Description
FIELD OF THE INVENTION
[0001] The present invention relates to an applicator for cosmetic
products. More specifically, the invention relates to a mascara
brush with a fan tip that facilitates both general and precise
application of mascara.
BACKGROUND OF THE INVENTION
[0002] The application of cosmetics to enhance one's appearance is
an age-old practice. Accordingly, different kinds of cosmetics have
been developed for enhancing particular physical features, such as
mascara, which is used to lengthen, thicken, and color one's
eyelashes. Typically, these kinds of liquid-type cosmetics are
applied with a brush.
[0003] Mascara brushes are generally well known in the art.
Typically, they comprise a series of bristles connected to an
applicator rod, which extends from the underside of a bottle cap.
When not in use, the rod and bristles are inserted into an opening
in a bottle containing the mascara, and the cap closes the bottle.
There is usually a wiper in the neck of the bottle, through which
the rod extends when the bottle is closed, such that the bristles
are immersed in the mascara.
[0004] The mascara brush must perform several functions. First, the
brush must accumulate mascara within the bottle, and carry the
mascara through the wiper, which removes the excess mascara from
the bristles. The mascara brush must then apply the mascara to the
eyelashes, and preferably, be capable of curling or lifting the
eyelashes. The mascara brush must also be capable of combing and
separating the eyelashes, as well as spreading the mascara
relatively evenly thereon. In all these functions, the brush is
desirably comfortable for the consumer to use.
[0005] A typical mascara brush for achieving these various
functions comprises a plurality of bristles mounted to a helically
twisted wire. Such twisted wire brushes conventionally are
manufactured by disposing a plurality of individual lengths of
bristles transverse to and between substantially parallel, slightly
spaced-apart thin metal wire lengths, such that the wire lengths
generally bisect the filament lengths at their midpoints. Most
typically, the parallel wire lengths comprise two substantially
equal leg segments formed from bending a single length of wire into
a U-shaped configuration. The wire lengths are then twisted
together to form a helical core, causing the bristles disposed
between the wires to be clamped therebetween at about their
midpoints. In this twisting and clamping, the segments of the
bristles on either side of the clamped midpoint are caused to flare
radially outward from the core and thereby form an elongate bristle
brush portion of generally circular cross-section. Examples of this
process are described, for instance, in U.S. Pat. No. 6,481,445 to
Miraglia and U.S. Pat. No. 5,551,456 to Hartel.
[0006] Generally, a large number of these radially-projecting
bristles spiral along the length of the wire, thereby facilitating
the collection and transfer of a substantial amount of mascara from
the bottle to the eyelashes. Additionally, mascara is typically
highly viscous, and thus, tends to clump when applied to eyelashes.
These clumps of mascara are usually combed out as a finishing step
during the application process, thereby requiring a relatively open
bristle array in order to create a "comb-like" brush that is well
suited for combing out the clumps and properly separating the
lashes. However, the conventional arrangement of many projecting
bristles along the length of the brush can make it difficult to
perform more precise applications, such as may be required in order
to apply mascara to the smaller, bottom lashes, in order to reach
the corners of the lashes, and to perform general touch-up.
[0007] What is desired, therefore, is a mascara brush having a
twisted wire stem and outwardly extending bristles that can collect
and carry a satisfactory amount of mascara without repeated
reintroductions of the brush into the mascara bottle. What is also
desired is a mascara brush that provides good combing and
lash-lengthening effects. What is further desired is a mascara
brush with the above features that facilitates precise application
of the mascara where necessary.
SUMMARY OF THE INVENTION
[0008] Accordingly, it is an object of the present invention to
provide a mascara brush with enough bristle surface area to collect
a large amount of mascara from a bottle and carry it to one's
eyelashes.
[0009] It is a further object of the present invention to provide a
mascara brush with enough bristle rows along the length of the
brush to provide an adequate combing ability.
[0010] It is yet another object of the present invention to provide
a mascara brush that enables one to apply mascara to small and hard
to reach parts of one's eyelashes.
[0011] It is still another object of the present invention to
provide a mascara brush that enables one to precisely touch-up the
mascara.
[0012] In order to overcome the deficiencies of the prior art and
to achieve at least some of the objects and advantages listed, the
invention comprises a method for applying mascara, including
providing a mascara container having mascara therein, forming a
wire into approximately a U-shape having two leg segments,
positioning a plurality of bristles between the two leg segments of
the U-shaped wire, twisting the wire to produce a helical wire core
having a plurality of bristles extending radially therefrom,
bending an end of the wire core to produce a fan of bristles
fanning out therefrom, and inserting the wire core into the mascara
container to collect mascara.
[0013] In some of these embodiments, the approximately U-shaped
wire has a base segment, and the step of twisting the wire
comprises forming the base segment into a wire loop at the distal
end of the brush.
[0014] In another embodiment, the invention comprises a method for
applying mascara, including the steps of providing a mascara brush
comprising a twisted wire core having a plurality of bristles
extending radially therefrom and a distal end, bending the distal
end of the brush to produce a fan of bristles fanning out
therefrom, and collecting mascara on the plurality of bristles.
[0015] In yet another embodiment, the invention comprises a mascara
applicator, including a container cap for closing a mascara bottle,
an elongated member extending from the cap, the member having a
core and a distal end, a first plurality of bristles radially
extending from the core, and a second plurality of bristles fanning
out from the distal end of the elongated member.
[0016] In still another embodiment, the invention comprises a
mascara applicator, including a handle, and a twisted wire core
connected to the handle, the wire core having a first plurality of
bristles extending radially therefrom, a longitudinal axis, and a
distal end, where the distal end of the core is bent relative to
the longitudinal axis such that a second plurality of bristles fan
out from the distal end of the core.
[0017] In certain embodiments, the second plurality of bristles fan
out along a plane substantially parallel to the longitudinal axis
of the core. Preferably, the distal end of the core is bent
approximately one hundred and eighty degrees so that the second
plurality of bristles fan out along an arc. In some of these
embodiments, the bent portion of the core comprises between one to
eight, and more preferably, one to four turns of the twisted wire
core.

DETAILED DESCRIPTION OF THE INVENTION
[0021] The basic components of one embodiment of a mascara
applicator in accordance with the invention are illustrated in FIG.
1. As used in the description, the terms "top," "bottom," "above,"
"below," "over," "under," "above," "beneath," "on top,"
"underneath," "up," "down," "upper," "lower," "front," "rear,"
"back," "forward" and "backward" refer to the objects referenced
when in the orientation illustrated in the drawings, which
orientation is not necessary for achieving the objects of the
invention.
[0022] A mascara applicator brush 10 comprises a handle end 12 and
a brush end 14. The brush 10 includes an elongated member
comprising a central, twisted wire core 18 with a longitudinal axis
20, and a helical array of regularly disposed bristles 24 retained
by the twisted wire core 18 in the manner further described below.
The core 18 is connected to a rod 26, which is, in turn, connected
to a cap 28 for a mascara bottle 30. The brush end is inserted
through an opening 32 in the bottle 30, past a wiper 34, in order
to load mascara on the bristles 24.
[0023] The bristles 24 are usually made by cutting short segments
from spools of filaments. The filaments are formed from nylon or
polyester, or another suitable material. The filaments will
typically be circular solids in cross-section, but alternatively,
may have non-circular cross-sectional shapes, such as ovals,
square, rectangular, or polygons (including hexagons), or the
bristles may have voids therein, and thus, the term "diameter" as
used herein to refer to "bristle diameter" is intended to mean the
maximum distance between any of the possible opposite positions on
the outer surface of a bristle filament.
[0024] As illustrated in FIG. 2, the wire core 18 is made by
forming wire into a "U" shape having leg segments 40 and 42 and a
tip 44. The plurality of bristles 24 are placed between the leg
segments 40 and 42, and these leg segments are then twisted around
each other to clamp the bristles 24 therebetween at approximately
the midpoints of the bristles 24. As a result of this twisting and
clamping, the ends of the bristles 24 extend radially from the wire
core 18 about the longitudinal axis 20 in a helical or spiral
manner. Accordingly, a first plurality of bristles 52 extends along
a substantial portion of the wire core 18, thereby providing a
sufficient surface area for transporting and applying large amounts
of mascara. After the bristles 24 are mounted to the wire core 18,
the bristles 24 can be trimmed so that the brush 10 has any desired
shape, such as, for example, cylindrical, tapered, conical, curved,
etc. If desired, the ends of the bristles 24 may be processed by
grinding, heating, or other techniques.
[0025] Typically, the wire of the twisted wire core 18 has a
diameter of about 0.028 inch, and the core 18 has a pitch of about
0.04-0.10 inch to about 0.250 inch. The pitch P is the linear
distance along the axis 20 of twisted wire core 18 from the center
60 of a wire segment to the center 62 of that wire segment 40 after
it has twisted through 360 degrees.
[0026] Typically, the rod 26 may have a diameter in the range of
about 0.065 inch to 0.250 inch, and more specifically, about 0.075
inch to 0.125 inch. As shown in FIG. 3, the twisted wire core 18
has a first end 45 that can be attached to rod 26.
[0027] The bristle density per turn may be selected from a range of
between about 10-65 bristles per turn. The preferred bristle
density will be dependent on the bristle diameter, and, to a
degree, on the hardness of the polymer used in making the bristles.
The preferred bristle diameter will range between 0.003 inch and
0.012 inch, most preferably about 0.004 to 0.006 inch.
[0028] In the preferred embodiment there are between 18-22 rows of
bristles that are twisted into the wire core 18. The section of the
wire core 18 containing the bristles preferably comprises about
20-28 turns, most preferably about 24 turns.
[0029] The end section 46 of the twisted wire core 18 is bent over
onto itself, which results in a fan tip section 54 comprising a
plurality of bristles fanning out from the end section 46. The fan
tip section 54, which is separate and angularly offset from the
rest of the bristles extending along the length of the twisted wire
core 18, should enable the user to easily perform precise
application of the mascara.
[0030] In certain advantageous embodiments, the wire is bent
approximately one hundred and eighty degrees, and the end section
46 includes between one to eight turns of the wire core 18, and
most preferably the end section 46 includes between one to four
turns of the twisted wire core 18 between the bending point and the
bent end 48 of end section 46
[0031] The bent over end section 46 of the wire core 18 creates a
fan tip section at the distal end of the brush 10. The fan tip
section 54 preferably defines a 180 degree arc extending in a plane
which is parallel to the axis of the wire core 18. However, the
bent over section 46 may be bent at other angles so that the fan
tip section 54 extends in other directions somewhere between and
including planes which extend parallel to, and perpendicular to,
the longitudinal axis of the brush 10. The fan tip section may also
be somewhat less than a 180 degree arc.
[0032] It should be understood that the foregoing is illustrative
and not limiting, and that obvious modifications may be made by
those skilled in the art without departing from the spirit of the
invention. Accordingly, reference should be made primarily to the
accompanying claims, rather than the foregoing specification, to
determine the scope of the invention.
