Abstract

PROBLEM TO BE SOLVED: To eliminate the need to apply nail enamel several times to prevent uneven application by setting the width of the root of a brush part to a specific size. SOLUTION: The root 3 of a brush fastened into a handle 2 is 3 to 10 mm wide, a bristle part 4 is 3 to 12mm wide, and the brush part is preferably 0.5 to 3 mm thick. Since the root 3 of the brush part 1 is wide and the width of the bristle part 4 is also large enough to match the width of the root 3, a sufficient width can be secured even if the brush contains nail enamel. To apply the nail enamel to the nails, the brush part 1 is pressed against the nails; if the enamel is thinly applied, the bristles broaden greatly since the brush part is strongly pressed against the nails; if it is thickly applied, the bristles do not broaden greatly. Thus, the difference among users in the way the enamel is applied is appropriately dealt with to reduce the number of times of application to prevent uneven application.

FIELD OF THE INVENTION The present invention relates to a brush for applying nail enamel.

2. Description of the Related Art Conventionally, a brush has been widely used as an applicator for applying nail enamel. Nail enamel forms a robust coating on the nails to protect them and at the same time give them an aesthetic appearance, making them an important part of modern beauty. Nail enamel is a film-forming component made by mixing nitrocellulose with a resin such as alkyd resin and acrylic resin.
It has a solvent component, a coloring agent consisting of a coloring agent and a pearlescent agent as its main ingredients, has a proper viscosity that is easy to apply to the nails, forms a tough film after drying, and has the property that it can be easily removed with an enamel remover. Have

Two types of conventional brushes for applying nail enamel are known, round brushes and flat brushes, but the width of the tip of each brush is smaller than the width of the nail. That is, a round brush usually has a root of 1.5 mm and a tip of about 3 mm, and a flat brush has a root of 2.7 mm and a tip of about 5 mm. However, since the width of a female thumb is about 10 to 15 mm on average, and even the little finger is about 5 to 8 mm, the range that can be applied at one time with a conventional brush is narrow compared to the area of the nail, and it is necessary to apply it many times. There was a drawback that the applied portion became uneven and the applied portion became uneven.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to eliminate the drawbacks of conventional brushes by forming the base and tip of the brush wider.

[0005]

In order to solve the above-mentioned problems, the means adopted by the present invention is that the width of the root part (3) of the brush part (1) is 3 to 10 mm, preferably 4 to 6 mm. Is characterized by.

Further, the width of the base portion (3) of the brush portion (1) is 3 to 10
mm, the width of the brush tip (4) is 3 to 12 mm, preferably the brush section
The width of the root portion (3) of (1) is 4 to 6 mm, and the width of the writing tip portion (4) is 4 to 8 mm.

Further, the width of the base portion (3) of the brush portion (1) is 4 to 6
mm, and the shape of the brush tip portion (4) is fan-shaped.

Further, the thickness perpendicular to the width direction of the brush portion is set to 0.
The feature is that it is 5 to 3 mm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. In the figure, (1) is the brush portion of the brush for applying nail enamel, the width of the base portion (3) of the brush fixed to the pattern (2) is 3 to 10 mm, and the width of the tip portion (4) is 3 mm. It is characterized in that it is ~ 12 mm. Preferably,
The width of the base portion (3) of the brush is 4 to 6 mm, and the width of the brush tip portion (4) is 4 to 8 mm. The thickness of the brush portion (the dimension in the direction orthogonal to the width direction) is preferably 0.5 to 3 mm. Further, the shape of the brush tip may be formed straight as shown in FIG. 1 as in the conventional case, but it is preferably fan-shaped to match the shape of the nail as shown in FIG.

According to the survey, the width of the nail of the little finger of a woman is about 5 to 8 mm on average, and therefore even the little finger has a width of 5 mm or more.
Further, when the brush contains nail enamel, the width of the base and the tip of the brush are usually almost the same. Therefore, in the case of a brush whose base and brush tip have the conventional dimensions, it was necessary to repeat application in order to apply the entire nail, especially the wide nail such as the thumb.

According to the brush of the present invention, the width of the root portion (3) of the brush portion (1) is as wide as 3 to 10 mm, and the width of the brush tip portion (4) also depends on the width of the root portion (3). Since it is formed wide, a sufficient width is secured even if the brush contains nail enamel. When applying nail enamel to the nails,
Although (1) is pressed against the nail, the pressing force also varies from person to person, and the person who applies the nail enamel thinly presses the brush part strongly, so the spread of the brush tip increases,
People who apply it heavily do not press the brush part so the brush tip does not spread much. The brush of the present invention accurately responds to individual differences in such nail enamel application,
Even when the application is performed so that the tip of the writing brush does not spread so much, it has a sufficient writing width, and it is possible to reduce the number of times of applying the nail enamel and prevent uneven application.

Twelve persons were selected for the brush of the present invention in which the width of the base portion (3) of the brush portion (1) was 5 mm, and the tip of the brush was formed in a fan shape, and the conventional flat brush in which the width of the base portion was 2.7 mm. As a result of the usage test for the test subject, all 12 persons answered that the brush of the present invention was easier to apply than the conventional brush.
Further, the brush of the present invention is evaluated such that it is easy to perform fine work even if it is large, can be applied uniformly and evenly, can be applied quickly, does not stick out with rounded corners, contains a lot of liquid and is easy to apply. It was

[0012]

According to the present invention, since the width of the brush portion of the brush is sufficiently larger than the width of the nail, it is not necessary to apply the brush repeatedly, and uneven coating can be prevented.
