## Title
Brush for application of mascara or the like

## Abstract

There is provided a brush for application of mascara or the like, comprising a brush core and bristles held on the brush core, wherein each of the bristles is in a shape of ring such as circle or ellipse of two-dimensional or three-dimensional planar or spatial curve and is held on the brush core in such a manner that a face of the bristle is at an angle of 0° to 90° with a longitudinal axis of the brush core. The brush, such as mascara brush makes it possible to apply quickly, simply and beautifully mascara even in a large amount onto the eyelashes by gently stroking onto the eyelashes.

## Background
TECHNICAL FIELD
The present invention relates to a brush for application of cosmetics such as mascara.
BACKGROUND ART
In conventional mascara brushes, concavity and convexity parts are formed on the bristles thereof in order to make a large amount of mascara adhere on the bristles (for example, Japanese Patent Laid-open No. 2002-129477).
DISCLOSURE OF INVENTION
Problem to be Solved by the Invention
An object of the present invention is to provide mascara brushes with which the amount of mascara to be adhered on the bristles is increased, and mascara can be applied onto the eyelashes quickly and simply by applying a large amount of mascara onto the eyelashes just like gentle stroking.
As the conventional mascara brushes in which a plurality of straight bristles are held on the brush core have free ends of the bristles outwardly and the free ends are generally angular, it is difficult to stroke the eyelashes gently with the mascara brushes. In addition, when the number of the straight bristles is increased in order to increase the amount of mascara to be adhered on the bristles, the free ends are further angular, therefore it becomes still difficult to stroke the eyelashes gently with the mascara brushes.
In case where the mascara brush disclosed in Japanese Patent Laid-open No. 2002-129477 is used, it is easy to make mascara adhere on the bristles thereon, but it is very difficult to transfer the mascara onto the eyelashes.
Means for Solving the Problem
The brush for application of mascara or the like according to the present invention comprises a brush core and a plurality of bristles held on the brush core, in which each of the bristles is in a shape of ring such as circle or ellipse, that is, the bristle is in a shape of a two-dimensional planar curve or a three-dimensional spatial curve, and in which each of the bristles is held on the brush core in such a manner that a face of the planar curve or spatial curve of the ring-shaped bristle is at an angle of 0° to 90° with a longitudinal axis of the brush core, that is, the ring-shaped face of the bristle is from in an identical direction (parallel direction) to a longitudinal axis of the brush core, to in the direction perpendicular to the longitudinal axis of the brush core.
EFFECT OF THE INVENTION
As a large amount of mascara is adhered in a shape of film to the bristles in a shape of ring such as circle or ellipse in the brush for application of mascara or the like according to the present invention, it is possible to apply a large amount of mascara on the bristles. Therefore, the mascara brush according to the present invention makes possible to simply apply a large amount of mascara onto the eyelashes by allowing the film of mascara adhered to the bristles to break with the eyelashes. When the bristles of the brush are rotated around the brush core, the eyelashes are not strongly rubbed with edges of free ends of the bristles but they are gently stroked with the bristles in a shape of ring such as circle or ellipse, because the bristles are in a shape of ring such as circle or ellipse. Consequently, according to the present invention, it is possible to apply quickly, simply and beautifully mascara even in a large amount onto the eyelashes.
