Description

FIBRE POUR APPLICATEUR, NOTAMMENT COSMETIQUE, ET APPLICATEUR CORRESPONDANT FIBER FOR APPLICATOR, ESPECIALLY COSMETIC, AND APPLICATOR THEREOF
La présente invention concerne une nouvelle fibre ayant des caractéristiques particulièrement intéressantes pour la réalisation duplicateurs comportant une pluralité de poils, tels que par exemple des pinceaux ou des brosses. L'invention trouve une application particulièrement avantageuse dans le domaine de l'application des produits cosmétiques.The present invention relates to a new fiber having particularly advantageous characteristics for producing duplicators comprising a plurality of bristles, such as, for example, paintbrushes or brushes. The invention finds a particularly advantageous application in the field of the application of cosmetic products.
On sait qu'un certain nombre de produits cosmétiques se présentent sous forme de liquide plus ou moins épais et doivent être distribués de façon aussi régulière que possible sur un support. C'est le cas, par exemple, d'un vernis à ongles, qui doit être déposé de façon uniforme sur l'ongle au moyen d'un pinceau pour former un film. C'est le cas également d'un mascara liquide, qui doit être déposé sur les cils au moyen d'une brosse. Dans tous les cas, il est souhaitable de ne retenir sur l'applicateur qu'une quantité minimum de produit à distribuer et, par conséquent, on recherche, d'une part, à réduire la mouillabilité des poils de l'applicateur vis à vis du produit à distribuer et, d'autre part, à améliorer le glissement du produit sur la fibre constituant les poils de façon à limiter au maximum l'accrochage dudit produit. Il est bien clair que les résultats .ci-dessus exposés sont également désirables dans des domaines autres que l'application des produits cosmétiques de sorte que l'invention ne saurait être limitée à ce seul domaine. La présente invention a donc pour objet une fibre monofilament en matière plastique ayant une section droite quelconque, dont l 'enveloppe circulaire a un diamètre compris entre 0,03 et 0,40 mm, caractérisée par le fait que la matière plastique constitutive de la fibre contient de 0,2 à 15 % en poids d'au moins un agent améliorant la caractéristique de glissement de la fibre et réduisant sa mouillabilité à l'eau et/ou aux solvants.It is known that a certain number of cosmetic products are in the form of a more or less thick liquid and must be distributed as regularly as possible on a support. This is the case, for example, with a nail polish, which must be deposited uniformly on the nail using a brush to form a film. This is also the case with a liquid mascara, which must be applied to the eyelashes by means of a brush. In all cases, it is desirable to retain on the applicator only a minimum quantity of product to be dispensed and, consequently, it is sought, on the one hand, to reduce the wettability of the hairs of the applicator with respect to of the product to be distributed and, on the other hand, to improve the sliding of the product on the fiber constituting the bristles so as to limit as much as possible the attachment of said product. It is quite clear that the results . above exposed are also desirable in fields other than the application of cosmetic products so that the invention cannot be limited to this single field. The subject of the present invention is therefore a monofilament plastic fiber having any cross section, the circular envelope of which has a diameter of between 0.03 and 0.40 mm, characterized in that the plastic material constituting the fiber contains from 0.2 to 15% by weight of at least one agent improving the sliding characteristic of the fiber and reducing its wettability with water and / or solvents.
Dans un mode préféré de réalisation, l'agent de glissement est choisi dans le groupe formé par le téflon, le nitrure de bore, le bi-sulfure de molybdène, les graphites, le fullérène et le talc. La section de la fibre peut être quelconque, en particulier plate, circulaire, polygonale, cruciforme, annulaire ou en forme de U ; la fibre peut également comporter au moins un canal capillaire de forme linéaire droite ou ondulée et dont la section peut ne pas être symétrique. La matière plastique constitutive de la fibre est avantageusement choisie dans le groupe formé par les polyamides, les polyesters, les polyéther-bloc-amides et le polytétrafluoroéthylène. Lorsque la fibre est constituée d'un polyamide, on peut notamment utiliser les polyamides 6, 6-6, 6-10, 6-12 ou 11. L'extrémité de la fibre peut être traitée, par exemple par meulage, ou à chaud.In a preferred embodiment, the slip agent is chosen from the group formed by teflon, boron nitride, molybdenum bi-sulfide, graphites, fullerene and talc. The fiber section can be any, in particular flat, circular, polygonal, cruciform, annular or U-shaped; fiber can also include at least one capillary channel of straight or wavy linear shape and the section of which may not be symmetrical. The plastic material constituting the fiber is advantageously chosen from the group formed by polyamides, polyesters, polyether-block amides and polytetrafluoroethylene. When the fiber consists of a polyamide, polyamides 6, 6-6, 6-10, 6-12 or 11 can in particular be used. The end of the fiber can be treated, for example by grinding, or hot .
La présente invention a également pour objet un applicateur de produit liquide comportant une pluralité de poils reliés mécaniquement à un même élément, dont la manoeuvre permet la répartition du produit en couche sur un support, caractérisé par le fait qu'au moins une partie des poils de l'applicateur est constituée par des tronçons de fibres telles que ci-dessus définies. Selon une première variante, l'applicateur selon l'invention constitue un pinceau, dont les poils sont sensiblement parallèles et portés par un manche : c'est le cas, notamment, pour un applicateur de vernis à ongles. Selon une deuxième variante, l'applicateur selon l'invention constitue une brosse à cheveux, dont les poils sont implantés par touffes sur un support tel qu'une platine. Selon une troisième variante, l'applicateur selon l'invention constitue une brosse, dont les poils sont serrés par leur zone centrale dans une âme, les poils ayant approximativement une direction radiale par rapport à l'âme ; dans cette variante, l'âme peut être constituée d'un fil métallique torsadé de 0,3 à 0,9 mm de diamètre, les poils de la brosse étant bloqués dans les torsades de l'âme : c'est le cas, notamment, pour une brosse de mascara.The present invention also relates to a liquid product applicator comprising a plurality of bristles mechanically connected to the same element, the operation of which allows the distribution of the product in a layer on a support, characterized in that at least part of the bristles of the applicator is constituted by sections of fibers as defined above. According to a first variant, the applicator according to the invention constitutes a brush, the bristles of which are substantially parallel and carried by a handle: this is the case, in particular, for a nail varnish applicator. According to a second variant, the applicator according to the invention constitutes a hair brush, the bristles of which are implanted in tufts on a support such as a plate. According to a third variant, the applicator according to the invention constitutes a brush, the bristles of which are clamped by their central zone in a core, the bristles having approximately a radial direction relative to the core; in this variant, the core may consist of a twisted metal wire of 0.3 to 0.9 mm in diameter, the bristles of the brush being blocked in the twists of the core: this is the case, in particular , for a mascara brush.
Dans un applicateur selon l'invention, il est possible qu'une partie seulement des poils soit constituée de fibres selon l'invention. Les fibres ayant des caractéristiques améliorées de glissement, peuvent être ou bien mélangées statistiquement avec des fibres de type classique, de même section que la section des fibres à caractéristiques améliorées de glissement ou de section différente, ou bien, au contraire, localisées sur certaines zones de l'applicateur. Par exemple, dans le cas d'un pinceau pour vernis à ongles, la partie centrale du pinceau peut être constituée par des fibres de type classique alors que la partie périphérique est constituée de fibres à caractéristique de glissement élevée.In an applicator according to the invention, it is possible that only part of the bristles is made up of fibers according to the invention. The fibers having improved sliding characteristics, can either be statistically mixed with fibers of conventional type, of the same section as the section of fibers with improved sliding characteristics or of different section, or else, on the contrary, located in certain areas of the applicator. For example, in the case of a nail varnish brush, the central part of the brush can be constituted by fibers of the conventional type while the peripheral part consists of fibers with high sliding characteristic.
On a constaté que l'utilisation des fibres selon l'invention pour la réalisation d'applicateurs cosmétiques présentait des avantages très significatifs. En premier lieu, le produit se répartit mieux sur les poils de l'applicateur, ce qui permet d'utiliser des poils de diamètre plus important, d'une part, et d'augmenter la rapidité d'application du produit sur le support, d'autre part. En outre, le produit a plus tendance à rester sur le support que sur les poils de l'applicateur, ce qui permet de réaliser une distribution en couche plus importante. Dans le cas particulier des brosses de mascara, notamment du type spirale, on sait que les réservoirs de mascara comportent des diaphragmes servant à l'essorage de la brosse à chaque fois qu'on l'extrait du réservoir ; on a constaté qu'avec les fibres selon l'invention, l'essorage répartissait parfaitement le produit sur les poils de la brosse et qu'en outre, la brosse était moins encrassée et donc moins contaminée, étant donné que le produit glisse le long des poils à chaque application et se renouvelle régulièrement au lieu de former des résidus le long des poils. On a constaté également que l'application du mascara sur les cils s'effectue de façon plus douce et donne naissance à un film plus régulier.It has been found that the use of the fibers according to the invention for the production of cosmetic applicators has very significant advantages. Firstly, the product is better distributed over the bristles of the applicator, which makes it possible to use bristles of larger diameter, on the one hand, and to increase the speed of application of the product to the support, on the other hand. In addition, the product has a greater tendency to remain on the support than on the bristles of the applicator, which makes it possible to achieve a greater distribution in layers. In the particular case of mascara brushes, in particular of the spiral type, it is known that the mascara tanks have diaphragms serving to wipe the brush each time it is extracted from the tank; it was found that with the fibers according to the invention, the wringing distributed the product perfectly over the bristles of the brush and that, in addition, the brush was less fouled and therefore less contaminated, since the product slides along hairs with each application and is renewed regularly instead of forming residues along the hairs. It has also been found that the application of the mascara to the eyelashes is carried out more gently and gives rise to a more regular film.
Dans le cas des pinceaux pour vernis à ongles ou pour "eye-liner" , on a constaté que l'utilisation des fibres selon l'invention permettait une répartition rapide et homogène du produit même si les poils du pinceau ont un diamètre plus important qu'habituellement. La couche déposée sur le support est généralement plus épaisse qu'avec les applicateurs de l'état de la technique.In the case of brushes for nail varnish or for "eyeliner", it has been found that the use of the fibers according to the invention allows rapid and uniform distribution of the product even if the bristles of the brush have a larger diameter than 'habitually. The layer deposited on the support is generally thicker than with the applicators of the prior art.
Pour mieux faire comprendre l'objet de l'invention, on va en décrire maintenant, à titre d'exemples purement illustratifs et non limitatifs, trois modes de mise en oeuvre. EXEMPLE 1 :To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting examples, three modes of implementation. EXAMPLE 1:
On réalise une brosse spiralée destinée au maquillage des cils au moyen d'un mascara liquide constitué d'une composition aqueuse ayant une viscosité de 90 poises (9 Pa.s). Les poils de la brosse sont constitués par des fibres en polyamide "nylon 6-10" comportant 8 % en poids de nitrure de bore (BN)6. La brosse est constituée d'une âme en fil de fer torsadé ayant un diamètre de 0,7 mm, les torsades de l'âme retenant par leur zone centrale environ 500 poils qui sont uniformément répartis en 17 spires correspondant aux torsades de l'âme. La brosse a une forme cylindrique de 26 mm de longueur et de 6,5 mm de diamètre. Les poils de la brosse ont un diamètre de 0,15 mm et leur section est une section circulaire pleine. On constate que, sur une telle brosse, l'effet de spire est assez peu marqué, ce qui permet, de façon connue, d'obtenir un maquillage de bonne qualité. On constate que l'utilisation des fibres contenant du nitrure de bore comme ci-dessus indiqué permet d'améliorer de façon sensible la douceur du maquillage, son homogénéité et sa rapidité. En outre, après un nombre donné d'applications, la brosse est moins encrassée au voisinage de l'âme que dans le cas d'une brosse de construction identique réalisée avec des poils constitués par des tronçons de fibres ayant les mêmes caractéristiques, à ceci près qu'elles ne contiennent pas de nitrure de bore. EXEMPLE 2 :A spiral brush intended for making up the eyelashes is produced using a liquid mascara consisting of an aqueous composition having a viscosity of 90 poises (9 Pa.s). The bristles of the brush consist of polyamide "nylon 6-10" fibers comprising 8% by weight of boron nitride (BN) 6. The brush consists of a core of twisted wire having a diameter of 0.7 mm, the twists of the core retaining by their central zone approximately 500 bristles which are uniformly distributed in 17 turns corresponding to the twists of the core . The brush has a cylindrical shape of 26 mm in length and 6.5 mm in diameter. The bristles of the brush have a diameter of 0.15 mm and their section is a solid circular section. It can be seen that, on such a brush, the coiling effect is not very marked, which makes it possible, in known manner, to obtain makeup of good quality. It is noted that the use of fibers containing boron nitride as indicated above makes it possible to appreciably improve the softness of the makeup, its homogeneity and its speed. In addition, after a given number of applications, the brush is less fouled in the vicinity of the core than in the case of a brush of identical construction produced with bristles constituted by sections of fibers having the same characteristics, for this except that they do not contain boron nitride. EXAMPLE 2:
On réalise des fibres en polyester contenant 10 % en poids de téflon. Ces fibres ont une section droite cruciforme contenue dans une enveloppe circulaire ayant un diamètre de 0, 15. mm.Polyester fibers are produced containing 10% by weight of teflon. These fibers have a cruciform cross section contained in a circular envelope having a diameter of 0.15 mm.
Au moyen de ces fibres, on réalise un pinceau constitué de poils parallèles ayant une longueur de 17 mm. Ce pinceau comporte 150 poils. On utilise le pinceau avec un vernis à ongles ayant une viscosité de 4 poises (0,4 Pa.s). On constate que la couche de vernis à ongles obtenue sur un ongle est parfaitement répartie et plus épaisse qu'avec les pinceaux de l'état de la technique. EXEMPLE 3 : On réalise des fibres en polyéther-bloc-amide contenant 6 % en poids de bisulfure de molybdène. Ces fibres ont une section droite circulaire et comportent une rainure capillaire longitudinale. Le diamètre de la section droite est d'environ 0,3 mm ; la rainure capillaire a, sur la périphérie de la fibre, une largeur d'environ 0,06 mm et cette rainure a une profondeur d'environ 0,06 mm. Les fibres ci-dessus définies sont utilisées pour réaliser les poils d'une brosse pour cheveux. Chaque poil a une longueur de 35 mm au dessus de la platine, qui constitue le support. Les poils sont implantés par touffes de 10 poils, le maintien en position des poils étant effectué, de façon connue, en recourbant en U des tronçons de fibres de longueur double et en enfonçant les touffes dans un logement au moyen d'un arrêtoir inséré à force.Using these fibers, a brush is made up of parallel bristles having a length of 17 mm. This brush has 150 bristles. The brush is used with a nail varnish having a viscosity of 4 poises (0.4 Pa.s). It can be seen that the layer of nail varnish obtained on a nail is perfectly distributed and thicker than with the brushes of the prior art. EXAMPLE 3 Polyether-block amide fibers are produced containing 6% by weight of molybdenum disulphide. These fibers have a circular cross section and have a longitudinal capillary groove. The diameter of the cross section is approximately 0.3 mm; the capillary groove has, on the periphery of the fiber, a width of approximately 0.06 mm and this groove has a depth of approximately 0.06 mm. The fibers defined above are used to make the bristles of a hair brush. Each pile has a length of 35 mm above the plate, which constitutes the support. The bristles are implanted in tufts of 10 bristles, the holding in position of the bristles being carried out, in known manner, by bending U-shaped sections of fibers of double length and by pushing the tufts into a housing by means of a retainer inserted at strength.
On utilise une telle brosse pour étaler sur la chevelure d'un sujet un produit de traitement ayant une viscosité de 3 poises (0,3 Pa.s) secondes. On constate que l' enduction de la chevelure s'effectue de façon plus régulière qu'avec une brosse de l'état technique et que le brossage des cheveux est plus agréable pour le sujet traité.Such a brush is used to spread over the hair of a subject a treatment product having a viscosity of 3 poises (0.3 Pa.s) seconds. It is noted that the coating of the hair is carried out more regularly than with a brush of the technical state and that the brushing of the hair is more pleasant for the subject treated.
Il est bien entendu que les modes de réalisation ci-dessus décrits ne sont aucunement limitatifs et pourront donner lieu à toute modification désirable, sans sortir pour cela du cadre de l'invention. It is understood that the embodiments described above are in no way limiting and may give rise to any desirable modification, without departing from the scope of the invention.
