Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention se rapporte au domaine des applicateurs de produit cosmétique fluide ou pâteux, de type mascara. L'invention concerne plus spécifiquement le dispositif ou moyen applicateur du produit cosmétique.The invention relates to the field of applicators for fluid or pasty cosmetic products, such as mascara. The invention relates more specifically to the device or means for applicating the cosmetic product.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF PRIOR ART

On connait déjà dans l'art antérieur de très nombreux applicateurs de mascara. Le dispositif d'application en lui-même peut être par exemple une brosse de forme allongée, dotée d'une âme centrale à partir de laquelle sont hérissés un ensemble de poils ou picots. Les poils relèvent d'une technologie ancienne : un fil métallique torsadé retient des poils qui sont hérissés transversalement. Un exemple d'application est illustré dans le brevet américain US 5 611 361 .Many mascara applicators are already known in the prior art. The application device itself may be, for example, an elongated brush with a central core from which a set of bristles or spikes protrude. The bristles are based on old technology: a twisted metal wire holds the bristles, which are protruded transversely. An example of an application is illustrated in the US patent US 5,611,361 .

Plus récemment, le dispositif d'application se présente sous la forme d'une brosse comprenant une série de picots encastrés sur l'âme longitudinale de la brosse. L'ensemble est moulé en matière plastique. Un dispositif d'application forme ainsi avec un réservoir approprié dans lequel il est insérable, un distributeur de produit cosmétique. Les demandes FR 2 810 860 et WO 2011/045770 montrent quelques exemples d'applicateurs issus de ce concept. Un exemple d'applicateur selon la préambule de la revendication est connu d'après EP1767119A1 .More recently, the application device is in the form of a brush comprising a series of spikes embedded on the longitudinal core of the brush. The assembly is molded from plastic. An application device thus forms, with a suitable reservoir into which it can be inserted, a cosmetic product dispenser. Applications FR 2 810 860 And WO 2011/045770 show some examples of applicators based on this concept. An example of an applicator according to the preamble of the claim is known from EP1767119A1 .

Les inconvénients des dispositifs d'application, ou brosses, de l'art antérieur sont que les picots ne permettent pas de réaliser correctement le transfert du produit cosmétique du réservoir sur les picots, et une application appropriée du produit sur les fibres kératiniques, pour les allonger, les épaissir et/ou les séparer.The disadvantages of the application devices, or brushes, of the prior art are that the spikes do not allow the cosmetic product to be correctly transferred from the reservoir to the spikes, and the product to be properly applied to the keratin fibres, to lengthen, thicken and/or separate them.

Une solution envisagée par l'art antérieur pour améliorer la charge en mascara des brosses consiste à utiliser des picots ayant une face plane pour recueillir le mascara tandis que la face non plane participe à la séparation des cils. Le document EP 1 872 682 décrit une telle brosse ; les picots sont disposés selon des rangées parallèles à l'axe longitudinal de la brosse et tous les picots d'une rangée présentent leur face plane du même côté : les faces planes sont alignées tandis que les faces non planes se trouvent du même côté de la ligne. L'utilisateur de la brosse imprime donc un mouvement de la brosse dans une direction perpendiculaire à l'axe longitudinal de la brosse, tout en faisant tourner celle-ci.One solution envisaged by the prior art to improve the mascara loading of brushes consists of using pins having a flat face to collect the mascara while the non-flat face participates in the separation of the eyelashes. The document EP 1 872 682 describes such a brush; the pins are arranged in rows parallel to the longitudinal axis of the brush and all the pins in a row have their flat faces on the same side: the flat faces are aligned while the non-flat faces are on the same side of the line. The user of the brush therefore prints a movement of the brush in a direction perpendicular to the longitudinal axis of the brush, while rotating the brush.

Les brosses de ce type ne présentent pas une efficacité maximale car les faces planes ne participent pas à la séparation des cils et les faces non planes ne participent pas à la charge en mascara. Avec ce type de brosse, l'utilisatrice est donc contrainte d'effectuer plusieurs passages sur ses cils tout en inversant le mouvement de la brosse pour s'assurer de récupérer une charge suffisante en mascara.Brushes of this type are not as effective as they used to be because the flat sides do not help separate the lashes and the non-flat sides do not help with mascara loading. With this type of brush, the user is therefore forced to make several strokes over their lashes while reversing the movement of the brush to ensure they collect enough mascara.

De façon quelque peu différente, la demande de brevet EP 1611 817 divulgue un dispositif d'application de mascara comprenant un support longitudinal, une première et une deuxième rangées de picots réalisés de manière monolithique avec le support, encastrés d'un même côté du support et s'étendant sur plus d'un quart de la longueur du support. Les dents (ou picots) s'étendent de part et d'autre d'une surface géométrique dite de séparation formée selon deux directions et surfaces non parallèles. Les picots sont érigés à partir d'une face plane du support, et ils sont ménagés en quinconce de part et d'autre de la surface de séparation. Ainsi lors de l'application du mascara, le mouvement de va et vient imprimer à la brosse ne permet pas une répartition optimale de la charge ni une séparation appropriée des cils.Somewhat differently, the patent application EP 1611 817 discloses a mascara application device comprising a longitudinal support, a first and a second row of spikes made monolithically with the support, embedded on the same side of the support and extending over more than a quarter of the length of the support. The teeth (or spikes) extend on either side of a geometric surface called a separation surface formed in two non-parallel directions and surfaces. The spikes are erected from a flat face of the support, and they are arranged in a staggered pattern on either side of the separation surface. Thus, when applying mascara, the back and forth movement given to the brush does not allow for optimal distribution of the load or appropriate separation of the eyelashes.

On connait encore la demande de brevet FR 2 930 875 qui décrit un dispositif applicateur de produit cosmétique comprenant une âme longitudinale supportant plusieurs rangées de picots présentant une face plane et projetés radialement depuis l'âme. Les picots sont répartis selon au moins une rangée parallèle à l'axe longitudinal de l'âme, de telle sorte que sur une même rangée les picots sont positionnés alternativement de part et d'autre d'une ligne (ou plan) centrale de la rangée, avec leur face plane tournée vers l'intérieur de la rangée. Selon une caractéristique de l'invention, les faces planes des picots d'une même rangée s'étendent perpendiculairement à l'âme et sont alignées, et elles sont orientées dans les deux sens giratoires autour de l'âme.The patent application is still known FR 2 930 875 which describes a cosmetic product applicator device comprising a longitudinal core supporting several rows of spikes having a flat face and projecting radially from the core. The spikes are distributed in at least one row parallel to the longitudinal axis of the core, such that in the same row the spikes are positioned alternately on either side of a central line (or plane) of the row, with their flat face facing the inside of the row. According to a characteristic of the invention, the flat faces of the spikes in the same row extend perpendicular to the core and are aligned, and they are oriented in both rotating directions around the core.

Même si cette solution apporte une certaine amélioration vis-à-vis de l'art antérieur, la modularité de la charge n'est pas obtenue favorablement. En outre la séparation des cils reste perfectible. Although this solution provides some improvement over the prior art, the modularity of the load is not achieved favorably. In addition, the separation of the eyelashes remains improvable.

Un développement apparait donc nécessaire notamment au niveau de la forme de chaque picot. Chaque picot doit contribuer à améliorer, seul ou en combinaison avec d'autres picots, à la fois la charge en produit, et la séparation des cils ou fibres kératiniques.Development therefore appears necessary, particularly in terms of the shape of each spike. Each spike must contribute to improving, alone or in combination with other spikes, both the product load and the separation of the eyelashes or keratin fibers.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention vise à remédier aux inconvénients de l'état de la technique notamment en ce qui concerne la charge en produit cosmétique et la séparation des cils.The invention aims to remedy the drawbacks of the state of the art, particularly with regard to the loading of cosmetic product and the separation of eyelashes.

Pour ce faire est proposé selon l'invention un dispositif applicateur d'un produit de type fluide ou pâteux sur des fibres kératiniques, comprenant une âme centrale de forme allongée qui s'étend selon un axe longitudinal XX, au moins une rangée de picots allongés comprenant une première extrémité encastrée sur l'âme et une deuxième extrémité libre, les picots et l'âme étant formés en une seule pièce. Selon l'invention, l'un au moins des picots est délimité par une première face plane confondue avec un plan longitudinal du dispositif, dit plan de référence P, qui s'étend radialement vis-à-vis de l'âme, et par une deuxième face plane formant avec ladite première face plane un angle d'environ 180° ; en outre ledit au moins un picot comprend une première zone encastrée sur l'âme et de section transversale sensiblement constante, la deuxième zone comprenant au moins une première portion juxtaposée et dans le prolongement de la première zone, et une deuxième portion juxtaposée à recouvrement avec la première portion selon ledit plan de référence P.To do this, the invention proposes a device for applying a fluid or pasty type product to keratin fibers, comprising a central core of elongated shape which extends along a longitudinal axis XX, at least one row of elongated spikes comprising a first end embedded on the core and a second free end, the spikes and the core being formed in a single piece. According to the invention, at least one of the spikes is delimited by a first flat face coinciding with a longitudinal plane of the device, called the reference plane P, which extends radially with respect to the core, and by a second flat face forming with said first flat face an angle of approximately 180°; furthermore, said at least one spike comprises a first zone embedded on the core and of substantially constant cross-section, the second zone comprising at least a first juxtaposed portion and in the extension of the first zone, and a second juxtaposed portion overlapping with the first portion along said reference plane P.

Ces caractéristiques qui constituent une définition technique précise de la forme et de la disposition individuelle et/ou réciproque des picots, améliorent les fonctions énoncées ci-avant.These characteristics, which constitute a precise technical definition of the shape and individual and/or reciprocal arrangement of the pins, improve the functions stated above.

De façon avantageuse, non conforme à l'invention, la forme et/ou la disposition de deux picots successivement implantés selon l'axe XX, est apte à créer au moins une ouverture distale entre eux. Ladite ouverture distale peut être ouverte vers l'extrémité libre du picot, en forme générale de diapason.Advantageously, not in accordance with the invention, the shape and/or arrangement of two pins successively implanted along the axis XX, is capable of creating at least one distal opening between them. Said distal opening can be open towards the free end of the pin, in the general shape of a tuning fork.

Non conforme à l'invention, la forme et/ou la disposition de deux picots successivement implantés selon l'axe XX, est apte à créer une deuxième ouverture entre eux. Selon l'option envisagée, l'ouverture distale et la deuxième ouvertures peuvent être distinctes ou communicantes.Not in accordance with the invention, the shape and/or arrangement of two pins successively implanted along the XX axis, is capable of creating a second opening between them. Depending on the option considered, the distal opening and the second opening can be separate or communicating.

En outre, selon un mode de réalisation de l'invention, deux au moins des picots constitutifs d'une rangée présentent une orientation identique.Furthermore, according to one embodiment of the invention, at least two of the pins constituting a row have an identical orientation.

Conformément à un autre mode de réalisation de l'invention, deux au moins des picots constitutifs d'une rangée présentent une orientation différente.According to another embodiment of the invention, at least two of the pins constituting a row have a different orientation.

Par ailleurs, la distance mesurée selon l'axe XX entre deux picots successifs peut être négative, nulle ou bien positive, inférieure à environ 2 mm. Cette distance est adaptée facilement au cas particulier envisagé.Furthermore, the distance measured along the XX axis between two successive pins can be negative, zero or positive, less than approximately 2 mm. This distance is easily adapted to the particular case considered.

Selon l'invention, la première et la deuxième faces forment entre elles un angle d'environ 180°, et la deuxième zone comprend au moins une première portion juxtaposée et dans le prolongement de la première zone, et une deuxième portion juxtaposée à recouvrement avec la première portion selon ledit plan de référence P.According to the invention, the first and second faces form an angle of approximately 180° between them, and the second zone comprises at least a first portion juxtaposed and in the extension of the first zone, and a second portion juxtaposed and overlapping with the first portion according to said reference plane P.

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

La figure 1 montre le principe de l'invention qui concerne donc un dispositif d'application d'un produit de type fluide ou pâteux sur des fibres kératiniques tels que des cils. De façon connue, ce dispositif comprend une âme 1 allongée qui s'étend selon un axe longitudinal XX ; la section transversale de l'âme peut être constante ou non. Au moins une rangée de picots ou protubérances 2, de forme générale allongée, comprennent une première extrémité 20 encastrée sur l'âme 1 et une deuxième extrémité 21 libre ; les picots 2 et l'âme sont avantageusement formés en une seule pièce notamment en plastique venu de moule. Le dispositif d'application est de forme générale allongée et son volume extérieur peut prendre différentes formes : cylindrique, en tronc de cône, en cacahouète ou autre ; l'homme de métier la choisit en fonction du cas de figure précis. Les figures 1A et 1B montrent un volume extérieur sensiblement cylindrique ; la figure 2A une forme extérieure en cacahouète ; la figure 3A une forme ondulée.There Figure 1 shows the principle of the invention which therefore relates to a device for applying a fluid or pasty type product to keratin fibers such as eyelashes. In a known manner, this device comprises an elongated core 1 which extends along a longitudinal axis XX; the cross-section of the core may or may not be constant. At least one row of pins or protuberances 2, of generally elongated shape, comprise a first end 20 embedded on the core 1 and a second free end 21; the pins 2 and the core are advantageously formed in a single piece, in particular from plastic from a mold. The application device is of generally elongated shape and its external volume may take different forms: cylindrical, truncated cone, peanut-shaped or other; the professional chooses it according to the specific case. Figures 1A and 1B show a substantially cylindrical exterior volume; the Figure 2A a peanut-shaped exterior; Figure 3A a wavy shape.

Selon l'invention et comme illustré par exemple sur les figures 4 à 13, l'un au moins des picots est délimité par une première face plane 200 confondue ou sensiblement confondue avec un plan P dit longitudinal ou de référence qui s'étend radialement vis-à-vis de l'âme 1. La figure 1 montre clairement le plan P ; cette figure illustre en outre une rangée de picots 2 qui présentent une face confondue avec le plan P.According to the invention and as illustrated for example in the figures 4 to 13 , at least one of the pins is delimited by a first flat face 200 merged or substantially merged with a plane P called longitudinal or reference which extends radially with respect to the core 1. The Figure 1 clearly shows plane P; this figure also illustrates a row of pins 2 which have a face merged with plane P.

Les (ou au moins l'un des) picots 2 sont en outre définis et délimités par une deuxième face plane 210 formant avec la première face plane 200 un angle compris entre environ 10° et 180°. Les différentes figures qui suivent montrent les angles envisageables, qui sont choisis, déterminés, calculés par l'homme de métier.The (or at least one of the) pins 2 are further defined and delimited by a second flat face 210 forming with the first flat face 200 an angle of between approximately 10° and 180°. The various figures which follow show the possible angles, which are chosen, determined, calculated by the person skilled in the art.

En outre au moins un picot 2 comprend une première zone 22 encastrée sur l'âme 1 ; cette zone correspond à l'encastrement 21 et elle présente une section transversale sensiblement constante, de préférence en forme de portion de cercle ; c'est le « pied » ou l'ancrage de chaque picot sur l'âme 1. Dans le prolongement longitudinal de la première zone 22, on considère une deuxième zone 23 qui peut présenter diverses formes, comme l'illustrent notamment mais non exhaustivement les figures annexées.Furthermore, at least one spike 2 comprises a first zone 22 embedded on the core 1; this zone corresponds to the embedding 21 and it has a substantially constant cross-section, preferably in the form of a portion of a circle; this is the “foot” or the anchoring of each spike on the core 1. In the longitudinal extension of the first zone 22, a second zone 23 is considered which can have various shapes, as illustrated in particular but not exhaustively in the appended figures.

Selon les figures 4A, 4B, 4C la première 200 et la deuxième 210 faces du picot considéré forment un angle droit entre elles, comme le montre clairement la figure 4C. La deuxième zone 23 présente ici une première portion renflée - ou premier renflement- 231 juxtaposée et dans le prolongement de la première zone 22, et une deuxième portion renflée - ou deuxième renflement- 232 dans le prolongement du premier renflement 231.According to the Figures 4A, 4B, 4C the first 200 and the second 210 faces of the pin considered form a right angle between them, as clearly shown in Figure 4C The second zone 23 here has a first swollen portion - or first bulge - 231 juxtaposed and in the extension of the first zone 22, and a second swollen portion - or second bulge - 232 in the extension of the first bulge 231.

Les figures 5A et 5B concernent un mode de réalisation qui diffère de celui des figures 4 en ce que la deuxième portion renflée 232 présente un évidement 233 au niveau de la partie distale 21 du picot. La figure 5B diffère en outre par l'angle entre les deux faces 200, 210 du picot : cet angle est ici d'environ 45°. Ce picot est donc plus fin et, toutes choses égales par ailleurs, plus souple que celui illustré par les figures 4.THE Figures 5A and 5B relate to an embodiment which differs from that of the figures 4 in that the second swollen portion 232 has a recess 233 at the level of the distal part 21 of the spike. Figure 5B further differs by the angle between the two faces 200, 210 of the pin: this angle is here approximately 45°. This pin is therefore thinner and, all other things being equal, more flexible than that illustrated by the figures 4 .

Les figures 6A, 6B et 6C illustrent l'arrangement réciproque de deux picots adjacents, ainsi que leur forme intrinsèque. A la différence du picot des figures 5A, 5B et 5C, la forme de chaque picot comprend deux évidements 233 et 234, sensiblement dans le prolongement l'un de l'autre. Ces évidements sont aptes à former deux ouvertures 235, 236 dans le prolongement l'une de l'autre, avec une disposition réciproque appropriée de deux picots successifs.THE Figures 6A, 6B and 6C illustrate the reciprocal arrangement of two adjacent pins, as well as their intrinsic shape. Unlike the pin of the Figures 5A, 5B and 5C , the shape of each spike comprises two recesses 233 and 234, substantially in the extension of one another. These recesses are capable of forming two openings 235, 236 in the extension of one another, with an appropriate reciprocal arrangement of two successive spikes.

Les faces 200 et 210 sont ici orientées à 90° l'une de l'autre, bien que cette orientation puisse être différente sans sortir du cadre de l'invention. Les deux picots 2 présentent une orientation différente, à 180°.The faces 200 and 210 are here oriented at 90° to each other, although this orientation may be different without departing from the scope of the invention. The two pins 2 have a different orientation, at 180°.

Les figures 7A, 7B, 7C montrent une forme de la deuxième zone 23 proche de celle des figures 6, mais avec une section transversale sensiblement constante. Cette forme permet par une disposition choisie et appropriée, de former entre deux picots longitudinalement juxtaposés, une grande ouverture 230 allongée et fermée à l'extrémité distale 21.THE Figures 7A, 7B, 7C show a shape of the second zone 23 close to that of the figures 6 , but with a substantially constant cross-section. This shape allows, by a chosen and appropriate arrangement, to form between two longitudinally juxtaposed pins, a large opening 230 elongated and closed at the distal end 21.

Une variante du mode de réalisation des figures 7A, 7B, 7C est représentée sur les figures 8A, 8B et 8C. La différence réside dans l'ouverture 230 qui n'est pas fermée à l'extrémité distale 21. Une sorte de diapason constitue ici la deuxième zone 23 qui bénéficie d'une souplesse intéressante à la fois pour servir de réservoir de produit et pour retenir et guider les fibres kératiniques.A variant of the embodiment of the Figures 7A, 7B, 7C is represented on the Figures 8A, 8B and 8C The difference lies in the opening 230 which is not closed at the distal end 21. A sort of tuning fork here constitutes the second zone 23 which benefits from an interesting flexibility both to serve as a product reservoir and to retain and guide the keratin fibers.

Les figures 9A, 9B et 9C concernent des picots 2 du type présenté ci-dessus auxquels est ajouté un ergot ou excroissance 24 issu d'un renflement et/ou d'une convexité 232. Là encore, cette géométrie est intéressante pour améliorer le guidage des fibres kératiniques. Par ailleurs on cherche ici avantageusement à former une ouverture 236, à l'extrémité distale de deux picots juxtaposés.THE Figures 9A, 9B and 9C relate to spikes 2 of the type presented above to which is added a lug or outgrowth 24 originating from a bulge and/or a convexity 232. Here again, this geometry is of interest for improving the guidance of the keratin fibers. Furthermore, it is advantageous here to form an opening 236, at the distal end of two juxtaposed spikes.

Les figures 10A et 10B illustrent un picot 2 qui peut être réalisé de deux façons : soit par la juxtaposition à contact de deux picots dont la première 200 et la deuxième 210 faces font entre elles un angle de 90° ; soit par un seul picot dont les première et deuxième faces forment un angle de 180°. Dans les deux options, deux renflements 231, 232 sont prévus au niveau de la deuxième zone 23, et ces deux renflements sont issus de la ou des zones planes 200, 210. Les renflements sont orientés à 180° l'un de l'autre ; ils présentent une surface de contact confondue avec un plan de référence P.THE Figures 10A and 10B illustrate a spike 2 which can be made in two ways: either by the juxtaposition in contact of two spikes whose first 200 and second 210 faces form an angle of 90° between them; or by a single spike whose first and second faces form an angle of 180°. In both options, two bulges 231, 232 are provided at the level of the second zone 23, and these two bulges come from the flat zone(s) 200, 210. The bulges are oriented at 180° to each other; they have a contact surface merged with a reference plane P.

Les figures 11, 11A et 11B montrent un mode de réalisation selon lequel les picots 2 sont délimités par une première face plane 200 et une deuxième face plane 210 formant entre elles un angle d'environ 45°. Les deuxièmes zones 23 des picots sont formées par une succession de courbures concaves et convexes. La disposition de deux picots adjacents est telle qu'un écart E d'environ 0.01 mm peut être mesuré selon l'axe longitudinal XX du dispositif applicateur. L'orientation de deux picots adjacents n'est pas la même puisque les deuxièmes faces planes 210 se trouvent alternativement de part et d'autre du plan longitudinal P de référence, tandis que les premières faces 200 appartiennent au plan de référence P. Cette disposition permet de former dans l'espace deux ouvertures sensiblement distinctes 235, 236.THE Figures 11, 11A and 11B show an embodiment according to which the pins 2 are delimited by a first flat face 200 and a second flat face 210 forming between them an angle of approximately 45°. The second zones 23 of the pins are formed by a succession of concave and convex curvatures. The arrangement of two adjacent pins is such that a difference E of approximately 0.01 mm can be measured along the longitudinal axis XX of the applicator device. The orientation of two adjacent pins is not the same since the second flat faces 210 are located alternately on either side of the longitudinal reference plane P, while the first faces 200 belong to the reference plane P. This arrangement makes it possible to form two substantially distinct openings 235, 236 in space.

Les figures 12, 12A, 12B présentent un mode de réalisation qui diffère de celui des figures 11, 11A et 11B par l'écart E longitudinal d'implantation entre deux picots. Cet écart est environ dix fois plus grand, de sorte que les ouvertures 235, 236 ne sont pas fermées. L'homme de métier choisit la version la plus appropriée.THE figures 12, 12A, 12B present an embodiment which differs from that of the Figures 11, 11A and 11B by the longitudinal implantation gap E between two pins. This gap is approximately ten times larger, so that the openings 235, 236 are not closed. The person skilled in the art chooses the most appropriate version.

Les figures 13A, 13B et 13C montrent trois écarts possibles entre deux picots 2 longitudinalement adjacents. Selon la figure 13A, deux picots adjacents présentent une surface maximale de recouvrement au niveau de leurs premières faces planes 200 ; selon la figure 13B, la surface de recouvrement est d'environ la moitié des premières surfaces planes 200 ; selon la figure 13C, seule une faible portion de la surface de contact est prévue.THE Figures 13A, 13B and 13C show three possible gaps between two longitudinally adjacent pins 2. According to the Figure 13A , two adjacent pins have a maximum overlapping surface at the level of their first flat faces 200; according to the Figure 13B , the overlapping surface is approximately half of the first 200 planar surfaces; according to the Figure 13C , only a small portion of the contact surface is provided.

La figure 14 illustre par une perspective un mode préféré de réalisation.There Figure 14 illustrates by a perspective a preferred embodiment.

Un aspect intéressant de ce mode de réalisation concerne les ouvertures distales 236 formées par deux picots 2 successifs, sur plusieurs rangées de picots. Ces ouvertures 236 servent de réservoir pour le produit fluide ou pâteux. De tels réservoirs se remplissent facilement de produit dans la mesure où ils sont disposés en périphérie du volume occupé par le dispositif d'application ; les ouvertures étant par ailleurs formées par deux extrémités libres de picots, elles sont particulièrement flexibles, ce qui est intéressant pour les passages répétés des dispositifs applicateurs à travers les essoreurs - petits disques placés au niveau du col du conteneur-.An interesting aspect of this embodiment concerns the distal openings 236 formed by two successive spikes 2, on several rows of spikes. These openings 236 serve as a reservoir for the fluid or pasty product. Such reservoirs are easily filled with product since they are arranged on the periphery of the volume occupied by the application device; the openings being moreover formed by two free ends of spikes, they are particularly flexible, which is interesting for repeated passages of the applicator devices through the wringers - small discs placed at the neck of the container.

Les figures 15, 15A et 15B concernent une solution où la deuxième portion de la deuxième zone 23 du picot présente une forme en U dont le sommet est juxtaposé avec la première zone 22 au niveau d'un plan longitudinal P. La figure 15A montre clairement cet arrangement. Selon les figures 15 et 15A, plusieurs rangées de picots (six) tels que décrits ci-dessus sont prévues, radialement espacées sur l'âme. D'autres types de picots 2 peuvent être prévus sur une âme 1, par exemple radialement intercalés entre les picots en U. La figure 15B montre plus en détail un picot 2 tel que décrit ci-dessus.THE Figures 15, 15A and 15B relate to a solution where the second portion of the second zone 23 of the spike has a U shape whose apex is juxtaposed with the first zone 22 at the level of a longitudinal plane P. The Figure 15A clearly shows this arrangement. According to the Figures 15 and 15A , several rows of pins (six) as described above are provided, radially spaced on the core. Other types of pins 2 may be provided on a core 1, for example radially interposed between the U-shaped pins. The Figure 15B shows in more detail a pin 2 as described above.

Une variante de réalisation de l'invention est illustrée sur les figures 16, 16A et 16B. Selon ces figures, le picot comprend une première zone 22 encastrée sur l'âme, telle que déjà définie ; le picot comprend en outre une deuxième zone 23 ici définie par une première partie 231 dont les deux faces forment un angle de 180° et appartiennent au plan de référence P. La partie 231 se situe dans le prolongement longitudinal de la première zone 22 et elle est juxtaposée à recouvrement dans le plan P avec une deuxième partie 232, partie distale, qui se projette de l'autre côté du plan P, comme le montre notamment la figure 16B. La partie 232 présente une ouverture ou boucle fermée à son extrémité distale (non référencée mais correspondant à l'ouverture 236 des autres modes de réalisation des picots). Autrement dit le picot est ici « réparti » de part et d'autre du plan P. Il présente toutes les caractéristiques et avantages des autres modes de réalisation de l'invention.An alternative embodiment of the invention is illustrated in the Figures 16, 16A and 16B . According to these figures, the spike comprises a first zone 22 embedded on the core, as already defined; the spike further comprises a second zone 23 here defined by a first part 231 whose two faces form an angle of 180° and belong to the reference plane P. The part 231 is located in the longitudinal extension of the first zone 22 and it is juxtaposed with overlap in the plane P with a second part 232, distal part, which projects on the other side of the plane P, as shown in particular by Figure 16B . The part 232 has an opening or closed loop at its distal end (not referenced but corresponding to the opening 236 of the other embodiments of the spikes). In other words, the spike is here “distributed” on either side of the plane P. It has all the characteristics and advantages of the other embodiments of the invention.

Les figures 17, 17A et 17B concernent un mode de réalisation proche de celui illustré par les figures 16. La différence essentielle réside dans la forme de la deuxième partie 232, qui correspond ici à un crochet ouvert distalement. Ce mode de réalisation, plus souple que celui des figures 16, 16A, 16B, sera donc choisi par l'homme de métier lorsqu'une souplesse plus grande est requise. L'ouverture distale 236 est ici ouverte puisque définie par le crochet 232.THE Figures 17, 17A and 17B relate to an embodiment close to that illustrated by the figures 16 The essential difference lies in the shape of the second part 232, which here corresponds to a distally open hook. This embodiment, more flexible than that of the figures 16, 16A, 16B , will therefore be chosen by the person skilled in the art when greater flexibility is required. The distal opening 236 is open here since it is defined by the hook 232.

Sans sortir du cadre de l'invention, les variantes des figures 16 et 17 pourraient être réalisées par deux picots dont les faces planes 200, 210 font entre elles un angle de 90°, et dont les faces 210 n'appartenant pas au plan de référence P, sont accolées.Without departing from the scope of the invention, the variants of the figures 16 and 17 could be made by two pins whose flat faces 200, 210 form an angle of 90° between them, and whose faces 210 not belonging to the reference plane P, are joined.

Par ailleurs, le nombre de rangées de picots varie préférentiellement de un à vingt-quatre, avec des picots et des arrangements de picots identiques ou non. En particulier, comme montré sur la figure 2B, les picots peuvent être tous orientés de la même façon sur une même rangée ou sur l'ensemble des picots constitutifs du dispositif d'application ; les picots peuvent aussi présenter des orientations différentes, par exemple alternées de part et d'autre du plan longitudinal P.Furthermore, the number of rows of pins preferably varies from one to twenty-four, with pins and pin arrangements identical or not. In particular, as shown in the Figure 2B , the spikes can all be oriented in the same way on the same row or on all the spikes constituting the application device; the spikes can also have different orientations, for example alternating on either side of the longitudinal plane P.

D'autres modifications non essentielles peuvent être prévues soit sur la forme intrinsèque des picots, soit sur leur orientation et/ou disposition réciproque, sans sortir du cadre de l'invention. Bien entendu le dispositif applicateur selon l'invention peut présenter des picots issus des différents modes de réalisation selon l'invention et notamment illustrés et décrits ci-avant.Other non-essential modifications may be provided either on the intrinsic shape of the spikes, or on their orientation and/or reciprocal arrangement, without departing from the scope of the invention. Of course, the applicator device according to the invention may have spikes from the different embodiments according to the invention and in particular illustrated and described above.
