Description

DISTRIBUTEUR DE PRODUITS CHIMIQUEMENT INSTABLES DISTRIBUTOR OF CHEMICALLY UNSTABLE PRODUCTS
La présente invention concerne un distributeur de produits chimiquement instables qui résultent du mélange d'au moins deux composants liquides.The present invention relates to a dispenser of chemically unstable products which result from the mixture of at least two liquid components.
De tels produits instables dans le temps se rencontrent notamment dans les domaines pharmaceutique et cosmétique où ils sont qualifiés de préparations extemporanées qu'il n'est pas possible de stocker ou de conditionner sous leur forme applicative. Ainsi de manière traditionnelle, les composants sont-ils conditionnés séparément dans des réservoirs indépendants d'où ils sont prélevés et dosés avant d'être mélangés sur le lieu d'application pour former le produit final.Such products which are unstable over time are encountered in particular in the pharmaceutical and cosmetic fields where they are qualified as extemporaneous preparations which it is not possible to store or package in their application form. Thus, in the traditional way, the components are packaged separately in independent tanks from which they are taken and dosed before being mixed at the place of application to form the final product.
Cependant, cette disposition n'est pas ergonomique et n'offre pas un mode d'utilisation souple et pratique.However, this arrangement is not ergonomic and does not offer a flexible and practical mode of use.
En outre, tant le dosage équilibré que le mélange homogène des composants sont difficiles à obtenir, du fait que leurs organes de prélèvement respectifs sont indépendants.In addition, both the balanced dosage and the homogeneous mixture of the components are difficult to obtain, because their respective sampling devices are independent.
La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.The present invention aims to solve these technical problems satisfactorily.
Ce but est atteint selon l'invention, au moyen d'un distributeur, caractérisé en ce qu'il comprend un boîtier externe renfermant au moins deux compartiments hermétiques contenant chacun un composant liquide ou pâteux, et pourvus d'organes de prélèvement susceptibles d'être actionnés simultanément et conjointement par un bouton-poussoir unique et de débiter dans des conduits d'évacuation séparés ménagés à l'intérieur dudit bouton-poussoir et débouchant à l'extérieur par au moins un orifice d'éjection.This object is achieved according to the invention, by means of a dispenser, characterized in that it comprises an external housing containing at least two hermetic compartments each containing a liquid or pasty component, and provided with withdrawal members capable of be actuated simultaneously and jointly by a single push button and deliver into separate evacuation conduits formed inside said push button and opening out through at least one ejection orifice.
Selon une caractéristique avantageuse, chacun desdits compartiments est délimité, transversalement, par le fond du boîtier externe et par une douille interne de support de l'organe de prélèvement et, latéralement, par la paroi d'un élément tubulaire interne dont les extrémités sont fixées de façon étanche respectivement à ladite douille et au fond dudit boîtier. Selon une autre caractéristique, les éléments tubulaires de chaque compartiment sont réunis par une cloison mitoyenne. Selon un autre mode de réalisation spécifique, la paroi de l'élément tubulaire interne forme une chemise au moins partiellement en contact avec la paroi du boîtier externe.According to an advantageous characteristic, each of said compartments is delimited, transversely, by the bottom of the external casing and by an internal bush for supporting the sampling member and, laterally, by the wall of an internal tubular element whose ends are fixed sealingly respectively to said socket and to the bottom of said housing. According to another characteristic, the tubular elements of each compartment are joined by a dividing partition. According to another specific embodiment, the wall of the internal tubular element forms a jacket at least partially in contact with the wall of the external housing.
Selon un autre mode de réalisation, la paroi de l'élément tubulaire interne est pourvue d'un épaulement transversal permettant la fixation à distance de la paroi du boîtier externe.According to another embodiment, the wall of the internal tubular element is provided with a transverse shoulder allowing remote fixing of the wall of the external housing.
Selon encore une autre caractéristique, l'élément tubulaire possède un col destiné à recevoir la douille interne de support d'un organe de prélèvement. De préférence, les éléments tubulaires de chaque compartiment sont logés dans un carter unique.According to yet another characteristic, the tubular element has a neck intended to receive the internal support bush for a sampling member. Preferably, the tubular elements of each compartment are housed in a single housing.
Selon une variante particulière, lesdits conduits d'évacuation débouchent à l'extérieur via une portion terminale commune.According to a particular variant, said evacuation conduits open to the outside via a common terminal portion.
Selon une autre caractéristique, l'orifice d'éjection est réalisé sur un bossage en saillie sur la face latérale du bouton-poussoir.According to another characteristic, the ejection orifice is produced on a protruding boss on the lateral face of the push button.
Le distributeur de l'invention peut être utilisé avec des organes de prélèvement sous forme de pompe et/ou de valve et sans qu'il soit nécessaire de prévoir des joints d'étanchéité.The dispenser of the invention can be used with withdrawal members in the form of a pump and / or valve and without it being necessary to provide seals.
Les conduits d'évacuation des composants et, le cas échéant, leur orifice d'éjection étant séparés, il ne peut se produire de mélange à l'intérieur du distributeur, ce qui réduit les risques de colmatage et de dégradation du produit.The components' evacuation pipes and, if necessary, their ejection orifice being separated, there can be no mixing inside the dispenser, which reduces the risks of clogging and degradation of the product.
Par ailleurs, le dosage des composants est effectué de façon simple, en adaptant la capacité respective des moyens de prélèvement au rapport pondéral de chacun de ces composants dans le produit final.Furthermore, the dosing of the components is carried out in a simple manner, by adapting the respective capacity of the sampling means to the weight ratio of each of these components in the final product.
Le distributeur de l'invention permet de disposer avec un conditionnement unique, réalisable en diverses contenances, d'un moyen simple, fiable et efficace de restitution d'un produit instable bi ou plus généralement multicomposants. Le distributeur de l'invention peut être fabriqué industriellement de façon simple, rapide et économique, par exemple, en effectuant un moulage par injection de polypropylène.The dispenser of the invention makes it possible to have, with a single packaging, which can be produced in various capacities, a simple, reliable and effective means for restoring an unstable bi or more generally multicomponent product. The dispenser of the invention can be manufactured industrially in a simple, rapid and economical manner, for example, by performing an injection molding of polypropylene.
L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels : - les figures 1A et 1B représentent respectivement des vues en perspective éclatée avant assemblage et après assemblage d'un mode de réalisation du distributeur de l'invention ;The invention will be better understood on reading the description which follows, accompanied by the drawings in which: - Figures 1A and 1B respectively show exploded perspective views before assembly and after assembly of an embodiment of the dispenser of the invention;

- les figures 4A et 4B représentent des vues respectivement en coupe et de dessus d'un autre mode de réalisation du distributeur de l'invention ;- Figures 4A and 4B show views respectively in section and from above of another embodiment of the dispenser of the invention;
- les figures 5A, 5B et 5C représentent des vues respectivement de dessous, en coupe selon AA et en coupe selon BB du bouton-poussoir utilisé pour le distributeur de l'invention. Le distributeur représenté sur les figures est destiné à conditionner et à restituer des composants liquides et/ou pâteux susceptibles de former, par mélange, un produit chimiquement instable qualifié de préparation extemporanée.- Figures 5A, 5B and 5C show views respectively from below, in section along AA and in section along BB of the push button used for the dispenser of the invention. The dispenser shown in the figures is intended to condition and restore liquid and / or pasty components capable of forming, by mixing, a chemically unstable product qualified as extemporaneous preparation.
Ce distributeur comprend comme représenté sur les figures 1A et 2A, un boîtier externe 1 renfermant au moins deux, et ici, exactement deux compartiments hermétiques 11,12 contenant chacun un volume donné d'un composant liquide déterminé.This dispenser comprises, as shown in FIGS. 1A and 2A, an external housing 1 containing at least two, and here, exactly two hermetic compartments 11, 12 each containing a given volume of a determined liquid component.
Chaque compartiment 11,12 est pourvu d'un organe de prélèvement 2 du composant qui y est contenu. Les organes de prélèvement 2 sont ici constitués de pompesEach compartment 11, 12 is provided with a member 2 for removing the component contained therein. The sampling organs 2 here consist of pumps
21,22 mais selon des variantes de réalisation dans lesquelles les compartiments seraient sous pression, ces organes seraient alors formés de valves.21,22 but according to alternative embodiments in which the compartments are under pressure, these members would then be formed of valves.
Les organes de prélèvement 2 sont susceptibles d'être actionnés simultanément et conjointement par un bouton-poussoir unique 3, réalisé en une seule pièce et coiffant ici les tubes gicleur 21a,22a respectifs des pompes 21,22.The withdrawal members 2 are capable of being actuated simultaneously and jointly by a single push button 3, produced in a single piece and here covering the respective nozzle tubes 21a, 22a of the pumps 21,22.
L'appui sur le bouton-poussoir 3 provoque l'échappement des composants liquides de leur compartiment respectif et leur évacuation par des conduits séparés 31,32 débouchant à l'extérieur par au moins un et, de préférence, deux orifices d'éjection 31a,32a ménagés ici sur un bossage 30 en saillie sur la face latérale du bouton-poussoir 3.Pressing the push button 3 causes the liquid components to escape from their respective compartments and to be evacuated by separate conduits 31, 32 opening to the outside via at least one and preferably two ejection orifices 31a, 32a formed here on a boss 30 projecting from the lateral face of the push-button 3.
Dans le mode de réalisation représenté sur la figure 5A, les conduits d'évacuation 31,32 débouchent à l'extérieur, le cas échéant, via une portion terminale commune 33 participant au pré-mélange des composants.In the embodiment shown in FIG. 5A, the evacuation conduits 31, 32 open out, if necessary, via a common terminal portion 33 participating in the premixing of the components.
Chacun des compartiments est délimité, transversalement, par le fond 10 du boîtier 1 et par une douille interne 41,42 de support des organes de prélèvement et, latéralement, par la paroi d'un élément tubulaire interne 51,52. Les extrémités des éléments tubulaires sont fixées respectivement à la douille 41,42 et au fond 10 du boîtier 1.Each of the compartments is delimited, transversely, by the bottom 10 of the housing 1 and by an internal bush 41,42 for supporting the sampling members and, laterally, by the wall of an internal tubular element 51,52. The ends of the tubular elements are fixed respectively to the socket 41, 42 and to the bottom 10 of the housing 1.
Les éléments tubulaires 51,52 associés à chacun des compartiments 11,12 sont tous deux logés dans un carter unique 5.The tubular elements 51, 52 associated with each of the compartments 11, 12 are both housed in a single casing 5.
La liaison entre le fond 10 et le bord inférieur des éléments tubulaires est réalisée, de préférence, au moyen d'une soudure à platThe connection between the bottom 10 and the lower edge of the tubular elements is preferably carried out by means of a flat weld
(ultrasons...) assurant l'étanchéité entre les deux compartiments 11,12 qui sont séparés ici par une cloison mitoyenne unique 50 réunissant les deux éléments tubulaires 51,52.(ultrasound, etc.) sealing between the two compartments 11, 12 which are separated here by a single dividing partition 50 joining the two tubular elements 51, 52.
En cas d'utilisation d'organes de prélèvement "airless", les cloisons respectifs des deux compartiments 11,12 seront accolées dans la partie centrale du distributeur.If "airless" sampling devices are used, the respective partitions of the two compartments 11, 12 will be joined in the central part of the dispenser.
La liaison entre les éléments tubulaires 51,52 et les douilles 41,42 est réalisée, dans les modes représentés sur les figures 2A et 3A, par emmanchement de portées en regard avec serrage radial étanche. A cet effet, les éléments tubulaires sont pourvus d'un col cylindrique 53 destiné à recevoir les douilles.The connection between the tubular elements 51, 52 and the sockets 41, 42 is carried out, in the modes shown in FIGS. 2A and 3A, by fitting of facing spans with tight radial tightening. To this end, the tubular elements are provided with a cylindrical neck 53 intended to receive the sockets.
Plus précisément, les douilles 41,42 possèdent une jupe périphérique 41a,42a destinée à s'emmancher extérieurement sur le col 53 et délimitant dans sa partie haute, une gorge intérieure 41b,42b également périphérique qui vient coiffer le rebord supérieur du col 53.More precisely, the sockets 41, 42 have a peripheral skirt 41a, 42a intended to be fitted outwardly on the neck 53 and delimiting in its upper part, an inner groove 41b, 42b also peripheral which covers the upper edge of the neck 53.
La jupe 41a,42a se prolonge par une collerette 41c,42c représentée respectivement sur les figures 2A, 3A selon deux variantes de réalisation distinctes, et destinée à emprisonner la partie supérieure du corps des pompes 21,22. Dans la variante de la figure 3B, les douilles 41,42 sont réalisées dans le prolongement des éléments tubulaires 51,52 et d'une seule pièce avec ces derniers.The skirt 41a, 42a is extended by a flange 41c, 42c shown respectively in FIGS. 2A, 3A according to two distinct variant embodiments, and intended to trap the upper part of the body of the pumps 21,22. In the variant of FIG. 3B, the sockets 41, 42 are produced in the extension of the tubular elements 51, 52 and in one piece with the latter.
Les douilles 41,42 délimitent ainsi directement dans leur partie supérieure des cols cylindriques 53 qui servent de support aux corps des pompes 21,22.The sockets 41,42 thus directly delimit in their upper part cylindrical necks 53 which serve to support the bodies of the pumps 21,22.
Dans le mode de réalisation des figures 2A et 3, la paroi des éléments tubulaires 51,52 forme sous le col 53 une chemise au moins partiellement en contact avec la paroi interne du boîtier 1 en assurant, le cas échéant, un léger serrage radial.In the embodiment of FIGS. 2A and 3, the wall of the tubular elements 51, 52 forms under the neck 53 a jacket at least partially in contact with the internal wall of the housing 1, ensuring, if necessary, a slight radial tightening.
L'introduction des éléments tubulaires dans le boîtier 1 s'effectue alors par coulissement axial.The introduction of the tubular elements into the housing 1 is then carried out by axial sliding.
Dans le mode de réalisation de la figure 4A, la paroi latérale des éléments tubulaires 51,52 se prolonge en partie haute par un épaulement transversal 54 s'étendant radialement vers l'extérieur pour venir au contact de la paroi interne du boîtier 1 en formant entretoise de façon à permettre le positionnement et la fixation à distance de cette paroi.In the embodiment of FIG. 4A, the side wall of the tubular elements 51, 52 is extended at the top by a transverse shoulder 54 extending radially outward to come into contact with the internal wall of the housing 1, forming spacer so as to allow positioning and remote fixing of this wall.
Le bouton-poussoir 3 représenté sur les figures 5A, 5B et 5C est réalisé ici sous forme d'un capot à l'intérieur duquel sont disposés des manchons 34 venant s'ajuster sur l'extrémité externe des tubes gicleurs des pompes 21,22 et communiquant latéralement avec les conduits d'évacuation 31,32.The push button 3 shown in FIGS. 5A, 5B and 5C is produced here in the form of a cover inside of which are arranged sleeves 34 which come to fit on the external end of the nozzle tubes of the pumps 21, 22 and communicating laterally with the evacuation conduits 31,32.
La face supérieure du bouton poussoir 3 est pourvue d'une cavité 35 facilitant l'appui manuel. La partie inférieure du bouton-poussoir 3 est engagée au repos, à l'intérieur de la partie supérieure du boîtier 1 (comme représenté sur les figures 1, 2A, et 3B où elle se déplace lors de l'appui manuel actionnant les pompes 21,22 (voir figure 2B). The upper face of the push button 3 is provided with a cavity 35 facilitating manual support. The lower part of the push-button 3 is engaged at rest, inside the upper part of the housing 1 (as shown in FIGS. 1, 2A, and 3B where it moves during manual support actuating the pumps 21 , 22 (see Figure 2B).
