Abstract

A cosmetic applicator capable of stably applying a cosmetic even when the cosmetic contains large particles. A cosmetic applicator includes a barrel, a brush made of bundled fibers and provided in front of the barrel, a cosmetic accommodation portion arranged in a space behind the barrel, a guide that guides a cosmetic from the cosmetic accommodation portion to the brush, a collector that has a comb-shaped outer circumferential surface and that is disposed inside the barrel and at an outer circumferential portion of the guide, and a front barrel supporting the brush at a front portion of the barrel. A capillary force of the guide is 50 to 200 (mm) (as measured using purified water in an environment of 25° C.). (B)/(A) is 0.8 or greater, where (A) (mg) is an amount of cosmetic liquid discharged for 1 (m), and (B) (mg) is an amount of cosmetic liquid discharged for 1 (m) after 30 (m).

First claim

The invention claimed is:

1. A cosmetic applicator comprising:
a barrel;
a brush made of bundled fibers and provided in front of the barrel;
a cosmetic accommodation portion arranged in a space within the barrel;
a guide configured to guide a cosmetic from the cosmetic accommodation portion to the brush;
a collector that has a comb-shaped outer circumferential surface and that is disposed inside the barrel and at an outer circumferential portion of the guide; and
the barrel supporting the brush at a front portion of the barrel,
a capillary force of the guide being 50 to 200 (mm) (as measured using purified water in an environment of 25° C.), and
(B)/(A) being 0.8 or greater, where (A) (mg) is an amount of cosmetic liquid discharged for 1 (m), and (B) (mg) is an amount of cosmetic liquid discharged for 1 (m) after 30 (m).

2. The cosmetic applicator according to claim 1 , wherein a maximum diameter of the brush excluding a flange portion is 2.5 to 4 (mm), a ratio of a length (L1) of the brush protruding from the barrel toward a front direction to a total length (L) of the brush, or L1/L, is 0.6 to 0.9, and the total length (L) of the brush is 15 (mm) or less.

3. The cosmetic applicator according to claim 1 , wherein a front end surface of the guide is positioned in front of a front end surface of the barrel, and a cross-sectional area of a space inside the brush is 15(%) or greater of a cross-sectional area of the brush.

4. The cosmetic applicator according to claim 1 , wherein
the cosmetic applicator is adapted for a cosmetic, and
the cosmetic comprises at least glitter particles having a long axis length of 10 to 30 (μm), glitter particles having a long axis length of 50 to 80 (μm), and water.
