Description

La présente demande a pour objet un dispositif de conditionnement, notamment pour produit de maquillage. L'invention est particulièrement adapté aux produits pulvérulents, pâteux, ou sous forme d'un gel. A titre d'exemple, on peut utiliser le conditionnement selon l'invention pour un blush, un fond de teint, un fard à joues, etc..The present application relates to a packaging device, in particular for makeup product. The invention is particularly suitable for products powdery, pasty, or in the form of a gel. As an example, we can use the packaging according to the invention for a blush, a foundation, a blush, etc.

Les produits de maquillage qui sont destinés à être fréquemment utilisés sont généralement conditionnés dans des boítiers ou des pots de petite dimensions, sur lesquels on s'efforce de prévoir des couvercles à verrouillage simple qui soient pratique à utiliser.Makeup products that are intended to be used frequently are generally packaged in small boxes or pots, on which efforts are made to provide simple locking covers which are convenient to use.

Pour éviter que les produits de maquillage ne se dégradent, au contact de l'air ambiant, il est nécessaire que ces boítiers ou ces pots présentent une bonne étanchéité à l'air.To prevent makeup products from degrading on contact with air ambient, it is necessary that these boxes or these pots have a good air tightness.

Cette étanchéité n'est cependant pas toujours suffisante, notamment en raison de l'usure que subit le mécanisme de verrouillage du couvercle qui est fréquemment utilisé.This tightness is however not always sufficient, in particular due to wear and tear on the lid locking mechanism which is frequently used.

Le brevet français 2 412 474 décrit un récipient ou boítier, dont le compartiment où est placé le produit, est obturé de façon étanche au moyen d'une ventouse qui adhère étroitement contre une paroi qui entoure le compartiment. La ventouse peut être solidaire, en sa partie centrale, de la face intérieure du couvercle, et est apte à venir s'appliquer, en position de fermeture du couvercle, sur une portée plane autour du compartiment. Des moyens sont prévus pour supprimer, à l'ouverture, l'effet de ventouse. Lors de la fermeture du boítier, de l'air est enfermé entre la surface libre du produit et la ventouse. Cet espace permet un dégagement de solvant, qui sera de plus en plus important au fur et à mesure que le niveau de produit diminuera dans le réceptacle.French patent 2,412,474 describes a container or case, the compartment of which where the product is placed, is sealed with a suction cup which adheres tightly against a wall that surrounds the compartment. The suction cup may be integral, in its central part, with the inner face of the cover, and is able to be applied, in the closed position of the cover, on a surface hovers around the compartment. Means are provided to remove, at the opening, the suction cup effect. When the case is closed, air is trapped between the free surface of the product and the suction cup. This space allows a release of solvent, which will become more and more important as the product level will decrease in the receptacle.

Selon d'autres systèmes connus, l'étanchéité est assurée au moyen d'une lèvre ménagée dans le couvercle, et apte à coopérer de manière étanche avec une rainure prévue dans le fond du boítier, tout autour du compartiment.According to other known systems, the seal is ensured by means of a lip formed in the cover, and able to cooperate in sealed manner with a groove provided in the bottom of the case, all around the compartment.

Pour tous ces systèmes, la conservation des produits à l'utilisation est précaire, car il se crée à l'utilisation, une chambre d'air située au dessus du produit, qui permet à celui-ci de se décharger de son (ou de ses) solvant(s), d'une quantité qui est fonction de l'espace situé entre le couvercle et le produit. A chaque ouverture, une quantité importante de solvant s'échappe ainsi, et limite dans le temps, la conservation et la qualité du produit. L'espace étant de plus en plus grand au fil des utilisations, la perte en solvant est donc de plus en plus importante. Typiquement, le solvant peut être de l'eau (jusqu'à environ 20%), de l'isoparafine, du silicone, etc.. Le produit peut comporter un mélange de plusieurs solvants.For all these systems, the conservation of products for use is precarious, because it creates during use, an air chamber located above the product, which allows the latter to discharge its (or its) solvent (s), an amount which is a function of the space between the cover and the product. At each opening, a large amount of solvent thus escapes, and limits the time, the shelf life and product quality. The space is getting bigger and bigger uses, the loss of solvent is therefore more and more important. Typically, the solvent can be water (up to about 20%), isoparafine, silicone, etc. The product may contain a mixture of several solvents.

Aussi, est-ce un des objets de la présente invention que de fournir un dispositif de conditionnement d'un produit pulvérulent, pâteux, ou sous forme d'un gel, dans lequel, l'évaporation du (ou des) solvant(s) entrant dans sa composition est sensiblement réduite, en comparaison des systèmes discutés précédemment.It is therefore an object of the present invention to provide a device for packaging of a pulverulent, pasty product, or in the form of a gel, in which, the evaporation of the solvent (s) entering into its composition is significantly reduced compared to the systems discussed above.

C'est un autre objet de l'invention que d'assurer une bonne étanchéité durant sensiblement toute la durée de vie du produit.It is another object of the invention to ensure a good seal during substantially the entire life of the product.

D'autres objets de la présente invention apparaítront de manière détaillée dans la description qui suit.Other objects of the present invention will appear in detail in the description which follows.

Selon l'invention, ces objets sont atteints au moyen d'un dispositif de conditionnement, notamment de produit de maquillage comprenant un corps présentant une cavité débouchant à sa partie supérieure et formant un logement pour le produit conditionné et un couvercle apte à recouvrir de manière amovible ledit corps, ledit produit présentant une surface libre pour le prélèvement du produit, caractérisé en ce qu'il comprend au moins un élément élastiquement déformable monté de sorte que, en position fermée du couvercle sur le corps, ladite surface libre soit en appui élastique contre un élément de protection recouvrant sensiblement toute ladite surface libre, ledit élément de protection étant imperméable à au moins un solvant présent dans le produit. L'élément de protection peut être constitué par exemple, d'un film de polyéthylène, de polypropylène, d'un complexe polyéthylène téréphtalate/Aluminium/polyéthylène, etc..According to the invention, these objects are achieved by means of a device for packaging, in particular of make-up product comprising a body having a cavity opening at its upper part and forming a housing for the packaged product and a cover capable of removably covering said body, said product having a free surface for the removal of product, characterized in that it comprises at least one elastically element deformable mounted so that, in the closed position of the cover on the body, said free surface is in elastic abutment against a protective element covering substantially all of said free surface, said protective element being impermeable to at least one solvent present in the product. The element of protection can consist for example of a polyethylene film, polypropylene, of a polyethylene terephthalate / aluminum / polyethylene complex, etc.

L'élément de protection peut être au contact de la surface libre du produit via un tamis fixe axialement, le fond du logement comportant un piston maintenant le produit au contact du tamis, un fond souple permettant d'exercer une pression sur le piston de manière à permettre la sortie du produit au travers du tamis. Le tamis peut être constitué d'un matériau tissé ou non tissé, d'une grille, d'un film ou d'une surface perforée, ou d'une association de tels éléments.The protective element can be in contact with the free surface of the product via a sieve fixed axially, the bottom of the housing comprising a piston holding the produced in contact with the sieve, a flexible bottom allowing to exert pressure on the piston so as to allow the product to exit through the screen. The sieve can be made of a woven or non-woven material, a grid, a film or a perforated surface, or a combination of such elements.

Avantageusement, l'élément de protection est constitué d'un élément plan monté sur le couvercle au moyen d'un mécanisme à ressort. Le mécanisme à ressort peut être constitué d'un ressort hélicoïdal.Advantageously, the protective element consists of a planar element mounted on the cover by means of a spring mechanism. The spring mechanism may consist of a coil spring.

Selon une alternative, l'élément de protection est monté sur un bloc de mousse élastique solidaire du couvercle.According to an alternative, the protective element is mounted on a block of foam elastic secured to the cover.

L'élément de protection peut être sous forme d'une mousse à cellules fermées, dont l'épaisseur et l'élasticité sont choisies de sorte que la mousse soit en appui sur la surface libre du produit quelque soit le niveau de remplissage du produit dans la cavité. A titre indicatif, il peut s'agir d'une mousse de polyéthylène, SBR (synthetic butadiène rubber), ou une mousse de chlorure de polyvinyle (PVC).The protective element may be in the form of a closed cell foam, whose thickness and elasticity are chosen so that the foam is supported on the free surface of the product whatever the level of filling of the product in the cavity. As an indication, it can be a polyethylene foam, SBR (synthetic butadiene rubber), or polyvinyl chloride (PVC) foam.

Avantageusement, on dispose entre l'élément de protection et le couvercle, un élément (un élastomère ou un feutre par exemple) imbibé d'au moins un solvant entrant dans la composition du produit conditionné, de manière à maintenir le produit en atmosphère chargé dudit solvant.Advantageously, there is between the protective element and the cover, a element (an elastomer or a felt for example) soaked in at least one solvent entering into the composition of the packaged product, so as to maintain the produced in an atmosphere charged with said solvent.

Selon une autre alternative, le produit repose sur un élément élastiquement déformable, monté dans le fond de la cavité, la surface libre du produit étant, en position fermée du couvercle sur le corps, en appui élastique contre ledit élément de protection.According to another alternative, the product rests on an elastically element deformable, mounted in the bottom of the cavity, the free surface of the product being, in closed position of the cover on the body, in elastic support against said element protection.

De préférence, le dispositif se présente sous forme d'un boítier dont le couvercle est monté articulé sur le corps autour d'un axe d'articulation, des moyens de fermeture étant disposés à l'opposé de l'axe d'articulation, pour verrouiller le couvercle en position fermée sur le corps.Preferably, the device is in the form of a housing whose cover is mounted articulated on the body about an articulation axis, means of closure being arranged opposite the hinge pin, to lock the cover in closed position on the body.

Le dispositif peut comprendre en plus des moyens aptes à assurer une étanchéité à la périphérie de la cavité. Avantageusement, de tels moyens comportent une jupe ou une lèvre, formée sur la face interne du couvercle, et apte à coopérer avec une rainure correspondante ménagée dans le corps tout autour de la cavité.The device may also comprise means capable of ensuring a seal at the periphery of the cavity. Advantageously, such means include a skirt or lip, formed on the inner face of the cover, and able to cooperate with a corresponding groove made in the body all around the cavity.

L'élément élastiquement déformable, l'élément de protection, les moyens d'étanchéité à la périphérie de la cavité peuvent être constitués d'une seule pièce, ce qui contribue à réduire de manière substantielle le coût de fabrication du boítier.The elastically deformable element, the protection element, the means sealing at the periphery of the cavity can be made in one piece, which contributes to a substantial reduction in the cost of manufacturing the housing.

Le produit conditionné peut être, à titre d'exemple, un blush, un fond de teint, un fard à joues, etc..The packaged product can be, for example, a blush, a foundation, a blush, etc.

A titre d'exemple, on utilise une feuille de polyéthylène (PE), de polypropylène (PP), ou un complexe de polyéthylène téréphtalate/Aluminium/polyéthylène. Le couvercle 7 comporte autour de l'évidement 13, une lèvre ou jupe 16 apte, en position fermée du couvercle 7 sur le fond 2, à s'insérer de manière étanche dans une rainure 17 ménagée dans le fond du boítier tout autour de l'évidement 3. Ces moyens permettent de renforcer l'étanchéité du conditionnement du produit 4.The conditioning device 1 shown in FIGS. 1A-1C is presented under shape of a case of type, make-up case, comprising a bottom 2 defining a first hollow compartment 3 for receiving the product 4 in the form powdery, pasty, or in the form of a gel. Background 2 defines a second recess 5 in which is disposed an applicator, such as a powder puff foam 6. On the bottom 2, is hinged a cover 7, around an axis of articulation 8. The cover 7 comprises a clasp 9 able to cooperate with a member complementary 10 carried by the bottom of the case, in order to lock the cover in closed position on the bottom 2. The cover has a recess 11, located substantially opposite the recess 5, and in the bottom of which is mounted (by example by gluing) a mirror 12. The cover has a second recess 13 which, in the closed position of the cover 7 on the bottom 2, is opposite the recess 3 in which the product is disposed 4. Inside the recess 13 a protective element 14 is mounted by means of a mechanism spring 15, such as a helical spring. Spring 15 can be mounted in the bottom of the recess 13, for example, by gluing or by clicking. The element of protection 14 is mounted on the free end of the spring, for example, by gluing. Alternatively, the spring and the protective element can form a single piece, obtained by molding. The protective element is in the form of a generally planar element, such as a sheet of waterproof material solvent (s) present in product formula 4. Protection element 14 is dimensioned so as to cover substantially all of the free surface 18 of the product 4. As an example, a sheet of polyethylene (PE), of polypropylene (PP), or a polyethylene complex terephthalate / Aluminum / polyethylene. The cover 7 has around the recess 13, a lip or skirt 16 capable, in the closed position of the cover 7 on the bottom 2, to be inserted in a sealed manner in a groove 17 formed in the bottom of the housing all around the recess 3. These means make it possible to reinforce sealing the product packaging 4.

Ainsi, dans la position fermée illustrée à la figure 1A, le ressort maintient en appui élastique la feuille d'étanchéité 14 sur le produit 4. La feuille recouvre sensiblement toute la surface libre 18 du produit 4, et ralentit considérablement l'évaporation.Thus, in the closed position illustrated in FIG. 1A, the spring keeps in support elastic the sealing sheet 14 on the product 4. The sheet covers substantially the entire free surface 18 of the product 4, and slows down considerably evaporation.

En position ouverte, représentée à la figure 1B, le ressort est en position de repos. Le produit peut être prélevé au moyen de la houppette 6.In the open position, shown in FIG. 1B, the spring is in the position of rest. The product can be picked up using the puff 6.

Dans la position fermée illustrée à la figure 1C, le niveau de produit 4 dans le compartiment 3 a baissé au fil des utilisations. La feuille d'étanchéité 14 est toujours en appui élastique sur la surface libre 18 du produit. La longueur et l'élasticité du ressort sont en effet choisies de manière à ce que, quelque soit le niveau de remplissage du produit 4 dans le boítier, la feuille d'étanchéité soit toujours en appui sur la surface libre du produit. Ainsi, par cet arrangement, il n'existe sensiblement aucune chambre d'air entre le produit et le couvercle, lorsque celui-ci est en position fermée sur le fond 2, et ce, pendant toute la durée de vie du produit. Le solvant ne peut donc pas s'échapper du produit. La conservation et la qualité du produit sont parfaites tout au long de la durée de vie du produit.In the closed position illustrated in FIG. 1C, the level of product 4 in the compartment 3 has dropped over use. The sealing sheet 14 is always in elastic support on the free surface 18 of the product. The length and the elasticity of the spring are in fact chosen so that, whatever the filling level of product 4 in the housing, the sealing sheet is always resting on the free surface of the product. So by this arrangement he there is essentially no air chamber between the product and the cover, when the latter is in the closed position on the bottom 2, for the entire duration life of the product. The solvent therefore cannot escape from the product. The conservation and product quality are perfect throughout their lifespan of the product.

Dans le mode de réalisation de la figure 2, le ressort 15 et la feuille de protection 14 sont remplacés par un bloc 20 d'un matériau déformable élastiquement. Sa fonction est de maintenir en appui permanent, sur la surface libre 18 du produit 4, en position fermée du couvercle 7 sur le fond 2, une surface étanche au(x) solvant(s) entrant dans la composition du produit. A cet effet, on utilise un bloc de mousse à cellules fermées imperméable au solvant entrant dans la composition du produit conditionné. L'épaisseur et l'élasticité de la mousse sont choisies de sorte que la mousse soit en appui élastique sur la surface libre du produit, pendant sensiblement toute la durée de vie du produit. Le bloc de mousse 20 peut être collé sur le couvercle 7. A titre d'exemple, on utilise une mousse à cellules fermées telle qu'une mousse de polyéthylène, de SBR (synthetic butadiène rubber), ou de chlorure de polyvinyle (PVC). D'autres matériaux encore peuvent être utilisés. Ainsi, au fil des utilisations, la mousse se détend d'une hauteur sensiblement égale à la hauteur de produit prélevé, pour rester en appui élastique sur la surface libre 18. De la même manière que pour le mode de réalisation des figures 1A-1C, l'étanchéité est renforcée au moyen d'un arrangement lèvre 16/rainure 17, situé tout autour du produit.In the embodiment of Figure 2, the spring 15 and the protective sheet 14 are replaced by a block 20 of an elastically deformable material. Her function is to maintain permanent support on the free surface 18 of the product 4, in the closed position of the cover 7 on the bottom 2, a surface sealed against (x) solvent (s) used in the composition of the product. For this purpose, a block of closed cell foam impermeable to the solvent used in the composition of the packaged product. The thickness and elasticity of the foam are chosen from so that the foam is in elastic support on the free surface of the product, for substantially the entire life of the product. The foam block 20 can be glued to the cover 7. As an example, cell foam is used closed such as polyethylene foam, SBR (synthetic butadiene) rubber), or polyvinyl chloride (PVC). Still other materials can be used. Thus, over use, the foam relaxes from a height substantially equal to the height of product removed, to remain in elastic support on the free surface 18. In the same way as for the embodiment of the Figures 1A-1C, the tightness is reinforced by means of a lip arrangement 16 / groove 17, located all around the product.

Dans le mode de réalisation de la figure 3, on réalise sous forme d'une seule pièce (obtenue par exemple par moulage de polyéthylène ou de polypropylène) un élément 21 ayant plusieurs fonctions. L'élément 21 définit en sa périphérie une partie annulaire formant saillie 22, apte à coopérer de manière étanche avec la rainure 17 prévue dans le fond du boítier. L'élément 21 comporte par ailleurs une partie annulaire intermédiaire 23, formant un soufflet élastique, dont l'extrémité libre est reliée à une portion plane 24, apte à recouvrir de manière sensiblement étanche toute la surface libre 18 du produit 4. La longueur et l'élasticité du soufflet sont choisies de sorte que, en position fermée du couvercle sur le fond, la portion plane 24 soit en permanence, en appui élastique sur la surface libre 18 du produit. Le soufflet 23 est séparé de la partie 22 par une paroi 25 orientée de manière opposée à la saillie 22, et dont le diamètre externe est légèrement inférieur au diamètre interne de l'évidement 13, de manière à être insérée à force dans ledit évidement 13. Alternativement, l'élément 21 peut être monté dans l'évidement 13, par collage, claquage, ou par soudure. Cet arrangement est particulièrement avantageux en ce qu'il permet de réduire de manière substantielle le coût de fabrication du dispositif selon la présente invention Par ailleurs, il n'y a pas de rupture d'étanchéité entre l'élément de protection sur le produit et l'étanchéité à la périphérie du boítier.In the embodiment of Figure 3, it is carried out as a single part (obtained for example by molding of polyethylene or polypropylene) an element 21 having several functions. Element 21 defines at its periphery a annular portion forming projection 22, capable of cooperating in leaktight manner with the groove 17 provided in the bottom of the housing. Element 21 also includes a intermediate annular part 23, forming an elastic bellows, the end of which free is connected to a flat portion 24, capable of covering substantially waterproof the entire free surface 18 of the product 4. The length and elasticity of the bellows are chosen so that, in the closed position of the cover on the bottom, the portion plane 24 is permanently, in elastic support on the free surface 18 of the product. The bellows 23 is separated from the part 22 by a wall 25 oriented so opposite the projection 22, and whose external diameter is slightly less than the internal diameter of the recess 13, so as to be forced into said recess 13. Alternatively, the element 21 can be mounted in the recess 13, by gluing, snapping, or by welding. This arrangement is particularly advantageous in that it allows the cost of manufacturing the device according to the present invention Furthermore, there is no seal between the protective element on the product and the seal against periphery of the case.

Dans le mode de réalisation de la figure 4A, le ressort des figures 1A-1C est remplacé par un bloc de mousse 30 dont une face est collée sur le fond de l'évidement 13. L'autre face du bloc de mousse 30 est collée sur une face correspondante de la feuille d'étanchéité 14. Le bloc de mousse peut être constitué de cellules, fermées, ouvertes, ou semi ouvertes. Cette configuration permet à l'élément 14 de mieux épouser la forme de la surface libre du produit au fil des utilisations. En effet, au fil des utilisations, la surface libre du produit forme généralement, en raison du mode de prélèvement du produit, un léger creux en sa partie centrale.In the embodiment of FIG. 4A, the spring of FIGS. 1A-1C is replaced by a block of foam 30, one face of which is glued to the bottom of the recess 13. The other side of the foam block 30 is glued to one side corresponding to the sealing sheet 14. The foam block can be consisting of cells, closed, open, or semi open. This configuration allows element 14 to better conform to the shape of the free surface of the product at thread of uses. Indeed, over use, the free surface of the product forms generally, due to the method of sampling the product, a slight dip in its central part.

Le mode de réalisation de la figure 4B diffère de celui de la figure 4A en ce qu'un élément 31, saturé d'un solvant entrant dans la composition du produit 4, est inséré entre le couvercle 7 et le bloc de mousse 30. A titre d'exemple, l'élément 31 est constitué d'une couche de feutre, d'élastomère, ou d'un gel. Un passage est ménagé entre le bord de l'élément 31 et le bord interne de l'évidement 13 de manière à permettre un dégagement de solvant dans l'espace compris entre le fond 2 et le couvercle 7, et délimité par les moyens d'étanchéité périphérique 16, 17. Ainsi, en position fermée du couvercle 7, le produit est maintenu en atmosphère chargé de solvant, ce qui améliore encore la conservation et la qualité du produit tout au long de sa durée de vie.The embodiment of Figure 4B differs from that of Figure 4A in that a element 31, saturated with a solvent used in the composition of product 4, is inserted between the cover 7 and the foam block 30. For example, the element 31 consists of a layer of felt, elastomer, or gel. A passage is formed between the edge of the element 31 and the internal edge of the recess 13 of so as to allow solvent to escape into the space between the bottom 2 and the cover 7, and delimited by the peripheral sealing means 16, 17. Thus, in the closed position of the cover 7, the product is kept in solvent-laden atmosphere, which further improves storage and product quality throughout its lifespan.

Dans le mode de réalisation des figures 5A et 5B, le produit est disposé dans le fond du compartiment 3 par l'intermédiaire d'un organe élastiquement déformable tel qu'un ressort 40 dont l'élasticité et la longueur sont choisies de manière à maintenir en appui élastique la surface libre 18 du produit 4 contre le couvercle 7, ou contre une feuille de protection 14 portée par le couvercle, et ce, quelque soit le niveau de remplissage de la cavité 3 (sensiblement pleine, avec le ressort 40 compressé, tel que montré à la figure 5A, ou à moitié vide, avec le ressort 40 partiellement compressé, tel que représenté à la figure 5B). La feuille de protection peut être collée sur la face interne du couvercle. De préférence, le produit 4 est monté sur le ressort 40 par l'intermédiaire d'un plateau ou d'une cupule 41. De la même manière que pour les modes de réalisation précédents, le ressort peut être remplacé par un bloc de mousse, à cellules, fermées, ouvertes, ou semi ouvertes.In the embodiment of FIGS. 5A and 5B, the product is placed in the bottom of compartment 3 via an elastically deformable member such as a spring 40 whose elasticity and length are chosen so as to keep the free surface 18 of the product 4 in elastic support against the cover 7, or against a protective sheet 14 carried by the cover, whatever the filling level of the cavity 3 (substantially full, with the spring 40 compressed, as shown in Figure 5A, or half empty, with spring 40 partially compressed, as shown in Figure 5B). The sheet of protection can be stuck on the inside of the cover. Preferably, the product 4 is mounted on the spring 40 by means of a plate or a cup 41. In the same way as for the previous embodiments, the spring can be replaced by a foam block, with cells, closed, open, or semi open.

Selon une autre alternative non représentée, il est possible d'envisager de monter d'une part l'élément de protection 14 sur le couvercle 7 par l'intermédiaire d'un premier élément élastiquement déformable (ressort, mousse, etc.), et d'autre part, de monter le produit dans le fond du compartiment 3 par l'intermédiaire d'un second élément élastiquement déformable (ressort mousse, etc.). Une telle configuration améliore encore la mise en appui de la surface libre 18 du produit 4 sur la feuille d'étanchéité, et limite l'échappement de solvant entre deux utilisations du produit 4.According to another alternative not shown, it is possible to consider mounting firstly the protective element 14 on the cover 7 by means of a first elastically deformable element (spring, foam, etc.), and secondly, to mount the product in the bottom of compartment 3 via a second elastically deformable element (foam spring, etc.). Such a configuration further improves the support of the free surface 18 of the product 4 on the sealing sheet, and limits the escape of solvent between two product uses 4.

Ainsi, avec le dispositif selon l'invention, on réalise un système de tampon élastique indépendant de l'étanchéité du couvercle, qui permet un contact intime entre la surface libre du produit et l'élément de protection 14, ce qui ralentit très sensiblement le degré d'évaporation du ou des solvants contenus dans le produit 4. Au fur et à mesure de l'usure du produit, l'élément 14 reste en contact quasi-étanche avec la surface du produit, en épousant sa forme.Thus, with the device according to the invention, a buffer system is produced. elastic independent of the tightness of the cover, which allows an intimate contact between the free surface of the product and the protective element 14, which slows down very appreciably the degree of evaporation of the solvent (s) contained in the product 4. As the product wears down, the element 14 remains in almost leaktight contact with the surface of the product, matching its shape.

Dans le mode de réalisation de la figure 6, le produit 4 est monté dans une coupelle amovible 51 dont le fond 50 forme un piston suiveur, de manière à former une chambre à volume variable. La coupelle comporte une jupe rigide 52 dont l'ouverture définie par son bord inférieur est obturée par une membrane souple 53 en élastomère thermoplastique. La membrane souple 53 présente une configuration et une élasticité telles que le piston est toujours en contact avec le produit 4 contenu dans la coupelle, lequel produit est en contact d'un tamis fixe axialement 55, qui va maintenant être discuté plus en détail. In the embodiment of FIG. 6, the product 4 is mounted in a removable cup 51, the bottom 50 of which forms a follower piston, so as to form a variable volume chamber. The cup has a rigid skirt 52 the opening defined by its lower edge is closed by a membrane flexible 53 made of thermoplastic elastomer. The flexible membrane 53 has a configuration and elasticity such that the piston is always in contact with the product 4 contained in the dish, which product is in contact with a fixed sieve axially 55, which will now be discussed in more detail.

A la différence des autres modes de réalisation, la surface 14, étanche au solvant de la formule, est maintenue au contact de la surface libre 18 du produit 4, via un tamis fixe 55, monté sur le bord supérieur de la coupelle 51. Dans ce mode de réalisation, le bloc de mousse 15 dont une surface 14 est étanche au solvant du produit 4, comporte un bourrelet périphérique 56 apte, en position fermée du couvercle 7, à s'insérer dans une gorge annulaire 57 ménagée dans une pièce annulaire disposée sur la paroi supérieure du corps 2 du boítier. Le bloc de mousse 15 est collé sur la face interne du couvercle 7. D'autres moyens encore peuvent être prévus pour renforcer l'étanchéité annulaire autour de la coupelle. A titre d'exemple, un joint en matériau élastomérique pourrait être surinjecté sur le bord libre de la coupelle.Unlike the other embodiments, the surface 14, impervious to solvent of the formula, is kept in contact with the free surface 18 of the product 4, via a fixed screen 55, mounted on the upper edge of the cup 51. In this mode of embodiment, the block of foam 15, a surface 14 of which is impermeable to the solvent of the product 4, has a suitable peripheral bead 56, in the closed position of the cover 7, to be inserted in an annular groove 57 formed in a room annular disposed on the upper wall of the body 2 of the housing. The block of foam 15 is bonded to the inner face of the cover 7. Still other means may be provided to reinforce the annular seal around the cup. AT For example, a seal made of elastomeric material could be over-injected on the free edge of the cup.

De la même manière que pour les autres modes de réalisation, au fil des utilisations, le produit est maintenu par le piston 50 au contact du tamis dont sensiblement toute la surface, en position fermée du couvercle 7, est en contact intime avec la face 14 du bloc de mousse 15, interdisant ainsi la présence de poche d'air au dessus du produit. En position fermée, le piston maintient seulement le produit en contact avec le tamis, sans toutefois exercer de pression apte à forcer le produit à sortir au travers des orifices du tamis 55. Lors de l'utilisation du produit 4, la sortie de celui-ci au travers des orifices du tamis 55 est réalisée en exerçant une pression sur le fond souple 53 du boítier. Le produit est ensuite prélevé sur la surface du tamis, soit avec les doigts, soit avec un applicateur traditionnel en mousse, contenu dans un autre emplacement du boítier. Ce mode de réalisation est particulièrement adapté au conditionnement de produits à forte concentration en solvant, par exemple en eau.In the same way as for the other embodiments, over the uses, the product is held by the piston 50 in contact with the sieve, substantially the entire surface, in the closed position of the cover 7, is in contact intimate with the face 14 of the foam block 15, thus prohibiting the presence of air pocket above the product. In the closed position, the piston maintains only the product in contact with the sieve, without exerting pressure able to force the product out through the holes in the screen 55. When the use of product 4, the output thereof through the openings of the screen 55 is performed by exerting pressure on the flexible bottom 53 of the housing. The product is then taken from the surface of the sieve, either with your fingers or with a traditional foam applicator, contained in another location in the housing. This embodiment is particularly suitable for the packaging of products with a high concentration of solvent, for example in water.

Exemple de réalisation :Example of realization:

On réalise un boítier dont l'épaisseur maximum de produit dans la cavité 3 est de 5 mm. Le produit est un fard à joues contenant jusqu'à 20% d'eau. L'élément élastiquement déformable est un bloc de mousse à cellules ouvertes ou semi ouvertes, et dont l'épaisseur est de l'ordre de 8 mm. Une face du bloc de mousse est collée sur la surface interne du couvercle. Sur l'autre face du bloc de mousse, on colle un film de polyéthylène dont l'épaisseur est de l'ordre de 0,5 mm.We make a housing whose maximum product thickness in the cavity 3 is 5 mm. The product is a blush containing up to 20% water. The element elastically deformable is a block of open cell foam or semi open, and whose thickness is of the order of 8 mm. One side of the foam block is glued to the inner surface of the cover. On the other side of the foam block, a polyethylene film is bonded, the thickness of which is around 0.5 mm.

Par ailleurs, des essais ont été réalisés avec des boítiers de section circulaire et des boítiers de section carrée. Sur le produit contenu, sous forme d'un cake, à l'intérieur de ces boítiers, on monte une pellicule de polypropylène de 200 µm. Le solvant contenu dans le produit est de l'eau. Les boítiers ont été mis en étuve à 45° pendant 24 heures. Des boítiers sans pellicule ont également été placés dans l'étuve. Dans le cas des boítiers de forme circulaire, la perte en poids est de 55 % pour les boítiers ne présentant pas la pellicule, et seulement 31 % pour les boítiers selon l'invention. Dans le cas des boítiers de section carrée, la perte en poids est de 31,3 % pour les boítiers ne présentant pas la pellicule, et seulement 12,3 % pour les boítiers selon l'invention. L'amélioration est dons sensible, quelle que soit la forme du boítier.In addition, tests have been carried out with circular cross-section boxes and square section boxes. On the product contained, in the form of a cake, to inside these boxes, a 200 µm polypropylene film is mounted. The solvent in the product is water. The housings were put in an oven at 45 ° for 24 hours. Casings without film were also placed in the oven. In the case of circular shaped boxes, the weight loss is 55% for boxes without film, and only 31% for housings according to the invention. In the case of square section boxes, the loss in weight is 31.3% for the cases without the film, and only 12.3% for the boxes according to the invention. Improvement is noticeable donation, what whatever the shape of the case.
