Abstract

Provided is a cosmetic applicator having an applying part at the tip end and a container containing liquid cosmetic to be applied through the applying part. A tip-most portion of the applying part is disposed at a position deviated from an axis of the applying part and an angle θ between a line perpendicular to the axis and a side ridge line at applying part end ranges from 10° to 60°, a circular flange is formed at a rear end of the applying part, a projecting length of the applying part from a front barrel ranges from 5 to 8 mm, a ratio of a major and minor axis Y, X of an opening is Y:X=1.3 to 2:1, and when A and B respectively denote an applied area at deformation load of 0.01 N and that at 0.1 N, A<B<3A is satisfied.

First claim

What is claimed is:

1. A cosmetic applicator, comprising:
an applying part at a tip end of the applicator;
a front barrel, wherein the tip end of the applicator is located on the front barrel; and
a containing part containing liquid cosmetic that is to be applied through the applying part,
wherein
a tip-most portion of the applying part is disposed at a position deviated from an axis of the applying part and an angle θ between a line perpendicular to the axis and a side ridge line of the applying part ranges from 10° to 60°,
a circular flange is formed at a rear end of the applying part,
a projecting length of the applying part from a tip end of the front barrel ranges from 5 to 8 mm,
a ratio of a major axis Y and a minor axis X of an opening, being located at the tip end of the front barrel in the applying part, is Y:X=1.3 to 2:1, and
when A and B respectively denote an applied area at deformation load of 0.01 N and an applied area at deformation load of 0.1 N both measured from the tip-most portion of the applying part, A<B<3A is satisfied.

2. The cosmetic applicator according to claim 1 , wherein the applying part is formed of a fiber bundle obtained by bundling a plurality of fibers, and a tip end part of each fiber has a curvature.

3. The cosmetic applicator according to claim 1 , wherein the applying part is formed of a fiber bundle obtained by bundling a plurality of fibers, and a variation in length in a tip end of each fiber with respect to the side ridge line of the applying part is within a range of 1 mm.

4. The cosmetic applicator according to claim 1 , wherein the applying part is formed of a fiber bundle obtained by bundling a plurality of fibers with a small outer diameter and a plurality of fibers with a large outer diameter, and wherein there are more of the fibers with small outer diameter than the fibers with large outer diameter.

5. The cosmetic applicator according to claim 1 , wherein a viscosity of the liquid cosmetic is within a range of 1.5 mPas to 70 mPas.
