La présente invention concerne un applicateur pour appliquer un produit sur les cils et/ou les sourcils, comportant un organe d'application moulé, et un dispositif de conditionnement et d'application comportant un tel applicateur. The present invention relates to an applicator for applying a product to the eyelashes and / or the eyebrows, comprising a molded application member, and a packaging and applicator device comprising such an applicator.
Un grand nombre d'applicateurs ayant un organe d'application comportant une âme et des dents venues de moulage avec l'âme ont déjà été proposés.  A large number of applicators having an applicator member having a core and teeth integrally molded with the core have already been proposed.
On connaît par la demande EP 1 070 466 un peigne comportant une rangée de dents disposées en quinconce, qui se superposent en partie ou totalement.  EP 1 070 466 discloses a comb comprising a row of teeth arranged in staggered rows, which overlap in part or totally.

Il existe également un besoin pour bénéficier d'un applicateur permettant de réaliser sur les cils ou les sourcils, déjà revêtus de produit ou non, un maquillage par faisceaux.  There is also a need to benefit from an applicator for making eyelashes or eyebrows, already coated with product or not, a make-up by beams.
Résumé  summary
L'invention a pour objet, selon l'un de ses aspects, un applicateur pour appliquer un produit sur les cils et/ou sourcils, comportant un organe d'application moulé comportant :  According to one of its aspects, the subject of the invention is an applicator for applying a product to the eyelashes and / or eyebrows, comprising a molded application member comprising:
une âme ayant un axe longitudinal,  a soul having a longitudinal axis,
une pluralité de rangées longitudinales de dents de section transversale aplatie, se répartissant autour de l'âme et s'étendant chacune selon l'axe longitudinal de l'âme,  a plurality of longitudinal rows of teeth of flattened cross-section, distributed around the core and each extending along the longitudinal axis of the core,
chacune des rangées comportant des dents consécutives disposées en quinconce le long de l'âme et se superposant partiellement à leur base en vue de face, les dents présentant une forme dissymétrique, en vue de face, et les dents présentant également, en vue de face, un bord convexe. each of the rows comprising consecutive teeth arranged staggered along the core and partially overlapping their base in front view, the teeth having an asymmetrical shape, in front view, and the teeth also having, in front view, a convex edge.
L'applicateur constitue une brosse du fait de la pluralité de rangées longitudinales de dents.  The applicator constitutes a brush because of the plurality of longitudinal rows of teeth.
La forme particulière des dents, aplatie, dissymétrique en vue de face et présentant un bord convexe permet une meilleure rétention de produit, et d'avoir une surface de contact relativement importante entre les cils et les dents, ce qui permet de bien charger les cils en produit lors de l'application. L'aplatissement de chacune des dents est sensiblement transversal à l'âme afin de favoriser la séparation de la frange des cils, de donner, lors de l'application ou du peignage, une multitude de faisceaux de cils bien définis et d'éviter la formation de trop gros paquets de cils.  The particular shape of the teeth, flattened, dissymmetrical in front view and having a convex edge allows better product retention, and to have a relatively large contact area between the eyelashes and the teeth, which allows to properly load the eyelashes in product during the application. The flattening of each of the teeth is substantially transverse to the core in order to promote the separation of the eyelash fringe, to give, during the application or combing, a multitude of well-defined eyelash bundles and to avoid formation of too big eyelash packs.
La répartition particulière des dents au sein d'une rangée, à savoir la répartition en quinconce et la superposition partielle, en vue de face, des dents, permet d'augmenter la surface de contact des cils avec le produit présent sur les dents.  The particular distribution of the teeth within a row, namely the staggered distribution and the partial superposition, in front view, of the teeth makes it possible to increase the contact surface of the eyelashes with the product present on the teeth.
L'invention permet d'obtenir, si l'utilisateur le souhaite, un maquillage des cils et/ou des sourcils en faisceaux, c'est-à-dire avec un regroupement de cils en petits paquets distincts, ce qui ordonne les cils et leur donne du volume.  The invention makes it possible to obtain, if the user wishes, eyelash makeup and / or eyebrows in bundles, that is to say with a grouping of eyelashes in small separate packages, which orders the eyelashes and gives them volume.
Une dent est observée en vue de face lorsqu'elle est observée selon l'axe longitudinal de l'âme en projection sur un plan perpendiculaire à l'axe longitudinal de l'âme.  A tooth is observed in front view when it is observed along the longitudinal axis of the soul in projection on a plane perpendicular to the longitudinal axis of the core.
Par « axe longitudinal de l'âme », on désigne la ligne joignant l'ensemble des barycentres des sections transversales de l'âme. L'axe longitudinal peut être un axe central, voire un axe de symétrie pour l'âme, notamment lorsque l'âme présente une section transversale circulaire ou en forme générale de polygone régulier. L'axe longitudinal de l'âme peut être reeti ligne ou courbe et peut être contenu dans un plan, lequel peut être un plan de symétrie pour certaines, voire pour toutes les sections transversales de l'âme. De préférence, l'axe longitudinal de l'âme est rectiligne.  By "longitudinal axis of the soul" is meant the line joining the set of centroids of the cross sections of the soul. The longitudinal axis may be a central axis or an axis of symmetry for the core, especially when the core has a circular cross section or generally polygonal regular shape. The longitudinal axis of the soul can be reeigned line or curve and can be contained in a plane, which can be a plane of symmetry for some or all cross sections of the soul. Preferably, the longitudinal axis of the core is rectilinear.
Par « rangée longitudinale de dents », on désigne une succession de dents dans le sens longitudinal. De préférence, les rangées s'étendent toutes selon des axes longitudinaux respectifs parallèles à l'axe longitudinal de l'âme.  By "longitudinal row of teeth" is meant a succession of teeth in the longitudinal direction. Preferably, the rows all extend along respective longitudinal axes parallel to the longitudinal axis of the core.
Par « dent », on désigne un élément en saillie, individualisable, servant à l'application du produit et à la séparation des cils, et réalisé conformément à l'invention. Par « section transversale aplatie », il faut comprendre que la dent présente, sur au moins une partie de sa hauteur, une section transversale, prise perpendiculairement à sa direction d'élongation, qui est de forme allongée selon un plan d'aplatissement, c'est-à-dire plus large qu'épaisse. De préférence, la dent est aplatie dans une direction perpendiculaire à l'axe longitudinal de l'âme. By "tooth" is meant a protruding, individualizable element for application of the product and the separation of the eyelashes, and produced in accordance with the invention. "Flattened cross-section" means that the tooth has, at least a portion of its height, a cross-section, taken perpendicularly to its direction of elongation, which is elongate in a flattening plane, c that is, wider than thick. Preferably, the tooth is flattened in a direction perpendicular to the longitudinal axis of the core.
Par « disposées en quinconce », il faut comprendre que les bases de deux dents consécutives d'une même rangée ne se superposent pas exactement lorsque l'organe d'application est observé en vue de face, et sont alternativement décalées de part et d'autre d'une ligne médiane.  By "arranged in staggered rows", it should be understood that the bases of two consecutive teeth of the same row are not superimposed exactly when the application member is observed in front view, and are alternately shifted from one side to the other. another of a median line.
Par « une dent présentant, en vue de face, une forme dissymétrique », on désigne une dent réalisée de telle sorte que, lorsqu'elle est observée en vue de face, la dent n'a pas d'axe de symétrie. Une telle dent présente de préférence des bords gauche et droit de formes différentes.  By "a tooth having, in front view, an asymmetrical shape", denotes a tooth made so that, when viewed in front view, the tooth has no axis of symmetry. Such a tooth preferably has left and right edges of different shapes.
Par « bord convexe », on désigne un bord de la dent, lorsqu'elle est observée en vue de face, présentant une courbure arrondie vers l'extérieur de la dent, notamment en forme de portion d'ellipse, de cercle ou de parabole.  By "convex edge" is meant an edge of the tooth, when viewed from the front, having a rounded curvature towards the outside of the tooth, in particular in the form of a portion of an ellipse, a circle or a parabola .
De préférence, l'extension angulaire à la base de la dent, à la jonction avec l'âme, définit l'extension angulaire totale de la dent, autour de l'axe longitudinal de l'âme. De préférence, la dent s'inscrit, en vue de face, dans un rectangle de largeur égale à la plus grande dimension transversale de la dent en vue de face. Preferably, the angular extent at the base of the tooth, at the junction with the core, defines the total angular extent of the tooth, around the longitudinal axis of the core. Preferably, the tooth is registered, in front view, in a rectangle of width equal to the largest transverse dimension of the tooth in front view.
Le nombre de rangées longitudinales peut être supérieur ou égal à 4, mieux à 6. Le nombre de dents d'une rangée de dents est de préférence compris entre 10 et 100, mieux entre 20 et 50.  The number of longitudinal rows may be greater than or equal to 4, more preferably 6. The number of teeth of a row of teeth is preferably between 10 and 100, more preferably between 20 and 50.
La hauteur des dents d'une rangée peut augmenter globalement en éloignement de l'extrémité distale de l'applicateur sur au moins la moitié de la longueur de la rangée de dents, mieux sur la totalité de la longueur de la rangée de dents.  The height of the teeth of a row can increase globally away from the distal end of the applicator over at least half the length of the row of teeth, better over the entire length of the row of teeth.
Par « augmenter globalement », il faut comprendre que le rayon de la surface enveloppe de l'organe d'application, définie par l'extrémité distale des dents, augmente en éloignement de l'extrémité distale de l'applicateur, de façon continue ou par paliers.  By "increase overall", it should be understood that the radius of the envelope surface of the applicator member, defined by the distal end of the teeth, increases away from the distal end of the applicator, continuously or in steps.
En variante, la hauteur des dents d'une rangée peut diminuer globalement en éloigneraent de l'extrémité distale de l'applicateur sur au moins la moitié de la longueur de la rangée de dents, mieux sur la totalité de la longueur de la rangée de dents.

Alternatively, the height of the teeth of a row may decrease overall away from the distal end of the applicator over at least half the length of the row of teeth, better over the entire length of the row of teeth. teeth. Each tooth in each row may taper upwards at least over a portion of the tooth's height, better over the entire height of the tooth.
Chaque dent de chacune des rangées peut s'amincir vers le bord situé du côté extérieur desdites rangées de dents. Le bord situé du côté extérieur desdites rangées de dents est de préférence le bord convexe.  Each tooth of each of the rows may tap toward the edge on the outer side of said rows of teeth. The edge on the outer side of said rows of teeth is preferably the convex edge.
Chaque dent de chacune des rangées peut avoir une section transversale aplatie sur au moins la moitié de sa hauteur, mieux la totalité de sa hauteur ou éventuellement seulement au-dessus d'un rétrécissement de sa section à proximité de la base de la dent.  Each tooth of each of the rows may have a flattened cross section over at least half of its height, better all of its height or possibly only above a narrowing of its section near the base of the tooth.
Le bord convexe peut s'étendre sur au moins la moitié de la hauteur de la dent, mieux sur toute la hauteur de la dent, à savoir de la base à l'extrémité libre de la dent.  The convex edge can extend over at least half the height of the tooth, better over the entire height of the tooth, namely from the base to the free end of the tooth.
Chaque dent de chacune des rangées présente, de préférence, un bord rectiligne situé, de préférence, du côté intérieur de la rangée de dents. Les dents s'amincissent notamment du bord rectiligne vers le bord situé du côté extérieur des rangées de dents, notamment le bord convexe.  Each tooth of each of the rows preferably has a straight edge preferably located on the inside of the row of teeth. The teeth thin in particular the rectilinear edge to the edge located on the outer side of the rows of teeth, including the convex edge.
En variante, chaque dent de chacune des rangées présente un bord concave situé, de préférence, du côté intérieur de la rangée de dents. Les dents s'amincissent notamment du bord rectiligne vers le bord situé du côté extérieur des rangées de dents, notamment le bord convexe.  Alternatively, each tooth of each row has a concave edge preferably located on the inside of the row of teeth. The teeth thin in particular the rectilinear edge to the edge located on the outer side of the rows of teeth, including the convex edge.
Le bord convexe peut être un bord anguleux de chaque dent et peut constituer, en section transversale de la dent, une arête.  The convex edge may be an angular edge of each tooth and may constitute, in cross section of the tooth, an edge.
Le bord convexe est, de préférence, orienté vers l'extérieur de la rangée de dents.  The convex edge is preferably oriented towards the outside of the row of teeth.

Le rapport m/n des hauteurs entre deux dents adjacentes peut être compris entre 0,1 et 0,9, m étant la hauteur de la dent la plus courte des deux dents adjacentes et n étant la hauteur de la dent la plus longue. Les dents du premier alignement sont alors plus grandes ou plus petites que les dents du deuxième alignement.  The ratio m / n of the heights between two adjacent teeth can be between 0.1 and 0.9, where m is the height of the shorter tooth of the two adjacent teeth and n is the height of the longest tooth. The teeth of the first alignment are then larger or smaller than the teeth of the second alignment.
En variante, la hauteur des dents peut varier de façon alternée par paquets de dents, chaque paquet étant notamment constitué de deux dents de même hauteur.  Alternatively, the height of the teeth may vary alternately in packets of teeth, each package being in particular constituted by two teeth of the same height.

Comme illustré aux figures 2 et 3, l'âme est de forme allongée selon un axe longitudinal X, qui peut être rectiligne ou courbe, étant de préférence rectiligne.  As illustrated in Figures 2 and 3, the core is of elongated shape along a longitudinal axis X, which may be straight or curved, preferably being rectilinear.
L'âme 10 peut être, comme illustré sur la figure 10A, sur la majorité de sa longueur, de section transversale polygonale, notamment hexagonale, les côtés de l'âme 10 définissant des faces longitudinales 40. Ces dernières peuvent être toutes pourvues de dents 20. Les faces 40 sont de préférence planes, comme dans l'exemple illustré, mais pourraient être courbes en variante. Dans une variante non illustrée, seule une partie des faces 40 de l'âme 10 porte des dents 20.  The core 10 may be, as illustrated in FIG. 10A, over most of its length, of polygonal cross-section, in particular hexagonal, the sides of the core 10 defining longitudinal faces 40. The latter may all be provided with teeth. 20. The faces 40 are preferably flat, as in the illustrated example, but could be alternately curved. In a variant not illustrated, only a portion of the faces 40 of the core 10 carries teeth 20.
L'âme 10 peut, en variante et comme illustré sur la figure 10B, être, sur la majorité de sa longueur, de section transversale circulaire.  The core 10 may alternatively and as illustrated in FIG. 10B be, for the majority of its length, of circular cross section.

Dents  teeth
L'organe d'application 8 comporte des dents 20, qui s'étendent chacune à partir de l'âme 10 vers l'extérieur, en direction d'une extrémité libre 26.  The applicator member 8 comprises teeth 20, which each extend from the core 10 towards the outside, in the direction of a free end 26.
Forme des dents  Tooth shape
Comme illustré sur les figures, les dents d'au moins une rangée de dents 20, et mieux, comme illustré sur la figure 2, la totalité des dents 20, présente en vue de face un bord convexe 22. Ce dernier peut être, comme illustré sur la figure 4, une portion de courbe, notamment de cercle ou de parabole, et de préférence une portion d'ellipse.  As illustrated in the figures, the teeth of at least one row of teeth 20, and better, as illustrated in FIG. 2, all of the teeth 20, present in front view a convex edge 22. The latter can be, as illustrated in FIG. 4, a portion of a curve, in particular of a circle or of a parabola, and preferably an ellipse portion.

Chaque dent 20 peut s'amincir, comme illustré sur la figure 5, vers le bord convexe 22. En section transversale, l'angle au sommet //, formé entre les faces principales 31 et 32 opposées de la dent 20, peut être inférieur ou égal à 40°, mieux inférieur ou égal à 15°. Cet amincissement permet une déviation des cils dès leur contact avec l'applicateur 1. Comme illustré à la figure 4, chaque dent 20 peut s'amincir en vue de face vers le haut sur au moins une partie B de sa hauteur, mieux au moins la moitié de sa hauteur. La partie B peut s'étendre à partir de la base 25. La grande dimension de la base 25 est comprise par exemple entre 0,3 mm et 3 mm. De préférence, l'extrémité libre 26 de chaque dent est, en vue de face, comme illustré sur la figure 4, effilée, formant notamment une pointe qui facilite la pénétration dans les cils et la séparation de ces derniers. Each tooth 20 may thin, as shown in FIG. 5, towards the convex edge 22. In cross-section, the angle at the apex, formed between the main faces 31 and 32 opposite the tooth 20, may be less than or equal to 40 °, better less than or equal to 15 °. This thinning allows a deviation of the eyelashes from their contact with the applicator 1. As illustrated in Figure 4, each tooth 20 may thin in front view upward on at least a portion B of its height, better at least half of its height. Part B may extend from the base 25. The large dimension of the base 25 is for example between 0.3 mm and 3 mm. Preferably, the free end 26 of each tooth is, in front view, as shown in Figure 4, tapered, including a tip which facilitates the penetration into the eyelashes and the separation thereof.
Comme illustré sur la figure 5, chaque dent 20 est de section transversale aplatie sur une partie de sa hauteur, mieux sur plus de la moitié de sa hauteur, encore mieux sur la totalité de sa hauteur. Les dents 20 ont de préférence leur plan d'aplatissement Z orienté sensiblement perpendiculairement à l'âme 10. Le plan d'aplatissement Z est de préférence un plan médian de symétrie pour la dent 20.  As illustrated in Figure 5, each tooth 20 is of flattened cross section over part of its height, better over more than half of its height, even better over its entire height. The teeth 20 preferably have their flattening plane Z oriented substantially perpendicularly to the core 10. The plane of flattening Z is preferably a median plane of symmetry for the tooth 20.
Comme illustré sur les figures 4 et 5, chaque dent 20 peut comporter, en vue de face, un bord rectiligne 24, notamment radial par rapport à l'axe longitudinal X de l'âme 10, s 'étendant sur plus de la moitié de la hauteur h de la dent 20, de préférence sur la totalité de la hauteur h de la dent 20.  As illustrated in FIGS. 4 and 5, each tooth 20 may comprise, in front view, a rectilinear edge 24, in particular radial with respect to the longitudinal axis X of the core 10, extending over more than half of the height h of the tooth 20, preferably over the entire height h of the tooth 20.
De préférence, comme illustré sur la figure 4, la dent 20 s'inscrit, en vue de face, dans un rectangle de largeur sensiblement égale à la plus grande dimension transversale L de la dent 20 en vue de face.  Preferably, as illustrated in Figure 4, the tooth 20 is, in front view, in a rectangle of width substantially equal to the largest transverse dimension L of the tooth 20 in front view.
De préférence, chaque dent 20 a une étendue angulaire /qui est égale à l'étendue angulaire de la base de la dent 25.  Preferably, each tooth 20 has an angular extent / which is equal to the angular extent of the base of the tooth 25.
Chaque dent 20 comporte de préférence, comme illustré notamment à la figure 5, une face plane 24 qui définit ce bord rectiligne. La face plane 24 est à l'opposé du bord convexe 22 de la dent 20. De préférence, chaque dent 20 s'amincit de la face plane 24 vers le bord convexe 22. De préférence, ce dernier définit une arête.  Each tooth 20 preferably comprises, as illustrated in particular in Figure 5, a flat face 24 which defines the straight edge. The flat face 24 is opposite the convex edge 22 of the tooth 20. Preferably, each tooth 20 tapers from the flat face 24 to the convex edge 22. Preferably, the latter defines an edge.
Chaque dent 20 peut présenter deux faces principales longitudinales opposées 31 et 32 qui sont planes ou incurvées, étant concaves ou de préférence, comme illustré sur la figure 5, convexes vers l'extérieur. Comme illustré sur la figure 5, les faces 31 et 32 sont de préférence des portions d'ellipsoïde. Les faces 31 et 32 sont de préférence, comme illustré à la figure 5, de même forme. Dans les exemples illustrés, les faces 31 et 32 relient la face plane 24 au bord convexe 22. Each tooth 20 may have two opposite longitudinal main faces 31 and 32 which are flat or curved, being concave or preferably, as shown in Figure 5, convex outwardly. As illustrated in FIG. 5, the faces 31 and 32 are preferably ellipsoid portions. The faces 31 and 32 are preferably, as illustrated in FIG. 5, of the same shape. In the illustrated examples, the faces 31 and 32 connect the plane face 24 to the convex edge 22.
La. plus grande largeur L de chaque dent 20, définie comme la plus grande dimension de la dent 20 selon le plan d'aplatissement Z, peut être comprise entre 0,3 mm et 3 mm, mieux entre 0,5 mm et 1 ,5 mm. Cette plus grande largeur L est de préférence mesurée à la base des dents 20, comme illustré à la figure 4.  The largest width L of each tooth 20, defined as the largest dimension of the tooth 20 in the plane of flattening Z, may be between 0.3 mm and 3 mm, more preferably between 0.5 mm and 1 mm. 5 mm. This larger width L is preferably measured at the base of the teeth 20, as shown in FIG. 4.
La hauteur h de chaque dent 20 peut être comprise entre 0,5 mm et 1 cm, mieux entre 1 mm et 5 mm. L'épaisseur maximale / de chaque dent 20 peut être comprise entre 0,2 mm et 1 mm, mieux entre 0,4 mm et 1,5 mm. Cette épaisseur maximale / peut être mesurée à la base des dents 20. L'épaisseur de chaque dent 20 à son extrémité libre 26 peut être inférieure ou égale à 0,5 mm.  The height h of each tooth 20 may be between 0.5 mm and 1 cm, better between 1 mm and 5 mm. The maximum thickness of each tooth 20 may be between 0.2 mm and 1 mm, more preferably between 0.4 mm and 1.5 mm. This maximum thickness / can be measured at the base of the teeth 20. The thickness of each tooth 20 at its free end 26 may be less than or equal to 0.5 mm.
De préférence, les dents 20 sont pleines. En variante, les dents 20 peuvent présenter un orifice traversant ou non.  Preferably, the teeth 20 are full. Alternatively, the teeth 20 may have a through hole or not.
Les dents 20 peuvent s'étendre à partir d'une unique base 25 de contour fermé. Teeth 20 may extend from a single closed contour base.
L'extension circonférentielle γ des dents sur l'âme peut-être inférieure ou égale à 180°, mieux inférieure ou égale à 90°. The circumferential extension γ of the teeth on the core may be less than or equal to 180 °, better than or equal to 90 °.
De préférence, comme illustré sur la figure 4A, les dents 20 s'effilent à leurs extrémités distales 26 pour former une pointe. De préférence, les tangentes // et à la surface de la dent 20, en vue de face, prises à une hauteur h ' égale à 90% de la hauteur h de la dent 20, forment un angle β inférieur ou égal à 90° Preferably, as shown in FIG. 4A, the teeth 20 taper at their distal ends 26 to form a tip. Preferably, the tangents / / and the surface of the tooth 20, in front view, taken at a height h 'equal to 90% of the height h of the tooth 20, form an angle β less than or equal to 90 °
Le rapport L/h de la plus grande largeur L de la dent 20 sur la hauteur h de la dent 20 doit être compris entre 0,5 et 2.  The L / h ratio of the greatest width L of the tooth 20 over the height h of the tooth 20 must be between 0.5 and 2.
Les dents 20 sont de préférence réalisées dans le même matériau qu'au moins une partie de l'âme 10, mieux toute l'âme 10. Les dents 20 sont de préférence réalisées d'un seul tenant avec l'âme 10 par moulage de matière thermoplastique.  The teeth 20 are preferably made of the same material as at least a part of the core 10, better the entire core 10. The teeth 20 are preferably made in one piece with the core 10 by molding of thermoplastic material.
En variante, chaque dent 20 ne s'amincit pas sur la totalité de sa hauteur. Chaque dent 20 peut alors présenter, sur une partie A de sa hauteur, une zone de largeur constante ou croissante vers le haut. Cette partie A a une hauteur qui est de préférence inférieure à la moitié de la hauteur h de la dent 20. Comme illustré à la figure 7B, le plan d'aplatissement Z peut être orienté obliquement par rapport à l'axe longitudinal X de l 'âme 10 selon un angle Θ compris entre 45° et 90°. Alternatively, each tooth 20 does not thin over its entire height. Each tooth 20 may then present, on a part A of its height, a zone of constant width or increasing upwards. This part A has a height which is preferably less than half the height h of the tooth 20. As illustrated in FIG. 7B, the plane of flattening Z can be oriented obliquely with respect to the longitudinal axis X of the core 10 at an angle Θ of between 45 ° and 90 °.
Dans une variante non illustrée, l'axe médian de la face plane 24 ne s'étend pas perpendiculairement à l'axe X mais obliquement par rapport à celui-ci, vers l'avant, c'est-à-dire vers l'extrémité distale de Tapplicateur, ou vers Γ arrière.  In a non-illustrated variant, the median axis of the plane face 24 does not extend perpendicular to the axis X but obliquely with respect thereto, towards the front, that is to say towards the distal end of the applicator, or backwards.
Les dents 20 et l'âme 10 peuvent être réalisées dans des matériaux différents, le cas échéant, par bi -injection. Les dents 20 sont par exemple moulées au travers d'ouvertures de l'âme 10, Les dents 20 peuvent être réalisées dans un matériau plus mou que l'âme ou, en variante, plus dur que l'âme.  The teeth 20 and the core 10 may be made of different materials, where appropriate, by bi-injection. The teeth 20 are for example molded through openings of the core 10, the teeth 20 may be made of a material softer than the core or, alternatively, harder than the core.
Agencement de deux dents adjacentes successives  Arrangement of two successive adjacent teeth
Comme illustré sur les figures, l'âme 10 peut comporter à sa surface au moins une rangée de paires 15 de dents adjacentes, mieux, comme illustré à la figure 2, une pluralité de rangées de paires 15 de dents adjacentes, telles que les dents 20 décrites ci-dessus.  As illustrated in the figures, the core 10 may have at least one row of adjacent pairs of teeth on its surface, better, as illustrated in FIG. 2, a plurality of rows of pairs of adjacent teeth, such as the teeth. 20 described above.
Comme on peut le voir à la figure 8, les dents 20a et 20b de chaque paire 15 de dents adjacentes sont décalées axialement d'une distance D, cette dernière étant la distance entre les pians d'aplatissement Z des deux dents 20a et 20b. La distance D peut être comprise entre 0,5 mm et 3 mm.  As can be seen in FIG. 8, the teeth 20a and 20b of each pair of adjacent teeth are axially offset by a distance D, the latter being the distance between the flattening jaws Z of the two teeth 20a and 20b. The distance D can be between 0.5 mm and 3 mm.
Comme visible aux figures 7A et 9, les dents 20a et 20b adjacentes sont décalées autour de l'axe longitudinal X de l'âme 10. L'écart angulaire a entre les deux dents 20a et 20b, défini, en vue de face, par l'angle a entre 3e rayon de l'âme 10 passant par le milieu Xa de l'arc d'intersection des dents 20a avec l'âme 10 et le rayon de l'âme 10 passant par le milieu Xb de l'arc d'intersection des dents 20b avec l'âme 10, est de préférence compris entre 5° et 60°. As can be seen in FIGS. 7A and 9, the adjacent teeth 20a and 20b are offset around the longitudinal axis X of the core 10. The angular difference α between the two teeth 20a and 20b, defined, in front view, by the angle α between the third radius of the core 10 passing through the middle X a of the arc of intersection of the teeth 20a with the core 10 and the radius of the core 10 passing through the middle X b of the the intersection arc of the teeth 20b with the core 10 is preferably between 5 ° and 60 °.
Les deux dents 20a et 20b adjacentes peuvent être de même hauteur, comme illustré à la figure 12, ou de hauteurs différentes, comme illustré notamment à la figure 10 A. On voit sur cette dernière figure que chaque dent 20a est légèrement plus haute que chaque dent adjacente 20b, qui se situe devant elle, c'est-à-dire qui est plus proche de l'extrémité distale 42 de l'applicateur.  The two adjacent teeth 20a and 20b may be of the same height, as illustrated in FIG. 12, or of different heights, as illustrated in particular in FIG. 10A. It can be seen in this last figure that each tooth 20a is slightly higher than each adjacent tooth 20b, which is in front of it, that is to say which is closer to the distal end 42 of the applicator.
Comme illustré à la figure 9, le bord convexe 22 des dents 20a peut être orienté en vue de face vers la droite alors que le bord convexe 22 des dents 20b peut être orienté vers la gauche, ou inversement. Cette orientation opposée des bords convexes 22 permet à la brosse de pouvoir être utilisée dans un sens comme dans l'autre, tout en produisant le même effet. As illustrated in FIG. 9, the convex edge 22 of the teeth 20a can be oriented in a front view to the right while the convex edge 22 of the teeth 20b can be oriented to the left, or vice versa. This opposite orientation of the convex edges 22 allows the brush to be used in one direction as in the other, while producing the same effect.

L'écart angulaire a entre les deux dents 20a et 20b est inférieur aux étendues angulaires γ occupées par chacune des dents 20a et 20b, ces étendues angulaires étant définies par l'angle occupé par les dents à leur base. Comme illustré à la figure 9, l'angle de recouvrement φ défini en vue de face comme l'angle qu'occupe la surface de superposition Sab entre les deux dents 20a et 20b autour de l'axe longitudinal X, c'est-à-dire γ-α, peut être inférieur ou égal à 5°. The adjacent teeth 20a and 20b can be superimposed at least partially, in particular at their base 25, and on at least a part of the height h of the two teeth 20a and 20b, better as can be seen in FIG. 9, over the entire height of at least one of the teeth 20a or 20b. The angular gap α between the two teeth 20a and 20b is smaller than the angular extent γ occupied by each of the teeth 20a and 20b, these angular extents being defined by the angle occupied by the teeth at their base. As illustrated in FIG. 9, the angle of overlap φ defined in front view as the angle occupied by the superposition surface S ab between the two teeth 20a and 20b around the longitudinal axis X, is ie γ-α, may be less than or equal to 5 °.
Chaque dent 20a peut être, comme illustré aux figures 10A, 10B et 11, plus grande que chaque dent 20b adjacente, ou inversement. Le rapport m/n des hauteurs est de préférence compris entre 0,1 et 0,9, m étant la hauteur de la petite dent et n étant la hauteur de la grande dent.  Each tooth 20a may be, as illustrated in Figures 10A, 10B and 11, larger than each adjacent tooth 20b, or vice versa. The ratio m / n heights is preferably between 0.1 and 0.9, where m is the height of the small tooth and n is the height of the large tooth.
Les dents 20a et 20b peuvent être, comme illustré aux figures 9 et 12, de même hauteur, la première dent 20a étant de préférence en vue de face l'image de la deuxième dent 20b par rapport à un plan de symétrie M parallèle à l'axe longitudinal X de l'âme 10.  The teeth 20a and 20b can be, as illustrated in FIGS. 9 and 12, of the same height, the first tooth 20a being preferably in front view the image of the second tooth 20b with respect to a plane of symmetry M parallel to the longitudinal axis X of the core 10.

Les rangées 50 s'étendent préférentiellement selon 3 'axe longitudinal X de l'âme 10.  As illustrated in the figures, the applicator member 8 can comprise at least one row 50 of pairs of teeth 15, better a plurality of rows 50 of pairs of teeth 15, the pairs of teeth 15 having teeth 20a and 20b such as as previously described. The rows 50 extend preferably along the longitudinal axis X of the core 10.
L'organe d'application 8 peut comporter au moins deux rangées 50 de paires de dents 15, mieux au moins quatre rangées 50, encore mieux au moins six rangées 50 disposées autour de l'axe longitudinal X de P 10.  The applicator member 8 may comprise at least two rows 50 of pairs of teeth 15, better still at least four rows 50, and still more preferably at least six rows 50 arranged around the longitudinal axis X of P 10.
Toutes les rangées 50 de l'organe d'application 8 sont de préférence identiques. Les dents de chacune des rangées 50 ont de préférence même abscisse, le long de l'axe longitudinal X, que les dents de même rang des rangées 50 adjacentes. Ainsi, les dents de même rang paraissent alignées quand l'organe d'application est observé de côté. Les rangées 50 présentent de préférence entre elles un écartement régulier autour de l'axe longitudinal X de l'âme 10. All the rows 50 of the applicator member 8 are preferably identical. The teeth of each of the rows 50 preferably have the same abscissa, along the longitudinal axis X, as the teeth of the same rank of the adjacent rows 50. Thus, the teeth of the same rank appear aligned when the applicator member is viewed from the side. The rows 50 preferably have between them a regular spacing around the longitudinal axis X of the core 10.
Comme illustré sur les figures 10A à 10B, l'écart angulaire ω entre deux rangées 50 consécutives, lorsque l'on se déplace autour de l'axe longitudinal X de l'âme 10, est de préférence constant, l'écart angulaire ω étant défini en vue de face par l'angle entre les rayons de l'âme 10 qui passent par les barycentres desdites rangées. L'écart angulaire ω est de préférence compris entre 15° et 95°, mieux entre 45° et 75°, encore mieux est égal à 60°.  As illustrated in FIGS. 10A to 10B, the angular difference ω between two consecutive rows 50, as one moves around the longitudinal axis X of the core 10, is preferably constant, the angular difference ω being defined in front view by the angle between the spokes of the soul 10 which pass through the centers of said rows. The angular difference ω is preferably between 15 ° and 95 °, more preferably between 45 ° and 75 °, more preferably equal to 60 °.
De telles rangées 50 peuvent être qualifiées de « rangées doubles » du fait de la présence de deux alignements distincts 50a et 50b de dents respectives 20a et 20b, les dents 20a, respectivement 20b, étant alignées entre elles, lorsque l'organe d'application 8 est observée en vue de face selon son axe longitudinal X.  Such rows 50 may be described as "double rows" because of the presence of two distinct alignments 50a and 50b of respective teeth 20a and 20b, the teeth 20a and 20b respectively being aligned with one another when the applicator member 8 is seen in front view along its longitudinal axis X.
Comme illustré à la figure 13, la distance axiale g entre deux paires de dents 15 consécutives de la rangée 50 est de préférence constante et comprise entre 0,8 mm et 4 mm, la distance axiale q étant définie par la distance en vue de côté entre les plans d'aplatissement Z des premières dents 20a au sein de l'alignement 50a de dents 20a.  As illustrated in FIG. 13, the axial distance g between two pairs of consecutive teeth 15 of row 50 is preferably constant and between 0.8 mm and 4 mm, the axial distance q being defined by the distance in side view. between the flattening planes Z of the first teeth 20a within the alignment 50a of teeth 20a.
Lorsque l'âme est de section hexagonale, comme illustré à la figure 10A, l'organe d'application 8 comporte de préférence six rangées doubles 50, chaque rangée double 50 ayant son axe longitudinal disposé sur une arête de l'âme 10. Les dents 20a s'étendent sur la quasi-totalité de leur base 25 sur une des faces planes 40 de l'âme 10, attenante à ladite arête. Les dents 20b s'étendent sur la quasi-totalité de leur base 25 sur l'autre face plane 40 attenante à ladite arête.  When the core is of hexagonal section, as illustrated in FIG. 10A, the applicator member 8 preferably comprises six double rows 50, each double row 50 having its longitudinal axis disposed on an edge of the core 10. teeth 20a extend over almost all of their base 25 on one of the flat faces 40 of the core 10, adjacent to said edge. The teeth 20b extend over almost all of their base 25 on the other flat face 40 adjacent to said edge.
La surface enveloppe S de l'organe d'application 8, définie par l'extrémité libre 26 des dents 20, peut être une surface de révolution, notamment conique.  The envelope surface S of the applicator member 8, defined by the free end 26 of the teeth 20, may be a surface of revolution, in particular a conical surface.

De préférence, comme illustré à la figure 13, chaque alignement 50a et 50b comporte des grandes dents qui alternent avec de petites dents, de moindre hauteur que les grandes dents. Les dents de rang pair de chaque alignement 50a et 50b sont par exemple plus petites que les dents de rang impair, ou inversement. Le rapport des hauteurs m/n est de préférence compris entre 0,6 et 0,9, m étant la hauteur de la petite dent et /; étant la hauteur de la grande dent. Chaque dent de rang impair, du premier alignement 50a, est de préférence de même hauteur h que la dent de rang pair, adjacente, du deuxième alignement 50b. Chaque dent de rang pair du premier alignement 50a est de préférence de même hauteur h que la dent de rang impair, adjacente, du deuxième alignement 50b. Les dents 20a et 20b sont alors de même taille par paire de dents adjacentes de la rangée double 50. Preferably, as illustrated in Figure 13, each alignment 50a and 50b has large teeth that alternate with small teeth, lower in height than large teeth. The teeth of even rank of each alignment 50a and 50b are for example smaller than the teeth of odd rank, or vice versa. The ratio of the heights m / n is preferably between 0.6 and 0.9, m being the height of the small tooth and /; being the height of the big tooth. Each odd-ranked tooth of the first alignment 50a is preferably of the same height h as the adjacent even rank tooth of the second alignment 50b. Each even rank tooth of the first alignment 50a is preferably of the same height h as the odd, adjacent tooth of the second alignment 50b.

De préférence, pour chaque rangée double 50, le premier alignement 50a se superpose, notamment à sa base en 54, comme illustré sur les figures 10A et 9, avec le deuxième alignement 50b d'une rangée double 50 adjacente. Cette superposition peut n'être que de faible étendue angulaire. L'angle de recouvrement^, défini comme, en vue de face, l'angle qu'occupe-la surface de superposition ¾, entre les deux dents 20a et 20b des deux alignements 50a et 50b par rapport à l'axe longitudinal X, peut être inférieur ou égal à 45°.  Preferably, for each double row 50, the first alignment 50a is superimposed, in particular at its base at 54, as illustrated in FIGS. 10A and 9, with the second alignment 50b of an adjacent double row 50. This superposition can be only of small angular extent. The angle of overlap, defined as, in front view, the angle occupied by the superposition surface ¾, between the two teeth 20a and 20b of the two alignments 50a and 50b with respect to the longitudinal axis X, may be less than or equal to 45 °.
En variante, en vue de face, les dents de rangées 50 voisines ne se superposent pas.  Alternatively, in front view, the teeth of rows 50 neighbors are not superimposed.
L'écart angulaire ω entre deux rangées 50 consécutives, lorsque l'on se déplace autour de l'axe longitudinal X de l'organe d'application 8, peut aussi, dans une variante non illustrée, varier autour de l'âme 10.  The angular difference ω between two consecutive rows 50, when one moves around the longitudinal axis X of the applicator member 8, may also, in a variant not shown, vary around the core 10.
Comme illustré à la figure 11, les paires de dents 15 peuvent avoir, les unes par rapport aux autres, une hauteur croissante lorsque l'on se déplace le long de l'axe longitudinal de l'âme sur la quasi-totalité de la longueur qmax de la rangée 50. Les dents 20a et 20b de chaque alignement 50a et 50b peuvent être de hauteur h croissante en s'éloignant de l'extrémité distale 42 de l'organe d'application 8, les dents 20a du premier alignement 50a étant plus petites que les dents 20b du deuxième alignement 50b de même rang, ou inversement. As illustrated in FIG. 11, the pairs of teeth 15 may have, relative to each other, an increasing height when moving along the longitudinal axis of the core over almost the entire length q max of the row 50. The teeth 20a and 20b of each alignment 50a and 50b may be of increasing height h away from the distal end 42 of the applicator member 8, the teeth 20a of the first alignment 50a being smaller than the teeth 20b of the second alignment 50b of the same rank, or conversely.
La distance D entre deux dents adjacentes 20a et 20b d'une rangée 50 peut être variable sur au moins la moitié de la longueur qmax de la rangée 50. The distance D between two adjacent teeth 20a and 20b of a row 50 may be variable over at least half the length q max of the row 50.
Les rangées 50 de l'organe d'application 8 peuvent être différentes les unes des autres. La forme des dents 20a et 20b de deux rangées 50 voisines peut varier sensiblement, notamment par la hauteur h des dents 20a et 20b correspondantes. Les dents d'une rangée 50 peuvent être toutes plus grandes que les dents de même rang d'une des rangées 50 adjacentes. En variante, les dents 20a et 20b de même rang de rangées 50 voisines ne sont pas alignées autour de l'axe longitudinal X lorsque l'organe d'application est observé perpendiculairement à l'axe longitudinal de l'âme. Les dents 20a et 20b de même rang de rangées 50 voisines peuvent être décalées selon l'axe longitudinal X. The rows 50 of the applicator member 8 may be different from each other. The shape of the teeth 20a and 20b of two adjacent rows 50 may vary substantially, in particular by the height h of the teeth 20a and 20b corresponding. The teeth of a row 50 may all be larger than the teeth of the same rank of one of the adjacent rows 50. Alternatively, the teeth 20a and 20b of the same rank of neighboring rows 50 are not aligned about the longitudinal axis X when the applicator member is observed perpendicular to the longitudinal axis of the core. The teeth 20a and 20b of the same rank of neighboring rows 50 may be offset along the longitudinal axis X.
En variante, les dents peuvent former des paquets de dents adjacentes de même hauteur, la hauteur des paquets adjacents de dents alternant selon l'axe longitudinal X. Les paquets peuvent être formés chacun d'au moins trois dents.  Alternatively, the teeth may form bundles of adjacent teeth of the same height, the height of the adjacent bundles of teeth alternating along the longitudinal axis X.
