Description

  The present invention relates to a makeup brush and a makeup method using the makeup brush. More particularly, makeup and powdery and liquid cosmetics for makeup can be applied cleanly as a makeup artist finishes the makeup. The present invention relates to a brush and a makeup method performed using the makeup brush.

Conventionally, makeup brushes for applying cosmetics such as face brushes, cheek brushes, eye shadow brushes, eyebrow brushes, etc. have been widely used, but the overall shape of the makeup brush is the tip of the tip of the brush tip. A shape with a round shape with a bulge or a brush shape for paint has been proposed.
As a makeup brush that has a slightly larger hair tip, especially a face brush or cheek brush, and applies foundation to the entire face, the hair tip surface (meaning the surface touching the skin at the tip of the hair tip) However, a round brush (kamaboko-shaped) that swelled gently near the center was common.

In a cosmetic brush suitable for applying such a foundation, when applying cosmetics to the face, the cosmetics are adhered from the container to the hair tips of the cosmetic brush, and the adhered cosmetics are applied to the face, around the eyes, and the nose. , Applied to the nose, cheeks, chin, etc. while touching.
The following publications exist as typical cosmetic brushes.

Japanese Utility Model Publication No. 5-44428 Japanese Patent Laid-Open No. 10-165224

  As described above, when applying cosmetics represented by foundations, it is relatively easy to apply cosmetics with a sponge puff, even for amateurs, but when using a makeup brush However, there is a problem that a technique is required to apply the cosmetics uniformly and thinly, and it cannot be used well by ordinary people without the technique.

  In addition, the conventional makeup brush is formed such that the tip of the tip of the brush tip swells in the central part (kamaboko shape), and is formed so that the tip of the tip spreads toward the tip (the side shape of the tip of the tip is the tip) It is difficult to make the entire surface of the brush tip, i.e., the entire tip of the brush, touch the skin evenly, and how the force is applied to the tip. Since it was not uniform, it was difficult to uniformly apply the cosmetic, and there was a problem that a fit could not be obtained during use.

  Therefore, the present invention provides a cosmetic brush of a new form having a hair tip surface portion of a hair tip of a brush having a flat shape, and a side shape of the hair tip being a substantially straight shape toward the tip. The present invention is intended to solve all the above-mentioned problems by providing a makeup brush having a good makeup and a makeup method using the same, which has both ease of application of a puff and ease of application of a makeup brush.

  The cosmetic brush according to claim 1 of the present invention does not generate a bending point when applying a load for pushing and bending the hair tip by 2 mm to 4 mm, and applies a load for pushing and bending the hair tip by 2 mm to 4 mm. The load increase when the load is almost constant, or the load increase slope is 0.62 N / mm or less, and the condition of the hair flexibility is that the tip length is 25 mm or less. It has the condition about the length of the hair tip, and has the condition about the brush caliber that the caliber of the brush is 16 mm to 44 mm. It is a makeup brush with the condition about the spread angle of the bunch of hair that is within 20 degrees to the outside, and the tip surface portion of the tip of the brush is formed to have a flat shape It is a makeup brush characterized by.

  Further, according to a second aspect of the present invention, the cosmetic brush according to the first aspect is characterized in that the side surface shape of the tip surface portion of the tip of the brush is inclined.

  Further, the third aspect of the present invention uses the makeup brush according to the first or second aspect of the present invention so that the hair tip surface portion of the brush tip is applied to the makeup target portion multiple times or to be slid while being struck. It is a makeup method characterized by applying a material.

The cosmetic brush according to claim 1 of the present invention has an effect that good results can be obtained in use feeling such as fit and softness per skin, uniformity of finish, and makeup finish of the finished makeup.
According to the questionnaire results (31 panels) regarding makeup holding when using the makeup brushes according to the present invention, 73% are certified as having good makeup, and 10% are certified as somewhat acceptable. The result of certification that it is neither is 7%, and the result of certification that it is not is 10%.

  Moreover, since the makeup | decoration brush of Claim 2 is formed so that the side surface shape of the hair-tip surface part of a brush tip may exhibit inclined shape, even if it holds and uses the pattern equivalent to a holder part diagonally, Since the flat hair end surface portion can be easily touched to the skin in a vertical manner, there is an effect that the feeling of fit and softness per skin and the uniformity of the finish are further improved.

  According to a third aspect of the present invention, the makeup brush according to the first or second aspect is used, and the tip of the hair tip of the brush is struck on the makeup target portion a plurality of times, or slid while tapping. Since the cosmetics are applied, even the general public can apply the cosmetics cleanly as the makeup artist finishes, and the finished makeup has a good effect.

Hereinafter, embodiments of the makeup brush and the makeup method of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.
A makeup brush 1 according to the present invention shown in FIGS. 1 to 5 is configured by attaching a hair tip 4 to a tip of a handle 2 via a base 3.
The hairs that make up the hair tips 4 are horse hair, weasel, gray squirrel, pine squirrel, Canadian squirrel, goat, fox, deer, cow, sheep, fox, monkey, cat, fox, pig, wolf, flying squirrel and other beasts. Using hair, using synthetic fiber hair such as PBT (polybutylene terephthalate), nylon, PET, etc., or mixing them at an appropriate mixing ratio, gives the entire brush stiffness and elasticity. Durability and ease of use, and the contact feeling (per skin) of the hair tip 5 to the skin surface are improved.

Further, it was found that when the value obtained by multiplying the Young's modulus and the cross-sectional area of the hair is larger than 6 kN, there is some discomfort during use, and it is preferable that the value is 6 kN or less.
Moreover, about the hair tip, it turned out that it is more preferable when the taper process for improving per skin is performed.

First, the makeup brush 1 of the present invention is formed by binding the above-described brush hairs and firmly attaching them to the handle 2 while squeezing them with a base 3 to form a hair tip 4, and a hair tip surface portion 5 of the hair tip 4 is formed flat. Has been.
In addition, the code | symbol L1 in a figure has shown the length of the hair tip 4, and L2 has shown the aperture of the brush.

The cosmetic brush of the present invention, which is represented by the following formula A, has been found to give good results in the feeling of use and finish, and to improve the makeup of the finished makeup.
Formula A → (Condition of hair flexibility) + (Condition of length of hair tip) + (Condition of caliber of brush) + (Condition of angle of spread of hair bundle of brush)

(Conditions for hair flexibility)
When the bristles were bent, when the bristles were pushed and bent by 2 mm to 4 mm, it was considered that the situation when the brush was actually used was reproduced, so the physical properties were measured. Regarding the magnitude of the load (N) when the bristles were pushed and bent by 2 mm to 4 mm, the brushes of any shape measured were within 40N.
On the other hand, with respect to a graph obtained by plotting the load against the distance when the hair end is pushed and bent, the change in load when the hair tip is pushed and bent by 2 mm to 4 mm has the following condition B. It was found that good results were shown in the feeling of use such as softness per skin and uniformity in finish. For this measurement, an autograph manufactured by Shimadzu Corporation was used.
B-1 (The increase in load when 2mm to 4mm is pushed and bent is smooth, and there is no bending point)
B-2 (The increase in load when pushing and bending 2 mm to 4 mm is almost constant, or the gradient of the increase is a gradual increase of 0.62 N / mm or less.)
In addition, about the brush whose hair-tip surface part 5 is diagonal, it applied and measured so that it might become parallel to the surface of the hair-tip surface part 5. FIG.

(Conditions for length of hair ends)
When the bristles are shortened, the feel becomes somewhat hard and the feeling of use decreases, but there is no problem.If the bristles are too long, the bristles of the brush will be refracted during use, making it difficult to apply a uniform load. However, it was found that there was a problem in the uniformity of the finish.
As a result, it was found that the length L1 of the hair tip is preferably 25 mm or less.

(Brush caliber condition)
If the caliber L2 of the brush is too small, fine details can be finished beautifully, but it takes a long time to apply the foundation to the entire face, and if the caliber L2 is too large, It took a long time to apply the foundation to the whole and it was convenient, but there was a problem that it was difficult to finish fine details beautifully. It was found that an appropriate aperture L2 satisfies the following conditions. The diameter L2 of the brush is the dimension of the base 3 portion where the bristles 4 of the brush 1 are joined. If the cross-sectional shape is circular, the diameter is the same, and if the cross-sectional shape is elliptical, the short diameter Means that.
As a result, it was found that the diameter L2 of the brush is preferably 16 mm to 44 mm.

(Brush hair bundle spread angle requirement)
It has been found that a shape with a widened hair tip that is commonly seen generally is not suitable as a brush having a shape for applying a foundation in the application method of the present invention.
The cosmetic brush of the present invention uses a material of almost uniform length, and the spread of the hair tip with respect to the portion of the handle 2 is slightly outward from the case where the handle 2 and the hair are linear. Although there is no problem in the feeling of use and the finish, the spreading angle α of the hair bundle of the brush formed by intersecting the hair stretching direction axis 6 and the outermost spreading direction axis 7 of the hair bundle is 20 on the outside. In the case of spreading beyond the degree, the hair tips 4 further spread at the time of use, and there is a problem that the fit feeling is lowered or it is difficult to finish uniformly. Therefore, the spread angle α of the bristle bundle of the brush needs to be within 20 degrees to the outside with respect to the bristle stretching direction axis 6.

In addition, when the hair tip 4 does not spread outward and is substantially on the same line as the base 3 portion of the handle 2, a good result is shown, and the hair tip 4 bites inward than on the same line as the handle 2 Regarding the case (when facing the inner side of the hair stretching direction axis 6), good results were similarly obtained. Due to the structure of the makeup brush 1, it was difficult to produce a brush that digs into the inner side of the hair stretching direction axis 6 by 20 degrees or more. When it entered inside, there was no problem at any angle, and good results were shown.
Furthermore, it was found that when the hair tip surface portion 5 of the hair tip 4 of the makeup brush 1 has a flat shape, the hair tip surface portion touches the skin evenly with an average pressure, and good results are shown. Further, it is found that when the side surface shape of the hair tip surface portion 5 of the brush tip 4 is inclined (see FIGS. 3 and 4), the feeling of use and the finish are further improved and the usability is improved. It was.

Below, the total result of the answer questionnaire showing the result of the effect for each item of the example and the comparative example is shown. For each item, the most numerous results are indicated by symbols ◎, ○, △, and ×, ◎ is very good, ○ is slightly better, △ is slightly inferior, × is very inferior It shows the content.
The number of panels is 31. “Beautiful finish” means clearness, glossy finish (non-powdered finish), three-dimensionality, natural finish, makeup, uneven pores and acne scars This is a result of comprehensive determination of power, covering power of skin color unevenness such as freckles and freckles, uniformity of the entire face, etc., and uniformity of powder that can be confirmed when magnified observation is performed with a microscope.
