Description

L'invention est relative à une brosse destinée à l'application d'un produit cosmétique, en particulier sur les cils ou les cheveux, du genre de celles qui comprennent une multitude de poils implantés transversalement dans une âme, en particulier formée par des spires d'un fil métallique torsadé, spires entre lesquelles les poils sont coincés, ces poils étant formés par un mélange de poils choisis parmi au moins deux groupes, à savoir un premier groupe constitué de poils de section relativement faible, en particulier inscrite dans un cercle de diamètre compris entre 6 et 13 centièmes de millimètre et un deuxième groupe de poils de section plus importante, en particulier inscrite dans un cercle de diamètre supérieur à 13 centièmes de millimètre et généralement inférieur à 30 centièmes de millimètre, les poils de faible section ayant une longueur suivant la direction radiale supérieure à celle des poils de forte section, sur une partie au moins de la brosse.The invention relates to a brush intended for the application of a cosmetic product, in particular to the eyelashes or the hair, of the kind which includes a multitude of bristles implanted transversely in a core, in particular formed by turns. of a twisted metal wire, turns between which the hairs are trapped, these hairs being formed by a mixture of hairs chosen from at least two groups, namely a first group consisting of hairs of relatively small section, in particular inscribed in a circle with a diameter between 6 and 13 hundredths of a millimeter and a second group of bristles with a larger section, in particular inscribed in a circle with a diameter greater than 13 hundredths of a millimeter and generally less than 30 hundredths of a millimeter, the bristles of small section having a length in the radial direction greater than that of bristles of large section, on at least part of the brush .

FR-A-2 637 472 montre une brosse de ce type permettant à la fois de prélever une quantité appropriée de produit pour le déposer sur les cils, et de peigner et lisser ces derniers.FR-A-2 637 472 shows a brush of this type making it possible both to take an appropriate quantity of product to deposit it on the eyelashes, and to comb and smooth them.

Bien que de tels types de brosses soient, dans l'ensemble, satisfaisants, ils ne permettent pas de réaliser des maquillages véritablement différents de ceux obtenus avec des brosses traditionnelles.Although such types of brushes are, on the whole, satisfactory, they do not make it possible to make genuinely different make-ups from those obtained with traditional brushes.

L'invention a pour but, surtout, de fournir une brosse permettant d'obtenir un maquillage chargé, séparé, différent de ceux obtenus jusqu'à présent.The object of the invention is, above all, to provide a brush making it possible to obtain a charged, separate make-up, different from that obtained hitherto.

L'invention a également pour but de fournir une brosse qui reste d'un prix abordable et de proposer un procédé simple pour la réalisation d'une telle brosse.The invention also aims to provide a brush which remains affordable and to provide a simple method for making such a brush.

Selon l'invention, une brosse destinée à l'application d'un produit cosmétique, en particulier sur les cils ou les cheveux, du genre défini précédemment, est caractérisée par le fait que les poils de faible section sont réalisés en une matière thermoplastique ayant une température de fusion supérieure à la température de fusion de la matière élastomère thermoplastique dans laquelle sont réalisés les poils de section plus importante, la température de fusion de la matière thermoplastique des poils de faible section étant de l'ordre de 230° à 280°C, tandis que la température de fusion de la matière élastomère thermoplastique des poils de section plus importante est de l'ordre de 150° à 230°C ; de préférence, la différence de ces températures de fusion est de l'ordre de 50°C.According to the invention, a brush intended for the application of a cosmetic product, in particular to the eyelashes or the hair, of the kind defined above, is characterized in that the bristles of small section are made of a thermoplastic material having a melting temperature higher than the melting temperature of the thermoplastic elastomer material in which the bristles of more cross section are produced important, the melting temperature of the thermoplastic material of bristles of small cross section being of the order of 230 ° to 280 ° C., while the melting temperature of the thermoplastic elastomer material of bristles of larger cross section is of the order from 150 ° to 230 ° C; preferably, the difference in these melting temperatures is of the order of 50 ° C.

Avantageusement, les extrémités des poils de faible section, ainsi que les extrémités des poils de forte section comportent un renflement.Advantageously, the ends of the bristles of small section, as well as the ends of the bristles of large section have a bulge.

De préférence, le renflement de l'extrémité des poils de faible section a la forme d'une petite boule, tandis que le renflement situé à l'extrémité des poils de plus forte section a une forme plus aplatie et d'un plus grand diamètre, en forme de tête de champignon.Preferably, the bulge at the end of the bristles of small cross section has the shape of a small ball, while the bulge situated at the end of the bristles of larger cross section has a more flattened shape and a larger diameter. , shaped like a mushroom head.

Le nombre de poils par spire est avantageusement compris entre 7 et 55.The number of hairs per turn is advantageously between 7 and 55.

La proportion de poils de forte section relativement aux poils de faible section est comprise, de préférence, entre 1/4 et 4/1.The proportion of bristles of large section relative to bristles of small section is preferably between 1/4 and 4/1.

Les poils de faible section peuvent être réalisés en nylon ou en polyester, tandis que les poils de plus forte section sont réalisés en une matière thermoplastique relativement molle ou en une matière élastomère thermoplastique molle telle que les caoutchoucs EPDM, les polyesters ou les polyéther-bloc-amides.The bristles of small section can be made of nylon or polyester, while the bristles of larger section are made of a relatively soft thermoplastic material or of a soft thermoplastic elastomer material such as EPDM rubbers, polyesters or polyether-blocks. -amides.

Les poils de plus faible section ont généralement une section circulaire, qui peut être pleine ou creuse, ou peuvent présenter au moins une rainure capillaire comme prévu par FR-A-2 607 372.The bristles of smaller cross section generally have a circular cross section, which can be solid or hollow, or can have at least one capillary groove as provided by FR-A-2 607 372.

Une brosse conforme à l'invention permet de réaliser un maquillage spécifique.A brush according to the invention makes it possible to carry out specific makeup.

L'invention est également relative à un procédé de fabrication d'une brosse destinée à l'application d'un produit cosmétique, en particulier sur les cils ou les cheveux, comprenant une multitude de poils implantés transversalement dans une âme, en particulier formée par des spires d'un fil métallique torsadé, spires entre lesquelles les poils sont coincés, ces poils étant formés par un mélange de poils choisis parmi au moins deux groupes, à savoir un premier groupe constitué de poils de section relativement faible, en particulier inscrite dans un cercle de diamètre compris entre 6 et 13 centièmes de millimètre et un deuxième groupe de poils de section plus importante, en particulier inscrite dans un cercle de diamètre supérieur à 13 centièmes de millimètre et généralement inférieur à 30 centièmes de millimètre, les poils de faible section ayant une longueur suivant la direction radiale supérieure à celle des poils de forte section, sur une partie au moins de la brosse, le procédé étant caractérisé par le fait que les poils de faible section sont réalisés en une matière plastique ayant une température de fusion supérieure à la température de fusion de la matière plastique dans laquelle sont réalisés les poils de section plus importante, qu'une ébauche de brosse est réalisée avec des poils de petite section et de plus forte section ayant des longueurs voisines, et que la brosse est ensuite soumise à un traitement thermique sur au moins une partie de sa longueur, provoquant une diminution de longueur plus forte pour les poils de forte section que pour les poils de faible section.The invention also relates to a method of manufacturing a brush intended for the application of a cosmetic product, in particular to the eyelashes or the hair, comprising a multitude of bristles implanted transversely in a core, in particular formed by turns of a twisted metal wire, turns between which the hairs are wedged, these hairs being formed by a mixture of hairs chosen from at least two groups, namely a first group consisting of hairs of relatively small cross section, in particular included in a circle with a diameter between 6 and 13 hundredths of a millimeter and a second group of bristles with a larger section, in particular inscribed in a circle with a diameter greater than 13 hundredths of a millimeter and generally less than 30 hundredths of a millimeter, the bristles of small section having a length in the radial direction greater than that of the bristles of large section, over at least part of the brush, the method being characterized in that the bristles of small cross section are made of a plastic material having a melting temperature higher than the melting temperature of the plastic material in which the bristles of larger cross section are made, than a brush blank is produced with bristles of small section and larger section having similar lengths, and the brush is then subjected to a heat treatment over at least part of its length, causing a greater decrease in length for bristles of large cross-section than for bristles of small cross-section.

Le traitement thermique peut être effectué à l'air chaud, auquel cas les extrémités des poils, après traitement thermique, ne comportent pas de renflement.The heat treatment can be carried out with hot air, in which case the ends of the bristles, after heat treatment, do not have any bulge.

Selon une autre possibilité avantageuse, le traitement thermique est effectué avec une source de chaleur constituée par une flamme ou un chauffage infrarouge, les deux types de poils, suite à ce traitement thermique, présentant des extrémités munies d'un renflement.According to another advantageous possibility, the heat treatment is carried out with a heat source constituted by a flame or infrared heating, the two types of bristles, following this heat treatment, having ends provided with a bulge.

La source de chaleur peut s'étendre suivant une direction parallèle à l'âme de la brosse, à une distance appropriée et la brosse est soumise à un mouvement de rotation autour de l'axe de l'âme pour assurer un chauffage sensiblement homogène suivant toute la périphérie.The heat source can extend in a direction parallel to the core of the brush, at an appropriate distance and the brush is subjected to a rotational movement around the axis of the core to ensure substantially uniform heating according to the whole periphery.

De préférence, la température de fusion de la matière plastique des poils de faible section est de l'ordre de 230° à 280°C, tandis que la température de fusion de la matière plastique des poils de section plus importante est de l'ordre de 150° à 230°C.Preferably, the melting temperature of the plastic material of the bristles of small section is of the order of 230 ° to 280 ° C., while the melting temperature of the plastic material of the bristles of larger section is of the order from 150 ° to 230 ° C.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'un exemple de réalisation décrit avec référence au dessin ci-annexé, mais qui n'est nullement limitatif.

  • La figure 1, de ce dessin, illustre schématiquement une étape du procédé de fabrication d'une brosse selon l'invention.
  • La figure 2 montre schématiquement une brosse conforme à l'invention.
  • La figure 3 montre une variante de réalisation de brosse selon l'invention.
  • La figure 4, enfin, montre une autre variante de réalisation.
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with an exemplary embodiment described with reference to the attached drawing, but which is by no means limiting.
  • Figure 1 of this drawing schematically illustrates a step in the method of manufacturing a brush according to the invention.
  • Figure 2 schematically shows a brush according to the invention.
  • Figure 3 shows an alternative embodiment of the brush according to the invention.
  • Figure 4, finally, shows another alternative embodiment.

En se reportant à la figure 1 du dessin, on peut voir une étape de fabrication d'une brosse 1 pour l'application d'un produit cosmétique, en particulier de mascara, sur les cils. La brosse 1 comprend une âme métallique 2 formée par un fil de fer qui a été replié en U. Entre les branches parallèles du fil de fer ont été introduits des poils 3, 4, transversalement à la direction longitudinale de l'âme. Le fil de fer replié en U a ensuite été torsadé de sorte que les poils 3, 4 sont coincés entre les spires 5, 6 du fil métallique. L'âme 2 ainsi réalisée est fixée en bout d'une tige 7 de plus fort diamètre.Referring to Figure 1 of the drawing, we can see a step of manufacturing a brush 1 for applying a cosmetic product, in particular mascara, on the eyelashes. The brush 1 comprises a metallic core 2 formed by an iron wire which has been folded in a U shape. Between the parallel branches of the iron wire, hairs 3, 4 have been introduced, transverse to the longitudinal direction of the core. The wire folded into a U was then twisted so that the bristles 3, 4 are wedged between the turns 5, 6 of the metal wire. The core 2 thus produced is fixed at the end of a rod 7 of larger diameter.

Les poils 3 et 4 sont formés par un mélange de poils choisis parmi au moins deux groupes, à savoir un premier groupe constitué de poils 3 de section relativement faible, et un deuxième groupe de poils 4 de section plus importante.The bristles 3 and 4 are formed by a mixture of bristles chosen from at least two groups, namely a first group consisting of bristles 3 of relatively small section, and a second group of bristles 4 of larger section.

De préférence, les poils 3 ont une section qui s'inscrit dans un cercle dont le diamètre est compris entre 6 et 13 centièmes de millimètre. La section des poils 3 peut être circulaire, pleine ou creuse ou présenter au moins une rainure capillaire, comme dans FR-A-2 607 372.Preferably, the bristles 3 have a section which is inscribed in a circle whose diameter is between 6 and 13 hundredths of a millimeter. The section of the bristles 3 can be circular, solid or hollow or have at least one capillary groove, as in FR-A-2 607 372.

Les poils 4 ont une section dont le contour est compris entre un cercle dont le diamètre est supérieur à 13 centièmes de millimètre et un cercle dont le diamètre est généralement inférieur à 30 centièmes de millimètre.The bristles 4 have a section whose contour is between a circle whose diameter is greater than 13 hundredths of a millimeter and a circle whose diameter is generally less than 30 hundredths of a millimeter.

Le nombre de poils 3, 4 par spire de l'âme 2 est compris entre 7 et 55, de préférence entre 10 et 40. Il est clair que la représentation des figures 1 et 2, pour des raisons de clarté, ne correspond pas un tel nombre de poils.The number of bristles 3, 4 per turn of the core 2 is between 7 and 55, preferably between 10 and 40. It is clear that the representation of Figures 1 and 2, for reasons of clarity, does not correspond to a such number of hairs.

La proportion de poils 4 de forte section relativement aux poils 3 de faible section est avantageusement comprise entre 1/4 et 4/1.The proportion of bristles 4 of large section relative to the bristles 3 of small section is advantageously between 1/4 and 4/1.

A l'étape de fabrication illustrée sur la figure 1, les poils 3 et 4 ont sensiblement la même longueur radiale, et la forme générale de la brosse a été réalisée de manière classique à l'aide d'une tondeuse.In the manufacturing step illustrated in FIG. 1, the bristles 3 and 4 have substantially the same radial length, and the general shape of the brush has been produced in a conventional manner using a clipper.

Les poils 3 sont réalisés en une matière plastique ayant une température de fusion supérieure à celle de la matière plastique utilisée pour les gros poils 4.The bristles 3 are made of a plastic material having a melting temperature higher than that of the plastic material used for the large bristles 4.

La température de fusion de la matière plastique des poils 3 de faible section est de l'ordre de 250°C, tandis que la température de fusion de la matière plastique des gros poils 4 est de l'ordre de 180°C.The melting temperature of the plastic material of the bristles 3 of small section is of the order of 250 ° C., while the melting temperature of the plastic material of the large bristles 4 is of the order of 180 ° C.

Les poils 3 de faible section sont avantageusement réalisés en nylon ou en polyester, tandis que les poils 4, de plus forte section sont élastiques, et réalisés en une matière thermoplastique relativement molle.The bristles 3 of small section are advantageously made of nylon or polyester, while the bristles 4, of larger section are elastic, and made of a relatively soft thermoplastic material.

Dans un exemple de réalisation avantageux, les poils 3 de faible section sont réalisés en nylon et ont un diamètre de 8 centièmes de millimètre, tandis que les poils 4 de plus forte section ont un diamètre de 30 centièmes de millimètre.In an advantageous embodiment, the bristles 3 of small section are made of nylon and have a diameter of 8 hundredths of a millimeter, while the bristles 4 of larger section have a diameter of 30 hundredths of a millimeter.

Après que les poils de la brosse 1 aient été soumis à l'action d'une tondeuse, comme indiqué précédemment, les poils 3 et 4, qui alors ont sensiblement la même longueur, sont exposés à une source de chaleur 8 constituée par une rampe de rayonnement infrarouge ou par une flamme (ou une rampe de flammes) disposée à une distance appropriée de la brosse et s'étendant sensiblement suivant toute la longueur de l'âme 2, parallèlement à cette âme.After the bristles of the brush 1 have been subjected to the action of a clipper, as indicated above, the bristles 3 and 4, which then have substantially the same length, are exposed to a heat source 8 constituted by a ramp infrared radiation or by a flame (or a flame ramp) arranged at an appropriate distance from the brush and extending substantially along the entire length of the core 2, parallel to this core.

L'ensemble est agencé de manière que l'exposition des poils à la source de chaleur soit sensiblement uniforme sur tout le pourtour de la brosse. Pour cela, on communique avantageusement à la brosse 1 un mouvement lent de rotation autour de l'axe de l'âme 2 pour faire passer toutes les extrémités des poils devant la source de chaleur sensiblement linéaire, parallèle à une génératrice de la brosse.The assembly is arranged so that the exposure of the bristles to the heat source is substantially uniform over the entire periphery of the brush. For this, it advantageously communicates to the brush 1 a slow movement of rotation around the axis of the core 2 to pass all the ends of the bristles in front of the substantially linear heat source, parallel to a generator of the brush.

Lorsque la brosse a été soumise pendant un temps suffisant à la source de chaleur, les poils de forte section 4, comme illustré sur la figure 2, sont devenus nettement plus courts que les poils 3 de plus faible section. En outre, les extrémités des poils 3 présentent des renflements 9 en forme de petite boule, tandis que les extrémités des poils 4 présentent des renflements 10 plus importants en forme de tête de champignon ou de tête de clou.When the brush has been subjected for a sufficient time to the heat source, the bristles of large section 4, as illustrated in FIG. 2, have become significantly shorter than the bristles 3 of smaller section. In addition, the ends of the bristles 3 have bulges 9 in the form of a small ball, while the ends of the bristles 4 have larger bulges 10 in the form of a mushroom head or a nail head.

La combinaison de ces caractéristiques permet d'obtenir une brosse 1 assurant un fort chargement en produit cosmétique, lorsqu'elle est retirée du récipient contenant le produit. Une telle brosse donne un maquillage chargé, séparé, très différent de celui obtenu avec les brosses traditionnelles.The combination of these characteristics makes it possible to obtain a brush 1 ensuring a high loading of cosmetic product, when it is removed from the container containing the product. Such a brush gives a charged, separate make-up, very different from that obtained with traditional brushes.

Le traitement thermique de l'ébauche de brosse, comportant des poils 3 et 4 ayant sensiblement la même longueur, peut être effectué à l'air chaud. Par exemple un courant d'air chaud est envoyé sur toute ou partie de la longueur de la brosse, mise en rotation autour de son axe. La figure 3 illustre une brosse obtenue dans ces conditions, seule une partie 4 de cette brosse ayant été traitée. Dans la partie traitée H, les poils 4 de forte section ont une longueur plus faible que les poils 3 réalisés en une matière plastique ayant une température de fusion plus élevée. Contrairement au cas de la figure 2, les extrémités des poils 3 et 4 traités à l'air chaud sont dépourvus de renflement. Dans la partie non traitée de la brosse, les poils 3 et 4 ont sensiblement la même longueur.The heat treatment of the brush blank, comprising bristles 3 and 4 having substantially the same length, can be carried out with hot air. For example, a current of hot air is sent over all or part of the length of the brush, rotated around its axis. FIG. 3 illustrates a brush obtained under these conditions, only part 4 of this brush having been treated. In the treated part H, the bristles 4 of large section have a shorter length than the bristles 3 made of a plastic material having a higher melting temperature. Contrary to the case in FIG. 2, the ends of the bristles 3 and 4 treated with hot air are devoid of bulge. In the untreated part of the brush, the bristles 3 and 4 have substantially the same length.

La figure 4 montre une brosse ayant subi un traitement par rayonnement infrarouge ou à la flamme, comme pour la figure 2, mais sur une partie H de la longueur seulement. Dans la partie H, on trouve les poils 4 plus courts munis des renflements 10 et les poils 3 munis des boules 9. Dans la partie non traitée, les poils 3 et 4 ont sensiblement la même longueur.FIG. 4 shows a brush having undergone a treatment by infrared radiation or with a flame, as for FIG. 2, but only over part H of the length. In part H, there are the shorter bristles 4 provided with bulges 10 and the bristles 3 provided with balls 9. In the untreated part, the bristles 3 and 4 have substantially the same length.
