Abstract
A brush (200) has a straight stem (201) defining a main axis (X—X), a flexible core (202) having a first and a second end, the first end being integral with the stem, and bristles (204) implanted radially in the core. The end of the bristles defining the surface (205) of the brush have a first face, the intersection of any meridian plane passing through the main axis with the surface of the brush defining two peak lines (207) having a specific curvature. The core is curved, the peak lines (207) are convex, and the first face (207.1) is substantially straight and parallel to the main axis (X—X).
Description
The invention relates to a brush, in particular a brush for applying a cosmetic product to keratinous fibers, especially for applying a mascara to the eyelashes or a dye to the hair, and to a make-up device which comprises this brush and has a substantially plano-convex profile.
Conventionally, a brush for applying a cosmetic product comprises an elongate core formed by helically winding two branches of a metal wire and bristles implanted radially in this core and gripped between these wound branches. Such brushes may be of various shapes and may have cutouts. If these brushes are used for applying mascara to the eyelashes, such shapes and such cutouts are provided in order to make it possible to obtain more or less heavy make-up or a greater or lesser elongation and curving of the eyelashes.
The prior art, for example FR-A-2715038, discloses mascara brushes having a substantially convex shape, such as for example the shape of a rugby ball, a flat notch having been cut out in the brushes over their entire length. Since the bristles of the flat notch are short, they are wiped off only slightly on exit from the reservoir containing the mascara; such brushes provide very heavy make-up.
Brushes are also known having the shape of a portion of a torus, these brushes being obtained by twisting the core of a cylindrical brush in an arc of a circle. Such brushes have a convex face, a concave face and two substantially plane faces. Such brushes are not very easy to handle; in fact if the user rotates the stem of such a brush about its axis between her fingers, for example in order to apply a product to the eyelashes, she must continually correct the distance between the brush and the eyelashes. Moreover, it was found that such a brush loaded the eyelashes, but without smoothing them sufficiently. Brushes obtained by twisting the core of a cylindroconical brush in an arc of a circle have the same disadvantages.
Although these conventional brushes give substantially satisfactory results, it is desirable to have brushes which take good hold of the eyelashes in order to ensure effective smoothing of the product, good separation of the eyelashes, and a relatively light make-up. It is therefore an object of the invention to provide a brush useful for the simple, economical and practical application of makeup.
To this end, the invention provides a brush for applying a cosmetic product which, when used to apply mascara to the eyelashes, make it possible to obtain make-up which is natural, that is to say relatively light, but with the lashes appreciably lengthened, these brushes, moreover, being very easy to handle.
According to a first aspect of the invention, the brush comprises a straight stem defining a main axis; a flexible core comprising a first and a second end, the first end being integral with this stem; and bristles implanted radially in this core, the ends of the bristles defining the surface of the brush, this surface comprising a first face. The intersection of any plane which passes through the main axis, herein called the meridian plane, with the surface of the brush defines two convex curves (i.e., their concavity faces the inside of the brush) called peak lines, having a specific curvature. The first face is substantially straight and parallel to the main axis.
The curvature of each peak line is the reciprocal: l/r of its radius of curvature r. At each point of the core, the intersection of the surface of the brush with any plane perpendicular to the core defines a cross-section of the brush. Preferably, the core is centrally positioned in each cross-section of the brush. The faces are longitudinal portions of the surface of the brush.
Preferably, the surface of the brush comprises at least one second face, called a face of maximum curvature, at which the curvature of the peak lines passes through a maximum in the region of this second face.
Advantageously, the curvature of the peak lines has a single maximum. Preferably, the surface of the brush comprises a single straight face. More preferably, the curvature of the peak lines increases continuously from the straight face to the peak line of maximum curvature. Preferably, the face of maximum curvature and the straight face are diametrically opposite one another with respect to the core. Advantageously, the bristles of the same cross-section are all of the same length.
According to a second aspect of the invention, the brush is manufactured by the steps of forming a starting brush having a straight stem, and imparting a curve to the core in said meridian plane, said curve having a curvature substantially equal to the curvature of one of the two meridian lines of said meridian plane and being in an opposite direction to the curvature of one meridian line.
At each point of the core, the intersection of the surface of the starting brush with any plane perpendicular to the core defines a cross-section of the starting brush. Preferably, the starting brush is selected in such a way that the core is central in each cross-section of the starting brush.
The surface of the starting brush is thus modified in that one meridian line is converted into a substantially straight peak line, and the curvature of the second meridian line belonging to the same meridian plane is increased substantially. The core remains central in each cross-section of the brush, but these cross-sections are no longer parallel.
Desirably, a twist is imparted to said first end of the core in order to align the second end of the core with the main axis. The brush may thus be used with a mascara reservoir equipped with a wiper of conventional design.
Preferably, one of the meridian planes of the surface of the starting brush is a plane of symmetry of the starting brush. If appropriate, the starting brush comprises a plane of symmetry perpendicular to the axis of the core.
Preferably, the surface of this starting brush is a surface of revolution. Advantageously, each cross-section of the starting brush is convex.
This brush is perfectly suitable for making up eyelashes, and therefore a third aspect of the invention provides a make-up device comprising a mascara reservoir and a brush according to the invention for the application of mascara.
The brush according to the invention has a continuous evolute profile which is plano-convex in relation to its main axis, i.e., when the brush executes a revolution about its main axis, for example when the user rotates the stem of the brush between her fingers, it evolves from a substantially plane face, which surrounds the straight peak line parallel to the main axis, towards a convex face of increasing radius of curvature, to reach maximum curvature, then decrease and return to a plane face.
The substantially plane profile is located in the concavity of the brush. Since each cross-section is perpendicular to the core at any point of the latter, the bristles of the brush have a density higher than the rest of the brush along this plane profile. Moreover, these bristles converge. The density of the bristles decreases progressively from the plane face to the face of maximum curvature. Preferably, the face diametrically opposite the straight face with respect to the core is that having the greatest curvature. This face thus has a much lower bristle density, and these bristles diverge.
When the user uses this brush in order to apply a make-up product to the eyelashes, she extracts the brush from the product reservoir, the brush passing through a wiper. If the bristles in the same cross-section are all of the same length, they are all wiped. However, the face comprising a substantially plane profile is wiped to a lesser extent because the bristles converge and are very dense. By contract, the face having the greatest curvature is wiped to a greater extent, since the distribution of the bristles is highly spaced out. The user places the brush against the eyelashes and rotates it between her fingers: the brush loads each eyelash with product by means of its plane profile, then it combs the eyelash, lengthens it and curves it by means of the rest of its surface. The make-up thus obtained is relatively light, and the lash appreciably lengthened and highly curved.
Furthermore, the bristles of a brush according to the invention may be of any type: they may be bristles of different lengths, of different diameters or different cross-sections and of different materials, bristles with tapered ends, fork-shaped ends or ends in the form of a pinhead, or bristles which have undergone any kind of treatment known in the art.
There may also be provision for the brush according to the invention to comprise alternate rows of short bristles and long bristles, the long bristles alone defining the surface of the brush. Such a version of the invention makes it possible to increase the loading of the eyelid with product.
The helical winding of the two branches of the metal wire forming the core may be provided so as to have a right-hand pitch, as is conventional in the manufacture of make-up brushes, or a left-hand pitch, as taught by FR-A-27011098. To manufacture a brush with a left-hand pitch, the branches of the core are twisted by rotating them to the left in order to form turns which rotate clockwise around the core, starting from the stem and advancing towards the end of the brush.
The brush with a left-hand pitch is preferred for the production of brushes according to the invention: this gives the bristle turns an orientation which makes it possible to separate the eyelashes more effectively during make-up.
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:

FIG. 5 is a sectional view of an eye make-up device.
The brush 100 illustrated in FIGS. 1A and 1B comprises a straight stem 101 defining a main axis X—X. Fastened by force fitting to the end 101.1 of this stem 101 is an elongate core 102 (which has been illustrated in these figures, although it is hidden by the bristles of the brush) formed by the helical winding of two branches of a metal wire 103 which has been bent in the form of a U before the branches are twisted. The axis of the core 102 coincides with the main axis X—X. Bristles 104 are implanted radially between the branches of the wire 103. When the branches of the wire 103 are twisted, the bristles are gripped and held between the helical turns of the core 102. The ends of the bristles 104 define the surface of the brush 105: this is a surface of revolution which has the shape of a rugby ball and the ends of which consist of two cross-sections, namely the disk 106.a having the center 108.a and the disk 106.b having the center 108.b. Each cross-section 106 of the brush 100 has the shape of a disk, all the cross-sections 106 being parallel to one another. The intersection of the surface 105 with any meridian plane of the brush defines meridian lines 107 which are all identical and which have the same radius of curvature r.
A first twist is imparted to the core 102 in a meridian plane, between the cross-sections 106.a and 106.b, by means of a suitable tool, for example by pressing the core longitudinally around a metal cylinder having a radius of curvature r, in such a way that the said core takes the form of one of the meridian lines 107, and then a second twist is imparted thereto in the same plane, between the end 101.1 of the stem and the center 108.a of the end cross-section of the brush, so as to align the center 108.b of the other end of the brush with the main axis X—X, in the same way as the first end 108.a.
As a result of these operations, a brush 200 according to the invention, illustrated in FIGS. 2A and 2B, is obtained. In these figures, the reference numbers assigned to elements similar to those of FIGS. 1A and 1B are those of FIGS. 1A and 1B, increased by 100.
The brush of FIGS. 2A and 2B differs from that of FIG. 1 in that it has substantially the shape of an elongate banana, and in that the core 202 is curved, with a radius of curvature substantially equal to r. However, the centers of its ends 208.a and 208.b are aligned with the main axis X—X. The intersection of the surface 205 of the brush with the planes passing through the main axis X—X defines peak lines 207. FIG. 2B is obtained from FIG. 2A by a quarter-turn rotation about the main axis X—X. It can be seen in FIG. 2A that the cross-sections 206 converge, while the cross-sections 106 of the brush of FIG. 1 are parallel. The brush of FIG. 2A comprises a first substantially straight face 207.1, substantially parallel to the main axis X—X, and a second face 207.2 of maximum curvature, said faces being diametrically opposite one another with respect to the core 202. The passage from one peak line to another takes place continuously, with a continuous variation in the curvature from the face of maximum curvature 207.2 to the substantially straight face 207.1.
In FIGS. 3A and 3B, the reference numerals assigned to elements similar to those of FIGS. 1A and 1B are those of FIGS. 1A and 1B, increased by 200. The brush illustrated in FIGS. 3A and 3B differs from that of FIGS. 1A and 1B in its surface 305 which has the shape of a rugby ball comprising three substantially flattened faces 305.1, these three faces being separated from one from the other by rotation through 120° about the axis X—X. Each of the cross-sections 306 of the brush has the shape of a triangle with rounded corners. The meridian lines 307 have a variable curvature. The meridian lines 307.1 delimiting the faces 305.1 have the greatest curvature.
A first twist is imparted to the core 302 in the plane of one of the three meridian lines 307.1, between the ends 306.a and 306.b, by means of a suitable tool, for example by pressing the core longitudinally around a metal cylinder having a radius of curvature r′, in such a way that said core assumes the same curvature r′ as this meridian line 307.1, the twist being executed in the opposite direction to this meridian line so as to straighten the same; then, a second twist is imparted in the same plane, between the end 301.1 of the stem and the center 308.a of the end of the brush, so as to align the center 308.b of the other end of the brush with the main axis X—X in the same way as the center 308.a.
According to one version of the invention, the first twist may be imparted in the plane of any meridian line 307 in such a way that the core assumes the same curvature as this any meridian line 307 in the opposite direction to this meridian line. However, the selection of the meridian line having the greatest curvature makes it possible to obtain a brush whose plane part is denser and whose more curved part is more spaced out.
As the result of the operations described above, a brush 400 according to the invention, illustrated in FIGS. 4A and 4B, is obtained. The reference numbers assigned to elements similar to those of FIG. 3A are those of FIG. 3A, increased by 10.
The brush of FIGS. 4A and 4B differs from that of FIG. 2 in that the surface 405 has substantially the shape of an elongate banana comprising essentially three flattened faces. The core 402 is curved, its curvature r′ is substantially equal to that of the meridian line 307.1 of the starting brush of FIG. 3A. The intersection of the surface 405 of the brush with the planes passing through the main axis X—X defines peak lines. Here, the face of maximum curvature is the peak line 407.2. The substantially straight face 407.1 is diametrically opposite it with respect to the core.
FIG. 4B is obtained from FIG. 4A by a quarter-turn rotation about the main axis X—X. It can be seen in FIG. 4A that the cross-sections 406 converge while the cross-sections 306 of the brush of FIG. 3A are parallel. The evolution of the curvature of the peak lines about the main axis X—X is continuous.
The eye make-up device illustrated in FIG. 5 comprises a cylindrical reservoir 520 which has a threaded neck 524 surmounted by a seal 525 and which is filled with mascara 515. The reservoir 520 has a wiper 521 in its neck, the wiper being held in position in the neck by means of a bead 526 which cooperates with the shoulder separating the neck from the actual reservoir 520. The wiper 521 consists in a known way of a flexible and elastic material.
An applicator is intended for cooperating with the reservoir 520. The applicator consists of a grasping means 523 which supports the application member 530, the latter comprising a stem 522 and an application part 501 which are identical to those illustrated in FIGS. 2A and 2B. The grasping means 523 is in the form of a top and has a thread 523a cooperating with the thread 524a of the neck of the reservoir. The reservoir 520 is closed off sealingly by screwing the grasping means 523 onto the reservoir neck 524.
When the application member 530 is extracted from the reservoir, the applicator part 501 having the form of a brush loaded with mascara passes through the wiper 521. The latter wipes the bristles of the faces of high curvature to a much greater extent than the bristles of the straight faces.
When applied to the eyelashes, the brush loads each eyelash with product by means of its plane profile, then it combs the eyelash, elongates it and curves it using the rest of its surface.
In comparison with the conventional substantially convex brushes, the brush according to the invention affords the advantage of applying less product to the eyelashes. In comparison with brushes of varied curvatures, such as conventional curved cylindrical brushes (portions of a torus), the brush according to the invention affords the advantage of combining the eyelashes effectively, thus resulting in a better spreading of the product and a more pronounced lengthening and curving effect.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that the invention may be practiced otherwise than as specifically described herein.
