Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne un dispositif applicateur d'un produit fluide ou pâteux sur des fibres kératiniques ou sur un épiderme. Notamment, l'invention concerne un dispositif applicateur d'un produit cosmétique, de maquillage ou de soins sur les poils, les cils, les sourcils, la peau ou les lèvres.The invention relates to a device for applying a fluid or pasty product to keratin fibers or to an epidermis. In particular, the invention relates to a device for applying a cosmetic, make-up or care product to the hair, eyelashes, eyebrows, skin or lips.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Il existe actuellement des dispositifs applicateurs d'un produit de type fluide ou pâteux sur des fibres kératiniques, comme des brosses à mascara par exemple, comprenant une âme centrale de forme allongée s'étendant selon un axe longitudinal, au moins une rangée de picots allongés comprenant une première extrémité encastrée dans l'âme et une deuxième extrémité libre. Habituellement les picots et l'âme sont formés d'une seule pièce de moulage, venant de matière l'une de l'autre. Par exemple le document FR 2 937 514 décrit de tels dispositifs applicateurs. Un inconvénient de ce type de réalisation est que les picots sont agencés de telle manière que le produit à appliquer est retenu au niveau de l'extrémité encastrée, près de l'âme, et ce une fois l'essoreur passé. Ainsi, le produit à appliquer se retrouve essentiellement près de l'âme de la brosse du dispositif applicateur, loin de l'extrémité libre des picots. En effet, lors du passage de l'essoreur, ces derniers se retrouvent complètement essorés, déchargés du produit à appliquer. Cela conduit l'utilisateur, dans le cas de fibres kératiniques par exemple, à appliquer un certain effort pour assurer que les fibres kératiniques pénètrent entre les picots de sorte à venir au plus près de l'âme du dispositif applicateur afin d'être enduites correctement de produit. Il y a au surplus des risques que le picot aille piquer, par exemple, la paupière lors d'un maquillage des cils, ou bien la peau lors d'un traitement des sourcils, ou bien les lèvres ou le cuir chevelu....There currently exist devices for applying a product of the fluid or pasty type to keratin fibres, such as mascara brushes for example, comprising a central core of elongated shape extending along a longitudinal axis, at least one row of elongated spikes comprising a first end embedded in the core and a second free end. Usually the barbs and the core are formed from a single molding piece, coming from one another. For example the document FR 2 937 514 describes such applicator devices. A disadvantage of this type of embodiment is that the pins are arranged in such a way that the product to be applied is retained at the recessed end, close to the core, once the wiper has passed. Thus, the product to be applied is found essentially close to the core of the brush of the applicator device, far from the free end of the spikes. Indeed, during the passage of the wringer, the latter find themselves completely wrung out, discharged from the product to be applied. This leads the user, in the case of keratin fibers for example, to apply a certain force to ensure that the keratin fibers penetrate between the barbs so as to come as close as possible to the core of the applicator device in order to be coated correctly of product. There are also risks that the pimple will sting, for example, the eyelid when making up the eyelashes, or the skin when treating the eyebrows, or the lips or the scalp....

Une solution à ce problème a été de fournir un dispositif applicateur dont l'âme de la brosse présente un diamètre augmenté. Pour permettre le passage de la brosse dans l'essoreur, le diamètre de ce dernier a été augmenté en conséquence. L'inconvénient de cette solution est qu'elle entraine une forte augmentation de la charge en produit à appliquer qui, une fois l'essoreur passé, reste essentiellement au niveau de l'âme. Lors de l'utilisation, un tel dispositif applicateur laisse des paquets de produit disgracieux sur les fibres kératiniques ainsi traitées.One solution to this problem has been to provide an applicator device whose brush core has an increased diameter. To allow the passage of the brush in the wringer, the diameter of the latter has been increased accordingly. The disadvantage of this solution is that it leads to a large increase in the load of product to be applied which, once the wiper has passed, remains essentially at the level of the core. During use, such an applicator device leaves unsightly packets of product on the keratin fibers thus treated.

Le document WO2015/110853 A1 décrit un dispositif applicateur suivant le préambule de la revendication 1.The document WO2015/110853 A1 describes an applicator device according to the preamble of claim 1.

EXPOSE DE L'INVENTIONDISCLOSURE OF THE INVENTION

Un but de l'invention est de fournir un dispositif applicateur d'un produit fluide ou pâteux permettant une application optimale du produit tout en procurant une sensation de confort amélioré à son utilisateur.An object of the invention is to provide an applicator device for a fluid or pasty product allowing optimal application of the product while providing a feeling of improved comfort to its user.

A cette fin, il est prévu, selon l'invention, un dispositif applicateur d'un produit fluide ou pâteux sur des fibres kératiniques ou sur la peau (épiderme), comprenant une âme allongée s'étendant selon un axe longitudinal X et de forme cylindrique longitudinale, une pluralité de picots répartis sur ladite âme, chaque picot s'étendant depuis une extrémité d'ancrage dans l'âme vers une extrémité libre et étant venu de matière avec ladite âme, chaque picot comportant, au niveau de l'extrémité libre, des moyens de captation et de retenue d'une quantité de produit fluide ou pâteux, caractérisé en ce que depuis l'extrémité d'ancrage, chaque picot comporte un premier tronçon de corps courbé dans un premier sens, puis un deuxième tronçon de corps courbé dans un sens opposé, puis se termine par l'extrémité libre, de sorte à donner une forme en « S » inversée à chaque picot.To this end, provision is made, according to the invention, for a device for applying a fluid or pasty product to keratin fibers or to the skin (epidermis), comprising an elongated core extending along a longitudinal axis X and of the shape longitudinal cylindrical, a plurality of pins distributed over said core, each pin extending from an anchoring end in the core towards a free end and being integral with said core, each pin comprising, at the level of the end free, means for capturing and retaining a quantity of fluid or pasty product, characterized in that from the anchoring end, each barb comprises a first section of body curved in a first direction, then a second section of body bent in an opposite direction, then terminated at the free end, so as to give an inverted "S" shape to each barb.

Ainsi, une telle structure du picot permet d'avoir une retenue distale d'une quantité de produit à appliquer sur les fibres kératiniques sans que ces dernières aient à se glisser complètement entre les picots. Cela apporte un confort optimal à son utilisateur tout en assurant une application optimale de produit sur les fibres kératiniques.Thus, such a structure of the barb makes it possible to have a distal retention of a quantity of product to be applied to the keratinous fibers without the latter having to slip completely between the barbs. This provides optimal comfort to its user while ensuring optimal product application on the keratin fibers.

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

En référence à la figure 1, nous allons décrire un mode de réalisation d'un dispositif applicateur 1. Le dispositif applicateur 1 selon l'invention est, ici, une brosse à mascara. Il comprend, ici, une âme 2 qui s'étend longitudinalement selon un axe longitudinal X. L'âme 2 peut présenter une section transversale constante ou non sur une longueur. Dans des réalisations les plus courantes, soit la section transversale est constante, soit la section transversale diminue depuis une extrémité proximale en prise avec un tube et/ou un manche de préhension jusqu'à une extrémité libre distale. De manière générale, l'âme 2 est de forme globalement cylindrique, de préférence de révolution d'axe l'axe longitudinal X. Ainsi, la section transversale de l'âme 2 peut présenter une forme circulaire, polygonale, ovale ou autre. Elle peut être axisymétrique. L'âme 2 peut être pleine ou creuse. La personne de l'art choisira en fonction des contraintes économiques et/ou techniques l'âme la plus appropriée.With reference to the figure 1 , we are going to describe an embodiment of an applicator device 1. The applicator device 1 according to the invention is, here, a mascara brush. It comprises, here, a core 2 which extends longitudinally along a longitudinal axis X. The core 2 may have a cross-section that is constant or not over a length. In the most common embodiments, either the cross section is constant, or the cross section decreases from a proximal end in engagement with a tube and/or a handle to a distal free end. In general, the core 2 is generally cylindrical in shape, preferably of axis revolution the longitudinal axis X. Thus, the cross section of the core 2 may have a circular shape, polygonal, oval or other. It can be axisymmetric. Core 2 can be solid or hollow. The person skilled in the art will choose the most appropriate core, depending on the economic and/or technical constraints.

D'autre part, le dispositif applicateur 1 selon l'invention comporte une pluralité de picots 10 répartis sur l'âme 2. Les picots 10 s'étendent en saillie depuis une surface périphérique externe de l'âme 2. Les picots 10 sont venus de matière avec l'âme 2. Notamment, les picots 10 sont obtenus de moulage avec l'âme 2. Ici, illustré, les picots 10 sont répartis en rangées adjacentes deux à deux s'étendant longitudinalement de manière parallèle à l'axe longitudinale X. Les picots 10 d'une même rangée s'étendent de la même manière selon une même orientation, parallèles les uns par rapport aux autres, depuis l'âme 2. Ici, en considérant deux rangées adjacentes, les picots 10 d'une des rangées adjacentes sont orientés de manière différente des picots 10 de l'autre des rangées adjacentes, par exemple, comme illustrée à la figure 1, à 180°. En variante, l'orientation est de 90°.On the other hand, the applicator device 1 according to the invention comprises a plurality of spikes 10 distributed over the core 2. The spikes 10 project from an outer peripheral surface of the core 2. The spikes 10 come of material with the core 2. In particular, the studs 10 are obtained by molding with the core 2. Here, illustrated, the studs 10 are distributed in adjacent rows two by two extending longitudinally parallel to the longitudinal axis X. The pins 10 of the same row extend in the same way in the same orientation, parallel to each other, from the core 2. Here, considering two adjacent rows, the pins 10 of a adjacent rows are oriented differently from the pins 10 of the other of the adjacent rows, for example, as illustrated in figure 1 , at 180°. Alternatively, the orientation is 90°.

En référence aux figures 3 et 4, nous allons décrire un premier mode de réalisation d'un picot 110 destiné à un dispositif applicateur selon l'invention. Ce picot 110 selon l'invention comporte une extrémité d'ancrage 11 et une extrémité libre 12. L'extrémité d'ancrage 11 est reliée à l'âme 2 du dispositif applicateur selon l'invention. Le picot 110 s'étend donc depuis l'extrémité d'ancrage 11 jusqu'à l'extrémité libre 12, ici globalement dans un plan qui est à la figure 3 la feuille. Depuis l'extrémité d'ancrage 11, le picot 110 selon l'invention comporte un premier tronçon 16 de corps courbé dans un premier sens, puis un deuxième tronçon 18 de corps courbé dans un sens opposé, puis se termine par l'extrémité libre 12. Cela donne une forme en « S » inversé pour le corps du picot 110 selon l'invention tel qu'illustré dans la figure 3. Le premier tronçon 16 de corps est relié au deuxième tronçon 18 de corps au niveau d'une extrémité 20 commune aux deux tronçons de corps. La forme courbée du deuxième tronçon 18 de corps forme une première boucle située au niveau de l'extrémité libre 12.With reference to figures 3 and 4 , we are going to describe a first embodiment of a spike 110 intended for an applicator device according to the invention. This spike 110 according to the invention comprises an anchoring end 11 and a free end 12. The anchoring end 11 is connected to the core 2 of the applicator device according to the invention. The spike 110 therefore extends from the anchoring end 11 to the free end 12, here generally in a plane which is at the picture 3 leaf. From the anchoring end 11, the spike 110 according to the invention comprises a first body section 16 curved in a first direction, then a second body section 18 curved in an opposite direction, then ends with the free end 12. This gives an inverted "S" shape for the body of the pin 110 according to the invention as illustrated in the picture 3 . The first body section 16 is connected to the second body section 18 at an end 20 common to the two body sections. The curved shape of the second body section 18 forms a first loop located at the level of the free end 12.

D'autre part, le picot 110 comporte une extension secondaire 17 qui s'étend en saillie depuis le picot 110, au niveau de l'extrémité commune 20 des deux tronçons 16,18 de corps. Ici, cette extension secondaire s'étend dans le plan du picot 110. Elle forme une deuxième boucle qui s'étend en regard de la première boucle 18 et dont une courbure est opposée à celle de la première boucle. Ainsi, les première et deuxième boucles forment des moyens de captation et de retenue et délimitent en partie un réservoir 14 destiné à recevoir une quantité de produit fluide ou pâteux. Ainsi, la première boucle formée par le deuxième tronçon 18 de corps permet, lors d'une utilisation du dispositif applicateur 1 selon l'invention, et en particulier lors d'un passage à travers un essoreur dudit dispositif 1 selon l'invention, de protéger la quantité de produit fluide ou pâteux reçu dans le réservoir 14 : le picot n'est alors pas déchargé de ladite quantité de produit.On the other hand, the spike 110 includes a secondary extension 17 which projects from the spike 110, at the level of the common end 20 of the two 16.18 body sections. Here, this secondary extension extends in the plane of the pin 110. It forms a second loop which extends opposite the first loop 18 and whose curvature is opposite to that of the first loop. Thus, the first and second loops form capture and retention means and partly delimit a reservoir 14 intended to receive a quantity of fluid or pasty product. Thus, the first loop formed by the second body section 18 makes it possible, when using the applicator device 1 according to the invention, and in particular when passing through a wiper of said device 1 according to the invention, to protect the quantity of fluid or pasty product received in the reservoir 14: the pin is then not discharged from said quantity of product.

De plus, le picot 110 comporte des deuxièmes moyens de captation et de retenue 13, 15, 16 d'une quantité de produit fluide ou pâteux. Ces deuxièmes moyens de captation et de retenue sont positionnés au niveau de l'extrémité d'ancrage 11 du picot 110 , à distance de celui-ci, tout en étant situés en dessous des moyens de captation et de retenue précédemment décrits et positionnés au niveau de l'extrémité libre 12 du picot 110. Les deuxièmes moyens de captation et de retenue comportent ici une première boucle formée par le premier tronçon 16 de corps du picot 110 et une deuxième boucle formée par une deuxième extension secondaire 15 qui s'étend en regard de la première boucle formée par le premier tronçon 16 de corps et dont une courbure est opposée à celle de cette première boucle. L'extension secondaire 15 s'étend en saillie depuis le picot 110, au niveau d'une extrémité inférieure 21 du premier tronçon 16 de corps. Ici, cette deuxième extension secondaire s'étend dans le plan du picot 110. Ainsi, le premier tronçon 16 de corps et la deuxième extension secondaire 15 délimitent en partie un deuxième réservoir 13 destiné à recevoir une quantité de produit fluide ou pâteux. Ainsi, le réservoir 14 est au-dessus du deuxième réservoir 13 dans la direction d'extension du picot 110.In addition, the spike 110 comprises second means 13, 15, 16 for capturing and retaining a quantity of fluid or pasty product. These second capture and retention means are positioned at the level of the anchoring end 11 of the pin 110, at a distance therefrom, while being located below the capture and retention means previously described and positioned at the level of the free end 12 of the spike 110. The second capture and retention means here comprise a first loop formed by the first section 16 of the body of the spike 110 and a second loop formed by a second secondary extension 15 which extends next to the first loop formed by the first section 16 of body and whose curvature is opposite to that of this first loop. The secondary extension 15 projects from the pin 110, at the level of a lower end 21 of the first section 16 of the body. Here, this second secondary extension extends in the plane of the pin 110. Thus, the first body section 16 and the second secondary extension 15 partly delimit a second reservoir 13 intended to receive a quantity of fluid or pasty product. Thus, reservoir 14 is above second reservoir 13 in the direction of extension of spike 110.

En référence maintenant à la figure 5, nous allons décrire une variante 210 de réalisation du picot précédemment décrit et destiné à un dispositif applicateur selon l'invention. Le picot 210 de cette variante comporte depuis l'extrémité d'ancrage 11 vers l'extrémité libre 12, le premier tronçon 216 de corps courbé dans un premier sens, puis le deuxième tronçon 218 de corps courbé dans un sens opposé. De plus, le picot 210 comporte une face latérale 219 s'étendant sur toute la hauteur du picot 210 et venant en appui sur un cercle C. Le cercle C est dans un plan qui est perpendiculaire à l'axe longitudinal X, un point d'intersection de l'axe longitudinal X avec le plan du cercle C est sur le cercle C. Une telle configuration du cercle C supportant une face du picot est décrite en détail dans le document FR 2 937 514 auquel il est possible de se référer pour de plus amples informations.Referring now to the figure 5 , we are going to describe a variant embodiment 210 of the spike previously described and intended for an applicator device according to the invention. The spike 210 of this variant comprises, from the anchoring end 11 towards the free end 12, the first body section 216 curved in a first direction, then the second body section 218 curved in a opposite. In addition, the spike 210 has a side face 219 extending over the entire height of the spike 210 and bearing on a circle C. The circle C is in a plane which is perpendicular to the longitudinal axis X, a point of intersection of the longitudinal axis X with the plane of the circle C is on the circle C. Such a configuration of the circle C supporting a face of the pin is described in detail in the document FR 2 937 514 which can be referred to for further information.

La figure 2 illustre un dispositif applicateur 3 selon l'invention comportant des rangées de picots 210.There picture 2 illustrates an applicator device 3 according to the invention comprising rows of spikes 210.

Nous allons maintenant décrire, en référence aux figures 6 à 8, un deuxième mode de réalisation d'un picot 310 destiné à un dispositif applicateur selon l'invention. Le picot 310 est structurellement similaire au picot 110 précédemment décrit. Le picot 310 se différencie du picot 110 par le fait que les moyens de captation et de retenue comportent, en outre, ici deux ergots latéraux 19, qui s'étendent en saillie du picot 310. Ici, les deux ergots latéraux 19 s'étendent de part et d'autre du plan du picot 310. Les deux ergots latéraux 19 sont implantés au niveau de l'extrémité commune 20 et sont, ici, inclinés vers le haut. Les ergots latéraux 19 délimitent aussi en partie le réservoir 14. En variante de réalisation, le picot 310 ne comporte qu'un seul ergot latéral 19. Dans une autre variante de réalisation, le ou les ergots latéraux 19 s'étendent de manière sensiblement horizontale.We will now describe, with reference to figures 6 to 8 , a second embodiment of a spike 310 intended for an applicator device according to the invention. Pin 310 is structurally similar to pin 110 previously described. The pin 310 differs from the pin 110 in that the capture and retaining means further comprise here two lateral lugs 19, which extend projecting from the pin 310. Here, the two lateral lugs 19 extend on either side of the plane of the pin 310. The two lateral lugs 19 are located at the level of the common end 20 and are, here, inclined upwards. The lateral lugs 19 also partly delimit the reservoir 14. In a variant embodiment, the pin 310 has only one lateral lug 19. In another variant embodiment, the lateral lug(s) 19 extend substantially horizontally .

La figure 9 illustre un dispositif applicateur 4 selon l'invention comportant des rangées de picots 310 et des rangés d'une variante de réalisation des picots 410 qui vont maintenant être brièvement décrits.There figure 9 illustrates an applicator device 4 according to the invention comprising rows of spikes 310 and rows of an alternative embodiment of the spikes 410 which will now be briefly described.

En figures 10 et 11, est illustré un troisième mode de réalisation d'un picot 410 destiné à un dispositif applicateur selon l'invention. Le picot 410 est une variante du picot 310 précédemment décrit. Il s'en différencie par le fait qu'il comporte un seul ergot latéral 419, court et s'étendant de manière sensiblement horizontale. En variante de réalisation, l'ergot latéral 419 est similaire à l'ergot latéral 19 du mode de réalisation précédente du picot 310.In figures 10 and 11 , is illustrated a third embodiment of a spike 410 intended for an applicator device according to the invention. Pin 410 is a variant of pin 310 previously described. It differs from it in that it comprises a single lateral lug 419, which is short and extends substantially horizontally. In a variant embodiment, the lateral lug 419 is similar to the lateral lug 19 of the previous embodiment of the pin 310.

La figure 12 illustre un dispositif applicateur 5 selon l'invention comportant des rangées de picots 110 et des rangés d'une variante de réalisation des picots 410. La figure 13 illustre un dispositif applicateur 6 selon l'invention comportant des rangées de picots 410 et des rangés de picots 110 selon un autre agencement. D'autres types de picots selon l'invention peuvent être utilisés et associés.There figure 12 illustrates an applicator device 5 according to the invention comprising rows of spikes 110 and rows of a variant embodiment of the spikes 410. The figure 13 illustrates an applicator device 6 according to the invention comprising rows of spikes 410 and rows of spikes 110 according to another arrangement. Other types of pins according to the invention can be used and combined.

Les figures 14 à 16 illustrent un quatrième mode de réalisation d'un picot 510 destiné à un dispositif applicateur selon l'invention. Le picot 510 se différencie du picot 110 précédemment décrit par le fait qu'il comporte un ergot latéral 519 qui s'étend en saillie depuis le deuxième tronçon 518 de corps du picot 510, et ce à distance de l'extrémité libre 12 et de l'extrémité commune 20, en particulier sensiblement à mi-distance de ces deux extrémités. L'ergot latéral 519 s'étend sensiblement de manière horizontale et en direction du réservoir 14. Afin de garder une certaine flexibilité du deuxième tronçon 518 de corps au niveau de l'implantation de l'ergot latéral 519, une encoche 520 est prévue dans l'épaisseur du tronçon 518, au droit de l'ergot latéral 519.THE figures 14 to 16 illustrate a fourth embodiment of a spike 510 intended for an applicator device according to the invention. The spike 510 differs from the spike 110 previously described in that it includes a lateral lug 519 which projects from the second body section 518 of the spike 510, and this at a distance from the free end 12 and from the common end 20, in particular substantially halfway between these two ends. The lateral lug 519 extends substantially horizontally and in the direction of the reservoir 14. In order to retain a certain flexibility of the second section 518 of the body at the level of the implantation of the lateral lug 519, a notch 520 is provided in the thickness of the section 518, in line with the lateral lug 519.

Dans une variante de réalisation, est illustré en figure 17 un picot 610 destiné à un dispositif applicateur selon l'invention. Le picot 610 se différencie du picot 510 précédent par le fait que l'ergot latéral 619 est plus fin et s'étend en saillie depuis le picot de manière sensiblement horizontale et perpendiculaire au plan du picot 610, de manière similaire à l'ergot latéral 419 du picot 410 précédemment décrit. Du fait de la finesse et de l'implantation de l'ergot latéral 619, il n'est plus nécessaire de prévoir une encoche dans l'épaisseur du deuxième tronçon 18 de corps.In a variant embodiment, is illustrated in figure 17 a spike 610 intended for an applicator device according to the invention. The pin 610 differs from the previous pin 510 in that the lateral lug 619 is thinner and extends projecting from the pin in a substantially horizontal manner and perpendicular to the plane of the pin 610, similarly to the lateral lug 419 of the pin 410 previously described. Due to the thinness and location of the lateral lug 619, it is no longer necessary to provide a notch in the thickness of the second section 18 of the body.

En figures 18 à 20, un cinquième mode de réalisation d'un picot 710 destiné à un dispositif applicateur selon l'invention est illustré. C'est une variante de réalisation du picot 110 précédemment décrit. Le picot 710 se différencie du picot 110 par le fait que les extensions secondaires 715 et 717 sont de tailles différentes de celle des extensions secondaires 15 et 17 respectivement. En particulier, les extensions secondaires 717 et 715 sont plus longues et permettent ainsi d'adapter les moyens de captation et de retenue pour des produits à faible viscosité, donc plutôt fluides.In figures 18 to 20 , a fifth embodiment of a spike 710 intended for an applicator device according to the invention is illustrated. This is a variant embodiment of the pin 110 previously described. The pin 710 differs from the pin 110 in that the secondary extensions 715 and 717 are of different sizes from that of the secondary extensions 15 and 17 respectively. In particular, the secondary extensions 717 and 715 are longer and allow thus to adapt the capture and retention means for products with low viscosity, therefore rather fluid.

Il est à noter que dans les modes de réalisation précédemment décrits, les ergots latéraux, faisant parties des moyens de captation et de retenue, permettent aussi de délimiter en partie le réservoir 14 et d'améliorer le prélèvement et la retenue de la quantité de produit fluide ou pâteux.It should be noted that in the embodiments described above, the side lugs, forming part of the capture and retention means, also make it possible to partially delimit the reservoir 14 and to improve the removal and retention of the quantity of product fluid or pasty.

De manière similaire, il est possible de prévoir des ergots latéraux identiques à ceux décrits précédemment au niveau du deuxième réservoir 13 et qui font partie des deuxièmes moyens de captation et de retenue.Similarly, it is possible to provide lateral lugs identical to those previously described at the level of the second reservoir 13 and which form part of the second capture and retention means.

De manière générale, quel que soit le mode de réalisation du dispositif applicateur selon l'invention, au moins l'âme 2 et les picots sont venus de matière l'une avec les autres de sorte à former une pièce monobloc. L'âme et les picots sont réalisés en un ou plusieurs matériaux du type thermoplastique, thermoplastique élastomère ou matière vulcanisable, ayant des propriétés physiques différentes. D'autre part, l'âme et les picots sont obtenus à l'aide d'un procédé de moulage ou d'un procédé d'addition de matière, par exemple, de type stéréo lithographie ou impression tridimensionnelle.In general, whatever the embodiment of the applicator device according to the invention, at least the core 2 and the spikes are integral with each other so as to form a single piece. The core and the pins are made of one or more materials of the thermoplastic, elastomeric thermoplastic or vulcanizable type, having different physical properties. On the other hand, the core and the spikes are obtained using a molding process or a material addition process, for example, of the stereo lithography or three-dimensional printing type.
