The device may include a second compartment defining an opening and being in one of selective and permanent flow communication with the first compartment via at least one orifice. The second compartment may be configured to at least partially receive an applicator for applying the product, and may define a volume which is substantially fixed. The device may include a closure element configured to close off the opening of the second compartment. The device may be configured so that the height of the device diminishes as the volume of the first compartment becomes reduced, and at a last use of the device, the axial height of the device may be less than the axial height of the device at a first use of device.

Description

La présente invention concerne un ensemble pour le conditionnement et l'application d'un produit cosmétique.The present invention relates to an assembly for packaging and the application of a cosmetic product.

Par produit cosmétique on entend un produit tel que défini dans la directive 93/ 35/ CEE du Conseil du 14 juin 1993, modifiant pour la sixième fois la directive 76/ 768/ CEE.By cosmetic product is meant a product as defined in directive 93 / 35 / EEC of the Council of June 14, 1993, amending for the sixth time the Directive 76/768 / EEC.

L'invention est tout particulièrement adaptée pour les produits sous forme d'un liquide, d'un gel ou d'une crème. A titre d'exemple, on citera le conditionnement et l'application de produits de soin, notamment de la peau ou du cheveu, des produits de maquillage, des démaquillants ou des produits de coloration capillaire.The invention is particularly suitable for products in the form of a liquid, gel or cream. By way of example, mention may be made of packaging and the application of care products, in particular of the skin or the hair, make-up products, make-up removers or coloring products capillary.

Dans le domaine de la cosmétique notamment, certains produits, notamment sous forme d'un lait, d'une crème ou d'un gel sont distribués sous pression au moyen d'une pompe. En raison de leur instabilité en présence d'air, ils peuvent être conditionnés dans des systèmes à pompe du type sans reprise d'air, c'est-à-dire conditionnés sous vide dans des réservoirs dont le volume diminue au fil des utilisations. Typiquement, on utilise une poche à parois rétractables, un tube à parois déformables, ou un flacon dans lequel est disposé un piston suiveur. La pompe peut être du type à piston, à membrane ou à clapet.In the field of cosmetics in particular, certain products, in particular in the form of a milk, a cream or a gel are distributed under pressure to the by means of a pump. Due to their instability in the presence of air, they can be packaged in pump systems of the type without return air, i.e. vacuum packed in tanks whose volume decreases over time uses. Typically, a pocket with retractable walls is used, a tube with deformable walls, or a bottle in which is placed a piston follower. The pump can be of the piston, diaphragm or valve type.

Pour appliquer le produit, l'utilisatrice prélève le produit pompé sur l'un ou plusieurs de ses doigts, et l'applique en massant la surface à traiter. Alternativement, le produit est appliqué au moyen d'un applicateur, notamment sous forme d'une mousse à cellules ouvertes. To apply the product, the user takes the pumped product from one or more several of his fingers, and applies it by massaging the surface to be treated. Alternatively, the product is applied by means of an applicator, in particular as an open cell foam.

Dans le cas d'un applicateur réutilisable de nombreuses fois, en particulier tout au long de la durée de vie du produit, il peut être souhaitable que celui-ci, entre deux utilisations, soit stocké à l'abri de l'air de manière à ce que ses propriétés mécaniques, notamment de souplesse, ou d'absorption ne soient pas altérées. En outre, dans le cas d'un applicateur qui n'est pas nettoyé après chaque utilisation, le contact du produit restant sur l'applicateur avec l'air ambiant, ou avec tout autre élément de l'environnement dans lequel il est conservé, risque de souiller l'applicateur et d'altérer le produit qu'il porte. En tout état de cause, le transport d'un tel applicateur, notamment dans le sac à mains de l'utilisatrice, n'est pas sans poser de problèmes.In the case of an applicator which can be reused many times, in particular all over the life of the product, it may be desirable that it, between two uses, be stored away from air so that its mechanical properties, in particular flexibility, or absorption are not not altered. In addition, in the case of an applicator which is not cleaned after each use, the contact of the product remaining on the applicator with the air ambient, or with any other element of the environment in which it is preserved, risk of contaminating the applicator and altering the product it carries. In in any event, the transport of such an applicator, in particular in the hands, is not without problems.

Enfin, pour certains applicateurs, dont la forme est appropriée au profil de la surface à traiter, notamment au profil des lèvres ou du coin de l'oeil, il peut être souhaitable que le produit soit déposé toujours de la même manière sur l'applicateur, et dans les mêmes quantités, de manière à réaliser une application qui soit reproductible d'une fois à la fois suivante.Finally, for certain applicators, the shape of which is appropriate to the profile of the surface to be treated, in particular on the profile of the lips or the corner of the eye, it can be desirable that the product is always deposited in the same way on the applicator, and in the same quantities, so as to achieve a application that can be reproduced from one time to the next.

Les documents EP-A 0 416 185, EP-A-0 931 476, et US-A-5 636 931 décrivent un ensemble à deux logements, en communication l'un avec l'autre. L'un des deux logements est destiné à recevoir un applicateur solidaire d'un élément de préhension sous forme d'un bouchon apte à obturer une ouverture du logement contenant l'applicateur. L'élément de fermeture est solidaire d'un mécanisme apte, en réponse à une rotation par rapport au corps de l'ensemble, à permettre de pressuriser le produit contenu dans le premier logement de manière à en forcer la sortie dans le logement contenant l'applicateur. A cet effet, la paroi séparant les deux logements est configurée sous forme d'un piston qui est mobile, axialement et/ou en rotation, à l'intérieur de l'ensemble. La hauteur axiale de l'ensemble ne varie pas lors du mouvement du piston et l'encombrement de l'ensemble reste inchangé tout au long de son utilisation. Documents EP-A 0 416 185, EP-A-0 931 476, and US-A-5 636 931 describe a set with two housings, in communication with each other. One of the two housings is intended to receive an applicator integral with an element of gripping in the form of a plug capable of closing an opening in the housing containing the applicator. The closure element is integral with a mechanism able, in response to rotation relative to the body of the assembly, to allow to pressurize the product contained in the first housing of so as to force the outlet into the housing containing the applicator. In this Indeed, the wall separating the two housings is configured in the form of a piston which is movable, axially and / or in rotation, inside the assembly. The axial height of the assembly does not vary during the movement of the piston and the overall dimensions of the assembly remain unchanged throughout its use.

Aussi, est-ce un des objets de l'invention que de fournir un ensemble de conditionnement et d'application, résolvant en tout ou partie les problèmes discutés ci-avant en référence aux dispositifs conventionnels.It is therefore one of the objects of the invention to provide a set of conditioning and application, solving all or part of the problems discussed above with reference to conventional devices.

C'est en particulier un objet de l'invention que de fournir un dispositif qui soit adapté en particulier aux produits à forte viscosité, notamment sous forme de gels, de crèmes, ou de pâtes.It is in particular an object of the invention to provide a device which is particularly suitable for products with high viscosity, in particular in the form of gels, creams, or pasta.

C'est encore un objet de l'invention que de permettre un chargement précis et reproductible en produit d'un organe d'application.It is also an object of the invention to allow precise loading and reproducible as a product of an application organ.

C'est un autre objet encore que de fournir un tel ensemble qui soit simple d'utilisation, et qui soit économique à réaliser.It is yet another object to provide such a set which is simple of use, and which is economical to produce.

Selon l'invention, ces objets sont atteints en réalisant un ensemble d'axe X, pour le conditionnement et l'application d'un produit cosmétique, comprenant un premier compartiment formant un réservoir contenant ledit produit cosmétique, et un second compartiment, en communication sélective ou permanente, avec le premier via au moins un orifice, et destiné à recevoir un organe d'application dudit produit, un élément de fermeture étant apte à obturer une ouverture délimitée par un bord dudit second compartiment, le premier compartiment étant de volume variable, le second compartiment étant de volume fixe, la hauteur axiale H de l'ensemble étant apte à diminuer avec le volume du premier compartiment.According to the invention, these objects are achieved by producing a set of axis X, for packaging and applying a cosmetic product, comprising a first compartment forming a reservoir containing said product cosmetic, and a second compartment, in selective communication or permanent, with the first via at least one orifice, and intended to receive a member for applying said product, a closure element being able to close an opening delimited by an edge of said second compartment, the first compartment being of variable volume, the second compartment being of fixed volume, the axial height H of the assembly being able to decrease with the volume of the first compartment.

Avantageusement, l'élément de fermeture est apte à obturer l'ouverture de manière étanche au moins au produit et de préférence également à l'air.Advantageously, the closing element is able to close the opening of sealing at least the product and preferably also air.

Ainsi, l'organe d'application, entre deux applications, est maintenu de façon étanche à l'intérieur du second logement. Il est donc conservé à l'abri de l'air, ce qui lui permet de conserver ses bonnes propriétés mécaniques, et ce qui permet d'éviter que le produit restant sur l'organe d'application soit altéré en présence d'air ou vienne souiller l'environnement de l'organe d'application.Thus, the application member, between two applications, is maintained so watertight inside the second housing. So it is kept away from air, which allows it to retain its good mechanical properties, and which makes it possible to prevent the product remaining on the applicator member from being altered in presence of air or contaminate the environment of the application member.

La réduction du volume du second compartiment contenant le produit entraíne une surpression à l'intérieur du premier compartiment qui pousse le produit à sortir du premier compartiment, via l'orifice, de manière à venir dans le second compartiment dans lequel se trouve l'organe d'application et ceci, quelle que soit la viscosité du produit.Reducing the volume of the second compartment containing the product leads an overpressure inside the first compartment which pushes the product to exit the first compartment, via the orifice, so as to come into the second compartment in which the applicator member is located, regardless of or the viscosity of the product.

En outre, la hauteur axiale de l'ensemble diminuant avec le volume du second compartiment, l'encombrement de l'ensemble se réduit au fur et à mesure des utilisations. Cela permet notamment de donner une indication à l'utilisateur quant à la quantité de produit restant dans l'ensemble.In addition, the axial height of the assembly decreases with the volume of the second compartment, the overall size of the unit is reduced as and when uses. This allows in particular to give an indication to the user as to the amount of product remaining in the set.

Selon un mode préféré de l'invention, l'ensemble comprend un piston apte à coulisser axialement dans ledit premier compartiment en réponse à une pression exercée sur le second compartiment.According to a preferred embodiment of the invention, the assembly comprises a piston capable of slide axially in said first compartment in response to a pressure on the second compartment.

Selon une première configuration, le piston peut coulisser à l'intérieur du premier compartiment en réponse à une pression exercée sur l'élément de fermeture. Ainsi, l'utilisateur a l'impression d'appuyer sur un bouton poussoir d'un dispositif à pompe classique.According to a first configuration, the piston can slide inside the first compartment in response to pressure exerted on the element of closing. Thus, the user has the impression of pressing a push button of a conventional pump device.

Selon une deuxième configuration, l'ensemble comprend un organe d'actionnement solidaire de la paroi latérale du second compartiment, ledit organe d'actionnement coopérant par filetage avec la paroi externe du premier compartiment, de manière à faire coulisser le piston à l'intérieur du premier compartiment en réponse au vissage dudit organe d'actionnement sur le premier compartiment.According to a second configuration, the assembly includes a member actuation integral with the side wall of the second compartment, said actuator cooperating by threading with the external wall of the first compartment, so that the piston slides inside the first compartment in response to the screwing of said actuating member on the first compartment.

Le piston est par exemple obtenu d'une seule pièce avec la paroi latérale du second compartiment. Alternativement, le piston est solidaire de la paroi latérale du second compartiment, notamment par collage ou enserrage. Le piston présente par exemple un décrochement axial autour duquel est enserré un prolongement de la paroi latérale du second compartiment afin de le maintenir solidaire du second compartiment. Alternativement encore, la paroi latérale et/ou le fond du second compartiment est/sont simplement en appui sur le piston.The piston is for example obtained in one piece with the side wall of the second compartment. Alternatively, the piston is integral with the wall side of the second compartment, in particular by gluing or clamping. The piston has for example an axial recess around which is enclosed an extension of the side wall of the second compartment in order to maintain solidarity with the second compartment. Alternatively again, the wall side and / or the bottom of the second compartment is / are simply supported on the piston.

Avantageusement, la section transversale du piston est sensiblement égale à la section transversale du second compartiment. Ainsi, la force nécessaire à exercer sur le second compartiment pour que le piston s'enfonce dans le premier compartiment est relativement faible du fait que lorsque l'on appuie sur l'élément de fermeture ou bien lorsque l'on actionne l'organe d'actionnement, la force exercée sur le second compartiment est répartie sur l'ensemble de sa périphérie. Cette force est alors transmise au piston également sur l'ensemble de sa périphérie du fait que sa section transversale est sensiblement la même que celle du second compartiment.Advantageously, the cross section of the piston is substantially equal to the cross section of the second compartment. So the force required to exercise on the second compartment so that the piston sinks into the first compartment is relatively small because when you press the closing element or else when the actuating member is actuated, the force exerted on the second compartment is distributed over all of its periphery. This force is then transmitted to the piston also on the assembly from its periphery because its cross section is substantially the same than that of the second compartment.

De préférence, le piston forme une lèvre, apte à coulisser de manière étanche contre une surface interne de la paroi latérale du premier compartiment.Preferably, the piston forms a lip, capable of sliding in leaktight manner against an internal surface of the side wall of the first compartment.

Afin d'éviter tout risque d'ouverture malencontreuse du réservoir de produit, on prévoit avantageusement que l'ensemble de conditionnement comprend un moyen formant butée prévu pour maintenir les premier et second compartiments liés l'un à l'autre.In order to avoid any risk of inadvertent opening of the product tank, we advantageously provides that the packaging assembly includes a stop means provided for holding the first and second compartments linked to each other.

Avantageusement, l'orifice mettant le réservoir de produit en communication avec le second compartiment est obturé par une valve à ouverture unidirectionnelle, notamment un clapet ou une bille, ladite valve s'ouvrant en direction du second compartiment en réponse à une surpression créée à l'intérieur du premier compartiment générée lors de la diminution du volume du premier compartiment. Cette valve permet de mieux doser la quantité de produit qui sort du réservoir. Advantageously, the orifice putting the product reservoir in communication with the second compartment is closed by an opening valve unidirectional, in particular a valve or a ball, said valve opening in direction of the second compartment in response to an overpressure created at the interior of the first compartment generated when the volume of the first compartment. This valve allows better dosing of the amount of product coming out of the tank.

De préférence, l'organe d'application est fixé, notamment collé, soudé ou pincé, sur l'élément de fermeture. L'élément de fermeture peut former un organe de préhension pour l'organe d'application. Il peut être vissé ou encliqueté de manière réversible sur l'ensemble. Alternativement, l'organe d'application peut être fixé, notamment collé, soudé ou pincé, sur une paroi du second compartiment.Preferably, the applicator member is fixed, in particular glued, welded or pinched on the closing element. The closure element may form a gripping member for the application member. It can be screwed or reversibly snapped onto the assembly. Alternatively, the organ application can be fixed, in particular glued, welded or pinched, on a wall of the second compartment.

L'organe d'application est apte à se charger de produit en surface ou en profondeur. Il est constitué au moins en partie d'un matériau poreux. L'organe d'application est par exemple réalisé en un matériau fritté, notamment thermoplastique ou céramique, en feutre, ou en un matériau compressible élastiquement, notamment une mousse à cellules fermées, ouvertes ou semi-ouvertes, ou un élastomère, ou en une superposition de couches d'un ou plusieurs de ces matériaux. Il peut également être constitué d'un matériau plastique semi-rigide qui comporte des micro-aspérités.The applicator member is capable of taking on product on the surface or in depth. It consists at least in part of a porous material. The organ application is for example made of a sintered material, in particular thermoplastic or ceramic, felt, or a compressible material elastically, in particular a closed cell foam, open or semi-open, or an elastomer, or in a superposition of layers of one or many of these materials. It can also be made of a material semi-rigid plastic which has micro-roughness.

Avec de tels matériaux, la restitution du produit sur la surface à traiter se fait, soit par capillarité ou effet de tension superficielle au contact de la peau, soit par expulsion du produit, des pores de l'applicateur, en réponse à une légère déformation (par pression) de celui-ci sur la surface à traiter. L'organe d'application peut être constitué de plusieurs matériaux différents, notamment d'un empilement de mousses présentant des duretés différentes, une partie des mousses pouvant être à cellules ouvertes, le reste étant à cellules fermées.With such materials, the product is returned to the surface to be treated, either by capillarity or surface tension effect in contact with the skin, or by expelling the product, from the pores of the applicator, in response to a slight deformation (by pressure) of the latter on the surface to be treated. The organ application can be made of several different materials, including a stack of foams with different hardnesses, part foams can be open cell, the rest being cell closed.

A titre d'exemple, l'organe d'application est constitué d'une mousse de polyéther, de polyester, de polyuréthanne, de NBR (Acrylonitrile Butadiene Rubber), de SBR (Styrene Butadiene Rubber), de PVC (Chlorure de polyvinyle) ou d'un fritté de polyéthylène, de bronze, de verre, de silicone, ou de Nylon. For example, the applicator member consists of a foam polyether, polyester, polyurethane, NBR (Acrylonitrile Butadiene Rubber), SBR (Styrene Butadiene Rubber), PVC (Polyvinyl Chloride) or a sintered polyethylene, bronze, glass, silicone, or Nylon.

Un applicateur en matériau élastiquement compressible correspond au mode de réalisation préférentiel. En effet, lorsque l'applicateur est compressible élastiquement, la surface d'application, située en regard du ou des orifices via lesquels le produit est amené, peut reculer élastiquement sous la pression du produit, de manière à autoriser un chargement plus important, en surface et/ou en profondeur, de l'applicateur.An applicator made of elastically compressible material corresponds to the mode preferential realization. Indeed, when the applicator is compressible elastically, the application surface, located opposite the orifice (s) via which the product is brought in, can retract elastically under the pressure of the product, so as to allow a larger load, on the surface and / or in depth, from the applicator.

Avantageusement, au moins une partie de la surface de l'organe d'application est recouverte d'un flocage, notamment à base de fibres de rayonne, de coton, de viscose, ou de nylon. Le flocage contribue à créer une réserve de produit, immédiatement au voisinage de la surface d'application. En outre, il permet de conférer plus de douceur à l'application, notamment lorsque l'organe d'application est en mousse à larges cellules. Le flocage peut être constitué d'un mélange de fibres de longueur, et/ou de nature, et/ou de diamètre différents. Alternativement, au moins une partie de la surface de l'organe d'application est recouverte d'un revêtement tissé ou non-tissé.Advantageously, at least part of the surface of the applicator member is covered with a flocking, in particular based on rayon fibers, cotton, viscose, or nylon. Flocking contributes to creating a reserve of product, immediately in the vicinity of the application surface. In addition, it allows give more smoothness to the application, especially when the organ application is in large cell foam. Flocking can be made a mixture of fibers of length, and / or nature, and / or diameter different. Alternatively, at least part of the surface of the organ application is covered with a woven or non-woven coating.

Lorsque l'organe d'application est fixé sur l'élément de fermeture, il est de préférence en contact avec au moins une partie de la paroi interne du second compartiment, notamment avec le fond du second compartiment. La paroi transversale inférieure du second compartiment destinée à recevoir l'organe d'application, dans laquelle est ménagé l'orifice, a alors avantageusement une forme sensiblement complémentaire de la forme de l'organe d'application, de manière à ce que l'organe d'application puisse, notamment en position fermée de l'ensemble, venir en contact intime, voire élastique, avec cette portion de surface, et se charger parfaitement en produit. L'organe d'application peut par exemple avoir un profil convexe ou encore un profil concave. Il peut également avoir une section transversale circulaire, triangulaire, carrée ou de toute autre forme.When the applicator member is fixed to the closure element, it is preferably in contact with at least part of the inner wall of the second compartment, in particular with the bottom of the second compartment. Wall lower cross section of the second compartment intended to receive the organ application, in which the orifice is formed, then advantageously has a shape substantially complementary to the shape of the applicator member, so that the applicator member can, in particular in the closed position of the whole, come into intimate, even elastic, contact with this portion of surface, and load perfectly with product. The implementing body may by example have a convex profile or a concave profile. He can also have a circular, triangular, square or any other cross section form.

Dans le cas d'un organe d'application en matériau compressible élastiquement, notamment en mousse, l'organe d'application peut être dimensionné par rapport au second logement de sorte que, en position montée à l'intérieur du second logement, il ne soit pas comprimé axialement de façon sensible. Le recul mentionné ci-avant s'en trouve facilité, en raison de la moindre résistance offerte par l'applicateur.In the case of an application member made of elastically compressible material, in particular in foam, the applicator member can be sized by relative to the second housing so that, in the mounted position inside the second housing, it is not compressed axially significantly. The recoil mentioned above is facilitated, due to the lower resistance offered by the applicator.

Toutefois, selon une alternative, il est possible de prévoir que l'organe d'application soit en partie comprimé axialement à l'intérieur du logement qui le contient de sorte que, à l'ouverture de l'élément de fermeture dont il est solidaire, le produit situé au voisinage de la surface de l'organe d'application soit pompé en profondeur à l'intérieur de ce dernier en réponse à la décompression de la mousse. Ce mode de réalisation est plus adapté à des compositions de faible viscosité.However, according to an alternative, it is possible to provide that the organ application is partly compressed axially inside the housing which contains so that upon opening the closure member of which it is integral, the product located near the surface of the applicator member be pumped deep inside the latter in response to the decompression of the foam. This embodiment is more suitable for low viscosity compositions.

L'ensemble selon l'invention est particulièrement adapté pour le conditionnement et la distribution d'un produit cosmétique sous forme d'un liquide, d'un gel ou d'une crème. Cet ensemble, en raison notamment du mode de distribution qui le caractérise, est particulièrement adapté à la distribution de produits à forte viscosité tels que certains produits capillaires, de soin, ou de maquillage.The assembly according to the invention is particularly suitable for packaging and distribution of a cosmetic product in the form of a liquid, gel or cream. This set, in particular due to the mode which characterizes it, is particularly suitable for distribution products with high viscosity such as certain hair products, care products, or of makeup.

Selon un autre aspect de l'invention, on prévoit que le réservoir de produit fermé par un piston constitue une recharge, indépendante du reste de l'ensemble, sur laquelle peut se monter le second logement contenant l'applicateur.According to another aspect of the invention, it is expected that the product reservoir closed by a piston constitutes a refill, independent of the rest of the assembly, on which can be mounted the second housing containing the applicator.

L'ensemble 10 représenté aux figures 1 à 3 est formé d'un réservoir 20 de produit P sur lequel est monté un logement 30 pour un applicateur 50. L'applicateur 50 est solidaire d'un capot 60 prévu pour fermer de façon étanche le logement 30. Le réservoir 20 et le logement 30 de l'applicateur 50 communiquent via une ouverture 40 qui permet le passage du produit provenant du réservoir dans le logement. L'ensemble 10 a une hauteur axiale H qui diminue au fur et à mesure des utilisations.The assembly 10 shown in Figures 1 to 3 is formed of a reservoir 20 of product P on which is mounted a housing 30 for an applicator 50. The applicator 50 is integral with a cover 60 provided for sealingly closing the housing 30. The reservoir 20 and the housing 30 of the applicator 50 communicate via an opening 40 which allows the passage of the product from the tank into the housing. The assembly 10 has an axial height H which decreases with use.

Le réservoir 20, réalisé par exemple en polypropylène, est de forme cylindrique de révolution et d'axe longitudinal X. Le réservoir 20 comprend une paroi latérale 21 dont une première extrémité 22 est ouverte, et dont une seconde extrémité, opposée à la première, est fermée par un fond 23, lequel, pour des raisons qui seront expliquées dans la suite de la description, présente un renfoncement 230 vers l'intérieur du réservoir. La surface interne de la paroi latérale 21 comporte deux bourrelets 24 diamétralement opposés disposés à l'extrémité supérieure 22 ouverte. Ces bourrelets 24 coopèrent avec l'élément formant le logement 30 d'une façon qui sera détaillée ultérieurement.The reservoir 20, made for example of polypropylene, is of cylindrical shape of revolution and of longitudinal axis X. The reservoir 20 comprises a wall lateral 21 of which a first end 22 is open, and of which a second end, opposite to the first, is closed by a bottom 23, which, for reasons which will be explained in the following description, presents a recess 230 towards the interior of the tank. The inner surface of the wall side 21 has two diametrically opposite beads 24 arranged at the upper end 22 open. These beads 24 cooperate with the element forming the housing 30 in a manner which will be detailed later.

Le logement 30 est également réalisé en polypropylène. Il est également de forme cylindrique et d'axe longitudinal X. Il est défini par une paroi latérale 33 formée d'une seule pièce avec un fond 36, en forme hémisphérique, dans lequel débouche une extrémité du passage 40. La paroi latérale 33 se prolonge au-delà du fond 36, par une jupe 34 dont une extrémité est destinée à venir se loger dans le réservoir 20. La surface extérieure de la paroi latérale 33 et de son prolongement 34 comporte deux rainures longitudinales 330. Les rainures 330 sont prévues pour recevoir les bourrelets 24 du réservoir. Les rainures ne s'étendent pas sur toute la hauteur axiale de la surface extérieure de la paroi latérale du second compartiment. Ainsi, une portion 38 de la paroi 33 située en dessous de la rainure 330 forme une butée pour le bourrelet 24 de manière à maintenir liés entre eux le réservoir 20 et le logement 30 de l'applicateur 50 et empêcher l'ouverture du réservoir. Le logement 30 peut alors coulisser dans le réservoir de préférence sans frottement avec la paroi interne du réservoir. Le logement 30 est monté dans le réservoir par exemple par encliquetage.The housing 30 is also made of polypropylene. It is also cylindrical shape with a longitudinal axis X. It is defined by a side wall 33 formed in one piece with a bottom 36, in hemispherical shape, in which opens one end of the passage 40. The side wall 33 extends beyond the bottom 36, by a skirt 34, one end of which is intended to come lodge in the tank 20. The external surface of the side wall 33 and of its extension 34 comprises two longitudinal grooves 330. The grooves 330 are provided to receive the beads 24 from the tank. The grooves do not do not extend over the entire axial height of the outer surface of the wall side of the second compartment. Thus, a portion 38 of the wall 33 located in below the groove 330 forms a stop for the bead 24 so as to keep linked the reservoir 20 and the housing 30 of the applicator 50 and prevent the tank from opening. The housing 30 can then slide in the tank preferably without friction with the internal wall of the tank. The housing 30 is mounted in the tank, for example by snap-fastening.

L'extrémité supérieure du logement 30, opposée au fond 36, forme un bord libre 32 délimitant une ouverture 31. La surface extérieure du logement 30 comporte à cette extrémité un filetage 35 destiné à coopérer avec un filetage correspondant 61 prévu sur la surface interne d'une jupe 62 du bouchon 60. Le bouchon 60 comprend en outre une jupe d'étanchéité 63 prévue pour venir se loger sur la surface interne de la paroi latérale 33 du logement 30. En position fermée du bouchon, le logement 30 est parfaitement étanche.The upper end of the housing 30, opposite the bottom 36, forms an edge free 32 delimiting an opening 31. The external surface of the housing 30 has at this end a thread 35 intended to cooperate with a thread corresponding 61 provided on the internal surface of a skirt 62 of the plug 60. The cap 60 further comprises a sealing skirt 63 provided to come lodge on the internal surface of the side wall 33 of the housing 30. In position closed from the cap, the housing 30 is perfectly sealed.

Le bouchon 60 est solidaire d'un applicateur 50 sous forme d'un bloc d'une mousse à cellules ouvertes, conformé de manière correspondante au profil hémisphérique défini par le fond 36 du logement 30. La surface de l'applicateur 50 est recouverte d'un revêtement de flocage 51. L'applicateur 50 est collé sur le capuchon 60. The plug 60 is integral with an applicator 50 in the form of a block of a open cell foam, shaped accordingly to the profile hemispherical defined by the bottom 36 of the housing 30. The surface of the applicator 50 is covered with a flock coating 51. The applicator 50 is bonded to the cap 60.

L'applicateur 50 est dimensionné par rapport au logement 30 de sorte que, en position fermée du bouchon 60, une portion au moins de la surface d'application de l'applicateur 50 soit au contact du fond 36 dans lequel débouche l'ouverture 40. Dans cette position toutefois, l'applicateur 50 n'est pas comprimé axialement de façon sensible.The applicator 50 is dimensioned relative to the housing 30 so that, in closed position of plug 60, at least a portion of the surface of application of the applicator 50 is in contact with the bottom 36 in which opens the opening 40. In this position, however, the applicator 50 is not not axially sensibly compressed.

Un piston 80, s'étendant sur sensiblement toute la section transversale du réservoir, forme une lèvre d'étanchéité 81 prévue pour coulisser sur la surface interne de la paroi latérale 21 du réservoir. Le piston 80 a, sensiblement vers sa périphérie, une portion axiale 82 qui s'étend vers l'intérieur du réservoir. La jupe 34 du logement 20 est clipsée autour du de la portion axiale 82 de manière à maintenir le piston solidaire du logement 30.A piston 80, extending over substantially the entire cross section of the reservoir, forms a sealing lip 81 intended to slide on the surface internal side wall 21 of the tank. The piston 80 has, substantially towards its periphery, an axial portion 82 which extends towards the inside of the tank. The skirt 34 of the housing 20 is clipped around the of the axial portion 82 of so as to keep the piston integral with the housing 30.

L'ouverture 40 permettant le passage du produit est définie dans le piston 80. Une valve 70 réalisée en matériau élastomère est montée dans l'ouverture 40. Il s'agit d'une valve unidirectionnelle qui ne s'ouvre que lorsqu'une surpression est créée dans le réservoir 20. Cette valve 70 comprend une portion plane 71 capable de fermer de façon étanche l'ouverture 40 et disposée du côté de l'ouverture située vers le fond 36 du logement 30, et trois pattes 72 déformables élastiquement, disposées de l'autre côté de l'ouverture 40, vers le réservoir 20. La portion plane 71 et les pattes 72 sont reliées par une tige 73 montée à l'intérieur de l'ouverture. En position de repos, la portion plane 71 repose sur le piston 80, sur l'ensemble de la périphérie délimitant l'ouverture. Lorsqu'une surpression est créée à l'intérieur du réservoir, les pattes 72 se déforment légèrement de manière telle que la tige 73 remonte dans l'ouverture et la portion plane 71 se décolle du piston.The opening 40 allowing the passage of the product is defined in the piston 80. A valve 70 made of elastomeric material is mounted in the opening 40. It is a one-way valve that opens only when an overpressure is created in the reservoir 20. This valve 70 comprises a flat portion 71 capable of sealingly closing the opening 40 and disposed on the side of the opening located towards the bottom 36 of the housing 30, and three tabs 72 elastically deformable, arranged on the other side of the opening 40, towards the reservoir 20. The flat portion 71 and the legs 72 are connected by a rod 73 mounted inside the opening. In the rest position, the flat portion 71 rests on the piston 80, on the entire periphery delimiting the opening. When an overpressure is created inside the tank, the tabs 72 are slightly deform so that the rod 73 goes back into the opening and the flat portion 71 comes off the piston.

Pour utiliser le dispositif, l'utilisateur appuie sur le bouchon 60, comme sur un bouton-poussoir, lorsque celui-ci est en position fermée sur le logement 30. La force exercée sur le bouchon 60 est transmise au piston 80 par l'intermédiaire de la paroi formant le logement 30 qui est solidaire du piston. La lèvre 81 du piston coulisse le long de la paroi latérale 21 du réservoir de sorte que le satellite formé par le bouchon 60, l'applicateur 50 et son logement 30 ainsi que le piston 80, s'enfonce dans le réservoir 20 comme on l'a représenté à la figure 3. Une surpression est alors créée à l'intérieur du réservoir 20 qui entraíne l'ouverture de la valve 70. Une dose de produit est poussée hors du réservoir vers l'applicateur 50 via l'orifice 40 ouvert. La dose de produit est pompée par la mousse. Le volume de produit évacué du réservoir permet de rétablir la pression à l'intérieur de celui-ci de sorte que la valve se referme. L'utilisateur peut ensuite ouvrir le bouchon et appliquer le produit chargé dans l'applicateur sur la surface à traiter. Lors de l'enfoncement du satellite dans le réservoir, les saillies 22 se déplacent dans les rainures 330 de manière à éviter tout mouvement relatif de rotation du réservoir par rapport au satellite.To use the device, the user presses the plug 60, as on a push button, when the latter is in the closed position on the housing 30. The force exerted on the plug 60 is transmitted to the piston 80 via of the wall forming the housing 30 which is integral with the piston. Lip 81 of piston slides along the side wall 21 of the tank so that the satellite formed by the plug 60, the applicator 50 and its housing 30 as well as the piston 80 sinks into the reservoir 20 as shown in the Figure 3. An overpressure is then created inside the tank 20 which causes the valve 70 to open. A dose of product is pushed out of the reservoir to the applicator 50 via the open port 40. The dose of product is pumped by foam. The volume of product evacuated from the tank allows restore the pressure inside it so that the valve closes. The user can then open the cap and apply the product loaded in the applicator on the surface to be treated. When the satellite is inserted into the tank, the projections 22 move in the grooves 330 so as to avoid any relative movement of rotation of the reservoir with respect to the satellite.

L'utilisateur peut ensuite refermer de manière étanche le dispositif et recommencer l'opération pour une seconde utilisation. Il est à noter que sensiblement tout le produit contenu dans le réservoir peut être utilisé, étant donné que le fond du récipient 23 a une forme sensiblement complémentaire de celle du piston, notamment grâce à la présence du renfoncement 230 formé dans le fond 23 du réservoir.The user can then tightly close the device and repeat the operation for a second use. It is to highlight that substantially all of the product in the tank can be used, being given that the bottom of the container 23 has a substantially complementary shape that of the piston, in particular thanks to the presence of the recess 230 formed in the bottom 23 of the tank.

Le mode de réalisation représenté à la figure 4 diffère de celui qui vient d'être décrit en conformité avec les figures 1 à 3 en ce que le piston 80 ne présente pas de portion axiale mais s'étend sur toute la section transversale du réservoir 20. Le fond 23 du réservoir est alors une simple paroi transversale sans renfoncement. De même, la paroi latérale 33 du logement 30 ne se prolonge pas au-delà du fond 36.The embodiment represented in FIG. 4 differs from that which has just been described in accordance with Figures 1 to 3 in that the piston 80 does not have no axial portion but extends over the entire cross section of the tank 20. The bottom 23 of the tank is then a simple transverse wall without recess. Similarly, the side wall 33 of the housing 30 does not extend not beyond the bottom 36.

Selon ce mode de réalisation, le piston est solidaire du logement 30 par collage de la surface supérieure du piston sur la surface inférieure du fond du logement 30. Alternativement, le fond du logement peut être simplement en appui sur le piston. According to this embodiment, the piston is secured to the housing 30 by bonding of the upper surface of the piston on the lower surface of the bottom of the housing 30. Alternatively, the bottom of the housing can be simply support on the piston.

Le mode de réalisation représenté à la figure 5 diffère de celui décrit en conformité avec les figures 1 à 3 en ce que le piston 80 est formé d'une seule pièce avec la paroi formant le logement 30. La lèvre 81 qui coulisse dans le réservoir 20 est formée à la périphérie du prolongement 34 de la paroi latérale 33 du logement 30.The embodiment shown in FIG. 5 differs from that described in compliance with Figures 1 to 3 in that the piston 80 is formed of a single part with the wall forming the housing 30. The lip 81 which slides in the tank 20 is formed at the periphery of the extension 34 of the side wall 33 of housing 30.

Selon ce mode de réalisation, l'ouverture 40 est formée directement dans le fond 36 du logement 30.According to this embodiment, the opening 40 is formed directly in the bottom 36 of housing 30.

Selon une variante non représentée de ce mode de réalisation, on peut prévoir que la paroi latérale 33 du logement 30 n'est pas prolongée d'une jupe 34, de la même manière que dans le mode de réalisation représenté à la figure 4. La lèvre est alors formée à la périphérie du fond 36 du logement. Le fond 23 du réservoir est une simple paroi transversale sans renfoncement.According to a variant not shown of this embodiment, one can provide that the side wall 33 of the housing 30 is not extended by a skirt 34, the same way as in the embodiment shown in Figure 4. The lip is then formed at the periphery of the bottom 36 of the housing. The bottom 23 of tank is a simple transverse wall without recess.

Le mode de réalisation représenté à la figure 6 diffère de celui décrit en conformité avec les figures 1 à 3 en ce qu'il comprend un organe d'actionnement 90 distinct du capot 60.The embodiment shown in FIG. 6 differs from that described in compliance with Figures 1 to 3 in that it comprises a member actuation 90 separate from the cover 60.

Il s'agit d'une bague annulaire dont la surface interne présente un filetage 91 qui coopère avec un filetage complémentaire 24 prévu sur la surface externe de la paroi latérale 21 du réservoir 20. Une protubérance annulaire 92 s'étend vers l'intérieur de la bague annulaire 90 et vient se loger dans une cavité 37 complémentaire prévue sur la surface externe de la paroi latérale 33 du logement.It is an annular ring whose internal surface has a thread 91 which cooperates with a complementary thread 24 provided on the external surface of the side wall 21 of the reservoir 20. An annular protuberance 92 extends towards the inside of the annular ring 90 and is housed in a cavity 37 complementary provided on the external surface of the side wall 33 of the housing.

Ainsi, le vissage de la bague annulaire 90 sur le réservoir 20 entraíne l'enfoncement du satellite dans le réservoir 20.Thus, the screwing of the annular ring 90 on the reservoir 20 causes the insertion of the satellite into the reservoir 20.

Selon ce mode de réalisation, on peut prévoir que le réservoir 30 rempli du produit et dans lequel est monté le piston, pourvu ou non d'une valve, constitue une recharge. Cette recharge, indépendante du reste de l'ensemble, est recouverte d'un film protecteur qui est par exemple thermoscellé sur la surface externe du piston afin de fermer de façon étanche l'ouverture 40. Ainsi, une fois qu'un premier réservoir de produit est vide, l'utilisateur le retire du reste de l'ensemble et monte une nouvelle recharge après avoir retiré le film protecteur.According to this embodiment, provision can be made for the reservoir 30 filled with the product and in which the piston is mounted, with or without a valve, constitutes A reload. This refill, independent of the rest of the set, is covered with a protective film which is for example heat sealed on the surface external piston in order to seal the opening 40. Thus, once a first product tank is empty, the user removes it from the rest of the assembly and assembles a new refill after removing the protective film.

Le mode de réalisation illustré sur les figures 7 et 8 diffère de celui décrit en conformité avec les figures 1 à 3 principalement en ce que l'applicateur 50 n'est pas solidaire du capot 60 mais du fond 36 du logement 30. Le fond 36 du logement 30 est une surface plane sur laquelle est collé l'applicateur 50.The embodiment illustrated in FIGS. 7 and 8 differs from that described in compliance with Figures 1 to 3 mainly in that the applicator 50 is not integral with the cover 60 but with the bottom 36 of the housing 30. The bottom 36 of the housing 30 is a flat surface on which the applicator 50 is bonded.

Selon ce mode de réalisation, l'ouverture 40 permettant le passage du produit provenant du réservoir 20 dans le logement est cette fois définie par une cheminée axiale 84, formée d'une seule pièce, avec le piston 80 depuis laquelle elle s'étend jusqu'à une extrémité libre 85, située à l'intérieur du logement 30.According to this embodiment, the opening 40 allowing the passage of the product coming from the reservoir 20 in the housing is this time defined by a axial chimney 84, formed in one piece, with the piston 80 from which it extends to a free end 85, located inside the housing 30.

L'applicateur 50 est monté à l'intérieur du logement 30 autour de la cheminée 84. L'applicateur 50 présente une première extrémité 51 collée sur le fond 36 du logement 30 et une seconde extrémité 52, opposée à la première, qui constitue une surface d'application en forme de dôme. Lorsque l'applicateur 50 est monté dans le logement 30, il occupe sensiblement tout le logement, l'applicateur ayant une forme sensiblement complémentaire de la forme du logement. L'applicateur 50 présente notamment un évidement axial 53 dont la forme est choisie de façon que l'applicateur vienne en appui sur la paroi de la cheminée, sans être sensiblement comprimé latéralement par ladite cheminée. En position détendue de l'applicateur représentée à la figure 8, l'évidement axial 53 a une hauteur axiale sensiblement plus grande que la hauteur axiale de la cheminée 84 de manière à définir une cavité interne 54 au-dessus de l'extrémité libre 85 de la cheminée. La cavité 54 constitue ainsi une réserve de produit à proximité de la surface d'application, le produit provenant du réservoir ne pouvant venir au contact de l'applicateur que dans la cavité. Pour augmenter le débit de distribution du produit vers la surface d'application, une fente axiale 55 traverse avantageusement l'applicateur, dans l'axe X, depuis la cavité 54 jusqu'à la surface d'application 52. La largeur de cette fente peut varier en fonction de la viscosité du produit et du débit souhaité.The applicator 50 is mounted inside the housing 30 around the chimney 84. The applicator 50 has a first end 51 glued to the bottom 36 of the housing 30 and a second end 52, opposite the first, which constitutes a dome-shaped application surface. When the applicator 50 is mounted in the housing 30, it occupies substantially the entire housing, the applicator having a shape substantially complementary to the shape of the housing. The applicator 50 has in particular an axial recess 53, the shape is chosen so that the applicator comes to rest on the wall of the chimney, without being substantially compressed laterally by said chimney. In the relaxed position of the applicator shown in FIG. 8, the recess axial 53 has an axial height appreciably greater than the axial height of the chimney 84 so as to define an internal cavity 54 above the free end 85 of the chimney. The cavity 54 thus constitutes a reserve of product near the application surface, the product from the tank can only come into contact with the applicator in the cavity. For increase the product delivery rate to the application surface, a axial slot 55 advantageously passes through the applicator, in the X axis, from the cavity 54 up to the application surface 52. The width of this slot can vary depending on the viscosity of the product and the desired flow rate.

Lorsque l'utilisateur appuie sur le bouchon 60, le satellite formé par le bouchon 60, l'applicateur 50 et son logement 30 ainsi que le piston 80, s'enfonce dans le réservoir 20 créant une surpression à l'intérieur du réservoir 20. La surpression entraíne alors le produit à l'intérieur de la cheminée 84. L'utilisateur peut alors ouvrir le bouchon de sorte que l'applicateur 50 se détend, comme on l'a représenté à la figure 8, et la surface d'application 52 émerge du logement 30. La décompression de l'applicateur provoque la formation de la cavité 54 et l'aspiration du produit dans la cavité 54 ainsi qu'un pompage du produit dans les cellules de la mousse situées à proximité de la cavité 54. La portion de l'applicateur située entre la cavité 54 et la surface d'application 52 est alors saturée en produit. L'utilisateur peut alors, en tenant le réservoir 20, appliquer la surface d'application sur la zone à traiter.When the user presses the plug 60, the satellite formed by the plug 60, the applicator 50 and its housing 30 as well as the piston 80, is inserted into the tank 20 creating an overpressure inside the tank 20. The overpressure then causes the product inside the chimney 84. The user can then open the cap so that the applicator 50 is relaxes, as shown in FIG. 8, and the application surface 52 emerges from the housing 30. The decompression of the applicator causes the formation of the cavity 54 and the aspiration of the product into the cavity 54 as well as a pumping the product into the foam cells located near the cavity 54. The portion of the applicator located between cavity 54 and the surface of application 52 is then saturated with product. The user can then, taking the reservoir 20, apply the application surface to the area to be treated.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. It is obvious that there are variations be made without departing from the spirit of the invention as claimed below.

En particulier, la forme de l'applicateur peut être différente de la forme illustrée en référence aux modes de réalisation qui viennent d'être décrits. D'une façon générale, la forme de l'applicateur est choisie en fonction de la zone à traiter. Par exemple, dans le cas d'un applicateur pour les lèvres, on utilisera par exemple un applicateur sensiblement en forme de cône.In particular, the shape of the applicator may be different from the shape illustrated with reference to the embodiments which have just been described. In a manner Generally, the shape of the applicator is chosen according to the area to be treated. For example, in the case of a lip applicator, we will use example an applicator substantially cone-shaped.
