Abstract

The present invention provides a cosmetic material applying container that provides comfortable use feeling and facilitates drawing a narrow line. A cosmetic material applying container includes a leading end portion which discharges a cosmetic material and is formed of a soft material. The leading end portion has a flat shape and an edge shape. A top end surface of the leading end portion constitutes an applying surface, and the leading end portion has a tapered shape. The distal end side of the leading end portion is formed in a sharp shape. The applying surface includes a distal end where a vertex position constitutes a sharp portion. The applying surface includes a concave part depressed toward a base end side in a side view at the distal end side.

First claim

What is claimed is:

1. A cosmetic material applying container comprising:
a leading end portion for discharging a cosmetic material filled in a filling region inside of the container, the leading end portion being formed of a soft material, wherein
the leading end portion is formed as an edge shape in a side view along a shorter axis direction while an outer shape of a transverse cross section is formed as a flat shape, a top end surface of the leading end portion constituting an applying surface, the leading end portion having a tapered shape with a shorter length of the shorter axis toward a distal end side,
the distal end side of the leading end portion is formed in a sharp shape where one side in a longer axis direction is sharpened at an acute angle viewed from the distal end side, and the applying surface includes:
a distal end where a vertex position is formed, the vertex position constituting a sharp portion of the distal end of the leading end portion;
a concave part at the distal end side, the concave part being depressed toward a base end side in the side view;
a convex part at the base end side of the concave part, the convex part bulging toward the distal end side in the side view;
a curved surface shape that extends in an S-shape in the side view by smoothly connecting the concave part and the convex part to each other; and
a discharge port for discharging cosmetic material that is provided continuously over the concave part and the convex part.

2. The cosmetic material applying container according to claim 1 ,
wherein the shape of the leading end portion is three-dimensionally formed by:
constituting a flat column body by a flat base end shape and a flat distal end shape, the distal end shape being disposed at a distal end side with respect to the base end shape;
setting a curved line on a planar surface that includes a longer axis of the base end shape and a longer axis of the distal end shape in the column body, the curved line being inclined from one intersecting point between an outer edge of the distal end shape and the longer axis of the distal end shape toward the base end side, the curved line having a depressed shape at the distal end side, the depressed shape being depressed toward the base end side; and
cutting the column body with a cut surface passing through the curved line.
