Description

DISPOSITIF APPLICATEUR D’UN PRODUIT FLUIDE  APPLICATOR DEVICE FOR A FLUID PRODUCT
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
[0001] 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 hair, eyelashes, eyebrows, skin or lips.
ETAT DE LA TECHNIQUE ANTERIEURE STATE OF THE PRIOR ART
[0002] 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 monolithiques et leur extrémité encastrée dans l’âme présente une section plus importante qu’une section du picot au niveau de son extrémité libre, en particulier pour des raisons de techniques de moulage. De ce fait, le picot quel que soit le matériau utilisé est relativement peu flexible. En effet, le picot va, lors d’une utilisation du dispositif applicateur, opposer une certaine résistance lorsque celui-ci entre en contact frontal ou latéral avec une fibre kératinique (ou un épiderme). En conséquence, le picot va 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 are currently devices for applying a product of the fluid or pasty type to keratin fibers, such as mascara brushes for example, comprising a central core of elongated shape extending along a longitudinal axis, at least one row. elongated pins comprising a first end embedded in the core and a second free end. Usually the pins and the core are formed from a single piece of molding, made from one another. For example, document FR 2 937 514 describes such applicator devices. A drawback of this type of embodiment is that the pins are monolithic and their end embedded in the core has a larger section than a section of the pin at its free end, in particular for reasons of molding techniques. Therefore, the pin whatever the material used is relatively inflexible. Indeed, the pin will, when using the applicator device, put up a certain resistance when it comes into frontal or lateral contact with a keratin fiber (or an epidermis). Consequently, the picot will bite, for example, the eyelid during an eyelash make-up, or else the skin during an eyebrow treatment, or else the lips or the scalp ...
[0003] Une première solution à cette problématique de confort est apportée par le document US2012/0170965 qui décrit un picot comprenant une extrémité d’ancrage conique de section toujours aussi importante que précédemment, ainsi qu’une extrémité libre très souple qui peut être recourbée de sorte à ce que la pointe ne vienne pas piquer l’épiderme. Toutefois, cette solution présente deux inconvénients. Le premier est que la flexibilité de l’extrémité libre ainsi que le fait qu’elle soit recourbée ne permettent plus de démêler les fibres kératiniques lors d’une application. L’autre inconvénient est que la base du picot étant rigide, le produit présent entre les bases rigides du picot ne peut remonter vers l’extrémité libre des picots pour être appliqué sur les fibres kératiniques ou l’épiderme. A first solution to this problem of comfort is provided by document US2012 / 0170965 which describes a pin comprising an end conical anchoring section still as large as before, as well as a very flexible free end which can be bent so that the point does not come to prick the epidermis. However, this solution has two drawbacks. The first is that the flexibility of the free end as well as the fact that it is bent no longer makes it possible to untangle the keratin fibers during an application. The other drawback is that the base of the pin being rigid, the product present between the rigid bases of the pin cannot rise towards the free end of the pins to be applied to the keratin fibers or the epidermis.
EXPOSE DE L’INVENTION STATEMENT OF THE INVENTION
[0004] 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.
[0005]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, caractérisé en ce que chaque picot comporte, depuis l’extrémité d’ancrage vers l’extrémité libre, un étage proximal, un pont et un étage distal, l’un au moins parmi l’étage proximal et le pont formant une liaison flexible. To this end, there is provided, according to the invention, 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 longitudinal cylindrical shape, a plurality of pins distributed over said core, each pin extending from an anchoring end in the core towards a free end and having come integrally with said core, characterized in that each pin comprises , from the anchoring end to the free end, a proximal stage, a bridge and a distal stage, at least one of the proximal stage and the bridge forming a flexible connection.
[0006]Ainsi, une telle structure du picot permet de conserver un étage distal suffisamment rigide pour permettre de démêler les fibres kératiniques tout en les guidant, la liaison flexible formée par l’étage proximal et/ou le pont servant d’amortisseur permettant de gommer la sensation de piqûre lorsque l’extrémité libre du picot vient en contact avec la peau sous-jacente.

DESCRIPTION DETAILLEE D’UN MODE DE REALISATION DETAILED DESCRIPTION OF AN EMBODIMENT
[0010] En référence à la figure 15, nous allons décrire un premier mode de réalisation d’un dispositif applicateur 1 selon l’invention. 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. Referring to Figure 15, we will describe a first embodiment of an applicator device 1 according to the invention. The applicator device 1 according to the invention is, here, a mascara brush. Here it comprises a core 2 which extends longitudinally along a longitudinal axis X. The core 2 may have a constant cross section 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 engaged with a tube and / or a gripping handle to a free distal end. In general, the core 2 is of generally cylindrical shape, preferably of axis revolution of the longitudinal axis X. Thus, the cross section of the core 2 can have a circular, polygonal, oval or other shape. It can be axisymmetric. Core 2 can be solid or hollow. The person skilled in the art will choose the most appropriate soul according to economic and / or technical constraints.
[0011] 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, par exemple, 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 15, 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 pins 10 distributed on the core 2. The pins 10 extend in projection from an external peripheral surface of the core 2. The pins 10 are, for example, made in one piece with the core 2. In particular, the pins 10 are obtained by molding with the core 2. Here, illustrated, the pins 10 are distributed in adjacent rows two by two extending longitudinally of parallel to the axis longitudinal X. The pins 10 of the same row extend in the same way in the same orientation, parallel to one another, from the core 2. Here, considering two adjacent rows, the pins 10 of one of the adjacent rows are oriented differently from the pins 10 of the other of the adjacent rows, for example, as illustrated in FIG. 15, at 180 °. Alternatively, the orientation is 90 °.
[0012] En référence à la figure 1 , nous allons décrire plus en détail, un premier mode de réalisation d’un picot 10 pour un dispositif applicateur 1 selon l’invention. Le picot 10 comporte une extrémité d’ancrage 14 et une extrémité libre 12. L’extrémité d’ancrage 14 est reliée à l’âme 2 du dispositif applicateur 1 selon l’invention. Le picot 10 s’étend donc depuis l’extrémité d’ancrage 14 jusqu’à l’extrémité libre 12, ici dans un plan P de symétrie. Depuis l’extrémité d’ancrage 14, le picot 10 comporte un étage proximal 13 suivit d’un pont 15 puis d’un étage distal 11 se terminant par l’extrémité libre 12. Le pont 15 sert de jonction entre les étages proximal 13 et distal 11. L’étage distal 11 comporte ici une extension principale de forme tronconique. L’étage proximal 13 est, ici, de forme incurvée comme une crosse, dont un apex est ici situé à distance du pont 15 qui se trouve alors à une hauteur inférieure de celle de l’apex. En variante, le pont 15 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 13. Cette forme incurvée de l’étage proximal 13 permet de donner une certaine flexibilité à l’étage proximal 13. Ainsi l’étage proximal 13 forme une liaison flexible entre l’extrémité d’ancrage 14 (et donc l’âme 2 du dispositif applicateur 1 selon l’invention) et le pont 15. Referring to Figure 1, we will describe in more detail, a first embodiment of a pin 10 for an applicator device 1 according to the invention. The pin 10 has an anchoring end 14 and a free end 12. The anchoring end 14 is connected to the core 2 of the applicator device 1 according to the invention. The pin 10 therefore extends from the anchoring end 14 to the free end 12, here in a plane P of symmetry. From the anchoring end 14, the pin 10 has a proximal stage 13 followed by a bridge 15 then a distal stage 11 ending in the free end 12. The bridge 15 serves as a junction between the proximal stages 13 and distal 11. The distal stage 11 here comprises a main extension of frustoconical shape. The proximal stage 13 is, here, of curved shape like a stick, of which an apex is here located at a distance from the bridge 15 which is then at a height lower than that of the apex. As a variant, the bridge 15 is situated at the apex of the curved shape of the proximal stage 13. This curved shape of the proximal stage 13 makes it possible to give a certain flexibility to the proximal stage 13. Thus the proximal stage 13 forms a flexible connection between the anchoring end 14 (and therefore the core 2 of the applicator device 1 according to the invention) and the bridge 15.
[0013] Selon différentes variantes de réalisation, le pont 15 étant positionné sur une extrémité libre de la forme incurvée de l’étage proximal 13, cette extrémité libre de la forme incurvée de l’étage proximal 13 forme un tablier selon une direction qui peut être parallèle à l’axe X (c’est-à-dire que le pont 15 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 13), ou bien selon une direction qui le rapproche de l’axe X (le pont 15 est situé à une hauteur inférieure de celle de l’apex de la forme incurvée de l’étage proximal 13), ou bien au contraire selon une direction qui l’éloigne de l’axe X. [0014] Selon une variante de réalisation du picot 10, illustrée à la figure 2, l’étage proximal 113 du picot 110 est en forme d’arc de cercle de l’ordre d’un quart d’arc de cercle. According to different alternative embodiments, the bridge 15 being positioned on a free end of the curved shape of the proximal stage 13, this free end of the curved shape of the proximal stage 13 forms an apron in a direction which can be parallel to the X axis (that is to say that the bridge 15 is located at the apex of the curved shape of the proximal stage 13), or else in a direction which brings it closer to the X axis (the bridge 15 is located at a lower height than that of the apex of the curved shape of the proximal stage 13), or on the contrary in a direction which moves it away from the X axis. According to an alternative embodiment of the pin 10, illustrated in FIG. 2, the proximal stage 113 of the pin 110 is in the form of an arc of a circle of the order of a quarter of an arc of a circle.
[0015] Selon une deuxième variante de réalisation du picot 10, illustrée à la figureAccording to a second alternative embodiment of the pin 10, illustrated in Figure
3, l’étage proximal 213 du picot 210 est aminci et présente une face plane 201 comprise dans le plan P de symétrie. Cette face plane 201 se poursuit dans le pont 215 apportant à ce dernier une certaine flexibilité venant s’ajouter à celle de l’étage proximal 213. De nouveau, comme pour le pont 15, selon différentes variantes de réalisation, le pont 215 étant positionné sur une extrémité libre de la forme incurvée de l’étage proximal 213, cette extrémité libre de la forme incurvée de l’étage proximal 213 forme un tablier selon une direction qui peut être parallèle à l’axe X (c’est-à-dire que le pont 215 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 213), ou bien selon une direction qui le rapproche de l’axe X (le pont 215 est situé à une hauteur inférieure de celle de l’apex de la forme incurvée de l’étage proximal 213), ou bien au contraire selon une direction qui l’éloigne de l’axe X. 3, the proximal stage 213 of the pin 210 is thinned and has a flat face 201 included in the plane P of symmetry. This flat face 201 continues in the bridge 215 bringing to the latter a certain flexibility which is added to that of the proximal stage 213. Again, as for the bridge 15, according to different variant embodiments, the bridge 215 being positioned on a free end of the curved form of the proximal stage 213, this free end of the curved form of the proximal stage 213 forms an apron in a direction which can be parallel to the axis X (i.e. say that the bridge 215 is located at the apex of the curved shape of the proximal stage 213), or else in a direction which brings it closer to the axis X (the bridge 215 is located at a lower height than that of the apex of the curved shape of the proximal stage 213), or on the contrary in a direction which moves it away from the axis X.
[0016] Selon une troisième variante de réalisation du picot 10, illustrée à la figureAccording to a third alternative embodiment of the pin 10, illustrated in Figure
4, l’étage proximal 313 du picot 310 est aminci comme précédemment et présente une face plane 301 comprise dans le plan P de symétrie. D’autre part, l’étage distal 311 est lui aminci et présente une face plane 302 aussi comprise dans le plan P de symétrie. L’agencement est tel que l’étage proximal 313 s’étend d’un côté du plan P de symétrie alors que l’étage distal 311 s’étend de l’autre côté du plan P de symétrie. D’autre part, la face plane 302 se poursuit dans le pont 315 apportant à ce dernier une certaine flexibilité venant s’ajouter à celle de l’étage proximal 313. De nouveau, comme pour le pont 15,215, selon différentes variantes de réalisation, le pont 315 étant positionné sur une extrémité libre de la forme incurvée de l’étage proximal 313, cette extrémité libre de la forme incurvée de l’étage proximal 313 forme un tablier selon une direction qui peut être parallèle à l’axe X (c’est-à-dire que le pont 315 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 313), ou bien selon une direction qui le rapproche de l’axe X (le pont 315 est situé à une hauteur inférieure de celle de l’apex de la forme incurvée de l’étage proximal 313), ou bien au contraire selon une direction qui l’éloigne de l’axe X. 4, the proximal stage 313 of the pin 310 is thinned as above and has a flat face 301 included in the plane P of symmetry. On the other hand, the distal stage 311 is thinned and has a planar face 302 also included in the plane P of symmetry. The arrangement is such that the proximal stage 313 extends on one side of the plane P of symmetry while the distal stage 311 extends on the other side of the plane P of symmetry. On the other hand, the planar face 302 continues in the bridge 315 bringing to the latter a certain flexibility which is added to that of the proximal stage 313. Again, as for the bridge 15,215, according to different variant embodiments, the bridge 315 being positioned on a free end of the curved shape of the proximal stage 313, this free end of the curved shape of the proximal stage 313 forms an apron in a direction which can be parallel to the axis X (c that is to say that the bridge 315 is located at the apex of the curved shape of the proximal stage 313), or else in a direction which brings it closer to the axis X (the bridge 315 is located at a lower height than that of the apex of the curved shape of the proximal stage 313), or on the contrary in a direction which moves it away from the axis X.
[0017] En figure 5 est illustrée une quatrième variante de réalisation du picot 10. Le picot 410 se différencie du picot 10 en ce qu’il comporte un étage distal 11 dont l’extension principale est orientée de sorte à former un angle avec le plan P de symétrie. En variante 411 illustrée à la figure 6, l’extension principale est dans le plan P de symétrie mais présente un angle avec une verticale. De manière plus générale, dans cette variante de réalisation, l’extension principale présente une orientation contenue dans un cône d’angle au sommet 2 , sommet situé ici au niveau du pont 15. In Figure 5 is illustrated a fourth alternative embodiment of the pin 10. The pin 410 differs from the pin 10 in that it comprises a distal stage 11 whose main extension is oriented so as to form an angle with the plane P of symmetry. In a variant 411 illustrated in FIG. 6, the main extension is in the plane P of symmetry but has an angle with a vertical. More generally, in this variant embodiment, the main extension has an orientation contained in a corner cone at the apex 2, apex located here at the level of the bridge 15.
[0018] En figures 7 à 9, une cinquième variante du picot 10, ainsi que des déclinaisons sont illustrées. Le picot 101 comporte un étage distal comprenant une extension principale 11 a et une extension secondaire 11 b s’étendant en saillie depuis le pont 15 et formant un angle l’une avec l’autre. Le picot 102 comporte un étage distal comprenant une extension principale 11 a et une extension secondaire 17 s’étendant en saillie depuis une paroi latérale de l’extension principale 11 a. Le picot 103 comporte un étage distal comprenant une extension principale 11 a et une extension secondaire 18 s’étendant en saillie depuis l’étage proximal 13. In Figures 7 to 9, a fifth variant of the pin 10, as well as variations are illustrated. The pin 101 has a distal stage comprising a main extension 11 a and a secondary extension 11 b extending from the bridge 15 and forming an angle with one another. The pin 102 has a distal stage comprising a main extension 11a and a secondary extension 17 extending projecting from a side wall of the main extension 11a. The pin 103 has a distal stage comprising a main extension 11 a and a secondary extension 18 extending projecting from the proximal stage 13.
[0019] Une sixième variante de réalisation du picot 10 est illustrée en figure 10. Le picot 104 comporte en outre, au niveau de son étage proximal 13, un pied flexible 16 s’étendant entre le pont 15 et l’âme 2 et supportant l’étage distal 11 . La flexibilité du pied flexible 16 est telle que l’étage proximal 13 forme toujours une liaison flexible entre le pont 15 et l’extrémité d’ancrage 14 lors d’un appui sur l’extrémité libre 12 du picot 104. Toutefois, le pied flexible 16 retient le picot 104 en évitant que ce dernier ne s’allonge ou ne bascule en arrière lorsque, lors d’une utilisation, le picot 104 vient en contact au niveau de son extrémité libre 12 avec une lèvre d’un essoreur d’un tube contenant le produit fluide et dans lequel est stocké le dispositif applicateur 1 selon l’invention. Les figures 11 et 12 illustrent des variantes de réalisation 105 et 106 des picots 102 et 101 respectivement comportant le pied flexible 16. [0020] En figure 13, est illustrée une septième variante de réalisation du picot 10. Le picot 510 de cette variante comporte depuis l’extrémité d’ancrage 14 vers l’extrémité libre 12, l’étage proximal 513, le pont 515 et l’étage distal 511 . De plus, le picot 510 comporte une face latérale 514 s’étendant sur toute la hauteur du picot 510 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 et 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 ample information. A sixth alternative embodiment of the pin 10 is illustrated in Figure 10. The pin 104 further comprises, at its proximal stage 13, a flexible foot 16 extending between the bridge 15 and the core 2 and supporting distal stage 11. The flexibility of the flexible foot 16 is such that the proximal stage 13 always forms a flexible connection between the bridge 15 and the anchoring end 14 when the free end 12 of the pin 104 is pressed. However, the foot flexible 16 retains the pin 104, preventing the latter from elongating or tilting back when, during use, the pin 104 comes into contact at its free end 12 with a lip of a wringer a tube containing the fluid product and in which the applicator device 1 according to the invention is stored. FIGS. 11 and 12 illustrate alternative embodiments 105 and 106 of the pins 102 and 101 respectively comprising the flexible foot 16. In Figure 13, a seventh alternative embodiment of the pin 10 is illustrated. The pin 510 of this variant comprises, from the anchoring end 14 towards the free end 12, the proximal stage 513, the bridge 515 and distal stage 511. In addition, the pin 510 has a lateral face 514 extending over the entire height of the pin 510 and coming to bear on a circle C. The circle C is in a plane which is perpendicular to the longitudinal axis X, a point d intersection of the longitudinal axis X with the plane of circle C and on circle C. Such a configuration of circle C supporting one face of the pin is described in detail in document FR 2 937 514 to which it is possible to refer for further information.
[0021] De nouveau, comme pour le pont 15,215,315, selon différentes variantes de réalisation, le pont 515 étant positionné sur une extrémité libre de la forme incurvée de l’étage proximal 513, cette extrémité libre de la forme incurvée de l’étage proximal 513 forme un tablier selon une direction qui peut être parallèle à l’axe X (c’est-à-dire que le pont 515 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 513), ou bien selon une direction qui le rapproche de l’axe X (le pont 515 est situé à une hauteur inférieure de celle de l’apex de la forme incurvée de l’étage proximal 513), ou bien au contraire selon une direction qui l’éloigne de l’axe X. Again, as for the bridge 15,215,315, according to different alternative embodiments, the bridge 515 being positioned on a free end of the curved shape of the proximal stage 513, this free end of the curved form of the proximal stage 513 forms an apron in a direction which can be parallel to the axis X (that is to say that the bridge 515 is situated at the level of the apex of the curved shape of the proximal stage 513), or else in a direction which brings it closer to the X axis (the bridge 515 is situated at a height lower than that of the apex of the curved shape of the proximal stage 513), or on the contrary in a direction which moves it away of the X axis.
[0022] Une huitième variante de réalisation du picot 10 est illustrée en figure 14. Le picot 610 de cette variante de réalisation comporte depuis l’extrémité d’ancrage 14 vers l’extrémité libre 12, l’étage proximal 613, le pont 615 et l’étage distal 611. La différence principale vient du fait que l’extrémité d’ancrage 14 est ici située sensiblement à la verticale du pont 615 donnant au picot 610 une forme proche d’un « S » déformé en vue de côté (figure 14a). En vue de face (figure 14b) le picot 610 est contenu dans le plan P de symétrie. An eighth alternative embodiment of the pin 10 is illustrated in FIG. 14. The pin 610 of this alternative embodiment comprises, from the anchoring end 14 towards the free end 12, the proximal stage 613, the bridge 615 and the distal stage 611. The main difference comes from the fact that the anchoring end 14 is here situated substantially vertical to the bridge 615 giving the pin 610 a shape close to a deformed "S" in side view ( Figure 14a). In front view (FIG. 14b) the pin 610 is contained in the plane P of symmetry.
[0023] En figures 37 et 38 est illustré une implantation d’une pluralité de picots 610 dans un mode de réalisation d’un dispositif applicateur 5 selon l’invention. Comme indiqué précédemment, les picots 610 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 le plan P de symétrie des picots 610 est sensiblement perpendiculaire à l’axe longitudinal X. De nouveau, en considérant deux rangées adjacentes, les picots 610 d’une des rangées adjacentes sont orientés de manière différente des picots 610 de l’autre des rangées adjacentes, à 180°, tout en étant décalés longitudinalement d’une rangée adjacente à l’autre. Ainsi, en vue de face illustrée à la figure 38, le dispositif applicateur 5 selon l’invention présente une série de lobes (ici au nombre de cinq) uniformément répartie sur une circonférence de l’âme 2. In Figures 37 and 38 is illustrated an implantation of a plurality of pins 610 in an embodiment of an applicator device 5 according to the invention. As indicated above, the pins 610 of the same row extend in the same way in the same orientation, parallel to each other, from the core 2: here the plane P of symmetry of the pins 610 is substantially perpendicular to the longitudinal axis X. Again, considering two rows adjacent, the pins 610 of one of the adjacent rows are oriented differently from the pins 610 of the other of the adjacent rows, at 180 °, while being offset longitudinally from one row adjacent to the other. Thus, in front view illustrated in FIG. 38, the applicator device 5 according to the invention has a series of lobes (here five in number) uniformly distributed over a circumference of the core 2.
[0024] En figure 40 est illustrée une autre implantation d’une pluralité de picots 610 dans un mode de réalisation d’un dispositif applicateur 7 selon l’invention. Comme indiqué précédemment, les picots 610 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 le plan P de symétrie des picots 610 passe sensiblement par l’axe longitudinal X. De nouveau, en considérant deux rangées adjacentes, les picots 610 d’une des rangées adjacentes sont orientés de manière différente des picots 610 de l’autre des rangées adjacentes, à 180°. FIG. 40 illustrates another layout of a plurality of pins 610 in an embodiment of an applicator device 7 according to the invention. As indicated above, the pins 610 in the same row extend in the same way in the same orientation, parallel to each other, from the core 2: here the plane P of symmetry of the pins 610 passes substantially through the longitudinal axis X. Again, considering two adjacent rows, the pins 610 from one of the adjacent rows are oriented differently from the pins 610 from the other of the adjacent rows, at 180 °.
[0025] En figure 41 est illustrée une implantation similaire d’une pluralité de picots 110 dans un mode de réalisation d’un dispositif applicateur 8 selon l’invention. In Figure 41 is illustrated a similar layout of a plurality of pins 110 in an embodiment of an applicator device 8 according to the invention.
[0026] Nous allons maintenant décrire un deuxième mode de réalisation d’un picot 710 pour un dispositif applicateur selon l’invention en référence aux figures 16 à 22. Le picot 710 se différencie du picot 10 précédemment décrit en ce que l’étage proximal comporte une arche réalisée par deux formes incurvées 713 symétriques en miroir l’une de l’autre. Ici, chacune des formes incurvées 713 est similaire à l’étage proximal 13 du picot 10 précédemment décrit. Le pont 715 est situé à une jonction des deux formes incurvées 713 formant chacune un pied d’ancrage s’étendant depuis l’extrémité d’ancrage 14. L’étage distal 11 s’étend depuis le pont 715 vers l’extrémité libre 12. We will now describe a second embodiment of a pin 710 for an applicator device according to the invention with reference to Figures 16 to 22. The pin 710 differs from the pin 10 previously described in that the proximal stage comprises an arch formed by two curved shapes 713 symmetrical in mirror of one another. Here, each of the curved shapes 713 is similar to the proximal stage 13 of the pin 10 previously described. The bridge 715 is located at a junction of the two curved forms 713 each forming an anchoring foot extending from the anchoring end 14. The distal stage 11 extends from the bridge 715 towards the free end 12 .
[0027] En première variante de réalisation illustrée à la figure 17, le picot 720 comporte une arche 723 amincie qui présente une face plane 726 comprise dans le plan P de symétrie. Cette face plane 726 se poursuit dans le pont 725 apportant à ce dernier une certaine flexibilité venant s’ajouter à celle de l’étage proximal. [0028] En deuxième variante de réalisation illustrée à la figure 18, le picot 730 comporte une arche formée de deux formes incurvées 733 et 734 amincies qui présentent chacune une face plane 726 et 736 respectivement comprise dans le plan P de symétrie. L’agencement est tel que l’une 733 des formes incurvées s’étend d’un côté du plan P de symétrie alors que l’autre 734 des formes incurvées s’étend de l’autre côté du plan P de symétrie. In the first alternative embodiment illustrated in Figure 17, the pin 720 has a thinned arch 723 which has a flat face 726 included in the plane P of symmetry. This planar face 726 continues in the bridge 725 providing the latter with a certain flexibility which is added to that of the proximal stage. In a second variant illustrated in FIG. 18, the pin 730 comprises an arch formed by two curved shapes 733 and 734 thinned, which each have a plane face 726 and 736 respectively included in the plane P of symmetry. The arrangement is such that one 733 of the curved shapes extends from one side of the plane P of symmetry while the other 734 of the curved shapes extends from the other side of the plane P of symmetry.
[0029] De nouveau, comme pour le pont 15,215,315, selon différentes variantes de réalisation, le pont 715,725 étant positionné sur une extrémité libre de la forme incurvée de l’étage proximal 713,723,733,734, cette extrémité libre de la forme incurvée de l’étage proximal 713,723,733,734 forme un tablier selon une direction qui peut être parallèle à l’axe X (c’est-à-dire que le pont 715,725 est situé au niveau de l’apex de la forme incurvée de l’étage proximal 713,723,733,734), ou bien selon une direction qui le rapproche de l’axe X (le pont 715,725 est situé à une hauteur inférieure de celle de l’apex de la forme incurvée de l’étage proximal 713,723,733,734), ou bien au contraire selon une direction qui l’éloigne de l’axe X Again, as for the bridge 15,215,315, according to different embodiments, the bridge 715,725 being positioned on a free end of the curved form of the proximal stage, this free end of the curved form of the proximal stage 713,723,733,734 forms an apron in a direction which can be parallel to the axis X (that is to say that the bridge 715,725 is situated at the level of the apex of the curved shape of the proximal stage 713,723,733,734), or else in a direction which brings it closer to the X axis (the bridge 715,725 is situated at a lower height than that of the apex of the curved shape of the proximal stage 713,723,733,734), or on the contrary in a direction which distances it of the X axis
[0030] En figures 19 et 20, nous avons illustré une implantation d’une pluralité de picots 710 sur un dispositif applicateur 3 selon l’invention. Comme indiqué précédemment, les picots 710 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. Par exemple, les rangées du haut et du bas comporte des picots 710 dont le plan P de symétrie est sensiblement perpendiculaire à l’axe longitudinal X. Alors que les picots 710 des rangées adjacentes à ces deux rangées du haut et du bas sont orientés à 90°, leur plan P de symétrie passant sensiblement par l’axe longitudinal X de l’âme 2. D’autre part, les picots 710 sont agencés de sorte à ce que trois picots 710 adjacents, un de la rangée du haut et deux d’une des rangées adjacentes, ont un pied d’ancrage commun 713a. En variante de réalisation, ce pied d’ancrage commun 713b est raccourci de sorte à ce que, au repos, il s’étende à distance et en regard d’une surface périphérique de l’âme comme illustré à la figure 21 sur un dispositif applicateur 3a selon l’invention. Dans ce cas, le pied d’ancrage 713b sert de butée d’appui permettant de modifier la flexibilité des picots 716 ayant ce pied d’ancrage commun 713b au cours d’une utilisation du dispositif applicateur 3a selon l’invention. Dans une autre variante de réalisation du dispositif applicateur 3b selon l’invention illustrée en figure 22, le pied d’ancrage commun 713c est réduit à une simple jonction entre les picots 718. Il est possible de mélanger dans une même implantation les pieds d’ancrages commun 713a, 713b et 713c des picots 710, 716, 717 et 718. Cela permet de moduler la flexibilité des picots du dispositif applicateur selon l’invention. In Figures 19 and 20, we illustrated an implementation of a plurality of pins 710 on an applicator device 3 according to the invention. As indicated above, the pins 710 in the same row extend in the same way in the same orientation, parallel to one another, from the core 2. For example, the top and bottom rows have pins 710 whose plane P of symmetry is substantially perpendicular to the longitudinal axis X. While the pins 710 of the rows adjacent to these two rows of top and bottom are oriented at 90 °, their plane P of symmetry passing substantially through l longitudinal axis X of the core 2. On the other hand, the pins 710 are arranged so that three adjacent pins 710, one from the top row and two from one of the adjacent rows, have a foot common anchor 713a. In an alternative embodiment, this common anchoring foot 713b is shortened so that, at rest, it extends at a distance and facing a peripheral surface of the core as illustrated in FIG. 21 on a device applicator 3a according to the invention. In this case, the anchoring foot 713b serves as a support stop enabling the flexibility of the pins 716 having this common anchoring foot 713b to be modified during use of the applicator device 3a according to the invention. In an other variant embodiment of the applicator device 3b according to the invention illustrated in FIG. 22, the common anchoring foot 713c is reduced to a simple junction between the pins 718. It is possible to mix in the same layout the common anchoring feet 713a , 713b and 713c of the pins 710, 716, 717 and 718. This makes it possible to modulate the flexibility of the pins of the applicator device according to the invention.
[0031] Maintenant, nous allons décrire un troisième mode de réalisation d’un picot pour un dispositif applicateur 4 selon l’invention, en référence aux figures 23 à 26. Le picot 1010 comporte, depuis l’extrémité d’ancrage 14, un étage proximal 1013, un pont 1015 et un étage distal 11 ,1011 s’étendant jusqu’à l’extrémité libre 12. L’extrémité distal comporte ici une extension principale 11 s’étendant depuis le pont 1015 et une extrémité secondaire 1011 s’étendant depuis le pont 1015 le long et à distance de l’extension principale 11. Ici, c’est le pont 1015 qui forme la liaison flexible entre les étages proximal 1013 et distal 11 ,1011. L’extension secondaire 1011 forme un angle dans le plan P de symétrie avec l’extension principale 11. En variante du picot 1010b, illustrée en figure 26, l’extension secondaire 1011 b forme aussi un angle avec le plan P de symétrie. Now we will describe a third embodiment of a pin for an applicator device 4 according to the invention, with reference to Figures 23 to 26. The pin 1010 has, from the anchoring end 14, a proximal stage 1013, a bridge 1015 and a distal stage 11, 1011 extending to the free end 12. The distal end here comprises a main extension 11 extending from the bridge 1015 and a secondary end 1011 s' extending from the bridge 1015 along and at a distance from the main extension 11. Here, it is the bridge 1015 which forms the flexible connection between the proximal 1013 and distal stages 11, 1011. The secondary extension 1011 forms an angle in the plane P of symmetry with the main extension 11. As a variant of the pin 1010b, illustrated in FIG. 26, the secondary extension 1011 b also forms an angle with the plane P of symmetry.
[0032] En figures 23 et 24, une implantation d’une pluralité de picots 1010 et 1010b dans un mode de réalisation d’un dispositif applicateur 4 selon l’invention est représentée. Ici, les picots 1010 forment une première rangée longitudinale alors que les picots 1010b forment une deuxième rangée longitudinale adjacente à la première. Ici, les picots 1010 sont orientés dans le même sens, leurs plan P de symétrie étant perpendiculaire à l’axe longitudinal X, et les picots 1010b sont orientés à 90° par rapport aux picots 1010, leur plan P de symétrie passant par l’axe longitudinal X. D’autres implantations sont possibles s’inspirant de celles déjà décrites précédemment en relation avec d’autres modes de réalisation des picots. In Figures 23 and 24, an implantation of a plurality of pins 1010 and 1010b in an embodiment of an applicator device 4 according to the invention is shown. Here, the pins 1010 form a first longitudinal row while the pins 1010b form a second longitudinal row adjacent to the first. Here, the pins 1010 are oriented in the same direction, their plane P of symmetry being perpendicular to the longitudinal axis X, and the pins 1010b are oriented at 90 ° relative to the pins 1010, their plane P of symmetry passing through the longitudinal axis X. Other layouts are possible inspired by those already described previously in relation to other embodiments of the pins.
[0033] En figures 27 et 28, sont illustrées une variante 1110 du picot 1010 et une variante 1110b du picot 1010b. Ces variantes comprennent une deuxième extension secondaire respectivement 1011 et 1011 b symétrique de la première extension secondaire décrite précédemment. [0034] En figure 29, la variante de réalisation 1110c se différencie des deux précédentes, et en particulier du picot 1110, par le fait que l’extension principale 1111 n’est pas tronconique, mais est incurvée. In Figures 27 and 28 are illustrated a variant 1110 of the pin 1010 and a variant 1110b of the pin 1010b. These variants include a second secondary extension 1011 and 1011 b respectively symmetrical with the first secondary extension described above. In Figure 29, the alternative embodiment 1110c differs from the previous two, and in particular the pin 1110, in that the main extension 1111 is not frustoconical, but is curved.
[0035] En figure 30, le picot 1210 est une variante de réalisation des picots 1110 et 1110b où les extensions secondaires 1011 et 1011 b sont à 90° l’une de l’autre. En figure 31 , le picot 1310 est une variante de réalisation du picot 1210 où les extensions secondaires 1011 et 1011 b sont implantées sur le pont 1015 de manière décalée en hauteur : ainsi chacune des extensions secondaires 1011 , 1001 b s’étend en saillie d’un pont 1015 flexible indépendant associé. In Figure 30, the pin 1210 is an alternative embodiment of the pins 1110 and 1110b where the secondary extensions 1011 and 1011 b are at 90 ° from each other. In FIG. 31, the pin 1310 is an alternative embodiment of the pin 1210 where the secondary extensions 1011 and 1011 b are installed on the bridge 1015 in a staggered height: thus each of the secondary extensions 1011, 1001 b extends in projection d '' an associated independent flexible 1015 bridge.
[0036] La figure 33 illustre une version 1410, 1410b du picot comportant trois extensions secondaires 1011 , 1011 b. La figure 34, quant à elle, illustre une version 1510, 1510b du picot comportant quatre extensions secondaires 1011 , 1011 b. Les différentes extensions secondaires peuvent être uniformément ou non réparties autour de l’extension principale 11. Figure 33 illustrates a version 1410, 1410b of the pin having three secondary extensions 1011, 1011 b. Figure 34, for its part, illustrates a version 1510, 1510b of the pin having four secondary extensions 1011, 1011 b. The different secondary extensions can be uniformly or not distributed around the main extension 11.
[0037] En figure 32 est représentée une autre variante de réalisation du picot 1010. Le picot 1610 de cette variante comporte depuis l’extrémité d’ancrage 14 vers l’extrémité libre 12, l’étage proximal 1613, le pont 1615 et l’étage distal 1611 , 1617. L’étage distal comporte une extension principale 1611 et une extension secondaire 1617 s’étendant depuis le pont 1615 le long et à distance de l’extension principale 1611. De plus, le picot 1610 comporte une première face latérale 1612 s’étendant sur toute la hauteur du picot 1610, le long de l’étage proximal 1613, le pont 1615 et l’extension principal 1611 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 et 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 ample information. D’autre part, l’extension secondaire 1617 comporte une deuxième face latérale 1618 orientée dans un sens opposé à la première face 1612 et qui s’appuie sur un cercle D. In Figure 32 is shown another alternative embodiment of the pin 1010. The pin 1610 of this variant comprises from the anchoring end 14 towards the free end 12, the proximal stage 1613, the bridge 1615 and l distal stage 1611, 1617. The distal stage comprises a main extension 1611 and a secondary extension 1617 extending from the bridge 1615 along and at a distance from the main extension 1611. In addition, the pin 1610 has a first face lateral 1612 extending over the entire height of the pin 1610, along the proximal stage 1613, the bridge 1615 and the main extension 1611 and bearing on a circle C. The circle C is in a plane which is perpendicular at the longitudinal axis X, a point of intersection of the longitudinal axis X with the plane of the circle C and on the circle C. Such a configuration of the circle C supporting one face of the pin is described in detail in the document FR 2 937 514 which it is poss ible to refer for further information. On the other hand, the secondary extension 1617 has a second lateral face 1618 oriented in a direction opposite to the first face 1612 and which rests on a circle D.
[0038] Un dispositif applicateur 6 selon l’invention est illustré en figure 39 comportant une implantation d’une pluralité de picots 1110 et 1510. L’implantation comporte des rangées longitudinales de picots 1510, chacune de ces rangées étant entourée de part et d’autre de rangées adjacentes longitudinales comportant des picots 1110. An applicator device 6 according to the invention is illustrated in Figure 39 comprising an implantation of a plurality of pins 1110 and 1510. The implantation comprises longitudinal rows of pins 1510, each of these rows being surrounded on either side by adjacent longitudinal rows comprising pins 1110.
[0039] En figure 35, est illustrée une autre variante de réalisation d’un picot 1710 pour un dispositif applicateur selon l’invention. Le picot 1710 comporte, depuis l’extrémité d’ancrage 14, un étage proximal 1713, un pont 1715 et un étage distal 1711 ,1717 s’étendant jusqu’à l’extrémité libre 12. L’étage distal comporte une extension principale 1717 s’étendant au droit de l’étage proximal 1713 via le pont 1715. L’extension principale 1717 comporte une face plane interne 1717a située dans le plan P du picot 1710. L’étage distal comporte en outre une extension secondaire 1711 qui s’étend le long et à distance de l’extension principale 1717. L’extension secondaire 1711 comporte une face interne plane 1711 a qui est non concomitante au plan P et s’étend en regard et à distance de ce dernier. In Figure 35 is illustrated another alternative embodiment of a pin 1710 for an applicator device according to the invention. The pin 1710 comprises, from the anchoring end 14, a proximal stage 1713, a bridge 1715 and a distal stage 1711, 1717 extending to the free end 12. The distal stage comprises a main extension 1717 extending to the right of the proximal stage 1713 via the bridge 1715. The main extension 1717 has an internal flat face 1717a situated in the plane P of the spike 1710. The distal stage also comprises a secondary extension 1711 which s extends along and at a distance from the main extension 1717. The secondary extension 1711 has a flat internal face 1711 a which is not concomitant with the plane P and extends opposite and at a distance from the latter.
[0040] En figure 36, est illustrée une autre encore de variante de réalisation d’un picot 1810 pour un dispositif applicateur selon l’invention. Le picot 1810 comporte, depuis l’extrémité d’ancrage 14, un étage proximal 1813, un pont 1815 et un étage distal 1711 ,1717 s’étendant jusqu’à l’extrémité libre 12. L’étage distal comporte une extension principale à deux branches 1717, symétriques en miroir l’une par rapport à l’autre, s’étendant au droit de l’étage proximal 1813 via le pont 1815. Les branches 1717 comportent une face plane interne 1717a située dans le plan P du picot 1810. L’étage distal comporte en outre une extension secondaire 1711 qui s’étend le long et à distance de l’extension principale. L’extension secondaire 1711 comporte une face interne plane 1711 a qui est non concomitante au plan P et s’étend en regard et à distance de ce dernier. In Figure 36, another yet illustrated alternative embodiment of a pin 1810 for an applicator device according to the invention is illustrated. The pin 1810 comprises, from the anchoring end 14, a proximal stage 1813, a bridge 1815 and a distal stage 1711, 1717 extending to the free end 12. The distal stage comprises a main extension to two branches 1717, symmetrical in mirror relation to each other, extending to the right of the proximal stage 1813 via the bridge 1815. The branches 1717 have an internal planar face 1717a located in the plane P of the pin 1810 The distal stage further comprises a secondary extension 1711 which extends along and at a distance from the main extension. The secondary extension 1711 has a plane internal face 1711 a which is not concomitant with the plane P and extends opposite and at a distance from the latter.
[0041] Les extensions 1717 et/ou 1711 s’étendent verticalement sur les figures soit de manière rectiligne, soit de manière incurvée selon une seule courbe ou selon plusieurs courbes. The extensions 1717 and / or 1711 extend vertically in the figures either in a straight line or in a curved manner according to a single curve or according to several curves.
[0042] Jusque-là, nous avons décrit des dispositifs applicateurs selon l’invention dans une version principalement de brosse à mascara ou assimilés. D’autres formes sont nécessaires pour des applications dirigées vers l’épiderme (peau, lèvres). [0043] En référence aux figures 42 et 43, nous allons décrire un autre mode de réalisation d’un dispositif applicateur 2020 selon l’invention. Ce dispositif applicateur 2020 selon l’invention comporte une âme 2000 qui est creuse comportant un tube 2001 comportant une fente 2002 longitudinale. Une surface externe du tube 2001 comporte une implantation de picots 2010 qui peuvent avoir la structure de l’un des picots décrits précédemment. Une telle structure de l’âme 2000 permet de la rendre développable de sorte à devenir plane comme illustré à la figure 42b. Cela permet de mouler une telle âme comportant des picots complexes sous sa forme de tube sensiblement cylindrique permettant un démoulage desdits picots complexes, comme ceux décrits précédemment ou d’autres, ce qui est très difficilement faisable, voire impossible, directement sous une forme plane et/ou développée de ladite âme. So far, we have described applicator devices according to the invention in a version mainly of mascara brush or the like. Other forms are necessary for applications directed towards the epidermis (skin, lips). Referring to Figures 42 and 43, we will describe another embodiment of an applicator device 2020 according to the invention. This applicator device 2020 according to the invention comprises a core 2000 which is hollow comprising a tube 2001 comprising a longitudinal slot 2002. An external surface of the tube 2001 includes an implantation of pins 2010 which may have the structure of one of the pins described above. Such a structure of the core 2000 makes it possible to make it developable so as to become plane as illustrated in FIG. 42b. This makes it possible to mold such a core comprising complex spikes in the form of a substantially cylindrical tube allowing demolding of said complex spikes, like those described above or others, which is very difficult, if not impossible, directly in planar form and / or developed from said soul.
[0044] Le dispositif applicateur 2020 selon l’invention comporte en outre un support 2021 comportant un logement de réception 2023 bordé de part et d’autre de glissières 2022. L’âme 2000, une fois développée, est introduite dans le logement 2023 en la faisant coulisser le long des glissières 2022. In fine, le dispositif applicateur 2020 selon l’invention forme une spatule pour l’application d’un produit fluide ou pâteux sur un épiderme. The applicator device 2020 according to the invention further comprises a support 2021 comprising a receiving housing 2023 bordered on either side by slides 2022. The core 2000, once developed, is introduced into the housing 2023 in sliding it along the slides 2022. Ultimately, the applicator device 2020 according to the invention forms a spatula for applying a fluid or pasty product to an epidermis.
[0045] En référence à la figure 44 nous allons décrire un deuxième mode de réalisation d’une âme 3000 creuse développable. Dans cette variante de réalisation, l’âme 3000 comporte un tube 3001 comportant une fente longitudinale 3002. Une surface externe du tube 3001 comporte une implantation de picots 10 qui peuvent avoir la structure de l’un des picots décrits précédemment. Au niveau d’une extrémité, l’âme 3000 comporte une ogive 3003 de forme essentiellement tronconique. Au niveau de l’extrémité sur laquelle est placée l’ogive 3003, le tube 3001 comporte une découpe en biais 3004. Cette découpe va permettre au tube 3001 de pouvoir se développer sans être gêné par l’ogive 3003. D’autre part, l’âme 3000 comporte, ici illustrés, des orifices longitudinaux 3005 traversant une épaisseur du tube 3001 et situés entre les rangées longitudinales de picots 10. En variante de réalisation, l’âme 3000 ne comporta pas d’orifices longitudinaux. [0046] En référence à la figure 45, le dispositif applicateur 3020 selon l’invention comporte un support 3021 destiné à recevoir l’âme 3000 à coulissement. Le support comporte un corps 3023 en forme d’épée comportant deux réservoirs 3022 longitudinaux ouverts sur le dessus destiné à recevoir du produit liquide ou pâteux à appliquer. Le corps 3023 se termine par une garde 3024. Comme illustré à la figure 45, l’âme 3000 creuse développable est enfilée par coulissement sur le corps 3023 du support 3021 , la forme du corps 3023 étant agencée de sorte à développer progressivement le tube 3001 jusqu’à ce que l’âme 3000 vienne en contact d’appui contre la garde 3024, l’ogive 3003 recevant une pointe du corps du support 3021. Une fois en place, les orifices longitudinaux 3005 permettent au produit stocké dans les réservoirs 3022 de parvenir aux picots 10. Referring to Figure 44 we will describe a second embodiment of a developable hollow core 3000. In this alternative embodiment, the core 3000 comprises a tube 3001 comprising a longitudinal slot 3002. An external surface of the tube 3001 comprises an implantation of pins 10 which may have the structure of one of the pins described above. At one end, the core 3000 comprises an ogive 3003 of essentially frustoconical shape. At the end on which the warhead 3003 is placed, the tube 3001 has a bias cut 3004. This cut will allow the tube 3001 to be able to develop without being hindered by the warhead 3003. On the other hand, the core 3000 comprises, here illustrated, longitudinal orifices 3005 passing through a thickness of the tube 3001 and situated between the longitudinal rows of pins 10. In an alternative embodiment, the core 3000 did not comprise longitudinal orifices. Referring to Figure 45, the applicator device 3020 according to the invention comprises a support 3021 for receiving the sliding core 3000. The support comprises a body 3023 in the form of a sword comprising two longitudinal tanks 3022 open on the top intended to receive liquid or pasty product to be applied. The body 3023 ends in a guard 3024. As illustrated in FIG. 45, the hollow developable core 3000 is threaded by sliding on the body 3023 of the support 3021, the shape of the body 3023 being arranged so as to progressively develop the tube 3001 until the core 3000 comes into bearing contact against the guard 3024, the warhead 3003 receiving a point from the body of the support 3021. Once in place, the longitudinal orifices 3005 allow the product stored in the tanks 3022 to reach the pins 10.
[0047] La figure 46 illustre une première variante du support 3120 dans lequel le corps 3123 est plein et ne présente pas de réservoirs. Figure 46 illustrates a first variant of the support 3120 in which the body 3123 is full and has no reservoirs.
[0048] La figure 47 illustre une deuxième variante du support 3220 dans lequel le corps 3223 comporte un évidement 3222 qui fait office de réservoir à produit, une fois l’âme 3000 mise en place sur le support 3220. FIG. 47 illustrates a second variant of the support 3220 in which the body 3223 has a recess 3222 which acts as a product reservoir, once the core 3000 has been placed on the support 3220.
[0049] La figure 48 illustre une troisième variante du support 3320 dans lequel le corps 3323 comporte une série de bosses 3322 s’étendant en saillie d’une face supérieure qui est recouverte par l’âme 3000, une fois en place sur le support 3320, les espacements entre les bosses 3322 formant des réservoirs à produit. Il est à noter qu’au surplus, ces espacements laissent des « vides » entre la face supérieure du support 3320 et une surface interne de l’âme 3000. Ces « vides » permettent ainsi à l’âme 3000 de fléchir lors de l’application du produit cosmétique rendant encore plus doux et tactile le geste d’application (sensation de confort), les picots poussant alors l’âme 3000 qui « s’effondre » légèrement en face des espacements du support 3320. Figure 48 illustrates a third variant of the support 3320 in which the body 3323 has a series of bumps 3322 projecting from an upper face which is covered by the core 3000, once in place on the support 3320, the spacings between the bumps 3322 forming product reservoirs. It should be noted that, moreover, these spacings leave “voids” between the upper face of the support 3320 and an internal surface of the core 3000. These “voids” thus allow the core 3000 to bend during the application of the cosmetic product making the gesture of application even more soft and tactile (feeling of comfort), the pins then pushing the core 3000 which “collapses” slightly in front of the spacings of the support 3320.
[0050] En figure 49, est illustrée une variante de réalisation 3420 d’un des supports précédents dans lequel le corps 3423 comporte une implantation de picots 10 (qui peuvent avoir la structure de l’un des picots décrits précédemment) sur une face opposée à celle recouverte par l’âme 3000 un fois celle-ci en place. [0051] En figures 50 à 52, est illustrée une variante de réalisation 3520 d’un des supports précédents, en particulier le support 3021. Le support 3520 est semblable au support 3021 si ce n’est qu’il comporte en outre un conduit 3025 traversant, de manière coaxiale, une poignée 3026 de la garde 3024 de sorte à déboucher dans les deux réservoirs 3022 longitudinaux ouverts sur le dessus du corps 3023. Lors d’une utilisation illustrée à la figure 52, le produit cosmétique ou de soin P suit un cheminement illustré par les flèches FP en entrant par l’arrière de la poignée 3026 dans le conduit 3025 puis s’écoulant dans les réservoirs 3022 pour finir par sortir à travers les orifices longitudinaux 3005 de l’âme 3000 mise en place sur le support 3520. In Figure 49 is illustrated an alternative embodiment 3420 of one of the above supports in which the body 3423 has an implantation of pins 10 (which may have the structure of one of the pins described above) on an opposite face to that covered by the core 3000 once it is in place. In Figures 50 to 52 is illustrated an alternative embodiment 3520 of one of the preceding supports, in particular the support 3021. The support 3520 is similar to the support 3021 except that it further comprises a conduit 3025 passing, coaxially, a handle 3026 of the guard 3024 so as to open into the two longitudinal tanks 3022 open on the top of the body 3023. During a use illustrated in FIG. 52, the cosmetic or care product P follows a path illustrated by the arrows FP by entering from the rear of the handle 3026 in the conduit 3025 then flowing into the tanks 3022 and finally exiting through the longitudinal orifices 3005 of the core 3000 placed on the support 3520.
[0052] En référence aux figures 53 à 56, nous allons décrire une variante de réalisation 3620 d’un des supports précédents, en particulier, sans être limitatif, le support 3120. Le support 3620 est semblable au support 3120 si ce n’est qu’il comporte un conduit 3125 traversant longitudinalement le support 3620 depuis une extrémité de la poignée 3026 de la garde 3024 jusqu’à une extrémité 3126 du corps 3123. Lors d’une utilisation illustrée à la figure 55 ou à la figure 56, le produit cosmétique ou de soin P suit un cheminement illustré par les flèches FP en entrant par l’arrière de la poignée 3026 dans le conduit 3125 puis s’écoulant le long du conduit 3125 jusqu’à ressortir par l’extrémité 3126, à la manière d’une mine de portemine. Referring to Figures 53 to 56, we will describe an alternative embodiment 3620 of one of the previous supports, in particular, without being limiting, the support 3120. The support 3620 is similar to the support 3120 except that it comprises a conduit 3125 passing longitudinally through the support 3620 from one end of the handle 3026 of the guard 3024 to one end 3126 of the body 3123. During a use illustrated in FIG. 55 or in FIG. 56, the cosmetic or care product P follows a path illustrated by the arrows FP by entering from the rear of the handle 3026 in the conduit 3125 then flowing along the conduit 3125 until emerging through the end 3126, in the manner of a mechanical pencil mine.
[0053] Le support 3620 est monté, ici, avec une âme creuse 3009 qui est une variante de réalisation de l’âme creuse 3000 précédemment décrit adaptée pour le support 3620 de sorte à laisser libre l’extrémité 3126 de sortie du conduit 3125. D’autre part, le support 3620 comporte une face 3624, généralement opposée à une face du support 3620 sur laquelle est montée l’âme creuse 3009, qui a une structure particulière : un flocage, ou une couche supplémentaire d’une matière plus tendre, de type éponge par exemple, possédant des alvéoles, ou une micro- structuration de ladite face 3624, ou encore de toute couche de matière tendre et micro-structurée ayant le même effet qu’une zone à une extrémité des doigts dont un utilisateur se sert naturellement. [0054] Dans des variantes de réalisation d’un dispositif applicateur selon l’invention, illustrées aux figures 57 et 58, ce dernier comporte un manche 3700 monté sur la poignée 3026 du support 3620 et comporte des moyens de mise en œuvre 3701 , 3710 du cheminement, illustré par la flèche FP, du produit P. Le moyen de mise en œuvre 3701 est un poussoir 3701 sur lequel une action 3702 de poussée provoque un cheminement du produit P. D’autre part, le moyen de mise en œuvre 3710 est un bague 3710 montée à rotation et agencée de sorte qu’une rotation 3712 de la bague 3710 provoque un cheminement du produit P. Le poussoir 3701 ou la bague 3710 agissent, pour cela, sur un système doseur de produit P agencé au sein du manche 3700. Ce système doseur est une pompe ou un dispositif de type portemine selon la consistance du produit P utilisé. The support 3620 is mounted, here, with a hollow core 3009 which is an alternative embodiment of the hollow core 3000 previously described adapted for the support 3620 so as to leave free the end 3126 of the outlet of the conduit 3125. On the other hand, the support 3620 has a face 3624, generally opposite a face of the support 3620 on which is mounted the hollow core 3009, which has a particular structure: flocking, or an additional layer of a softer material. , of the sponge type for example, having cells, or a micro-structuring of said face 3624, or of any layer of soft and micro-structured material having the same effect as an area at one end of the fingers of which a user is serves naturally. In alternative embodiments of an applicator device according to the invention, illustrated in Figures 57 and 58, the latter comprises a handle 3700 mounted on the handle 3026 of the support 3620 and includes means of implementation 3701, 3710 of the path, illustrated by the arrow FP, of the product P. The means of implementation 3701 is a pusher 3701 on which a pushing action 3702 causes a path of the product P. On the other hand, the means of implementation 3710 is a ring 3710 rotatably mounted and arranged so that a rotation 3712 of the ring 3710 causes a flow of the product P. The pusher 3701 or the ring 3710 act, for this, on a product metering system P arranged within the 3700 handle. This dosing system is a mechanical pump or device depending on the consistency of the product P used.
[0055] Il ressort de ce qui précède qu’une telle structure du picot, telle que décrite précédemment, pour un dispositif applicateur selon l’invention permet de conserver un étage distal suffisamment rigide pour permettre de démêler les fibres kératiniques tout en les guidant, la liaison flexible formée par l’étage proximal et/ou le pont servant d’amortisseur permettant de gommer la sensation de piqûre lorsque l’extrémité libre du picot vient en contact avec la peau sous-jacente. D’autre part, la déformation ainsi obtenue en utilisation au niveau de la base du picot permet au produit présent à cet endroit de remonter vers l’extrémité libre du picot. It appears from the above that such a structure of the spike, as described above, for an applicator device according to the invention makes it possible to keep a distal stage sufficiently rigid to allow to disentangle the keratin fibers while guiding them, the flexible connection formed by the proximal stage and / or the bridge serving as a shock absorber making it possible to erase the feeling of pricking when the free end of the pin comes into contact with the underlying skin. On the other hand, the deformation thus obtained in use at the level of the base of the pin allows the product present at this location to go up towards the free end of the pin.
[0056] In fine, le dispositif applicateur selon l’invention permet d’améliorer la charge de produit cosmétique ou de soins et son application sur des fibres kératiniques (tout en assurant une séparation optimale de ces dernières) ou l’épiderme tout en procurant une sensation de confort optimal à son utilisateur. Ultimately, the applicator device according to the invention makes it possible to improve the charge of cosmetic or care product and its application to keratin fibers (while ensuring optimal separation of the latter) or the epidermis while providing a feeling of optimal comfort for its user.
[0057] Bien entendu, il est possible d’apporter à l’invention de nombreuses modifications sans pour autant sortir du cadre de celle-ci. Of course, it is possible to make numerous modifications to the invention without going beyond the ambit of the latter.
