Description
BACKGROUND OF THE INVENTION
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.
SUMMARY OF THE INVENTION
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 (.lambda.). 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 .lambda.) 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
(.lambda.) 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 to 4, there may be seen a brush 1 for the
application of a cosmetic product, in particular for the
application of mascara to the eyelashes, comprising an elongate
core 2 formed by the helical winding of two strands of a metal wire
3. The core 2 is folded into a U before the strands are twisted.
The core 2 is force-fitted to the end of a stem t. Bristles 4 are
radially implanted between the strands of the wire 3. When the
strands of the wire 3 are twisted, the bristles are tightly held
and kept in position between the helical turns of the core 2. The
core 2 may be central, that is to say the core 2 defines an axis
coinciding with the central axis I--I of the brush, as in the
Figures, but it could instead be eccentric. The bristles 4 may be
made of natural or synthetic fibres and may possibly be flocked;
the brush 1 may comprise a mixture of bristles of different types
(different diameters, shapes, cross-sections).
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 .lambda., and with a
maximum width (minor axis) L such that .lambda.>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 (.lambda.=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.
In FIGS. 5 to 7, which illustrate the method of use of the brushes
according to the invention, the elements identical with, or
performing functions similar to, the elements described above will
be designated by the same reference numerals. Their description
will not be repeated, or will only be discussed briefly. For the
sake of simplification, the brushes shown in these Figures have a
single cutback, but the functioning would be the same if the brush
had several cutbacks.
In FIG. 5 there can be seen the whole set of the lashes of an
eyelid C engaged by the shortest bristles of the brush, situated in
the hollow of the concave cutback 7, which bristles are heavily
charged with mascara. On contact with these bristles, the root end
of each of the lashes will itself become heavily charged with
mascara. When the user rotates the brush 1 about its axis (FIG. 6),
the shape of the cutback ensures that the eyelashes continue to be
in contact with the brush over their whole length and continue to
be charged while being curved by the brush. The longer bristles of
the edge 11 start combing the eyelash. As the user continues to
rotate the brush (FIG. 7), the eyelashes are taken over by the
longest bristles of the crest zone 9 which bristles have a
cylindrical envelope and spread the product over the whole length
of each lash, while combing. If the brush has several cutbacks,
these charging and spreading-combing operations are repeated
several times in the course of one complete rotation of the
brush.
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 FIG. 8 differs from that shown in FIGS. 1 to 4
by the variation of the density of the bristles. The cutbacks 107
are situated in zones with a low bristle density, which allows them
individually to charge even more mascara. The end zones 112 and 113
of the brush as well as the crest zones 109 have a higher
population density of bristles, which makes it possible to enhance
the efficiency of the combing and of the separation of the
lashes.
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 FIG. 9 has a cylindrical reservoir
220 with a threaded neck 224 surmounted by a gasket 226 and which
is filled by mascara 215. The reservoir 220 has a wiper 221 made of
a conventional flexible and elastic material and held in the neck
via a bead 226 which cooperates with the shoulder separating the
neck from the main part of the reservoir 220.
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 FIGS. 1 to 4. The gripping part 223
is cap-shaped and has a thread 223a which cooperates with the
thread 224a of the neck of the reservoir. The leakproof obturation
of the reservoir 220 is obtained by screwing the gripping part 223
onto the neck 224 of the reservoir provided with gasket 225.
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.
