  • Such an applicator is described in particular in EP 1 872 682 .
  • These pins are arranged in rows parallel to the longitudinal axis of the brush, all the pins of a row having their flat face on the same side, that is to say they are aligned and their non-planar faces are on the same side of this line.
  • the brushes of this type do not have maximum efficiency since the rows of spikes comprising only the flat faces of the spikes on one side, do not participate in the separation of the eyelashes and the rows of spikes having only the non-contact faces. Plane eyelashes do not participate in the mascara load.

  • Such a support is shown as always having at least one plane face from which protrude the teeth of two rows.
  • Each row of teeth has staggered teeth on either side of a separation surface so that the teeth may have planar faces opposite one another, that is to say that during a product application with such a comb, the back and forth movement printed with the comb may thus have teeth faces in both directions, adjacent teeth having an axis arranged in different directions.

  • Such a comb has certain advantages but it also has the disadvantages of its advantages. Indeed, it is well known that the mascara which is a relatively viscous fluid tends to dry relatively quickly and we realize very quickly that the sliding of the two parts of the soul will be difficult to implement or even blocked.

Description

La présente invention concerne le domaine des applicateurs de produit cosmétique fluide ou pâteux et plus particulièrement de mascara. L'invention s'intéresse au moyen d'application sous forme de brosse ou de peigne.The present invention relates to the field of applicators of fluid or pasty cosmetic product and more particularly of mascara. The invention is concerned with the application means in the form of a brush or a comb.

On connaît déjà dans l'art antérieur un grand nombre d'applicateurs de mascara. Ces applicateurs comprennent, de manière classique, un corps dont une de ses extrémités est destinée à être fixée à un moyen de préhension manuelle et dont son autre extrémité présente un moyen d'application. Ledit moyen d'application peut être une brosse comprenant une pluralité de picots ou être une pièce moulée en matière plastique présentant des disques tel que décrit dans WO 2006/095973 , FR 2 895 887 , US 2007/0034223 .A large number of mascara applicators are already known in the prior art. These applicators comprise, in a conventional manner, a body whose one end is intended to be attached to a manual gripping means and whose other end has an application means. Said application means may be a brush comprising a plurality of pins or be a molded piece of plastic material having discs as described in WO 2006/095973 , FR 2,895,887 , US 2007/0034223 .

Ledit applicateur forme avec un réservoir à mascara dans lequel il est insérable, un distributeur de mascara, ledit moyen de préhension manuelle du corps servant de capuchon pour le réservoir grâce à des moyens de coopération situés d'une part sur ledit capuchon et d'autre part sur le réservoir à mascara.Said applicator forms with a mascara reservoir in which it is insertable, a mascara dispenser, said manual gripping means of the body serving as a cap for the reservoir by means of cooperation means located on the one hand on said cap and on the other hand share on the mascara tank.

Les inconvénients des brosses de l'art antérieur comprenant des picots, sont que les picots ne permettent pas de réaliser à la fois le transfert du mascara du réservoir sur les picots et l'application du mascara sur les cils (pour les allonger, les épaissir et/ou les séparer) de manière satisfaisante.The disadvantages of the brushes of the prior art, including spikes, are that the spikes do not make it possible to perform both the transfer of the mascara from the reservoir to the spikes and the application of mascara to the eyelashes (to lengthen and thicken them). and / or separate them) satisfactorily.

Une solution apportée par la demande de brevet US 2008/0011317 est une brosse dont la répartition des picots n'est plus faite par rangées uniformes mais est faite par rangées espacées latéralement autour du corps de la brosse selon des angles inégaux d'une rangée à l'autre, des densités de picots différentes, de même que des diamètres et des longueurs de picots différentes. Toutefois, cette solution est relativement complexe et ne permet pas de garantir une charge régulière de mascara sur les cils et/ou sur les picots tout en gardant une séparation suffisante des cils.A solution provided by the patent application US 2008/0011317 is a brush whose distribution of pins is no longer made in uniform rows but is made in rows spaced laterally around the body of the brush at unequal angles from one row to another, different densities of pins, and than different diameters and pin lengths. However, this solution is relatively complex and does not guarantee a regular load of mascara on the eyelashes and / or on the spikes while keeping a sufficient separation of the eyelashes.

Une solution envisagée dans l'art antérieur pour améliorer la charge en mascara des brosses est l'utilisation de picots présentant une face plane pour recueillir le mascara tandis que leur face non plane participe à la séparation des cils. Un tel applicateur est notamment décrit dans EP 1 872 682 . Ces picots sont disposés selon des rangées parallèles à l'axe longitudinal de la brosse, tous les picots d'une rangée présentant leur face plane du même côté, c'est-à-dire qu'elles sont alignées et que leurs faces non planes se trouvent du même côté par rapport à cette ligne. Quand une personne utilisatrice souhaite appliquer du mascara sur ses cils, elle imprime un mouvement de la brosse sur ses cils dans une direction perpendiculaire à l'axe longitudinal de la brosse, en même temps qu'elle fait tourner ladite brosse.A solution envisaged in the prior art for improving the mascara load of the brushes is the use of spikes having a flat face to collect the mascara while their non-planar face participates in the separation of the eyelashes. Such an applicator is described in particular in EP 1 872 682 . These pins are arranged in rows parallel to the longitudinal axis of the brush, all the pins of a row having their flat face on the same side, that is to say they are aligned and their non-planar faces are on the same side of this line. When a user wishes to apply mascara on his eyelashes, it prints a movement of the brush on his eyelashes in a direction perpendicular to the longitudinal axis of the brush, at the same time as it rotates said brush.

Par conséquent, les brosses de ce type ne présentent pas une efficacité maximale puisque les rangées de picots comportant uniquement les faces planes des picots d'un seul côté, ne participent pas à la séparation des cils et les rangées de picots présentant uniquement les faces non planes côté cils ne participent pas à la charge en mascara. Avec ce type de brosse, la personne 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 de mascara.Consequently, the brushes of this type do not have maximum efficiency since the rows of spikes comprising only the flat faces of the spikes on one side, do not participate in the separation of the eyelashes and the rows of spikes having only the non-contact faces. Plane eyelashes do not participate in the mascara load. With this type of brush, the user is therefore forced to make several passes on his eyelashes while reversing the movement of the brush to ensure that a sufficient load of mascara is recovered.

Dans le document EP 1 611 817 , est décrit un dispositif pour l'application d'un produit sur les cils et/ou les sourcils comportant : un support s'étendant selon un axe longitudinal, une première rangée et une deuxième rangée de dents réalisées de manière monolithique avec le support, se raccordant d'un même côté du support et s'étendant sur au moins un quart de la longueur du support, l'une au moins des rangées comportant deux dents s'étendant au moins partiellement de part et d'autre d'une surface géométrique de séparation s'étendant le long de cette rangée, au moins deux dents s'étendant dans des directions non parallèles.In the document EP 1 611 817 , a device for the application of a product on the eyelashes and / or the eyebrows is described comprising: a support extending along a longitudinal axis, a first row and a second row of teeth made monolithically with the support, being connected on the same side of the support and extending over at least a quarter of the length of the support, at least one of the rows comprising two teeth extending at least partially on either side of a surface geometric separation extending along this row, at least two teeth extending in non-parallel directions.

Un tel support est représenté comme ayant toujours au moins une face plane depuis laquelle font saillie les dents de deux rangées. Chaque rangée de dents présente des dents ménagées en quinconce de part et d'autre d'une surface de séparation de sorte que les dents peuvent présenter des faces planes en regard l'une de l'autre, c'est-à-dire que, lors d'une application de produit avec un tel peigne, le mouvement de va et vient imprimé au peigne peut ainsi présenter des faces de dents dans les deux sens, des dents adjacentes ayant un axe ménagé selon des directions différentes.Such a support is shown as always having at least one plane face from which protrude the teeth of two rows. Each row of teeth has staggered teeth on either side of a separation surface so that the teeth may have planar faces opposite one another, that is to say that during a product application with such a comb, the back and forth movement printed with the comb may thus have teeth faces in both directions, adjacent teeth having an axis arranged in different directions.

Ou bien, lorsque les faces planes sont des deux côtés, les dents présentent des directions différentes, ce qui ne permet pas là non plus, une répartition de la charge en mascara et une séparation des cils optimales.Or, when the flat faces are on both sides, the teeth have different directions, which does not allow either, a distribution of the mascara load and optimal separation of eyelashes.

Dans US 5 086 793 , est décrit un peigne dont l'âme est constituée de deux parties montées coulissantes l'une par rapport à l'autre. Au niveau de la jonction entre ces deux parties d'âme des demi-dents de peigne sont ménagées en saillie et présentent une face plane s'étendant normalement à l'âme et alignées selon une ligne centrale de sorte à se trouver ainsi orientées en face à face de part et d'autre de la ligne centrale. Les deux parties de l'âme sont réalisées coulissantes l'une par rapport à l'autre. De cette manière, le coulissement et la forme en demi-dents permet de réaliser un espacement entre les demi-dents qui est modifiable entre un espacement maximal et un espace minimal où les demi-dents se font faces pour ne former qu'une seule dent. Ainsi, il est possible à une utilisatrice de moduler la quantité de mascara entre des dents adjacentes en fonction de l'utilisation voulue. Un tel peigne, les exemples donnés se limitant à cinq rangées de dents, présente certains avantages mais il présente également les inconvénients de ses avantages. En effet, il est bien connu que le mascara qui est un fluide relativement visqueux tend à sécher relativement rapidement et on s'aperçoit très vite que le coulissement des deux parties de l'âme va se trouver difficile à mettre en oeuvre voire même bloqué.In US 5,086,793 is described a comb whose core consists of two parts mounted sliding relative to each other. At the junction between these two parts of the soul comb half-teeth are formed protruding and have a flat face extending normally to the core and aligned along a central line so as to be thus facing the opposite face to side of the central line. The two parts of the soul are realized sliding relative to each other. In this way, the sliding and the half-tooth shape makes it possible to achieve a spacing between the half-teeth that is modifiable between a maximum spacing and a minimum space where the half-teeth are facing to form a single tooth . Thus, it is possible for a user to modulate the amount of mascara between adjacent teeth depending on the intended use. Such a comb, the examples given being limited to five rows of teeth, has certain advantages but it also has the disadvantages of its advantages. Indeed, it is well known that the mascara which is a relatively viscous fluid tends to dry relatively quickly and we realize very quickly that the sliding of the two parts of the soul will be difficult to implement or even blocked.

Dans EP 1 070 468 , est décrite une brosse permettant de maquiller aussi bien les cils que les sourcils avec le même outil et qui permet également de recourber et allonger les cils. Un tel applicateur présente une tige pourvue de rangées de dents présentant une face plane, lesdites faces planes étant ménagées de part et d'autre d'une surface de séparation.In EP 1 070 468 is described a brush for makeup eyelashes as well as eyebrows with the same tool and which also allows to curl and lengthen eyelashes. Such an applicator has a rod provided with rows of teeth having a flat face, said planar faces being formed on either side of a separation surface.

Ces dents s'étendent perpendiculairement à une face lorsque l'âme présente une section transversale polygonale. Cependant lorsque la section transversale de l'âme n'est pas polygonale, soit circulaire, les éléments en saillie s'étendent de manière tangentielle à l'âme. Le maquillage reste toutefois moins performant qu'avec une brosse comportant au moins six rangées de dents tout autour d'une âme.These teeth extend perpendicular to a face when the core has a polygonal cross section. However, when the cross section of the core is not polygonal or circular, the projecting elements extend tangentially to the core. Makeup remains less effective than a brush with at least six rows of teeth all around a soul.

Dans EP 1 070 467 , EP 1 070 466 et WO 01/05274 , on propose des peignes présentant au plus trois rangées de dents et de manière préférée une rangée de dents dans laquelle les dents sont disposées de part et d'autre d'une ligne centrale en regard les unes des autres de manière à former entres elles un interstice formant de réserves de produit. Toutefois, le maquillage nécessite plusieurs applications du fait que l'applicateur est un simple peigne.In EP 1 070 467 , EP 1 070 466 and WO 01/05274 , combs having at most three rows of teeth and preferably a row of teeth in which the teeth are arranged on either side of a central line facing one another so as to form between them a interstice forming product reserves. However, makeup requires several applications because the applicator is a simple comb.

EP 1 342 428 propose notamment un peigne pour les cils et/ou les sourcils. Là encore, on décrit un ensemble de dents dont une face plane est alignée le long d'une surface de séparation. Ces dents s'étendent depuis une face plane d'un support de section polygonale ou bien on propose de réaliser des éléments en saillie depuis une âme de section circulaire ces éléments étant en forme de segments d'arc de cercle. L'objectif d'un tel peigne est de pouvoir moduler l'espace entre les éléments en saillie pour permettre de peigner aussi bien les cils que les sourcils. EP 1 342 428 offers a comb for eyelashes and / or eyebrows. Again, there is described a set of teeth having a planar face aligned along a separation surface. These teeth extend from a flat face of a support of polygonal section or it is proposed to make elements protruding from a core of circular section these elements being in the form of arcuate segments. The purpose of such a comb is to be able to modulate the space between the projecting elements to allow to comb the eyelashes as well as the eyebrows.

L'invention se propose donc de résoudre ces inconvénients grâce à une brosse qui permet de maquiller très avantageusement les cils tout en permettant un dépôt plus simple, plus régulier et avec une charge suffisante. En particulier, l'invention propose une brosse avec laquelle il est possible de définir des zones utilisables pour créer un effet de maquillage particulier.The invention therefore proposes to solve these disadvantages with a brush that makes it possible to make up the eyelashes very advantageously while allowing a simpler, more regular deposit and with sufficient load. In particular, the invention provides a brush with which it is possible to define usable areas to create a particular makeup effect.

L'invention concerne donc un dispositif applicateur tel qu'une brosse d'un produit cosmétique fluide ou pâteux, typiquement du mascara comprenant :

  • une âme constituée d'un corps plastique de section circulaire, flexible, allongé, ayant un axe longitudinal et deux extrémités dont l'une est destinée à être fixée à un moyen de préhension manuelle,
  • une pluralité de picots, présentant une face plane, et ménagés en projection radiale depuis ladite âme, lesdits picots étant répartis selon une pluralité de rangées parallèles à l'axe longitudinal de ladite âme et de telle sorte qu'au sein d'une même rangée, les picots sont positionnés alternativement de part et d'autre d'une ligne centrale de ladite rangée, avec leur face plane tournée vers l'intérieur de la rangée, tel que ledit corps plastique est de forme conique dont le diamètre le plus large est du côté de l'extrémité destinée à être fixée au moyen de préhension manuelle et lesdites faces planes des picots d'une même rangée s'étendent normalement à ladite âme conique, et sont alignées selon la ligne centrale, les faces planes étant ainsi orientées dans les deux sens giratoires autour de l'âme conique.
The invention thus relates to an applicator device such as a brush of a fluid or pasty cosmetic product, typically mascara comprising:
  • a core consisting of a plastic body of circular section, flexible, elongated, having a longitudinal axis and two ends, one of which is intended to be attached to a manual gripping means,
  • a plurality of pins, having a flat face, and arranged in radial projection from said core, said pins being distributed in a plurality of rows parallel to the longitudinal axis of said core and so that within a single row , the pins are positioned alternately on either side of a central line of said row, with their planar face turned towards the inside of the row, such that said plastic body is of conical shape whose widest diameter is on the side of the end intended to be fixed to the manual gripping means and said flat faces of the pins of the same row normally extend to said conical core, and are aligned along the center line, the planar faces being thus oriented in the two roundabouts around the conical soul.

Ainsi de manière avantageuse, la face plane d'un picot alignée sur la ligne centrale de la rangée est alignée « en regard » des faces planes des deux picots adjacents avec un décalage plus ou moins grand, ce qui permet une meilleure charge en mascara tandis que les faces non planes des picots permettent de séparer les cils. La configuration des picots de l'invention permet d'avoir, dans une même rangée et du même côté par rapport à la ligne centrale d'alignement des faces planes, une alternance de faces planes et de faces non planes, les faces planes de deux picots adjacents se trouvant en outre dans le même plan normal à l'âme. De ce fait, entre au moins deux picots adjacents, il n'y a pas d'angle entre les sommets desdits picots par rapport audit plan normal.Thus advantageously, the plane face of a pin aligned with the central line of the row is aligned "facing" the flat faces of the two adjacent pins with a larger or smaller offset, which allows a better load of mascara while that the non-planar faces of the pins can separate the eyelashes. The configuration of the pins of the invention makes it possible to have, in the same row and on the same side relative to the central line of alignment of the planar faces, an alternation of planar faces and of non-planar faces, the plane faces of two Adjacent pimples lying further in the same plane normal to the soul. Therefore, between at least two adjacent pins, there is no angle between the peaks of said pins relative to said normal plane.

Par ailleurs, l'âme conique permet que les picots possèdent tous une embase (une surface à la naissance du picot) différente les uns des autres. De plus, la conicité de l'âme permet que les picots présentent tous une hauteur différente et un espacement différents entre eux, ce qui permet à l'utilisatrice de se servir de l'applicateur dans la zone la mieux adaptée à l'effet de maquillage recherché (la quantité de charge du produit maquillant étant liée à l'espacement et à la hauteur des picots).Furthermore, the conical core allows the pins all have a base (a surface at the birth of the pin) different from each other. In addition, the conicity of the core allows the pins to all have a different height and spacing between them, which allows the user to use the applicator in the area best suited to the effect of desired makeup (the amount of makeup product load being related to the spacing and height of the pimples).

Aussi, la brosse selon l'invention présente des caractéristiques permettant facilement des effets de maquillage tout en offrant un maquillage simple et rapide.Also, the brush according to the invention has characteristics allowing easy makeup effects while providing a simple and fast makeup.

Cette âme conique facilite et sécurise en outre l'introduction de l'applicateur dans un organe d'essorage ou essoreur et limite ainsi la flexion de l'applicateur lorsque celui-ci vient en appui dans la jupe de l'essoreur prévu sur un réservoir de produit lors de l'introduction.This conical core further facilitates and secures the introduction of the applicator into a wiper or wiper member and thus limits the bending of the applicator when it is resting in the skirt of the wiper provided on a reservoir of product during the introduction.

La forme conique du corps de la brosse permet avec un matériau souple d'avoir malgré tout, une certaine rigidité. Cette âme ou poutre conique est donc plus rigide et résiste mieux à la compression et à la flexion lorsque l'on applique une poussée sur le coté du petit diamètre.The conical shape of the body of the brush allows with a flexible material to have anyway, a certain rigidity. This conical core or beam is therefore more rigid and better resists compression and flexion when applying a thrust on the side of the small diameter.

L'applicateur selon l'invention possède ainsi une rigidité progressive depuis son extrémité (petit diamètre du cône) jusqu'au raccordement sur sa tige (grand diamètre du cône)The applicator according to the invention thus has a progressive rigidity from its end (small diameter of the cone) to the connection on its stem (large diameter of the cone)

Selon une première forme de réalisation, les axes des picots d'une même rangée sont tous parallèles, cet axe étant l'axe de symétrie ou ligne formant le centre de gravité de la projection de la forme du picot. Les picots sont donc tous orientés dans la même direction par rapport à l'âme.According to a first embodiment, the axes of the pins of the same row are all parallel, this axis being the axis of symmetry or line forming the center of gravity of the projection of the shape of the pin. The pins are therefore all oriented in the same direction relative to the soul.

Selon une autre forme de réalisation, les axes des picots se trouvant du même côté de la ligne centrale de la rangée sont parallèles entre eux tandis que les axes des picots se trouvant de l'autre côté de la ligne centrale de la rangée sont parallèles entre eux, selon une direction différente.According to another embodiment, the pins of the pins on the same side of the central line of the row are parallel to each other while the pins of the pins located on the other side of the center line of the row are parallel between them, according to a different direction.

Le dispositif applicateur selon l'invention est une brosse et présente de 5 à 16, voire même 24 rangées de picots.The applicator device according to the invention is a brush and has from 5 to 16, or even 24 rows of pins.

La densité de rangées de picots qui sont réparties angulairement de manière régulière autour de l'âme permet de moduler les propriétés de la brosse à savoir sa précision, sa capacité de séparation et sa capacité de charge en produit. On conserve une hauteur de charge suffisante et régulière non perturbée par l'essorage.The density of rows of pins which are distributed angularly in a regular manner around the core makes it possible to modulate the properties of the brush, namely its accuracy, its separation capacity and its load capacity in product. Keep a sufficient and regular load height undisturbed by the spin.

Lorsqu'une personne utilise la brosse de l'invention pour appliquer du mascara sur ses cils et qu'elle imprime un mouvement de la brosse sur les cils, perpendiculaire à l'axe longitudinal du corps de la brosse, du fait de la présence, dans une rangée de picots, d'une alternance de faces planes et de faces non planes, selon les deux sens giratoires autour de l'âme, il y aura obligatoirement, face aux cils et pour chaque rangée, des faces planes chargées de mascara et des faces non planes pour la séparation des cils. La brosse objet de l'invention permet donc, tout en gardant une bonne séparation des cils grâce aux faces non planes, d'avoir une bonne charge de mascara déposée sur les cils et ce, quelque soit l'habileté de la personne utilisant la brosse.When a person uses the brush of the invention to apply mascara on his eyelashes and that it prints a movement of the brush on the eyelashes, perpendicular to the longitudinal axis of the body of the brush, due to the presence, in a row of pins, an alternation of flat faces and non-planar faces, according to the two revolving directions around the soul, there will be obligatorily, facing the eyelashes and for each row, flat faces loaded with mascara and non-planar faces for the separation of the eyelashes. The brush object of the invention thus makes it possible keeping a good separation of the eyelashes thanks to the non-flat faces, to have a good load of mascara deposited on the eyelashes and this, whatever the skill of the person using the brush.

Dans une forme d'exécution particulière de l'invention, les faces planes de deux picots adjacents d'une même rangée se chevauchent au moins partiellement. Ce chevauchement permet d'augmenter la rigidité du picot sans augmenter le profil d'attaque en contact avec le cil.In a particular embodiment of the invention, the flat faces of two adjacent pins of the same row overlap at least partially. This overlap makes it possible to increase the stiffness of the pin without increasing the attack profile in contact with the eyelash.

Dans une forme d'exécution particulière de l'invention, les picots d'une même rangée sont répartis de manière non uniforme le long de ladite rangée. Ainsi, plusieurs configurations sont possibles comme de grouper dans une même rangée deux picots adjacents séparés par un espace, d'un autre groupe de deux picots adjacents. Suivant la fonction souhaitée de la brosse, l'écartement entre les groupes de picots et le nombre de picots par groupe peut varier. On peut aussi envisager un groupe de picots avec la même configuration, face non plane du même côté de la ligne centrale de la rangée, puis un groupe de picots avec la face non plane de l'autre côté de la ligne centrale.In a particular embodiment of the invention, the pins of the same row are non-uniformly distributed along said row. Thus, several configurations are possible as to group in the same row two adjacent pins separated by a space, another group of two adjacent pins. Depending on the desired function of the brush, the spacing between the groups of pins and the number of pins per group may vary. One can also consider a group of pins with the same configuration, non-flat face on the same side of the center line of the row, then a group of pins with the non-planar face on the other side of the center line.

De même, on peut envisager qu'au sein d'une rangée, d'un même côté de la ligne centrale de séparation, deux picots adjacents présentent un axe parallèle et qu'au moins un autre picot présente un axe de direction différente.Similarly, it is conceivable that within a row, on the same side of the central separation line, two adjacent pins have a parallel axis and at least one other pin has a different axis of direction.

Ainsi, l'implantation des picots dans une même rangée peut être réalisée de manière uniforme et régulière, l'espace entre les picots étant toujours identique, qu'ils se chevauchent ou pas. Cette implantation peut également être régulière mais non uniforme.Thus, the implantation of the pins in the same row can be performed in a uniform and regular manner, the space between the pins being always the same whether they overlap or not. This implantation can also be regular but not uniform.

De manière avantageuse, sur un dispositif applicateur selon l'invention, il est également possible de prévoir que certaines rangées présentent des picots dont les faces planes sont orientées dans les deux sens giratoires autour de l'âme et des rangées dont tous les picots présentent des faces planes orientées dans un seul sens giratoire autour de l'âme.Advantageously, on an applicator device according to the invention, it is also possible to provide that certain rows have pins whose planar faces are oriented in the two gyratory directions around the core and the rows of which all the pins have planar faces oriented in a single gyrating direction around the soul.

Dans un mode de réalisation de l'invention, les picots présentent une hauteur différente par rapport au corps et les pointes desdits picots alignées définissent une surface d'enveloppe de la brosse.In one embodiment of the invention, the pins have a different height relative to the body and the tips of said aligned pins define an envelope surface of the brush.

Dans une forme d'exécution particulièrement préférée de l'invention, les picots sont ménagés coniques depuis l'âme, avec une section transversale circulaire, polygonale tel que triangulaire, toujours au moins avec une face plane qui sera alignée sur la ligne centrale de la rangée.In a particularly preferred embodiment of the invention, the spikes are formed conically from the core, with a circular, polygonal cross-section such as triangular, always at least with a flat face that will be aligned with the center line of the spine. row.

Dans une forme de réalisation de la présente invention, les picots sont formés de deux matériaux distincts, le premier matériau formant le noyau du picot et le deuxième matériau formant l'écorce autour dudit noyau.In one embodiment of the present invention, the spikes are formed of two distinct materials, the first material forming the core of the spike and the second material forming the bark around said core.

L'intérêt d'utiliser deux matériaux différents est de proposer deux souplesses et deux sensations de touché différentes sur un même applicateur qui peuvent de plus être repérées par exemple par deux teintes différentes.The advantage of using two different materials is to provide two flexibility and two different touch sensations on the same applicator that can be further identified for example by two different colors.

Selon une autre forme de réalisation, on prévoit que sur sa face plane, un picot comporte un creux constituant un réservoir supplémentaire pour retenir le produit et favoriser la charge de l'applicateur.According to another embodiment, it is provided that on its flat face, a pin comprises a hollow constituting an additional reservoir for retaining the product and promote the charging of the applicator.

Dans une forme d'exécution, les picots présentent des diamètres différents au niveau de leur implantation sur l'âme ce qui permet de faire varier la charge et la souplesse.In one embodiment, the pins have different diameters at their implantation on the core which allows to vary the load and flexibility.

L'invention concerne également un applicateur de produit cosmétique comprenant :

  • ledit dispositif applicateur selon l'invention, et
  • un moyen de préhension manuelle adapté à être fixé à une extrémité du corps de ladite brosse.
The invention also relates to a cosmetic product applicator comprising:
  • said applicator device according to the invention, and
  • manual gripping means adapted to be attached to one end of the body of said brush.

Enfin, l'invention concerne un distributeur de produit cosmétique comprenant un réservoir apte à contenir ledit produit cosmétique et l'applicateur selon l'invention, le moyen de préhension manuelle dudit applicateur servant de capuchon destiné à fermer le réservoir.Finally, the invention relates to a cosmetic product dispenser comprising a reservoir adapted to contain said cosmetic product and the applicator according to the invention, the manual gripping means of said applicator serving as a cap for closing the reservoir.

La Figure 1 représente un applicateur de mascara tel qu'une brosse 1 présentant deux extrémités 2 et 3. L'extrémité 3 est destinée à être fixée sur un moyen de préhension manuelle (non représenté) et l'extrémité 2 est celle qui pénètre en premier dans le réservoir de mascara (non représenté).The Figure 1 represents a mascara applicator such as a brush 1 having two ends 2 and 3. The end 3 is intended to be fixed on a manual gripping means (not shown) and the end 2 is the one that enters first into the mascara tank (not shown).

La brosse 1 comprend une âme ou corps 4 tubulaire de section circulaire, conique, allongé, flexible, pouvant être en matière plastique. Ce corps 4 présente un axe longitudinal X-X'. Une pluralité de picots 5 sont ménagés en projection radiale depuis le corps 4 et sont répartis sur l'ensemble de la circonférence du corps 4 (voir la Figure 2).The brush 1 comprises a core or tubular body 4 of circular section, conical, elongated, flexible, which may be of plastic. This body 4 has a longitudinal axis X-X '. A a plurality of pins 5 are formed in radial projection from the body 4 and are distributed over the entire circumference of the body 4 (see FIG. Figure 2 ).

Ces picots 5 sont agencés selon des rangées 6 s'étendant parallèles à l'axe X-X'sur l'âme 4. Chaque picot 5 présente une face plane 7 et une face non plane, par exemple arrondie 8 de sorte que les picots 5 présentent une forme extérieure de demi-cône.These pins 5 are arranged in rows 6 extending parallel to the axis X-X 'on the core 4. Each pin 5 has a flat face 7 and a non-planar face, for example rounded 8 so that the pins 5 have an outer half-cone shape.

Les picots 5 d'une même rangée 6 ont leurs faces planes alignées sur une même ligne centrale 9 de la rangée 6, et s'étendant normalement à ladite ligne centrale, les faces arrondies 8 étant situées de part et d'autre de ladite ligne 9, successivement d'un côté puis de l'autre.The pins 5 of the same row 6 have their flat faces aligned on the same central line 9 of the row 6, and extending normally to said central line, the rounded faces 8 being located on either side of said line 9, successively on one side then the other.

De cette manière, dans une même rangée 6, des faces planes 7 se trouvent dans un même plan normal à l'âme, dans les deux sens giratoires autour de l'âme 4.In this way, in the same row 6, planar faces 7 are in the same plane normal to the core, in the two gyratory directions around the core 4.

Les axes des picots 5 d'une même rangée 6 sont tous parallèles, cet axe étant l'axe de symétrie ou ligne formant le centre de gravité de la projection de la forme du picot 5. Les picots 5 sont donc tous orientés dans la même direction par rapport à l'âme 4, cette direction étant ici confondue avec la normale à l'âme 4.The axes of the pins 5 of the same row 6 are all parallel, this axis being the axis of symmetry or line forming the center of gravity of the projection of the shape of the pin 5. The pins 5 are all oriented in the same direction with respect to the soul 4, this direction being here confused with the normal to the core 4.

En pratique, l'applicateur formé de la brosse 1 et du moyen de préhension manuelle (non représenté) est placé dans un réservoir de mascara (non représenté) formant un distributeur de produit cosmétique fermé (le moyen de préhension manuelle servant généralement également de capuchon pour fermer ledit réservoir).In practice, the applicator formed of the brush 1 and the manual gripping means (not shown) is placed in a mascara reservoir (not shown) forming a closed cosmetic product dispenser (the manual gripping means also serving generally as a cap to close said reservoir).

Puis, lorsqu'une personne souhaite utiliser l'applicateur, on sort la brosse 1 du réservoir, les faces planes 7 de chaque picot 5 étant pourvues d'une certaine quantité de mascara bien plus importante que la quantité retenue par les faces arrondies 8. La personne applique alors la brosse 1 sur ses cils en plaçant l'axe longitudinal X-X' de la brosse 1 perpendiculaire à l'axe longitudinal des cils puis en effectuant des mouvements de la brosse 1 selon l'axe longitudinal des cils tout en appliquant un mouvement de rotation à ladite brosse 1 autour de son axe longitudinal X-X'.Then, when a person wishes to use the applicator, the brush 1 is taken out of the reservoir, the flat faces 7 of each pin 5 being provided with a certain amount of mascara much larger than the quantity retained by the rounded faces 8. The person then applies the brush 1 on his eyelashes by placing the longitudinal axis XX 'of the brush 1 perpendicular to the longitudinal axis of the eyelashes and then making movements of the brush 1 along the longitudinal axis of the eyelashes while applying a rotational movement to said brush 1 about its longitudinal axis X-X '.

On comprend que les faces planes 7 qui se trouvent côté cils permettent une bonne charge de mascara sur les cils tandis que les faces arrondies 8 qui se trouvent côté cils permettent une bonne séparation des mêmes cils. Du fait de la répartition des faces arrondies 8 d'un côté puis de l'autre de la ligne 9, il y aura obligatoirement une partie, par exemple, la moitié des picots 5 d'une même rangée 6 qui présentent, face aux cils, une face plane 7 chargée de mascara et l'autre partie, donc par exemple l'autre moitié, des picots 5 qui présentent, face aux cils, une face arrondie.It is understood that the flat faces 7 which are on the eyelashes side allow a good load of mascara on the eyelashes while the rounded faces 8 which are on the eyelashes side allow a good separation of the same eyelashes. Due to the distribution of the rounded faces 8 on one side then the other of the line 9, there will necessarily be a part, for example, half of the pins 5 of the same row 6 which have, facing the eyelashes, a flat face 7 loaded with mascara and the other part, so for example the other half, pins 5 which have, facing the eyelashes, a rounded face.

Ainsi, quelque soit le sens d'entraînement en rotation et/ou translation de la brosse 1 imprimé par l'utilisatrice, pour appliquer le mascara sur les cils, chaque rangée 6 participe à la fois à la charge en mascara et à la séparation des cils.Thus, whatever the direction of rotation and / or translation of the brush 1 printed by the user, to apply the mascara to the eyelashes, each row 6 participates in both the mascara load and the separation of the mascara. lashes.

La figure 3a est un premier mode de réalisation de la brosse 1 de l'invention. Dans ce mode de réalisation, les picots 5 sont répartis uniformément le long de la ligne centrale 9 de la rangée 6. Uniformément signifie ici que les picots 5 sont alternés un sur un et tous côte à côte.The figure 3a is a first embodiment of the brush 1 of the invention. In this embodiment, the pins 5 are evenly distributed along the center line 9 of the row 6. Uniformly here means that the pins 5 are alternated one by one and all side by side.

Dans une forme d'exécution particulière de ce premier mode de réalisation, les faces 7 de deux picots 5 adjacents peuvent se chevaucher au moins partiellement comme on peut le voir sur la figure 3c pour le groupe de deux picots C. Ce chevauchement permet d'augmenter la rigidité des picots 5 sans augmenter le profil d'attaque en contact avec le cil. Dans certaines rangées 6, on peut même insérer deux picots 5 se chevauchant totalement (groupe D de la figure 3c).In a particular embodiment of this first embodiment, the faces 7 of two adjacent pins 5 may overlap at least partially as can be seen in FIG. figure 3c for the group of two pins C. This overlap makes it possible to increase the stiffness of the pins 5 without increasing the attack profile in contact with the eyelash. In some rows 6, it is possible to insert two completely overlapping pins 5 (group D of the figure 3c ).

La figure 3b représente un deuxième mode de réalisation de l'invention. Dans ce mode de réalisation, les picots 5 sont adjacents par groupe de 2 et un écart sépare chaque groupe du groupe suivant.The figure 3b represents a second embodiment of the invention. In this embodiment, the pins 5 are adjacent in groups of 2 and a gap separates each group from the next group.

Sur les figures 4a, 4b et 4c sont représentés différentes sections transversales possibles pour réaliser les picots 5. Ainsi à la figure 4a, les picots 5 ont une section semi-circulaires et les picots 5', une section triangulaire. A la figure 4b, la rangée 6 présente les mêmes picots 5 en alternance avec des picots 5" avec un rayon de courbure différent. A la figure 4c, la rangée 6 présente une alternance de picots 5 et de picots 5'" de section semi-circulaire mais de diamètre différent.On the Figures 4a, 4b and 4c are represented different possible cross sections for making the pins 5. Thus at the figure 4a , the pins 5 have a semicircular section and the pins 5 ', a triangular section. To the figure 4b the row 6 has the same pins 5 alternating with pins 5 "with a different radius of curvature. figure 4c the row 6 has an alternation of pins 5 and pins 5 '' of semicircular section but of different diameter.

L'ensemble des sommets des picots 5 d'une brosse 1 définit une forme de surface de la brosse qu'on appelle surface d'enveloppe. Comme on peut le voir aux figures 7 et 8, les picots 5 peuvent présenter eux-mêmes des formes et des dimensions différentes au sein d'une même rangée 6.The set of peaks of the pins 5 of a brush 1 defines a surface shape of the brush which is called the envelope surface. As can be seen at Figures 7 and 8 , the pins 5 may themselves have different shapes and dimensions within the same row 6.

Les figures 5a à 5g montrent plusieurs brosses 1a, 1b, 1c, 1d, 1e, 1f et 1g présentant respectivement une forme de surface d'enveloppe différente (représentée en pointillés) définie par l'alignement des sommets des picots 5.The Figures 5a to 5g show a plurality of brushes 1a, 1b, 1c, 1d, 1e, 1f and 1g respectively having a different envelope surface shape (shown in dotted lines) defined by the alignment of the peaks of the pins 5.

Ces différentes formes de surface d'enveloppes permettent de moduler les propriétés de la brosse en ce qui concerne sa précision, son pouvoir de séparation des cils ou la charge.These different forms of envelope surface can modulate the properties of the brush with regard to its precision, its power of separation of the eyelashes or the load.

De même, comme on peut le voir aux figures 6a à 6f, la forme en section transversale de ladite brosse peut elle aussi être variée en fonction de l'organisation des longueurs de picots 5 de chaque rangée 6 et de la densité des rangées 6 également.Similarly, as can be seen at Figures 6a to 6f the cross-sectional shape of said brush may also be varied depending on the arrangement of the spike lengths of each row 6 and the density of the rows 6 as well.

La figure 9 représente une brosse 1 avec une densité de rangées 6 élevée, chaque rangée 6 étant pourvue de picots 5 espacés régulièrement. Les rangées 6 de picots 5 sont réparties angulairement de manière régulière autour de l'âme 4.The figure 9 represents a brush 1 with a high row density 6, each row 6 being provided with pins 5 spaced regularly. The rows 6 of pins 5 are distributed angularly in a regular manner around the core 4.

Dans la figure 10, la brosse 1 comporte une densité de rangées 6 plus faible mais chaque rangée 6 est pourvue de picots 5 associés par groupe de deux, l'intervalle entre chaque groupe étant supérieur à l'intervalle entre les picots d'un même groupe.In the figure 10 , the brush 1 has a lower row density 6 but each row 6 is provided with associated pins 5 in groups of two, the interval between each group being greater than the interval between the pins of the same group.

Dans une forme de réalisation, les axes des picots 5 se trouvant du même côté de la ligne centrale de la rangée 6 sont parallèles entre eux tandis que les axes des picots 5' se trouvant de l'autre côté de la ligne centrale de la rangée 6 sont parallèles entre eux, selon une direction différente.In one embodiment, the axes of the pins 5 on the same side of the center line of the row 6 are parallel to each other while the axes of the pins 5 'are on the other side of the center line of the row. 6 are parallel to each other in a different direction.

De telles formes de réalisations sont représentées dans les figures 11a et 11b, 12a et 12b, 13a et 13b, 14a et 14b.Such embodiments are represented in the Figures 11a and 11b , 12a and 12b , 13a and 13b , 14a and 14b .

On peut y voir que les faces planes de chaque picot 5, 5' sont bien alignées sur la ligne centrale de la rangée 6 dans le même plan normal à l'âme 4 conique mais que les axes de picots 5 s'étendent parallèles entre eux, mais selon une direction différente de celle des picots 5' également parallèles entre eux.It can be seen that the flat faces of each pin 5, 5 'are well aligned on the center line of the row 6 in the same plane normal to the conical core 4 but that the pin axes 5 extend parallel to each other but in a direction different from that of the pins 5 'also parallel to each other.

Cette direction peut être elle aussi normale à l'âme 4 mais elle peut également former un angle α, avec celle-ci, et des angles α différents.This direction may also be normal to the core 4 but it may also form an angle α with it, and different angles α.

Il est bien entendu que l'invention n'est pas limitée aux modes de réalisation décrits et représentés. L'invention est définie seulement par les revendications annexées.It is understood that the invention is not limited to the embodiments described and shown. The invention is defined only by the appended claims.
