Abraded spiral wound brush
Abstract
In a spiral wound brush for applying mascara and similar
hair-streaking cosmetic products, the present invention replaces
the sharply clipped ends common to the synthetic fibers typically
employed with synthetic fibers having raggedly formed bristle ends
for enhancing the pick up of the cosmetic product and for applying
it thereafter with a softer feel.

BACKGROUND OF THE INVENTION
[0003] 1. Field of the Invention
[0004] This invention relates to spiral wound brushes for applying
mascara and similar face-color cosmetic products, in general, and
to a construction which enhances pick up of the cosmetic product
and which provides a more softer feel in its application.
[0005] 2. Description of the Related Art
[0006] As will be appreciated by those skilled in the art, spiral
wound brushes for applying mascara and similar hair-color cosmetic
products commonly employ synthetic fiber bristles having sharply
clipped ends. Whether the fibers be extruded as solid, or as hollow
cylindrical flexible tubes, their sharply clipped ends limit their
ability to pick up the cosmetic product to begin with, and the feel
one experiences when the product is applied and laid down. As will
become clear from the following description, the present invention
promotes the ability to provide a softer feel and to enhance the
transfer of cosmetic product from its package to the user by
providing synthetic fiber bristles with characteristics more akin
to those exhibited by natural animal hair.
SUMMARY OF THE INVENTION
[0007] Thus, and in accordance with the invention, the synthetic
fibers of the spiral wound brush offering these improvements are
provided with raggedly formed bristle ends rather than the angular
geometric presentation which typifies clipped extruded synthetic
fibers. Such improvements will be appreciated whether the brush
utilizes hollow or solid synthetic fibers, whether the fibers be
polyamide resins or extruded from other polymers, and whether the
fibers be used for mascara or other hair-coloring cosmetic product,
picked up from a reservoir and transferred to apply.
[0008] As will be described, a preferred embodiment of the
invention gives this ragged formation to the bristle ends by
employing an abrasive medium either perpendicularly or laterally to
the fibers. Utilizing a rotating cylindrical abrading wheel, for
example, this abrades the ends to produce an appearance similar to
that of a higher-end paint brush where animal bristles are utilized
in the picking up and smoothly laying down of paint. In this
embodiment to be described, moreover, the spiral wound brush is
provided with a solid or hollow, synthetic polyamide fiber abraded
by an aluminum oxide or Carborundum wheel. The fibers in spiral
wound brushes such as those employed for mascara application and
streaking one's hair have a secondary purpose: combing and
separating the lashes or hair. Since the treatment described herein
only affects the extruded ends, there is no deterrent to this
function. Enhanced results could also be had by using certain
corrosive organic or inorganic chemical exposure to the fibers.
Such alternative arrangement, however, would require an additional
expense for removal or neutralization of any corrosive chemicals
that might be employed to eliminate the harmful results that might
possibly arise from any residue coming close to a user's eyes.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] These and other features of the present invention will be
more clearly understood from a consideration of the following
description, taken in connection with the accompanying drawings, in
which:
[0010] FIG. 1 is an illustration of a spiral wound brush as might
be utilized to apply cosmetics--and, more particularly, mascara and
similar hair-streaking cosmetic products;
[0011] FIG. 2a illustrates the typical clipped synthetic fiber
bristle brush strands as typify the present manufacture of spiral
wound brushes of this type; and
[0012] FIG. 2b is an illustration of the synthetic fiber bristle
brush strands as constructed in accordance with the teachings of
this invention.
DETAILED DESCRIPTION OF THE INVENTION
[0013] Referring to the Drawings, the spiral wound brush of FIG. 1
includes a handle 10 and pluralities of strands of bristle fibers
12 outwardly extending from its core 14 at regular intervals
angularly in a helical orientation. (For purposes of clarity, only
two such series of strands 12 are shown.) FIG. 2a is a magnified
illustration of the strands 12 as characterize present spiral wound
brush constructions in which the synthetic fibers employed exhibit
sharply clipped ends 16 commonly resulting from the fiber trimming.
As will be understood, this follows whether the fibers be extruded
as solid, or as hollow, cylindrical flexible rods. Ten such strands
are shown in FIG. 2a, but fewer or greater numbers may be utilized
depending upon the manufactured design.
[0014] As previously mentioned, the present invention follows from
the recognition that natural animal hair picks up more material in
any given utilization, and lays it down more evenly and softly in
application--and that this results because of their absence of
sharply clipped ends. With their random orientation and the
modification of the present invention, the spiral wound brush
simulates this natural animal hair by providing the bristle ends of
the fibers with a ragged formation, as shown at 18, 20 in FIG. 2b.
In accordance with the invention, this can be had by abrading the
fiber bristles with a rotating cylindrical abrading wheel of design
whose abrasion force is applied either perpendicularly or laterally
against the ends of the bristles. Such forces are indicated in FIG.
2b by the arrows 100 and 101, respectively. (Alternatively,
although not as preferable because of economic and control
drawbacks, and because of the need for taking greater safety
precautions, the ragged appearance to the bristle ends could be had
through corrosive organic or inorganic chemical exposure of the
fibers.)
[0015] In the preferred embodiment of the invention--and more
particularly one which exhibits a great softness of feel and an
ease of transfer of mascara or similar hair-color cosmetic
products--the synthetic fibers of the invention are selected of
polyamide resin. Other synthetic polymer fibers could be employed,
and solid synthetic fibers could likewise be utilized instead of
the preferred hollow synthetic fiber of the invention. In either
event--namely, whether hollow or solid synthetic fibers are used,
and regardless of whether they be polyamide or other polymer
resins--acting on the fiber bristles to give the ragged formation
rather than one of sharply clipped ends provides the benefits of
softer feel of application and enhanced ease of cosmetic product
transference.
[0016] While there have been described what are considered to be
preferred embodiments of the present invention, it will be readily
appreciated by those skilled in the art that modifications can be
made without departing from the scope of the teachings herein. For
at least such reason, therefore, resort should be had to the claims
appended hereto for a true understanding of the invention.
