Description

La présente invention concerne un récipient permettant le stockage d'au moins deux produits, le mélange de ces produits et la distribution du mélange ainsi obtenu.The present invention relates to a container allowing the storage of at least two products, the mixing of these products and the distribution of the mixture thus obtained.

On connaît, notamment par FR-A-2.129.079, un tel récipient comportant un premier réservoir apte à contenir un produit liquide muni d'un orifice de distribution, un second réservoir cylindrique apte à contenir un produit pulvérulent, comportant un fond et une embouchure fixe par rapport au premier réservoir et par laquelle il est contigu au premier réservoir, une paroi amovible obturant l'embouchure du second réservoir, et une pièce cylindrique mobile, de section extérieure voisine de la section intérieure du second réservoir et ayant une course limitée entre une première position dans laquelle elle se situe en dehors du premier réservoir, et une seconde position dans laquelle elle pénètre dans le premier réservoir, en écartant la paroi amovible pour mettre ainsi en cummunication les deux réservoirs.We know, in particular from FR-A-2,129,079, such a container comprising a first reservoir capable of containing a liquid product provided with a dispensing orifice, a second cylindrical reservoir capable of containing a pulverulent product, comprising a bottom and a mouth fixed with respect to the first tank and by which it is contiguous to the first tank, a removable wall closing off the mouth of the second tank, and a movable cylindrical part, of external section close to the internal section of the second tank and having a limited stroke between a first position in which it is located outside the first tank, and a second position in which it enters the first tank, by moving the removable wall apart so as to put the two tanks into communication.

Un tel récipient présente l'avantage de pouvoir contenir séparément un premier produit, par exemple un liquide, dans le premier réservoir, et un second produit, par exemple une poudre, dans le second réservoir.Such a container has the advantage of being able to contain a first product, for example a liquid, in the first tank, and a second product, for example a powder, in the second tank.

Ainsi conditionnés, les deux produits peuvent se conserver pendant de longues périodes, ce qui ne serait pas possible s'ils étaient mélangés dès leur introduction dans le récipient.Thus conditioned, the two products can be stored for long periods, which would not be possible if they were mixed as soon as they were introduced into the container.

Ce récipient connu présente toutefois un certain nombre d'inconvénients.This known container, however, has a number of drawbacks.

En particulier, il comporte un nombre important de pièces, ce qui rend sa fabrication difficile et coûteuse.In particular, it comprises a large number of parts, which makes its manufacture difficult and expensive.

En outre, son agencement est tel que lors du mélange des deux produits, il est nécessaire de positionner le récipient de manière à ce que le second réservoir se trouve au-dessus du premier afin d'éviter que le mélange ne se produise à l'intérieur du second réservoir, dont le petit volume est peu propice à une bonne homogénéisation du mélange.In addition, its arrangement is such that when mixing the two products, it is necessary to position the container so that the second tank is located above the first in order to avoid mixing occurring. inside the second tank, whose small volume is not very conducive to good homogenization of the mixture.

De plus, lorsque le second réservoir renferme une poudre, l'introduction d'un liquide provenant du premier réservoir dans le second réservoir provoque la formation de mottes de poudre qui peuvent s'agglutiner dans le second réservoir.In addition, when the second reservoir contains a powder, the introduction of a liquid from the first reservoir into the second reservoir causes the formation of lumps of powder which can clump together in the second reservoir.

La présente invention vise à fournir un récipient qui évite notamment les inconvénients rappelés ci-dessus.The present invention aims to provide a container which in particular avoids the drawbacks mentioned above.

La présente invention a pour objet un récipient permettant le stockage d'au moins deux produits, le mélange de ces produits et la distribution du mélange ainsi obtenu, comportant un premier réservoir apte à contenir un produit liquide muni d'un orifice de distribution, un second réservoir cylindrique apte à contenir un produit pulvérulent, comportant un fond et une embouchure fixe par rapport au premier réservoir et par laquelle il est contigu au premier réservoir, une paroi amovible obturant l'embouchure du second réservoir, et une pièce cylindrique mobile, de section extérieure voisine de la section intérieure du second réservoir et ayant une course limitée entre une première position dans laquelle elle se situe en dehors du premier réservoir, et une seconde position dans laquelle elle pénètre dans le premier réservoir, en écartant la paroi amovible, caractérisé par le fait que la pièce mobile comporte une paroi transversale qui constitue le fond du second réservoir, et se situe, lorsque la pièce mobile se trouve dans sa première position, à une distance de l'embouchure du second réservoir sensiblement égale ou inférieure à la course de ladite pièce mobile.The subject of the present invention is a container allowing the storage of at least two products, the mixing of these products and the distribution of the mixture thus obtained, comprising a first reservoir capable of containing a liquid product provided with a dispensing orifice, a second cylindrical reservoir capable of containing a pulverulent product, comprising a bottom and a fixed mouth relative to the first reservoir and by which it is contiguous to the first reservoir, a removable wall closing the mouth of the second reservoir, and a movable cylindrical part, outer section close to the inner section of the second tank and having a limited stroke between a first position in which it is located outside the first tank, and a second position in which it enters the first tank, spreading the removable wall, characterized by the fact that the moving part has a transverse wall which constitutes the bottom of the second r tank, and is located, when the moving part is in its first position, at a distance from the mouth of the second tank substantially equal to or less than the stroke of said moving part.

On comprend que, lors du déplacement de la pièce mobile dans sa seconde position, le volume du second réservoir se réduit jusqu'à devenir nul, de sorte que le produit contenu dans le second réservoir est chassé vers le premier et les deux produits contenus dans les réservoirs respectifs se mélangent convenablement, quelle que soit l'orientation du récipient.It is understood that, during the displacement of the moving part in its second position, the volume of the second reservoir is reduced until it becomes zero, so that the product contained in the second reservoir is expelled towards the first and the two products contained in the respective tanks mix well, regardless of the orientation of the container.

Selon l'invention, on entend par cylindrique une forme engendrée par déplacement d'une droite parallèlement à une direction donnée, le long d'un contour fermé donné.According to the invention, by cylindrical is meant a shape generated by displacement of a straight line parallel to a given direction, along a given closed contour.

Il est bien entendu que ce contour peut être notamment circulaire, mais également oval, carré, rectangulaire etc...It is understood that this outline can be in particular circular, but also oval, square, rectangular, etc.

Dans un premier mode de réalisation de l'invention, la paroi transversale de la pièce mobile est plane et entourée d'un bord dont l'extrémité supérieure se situe dans un plan incliné par rapport à un plan perpendiculaire à la direction de déplacement de la pièce mobile.In a first embodiment of the invention, the transverse wall of the moving part is planar and surrounded by an edge whose the upper end is located in an inclined plane with respect to a plane perpendicular to the direction of movement of the moving part.

Dans ce mode de réalisation, la forme globalement biseautée du bord facilite l'élimination de la paroi amovible.In this embodiment, the generally bevelled shape of the edge facilitates the elimination of the removable wall.

Dans un deuxième mode de réalisation de l'invention, la paroi transversale de la pièce mobile est perpendiculaire à la direction de déplacement de cette dernière, mais comporte de préférence une excroissance qui sert de perforateur de la paroi amovible.In a second embodiment of the invention, the transverse wall of the movable part is perpendicular to the direction of movement of the latter, but preferably comprises a projection which serves as a perforator of the removable wall.

Dans un troisième mode de réalisation, le second réservoir présente une section intérieure circulaire et la paroi transversale de la pièce mobile est agencée pour recevoir une bille sensiblement de même diamètre que la pièce mobile.In a third embodiment, the second reservoir has a circular inner section and the transverse wall of the moving part is arranged to receive a ball substantially of the same diameter as the moving part.

Ainsi, le produit du second réservoir est initialement contenu entre la paroi amovible et la bille. De cette manière, le passage de la pièce mobile dans sa seconde position provoque l'éjection de la bille, et par suite, l'évacuation complète du produit dans le premier réservoir.Thus, the product of the second reservoir is initially contained between the removable wall and the ball. In this way, the passage of the moving part in its second position causes the ejection of the ball, and consequently, the complete evacuation of the product in the first reservoir.

La bille ainsi libérée peut alors jouer son rôle conventionnel de mélangeur.The ball thus released can then play its conventional role of mixer.

Selon un mode de réalisation préféré de l'invention, la distribution du mélange est assurée par une pompe montée sur le récipient.According to a preferred embodiment of the invention, the distribution of the mixture is ensured by a pump mounted on the container.

Dans une première variante, cette pompe est logée au voisinage de l'orifice de distribution du premier réservoir.In a first variant, this pump is housed in the vicinity of the dispensing orifice of the first tank.

Dans une seconde variante, un organe de rappel est prévu pour ramener la pièce mobile dans sa première position.In a second variant, a return member is provided to return the movable part to its first position.

Dans cette dernière variante, après réalisation du mélange des deux produits par élimination de la paroi amovible, la pièce mobile joue le rôle d'un piston apte à créer une surpression dans le premier réservoir, laquelle surpression provoque l'éjection d'une dose prédéterminée de mélange par l'orifice de distribution du récipient.In this latter variant, after the two products have been mixed by eliminating the removable wall, the moving part plays the role of a piston capable of creating an overpressure in the first reservoir, which overpressure causes the ejection of a predetermined dose of mixing through the dispensing orifice of the container.

L'organe de rappel utilisable à cet effet peut être par exemple un ressort hélicoïdal ou un soufflet ménagé dans la paroi latérale d'une pièce supportant la pièce mobile.The return member which can be used for this purpose may for example be a helical spring or a bellows formed in the side wall of a part supporting the movable part.

Selon l'invention, il est également possible de prévoir un récipient dont les parois sont élastiquement déformables par pression externe, de sorte que l'éjection du produit contenu dans le premier réservoir peut être simplement obtenue en écrasant légèrement les parois latérales du récipient. Dans un tel cas, il est inutile de munir le récipient d'une pompe.According to the invention, it is also possible to provide a container whose walls are elastically deformable by pressure external, so that the ejection of the product contained in the first tank can be simply obtained by slightly crushing the side walls of the container. In such a case, there is no need to provide the container with a pump.

Dans le but de mieux faire comprendre l'invention on va en décrire maintenant des modes de réalisation donnés à titre d'exemples non limitatifs en référence au dessin annexé dans lequel :

Le récipient de la figure 1 comporte un flacon de forme générale cylindrique, qui définit un premier réservoir 1 et est muni à sa partie supérieure d'un mécanisme à poussoir 2 qui permet, par une pompe non représentée, de délivrer une dose d'un produit contenu dans le réservoir 1 au travers d'un orifice de distribution 3.The container of Figure 1 comprises a generally cylindrical bottle, which defines a first reservoir 1 and is provided at its upper part with a push mechanism 2 which allows, by a pump not shown, to deliver a dose of a product contained in the reservoir 1 through a dispensing orifice 3.

Ledit flacon est réalisé en matière plastique injectée, par exemple en polypropylène.Said bottle is made of injected plastic, for example polypropylene.

A sa partie inférieure, le flacon comporte une base 4 également réalisée en polypropylène qui est solidarisée au flacon par encliquetage.At its lower part, the bottle has a base 4 also made of polypropylene which is secured to the bottle by snap-fastening.

La base 4 comporte des lèvres d'étanchéité 5 qui prennent appui contre la paroi intérieure du flacon 1 et assurent l'étanchéité de ce dernier.The base 4 has sealing lips 5 which bear against the inner wall of the bottle 1 and seal the latter.

La base 4 comporte, dans sa partie centrale, une cheminée cylindrique 6 qui constitue les parois latérales d'un second réservoir 7 au sens de l'invention.The base 4 comprises, in its central part, a cylindrical chimney 6 which constitutes the side walls of a second tank 7 within the meaning of the invention.

Un opercule étanche 8, thermosoudé sur la base 4, sépare les deux réservoirs 1 et 7 en obturant l'embouchure du second réservoir 7. Cette dernière est fixe par rapport au premier réservoir 1.A sealed cover 8, heat-sealed on the base 4, separates the two reservoirs 1 and 7 by closing the mouth of the second reservoir 7. The latter is fixed relative to the first reservoir 1.

Un poussoir 9 vient coiffer la partie inférieure de la base 4 sur laquelle il est retenu par un renflement annulaire intérieur 10a de sa paroi latérale 11, à l'intérieur d'une gorge 12 prévue sur la base 4 et terminée par une nervure 10b.A pusher 9 covers the lower part of the base 4 on which it is retained by an internal annular bulge 10 a of its side wall 11, inside a groove 12 provided on the base 4 and terminated by a rib 10 b .

Le poussoir 9 comporte, dans sa partie centrale, un piston 13 dont la section extérieure est voisine de la section intérieure de la cheminée 6 et qui constitue la pièce mobile au sens de l'invention.The pusher 9 comprises, in its central part, a piston 13 whose external section is close to the internal section of the chimney 6 and which constitutes the movable part within the meaning of the invention.

Le piston 13 comporte une paroi plane 14 qui est entourée par un bord 15 dont l'extrémité supérieure se situe dans un plan incliné par rapport à un plan perpendiculaire à la direction de déplacement du piston 13.The piston 13 has a flat wall 14 which is surrounded by an edge 15 the upper end of which lies in a plane inclined with respect to a plane perpendicular to the direction of movement of the piston 13.

On voit, sur la figure 1, que le réservoir 1 contient un liquide 16 tandis que le réservoir 7 contient une poudre 17.It can be seen in FIG. 1 that the reservoir 1 contains a liquid 16 while the reservoir 7 contains a powder 17.

Le récipient de la figure 1 s'utilise comme décrit ci-après.The container of Figure 1 is used as described below.

Pour la conservation des produits 16 et 17, le récipient est maintenu dans la position qui est représentée sur la figure 1.For the conservation of products 16 and 17, the container is kept in the position which is shown in FIG. 1.

Pour mélanger les deux produits, on exerce une pression sur le poussoir 9 pour le déplacer en direction de l'orifice de distribution 3 du récipient.To mix the two products, pressure is exerted on the pusher 9 to move it in the direction of the dispensing orifice 3 of the container.

Le piston 13 se déplace alors dans la cheminée 6, le bord 15 venant découper l'opercule 8, comme illustré à la figure 2.The piston 13 then moves in the chimney 6, the edge 15 coming to cut out the cover 8, as illustrated in FIG. 2.

Les produits 16 et 17 peuvent alors se mélanger dans le premier réservoir 1.The products 16 and 17 can then mix in the first tank 1.

Comme on le voit sur la figure 2, la paroi 14 vient à effleurement de la paroi intérieure du réservoir 1, de sorte que le volume du second réservoir devient nul et qu'il ne se forme aucun recoin dans lequel la poudre 17 serait susceptible de s'agglutiner.As can be seen in FIG. 2, the wall 14 comes into contact with the interior wall of the reservoir 1, so that the volume of the second reservoir becomes zero and that no recess forms in which the powder 17 is liable to clump together.

Il en résulte une bonne homogénéité du mélange ainsi obtenu.This results in good homogeneity of the mixture thus obtained.

L'opercule 8 découpé demeure dans le réservoir 1 pendant toute la durée d'utilisation du récipient en tant que distributeur du mélange.The cut-out cover 8 remains in the reservoir 1 throughout the period of use of the container as a distributor of the mixture.

Comme on le voit sur la figure 2, la base 4 comporte un bossage annulaire 18 qui permet de retenir le poussoir 9 en position rentrée après mélange des produits 16 et 17.As can be seen in FIG. 2, the base 4 has an annular boss 18 which makes it possible to retain the pusher 9 in the retracted position after mixing the products 16 and 17.

Le récipient se présente alors sous une forme compacte, ce qui facilite son utilisation, le produit étant délivré par doses obtenues par pression sur le mécanisme 2. Dans une variante, non représentée, ce dernier est remplacé par un simple embout et la distribution du produit s'effectue en pressant la paroi latérale du réservoir 1 lorsque celle-ci est réalisée dans un matériau souple.The container is then presented in a compact form, which facilitates its use, the product being delivered in doses obtained by pressure on the mechanism 2. In a variant, not shown, the latter is replaced by a simple end-piece and the distribution of the product is carried out by pressing the side wall of the reservoir 1 when the latter is made of a flexible material.

Dans le mode de réalisation représenté à la figure 3, la paroi amovible séparant le réservoir 1 et le réservoir 7 est constituée par une pellicule mince 8', moulée d'un seul tenant avec la base 4', et comportant à sa périphérie un rétrécissement d'épaisseur 19 destiné à faciliter sa désolidarisation d'avec la base 4'.In the embodiment shown in FIG. 3, the removable wall separating the reservoir 1 and the reservoir 7 is constituted by a thin film 8 ′, molded integrally with the base 4 ′, and comprising at its periphery a narrowing of thickness 19 intended to facilitate its separation from the base 4 '.

Une telle paroi amovible 8' pourrait également être mise en oeuvre dans le récipient des figures 1 et 2.Such a removable wall 8 ′ could also be used in the container of FIGS. 1 and 2.

Dans le mode de réalisation de la figure 3, le piston 13' du poussoir 9' se distingue du poussoir 13 précédemment décrit en ce qu'il comporte une paroi 14' agencée pour recevoir une bille 20 de même diamètre que la cheminée 6' de la base 4', laquelle présente ici une section intérieure circulaire.In the embodiment of Figure 3, the piston 13 'of the pusher 9' differs from the pusher 13 previously described in that it has a wall 14 'arranged to receive a ball 20 of the same diameter as the chimney 6' of the base 4 ', which here has a circular inner section.

On voit, sur la figure 3, que la poudre 17 est logée, dans le récipient 7, entre la paroi amovible 8' et la bille 20, de sorte que, lors du déplacement du poussoir 9', le piston 13' éjecte simultanément la poudre 17 et la bille 20 dans le réservoir 1, ce qui a pour effet d'empêcher toute accumulation de poudre dans le réservoir 7.It can be seen in FIG. 3 that the powder 17 is housed, in the container 7, between the removable wall 8 'and the ball 20, so that, during the movement of the pusher 9', the piston 13 'simultaneously ejects the powder 17 and the ball 20 in the reservoir 1, which has the effect of preventing any accumulation of powder in the reservoir 7.

Une fois le poussoir 9' immobilisé en position rentrée, le récipient présente également une forme compacte, et la paroi 14' vient sensiblement à effleurement de la paroi intérieure du récipient 1.Once the pusher 9 ′ is immobilized in the retracted position, the container also has a compact shape, and the wall 14 ′ comes substantially flush with the interior wall of the container 1.

Dans le mode de réalisation des figures 4 et 5, le récipient comporte, à la place de l'organe de distribution 2, un simple embout 2' de forme allongée, muni d'un orifice de distribution 3 à son extrémité supérieure.In the embodiment of Figures 4 and 5, the container comprises, in place of the dispensing member 2, a simple nozzle 2 'of elongated shape, provided with a dispensing orifice 3 at its upper end.

L'obturation de l'orifice de distribution 3 peut être obtenue par exemple à l'aide d'un capuchon non représenté.The closure of the dispensing orifice 3 can be obtained for example using a cap (not shown).

Dans ce mode de réalisation, l'embase 4 et le poussoir 9 sont identiques à ceux qui ont été décrits en référence aux figures 1 et 2.In this embodiment, the base 4 and the pusher 9 are identical to those which have been described with reference to FIGS. 1 and 2.

Le récipient comporte en outre un organe élastique constitué ici par un ressort hélicoïdal 21 logé autour de la cheminée 6 de la base 4 et du piston 13 du poussoir 9.The container also comprises an elastic member constituted here by a helical spring 21 housed around the chimney 6 of the base 4 and of the piston 13 of the pusher 9.

A son extrémité inférieure, le ressort 21 est immobilisé entre des nervures 22, 23 prévues sur la face intérieure du poussoir 9.At its lower end, the spring 21 is immobilized between ribs 22, 23 provided on the inner face of the pusher 9.

La gorge 12' de la base 4 ne comporte pas de collerette 18, à la différence de celle des modes de réalisation décrits précédemment.The groove 12 'of the base 4 does not have a collar 18, unlike that of the embodiments described above.

Le poussoir 9 est ainsi ramené en permanence par le ressort hélicoïdal 21 dans la position représentée à la figure 4.The pusher 9 is thus brought back permanently by the helical spring 21 to the position shown in FIG. 4.

Pour mélanger les deux produits 16 et 17, on procède, comme pour les modes de réalisation précédemment décrits, à l'enfoncement du poussoir 9, ce qui a pour effet de découper l'opercule 8.To mix the two products 16 and 17, one proceeds, as for the embodiments described above, to push in the pusher 9, which has the effect of cutting out the cover 8.

Une fois les deux produits 16 et 17 mélangés, on relâche le poussoir 9 lequel revient dans sa position initiale.Once the two products 16 and 17 are mixed, the pusher 9 is released which returns to its initial position.

On peut ensuite libérer l'orifice de distribution 3 et utiliser le poussoir 9 comme organe de distribution d'une dose de mélange.It is then possible to release the dispensing orifice 3 and use the pusher 9 as a member for dispensing a dose of mixture.

En effet, comme on le voit sur la figure 5, le piston 13, en se déplaçant dans la cheminée 6 d'une course définie par la distance séparant la nervure 10b et l'extrémité supérieure de la gorge 12', crée une surpression dans le réservoir 1, et provoque l'évacuation par l'orifice 3 d'une dose prédéterminée du mélange contenu dans le réservoir 1.Indeed, as can be seen in FIG. 5, the piston 13, by moving in the chimney 6 of a stroke defined by the distance separating the rib 10b and the upper end of the groove 12 ', creates an overpressure in the tank 1, and causes the evacuation through the orifice 3 of a predetermined dose of the mixture contained in the tank 1.

Ainsi, le poussoir 9 sert à la fois au mélange des produits et à la distribution d'une dose prédéterminée de ces produits.Thus, the pusher 9 is used both for mixing the products and for dispensing a predetermined dose of these products.

Dans le mode de réalisation représenté à la figure 6, on a combiné certaines des caractéristiques des modes de réalisation décrits précédemment, avec de nouvelles caractéristiques.In the embodiment shown in Figure 6, some of the features of the embodiments described above have been combined with new features.

Le réservoir 7 renferme une bille 20 qui repose sur une paroi 14' aménagée à cet effet.The reservoir 7 contains a ball 20 which rests on a wall 14 'arranged for this purpose.

Le poussoir 9' sert à la fois d'organe pour le mélange des produits et d'organe doseur.The pusher 9 ′ serves both as an organ for mixing the products and as a metering organ.

L'étanchéité de la pièce mobile 13' après élimination de la paroi amovible 8'' est accrue par la présence d'une deuxième paroi 24 qui entoure le piston 13' en réservant un espace annulaire dont les dimensions sont sensiblement les mêmes que celles de la paroi de la cheminée 6 de la base 4.The sealing of the moving part 13 ′ after elimination of the removable wall 8 ′ is increased by the presence of a second wall 24 which surrounds the piston 13 ′ by reserving an annular space whose dimensions are substantially the same as those of the wall of the chimney 6 of the base 4.

La paroi amovible 8'' peut être réalisée en un matériau adéquat à la bonne conservation des produits 6 et 7.The removable wall 8 '' can be made of a material suitable for the good conservation of products 6 and 7.

L'encliquetage de la paroi 8'' sur les bords 4'a de la base 4 est une forme possible de paroi amovible. Dans ce cas, la paroi 8'' est évacuée sans découpage, par simple séparation d'avec la base 4.The snap of the wall 8 '' on the edges 4 ' a of the base 4 is a possible form of removable wall. In this case, the wall 8 '' is removed without cutting, by simple separation from the base 4.

Sur cette figure, on a en outre représenté une bague d'inviolabilité 25, qui garantit, tant qu'elle n'est pas arrachée, que les produits 16 et 17 ne sont pas mélangés.In this figure, there is also shown a tamper-evident ring 25, which guarantees, as long as it is not torn off, that the products 16 and 17 are not mixed.

Un évent 26 permet le passage d'air entre d'une part l'espace compris entre la base 4' et le flacon et d'autre part l'extérieur.A vent 26 allows the passage of air between on the one hand the space between the base 4 'and the bottle and on the other hand the outside.

Sur la figure 7, on a représenté un récipient qui comporte les mêmes éléments que celui de la figure 6, à la différence près que le réservoir 1 n'est pas cylindrique et que la base 4, le piston 13 et le second réservoir 7 de plus petite dimension, sont situés sur la paroi avant du récipient.In Figure 7, there is shown a container which has the same elements as that of Figure 6, except that the tank 1 is not cylindrical and that the base 4, the piston 13 and the second tank 7 of smaller dimension, are located on the front wall of the container.

Il est bien entendu que les modes de réalisation qui viennent d'être décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiments which have just been described have no limiting character and that they can receive any desirable modifications without departing from the scope of the invention.

En particulier, le second réservoir peut permettre de stocker deux produits ou plus, séparés par des cloisons amovibles superposées qui seraient déchirées ou découpées par la pièce mobile au cours de son passage dans sa seconde position.In particular, the second tank may allow two or more products to be stored, separated by superimposed removable partitions which would be torn or cut by the moving part during its passage into its second position.

En outre, l'orifice de distribution peut être de toute nature, par exemple un applicateur poreux tel qu'une mousse frittée, un pinceau ou un stilligoutte.In addition, the dispensing orifice can be of any kind, for example a porous applicator such as a sintered foam, a brush or a dropper.
