An independent claim is also included for an assembly including two product distributing devices.

Description

La présente invention a trait à un pot distributeur pour le conditionnement et la distribution de produits de consistance visqueuse, notamment sous forme d'une crème, d'une pâte, d'une pommade, d'un baume ou d'un gel. L'invention est tout particulièrement adaptée au conditionnement et à la distribution de produits à usage cosmétique, dermatologique ou médical, tels que des crèmes de soin. L'invention vise en particulier la distribution facilitée du contenu de tels pots.The present invention relates to a dispensing pot for packaging and the distribution of products with a viscous consistency, in particular in the form of cream, paste, ointment, balm or gel. The invention is everything particularly suitable for the packaging and distribution of products cosmetic, dermatological or medical use, such as skincare creams. The invention aims in particular the facilitated distribution of the contents of such pots.

Dans le domaine de la cosmétique et du soin de la peau, le pot a été, et continue d'être, largement utilisé. Le pot est particulièrement adapté au conditionnement de ces produits dans la mesure où il permet un accès facile au produit qu'il contient, notamment quand il s'agit de prélever le produit directement avec les doigts. En outre, de par la large ouverture qui le caractérise, il est possible de le vidanger de manière complète, ce qui est tout particulièrement souhaitable pour des produits dont le prix de vente à la consommatrice, relativement au poids, est élevé.In the field of cosmetics and skincare, the pot has been, and continues to be, widely used. The pot is particularly suitable for packaging of these products to the extent that it allows easy access to product it contains, especially when it comes to taking the product directly with the fingers. Moreover, because of the broad opening that characterizes it, it is possible to completely drain it, which is especially desirable for products whose selling price to the consumer, relative to the weight, is high.

Un des problèmes qui se pose avec un tel mode de conditionnement et de distribution tient à la protection de son contenu, notamment par rapport à l'air ambiant, au contact duquel, ce type de produit est susceptible de se détériorer. Un autre problème tient à la "contamination" du produit que peut générer un tel mode de prélèvement avec les doigts. Pour résoudre ce dernier problème, il a été proposé de prélever le produit au moyen d'une spatule. Ce mode de prélèvement n'a cependant aucune fonction de protection du contenu au regard des contaminations de la spatule par les doigts ou du contact avec l'air.One of the problems that arises with such a mode of conditioning and Distribution is concerned with the protection of its contents, particularly with respect to air ambient, in contact with which, this type of product is likely to deteriorate. A Another problem is the "contamination" of the product that can generate such a mode sampling with the fingers. To solve this last problem, it has been proposed to take the product by means of a spatula. This method of sampling however, has no function of protecting the content with regard to contaminations of the spatula by the fingers or contact with the air.

Il est connu également de protéger le produit au moyen d'un disque qui recouvre la surface libre du produit, lequel disque est muni d'une ou plusieurs ouvertures disposées dans un plan parallèle au plan du disque, c'est à dire sensiblement perpendiculaire à l'axe du pot. De manière générale, la distribution du produit est obtenue en enfonçant le disque à l'intérieur du pot, soit par simple coulissement selon l'exemple du document GB-A-1 050 984, soit par mise en rotation, notamment via un pas de vis formé sur la paroi intérieure du pot, et apte à coopérer avec un filetage correspondant formé à la périphérie du disque, selon l'exemple du document DE-A-37 26 729. De la surpression exercée à l'intérieur du pot, il résulte un mouvement de fluage du produit, et une sortie de ce dernier au travers de la ou des ouverture(s) du disque.It is also known to protect the product by means of a disc which covers the free surface of the product, which disc is equipped with one or more openings arranged in a plane parallel to the plane of the disk, ie substantially perpendicular to the axis of the pot. In general, the distribution of the product is obtained by pressing the disc inside the pot, either by simple sliding according to the example of GB-A-1 050 984, either by setting rotation, in particular via a screw thread formed on the inner wall of the pot, and adapted to cooperate with a corresponding thread formed at the periphery of the disk, according to the example of document DE-A-37 26 729. The overpressure exerted inside the pot, it results in a creep movement of the product, and an output of the latter at through the opening (s) of the disc.

Le disque est impérativement déplacé strictement parallèlement à l'axe de symétrie de révolution du pot pour ne pas avoir de fuite de produit à la jonction entre le pourtour du disque et les parois intérieures cylindriques du pot. Au fur et à mesure des prélèvements de produit, le disque est progressivement entraíné vers le fond du pot. Le prélèvement du produit sur l'opercule au fond du réservoir est de moins en moins aisé au fur et à mesure des utilisations.The disc is imperatively moved strictly parallel to the axis of symmetry of revolution of the pot for not having product leak at the junction between the periphery of the disc and the cylindrical inner walls of the pot. As and when measurement of the product samples, the disc is progressively driven towards the bottom of the pot. The sampling of the product on the lid at the bottom of the tank is less and less easy as and when used.

De ce fait il existe dans l'état de la technique des pots pour lesquels le disque reste à hauteur fixe relativement au fond du pot, mais pour lesquels le disque reste libre en rotation dans une rainure du pot. Pour permettre la sortie de produit, le disque est alors muni, comme dans l'exemple décrit par le document DE-A-31 00 529, d'une paroi s'étendant dans le pot de manière à coopérer avec un panneau fixe du pot de manière à définir une chambre de volume intérieur variable en fonction du déplacement de cette paroi relativement au panneau fixe. Le produit contenu dans cette chambre peut ainsi être comprimé par le rapprochement de la paroi relativement au panneau fixe. Ce déplacement de la paroi est obtenu par la rotation du disque autour d'un axe de rotation formé par un axe de symétrie de révolution du pot.As a result, there are pots in the state of the art for which the disc remains fixed height relative to the bottom of the pot, but for which the disc remains free in rotation in a groove of the pot. To allow the release of produced, the disk is then provided, as in the example described by the document DE-A-31 00 529, a wall extending in the pot so as to cooperate with a fixed panel of the pot so as to define an interior volume chamber variable depending on the displacement of this wall relative to the fixed panel. The product contained in this chamber can thus be compressed by the approach of the wall relative to the fixed panel. This displacement of the wall is obtained by rotating the disk about an axis of rotation formed by a axis of symmetry of revolution of the pot.

Le produit est alors comprimé de manière à être distribué au niveau d'une face supérieure du disque, selon un flux parallèle à cet axe de rotation. En particulier, le produit flue à l'intérieur du pot selon deux directions orthogonales, une première direction est donnée dans un plan orthogonal à l'axe de rotation, du fait même de cette rotation de la paroi relativement au panneau fixe, et une seconde direction est donnée par la position de l'orifice de sortie dans le disque. Le produit est donc soumis à des flux dont les différentes directions peuvent altérer sa structure chimique.The product is then compressed to be distributed at a upper face of the disc, according to a flow parallel to this axis of rotation. In in particular, the product flows inside the pot in two orthogonal directions, a first direction is given in a plane orthogonal to the axis of rotation, from even this rotation of the wall relative to the fixed panel, and a second direction is given by the position of the outlet orifice in the disc. The product is therefore subject to flows whose different directions can alter its chemical structure.

Le document US-B-6,422,424 décrit une variante du pot selon le document DE-31 00 529 dans la mesure où le disque comporte deux parois s'étendant orthogonalement au disque à l'intérieur du pot, de manière à coopérer chacune avec un panneau fixe distinct à l'intérieur du pot. Ainsi le pot peut permettre la distribution de deux produits chacun isolément contenu dans une chambre définie entre l'une des parois et l'un des panneaux fixes. Ces deux produits sortent respectivement par deux orifices du disque. Ces orifices sont diamétralement opposés, de manière à être chacun disposés dans une partie du secteur angulaire de l'opercule la plus longuement en communication avec la chambre définie en dessous de ce secteur angulaire. Un tel pot n'offre pas la possibilité de conditionner séparément deux produits et de permettre ensuite leur distribution simultanée au niveau d'un seul et même orifice.Document US-B-6,422,424 describes a variant of the pot according to the document DE-31 00 529 insofar as the disc has two walls extending orthogonally to the disk inside the pot, so as to cooperate with each with a separate fixed panel inside the pot. So the pot can allow the distribution of two products each singly contained in a defined chamber between one of the walls and one of the fixed panels. These two products are coming out respectively by two holes of the disc. These holes are diametrically opposite, so as to be each arranged in a part of the angular sector operculum for the longest time in communication with the chamber defined in below this angular sector. Such a pot does not offer the possibility of condition two products separately and then allow their distribution simultaneously at one and the same orifice.

On connaít aussi dans l'état de la technique, du document FR-852,719, un boítier rigide pour distribuer sous pression un produit pâteux.Also known in the state of the art, the document FR-852,719, a rigid housing for dispensing under pressure a pasty product.

Dans l'état de la technique il existe un besoin pour des pots de forme alternative, muni d'un système de distribution hygiénique et facile à réaliser, comportant un minimum de pièces de manière à minimiser leurs coûts de réalisation. De plus, il existe également un besoin d'une gestuelle de distribution différente de la gestuelle à mettre en oeuvre pour manipuler les différents pots de l'état de la technique. Il existe aussi un besoin pour que cette nouvelle gestuelle de manipulation n'altère pas la structure physico-chimique parfois instable du produit.In the state of the art there is a need for jars of form alternative, equipped with a hygienic dispensing system and easy to perform, minimum parts to minimize their cost of ownership. production. In addition, there is also a need for a distribution gesture different from the gestures to be used to manipulate the different pots of the state of the art. There is also a need for this new gesture manipulation does not alter the sometimes unstable physico-chemical structure of the product.

L'invention se propose de résoudre au moins l'un des problèmes identifiés ci-dessus en proposant un dispositif de conditionnement et de distribution d'un produit cosmétique, notamment de maquillage et/ou de soin, comportant un récipient formant au moins un logement apte à recevoir le produit, ledit logement comportant une première paroi définissant au moins en partie une surface intérieure dudit logement, et une deuxième paroi mobile en rotation relativement à la première paroi autour d'un axe de rotation, le déplacement en rotation de la deuxième paroi autour dudit axe permettant une diminution d'un écart angulaire défini entre ces deux parois,

  • la deuxième paroi présentant un bord périphérique dont au moins une portion est en engagement étanche avec la surface intérieure lors de son déplacement en rotation autour dudit axe, et
  • la deuxième paroi délimitant au moins un orifice de sortie pour permettre, en réponse à la diminution de l'écart angulaire, une distribution du produit selon un flux de direction distincte de celle de l'axe de rotation.
The invention proposes to solve at least one of the problems identified above by proposing a device for packaging and dispensing a cosmetic product, especially a make-up and / or care product, comprising a container forming at least one housing adapted to receive the product, said housing having a first wall defining at least partly an inner surface of said housing, and a second wall movable in rotation relative to the first wall about an axis of rotation, the rotational displacement of the second wall around said axis allowing a decrease of an angular difference defined between these two walls,
  • the second wall having a peripheral edge of which at least a portion is in sealing engagement with the inner surface as it rotates about said axis, and
  • the second wall defining at least one outlet to allow, in response to the decrease of the angular difference, a distribution of the product according to a flow of direction distinct from that of the axis of rotation.

De préférence, le récipient est conçu de telle sorte que lorsqu'il repose de manière stable sur une surface, la manipulation de la deuxième paroi et le prélèvement du produit peuvent être réalisés d'une seule main.Preferably, the container is designed so that when it rests stably on a surface, the manipulation of the second wall and the Product picking can be done with one hand.

Avantageusement, les deux parois comportent respectivement deux faces aptes à être accolées en tout point lorsque l'écart angulaire est minimal, de manière à optimiser la vidange du récipient.Advantageously, the two walls respectively comprise two faces able to be contiguous at any point when the angular difference is minimal, of to optimize emptying the container.

Par ailleurs du fait que le produit est contenu dans ledit logement, le produit n'est de préférence plus accessible que par l'orifice de sortie, ce qui permet de limiter les risques de pollution du produit. Lors de la mise en rotation de la deuxième paroi relativement à la première paroi, le produit est comprimé dans le logement de manière à fluer au travers de cet orifice de sortie pour être distribué hors du dispositif.Moreover, since the product is contained in said housing, the product is preferably accessible only through the outlet, which allows to limit the risks of pollution of the product. When rotating the second wall relative to the first wall, the product is compressed in the housing so as to flow through this outlet to be dispensed out of the device.

Par exemple, l'orifice de sortie est défini au travers de la deuxième paroi à distance des bordures de cette paroi. En variante, il peut être débouchant au niveau d'une bordure libre de la deuxième paroi.For example, the outlet orifice is defined through the second wall to distance from the borders of this wall. Alternatively, it can be level of a free edge of the second wall.

En particulier, si l'on considère une ouverture du logement délimitée par des chants de parois délimitant ledit logement, un chant de la première paroi délimitant par exemple en partie cette ouverture, alors la deuxième paroi est apte à obturer au moins partiellement cette ouverture.In particular, if we consider an opening of the dwelling delimited by wall edges delimiting said housing, a song of the first wall delimiting for example in part this opening, then the second wall is fit to at least partially close this opening.

Avantageusement, la surface intérieure peut être définie au moins en partie par une surface continue formée d'une pluralité d'arcs de cercle parallèles entre eux dont les centres respectifs appartiennent à l'axe de rotation. Par exemple, ces arcs de cercle peuvent être identiques entre eux, et superposables les uns aux autres, de manière à définir avec la première paroi un volume délimitant une portion de cylindre. Dans ce cas, les deux parois du logement peuvent respectivement être définies par des surfaces continues formées d'une pluralité de liaisons entre au moins un point de chacun de ces arcs de cercle et l'axe de rotation. En particulier, au moins l'une des deux parois peut être définie par une surface continue formée d'une pluralité de rayons dont les centres respectifs appartiennent à l'axe de rotation. Ainsi chaque liaison entre un point d'un arc de cercle et l'axe de rotation correspond à un rayon.Advantageously, the inner surface can be defined at least in part by a continuous surface formed of a plurality of parallel arcs between they whose respective centers belong to the axis of rotation. For example, these arcs can be identical to each other, and can be superimposed on each other other, so as to define with the first wall a volume delimiting a cylinder portion. In this case, both sides of the housing can respectively be defined by continuous surfaces formed of a plurality of connections between at least one point of each of these arcs and the axis of rotation. In particular, at least one of the two walls can be defined by a continuous surface formed of a plurality of spokes whose respective centers belong to the axis of rotation. Thus each connection between a point of an arc of circle and the axis of rotation corresponds to a radius.

En particulier, au moins l'une des deux parois, et de préférence les deux parois, peuvent être sensiblement planes.In particular, at least one of the two walls, and preferably both walls, can be substantially flat.

Selon un premier mode de réalisation, la surface intérieure du logement définit une portion de sphère ou portion sphérique. En particulier, elle peut être définie dans un quart de sphère ou bien une demi-sphère.According to a first embodiment, the inner surface of the housing defines a sphere portion or spherical portion. In particular, it can be defined in a quarter of a sphere or a half-sphere.

Selon un deuxième mode de réalisation, la surface intérieure du logement définit une portion de cylindre, par exemple un quart de cylindre.According to a second embodiment, the inner surface of the housing defines a cylinder portion, for example a quarter cylinder.

Par exemple, l'une des deux parois peut être rapportée sur l'autre des deux parois. Elles peuvent à cet effet par exemple comporter des moyens pour être monté en force l'une sur l'autre. Par exemple, des ergots présentés par la deuxième paroi sont prévus pour s'engager dans des gorges complémentaires prévues dans le récipient, l'axe de rotation de la charnière pouvant passer par ces ergots.For example, one of the two walls can be attached to the other of the two walls. For example, they may include means to be mounted in force on each other. For example, ergots presented by the second wall are planned to engage in complementary grooves provided in the container, the axis of rotation of the hinge can pass through these pins.

Alternativement, les deux parois peuvent être directement obtenues d'une seule pièce de moulage, dans ce cas un axe de rotation est matérialisé au niveau d'une charnière film définie à une jonction entre ces deux parois.Alternatively, the two walls can be directly obtained from a only one molding part, in this case an axis of rotation is materialized at the level of a film hinge defined at a junction between these two walls.

Par exemple, le récipient est obtenu par injection. En variante, l'une des parois est obtenue par surmoulage d'une première structure rigide, par exemple réalisée à partir de polyéthylène ou de polypropylène, avec une deuxième structure élastomère, la structure élastomère délimitant des bordures de cette paroi. Avec une telle structure, les tolérances de fabrication du logement sont absorbées par la partie élastomère qui maintient un contact étanche et un raclage efficace de la paroi mobile en rotation relativement à la surface intérieure.For example, the container is obtained by injection. Alternatively, one of the walls is obtained by overmolding a first rigid structure, for example made from polyethylene or polypropylene, with a second elastomer structure, the elastomeric structure delimiting borders of this wall. With such a structure, the housing manufacturing tolerances are absorbed by the elastomeric part which maintains a tight contact and scraping effective rotation of the movable wall relative to the inner surface.

Selon un mode de réalisation préféré, le dispositif comporte un support apte à reposer dans une position stable sur un plan. De préférence, ce support comporte une ouverture au niveau de laquelle débouche l'orifice de sortie, l'une des parois étant accessible depuis cette ouverture. Le récipient peut par exemple être clipsé dans le support. Alternativement, le support peut également se présenter sous la forme d'une jupe périphérique entourant le récipient, cette jupe pouvant être obtenue simultanément avec le récipient lors de l'injection de l'ensemble ainsi formé.According to a preferred embodiment, the device comprises a suitable support to rest in a stable position on a plane. Preferably, this support has an opening at which the outlet orifice opens, one of which walls being accessible since this opening. The container may for example be clipped into the holder. Alternatively, the support can also be present in the form of a peripheral skirt surrounding the container, this skirt can be obtained simultaneously with the container during the injection of the whole thus formed.

En particulier, l'invention a pour objet un ensemble comportant deux dispositifs tels que précédemment décrits, chaque dispositif comportant un récipient, tel que les récipients respectifs de ces deux dispositifs sont disposés de part et d'autre d'une cloison. Dans ce cas, et de préférence, les deux récipients peuvent coopérer chacun avec un battant distinct, les deux battants étant chacun monté rotatif autour d'un axe de rotation propre, mais solidaire de la cloison. En particulier, ces deux récipients peuvent être symétriques l'un de l'autre relativement à un plan passant par cette cloison. Avantageusement, la cloison comporte deux surfaces planes en vis-à-vis. Dans ce cas, et dans la mesure où deux battants rotatifs sont respectivement montés en coopération chacun avec un récipient, les axes de rotation de ces battants sont alors parallèles entre eux. Les deux récipients peuvent être accolés de manière à s'inscrire dans une demi sphère. Dans ce cas, les surfaces planes de part et d'autre de la cloison s'étendent de préférence dans des plans sécants, tels que l'écart angulaire entre ces deux surfaces planes est de l'ordre de 5 à 15°, chaque récipient ayant alors un volume légèrement inférieur à un quart de sphère.In particular, the subject of the invention is a set comprising two devices as previously described, each device comprising a container, such that the respective containers of these two devices are arranged on both sides of a partition. In this case, and preferably both containers can each cooperate with a separate wing, the two leaves being each rotatably mounted around a clean axis of rotation, but integral with the partition. In particular, these two containers may be symmetrical to each other in relation to a plan passing through that partition. Advantageously, the partition has two flat surfaces vis-à-vis. In this case, and to the extent that two rotary flaps are respectively mounted in cooperation each with a container, the axes of rotation of these wings are then parallel to each other. The two containers can be joined to register in a half sphere. In this case, the flat surfaces on both sides of the partition preferably extend in secant planes, such as the angular difference between these two flat surfaces is of the order of 5 to 15 °, each container having then a volume slightly less than a quarter of a sphere.

La figure 1 montre un dispositif 1 selon l'invention, ce dispositif 1 comportant un récipient 2 définissant un logement 4 apte à contenir une quantité de produit à conditionner. Une surface intérieure 5 du logement 4 est délimitée par au moins une première paroi 6, tandis qu'une deuxième paroi 3 du dispositif 1 permet d'obturer au moins partiellement ledit logement 4 du récipient 2. La deuxième paroi 3 définit en partie le pourtour extérieur du dispositif 1.FIG. 1 shows a device 1 according to the invention, this device 1 having a container 2 defining a housing 4 adapted to contain a quantity of product to be packaged. An inner surface 5 of the housing 4 is delimited by at least one first wall 6, while a second wall 3 of the device 1 at least partially closes said housing 4 of the container 2. second wall 3 partially defines the outer periphery of the device 1.

La surface intérieure 5 est définie par une surface continue formée d'une pluralité d'arcs de cercle. Chaque arc de cercle comporte un centre disposé sur un axe 7 également appelé axe des centres. Selon les figures 1 à 3, les arcs de cercle formant la surface intérieure 5 sont de même ouverture angulaire, et de même rayon. Chaque arc de cercle est de plus disposé de telle sorte que les deux extrémités respectives de chacun de ces arcs de cercle s'alignent respectivement selon deux lignes 8 et 9. Selon la Figure 1 les lignes 8 et 9 sont identiques et forment deux droites parallèles entre elles. Selon ce premier mode de réalisation, Figures 1 à 3, une ouverture angulaire de ces arcs de cercle est de 90°.The inner surface 5 is defined by a continuous surface formed of a plurality of circular arcs. Each arc has a center arranged on a axis 7 also called centers axis. According to Figures 1 to 3, the arches of circle forming the inner surface 5 are of the same angular aperture, and of same radius. Each arc is furthermore arranged so that both respective ends of each of these arcs align respectively according to two lines 8 and 9. According to Figure 1 lines 8 and 9 are identical and form two straight lines parallel to each other. According to this first embodiment, Figures 1 to 3, an angular opening of these arcs is 90 °.

La première paroi 6 est définie par une surface continue formée d'une pluralité de liaisons entre au moins un point de chaque arc de cercle et l'axe des centres 7. Chaque liaison est définie dans un plan orthogonal à l'axe des centres 7, de manière à ce que cette première paroi 6 soit également continue.The first wall 6 is defined by a continuous surface formed of a plurality of links between at least one point of each arc of the circle and the axis of centers 7. Each link is defined in a plane orthogonal to the center axis 7, so that the first wall 6 is also continuous.

Figures 1 et 2, ces liaisons sont droites, parallèles entre elles et de même longueur. La première paroi 6 est alors plane et se définit dans un plan passant par l'axe des centres 7. Selon les Figures 1, cette première paroi 6 passe par l'une des lignes passant par les extrémités des arcs de cercle, en l'occurrence ici la droite 9.Figures 1 and 2, these links are straight, parallel to each other and likewise length. The first wall 6 is then flat and is defined in a passing plane by the axis of the centers 7. According to FIG. 1, this first wall 6 passes through one lines passing through the ends of the arcs, in this case here the right 9.

La deuxième paroi 3 est articulée à la première paroi 6 de manière à pouvoir être entraínée en rotation autour de l'axe des centres 7, également appelé axe de rotation 7. Un écart angulaire 100 défini entre ces deux parois 3 et 6 varie en fonction du déplacement en rotation de la deuxième paroi 3 relativement à l'autre. Par exemple, Figures 1 à 3, l'écart angulaire 100 est prévu pour varier dans la plage définie entre 90° et 0°. En variante, la deuxième paroi 3 peut être apte à couvrir un écart angulaire 100 relativement à la première paroi 6 supérieur à l'ouverture angulaire de la surface intérieure 5.The second wall 3 is articulated to the first wall 6 so as to can be rotated around the center axis 7, also called axis of rotation 7. An angular difference 100 defined between these two walls 3 and 6 varies. depending on the rotational displacement of the second wall 3 relative to the other. For example, Figures 1 to 3, the angular deviation 100 is intended to vary in the range defined between 90 ° and 0 °. Alternatively, the second wall 3 can be adapted to cover an angular difference 100 relative to the first upper wall 6 at the angular opening of the inner surface 5.

Dans l'exemple présenté figures 1 à 15, la première paroi 6 est solidaire et forme en partie la surface intérieure 5, la deuxième paroi 3 étant rotative autour de l'axe 7. La deuxième paroi 3 vient en engagement étanche avec la surface intérieure 5 du logement lors de son déplacement en rotation autour de l'axe 7. La deuxième paroi 3 comporte donc un bord linéaire 50 allongé le long de l'axe 7, et un deuxième bord périphérique libre 51 au niveau duquel la deuxième paroi 3 vient au moins partiellement en contact étanche avec la surface intérieure 5. Le contour de ce deuxième bord libre 51 est de forme adaptée pour venir coopérer avec la surface intérieure 5.In the example shown in FIGS. 1 to 15, the first wall 6 is integral with and partially forms the inner surface 5, the second wall 3 being rotatable around the axis 7. The second wall 3 comes in sealed engagement with the surface interior 5 of the housing during its displacement in rotation about the axis 7. The second wall 3 thus comprises a linear edge 50 elongated along the axis 7, and a second free peripheral edge 51 at which the second wall 3 at least partially in sealing contact with the inner surface 5. The contour of this second free edge 51 is shaped to cooperate with with the inner surface 5.

Le volume intérieur restituable du logement 4 est défini par la rotation de la deuxième paroi 3 autour de l'axe 7 jusqu'à ce que l'ouverture angulaire maximale de la surface intérieure 5 ait été balayée et ou jusqu'à ce que la deuxième paroi 3 vienne en butée contre la première paroi 6.The releasable interior volume of the housing 4 is defined by the rotation of the second wall 3 around the axis 7 until the maximum angular aperture of the inner surface 5 has been swept and or until the second wall 3 come into abutment against the first wall 6.

En variante, non représentée, la première paroi 6 peut également être mobile relativement à la surface intérieure 5, en étant elle-aussi articulée autour de l'axe 7. Ainsi, un bord périphérique de cette première paroi 6 vient lui aussi en engagement avec la surface intérieure 5 lors de son engagement en rotation autour de l'axe 7. Les deux parois 3 et 6 sont alors rotatives autour de l'axe 7.Alternatively, not shown, the first wall 6 can also be mobile relative to the inner surface 5, being itself also articulated around of the axis 7. Thus, a peripheral edge of this first wall 6 also comes into engagement with the inner surface 5 when engaged in rotation around the axis 7. The two walls 3 and 6 are then rotatable about the axis 7.

Le récipient 2 définit une ouverture 10. Figure 2, l'ouverture 10 est délimitée entre la deuxième droite passant par les extrémités des arcs de cercle, ici la droite 8, et l'axe des centres 7. La surface intérieure 5 comporte de plus ici selon ce mode de réalisation, Figures 1 et 2, deux portions latérales 11 et 12 s'étendant orthogonalement à l'axe des centres 7 de manière à ce que le logement 4 définisse une cavité apte à y retenir un produit tel qu'une crème. Ces deux portions latérales 11 et 12 définissent des portions de disque identiques de secteur angulaire égal ou supérieur au secteur angulaire des portions d'arc de cercle de la surface intérieure 5. La cavité se définit alors comme un quart de cylindre, dont la hauteur se définit le long de l'axe des centres 7.The container 2 defines an opening 10. FIG. 2, the opening 10 is delimited between the second straight line passing through the ends of arcs, here the right 8, and the axis of the centers 7. The inner surface 5 further comprises here according to Embodiment, Figures 1 and 2, two side portions 11 and 12 extending orthogonal to the axis of the centers 7 so that the housing 4 define a cavity adapted to retain a product such as a cream. These two side portions 11 and 12 define identical disk portions of angular sector equal to or greater than the angular sector of the arc portions of circle of the inner surface 5. The cavity is then defined as a quarter of cylinder, the height of which is defined along the axis of the centers 7.

Cette ouverture 10 est en partie obturée par la deuxième paroi 3. Le produit est disposé dans le récipient 2, sous cette deuxième paroi 3. En effet, la deuxième paroi 3, en coopération avec le logement 4 définit un volume 16. La deuxième paroi 3 est munie d'un orifice de sortie 14 par lequel le produit contenu dans le volume 16 du logement 4 peut être distribué. En effet, le volume 16 varie en fonction du déplacement de la deuxième paroi 3 relativement au logement 4 autour de l'axe 7, le produit étant comprimé de manière à fluer par l'orifice de sortie 14 hors du dispositif 1. L'utilisatrice appuie directement sur la surface extérieure de la deuxième paroi 3, là où débouche l'orifice de sortie 14This opening 10 is partly closed by the second wall 3. The product is placed in the container 2, under this second wall 3. In fact, the second wall 3, in cooperation with the housing 4 defines a volume 16. The second wall 3 is provided with an outlet orifice 14 through which the product contained in the volume 16 of the housing 4 can be distributed. Indeed, volume 16 varies in function of the displacement of the second wall 3 relative to the housing 4 around the axis 7, the product being compressed so as to flow through the orifice of exit 14 out of the device 1. The user presses directly on the surface outside the second wall 3, where the outlet 14 opens

L'orifice de sortie 14 est défini au niveau de la deuxième paroi 3. Le flux de produit sortant est alors orthogonal à la paroi présentant ledit orifice de sortie 14. Ces parois 3 et 6 étant rotatives autour de l'axe 7, l'axe 7 est inclus dans l'épaisseur de ces parois. L'orifice de sortie 14 traversant nécessairement l'épaisseur de la deuxième paroi 3, il oriente donc un flux de produit le traversant selon une direction distincte de celle de l'axe 7.The outlet orifice 14 is defined at the level of the second wall 3. The flow of outgoing product is then orthogonal to the wall having said outlet orifice 14. These walls 3 and 6 being rotatable about the axis 7, the axis 7 is included in the thickness of these walls. The outlet orifice 14 necessarily crossing the thickness of the second wall 3, it thus directs a flow of product through it in a direction distinct from that of axis 7.

En l'occurrence, comme représenté sur les figures 1 à 3, l'orifice de sortie 14 est défini au travers de la deuxième paroi 3. L'orifice de sortie 14 est de préférence définie dans la deuxième paroi 3 à proximité d'une charnière 13. La présence de cet orifice de sortie 14 sur la deuxième paroi 3 empêche ladite deuxième paroi 3 d'obturer complètement l'ouverture 10.In this case, as shown in FIGS. 1 to 3, the outlet orifice 14 is defined through the second wall 3. The outlet orifice 14 is defined in the second wall 3 near a hinge 13. The presence of this outlet orifice 14 on the second wall 3 prevents said second wall 3 to completely close the opening 10.

En variante, l'orifice de sortie 14 peut être défini au niveau du bord périphérique libre 51 de la deuxième paroi 3 configurée pour ne pas venir, au moins localement pour former cet orifice 14, au contact de la surface intérieure 5, ou de l'une des portions latérales 11 et 12 le cas échéant.Alternatively, the outlet port 14 may be defined at the edge free device 51 of the second wall 3 configured to not come, at less locally to form this orifice 14, in contact with the inner surface 5, or one of the side portions 11 and 12 where appropriate.

Comme représenté Figure 2, lorsqu'un utilisateur exerce une pression, à l'aide d'au moins un de ses doigts directement sur la deuxième paroi 3, celle-ci est entraínée en rotation autour de la charnière 13, formée autour de l'axe 7, et dans la mesure où le bord périphérique 51 vient racler contre la surface intérieure 5, et ici aussi contre les portions latérales 11 et 12, le produit est alors concentré dans le logement 4 jusqu'à ce que le volume 16 soit insuffisant par rapport au volume de produit restant. Le volume de produit en excès est alors expulsé par l'orifice de sortie 14, où l'utilisateur peut le prélever directement au doigt. La deuxième paroi 3 étant accessible depuis le pourtour extérieur du dispositif 1, la poussée est exercée sur la surface extérieure de la deuxième paroi 3 dans la même direction que le déplacement obtenu de cette deuxième paroi 3.As shown in Figure 2, when a user exerts pressure, using at least one of his fingers directly on the second wall 3, the latter is driven in rotation around the hinge 13, formed around the axis 7, and in the extent to which the peripheral edge 51 scrapes against the inner surface 5, and here also against the lateral portions 11 and 12, the product is then concentrated in the housing 4 until the volume 16 is insufficient in relation to the volume of remaining product. The volume of excess product is then expelled through the orifice of exit 14, where the user can take it directly on the finger. The second wall 3 being accessible from the outer periphery of the device 1, the thrust is exerted on the outer surface of the second wall 3 in the same direction that the displacement obtained from this second wall 3.

La deuxième paroi 3 a selon les figures 1 et 2 une structure plane, elle peut ainsi coopérer efficacement avec la première paroi 6, également plane selon les Figures 1 et 2. Notamment pour une vidange maximale du récipient 2, les deux parois 3 et 6 viennent s'appliquer l'une contre l'autre jusqu'à ce qu'il ne reste plus qu'un film infime de produit entre elles à ne pouvoir être expulsé par l'orifice de sortie 14. Initialement, la deuxième paroi 3 est prévue pour pouvoir venir au contact de chacun des arcs de cercle au niveau de la droite 8, et venir ensuite sur toute la courbure intérieure de ces arcs de cercle en contact intime pour assurer l'étanchéité de cette jonction. C'est pourquoi la deuxième paroi 3 est articulée autour d'un axe passant par les centres de chacun de ces arcs de cercle.The second wall 3 has according to FIGS. 1 and 2 a planar structure, it can thus cooperate effectively with the first wall 6, also flat according to the Figures 1 and 2. In particular for maximum emptying of the container 2, both walls 3 and 6 are applied against each other until no longer that a minute film of product between them to be able to be expelled by the orifice of exit 14. Initially, the second wall 3 is planned to come to contact each of the arcs on the line 8, and then come on all the inner curvature of these arcs in intimate contact to ensure the tightness of this junction. This is why the second wall 3 is articulated around an axis passing through the centers of each of these arcs.

En variante, comme cela est schématiquement représenté sur la vue en coupe de la Figure 3, la deuxième paroi 3 peut ne pas être plane, dans ce cas, on la choisit de telle sorte qu'elle puisse néanmoins coopérer tout aussi efficacement avec la deuxième paroi 6. Cette deuxième paroi 6 est alors elle aussi de forme non plane et surtout complémentaire de celle de la deuxième paroi 3. La figure 11 représente un dispositif selon l'invention pour lequel les deux parois 3 et 6 sont ondulées, superposables, et rattachées au niveau de la charnière 13 formant l'axe de rotation 7. La surface intérieure 5 présente selon les modes de réalisation des Figures 3 et 11 une structure formant une portion de cylindre et pour laquelle la surface intérieure 5 comporte des portions latérales 11 et 12, ces portions étant planes et comportant de préférence deux bords ondulés et superposables.In a variant, as is schematically represented in the view in section of Figure 3, the second wall 3 may not be flat, in which case chooses it so that it can nevertheless cooperate just as effectively with the second wall 6. This second wall 6 is then also shaped not flat and especially complementary to that of the second wall 3. Figure 11 represents a device according to the invention for which the two walls 3 and 6 are corrugated, stackable, and attached at the hinge 13 forming the axis 7. The inner surface 5 has, according to the embodiments of the Figures 3 and 11 a structure forming a cylinder portion and for which the inner surface 5 has lateral portions 11 and 12, these portions being planes and preferably having two corrugated and superimposable edges.

De préférence, on définit la structure de la deuxième paroi 3 de manière à ce qu'elle puisse venir s'accoler en tous points contre la première paroi 6, et ainsi avoir un taux de restitution optimal. Par taux de restitution, on entend la proportion de produit qui est délivré par un tel dispositif 1 relativement à la quantité totale de produit qui y est conditionnée. Ainsi il n'existe pas de poche résiduelle entre les deux parois 3 et 6, et tout le produit contenu dans la volume 16 peut être expulsé par l'orifice de sortie 14.Preferably, the structure of the second wall 3 is defined so as to it can come to stick in all points against the first wall 6, and so have an optimal restitution rate. The rate of refund means the proportion product that is delivered by such a device 1 relative to the total quantity of product that is packaged there. Thus there is no residual pocket between two walls 3 and 6, and all the product contained in volume 16 can be expelled through the outlet 14.

A cet effet, et dans ce cas, la deuxième paroi 3 tout comme la première paroi 6 sont formées par une pluralité de liaisons, chacune définie dans un plan orthogonal à l'axe des centres 7 telle qu'une liaison formant l'une de ces parois 3 ou 6, définies dans un même plan, sont superposables, comme cela est représenté Figure 3. Ces liaisons peuvent proposer une forme de courbe.For this purpose, and in this case, the second wall 3 as the first wall 6 are formed by a plurality of links, each defined in a plane orthogonal to the axis of the centers 7 such that a connection forming one of these walls 3 or 6, defined in the same plane, are superimposable, as is Figure 3. These links may provide a form of curve.

Figures 4 à 7 et 9, 10, 12 et 13, la deuxième paroi 3 présente un bord libre 51 ne comportant aucun segment orthogonal à l'axe 7, la surface intérieure 5 ne comporte alors pas de portions latérales telles que 11 et 12.Figures 4 to 7 and 9, 10, 12 and 13, the second wall 3 has a free edge 51 having no segment orthogonal to the axis 7, the inner surface 5 does not then has no lateral portions such as 11 and 12.

Figure 4, la surface intérieure 5 présente une surface formée par un quart de sphère. Dans ce cas, la deuxième paroi 3 et la première paroi 6 sont de forme identique, de préférence plane et formant respectivement chacun un demi-disque dont le rayon correspond au rayon du quart de sphère définissant cette surface intérieure 5. L'orifice de sortie 14 est ici présenté sur la deuxième paroi 3. Par exemple, les deux parois 3 et 6 et la surface intérieure 5 sont monobloc et sont obtenues par injection d'un matériau thermoplastique tel que du polyéthylène ou du polypropylène. La deuxième paroi 3 est alors moulée dans l'alignement de la première paroi 6, de telle sorte qu'une jonction linéaire entre ces deux parois 3 et 6 forme un amincissement le long de l'axe des centres 7, formant ainsi la zone de flexion, ou charnière 13, permettant la rotation de la deuxième paroi 3.4, the inner surface 5 has a surface formed by a quarter of sphere. In this case, the second wall 3 and the first wall 6 are of shape identical, preferably flat and respectively forming respectively a half-disk whose radius corresponds to the radius of the quarter sphere defining this surface 5. The outlet orifice 14 is here presented on the second wall 3. By for example, the two walls 3 and 6 and the inner surface 5 are monobloc and are obtained by injection of a thermoplastic material such as polyethylene or polypropylene. The second wall 3 is then molded in alignment with the first wall 6, so that a linear junction between these two walls 3 and 6 forms a thinning along the axis of the centers 7, thus forming the zone of bending, or hinge 13, allowing rotation of the second wall 3.

Figures 5 et 6, le réservoir 2 présente un logement 4 défini dans une demi sphère. Dans ce cas, la surface intérieure 5 est moulée séparément en forme de cupule hémisphérique, et la deuxième paroi 6 peut être moulée avec la première paroi 3 en forme de disque tel qu'une moitié de ce disque est soudée sur les bords de cette cupule, de telle sorte qu'une charnière film délimite les bords de ce demi-disque soudé à la cupule. La charnière film est définie le long d'un diamètre de ce disque de manière à former deux demi-disques superposables formant respectivement chacune des parois 3 et 6. La deuxième paroi 3 est alors rotative autour de cette charnière et peut être entraínée en rotation à l'intérieur de la cupule.Figures 5 and 6, the reservoir 2 has a housing 4 defined in a half sphere. In this case, the inner surface 5 is molded separately in the form of hemispherical cup, and the second wall 6 can be molded with the first wall 3 in the form of a disc such that a half of this disc is welded on the edges of this cup, so that a film hinge delimits the edges of this half-disc welded to the cup. The film hinge is defined along a diameter of this disc so as to form two superimposable half-disks forming respectively each of the walls 3 and 6. The second wall 3 is then rotatable around this hinge and can be rotated within the cup.

En particulier, la cupule peut comporter, sur son pourtour intérieur, deux ergots diamétralement opposés pour venir soutenir la deuxième paroi 6 lors de sa mise en place sur la cupule formée par la surface intérieure 5. Ces deux ergots affleurent dans un même plan que les bords de la cupule. De préférence, on dispose la charnière film en appui sur ces deux ergots. Dans ce cas, l'écart angulaire 100 peut varier d'au moins 180° à 0° de manière à progressivement diminuer le volume 16 hémisphérique.In particular, the cup may have, on its inner periphery, two diametrically opposite pins to come support the second wall 6 at its placed on the cup formed by the inner surface 5. These two lugs outcrop in the same plane as the edges of the cup. Preferably, has the film hinge resting on these two lugs. In this case, the gap angle can vary from at least 180 ° to 0 ° so as to progressively decrease the hemispheric volume.

Selon la vue en coupe de la figure 6, une poussée exercée selon la flèche 15 entraíne la deuxième paroi 3 en rotation autour de la charnière film 13 se superposant avec l'axe des centres 7. Le produit comprimé dans le logement 4 dont le volume 16 diminue est donc poussé au travers de l'orifice de sortie 14. Le bord périphérique 51 vient racler le pourtour intérieur de la surface intérieure 5.According to the sectional view of FIG. 6, a thrust exerted according to the arrow 15 causes the second wall 3 in rotation around the hinge film 13 se superimposed with the axis of the centers 7. The compressed product in the housing 4 whose volume 16 decreases is thus pushed through the outlet orifice 14. The peripheral edge 51 scrapes the inner periphery of the inner surface 5.

Selon un mode de réalisation particulier, au moins la deuxième paroi 3 est obtenue de surmoulage d'une première structure rigide 17, par exemple en polyéthylène ou en polypropylène, avec un matériau élastomère 18, ce matériau élastomère constituant de préférence la bordure périphérique 51 au contact de la surface intérieure 5. Ainsi le raclage se fait de manière optimale. Comme représenté sur la Figure 7, une deuxième paroi 3 ainsi surmoulée apte à être montée sur l'un des récipients selon les figures 4 à 6 est ainsi représentée.According to a particular embodiment, at least the second wall 3 is obtained by overmolding a first rigid structure 17, for example into polyethylene or polypropylene, with an elastomeric material 18, this material elastomer preferably constituting the peripheral rim 51 in contact with the inner surface 5. Thus the scraping is done optimally. As represented in FIG. 7, a second wall 3 thus overmoulded capable of being mounted on one of the containers according to Figures 4 to 6 is thus shown.

En particulier, cette deuxième paroi 3, Figure 7, présente deux ergots 19 et 20 diamétralement opposés et aptes à venir coopérer avec deux gorges complémentaires présentées par la surface intérieure 5 ou la deuxième paroi 6, de manière à former la charnière 13 autour de laquelle la deuxième paroi 3 pourra être entraínée en rotation. La position des gorges et des ergots peut être respectivement inversée. Dans tous les cas, les deux gorges complémentaires sont disposées selon un axe correspondant à l'axe des centres 7 de la surface intérieure 5.In particular, this second wall 3, FIG. 7, has two lugs 19 and 20 diametrically opposed and able to cooperate with two throats complementary elements presented by the inner surface 5 or the second wall 6, of to form the hinge 13 around which the second wall 3 can be rotated. The position of the grooves and lugs can be respectively reversed. In all cases, the two complementary grooves are arranged along an axis corresponding to the axis of the centers 7 of the surface inside 5.

Figure 12, une variante de réalisation d'un dispositif 1 selon l'invention comporte une deuxième paroi 3 telle que son bord périphérique 51 définit une courbe irrégulière ne comportant aucun segment s'étendant orthogonalement à l'axe 7. En particulier, la courbe irrégulière de la Figure 12 comporte trois excroissances respectivement 52, 53 et 54 s'allongeant orthogonalement à l'axe 7. De manière complémentaire, la surface intérieure 5 s'inscrit dans une cupule irrégulière.Figure 12, an alternative embodiment of a device 1 according to the invention has a second wall 3 such that its peripheral edge 51 defines a irregular curve with no segment extending orthogonally to axis 7. In particular, the irregular curve of Figure 12 has three protuberances respectively 52, 53 and 54 extending orthogonally to the axis 7. In a complementary manner, the inner surface 5 is part of a cup irregular.

En variante, Figure 13, la deuxième paroi 3 est triangulaire, le bord périphérique 51 définissant deux côtés de ce triangle, le troisième côté formant une base 50 s'allongeant le long de l'axe de rotation 7. Dans cet exemple, l'orifice de distribution 14 est situé à distance de l'axe 7, dans la pointe définie par ce triangle. Des hauteurs telles que 55, orthogonale à l'axe 7, définissant respectivement des rayons pour les arcs de cercle correspondant et formant la surface intérieure 5. As a variant, FIG. 13, the second wall 3 is triangular, the edge peripheral 51 defining two sides of this triangle, the third side forming a base 50 extending along the axis of rotation 7. In this example, the orifice 14 is located at a distance from the axis 7, in the point defined by this triangle. Heights such as 55, orthogonal to axis 7, defining respectively radii for the corresponding circular arcs and forming the inner surface 5.

Figures 8 et 14, une variante de réalisation d'un récipient 2 réalisé selon les modalités de l'invention est représenté, la figure 8 correspondant à une vue de dessus du récipient de la figure 14. La surface intérieure 5 a dans cette variante une forme de portion de cylindre, la portion de cylindre comportant de plus une excroissance radiale, formant une portion de jonc de même ouverture angulaire que la portion de cylindre. Cette excroissance a en particulier, et selon une vue en coupe longitudinale, une section triangulaire 21 dépassant d'un bord 22 de la portion de cylindre 23.Figures 8 and 14, an alternative embodiment of a container 2 made according to the the embodiments of the invention is shown, FIG. 8 corresponding to a view of above the container of Figure 14. The inner surface 5 has in this variant a cylinder portion shape, the cylinder portion further comprising a radial outgrowth, forming a rod portion of the same angular aperture than the cylinder portion. This growth has in particular, and according to a view in longitudinal section, a triangular section 21 protruding from an edge 22 of the cylinder portion 23.

Dans tous les exemples de dispositif selon l'invention représentés sur les Figures 1 à 6, le récipient 2 présente une épaisseur de paroi toujours sensiblement identique que ce soit pour définir la surface intérieure 5 ou la première paroi 6. De ce fait, un récipient 2 présente toujours au moins une paroi extérieure incurvée. Par conséquent, un tel dispositif ne peut pas forcément être placé de manière stable sur des plans tels que des étagères, tout en orientant vers le haut l'orifice de sortie 14 de manière à éviter les fuites de produit par gravité.In all the examples of device according to the invention represented on the Figures 1 to 6, the container 2 has a wall thickness always substantially identical whether to define the inner surface 5 or the first wall 6. As a result, a container 2 always has at least one wall curved exterior. Therefore, such a device can not necessarily be stably positioned on plans such as shelves, while orienting upwardly the outlet orifice 14 so as to prevent leakage of product by gravity.

Pour pouvoir placer un dispositif selon l'invention de manière stable sur un plan, on peut choisir de proposer un récipient dont l'épaisseur des parois varie, de manière à proposer au moins deux faces planes sécantes sur le pourtour extérieur de la surface intérieure 5.To be able to place a device according to the invention stably on a plan, we can choose to propose a container whose wall thickness varies, from in order to propose at least two secant plane faces on the outer periphery of the inner surface 5.

Alternativement, on peut aussi choisir de monter le récipient 2 dans un support 24. Par exemple, comme représenté, figure 9, le support 24 a une structure cylindrique, comportant une base 25 sur laquelle il peut reposer de manière stable. Le support 24 comporte de plus une ouverture 26 par laquelle le récipient 2 peut être inséré dans le support 24. L'ouverture 26 est parallèle à la base 25. Elle s'étend orthogonalement à un axe longitudinal X du support 24. Par exemple, le récipient 2 comporte une collerette externe pour coopérer avec un relief complémentaire du pourtour intérieur du support 24, dans le but d'être retenu dans ce support 24. Alternatively, one can also choose to mount the container 2 in a 24. For example, as shown in FIG. 9, the support 24 has a cylindrical structure, having a base 25 on which it can rest from stably. The support 24 further includes an opening 26 through which the container 2 can be inserted into the support 24. The opening 26 is parallel to the 25. It extends orthogonally to a longitudinal axis X of the support 24. By For example, the container 2 has an external flange to cooperate with a complementary relief of the inner periphery of the support 24, in order to be retained in this support 24.

Dans l'exemple représenté Figure 9, le support 24 comporte un couvercle 27 apte à obturer l'ouverture 26. Par exemple ce couvercle est configuré pour être vissé sur un pas de vis 28 présenté sur le pourtour extérieur d'un col délimitant l'ouverture 26.In the example shown in FIG. 9, the support 24 comprises a cover 27 adapted to close the opening 26. For example this lid is configured to be screwed on a thread 28 presented on the outside perimeter of a collar defining the opening 26.

En particulier, Figures 9, 10 et 15, un premier récipient 29 et un deuxième récipient 30 respectivement tels que 2 sont définis de part et d'autre d'une cloison 31. Chacun des deux récipients 29 et 30 comporte pour l'occasion un battant 32 et respectivement 33, matérialisant les deuxièmes parois telles que 3, chaque battant coopérant avec la surface intérieure telle que 5 de l'un des récipients. La cloison 31 s'étend orthogonalement aux plans d'ouverture tels que 10 de ces deux récipients et à l'ouverture 26. Les deux récipients peuvent être symétriques l'un de l'autre relativement à un plan passant par la cloison 31.In particular, Figures 9, 10 and 15, a first container 29 and a second container 30 respectively such that 2 are defined on both sides of a partition 31. Each of the two containers 29 and 30 comprises for the occasion a leaf 32 and respectively 33, materializing the second walls such as 3, each flapping cooperating with the inner surface such as 5 of one of the containers. The partition 31 extends orthogonally to the opening planes such as 10 of these two at the opening 26. The two receptacles may be symmetrical, one of them the other in relation to a plane passing through partition 31.

De préférence, la cloison 31 comporte deux faces planes 31 a et 31b matérialisant les premières parois telles que 6 de chaque récipient. Chaque récipient 29 et 30 définit par exemple, Figures 9 et 10, une chambre en portion de sphère, et en l'occurrence sensiblement en quart de sphère. Les battants 32 et 33 sont alors en forme de demi disque, et sont reliés chacun respectivement par une charnière film 34 et respectivement 35 à une bande centrale 36 de longueur sensiblement égale au diamètre intérieur de chacun des deux récipients 29 et 30.Preferably, the partition 31 has two flat faces 31a and 31b materializing the first walls such as 6 of each container. Each container 29 and 30 defines, for example, Figures 9 and 10, a chamber in portion of sphere, and in this case substantially quarter-sphere. The leaves 32 and 33 are then in the form of a half-disk, and are respectively connected by a hinge film 34 and respectively 35 to a central band 36 in length substantially equal to the inside diameter of each of the two containers 29 and 30.

Cette bande centrale 36 est destinée à coopérer avec une portion 37 de la cloison 31, de manière à assurer la rétention de ces battants sur leur récipient respectif, de telle sorte que cette coopération soit apte à résister aux contraintes qui leur seront ensuite appliquées, notamment lorsque les battants seront entraínés en rotation autour de leur charnière respective en vue de faire fluer un produit hors desdits récipients. Dans le cas présent, les deux charnières sont parallèles entre elles. De préférence, la bande centrale 36 comporte des pattes élastiquement déformables telles que 60 aptes à être engagées par encliquetage dans des gorges complémentaires telles que 61 prévues dans la portion 37.This central strip 36 is intended to cooperate with a portion 37 of the partition 31, so as to ensure the retention of these leaves on their container respective, so that this cooperation is able to resist the constraints which will then be applied to them, especially when the wings will be rotated around their respective hinges in order to make a produced out of said containers. In this case, the two hinges are parallel to each other. Preferably, the central strip 36 has tabs elastically deformable such as 60 adapted to be engaged by snapping in complementary grooves such as 61 provided in the portion 37.

En particulier, pour renforcer l'encliquetage, la portion 37 comporte au moins un pignon 62 engagé au travers d'une gorge complémentaire 63 formée dans la bande centrale 36.In particular, to reinforce the latching, the portion 37 comprises at less a pinion 62 engaged through a complementary groove 63 formed in the central band 36.

De préférence deux produits différents sont conditionnés dans les deux récipients 29 et 30. En particulier, on y dispose des produits dont le mélange ne doit être réalisé que très peu de temps avant l'application, pour éviter qu'ils ne se dégradent mutuellement. Avantageusement, et dans la mesure où ces deux produits sont destinés à être mélangés avant application, on dispose de préférence, des orifices de sorties 38 et respectivement 39 tels que 14 pour chacun des battants 32 et 33 à proximité de la bande centrale 36. Ces orifices de sortie 38 et 39 sont par exemple légèrement décalés l'un par rapport à l'autre de manière à ne pas être symétrique l'un de l'autre relativement à un plan passant par la cloison 31 de manière à éviter toute contamination involontaire des deux récipients.Preferably two different products are packaged in both In particular, there are products whose mixture does not should be realized only a very short time before the application, to prevent them from mutually degrade. Advantageously, and to the extent that these two products are intended to be mixed before application, we have preferably, outlet orifices 38 and 39, respectively, such as 14 for each of the leaves 32 and 33 near the central strip 36. These orifices of output 38 and 39 are for example slightly offset relative to each other so as not to be symmetrical to one another in relation to a passing plane by the partition 31 so as to avoid any involuntary contamination of both containers.

Alternativement, Figure 15, si les deux produits sont destinés à une utilisation bien séparée, par exemple l'une le jour et l'autre la nuit, les deux orifices peuvent êtres disposés dans des régions plus centrales de leur battant respectif, afin de limiter les risques de sortie de produit à proximité l'un de l'autre.Alternatively, Figure 15, if both products are intended for use well separated, for example one day and one night, both holes can be arranged in more central regions of their respective leaves, in order to limit the risk of product exit in the vicinity of each other.

Dans tous les cas, comme cela est représenté Figure 10, une utilisatrice peut n'avoir prélevé du produit que d'un seul côté, en appuyant sur un seul des deux battants. En effet, les deux charnières 34 et 35 sont indépendantes l'une de l'autre. Selon cet exemple, l'utilisatrice a déjà prélevé du produit disposé sous le battant 33, alors qu'aucun produit n'a encore été prélevé du récipient 29.In all cases, as shown in Figure 10, a user may have taken only one side of the product, pressing only one of the two leaves. Indeed, the two hinges 34 and 35 are independent one of the other. According to this example, the user has already taken from the product placed under the beating 33, while no product has yet been taken from the container 29.

Figure 15, les deux battants 32 et 33 sont en forme de triangle rectangle inscrits dans une ouverture 26 également triangulaire, tel que l'axe de rotation 7 soit orthogonal à une base du triangle isocèle formé par cette ouverture 26.Figure 15, the two leaves 32 and 33 are in the shape of a right triangle inscribed in an opening 26 also triangular, such as the axis of rotation 7 is orthogonal to a base of the isosceles triangle formed by this opening 26.

Pour le remplissage de tels dispositifs de conditionnement, soit le récipient est rempli avant que la deuxième paroi telle que 3, 32 ou 33 ne soit rabattue sur le récipient, soit le logement 4 est rempli alors que la deuxième paroi obture déjà en partie l'ouverture telle que 10 de ce récipient. Dans ce dernier cas, le produit peut être directement introduit via l'orifice de sortie 14. For the filling of such conditioning devices, either the container is filled before the second wall such as 3, 32 or 33 is folded down on the container, or the housing 4 is filled while the second wall already closes. part the opening such as 10 of this container. In the latter case, the product may be introduced directly via the outlet orifice 14.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, the phrase "with one" must be considered to be synonymous with "having at least one" unless the opposite is specified.

Dans les exemples, l'ouverture angulaire de la surface intérieure 5 est de l'ordre de 90° ou de 180°, mais cette ouverture angulaire peut prendre toute valeur strictement inférieure à 360°, et de préférence inférieure ou égale à 270°.In the examples, the angular aperture of the inner surface 5 is the order of 90 ° or 180 °, but this angular opening can take any value strictly less than 360 °, and preferably less than or equal to 270 °.
