Description

La présente invention concerne un dispositif mélangeur pour le conditionnement et la distribution d'un mélange de deux produits isolés l'un de l'autre avant l'opération de distribution.The present invention relates to a mixing device for packaging and dispensing a mixture of two products isolated from each other before the dispensing operation.

On a déjà proposé de nombreux dispositifs permettant de conditionner isolément sous un même emballage deux produits que l'on désire mélanger juste avant l'emploi.Numerous devices have already been proposed making it possible to condition two products, which one wishes to mix just before use, in a single package.

C'est le cas notamment du flacon mélangeur décrit dans EP-A2-0 243 730 qui comprend deux compartiments disposés axialement l'un à la suite de l'autre, un obturateur fermant, pendant le stockage, la zone de raccordement des deux compartiments ; l'obturateur est porté par un bouchon monté à rotation à l'extrémité du flacon par une liaison à rampes, en sorte que, lorsque le bouchon est tourné par rapport au flacon, l'obturateur libère la communication entre les deux compartiments et les deux produits peuvent être mélangés ; le bouchon porte un bec verseur obturé par une pièce de fermeture reliée au bec par une zone sécable. EP-A-0 063 759 concerne un dispositif dans lequel deux récipients sont montés dans une enveloppe commune, suivant le préambule de la revendication 1. Le premier récipient est fixe et la tête de distribution est toujours disposée à l'extérieur de l'enveloppe commune. Seul l'un des récipients est monté coulissant dans l'enveloppe de façon à se rapprocher du premier récipient fixe et de mettre en communication les deux récipients. Ces flacons mélangeurs présentent l'inconvénient de ne pas présenter une sécurité d'utilisation, le flacon pouvant être utilisé sans que le mélange des deux produits ait été effectué.This is particularly the case for the mixing bottle described in EP-A2-0 243 730 which comprises two compartments arranged axially one after the other, a shutter closing, during storage, the connection zone of the two compartments ; the shutter is carried by a stopper rotatably mounted at the end of the bottle by a ramp connection, so that when the stopper is turned relative to the bottle, the shutter releases communication between the two compartments and the two products can be mixed; the stopper carries a pouring spout closed by a closure piece connected to the spout by a breakable zone. EP-A-0 063 759 relates to a device in which two containers are mounted in a common envelope, according to the preamble of claim 1. The first container is fixed and the dispensing head is always disposed outside the envelope common. Only one of the containers is slidably mounted in the envelope so as to approach the first fixed container and to put the two containers in communication. These mixing bottles have the drawback of not being safe to use, since the bottle can be used without mixing of the two products.

La présente invention a pour objet un dispositif mélangeur de réalisation simple et ne présentant pas l'inconvénient ci-dessus.The present invention relates to a mixing device which is simple to make and does not have the above drawback.

Ainsi, selon l'invention, un dispositif mélangeur d'au moins deux produits contenus chacun dans un récipient, l'un des récipients, ou premier récipient, avant un volume adapté à recevoir le produit contenu dans l'autre récipient, ou deuxième récipient, pour obtenir le mélange des deux produits, le premier récipient comporte sa partie supérieure un bouton-poussoir équipé d'une buse l'actionnement permet de faire sortir le mélange du premier récipient à travers la buse, des moyens de communication obturables étant prévus entre les deux récipients, les deux récipients étant portés par une enveloppe commune dans laquelle le deuxième récipient peut coulisser par rapport au premier récipient entre deux positions, une position dite d'éloignement pour laquelle les deux récipients ne sont pas en communication et une position dite de rapprochement pour laquelle les moyens de communication sont actionnés et les deux récipients sont en communication, est caractérisé par le fait que l'enveloppe est fermée à sa partie supérieure par un couvercle et qu'un moyen compressible maintient momentanément, pendant le stockage, le premier récipient en éloignement du couvercle de l'enveloppe, le bouton-poussoir du premier récipient étant à l'intérieur de l'enveloppe.Thus, according to the invention, a device for mixing at least two products each contained in a container, one of the containers, or first container, before a volume adapted to receive the product contained in the other container, or second container. , to obtain the mixture of the two products, the first container has its upper part a push button equipped with a nozzle actuation allows the mixture to come out of the first container to through the nozzle, closable communication means being provided between the two containers, the two containers being carried by a common envelope in which the second container can slide relative to the first container between two positions, a so-called remote position for which the two containers are not in communication and a so-called approach position for which the communication means are actuated and the two containers are in communication, is characterized in that the envelope is closed at its upper part by a cover and that compressible means temporarily maintains, during storage, the first container away from the cover of the envelope, the push button of the first container being inside the envelope.

Avantageusement, l'enveloppe a une longueur telle que, dans la position d'éloignement des deux récipients, le premier récipient est tout entier contenu dans l'enveloppe, y compris son bouton-poussoir, tandis que le deuxième récipient dépasse de l'enveloppe, alors que, dans la position de rapprochement des deux récipients, le bouton-poussoir du premier récipient dépasse de l'enveloppe et est dès lors accessible de l'extérieur de l'enveloppe.Advantageously, the envelope has a length such that, in the position away from the two containers, the first container is entirely contained in the envelope, including its push button, while the second container protrudes from the envelope , whereas, in the position for bringing the two containers closer together, the push-button of the first container protrudes from the envelope and is therefore accessible from outside the envelope.

De préférence, l'enveloppe est constituée d'une paroi cylindrique fermée à sa partie supérieure d'un couvercle dans lequel est ménagé un orifice dont la section est égale, au jeu près, à la section du bouton-poussoir du premier récipient, la partie inférieure de l'enveloppe étant munie d'un passage au plus égal à la section du deuxième récipient.Preferably, the envelope consists of a cylindrical wall closed at its upper part with a cover in which is formed an orifice whose section is equal, apart from play, to the section of the push button of the first container, the lower part of the envelope being provided with a passage at most equal to the section of the second container.

Avantageusement, des moyens d'accrochage sont prévus pour immobiliser l'ensemble dans la position de rapprochement des deux récipients, le bouton-poussoir du premier récipient émergeant de l'enveloppe en étant accessible de l'extérieur de l'enveloppe ; selon une forme de réalisation, les moyens d'accrochage comprennent un redent prévu sur le deuxième récipient et dans lequel vient se loger la bordure de la partie inférieure de l'enveloppe définissant le passage.Advantageously, hooking means are provided for immobilizing the assembly in the position for bringing the two containers closer together, the push-button of the first container emerging from the envelope being accessible from the exterior of the envelope; according to one embodiment, the attachment means comprise a recess provided on the second container and in which is housed the edge of the lower part of the envelope defining the passage.

En variante, l'enveloppe a une longueur telle que, quelle que soit la position des deux récipients, les deux récipients sont contenus dans l'enveloppe qui retient à sa partie inférieure un poussoir faisant saillie à l'extérieur de l'enveloppe et coopérant avec le deuxième récipient.As a variant, the envelope has a length such that, whatever the position of the two containers, the two containers are contained in the envelope which retains a pusher at its lower part projecting outside the envelope and cooperating with the second container.

Selon une autre variante, l'enveloppe est en deux pièces, une pièce supérieure et une pièce inférieure, emboîtées l'une dans l'autre, avec possibilité de déplacement axial relatif de l'une des pièces par rapport à l'autre, l'enveloppe comportant un fond constitué par le fond de la pièce inférieure, et chacun des deux récipients étant situé à l'intérieur de l'une des pièces.According to another variant, the envelope is in two parts, an upper part and a lower part, one nested in the other, with the possibility of relative axial displacement of one of the parts with respect to the other, the envelope comprising a bottom formed by the bottom of the lower part, and each of the two receptacles being located inside one of the pieces.

Avantageusement, quelle que soit la variante, un moyen compressible est prévu dans l'enveloppe entre les deux récipients.Advantageously, whatever the variant, a compressible means is provided in the envelope between the two containers.

Les moyens de communication entre les deux récipients sont du type pompe manuelle ; en variante, les moyens de communication sont du type à valve, un fluide propulseur sous pression étant prévu dans le deuxième récipient.The means of communication between the two containers are of the manual pump type; alternatively, the communication means are of the valve type, a pressurized propellant being provided in the second container.

Le bouton-poussoir du premier récipient actionne une pompe manuelle ; en variante, le bouton-poussoir met en oeuvre une valve, le premier récipient étant rempli d'un fluide propulseur sous une pression inférieure à la pression du fluide propulseur présent dans le deuxième récipient.The push-button of the first container activates a manual pump; alternatively, the push button implements a valve, the first container being filled with a propellant fluid under a pressure lower than the pressure of the propellant fluid present in the second container.

Lorsque l'ensemble est conçu pour une utilisation tête en haut, l'un au moins des deux récipients est doté d'un tube plongeur.When the assembly is designed for head-up use, at least one of the two containers has a dip tube.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire, maintenant, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

Le premier récipient 10, dans l'exemple représenté, est un bidon aérosol classique dont la paroi supérieure 19 porte une valve 12 actionnable par un bouton-poussoir 15 muni d'une buse de distribution 16 ; la valve 12 est reliée à un tube plongeur 13 ; le volume 14 du récipient 10, au dessus du niveau du produit 11, est occupé par un fluide propulseur sous pression.The first container 10, in the example shown, is a conventional aerosol can, the upper wall 19 of which carries a valve 12 actuable by a push button 15 provided with a dispensing nozzle 16; the valve 12 is connected to a dip tube 13; the volume 14 of the container 10, above the level of the product 11, is occupied by a propellant fluid under pressure.

Le deuxième récipient 20, tel que représenté, est du même genre que le récipient 10 : sa paroi supérieure 29 porte une valve 22 reliée à un tube plongeur 23 ; le volume 24 du récipient 20, au dessus du niveau du produit 21, est occupé par un fluide propulseur sous une pression supérieure à la pression du fluide propulseur dans le volume 14 du premier récipient 10.The second container 20, as shown, is of the same kind as the container 10: its upper wall 29 carries a valve 22 connected to a dip tube 23; the volume 24 of the container 20, above the level of the product 21, is occupied by a propellant fluid under a pressure greater than the pressure of the propellant fluid in the volume 14 of the first container 10.

Les deux récipients 10 et 20 sont disposés l'un au dessus de l'autre dans une enveloppe commune 30 ; des moyens de communication obturable sont prévus entre les deux récipients 10 et 20 : ils consistent en une tige de commande 18 de la valve 22 du deuxième récipient 20, ladite tige de commande 18, tubulaire comme connu en soi, étant portée par un poussoir 17, solidaire du fond du premier récipient 10 et muni d'un canal, non représenté, en communication, d'une part, avec la tige 18, et, d'autre part, avec l'intérieur du premier récipient 10 ; dans la position relative dite d'éloignement des deux récipients 10 et 20, représentée sur la figure 1, la valve 22 est fermée ; lorsque les deux récipients 10 et 20 sont rapprochés l'un de l'autre, dans les conditions décrites ci-après, vers une position dite de rapprochement, telle que représentée sur la figure 2, la tige de commande 18 pénètre dans la valve 22 qu'elle ouvre, et le produit 21 du deuxième récipient 20, sous l'action du fluide propulseur présent dans ce deuxième récipient 20, rejoint le premier récipient 10 à travers le tube plongeur 23, la valve 22 ouverte, la tige 18 et le canal du poussoir 17, la pression du fluide propulseur présent dans le deuxième récipient 20 étant supérieure à celle du fluide dans le premier récipient 10.The two containers 10 and 20 are arranged one above the other in a common envelope 30; closable communication means are provided between the two containers 10 and 20: they consist of a control rod 18 of the valve 22 of the second container 20, said control rod 18, tubular as known per se, being carried by a pusher 17 , integral with the bottom of the first container 10 and provided with a channel, not shown, in communication, on the one hand, with the rod 18, and, on the other hand, with the interior of the first container 10; in the relative position known as the separation of the two containers 10 and 20, shown in FIG. 1, valve 22 is closed; when the two containers 10 and 20 are brought towards each other, under the conditions described below, towards a so-called approach position, as shown in FIG. 2, the control rod 18 enters the valve 22 that it opens, and the product 21 of the second container 20, under the action of the propellant fluid present in this second container 20, joins the first container 10 through the dip tube 23, the valve 22 open, the rod 18 and the channel of the pusher 17, the pressure of the propellant fluid present in the second container 20 being greater than that of the fluid in the first container 10.

L'enveloppe commune 30 est constituée d'une paroi cylindrique fermée, à sa partie supérieure, d'un couvercle 35 ; un orifice 31 est ménagé dans le couvercle 35 ; l'orifice 31 est situé, lorsque l'ensemble est monté, au droit du bouton-poussoir 15 du premier récipient 10, la section de l'orifice 31 étant égale, au jeu de montage près, à la section du bouton-poussoir 15.The common envelope 30 consists of a closed cylindrical wall, at its upper part, with a cover 35; an orifice 31 is formed in the cover 35; the orifice 31 is located, when the assembly is mounted, in line with the push button 15 of the first container 10, the section of the orifice 31 being equal, apart from the mounting clearance, to the section of the push button 15 .

Du côté opposé au couvercle 35, l'enveloppe 30 est munie d'un passage 33 pour le deuxième récipient 20 ; le passage 33 est défini par la bordure de la partie inférieure 32 de l'enveloppe 33, en forme de collerette, dans laquelle le deuxième récipient 20 est monté serré.On the side opposite to the cover 35, the envelope 30 is provided with a passage 33 for the second container 20; the passage 33 is defined by the edge of the lower part 32 of the envelope 33, in the form of a collar, in which the second container 20 is mounted tight.

Un moyen compressible 34, sous forme d'un anneau en mousse, est disposé entre le couvercle 35 de l'enveloppe 30 et la paroi supérieure 19 du premier récipient 10, ledit moyen compressible 34 définissant la position du premier récipient 10 dans l'enveloppe 30 pendant le stockage de l'ensemble ; dans cette position, comme cela est visible sur la figure 1, le bouton-poussoir 15 affleure le couvercle 35 de l'enveloppe 30, de sorte qu'il n'est pas accessible de l'extérieur ; dans cette position de stockage, le deuxième récipient 20 est en éloignement du premier récipient 10, la valve 22 étant fermée, et le deuxième récipient 20 dépasse à la partie inférieure de l'enveloppe 30 qui le maintient dans cette position par serrage de sa collerette 32 sur la paroi extérieure du récipient 20.A compressible means 34, in the form of a foam ring, is disposed between the cover 35 of the envelope 30 and the upper wall 19 of the first container 10, said compressible means 34 defining the position of the first container 10 in the envelope 30 during storage of the assembly; in this position, as can be seen in FIG. 1, the push-button 15 is flush with the cover 35 of the casing 30, so that it is not accessible from the outside; in this storage position, the second container 20 is away from the first container 10, the valve 22 being closed, and the second container 20 protrudes from the lower part of the casing 30 which maintains it in this position by tightening its flange 32 on the outer wall of the container 20.

Pour utiliser le dispositif mélangeur selon la présente invention il suffit, en maintenant l'enveloppe 30, de pousser le deuxième récipient 20 à l'intérieur de l'enveloppe 30 : ce seul geste provoque, d'une part, le rapprochement des deux récipients 10 et 20, et donc l'ouverture de la valve 22 permettant au deuxième produit 21 de rejoindre le premier récipient 10, et, d'autre part, la sortie du bouton-poussoir 15 à travers l'orifice 31 de l'enveloppe 30, par coulissement des deux récipients 10 et 20 dans l'enveloppe 30 ; lors de ces opérations, l'anneau en mousse 34 est comprimé ; en fin de course, la bordure de la partie inférieure 32 de l'enveloppe 30 vient se détendre élastiquement dans une partie rétrécie du récipient 20 définissant un redent 36 permettant l'accrochage de l'enveloppe 30 sur le récipient 20 et le maintien de l'ensemble dans la position d'utilisation, telle que représentée sur la figure 2 ; ainsi, le mélange 41 des deux produits est réalisé, et une action, dès lors possible, sur le bouton-poussoir 15, permet la distribution de ce mélange 41 à travers la buse 16 du bouton-poussoir 15.To use the mixing device according to the present invention, it suffices, while maintaining the envelope 30, to push the second container 20 inside the envelope 30: this single gesture causes, on the one hand, the bringing together of the two containers 10 and 20, and therefore the opening of the valve 22 allowing the second product 21 to reach the first container 10, and, on the other hand, the exit of the push button 15 through the orifice 31 of the casing 30, by sliding the two containers 10 and 20 in the envelope 30; during these operations, the foam ring 34 is compressed; at the end of the race, the edge of the lower part 32 of the envelope 30 relaxes elastically in a narrowed part of the container 20 defining a recess 36 allowing the attachment of the envelope 30 to the container 20 and the maintenance of the 'together in the position of use, as shown in Figure 2; thus, the mixture 41 of the two products is produced, and action, as soon as possible, on the push button 15, allows the distribution of this mixture 41 through the nozzle 16 of the push button 15.

Ainsi, la sécurité d'utilisation est assurée : il est impossible d'actionner le bouton-poussoir 15 sans que le mélange 41 ne soit réalisé.Thus, safety in use is ensured: it is impossible to actuate the push button 15 without the mixture 41 being produced.

Dans l'exemple représenté, le premier récipient 10 est pressurisé, et le bouton-poussoir 15 actionne une valve 12 ; en variante, le premier récipient 10 est équipé d'une pompe manuelle.In the example shown, the first container 10 is pressurized, and the push-button 15 actuates a valve 12; alternatively, the first container 10 is equipped with a manual pump.

De même, le deuxième récipient 20 peut également être équipé d'une pompe, les moyens de communication entre les deux récipients étant, dans ce cas, actionnables par plusieurs déplacements successifs des deux récipients 10 et 20, l'un par rapport à l'autre, après quoi les moyens d'accrochage de l'enveloppe 30 sur le deuxième récipient 20 sont rendus opérationnels.Similarly, the second container 20 can also be equipped with a pump, the means of communication between the two containers being, in this case, actuable by several successive movements of the two containers 10 and 20, one relative to the other, after which the means for attaching the envelope 30 to the second container 20 are made operational.

On a utilisé comme moyen compressible 34 un anneau en mousse ; ce pourrait être également un ressort ou une pièce déformable irréversiblement.A foam ring was used as the compressible means 34; it could also be a spring or an irreversibly deformable part.

Selon la variante représentée sur la figure 3, lorsque les deux récipients 10 et 20 sont dans la position d'éloignement, le récipient 20 est contenu tout entier dans l'enveloppe 30 dont la partie inférieure 32 retient un poussoir 40 faisant saillie à l'extérieur de l'enveloppe et coopérant avec le récipient 20 ; dans cette variante, c'est le poussoir 40 qui porte le moyen d'accrochage 36, ici en forme de gorge, dans lequel vient se loger la bordure de la partie inférieure 32 de l'enveloppe 30.According to the variant shown in Figure 3, when the two containers 10 and 20 are in the remote position, the container 20 is entirely contained in the casing 30, the lower part 32 retains a pusher 40 projecting from the outside of the envelope and cooperating with the container 20; in this variant, it is the pusher 40 which carries the attachment means 36, here in the form of a groove, in which the edge of the lower part 32 of the envelope 30 is housed.

Selon les variantes représentées sur les figures 4 à 6, l'enveloppe 30 est en deux pièces 30A, 30B, une pièce supérieure 30A et une pièce inférieure 30B, emboitées l'une dans l'autre avec possibilité de déplacement axial relatif de l'une des pièces par rapport à l'autre pièce ; selon ces variantes, l'enveloppe comporte un fond 37 constitué par le fond de la pièce inférieure 30B et chacun des deux récipients 10, 20 est situé à l'intérieur de chacune des pièces 30A, 30B ; le déplacement axial relatif des deux pièces peut être obtenu par coulissement axial relatif et/ou par rotation relative.According to the variants shown in Figures 4 to 6, the casing 30 is in two parts 30A, 30B, an upper part 30A and a lower part 30B, nested one inside the other with the possibility of relative axial displacement of the one of the pieces in relation to the other piece; according to these variants, the envelope comprises a bottom 37 constituted by the bottom of the lower part 30B and each of the two containers 10, 20 is located inside each of the parts 30A, 30B; the relative axial displacement of the two parts can be obtained by relative axial sliding and / or by relative rotation.

Lorsque le déplacement est obtenu par coulissement, les deux pièces 30A, 30B, comme montré sur la figure 4, sont conformées de manière à assurer les deux positions relatives privilégiées de l'une par rapport à l'autre, correspondant aux positions dites d'éloignement et de rapprochement des deux récipients 10, 20 ; ces positions privilégiées sont par exemple assurées par une gorge 45 prévue sur l'une des pièces, la pièce supérieure 30A, qui coopère avec deux gorges 46, 47 espacées axialement prévues sur l'autre pièce, la pièce inférieure 30B.When the displacement is obtained by sliding, the two parts 30A, 30B, as shown in FIG. 4, are shaped so as to ensure the two preferred relative positions of one relative to the other, corresponding to the so-called positions of distance and approximation of the two containers 10, 20; these privileged positions are for example ensured by a groove 45 provided on one of the parts, the upper part 30A, which cooperates with two grooves 46, 47 axially spaced apart provided on the other part, the lower part 30B.

Lorsque le déplacement est obtenu par rotation, l'une des pièces, la pièce 30A comme montré sur la figure 5, présente un filet hélicoïdal 38 qui coopère avec un filet 39 également hélicoïdal que présente l'autre pièce 30B ; il est aussi possible d'obtenir un tel déplacement en dotant l'une des pièces, la pièce 30B comme montré sur la figure 6, d'au moins un pion ou index 41 coopérant avec une ouverture en forme de rampe 42 ménagée dans la paroi de l'autre pièce 30A, ladite rampe 42 s'étendant essentiellement en faisant un certain angle avec l'axe de l'enveloppe 30A-30B mais se terminant, à chacune de ses extrémités, selon une petite portion 43, 48 située dans un plan perpendiculaire à l'axe de l'enveloppe, cette disposition permettant de verrouiller les deux positions extrêmes relatives de l'une des pièces de l'enveloppe par rapport à l'autre ; selon cette variante, l'angle de la rampe 42 avec l'axe de l'enveloppe 30A-30B peut être prévu tel que, lorsque le pion ou index 41 coopère avec cette partie inclinée de la rampe 42, une sollicitation axiale d'une pièce 30B par rapport à l'autre pièce 30A conduit automatiquement à une rotation relative des deux pièces 30A, 30B, ce qui facilite la manoeuvre pour la mise en communication des deux récipients 10 et 20 ; il suffit ensuite de faire effectuer aux deux pièces 30A, 30B un léger mouvement de rotation relative pour verrouiller la position des deux récipients 10 et 20 en communication.When the displacement is obtained by rotation, one of the parts, the part 30A as shown in FIG. 5, has a helical thread 38 which cooperates with a thread 39 also helical that the other part 30B has; it is also possible to obtain such a displacement by providing one of the parts, the part 30B as shown in FIG. 6, with at least one pin or index finger 41 cooperating with a ramp-shaped opening 42 formed in the wall of the other part 30A, said ramp 42 extending essentially at a certain angle with the axis of the envelope 30A-30B but ending, at each of its ends, in a small portion 43, 48 located in a plane perpendicular to the axis of the envelope, this arrangement making it possible to lock the two relative extreme positions of one of the parts of the envelope with respect to the other; according to this variant, the angle of the ramp 42 with the axis of the casing 30A-30B can be provided such that, when the pin or index finger 41 cooperates with this inclined part of the ramp 42, an axial stress of a piece 30B relative to the other piece 30A automatically leads to a relative rotation of the two pieces 30A, 30B, which facilitates the maneuver for setting communication of the two containers 10 and 20; it then suffices to make the two parts 30A, 30B carry out a slight movement of relative rotation to lock the position of the two receptacles 10 and 20 in communication.

Quelle que soit la variante, avantageusement un moyen compressible, comme par exemple un anneau en mousse 44 analogue à l'anneau 34, est prévu dans l'enveloppe 30 entre les deux récipients 10, 20.Whatever the variant, advantageously a compressible means, such as for example a foam ring 44 similar to the ring 34, is provided in the casing 30 between the two containers 10, 20.
