Claim 9:
10. A liquid cosmetic material container comprising:
a sleeve that includes a storage chamber that stores a liquid cosmetic material therein;
a bead member that is disposed at a front end of the sleeve, has a through hole extending in an axial direction of the liquid cosmetic material container and configured to store a brush in the through hole; and
a relay core that is configured to connect the brush and the storage chamber, enter the brush, and send the liquid cosmetic material in the storage chamber to the brush,
wherein a rear portion of the through hole has a first cross sectional area, a front portion of the through hole has a second cross sectional area which is smaller than the first cross sectional area, and a cross sectional area of the through hole is gradually changed from the first cross sectional area to the second cross sectional area,
when viewed in the axial direction, a shape of the rear portion of the through hole is formed in a first corrugated shape including first concave portions and first convex portions that are alternately disposed and connected to have a first annular shape, the brush comes into contact with the first convex portions of the first corrugated shape, and a first gap is formed between each of the first concave portions of the first corrugated shape and an outer face of the brush,
when viewed in the axial direction, a shape of the front portion of the through hole is formed in a second corrugated shape including second concave portions and second convex portions that are alternately disposed and connected to have second annular shape, wherein the second annular shape is a polygonal shape in which the second convex portions are sides of the polygonal shape and the second concave portions are vertexes of the polygonal shape, and wherein the brush comes into contact with the second convex portions of the second corrugated shape, and a second gap which is smaller than the first gap is formed between each of the second concave portions of the second corrugated shape and the outer face of the brush,
a concave curvature of one of the second concave portions is smaller than that of a corresponding one of the first concave portions, and
a convex curvature of one of the second convex portions is smaller than that of a corresponding one of the first convex portions.
