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 for storing at least two products, mixing these products and dispensing the mixture thus obtained.

On connaít par la demande de brevet allemand DE-A-2 809 646, le modèle d'utilité allemand DE-U-92 09 105 et la demande de brevet allemand DE-A-36 35574 des récipients permettant le stockage de deux produits, le mélange de ces produits et la distribution du mélange ainsi obtenu. Is known from the German patent application DE-A-2809646, the German model DE-U-92 09 105 and use the German patent application DE-A-36 35 574 containers for the storage of two products, the mixture of these products and the distribution of the resulting mixture.

Ces récipients comportent deux réservoirs. These containers have two tanks.

L'un des réservoirs est apte à coulisser dans l'autre pour jouer le rôle d'un piston et distribuer le mélange. One of the tanks is suitable for sliding in the other to act as a piston and distribute the mixture.

Ces récipients constituent des cartouches à utiliser dans des pistolets munis d'un organe pour faire avancer le réservoir coulissant et ne sont pas appropriés pour la distribution d'un produit cosmétique notamment. These containers are cartridges for use in guns provided with a member for advancing the sliding tank and are not suitable for the dispensing of a cosmetic product in particular.

On connaít par ailleurs par la demande de brevet français FR-A-2 129 079, un récipient permettant le stockage d'au moins deux produits, le mélange de ces produits et la distribution du mélange ainsi obtenu. Are also known from French patent application FR-A-2,129,079, a container for storing at least two products, mixing these products and dispensing the mixture thus obtained.

Un tel récipient comporte 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, au moins pendant la distribution du mélange par rapport au premier réservoir et par laquelle il est contigu au premier réservoir. Such a container comprises a first reservoir able to contain a liquid product, provided with a dispensing orifice, a second cylindrical reservoir able to contain a powdered product, comprising a bottom and a mouth fixed, at least during dispensing of the mixture relative the first reservoir and through which it is contiguous to the first reservoir.

Le récipient comporte en outre 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. The container further comprises a removable wall closing the mouth of the second reservoir, and a movable cylindrical part adjacent outer section to the inner section of the second reservoir and having a limited travel between a first position in which it is situated outside the first reservoir and a second position in which it enters the first reservoir, by removing the removable wall to thereby cummunication in the two reservoirs.

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 to be able to separately contain a first product, for example a liquid, into the first reservoir, and a second product, for example a powder, in the second reservoir.

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, both products can be stored for long periods, which would not be possible if they were mixed as they are introduced into the container,

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

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

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 during mixing of the two products, it is necessary to position the container so that the second reservoir is located above the first in order to prevent the mixture from occurring in within the second reservoir, the small volume is not conducive to good mixing.

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 tank contains a powder, introducing a liquid from the first reservoir into the second reservoir causes the powder lumps forming that can agglutinate in the second tank,

La présente invention vise à fournir un récipient qui évite notamment les inconvénients rappelés ci-dessus. The present invention is to provide a container that particular avoid 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 r The present invention relates to a container for storing at least two products, mixing these products and dispensing the mixture thus obtained, comprising a first reservoir able to contain a liquid product provided with a dispensing orifice, second cylindrical tank adapted to contain a powdered product, having a bottom and a mouth fixed to the first tank and with which it is contiguous to the first reservoir, a removable wall closing the mouth of the second reservoir, and a movable cylindrical part of adjacent outer section to the inner section of the second reservoir and having a limited travel between a first position in which it lies outside the first reservoir, and a second position in which it enters the first reservoir, by removing the removable wall, characterized in that the moving part comprises a transverse wall which constitutes the bottom of the second r éservoir, 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 et par le fait que lorsque la pièce mobile se trouve dans sa deuxième position ladite paroi transversale se situe à proximité de ladite embouchure. reservoir and lies, when the movable piece is in its first position at a distance from the mouth of the second reservoir substantially equal to or less than the stroke of said movable part and in that when the movable piece is in its second position said transverse wall lies close to said mouth.

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 upon movement of the movable part in its second position, the volume of the second tank is reduced until it becomes zero, so that the product contained in the second reservoir is forced to the first and the two products contained in the respective reservoirs mix suitably, 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, a cylindrical form by means generated by moving 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 especially 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 flat and surrounded by an edge whose top end is in a plane inclined relative to a plane perpendicular to the direction of movement of the moving parts.

Dans ce mode de réalisation, la forme globalement biseautée du bord facilite l'élimination de la paroi amovible. In this embodiment, the generally tapered shape of the edge facilitates the removal 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 moving part is perpendicular to the direction of movement thereof, but preferably comprises a protuberance which serves 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 internal cross section and the transverse wall of the moving part is arranged to receive a ball of substantially the same diameter as the moving part.

Ainsi, le produit du second réservoir est initialement contenu entre la paroi amovible et la bille. Thus, the product of the second tank is initially contained between the removable wall and the bead. 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. In this manner, the passage of the moving part in its second position causes ejection of the ball, and as a result, 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, the pump is accommodated in the vicinity of the dispensing orifice of the first reservoir.

Dans une seconde variante, un organe de rappel est prévu pour ramener la pièce mobile dans sa première position. In a second variant, a biasing member is provided to return the movable part in 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 variant, after preparation of the mixture of the two products by removal of the movable wall, the movable member acts as a piston adapted to create an overpressure in the first reservoir, which overpressure causes the ejection of a predetermined dose mixture by the container dispensing orifice.

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 usable 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. According to the invention, it is also possible to provide a container whose walls are elastically deformable by external pressure, so that the ejection of the product contained in the first reservoir can be achieved simply by slightly crushing the side walls of the container. Dans un tel cas, il est inutile de munir le récipient d'une pompe. In such a case, it is unnecessary 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 : In order to better understand the invention now will be described embodiments given as non-limiting examples with reference to the accompanying drawings in which:

  • la figure 5 est une même vue du récipient de la figure 4 pendant une manoeuvre de distribution d'une dose de produit, Figure 5 is a same view of the container of Figure 4 during an operation of dispensing a dose of product,
  • la figure 6 est une vue analogue à la figure 1 d'un récipient selon un quatrième mode de réalisation de l'invention, et Figure 6 is a view similar to Figure 1 of a container according to a fourth embodiment of the invention, and
  • la figure 7 est une vue analogue à la figure 1 d'un récipient selon un cinquième mode de réalisation de l'invention. Figure 7 is a view similar to Figure 1 of a container according to a fifth embodiment of the invention.

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 portion a push mechanism 2 which, by a pump not shown, to deliver a dose of a product contained in the reservoir 1 through a distribution orifice 3.

Ledit flacon est réalisé en matière plastique injectée, par exemple en polypropylène. Said vial is made of injected plastic material, 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 vial has a base 4 also made of polypropylene which is secured to the vial by snapping.

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 comprises sealing lips 5 which are supported 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 shaft 6 which forms the side walls of a second reservoir 7 in the sense 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 waterproof cover 8, heat sealed to the base 4, separates the two reservoirs 1 and 7 by closing the mouth of the second reservoir 7. The latter is fixed with respect 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 10 a de sa paroi latérale 11, à l'intérieur d'une gorge 12 prévue sur la base 4 et terminée par une nervure 10 b . A pusher 9 fits over the bottom of the base 4 on which it is retained by an internal annular bulge 10 has its side wall 11, inside a groove 12 provided on the base 4 and terminating in 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 has, in its central part, a piston 13 whose outer section is close to the inner section of the shaft 6 and which constitutes the moving 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 a rim 15 whose upper end is located in a plane inclined relative to a plane perpendicular to the moving direction 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. We see in Figure 1, the tank 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 preservation of products 16 and 17, the container is held in the position shown in Figure 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. For mixing the two products, it exerts pressure on the pusher 9 to move towards the dispensing aperture 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 cutting edge 15 from the cap 8, as shown in Figure 2.

Les produits 16 et 17 peuvent alors se mélanger dans le premier réservoir 1. Items 16 and 17 may then mix in the first container 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 seen in Figure 2, the wall 14 comes to touch the inner wall of the tank 1, so that the volume of the second reservoir becomes zero and does no corner is formed in which the powder 17 is capable of clump.

Il en résulte une bonne homogénéité du mélange ainsi obtenu. The result is a good homogeneity of the mixture.

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 seal 8 remains in the reservoir 1 during the entire duration 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 seen in Figure 2, the base 4 includes an annular boss 18 which allows to retain the pusher 9 in the retracted position after mixing of 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 receptacle is then in a compact form, thereby facilitating its use, the product being delivered by dosage obtained by pressure on the mechanism 2. In a variant, not shown, the latter is replaced by a simple nozzle and product distribution is done by pressing the side wall of the tank 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 Figure 3, the movable wall separating the reservoir 1 and the container 7 is constituted by a thin film 8 'molded integrally with the base 4' and having on its periphery a constriction 19 thickness to facilitate its disconnection from the base 4 '.

Une telle paroi amovible 8' pourrait également être mise en oeuvre dans le récipient des figures 1 et 2. Such removable wall 8 'may also be implemented in the container of Figures 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 plunger 9' differs from the pusher 13 previously described in that it comprises a wall 14 'arranged to receive a ball 20 of the same diameter as the stack 6' 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. We see in Figure 3, the powder 17 is accommodated in the container 7, between the removable wall 8 'and the ball 20, so that upon movement of the plunger 9', the piston 13 simultaneously ejects the powder 17 and the ball 20 in the tank 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 immobilized in the retracted position, the container also has a compact shape, and the wall 14 substantially comes to touch the inner 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 has, instead of the dispensing member 2, a single tip 2 'of elongated shape, provided with a distribution 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 with 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 described with reference to Figures 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 further comprises an elastic member here consists of a helical spring 21 mounted around the shaft 6 of the base 4 and the piston 13 of the plunger 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 locked between the 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 has no collar 18, unlike 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 thereby reduced permanently by the coil spring 21 in the position shown in Figure 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. For mixing the two products 16 and 17, one proceeds as for the previously described embodiments, depression of the plunger 9, which has the effect of cutting 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 mixed together, releasing the pusher 9 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. Can then release the dispensing orifice 3 and the pusher 9 using as distribution member of a mixing dose.

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 10 b 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 seen in Figure 5, the piston 13, moving in the shaft 6 of a race defined by the distance between the rib 10b and the upper end of the groove 12 ', creates a pressure in the tank 1, and causes the discharge through the orifice 3 of a predetermined dose of the mixture contained in the reservoir 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 serves both to the mixture of products and 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, were combined some of the features of the embodiments described above, with new features.

Le réservoir 7 renferme une bille 20 qui repose sur une paroi 14' aménagée à cet effet. The reservoir 7 includes a ball 20 which rests on a wall 14 'provided 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 member for the mixing of products and dosing member.

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 movable part 13 'after removal 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 tube 6 'of the base 4.

La paroi amovible 8'' peut être réalisée en un matériau adéquat à la bonne conservation des produits 16 et 17. The removable wall 8 '' can be made of a suitable material for the good preservation of the products 16 and 17.

L'encliquetage de la paroi 8'' sur les bords 4' a de la base 4 est une forme possible de paroi amovible. The locking of the wall 8 '' on the edges 4 'has the base 4 is a possible form of removable wall. Dans ce cas, la paroi 8'' est évacuée sans découpage, par simple séparation d'avec la base 4, In this case, the wall 8 '' is discharged 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 On this figure, there is further shown a tamper-evident ring 25, which ensures, as it is not torn, 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 air passage between on the one hand the space between the base 4 'and the bottle and the other 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 includes the same elements as that of Figure 6, with the difference that the container 1 is not cylindrical and the base 4, the piston 13 and the second reservoir 7 smaller size, 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 described above are not limiting in nature and 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 can be used to store two or more products, separated by superposed removable partitions that are torn or cut by the movable part during its passage in the 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 may be of any nature, for example a porous applicator such as a sintered foam, a brush or a dropper.
