Description

Distributeur de mélange de produit extemporané. Distributor of mix of extemporaneous product.
La présente invention concerne un distributeur permettant de distπbuer un mélange de produit fluide de manière extemporanee, c'est-à-dire que le mélange des divers constituants du produit fluide sont mélangés juste avant de pouvoir se servir du distπbuteur pour émettre une dose dudit mélange. Le distπbuteur comprend un organe de distribution, tel qu'une pompe, une valve ou même un bouchon, amsi que deux réservoirs séparés l'un de l'autre par une cloison commune.The present invention relates to a dispenser for distributing a mixture of fluid product in an extemporaneous manner, that is to say that the mixture of the various constituents of the fluid product are mixed just before they can be used by the distributor to deliver a dose of said mixture. . The distributor comprises a distribution member, such as a pump, a valve or even a plug, as well as two reservoirs separated from each other by a common partition.
L'utilisateur de ce distributeur, avant la première utilisation, doit effectuer une opération visant a mélanger les deux produits contenus dans les deux réservoirs par rupture ou enlèvement de la cloison commune. La rupture de cette cloison commune peut être effectuée de diverses manières.The user of this dispenser, before first use, must carry out an operation aimed at mixing the two products contained in the two tanks by breaking or removing the common partition. The rupture of this common partition can be carried out in various ways.
Le document US 4 821 923 propose par exemple un distπbuteur de mélange extemporané comprenant un premier réservoir sous la forme d'un flacon avec un col fileté, un second réservoir engagé dans le col du premier réservoir, et une pompe montée dans le second réservoir et communiquant avec le premier réservoir par l'intermédiaire d'un tube plongeur.Document US 4,821,923 proposes for example an extemporaneous mixing distributor comprising a first tank in the form of a bottle with a threaded neck, a second tank engaged in the neck of the first tank, and a pump mounted in the second tank and communicating with the first tank via a dip tube.
A l'état initial, le second réservoir est déjà en place à l'intéπeur du col du premier réservoir, et les deux réservoirs sont isolés l'un de l'autre par une paroi cassable. Cette paroi cassable est solidaire du tube plongeur. D'ailleurs, le second réservoir et le tube plongeur sont réalisés d'une seule pièce en matière plastique moulée. La paroi cassable définit une zone de momdre résistance favoπsant la rupture à cet endroit. Le second réservoir obture le premier réservoir, et un bouchon vient obturer le second réservoir en pπse filetée sur le col fileté du premier réservoir. La pompe n'est alors pas en place sur le distributeur. Le distπbuteur est donc vendu avec la pompe à part. Cela nécessite un emballage spécial. De plus, il y a un risque de salir ou d'abîmer la pompe en la manipulant.In the initial state, the second tank is already in place inside the neck of the first tank, and the two tanks are isolated from each other by a breakable wall. This breakable wall is integral with the dip tube. Moreover, the second tank and the dip tube are made in one piece from molded plastic. The breakable wall defines a zone of least resistance favoring breakage at this location. The second reservoir closes the first reservoir, and a plug seals the second reservoir by threaded pπse on the threaded neck of the first reservoir. The pump is then not in place on the distributor. The distributor is therefore sold with the pump separately. This requires special packaging. In addition, there is a risk of dirtying or damaging the pump when handling it.
Le premier réservoir contient un produit et le second réservoir contient un autre produit. On comprend aisément que les deux produits peuvent se mélanger après rupture de la paroi cassable.The first tank contains one product and the second tank contains another product. It is easily understood that the two products can mix after rupture of the breakable wall.
Lorsque l'utilisateur veut réaliser le mélange extemporané, il doit tout d'abord retirer le bouchon du col fileté du premier réservoir. Ainsi, le second réservoir est largement ouvert et il y a un πsque de renverser le produit contenu dans le second réservoir. De plus, il y a un πsque de déteπoration du produit au contact de l'air. Pour casser la paroi, l'utilisateur se sert de la pompe en introduisant l'extrémité inférieure de la pompe dans le tube plongeur encore fixée au second réservoir. La pression initiale a pour effet de solidariser la pompe à l'extrémité supérieure du tube plongeur. Une pression ultérieure plus forte a pour effet de faire casser la paroi et ainsi réaliser un passage de communication entre les deux réservoirs. Le produit stocké dans le second réservoir peut alors s'écouler dans le premier réservoir autour du tube plongeur qui est alors uniquement solidaire de la pompe, et plus du second réservoir.When the user wants to make the extemporaneous mixing, he must first remove the cap from the threaded neck of the first tank. Thus, the second tank is wide open and there is a risk of spilling the product contained in the second tank. In addition, there is a risk of deteπoration of the product in contact with air. To break the wall, the user uses the pump by inserting the lower end of the pump into the dip tube still attached to the second tank. The initial pressure has the effect of securing the pump to the upper end of the dip tube. A higher subsequent pressure has the effect of breaking the wall and thus providing a communication passage between the two tanks. The product stored in the second tank can then flow into the first tank around the dip tube which is then only integral with the pump, and no longer from the second tank.
Une opération finale consiste à monter une bague de fixation sur le col fileté du premier réservoir dans le but de fixer la pompe sur le second réservoir. Dans le distributeur du document, on se sert de la pompe pour faire céder la cloison qui sépare les deux réservoirs. Cependant, c'est la main de l'utilisateur qui agit directement sur la pompe en la poussant à l'intérieur du second réservoir.A final operation consists in mounting a fixing ring on the threaded neck of the first tank in order to fix the pump on the second tank. In the document dispenser, the pump is used to divide the partition that separates the two tanks. However, it is the user's hand which acts directly on the pump by pushing it inside the second tank.
Le risque de renverser le produit contenu dans le second réservoir ouvert est d'autant plus grand que la rupture de la paroi cassable engendre un à-coup qui fait bouger brusquement la pompe et les réservoirs.The risk of spilling the product contained in the second open tank is all the greater as the rupture of the breakable wall generates a jerk which makes the pump and the tanks suddenly move.
De plus, l'utilisateur peut endommager la pompe, le tube-plongeur ou encore un des réservoirs par une mauvaise manipulation, par exemple une poussée trop forte sur la pompe.In addition, the user can damage the pump, the dip tube or even one of the tanks by improper handling, for example a too strong push on the pump.
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un distributeur de mélange extemporané dont l'utilisation est simplifiée et sans risque de détérioration du distributeur et de perte ou d'altération de produit.The present invention aims to remedy the aforementioned drawbacks of the prior art by defining an extemporaneous mixture dispenser whose use is simplified and without risk of deterioration of the dispenser and loss or alteration of product.
Selon l'invention, il est prévu des moyens de déplacement pour déplacer l'organe de distribution vers la cloison pour la faire céder et ainsi permettre, avant distribution, le mélange des contenus des deux réservoirs. Avantageusement, l'organe de distribution s'étend à l'intérieur d'un des deux réservoirs, ledit réservoir comportant une paroi formant ladite cloison. L'organe de distribution est donc déjà en place dans un des deux réservoirs, mais pas dans sa position définitive qui ne sera atteinte que lorsque la cloison commune aura été enlevée ou sera détruite par l'organe de distribution lors de son déplacement. Selon une autre caractéristique, l'organe de distribution est fixé sur un des deux réservoirs par des moyens de fixation et déplaçable par rapport à ce réservoir entre une position initiale où la cloison sépare les deux réservoirs et une position finale où la cloison a cédé sous la pression de l'organe de distribution. De préférence, les deux réservoirs sont montés fixement l'un par rapport à l'autre. L'organe de distribution est ainsi déplaçable par rapport aux deux réservoirs qui forment une entité inséparable.According to the invention, there are provided displacement means for moving the dispensing member toward the partition to cause it to give way and thus allow, before dispensing, the mixing of the contents of the two tanks. Advantageously, the dispensing member extends inside one of the two reservoirs, said reservoir comprising a wall forming said partition. The dispensing member is therefore already in place in one of the two tanks, but not in its final position which will only be reached when the common partition has been removed or will be destroyed by the dispensing member during its movement. According to another characteristic, the dispensing member is fixed to one of the two tanks by fixing means and movable relative to this tank between an initial position where the partition separates the two tanks and a final position where the partition has failed under the pressure of the dispensing member. Preferably, the two tanks are fixedly mounted relative to each other. The distribution member is thus movable relative to the two reservoirs which form an inseparable entity.
Selon une caractéristique intéressante, les moyens de déplacement sont formés par lesdits moyens de fixation. Selon une autre caractéristiques intéressante, les réservoirs sont obturés hermétiquement en position initiale, en position finale et lors du déplacement de l'organe de distribution entre ces deux positions. Ainsi, l'utilisateur n'a qu'à agir sur les moyens de fixation pour déplacer l'organe de distribution sans risque de perdre du produit.According to an advantageous characteristic, the displacement means are formed by said fixing means. According to another advantageous characteristic, the reservoirs are hermetically sealed in the initial position, in the final position and during the movement of the dispensing member between these two positions. Thus, the user only has to act on the fixing means to move the dispensing member without risk of losing the product.
Selon une forme de réalisation, les deux positions initiale et finale sont des positions d'encliquetage. Avantageusement, les moyens de fixation comprennent une bague de fixation coopérant par encliquetage avec un des deux réservoirs entre ces deux positions. La technique d'encliquetage d'un organe de distribution à l'aide d'une bague sur un réservoir est une technique tout à fait classique, hormis que dans la présente invention, il est prévu deux positions d'encliquetage, à savoir une initiale et une finale. En variante, les deux positions initiale et finale sont des positions de vissage.According to one embodiment, the two initial and final positions are snap positions. Advantageously, the fixing means comprise a fixing ring cooperating by snap-fastening with one of the two reservoirs between these two positions. The technique of snap-fitting a dispensing member using a ring on a reservoir is a completely conventional technique, except that in the present invention, there are two snap-in positions, namely an initial and a finale. As a variant, the two initial and final positions are screwing positions.
Avantageusement, les moyens de fixation comprennent une bague de fixation coopérant par vissage avec un des deux réservoirs entre ces deux positions. Là encore, il s'agit d'une technique tout à fait conventionnelle et la position finale peut par exemple être atteinte en fin de vissage. Selon une autre caractéristique, un réservoir dit second réservoir obture de manière étanche l'autre réservoir dit premier réservoir. Avantageusement, l'organe de distribution obture de manière étanche le second réservoir formant la cloison.Advantageously, the fixing means comprise a fixing ring cooperating by screwing with one of the two tanks between these two positions. Again, this is a completely conventional technique and the final position can for example be reached at the end of screwing. According to another characteristic, a tank called the second tank seals the other tank said to be the first tank. Advantageously, the dispensing member sealingly seals the second reservoir forming the partition.
Afin de garantir une parfaite étanchéité lors du déplacement de l'organe de distribution, celui-ci comprend une lèvre d' étanchéité montée coulissante contre une paroi interne cylindrique du second réservoir. Ainsi, le distributeur est parfaitement étanche en position initiale ainsi qu'au cours du déplacement de l'organe de distribution.In order to guarantee perfect sealing during the displacement of the dispensing member, the latter comprises a sealing lip mounted slidingly against a cylindrical internal wall of the second reservoir. Thus, the dispenser is perfectly sealed in the initial position as well as during the movement of the dispensing member.
Selon une réalisation pratique, l'organe de distribution est encliqueté ou vissé sur le premier réservoir. D'autre part, le second réservoir est monté serrant à l'intérieur du premier réservoir. Selon une forme de réalisation préférée, l'organe de distribution comprend un tube plongeur qui s'étend dans un réservoir en direction de la cloison de manière à faire céder la cloison par déplacement de l'organe de distribution vers la cloison.According to a practical embodiment, the dispensing member is snapped on or screwed onto the first reservoir. On the other hand, the second tank is mounted squeezing inside the first tank. According to a preferred embodiment, the distribution member comprises a dip tube which extends in a reservoir in the direction of the partition so as to cause the partition to yield by displacement of the distribution member towards the partition.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non-limitatif deux modes de réalisation de la présente invention. Sur les dessins les figures la et lb sont des vues en coupe transversale verticale à travers un distributeur selon l'invention respectivement en position initiale et en position finale, et - les figures 2a et 2b sont des vues similaires a celles des figures la et lb pour un distnbuteur selon un second mode de réalisation de l'invention.The invention will now be described more fully with reference to the accompanying drawings which give two embodiments of the present invention by way of non-limiting example. In the drawings, FIGS. 1a and 1b are views in vertical cross section through a dispenser according to the invention in the initial position and in the final position respectively, and - FIGS. 2a and 2b are views similar to those of FIGS. for a distributor according to a second embodiment of the invention.
Le distπbuteur de mélange extemporané selon l' invention comprend trois éléments constitutifs essentiels, à savoir un premier réservoir 1, un second réservoir 2 et un organe de dιstnbutιon 3. Le premier réservoir 1 peut être réalisé en verre ou en matière plastique et comprend un corps 10 définissant un volume interne destmé a contenir un premier produit fluide PI. Le premier réservorr 1 forme à son extrémité supeneure un col 11 qui forme extéπeurement des profils d'encliquetage 111, 112 ou de vissage 110.The extemporaneous mixing distributor according to the invention comprises three essential constituent elements, namely a first tank 1, a second tank 2 and a setting member 3. The first tank 1 can be made of glass or plastic and comprises a body 10 defining an internal volume intended to contain a first fluid product PI. The first reservorr 1 forms at its upper end a neck 11 which forms the snap-fastening profiles 111, 112 or screwing profiles 110.
Le second réservorr 2, qui peut être réalisé en matière plastique, s'étend à l'inténeur du premier réservoir 1, de sorte qu'il est partiellement entouré par le produit fluide PI. Le second réservorr 2 comprend un corps 20 obturé à son extrémité inféneure par une cloison 21. A son extrémité supéπeure, le corps 20 du second réservoir 2 forme une collerette 22 qui s'étend radialement vers l'extéπeur. Le second réservoir 2 est engagé à l'mtéπeur du premier réservoir 1 avec un contact serrant du corps 20 du second réservoir 2 contre la paroi interne du col 11 du premier réservoir 1. La position définitive du second réservorr 2 a l'inténeur du premier réservoir 1 est atteinte lorsque la collerette radiale 22 vient en butée contre la surface supéπeure du col 11 du premier réservoir 1. Le contact serrant entre le corps 20 et le col 11 est parfaitement étanche de sorte que le second réservoir 2 obture hermétiquement le premier réservoir 1. Le second réservoir 2 contient un second produit fluide P2, séparé du premier produit fluide PI par la cloison commune 21.The second reserve 2, which can be made of plastic, extends inside the first tank 1, so that it is partially surrounded by the fluid PI. The second reservorr 2 comprises a body 20 closed at its lower end by a partition 21. At its upper end, the body 20 of the second tank 2 forms a flange 22 which extends radially towards the exterior. The second reservoir 2 is engaged in the metering of the first reservoir 1 with a tight contact of the body 20 of the second reservoir 2 against the internal wall of the neck 11 of the first reservoir 1. The final position of the second reservorr 2 has the interior of the first tank 1 is reached when the radial flange 22 abuts against the upper surface of the neck 11 of the first tank 1. The tight contact between the body 20 and the neck 11 is perfectly sealed so that the second tank 2 hermetically seals the first tank 1. The second reservoir 2 contains a second fluid product P2, separated from the first fluid product PI by the common partition 21.
Selon l'invennon, la cloison commune 21 peut être percée, déchirée ou séparée du corps 20 de manière à mettre les produits PI et P2 en contact pour réaliser un mélange de ces produits. La cloison 21 peut être complètement séparée du corps 20 mais peut également rester rattachée au corps par exemple par un pont de matière réalisant une forme de charnière. L'enlèvement partiel ou total de la cloison 21 est préféré a son percement ou son déchirement afin de réaliser un passage plus grand entre le réservoir 1 et le réservoir 2 pour favoπser et améliorer le mélange des produits PI et P2.According to the invention, the common partition 21 can be pierced, torn or separated from the body 20 so as to bring the products PI and P2 into contact to produce a mixture of these products. The partition 21 can be completely separated from the body 20 but can also remain attached to the body for example by a bridge of material providing a form of hinge. Partial or total removal of the partition 21 is preferred to piercing or tearing it in order to achieve a larger passage between the reservoir 1 and the reservoir 2 to favor and improve the mixing of the products PI and P2.
Selon l'invention, on se sert de l'organe de distπbution 3 pour faire céder la cloison commune 21. Pour ce faire, l'organe de distπbution 3 est déplaçable en direction de la cloison commune 21 entre une position initiale dans laquelle la cloison sépare les deux réservoirs 1 et 2, et une position finale dans laquelle la cloison a cédé sous la pression de l'organe de distribution. L'organe de distribution 3 peut donc se déplacer translativement en direction de la cloison 21 Avantageusement, l'organe de distribution 3 est pourvu d'un tube plongeur 32 dont l'extrémité sert d'organe de poussée ou de percement qui vient en contact avec la cloison 21 pour la faire céder. On peut également prévoir un organe de poussée sous la forme d'une tige ngide ou encore d'un tube qui s'étend à côté ou autour du tube plongeur.According to the invention, the distπbution member 3 is used to cause the common partition 21 to yield. To do this, the distπbution member 3 can be moved in the direction of the common partition 21 between an initial position in which the partition separates the two tanks 1 and 2, and a final position in which the partition has yielded under the pressure of the dispensing member. The distribution member 3 can therefore move translatively in the direction of the partition 21 Advantageously, the distribution member 3 is provided with a dip tube 32, the end of which serves as a pushing or piercing member which comes into contact with the partition 21 to make it yield. It is also possible to provide a thrust member in the form of a rigid rod or else of a tube which extends next to or around the dip tube.
L'organe de distribution, qui peut être une pompe, une valve, ou encore un bouchon, est fixé à un des deux réservoirs, en l'occurrence le premier réservoir 1, à l'aide de moyens de fixation, ici sous la forme d'une bague 33. La bague 33 qui peut faire partie intégrante ou non de l'organe de distπbution 3 coopère avec le col profilé 11 du premier réservoir 1, soit par encliquetage, comme représenté sur les figures la et lb, soit par vissage, comme représenté sur les figures 2a et 2b. Dans le premier mode de réalisation représenté sur les figures la et lb, le col 11 du premier réservorr 1 forme deux gorges d'encliquetage 111 et 112, alors que la bague forme un profil d'encliquetage 330. Dans la position initiale correspondant à la figure la, le profil d'encliquetage 330 de la bague 33 est engagé dans la première gorge d'encliquetage 111 du col 11. Par pression sur la bague 33, on peut amener le profil d'encliquetage 330 à sortir de la gorge 111 et à venir s'enc queter dans la seconde gorge d'enchquetage 112 du col 11. Au cours de ce déplacement, le tube plongeur 32 s'est déplace translativement vers la cloison 21 de manière à la faire céder, comme représenté sur la figure lb.The dispensing member, which can be a pump, a valve, or even a plug, is fixed to one of the two tanks, in this case the first tank 1, using fixing means, here in the form of a ring 33. The ring 33 which may or may not form an integral part of the distribution member 3 cooperates with the profiled neck 11 of the first reservoir 1, either by snap-fastening, as shown in FIGS. 1 a and 1 b, or by screwing , as shown in Figures 2a and 2b. In the first embodiment shown in Figures la and lb, the neck 11 of the first reservorr 1 forms two snap grooves 111 and 112, while the ring forms a snap profile 330. In the initial position corresponding to the FIG. 1a, the latching profile 330 of the ring 33 is engaged in the first latching groove 111 of the neck 11. By pressing on the ring 33, it is possible to cause the latching profile 330 to come out of the groove 111 and coming to be polled in the second groove 112 in the neck 11. During this movement, the dip tube 32 moves translatively towards the partition 21 so as to cause it to yield, as shown in FIG. 1b .
Dans la vanante représentée sur les figures 2a et 2b, le principe est le même avec une fixation par vissage Pour ce faire, le col 11 du premier réservoir 1 est formé avec un filetage extéπeur 110 alors que la bague 33 forme un filetage interne 333 en prise avec le col fileté 11. Dans la position représentée sur la figure 2a, la bague 33 n'est pas vissée à fond sur le col 11 et l'extrémité du tube plongeur reste en éloignement ou juste en contact de la cloison 21 sans la faire céder. En vissant la bague 33 sur le col 11, le tube plongeur 32 se déplace translativement vers la cloison 21 jusqu'à la faire céder, ce qui coπespond à la position représentée sur la figure 2b. La position finale peut par exemple être atteinte lorsque la bague 33 est vissée a fond sur le col fileté 11In the valve shown in FIGS. 2a and 2b, the principle is the same with a screw fixing. To do this, the neck 11 of the first tank 1 is formed with an external thread 110 while the ring 33 forms an internal thread 333 in taken with the threaded neck 11. In the position shown in FIG. 2a, the ring 33 is not fully screwed onto the neck 11 and the end of the dip tube remains remote or just in contact with the partition 21 without the give up. By screwing the ring 33 on the neck 11, the dip tube 32 moves translatively towards the partition 21 until it yields, which corresponds to the position shown in FIG. 2b. The final position can for example be reached when the ring 33 is screwed fully onto the threaded neck 11
On a déjà vu que l'étanchéité entre les deux réservoirs 1 et 2 est réalisée par le contact serrant du corps 20 contre la paroi interne du col 11. Afin de garantir une parfaite étanchéité entre l'organe de distribution 3 et les réservoirs, la bague de fixation 33 forme également une lèvre d'étanchéité sous la forme d'une jupe 331 qui vient en contact étanche de coulissement contre une partie cylindπque de la paroi interne du corps 20 du second réservoir 2. L'étanchéité du distributeur est ainsi garantie en position initiale, en position finale mais également lors du déplacement du corps de pompe pour atteindre la position finale. On évite ainsi tout risque de perte de produit lors du mélange des produits.We have already seen that the seal between the two reservoirs 1 and 2 is achieved by the tightening contact of the body 20 against the internal wall of the neck 11. In order to guarantee a perfect seal between the dispensing member 3 and the reservoirs, the fixing ring 33 form also a sealing lip in the form of a skirt 331 which comes into leaktight sliding contact against a cylindrical part of the internal wall of the body 20 of the second tank 2. The sealing of the dispenser is thus guaranteed in the initial position, in final position but also when moving the pump body to reach the final position. This avoids any risk of product loss when mixing the products.
Une caractéπstique de l'invention est de maintenir l'étanchéité du distributeur lors de l'opération de mélange, et ceci peut se faire avec des moyens de déplacement propres au distπbuteur, par exemple en se servant des moyens de fixation pour déplacer l'organe de distribution afin de casser la cloison de séparation des deux réservoirs. Dans les exemples ci-dessus, c'est la bague de fixation qui se déplace avec l'organe de distπbution sur le col d'un des réservoir. On peut également imaginer que la bague puisse permettre le déplacement seul de l'organe de distribution dans la bague qui reste fixe sur le réservoir. Dans ce cas aussi, les moyens de fixation forment des moyens de déplacement pour l'organe de distribution. Grâce à l'invention, l'utilisateur peut effectuer le mélange des deux produits PI et P2 au dernier moment juste avant d'acnonner le distπbuteur, simplement en agissant sur la bague 33 soit par poussée dans le cas de l' encliquetage, soit par rotation dans le cas du vissage. A characteristic of the invention is to maintain the tightness of the dispenser during the mixing operation, and this can be done with displacement means specific to the distributor, for example by using fixing means to move the member. distribution in order to break the partition separating the two tanks. In the examples above, it is the fixing ring which moves with the dispensing member on the neck of one of the tanks. One can also imagine that the ring could allow the displacement alone of the dispensing member in the ring which remains fixed on the tank. In this case also, the fixing means form displacement means for the dispensing member. Thanks to the invention, the user can perform the mixing of the two products PI and P2 at the last moment just before acknowledging the distributor, simply by acting on the ring 33 either by pushing in the case of snap-fastening, or by rotation in the case of screwing.
