A second brush (6) has a twisted frame (7) with a second bristle carrying portion also having radial bristles. The two brushes are wound around each other so that the bristle carrying portions are twisted over each other for a constant relative spacing.

Description

La présente invention a trait à un applicateur de produit cosmétique, notamment de mascara, tel qu'utilisé en particulier pour les cils et les sourcils.The present invention relates to a cosmetic product applicator, in particular mascara, as used in particular for eyelashes and eyebrows.

Dans le domaine du mascara, les applicateurs les plus communément utilisés sont formés de brosses dites " torsadées". De telles brosses torsadées sont obtenues en disposant une nappe de poils entre les deux branches d'un fil de fer configuré en épingle à cheveux, puis en torsadant les deux branches du fil de fer autour de son axe. Le fil de fer ainsi torsadé forme une hélice (en réalité, une pour chaque brin de fil de fer) dont les spires, en fonction du sens de torsadage du fil de fer, montent de la gauche vers la droite (lorsque la brosse est vue de face en position verticale) ou de la droite vers la gauche. Le premier type de torsadage permet d'obtenir une brosse qualifiée parfois de "brosse gauche". Une telle brosse est décrite notamment dans le brevet EP 0 611 170 au nom de la demanderesse. Le second type de torsadage, le plus répandu jusqu'à présent, permet d'obtenir une brosse qualifiée de "brosse droite".In the field of mascara, the most commonly used applicators are formed of so-called "twisted" brushes. Such twisted brushes are obtained by arranging a sheet of bristles between the two branches of a wire configured hairpin, and then twisting the two branches of the wire about its axis. The wire thus twisted forms a helix (in fact, one for each strand of wire) whose turns, depending on the direction of twisting of the wire, rise from left to right (when the brush is seen from the front in a vertical position) or from right to left. The first type of twisting provides a brush sometimes qualified "left brush". Such a brush is described in particular in patent EP 0 611 170 in the name of the applicant. The second type of twisting, the most widespread so far, provides a brush called "brush right".

De telles brosses torsadées comprennent généralement une partie "empoilée" définissant une portion d'application, se prolongeant par une partie "non empoilée" du fil de fer, appelée parfois "queue" de la brosse, et servant notamment à la fixation du dispositif sur une tige reliée notamment à un organe pour la préhension du dispositif.Such twisted brushes generally comprise a portion "empoilée" defining an application portion, extending by a "nonempoilée" portion of the wire, sometimes called "tail" of the brush, and serving in particular for fixing the device on a rod connected in particular to an organ for gripping the device.

Ces quinze dernières années ont vu l'apparition de brosses torsadées de sections et formes variables, utilisant des poils plus ou moins gros, en plus ou moins grand nombre, et de nature variable. Toutes ces modifications visent à modifier le maquillage pouvant être obtenu avec une telle brosse, en prenant en considération notamment, la rhéologie du produit à appliquer.During the last fifteen years, twisted brushes of various shapes and sizes have appeared, using more or less large hairs, in varying degrees, and of variable nature. All these modifications are aimed at modifying the makeup obtainable with such a brush, taking into account in particular the rheology of the product to be applied.

En fonction de la configuration de la brosse torsadée, il est ainsi possible de jouer sur la charge de produit, sur la séparation des cils, sur leur allongement ou sur leur recourbement. Les possibilités ne sont toutefois pas infinies.Depending on the configuration of the twisted brush, it is thus possible to play on the product load, on the separation of the eyelashes, on their elongation or on their bending. The possibilities are not infinite, however.

Dans l'un des modes de réalisation du document EP 0 717 944, il est décrit un applicateur formé par repliement sur elle même d'une brosse torsadée, sensiblement à la moitié de sa longueur, puis par une rotation de 180° de l'une des demi-branches autour de l'autre. Au final, il en résulte un applicateur formant deux boucles, destinées à former un réservoir de produit. Au point de croisement des demi-branches, la distance de l'une par rapport à l'autre est sensiblement nulle. Ensuite cette distance augmente progressivement de part et d'autre du point de croisement pour atteindre un maximal avant de diminuer, d'une part en direction de la zone de repliement, et d'autre part, en direction d'une zone ou les deux demi-branches sont non torsadées et parallèles l'une relativement à l'autre.In one of the embodiments of the document EP 0 717 944, there is described an applicator formed by folding over itself a twisted brush, substantially at half of its length, then by a 180 ° rotation of the one of the half-branches around the other. In the end, this results in an applicator forming two loops, intended to form a product reservoir. At the point of intersection of the half-branches, the distance from one relative to the other is substantially zero. Then this distance increases progressively on both sides of the crossing point to reach a maximum before decreasing, on the one hand in the direction of the folding zone, and on the other hand, in the direction of an area where both Half-branches are not twisted and parallel to each other.

Une difficulté majeure d'une telle configuration tient à son encombrement, transversalement à l'axe de la brosse, lequel encombrement pose problème notamment pour l'introduction et le passage de la brosse dans l'organe d'essorage. En outre, la fabrication d'un tel applicateur de manière automatisée est des plus problématiques.A major difficulty of such a configuration is its size, transversely to the axis of the brush, which congestion poses a problem especially for the introduction and passage of the brush in the wiper member. In addition, the manufacture of such an applicator in an automated manner is most problematic.

Ainsi, dans un domaine toujours en quête de nouveaux effets cosmétiques et/ou esthétiques, l'invention vise à réaliser un nouvel applicateur offrant, par rapport aux applicateurs connus, d'autres possibilités encore en termes de maquillage, notamment des cils ou des sourcils.Thus, in a field still in search of new cosmetic and / or aesthetic effects, the invention aims to achieve a new applicator offering, compared to known applicators, other possibilities still in terms of makeup, including eyelashes or eyebrows .

Un autre objet de l'invention vise à réaliser un applicateur qui soit économique à réaliser et simple d'utilisation.Another object of the invention is to provide an applicator that is economical to produce and easy to use.

D'autres objets encore apparaîtront dans la description détaillée qui suit.Still other objects will appear in the following detailed description.

Selon l'invention, ces objets sont atteints en réalisant un applicateur de produit cosmétique, notamment de mascara comprenant :

  • a) une première brosse formée d'une première âme torsadée qui, sur une première portion empoilée, emprisonne des poils disposés de manière radiale relativement à l'âme ;
  • b) une seconde brosse formée d'une seconde âme torsadée qui, sur une seconde portion empoilée, emprisonne des poils disposés de manière radiale relativement à l'âme ;
lesdites première et seconde brosses étant enroulées l'une autour de l'autre de sorte que sur au moins une portion empoilée de l'applicateur, les première et seconde âmes soient torsadées l'une relativement à l'autre en s'étendant à distance l'une de l'autre sensiblement constante.According to the invention, these objects are achieved by producing a cosmetic product applicator, in particular mascara, comprising:
  • a) a first brush formed of a first twisted core which, on a first empoilated portion, traps bristles arranged radially relative to the core;
  • b) a second brush formed of a second twisted core which, on a second empoilated portion, traps bristles arranged radially relative to the core;
said first and second brushes being wound around each other so that on at least one empoiled portion of the applicator, the first and second webs are twisted relative to one another by extending at a distance one of the other substantially constant.

Ainsi, à la différence du document EP-A1-0 717 944, dans laquelle la brosse était repliée, puis tournée de 180° de manière à former deux boucles ouvertes, selon l'invention, les deux brosses torsadées sont enroulées l'une relativement à l'autre de sorte que leurs âmes respectives, sur la portion torsadée, progressent à distance constante l'une de l'autre.Thus, unlike the document EP-A1-0 717 944, in which the brush was folded and then rotated 180 ° so as to form two open loops, according to the invention, the two twisted brushes are wound one relatively to the other so that their respective souls, on the twisted portion, progress at a constant distance from each other.

Une telle distance constante entre les deux âmes torsadées s'obtient notamment en maintenant les deux premières extrémités de deux brosses parallèles disposées aussi proche que possible l'une de l'autre, au moyen d'un mors fixe en rotation, et les deux secondes extrémités des deux brosses au moyen d'un mors entraîné en rotation relativement au premier. Les deux brosses peuvent être solidaires l'une de l'autre au niveau d'une zone de repliement d'une brosse de départ de longueur double.Such a constant distance between the two twisted cores is obtained in particular by maintaining the first two ends of two parallel brushes arranged as close as possible to one another, by means of a fixed jaw in rotation, and the two seconds ends of the two brushes by means of a jaw rotated relative to the first. The two brushes can be secured to one another at a folding zone of a double length starting brush.

De préférence, les deux âmes torsadées sont enroulées d'au moins 1 tour (360°) l'une autour de l'autre. De préférence encore, elles sont enroulées d'au moins 1,5 tour, et, de préférence encore, d'au moins deux tours.Preferably, the two twisted cores are wound at least 1 turn (360 °) around each other. More preferably, they are wound at least 1.5 turns, and more preferably at least two turns.

De préférence, les deux brosses avant d'être torsadées l'une autour de l'autre, sont de longueur totale sensiblement identique, les longueurs respectives de leurs portions empoilées et de leurs portions non empoilées étant par ailleurs généralement identiques.Preferably, the two brushes before being twisted one around the other, are of substantially identical total length, the respective lengths of their empoilées portions and their non-empoilé portions being otherwise generally identical.

Lors du torsadage, les brosses peuvent avoir leurs portions empoilées respectives ainsi que leurs portions non empoilées respectives en superposition axiale sensible ou être décalées axialement de sorte que les âmes des deux brosses de départ sont torsadées l'une relativement à l'autre, seulement sur une portion de longueur totale de la portion empoilée de l'applicateur.During twisting, the brushes can have their respective empoilated portions and their respective non-empoilées portions in sensitive axial superposition or be axially offset so that the webs of the two brushes are twisted relative to each other, only over a portion of the total length of the empoiled portion of the applicator.

De préférence, chacune des première et seconde brosses de départ comprend une première extrémité libre située du côté de la portion empoilée opposé à la queue. De même, chacune des première et seconde brosses comprend une seconde extrémité libre située du côté de la queue opposé à la portion empoilée.Preferably, each of the first and second starting brushes comprises a first free end located on the side of the empoiled portion opposite the tail. Similarly, each of the first and second brushes comprises a second free end located on the side of the tail opposite the empoilated portion.

L'applicateur selon l'invention permet de générer de multiples nouvelles géométries et configurations de poils, lesquelles géométries et configurations nouvelles offrent autant de nouvelles possibilités en termes de maquillage.The applicator according to the invention makes it possible to generate multiple new geometries and hair configurations, which new geometries and configurations offer as many new possibilities in terms of makeup.

Ces nouvelles géométries et configurations résultent notamment du fait que les spires de chacune des brosses vont, lors du torsadage de la première brosse relativement à la seconde, s'imbriquer entre elles, s'écraser en partie, et, de ce fait, avoir un comportement nouveau lorsqu'elles vont être mises en engagement avec les cils ou les sourcils en vue d'une application d'un produit de soin ou de maquillage.These new geometries and configurations result in particular from the fact that the turns of each of the brushes go, when twisting the first brush relative to the second, to interlock with each other, to crush in part, and, therefore, to have a new behavior when they will be put in engagement with the eyelashes or the eyebrows with a view to an application of a product of care or makeup.

Bien évidemment, le degré d'imbrication des spires entre elles dépend de nombreux paramètres, et en particulier de la configuration de chacune des première et seconde brosses et de la façon dont elles sont torsadées l'une relativement à l'autre (notamment, le pas de la torsade).Of course, the degree of nesting of the turns between them depends on many parameters, and in particular on the configuration of each of the first and second brushes and the manner in which they are twisted relative to each other (in particular, the not twisted).

De préférence, la portion empoilée de l'applicateur est solidaire d'une portion non empoilée, la portion non empoilée résultant du torsadage de première et seconde portions non empoilées des première et seconde âmes torsadées. Ainsi, la portion non empoilée de l'apalicateur est formée à partir du torsadage de quatre brins de fils de fer pré-torsadés deux à deux.Preferably, the empoilated portion of the applicator is integral with a non-potted portion, the non-pocketed portion resulting from the twisting of first and second unpouched portions of the first and second twisted cores. Thus, the unpouched portion of the apalicator is formed from the twisting of four strands of iron son pre-twisted two by two.

Avantageusement, la portion non empoilée de l'applicateur est solidaire d'une tige, qui, de préférence, est solidaire d'un capuchon d'une unité de conditionnement et d'application à laquelle est destiné l'applicateur.Advantageously, the unpouched portion of the applicator is integral with a rod, which preferably is secured to a cap of a packaging unit and application to which is intended the applicator.

Généralement, le montage de l'applicateur sur la tige se fait par insertion de l'extrémité libre de la queue de l'applicateur dans un alésage borgne ménagé dans l'axe de la tige, l'extrémité de cette dernière (ou la queue de l'applicateur) étant chauffée de manière à ramollir le matériau thermoplastique formant la tige et à faciliter le montage de l'applicateur sur la tige.Generally, the mounting of the applicator on the rod is done by insertion of the free end of the tail of the applicator into a blind bore formed in the axis of the rod, the end of the latter (or the tail the applicator) being heated so as to soften the thermoplastic material forming the rod and to facilitate the mounting of the applicator on the rod.

Selon un mode de réalisation particulier, avant torsadage de la première brosse autour de la seconde, une section de la première brosse selon un plan contenant la première âme torsadée est sensiblement identique à une section de la seconde brosse selon un plan contenant la seconde âme torsadée. Ainsi, les deux brosses peuvent être notamment cylindriques, tronconiques, ou cylindro-tronconiques.According to a particular embodiment, before twisting the first brush around the second, a section of the first brush in a plane containing the first twisted core is substantially identical to a section of the second brush in a plane containing the second twisted core . Thus, the two brushes can be in particular cylindrical, frustoconical, or cylindro-frustoconical.

Alternativement, avant torsadage de la première brosse autour de la seconde, une section de la première brosse selon un Plan contenant la première âme torsadée est différente d'une section de la seconde brosse selon un plan contenant la seconde âme torsadée. Ainsi, la première brosse peut être de forme cylindro-tronconique, la seconde brosse étant en forme de cacahuète.Alternatively, before twisting the first brush around the second, a section of the first brush in a plane containing the first twisted core is different from a section of the second brush in a plane containing the second twisted core. Thus, the first brush may be cylindro-frustoconical, the second brush being peanut-shaped.

Les première et seconde brosses peuvent être des brosses "droites". Alternativement, les première et seconde brosses sont des brosses "gauches".The first and second brushes may be "straight" brushes. Alternatively, the first and second brushes are "left" brushes.

La torsade "combinée" ou "double torsade" formée par la première âme torsadée relativement à la seconde peut être de même sens que la torsade des première et seconde âmes torsadées.The "combined" or "double twist" twist formed by the first twisted core relative to the second may be in the same sense as the twist of the first and second twisted cores.

Alternativement, la "double torsade" formée par la première âme torsadée relativement à la seconde est de sens inverse au sens de la torsade des première et seconde âmes torsadées.Alternatively, the "double twist" formed by the first twisted core relative to the second is of the opposite direction in the direction of the twist of the first and second twisted cores.

Selon un autre mode de réalisation, la première brosse est une brosse "droite", la seconde brosse étant une brosse "gauche".According to another embodiment, the first brush is a "straight" brush, the second brush being a "left" brush.

Les poils de la première brosse peuvent être de couleur différente des poils de la seconde brosse. Ainsi, les poils de la première brosse peuvent être blancs tandis que les poils de la seconde brosse sont noirs.The bristles of the first brush may be of a different color than the bristles of the second brush. Thus, the bristles of the first brush may be white while the bristles of the second brush are black.

La première âme torsadée est formée à partir de deux branches d'un premier fil de fer, la seconde âme torsadée pouvant être formée à partir de deux branches d'un second fil de fer, identique au premier. Le diamètre du fil de fer formant chacune des deux brosses torsadées peut aller de 0,2 mm à 1,5 mm, et de préférence, de 0,3 mm à 0,8 mm.The first twisted core is formed from two branches of a first wire, the second twisted core being formed from two branches of a second wire, identical to the first. The diameter of the wire forming each of the two twisted brushes can range from 0.2 mm to 1.5 mm, and preferably from 0.3 mm to 0.8 mm.

Alternativement, les premier et second fils de fer sont de diamètres et/ou de nature différents. Ainsi, le premier fil de fer peut être d'un diamètre de 0,45 mm, le second fil de fer étant d'un diamètre voisin de 0,7 mm.Alternatively, the first and second wires are of different diameters and / or nature. Thus, the first wire may have a diameter of 0.45 mm, the second wire being of a diameter of about 0.7 mm.

La première brosse peut comprendre des poils en nombre et/ou de diamètre, et/ou de longueur, et/ou de nature, différents du nombre et/ou du diamètre, et/ou de la longueur, et/ou de la nature des poils de la seconde brosse torsadée.The first brush may include bristles in number and / or diameter, and / or length, and / or nature, different from the number and / or diameter, and / or the length, and / or the nature of the bristles. bristles of the second twisted brush.

Ainsi, les poils de la première brosse peuvent être en polyamide 6-6, 6-10 ou 6-11. Les poils de la seconde brosse peuvent être en élastomère.Thus, the bristles of the first brush may be polyamide 6-6, 6-10 or 6-11. The bristles of the second brush may be elastomeric.

Des ajouts, de type agents bactéricides, charges magnétiques, ou agents de glissement peuvent être ajoutés au matériau thermoplastique formant les poils de manière à en modifier les propriétés mécaniques et/ou chimiques.Additions, such as bactericidal agents, magnetic fillers, or slip agents may be added to the thermoplastic material forming the bristles so as to modify the mechanical and / or chemical properties thereof.

A titre d'exemple, le diamètre des poils de la première brosse peut aller de 0,10 mm à 0,17 mm tandis que les poils de la seconde brosse sont d'un diamètre voisin de 0,25 mm.For example, the diameter of the bristles of the first brush may range from 0.10 mm to 0.17 mm while the bristles of the second brush have a diameter of about 0.25 mm.

A titre d'exemple encore, le nombre de poils de la première brosse peut aller de 10 à 40 par spire tandis qu'il est inférieur à 10 pour la seconde brosse.For example, the number of bristles of the first brush can go from 10 to 40 per turn while it is less than 10 for the second brush.

Alternativement, la première brosse comprend des poils en nombre et/ou de diamètre, et/ou de longueur, et/ou de nature, identiques au nombre et/ou au diamètre, et/ou à la longueur, et/ou à la nature des poils de la seconde brosse torsadée.Alternatively, the first brush comprises bristles in number and / or diameter, and / or length, and / or nature, identical to the number and / or diameter, and / or the length, and / or the nature of the bristles of the second twisted brush.

Ainsi, en jouant de manière combinée ou séparée sur chacun de ces paramètres évoqués précédemment, on multiple les possibilités en termes de maquillage pouvant être obtenu.Thus, by playing combined or separate on each of these parameters mentioned above, multiple possibilities in terms of makeup can be obtained.

On peut multiplier encore les possibilités en jouant sur la forme des extrémités des poils de l'une et/ou l'autre des brosses de départ. Des terminaisons, notamment en forme de boules, de crochets ou autres aspérités peuvent être conférées aux extrémités des poils de l'une et/ou l'autre des brosses, par un traitement notamment thermique, chimique ou mécanique.One can multiply the possibilities by playing on the shape of the ends of the bristles of one and / or the other of the starting brushes. Endings, in particular in the form of balls, hooks or other asperities can be imparted to the ends of the bristles of one and / or the other of the brushes, by a particular thermal, chemical or mechanical treatment.

Selon un autre aspect de l'invention, on réalise également un ensemble pour le conditionnement et l'application d'un produit sur les fibres kératiniques, notamment les cils ou les sourcils, comprenant un récipient contenant le produit, ledit récipient délimitant une ouverture au voisinage de laquelle est disposé un organe d'essorage, ledit ensemble étant équipé d'un applicateur selon l'une quelconque des revendications qui précèdent.According to another aspect of the invention, an assembly is also produced for packaging and applying a product to the keratinous fibers, in particular the eyelashes or the eyebrows, comprising a container containing the product, said container delimiting an opening at the vicinity of which is a wiper member, said assembly being equipped with an applicator according to any one of the preceding claims.

Le produit peut être de consistance liquide à pâteuse, ou solide.The product can be of liquid to pasty consistency, or solid.

Selon encore un autre aspect de l'invention, on réalise également un procédé pour fabriquer un applicateur de produit cosmétique, notamment de mascara comprenant les étapes suivantes :

  • a) former une première brosse constituée d'une première âme torsadée qui, sur une première portion empoilée, emprisonne des poils disposés de manière radiale relativement à l'âme
  • b) former une seconde brosse constituée d'une seconde âme torsadée qui, sur une seconde portion empoilée, emprisonne des poils disposés de manière radiale relativement à l'âme ; et
  • c) enrouler lesdites première et seconde brosses l'une autour de l'autre de sorte que sur au moins une portion empoilée de l'applicateur, les première et seconde âmes soient torsadées l'une relativement à l'autre en s'étendant à distance sensiblement constante l'une de l'autre.
According to yet another aspect of the invention, a method is also provided for manufacturing a cosmetic product applicator, in particular mascara, comprising the following steps:
  • a) forming a first brush consisting of a first twisted core which, on a first empoilated portion, traps bristles arranged radially relative to the core;
  • b) forming a second brush consisting of a second twisted core which, on a second empoilated portion, traps bristles arranged radially relative to the core; and
  • c) winding said first and second brushes around each other so that on at least one empoiled portion of the applicator, the first and second brushes second cores are twisted relative to one another by extending at a substantially constant distance from each other.

Après torsadage, l'applicateur peut faire l'objet d'un certain nombre d'opérations supplémentaires, telles que des opérations de "coupe", notamment au moyen d'une tondeuse, de manière à modifier la forme de la brosse, ou des opérations visant à tordre l'applicateur dans au moins un plan de manière à le rendre courbe.After twisting, the applicator may be the subject of a number of additional operations, such as "cutting" operations, in particular by means of a mower, so as to modify the shape of the brush, or operations to twist the applicator in at least one plane so as to make it curved.

De même, les extrémités libres de l'âme torsadée de chacune des deux brosses peuvent, après torsadage des deux brosses de départ, être réunies au moyen d'un système sous forme d'un bouchon, notamment en matériau thermoplastique, et visant à rendre l'extrémité de l'applicateur moins agressive pour l'oeil.Similarly, the free ends of the twisted core of each of the two brushes may, after twisting of the two starting brushes, be joined by means of a system in the form of a plug, in particular made of thermoplastic material, and intended to render the end of the applicator less aggressive for the eye.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 est relative à un premier mode de réalisation de l'applicateur selon l'invention ;

The invention consists, apart from the arrangements described above, in a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • Figure 1 relates to a first embodiment of the applicator according to the invention;
  • FIG. 2 relates to a second embodiment of the applicator according to the invention;
  • FIG. 3 relates to a third embodiment of the applicator according to the invention;
  • Figures 4A-4D illustrate examples of respective cross sections of the starting brushes, before twisting around each other; and
  • FIG. 5 represents a packaging and applicator assembly using an applicator according to the invention.

-L'applicateur 1 de la figure 1 est réalisé à partir d'une première brosse torsadée 2 et d'une seconde brosse torsadée 6.The applicator 1 of FIG. 1 is made from a first twisted brush 2 and a second twisted brush 6.

La première brosse torsadée 2 comprend une âme torsadée 3 comportant une portion empoilée 4 taillée en forme de cacahuète dans laquelle sont emprisonnés des poils, disposés radialement à l'axe de la brosse. De manière adjacente à la portion empoilée 4, se trouve une portion non empoilée 5. La brosse 2 est de type "brosse droite".The first twisted brush 2 comprises a twisted core 3 having a punched portion 4 cut in the form of peanut in which are trapped bristles, arranged radially to the axis of the brush. Adjacent to the empoilée portion 4, is a non-empoilée portion 5. The brush 2 is "straight brush" type.

La seconde brosse torsadée 6 comprend une âme torsadée 7 comportant une portion empoilée 8 taillée en forme de cacahuète dans laquelle sont emprisonnés des poils disposés radialement à l'axe de la brosse. De manière adjacente à la portion empoilée 8, se trouve une portion non empoilée 9. La brosse 6 est de type "brosse droite".The second twisted brush 6 comprises a twisted core 7 comprising a peanut shaped portion 8 cut in which are trapped hairs arranged radially to the axis of the brush. Adjacent to the empoilated portion 8 is a non-stacked portion 9. The brush 6 is of the "straight brush" type.

Pour obtenir la brosse 1 selon ce mode de réalisation de l'invention, on dispose les brosses 2 et 6 l'une à côté de l'autre, en disposant les extrémités des portions non empoilées 5, 9, des deux brosses 2 et 6 dans un mors, fixe en rotation.In order to obtain the brush 1 according to this embodiment of the invention, the brushes 2 and 6 are arranged next to one another, by arranging the ends of the non-stacked portions 5, 9 of the two brushes 2 and 6. in a jaw, fixed in rotation.

Les extrémités des portions empoilées 4 et 8 des deux brosses sont disposées dans un second mors, entraîné en rotation au moyen d'un moteur tournant dans le sens inverse des aiguilles d'une montre. Les âmes torsadées 3 et 7 des brosses 2 et 6 s'enroulent l'une autour de l'autre pour former une hélice progressant dans le sens inverse de l'hélice formant chacune des âmes torsadées.The ends of the empoilated portions 4 and 8 of the two brushes are arranged in a second jaw, driven in rotation by means of a motor rotating in the opposite direction of clockwise. The twisted cores 3 and 7 of the brushes 2 and 6 wind around each other to form a helix advancing in the opposite direction to the helix each forming twisted cores.

En outre, après torsadage mutuel des brosses 2 et 6, la brosse combinée peut être tondue, au moyen d'un outil de coupe approprié, de manière à en modifier la forme, en fonction d'une esthétique et/ou de propriétés d'application recherchées.In addition, after mutual twisting of the brushes 2 and 6, the combined brush can be mowed, by means of a suitable cutting tool, so as to modify the shape, depending on an aesthetic and / or properties of application sought.

La brosse 1 qui en résulte comprend une portion empoilée 10 et une portion non empoilée 11, adjacente à la portion empoilée. L'extrémité de la portion non empoilée 11 est introduite dans un alésage borgne formé axialement à l'extrémité d'une tige 12, elle même solidaire d'un capuchon 13. L'unité d'application 50 ainsi formée est destinée à équiper un ensemble de conditionnement et d'application qui sera décrit plus en détail par la suite.The resulting brush 1 comprises a potted portion 10 and a non-empoiled portion 11, adjacent to the puckered portion. The end of the unpouched portion 11 is introduced into a blind bore axially formed at the end of a rod 12, itself secured to a cap 13. The application unit 50 thus formed is intended to equip a set of packaging and application that will be described in more detail later.

La portion empoilée 10 de la brosse 1 comprend une pluralité de spires s'imbriquant plus ou moins les unes dans les autres, autorisant des maquillages différents des maquillages pouvant être obtenues avec chacune des brosses 2 et 6 prises séparément.The empoilée portion 10 of the brush 1 comprises a plurality of turns nesting more or less in each other, allowing makeup different makeup can be obtained with each of the brushes 2 and 6 taken separately.

Le mode de réalisation de la figure 2 se distingue du mode de réalisation précédent en ce que la brosse 2 est une brosse de type "gauche", tandis que la brosse 6 est de type "droite". Dans le mode de réalisation précédent, les deux brosses 2 et 6 étaient de type "droite".The embodiment of Figure 2 differs from the previous embodiment in that the brush 2 is a "left" brush, while the brush 6 is of the "right" type. In the previous embodiment, the two brushes 2 and 6 were of the "right" type.

L'arrangement de poils de la brosse 1, obtenue par torsadage des brosses 2 et 6, est distinct de l'arrangement de poils du mode de réalisation précédent. En particulier, le degré d'imbrication des spires, bien que non apparent sur les représentations à caractère purement schématique, est sensiblement plus marqué. A l'application, II en résulte un maquillage différent.The bristle arrangement of the brush 1, obtained by twisting the brushes 2 and 6, is distinct from the bristle arrangement of the previous embodiment. In particular, the degree of nesting of the turns, although not apparent on purely schematic representations, is appreciably more marked. On application, it results in a different makeup.

Le mode de réalisation de la figure 3 se distingue du mode de réalisation de la figure 1 en ce que la portion empoilée 4 de la brosse 2 est en forme de cacahuète tandis que la portion empoilée 8 de la brosse 6 est cylindrique sur sensiblement toute sa longueur et tronconique au voisinage de son extrémité opposée à la queue 9 de la brosse 6.The embodiment of FIG. 3 differs from the embodiment of FIG. 1 in that the emptied portion 4 of the brush 2 is in the form of a peanut while the emptied portion 8 of the brush 6 is cylindrical over substantially all its length and frustoconical near its end opposite the tail 9 of the brush 6.

En torsadant les brosses 2 et 6 de la manière indiquée précédemment en référence aux modes de réalisation des figures 1 et 2, il en résulte un arrangement de poils distinct de celui obtenu précédemment. Un tel arrangement est remarquable notamment par la présence de poils plus courts et de poils plus longs.By twisting the brushes 2 and 6 in the manner indicated above with reference to the embodiments of FIGS. 1 and 2, the result is a hair arrangement distinct from that previously obtained. Such an arrangement is remarkable in particular by the presence of shorter hairs and longer hairs.

Comme il apparaît à la figure 4A, les deux brosses de départ 2 et 6 peuvent être de sections identiques, la densité de poils de la brosse 2 étant plus faible que la densité de poils de la brosse 6.As shown in FIG. 4A, the two starting brushes 2 and 6 may be of identical sections, the bristle density of the brush 2 being smaller than the bristle density of the brush 6.

A la figure 4B, les densités de poils des brosses 2 et 6 sont sensiblement identiques. Toutefois, la brosse 2 est de section plus faible que la brosse 6.In Figure 4B, the bristle densities of the brushes 2 and 6 are substantially identical. However, the brush 2 is of smaller section than the brush 6.

A la figure 4C, la brosse 2 forme un semi-cylindre, avec une face plane, laquelle au moment du torsadage avec la brosse 6, est disposée en regard d'une face plane du triangle formé par la brosse 6.In FIG. 4C, the brush 2 forms a semi-cylinder, with a planar face, which at the time of twisting with the brush 6, is arranged facing a flat face of the triangle formed by the brush 6.

A la figure 4D, la brosse 2 s'étend sur une faible portion angulaire (typiquement de l'ordre de 100°. La brosse 6 s'étend sur une portion angulaire d'environ 240°. Ainsi, en vue de torsader les brosses 2 et 6 l'une autour de l'autre, la brosse 2, de forme complémentaire de la brosse 6, est disposée à l'intérieur du "quartier manquant" de cette dernière.In FIG. 4D, the brush 2 extends over a small angular portion (typically of the order of 100.degree .. The brush 6 extends over an angular portion of approximately 240.degree .. Thus, in order to twist the brushes 2 and 6 one around the other, the brush 2, of complementary shape of the brush 6, is disposed inside the "missing district" of the latter.

D'autres combinaisons encore sont possibles, en fonction de la configuration souhaitée pour l'applicateur. A titre d'exemple supplémentaire, on peut utiliser deux brosses de départ dont la section forme un triangle isocèle, et dont on amène en regard, avant torsadage de l'une par rapport à l'autre, les faces opposées à leurs sommets reliant les deux côtés identiques.Still other combinations are possible, depending on the configuration desired for the applicator. By way of additional example, it is possible to use two starting brushes of which the section forms an isosceles triangle, and of which the opposite faces to their vertices connecting the elements are brought face to face before twisting with respect to one another. two identical sides.

A titre d'exempte encore, la section transversale, par exemple circulaire, de l'une des brosses de départ peut aller en diminuant progressivement depuis la queue jusqu'à l'extrémité libre de sa partie empoilée, tandis que la section de l'autre brosse de départ, également circulaire, va en augmentant progressivement depuis la queue jusqu'à l'extrémité libre de sa partie empoilée.For still further, the cross section, for example circular, of one of the starting brushes can gradually diminish from the tail to the free end of his empoilée part, while the section of the Another starting brush, also circular, is gradually increasing from the tail to the free end of its empoilée part.

A la figure 5, est représenté un ensemble de conditionnement et d'application 100, équipé d'un applicateur 1 tel que décrit précédemment. L'ensemble 100 comporte un récipient 101 contenant une réserve de produit cosmétique tel que du mascara et une unité d'application 50. L'unité d'application 50 comprend une brosse 1, du type brosse torsadée, fixé à une extrémité d'une tige 12, d'axe X. L'autre extrémité de la tige 12 est solidaire d'un élément de préhension 13 qui constitue également un capuchon de fermeture du récipient 101. Le récipient 101 comporte un organe d'essorage 106 constitué ici par un manchon cylindrique dont une extrémité se termine par une lèvre annulaire, souple, 107. En position montée de l'unité d'application 50 sur le récipient 101, la brosse 1 se trouve dans son intégralité entre la lèvre d'essorage 107 et le fond du récipient. D'autres types d'organes d'essorage peuvent être utilisés, par exemple un bloc de mousse à cellules ouvertes ou semi ouvertes, traversé axialement par une fente ou un passage, dont les bords qui la délimitent sont sensiblement jointifs en l'absence de contrainte.In Figure 5, there is shown a set of packaging and application 100, equipped with an applicator 1 as described above. The assembly 100 comprises a container 101 containing a reserve of cosmetic product such as mascara and an application unit 50. The application unit 50 comprises a brush 1, of the twisted brush type, fixed at one end of a rod 12, of axis X. The other end of the rod 12 is integral with a gripping element 13 which also constitutes a closure cap of the container 101. The container 101 comprises a wiper member 106 here constituted by a cylindrical sleeve whose one end terminates in a flexible, annular lip 107. In the mounted position of the application unit 50 on the container 101, the brush 1 is in its entirety between the wiper lip 107 and the bottom of the container. Other types of wiper members may be used, for example an open or semi open cell foam block, traversed axially by a slot or a passage, the edges of which delimit it are substantially contiguous in the absence of constraint.

En vue d'utiliser l'applicateur, l'utilisatrice dévisse le capuchon formé par l'organe de préhension 13, et extrait l'unité d'application 50 du récipient 101. Ce faisant, l'applicateur 1 est amené à passer au travers de l'organe d'essorage 106, de manière à doser la quantité de produit répartie sur les dents ou sur les poils. Le mouvement d'extraction de l'applicateur est de direction sensiblement longitudinale à l'axe X. Après usage, l'utilisatrice remet l'applicateur dans le récipient, en faisant à nouveau passer le dispositif d'application 1 au travers de l'organe d'essorage 106.In order to use the applicator, the user unscrews the cap formed by the gripping member 13, and extracts the application unit 50 from the container 101. In doing so, the applicator 1 is made to pass through of the wiper member 106, so as to dose the amount of product distributed on the teeth or on the bristles. The extraction movement of the applicator is of substantially longitudinal direction to the axis X. After use, the user puts the applicator back into the container, again passing the application device 1 through the wiper member 106.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
