Mascara brush
Abstract
In a mascara brush with a plurality of bristles being fixed
between two intertwisted wire sections, standing out therefrom on
both sides, and with the bristles having a noncircular cross
section, it is provided, with a view to improving the mascara
transfer properties, that, proceeding from conventionally extruded
fibers, at least two of these fibers are connected to each other
lengthwise in the form of lines or points.

Claims
What is claimed is:
1. A mascara brush with a plurality of bristles being fixed between
two intertwisted wire sections, standing out therefrom on both
sides, and with the bristles having a noncircular cross section,
wherein, proceeding from conventionally extruded fibers (1, 2), at
least two of these fibers (1, 2) are combined lengthwise in the
form of lines or points.
2. A mascara brush according to claim 1, wherein the fibers (1, 2)
which are connected to each other have a varying diameter.
3. A mascara brush according to claim 1, wherein at least one fiber
(2) is wavy as compared to the other fiber (1) and wherein the
fibers (1, 2) are connected to each other by points in the vicinity
of the concavities (7).
4. A mascara brush according to claim 1, wherein at least part of
the fibers (1, 2) are hollow fibers (6) or have a noncircular cross
section.
5. A fiber for a mascara brush according to one of claims 1 to 4.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a mascara brush with a plurality of
bristles being fixed between two intertwisted wire sections,
standing out therefrom on both sides, and with the bristles having
a noncircular cross section.
[0003] 2. Background Art
[0004] It is known in mascara brushes to use bristles of cloverleaf
cross section or bristles having at least one longitudinal
capillary groove and in this way to obtain capillary space for
increased mascara absorption and transfer capacity. Furthermore, it
has been specified to use circular bristles of varying cross
section.
[0005] So as to obtain brushes with especially fine bristles in the
finished product which would be difficult to treat because of their
inferior thickness, it has become known to compose bristles of
individual sectors so that an overall circular cross section
results during the manufacture of the brush. As soon as the
bristles are fixed between the intertwisted wires, the bond of the
individual sectors is dissolved by the aid of a solvent so that
then bristles of a very small cross section are obtained from these
individual sectors, these bristles fanning out conically from one
and the same spot where the originally round bristle had been
squeezed between the wire sections (cf. U.S. Pat. No.
5,355,547).
SUMMARY OF THE INVENTION
[0006] It is an object of the invention to embody a mascara brush
or, respectively, to create a bristle for a mascara brush which
enable optimum combing and transfer behavior to be realized.
[0007] According to the invention, this object is attained in that,
proceeding from conventionally extruded fibers, at least two of
these fibers are combined lengthwise in the form of lines or
points.
[0008] This enables nearly any cross-sectional configuration to be
produced, in particular in the light of the further possibility of
combining fibers of varying diameters. The bristles thus created
exhibit in particular a high capillarity.
[0009] The fibers may be connected to each other lengthwise in the
form of continuous lines. By alternative, point combination of the
fibers may be provided, in which case it may be advantageous for at
least one fiber not to be parallel to another fiber, but to be
approximately wavy, point connection then being produced only in
the concavities. In this way, tiny longitudinal eyes will form
between two fibers of this type, in which to store mascara.
[0010] In keeping with another embodiment, it may be provided that
at least part of the fibers are hollow fibers or fibers of
noncircular cross section.
[0011] The design according to the invention also helps attain a
spreading effect and a uniform distribution of the tips.
[0012] Connecting the fibers to each other may be implemented by
all the types of connection systems that are customary in plastics
engineering, in particular thermally, chemically, by ultrasound
welding, etc.
[0013] Details of the invention will become apparent from the
ensuing description of preferred exemplary embodiments, taken in
conjunction with the drawing.
BRIEF DESCRIPTION OF THE DRAWING
[0014] FIG. 1 is a cross sectional view of a first embodiment;
[0015] FIG. 2 is a lateral view of details of this embodiment
comprising two fibers that are connected to each other;
[0016] FIG. 3 is a section through a second embodiment comprising
four fibers which are connected to each other;
[0017] FIG. 4 is a partial lateral view of the embodiment of FIG.
3;
[0018] FIG. 5 is a view of the section through an embodiment in
which a central hollow fiber is combined with two solid fibers;
[0019] FIG. 6 is an illustration of another embodiment in which
eyes are formed in the longitudinal direction between two fibers
that are united by point connection; and
[0020] FIG. 7 is an illustration corresponding to FIG. 6 with three
fibers being combined.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] In the embodiment seen in FIGS. 1 and 2, a first fiber 1 of
greater diameter is connected to a second fiber 2 of smaller
diameter along a line 3, capillary grooves 4, 5 being formed on
both sides of this line 3.
[0022] In the embodiment according to FIGS. 3 and 4, a central
fiber 1 of greater diameter is combined with three fibers 2 of
smaller diameter.
[0023] The cross-sectional view of FIG. 5 illustrates that a
central hollow fiber 6 of greater cross section is connected to two
diametrically opposed solid fibers 2 of smaller cross section.
[0024] FIGS. 6 and 7 illustrate examples in which a single fiber 2
or two fibers 2 of inferior cross section are connected to a
thicker fiber 1 only at discrete welding spots 7 with the thinner
fiber 2 being wavy for eye type inter-spaces 8 to form between two
successive welding spots 7, creating the possibility of reserve
capillarity.
