Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention se rapporte au domaine de la cosmétique et notamment du maquillage, du traitement cosmétique du visage. Plus particulièrement la présente invention concerne l'application de produit cosmétique et/ou de soin, fluide ou pâteux, sur le visage mais également sur d'autres parties du corps, de forme complexe.The invention relates to the field of cosmetics and in particular makeup, cosmetic treatment of the face. More particularly, the present invention relates to the application of cosmetic and / or care product, fluid or pasty, on the face but also on other parts of the body, of complex shape.

L'invention trouve un intérêt particulier dès qu'il s'agit d'appliquer de façon simple et efficace un tel produit, sur des surfaces complexes telles que les lèvres. Par surfaces complexes il faut comprendre des surfaces non planes, par exemple présentant dans l'espace une succession de courbures concaves et convexes.The invention is of particular interest when it comes to simply and effectively applying such a product on complex surfaces such as lips. By complex surfaces it is necessary to understand non-planar surfaces, for example having in space a succession of concave and convex curvatures.

En outre, lorsqu'ils coopèrent avec un réservoir présentant un col doté d'un orifice circulaire de petit diamètre, de tels applicateurs doivent être suffisamment souples et élastiques pour passer à travers l'orifice circulaire, s'y déformer, puis reprendre leur forme initiale, tout en retenant le produit fluide ou pâteux qu'il s'agit d'appliquer sur la surface extérieure complexe.In addition, when they cooperate with a reservoir having a neck with a small diameter circular orifice, such applicators must be sufficiently flexible and resilient to pass through the circular orifice, deform and then return to their shape. initially, while retaining the fluid or pasty product that it is to apply on the complex outer surface.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

De nombreux applicateurs ont déjà été proposés; un grand nombre concerne l'application de produit pâteux sur des fibres kératiniques telles que des cils ou des sourcils. Mais la problématique n'est pas exactement la même lorsqu'il s'agit d'appliquer un tel produit de façon simple, uniforme et efficace sur des surfaces complexes.Many applicators have already been proposed; a large number relates to the application of pasty product on keratinous fibers such as eyelashes or eyebrows. But the problem is not exactly the same when it comes to applying such a product in a simple, uniform and effective way on complex surfaces.

A titre illustratif, le dispositif applicateur décrit dans le document EP 0 875 169 permet d'appliquer du mascara sur des cils ou des sourcils, de deux façons différentes ; en surface grâce à une première zone sensiblement cylindrique, et en profondeur grâce à une zone distale de l'applicateur, effilée à la façon d'un pinceau. Plusieurs formes volumiques sont montrées dans ce document, toutes adaptées à l'application de mascara sur des cils ou des sourcils.As an illustration, the applicator device described in the document EP 0 875 169 allows mascara to be applied to eyelashes or eyebrows in two different ways; at the surface through a first substantially cylindrical zone, and in depth through a distal zone of the applicator, tapered like a brush. Several volume shapes are shown in this document, all adapted to the application of mascara on eyelashes or eyebrows.

On connait aussi le document US 2005/0217691 pour appliquer du mascara sur des fibres kératiniques. Cet applicateur présente des formes variées assurant un excellent ratio surface sur volume de rétention de produit. Des arches et/ou des lamelles permettent un tel effet.We also know the document US 2005/0217691 to apply mascara to keratinous fibers. This applicator has various forms ensuring an excellent surface-to-volume ratio of product retention. Arches and / or slats allow such an effect.

La demande de brevet FR 2 969 470 concerne encore un applicateur de produit fluide ou pâteux sur des fibres kératiniques, comprenant une âme allongée réalisée monobloc avec un ensemble de tiges souples et flexibles encastrées à chacune de leurs extrémités sur l'âme. Cet arrangement est particulièrement adapté à l'application de mascara ; il permet de charger un maximum de produit pâteux et surtout de le maintenir efficacement malgré le passage à travers l'orifice d'essorage du contenant.The patent application FR 2 969 470 further relates to an applicator fluid or paste on keratin fibers, comprising an elongate core made integral with a set of flexible and flexible rods embedded at each of their ends on the core. This arrangement is particularly suitable for the application of mascara; it makes it possible to load a maximum of pasty product and especially to maintain it effectively despite passing through the wiper orifice of the container.

On connait par ailleurs des dispositifs applicateurs de « gloss » (ou produit pâteux) tels que décrits par exemple dans le document US 7 866 906 . Dans ce document, l'applicateur doit prendre du produit pâteux renfermé dans un récipient fermé par un orifice, passer à travers cet orifice chargé de produit, afin de l'appliquer sur les lèvres de l'utilisatrice. Pour ce faire, l'applicateur en lui-même comprend au moins deux branches souples qui définissent entre elles un orifice ou réservoir de produit. Cet orifice est unique et les branches sont floquées c'est-à-dire qu'elles présentent une surface extérieure rugueuse. Le volume extérieur général défini par l'applicateur est effilé vers sa partie distale. Ce type d'applicateur est finalement peu souple et sa caractéristique principale réside dans le flocage de sa surface extérieure. Ce flocage qui consiste dans la fixation de microfibres sur tout ou partie de la surface extérieure de l'applicateur, représente une étape de fabrication en elle-même, ce qui a un coût.Also known devices applicators "gloss" (or pasty product) as described for example in the document US 7,866,906 . In this document, the applicator must take pasty product contained in a closed container with an orifice, pass through this orifice loaded with product, in order to apply it on the lips of the user. To do this, the applicator itself comprises at least two flexible branches which define between them a hole or product reservoir. This orifice is unique and the branches are flocked, that is to say they have a rough outer surface. The general external volume defined by the applicator is tapered towards its distal part. This type of applicator is finally not very flexible and its main characteristic lies in the flocking of its outer surface. This flocking, which consists of fixing microfibers on all or part of the outer surface of the applicator, represents a manufacturing step in itself, which has a cost.

En outre, les microfibres générées par le flocage et présentes en surface des applicateurs de ce type, rendent ces applicateurs peu hygiéniques car elles favorisent la rétention et le développement local de bactéries. Cet aspect, très négatif, constitue un inconvénient non négligeable de tous les applicateurs munis de surfaces floquées.In addition, microfibers generated by flocking and present on the surface of applicators of this type, make these applicators unhygienic because they promote the retention and local development of bacteria. This aspect, very negative, is a significant disadvantage of all applicators with flocked surfaces.

On connait aussi un applicateur selon la demande WO 2013/153528 qui révèle un applicateur de produit cosmétique effilé et plat, comprenant donc deux surfaces principales d'application, au moins trois ouvertures définies par quatre branches longitudinales, transversales ou obliques. Différentes géométries correspondant à cette définition sont montrées ; on est donc ici en présence d'un applicateur plat dont l'une ou l'autre des surfaces principales plates, permettent d'appliquer le produit. Cet arrangement et cette géométrie essentiellement plate ne sont pas bien adaptés pour appliquer un produit pâteux sur des surfacesWe also know an applicator according to demand WO 2013/153528 which reveals a tapered and flat cosmetic product applicator, thus comprising two main application surfaces, at least three openings defined by four longitudinal, transverse or oblique branches. Different geometries corresponding to this definition are shown; we are here in the presence of a flat applicator which one or the other flat main surfaces, allow to apply the product. This arrangement and this essentially flat geometry are not well suited for applying a pasty product to surfaces

WO 2012/085398 divulgue un dispositif applicateur comprenant une arche encastrée en deux extrémités de l'âme. WO 2012/085398 discloses an applicator device comprising an arch embedded in two ends of the core.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention vise à remédier aux inconvénients de l'état de la technique et notamment à proposer un applicateur de produit fluide, liquide ou pâteux, dans le domaine de la cosmétique ou du soin, qui permette d'appliquer le produit sur des surfaces complexes tout en conservant une charge optimale de produit malgré le passage à travers un orifice de petit diamètre.The invention aims to remedy the drawbacks of the state of the art and in particular to propose a fluid, liquid or pasty product applicator, in the field of cosmetics or care, which makes it possible to apply the product to complex surfaces. while maintaining an optimal product load despite passing through a small diameter orifice.

Pour ce faire est proposé un dispositif applicateur selon la revendication 1.For this purpose, an applicator device according to claim 1 is proposed.

Par arche longitudinale on entend un élément effilé qui s'étend sensiblement selon l'axe XX longitudinal du dispositif.By longitudinal arch is meant a tapered element which extends substantially along the longitudinal axis XX of the device.

L'effet de pompage du produit n'est pas obtenu dans l'art antérieur du domaine considéré c'est-à-dire pour l'application de produit fluide ou pâteux sur des surfaces complexes. Ainsi, de façon nouvelle et inventive, la présente invention permet notamment un traitement ou un maquillage des lèvres ou de toute autre surface complexe de ce type. En particulier la forme générale extérieure galbée de l'applicateur permet de se conformer à diverses formes pour l'application.The pumping effect of the product is not obtained in the prior art of the field considered, that is to say for the application of fluid or pasty product on complex surfaces. Thus, in a new and inventive way, the present invention allows in particular a treatment or a make-up of the lips or any other complex surface of this type. In particular, the generally curved outer shape of the applicator makes it possible to conform to various forms for the application.

De façon préférée, le dispositif est monobloc.Preferably, the device is monobloc.

En outre, le dispositif selon l'invention peut comprendre une pointe effilée prévue à l'une de ses extrémités longitudinales. Cette pointe permet par exemple de tracer des contours avec davantage de précision.In addition, the device according to the invention may comprise a tapered tip provided at one of its longitudinal ends. This tip allows for example to draw contours with more precision.

De façon avantageuse, le dispositif comprend plusieurs arches radialement espacées autour de l'âme. Par plusieurs arches, on entend couramment de deux à trente-six arches.Advantageously, the device comprises several arches radially spaced around the core. By several arches one commonly hears from two to thirty-six arches.

Selon un mode particulier de réalisation de l'invention, ladite au moins une arche présente une forme ondulée selon l'axe XX.According to a particular embodiment of the invention, said at least one arch has a corrugated shape along the axis XX.

Avantageusement, ladite âme comprend un volume complémentaire au volume extérieurement défini par ladite au moins une arche, ledit volume représentant entre 5% et 95% du volume total du dispositif. Bien entendu l'ensemble présente la forme générale extérieure définie plus haut. Le volume complémentaire peut être plein ou partiellement plein de matière.Advantageously, said core comprises a volume complementary to the volume externally defined by said at least one arch, said volume representing between 5% and 95% of the total volume of the device. Of course, the assembly has the general external shape defined above. The complementary volume may be full or partially full of material.

Selon une caractéristique de l'invention, le dispositif applicateur comprend en outre des picots saillants vis-à-vis de la surface extérieure de ladite au moins une arche et/ou de l'âme. Cette caractéristique améliore la tenue du produit sur l'applicateur. Par picots saillants, on entend tout relief ou excroissance, de préférence allongé, qui s'étend en dehors de la surface extérieure des arches et/ou de l'âme.According to a feature of the invention, the applicator device further comprises protruding pins vis-à-vis the outer surface of said at least one arch and / or the core. This feature improves the strength of the product on the applicator. The term "protruding pins" means any relief or protuberance, preferably elongated, that extends outside the outer surface of the arches and / or the core.

Conformément à un mode de réalisation de l'invention, le dispositif comprend au moins une arche encastrée en un point et au moins une arche encastrée en deux points de l'âme. Bien entendu de nombreuses combinaisons peuvent être réalisées sur cette base ; l'homme de métier choisira en fonction du cas particulier d'application.According to one embodiment of the invention, the device comprises at least one recessed arch at a point and at least one recessed arch at two points of the core. Of course, many combinations can be made on this basis; the skilled person will choose according to the particular case of application.

Selon encore une caractéristique de l'invention, lesdites arches encastrées présentent une longueur comprise entre 70% et 95% de la longueur totale du dispositif.According to another characteristic of the invention, said recessed arches have a length of between 70% and 95% of the total length of the device.

En accord avec l'invention, lesdites arches encastrées en un point présentent une extrémité libre orientée vers l'intérieur du volume du dispositif. Cet aspect diminue les risques de voir de telles arches se courber voire se casser lors de certaines manipulations.In accordance with the invention, said arches recessed at a point have a free end oriented towards the inside of the volume of the device. This aspect reduces the risk of such arches bending or breaking during certain manipulations.

De façon préférée, lesdits picots s'étendent perpendiculairement à la surface sur laquelle ils sont encastrés.Preferably, said pins extend perpendicularly to the surface on which they are embedded.

A titre préféré, le dispositif peut être mono-composant, ou bi-composant, obtenu par moulage, avec ou sans addition de matière.As a preference, the device may be single-component, or two-component, obtained by molding, with or without addition of material.

Selon l'invention, le dispositif applicateur peut être obtenu par un procédé d'injection, de bi-injection, de co-injection, de moulage, de surmoulage, de compression, de coulage, de stéréo-lithographie, d'agencement de matière et/ou d'ajout d'au moins une couche de matière.According to the invention, the applicator device can be obtained by a method of injection, bi-injection, coinjection, molding, overmolding, compression, casting, stereo-lithography, material arrangement. and / or adding at least one layer of material.

En outre, il peut être réalisé en une matière thermoplastique, en élastomère vulcanisable ou toute matière techniquement équivalente.In addition, it can be made of a thermoplastic material, vulcanizable elastomer or any technically equivalent material.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

La figure 1A illustre donc une première forme géométrique d'un dispositif applicateur selon l'invention. Sa forme générale extérieure est allongée et axisymétrique autour d'un axe XX. Cette forme générale comprend un premier volume renflé 1 raccordé à un deuxième volume renflé 2 par une zone plus fine 3 en ce sens que sa section transversale est inférieure à la plus grande section transversale du premier 1 et du deuxième 2 volume renflé. Cette forme comprend quelques variantes, illustrées sur les figures 1A, 2A et 3A. Cette forme a été étudiée afin d'épouser parfaitement des surfaces dites complexes, c'est-à-dire non planes et définies par des courbes. Ce sont des formes volumiques permettant notamment à l'utilisateur qui fait tourner le dispositif autour de l'axe XX, de déposer uniformément le produit sur la surface courbe.The Figure 1A thus illustrates a first geometric form of an applicator device according to the invention. Its outer general shape is elongated and axisymmetric around an axis XX. This general shape comprises a first enlarged volume 1 connected to a second bulged volume 2 by a thinner zone 3 in the sense that its cross section is smaller than the largest cross section of the first 1 and the second 2 bulged volume. This form includes some variants, illustrated on the FIGS. 1A, 2A and 3A . This form has been studied to perfectly fit so-called complex surfaces, that is to say non-flat and defined by curves. These are volume shapes that allow the user to rotate the device around the axis XX, to deposit the product uniformly on the curved surface.

Selon le mode de réalisation des figures 1A, 1B, 1C et 1D, la forme extérieure générale du dispositif ressemble à celle d'une cacahouète ; cette forme est particulièrement adaptée pour déposer du produit sur des lèvres ; le premier 1 et le deuxième 2 volumes présentent sensiblement la même taille. Une partie effilée ou pointe 4 est préférentiellement prévue à l'extrémité distale du dispositif. Par extrémité distale on entend l'extrémité longitudinalement disposée à l'opposé de l'extrémité apte à recevoir la tige 5 d'un moyen de préhension du dispositif applicateur. L'homme de métier peut effiler selon un angle choisi la pointe 4 qui peut, sans sortir du cadre de l'invention, être arrondie.According to the embodiment of FIGS. 1A, 1B, 1C and 1D , the general external shape of the device resembles that of a peanut; this form is particularly suitable for depositing product on lips; the first 1 and the second 2 volumes have substantially the same size. A tapered portion or tip 4 is preferably provided at the distal end of the device. By distal end is meant the end longitudinally disposed opposite the end adapted to receive the rod 5 of a gripping means of the applicator device. The skilled person can taper at a chosen angle the tip 4 which can, without departing from the scope of the invention, be rounded.

Un deuxième mode de réalisation de l'invention, quant à la forme extérieure générale, est illustré sur les figures 2A, 2B, 2C et 2D. Selon cette option, deux demi-volumes différents sont présents : le premier correspond à un demi-volume du premier mode de réalisation, qui, de ce fait ne sera pas davantage explicité ; le deuxième demi volume comprend une partie bombée axialement disposée sensiblement au niveau de la partie la plus fine 3. Ce dessin sera préférentiellement choisi pour l'application de produit sur les lèvres. La figure 2B montre clairement cette différence dans les demi-volumes.A second embodiment of the invention, as to the general external shape, is illustrated on the Figures 2A, 2B, 2C and 2D . According to this option, two different half volumes are present: the first corresponds to half a volume of the first embodiment, which, therefore, will not be further explained; the second half volume comprises an axially curved portion disposed substantially at the level of the thinnest portion 3. This drawing will preferably be chosen for the application of product on the lips. The Figure 2B clearly shows this difference in the half volumes.

Les figures 3a, 3B, 3C et 3D montrent un troisième mode de réalisation, de forme générale galbée qui est clairement visible sur la figure 3D. Des formes complexes peuvent être obtenues si le dispositif est obtenu par moulage, avec ou sans addition de matière. Comme il sera explicité plus loin, le dispositif peut être mono-composant ou bi-composant, en fonction des contraintes techniques.The FIGS. 3a, 3b, 3c and 3d show a third embodiment, of generally curved shape which is clearly visible on the 3D figure . Complex shapes can be obtained if the device is obtained by molding, with or without addition of material. As will be explained later, the device can be single-component or two-component, depending on the technical constraints.

Les figures 4A, 4B, 4C montrent un exemple plus précis : on voit en effet sur ces figures que le dispositif applicateur comprend notamment au moins une arche longitudinale flexible 10, 11 encastrée en au moins un point 101 ; 111, 112 sur une âme 15. Par âme il faut comprendre le volume solide constitutif du dispositif à l'exclusion de la ou des arches 10, 11. L'âme s'étend longitudinalement, selon l'axe XX.The Figures 4A, 4B, 4C show a more specific example: it is seen in these figures that the applicator device comprises in particular at least one flexible longitudinal arch 10, 11 embedded in at least one point 101; 111, 112 on a soul 15. By soul it is necessary to understand the solid volume constituting the device excluding the arch or arches 10, 11. The core extends longitudinally along the axis XX.

Les arches 10 sont encastrées en un seul point 101 ; ce point est notamment situé à l'une des extrémités de l'arche 10 qui est ainsi disposée en porte à faux sur l'âme 15. Une plus grande flexibilité est ainsi conférée à ce type d'arche 10. En elles-mêmes les arches 10, 11 sont allongées et fines (ratio longueur sur épaisseur de l'ordre de 10/1) afin de présenter intrinsèquement une certaine flexibilité. La matière choisie participe à la flexibilité ; on choisit par exemple une matière thermoplastique, un élastomère vulcanisable ou toute matière techniquement équivalente.The arches 10 are embedded in a single point 101; this point is in particular located at one end of the arch 10 which is thus arranged cantilevered on the core 15. Greater flexibility is thus imparted to this type of arch 10. In themselves the arches 10, 11 are elongated and thin (length to thickness ratio of the order of 10/1) to inherently present a certain flexibility. The chosen subject participates in flexibility; for example, a thermoplastic material, a vulcanizable elastomer or any technically equivalent material is chosen.

Afin de conférer la forme générale extérieure caractéristique de l'invention, la ou les arches 10, 11 présentent une forme ondulée selon l'axe XX.In order to confer the general external shape characteristic of the invention, the arch or arches 10, 11 have a corrugated shape along the axis XX.

Sur les figures 4A, 4B et 4C le dispositif comprend une arche 10 encastrée en un seul point 101, et une pluralité d'arches 11 encastrées en deux points 111, 112.On the Figures 4A, 4B and 4C the device comprises an arch 10 embedded in a single point 101, and a plurality of arches 11 embedded in two points 111, 112.

Sur les figures 5A et 5B, le dispositif comprend quelques arches 10 en porte à faux, radialement entourées d'arches 11 encastrées à leurs deux extrémités 111, 112.On the Figures 5A and 5B , the device comprises a few arches 10 cantilevered radially surrounded by arches 11 embedded at their two ends 111, 112.

Les arches 10, 11 définissent avec l'âme 15 un réservoir de produit, de volume variable apte à obtenir un effet de pompage du produit présent dans ledit réservoir. Le réservoir est ici défini par le volume entre les arches 10, 11 et l'âme 15. Les arches étant flexibles, leurs déformations génèrent une variation du volume du réservoir, soit un effet de pompage du produit fluide ou pâteux.The arches 10, 11 define with the core 15 a product reservoir of variable volume capable of obtaining a pumping effect of the product present in said reservoir. The tank is here defined by the volume between the arches 10, 11 and the core 15. The arches being flexible, their deformations generate a variation in the volume of the tank, a pumping effect of the fluid or pasty product.

L'homme de métier choisira, en fonction de différents paramètres, le nombre et la répartition des arches 10, 11.The skilled person will choose, depending on different parameters, the number and distribution of the arches 10, 11.

Les figures 6A, 6B, 6C et 6D montrent un mode de réalisation selon lequel les arches sont toutes du type 11 c'est à dire encastrées en deux points 111 et 112. Les arches 11 sont identiques entre elles et réparties dans un demi-volume cylindrique ; elles sont angulairement régulièrement réparties comme le montre clairement les figures 6B et 6D. Le second demi-volume 6 peut être plein ou vide de matière, au choix de l'homme de métier.The FIGS. 6A, 6B, 6C and 6D show an embodiment according to which the arches are all of the type 11, ie recessed in two points 111 and 112. The arches 11 are identical to each other and distributed in a half-cylindrical volume; they are angularly distributed regularly as clearly Figures 6B and 6D . The second half volume 6 may be full or empty of material, at the choice of the skilled person.

La figure 7A illustre un exemple particulier où une seule arche 11 est prévue, encastrée à ses deux extrémités. Par ailleurs les figures 7B à 7E représentent, par des coupes transversales schématiques, différentes variantes correspondant à différents positionnements des arches ; la figure 7B est une coupe transversale du dispositif selon la figure 7A, selon la coupe AA. Selon la figure 7C, trois arches sensiblement identiques sont prévues, placées côte à côte dans un faible secteur angulaire (de l'ordre de 90 °). Conformément à la figure 7D, trois arches sont prévues ; elles ne sont pas de forme identiques, en particulier l'une est plus épaisse donc rigide que les autres. Encore une fois, l'homme de métier choisira la forme la plus appropriée à l'application envisagée.The Figure 7A illustrates a particular example where a single arch 11 is provided, recessed at both ends. Moreover, Figures 7B to 7E represent, by schematic cross sections, different variants corresponding to different positions of the arches; the Figure 7B is a cross-section of the device according to the Figure 7A , according to the AA section. According to Figure 7C , three substantially identical arches are provided, placed side by side in a small angular sector (of the order of 90 °). In accordance with the Figure 7D three arches are planned; they are not identical in shape, in particular one is thicker and therefore stiff than the others. Once again, the skilled person will choose the most appropriate form for the intended application.

Les figures 8A et 8B correspondent à un exemple de réalisation où toutes les arches 11 sont de type encastrées à chacune de leurs extrémités. Elles sont angulairement régulièrement réparties, et présentent des formes différentes. Bien que ce concept paraisse difficile à réaliser, les technologies actuellement disponibles permettent une fabrication aisée, de masse.The Figures 8A and 8B correspond to an embodiment where all the arches 11 are recessed type at each of their ends. They are angularly regularly distributed, and have different shapes. Although this concept seems difficult to achieve, currently available technologies allow for easy, mass manufacturing.

Les figures 9 et 10 illustrent un élément applicateur comportant un dispositif applicateur. On voit clairement que le dispositif coopère avec la tige 5, est porté par son extrémité opposée à un moyen de préhension de type capuchon de fermeture de récipient, bien connu en soi. Selon la figure 9, le dispositif présente une forme extérieure générale en cacahouète, et il comprend des arches 10 en porte à faux (au nombre de trois) angulairement entourées d'arches 11.The Figures 9 and 10 illustrate an applicator element comprising an applicator device. It is clearly seen that the device cooperates with the rod 5, is carried by its opposite end to a container cap closure type gripping means, well known per se. According to figure 9 , the device has a general external shape in peanut, and it comprises arches 10 cantilevered (three in number) angularly surrounded by arches 11.

Sur la figure 10 on voit que le dispositif comprend en outre des picots 12 saillants vis-à-vis de la surface extérieure ils émergent ; les picots 12 peuvent être présents sur la surface extérieure d'une ou de plusieurs arches 10, 11 et/ou sur la surface extérieure de l'âme 15, plus précisément ici du demi-volume 6.On the figure 10 it is seen that the device further comprises pins 12 protruding vis-à-vis the outer surface they emerge; the pins 12 can be present on the outer surface of one or more arches 10, 11 and / or on the outer surface of the core 15, more precisely here of the half-volume 6.

Les figures 11A et 11B ont trait à un mode de réalisation comportant des arches 11 et un demi-volume 6 ; des picots 12 sont régulièrement répartis sur la surface extérieure du demi-volume 6, permettant une meilleure retenue de produit ; ils offrent en outre une surface rugueuse, par exemple pour le gommage et/ou le nettoyage de la peau.The Figures 11A and 11B relate to an embodiment having arches 11 and a half-volume 6; studs 12 are evenly distributed on the outer surface of the half-volume 6, allowing better product retention; they also offer a rough surface, for example for scrubbing and / or cleaning the skin.

Les figures 12A et 12B montrent une variante de réalisation selon laquelle les picots sont répartis sur les arches 11. Un effet de rétention de produit est ici recherché au niveau des arches.The Figures 12A and 12B show an alternative embodiment according to which the pins are distributed over the arches 11. A product retention effect is here sought at the arches.

Les figures 13A et 13B illustrent une solution où à la fois les arches 11 et le demi-volume 6 sont munis de picots 12. Cette solution technique , bien que plus difficile à mettre en oeuvre que les autres par la précision qu'elle requiert, est cependant très intéressante en ce qu'elle cumule les avantages des autres solutions.The Figures 13A and 13B illustrate a solution where both arches 11 and half volume 6 are provided with pins 12. This technical solution, although more difficult to implement than others by the precision it requires, is however very interesting in it combines the advantages of other solutions.

D'autres combinaisons des caractéristiques décrites ci-avant peuvent être imaginées et mises en oeuvre par l'homme de métier sans sortir du cadre de l'invention selon la revendication 1.Other combinations of the characteristics described above can be imagined and implemented by those skilled in the art without departing from the scope of the invention according to claim 1.
