Description

La présente invention concerne un dispositif pour le nettoyage du corps, en particulier un récipient qui est destiné à contenir un produit cosmétique et qui comporte un élément exfoliant.The present invention relates to a device for cleaning the body, in particular a container which is intended to contain a cosmetic product and which comprises an exfoliating element.

Afin d'enlever les cellules mortes de la peau, on utilise de façon courante des produits cosmétiques contenant des particules exfoliantes comme par exemple de la poudre de polyéthylène, de fines particules de quartz ou de coques de noix, ou encore des produits desquamants qui ont une action biologique sur la peau. Toutefois, de tels produits cosmétiques sont vendus sans applicateur si bien que les utilisateurs se voient obligés d'utiliser un gant de toilette traditionnel, une éponge ou encore leurs mains pour appliquer le produit. Alternativement, il est également connu d'utiliser des gants, par exemple des gants de crin, pour exfolier la peau.In order to remove dead cells from the skin, cosmetic products containing exfoliating particles such as, for example, polyethylene powder, fine quartz particles or nut shells, or desquamating products which have a biological action on the skin. However, such cosmetics are sold without an applicator so that users are forced to use a traditional washcloth, a sponge or their hands to apply the product. Alternatively, it is also known to use gloves, for example horsehair gloves, to exfoliate the skin.

Le brevet US 5,504,963 décrit un dispositif pour exfolier la peau du dos, le dispositif comprenant un filet formé par des cordons entrelacés les uns dans les autres. La demande de brevet US2003/0208871 décrit également un filet.The US Patent 5,504,963 discloses a device for exfoliating the skin of the back, the device comprising a net formed by cords intertwined with each other. The patent application US2003 / 0208871 also describes a net.

La demande de brevet US 2003/0208871 décrit une éponge pour exfolier et laver la peau pouvant être associée à divers dispositifs contenant un produit à appliquer sur la peau.The patent application US 2003/0208871 describes a sponge for exfoliating and washing the skin that can be combined with various devices containing a product to be applied to the skin.

Le brevet US 5 558 453 décrit un récipient pouvant contenir du savon ou tout autre produit de soins, sur lequel est fixé par encliquetage une brosse on un coussinet abrasif destiné à être utilisé conjointement avec le produit contenu dans le récipient.The U.S. Patent 5,558,453 discloses a container that may contain soap or other care product, on which is fixed by snapping a brush or an abrasive pad for use together with the product contained in the container.

Le brevet DE 2 017 009 décrit un récipient pouvant contenir par exemple de la mousse à raser, de l'huile de massage ou encore une crème solaire, le récipient étant surmonté d'une mousse d'application au niveau du conduit de sortie du produit.The DE 2,017,009 describes a container that may contain for example shaving foam, massage oil or sunscreen, the container being surmounted by an application foam at the product outlet duct.

Il existe un besoin pour réaliser un dispositif pour exfolier la peau qui soit simple et économique à réaliser.There is a need to achieve a device for exfoliating the skin that is simple and economical to achieve.

Il existe également un besoin pour réaliser un dispositif qui ait un pouvoir exfoliant similaire à celui d'un gant de crin sans qu'il soit nécessaire d'ajouter un produit exfoliant.There is also a need to make a device that has an exfoliant power similar to that of a horsehair glove without the need to add an exfoliating product.

Il existe également un besoin pour réaliser un dispositif qui soit pratique à utiliser.There is also a need to make a device that is convenient to use.

Selon l'un de ses aspects, l'invention a pour objet un récipient pour un produit cosmétique tel que défini dans la revendication 1.According to one of its aspects, the subject of the invention is a container for a cosmetic product as defined in claim 1.

L'élément abrasif peut présenter un pouvoir abrasif compris entre 0.01 et 0,02 g/cm2/min, bornes incluses.The abrasive element may have an abrasive power of between 0.01 and 0.02 g / cm 2 / min, inclusive.

L'élément abrasif étant sur la surface externe du récipient ou de l'applicateur, il peut être utilisé en particulier lorsque le récipient est fermé. Le corps du récipient ou l'organe de fermeture sert ainsi de poignée pour appliquer l'élément abrasif sur la peau ce qui permet d'exfolier la peau de manière très pratique et très efficace.Since the abrasive element is on the outer surface of the container or applicator, it can be used in particular when the container is closed. The body of the container or the closure member thus serves as a handle for applying the abrasive element to the skin, which makes it possible to exfoliate the skin in a very practical and very effective manner.

L'élément abrasif a un pouvoir abrasif qui lui permet d'exfolier la peau, c'est-à-dire qu'il permet d'enlever au moins en partie les cellules mortes de la surface de la peau en le déplaçant sur la peau.The abrasive element has an abrasive power that allows it to exfoliate the skin, i.e. it removes at least a part of the dead cells from the surface of the skin by moving it on the skin .

Le pouvoir abrasif de l'élément abrasif correspond à la quantité de plâtre enlevée par minute, par un centimètre carré d'une surface abrasive appliquée sur un carreau de plâtre d'épaisseur 50 mm avec une ponceuse Black & Decker CD400 135W, la pression exercée sur le carreau de plâtre résultant du poids de la ponceuse dont, seul le mouvement dans le plan de la surface abrasive est contraint.The abrasive power of the abrasive element corresponds to the amount of plaster removed per minute, one square centimeter of an abrasive surface applied to a 50 mm thick plaster tile with a Black & Decker CD400 135W sander, the pressure exerted on the plaster tile resulting from the weight of the sander, of which only the movement in the plane of the abrasive surface is constrained.

L'élément abrasif peut comporter un matériau alvéolaire comportant une pluralité d'alvéoles s'ouvrant sur la face externe via au moins un bord débouchant.The abrasive element may comprise a cellular material having a plurality of cells opening on the outer face via at least one emerging edge.

Le matériau alvéolaire peut être une mousse, notamment une mousse à cellules fermées. La mousse peut être une mousse d'un matériau thermoplastique, notamment d'une polyoléfine telle qu'un polyéthylène ou un polypropylène. La mousse peut avoir une densité inférieure à 70 kg/m3, ou inférieure à 40 kg/m3. En utilisant une mousse pour réaliser l'élément abrasif, on obtient un élément exfoliant à faible coût.The cellular material may be a foam, in particular a closed-cell foam. The foam may be a foam of a thermoplastic material, in particular a polyolefin such as polyethylene or polypropylene. The foam may have a density of less than 70 kg / m 3 , or less than 40 kg / m 3 . By using a foam to make the abrasive element, a low cost exfoliating element is obtained.

L'élément abrasif peut avoir une épaisseur supérieure ou égale à 1 mm, notamment comprise entre 4 mm et 5 cm, bornes incluses.The abrasive element may have a thickness greater than or equal to 1 mm, in particular between 4 mm and 5 cm, including terminals.

L'élément abrasif peut comporter des passages débouchant, d'une part, sur la face externe de l'élément abrasif et, d'autre part, à l'intérieur du corps.The abrasive element may comprise passages opening on the one hand, on the outer face of the abrasive element and, on the other hand, inside the body.

L'élément abrasif peut être situé sur une paroi latérale du corps. Alternativement, l'élément abrasif peut être situé sur une paroi supérieure de l'organe de fermeture.The abrasive element may be located on a side wall of the body. Alternatively, the abrasive element may be located on an upper wall of the closure member.

L'élément abrasif peut par exemple être collé ou soudé sur le corps ou sur l'organe de fermeture.The abrasive element may for example be glued or welded to the body or the closure member.

Le corps peut comporter des parois déformables, notamment élastiquement déformables.The body may comprise deformable walls, in particular elastically deformable.

Le récipient peut être sous forme d'un tube, d'un pot ou d'un flacon.The container may be in the form of a tube, a pot or a bottle.

Le récipient peut contenir un produit cosmétique, notamment un produit lavant. Le récipient pourrait également contenir un produit exfoliant ou un produit desquamant.The container may contain a cosmetic product, especially a washing product. The container could also contain an exfoliating product or a desquamating product.

Le récipient peut contenir un produit sous forme de gel, de crème ou de mousse.The container may contain a product in the form of a gel, cream or mousse.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé pour réaliser un récipient tel qu'il vient d'être décrit, qui comporte les étapes suivantes :

  • disposer un élément abrasif dans un moule ;
  • disposer une préforme présentant une ouverture dans le moule,
  • déformer en exerçant une pression interne sur la préforme afin de lui faire épouser sensiblement la forme d'une surface intérieure du moule et de l'élément abrasif.
The invention further relates, in another of its aspects, to a method for producing a container as just described, which comprises the following steps:
  • arranging an abrasive element in a mold;
  • have a preform having an opening in the mold,
  • deforming by exerting an internal pressure on the preform in order to make it substantially conform to the shape of an inner surface of the mold and the abrasive element.

En mettant l'élément abrasif dans le moule, on réalise ainsi de façon simple et peu onéreuse un récipient qui sert à la fois à contenir un produit et qui permet d'exfolier la peau. Le procédé ne nécessite en effet pas d'étape supplémentaire par rapport à un procédé de fabrication du récipient seul.By putting the abrasive element into the mold, a container that serves both to contain a product and to exfoliate the skin is thus easily and inexpensively made. The process does not require any additional step compared to a manufacturing process of the container alone.

La préforme, qui peut être réalisée par injection ou par extrusion, peut être déformée par soufflage.The preform, which can be made by injection or extrusion, can be deformed by blowing.

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

La paroi latérale 22 du corps comporte deux grandes faces relativement planes, ces faces étant reliées par deux bords arrondis comportant des concavités 25 permettant de recevoir les doigts de l'utilisateur pour faciliter la préhension du récipient. La paroi latérale 22 est en outre élastiquement déformable pour faciliter la sortie du produit.The bottle 10 comprises a body 20, of generally rectangular shape, having a side wall 22 of substantially elliptical cross section and a bottom 23, substantially flat. The side wall 22 of the body has two large relatively flat faces, these faces being connected by two rounded edges having concavities 25 for receiving the fingers of the user to facilitate gripping of the container. The side wall 22 is further elastically deformable to facilitate the exit of the product.

A l'opposé du fond 23, le corps 20 comporte un col 24, réalisé d'un seul tenant avec le reste du corps. Le col 24 définit une ouverture 21 par laquelle le produit peut sortir. Le corps du flacon est par exemple réalisé en polyéthylène.In contrast to the bottom 23, the body 20 has a neck 24, made in one piece with the rest of the body. The neck 24 defines an opening 21 through which the product can exit. The body of the bottle is for example made of polyethylene.

L'ouverture 21 du corps du flacon peut être obturée par une capsule de fermeture 30 agencée pour s'encliqueter sur le col 24. La capsule 30 comporte une jupe de fixation, non visible sur les figures, qui est fixée sur le col 24 par des moyens de fixation comportant par exemple une gorge agencée pour recevoir un relief tel qu'un bourrelet annulaire 26 prévu sur le col 24. Alternativement, la capsule pourrait être vissée sur le col du flacon.The opening 21 of the body of the bottle can be closed by a closure cap 30 arranged to snap on the neck 24. The capsule 30 has a fixing skirt, not visible in the figures, which is fixed on the neck 24 by fastening means comprising for example a groove arranged to receive a relief such as an annular bead 26 provided on the neck 24. Alternatively, the capsule could be screwed onto the neck of the bottle.

La capsule comporte en outre une jupe d'habillage 31 qui poursuit le contour du corps de manière à obtenir un flacon de forme générale sensiblement rectangulaire.The capsule further comprises a skirt of dressing 31 which continues the contour of the body so as to obtain a bottle of generally rectangular shape.

La jupe d'habillage 31 se raccorde dans sa partie supérieure à une paroi transversale, non représentée, qui comporte un orifice destiné à être en regard de l'ouverture 21 du col du flacon lorsque la capsule est fixée sur le flacon.The skirt of dressing 31 is connected in its upper part to a transverse wall, not shown, which has an orifice intended to be opposite the opening 21 of the neck of the bottle when the capsule is fixed on the bottle.

La capsule 30 comporte également une casquette 32 articulée sur la jupe d'habillage 31 et destinée à obturer l'orifice.The capsule 30 also comprises a cap 32 articulated on the dressing skirt 31 and intended to close the orifice.

Selon l'invention, le corps 20 comporte, sur sa surface extérieure, un élément abrasif 40 prévu pour exfolier la peau. Selon un exemple particulier, l'élément abrasif 40 comporte un matériau alvéolaire, notamment une mousse à cellules fermées de polyéthylène non réticulé. La mousse a par exemple une densité comprise entre 25 et 65 kg/m3, notamment environ égale à 35 kg/m3.According to the invention, the body 20 comprises, on its outer surface, an abrasive element 40 provided for exfoliating the skin. In a particular example, the abrasive element 40 comprises a cellular material, in particular a closed-cell foam of uncrosslinked polyethylene. The foam has for example a density of between 25 and 65 kg / m 3 , in particular approximately equal to 35 kg / m 3 .

Comme on le voit plus en détail à la figure 2, l'élément abrasif 40 comporte une pluralité d'alvéoles 41 s'ouvrant sur sa face externe via au moins un bord débouchant 42. Une telle configuration permet de délimiter une surface relativement abrasive.As can be seen in more detail at figure 2 , the abrasive element 40 comprises a plurality of cells 41 opening on its outer face via at least one open edge 42. Such a configuration makes it possible to define a relatively abrasive surface.

On choisira la densité de la mousse en fonction du pouvoir exfoliant que l'on souhaite obtenir. En effet, pour un même matériau, plus la mousse est dense, plus les alvéoles sont petits et donc, plus on a de bords débouchants 42 et plus la mousse est exfoliante.We will choose the density of the foam according to the exfoliating power that we want to obtain. Indeed, for the same material, the more the foam is dense, the smaller the cells are and therefore, the more edges 42 are open and the foam is exfoliating.

L'élément abrasif présente un pouvoir abrasif compris entre 0,01 et 0,02 g/cm2/min, bornes incluses.The abrasive element has an abrasive power of between 0.01 and 0.02 g / cm 2 / min, inclusive.

Pour effectuer cette mesure, on applique une surface abrasive d'environ 166,5 cm2 (9 cm × 18,5cm) sur un carreau de plâtre d'épaisseur 50 mm avec une ponceuse Black & Decker CD400 135W, la pression exercée sur le carreau de plâtre résultant du poids de la ponceuse dont, seul le mouvement dans le plan de la surface abrasive est contraint, pendant une durée déterminée. On mesure ensuite la quantité de plâtre enlevée du carreau de plâtre pendant cette durée.To perform this measurement, an abrasive surface of approximately 166.5 cm 2 (9 cm × 18.5 cm) is applied to a 50 mm thick plaster tile with a Black & Decker CD400 135W sander, the pressure exerted on the plaster tile resulting from the weight of the sander, of which only the movement in the plane of the abrasive surface is constrained for a specified period. The amount of plaster removed from the plaster tile is then measured during this time.

Selon cette méthode, on a mesuré le pouvoir abrasif de la mousse à cellules fermées de polyéthylène non réticulé, de densité égale à 35 kg/m3, le pouvoir abrasif étant égal à 0,015 g/cm2/min. A titre comparatif, cette mesure de pouvoir abrasif a été effectuée pour d'autres éléments dans les mêmes conditions. Les résultats obtenus sont les suivants : pour un papier de verre n°0, on obtient un pouvoir abrasif égal à 0,014 g/cm2/min et pour un papier de verre n°2, on obtient un pouvoir abrasif égal à 0,018 g/cm2/min. Pour une mousse douce PTZ® ou Plastazote® (mousse de polyéthylène réticulé basse densité) de densité 45 kg/m3, on obtient un pouvoir abrasif égal à 0,001 g/cm2/min.According to this method, the abrasive power of the non-crosslinked polyethylene closed cell foam with a density of 35 kg / m 3 was measured, the abrasive power being equal to 0.015 g / cm 2 / min. For comparison, this measurement of abrasive power was performed for other elements under the same conditions. The results obtained are as follows: for a sandpaper No. 0, an abrasive power of 0.014 g / cm 2 / min is obtained and for a # 2 sandpaper, an abrasive power of 0.018 g / cm 2 / min. For a soft foam PTZ® or Plastazote® (low density cross-linked polyethylene foam) with a density of 45 kg / m3, an abrasive power of 0.001 g / cm 2 / min is obtained.

L'élément abrasif 40 est par exemple situé sur une des grandes faces sensiblement planes de la paroi latérale 22 du corps du flacon. L'élément abrasif a par exemple la forme d'une plaque sensiblement rectangulaire, d'épaisseur environ égale à 7 mm.The abrasive element 40 is for example located on one of the large substantially plane faces of the side wall 22 of the body of the flask. The abrasive element has for example the form of a substantially rectangular plate, of thickness approximately equal to 7 mm.

Bien entendu, l'élément abrasif peut avoir toute autre forme adaptée à la surface du flacon sur laquelle elle est fixée et aussi à la surface à exfolier.Of course, the abrasive element may have any other shape adapted to the surface of the bottle to which it is attached and also to the surface to be exfoliated.

L'élément abrasif peut par exemple être une plaque ovale, en goutte d'eau ou encore sous forme de fleur.The abrasive element may for example be an oval plate, in drop of water or in the form of a flower.

On pourrait en variante prévoir, sur chacune des grandes faces de la paroi latérale 22, un élément abrasif, les deux éléments abrasif pouvant être identiques ou différents. Lorsque les deux éléments abrasifs sont différents, on choisit de préférence des mousses ayant un pouvoir exfoliant différent de manière à permettre à l'utilisateur de choisir un gommage plus ou moins doux.One could alternatively provide, on each of the large faces of the side wall 22, an abrasive element, the two abrasive elements may be identical or different. When the two abrasive elements are different, it is preferable to choose foams having a different exfoliating power so as to allow the user to choose a more or less gentle scrub.

Le flacon 10 peut être réalisé par exemple de la manière suivante.The bottle 10 can be made for example as follows.

On réalise tout d'abord par extrusion la mousse de polyéthylène en mélangeant du polyéthylène et de l'isobutane pour obtenir un bloc de mousse avec des alvéoles contenant l'isobutane. Ce bloc de mousse est ensuite stocké pour être dégazé de manière à ce que l'air ambiant remplace l'isobutane dans les alvéoles. Pendant le dégazage, le polyéthylène polymérise pour former les cellules fermées de la mousse qui sont alors relativement rigides. Le bloc de mousse ainsi obtenu est lisse en surface à cause de la présence d'une peau qui s'est formée sur les parois du moule d'extrusion. Ce bloc de mousse est ensuite coupé de manière à obtenir au moins une face avec des alvéoles coupés, cette face étant destinée à former la surface exfoliante de l'élément abrasif.The polyethylene foam is first extruded by mixing polyethylene and isobutane to obtain a block of foam with cells containing isobutane. This block of foam is then stored to be degassed so that the ambient air replaces the isobutane in the cells. During degassing, the polyethylene polymerizes to form the closed cells of the foam which are then relatively rigid. The foam block thus obtained is smooth on the surface because of the presence of a skin which has formed on the walls of the extrusion mold. This block of foam is then cut so as to obtain at least one face with cut cells, this face being intended to form the exfoliating surface of the abrasive element.

Le bloc de mousse est ensuite découpé à la dimension souhaitée pour obtenir l'élément abrasif 40. De préférence, la mousse est découpée sous forme d'une plaque d'environ 7 mm d'épaisseur ayant deux grandes faces dont au moins une qui comporte les alvéoles coupés, la face comportant les alvéoles coupés étant en regard de la paroi du moule.The block of foam is then cut to the desired size to obtain the abrasive element 40. Preferably, the foam is cut in the form of a plate of about 7 mm thick having two large faces, at least one of which comprises the cells cut, the face having the cut cells facing the wall of the mold.

On dispose cette plaque de mousse dans un moule dont la cavité a la forme du corps du flacon que l'on souhaite réaliser, sur la paroi destinée à former l'une des faces sensiblement planes de la paroi latérale du corps.This foam plate is placed in a mold whose cavity has the shape of the body of the bottle that it is desired to make, on the wall intended to form one of the substantially plane faces of the side wall of the body.

La plaque est maintenue dans le moule par tout moyen d'accrochage qui résiste à la chaleur. Elle peut par exemple être fixée au moule au moyen de crochets, d'adhésif double face, de Velcro®, ou encore par un système d'aspiration. Elle peut également être maintenue dans un décrochement prévu dans la paroi interne du moule, les dimensions du décrochement étant légèrement inférieures à celles de la plaque de mousse de manière à la maintenir.The plate is held in the mold by any attachment means that is heat resistant. It can for example be fixed to the mold by means of hooks, double-sided adhesive, Velcro®, or by a suction system. It can also be maintained in a recess provided in the inner wall of the mold, the dimensions of the recess being slightly lower than those of the foam plate so as to maintain it.

De préférence, la mousse est comprimée dans le moule si bien que lorsque le flacon sort du moule, la mousse se détend et vient en surépaisseur sur le flacon. Lorsque la mousse est maintenue dans le moule grâce au décrochement, elle n'est pas nécessairement comprimée.Preferably, the foam is compressed in the mold so that when the bottle comes out of the mold, the foam relaxes and comes extra thick on the bottle. When the foam is held in the mold thanks to the recess, it is not necessarily compressed.

On injecte ensuite dans ce moule du polyéthylène pour réaliser une préforme comportant une partie tubulaire fermée à son extrémité inférieure et se raccordant supérieurement au col délimitant l'ouverture 21. Un gaz chaud est ensuite injecté à travers l'ouverture 21 à l'intérieur de la préforme, de manière à dilater la partie tubulaire suffisamment chaude, jusqu'à ce que celle-ci épouse sensiblement la forme de la surface intérieure du moule et de la face de la plaque de mousse tournée vers l'intérieur du moule.This mold is then injected with polyethylene to produce a preform comprising a tubular part closed at its lower end and being connected superiorly to the neck defining the opening 21. A hot gas is then injected through the opening 21 inside the opening. the preform, so as to expand the sufficiently hot tubular portion, until it substantially matches the shape of the inner surface of the mold and the face of the foam plate facing the mold interior.

Compte tenu de la température encore élevée de la préforme, la face de la plaque tournée vers l'intérieur du moule fond légèrement au contact du flacon et se soude en refroidissant sur la paroi extérieure du flacon. En outre, la surface extérieure du flacon peut venir épouser les alvéoles 42 de la mousse grâce au soufflage. L'élément abrasif 40 est ainsi parfaitement fixé sur le corps 20 du flacon.In view of the still high temperature of the preform, the face of the plate facing the interior of the mold melts slightly in contact with the bottle and is welded by cooling on the outer wall of the bottle. In addition, the outer surface of the bottle can come to marry the cells 42 of the foam through blowing. The abrasive element 40 is thus perfectly fixed on the body 20 of the bottle.

La température de la préforme et la pression qu'elle subit lorsque le gaz est injecté sont choisies de manière à ce qu'elles permettent à la mousse de se souder sur la paroi du flacon et qu'elles ne permettent pas à la mousse de fondre dans le moule ni à l'air emprisonné dans les cellules de la mousse d'exploser.The temperature of the preform and the pressure it undergoes when the gas is injected are chosen so that they allow the foam to weld on the wall of the bottle and that they do not allow the foam to melt in the mold nor to the air trapped in the cells of the foam to explode.

En particulier, lorsque la mousse et le flacon sont en polyéthylène, les paramètres de température et de pression sont très proches de ceux utilisés pour réaliser un flacon classique en polyéthylène. La préforme en polyéthylène a par exemple une température comprise entre 50 et 100°C et subit une pression comprise entre 8 et 10 bars.In particular, when the foam and the bottle are made of polyethylene, the temperature and pressure parameters are very close to those used to produce a conventional polyethylene bottle. The polyethylene preform has, for example, a temperature of between 50 and 100 ° C. and is subjected to a pressure of between 8 and 10 bars.

Au lieu d'être réalisé par injection-soufflage, le corps du flacon pourrait être réalisé par extrusion-soufflage.Instead of being made by injection blow molding, the body of the bottle could be made by extrusion blow molding.

Au lieu d'être soudée sur la paroi latérale du corps du flacon, la plaque de mousse peut être collée, notamment avec une colle chaude ou encore avec un adhésif double face. Le corps du flacon est alors réalisé de façon classique, sans disposer la plaque de mousse dans le moule au préalable.Instead of being welded to the side wall of the body of the bottle, the foam plate can be glued, in particular with a hot glue or with a double-sided adhesive. The body of the bottle is then produced in a conventional manner, without disposing the foam plate in the mold beforehand.

Alternativement encore, la mousse peut être soudée en reprise sur la paroi du flacon, par exemple par une soudure miroir.Alternatively again, the foam may be soldered back onto the wall of the bottle, for example by a mirror weld.

Pour utiliser le flacon, l'utilisateur saisit le flacon par sa paroi latérale 22 en disposant ses doigts dans les concavités 25 prévues sur les bords du corps alors que le flacon est fermé par la capsule 30. Il peut ensuite appliquer la mousse 40 sur sa peau, comme on l'a illustré à la figure 3, en frottant légèrement, après par exemple avoir appliqué le gel douche sur la zone à traiter. En utilisant le flacon comme poignée, l'utilisateur a ainsi une bonne prise pour effectuer son gommage. En outre, l'effet combiné de la surface abrasive et du produit permet d'accroître l'efficacité du gommage.To use the bottle, the user grasps the bottle by its side wall 22 by placing its fingers in the concavities 25 provided on the edges of the body while the bottle is closed by the capsule 30. It can then apply the foam 40 on its skin, as illustrated in the figure 3 , rubbing lightly after, for example, applying the shower gel to the area to be treated. By using the bottle as a handle, the user has a good grip to perform his exfoliation. In addition, the combined effect of the abrasive surface and the product increases the effectiveness of the scrub.

Après chaque gommage, l'utilisateur peut passer le flacon sous l'eau de manière à nettoyer la mousse. Celle-ci se nettoie facilement du fait qu'elle comporte des cellules fermées si bien que les peaux mortes qui pourraient se fixer sur la mousse, restent en surface.After each scrub, the user can pass the bottle under the water to clean the foam. This is easy to clean because it has closed cells, so that dead skin that could attach to the foam remains on the surface.

Selon un autre mode de réalisation illustré à la figure 4, le récipient 110 peut être sous forme d'un pot comportant un corps 120 cylindrique de révolution, comportant dans sa partie supérieure une pièce annulaire 124 filetée délimitant une ouverture 121. L'ouverture 121 est relativement importante afin par exemple de permettre le prélèvement du produit contenu dans le corps du récipient au moyen d'un applicateur introduit à travers l'ouverture.According to another embodiment illustrated in figure 4 , the container 110 may be in the form of a pot having a cylindrical body 120 of revolution, having in its upper part an annular piece 124 threaded delimiting an opening 121. The opening 121 is relatively large for example to allow the removal of the product contained in the body of the container by means of an applicator introduced through the opening.

Un couvercle 130 est alors prévu pour fermer l'ouverture 121 du corps par vissage sur la pièce annulaire filetée. Le couvercle comporte une face supérieure 131 plane recouverte d'un élément abrasif 140. L'élément abrasif 140 a cette fois la forme d'un disque. L'élément abrasif 140 peut être collé sur le couvercle ou encore être soudé en étant surinjecté sur le couvercle.A cover 130 is then provided to close the opening 121 of the body by screwing on the threaded annular piece. The cover has a flat upper face 131 covered with an abrasive element 140. The abrasive element 140 this time has the shape of a disc. The abrasive element 140 can be glued to the lid or welded by being surinjected on the lid.

Selon une variante de ce mode de réalisation illustrée à la figure 7, le corps 320 du récipient peut être destiné à contenir une dose de produit pour un usage unique, le corps pouvant être rempli par l'utilisateur à chaque utilisation.According to a variant of this embodiment illustrated in FIG. figure 7 , the body 320 of the container may be intended to contain a dose of product for a single use, the body can be filled by the user with each use.

Le corps 320 a par exemple la forme d'une poignée. Il comporte également dans sa partie supérieure une pièce annulaire 324 filetée délimitant une ouverture 321.The body 320 has for example the shape of a handle. It also comprises in its upper part an annular piece 324 threaded defining an opening 321.

Un couvercle 330 est alors prévu pour restreindre l'ouverture 321 du corps par vissage sur la pièce annulaire filetée. Le couvercle comporte une face supérieure 331 plane recouverte d'un élément abrasif 340. L'élément abrasif est cette fois traversé par des passages 322 débouchant, d'une part, sur la surface extérieure de l'élément abrasif et, d'autre part, à l'intérieur du corps.A cover 330 is then provided to restrict the opening 321 of the body by screwing on the threaded annular piece. The cover comprises a flat upper face 331 covered with an abrasive element 340. This time, the abrasive element is traversed by passages 322 opening on the one hand to the outer surface of the abrasive element and on the other hand , inside the body.

Selon cette variante, l'utilisateur peut appliquer le produit en même temps qu'il frotte la surface avec l'élément abrasif puisque le produit provenant du corps du récipient est acheminé sur la face extérieure de la mousse par les passages 322.According to this variant, the user can apply the product while rubbing the surface with the abrasive element since the product from the body of the container is conveyed on the outer face of the foam through the passages 322.

Selon un autre mode de réalisation illustré à la figure 5, le récipient 210 peut comporter un corps tubulaire 220 à parois souples, comportant un col fileté 224 à une première extrémité, le col étant en partie fermé par une paroi transversale 223 traversée par un orifice 221. Le corps tubulaire 220 est fermé à l'extrémité opposée au col par pincement de manière à former un tube.According to another embodiment illustrated in figure 5 , the container 210 may comprise a tubular body 220 with flexible walls, having a threaded collar 224 at one end, the neck being partially closed by a transverse wall 223 through which an orifice 221 passes. The tubular body 220 is closed at end opposite the neck by pinching so as to form a tube.

Un bouchon de fermeture 230 est prévu pour se visser sur le col, grâce à une jupe filetée. Le bouchon a une forme sensiblement tronconique et comporte une paroi transversale supérieure plane, recouverte d'un élément abrasif 240. De préférence, la paroi latérale du bouchon de forme tronconique s'évase vers sa paroi supérieure de manière à faciliter la préhension du capuchon lorsque l'utilisateur l'applique sur sa peau, comme on l'a illustré à la figure 6, s'il utilise le bouchon seul. L'utilisateur peut également tenir l'ensemble du récipient avec le tube fermé par le bouchon pour appliquer la mousse.A closure cap 230 is provided to screw on the neck, thanks to a threaded skirt. The plug has a substantially frustoconical shape and has a flat upper transverse wall, covered with an abrasive element 240. Preferably, the side wall of the frustoconical shaped cap flares towards its upper wall so as to facilitate the gripping of the cap when the user applies it to his skin, as illustrated in figure 6 if he uses the cap alone. The user can also hold the entire container with the tube closed by the stopper to apply the foam.

Ce mode de réalisation est particulièrement adapté à une application sur le visage du fait que la surface de la mousse est relativement petite.This embodiment is particularly suitable for application on the face because the foam surface is relatively small.

En variante, on peut prévoir que le corps du récipient est surmonté d'une pompe ou d'une valve.Alternatively, it can be provided that the body of the container is surmounted by a pump or a valve.

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'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
