Description

L'invention a pour objet un récipient, pour le conditionnement séparé puis le mélange d'au moins deux produits. On sait qu'il est souvent nécessaire de réaliser un mélange de plusieurs produits au moment de l'utilisation, les produits séparés supportant bien le stockage prolongé alors que leur mélange s'altère rapidement. Un tel conditionnement peut être utilisé, par exemple, pour la commercialisation de produits pharmaceutiques, cosmétiques ou photographiques. Le récipient objet de l'invention concerne plus particulièrement le stockage et le mélange de produits s'écoulant mal, en particulier le stockage et le mélange de plusieurs produits dont au moins un est visqueux, comme par exemple le stockage et le mélange d'une poudre avec une crème ou une pâte ou de deux crèmes. On peut citer en exemple de tels produits les produits de coloration.The subject of the invention is a container, for separate packaging and then mixture of at least two products. We know that it is often necessary to make a mixture of several products at the time of use, the products separated well supporting prolonged storage while their mixture deteriorates quickly. Such packaging can be used, for example, for the marketing of pharmaceuticals, cosmetics or photographic. The object of the invention relates more particularly storage and mixing of poorly flowing products, in particular storage and the mixture of several products of which at least one is viscous, as for example storing and mixing a powder with a cream or a paste or of two creams. Examples of such products include the products of coloring.

Plusieurs conditionnements permettant un stockage séparé de deux produits et leur mise en contact juste avant l'utilisation sont déjà connus, en particulier par les documents FR-2283064, FR-2602752, FR-2396701, EP-0417998. Toutefois, ces conditionnements permettent un mélange essentiellement sous l'action de la gravité, ce qui est peu adapté au cas des produits visqueux et des poudres, produits qui s'écoulent mal.Several packaging allowing separate storage of two products and their contacting just before use are already known, in particular by documents FR-2283064, FR-2602752, FR-2396701, EP-0417998. However, these packages allow mixing essentially under the action of gravity, which is poorly suited to the case of viscous products and powders, poorly flowing products.

Plus précisément dans FR-2283064 le système proposé permet le stockage séparé d'un solide et d'un liquide qui sont isolés par une pellicule déchirable. Dans ce système l'ouverture, incomplète, entre les deux compartiments contenant chaque produit, ouverture due au déchirement de la pellicule, serait insuffisante pour permettre un mélange facile et homogène de produits, dans le cas où l'un de ces produits serait une pâte, une crème ou une poudre.More precisely in FR-2283064 the proposed system allows storage separated from a solid and a liquid which are isolated by a tearable film. In this system, the incomplete opening between the two compartments containing each product, opening due to tearing of the film, would insufficient to allow easy and homogeneous mixing of products, in the if one of these products is a paste, cream or powder.

Dans le système du document FR-2602752, l'un des produits est un liquide qui vient imprégner un tampon contenu dans une autre cavité, les deux cavités étant séparées par une pellicule déchirable. Ce conditionnement présente par conséquent les mêmes inconvénients (difficulté d'écoulement et de mélange) pour une pâte une crème ou une poudre que ceux décrits ci-dessus. In the system of document FR-2602752, one of the products is a liquid which impregnates a tampon contained in another cavity, the two cavities being separated by a tearable film. This conditioning presents by therefore the same disadvantages (difficulty of flow and mixing) for a paste a cream or a powder than those described above.

Il en est de même pour le dispositif du brevet FR-2396701. En outre les récipients selon ce brevet sont constitués de l'assemblage et du soudage de plusieurs compartiments, or le nombre de pièces élevé d'un tel récipient entraíne un surcoût non négligeable par rapport à un récipient en une seule pièce.It is the same for the device of patent FR-2396701. In addition the containers according to this patent consist of the assembly and welding of several compartments, or the high number of pieces of such a container causes a significant additional cost compared to a container in one piece.

Dans le système décrit par le document EP-0417998, le récipient comprend un compartiment supérieur de forme tubulaire, ce qui est peu favorable au mélange lorsque le produit stocké dans le compartiment supérieur est une crème et par conséquent s'écoule mal. Cette forme présente également l'inconvénient de ne pas permettre facilement le mélange des produits à l'aide d'un instrument comme une baguette ou un pinceau. Cet inconvénient est commun aux autres systèmes connus. En outre ce récipient est fabriqué par injection soufflage, qui est une technique coûteuse.In the system described by document EP-0417998, the container comprises a tubular upper compartment, which is not very favorable for mixing when the product stored in the upper compartment is a cream and by therefore flows poorly. This form also has the disadvantage of not not allow products to be easily mixed using an instrument such as a stick or a brush. This drawback is common to other systems known. In addition this container is manufactured by injection blowing, which is a expensive technique.

Les documents US-4,410,085 et WO95/23744 décrivent des dispositifs permettant le mélange simultané de deux produits contenus dans deux cavités, l'une principale, l'autre secondaire contenue dans la cavité principale, les deux cavités étant séparées par un bouchon. Toutefois, dans chacun de ces dispositifs, il est nécessaire d'ouvrir la cavité principale avant d'ouvrir la cavité secondaire. Par conséquent, une manipulation maladroite au moment de l'ouverture de la cavité secondaire fait courir le risque que le produit contenu dans la cavité principale se répande hors du récipient.Documents US-4,410,085 and WO95 / 23744 describe devices allowing the simultaneous mixing of two products contained in two cavities, one main, the other secondary contained in the main cavity, the two cavities being separated by a plug. However, in each of these devices, it is necessary to open the main cavity before opening the cavity secondary. Therefore, awkward handling at the time of opening the secondary cavity runs the risk that the product contained into the main cavity spills out of the container.

Le brevet FR-1 224 465 décrit un récipient comportant une pluralité de réservoirs concentriques. Dans un mode de réalisation, tous les récipients concentriques sont de même hauteur, et sont obturés par le même couvercle. Une telle conception rend difficile le mélange des différentes compositions qu'il contient.Patent FR-1 224 465 describes a container comprising a plurality of reservoirs concentric. In one embodiment, all of the concentric containers are the same height, and are closed by the same cover. Such a design makes it difficult to mix the different compositions it contains.

La demande de brevet FR-A-2 658 484 décrit un dispositif pour le mélange extemporané de deux compositions, selon le préambule de la revendication 1. Un tel dispositif, de par sa forme, n'est pas adapté au mélange de compositions dont l'une au moins est de viscosité importante. En effet, sa forme ne permet pas facilement, l'homogénéisation du mélange au moyen d'un outil approprié.Patent application FR-A-2 658 484 describes a device for mixing extemporaneous of two compositions, according to the preamble of claim 1. Such a device, by its shape, is not suitable for mixing compositions of which at least one is of viscosity important. Indeed, its shape does not allow easily, the homogenization of the mixing using a suitable tool.

Aussi, c'est avec étonnement que la demanderesse a découvert un récipient peu coûteux, pour le conditionnement séparé d'au moins un produit de base et d'au moins un produit secondaire, en un seul corps et qui peut être fabriqué dans des conditions économiques intéressantes. Ce récipient permet en particulier le stockage et le mélange dans de bonnes conditions de produits s'écoulant mal, notamment de plusieurs produits dont l'un au moins est visqueux, comme par exemple deux crèmes ou une poudre avec une crème ou une pâte.Also, it was with astonishment that the plaintiff discovered a little container expensive, for separate packaging of at least one basic product and of minus a secondary product, in one body and which can be manufactured in attractive economic conditions. This container allows in particular the storage and mixing under good conditions of poorly flowing products, in particular of several products of which at least one is viscous, such as by example two creams or a powder with a cream or a paste.

L'invention a pour objet un récipient pour le conditionnement séparé et le mélange d'au moins un produit de base et d'au moins un produit secondaire, comprenant un corps, un bouchon interne, un moyen de fermeture et un dispositif d'ouverture du bouchon interne, le corps comprenant une paroi définissant le profil d'une cavité principale susceptible de contenir le produit de base et le profil d'une cavité secondaire susceptible de contenir le produit secondaire, la cavité secondaire se trouvant incluse dans la cavité principale, le bouchon interne permettant d'isoler hermétiquement la cavité secondaire de la cavité principale, le moyen de fermeture permettant d'isoler hermétiquement la cavité principale de l'air extérieur, le dispositif d'ouverture du bouchon interne permettant d'ôter le bouchon interne avant ou simultanément à l'ouverture de la cavité principale, la mise en contact du produit de base avec le produit secondaire, en vue de leur mélange, se faisant lors de l'enlèvement du bouchon interne, caractérisé en ce que la cavité principale est globalement en forme de bol.The subject of the invention is a container for separate packaging. and the mixture of at least one basic product and at least one secondary product, comprising a body, an internal plug, a closure means and a device opening the internal plug, the body comprising a wall defining the profile of a main cavity likely to contain the basic product and the profile a secondary cavity likely to contain the secondary product, the cavity secondary being included in the main cavity, the internal plug allowing to hermetically isolate the secondary cavity from the main cavity, the closing means making it possible to hermetically isolate the main cavity from outside air, the internal cap opening device allowing the internal plug before or simultaneously with the opening of the main cavity, the bringing the basic product into contact with the secondary product, with a view to their mixing, taking place during removal of the internal plug, characterized in that the main cavity is generally in the form of a bowl.

Ce dispositif permet d'éviter des manipulations risquées au moment de l'ouverture de la cavité secondaire, puisque celle-ci se fait alors que la cavité principale est encore fermée et que le contenu des deux cavités ne peut donc pas se répandre à l'extérieur, ou simultanément à l'ouverture de la cavité principale et l'utilisateur n'a pas à manipuler le bouchon de la cavité secondaire tandis que la cavité principale est déjà ouverte et que son contenu pourrait s'en échapper.This device avoids risky handling when the opening of the secondary cavity, since this is done while the cavity main is still closed and therefore the contents of the two cavities cannot not spread outside, or simultaneously with the opening of the cavity primary and the user does not have to handle the plug of the secondary cavity while the main cavity is already open and its contents could be escape.

Le profil de la cavité principale a globalement la forme d'un bol. Dans cette forme peut venir s'inscrire le profil de la cavité secondaire sous la forme d'une excroissance. Le profil de la cavité principale peut également être muni d'un fond plat.The profile of the main cavity is generally in the form of a bowl. In this form can come to register the profile of the secondary cavity in the form of a outgrowth. The profile of the main cavity can also be provided with a bottom dish.

La forme de bol permet en particulier un mélange facile des produits contenus dans le corps, à l'aide d'instruments, comme par exemple un pinceau ou un bâton. Cette facilité est extrêmement favorable à l'obtention d'un mélange homogène à partir de produits s'écoulant mal, en particulier de produits dont l'un au moins est visqueux. Cette facilité de mélange est d'autant plus importante lorsque l'utilisateur de ces produits n'est pas un homme du métier mais un consommateur courant.The bowl shape allows in particular an easy mixing of the contained products in the body, using instruments, such as a paintbrush or a stick. This facility is extremely favorable for obtaining a mixture homogeneous from poorly flowing products, in particular products one of which at least is viscous. This ease of mixing is all the more important when the user of these products is not a person skilled in the art but a current consumer.

Le corps est en matériau thermoplastique. Il peut résulter de la superposition de plusieurs matériaux thermoplastiques différents et il peut être fabriqué par tous moyens connus de l'homme du métier comme, par exemple, le thermoformage, l'injection, le soufflage. De façon préférentielle, afin de rendre le produit économiquement intéressant, il est fabriqué par thermoformage ou par injection, et selon un mode préféré de réalisation de l'invention, il est fabriqué par thermoformage.The body is made of thermoplastic material. It can result from the superposition of several different thermoplastic materials and it can be manufactured by all means known to those skilled in the art such as, for example, thermoforming, injection, blowing. Preferably, in order to make the product economically attractive, it is manufactured by thermoforming or by injection, and according to a preferred embodiment of the invention, it is manufactured by thermoforming.

Comme matériau thermoplastique on peut utiliser par exemple du polyéthylène, du polypropylène, un copolymère de l'éthylène et du propylèneAs a thermoplastic material, polyethylene can be used, for example, polypropylene, a copolymer of ethylene and propylene

Le moyen de fermeture peut être un bouchon externe placé à l'ouverture de la cavité principale; dans ce cas le corps comprend des moyens d'accrochage complémentaires à la périphérie de la cavité principale. Le moyen de fermeture peut également être une pellicule arrachable d'un seul tenant.The closure means may be an external plug placed at the opening of the main cavity; in this case the body comprises attachment means complementary to the periphery of the main cavity. The means of closure can also be a single-piece peel-off film.

Dans le cas où le moyen de fermeture est une pellicule arrachable d'un seul tenant, celle-ci est en matériau étanche à l'air et compatible chimiquement avec les produits de base et secondaire. La pellicule est fixée à la paroi du corps et placée à l'ouverture de la cavité principale. La fixation de la pellicule au corps doit être à la fois étanche et arrachable manuellement. En outre, il faut que la pellicule soit dans un matériau tel qu'elle ne se déchire pas lorsqu'elle est arrachée du corps, mais au contraire s'enlève d'un seul tenant. Une telle pellicule est habituellement constituée d'au moins trois couches superposées : la couche du milieu, qui peut être en aluminium ou en matériau thermoplastique, détermine l'étanchéité de la pellicule, la couche supérieure en matériau thermoplastique conditionne la non-déchirabilité de la pellicule et la couche inférieure est un film thermoplastique qui rend la pellicule pelable.In the case where the closure means is a tear-off film of a single holding, it is made of airtight material and chemically compatible with basic and secondary products. The film is attached to the wall of the body and placed at the opening of the main cavity. Fixing the film to the body must be both waterproof and manually removable. In addition, the film is in a material such that it does not tear when it is torn from the body, but on the contrary is removed in one piece. Such film usually consists of at least three superimposed layers: the layer medium, which can be aluminum or thermoplastic material, determines waterproofing of the film, the upper layer of thermoplastic material conditions the non-tearability of the film and the lower layer is a film thermoplastic which makes the film peelable.

Le bouchon interne est essentiellement constitué d'une jupe et d'un fond, il doit permettre la fermeture étanche de la cavité secondaire, il doit aussi pouvoir être ôté facilement avant, ou simultanément à, l'ouverture de la cavité principale, pour permettre le mélange des deux produits avant utilisation. La cavité secondaire est munie, à ses extrémités, de moyens d'accrochage qui coopèrent avec la jupe du bouchon et permettent sa fixation étanche. The internal cap consists essentially of a skirt and a bottom, it must allow the watertight closing of the secondary cavity, it must also be able to be easily removed before, or simultaneously with, the opening of the main cavity, to allow the two products to be mixed before use. The secondary cavity is provided, at its ends, with hooking means which cooperate with the skirt of the plug and allow its watertight fixing.

Le bouchon interne est de préférence en matériau thermoplastique, il pourra être fabriqué par tous moyens connus de l'homme du métier, comme par exemple par thermoformage d'un film extrudé ou par injection. De façon préférentielle, le bouchon sera fabriqué par injection, cette technique, plus précise, permet de faciliter l'obtention d'une meilleure étanchéité.The internal plug is preferably made of thermoplastic material, it can be manufactured by any means known to those skilled in the art, such as for example by thermoforming of an extruded film or by injection. Preferably, the cap will be manufactured by injection, this more precise technique allows facilitate obtaining a better seal.

Afin de permettre à l'utilisateur d'ôter le bouchon, plusieurs solutions peuvent être envisagées :In order to allow the user to remove the cap, several solutions can be considered:

Dans une première variante, le profil de la cavité secondaire comprend un doigt rigide et une zone déformable à la périphérie et à une première extrémité de ce doigt, ce doigt et cette zone déformable coopérant de telle sorte qu'une pression exercée sur la zone déformable fasse sauter le bouchon interne par appui de son autre extrémité sur ledit bouchon interne. Ce geste doit de préférence être fait avant d'avoir retiré la pellicule. la périphérie de ce doigt peut être rendue déformable par tous moyens connus de l'homme du métier comme par exemple par la présence de gorges dans le profil de la cavité ou par une moindre épaisseur du matériau thermoplastique à la périphérie de ce doigt. Eventuellement le bouchon interne peut être muni d'une jupe interne dans laquelle vient se placer le doigt rigide et qui l'empêche de fléchir sous la pression.In a first variant, the profile of the secondary cavity comprises a finger rigid and a deformable zone at the periphery and at a first end of this finger, this finger and this deformable zone cooperating so that a pressure exerted on the deformable zone causes the internal plug to pop by pressing its other end on said internal plug. This gesture should preferably be made before removing the film. the periphery of this finger can be made deformable by any means known to those skilled in the art, for example by the presence of grooves in the profile of the cavity or by a lesser thickness of the thermoplastic material at the periphery of this finger. Optionally the internal plug may be provided with an internal skirt in which is placed the rigid finger and which prevents it from bending under the pressure.

Dans une seconde variante, le bouchon interne comprend une tige rigide dont l'extrémité repose sur la parois de la cavité secondaire. Une pression exercée sur cette parois permet de faire sauter le bouchon. Ce geste doit également être fait avant d'avoir enlevé la pellicule.In a second variant, the internal plug comprises a rigid rod whose the end rests on the walls of the secondary cavity. Pressure on this wall makes it possible to blow up the plug. This gesture must also be made before removing the film.

Dans une troisième variante, le bouchon interne est muni d'une languette scellée comprenant deux extrémités, une extrémité fixée au bouchon interne, et une autre extrémité scellée au moyen de fermeture, au moyen d'un scellage non arrachable, en particulier lorsque le moyen de fermeture est une pellicule arrachable le scellage de la languette sur la pellicule est différent du scellage de la pellicule sur le corps, ainsi, lorsque l'utilisateur enlève la pellicule, celle-ci entraíne avec elle la languette et le bouchon interne. Cette solution présente l'avantage de permettre en un seul geste l'ouverture des deux cavité et l'entraínement du bouchon interne hors du récipient.In a third variant, the internal plug is provided with a sealed tongue comprising two ends, one end fixed to the internal plug, and one other end sealed by means of closure, by means of non-sealing peelable, especially when the closure is a film tear-off sealing of the tab on the film is different from sealing of the film on the body, so when the user removes the film, it brings with it the tongue and the internal plug. This solution presents the advantage of allowing in one gesture the opening of the two cavities and driving the internal plug out of the container.

Selon une quatrième variante, le bouchon interne comprend une jupe creuse d'une hauteur suffisante pour que le fond émerge de la cavité principale au niveau de la parois supérieure du corps et le fond du bouchon interne est scellé au moyen de fermeture . Selon l'invention, le scellage du fond du bouchon interne au moyen de fermeture n'est pas arrachable, en particulier lorsque le moyen de fermeture est une pellicule arrachable le scellage du bouchon interne sur la pellicule est différent du scellage de la pellicule sur le corps, ainsi, lorsque l'utilisateur enlève la pellicule, celle-ci entraíne avec elle le bouchon interne. Cette solution présente l'avantage de permettre en un seul geste l'ouverture des deux cavité et l'entraínement du bouchon interne hors du récipient.According to a fourth variant, the internal plug comprises a hollow skirt of sufficient height for the bottom to emerge from the main cavity at level of the upper body walls and the bottom of the inner cap is sealed by means of closure. According to the invention, the sealing of the bottom of the cap internal by the closing means is not removable, in particular when the closure means is a tear-off film sealing the inner cap on the film is different from sealing the film on the body, so when the user removes the film, it drives with it the internal plug. This solution has the advantage of allowing the opening of two cavity and the internal plug drive out of the container.

Selon les trois premières variantes de l'invention le fabriquant remplit tout d'abord la cavité secondaire avec le produit secondaire puis il obture cette cavité par le bouchon interne, il remplit ensuite la cavité principale et l'obture, éventuellement en scellant la languette à la pellicule dans le cas de la troisième variante.According to the first three variants of the invention, the manufacturer fills all first the secondary cavity with the secondary product then it closes this cavity by the internal plug, it then fills the main cavity and closes it, possibly by sealing the tab to the film in the case of the third variant.

Selon la quatrième variante le fabriquant peut, suivant la forme de la cavité, procéder comme selon les variantes précédentes, il peut également placer le produit secondaire à l'intérieur du bouchon interne creux, ledit bouchon étant retourné pour reposer sur son fond. Il fixe ensuite le corps sur ce bouchon, puis il retourne l'ensemble et remplit la cavité principale puis fixe le moyen de fermeture, en scellant le fond du bouchon interne sur la pellicule.According to the fourth variant, the manufacturer can, depending on the shape of the cavity, proceed as according to the previous variants, it can also place the secondary product inside the hollow internal plug, said plug being turned over to rest on its bottom. He then fixes the body on this plug, then he returns the assembly and fills the main cavity then fixes the means of closing, sealing the bottom of the inner cap on the film.

Selon le cas, le profil du corps peut être muni d'un fond plat qui lui permet de reposer sur une surface plane, ce corps peut également comprendre une jupe qui lui permet de reposer sur une surface plane quel que soit le profil du reste du corps. Depending on the case, the body profile can be provided with a flat bottom which allows it to rest on a flat surface, this body may also include a skirt which allows it to rest on a flat surface regardless of the profile of the rest of the body.

Après avoir enlevé la pellicule et ouvert la cavité secondaire, l'utilisateur peut mélanger à l'aide de tout instrument connu, comme un pinceau ou un bâton, le produit de base et le produit secondaire.After removing the film and opening the secondary cavity, the user can mix using any known instrument, such as a brush or stick, the basic product and secondary product.

Le récipient selon l'invention peut comprendre en outre une cavité échantillon ménagée dans la parois du corps, cette cavité étant susceptible de contenir une dose d'échantillon du produit de base ou du produit secondaire. Cette cavité est obturée par un moyen de fermeture du même type que celui qui obture la cavité principale. Toutefois ces deux moyens sont distincts, ce qui permet d'ouvrir la cavité échantillon et de doser le produit qu'elle contient sans ouvrir la cavité principale.The container according to the invention can also comprise a sample cavity formed in the walls of the body, this cavity being capable of containing a sample dose of the primary or secondary product. This cavity is closed by a closure means of the same type as that which closes the cavity main. However, these two means are distinct, which makes it possible to open the sample cavity and measure the product it contains without opening the cavity main.

Le récipient selon l'invention peut comprendre en outre une cavité instruments ménagée dans la parois du corps, cette cavité étant susceptible de contenir divers instruments utiles pour la manipulation des produits, comme par exemple des gants, un pinceau etc....De la même façon que la cavité échantillon, la cavité instruments peut être obturée par un moyen de fermeture indépendant, elle peut toutefois être obturée par le même moyen de fermeture que la cavité principale.The container according to the invention may further comprise an instrument cavity formed in the walls of the body, this cavity being capable of containing various instruments useful for handling products, such as for example gloves, a brush etc ... In the same way as the sample cavity, the cavity instruments can be closed by an independent closing means, it can however, be closed by the same closing means as the main cavity.

Afin de mieux faire comprendre l'objet de l'invention, on va décrire ci-après, à titre d'exemple non limitatif, des récipients répondant aux caractéristiques de cette invention.

  • Figures 5 and 6 each show a device according to the invention in cross section, these devices each comprising an emerging plug, provided with a rigid rod, sealed by means of closing the main cavity.

    • Le récipient représenté sur la figure 1 est constitué d'un corps 1 en polyéthylène thermoformé, d'un bouchon interne 2, de deux pellicules thermoscellées 3 et 4. Le corps 1 a la forme d'un mamelon qui définit une cavité principale 1.1 en forme de bol et une cavité secondaire 2.1 dans le fond de la cavité principale 1.1 ; des moyens d'accrochage 1.5 du type encliquettage permettent une fixation étanche du bouchon 2 qui sépare la cavité 1.1, contenant un produit 1.2, et la cavité 2.1 contenant un produit 2.2. Les produits 1.2 et 2.2 sont respectivement une crème et une poudre pour la coloration des cheveux. Une jupe circulaire 1.6 périphérique permet de poser le récipient sur une surface plane. A cet effet la jupe 1.6 a une hauteur au moins égale à celle du mamelon. En outre la paroi du corps 1 comprend au niveau de la cavité 2.1 un doigt 2.3 et une gorge annulaire 2.3.1 autour de ce doigt. L'extrémité supérieure de ce doigt est placée dans une jupe 2.3.2 du bouchon 2 s'étendant dans la cavité secondaire. La gorge annulaire 2.3.1 rend déformable la zone 2.3.3, à la périphérie du doigt. On peut exercer sur cette zone à la base du doigt 2.3 une pression P pour faire sauter le bouchon 2. Les cavités annexes 1.3 et 1.4 permettent le stockage respectivement de divers ustensiles, et d'un échantillon du produit 2.2. La cavité 1.4 est obturée par la pellicule 4, indépendante de la pellicule 3. Cette dernière obture à la fois la cavité principale 1.1 et la cavité annexe 1.3.
    Dans un premier temps l'utilisateur arrache la pellicule 4 et utilise l'échantillon contenu dans 1.4 pour tester la tolérance de ce produit sur sa peau, puis il retourne le récipient et exerce une pression sur la zone déformable 2.3.3 à la base du doigt 2.3 ôtant ainsi le bouchon 2. Il retourne à nouveau le récipient et arrache la pellicule 3, les ustensiles contenus dans 1.3 sont alors accessibles et il peut mélanger les produits 1.2 et 2.2.     The container shown in Figure 1 consists of a body 1 of thermoformed polyethylene, an internal cap 2, two heat-sealed films 3 and 4. The body 1 has the shape of a nipple which defines a main cavity 1.1 in bowl shape and a secondary cavity 2.1 in the bottom of the main cavity 1.1; hooking means 1.5 of the snap-on type allow a tight fixing of the plug 2 which separates the cavity 1.1, containing a product 1.2, and the cavity 2.1 containing a product 2.2. Products 1.2 and 2.2 are respectively a cream and a powder for coloring hair. A peripheral circular skirt 1.6 allows the container to be placed on a flat surface. For this purpose the skirt 1.6 has a height at least equal to that of the nipple. In addition, the wall of the body 1 comprises, at the level of the cavity 2.1, a finger 2.3 and an annular groove 2.3.1 around this finger. The upper end of this finger is placed in a skirt 2.3.2 of the plug 2 extending in the secondary cavity. The 2.3.1 annular groove makes zone 2.3.3 deformable, at the periphery of the finger. One can exert on this zone at the base of the finger 2.3 a pressure P to blow up the plug 2. The annex cavities 1.3 and 1.4 allow the storage respectively of various utensils, and of a sample of the product 2.2. The cavity 1.4 is closed by the film 4, independent of the film 3. The latter closes both the main cavity 1.1 and the annex cavity 1.3.
    At first the user tears off the film 4 and uses the sample contained in 1.4 to test the tolerance of this product on his skin, then he returns the container and exerts a pressure on the deformable zone 2.3.3 at the base of the finger 2.3 thus removing the cap 2. He again turns the container over and tears off the film 3, the utensils contained in 1.3 are then accessible and he can mix the products 1.2 and 2.2.

    Le récipient représenté sur les figures 2a et 2b se différencie de celui de la figure 1 par l'absence de doigt dans la cavité secondaire et par l'existence d'une tige rigide 2.4 fixée au bouchon interne 2 et dont l'extrémité est en regard de la paroi de la cavité 2.1. Le mode d'utilisation illustré par la figure 2b est le même que sur la figure 1. La zone déformable est faite d'une épaisseur plus mince de la paroi du corps 1 située en regard de l'extrémité de la tige 1.4.The container shown in Figures 2a and 2b differs from that in Figure 1 by the absence of a finger in the secondary cavity and by the existence of a rod rigid 2.4 fixed to the internal plug 2 and the end of which faces the wall of the cavity 2.1. The mode of use illustrated in FIG. 2b is the same as on Figure 1. The deformable area is made of a thinner wall thickness of the body 1 located opposite the end of the rod 1.4.

    Le récipient représenté sur la figure 3 se différencie de celui de la figure 1 par l'absence de doigt dans la cavité secondaire, par l'existence d'une languette scellée 2.6. La languette 2.6 comprend deux extrémités, l'une de ces extrémités étant fixée au bouchon interne 2 et l'autre étant scellée à la pellicule 3. Après ouverture de la pellicule 4 permettant d'avoir accès à l'échantillon, l'utilisateur arrache la pellicule 3 il entraíne également la languette 2.6 ainsi que le bouchon interne 2, il peut ensuite mélanger les produits à l'aide des ustensiles extraits de la cavité 1.3.The container shown in Figure 3 differs from that of Figure 1 by the absence of a finger in the secondary cavity, by the existence of a tongue sealed 2.6. Tab 2.6 has two ends, one of these ends being attached to the inner cap 2 and the other being sealed with film 3. After opening of the film 4 allowing access to the sample, the user tears off the film 3 it also drives the tab 2.6 as well as the plug internal 2, he can then mix the products using utensils extracted from the cavity 1.3.

    Le dispositif représenté sur les figures 4a, 4b et 4c est constitué d'un corps 1, d'un bouchon interne 2, et de 2 pellicules 3 et 4. Ce dispositif se distingue de celui de la figure 1 par le fait que le bouchon interne 2 comporte une jupe cylindrique d'une hauteur telle que le fond du bouchon affleure à la surface de la cavité principale 1.1 qui a la forme d'un bol. Le fond du bouchon 2 est scellé à la pellicule 3 obturant la cavité principale de telle sorte que lorsque l'on arrache la pellicule, le bouchon qui en est solidaire s'ouvre et libère le produit secondaire 2.2 qu'il retenait dans la cavité 2.1. Comme il est montré sur la figure 4c, lors du conditionnement, on remplit le bouchon 2 de produit 2.2 puis on positionne le corps sur le bouchon de façon étanche, et ensuite seulement on retourne le corps et on remplit la cavité principale avec le produit 1.2.The device represented in FIGS. 4a, 4b and 4c consists of a body 1, an internal cap 2, and 2 films 3 and 4. This device is distinguished from that of FIG. 1 by the fact that the internal plug 2 comprises a skirt cylindrical of a height such that the bottom of the plug is flush with the surface of the main cavity 1.1 which has the shape of a bowl. The bottom of the plug 2 is sealed with the film 3 closing the main cavity so that when the film, the plug attached to it opens and releases the secondary product 2.2 which it retained in the cavity 2.1. As shown in Figure 4c, when packaging, fill the cap 2 with product 2.2 and then position the body on the cap tightly, and only then we turn the body and fill the main cavity with the product 1.2.

    Le dispositif représenté sur la figure 5 se distingue de celui représenté sur les figures 4a et 4b par la présence d'une tige rigide 2.4 fixée au bouchon interne 2 et dont l'extrémité est en regard de la parois de la cavité 2.1. Dans un premier temps, l'utilisateur décroche le bouchon 2 en exerçant une pression sur la zone déformable 2.3.3, puis il ôte la pellicule 3 qui entraíne avec elle le bouchon 2 hors du récipient. Ce dispositif présente l'avantage par rapport au précédent d'éviter des projections lors de l'ouverture du bouchon 2.The device shown in Figure 5 differs from that shown in the Figures 4a and 4b by the presence of a rigid rod 2.4 fixed to the internal plug 2 and the end of which faces the walls of the cavity 2.1. Initially time, the user unhooks the plug 2 by exerting pressure on the area deformable 2.3.3, then it removes the film 3 which carries with it the plug 2 out of the container. This device has the advantage compared to the previous one avoid splashing when opening the cap 2.

    Le dispositif représenté sur la figure 6 se distingue de celui de la figure 5 par le fait que le fond 2.8 du bouchon est placé plus bas. Le bouchon 2 adhère à la pellicule 3 par sa jupe 2.9. Le fonctionnement est le même que celui décrit pour la figure 5. Ce dispositif présente l'avantage, par rapport au précédent, d'éviter qu'une partie du produit 2.2 ne reste collée aux parois du bouchon 2.The device shown in Figure 6 differs from that of Figure 5 by the causes the bottom 2.8 of the plug to be placed lower. The cap 2 adheres to the film 3 by its skirt 2.9. The operation is the same as that described for Figure 5. This device has the advantage, compared to the previous one, of avoiding that part of the product 2.2 remains stuck to the walls of the plug 2.
