The support serves as a closure unit for a container (20).

Description

La présente invention concerne un ensemble pour le conditionnement et l'application d'un produit notamment cosmétique ou de soin en particulier sous forme de poudre ou de fluide.The present invention relates to an assembly for the packaging and the application of a product, in particular a cosmetic or a care product, in particular in the form of a powder or a fluid.

EP 1 086 904 divulgue un ensemble conforme au préambule de la revendication 1. EP 1 086 904 discloses an assembly according to the preamble of claim 1.

Il existe de nombreux types d'applicateurs de produits cosmétiques, et en particulier des applicateurs munis d'un organe en mousse attaché ou non à une capsule. De tels applicateurs sont enfermés dans une enceinte étanche pour les préserver de toute pollution ou évaporation. Ils peuvent être comprimés ou non dans l'enceinte. Lorsqu'on souhaite utiliser ce type d'applicateur pour des applications à tout le visage ou encore pour une application corporelle, on doit augmenter le diamètre de l'organe en mousse. Or, on utilise souvent des mousses de densité élevée à cellules fines qui ont une capacité de rétention par capillarité importante. On obtient alors un organe en mousse de densité élevée et de diamètre important qui est relativement dur. Par ailleurs, de telles mousses se conforment difficilement aux différents reliefs de la surface sur laquelle on applique le produit, à cause de leur grande rigidité. D'autre part, ces mousses qui sont souvent hydrophiles et qui contiennent des absorbeurs d'humidité ont tendance à gonfler au contact du produit et venir frotter sur les bords des parois de l'enceinte servant de logement. Il est ainsi difficile d'introduire l'organe d'application dans son logement du fait de la résistance trop élevée.There are many types of applicators of cosmetic products, and in particular applicators with a foam member attached or not to a capsule. Such applicators are enclosed in a sealed enclosure to protect them from any pollution or evaporation. They can be compressed or not in the enclosure. When it is desired to use this type of applicator for applications to the entire face or for a body application, it is necessary to increase the diameter of the foam member. However, high density fine cell foams which have a high capillarity retention capacity are often used. This produces a high density foam member of large diameter which is relatively hard. Furthermore, such foams are difficult to conform to the different reliefs of the surface on which the product is applied, because of their high rigidity. On the other hand, these foams which are often hydrophilic and which contain moisture absorbers tend to swell in contact with the product and come scrub on the edges of the walls of the enclosure serving as housing. It is thus difficult to introduce the applicator member into its housing because of the resistance that is too high.

Aussi, est-ce un des objets de l'invention que de réaliser un ensemble pour le conditionnement et l'application d'un produit cosmétique ou de soin qui ne présente pas les inconvénients de la technique antérieure.Also, is it an object of the invention to provide an assembly for the packaging and application of a cosmetic or care product that does not have the disadvantages of the prior art.

C'est en particulier un objet de l'invention que de réaliser un tel ensemble qui permet d'appliquer avec douceur un produit cosmétique ou de soin.In particular, it is an object of the invention to provide such a set which allows a cosmetic or care product to be gently applied.

C'est encore un autre objet de l'invention que de réaliser un ensemble pour le conditionnement et l'application d'un produit cosmétique ou de soin qui permet de s'adapter à différents reliefs de la surface sur laquelle on applique le produit.It is yet another object of the invention to provide an assembly for the packaging and application of a cosmetic or care product which makes it possible to adapt to different reliefs of the surface on which the product is applied.

C'est encore un autre objet de l'invention que de réaliser un ensemble pour le conditionnement et l'application d'un produit cosmétique ou de soin qui peut facilement être introduit dans un logement étanche.It is yet another object of the invention to provide an assembly for the packaging and application of a cosmetic or care product which can easily be introduced into a sealed housing.

Selon l'invention, ces objets sont atteints en réalisant un ensemble pour le conditionnement et l'application d'un produit tel que défini dans la revendication 1.According to the invention, these objects are achieved by providing an assembly for the packaging and application of a product as defined in claim 1.

Par surface d'application on entend toute surface externe de l'organe d'application pouvant être mise en contact avec une surface à traiter notamment pour amener le produit sur ladite surface à traiter et/ou pour l'étaler.By application surface is meant any external surface of the applicator member that can be brought into contact with a surface to be treated, in particular to bring the product to said surface to be treated and / or to spread it.

Ainsi, grâce à la configuration de l'organe d'application comportant au moins une portion plus compressible que le reste de l'organe, la force d'appui que celui-ci exerce, lorsque l'utilisatrice l'applique sur sa peau par exemple, est au moins en partie absorbée. On obtient ainsi un ensemble présentant une flexibilité qui permet une application relativement douce sur la surface à traiter.Thus, thanks to the configuration of the applicator member comprising at least a portion more compressible than the rest of the organ, the support force that it exerts, when the user applies it on his skin by example, is at least partly absorbed. This gives a set with flexibility that allows a relatively smooth application to the surface to be treated.

La seconde portion est configurée de manière à favoriser une compression uniforme ou préférentielle de l'organe d'application. En effet, en disposant la portion plus compressible d'un côté de l'organe d'application, on peut faire pivoter la première partie de l'organe d'application ainsi que la surface d'application par rapport à un axe de l'organe d'application, de manière à ce que ladite surface d'application s'adapte au relief de la surface à traiter avec un angle différent de l'angle avec lequel l'utilisatrice tient l'organe d'application et l'applique.The second portion is configured to promote uniform or preferential compression of the applicator member. Indeed, by arranging the more compressible portion of one side of the application member, can rotate the first part of the applicator member as well as the application surface with respect to an axis of the applicator member, so that said application surface is adapted to the relief of the surface to be treated with an angle different from the angle with which the user holds the applicator member and applies it.

En outre, la présence de la seconde portion plus compressible permet également de faciliter l'introduction de l'organe d'application dans son logement en limitant les frottements que peut avoir l'organe d'application sur les parois internes du logement lorsque notamment le diamètre de l'organe d'application est égal ou supérieur à celui du logement.In addition, the presence of the second more compressible portion also facilitates the introduction of the applicator member into its housing by limiting the friction that can have the applicator member on the inner walls of the housing when in particular the diameter of the applicator member is equal to or greater than that of the housing.

De préférence, la première portion de l'organe d'application qui est adjacente à sa surface d'application est en matériau compressible. L'organe d'application présente ainsi une seconde flexibilité lui conférant une certaine souplesse dans l'application. On utilise par exemple une mousse à cellules ouvertes ou semi-ouvertes notamment choisie parmi les mousses de polyuréthane, de polyéthylène, de chlorure de polyvinyle, de polyester, de polyether, de polyéthylène acétate de vinyle, de polyacétate de vinyle, de caoutchouc naturel ou synthétique. On peut également utiliser un fritté en matériau souple, notamment choisi parmi les élastomères, les élastomères thermoplastiques, les chlorures de polyvinyle ou les polyéthylènes acétate de vinyle.Preferably, the first portion of the applicator member which is adjacent to its application surface is of compressible material. The application member thus has a second flexibility giving it a certain flexibility in the application. For example, an open-cell or semi-open-cell foam is used, chosen especially from foams of polyurethane, polyethylene, polyvinyl chloride, polyester, polyether, polyethylene vinyl acetate, polyvinyl acetate or natural rubber. synthetic. It is also possible to use a sinter of flexible material, especially chosen from elastomers, thermoplastic elastomers, polyvinyl chlorides or polyethylenes vinyl acetate.

Selon un premier mode de réalisation, la seconde portion de l'organe d'application est en partie formée d'un matériau identique au matériau formant la première portion. Selon ce mode de réalisation, la surface de la section transversale de ladite partie de la seconde portion est, sur au moins une partie de sa hauteur axiale, inférieure à la surface de la section transversale de la première portion.According to a first embodiment, the second portion of the applicator member is partly formed of a material identical to the material forming the first portion. According to this embodiment, the cross sectional area of said portion of the second portion is, over at least part of its axial height, smaller than the cross sectional area of the first portion.

A cet effet, différentes configurations de la seconde portion sont envisagées.For this purpose, different configurations of the second portion are envisaged.

Selon une première configuration, la seconde portion comprend une ou plusieurs gorge(s) débouchant sur une surface latérale de l'organe d'application. La (les) gorge(s) est (sont) orientée(s) selon un plan transversal à un axe X longitudinal de l'organe d'application et est (sont) formée(s) sur au moins une partie de la périphérie de l'organe d'application. Ces gorges peuvent être formées dans un plan perpendiculaire à l'axe X de l'organe d'application ou encore dans un plan incliné par rapport à l'axe X.In a first configuration, the second portion comprises one or more grooves (s) opening on a side surface of the applicator member. The groove (s) is (are) oriented in a plane transverse to a longitudinal axis X of the applicator member and is (are) formed on at least a part of the periphery of the the implementing body. These grooves may be formed in a plane perpendicular to the axis X of the applicator member or in a plane inclined with respect to the axis X.

Selon cette première configuration, les gorges ont une hauteur axiale sensiblement identique en l'absence de contraintes s'exerçant sur l'organe d'application. Alternativement, au moins une des gorges peut avoir une hauteur axiale différente de celles des autres gorges. Par ailleurs, chaque gorge peut avoir une hauteur axiale constante ou alternativement, au moins une des gorges est de hauteur axiale non constante.According to this first configuration, the grooves have a substantially identical axial height in the absence of constraints exerted on the applicator member. Alternatively, at least one of the grooves may have an axial height different from those of the other grooves. Moreover, each groove may have a constant axial height or alternatively, at least one of the grooves is of non-constant axial height.

En l'absence de contrainte, les gorges peuvent être espacées deux à deux de manière identique. Alternativement, les gorges sont espacées de manière différente. On pourra en effet utiliser des gorges qui sont de plus en plus espacées entre elles lorsqu'on s'éloigne de la surface d'application de l'organe d'application. Cela permet notamment d'augmenter la souplesse de façon progressive. On peut également utiliser des gorges de profondeur différente.In the absence of stress, the grooves may be spaced two by two in an identical manner. Alternatively, the grooves are spaced differently. It will be possible to use grooves which are increasingly spaced apart when moving away from the application surface of the applicator member. This allows in particular to increase the flexibility gradually. It is also possible to use grooves of different depths.

L'espace entre deux gorges successives est par exemple supérieur à la hauteur axiale desdites gorges.The space between two successive grooves is for example greater than the axial height of said grooves.

La ou les gorge(s) peut(vent) avoir une section transversale au plan dans lequel elle(s) s'étend(ent) de différentes formes. En effet, la section peut être en forme de C, de U à fond carré ou arrondi, ou encore en forme de V. La section en forme de V permet notamment d'obtenir une souplesse plus progressive que celle obtenue avec une section en forme de U.The groove (s) may (wind) have a cross section to the plane in which it (s) extends (ent) of different shapes. Indeed, the section may be C-shaped, U-shaped with a square or rounded bottom, or V-shaped. The V-shaped section makes it possible to obtain a more gradual flexibility than that obtained with a shaped section. from U.

Selon une seconde configuration, la seconde portion comprend une ou plusieurs rainure(s) sensiblement axiale(s).According to a second configuration, the second portion comprises one or more grooves (s) substantially axial (s).

De préférence, il comprend une pluralité de rainures espacées radialement de manière régulière sur toute la périphérie de l'organe d'application.Preferably, it comprises a plurality of grooves spaced radially evenly over the entire periphery of the applicator member.

Selon une variante, la seconde portion peut à la fois présenter des gorges et des rainures.According to a variant, the second portion can both have grooves and grooves.

Selon un deuxième mode de réalisation, la seconde portion est constituée d'un matériau différent du matériau formant la première portion. De préférence, la seconde portion est constituée d'un matériau présentant une compressibilité supérieure à la compressibilité du matériau formant la première portion. Il s'agit par exemple d'une mousse à cellules ouvertes ou semi-ouvertes différente de celle formant la première portion mais qui peut être également choisie parmi les mousses de polyuréthane, de polyéthylène, de chlorure de polyvinyle, de polyester, de polyether, de polyéthylène acétate de vinyle, de polyacétate de vinyle, de caoutchouc naturel ou synthétique.According to a second embodiment, the second portion is made of a material different from the material forming the first portion. Preferably, the second portion consists of a material having a compressibility greater than the compressibility of the material forming the first portion. This is for example a foam with open or semi-open cells different from that forming the first portion but which may also be chosen from foams of polyurethane, polyethylene, polyvinyl chloride, polyester, polyether, polyethylene vinyl acetate, polyvinyl acetate, natural or synthetic rubber.

Selon une variante, l'organe d'application est constitué d'au moins deux blocs concentriques, de matériaux différents de part leur nature et/ou leur densité, par exemple de deux blocs de mousse de même nature et de densité . différente. Les blocs concentriques peuvent avoir la même hauteur axiale ou une hauteur axiale différente.According to a variant, the applicator member consists of at least two concentric blocks, of different materials because of their nature and / or their density, for example two blocks of foam of the same nature and density. different. The concentric blocks may have the same axial height or a different axial height.

Selon un troisième mode de réalisation, la seconde portion comprend un ressort, notamment en métal ou en plastique.According to a third embodiment, the second portion comprises a spring, in particular metal or plastic.

Avantageusement, l'organe d'application est réalisé d'une seule pièce usinée ou moulée. Dans ce cas, lorsque l'organe d'application est constitué d'au moins deux matériaux différents, il pourra être obtenu par bi-injection.Advantageously, the applicator member is made of a single machined or molded part. In this case, when the applicator member consists of at least two different materials, it can be obtained by bi-injection.

Avantageusement encore, la seconde portion comprend un évidement central. En choisissant les dimensions de l'évidement, on peut ajuster la dureté et la compression de l'organe d'application.Advantageously, the second portion comprises a central recess. By choosing the dimensions of the recess, it is possible to adjust the hardness and the compression of the applicator member.

L'organe d'application présente une surface d'application destinée à être appliquée sur la surface à traiter qui peut être plane, creuse par exemple concave, ou bombée par exemple convexe. Pour des applications nécessitant une distribution homogène de produit permettant d'appliquer un film régulier, comme par exemple pour un autobronzant, on utilise de préférence une surface plane ou convexe. Pour les autres applications dans lesquelles on applique une plus grande quantité de produit, on pourra utiliser une surface concave. En outre, la surface d'application peut avantageusement être inclinée de manière à favoriser un angle d'application déterminé.The applicator member has an application surface intended to be applied to the surface to be treated, which may be flat, hollow, for example concave, or curved, for example, convex. For applications requiring a homogeneous product distribution to apply a regular film, such as for example a self-tanner, preferably a flat or convex surface is used. For other applications in which a larger amount of product is applied, a concave surface may be used. In addition, the application surface may advantageously be inclined so as to favor a determined application angle.

Avantageusement, l'organe d'application est recouvert, au moins en partie, d'un flocage, d'un tissé, d'un non tissé, d'un film poreux ou non poreux. On peut ainsi obtenir le toucher que l'on souhaite en fonction par exemple du produit que l'on applique. En outre, l'organe d'application comprend des éléments, notamment en forme de picots, de bossages, d'inscriptions, formant saillie par rapport à la surface d'application et s'étendant sur tout ou partie de ladite surface d'application. On peut ainsi modifier les sensations procurées par la surface d'application. Les éléments formant saillie permettent également à au moins une partie de la surface d'application d'avoir une fonction stimulante, de massage, de drainage ou encore une fonction favorisant la micro circulation.Advantageously, the applicator member is covered, at least in part, with a flocking, a woven fabric, a nonwoven fabric, a porous or non-porous film. It is thus possible to obtain the touch that one wishes according to, for example, the product that is applied. In addition, the applicator member comprises elements, in particular in the form of pins, bosses, inscriptions, protruding from the application surface and extending over all or part of said application surface. . It is thus possible to modify the sensations provided by the application surface. The projecting elements also allow at least a portion of the application surface to have a stimulating function, massage, drainage or a function promoting microcirculation.

L'organe d'application présente une section transversale circulaire, ovale, ou polygonale, par exemple triangulaire, carrée, hexagonale, etc...The applicator member has a circular, oval, or polygonal cross-section, for example triangular, square, hexagonal, etc.

De préférence, l'organe d'application est fixé à l'élément de fermeture notamment par encliquetage, vissage, collage ou soudage. De préférence, l'organe d'application est monté dans l'élément de fermeture de manière telle que la seconde portion ne soit pas visible de l'extérieur tout en assurant sa fonction. Par exemple, l'élément de fermeture comprend une jupe recouvrant au moins en partie la seconde portion.Preferably, the applicator member is fastened to the closure element in particular by snapping, screwing, gluing or welding. Preferably, the applicator member is mounted in the closure member so that the second portion is not visible from the outside while performing its function. For example, the closure element comprises a skirt covering at least partly the second portion.

Le premier et le second logements sont avantageusement séparés par l'intermédiaire d'un élément perméable au produit, notamment sous forme d'une grille, d'un tamis, d'une valve à ouverture unidirectionnelle en direction du second logement, d'une couche de mousse, d'un tissé, ou d'un non-tissé. Ainsi, le produit présent dans le premier logement peut traverser l'élément perméable pour atteindre l'organe d'application présent dans le second logement dans lequel il s'imprègne.The first and second housings are advantageously separated by means of a product-permeable element, in particular in the form of a grid, a sieve, a valve with a unidirectional opening towards the second housing, a layer of foam, a woven, or a nonwoven. Thus, the product present in the first housing can pass through the permeable element to reach the applicator member present in the second housing in which it impregnates.

Selon un autre aspect, l'invention concerne l'utilisation d'un ensemble tel qu'il vient d'être décrit pour le conditionnement et l'application d'un produit cosmétique sous forme d'une poudre ou d'un fluide, notamment d'une crème, d'un lait, d'un gel ou d'une lotion, par exemple un blush, un fard à joues, un fard à paupières, un rouge à lèvre, un fond de teint, un produit de soin, un produit solaire, un produit capillaire, etc...According to another aspect, the invention relates to the use of an assembly as just described for the packaging and application of a cosmetic product in the form of a powder or a fluid, in particular a cream, a milk, a gel or a lotion, for example a blush, a blush, an eyeshadow, a lipstick, a foundation, a care product, a solar product, a hair product, etc ...

Si on se réfère à la figure 1 on peut voir l'ensemble de conditionnement et d'application 10 conforme à un premier mode de réalisation de l'invention et représenté schématiquement. Cet ensemble comporte un corps cylindrique qui délimite un premier logement 20 délimité par une jupe cylindrique 21 dont une première extrémité 22 est fermée par un fond 24 et une seconde extrémité 23, est fermée par une paroi transversale 60. La paroi transversale 60 est un élément perforé qui a la forme d'une grille. La paroi transversale 60 sépare le premier logement 20 d'un second logement 30, situé au-dessus du premier logement 20. Le premier logement 20 est destiné à contenir un produit P qui est par exemple un produit cosmétique ou de soin. Le produit P peut être sous forme liquide, comme par exemple une crème liquide, ou un fond de teint liquide, ou encore sous forme de poudre, comme par exemple un fond de teint, un fard à paupières ou à joues. L'applicateur 40 est imprégné par capillarité par le produit.With reference to FIG. 1, it is possible to see the packaging and application assembly 10 according to a first embodiment of the invention and schematically represented. This assembly comprises a cylindrical body which delimits a first housing 20 delimited by a cylindrical skirt 21, a first end 22 is closed by a bottom 24 and a second end 23, is closed by a transverse wall 60. The transverse wall 60 is an element perforated which has the shape of a grid. The transverse wall 60 separates the first housing 20 from a second housing 30, located above the first housing 20. The first housing 20 is intended to contain a product P which is for example a cosmetic or care product. The product P may be in liquid form, for example a liquid cream, or a liquid foundation, or in the form of a powder, such as, for example, a foundation, an eyeshadow or cheeks. The applicator 40 is impregnated by capillarity with the product.

Le fond du logement supérieur 30 est formé par la paroi transversale 60 et présente une forme hémisphérique. Une extrémité du logement 30, opposée au fond 60, forme un bord libre 32 délimitant une ouverture 31. La surface extérieure du logement 30 comporte un filetage 33 destiné à coopérer avec un filetage correspondant 51 prévu sur la surface interne d'une jupe 52 d'un bouchon 50.The bottom of the upper housing 30 is formed by the transverse wall 60 and has a hemispherical shape. One end of the housing 30, opposite the bottom 60, forms a free edge 32 delimiting an opening 31. The outer surface of the housing 30 has a thread 33 intended to cooperate with a corresponding thread 51 provided on the inner surface of a skirt 52. a plug 50.

Un applicateur 40 d'axe X, solidaire du bouchon 50, est réalisé sous forme d'un bloc d'une mousse à cellules ouvertes de polyuréthane, de forme généralement sphérique conformé de manière correspondante au profil hémisphérique défini par le fond 60 du logement 30. Selon ce mode de réalisation, l'applicateur 40 a une surface d'application 44 convexe qui est recouverte d'un revêtement de flocage 45. L'applicateur 40 est fixé au bouchon 50 par collage.An applicator 40 of X axis, integral with the plug 50, is in the form of a block of a polyurethane open cell foam, of generally spherical shape shaped correspondingly to the hemispherical profile defined by the bottom 60 of the housing 30 According to this embodiment, the applicator 40 has a convex application surface 44 which is covered with a flocking coating 45. The applicator 40 is fixed to the cap 50 by gluing.

L'applicateur 40 est dimensionné par rapport au logement 30 de sorte que, en position fermée du bouchon 50, une portion au moins de la surface d'application de l'applicateur 40 soit au contact de la grille 60.The applicator 40 is dimensioned relative to the housing 30 so that, in the closed position of the stopper 50, at least a portion of the application surface of the applicator 40 is in contact with the grid 60.

L'applicateur 40 est muni d'une gorge 410 débouchant sur une surface latérale sur toute la périphérie de l'applicateur et orientée selon un plan perpendiculaire à l'axe X. Il s'agit par exemple d'une gorge annulaire de section transversale par rapport au plan dans lequel elle s'étend en forme de U à fond carré. A titre d'exemple, l'applicateur 40 présente une hauteur axiale H selon l'axe X de 35 mm environ et sa section transversale la plus large présente un diamètre D d'environ 35 mm. La gorge 410 présente une hauteur axiale h environ égale à 5 mm et de profondeur p environ égale à 10 mm. Il est bien évident que l'on peut utiliser une gorge 410 non continue formée sur une partie uniquement de la périphérie de l'applicateur.The applicator 40 is provided with a groove 410 opening on a lateral surface over the entire periphery of the applicator and oriented along a perpendicular plane This is, for example, an annular groove of cross section relative to the plane in which it extends in a U-shape with a square bottom. For example, the applicator 40 has an axial height H along the X axis of about 35 mm and its widest cross section has a diameter D of about 35 mm. The groove 410 has an axial height h approximately equal to 5 mm and a depth p approximately equal to 10 mm. It is obvious that one can use a non-continuous groove 410 formed on only a part of the periphery of the applicator.

Toutes ces dimensions ainsi que celles qui seront données dans la suite de la description ne sont données qu'à titre purement indicatif. Il est évident que ces dimensions peuvent varier en fonction de la taille de l'applicateur et de l'effet souhaité. En outre, ces dimensions correspondent à des dimensions mesurées en l'absence de toute contrainte exercée sur l'applicateur.All these dimensions as well as those which will be given in the following description are given for information only. It is obvious that these dimensions may vary depending on the size of the applicator and the desired effect. In addition, these dimensions correspond to dimensions measured in the absence of any stress exerted on the applicator.

Lors de l'application, l'utilisatrice enlève le bouchon 50 et applique la surface d'application 44 de l'applicateur 40, sur la surface à traiter S, son visage par exemple, comme cela est représenté à la figure 2. La présence de la gorge annulaire 410 permet de réduire la force d'appui exercée par l'applicateur sur le visage. Par ailleurs, l'applicateur 40 s'adapte plus facilement à la surface du visage car la surface d'application pivote par rapport à l'organe de préhension ce qui permet d'obtenir un angle d'application de la surface qui est différent de l'angle avec lequel l'utilisatrice tient l'organe de préhension.During the application, the user removes the stopper 50 and applies the applicator surface 44 of the applicator 40 to the surface to be treated S, for example its face, as shown in FIG. the annular groove 410 reduces the pressing force exerted by the applicator on the face. Moreover, the applicator 40 adapts more easily to the surface of the face because the application surface pivots with respect to the gripping member, which makes it possible to obtain an angle of application of the surface that is different from the angle with which the user holds the gripping member.

Si on se réfère aux figures 3A à 30, on peut voir différents exemples de configurations de l'applicateur 40 selon le premier mode de réalisation. L'applicateur est représenté seul, mais il est bien évident qu'il peut être monté dans un ensemble 10 du type de celui représenté à la figure 1.With reference to FIGS. 3A-30, various examples of configurations of the applicator 40 according to the first embodiment can be seen. The applicator is shown alone, but it is obvious that it can be mounted in a set 10 of the type shown in FIG.

L'applicateur représenté aux figures 3A et 3B est un bloc de mousse de polyester formée d'une seule pièce. L'applicateur a une forme générale sensiblement cylindrique présentant une hauteur axiale H environ égale à 20 mm et une section transversale circulaire de diamètre D environ égal à 50 mm. L'applicateur présente une surface d'application 44 légèrement concave formée dans un plan sensiblement perpendiculaire à l'axe X. Il est en outre muni de trois gorges annulaires 410 qui sont également formées dans un plan sensiblement perpendiculaire à l'axe X. Les gorges 410 ont toutes une même hauteur axiale h, cette hauteur axiale étant en outre constante tout au long de la périphérie. On choisit par exemple des gorges de hauteur axiale h environ égale à 2 mm. L'intervalle i entre deux gorges est identique entre deux gorges consécutives. Il est environ égal à 2 mm. Enfin, la profondeur p de chaque gorge est légèrement plus faible que la portion centrale 46 de l'applicateur 40 située dans le même plan transversal. Les gorges ont par exemple une profondeur p environ égale à 15 mm. Comme le montre la figure 3B, les gorges 410 permettent de faire pivoter la surface d'application 44 par rapport à l'axe X.The applicator shown in FIGS. 3A and 3B is a block of polyester foam formed in one piece. The applicator has a generally cylindrical general shape having an axial height H approximately equal to 20 mm and a circular cross section of diameter D approximately equal to 50 mm. The applicator has a slightly concave application surface 44 formed in a plane substantially perpendicular to the X axis. It is further provided with three annular grooves 410 which are also formed in a plane substantially perpendicular to the X axis. grooves 410 all have the same axial height h, this axial height being furthermore constant throughout the periphery. For example, grooves of axial height h are chosen which are approximately equal to 2 mm. The interval i between two grooves is identical between two consecutive grooves. It is approximately equal to 2 mm. Finally, the depth p of each groove is slightly smaller than the central portion 46 of the applicator 40 located in the same transverse plane. The grooves have for example a depth p approximately equal to 15 mm. As shown in FIG. 3B, the grooves 410 make it possible to pivot the application surface 44 with respect to the axis X.

A la figure 3C, l'applicateur est légèrement différent de celui décrit en conformité avec les figures 3A et 3B. Tout d'abord, il présente une surface d'application 44 convexe. En outre, il comporte quatre gorges 410 qui sont de moins en moins espacées au fur et à mesure qu'on s'éloigne de la surface d'application 44. La première et la seconde gorges, en partant de la surface d'application, sont séparées d'un intervalle i environ égale à 5 mm, la seconde et la troisième gorges sont séparées d'un intervalle i environ égale à 3 mm, et enfin la troisième et la quatrième gorges sont séparées d'un intervalle i environ égale à 2 mm. Enfin, la profondeur de chaque gorge est relativement peu importante, à savoir qu'elle est plus faible que la portion centrale de l'applicateur 40 située dans le même plan transversal. Les gorges ont par exemple une profondeur p environ égale à 5 mm.In Figure 3C, the applicator is slightly different from that described in accordance with Figures 3A and 3B. First, it has a convex application surface 44. In addition, it comprises four grooves 410 which are less and less spaced as one moves away from the application surface 44. The first and second grooves, starting from the application surface, are separated by an interval i approximately equal to 5 mm, the second and third grooves are separated by an interval i approximately equal to 3 mm, and finally the third and fourth grooves are separated by an interval i approximately equal to 2 mm. Finally, the depth of each groove is relatively small, namely that it is smaller than the central portion of the applicator 40 located in the same transverse plane. The grooves have for example a depth p approximately equal to 5 mm.

L'applicateur 40 représenté aux figures 3D et 3E diffère de celui représenté en conformité avec les figures 3A et 3B en ce que sa surface d'application 44 est plane. Par ailleurs, l'applicateur a une forme générale sensiblement cylindrique présentant une hauteur axiale H environ égale à 35 mm et une section transversale circulaire de diamètre D environ égal à 35 mm. En outre, les gorges 410 sont au nombre de quatre, de hauteur axiale h environ égale à 2 mm. Les gorges sont relativement profondes, leur profondeur p étant environ égale à 15 mm. En effet, la profondeur p de la gorge est plus grande que la portion centrale 46 de l'applicateur correspondante située dans le même plan. On obtient ainsi une plus grande flexibilité biaxiale. En outre, la présence de ces gorges permet de faciliter l'introduction de l'applicateur 40 dans son logement 30, car comme on le voit à la figure 3E, les extrémités 47 des portions de l'applicateur formées entre chaque gorge se courbent facilement.The applicator 40 shown in Figures 3D and 3E differs from that shown in accordance with Figures 3A and 3B in that its application surface 44 is planar. Furthermore, the applicator has a generally cylindrical general shape having an axial height H approximately equal to 35 mm and a circular cross section of diameter D approximately equal to 35 mm. In addition, the grooves 410 are four in number, of axial height h approximately equal to 2 mm. The grooves are relatively deep, their depth p being approximately equal to 15 mm. Indeed, the depth p of the groove is greater than the central portion 46 of the corresponding applicator located in the same plane. This results in greater biaxial flexibility. In addition, the presence of these grooves facilitates the introduction of the applicator 40 in its housing 30, because as seen in Figure 3E, the ends 47 of the portions of the applicator formed between each groove bend easily .

A la figure 3F, on peut voir un applicateur 40 constitué d'un bloc de mousse de polyéthylène formée d'une seule pièce. L'applicateur a une forme générale sensiblement cylindrique de hauteur axiale H environ égale à 40 mm et de section transversale circulaire qui présente un diamètre D environ égal à 35 mm. L'applicateur présente une surface d'application 44 légèrement convexe formée dans un plan sensiblement perpendiculaire à l'axe X. Il est en outre muni de trois gorges annulaires 410 qui sont également formées dans un plan sensiblement perpendiculaire à l'axe X. Les gorges 410 sont espacées deux à deux d'une distance i identique, environ égale à 4 mm. Les gorges 410 ont par exemple une section transversale au plan dans lequel elles s'étendent en forme de V. La hauteur axiale h la plus grande de chaque gorge est environ égale à 4 mm. L'applicateur 40 est en outre muni d'un évidement central 43 de forme cylindrique. L'évidement central a une hauteur axiale H' environ égale à 17 mm et une section transversale de diamètre D' environ égal à 17 mm. L'évidement 43 est disposé dans la seconde portion de l'applicateur opposée à la surface d'application 44. L'évidement permet d'ajuster la dureté et la compression de l'organe d'application. Selon cet arrangement, il est préférable d'utiliser des gorges 410 peu profondes, de profondeur p environ égale à 4 mm.In Figure 3F, there can be seen an applicator 40 consisting of a block of polyethylene foam formed in one piece. The applicator has a generally cylindrical general shape of axial height H approximately equal to 40 mm and of circular cross section which has a diameter D approximately equal to 35 mm. The applicator has a slightly convex application surface 44 formed in a plane substantially perpendicular to the X axis. It is further provided with three annular grooves 410 which are also formed in a plane substantially perpendicular to the X axis. grooves 410 are spaced two by two from an identical distance, approximately equal to 4 mm. The grooves 410 have for example a cross section to the plane in which they extend in the shape of V. The axial height h the largest of each groove is approximately equal to 4 mm. The applicator 40 is further provided with a central recess 43 of cylindrical shape. The central recess has an axial height H 'approximately equal to 17 mm and a cross section with a diameter D' equal to approximately 17 mm. The recess 43 is disposed in the second portion of the applicator opposite to the application surface 44. The recess adjusts the hardness and compression of the applicator member. According to this arrangement, it is preferable to use shallow grooves 410, of depth p approximately equal to 4 mm.

L'applicateur 40 représenté à la figure 3N diffère de celui représenté à la figure 3F en ce que sa hauteur axiale H est moins importante que sa largeur D. En outre, il ne comporte qu'une gorge 410 de section transversale en forme de U. Par ailleurs, il est muni d'un évidement 43 qui s'étend sur pratiquement toute sa hauteur axiale H et sur une grande partie de sa largeur D. La hauteur axiale H' de l'évidement est en effet légèrement inférieure à la hauteur axiale H de l'applicateur de sorte que l'applicateur a une faible épaisseur en dessous de la partie centrale de la surface d'application 44. Une telle configuration permet encore d'améliorer la douceur d'application.The applicator 40 shown in FIG. 3N differs from that shown in FIG. 3F in that its axial height H is less important than its width D. In addition, it has only a groove 410 of U-shaped cross-section. Moreover, it is provided with a recess 43 which extends over practically its entire axial height H and over a large part of its width D. The axial height H 'of the recess is indeed slightly less than the height axial H of the applicator so that the applicator has a small thickness below the central portion of the application surface 44. Such a configuration further improves the smoothness of application.

A la figure 30 on a représenté un applicateur qui diffère de celui représenté à la figure 3N en ce qu'il ne comprend pas de gorge, et en ce que l'évidement a cette fois une forme tronconique. La portion de compressiblilité supérieure 41 est cette fois uniquement due à la présence de l'évidement 43. L'évidement 43 a une section transversale de diamètre sensiblement égale au diamètre D de la section transversale de l'applicateur à la base de l'applicateur pour se rétrécir en allant vers la surface d'application 44 jusqu'à un diamètre D'. La hauteur axiale H' de l'évidement est légèrement inférieure à la hauteur axiale H de l'applicateur de sorte que l'applicateur 40 a une faible épaisseur en dessous de la partie centrale de la surface d'application 44.In Figure 30 there is shown an applicator which differs from that shown in Figure 3N in that it does not include a groove, and in that the recess this time has a frustoconical shape. The upper compressiblility portion 41 is this time solely due to the presence of the recess 43. The recess 43 has a cross section of diameter substantially equal to the diameter D of the cross section of the applicator at the base of the applicator to tap towards the application surface 44 to a diameter D '. The axial height H 'of the recess is slightly smaller than the axial height H of the applicator so that the applicator 40 has a small thickness below the central part of the application surface 44.

L'applicateur 40 représenté à la figure 3G est constitué d'un bloc de mousse de chlorure de polyvinyle formée d'une seule pièce. L'applicateur a une forme générale sensiblement cylindrique de section transversale circulaire qui présente un diamètre D environ égal à 40 mm et une hauteur axiale H environ égale à 50 mm. L'applicateur présente une surface d'application 44 creuse formée dans un plan sensiblement perpendiculaire à l'axe X lui permettant d'appliquer une quantité relativement importante de produit. Il est en outre muni de deux gorges annulaires 410 qui sont également formées dans un plan sensiblement perpendiculaire à l'axe X. Les gorges 410 ont une section transversale au plan dans lequel elles s'étendent en forme de U à fond arrondi. Leur hauteur axiale h la plus grande est environ égale à 5 mm et elles sont séparées entre elles par une distance i environ égale à 5 mm. Leur profondeur p est relativement faible, par exemple environ égale à 5 mm.The applicator 40 shown in Figure 3G consists of a block of polyvinyl chloride foam formed in one piece. The applicator has a generally cylindrical general shape of circular cross section which has a diameter D approximately equal to 40 mm and an axial height H approximately equal to 50 mm. The applicator has a hollow application surface 44 formed in a plane substantially perpendicular to the X-axis allowing it to apply a relatively large amount of product. It is further provided with two annular grooves 410 which are also formed in a plane substantially perpendicular to the axis X. The grooves 410 have a cross section at the plane in which they extend in a U-shaped rounded bottom. Their greatest axial height h is approximately equal to 5 mm and they are separated from each other by a distance i approximately equal to 5 mm. Their depth p is relatively small, for example approximately equal to 5 mm.

Les arrangements de l'organe d'application représentés aux figures 3H à 3L ont une surface d'application 44 formée cette fois dans un plan incliné par rapport à l'axe X.The arrangements of the applicator member shown in FIGS. 3H to 3L have an application surface 44 formed this time in a plane inclined with respect to the axis X.

A la figure 3H, l'applicateur est constitué d'un bloc de mousse de polyéthylène acétate de vinyle formée d'une seule pièce. L'applicateur a une forme générale sensiblement cylindrique de section transversale circulaire qui présente un diamètre D environ égal à 45 mm et une hauteur axiale H la plus grande environ égale à 50 mm. L'applicateur présente une surface d'application 44 sensiblement plane formée dans un plan incliné par rapport à l'axe X. Il est en outre muni d'une gorge 410 unique de hauteur axiale h environ égale à 5 mm. La gorge 410 est formée dans un plan perpendiculaire à l'axe X. La gorge 410 a une section transversale au plan dans lequel elle s'étend en forme de U à fond carré. La profondeur p de la gorge 410 est environ égale à 15 mm.In Figure 3H, the applicator consists of a block of polyethylene vinyl acetate foam formed in one piece. The applicator has a generally cylindrical general shape of circular cross section which has a diameter D approximately equal to 45 mm and an axial height H the largest approximately equal to 50 mm. The applicator has a substantially planar application surface 44 formed in a plane inclined with respect to the axis X. It is further provided with a single groove 410 of axial height h approximately equal to 5 mm. The groove 410 is formed in a plane perpendicular to the axis X. The groove 410 has a cross section at the plane in which it extends in the form of U with a square bottom. The depth p of the groove 410 is approximately equal to 15 mm.

A la figure 3I, l'applicateur diffère de celui décrit en conformité avec la figure 3H en ce qu'il est muni de trois gorges 410 de plus faible hauteur axiale h, environ 3 mm, qui sont disposées dans un plan incliné par rapport à l'axe X. Elles sont disposées dans des plans parallèles entre eux et parallèles à la surface d'application 44. Les gorges 410 sont espacéés deux à deux d'une distance i constante, par exemple égale à la hauteur axiale des gorges. Les gorges ont une profondeur dont la composante p selon l'axe perpendiculaire à X est environ égale à 8 mm.In FIG. 3I, the applicator differs from that described in accordance with FIG. 3H in that it is provided with three grooves 410 of lower axial height h, approximately 3 mm, which are arranged in a plane inclined with respect to FIG. the axis X. They are arranged in planes parallel to each other and parallel to the application surface 44. The grooves 410 are spaced in pairs at a constant distance i, for example equal to the axial height of the grooves. The grooves have a depth whose component p along the axis perpendicular to X is approximately equal to 8 mm.

A la figure 3J, l'applicateur est identique à celui décrit à la figure 31 si ce n'est que les gorges 410 s'étendent dans un plan incliné par rapport à l'axe X qui n'est pas parallèle au plan de la surface d'application 44.In FIG. 3J, the applicator is identical to that described in FIG. 31 except that the grooves 410 extend in a plane inclined with respect to the axis X which is not parallel to the plane of the application area 44.

L'applicateur représenté à la figure 3K diffère cette fois de celui illustré à la figure 3I en ce que les trois gorges 410 ont une hauteur axiale h qui n'est pas constante tout le long de la périphérie. Cette hauteur axiale h varie entre 3 mm et 6 mm.The applicator shown in FIG. 3K differs this time from that illustrated in FIG. 3I in that the three grooves 410 have an axial height h which is not constant all along the periphery. This axial height h varies between 3 mm and 6 mm.

L'applicateur représenté à la figure 3L diffère de celui représenté à la figure 3H en ce qu'il présente une surface d'application 44 convexe. En outre, la gorge unique s'étend dans un plan incliné par rapport à l'axe X, sensiblement parallèle au plan dans lequel est formée la surface d'application. La gorge a une profondeur dont la composante p selon un axe perpendiculaire à X est environ égale à 8 mm. L'applicateur 40 est en outre muni d'un évidement central 43 de forme sensiblement hémisphérique.The applicator shown in FIG. 3L differs from that shown in FIG. 3H in that it has a convex application surface 44. In addition, the single groove extends in a plane inclined with respect to the axis X, substantially parallel to the plane in which the application surface is formed. The throat has a depth whose component p along an axis perpendicular to X is approximately equal to 8 mm. The applicator 40 is further provided with a central recess 43 of substantially hemispherical shape.

Selon toutes les configurations représentées aux figures 3A à 3N, la ou les gorges 410 sont formées sur toute la périphérie de l'applicateur, mais on peut envisager de façon alternative, de les former sur une partie uniquement.According to all the configurations shown in Figures 3A to 3N, the groove or grooves 410 are formed on the entire periphery of the applicator, but it is possible to envisage alternatively, to form them on a part only.

Selon une autre configuration représentée à la figure 3M, l'applicateur 40 est formé de deux blocs de mousse concentriques 420 et 430 de même nature, par exemple une mousse de polyether et de densité différente, le bloc central 420 étant de densité plus importante que le bloc extérieur 430. L'applicateur a une forme générale sensiblement cylindrique de section transversale circulaire qui présente un diamètre D environ égal à 45 mm et une hauteur axiale H environ égale à 45 mm. Le bloc central 420 est de forme générale cylindrique et présente un diamètre D1 environ égal à 31 mm. Le bloc extérieur 430, de forme générale annulaire, présente un rayon R environ égal à 7 mm. L'applicateur présente une surface d'application 44 plane formée dans un plan sensiblement perpendiculaire à l'axe X. Il est en outre muni d'une gorge annulaire 410 qui est également formée dans un plan sensiblement perpendiculaire à l'axe X. La gorge 410 est une gorge annulaire de section transversale par rapport au plan dans lequel elle s'étend en forme de U à fond carré. La gorge 410 a une hauteur axiale h environ égale à 5 mm et une profondeur p environ égale à 5 mm. En outre, on peut prévoir d'ajouter des rainures axiales du type de celles qui seront décrites ultérieurement en conformité avec la figure 4 dans le bloc central. Selon la configuration illustrée à la figure 3M, la surface d'application 44 présente une portion centrale 440 différente du reste de la surface d'application, notamment plus dure dans le présent exemple du fait que le bloc de mousse central 420 soit de densité plus importante que le bloc extérieur 430. Dans le cas où on utilise deux blocs concentriques 420 et 430 de nature différente, on pourra choisir un bloc central 420 ayant une fonction abrasive et un bloc extérieur 430 plus doux, ou inversement.According to another configuration shown in Figure 3M, the applicator 40 is formed of two concentric foam blocks 420 and 430 of the same kind, for example a polyether foam and different density, the central block 420 being of higher density than the outer block 430. The applicator has a generally cylindrical general shape of circular cross section which has a diameter D approximately equal to 45 mm and an axial height H approximately equal to 45 mm. The central block 420 is generally cylindrical in shape and has a diameter D 1 approximately equal to 31 mm. The outer block 430, of generally annular shape, has a radius R approximately equal to 7 mm. The applicator has a planar application surface 44 formed in a plane substantially perpendicular to the X axis. It is further provided with an annular groove 410 which is also formed in a plane substantially perpendicular to the X axis. groove 410 is an annular groove of cross section relative to the plane in which it extends in the form of U with a square bottom. The groove 410 has an axial height h approximately equal to 5 mm and a depth p approximately equal to 5 mm. In addition, provision may be made to add axial grooves of the type to be described later in accordance with Figure 4 in the central block. According to the configuration illustrated in Figure 3M, the application surface 44 has a central portion 440 different from the rest of the application surface, particularly harder in the present example of the fact that the central foam block 420 is more density In the case where two concentric blocks 420 and 430 of different types are used, it is possible to choose a central block 420 having an abrasive function and an outer block 430 which is softer, or vice versa.

Selon une variante non représentée de ce mode de réalisation, le bloc central 420 est muni d'un évidement. Selon une autre variante non représentée, le bloc central ne s'étend pas sur toute la hauteur axiale H de l'applicateur. Selon une autre variante, le bloc extérieur recouvre partiellement le bloc central, c'est-à-dire qu'il ne s'étend pas sur toute la hauteur axiale H de l'applicateur. Selon cette dernière variante, le bloc central a avantageusement une section transversale de diamètre plus important sur le reste de la hauteur axiale de manière à ce que la surface extérieure de l'applicateur soit sensiblement continue. Des gorges ou des rainures axiales du type de celles qui seront décrites ultérieurement en conformité avec la figure 4, sont alors formées dans la portion du bloc central de section transversale plus large. Alternativement, le bloc extérieur recouvre le bloc central sur sensiblement toute son extrémité adjacente à la surface d'application de sorte que la surface d'application est sensiblement entièrement formée par le bloc extérieur.According to a not shown variant of this embodiment, the central block 420 is provided with a recess. According to another variant not shown, the central block does not extend over the entire axial height H of the applicator. According to another variant, the outer block partially covers the central block, that is to say that it does not extend over the entire axial height H of the applicator. According to this latter variant, the central block advantageously has a larger diameter cross section over the rest of the axial height so that the outer surface of the applicator is substantially continuous. Axial grooves or grooves of the type to be described later in accordance with Figure 4, are then formed in the portion of the central block of wider cross section. Alternatively, the outer block covers the central block over substantially its entire end adjacent to the application surface so that the application surface is substantially entirely formed by the outer block.

Selon un deuxième mode de réalisation de l'invention représenté à la figure 4, l'applicateur est muni de rainures 411 formées selon l'axe X de l'applicateur. Comme pour les gorges décrites précédemment, les rainures axiales 411 peuvent prendre différentes configurations qui ne sont pas représentées. Il peut y avoir une rainure unique ou plusieurs rainures de hauteur axiale h plus ou moins importante, qui peut être constante ou variable le long de la périphérie de l'applicateur. La ou les rainure(s) peut(vent) avoir une largeur I constante tout au long de leur hauteur axiale ou encore varier selon l'axe X. Lorsque l'applicateur est muni de plusieurs rainures, celles-ci peuvent toutes avoir la même largeur I ou des largeurs différentes. Elles peuvent être espacées radialement deux à deux selon un intervalle i identique ou différent. Les rainures 411 peuvent également être plus ou moins inclinées par rapport à l'axe X. Dans l'exemple décrit à la figure 4, l'applicateur a une forme générale sensiblement cylindrique de section transversale circulaire qui présente un diamètre D environ égal à 33 mm et une hauteur axiale H environ égale à 45 mm. L'applicateur présente une surface d'application 44 sensiblement plane formée dans un plan perpendiculaire à l'axe X. L'applicateur est muni de plusieurs rainures 411 espacées radialement de façon régulière d'une distance environ égale à 8 mm. Chaque rainure 411 présente une largeur I environ égale à 3 mm et une hauteur axiale h environ égale à 8 mm.According to a second embodiment of the invention shown in Figure 4, the applicator is provided with grooves 411 formed along the X axis of the applicator. As for the grooves described above, the axial grooves 411 can take different configurations that are not shown. There may be a single groove or several grooves of axial height h more or less important, which may be constant or variable along the periphery of the applicator. The groove (s) may (wind) have a constant width I throughout their axial height or may vary along the X axis. When the applicator is provided with several grooves, these may all have the same width. width I or different widths. They may be radially spaced two by two in an identical or different interval. The grooves 411 may also be more or less inclined with respect to the X axis. In the example described in FIG. 4, the applicator has a generally cylindrical general shape with a circular cross-section that has a diameter D of about 33 mm. mm and an axial height H approximately equal to 45 mm. The applicator has a substantially planar application surface 44 formed in a plane perpendicular to the X axis. The applicator is provided with a plurality of grooves 411 spaced radially evenly a distance apart. about 8 mm. Each groove 411 has a width I approximately equal to 3 mm and an axial height h approximately equal to 8 mm.

Selon ce mode de réalisation, l'applicateur est en outre recouvert d'éléments 70 formant saillie par rapport à la surface d'application. Il s'agit par exemple d'une impression en relief.According to this embodiment, the applicator is further covered with elements 70 projecting from the application surface. This is for example a relief printing.

Selon un troisième mode de réalisation représenté à la figure 5, l'applicateur 40 est formé d'un empilement axial de blocs de mousse de nature différente. Selon ce mode de réalisation, l'applicateur est par exemple formé de trois blocs de mousse 49, 413 et 48, chacun de forme générale cylindrique, empilés axialement et collés entre eux. Les trois blocs présentent par exemple une hauteur axiale H identique, par exemple égale environ à 12 mm, et ont une section transversale de même diamètre D, par exemple égal à environ 45 mm. Le bloc de mousse central 413 est plus compressible que les autres blocs de mousse de manière à favoriser la compression de l'applicateur 40. Le bloc de mousse 49 définissant la surface d'application est en polyéther, le bloc de mousse central 413 est en caoutchouc naturel (en Natural Butadiene Rubber), et le troisième bloc de mousse 48 est en polyuréthane. Le reste de l'ensemble d'application est identique à celui décrit en conformité avec la figure 1.According to a third embodiment shown in FIG. 5, the applicator 40 is formed of an axial stack of foam blocks of different nature. According to this embodiment, the applicator is for example formed of three foam blocks 49, 413 and 48, each of generally cylindrical shape, stacked axially and glued together. The three blocks have for example an identical axial height H, for example equal to about 12 mm, and have a cross section of the same diameter D, for example equal to about 45 mm. The central foam block 413 is more compressible than the other foam blocks so as to promote the compression of the applicator 40. The foam block 49 defining the application surface is made of polyether, the central foam block 413 is in position. natural rubber (Natural Butadiene Rubber), and the third block of foam 48 is polyurethane. The remainder of the application set is identical to that described in accordance with FIG.

Selon un quatrième mode de réalisation représenté à la figure 6, l'applicateur 40 est constitué d'un fritté en élastomère thermoplastique. Il est monté sur le bouchon 50 par un ressort 42. Le ressort permet d'absorber en partie la force d'appui exercée par l'applicateur sur le visage. Selon la douceur de l'application que l'on souhaite obtenir, on choisit un ressort de raideur plus ou moins faible. Le bouchon 50 comprend une jupe 51 qui recouvre le ressort 42.According to a fourth embodiment shown in FIG. 6, the applicator 40 consists of a thermoplastic elastomer sinter. It is mounted on the cap 50 by a spring 42. The spring makes it possible to partially absorb the pressing force exerted by the applicator on the face. Depending on the softness of the application that one wishes to obtain, one chooses a spring of stiffness more or less weak. The plug 50 comprises a skirt 51 which covers the spring 42.

Il est évident que dans tous les modes de réalisation décrits précédemment, on peut prévoir de monter l'applicateur sur un ressort 42.It is obvious that in all the embodiments described above, it is possible to mount the applicator on a spring 42.

Avantageusement, on peut prévoir que l'applicateur selon l'un quelconque des modes de réalisation décrits précédemment, est muni d'une gaine en matériau compressible qui enveloppe tout ou partie de la seconde portion 41, notamment tout ou partie des gorges et/ou des rainures. La gaine est par exemple une peau qui peut être étanche au produit ou non. La gaine peut en outre être recouverte d'éléments formant saillie. Elle peut également être rétractable.Advantageously, it can be provided that the applicator according to any one of the embodiments described above, is provided with a sheath of material compressible which envelops all or part of the second portion 41, including all or part of the grooves and / or grooves. The sheath is for example a skin which can be tight to the product or not. The sheath may further be covered with protruding elements. It can also be retractable.

Dans tous les modes de réalisation qui viennent d'être décrits, l'applicateur 40 peut en outre contenir un adjuvant absorbeur d'eau ou d'huile, selon le produit qui est absorbé dans l'applicateur, de manière à maintenir le produit dans l'applicateur. On choisira par exemple une silice ou un alginate. Ainsi, l'applicateur peut être saturé de produit sans que celui-ci ait tendance à s'écouler hors de l'applicateur. L'applicateur 40 peut également contenir des agents antifongiques et/ou des agents bactéricides. L'applicateur peut aussi contenir des particules magnétisables.In all the embodiments which have just been described, the applicator 40 may furthermore contain a water or oil-absorbing adjuvant, depending on the product which is absorbed in the applicator, so as to keep the product in the applicator. For example, a silica or an alginate will be chosen. Thus, the applicator can be saturated with product without it tends to flow out of the applicator. Applicator 40 may also contain antifungal agents and / or bactericidal agents. The applicator may also contain magnetizable particles.

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 preferred embodiments of the invention. It is obvious that variations may be made without departing from the spirit of the invention as claimed hereinafter.
