Connected plurality of twisted wire mascara brushes
Abstract
A plurality of twisted wire mascara brushes connected along the
lengths of their perspective metal cores, yielding zones on the
plurality of brushes that has bristles from only one brush, and
zones where the fibers intermingle from the plurality of brushes.
This creates different zones of fiber density, the low fiber
density zones will apply the mascara while the higher density fiber
zones will comb and separate the lashes. This plurality of
connected twisted mascara brushes is attached to a single stem.

Description
BACKGROUND
[0001] This invention relates to an applicator for a pastry
cosmetic product, notably mascara.
BACKGROUND OF THE INVENTION
[0002] The invention relates an applicator for a pastry cosmetic
product notably mascara.
[0003] The purpose of a mascara applicator is to apply a rich coat
of mascara to the eyelashes, while separating and lengthening them.
Traditional mascara brushes are composed of a single twisted wire
which fixes the bristles between them in a helical array. Due to
the high viscosity of mascara, which is necessary to lay a thick
coating on the lashes, mascara has a tendency to clump the lashes
together and give an uneven application of the product on the
lashes. Mascara brushes with a density of fibers too low will apply
too much mascara on the lashes and lead to clumping of the lashes
and uneven distribution while mascara brushes with a high density
of fibers will not apply sufficient quantity of mascara on the
lashes. A similar trade-off is made while selecting the flexural
strength of the brushes. Soft fibers (ones with a low flexural
strength) apply mascara to the lashes but do not separate the
lashes, because they simply flex and do not resist enough to
penetrate the lashes well enough to comb the lashes. Stiffer fibers
(fibers with a relatively high flexural strength) lengthen and
separate the lashes well, but do not do a good job of applying
mascara to the lashes. Clearly there exists a need for a mascara
brush that both separates the lashes, and transfers a rich quantity
of mascara to the lashes.
BRIEF SUMMARY OF THE INVENTION
[0004] This invention consists of two spiral mascara brushes
connected along the lengths of their perspective metal cores. The
advantage of that simple concept gives to the application of
mascara is first that around the circumference of the brush the
density of fibers will vary. In the parts of the brush where there
is no overlapping of the brushes, the fiber density will be low,
giving more volume to the lashes. In the zones of the brush where
the brushes do overlap and the fibers from each of the two brushes
intermingle there will be a higher density of fibers, resulting in
a better combing and separation of the lashes. Both zones are
necessary to optimize the application of mascara, one zone that
yields volume and another zone that separates and extends the
lashes. Also a grip placed on the handle would aid the user to
orient the brush correctly, so that the lashes would first pass
through the zone with the low fiber density, then be combed when
they pass through the high density fiber zone.
[0005] Another possibility that this invention opens up is that
besides having a different fiber density the double brush can be
made of two brushes with fibers of different flexural strength. For
example one twisted brush can have fibers of low flexural strength
that deposit a rich quantity of mascara on the lashes, while the
second brush can be made of fibers with a higher flexural strength
to comb and separate the lashes. This could also be in combination
with brushes having a different fiber density to optimize the
application, combing, and separating of the lashes.
[0006] This invention has a zone of the brush that serves to coat
the lashes and another that serves to separate the lashes. In every
pass of the mascara brush, the lashes are exposed to and immersed
in both of these zones.
[0007] U.S. Pat. Nos. 6,397,855 and 6,408,857 show a mascara
brushes configured in a loop, being they are configured in a loop,
this signifies that there is a distance between the two sections of
the brushes. The bristles from each section do not intermingle
throughout the length of this brush, as in the present
invention.
[0008] U.S. Pat. Nos. 5,611,361, 4,600,328, and 5,052,839 show a
plurality of applicators; however these applicators are spaced
apart from each other, on different stems or tines, not
connected.
[0009] The purpose of these applicators is to coat the lashes from
each side, whereas the purpose of the present invention is to
provide one zone of the brush that will provide volume and another
zone of the brush to comb, and separate the lashes.
[0010] U.S. Pat. No. 4,458,701 also shows a dual brush mascara
applicator. In this applicator, the brushes are separated, and on
stems. The method of application is by placing the eyelashes
in-between the two brushes, and squeezing the brushes together.
Aside from being difficult to do, this method does not yield two
separate zones of bristle density.
[0011] U.S. patent application Ser. No. 2003084913 shows two
mascara brushes twisted around each other; these twisted mascara
applicators will not provide one clear zone for the lashes to
enter, thus giving volume, and another giving separating. Since the
bristles from both brushes are randomly intermingled, where the
bristles are, it will act like one brush, without having zones of
different fiber density. Also this brush is different from the
present invention because it states that the cores of the brushes
are separated at a distance, where in the present invention, the
cores of the brushes are connected.

DETAILED DESCRIPTION OF THE INVENTION
[0019] As show in FIG. 1, this invention consists of two spiral
mascara brushes connected along the length of their metal core.
This connecting of 2 mascara brushes along the length of their
cores yields 3 different zones of the dual brush. The zone of the
dual brush (15) where there are only bristles from brush A, the
zone of the dual brush (16) where there are only bristles from
brush B, and the zones of the dual brush where there are bristles
intermingling (14) from brush A and B. Zones where there are the
bristles from both brushes will work to give good separating and
combing to the lashes. The zones with the bristles from both A and
B will have a relatively higher bristle density of fibers with
respect to zones where there are only bristles from one of the
mascara brushes. The mascara brushes A and B may, but need not be
identical. If they are not identical this would create 3 different
zones on the mascara brush corresponding to 3 different types of
application characteristics. In one embodiment brush A has bristles
of 3 mils which do an excellent job of coating the lashes and brush
B has bristles of 11 mils which do an excellent job of separating
the lashes. The users would pass both these zones across her
eyelashes to get the benefits of both types of bristles in one
stroke.
[0020] In another embodiment of this invention, the two twisted
wire brushes that make up this invention would be identical,
creating 2 different zones of the mascara brush, one with a
relatively low density of fibers. The zone with the relatively low
density of fibers would apply a rich coat of mascara to the lashes.
The zones where the brushes intermingle would have a relatively
higher density of fibers, thus, combing and separating well the
lashes.
[0021] One more advantage of this invention is that it facilitates
a way to make a mascara brush with 2 different lengths of fibers.
The longer fibers help in combing the lashes while the shorter
fibers help in applying the mascara on the lashes. Many inventions
have shown way of producing a brush with fibers of different
length, however the process to make these brushes have always been
more complicated than use two brushes connected lengthwise along
their perspective lengths.
[0022] The foregoing should be taken as merely illustrative of the
present invention rather than limiting thereof. The scope of
protection that is sought is set forth in the claims that
follow.
