Abstract

The assembly has two containers containing products, and a movable actuator component (50) to actuate distribution of the products in a mixed or separate state. An intermediate body separates from the component and comprises two skirts. The component has two rigid tabs which contact the intermediate body in two support zones (170a, 170b) spaced apart from each other in order to cause the intermediate body to tilt.

Description

L'invention concerne la distribution de deux produits à mélanger extemporanément, et plus particulièrement mais non exclusivement, deux produits de coloration pour les cheveux.The invention relates to the distribution of two products to be mixed extemporaneously, and more particularly but not exclusively, two hair coloring products.

On connaît de nombreux dispositifs permettant le mélange extemporané de deux produits stockés séparément.Numerous devices are known for the extemporaneous mixing of two products stored separately.

Ainsi, on connaît par la demande de brevet français FR-A-2 732 245 un ensemble de distribution comportant un corps et un bouton-poussoir mobile par rapport à ce corps pour provoquer la distribution simultanée et séparée de deux produits à partir de deux récipients dans lesquels ces produits sont stockés séparément, chaque récipient étant pourvu d'une valve comportant une tige creuse d'actionnement dont l'enfoncement provoque la distribution du produit.Thus, French Patent Application FR-A-2 732 245 discloses a dispensing assembly comprising a body and a push-button movable relative to this body to cause the simultaneous and separate dispensing of two products from two containers. wherein these products are stored separately, each container being provided with a valve having a hollow actuating rod whose depression causes the distribution of the product.

Une difficulté avec certains ensembles de distribution connus provient du fait que les tiges d'actionnement peuvent avoir des extrémités supérieures qui ne sont pas situées exactement au même niveau compte tenu des tolérances de fabrication, ce qui entraîne un risque de distribution non simultanée des produits.A difficulty with some known dispensing assemblies arises from the fact that the actuating rods may have upper ends that are not located exactly at the same level given the manufacturing tolerances, which entails a risk of non-simultaneous distribution of the products.

D'autres ensembles de distribution ont été proposés, n'offrant toutefois pas entière satisfaction.Other distribution packages have been proposed, but not entirely satisfactory.

A titre d'exemple, on peut citer le brevet US 3,236,457, les demandes de brevet européen EP-A-0 313 414, EP-A-0 427 609 ou EP-A 0 243 667, le brevet britannique GB 1,163,978 ou encore les demandes de brevet français FR-A-2 598 392 et FR-A-1 413 164.By way of example, mention may be made of US Pat. No. 3,236,457, European Patent Applications EP-A-0 313 414, EP-A-0 427 609 or EP-A 0 243 667, British Patent GB 1,163,978, or the US Pat. French patent applications FR-A-2 598 392 and FR-A-1 413 164.

La demande de brevet FR 2815616 décrit également un ensemble de distribution de ce type dans lequel les tiges d'actionnement sont enfoncées en réponse à la manoeuvre d'un unique élément d'actionnement. Toutefois, un élément d'actionnement comportant un bras de levier est nécessaire pour enfoncer les deux tiges d'actionnement sans trop de difficulté.The patent application FR 2815616 also describes a distribution assembly of this type in which the actuating rods are driven in response to the operation of a single actuating element. However, a an actuating element having a lever arm is required to drive the two actuating rods without much difficulty.

Il existe un besoin pour disposer d'un ensemble de distribution qui puisse distribuer la même quantité de produit provenant de chaque récipient.There is a need for a dispensing assembly that can dispense the same amount of product from each container.

Il existe également un besoin pour disposer d'un ensemble de distribution qui puisse facilement s'actionner.There is also a need to have a distribution set that can easily be operated.

Il existe aussi un besoin pour disposer d'un ensemble qui limite la distribution accidentelle des produits.There is also a need to have a set that limits the accidental distribution of products.

Il existe également un besoin pour disposer d'un ensemble qui permette de minimiser l'oxydation des produits à distribuer.There is also a need to have an assembly that minimizes the oxidation of the products to be dispensed.

    • an intermediate member, separate from the actuating element, comprising two skirts adapted to engage respectively on the two actuating rods of the containers and at least one inner channel for the flow of products to the dispensing tip;
    the actuating element and the intermediate member being arranged to cooperate during the operation of the actuating element so as to allow the passage of the products from the containers to the dispensing nozzle, via the inner channel. The actuating rods can be actuated by tilting and the actuating element can be configured to tilt the intermediate member so as to tilt the actuating rods.

Les tiges d'actionnement pouvant s'actionner par basculement, elles nécessitent une faible force d'appui pour être actionnées ce qui permet un confort à l'utilisation. Le produit peut en effet sortir des tiges d'actionnement au moindre basculement de celles-ciThe actuating rods can be actuated by tilting, they require a low support force to be actuated which allows comfort in use. The product can indeed come out of the actuating rods at the slightest tilting thereof

L'élément d'actionnement peut comporter au moins deux pattes, de préférence rigides, aptes à venir en appui sur l'organe intermédiaire en au moins deux zones d'appui espacées l'une de l'autre pour faire basculer l'organe intermédiaire. En utilisant deux zones d'appui distinctes, on peut plus facilement garantir l'actionnement simultané des deux tiges d'actionnement des deux récipients. On peut ainsi distribuer la même quantité de produit provenant de chaque récipient.The actuating element may comprise at least two tabs, preferably rigid, able to bear on the intermediate member in at least two support zones spaced from one another to tilt the intermediate member . By using two separate support zones, it is more easily possible to ensure simultaneous actuation of the two actuating rods of the two receptacles. It is thus possible to dispense the same amount of product from each container.

La distance entre l'une des zones d'appui et l'une des jupes peut être sensiblement identique à la distance entre l'autre zone d'appui et l'autre jupe. On garantit encore l'actionnement simultané des deux tiges d'actionnement. De préférence, on utilise des zones d'appui qui se trouvent dans l'axe des tiges d'actionnement.The distance between one of the support zones and one of the skirts may be substantially identical to the distance between the other support zone and the other skirt. It is still guaranteed the simultaneous actuation of the two actuating rods. Preferably, support zones are used which are in the axis of the actuating rods.

Chaque patte peut comporter un bord incliné destiné à venir en appui sur l'organe intermédiaire.Each leg may comprise an inclined edge intended to bear on the intermediate member.

L'embout de distribution et l'élément intermédiaire peuvent être agencés de manière telle que le basculement de l'élément intermédiaire entraîne le basculement de l'embout de distribution lors de la manoeuvre de l'élément d'actionnement.The dispensing nozzle and the intermediate element may be arranged in such a way that the tilting of the intermediate element causes the dispensing nozzle to tilt during the operation of the actuating element.

L'organe intermédiaire peut comporter un conduit de sortie par lequel sortent les produits à l'état séparé ou mélangé, l'embout de distribution pouvant comporter une embouchure apte à recevoir ce conduit de sortie.The intermediate member may comprise an outlet duct through which the products come out in the separated or mixed state, the dispensing nozzle may comprise a mouthpiece adapted to receive this outlet duct.

L'organe intermédiaire peut être agencé pour canaliser séparément les produits jusqu'à l'embout de distribution ou alternativement pour permettre le mélange des produits avant que ces derniers ne gagnent l'embout de distribution.The intermediate member may be arranged to channel the products separately to the dispensing nozzle or alternatively to allow mixing products before they win the distribution tip.

L'embout de distribution peut être agencé pour canaliser séparément les produits jusqu'à son extrémité libre qui délimite deux orifices de distribution.The dispensing nozzle may be arranged to channel products separately to its free end which defines two dispensing orifices.

Le dispositif de distribution peut comporter un collier d'assemblage apte à s'encliqueter sur des collerettes formées sur les récipients.The dispensing device may comprise an assembly collar adapted to snap on collars formed on the containers.

L'embout de distribution peut être relié par une bande souple à une jupe de montage qui peut être apte à s'encliqueter sur le collier d'assemblage.The dispensing tip can be connected by a flexible band to a mounting skirt which can be adapted to snap onto the assembly collar.

Le dispositif de distribution peut comporter un capot destiné à protéger l'embout de distribution.The dispensing device may comprise a cover intended to protect the dispensing nozzle.

L'extrémité libre de l'embout peut être apte à s'éloigner du capot lors de la manoeuvre de l'élément d'actionnement.The free end of the nozzle may be adapted to move away from the hood during the operation of the actuating element.

Le capot peut comporter un volet apte à fermer l'extrémité libre de l'embout de distribution. Le volet peut en outre être configuré pour, lorsqu'il est fermé, empêcher un déplacement de l'élément d'actionnement suffisant pour provoquer la distribution des produits. A cet effet, le volet peut comporter un élément en saillie apte à se loger dans le conduit de l'embout de distribution de manière à limiter, voire empêcher, un mouvement de l'embout par rapport au capot.The cover may comprise a flap adapted to close the free end of the dispensing nozzle. The shutter may further be configured to, when closed, prevent movement of the actuating element sufficient to cause dispensing of the products. For this purpose, the flap may comprise a projecting element adapted to be housed in the duct of the dispensing nozzle so as to limit, or prevent, movement of the nozzle relative to the hood.

Le collier d'assemblage peut comporter des jupes tubulaires définissant des logements destinés à recevoir les récipients.The assembly collar may comprise tubular skirts defining housing for receiving the containers.

Les récipients peuvent contenir des produits à mélanger extemporanément.The containers may contain products to be mixed extemporaneously.

Les récipients peuvent contenir des produits cosmétiques, notamment des produits de coloration.The containers may contain cosmetic products, especially coloring products.

On a représenté sur la figure 1 un ensemble de distribution 10 comprenant un dispositif de distribution 20 monté sur deux récipients 30 contenant des produits à mélanger extemporanément.There is shown in Figure 1 a dispensing assembly 10 comprising a dispensing device 20 mounted on two containers 30 containing products to be mixed extemporaneously.

Comme on le voit plus particulièrement sur la figure 2, le dispositif de distribution 20 comporte un collier d'assemblage 40 destiné à solidariser les deux récipients 30, un élément d'actionnement 50, un embout de distribution 60 ainsi qu'un organe intermédiaire 70 dont le rôle sera précisé plus loin. Chacun de ces éléments constitutifs du dispositif de distribution peut être réalisé par moulage, notamment en matériau thermoplastique tel qu'en polypropylène.As seen more particularly in Figure 2, the dispensing device 20 comprises an assembly collar 40 for securing the two containers 30, an actuating element 50, a dispensing nozzle 60 and an intermediate member 70 whose role will be explained later. Each of these constituent elements of the dispensing device can be made by molding, in particular of thermoplastic material such as polypropylene.

Chaque récipient 30 est dans l'exemple de réalisation décrit du type aérosol pressurisé et comporte une valve pourvue d'une tige d'actionnement 31, comme on peut le voir sur la figure 2. La valve est maintenue par sertissage sur une collerette 32 du récipient.Each container 30 is in the described embodiment of the pressurized aerosol type and comprises a valve provided with an actuating rod 31, as can be seen in FIG. 2. The valve is held by crimping on a collar 32 of the container.

La tige d'actionnement 31 est creuse et la distribution de produit s'effectue, lorsque la tige d'actionnement est basculée, au travers de celle-ci.The actuating rod 31 is hollow and the product distribution is effected, when the actuating rod is tilted, therethrough.

Le collier d'assemblage 40 est prévu pour maintenir ensemble les deux récipients, en particulier lors de l'alimentation des différentes pièces sur la chaîne d'assemblage.The assembly collar 40 is provided to hold the two containers together, in particular during the feeding of the various parts on the assembly line.

Le collier d'assemblage 40 comporte une paroi plane 41 traversée par deux ouvertures circulaires 42 prévues pour recevoir chacune l'extrémité supérieure d'un des récipients 30.The assembly collar 40 has a flat wall 41 traversed by two circular openings 42 provided for receiving each the upper end of one of the containers 30.

La paroi plane 41 est entourée à sa périphérie par une paroi d'habillage 43 qui s'étend de part et d'autre de cette paroi plane 41 de façon perpendiculaire. La paroi d'habillage 43 comporte deux portions droites 43a et parallèles entre elles qui se relient par deux portions en arc de cercle 43b. Chacune des deux portions en arc de cercle 43b se prolonge, sous la paroi plane 41, par une portion en arc de cercle complémentaire de manière à former deux jupes tubulaires 44. Chaque jupe tubulaire 44 comporte une section transversale circulaire et entoure une des ouvertures circulaires 42. Chaque jupe tubulaire 44 comporte, sur sa surface radialement interne, un bourrelet annulaire 45, visible sur la figure 5, apte à s'encliqueter sous la collerette 32 du récipient correspondant de manière à fixer le collier sur chaque récipient. Chaque jupe tubulaire 44 se termine par une extrémité biseautée 44a pour faciliter son montage sur les récipients.The plane wall 41 is surrounded at its periphery by a cladding wall 43 which extends on either side of this flat wall 41 perpendicularly. The covering wall 43 comprises two straight portions 43a and parallel to each other which connect by two arcuate portions 43b. Each of the two arcuate portions 43b is extended, under the flat wall 41, by a complementary arcuate portion so as to form two tubular skirts 44. Each tubular skirt 44 has a circular cross section and surrounds one of the circular openings 42. Each tubular skirt 44 has on its radially inner surface, an annular bead 45, visible in Figure 5, adapted to snap under the flange 32 of the corresponding container so as to fix the collar on each container. Each tubular skirt 44 ends with a beveled end 44a to facilitate its mounting on the containers.

Un bourrelet 46 est prévu sur la surface interne de la portion de la paroi d'habillage 43 située au dessus de la paroi plane 41 pour permettre l'accrochage de l'embout de distribution 60.A bead 46 is provided on the inner surface of the portion of the covering wall 43 located above the flat wall 41 to allow attachment of the dispensing tip 60.

Un décrochement radial 47 est formé sur la surface radialement externe de la paroi d'habillage 43 dont la fonction sera expliquée ultérieurement.A radial recess 47 is formed on the radially outer surface of the cladding wall 43 whose function will be explained later.

Pour distribuer le produit de manière relativement précise, le dispositif 20 comporte un embout de distribution 60 lequel, une fois que le dispositif est monté sur les récipients, permet une sortie du produit selon une direction sensiblement perpendiculaire à l'axe principal des récipients, par deux orifices de distribution 62a et 62b.To distribute the product in a relatively precise manner, the device 20 comprises a dispensing nozzle 60 which, once the device is mounted on the containers, allows an outlet of the product in a direction substantially perpendicular to the main axis of the containers, by two dispensing orifices 62a and 62b.

L'embout de distribution 60 est de forme allongée et s'étend selon un axe principal qui est incliné vers le haut du dispositif lorsqu'il est en place sur les récipients et que l'élément d'actionnement est au repos, comme on le voit sur la figure 3. L'embout comporte une section transversale par rapport à son axe principal de forme rectangulaire qui s'agrandit jusqu'à son extrémité libre qui délimite les orifices de distribution, de manière telle que l'embout s'évase en direction des orifices de distribution.The dispensing nozzle 60 is of elongated shape and extends along a main axis that is inclined upwardly of the device when it is in place on the containers and that the actuating element is at rest, as it is FIG. 3 shows a cross-section with respect to its main axis of rectangular shape which expands to its free end which delimits the dispensing orifices, in such a way that the endpiece direction of the dispensing orifices.

L'embout de distribution 60 est agencé pour canaliser séparément les produits jusqu'à son extrémité libre. A cet effet, l'embout 60 comporte une cloison 61 qui délimite deux conduits 61 a et 61b débouchant par les deux orifices de distribution 62a et 62b de manière à permettre la distribution des deux produits séparément. Les deux orifices 62a et 62b sont de forme carrée.The dispensing nozzle 60 is arranged to channel the products separately to its free end. For this purpose, the tip 60 comprises a partition 61 which defines two ducts 61a and 61b opening through the two distribution orifices 62a and 62b so as to allow the distribution of the two products separately. The two orifices 62a and 62b are of square shape.

A l'opposé des orifices, l'embout 60 se prolonge par une embouchure 63 s'étendant parallèlement à l'axe principal des tiges de valves. L'embouchure 63 a une section transversale à son axe principal circulaire. L'embouchure 63 est également délimitée en deux compartiments sur sa partie supérieure par la cloison 61 qui se prolonge jusqu'à la partie supérieure de l'embouchure 63.Opposite the orifices, the tip 60 is extended by a mouth 63 extending parallel to the main axis of the valve stems. The mouth 63 has a cross section at its main circular axis. The mouth 63 is also delimited in two compartments on its upper part by the partition 61 which extends to the upper part of the mouth 63.

L'embouchure 63 est prévue pour s'emmancher sur un conduit de sortie de l'élément intermédiaire, lequel, on le verra en détail par la suite, est une pièce intermédiaire permettant de faire communiquer l'embout 60 avec les récipients.The mouth 63 is provided to be fitted on an outlet duct of the intermediate element, which, as will be seen in detail later, is an intermediate piece for communicating the tip 60 with the containers.

L'embout de distribution 60 est maintenu sur le collier d'assemblage par une jupe de montage 90 destinée à venir s'insérer dans la partie supérieure de la paroi d'habillage 43 du collier d'assemblage, à l'intérieur de celle-ci. La jupe de montage 90 comporte un bourrelet 91 sur sa surface externe destiné à coopérer avec le bourrelet 46 prévu sur la paroi d'habillage 36 du collier d'assemblage.The dispensing nozzle 60 is held on the assembly collar by a mounting skirt 90 intended to be inserted into the upper part of the cladding wall 43 of the assembly collar, inside the assembly collar. this. The mounting skirt 90 has a bead 91 on its outer surface intended to cooperate with the bead 46 provided on the casing wall 36 of the assembly collar.

Comme la paroi d'habillage 43, la jupe de montage 90 comporte deux parois droites et parallèles entre elles qui sont reliées entre elles par deux portions en arc de cercle. L'une des deux parois droites est décalée vers l'extérieur de la jupe et se prolonge au dessus du reste de la jupe par une paroi frontale 92 qui, comme on le verra par la suite, prolonge un capot extérieur. En particulier, la portion inférieure 92a de la paroi frontale 92 est prévue pour venir se glisser à l'extérieur de la paroi d'habillage 43 du collier d'assemblage, contrairement au reste de la jupe de montage 90.Like the cladding wall 43, the mounting skirt 90 comprises two parallel straight walls which are interconnected by two arcuate portions. One of the two straight walls is shifted outwardly of the skirt and extends above the rest of the skirt by a front wall 92 which, as will be seen later, extends an outer cover. In particular, the lower portion 92a of the front wall 92 is provided to slide on the outside of the cladding wall 43 of the assembly collar, in contrast to the rest of the mounting skirt 90.

Cette paroi frontale 92 comporte, sur sa partie supérieure, une échancrure 92b qui permet le passage de l'embout de distribution 60.This front wall 92 has, on its upper part, a notch 92b which allows the passage of the dispensing nozzle 60.

La jupe de montage 90 comporte également un décrochement radial 93, sa partie supérieure étant en retrait de sa partie inférieure. La partie supérieure de la jupe de montage 90 se prolonge radialement vers l'intérieur par une paroi 94 transversale à la jupe. Cette paroi 94 comporte des fentes 95 dont la fonction sera expliquée plus loin.The mounting skirt 90 also comprises a radial recess 93, its upper part being set back from its lower part. The upper part of the mounting skirt 90 is extended radially inwardly by a wall 94 transverse to the skirt. This wall 94 has slots 95 whose function will be explained later.

L'embout de distribution 60 est relié à la jupe de montage 90 par une bande souple 96 en forme de S qui s'étend entre la jupe de montage 90 et l'embouchure 63, à l'opposé des orifices de distribution. Cette bande souple 96 autorise le mouvement de l'embout 60 par rapport à la jupe de montage 90.The dispensing tip 60 is connected to the mounting skirt 90 by an S-shaped flexible band 96 extending between the mounting skirt 90 and the mouth 63, opposite the dispensing orifices. This flexible band 96 allows movement of the tip 60 relative to the mounting skirt 90.

Pour éviter le ballottement de l'embout de distribution 60 lors de son assemblage sur les récipients, on prévoit avantageusement une languette 97 qui relie l'embout 60 à la paroi frontale 92, juste en dessous de l'embout. La languette 97 doit être suffisamment rigide pour éviter un mouvement trop important de l'embout par rapport à la jupe de montage 90 mais suffisamment souple pour autoriser le basculement de l'embout lors de la manoeuvre de l'élément d'actionnement. La languette peut en effet se courber, comme on le voit à la figure 4, pour permettre à l'embout 60 de basculer vers l'avant.To avoid the sloshing of the dispensing nozzle 60 during its assembly on the containers, it is advantageously provided a tab 97 which connects the tip 60 to the front wall 92, just below the tip. Tab 97 must be rigid enough to prevent movement too much important tip of the nozzle relative to the mounting skirt 90 but flexible enough to allow tilting of the tip during the operation of the actuating element. The tongue can indeed bend, as shown in Figure 4, to allow the tip 60 to swing forward.

Au lieu d'utiliser une languette 97 pour éviter le ballottement de l'embout 60 lors de son assemblage, on peut en variante prévoir deux picots 197 de part et d'autre de l'embout 60, chaque picot 197 reliant l'embout 60 à la paroi frontale 92 comme on l'a illustré à la figure 8. Ces picots sont suffisants pour maintenir l'embout en position fixe par rapport à la jupe de montage 90, mais sont aptes à se rompre au premier actionnement de l'élément d'actionnement pour autoriser le basculement de l'embout relativement à la paroi frontale 92.Instead of using a tongue 97 to prevent sloshing of the tip 60 during its assembly, one can alternatively provide two pins 197 on either side of the tip 60, each pin 197 connecting the tip 60 to the front wall 92 as illustrated in Figure 8. These pins are sufficient to maintain the nozzle in a fixed position relative to the mounting skirt 90, but are able to break at the first actuation of the element actuating device to allow tilting of the tip relative to the front wall 92.

A chaque extrémité arrondie de la jupe de montage 90, à l'intérieur de la jupe, des parois formant butée sont prévues pour faciliter le positionnement de l'élément intermédiaire 70 par rapport à l'embout de distribution. En particulier, une butée 98 est prévue à chaque extrémité arrondie et deux autres parois 99, perpendiculaires à ces premières butées 90, sont également prévues à proximité de chaque extrémité arrondie de la jupe de montage.At each rounded end of the mounting skirt 90, inside the skirt, abutment walls are provided to facilitate positioning of the intermediate member 70 relative to the dispensing tip. In particular, a stop 98 is provided at each rounded end and two other walls 99, perpendicular to these first stops 90, are also provided near each rounded end of the mounting skirt.

Pour permettre l'écoulement du produit provenant de chaque récipient jusqu'à l'embout de distribution, on utilise un organe intermédiaire 70 destiné à faire communiquer les tiges d'actionnement 31 des récipients 30 avec l'embout de distribution 60.To allow the flow of the product from each container to the dispensing nozzle, an intermediate member 70 is used for communicating the actuating rods 31 of the containers 30 with the dispensing nozzle 60.

L'organe intermédiaire 70 comporte, comme on peut le voir plus particulièrement sur les figures 5 et 6, une partie tubulaire 71 allongée selon un axe Y, ouverte à ses deux extrémités, deux jupes 72a et 72b d'axe W perpendiculaire à l'axe Y, chaque jupe communiquant avec l'intérieur de la partie allongée 71, et un conduit de sortie 73 d'axe principal Z perpendiculaire à l'axe Y, situé dans un plan médian à égale distance des jupes 72a et 72b.The intermediate member 70 comprises, as can be seen more particularly in Figures 5 and 6, a tubular portion 71 elongate along an axis Y, open at both ends, two skirts 72a and 72b of axis W perpendicular to the Y axis, each skirt communicating with the interior of the elongated portion 71, and an outlet pipe 73 of main axis Z perpendicular to the axis Y, located in a median plane equidistant from the skirts 72a and 72b.

Une cloison 74 sépare le conduit de sortie 73 en deux compartiments et se prolonge dans la partie tubulaire 71 pour la séparer en deux de manière à former deux canaux intérieurs 75a et 75b permettant l'écoulement séparé des deux produits.A partition 74 separates the outlet duct 73 into two compartments and extends into the tubular portion 71 to separate it in two so as to forming two inner channels 75a and 75b allowing the separate flow of the two products.

Chaque jupe 72a et 72b présente une première portion 76a de sa surface intérieure qui est conique de manière à faciliter son emmanchement sur la tige d'actionnement 31 du récipient correspondant. La première portion 76a se raccorde, par une portion droite dans laquelle peut s'ajuster de manière étanche la tige d'actionnement 31, à un épaulement 76b contre lequel peut venir en appui l'extrémité supérieure 31a de la tige d'actionnement.Each skirt 72a and 72b has a first portion 76a of its inner surface which is conical so as to facilitate its fitting on the actuating rod 31 of the corresponding container. The first portion 76a is connected by a straight portion in which the actuating rod 31 can fit sealingly to a shoulder 76b against which the upper end 31a of the actuating rod can bear.

La partie tubulaire allongée 71 de l'organe intermédiaire 70 est fermée à ses extrémités au moyen d'une buse 77 dont l'orifice de sortie est bouché, comme on peut le voir sur la figure 5. Bien entendu, tout autre bouchon pourrait être utilisé pour fermer ces extrémités.The elongated tubular portion 71 of the intermediate member 70 is closed at its ends by means of a nozzle 77 whose outlet orifice is plugged, as can be seen in FIG. 5. Of course, any other plug could be used to close these ends.

L'organe intermédiaire 70 comporte inférieurement, du même côté que les jupes 72a et 72b, une nervure de rigidification 78 centrale, dont les extrémités sont espacées des jupes 72a et 72b et deux nervures longitudinales 79 s'étendant chacune sur toute la longueur de l'organe intermédiaire 70.The intermediate member 70 has, on the same side as the skirts 72a and 72b, a central stiffening rib 78, the ends of which are spaced apart from the skirts 72a and 72b and two longitudinal ribs 79 each extending over the entire length of the barrel. intermediate member 70.

Lorsque l'organe intermédiaire 70 est en place dans le dispositif, les jupes 72a et 72b viennent se positionner au centre des jupes de montage respectives 44 du collier d'assemblage.When the intermediate member 70 is in place in the device, the skirts 72a and 72b are positioned in the center of the respective mounting skirts 44 of the assembly collar.

Pour protéger l'embout de distribution 60, un capot extérieur 80 vient coiffer l'embout de distribution et l'élément intermédiaire.To protect the dispensing nozzle 60, an outer cover 80 caps the dispensing nozzle and the intermediate element.

Le capot 80 comporte une coque 81 dont la partie inférieure vient entourer la portion supérieure de la jupe d'habillage 43 du collier d'assemblage et dont le bord 81 a vient en butée contre le décrochement radial 47 de la jupe d'habillage du collier.The cover 80 comprises a shell 81 whose lower part surrounds the upper portion of the dressing skirt 43 of the assembly collar and whose edge 81 has abuts against the radial recess 47 of the collar dressing skirt. .

La coque 81 est ouverte dans sa partie supérieure de manière à loger l'élément d'actionnement 50.The shell 81 is open in its upper part so as to accommodate the actuating element 50.

La coque 81 est également ouverte sur sa partie frontale pour laisser déboucher les orifices de sortie du produit 62a et 62b, cette partie ouverte étant en partie fermée par la paroi frontale 92 prévue sur la jupe de montage 90 de l'embout. Seule une ouverture correspondant à l'extrémité libre de l'embout de distribution est prévue.The shell 81 is also open on its front part to allow the outlet openings of the product 62a and 62b to open, this open portion being partly closed by the end wall 92 provided on the mounting skirt 90 of the nozzle. Only an opening corresponding to the free end of the dispensing nozzle is provided.

Au dessus de l'ouverture avant, le capot se termine par une avancée 82 qui vient épouser la forme de l'extrémité libre de l'embout de distribution 50 lorsque l'élément d'actionnement est au repos.Above the front opening, the hood ends with an advance 82 which comes to follow the shape of the free end of the dispensing nozzle 50 when the actuating element is at rest.

Un volet 83 est prévu au dessus de cette avancée 92 pour pouvoir fermer les orifices de distribution 62a et 62b et empêcher les impuretés d'entrer dans l'embout de distribution. Le volet 83 est articulé sur le capot par une charnière film 83a, notamment une charnière à effet ressort.A flap 83 is provided above this advanced 92 to be able to close the dispensing orifices 62a and 62b and prevent impurities from entering the dispensing nozzle. The flap 83 is hinged to the hood by a film hinge 83a, in particular a spring hinge.

Avantageusement, le volet 83 comporte, sur sa face qui est en regard des orifices de distribution en position fermée, deux éléments en saillie 84 de forme carrée. Ces éléments en saillie 84 viennent se loger dans l'extrémité des conduits 61 a et 61 b de l'embout de distribution, de sorte qu'en position fermée du volet 83, les éléments en saillie 84 empêchent l'embout de distribution de se déplacer relativement au volet et donc aussi relativement au reste du capot. Le volet 83 empêche ainsi le déplacement de l'organe intermédiaire 70 et donc celui de l'élément d'actionnement 50. On empêche ainsi un actionnement accidentel de l'élément d'actionnement qui pourrait provoquer la distribution des produits.Advantageously, the flap 83 comprises, on its face which faces the dispensing orifices in the closed position, two projecting elements 84 of square shape. These projecting elements 84 are housed in the end of the ducts 61a and 61b of the dispensing nozzle, so that in the closed position of the flap 83, the projecting elements 84 prevent the dispensing nozzle from becoming move relative to the flap and therefore also relative to the rest of the hood. The flap 83 thus prevents the displacement of the intermediate member 70 and therefore that of the actuating element 50. This prevents accidental actuation of the actuating element which could cause the products to be dispensed.

Pour permettre la fixation du capot 80 sur le reste du dispositif des nervures verticales 85 visibles en partie à la figure 7, sont prévues sur la surface interne de la coque. Les nervures 85 comportent une extrémité 85a qui vient se loger dans chacune des fentes 95 de la jupe de montage de l'embout de distribution.To allow the attachment of the cover 80 to the rest of the device vertical ribs 85 visible in part in Figure 7, are provided on the inner surface of the shell. The ribs 85 have an end 85a which is housed in each of the slots 95 of the mounting skirt of the dispensing nozzle.

Le capot est réalisé d'un seul tenant avec l'élément d'actionnement 50, comme on peut le voir sur la figure 1 ou 2. En particulier, l'élément d'actionnement 50 est relié au capot par deux charnières film 51 qui permettent à l'élément d'actionnement de basculer autour d'un axe P. L'élément d'actionnement 50 comporte une surface d'appui 52 sur laquelle l'utilisateur peut appuyer pour faire pivoter l'élément d'actionnement 50 autour de l'axe P.The cover is made in one piece with the actuating element 50, as can be seen in Figure 1 or 2. In particular, the actuating element 50 is connected to the hood by two film hinges 51 which allow the actuating element to tilt about an axis P. The actuating element 50 has a bearing surface 52 on which the user can press to make pivoting the actuating element 50 around the axis P.

Comme on le voit plus particulièrement sur les figures 7 et 9, l'élément d'actionnement 50 comporte, sur son côté intérieur deux pattes rigides 53 espacées l'une de l'autre et destinées à venir en appui sur la partie tubulaire allongée 71 de l'organe intermédiaire 70 en deux zones d'appui 170a et 170b. Les efforts sont ainsi répartis de façon équilibrée sur l'organe intermédiaire. Chaque patte 53 comporte un bord incliné 53a qui est destiné à venir s'appliquer sur chaque zone d'appui de l'organe intermédiaire.As seen more particularly in Figures 7 and 9, the actuating element 50 comprises, on its inner side two rigid tabs 53 spaced apart from each other and intended to bear against the elongated tubular portion 71 of the intermediate member 70 in two bearing zones 170a and 170b. The forces are thus distributed in a balanced manner on the intermediate member. Each lug 53 has an inclined edge 53a which is intended to be applied to each bearing zone of the intermediate member.

Comme on le voit à la figure 9, la zone d'appui 170a est située à une distance de la jupe 72a de l'organe intermédiaire sensiblement identique à la distance entre la zone d'appui 170b et la jupe 72b.As seen in Figure 9, the bearing zone 170a is located at a distance from the skirt 72a of the intermediate member substantially identical to the distance between the bearing zone 170b and the skirt 72b.

Ainsi, lorsque l'on enfonce l'élément d'actionnement, l'organe intermédiaire est sollicité en deux zones espacées qui sont chacune à une même distance de chaque tige d'actionnement. On a ainsi plus de chance de basculer de façon identique chaque tige d'actionnement que lorsque l'on utilise une seule zone d'appui située sensiblement au centre de la portion allongée de l'organe intermédiaire.Thus, when driving the actuating element, the intermediate member is biased in two spaced zones which are each at the same distance from each actuating rod. It is thus more likely to switch identically each actuating rod that when using a single bearing zone located substantially in the center of the elongated portion of the intermediate member.

Selon une variante non illustrée, on peut prévoir que les deux pattes rigides 53 sont situées de manière telle qu'elles viennent en appui sur l'organe d'actionnement sensiblement dans l'axe des jupes 72a et 72b.According to a variant not illustrated, it can be provided that the two rigid tabs 53 are located such that they abut on the actuating member substantially in the axis of the skirts 72a and 72b.

En variante également, on peut prévoir que l'élément d'actionnement comporte plus de deux pattes, par exemple quatre, six ou plus.Alternatively also, it can be provided that the actuating element has more than two tabs, for example four, six or more.

Avantageusement, des picots d'inviolabilité, non visibles sur les figures, relient l'élément d'actionnement 50 au capot 80, de chaque côté de l'élément d'actionnement avant une première utilisation du dispositif. Ces picots se rompent au premier actionnement de l'élément d'actionnement.Advantageously, tamper pins, not visible in the figures, connect the actuating element 50 to the hood 80, on each side of the element actuation before a first use of the device. These pins break at the first actuation of the actuating element.

Pour mettre en place le dispositif de distribution sur les récipients 30, on dispose le collier d'assemblage sur les récipients 30 accolés, jusqu'à encliquetage du collier d'assemblage 40 sur les collerettes 32 des récipients 30.To set up the dispensing device on the containers 30, the assembly collar is placed on the contiguous containers 30 until the assembly collar 40 is snapped onto the collars 32 of the containers 30.

Parallèlement, on assemble l'embout de distribution 60 et l'élément intermédiaire en emmanchant l'embouchure 63 de l'embout 60 sur le conduit de sortie 73 de l'élément intermédiaire. On fixe ensuite la jupe de montage 90 de l'embout de distribution dans le collier d'assemblage 40 puis on vient coiffer l'ensemble avec le capot 80.Meanwhile, the dispensing nozzle 60 and the intermediate element are assembled by engaging the mouth 63 of the nozzle 60 on the outlet duct 73 of the intermediate element. The mounting skirt 90 of the dispensing nozzle is then fixed in the assembly collar 40 and the assembly is then capped with the cover 80.

Pour provoquer la distribution, l'utilisateur appuie sur la surface d'appui 52 de l'élément d'actionnement 50 dans le sens de la flèche F de la figure 4. L'élément d'actionnement 50 fait basculer l'élément intermédiaire 70 vers l'avant, ce qui a pour effet de faire également basculer les tiges de valve 31. Les efforts étant répartis de façon équilibrée sur l'organe intermédiaire, les deux tiges de valves 31 sont basculées de façon identique de sorte que la même quantité de produit peut quitter le canal intérieur de chaque tige de valve, circuler à l'intérieur de l'élément intermédiaire et gagner l'embout de distribution jusqu'à arriver à chaque orifice de sortie. Grâce à la présence de la bande souple 96, l'embout de distribution 60 bascule en même temps vers l'avant, son extrémité libre s'éloignant du capot 80 et aussi du volet. On évite ainsi de déposer du produit sur le capot et en particulier sur le volet.To cause dispensing, the user presses the bearing surface 52 of the actuating element 50 in the direction of the arrow F of FIG. 4. The actuating element 50 tilts the intermediate element 70 forward, which has the effect of also tilting the valve rods 31. The efforts being balanced in the intermediate member, the two valve stems 31 are tilted in an identical manner so that the same amount of product can leave the inner channel of each valve stem, circulate inside the intermediate element and gain the dispensing nozzle until reaching each outlet port. Thanks to the presence of the flexible band 96, the dispensing tip 60 tilts at the same time forward, its free end away from the hood 80 and also the flap. This avoids depositing product on the hood and in particular on the flap.

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'invention telle que revendiquée ci-après. En particulier, l'élément intermédiaire 70 et l'embout de distribution 60 peuvent ne pas comporter de cloison de manière à ce que les deux produits se mélangent avant d'arriver à l'orifice de distribution. Les produits délivrés par ces derniers se mélangent à l'intérieur de la partie tubulaire allongée de l'élément intermédiaire en arrivant au pied du conduit de sortie. Le mélange atteint ensuite l'embout de distribution pour être distribué sur les cheveux par exemple.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter. In particular, the intermediate element 70 and the dispensing nozzle 60 may have no partition so that the two products are mixed before arriving at the dispensing orifice. The products delivered by the latter are mixed inside the elongated tubular part of the element intermediate when arriving at the foot of the exit pipe. The mixture then reaches the dispensing tip to be distributed on the hair, for example.
