1. Field of the Invention
The invention relates to a brush for applying a cosmetic product to keratinous fibers, in particular for applying mascara to eyelashes or dye to hair, as well as a device for making up, including this brush. Most frequently the brush comprises an elongate core formed by helically winding two strands of metal wire, and bristles radially implanted into the core and tightly held between the wound strands, the brush having at least one concave cutback which holds the product during wiping.
2. Description of the Related Art
FR-A-2605 505 shows a brush of this kind which allows the product to be applied to be properly taken up. Such product is held in a reservoir whose outlet, traversed by the brush, is provided with a wiper element intended to limit the charge of the product taken up by the bristles. According to this known document, the edges or borders delimiting the cutback are substantially straight. The brush allows relatively different make-ups to be obtained according to the zones of the brush and the edges used and according to the movement imparted to the brush. For example, the user may obtain a relatively heavy make-up if she does not rotate the brush around its axis at the time of the application, but then the lashes are not perfectly separated. On the other hand, she can obtain a light make-up if she rotates the brush around its axis, thus using the edges bordering the cutback. In all modes of use, a difference of make-up will be observed between the lashes situated at the periphery of the eyelid and those at the center of the lid, which are better charged, better curved, and/or better separated than the lashes at the sides of the lid.
FR-A-2715038 describes brushes with a cutback allowing, on the one hand, the product to be spread better at its intended location, to obtain large variations in wiping on the brush and to improve the ergonomic features of the making up and, on the other hand, the use of only one kind of wiper and a single stem diameter, while having the possibility of causing the charge on the lashes to be considerably varied without basically modifying the elegance of the brush. This result is obtained by the general shape of the brush which is a double frustum of coaxial cones joined at their large bases with the same diameter, and by the fact that the edges or borders delimiting the cutback are not straight. The make-up obtained with this type of brush is usually characterized by a heavy charge at the base of the lashes and a small curvature of the lashes.
Although the conventional brushes yield overall satisfactory results, it is desirable to have brushes available which make it possible to makeup lashes so that they are strongly curved, separated at their ends and heavily charged, which can not be effected with conventional brushes.
It is an object of the invention to provide a brush which makes it possible to makeup on lashes so that they are strongly curved, separated at their ends and heavily charged.
It is another object of the invention to provide a brush which is simple and economic to make and convenient to use.
According to a first aspect of the invention, a brush for the application of a cosmetic product to the keratinous fibres comprises an elongate core with bristles radially implanted in the core, the axial limits of a cylindrical envelope of the brush comprising at least one concave cutback with a major length dimension (λ). Bristles of a larger dimension are contained in a cylindrical envelope with a central axis I—I and defining at least one crest zone. The width (l) of the cutback varies from one end of the brush to the other and has a single maximum width (L) between the ends.
Thus the brush has a cutback comprised of shorter bristles, these bristles being more heavily charged with mascara. The intersection of the cylindrical envelope with the cutback defines a side with a concave shape which, in contrast to the conventional brushes, follows the shape of the set of lashes of an eyelid. Thus when the user applies the brush to the lashes in the region of the cutback, she charges the base of the lashes with mascara over the whole width of the eyelid. Then by rotating the brush around its central axis, she spreads the mascara over the entire length of each lash while combining the lashes and separating all the lashes over their whole length. This makes it possible to obtain a makeup that is simultaneously copious, regular, elongating and curving.
This brush is perfectly suitable for the makeup of eyelashes. Thus, according to a second aspect of the invention, a makeup device comprises a mascara reservoir and a mascara applicator, wherein the applicator comprises a brush according to the first aspect.
Preferably the core is formed by the helical winding of two strands of a metal wire, with the bristles tightly held between the wound up strands of the core. Preferably, the cutback or cutbacks are formed by clipping the brush. The axis of the cylinder enveloping those bristles having the largest dimension is defined as the central axis of the brush.
Advantageously, the contour of the cutback comprises at least one edge with a substantially rounded shape, which is preferably substantially parallel to the central axis of the brush. The contour of the cutback defines an edge which is most frequently sharp, but which can be trimmed to give it a rounded shape. The cutback has a greatest depth (d) which is preferably chosen to be smaller than or equal to its greatest width (L) and which is situated in the middle of the cutback, so to follow the shape of the eyelid in a better way.
Advantageously, the major axis (having the length λ) is substantially parallel to the axis of the brush. Preferably, the minor axis (L) of the cutback is substantially perpendicular to the axis of the brush, and (L) is smaller than or equal to the length (λ) of the major axis of the cutback so as to follow the shape of the eyelid in a better way. Preferably the cutback is symmetrical relative to a plane passing through the minor axis (of maximum width L) and perpendicular to the central axis.
The ends of the brush may be of any shape; they may, for example, have a straight section perpendicular to the central axis, a spherical cap or a cone frustum whose axis coincides with the central axis of the brush and whose base has the same diameter as the base of the enveloping cylinder.
The brush may have several cutbacks situated along different planes or surfaces, two adjacent such cutbacks determining between them at least one crest zone with a variable width (the width of a crest zone is measured along a direction perpendicular to the central axis of the brush).
Moreover, the bristles of the brushes in accordance with the invention may be of any kind: with tapered ends, or fork-shaped, or in the shape of pinheads, or they may have been subjected to any kind of treatment known to those in the art.
A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
The enveloping surface of the brush is a cylinder with a central axis I—I. The brush 1 has a flat rear end 6 perpendicular to the axis I—I and frustoconical front end 5 coaxial with the axis I—I and has a base of the same diameter as the cylinder enveloping the brush and joined to the flat section 10 of the cylinder so as to be perpendicular to the axis I—I.
At its circumference, within the axial limits of the cylindrical envelope, the brush has three concave cutbacks 7 delimited by oval contours 8 with depth d and major axis length λ, and with a maximum width (minor axis) L such that λ>L>d. The contours 8 of the cutbacks have two rounded edges 8a and 8b substantially parallel to the axis I—I. The contours of the cutbacks define crest surfaces 9 at the enveloping cylinder of the brush.
In the example shown, the contour of the cutback is oval but it could also be circular (λ=L), elliptical, or constituted by two portions of intersecting circles whose concavities face one another.
The contours 8 of the cutbacks 7 define sharp edges 11 at the crest surfaces 9.
The cutbacks 7 are obtained by clipping the brush 1, that is, by cutting the bristles 4 of this brush with a clipper. Each of the cutbacks 7 is situated on the same side of the brush; i.e., they are not intersected by the core 2.
The contours 8 of the cutbacks 7 also do not reach the end planes 6, 10 of the cylinder, but in a variant provision could be made for the cutbacks to be tangential with or intersecting these end planes.
Each eyelash is charged over its whole length; there is no difference in make-up between the lashes at the sides of the lid and those of the center; the lashes are perfectly separated from one another, elongated and curved back.
The mascara brush of
To obtain an even more heavily charged make-up, in another variant the crest zones may comprise an alternation of rows of short bristles and long bristles.
The eye makeup device shown in
An applicator is intended to cooperate with the reservoir 220. This applicator is constituted by a gripping part 223 which supports the application element 230 comprising a stem 222 and a brush 201 identical with those shown in
When the application element 230 is taken out of the reservoir, the brush charged with mascara passes through the wiper 221 which wipes the long bristles of the crest zones much more extensively than the short bristles of the cutback. The application element in accordance with the invention can then be used to load the lashes.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is thereofre to be understood that the invention may be practiced otherwise than as specifically described herein.
