The reagents can be in the form of a tablet made from compressed powdered reagents.

Description

La présente invention concerne un dispositif pour le conditionnement séparé de deux composants, leur mélange et la distribution extemporanée de celui-ci.The present invention relates to a device for separate packaging of two components, mixing and extemporaneous distribution of it.

On connaít de nombreux dispositifs de ce type, comportant deux récipients pour stocker séparément les composants et des moyens pour mettre en communication les deux récipients à la première utilisation.We know many devices of this type, comprising two containers for separately storing components and means to port the two containers to the first use.

Dans certains dispositifs connus, l'un au moins des récipients est réalisé dans une matière plastique suffisamment flexible pour permettre à l'utilisateur de distribuer le mélange en pressant ses parois.In certain known devices, at least one of the containers is made of sufficiently plastic flexible to allow the user to dispense the mixture pressing its walls.

D'autres dispositifs connus comportent un organe mobile permettant à l'utilisateur de créer une surpression à l'intérieur des récipients à chaque fois qu'il faut distribuer une dose prédéterminée de mélange.Other known devices include a movable member allowing the user to create an overpressure inside containers whenever a dose needs to be dispensed predetermined mixing.

La demande de brevet européen EP-A-0239851 décrit un récipient pressurisé pour la distribution d'une mousse de polyuréthane, comportant un durcisseur et un activateur de polymérisation logés dans deux compartiments séparés à l'intérieur du récipient contenant la mousse.European patent application EP-A-0239851 describes a pressurized container for dispensing foam polyurethane, comprising a hardener and an activator polymerization housed in two separate compartments inside of the container containing the foam.

Le brevet US 3 718 236 décrit un récipient comportant une poche intérieure dans laquelle a lieu un dégagement de gaz permettant de pressuriser le liquide contenu dans le récipient autour de la poche.US Patent 3,718,236 describes a container having a inner pocket in which a release of gas takes place to pressurize the liquid in the container around the pocket.

La présente invention a pour objet de proposer un nouveau dispositif pour le conditionnement séparé de deux composants à mélanger extemporanément et la distribution du mélange obtenu, qui permette d'accroítre encore le confort d'utilisation.The object of the present invention is to propose a new device for the separate packaging of two components to mix immediately and distribute the resulting mixture, which allows to further increase the comfort of use.

Elle y parvient grâce au fait que le dispositif comporte des moyens pour, lors de la mise en communication des deux récipients, provoquer automatiquement la mise en pression du mélange obtenu, et une valve permettant à l'utilisateur de commander la distribution du mélange sous la pression ainsi produite. It achieves this thanks to the fact that the device includes means for, when the two containers are placed in communication, automatically pressurize the mixture obtained, and a valve allowing the user to control the distribution of the mixture under the pressure thus produced.

Grâce à l'invention, la distribution du mélange s'effectue sans qu'il soit nécessaire de presser les parois de l'un des récipients, de pressuriser au préalable l'un de ces derniers ou de prévoir une poche intérieure destinée à recevoir un dégagement de gaz.Thanks to the invention, the mixture is dispensed without the need to press the walls of one of the containers, first pressurize one of them or provide an interior pocket intended to receive a clearance of gas.

En outre, l'utilisateur peut distribuer la quantité qu'il souhaite en actionnant simplement la valve pendant la durée nécessaire, alors que dans les dispositifs connus utilisant un organe mobile pour distribuer une quantité prédéterminée de mélange, l'utilisateur pourrait avoir à exercer des actions répétées sur cet organe pour distribuer la quantité équivalente.In addition, the user can distribute the amount he wish by simply actuating the valve for the duration necessary, whereas in known devices using a movable member for dispensing a predetermined quantity of mixture, the user may have to perform repeated actions on this organ for distributing the equivalent quantity.

Dans un mode de réalisation particulier, les moyens pour assurer la mise en pression du mélange obtenu comportent une composition effervescente qui se trouve à l'état inactif pendant le stockage séparé des composants.In a particular embodiment, the means for ensuring the pressurization of the mixture obtained include a effervescent composition which is in the inactive state during separate storage of components.

Dans une variante préférée de ce mode de réalisation, la composition effervescente comporte au moins un réactif solide ou liquide contenu dans un logement attenant à l'un des récipients avant la première utilisation.In a preferred variant of this embodiment, the effervescent composition comprises at least one solid reagent or liquid contained in a housing adjoining one of the receptacles before first use.

Dans une réalisation particulière, ce ou ces réactifs sont enrobés totalement ou partiellement par un matériau soluble dans l'un au moins des composants.In a particular embodiment, this or these reagents are totally or partially coated with a material soluble in at least one of the components.

De préférence, la composition effervescente comporte deux réactifs solides contenus dans un logement attenant à l'un des récipients avant la première utilisation, ces deux réactifs entrant en réaction au contact dudit mélange pour dégager un gaz propulseur, par exemple du CO2.Preferably, the effervescent composition comprises two solid reagents contained in a housing adjoining one of the containers before the first use, these two reagents coming into reaction on contact with said mixture to release a propellant gas, for example CO 2 .

De préférence, ces réactifs sont pulvérulents et compactés sous la forme d'un comprimé.Preferably, these reagents are powdery and compacted in the form of a tablet.

D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre, de deux exemples de réalisation non limitatifs de l'invention, et à l'examen du dessin annexé sur lequel :

  • la figure 1 représente un premier exemple de dispositif conforme à l'invention, avant le mélange des composants,
  • la figure 2 représente le dispositif de la figure 1 immédiatement après le mélange des composants,
  • la figure 3 représente le dispositif de la figure 2 lors de la distribution du mélange et,
  • la figure 4 représente un deuxième exemple de dispositif conforme à l'invention, avant le mélange des composants.
Other characteristics and advantages of the present invention will appear on reading the detailed description which follows, of two nonlimiting exemplary embodiments of the invention, and on examining the appended drawing in which:
  • FIG. 1 represents a first example of a device according to the invention, before the components are mixed,
  • FIG. 2 represents the device of FIG. 1 immediately after the components have been mixed,
  • FIG. 3 represents the device of FIG. 2 during the distribution of the mixture and,
  • FIG. 4 represents a second example of a device according to the invention, before the components are mixed.

Le dispositif 1 représenté sur la figure 1 comporte un récipient supérieur 2 et un récipient inférieur 3 contenant respectivement deux composants liquides A et B à stocker séparément et à mélanger extemporanément.The device 1 shown in Figure 1 includes a upper container 2 and a lower container 3 containing respectively two liquid components A and B to be stored separately and mix immediately.

Le récipient supérieur 2 comporte en partie inférieure une cheminée 4, filetée intérieurement et fermée à son extrémité supérieure par un opercule amovible 5, retenu par friction dans la cheminée 4.The upper container 2 has in the lower part a chimney 4, internally threaded and closed at its end upper by a removable cover 5, retained by friction in the chimney 4.

Le récipient inférieur 3 est muni d'un col 6 fileté extérieurement et adapté à être vissé de façon étanche dans la cheminée 4 lors de l'utilisation du dispositif 1.The lower container 3 is provided with a threaded neck 6 externally and adapted to be tightly screwed into the chimney 4 when using the device 1.

Sur la figure 1, on a représenté le récipient inférieur 3 alors qu'il est partiellement vissé dans la cheminée 4 du récipient supérieur 2.In Figure 1, there is shown the lower container 3 while it is partially screwed into the chimney 4 of the container higher 2.

Pendant le stockage, le récipient inférieur 3 est fermé par un capuchon de fermeture vissé sur le col 6, qui n'a pas été représenté sur le dessin.During storage, the lower container 3 is closed by a closure cap screwed onto the neck 6, which has not been shown in the drawing.

Le récipient supérieur 2 est équipé à sa partie supérieure d'une valve 7 connue en elle-même, munie d'une tête de distribution 8.The upper container 2 is equipped at its upper part a valve 7 known in itself, provided with a dispensing head 8.

Le dispositif 1 est destiné, dans l'exemple de réalisation décrit, à être utilisé tête en bas de manière à autoriser une vidange complète de son contenu.The device 1 is intended, in the exemplary embodiment described, to be used upside down so as to allow a complete emptying of its contents.

L'opercule 5 présente, sur sa face inférieure, un renfoncement 9 qui définit un logement 13 contenant une composition effervescente se présentant dans l'exemple décrit sous la forme d'un comprimé 10.The cover 5 has, on its underside, a recess 9 which defines a housing 13 containing a composition effervescent in the example described in the form of a tablet 10.

Cette composition effervescente constitue des moyens pour assurer une mise en pression.This effervescent composition constitutes means for ensure pressurization.

Ce comprimé 10 est enrobé d'un matériau soluble dans le mélange M des composants A et B, constituant une enveloppe 11. Cette enveloppe 11 sert à protéger le comprimé 10 vis-à-vis de l'air ambiant, et également à le faire adhérer à l'opercule 5. This tablet 10 is coated with a material soluble in the mixture M of components A and B, constituting an envelope 11. This envelope 11 is used to protect the tablet 10 from air ambient, and also to make it adhere to the cover 5.

Lorsque l'un au moins des composants A et B est une solution aqueuse, l'enveloppe 11 est réalisée en un matériau hydrosoluble tel que par exemple de l'alcool polyvinylique.When at least one of components A and B is a solution aqueous, the envelope 11 is made of a water-soluble material such than for example polyvinyl alcohol.

Le comprimé 10 contient deux réactifs pulvérulents X et Y compactés ensemble à l'état déshydraté, de sorte qu'ils ne réagissent pas entre eux.Tablet 10 contains two powder reagents X and Y compacted together in the dehydrated state, so that they do not not react to each other.

Par contre, lorsqu'ils se dissolvent dans le mélange M des composants A et B, ils réagissent pour dégager un gaz, par exemple du CO2.On the other hand, when they dissolve in the mixture M of components A and B, they react to release a gas, for example CO 2 .

Le réactif X est par exemple de l'acide citrique et le réactif Y du bicarbonate de sodium.The reagent X is for example citric acid and the sodium bicarbonate reagent Y.

Bien entendu, on ne sort pas du cadre de la présente invention en utilisant d'autres réactifs X et Y, compatibles avec la nature chimique des composants A et B et la destination finale du mélange M.Of course, it is not beyond the scope of this invention using other reagents X and Y, compatible with the chemical nature of components A and B and the final destination of the mix M.

Lors de la première utilisation, l'utilisateur visse le récipient inférieur 3 dans le récipient supérieur 2.During the first use, the user screws the lower container 3 in upper container 2.

Le col 6 exerce une poussée vers le haut sur l'opercule 5 qui est ainsi délogé de la cheminée 4, de sorte que le composant A peut s'écouler dans le récipient inférieur 3 et se mélanger au composant B, produisant le mélange M.The neck 6 pushes upward on the cover 5 which is thus dislodged from the chimney 4, so that the component A can flow into the lower container 3 and mix with the component B, producing the mixture M.

L'enveloppe 11 se dissout au contact du mélange M et le comprimé 11 entre ainsi en contact direct avec le mélange M.The envelope 11 dissolves on contact with the mixture M and the tablet 11 thus comes into direct contact with the mixture M.

Les réactifs X et Y constituant le comprimé 11 se dissolvent dans le mélange M et réagissent pour dégager un gaz G qui s'accumule au-dessus du mélange dans le récipient supérieur 2 et met ce mélange sous pression. On a représenté sur la figure 3 le dispositif 1 après la dissolution complète du comprimé 10.The reagents X and Y constituting the tablet 11 dissolve in the mixture M and react to give off a gas G which accumulates above the mixture in the upper container 2 and puts this mixture under pressure. FIG. 3 shows the device 1 after complete dissolution of the tablet 10.

Le gaz propulseur G présent au-dessus du mélange M assure la distribution de celui-ci lorsque l'utilisateur appuie sur la tête de distribution 8, après avoir retourné le dispositif tête en bas, comme illustré sur la figure 3.The propellant G present above the mixture M ensures the distribution of it when the user presses the head of distribution 8, after turning the device upside down, as illustrated in figure 3.

Le gaz propulseur est en quantité suffisante pour permettre à l'utilisateur de distribuer la totalité du mélange M.The propellant is in sufficient quantity to allow the user to dispense the entire mixture M.

On a représenté sur la figure 4 un dispositif 1' conforme à une variante de mise en oeuvre de l'invention. FIG. 4 shows a device 1 'conforming to a variant implementation of the invention.

Ce dispositif 1' diffère de celui précédemment décrit par la présence d'une membrane 12 dans la cheminée 4, sous l'opercule 5, pour isoler le comprimé 10 de l'extérieur pendant le stockage séparé des composants.This device 1 'differs from that previously described by the presence of a membrane 12 in the chimney 4, under the cover 5, to isolate tablet 10 from the outside during separate storage components.

Cette membrane 12 est réalisée dans un matériau et/ou avec une épaisseur lui permettant d'être déchirée par le col 6 lorsque ce dernier est vissé dans la cheminée 4.This membrane 12 is made of a material and / or with a thickness allowing it to be torn by the neck 6 when this the latter is screwed into the chimney 4.

La présence de la membrane 12 permet d'abriter le comprimé 10 de l'air ambiant et de le maintenir dans son logement sans qu'il soit nécessaire de l'enrober d'une enveloppe protectrice 11.The presence of the membrane 12 makes it possible to shelter the tablet 10 ambient air and keep it in its housing without it it is necessary to coat it with a protective envelope 11.

Bien entendu, l'invention n'est pas limitée aux deux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the two examples which have just been described.

Dans une variante non représentée, les réactifs X et Y qui dégagent le gaz propulseur G peuvent être stockés sous forme liquide ou solide séparément, l'un directement avec le composant A et l'autre directement avec le composant B, de sorte qu'ils ne se trouvent en contact l'un de l'autre qu'après le mélange des composants A et B.In a variant not shown, the reagents X and Y which give off propellant G can be stored in liquid form or solid separately, one directly with component A and the other directly with component B, so that they don't come into contact with each other only after mixing the components A and B.

Cette solution ne convient bien entendu que si d'une part le stockage prolongé du composant A avec le réactif X en solution et d'autre part le stockage prolongé du composant B avec le réactif Y en solution est possible.This solution is of course only suitable if on the one hand the prolonged storage of component A with reagent X in solution and on the other hand the prolonged storage of component B with the reagent Y in solution is possible.

Dans une autre variante non représentée, le réactif X est stocké directement avec l'un des composants A ou B et le réactif Y se présente sous la forme d'une poudre compactée ou non, contenue isolément dans un logement à l'intérieur de la cheminée 4, à l'instar du comprimé 10.In another variant not shown, the reagent X is stored directly with one of components A or B and reagent Y comes in the form of a powder, compacted or not, contained individually in a housing inside the chimney 4, at like tablet 10.

Ce réactif Y peut le cas échéant être enrobé d'un matériau soluble dans l'un des composants A ou B.This reagent Y can if necessary be coated with a material soluble in one of the components A or B.

Dans une autre variante non représentée, les réactifs X et Y sont contenus à l'état solide dans le récipient supérieur 2, en étant isolés du composant A par une enveloppe réalisée dans un matériau insoluble dans le composant A mais soluble dans le composant B.In another variant not shown, the reagents X and Y are contained in the solid state in the upper container 2, in being isolated from component A by an envelope made in a material insoluble in component A but soluble in component B.

Lors du mélange des composants, cette enveloppe se dissout dans le composant B, de sorte que les réactifs X et Y entrent au contact du mélange M et réagissent pour dégager le gaz propulseur. When the components are mixed, this envelope dissolves in component B, so that reagents X and Y enter at contact with the mixture M and react to release the propellant gas.

En variante, les réactifs X et Y sont contenus de manière analogue dans le récipient inférieur 3, en étant enrobés d'un matériau soluble dans le composant A mais insoluble dans le composant B.Alternatively, the reagents X and Y are contained so similar in the lower container 3, being coated with a material soluble in component A but insoluble in component B.

Dans une autre variante non représentée, l'un des réactifs X ou Y est présent, à l'état liquide ou solide, dans le récipient supérieur 2, en étant isolé du composant A par une enveloppe insoluble dans le composant A mais soluble dans le composant B et l'autre réactif est présent dans le récipient inférieur 3, soit en solution avec le composant B soit isolé de ce dernier par une enveloppe insoluble dans le composant B mais soluble dans le composant A.In another variant not shown, one of the reagents X or Y is present, in liquid or solid state, in the container upper 2, being isolated from component A by an envelope insoluble in component A but soluble in component B and the other reagent is present in the lower container 3, i.e. solution with component B be isolated from it by a envelope insoluble in component B but soluble in component A.

Lors du mélange des composants A et B, l'enveloppe renfermant le réactif X se dissout au contact du mélange M ainsi que l'enveloppe renfermant le réactif Y le cas échéant.When mixing components A and B, the envelope containing reagent X dissolves on contact with mixture M as well as the envelope containing the reagent Y if applicable.

Les réactifs X et Y réagissent alors pour dégager le gaz propulseur.Reagents X and Y then react to release the gas propellant.

Finalement, l'invention offre un moyen économique permettant de distribuer le mélange M sous la pression d'un gaz propulseur avec un confort d'utilisation accru par rapport aux dispositifs connus.Finally, the invention offers an economical means allowing to distribute the mixture M under the pressure of a propellant gas with increased user comfort compared to known devices.

Comme réactifs X et Y, on peut utiliser tous produits compatibles avec la destination du mélange M, comme expliqué plus haut, ces réactifs pouvant être enrobés ou non, ensemble ou isolément, par tout matériau approprié. Le rôle de l'un des réactifs X et Y pourrait encore être joué par l'un des composants A et B si la nature chimique de celui-ci le permet.As reagents X and Y, all products can be used compatible with the destination of the mixture M, as explained more high, these reagents may or may not be coated, together or in isolation, by any suitable material. The role of one of the reagents X and Y could still be played by one of the components A and B if the chemical nature of it allows it.

Le gaz propulseur G est de préférence du dioxide de carbone, inerte vis-à-vis de l'environnement, ce qui présente un avantage par rapport aux gaz propulseurs inflammables ou susceptibles de détruire la couche d'ozone utilisés dans certains dispositifs de pulvérisation connus.The propellant G is preferably carbon dioxide, inert towards the environment, which has an advantage by compared to propellants that are flammable or likely to destroy the ozone layer used in some devices known spraying.

Les récipients contenant les composants A et B peuvent être livrés à l'utilisateur déjà assujettis l'un à l'autre, avec des moyens permettant de les faire communiquer en tournant l'un par rapport à l'autre par exemple. Containers containing components A and B can be delivered to the user already subject to each other, with means allowing them to communicate by turning one by compared to the other for example.

Les composants A et B sont par exemple un colorant et un excipient qui permettent d'obtenir, lorsque mélangés, une teinture capillaire.Components A and B are for example a dye and a excipient which makes it possible to obtain, when mixed, a tincture capillary.
