The brush enables the application of liquid or pasty mascara on the eyelashes.

Description

"Brosse à mascara perfectionnée" . "Advanced mascara brush".
La présente invention a essentiellement pour objet une brosse perfectionnée pour l'application de mascara liquide ou pâteux.The present invention essentially relates to an improved brush for applying liquid or pasty mascara.
On connaît déjà des brosses à mascara constituées essentiellement d'une tige ou analogue munie d'au moins une nappe de poils sensiblement parallèles les uns aux autres.We already know mascara brushes consisting essentially of a rod or the like provided with at least one layer of bristles substantially parallel to each other.
Toutefois, les poils de la brosse sont rectilignes et parallèles sur au moins une bonne partie de leur longueur de sorte que lorsque l'utilisatrice fait pivoter, sans translation, la brosse autour de son axe, les cils à maquiller, ou à tout le moins certains d'entre eux, peuvent passer entre les poils adjacents de la brosse sans pratiquement aucun contact des cils avec les poils, c'est- à-dire sans prélèvement de mascara, de sorte que la brosse devient alors inefficace pour appliquer du mascara sur les cils d'une façon régulière et homogène.However, the bristles of the brush are straight and parallel over at least a good part of their length so that when the user rotates, without translation, the brush around its axis, the eyelashes to be made up, or at the very least some of them can pass between the adjacent bristles of the brush without practically any contact of the eyelashes with the bristles, that is to say without removing mascara, so that the brush then becomes ineffective in applying mascara to eyelashes in a regular and homogeneous way.
Aussi, l'invention a pour but de remédier notamment à cet inconvénient en proposant une brosse à mascara qui, dans tous les cas et notamment lors de sa rotation autour de son axe, assurera une application fiable et homogène du mascara sur les cils de l'oeil.Also, the invention aims to remedy this drawback in particular by proposing a mascara brush which, in all cases and in particular during its rotation about its axis, will ensure a reliable and uniform application of the mascara on the eyelashes of the eye. 'eye.
A cet effet, l'invention a pour objet une brosse à mascara perfectionnée du type comprenant une tige ou analogue munie d'une nappe de poils, caractérisée en ce que les poils de la nappe, tous situés dans le plan de la nappe, forment chacun une ondulation dans le plan de ladite nappe en demeurant tous sensiblement parallèles les uns aux autres.To this end, the subject of the invention is an improved mascara brush of the type comprising a rod or the like provided with a layer of bristles, characterized in that the bristles of the layer, all situated in the plane of the layer, form each undulating in the plane of said sheet while all remaining substantially parallel to each other.
Selon une autre caractéristique de cette brosse, l'ondulation de chaque poil correspond à une longueur d'au moins une demi-longueur d'onde. On précisera encore ici que l'ondulation de chaque poil correspond à une longueur comprise entre une demi-longueur d'onde et une longueur d'onde et demie.According to another characteristic of this brush, the waviness of each bristle corresponds to a length of at least half a wavelength. It will also be specified here that the waviness of each hair corresponds to a length between a half wavelength and a wavelength and a half.
Suivant une réalisation préférée, l'ondulation de chaque poil a une forme correspondant sensiblement à la distance creux à crête d'une longueur d'onde.According to a preferred embodiment, the waviness of each bristle has a shape corresponding substantially to the hollow to peak distance of a wavelength.
Suivant une autre caractéristique de la brosse selon cette invention, l'amplitude de l'ondulation- de chaque poil correspond à une valeur comprise entre environ 40 % et 80 % de l'intervalle entre deux poils adjacents.According to another characteristic of the brush according to this invention, the amplitude of the waviness of each bristle corresponds to a value between approximately 40% and 80% of the interval between two adjacent bristles.
L'intervalle entre deux poils adjacents et parallèles pourra, suivant une réalisation préférentielle, être compris entre environ 0,2 et 0,50 millimètre.The interval between two adjacent and parallel bristles may, according to a preferred embodiment, be between approximately 0.2 and 0.50 millimeter.
Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which:
La figure 1 représente à très grande échelle et de manière quelque peu déformée pour plus de clarté, une brosse à mascara conforme aux principes de l'invention.Figure 1 shows on a very large scale and somewhat distorted for clarity, a mascara brush according to the principles of the invention.
La figure 2 est un schéma illustrant une ondulation d'une longueur d'onde et demie, pour permettre une explication claire de la forme des poils ondulés de la brosse selon l'invention.Figure 2 is a diagram illustrating a wavelength of a wavelength and a half, to allow a clear explanation of the shape of the wavy bristles of the brush according to the invention.
En se reportant notamment à la figure 1, on voit une brosse à mascara conforme à cette invention qui comprend essentiellement une tige 1 comportant une partie 2 formant manche et une partie opposée 3 dans laquelle est implantée, par tout moyen approprié connu, une nappe 4 de poils 5.Referring in particular to FIG. 1, there is seen a mascara brush according to this invention which essentially comprises a rod 1 comprising a part 2 forming a handle and an opposite part 3 in which is implanted, by any known suitable means, a ply 4 hair 5.
Selon une caractéristique essentielle de cette brosse, les poils 5 de la nappe 4 sont tous situés dans le plan de la nappe et forment chacun une ondulation dans ce plan en demeurant tous sensiblement parallèles les uns aux autres, comme cela apparaît clairement sur la figure 1.According to an essential characteristic of this brush, the bristles 5 of the ply 4 are all located in the plane of the ply and each form an undulation in this plane in all remaining substantially parallel to each other, as is clear from Figure 1.
Suivant un exemple de réalisation, l'ondulation que forme chaque poil 5 correspond à une longueur d'au moins une demi-longueur d'onde.According to an exemplary embodiment, the ripple that forms each hair 5 corresponds to a length of at least half a wavelength.
Plus précisément, comme on le voit bien sur la figure 2, l'ondulation de chaque poil 5 visible sur la figure 1 correspond sensiblement à la distance t creux B à crête C d'une longueur d'onde matérialisée par la courbe qui s'étend entre les points X et Y. Ainsi, comme on le comprend bien, la distance (. correspond à une demi- longueur d'onde.More precisely, as can be seen in FIG. 2, the undulation of each pile 5 visible in FIG. 1 corresponds substantially to the distance t hollow B to peak C of a wavelength materialized by the curve which s extends between the points X and Y. Thus, as it is well understood, the distance (. corresponds to a half wavelength.
Cela dit, l'ondulation que forme chaque poil 5 peut parfaitement, sans sortir du cadre de l'invention, correspondre à une longueur comprise entre une demi- longueur d'onde et une longueur et demie soit la longueur X-Z illustrée par la figure 2.That said, the ripple that forms each hair 5 can perfectly, without departing from the scope of the invention, correspond to a length between half a wavelength and a length and a half is the length XZ illustrated in Figure 2 .
Par ailleurs, conformément à l'invention, l'amplitude AFurthermore, in accordance with the invention, the amplitude A
(voir figure 2) de l'ondulation de chaque poil 5 correspondra à une valeur comprise entre environ 40 % et 80 % de l'intervalle E (voir figure 1) entre deux poils adjacents.(see Figure 2) of the waviness of each bristle 5 will correspond to a value between approximately 40% and 80% of the interval E (see Figure 1) between two adjacent bristles.
Suivant un mode de réalisation préféré, l'intervalle E entre deux poils adjacents 5 pourra être égal à environ 0,35 millimètre, de même que le diamètre de chaque poil 5 pourra être compris entre environ 0,30 et 0,50 millimètre, et sera par exemple égal à 0,35 millimètre.According to a preferred embodiment, the interval E between two adjacent bristles 5 may be equal to approximately 0.35 millimeter, just as the diameter of each bristle 5 may be between approximately 0.30 and 0.50 millimeter, and will for example be equal to 0.35 millimeter.
Dès lors, avec un espace ou intervalle E entre deux poils 5 de 0,35 millimètre, si l'on adopte 60 % de cette valeur pour l'amplitude A de l'ondulation que forme chaque poil 5, ladite amplitude A sera égale à sensiblement 0, 2 millimètre. On a donc réalisé suivant l'invention une brosse à mascara dont les poils ondulés dans un même plan favoriseront avantageusement le frottement entre les cils de l'oeil et les poils 5 lors de la rotation de la brosse autour de son axe, de sorte qu'un contact de tous les cils de l'oeil avec les poils de la brosse sera nécessairement réalisé et que, par conséquent, le maquillage des cils avec le mascara sera nécessairement régulier, homogène et uniforme.Consequently, with a space or interval E between two bristles 5 of 0.35 millimeter, if we adopt 60% of this value for the amplitude A of the ripple formed by each bristle 5, said amplitude A will be equal to substantially 0.2 millimeters. A mascara brush has therefore been produced according to the invention, the bristles wavy in the same plane will advantageously promote the friction between the eyelashes of the eye and the bristles 5 during the rotation of the brush around its axis, so that contact of all the eyelashes of the eye with the bristles of the brush will necessarily be made and that, consequently, the makeup of the eyelashes with the mascara will necessarily be regular, homogeneous and uniform.
Une telle brosse peut avantageusement être réalisée en une seule pièce moulée en une matière plastique appropriée lui donnant en quelque sorte la configuration d'un peigne.Such a brush can advantageously be produced in a single piece molded from a suitable plastic material giving it in a way the configuration of a comb.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre des revendications qui suivent . On the contrary, the invention includes all the technical equivalents of the means described as well as their combinations if these fall within the scope of the claims which follow.
