusion of HDPE / EVOH / HDPE (high density polyethylene / ethylene-vinyl-alcohol / high density polyethylene) to contain the liquid A The body 6 is provided with a neck 7, generally cylindrical, with a circular section, the upper end of which is provided with an internal rim 8 forming a collar. The outer wall of the neck comprises, towards the base of the neck, a hooking groove 9 delimited, upwards, by a rib 10 of section substantially in a rectangular trapezoid. The face of the rib 10 facing the bottom of the container 1 is located in a plane orthogonal to the axis of the container.

La paroi du goulot 7 comporte, vers l'extérieur, au-dessus de la nervure 10, des dents 11 régulièrement réparties sur la périphérie, orientées parallèlement à l'axe du récipient.The wall of the neck 7 comprises, towards the outside, above the rib 10, teeth 11 regularly distributed over the periphery, oriented parallel to the axis of the container.

Dans l'exemple de réalisation des figures 1 à 4, les moyens d'obturation F sont constitués par une pièce 12, ou obturateur, indépendante du récipient 1. L'obturateur 12, réalisé en matière plastique, comporte une jupe périphérique 13, cylindrique, propre à venir entourer le goulot 7 du récipient. Cette jupe 13 comporte, sur sa surface interne, un jonc d'accrochage 14, faisant saillie radialement vers l'intérieur, propre à venir s'accrocher derrière la nervure 10 du goulot. La surface interne de la jupe 13 est en outre munie de dents anti-rotation 15 en saillie vers l'intérieur, parallèles à l'axe de la jupe 13 et propres à s'engager entre les dents 11 du goulot 7. Ainsi, lorsque l'obturateur 12 est claqué sur le goulot 7, il se trouve bloqué en rotation et en translation relativement au goulot 7 et au récipient 1. Le blocage en translation résulte de l'action du jonc 14 coopérant avec la nervure 10 et de l'appui du bord inférieur de la jupe 13 contre la paroi du récipient 1 élargie à la base du goulot 7.In the embodiment of Figures 1 to 4, the shutter means F are constituted by a part 12, or shutter, independent of the container 1. The shutter 12, made of plastic, has a peripheral skirt 13, cylindrical , suitable for surrounding the neck 7 of the container. This skirt 13 has, on its internal surface, a snap ring 14, projecting radially inwards, suitable for being hooked behind the rib 10 of the neck. The internal surface of the skirt 13 is also provided with anti-rotation teeth 15 projecting inwards, parallel to the axis of the skirt 13 and suitable for engaging between the teeth 11 of the neck 7. Thus, when the shutter 12 is slammed on the neck 7, it is blocked in rotation and in translation relative to the neck 7 and to the container 1. The blocking in translation results from the action of the rod 14 cooperating with the rib 10 and the support of the lower edge of the skirt 13 against the wall of the container 1 widened at the base of the neck 7.

La jupe 13, sur sa surface cylindrique extérieure, comporte au moins deux ergots 16 de guidage destinés à coopérer avec des rampes hélicoïdales 17 correspondantes prévues à la partie inférieure de la surface interne du deuxième récipient 2. Les ergots 16 sont inclinés au même pas que les rampes 17. Ces rampes sont fermées à leurs extrémités (rampes non débouchantes).The skirt 13, on its outer cylindrical surface, comprises at least two guide pins 16 intended to cooperate with corresponding helical ramps 17 provided at the lower part of the internal surface of the second container 2. The pins 16 are inclined at not even the ramps 17. These ramps are closed at their ends (non-opening ramps).

La jupe 13 comporte, au-dessus des ergots 16, une couronne 18 dont le plan moyen est orthogonal à l'axe de la jupe, cette couronne 18 s'étendant vers l'intérieur dans le sens radial. Le bord interne de cette couronne est munie d'une lèvre d'étanchéité 19 formant une sorte de manchon qui s'engage de manière étanche à l'intérieur du rebord 8 du goulot, et qui délimite une ouverture 18a.The skirt 13 comprises, above the lugs 16, a ring 18 whose mean plane is orthogonal to the axis of the skirt, this ring 18 extending inwards in the radial direction. The internal edge of this crown is provided with a sealing lip 19 forming a sort of sleeve which engages in a sealed manner inside the rim 8 of the neck, and which delimits an opening 18 a .

Un manchon cylindrique 20, d'épaisseur plus faible que celle de la jupe 13, et de diamètre extérieur plus faible également, s'étend du côté opposé à la jupe 13 à partir de la couronne 18. Le manchon 20 comporte, sur sa surface interne, vers son extrémité éloignée de la couronne 18, un jonc d'étanchéité 21 faisant saillie radialement vers l'intérieur.A cylindrical sleeve 20, of thickness less than that of the skirt 13, and also of smaller external diameter, extends on the side opposite to the skirt 13 from the crown 18. The sleeve 20 has, on its surface internal, towards its end remote from the crown 18, a sealing ring 21 projecting radially inwards.

Un plateau obturateur 22, dont le plan moyen est orthogonal à l'axe de la jupe 13, est porté, à distance h de la couronne 18, par des pattes 23, de préférence au nombre de trois, régulièrement espacées. Le plateau 22 est situé au-delà du bord supérieur du manchon 21 et son diamètre est inférieur à celui de l'ouverture de la couronne 18. Les pattes 23 sont légèrement inclinées relativement à l'axe de la jupe 13 et sont solidaires, à leur extrémité éloignée du plateau 22, de la couronne 18 dans la zone du bord interne. Le bord 24 du plateau 22 est avantageusement tronconique. Le plateau 22 a la forme d'un disque circulaire, coaxial au récipient 1.A shutter plate 22, the mean plane of which is orthogonal to the axis of the skirt 13, is carried, at distance h from the crown 18, by lugs 23, preferably three in number, regularly spaced. The plate 22 is located beyond the upper edge of the sleeve 21 and its diameter is less than that of the opening of the crown 18. The legs 23 are slightly inclined relative to the axis of the skirt 13 and are integral with their end remote from the plate 22, from the crown 18 in the area of the internal edge. The edge 24 of the plate 22 is advantageously frustoconical. The plate 22 has the shape of a circular disc, coaxial with the container 1.

Le plateau obturateur 22 forme une seule pièce avec la couronne 18, la jupe 13 et le manchon 20. La distance h du plateau 22 à la couronne 18 est suffisante pour qu'un passage annulaire de section suffisante existe entre le plateau 22 et ladite couronne 18.The shutter plate 22 forms a single piece with the crown 18, the skirt 13 and the sleeve 20. The distance h from the plate 22 to the crown 18 is sufficient for an annular passage of sufficient section to exist between the plate 22 and said crown 18.

La jupe 13 comporte, sur sa surface cylindrique extérieure, au moins une rainure longitudinale 25, parallèle à l'axe de la jupe, propre à coopérer avec un cran 26 (voir figure 1) en saillie vers l'intérieur prévu sur la surface interne du deuxième récipient 2. Le cran 26 a une orientation longitudinale, parallèle à l'axe du récipient 2, d'une manière semblable à la rainure 25. Les positions angulaires de la rainure 25 et du cran 26 sont choisies de telle sorte que le cran 26 entre dans la rainure 25 lorsque le plateau obturateur 22 arrive dans sa position de fermeture. Ainsi, lors du stockage ou lors des manipulations du dispositif D en position fermée, la coopération du cran 26 et de la rainure 25 empêche que des vibrations, notamment lors des transports, provoquent un dévissage relatif des deux récipients 1 et 2 et donc une ouverture intempestive du plateau obturateur 22 avec mise en communication non souhaitée des deux récipients 1 et 2.The skirt 13 has, on its external cylindrical surface, at least one longitudinal groove 25, parallel to the axis of the skirt, suitable for cooperating with a notch 26 (see FIG. 1) projecting inwards provided on the internal surface of the second container 2. The notch 26 has a longitudinal orientation, parallel to the axis of the container 2, in a manner similar to the groove 25. The angular positions of the groove 25 and the notch 26 are chosen so that the notch 26 enters the groove 25 when the shutter plate 22 reaches its position of closing. Thus, during storage or when handling the device D in the closed position, the cooperation of the notch 26 and the groove 25 prevents vibrations, in particular during transport, causing a relative unscrewing of the two containers 1 and 2 and therefore an opening inadvertent shutter plate 22 with unwanted communication between the two containers 1 and 2.

Le deuxième récipient 2, a une forme cylindrique de révolution ; sa paroi extérieure 27 est de préférence souple de manière à pouvoir être déformée, comme illustré sur la figure 4, afin d'améliorer l'évacuation du mélange. Dans le cas d'une teinture d'oxydation, où ce récipient 2 contient l'oxydant, le récipient 2 est avantageusement réalisé en polypropylène ou en polyéthylène.The second container 2 has a cylindrical shape of revolution; its outer wall 27 is preferably flexible so as to be able to be deformed, as illustrated in FIG. 4, in order to improve the evacuation of the mixture. In the case of an oxidation dye, where this container 2 contains the oxidant, the container 2 is advantageously made of polypropylene or polyethylene.

Le récipient 2 comprend une cloison interne 28 légèrement tronconique, tournant sa concavité vers le récipient 1, et constituant une sorte de couronne comportant, dans sa zone centrale, une ouverture formant siège 29 pour le plateau obturateur 22. Le bord 30 du siège 29 est tronconique de manière à épouser le bord 24 du plateau 22 en position de fermeture.The container 2 comprises an internal partition 28 slightly frustoconical, turning its concavity towards the container 1, and constituting a sort of crown comprising, in its central zone, an opening forming a seat 29 for the shutter plate 22. The edge 30 of the seat 29 is frustoconical so as to match the edge 24 of the plate 22 in the closed position.

Une jupe d'étanchéité 31 cylindrique, coaxiale à la paroi 27, s'étend vers le bas à partir de la face inférieure de la cloison 28. Le diamètre de la surface extérieure de cette jupe 31 est tel qu'elle entre avec un certain serrage dans le jonc d'étanchéité 21, comme illustré sur la figure 2, pour l'établissement d'une étanchéité coulissante, qui se maintient pendant tout le déplacement possible entre les deux récipients 1 et 2.A cylindrical sealing skirt 31, coaxial with the wall 27, extends downward from the underside of the partition 28. The diameter of the external surface of this skirt 31 is such that it enters with a certain tightening in the sealing ring 21, as illustrated in FIG. 2, to establish a sliding seal, which is maintained throughout the possible movement between the two containers 1 and 2.

La zone de la surface intérieure de la paroi 27, située au-dessous de la cloison 28, comporte les rampes hélicoïdales 17 non débouchantes, déjà évoquées, dont le nombre correspond au nombre d'ergots 16. La pente de l'hélice et la longueur de chaque rampe sont choisies en fonction de l'amplitude du déplacement axial souhaité entre les deux récipients 1 et 2, et donc entre le plateau 22 et le siège 29 pour l'ouverture. De petites rampes d'accès 32 en nombre égal à celui des ergots 16, sont prévues pour faciliter l'introduction de ces ergots 16 dans les rampes 17 et ainsi claquer la base 33 du récipient 2 sur la jupe 13 et pour permettre le montage de l'obturateur 12 et du récipient 2 positionnés en position fermée.The area of the inner surface of the wall 27, located below the partition 28, includes the helical ramps 17 not emerging, already mentioned, the number of which corresponds to the number of lugs 16. The slope of the propeller and the length of each ramp are chosen as a function of the amplitude of the axial displacement desired between the two containers 1 and 2, and therefore between the plate 22 and the seat 29 for opening. Small access ramps 32 in number equal to that of the lugs 16, are provided to facilitate the introduction of these lugs 16 into the ramps 17 and thus snap the base 33 of the container 2 onto the skirt 13 and to allow the mounting of the shutter 12 and the container 2 positioned in the closed position.

L'extrémité supérieure du récipient 2 est munie de la capsule de fermeture 3 comprenant une jupe cylindrique 34 et un chapeau tronconique 35 à la pointe duquel se trouve l'ajutage 4. Sur la surface interne de la jupe 34 est prévu un filetage propre à coopérer avec un filetage complémentaire 36 prévu sur la surface extérieure de la paroi 27 du récipient 2. Il est ainsi possible, pour un opérateur, de dévisser la capsule 3 et de prélever un peu de produit oxydant B pour réaliser une touche d'essai avec un échantillon de colorant séparé.The upper end of the container 2 is provided with the closure cap 3 comprising a cylindrical skirt 34 and a frustoconical cap 35 at the tip of which is the nozzle 4. On the internal surface of the skirt 34 is provided a thread suitable for cooperate with a complementary thread 36 provided on the external surface of the wall 27 of the container 2. It is thus possible, for an operator, to unscrew the capsule 3 and take a little oxidizing product B to carry out a test touch with a separate dye sample.

Une jupe d'étanchéité 37, coaxiale au récipient 2, s'étend vers le bas à partir de la face interne du chapeau tronconique 35 de manière à s'engager, avec un léger serrage assurant une étanchéité, contre un jonc d'étanchéité 38 prévu en bordure interne de l'ouverture supérieure de la paroi 27.A sealing skirt 37, coaxial with the container 2, extends downwards from the internal face of the frustoconical cap 35 so as to engage, with a slight tightening ensuring a sealing, against a sealing ring 38 provided on the inner edge of the upper opening of the wall 27.

Le montage du dispositif D peut être réalisé à l'aide de trois sous-ensembles constitués respectivement par le récipient 1, l'obturateur 12 et le récipient 2 claqués en position fermée, et la capsule 3.The mounting of the device D can be carried out using three sub-assemblies constituted respectively by the container 1, the shutter 12 and the container 2 slammed in the closed position, and the capsule 3.

Le récipient 1 est d'abord rempli en produit A, puis le sous-ensemble formé par l'obturateur 12 et le récipient 2 est claqué sur le récipient 1, le jonc d'accrochage 14 de la jupe 13 venant alors s'accrocher derrière la nervure 10.The container 1 is first filled with product A, then the sub-assembly formed by the shutter 12 and the container 2 is slammed on the container 1, the snap ring 14 of the skirt 13 then coming to hang behind rib 10.

Le remplissage du récipient 2 en liquide B est ensuite effectué, puis la capsule 3 est vissée sur l'extrémité supérieure de la paroi 27. On obtient ainsi le dispositif D en position de stockage, contenant séparés l'un de l'autre les produits A et B.The filling of the container 2 with liquid B is then carried out, then the capsule 3 is screwed onto the upper end of the wall 27. The device D is thus obtained in the storage position, containing the products separated from one another. A and B.

Au moment de l'utilisation, lorsque l'opérateur souhaite réaliser le mélange des deux produits A et B, il lui suffit de saisir le récipient 1 d'une main et la paroi 27 du récipient 2 de l'autre main. En imprimant un mouvement de rotation relatif aux deux récipients 1 et 2, l'opérateur provoque une translation.axiale des récipients 1 et 2 qui s'éloignent l'un de l'autre, de sorte que le plateau obturateur 22 s'écarte du siège 29 et permet l'écoulement d'un produit dans l'autre pour le mélange.At the time of use, when the operator wishes to mix the two products A and B, he need only grasp the container 1 with one hand and the wall 27 of the container 2 with the other hand. By imparting a rotational movement relative to the two containers 1 and 2, the operator causes an axial translation of the containers 1 and 2 which move away from each other, so that the shutter plate 22 moves away from the seat 29 and allows the flow of one product in the other for mixing.

L'obturateur 12 et le récipient 2 ne peuvent être séparés l'un de l'autre car les ergots 16 sont prisonniers dans les rampes 17 fermées à chacune de leurs extrémités.The shutter 12 and the container 2 cannot be separated from each other because the pins 16 are trapped in the ramps 17 closed at each of their ends.

Après avoir effectué, par exemple, une rotation d'un demi-tour entre les récipients 1 et 2, l'opérateur retourne le dispositif D afin que le produit contenu dans le récipient 1 s'écoule dans le récipient 2 dont le volume a été déterminé en conséquence. L'opérateur agite ensuite le dispositif D pour réaliser un mélange homogène. Après avoir cassé le bouchon 5 ou embout, l'opérateur peut distribuer le mélange en exerçant une pression sur le corps souple du récipient 2, comme illustré sur la figure 4.After having carried out, for example, a rotation of half a turn between the containers 1 and 2, the operator turns over the device D so that the product contained in the container 1 flows into the container 2 whose volume has been determined accordingly. The operator then shakes the device D to produce a homogeneous mixture. After having broken the plug 5 or end piece, the operator can dispense the mixture by applying pressure to the flexible body of the container 2, as illustrated in FIG. 4.

Il est à noter que les dimensions des différents éléments sont choisies, de préférence, de manière à respecter sensiblement une égalité de la section de passage pour le mélange aux différents niveaux. En particulier, les dimensions sont choisies de manière que la section S1 (voir figure 4) de l'ouverture 18a délimitée par la lèvre d'étanchéité 19 soit sensiblement égale à la section S2 du passage annulaire compris entre le bord 24, du plateau obturateur 22 en position d'ouverture, et la surface interne de la jupe 31, et soit sensiblement égale à la section S3 de passage du siège 29.It should be noted that the dimensions of the various elements are preferably chosen so as to substantially respect an equality of the passage section for mixing at the different levels. In particular, dimensions are selected so that the section S1 (see FIG 4) of the aperture 18 enclosed by the sealing lip 19 is substantially equal to the S2 section of the annular passage between the edge 24 of the plate shutter 22 in the open position, and the internal surface of the skirt 31, and is substantially equal to the section S3 of passage of the seat 29.

En se reportant à la figure 5, on peut voir une variante de réalisation reprenant la plupart des éléments déjà décrits à propos des figures précédentes et désignés par les mêmes références numériques, sans que leur description soit reprise.Referring to Figure 5, we can see an alternative embodiment incorporating most of the elements already described with reference to the previous figures and designated by the same reference numerals, without their description being repeated.

Pour améliorer la souplesse du récipient supérieur 102, le corps 39 est réalisé par injection soufflage. La partie inférieure 40 du récipient 102 constitue un séparateur proprement dit et comporte la cloison 28. Cette partie 40 est fixée de manière étanche à la base du corps 39. Le bord inférieur 41 du corps 39 est engagé dans une gorge 42. La zone inférieure du corps 39, de diamètre réduit, comporte sur sa surface extérieure un jonc d'accrochage 43 venant se claquer derrière un rebord d'accrochage 44 prévu sur la surface intérieure de la partie 40.To improve the flexibility of the upper container 102, the body 39 is produced by injection blowing. The lower part 40 of the container 102 constitutes a separator proper and comprises the partition 28. This part 40 is tightly fixed to the base of the body 39. The lower edge 41 of the body 39 is engaged in a groove 42. The lower zone of the body 39, of reduced diameter, comprises on its outer surface a snap ring 43 snapping behind a snap rim 44 provided on the inner surface of the part 40.

Le montage et le fonctionnement du dispositif illustré sur la figure 5 sont semblables à ceux décrits précédemment.The assembly and operation of the device illustrated in Figure 5 are similar to those described above.

Il est à noter que le récipient 1 pourrait être réalisé également avec des parois souples, notamment dans le cas où les produits à mélanger sont destinés à la réalisation d'une permanente.It should be noted that the container 1 could also be produced with flexible walls, in particular in the case where the products to be mixed are intended for the production of a perm.

La figure 6 illustre une autre variante de réalisation correspondant à une version mélangeur-tube. Le récipient 201 est agencé sous la forme d'un tube T, et l'obturateur 212 forme une seule et même pièce avec ce tube T dont il constitue la tête. Dans ce cas, le dispositif D est composé de trois pièces seulement à savoir le récipient inférieur 201 avec l'obturateur, le récipient supérieur 2 et la capsule 3.FIG. 6 illustrates another alternative embodiment corresponding to a mixer-tube version. The container 201 is arranged in the form of a tube T, and the shutter 212 forms a single piece with this tube T of which it constitutes the head. In this case, the device D is composed of only three parts, namely the lower container 201 with the shutter, the upper container 2 and the capsule 3.

Les figures 7 à 10 illustrent, partiellement, une variante de réalisation qui ne diffère de celle des figures 1 à 4 qu'au niveau des rampes 317 du récipient 302 et des moyens complémentaires prévus sur la surface extérieure de la jupe 313.FIGS. 7 to 10 partially illustrate an alternative embodiment which differs from that of FIGS. 1 to 4 only at the level of the ramps 317 of the container 302 and additional means provided on the external surface of the skirt 313.

Les rampes 317 sont constituées par un pas de vis traditionnel au lieu d'être constituées par des rampes non débouchantes, comme dans le cas des figures 1 à 4. La jupe 313 est munie, sur sa surface extérieure, d'un filetage 316, conjugué des rampes 317.The ramps 317 are formed by a traditional screw pitch instead of being formed by non-opening ramps, as in the case of FIGS. 1 to 4. The skirt 313 is provided, on its outer surface, with a thread 316, conjugate ramps 317.

Pour éviter que l'obturateur 312 puisse se détacher du récipient 302 en fin de dévissage, des harpons 45, faisant saillie radialement vers l'extérieur, sont prévus à la base de la jupe 302, au bout des pattes 48.To prevent the obturator 312 from detaching from the container 302 at the end of unscrewing, harpoons 45, projecting radially outward, are provided at the base of the skirt 302, at the end of the legs 48.

Les deux harpons 45 viennent s'insérer (après vissage de 302 sur 312) sous une bande arrachable 47, après avoir traversé deux fenêtres 46 en arc de cercle (voir figures 9 et 10). Les longueurs de ces fenêtres 46 sont variables suivant la rotation que l'on souhaite obtenir pour 302.The two harpoons 45 are inserted (after screwing 302 on 312) under a tear-off strip 47, after having crossed two windows 46 in an arc of a circle (see FIGS. 9 and 10). The lengths of these windows 46 are variable depending on the rotation that one wishes to obtain for 302.

La hauteur de la bande arrachable 47 est suffisante pour permettre le déplacement relatif en translation verticale entre les récipients 1 et 302, nécessaire pour réaliser une communication convenable entre ces récipients.The height of the tear-off strip 47 is sufficient to allow the relative displacement in vertical translation between the containers 1 and 302, necessary to achieve suitable communication between these containers.

Dans la position de fermeture du plateau obturateur 22, les harpons 45 se trouvent sous la bande arrachable 47. Pour écarter l'obturateur 22 de son siège 29, l'utilisateur doit retirer la bande arrachable 47 reliée à la jupe 313 par une zone fragilisée, ce qui autorise la montée des pattes 48 dans les fenêtres 46.In the closed position of the shutter plate 22, the harpoons 45 are located under the tear-off strip 47. To move the shutter 22 away from its seat 29, the user must remove the tear-off strip 47 connected to the skirt 313 by a weakened area , which authorizes the rise of the legs 48 in the windows 46.

En fin de dévissage, les harpons 45 viennent en appui contre le bord inférieur des fenêtres 46, ce qui marque l'arrêt du dévissage possible.At the end of unscrewing, the harpoons 45 bear against the lower edge of the windows 46, which marks the end of the possible unscrewing.

En se reportant aux figures 11 et 12, on peut voir, représentée partiellement, une variante de réalisation du type "pousser-tirer" dans laquelle le déplacement relatif entre le récipient 1 et le récipient 402 peut être obtenu par un unique mouvement de translation axiale.Referring to Figures 11 and 12, we can see, partially shown, an alternative embodiment of the type "push-pull" in which the relative movement between the container 1 and the container 402 can be obtained by a single axial translation movement.

L'obturateur 412, qui est toujours fixé par claquage sur le goulot 7 du récipient 1, comporte une couronne 418 ayant une ouverture centrale 418a dont le diamètre est inférieur à celui de la lèvre 419. Un manchon 420 est solidaire du bord interne de la couronne 418 et s'étend, suivant la direction axiale, du côté opposé à la jupe 413. Le bord supérieur de ce manchon 420 est solidaire de pattes 423 portant le plateau 22.The shutter 412, which is always fixed by snap-fastening on the neck 7 of the container 1, comprises a crown 418 having a central opening 418 a whose diameter is less than that of the lip 419. A sleeve 420 is integral with the internal edge of the ring 418 and extends, in the axial direction, on the side opposite to the skirt 413. The upper edge of this sleeve 420 is integral with lugs 423 carrying the plate 22.

Le manchon 420 est propre à se déplacer à l'intérieur de la jupe 431 solidaire de la cloison 428 du deuxième récipient 402. Un bourrelet périphérique 49 est prévu sur la surface extérieure du manchon 420 de manière à frotter contre la surface interne de la jupe 431.The sleeve 420 is able to move inside the skirt 431 integral with the partition 428 of the second container 402. A peripheral bead 49 is provided on the external surface of the sleeve 420 so as to rub against the internal surface of the skirt 431.

Un bourrelet interne 50 est prévu, sur la surface interne de la jupe 431, au voisinage de son extrémité inférieure. Ce bourrelet 50 frotte de manière étanche contre la surface extérieure du manchon 420.An internal bead 50 is provided on the internal surface of the skirt 431, in the vicinity of its lower end. This bead 50 rubs tightly against the outer surface of the sleeve 420.

Les bourrelets 49 et 50 sont propres à venir en appui l'un contre l'autre pour marquer la fin du mouvement de translation autorisé entre le récipient 402 et le récipient 1, comme illustré sur la figure 12.The beads 49 and 50 are capable of coming to bear against one another to mark the end of the authorized translational movement between the container 402 and the container 1, as illustrated in FIG. 12.

Dans l'exemple de réalisation des figures 11 et 12, le récipient 402 et l'obturateur 412 sont libres non seulement en translation mais également en rotation.In the embodiment of Figures 11 and 12, the container 402 and the shutter 412 are free not only in translation but also in rotation.

Il est possible de prévoir un blocage relatif en rotation des deux éléments à l'aide de rampes, non débouchantes, parallèles à l'axe des récipients ; ces rampes seraient prévues, par exemple, sur le récipient 402 pour coopérer avec des ergots correspondants prévus sur le récipient 1 ou l'obturateur 412. Dans ce dernier cas, seul un mouvement de translation axiale serait autorisé, la coopération des rampes et des ergots interdisant le mouvement de rotation.It is possible to provide a relative blocking in rotation of the two elements using ramps, not emerging, parallel to the axis of the containers; these ramps would be provided, for example, on the container 402 to cooperate with corresponding lugs provided on the container 1 or the shutter 412. In the latter case, only an axial translation movement would be authorized, the cooperation of the ramps and lugs prohibiting rotational movement.

La figure 13 illustre une variante de réalisation du plateau obturateur 522 et de l'ouverture 529 des figures 1 à 4.FIG. 13 illustrates an alternative embodiment of the shutter plate 522 and of the opening 529 of FIGS. 1 to 4.

Le plateau obturateur 522 est muni, sur sa face supérieure, d'une nervure périphérique 51 en saillie vers le haut, en forme de couronne à section triangulaire. La nervure 51 s'étend suivant tout le tour de l'obturateur 522, légèrement en retrait du bord.The shutter plate 522 is provided, on its upper face, with a peripheral rib 51 projecting upwards, in the form of a crown with a triangular section. The rib 51 extends along the entire turn of the shutter 522, slightly set back from the edge.

La cloison interne 528 est munie, sur sa face inférieure, d'une gorge 52 de section complémentaire de la nervure 51. Cette gorge 52 est délimitée par deux jupes 53, 54, en saillie vers le bas. Les jupes 53, 54 sont constituées par des couronnes à section triangulaire, situées légèrement à l'extérieur, dans le sens radial, du bord de l'ouverture 529. Par un mouvement de translation axiale, la nervure 51 peut être appliquée de manière étanche dans la gorge 52.The internal partition 528 is provided, on its lower face, with a groove 52 of complementary section of the rib 51. This groove 52 is delimited by two skirts 53, 54, projecting downwards. The skirts 53, 54 are constituted by crowns of triangular section, located slightly outside, in the radial direction, from the edge of the opening 529. By an axial translational movement, the rib 51 can be applied in a sealed manner in the throat 52.

Sur la figure 13, la nervure 51 a été représentée légèrement écartée de ladite gorge 52.In FIG. 13, the rib 51 has been shown slightly apart from said groove 52.

Quelle que soit la variante de réalisation, l'invention permet de réaliser le mélange des deux produits dans de bonnes conditions, sans que l'obturateur, fixé à l'un des récipients ou à une pièce solidaire de l'un des récipients, vienne gêner, de manière non contrôlée, la réalisation du mélange.Whatever the variant embodiment, the invention makes it possible to mix the two products in good conditions, without the shutter, fixed to one of the containers or to a part integral with one of the containers, coming hinder, in an uncontrolled manner, the production of the mixture.
