Description

DISPOSITIF DE CONDITIONNEMENT ET DE DISTRIBUTION DE PLUSIEURS FLUIDES COMPORTANT AU MOINS DEUX POMPES. DEVICE FOR PACKAGING AND DISPENSING MULTIPLE FLUIDS COMPRISING AT LEAST TWO PUMPS.
La présente invention concerne un nouveau dispositif de conditionnement et de distribution de produits fluides, et plus particulièrement un dispositif de conditionnement et de distribution de produits fluides, liquides ou pâteux, du type comportant au moins deux pompes et deux réservoirs, par exemple deux poches souples placées dans un même récipient rigide, assurant le stockage d'au moins deux produits fluides à l'abri de l'air et leur distribution simultanée.The present invention relates to a new device for packaging and dispensing fluid products, and more particularly to a device for packaging and dispensing fluid, liquid or pasty products, of the type comprising at least two pumps and two reservoirs, for example two flexible bags. placed in the same rigid container, ensuring the storage of at least two fluid products protected from air and their simultaneous distribution.
Divers types de distributeurs à plusieurs compartiments sont bien connus. De tels distributeurs permettent de conserver plusieurs produits séparément, pour éviter par exemple qu'ils ne réagissent entre eux, afin de ne les mélanger qu'au moment de leur utilisation. Ainsi, la demande WO 99.64319 décrit un dispositif simple adapté à la distri- bution simultanée de deux fluides au moyen d'une double pompe, plus particulièrement destiné à des pâtes ou gels dentifrices. Ce dispositif comprend une partie haute montée télescopi- quement sur une partie basse, constituant une pompe à deux pistons se déplaçant parallèlement dans deux cylindres solidaires de la partie basse. Chaque pression sur la partie haute formant poussoir provoque l'expulsion de quantités variables de produits. Un tel dispositif ne peut donc pas convenir lorsqu'il est nécessaire de distribuer des quantités prédéterminées et constantes de produits. La demande WO 95.30490 décrit un dispositif de distribution à deux chambres, destiné à la vaporisation d'un produit relativement visqueux, au moyen d'un gaz comprimé. Le système, du type à tiroir, fonctionne grâce à une tige portant deux pistons, se déplaçant simultanément et parallèlement, l'un dans une première chambre contenant le produit visqueux provenant du récipient, l'autre dans une deuxième chambre contenant le gaz de vaporisation, en général de l'air prove- nant de l'extérieur. Suivant une variante du même dispositif, le gaz peut être remplacé par un deuxième composant, et dans ce cas la deuxième chambre communique avec le récipient qui contient les deux produits, dont l'un est dans une poche souple. Le brevet US 5.918.771 décrit un dispositif de ι pulvérisation par aérosol, pouvant comporter deux récipients dont chacun communique avec une pompe, les deux pompes étant concentriques et actionnées simultanément par un même poussoir. Les dispositifs du type flacon-poche pour assurer le conditionnement et la distribution de fluides sont bien connus, et comportent généralement un récipient à coque rigide dans lequel est placée une poche souple qui se rétracte au fur et à mesure que le produit en est extrait. L'expulsion du produit hors de la poche peut être obtenue au moyen d'une pompe "airless", ou sans reprise d'air, et dans ce cas un évent est prévu, généralement dans le fond ou dans le col du flacon, pour permettre à l'air extérieur de pénétrer dans 1 ' espace situé entre le flacon et la poche à chaque actionnement de la pompe et permettre ainsi à la poche de se rétracter en maintenant une pression suffisante sur ses parois. Grâce à la présence d'une pompe, les dispositifs de ce types permettent de distribuer des doses sensiblement constantes de produit . Le brevet FR 2.723.356 décrit un exemple de dispositif suivant cette technique, comportant une poche en matière plastique souple placée dans un récipient rigide dont le col comporte une entrée d'air. Le brevet FR 2.804.666 décrit un autre dispositif utilisant cette technique, adapté à la distribution sélective d'un ou deux produits, isolément ou en mélange, suivant lequel un premier produit est introduit dans la poche tandis que le deuxième, ainsi que le gaz propulseur, se trouvent dans le récipient rigide, autour de la poche, l'ensemble étant complété par une valve sélective. Cependant, ce système est relativement complexe et requiert une valve spéciale.Various types of multi-compartment dispensers are well known. Such dispensers make it possible to keep several products separately, to prevent for example that they do not react with each other, so as to mix them only at the time of their use. Thus, application WO 99.64319 describes a simple device suitable for the simultaneous distribution of two fluids by means of a double pump, more particularly intended for toothpaste pastes or gels. This device comprises an upper part mounted telescopically on a lower part, constituting a pump with two pistons moving in parallel in two cylinders integral with the lower part. Each press on the upper part forming a pusher causes the expulsion of variable quantities of products. Such a device cannot therefore be suitable when it is necessary to dispense predetermined and constant quantities of products. Application WO 95.30490 describes a two-chamber distribution device, intended for the vaporization of a relatively viscous product, by means of a compressed gas. The system, of the drawer type, works thanks to a rod carrying two pistons, moving simultaneously and parallel, one in a first chamber containing the viscous product coming from the container, the other in a second chamber containing the vaporizing gas. , usually air from from outside. According to a variant of the same device, the gas can be replaced by a second component, and in this case the second chamber communicates with the container which contains the two products, one of which is in a flexible pocket. US Patent 5,918,771 describes a device for aerosol spraying, which may include two containers, each of which communicates with a pump, the two pumps being concentric and actuated simultaneously by the same pusher. The devices of the bottle-pocket type for ensuring the packaging and distribution of fluids are well known, and generally comprise a container with a rigid shell in which is placed a flexible pocket which shrinks as the product is extracted therefrom. The expulsion of the product from the bag can be obtained by means of an "airless" pump, or without air intake, and in this case a vent is provided, generally at the bottom or in the neck of the bottle, to allow outside air to enter the space between the bottle and the bag each time the pump is actuated and thus allow the bag to retract while maintaining sufficient pressure on its walls. Thanks to the presence of a pump, devices of this type make it possible to dispense substantially constant doses of product. Patent FR 2,723,356 describes an example of a device according to this technique, comprising a flexible plastic bag placed in a rigid container whose neck has an air inlet. Patent FR 2,804,666 describes another device using this technique, suitable for the selective distribution of one or two products, individually or as a mixture, according to which a first product is introduced into the bag while the second, as well as the gas propellant, are in the rigid container, around the pocket, the assembly being completed by a selective valve. However, this system is relatively complex and requires a special valve.
Une difficulté inhérente à ces. dispositifs du type flacon-poche est d'assurer une étanchéité satisfaisante de la poche permettant de préserver 1 ' intégrité du produit qui y est contenu. En effet, les produits que contiennent les poches sont souvent sensibles à l'oxydation provoquée par l'oxygène de l'air et peuvent se dégrader si de l'air s'introduit dans la poche. Les défauts d' étanchéité se rencontrent souvent au niveau de la jonction de la poche et de la pompe. Ils peuvent aussi résulter d'une certaine porosité des matériaux utilisés pour la réalisation de la poche, ou de déchirures dans les plis formés par la paroi de la poche au cours de sa rétractation, ce qui a pour effet de laisser passer de l'air qui atteint alors le produit contenu dans la poche.An inherent difficulty with these. devices of the bottle-pocket type is to ensure a satisfactory seal of the pocket to preserve one integrity of the product contained therein. Indeed, the products contained in the bags are often sensitive to oxidation caused by the oxygen in the air and can deteriorate if air is introduced into the bag. Sealing faults are often encountered at the junction of the bag and the pump. They can also result from a certain porosity of the materials used for the production of the pocket, or from tears in the folds formed by the wall of the pocket during its retraction, which has the effect of allowing air to pass through. which then reaches the product contained in the pocket.
Ces difficultés se trouvent encore accrues lorsque l'on souhaite utiliser deux ou plusieurs poches incluses dans un même récipient rigide afin d'assurer la distribution, simultanée ou non, de deux ou plusieurs produits complémentaires l'un de l'autre. Une autre difficulté inhérente aux dispositifs comportant deux poches et deux pompes résulte de leur encombrement .These difficulties are further increased when it is desired to use two or more bags included in the same rigid container in order to ensure the distribution, simultaneously or not, of two or more products complementary to one another. Another difficulty inherent in devices comprising two pockets and two pumps results from their bulk.
La présente invention a précisément pour objet un dispositif de conditionnement et de distribution de produits fluides, liquides ou pâteux, du type comportant au moins deux pompes d'extraction à axes parallèles et au moins deux réservoirs contenant les produits à distribuer, capable de délivrer des doses prédéterminées et constantes de produits, et occupant un volume aussi compact que possible. L'invention a aussi pour objet un dispositif du type flacon - poche comprenant au moins deux poches souples étanches placées dans un même récipient rigide unique, associées à au moins deux pompes, assurant une distribution efficace d'au moins deux produits simultanément ou séquen- tiellement, séparément ou en mélange. L'invention a aussi pour objet un dispositif de conditionnement et de distribution de plusieurs produits fluides contenus chacun dans une poche séparée, assurant une très bonne facilité de remplissage des poches sans qu'il soit nécessaire de recourir à un outillage complexe ou spécialement adapté .The present invention specifically relates to a device for packaging and dispensing fluid, liquid or pasty products, of the type comprising at least two extraction pumps with parallel axes and at least two tanks containing the products to be dispensed, capable of delivering predetermined and constant doses of products, occupying as compact a volume as possible. The subject of the invention is also a device of the bottle-pocket type comprising at least two watertight flexible bags placed in the same single rigid container, associated with at least two pumps, ensuring efficient distribution of at least two products simultaneously or sequentially. partially, separately or as a mixture. The invention also relates to a device for packaging and dispensing several fluid products each contained in a separate bag, ensuring very good ease of filling the bags without the need for complex or specially adapted tools.
L'invention a encore pour objet un dispositif de conditionnement et de distribution de plusieurs produits fluides, du type comportant au moins deux poches souples étanches placées dans un même récipient rigide unique, assurant un parfait conditionnement des produits au moyen d'une excellente étanchéité de la poche.The invention also relates to a device for packaging and distributing several fluid products, of the type comprising at least two waterproof flexible bags placed in the same single rigid container, ensuring perfect packaging of the products by means of an excellent seal of the pocket.
L'invention a enfin pour objet un dispositif du type indiqué ci-dessus, qui peut être fabriqué dans de bonnes conditions de rentabilité.The invention finally relates to a device of the type indicated above, which can be manufactured under good conditions of profitability.
Le dispositif de conditionnement et de distribution de produits fluides suivant la présente invention est du type comportant au moins deux pompes à axes parallèles et au moins deux réservoirs, chaque réservoir communiquant avec une pompe, et il se distingue en ce que la première pompe est montée mobile axialement dans la chambre de la deuxième pompe, de telle sorte que le mouvement de la première pompe entraîne le fonctionnement de la deuxième pompe.The device for packaging and distributing fluid products according to the present invention is of the type comprising at least two pumps with parallel axes and at least two reservoirs, each reservoir communicating with a pump, and it is distinguished in that the first pump is mounted axially movable in the chamber of the second pump, so that the movement of the first pump causes the operation of the second pump.
Suivant une forme préférentielle de réalisation, le dispositif de l'invention comporte un poussoir unique agissant sur le piston de la première pompe et il comprend des moyens pour que le mouvement du poussoir entraîne le déplacement du corps de la première pompe et du piston de la deuxième pompe dans la chambre de la deuxième pompe . Suivant une forme de réalisation le poussoir est conçu pour que ce déplacement se fasse lorsque le piston de la première pompe est en fin de course. Ainsi, les pistons des pompes ne sont pas montés sur une même tige et peuvent se déplacer suivant des mouvements indépendants avec des courses qui peuvent être identiques ou différentes. Comme indiqué ci-dessus, les deux pompes sont actionnées par un même poussoir et sont mobiles suivant des axes parallèles, et de préférence les deux pompes sont coaxiales.According to a preferred embodiment, the device of the invention comprises a single pusher acting on the piston of the first pump and it comprises means so that the movement of the pusher causes the body of the first pump and the piston of the second pump in the chamber of the second pump. According to one embodiment, the pusher is designed so that this movement takes place when the piston of the first pump is at the end of its travel. Thus, the pistons of the pumps are not mounted on the same rod and can move in independent movements with strokes which may be the same or different. As indicated above, the two pumps are actuated by the same pusher and are movable along parallel axes, and preferably the two pumps are coaxial.
Chaque pompe du dispositif de l'invention comporte un tube plongeur communiquant avec des réservoirs indépendants, constitués de préférence par des poches souples étanches placées dans un même récipient rigide unique, et comprenant des moyens coopérant avec au moins une bague de fixation au récipient rigide et avec les pompes. Le dispositif conforme à la présente invention comprend des moyens pour coordonner le mouvement des deux pompes . Dans une forme de réalisation, ces moyens provoquent l'expulsion séquentielle des produits contenus dans les réservoirs ou les poches, et ils sont constitués par des butées coopérant avec des epaulements formés sur le poussoir d'une part, et sur des pièces solidaires des pompes d'autre part, ou inversement, de telle sorte qu'au cours du mouvement du poussoir, un épaulement viennent prendre appui contre une butée, entraînant alors la pièce correspondante. Ainsi, en plaçant judicieu- sèment les butées et les epaulements, on peut faire en sorte que le mouvement du poussoir, à partir de la position de repos, provoque successivement le déplacement de la tige du piston de la première pompe et l'ouverture du clapet supérieur, puis l'enfoncement du piston de la première pompe dans sa chambre, entraînant l'expulsion du produit qui y était contenu, l'ouverture du clapet supérieur de la deuxième pompe, et enfin le déplacement de la première pompe, formant piston, dans la chambre de la deuxième pompe, entraînant l'expulsion du produit contenu dans cette deuxième chambre . Dans cette forme de réalisation, les produits contenus dans chaque pompe sont expulsés immédiatement l'un après l'autre au cours du même déplacement du poussoir.Each pump of the device of the invention comprises a dip tube communicating with independent reservoirs, preferably constituted by watertight flexible bags placed in the same single rigid container, and comprising means cooperating with at least one ring for fixing to the rigid container and with the pumps. The device according to the present invention comprises means for coordinating the movement of the two pumps. In one embodiment, these means cause the sequential expulsion of the products contained in the tanks or the pockets, and they consist of stops cooperating with shoulders formed on the pusher on the one hand, and on parts integral with the pumps. on the other hand, or vice versa, so that during the movement of the pusher, a shoulder come to bear against a stop, then driving the corresponding part. Thus, by judiciously placing the stops and the shoulders, it is possible to ensure that the movement of the pusher, from the rest position, successively causes the displacement of the piston rod of the first pump and the opening of the upper valve, then pushing the piston of the first pump into its chamber, causing the expulsion of the product contained therein, opening the upper valve of the second pump, and finally the displacement of the first pump, forming the piston , in the chamber of the second pump, causing the expulsion of the product contained in this second chamber. In this embodiment, the products contained in each pump are expelled immediately one after the other during the same movement of the pusher.
Suivant une forme préférentielle de réalisation, le dispositif de l'invention comprend au moins deux poches combinées à une bague unique de fixation au récipient et aux pompes, la bague étant fixée aux poches par tout moyen connu de fixation tel que soudage, collage, encliquetage ou sertissage mécanique. La bague unique utilisée dans l'invention est avantageusement conçue pour permettre une fixation des poches par encliquetage de leur col sur la bague, ce qui assure une plus grande facilité de fabrication et d'assemblage des éléments du dispositif.According to a preferred embodiment, the device of the invention comprises at least two pockets combined with a single ring for fixing to the container and to the pumps, the ring being fixed to the pockets by any known means of fixing such as welding, gluing, snap-fastening or mechanical crimping. The single ring used in the invention is advantageously designed to allow the pockets to be fixed by snapping their neck onto the ring, which ensures greater ease of manufacture and assembly of the elements of the device.
Suivant une forme avantageuse de réalisation, les deux poches sont combinées à une bague unique de fixation au récipient et aux pompes, et peuvent être formées dans une seule pièce, sous la forme d'une poche double comportant deux compartiments séparés par une cloison. Une telle forme de réalisation à poche double présente l'avantage de rigidifier la structure de la poche au moyen de la cloison de séparation, ce qui a pour effet de faciliter la restitution des produits contenus dans les poches. La fixation des poches est assurée par tout moyen connu, par exemple par encliquetage de leur col sur la bague .According to an advantageous embodiment, the two pockets are combined with a single ring for fixing to the container and to the pumps, and can be formed in a single piece, in the form of a double pocket comprising two compartments separated by a partition. Such an embodiment with a double pocket has the advantage of stiffening the structure of the pocket by means of the partition, which has the effect of facilitating the return of the products contained in the pockets. The pockets are fixed by any known means, for example by snapping their neck onto the ring.
Suivant une variante conforme à l'invention, le dispo- sitif comprend deux poches insérées l'une dans l'autre, le col de la plus grande poche entourant celui de la plus petite, un espace suffisant étant ménagé entre les deux cols pour le remplissage et l'expulsion du produit.According to a variant according to the invention, the device comprises two pockets inserted one inside the other, the neck of the largest pocket surrounding that of the smallest, sufficient space being provided between the two necks for the filling and expulsion of the product.
Bien entendu, les deux poches peuvent être réalisées en un matériau différent, choisi en fonction des conditions d'utilisation ou de la nature des produits qu'elles contiennent. Par exemple, il peut être avantageux de choisir pour chaque poche un matériau adapté à la nature des produits utilisés, en particulier lorsque ces produits ont des propri- étés physico-chimiques impliquant l'utilisation de matériaux spécialement adaptés .Of course, the two pockets can be made of a different material, chosen according to the conditions of use or the nature of the products they contain. For example, it may be advantageous to choose for each bag a material suitable for the nature of the products used, in particular when these products have physicochemical properties implying the use of specially adapted materials.
Le dispositif conforme à la présente invention présente l'avantage d'être bien moins encombrant qu'un système associant deux pompes montées chacune sur une poche ou un réservoir et fonctionnant en parallèle, actionnées par un même poussoir ou par des poussoirs séparés. La compacité du dispositif de 1 ' invention résulte de 1 ' imbrication des pompes l'une dans l'autre et de leur complémentarité.The device according to the present invention has the advantage of being much less bulky than a system associating two pumps each mounted on a pocket or a tank and operating in parallel, actuated by the same push-button or by separate push-buttons. The compactness of the device of the invention results from the nesting of the pumps in one another and from their complementarity.
Les matières plastiques utilisées pour la fabrication des poches peuvent être choisies par exemple parmi un poly- éthylène, un polypropylène, un polyamide, un copolymère d'éthylène et d'alcool vinylique (EVOH) , etc. Il peut s'agir de matières monocouches ou de complexes multicouches incluant une couche métallique, par exemple une couche d'aluminium formant barrière renforçant 1 'étanchéité, combinée à une ou plusieurs couches de matière plastique. La fabrication de la poche à partir de ces matières peut être effectuée par des techniques telles que l'injection soufflage ou l'extrusion soufflage dans un moule adapté. On peut également fabriquer la poche par soudage d'un film plastique ou métallique, ou d'un complexe multicouche métal / plastique sur un support formant le col de la poche.The plastics used for the manufacture of the bags can be chosen, for example, from polyethylene, polypropylene, polyamide, a copolymer of ethylene and vinyl alcohol (EVOH), etc. They may be monolayer materials or multilayer complexes including a metal layer, for example an aluminum layer forming a barrier reinforcing the seal, combined with one or more layers of plastic. The manufacture of the bag from these materials can be carried out by techniques such as blow molding or blow molding in a suitable mold. The bag can also be manufactured by welding a plastic or metallic film, or a metal / plastic multilayer complex on a support forming the neck of the bag.
La matière utilisée pour la bague peut être une matière plastique de même nature que celle utilisé pour la poche, mais traitée de manière à lui conférer une rigidité suffisante, par exemple en utilisant une plus grande épaisseur de matière. On peut ainsi utiliser des bagues en polyéthylène ou en polypropylène, et comme indiqué ci-dessus, la bague et les poches peuvent être fabriquées en une seule pièce, par injection soufflage ou toute autre technique appropriée. Le récipient rigide peut être fabriqué en matière plastique ou en tout matériau rigide approprié. On peut par exemple fabriquer des récipients rigides en polyéthylène, en téréphtalate de polyéthylène (PET), en verre ou en métal tel que l'aluminium. Les ouvertures pratiquées dans la bague sont de préférence disposées symétriquement par rapport au centre de la bague, mais elle peuvent être déportées, selon la forme du cylindre et les effets recherchés.The material used for the ring may be a plastic material of the same nature as that used for the pocket, but treated so as to give it sufficient rigidity, for example by using a greater thickness of material. Polyethylene or polypropylene rings can thus be used, and as indicated above, the ring and the pockets can be manufactured in one piece, by injection blowing or any other suitable technique. The rigid container may be made of plastic or any suitable rigid material. One can for example make rigid containers of polyethylene, polyethylene terephthalate (PET), glass or metal such as aluminum. The openings made in the ring are preferably arranged symmetrically with respect to the center of the ring, but they can be offset, depending on the shape of the cylinder and the desired effects.
Le cylindre formé par la ou les poches peut avoir une forme quelconque. Par exemple, il peut ne pas former un corps de révolution, sa section n'étant pas circulaire, mais il est de préférence un cylindre droit à section hémi-circulaire comportant au moins une surface latérale plane servant à la jonction des poches entre elles dans le même récipient. D'autres formes peuvent être réalisées sans difficulté, et par exemple une forme sensiblement elliptique, ou une forme quelconque continue ou polygonale, ou encore une forme non cylindrique, selon l'effet esthétique recherché ou imposé par la forme du récipient rigide. Suivant 1 ' invention, on peut associer deux ou plusieurs poches identiques, mais il est également possible de combiner des poches de volumes différents, la chambre de dosage de chaque pompe étant alors de préférence adaptée au volume de la poche correspondante. Ceci est particulièrement avantageux dans le cas de la distribution de produits fluides complémentaires qui doivent être mélangés en quantités déterminées. Ainsi, un dispositif à récipient rigide et deux poches souples, chacune communiquant avec une pompe, suivant l'invention peut être adapté au rapport de mélange des deux produits contenus dans les poches, et si ce rapport doit être par exemple de 2/1, on peut prévoir que le volume de la deuxième poche est égal à la moitié de celui de la première, et de même pour le volume de la chambre de dosage de la deuxième pompe par rapport à la première. Ainsi, à chaque pression sur le poussoir unique, on expulse deux volumes du premier produit pour un seul du deuxième et les deux poches se vident parallèlement.The cylinder formed by the pocket or pockets can have any shape. For example, it may not form a body of revolution, its cross-section not being circular, but it is preferably a straight cylinder with semi-circular cross-section comprising at least one flat lateral surface serving to join the pockets together in the same container. Other shapes can be produced without difficulty, for example a substantially elliptical shape, or any continuous or polygonal shape, or even a non-cylindrical shape, depending on the desired aesthetic effect or imposed by the shape of the rigid container. According to the invention, it is possible to associate two or more identical bags, but it is also possible to combine bags of different volumes, the metering chamber of each pump then preferably being adapted to the volume of the corresponding bag. This is particularly advantageous in the case of the distribution of complementary fluid products which must be mixed in predetermined quantities. Thus, a device with a rigid container and two flexible pockets, each communicating with a pump, according to the invention can be adapted to the mixing ratio of the two products contained in the pockets, and if this ratio must be for example 2/1, one can provide that the volume of the second bag is equal to half that of the first, and the same for the volume of the metering chamber of the second pump relative to the first. Thus, each time the single pusher is pressed, two volumes of the first product are expelled for one of the second and the two pockets are emptied in parallel.
L'un des avantages du dispositif de l'invention associant chaque pompe à une poche séparée, est de permettre toutes les combinaisons de dosage de pompes et de remplissage des poches se trouvant dans le récipient rigide. En particulier, on peut jouer sur la longueur de la course du piston de chaque pompe pour ajuster le rapport des volumes des pompes.One of the advantages of the device of the invention associating each pump with a separate bag is that it allows all combinations of pump dosing and filling of the bags located in the rigid container. In particular, one can play on the length of the stroke of the piston of each pump to adjust the ratio of the volumes of the pumps.
Dans le cas d'un dispositif du type flacon-poche, pour que les poches puissent se rétracter à l'intérieur du récipient rigide, une arrivée d'air extérieur est prévue sous forme d'un évent ou d'un circuit d'aspiration d'air.In the case of a bottle-pocket type device, so that the bags can retract inside the rigid container, an external air supply is provided in the form of a vent or an air suction circuit.
Dans sa forme la plus simple, l' évent est prévu dans la paroi, par exemple dans le fond du récipient rigide, et il est de préférence muni d'un clapet et/ou d'un filtre. Le circuit d'air, permettant à l'air extérieur d'entrer dans le volume entre la paroi du récipient rigide et les poches, est de préférence conçu de manière à rester fermé tant que le fluide est conservé dans chaque poche et à ne s ' ouvrir qu' à chaque actionnement des pompes de manière à ne laisser entrer qu'un volume d'air équivalent au volume de fluide expulsé de chaque poche. En fin d' actionnement des pompes, le circuit d'air se trouve automatiquement fermé, ce qui assure une préservation optimale des produits contenus dans les poches en limitant 1 'évaporation à travers la paroi des poches.In its simplest form, the vent is provided in the wall, for example in the bottom of the rigid container, and it is preferably provided with a valve and / or a filter. The air circuit, allowing the outside air to enter the volume between the wall of the rigid container and the bags, is preferably designed so as to remain closed as long as the fluid is kept in each bag and not to s 'open only' on each actuation of the pumps so as to let in only an air volume equivalent to the volume of fluid expelled from each pocket. At the end of actuation of the pumps, the air circuit is automatically closed, which ensures optimal preservation of the products contained in the pockets by limiting evaporation through the wall of the pockets.
Suivant une forme préférentielle de réalisation, le circuit d'air est constitué par un passage aménagé dans le bord de la bague de fixation des pompes, communiquant avec l'espace entre les pompes et le poussoir, et comportant des moyens d'obturation, par exemple des clapets, tant que la pompe n'est pas actionnée. Ainsi, l'obturation du circuit d'air, en position de repos, peut être assurée par l' étanchéité réalisée entre les pompes et la bague de fixation.According to a preferred embodiment, the air circuit is constituted by a passage arranged in the edge of the pump fixing ring, communicating with the space between the pumps and the pusher, and comprising closure means, by example of valves, as long as the pump is not activated. Thus, the obturation of the air circuit, in the rest position, can be ensured by the seal produced between the pumps and the fixing ring.
Les produits fluides contenus dans les poches peuvent être expulsés pratiquement simultanément, c'est-à-dire au cours de la même course du poussoir. L'expulsion simultanée et contrôlée des produits fluides est avantageuse dans le cas de produits qui doivent être mélangés de manière extemporanée et en proportions déterminées. La présence d'un poussoir unique agissant sur deux ou plusieurs pompes facilite cette expulsion simultanée, et le choix de pompes comportant des chambres de dosage adaptées assure la composition du mélange suivant les proportions adéquates. Ainsi, les chambres de dosage des pompes peuvent être proportionnelles au volume des poches. De plus, le dispositif de l'invention peut comporter des buses de sortie de produit juxtaposées ou concentriques, pour assurer un excellent mélange des produits provenant de chaque poche. Suivant une variante, les conduits de sortie des pompes peuvent être réunis pour déboucher dans une buse de sortie commune. Le dispositif de l'invention peut plus particulièrement comporter une buse de sortie comprenant deux orifices annulaires concentriques masqués par une même lamelle élastique capable de se déformer pour laisser passer les fluides sortant des pompes, et de se plaquer à nouveau sur les orifices dès que la pression retombe.The fluid products contained in the pockets can be expelled practically simultaneously, that is to say during the same stroke of the pusher. The simultaneous and controlled expulsion of fluid products is advantageous in the case of products which must be mixed extemporaneously and in predetermined proportions. The presence of a single pusher acting on two or more pumps facilitates this simultaneous expulsion, and the choice of pumps having suitable metering chambers ensures the composition of the mixture in the appropriate proportions. Thus, the metering chambers of the pumps can be proportional to the volume of the bags. In addition, the device of the invention may include juxtaposed or concentric product outlet nozzles, to ensure an excellent mixing of the products coming from each bag. According to a variant, the outlet pipes of the pumps can be brought together to open into a common outlet nozzle. The device of the invention may more particularly comprise an outlet nozzle comprising two concentric annular orifices masked by the same elastic lamella capable of deforming to allow the fluids leaving the pumps to pass, and of being pressed again on the orifices as soon as the pressure drops.
Le dispositif suivant la présente invention présente l'avantage de pouvoir être facilement rempli sans qu'il soit nécessaire de disposer d'un outillage complexe. Conformément à la présente invention, le remplissage peut s'effectuer avec un outillage standard, par simple gravité, ce qui assure une très bonne régularité de remplissage. De plus, la grande liberté de forme de la poche permet de l'adapter aisément à des récipients rigides de formes variées. Diverses mentions et dessins peuvent être apposés sur les poches ou sur le récipient rigide, par exemple par impression ou sérigraphie, suivant l'utilisation envisagée.The device according to the present invention has the advantage of being able to be easily filled without the need for complex tools. In accordance with the present invention, filling can be carried out with standard tools, by simple gravity, which ensures very good filling regularity. In addition, the great freedom of shape of the pocket makes it easy to adapt it to rigid containers of various shapes. Various indications and drawings can be affixed on the pockets or on the rigid container, for example by printing or screen printing, depending on the intended use.
Lors de son utilisation et de l'extraction des produits qui y sont contenus, chaque poche se rétracte régulièrement en limitant les risques de fissuration ou de déchirure.During its use and the extraction of the products contained therein, each pocket regularly retracts, limiting the risk of cracking or tearing.
Le taux de restitution du produit, c'est-à-dire le rapport entre le volume de produit introduit dans la poche lors du remplissage et le volume extrait au cours de l'utilisation, est excellent, et peut être supérieur à 90 %. Le dispositif de conditionnement et de distribution de produits fluides suivant l'invention est tout particulièrement adapté au conditionnement et à la distribution de produits complémentaires susceptibles de réagir l'un sur l'autre, qui doivent être conservés séparément, et ne doivent être mélangés que lors de leur utilisation. Un domaine d'application est celui des compositions cosmétiques ou dermatologiques, telles que crèmes et gels, pouvant comprendre des composants ayant des propriétés très différentes, par exemple des phases aqueuses et des phases huileuses peu stables, et où il peut aussi être utile de procéder au mélange extemporané de deux composants qui doivent être conservés séparément pour éviter qu'ils ne réagissent l'un sur l'autre. Un autre domaine d'application où l'invention peut ainsi être utilisée avantageusement est par exemple celui des colles à deux composants dont l'un est destiné à provoquer le durcissement rapide de l'autre.The product return rate, that is to say the ratio between the volume of product introduced into the bag during filling and the volume extracted during use, is excellent, and can be greater than 90%. The device for packaging and dispensing fluid products according to the invention is very particularly suitable for packaging and dispensing complementary products capable of reacting with one another, which must be kept separately, and must only be mixed during their use. One field of application is that of cosmetic or dermatological compositions, such as creams and gels, which may comprise components having very different properties, for example aqueous phases and unstable oily phases, and where it may also be useful to carry out to the extemporaneous mixture of two components which must be kept separately to avoid that they react on each other. Another field of application where the invention can thus be used advantageously is for example that of two-component adhesives, one of which is intended to cause the rapid hardening of the other.
Un exemple non limitatif de réalisation de dispositif du type flacon - poche conforme à la présente invention, pour le conditionnement et la distribution de plusieurs fluides, est décrit plus en détail ci-après, en référence aux dessins annexés, qui représentent :A non-limiting example of embodiment of a device of the bottle-pouch type according to the present invention, for the packaging and distribution of several fluids, is described in more detail below, with reference to the appended drawings, which represent:
Figure 1 : une vue en coupe d'un dispositif suivant la présente invention, à deux pompes et deux poches souples, où le poussoir est en position haute, près de sa position de repos.Figure 1: a sectional view of a device according to the present invention, with two pumps and two flexible pockets, where the pusher is in the high position, near its rest position.
Figure 2 : une vue en coupe du dispositif suivant la Figure 1, le poussoir étant enfoncé.Figure 2: a sectional view of the device according to Figure 1, the pusher being pressed.
Figures ' 3A - 3C : une vue en coupe d'une variante du dispositif de 1 ' invention où les pompes et les poches sont coaxiales, une petite poche étant placée à l'intérieur de la grande poche .Figures' 3A - 3C: a sectional view of a variant of the device of the invention where the pumps and the pockets are coaxial, a small pocket being placed inside the large pocket.
Le dispositif représenté sur la Figure 1 est dans une position proche de la position de repos, où le poussoir est presque totalement relevé, à proximité de son début de course, tandis qu'il est en position basse sur la Figure 2.The device shown in Figure 1 is in a position close to the rest position, where the pusher is almost completely raised, near its start of travel, while it is in the low position in Figure 2.
Comme le montre la Figure 1, le dispositif de l'invention comprend un flacon rigide (1) dans lequel sont placées deux poches souples (2) et (3) . Les poches (2) et (3) sont fixées par leur col (4) et (5) , respectivement, à une bague (6) elle- même fixée au col (7) du flacon (1) . La bague comporte deux ouvertures permettant la fixation des deux pompes (8) et (9) communiquant avec les poches (2) et (3), respectivement.As shown in Figure 1, the device of the invention comprises a rigid bottle (1) in which are placed two flexible pockets (2) and (3). The pockets (2) and (3) are fixed by their neck (4) and (5), respectively, to a ring (6) itself fixed to the neck (7) of the bottle (1). The ring has two openings for fixing the two pumps (8) and (9) communicating with the pockets (2) and (3), respectively.
Le dispositif est complété par un poussoir (10) qui peut coulisser sur le corps (11) de la pompe (9) lorsqu'il est actionné par pression contre la résistance du ressort (12) . Le poussoir comporte encore un orifice (13) pour la sortie du produit expulsé hors des poches (2) et (3) lorsque les pompes sont actionnées comme indiqué ci-après.The device is completed by a pusher (10) which can slide on the body (11) of the pump (9) when it is actuated by pressure against the resistance of the spring (12). The pusher also has an orifice (13) for the exit of the product expelled from the pockets (2) and (3) when the pumps are actuated as indicated below.
Chacune des pompes (8) et (9) comporte un clapet infé- rieur d'obturation (14) et (15) respectivement. La pompe (8) comprend un piston (16) dans sa partie supérieure, tandis que la base (17) de la pompe 8 sert de piston pour la pompe (9) . A cet effet, la pompe (8) est montée coulissante par l'intermédiaire de son tube plongeur (18) qui peut coulisser dans l'ouverture (19) formée dans la base du corps de la pompe (9) . De manière classique, les clapets (14) et (15) sont en position de fermeture quand une pression est exercée sur le poussoir (10) contre le ressort (12) et en position d'ouverture quand le poussoir est relâché. Inversement, une pression sur le poussoir (10) provoque l'ouverture des pistons (16) et (17) , qui se referment quand le poussoir se relève sous l'action du ressort (12) .Each of the pumps (8) and (9) has a lower shutter valve (14) and (15) respectively. The pump (8) comprises a piston (16) in its upper part, while the base (17) of the pump 8 serves as a piston for the pump (9). To this end, the pump (8) is slidably mounted by means of its dip tube (18) which can slide in the opening (19) formed in the base of the pump body (9). Conventionally, the valves (14) and (15) are in the closed position when pressure is exerted on the pusher (10) against the spring (12) and in the open position when the pusher is released. Conversely, a pressure on the pusher (10) causes the pistons (16) and (17) to open, which close when the pusher is raised under the action of the spring (12).
Une arrivée d'air est assurée par les orifices (20) etAn air supply is ensured by the orifices (20) and
(21) formés dans le cylindre de la pompe (9) et dans la bague (6) respectivement, permettant à l'air extérieur de parvenir jusque dans l'espace entre la paroi interne du flacon (1) et les poches (2) et (3) lorsque le poussoir (10) est actionné.(21) formed in the pump cylinder (9) and in the ring (6) respectively, allowing the outside air to reach the space between the internal wall of the bottle (1) and the pockets (2) and (3) when the pusher (10) is actuated.
La tige (22) du piston (16) est solidaire du poussoir (10) et peut coulisser dans le cylindre (23) qui peut lui-même se déplacer dans la chambre de la pompe (8) , mais dont la course vers le haut est limitée par une butée (24) .The rod (22) of the piston (16) is integral with the pusher (10) and can slide in the cylinder (23) which can itself move in the pump chamber (8), but whose stroke upwards is limited by a stop (24).
Une autre butée (25) sur une glissière interne du poussoir (10) vient prendre appui sur le haut de la pompe (8) pour repousser celle-ci lorsque le poussoir a été déplacé sur une distance déterminée, correspondant sensiblement à la course du piston (16) . Enfin, une troisième butée (26) coopère avec le bord supérieur du cylindre (27) .Another stop (25) on an internal slide of the pusher (10) comes to bear on the top of the pump (8) to push it back when the pusher has been moved over a determined distance, corresponding substantially to the piston stroke (16). Finally, a third stop (26) cooperates with the upper edge of the cylinder (27).
Le fonctionnement du dispositif de l'invention est décrit ci-après , Lorsque l'utilisateur exerce une pression sur le poussoirThe operation of the device of the invention is described below, When the user exerts pressure on the pusher
(10) celui amorce un mouvement de descente contre l'action du ressort (12) qui prend appui sur la base du corps de la pompe(10) that initiates a downward movement against the action of the spring (12) which bears on the base of the pump body
(9) . En début de mouvement, le poussoir se trouve dans la position représentée sur le Figure 1. Le clapet inférieur (14) de la pompe (8) est fermé, de même que le clapet (15) de la pompe (9) . Au contraire, le poussoir (10) étant solidaire de la tige (22) du piston (16), ce dernier s'ouvre, et son mouvement vers le bas provoque l'expulsion du produit se trouvant dans la chambre de la pompe (8) par la lumière (28) entre le siège et la tête du piston (16) , et par le conduit(9). At the start of movement, the pusher is in the position shown in Figure 1. The lower valve (14) of the pump (8) is closed, as is the valve (15) of the pump (9). On the contrary, the pusher (10) being integral with the rod (22) of the piston (16), the latter opens, and its downward movement causes the expulsion of the product located in the pump chamber (8 ) by the light (28) between the seat and the piston head (16), and by the conduit
(29) jusqu'à la buse de sortie (13) .(29) to the outlet nozzle (13).
Lorsque le mouvement du poussoir se prolonge, le pistonWhen the movement of the pusher continues, the piston
(16) de la pompe (8) arrive en bout de course, puis l'ensemble du corps de la pompe avec le piston se déplace, libérant le piston (17) de son siège et provoquant l'expulsion du produit se trouvant dans la chambre de la pompe (9) par le conduit(16) of the pump (8) reaches the end of its travel, then the whole body of the pump with the piston moves, releasing the piston (17) from its seat and causing the expulsion of the product in the pump chamber (9) through the conduit
(30) jusqu'à la périphérie de la buse (13). En fin de course, le dispositif se trouve dans la position représentée sur la Figure 2. Ainsi, en appuyant progressivement sur le poussoir, l'utilisateur provoque successivement : le déplacement du poussoir et de la tige du piston, entraînant l'ouverture de la lumière (28) communiquant avec le conduit (29) ; puis, celui de l'ensemble du piston et du cylindre dans le corps de la pompe (8) , dès que la butée (24) entre en contact avec le bord du cylindre (23) ; et enfin celui de la pompe (8) elle-même dans la chambre de la pompe (9) .(30) to the periphery of the nozzle (13). At the end of the stroke, the device is in the position shown in Figure 2. Thus, by gradually pressing the plunger, the user successively causes: the displacement of the plunger and the piston rod, causing the opening of the light (28) communicating with the conduit (29); then that of the piston and cylinder assembly in the pump body (8), as soon as the stop (24) comes into contact with the edge of the cylinder (23); and finally that of the pump (8) itself in the pump chamber (9).
Inversement, lorsque l'utilisateur libère le poussoir (10), celui-ci se relève sous l'action du ressort (12) provoquant l'ouverture de deux clapets (14) et (15), et, simultanément la fermeture du piston (17) contre la base du cylindre (27) et du piston (16) contre le cylindre (23) . Ce mouvement provoque l'aspiration du produit contenu dans la poche (2) vers la chambre de la pompe (8) et du produit contenu dans la poche (3) vers la chambre de la pompe (9) .Conversely, when the user releases the pusher (10), it is raised under the action of the spring (12) causing the opening of two valves (14) and (15), and, simultaneously closing the piston (17) against the base of the cylinder (27) and the piston (16) against the cylinder (23). This movement causes the suction of the product contained in the pocket (2) to the pump chamber (8) and of the product contained in the pocket (3) to the pump chamber (9).
Dans le même temps, l'air extérieur passe par les orifices (20) et (21) pour pénétrer dans l'espace entre la paroi interne du flacon (1) et les poches souples (2) et (3) , permettant à celles-ci de se rétracter. La buse de sortie (13) est constituée de deux orifices annulaires concentriques. Le premier orifice (31) communique avec le conduit (26) provenant de la pompe (8) , tandis que l'orifice annulaire extérieur (32) communique avec le conduit (30) provenant de la pompe (9) . Les deux orifices (31) et (32) sont masqués par une même lamelle annulaire (33) percée en son centre, réalisée en un matériau suffisamment souple et élastique pour se déformer sous la pression des fluides sortant des pompes et se plaquer à nouveau sur les orifices lorsque la pression retombe. La Figure 3A représente une variante du dispositif de l'invention où les deux poches (2') et (3') sont placées l'une dans l'autre et communiquent avec les pompes (8') et (9') respectivement, qui sont coaxiales.At the same time, the outside air passes through the orifices (20) and (21) to penetrate into the space between the internal wall of the bottle (1) and the flexible bags (2) and (3), allowing those -this to retract. The outlet nozzle (13) consists of two concentric annular orifices. The first orifice (31) communicates with the conduit (26) coming from the pump (8), while the outer annular orifice (32) communicates with the conduit (30) coming from the pump (9). The two orifices (31) and (32) are masked by the same annular strip (33) pierced in its center, made of a material which is sufficiently flexible and elastic to deform under the pressure of the fluids leaving the pumps and to be pressed again on the orifices when the pressure drops. FIG. 3A represents a variant of the device of the invention where the two pockets (2 ') and (3') are placed one inside the other and communicate with the pumps (8 ') and (9') respectively, which are coaxial.
Trois positions successives des pompes sont représentées sur les Figures 3A, 3B et 3C respectivement, en fonction du mouvement du poussoir.Three successive pump positions are shown in Figures 3A, 3B and 3C respectively, depending on the movement of the plunger.
La Figure 3A représente le dispositif de 1 ' invention en début de course du poussoir à partir de la position de repos. Dans cette position, l'utilisateur a commencé à presser le poussoir (10) contre l'action du ressort (12) provoquant un mouvement de quelques millimètres qui entraîne le déplacement de la tige (22) du piston (16) de la pompe (9') et l'ouverture de la lumière (28) permettant l'expulsion du produit contenu dans la chambre de cette pompe. Dans cette position, la base de la pompe (91) qui forme le piston (17) de la pompe (81) ne s'est pas encore déplacé et la chambre de la pompe (8') est donc fermée .Figure 3A shows the device of one invention at the start of the pusher stroke from the rest position. In this position, the user has started to press the plunger (10) against the action of the spring (12) causing a movement of a few millimeters which causes the displacement of the rod (22) of the piston (16) of the pump ( 9 ') and the opening of the light (28) allowing the expulsion of the product contained in the chamber of this pump. In this position, the base of the pump (9 1 ) which forms the piston (17) of the pump (8 1 ) does not has not yet moved and the pump chamber (8 ') is therefore closed.
Lorsque le mouvement du poussoir se poursuit, le pistonWhen the movement of the pusher continues, the piston
(16) se déplace dans la chambre de la pompe (9') provoquant l'expulsion du produit par le conduit (29) jusqu'à la buse annulaire de sortie (31) . Puis, en fin de course du piston(16) moves in the pump chamber (9 ') causing the expulsion of the product through the conduit (29) to the annular outlet nozzle (31). Then, at the end of the piston stroke
(16) , les butées (25) et (26) sur une glissière solidaire du poussoir (10) viennent prendre appui successivement sur le haut de la pompe (9') et du cylindre (27) respectivement, et repoussent le piston (17) puis le cylindre (27) dans la pompe(16), the stops (25) and (26) on a slide secured to the pusher (10) come to bear successively on the top of the pump (9 ') and of the cylinder (27) respectively, and push back the piston (17 ) then the cylinder (27) in the pump
(8') . Dès le déplacement du piston (17), le produit contenu dans la pompe (8') peut s'échapper par le conduit (30) et il est expulsé jusqu'à la buse annulaire (32) de sortie.(8 '). As soon as the piston (17) moves, the product contained in the pump (8 ') can escape through the conduit (30) and it is expelled to the annular outlet nozzle (32).
Le mouvement se poursuit ainsi jusqu'à la position représentée sur le Figure 3B, où le déplacement des pistons (16) et (17) a libéré l'ouverture d'évacuation des produits contenus dans les chambres tandis que les clapets inférieurs (14) et (15) des pompes (9') et (8') respectivement sont fermés . Lorsque la pression est relâchée sur le poussoir (10) celui-ci remonte sous l'action du ressort (12), provoquant le mouvement inverse des pistons et des pompes. Les conduits (30) et (29) de sortie des produits se ferment successivement, provoquant l'ouverture des clapets inférieurs (15) et (14) et l'aspiration des produits contenus dans les poches (2') et (3') respectivement. La Figure 3C montre le dispositif au début du mouvement de remontée du poussoir. The movement thus continues up to the position shown in Figure 3B, where the movement of the pistons (16) and (17) has freed the opening for discharging the products contained in the chambers while the lower valves (14) and (15) pumps (9 ') and (8') respectively are closed. When the pressure is released on the pusher (10) it rises under the action of the spring (12), causing the reverse movement of the pistons and pumps. The product outlet conduits (30) and (29) close successively, causing the opening of the lower valves (15) and (14) and the suction of the products contained in the pockets (2 ') and (3') respectively. Figure 3C shows the device at the start of the push-up movement.
