Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an applicator for liquid cosmetics such as mascara used for eyelashes and hair.

[0002]

2. Description of the Related Art Conventionally, there has been known an applicator for applying liquid cosmetics such as mascara formed in a spiral brush form by spirally winding a bundle of hairs between two wires. Although such a spiral brush can be easily manufactured, it has a drawback in that it is difficult to apply the cosmetic uniformly and the eyelashes stick to each other. In addition, there are coating parts formed in a screw shape or a comb shape, but these have the disadvantage that the applied amount of the cosmetic is too large.

[0003]

SUMMARY OF THE INVENTION According to the present invention, when applying a liquid cosmetic to eyelashes, an appropriate amount of application can be achieved very easily, uniform application is possible, and the eyelashes are dispersed without sticking to each other. I want to be able to do it.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the means adopted by the present invention is characterized in that a brush portion is formed by electrostatically implanting fibers into a core material. The fiber may be a mixture of two or more fibers having different thicknesses and lengths.

[0005] The core is made of metal or synthetic resin, and may be a bar made of twisted stainless steel wires or an aluminum bar.

[0006] The fibers are 6 to 20 denier thick and 1 to 1 denier.
It is characterized by being made of a fiber having a length of 2 mm.

[0007] The core material is 6 denier thick and 1.75 mm long
The brush portion is formed by electrostatically flocking the fibers.

[0008] The core material is 20 denier in thickness and 1.5 mm in length.
The brush portion is formed by electrostatically flocking the fibers.

The core material is 15 denier thick and 1.5 mm long
And a brush having a thickness of 6 denier and a length of 1.75 mm was mixed and subjected to electrostatic flocking to form a brush portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. The applicator of the present invention is characterized in that fibers are electrostatically implanted into a core material to form a brush. As the core material, metals such as stainless steel and aluminum, and synthetic resins such as polypropylene, polyacetal, and nylon can be used. The fibers to be planted are one or two of 6 to 20 denier in thickness and 1 to 2 mm in length.
More than one kind of fiber is preferred. An adhesive is applied to the surface of the core material by a spray method, and thereafter, the fibers are electrostatically adsorbed and planted.

FIG. 1 shows a core material (1) obtained by twisting stainless steel wires, and an adhesive (2) is applied to the tip of the core material.
Fibers (3) having a desired thickness and length are electrostatically adsorbed and formed on a brush portion. The adhesive (2) was applied twice: undercoating and overcoating. FIG. 2 shows a metal rod as a core material. FIG. 3 shows a core material made of a synthetic resin, which is formed in a special form. FIGS. 4 to 7 show various examples of the cross-sectional shape of the core material, and any shape can be adopted, thereby changing the appearance and increasing the commercial value. Table 1 shows the relationship among the fiber thickness, fiber length, and brush diameter. Table 2 shows the evaluation of the usability with cosmetics based on the thickness and length of the fiber, and the circled portions have the optimum usability. From Tables 1 and 2, it was found that fibers having a denier of 30 denier or more were unsuitable because the diameter of the brush portion was too large.

[0012]

[Table 1]

[0013]

[Table 2]

Next, Table 2 shows the optimum usability 6
Actual makeup for five types of brushes with three different thicknesses of denier, 15 denier, and 20 denier, and formed with brushes of three different lengths of 1.25 mm, 1.5 mm, and 1.75 mm The usability when the coating was applied was evaluated.
Table 3 shows the results. The cosmetic A is a volume and curl type mascara, and the cosmetic B is a natural type mascara. From Table 3, 1.75m at 6 denier
m brushes, 1.5 denier brushes at 15 deniers and 1.5 mm brushes at 20 deniers showed good usability, in particular, 6 denier 1.75 mm brushes.

[0015]

[Table 3]

Therefore, 6 denier, 1.75 mm brush and 20 denier, 1.5 denier which showed good usability in Table 3 were shown.
For the two types of brushes, mm brush, volume & curl type mascara with 20 denier, 1.5 mm brush, and natural & curl type mascara with 6 denier, 1.75 mm brush Was evaluated for more than a dozen women in their twenties and women in their forties. As a result, the mascara brush of the present invention was evaluated as having a soft and smooth feeling of use, a delicate finish that does not limp the cosmetic, easy application, and a high curling effect.

Although the brush described above is made of a single fiber, a brush portion may be formed by mixing and electrostatically adsorbing two or more kinds of fibers having different thicknesses and lengths. As the fibers to be used, for example, two kinds of fibers having a thickness of 15 denier and 1.5 mm in length, and a fiber of 6 denier and 1.75 mm in length, or 15 denier and 1.
75mm fiber, 6 deniers thick, 1.75mm long 2
A mixture of seed fibers was preferred. By mixing two or more types of fibers having different thicknesses and lengths, dense flocking was achieved, so that the adhesive strength of the fibers was improved and fiber drop was small.

[0018]

According to the present invention, it is possible to obtain a cosmetic applicator which applies a cosmetic evenly, has no fear that eyelashes stick together, has a soft and smooth feeling of use, is easy to apply, and has a high curling effect. Can be done.
