Description

Makeup brush

The present invention relates to a cosmetic brush for applying cosmetics to the skin such as the face.

In recent years, there has been an interest in makeup that professional makeup artists perform, and there is a growing need to easily obtain a makeup finish equivalent to that performed by makeup artists. Therefore, it is not uncommon for ordinary people to purchase makeup brushes used by makeup artists. However, because there are strong know-how elements regarding makeup, the current situation is that even if the same makeup brush is used, it cannot be performed as well as a professional makeup artist. For this reason, various cosmetic brushes have been proposed in order to approach the makeup method performed by makeup artists as much as possible, and the present applicant has already proposed a cosmetic brush as disclosed in Patent Document 1 below. The cosmetic brush is formed such that the front end surface of the brush part is formed in a concave shape, so that the cosmetic can be transferred substantially uniformly to the front end surface and the cosmetic can be applied to the skin substantially uniformly, such as wrinkles and pores. It is possible to reduce the emphasis on the minute unevenness of the skin. Such a cosmetic brush is excellent for approaching the professional makeup artist's area, but there is a demand for a brush that reaches the professional area even more.

On the other hand, one of professional methods is to give a three-dimensional effect. That is, the uneven shape derived from the face skeleton shape, for example, the cheekbone that is the central part of the face is generally a convex portion that protrudes compared to the surrounding, but corresponds to such an uneven shape If the foundation is evenly applied to the entire face without the three-dimensional effect, it is often finished in a flat expression as if it were “Noh mask”. Therefore, it is ideal to apply a thick coating around the cheekbone, which is the center of the face, and gradually apply it to the surrounding facial contours. It is not always easy for a general person who does not make makeup that produces a three-dimensional effect in accordance with the unevenness of the face portion.

JP 2013-85817 A

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a cosmetic brush that can easily make a three-dimensional makeup.

The present invention has been made to solve the above problems, and the cosmetic brush according to the present invention is a cosmetic brush for applying a powder cosmetic, and on the tip surface of the brush portion, A center application surface portion having a high hair density and a peripheral application surface portion having a hair density lower than that of the center application surface portion provided around the center application surface portion are provided. In addition, the density of the hair depends on the number per unit area.

In the makeup brush having such a configuration, the tip end surface of the brush portion is not a uniform hair density configuration, and a central application surface portion, which is a dense region with high hair density, is formed in the center portion, and the hair is formed on the outer side thereof. A peripheral coating surface portion which is a sparse region having a low density is formed. For example, a case where makeup is applied by applying a foundation as a powder cosmetic on the face will be described. When the foundation is applied to the tip surface of the brush part, a large amount is applied to the center application surface part where the hair density is high, and the hair density is low. A small amount is applied to the peripheral coating surface. And if you have a makeup brush with a lot of foundation attached to the center application surface like this and put the tip of the brush part on your face and make up, you can darken the area where the center application surface hits, The foundation can be spread thinly by the peripheral coating surface portion at the location. Therefore, first apply the central application surface part to the cheekbone, which is the center part of the face, and apply it while sliding it toward the peripheral part of the face, or direct it toward the peripheral part of the face while drawing a small circle. When applied, the foundation can be firmly attached to the cheekbone, which is the central part of the face, and it can be applied thinly while blurring toward the peripheral part of the face. Also, if you apply the center application surface part to the cheekbone, which is the center of the face, and apply it while drawing a circle from a small circle to gradually become a large circle, it will firmly adhere to the cheekbone The foundation can be applied deeply, and it can be applied while faintly blurring from the cheekbone to the outside.

In particular, it is preferable that the brush part includes an outer brush part made of a hair mixture in which a plurality of hairs having different lengths are mixed, and the peripheral edge application surface part is configured from the tip surface of the outer brush part. According to this configuration, since the peripheral coating surface portion is formed from the longest hair tip, the hair density on the tip surface of the outer brush portion is reduced. That is, it is possible to easily form the peripheral coating surface portion that is a sparse region due to the difference in hair length. Although it is possible to reduce the density of the hair on the tip surface by reducing the number of hairs that make up the outer brush part, the manufacturing becomes complicated and the use of thick hair makes it stronger Too. On the other hand, when the outer brush portion is composed of a mixed hair mixed with a plurality of hairs having different lengths, the number of hairs constituting the outer brush portion is reduced without reducing the number of the tips. And the density of the hair on the tip surface can be easily reduced. Further, since the tip of the longest hair preferentially hits the skin, a soft touch can be easily obtained at the peripheral coating surface. In addition, the relatively short hairs support the longer hairs and suppress extreme bending of the long hairs, forming a moderately stiff outer brush part while ensuring a soft touch. can do.

Furthermore, it is preferable that the outer brush part is composed of a hair mixture in which two kinds of hairs having different lengths are mixed. The outer brush part can be made up of three or more types of mixed hair bodies, but the construction of the outer brush part is facilitated by the construction of two kinds of mixed hair bodies of long hair and short hair. It is also easy to control various balances between soft touch and moderate stiffness.

In that case, it is particularly preferable that the mixing ratio of long hairs in the outer brush portion is 50% or less, and that the outer brush portion can have an appropriate stiffness while ensuring a soft touch. In particular, it is more preferable that the mixing ratio of long hairs in the outer brush portion is 5 to 15%.

Further, it is preferable that the difference in length between the long hair and the short hair in the outer brush portion is 2 mm to 10 mm. If the difference between the length of the long hair and the short hair is less than 2 mm, it is difficult to obtain the effect of low density in the peripheral coating surface portion, and the amount of powder cosmetics such as foundation adhering to the central coating surface portion and the peripheral coating surface portion It is difficult to make a difference between the amount of powder cosmetics such as foundation adhering to the surface. On the contrary, if the difference in length exceeds 10 mm, the effect of supporting the short hair by the short hair is weakened, and the stiffness at the tip of the long hair becomes too weak. The diffusion effect of blurring while spreading the peripheral coating surface portion thins.

Further, the brush part has an inner and outer two-layer structure composed of the outer brush part and an inner brush part in which the lengths of the hairs are aligned, and the central application surface part is configured from the tip surface of the inner brush part. preferable. By aligning the lengths of the hairs of the inner brush part, it is possible to easily apply a lot of cosmetics to the central application surface part in combination with the high density of the hair in the central application surface part.

Further, it is preferable that the density of the hair on the peripheral application surface portion is 0.5 or less with respect to the density of the hair on the central application surface portion. In other words, when the density of the hair on the central application surface portion is 1, and the density of the hair on the peripheral application surface portion is 0.5 or less, natural makeup with a three-dimensional effect can be obtained due to the density of the central application surface portion and the peripheral application surface portion. This can be done even more easily. In addition, it is still more preferable that the density of the hair of a peripheral coating surface part is 0.1 or less.

As described above, according to the present invention, since the central application surface portion that is a dense region and the peripheral application surface portion that is a sparse region are provided on the tip surface of the brush portion, a convex portion such as a central portion is formed in accordance with the uneven shape of the face. Since it is dark on the part and can be applied thinly on the concave part such as the peripheral part, makeup with a three-dimensional effect can be easily performed.

Hereinafter, a cosmetic brush according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the cosmetic brush of the present embodiment is for applying a powder cosmetic to the face. Examples of the powder cosmetic include foundations such as pressed powder and loose powder, and teak. . Such a makeup brush includes a handle portion 1 and a brush portion 2 attached to a tip portion of the handle portion 1.

The length and shape of the handle portion 1 are arbitrary. For example, the handle portion 1 has a truncated cone shape that gradually increases in diameter from the base end portion on the opposite side to the brush portion 2 to the tip end portion on the brush portion 2 side. It is about 5 cm to 15 cm. The handle 1 is composed of, for example, a first handle 11 on the proximal end side and a second handle 12 on the distal end side. The first handle 11 is, for example, a cylindrical shape, and the material thereof is, for example, a synthetic resin. The second handle 12 is attached to the tip of the first handle 11 and has, for example, a cylindrical shape, and the material thereof is metal or synthetic resin. As described above, in the present embodiment, the handle portion 1 is composed of two members, but may be composed of one member, and in any case, at least the tip portion is cylindrical and the brush portion is inside thereof. It is preferable that the structure is such that 2 can be mounted.

The brush part 2 is attached and fixed to the inside of the tip part of the handle part 1 (that is, the tip opening part of the second handle part 12) with an adhesive or the like. In the present embodiment, the brush portion 2 has a circular cross section, that is, a columnar shape or a truncated cone shape that gradually increases in diameter from the base end portion to the tip end portion. The proximal end portion of the brush portion 2 is fixed to the inner peripheral surface of the distal end portion of the handle portion 1, and therefore the brush portion 2 is in a state where the proximal end fixed distal end is free. The length of the hair is, for example, 40 mm to 80 mm, and the length exposed from the handle 1 is, for example, 20 mm to 70 mm. Moreover, the front end surface 2a of the brush part 2 is an application surface for apply | coating powder cosmetics, and the front end surface 2a of the brush part 2 is a flat surface in this embodiment. The front end surface 2a of the brush portion 2 is divided into two regions, an inner region and an outer region, and forms an inner region, and is provided in a ring shape around the center application surface portion 20 having high hair density and outside the center application surface portion 20. The outer peripheral region, and the peripheral application surface portion 21 having a hair density lower than that of the central application surface portion 20. As shown in FIG. 2A, the diameter A of the central application surface portion 20 is, for example, 15 mm to 30 mm, and the width B (diameter dimension) of the peripheral application surface portion 21 is, for example, 5 mm to 10 mm. It is preferable that at least the diameter A of the central application surface portion 20 is larger than the width B of the peripheral application surface portion 21.

Moreover, it is preferable that the density of the hair of the peripheral application surface part 21 is 0.5 or less with respect to the density of the hair of the center application surface part 20. That is, when the density of the hair of the central application surface portion 20 is 1, the density of the hair of the peripheral application surface portion 21 is preferably 0.5 or less, and particularly the peripheral application surface portion with respect to the density of the hair of the central application surface portion 20. The hair density of 21 is more preferably 0.1 or less. As an example of the hair density, for example, in the central coating surface portion 20 is 700 or / 28mm ^2, in the peripheral coating surface portion 21 is 50 lines / 28mm ^2.

The specific structure of the brush part 2 will be described. As shown in FIG. 2 (b), the brush part 2 has a two-layer structure composed of two layers, an inner and an outer layer. That is, the brush part 2 is comprised from the inner side brush part 22 which comprises an inner layer, and the outer side brush part 23 which comprises an outer layer. The inner brush portion 22 has a columnar shape or a truncated cone shape and constitutes a central portion of the brush portion 2, and the lengths of the bristles are aligned. The tip surface of the inner brush portion 22 is circular as shown in FIG. 2A, and constitutes a central application surface portion 20 that is the central portion of the tip surface 2 a of the brush portion 2. The inner brush portion 22 is composed of a single hair, and specifically, animal hair is used. Examples of animal hair include horse hair, weasel hair, squirrel hair, goat hair, and pig hair.

Further, the outer brush portion 23 is formed in a cylindrical shape so as to surround the outer side of the inner brush portion 22. The outer brush portion 23 and the inner brush portion 22 are substantially concentric, and the peripheral coating surface portion 21 is configured from the annular tip surface of the outer brush portion 23. The outer brush portion 23 is composed of a hair mixture obtained by mixing a plurality of hairs having different lengths. Specifically, as shown in FIG. 3, the outer brush portion 23 is composed of a mixed hair body in which two kinds of hairs, long hairs 30 and short hairs 31 are mixed. The length difference D between the long hairs 30 and the short hairs 31 is preferably 2 mm to 10 mm. Due to this difference in length D, a step is generated at the tip of the outer brush portion 23, and the peripheral application surface portion 21 is constituted only by the long hairs 30, and the density of the hair on the peripheral application surface portion 21 is lowered. If the difference D between the lengths of the long hairs 30 and the short hairs 31 is less than 2 mm, it is difficult to obtain the effect of low density in the peripheral coating surface portion 21, and conversely if the difference in length D exceeds 10 mm, the short hairs The effect of 31 supporting the long hair 30 is weakened, and the stiffness at the end of the long hair 30 becomes too weak. Therefore, the length difference D between the long hairs 30 and the short hairs 31 is preferably 2 mm to 10 mm.

Further, the mixing ratio of the long hairs 30 in the mixed hair body is preferably 50% or less. In other words, it is preferable that the ratio of at least the long hairs 30 is equal to or less than that of the short hairs 31, and an appropriate stiffness can be provided while ensuring a soft touch in the outer brush portion 23. In particular, the mixing ratio of the long hairs 30 is more preferably 5 to 15%.

In the present embodiment, the long hairs 30 are synthetic fibers, and the short hairs 31 are animal hairs. Synthetic fibers include polyamide fibers, polyolefin fibers, polyacrylonitrile fibers, polyester fibers, etc., and in particular, having moderate rigidity and durability, and excellent post-processing properties such as twisting and tapering, Polyester fibers are preferred. Polyester fibers include polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), etc., and in particular, polybutylene terephthalate because it has appropriate flexibility and elasticity. (PBT) and polytrimethylene terephthalate (PTT) are preferable, and polytrimethylene terephthalate (PTT) is particularly preferable because of its excellent flexibility and deformation recovery characteristics depending on its molecular structure. The thickness of a single hair made of synthetic fibers is about 0.02 mm to 0.2 mm, and about 0.05 mm to 0.15 mm is particularly preferable from the viewpoints of processability, touchability, and collection of cosmetics. .

Furthermore, when synthetic fibers are used, it is preferable to form a region having a predetermined length at the tip as a tapered shape as shown in FIG. In order to taper the tip of the synthetic fiber, for example, a method of immersing the tip of the synthetic fiber upside down in a processing solution for dissolving or decomposing the synthetic fiber from above is preferable. An example of the treatment liquid is an aqueous sodium hydroxide solution. The length L of the tapered tapered portion 32 is, for example, 20 mm to 30 mm, and is preferably longer than at least the length difference D between the long hair 30 and the short hair 31.

Further, animal hair similar to that described above can be used, and in this embodiment, the inner brush portion 22 and the short hair 31 of the outer brush portion 23 are composed of the same animal hair.

The cosmetic brush having the above configuration can be manufactured, for example, as follows. First, as shown in FIG. 4 (a), bristles are put into a cylindrical shape with a bottom opening (not shown) having an opening on the upper surface, gathered into a cylindrical shape, and the base end portion is fixed with a thread or the like, and the inner brush portion 22 is formed. On the other hand, as shown in FIG.4 (b), the long hair 30 and the short hair 31 are mixed by a predetermined | prescribed mixing ratio, and are arranged in the planar form, aligning the base end part of hair. Then, the inner brush portion 22 is placed on a flat hair mixture, and the inner brush portion 22 is rolled around the center line while rolling so that the inner hair portion 22 is rotated around the center line. After forming the outer brush portion 23 in the bag and arranging the whole in the same manner as described above, the base end portion of the formed brush portion 2 is hardened with an adhesive or the like, and the base end portion of the brush portion 2 is patterned. Attach to part 1.

In the cosmetic brush manufactured in this way, the tip surface 2a of the brush portion 2 is not configured to have a uniform hair density as in the prior art, but a dense hair with a high hair density in the central portion. A central application surface portion 20 that is a region is formed, and a peripheral application surface portion 21 that is a sparse region having a low hair density is formed on the outer side thereof, so that makeup with a three-dimensional effect can be easily performed. For example, when the foundation contained in the cosmetic container is applied to the distal end surface 2 a of the brush portion 2, the transition is made more to the center application surface portion 20 and less to the peripheral application surface portion 21. And if you put on the face of the tip surface 2a of the brush part 2 with a makeup brush with a lot of foundation attached to the center application surface part 20 and apply it to your face, you can darken the part where the center application surface part 20 hits, The foundation can be thinly spread by the peripheral application surface portion 21 at the peripheral portion.

For example, as shown by the double-lined arrow E in FIG. 5, first, the central application surface portion 20 is applied to the cheekbone, which is the central portion of the face, the middle of the eyebrows, and the upper portion of the face, and then toward the peripheral portion of the face When applied while sliding, the foundation can be firmly attached to the central part of the face, which is a convex part protruding forward, and toward the peripheral part of the face, which is a concave part recessed relatively backward After that, you can gradually spread the foundation and apply it thinly. In this case, the makeup brush may be gradually moved to the peripheral portion of the face while drawing a small circle.

Further, as indicated by a single-line arrow F in FIG. 5, the center application surface portion 20 is applied to the cheekbone which is the center portion of the face, and a small circle is drawn at first, and then the circle gradually. You can apply it by rotating the makeup brush while turning it up, and you can apply a strong foundation firmly on the cheekbones, and apply it while faintly blurring from the cheekbones outward. Can continue.

Further, since the outer brush portion 23 is composed of a mixture of long hairs 30 and short hairs 31, the peripheral coating surface portion 21, which is a sparse region, can be easily formed by the difference in hair length D. And since the front-end | tip of the long hair 30 touches skin preferentially, the soft touch can also be obtained in the peripheral application surface part 21, and since the relatively short hair 31 supports the long hair 30, the long hair 30 Can be suppressed. Thus, by comprising the outer brush part 23 from the mixed hair body of the long hair 30 and the short hair 31, the outer brush part 23 with moderate stiffness can be easily formed while ensuring a soft touch. .

In the present embodiment, the same animal hair is used for the short hairs 31 of the inner brush portion 22 and the outer brush portion 23, but different animal hairs may be used, or one may be animal hair and the other may be synthetic fiber. Further, in the outer brush portion 23, the long hairs 30 are synthetic fibers and the short hairs 31 are animal hairs, but this may be reversed, and both the long hairs 30 and the short hairs 31 are animal hairs or synthetic fibers. Also good. Moreover, although the inner brush part 22 was comprised from the single hair, it is good also as this hair mixture. Furthermore, all the hair which comprises the brush part 2 may be animal hair, or conversely may be all synthetic fiber. For example, the short hair 31 of the inner brush portion 22 and the outer brush portion 23 may be PBT, the long hair 30 of the outer brush portion 23 may be PTT, or all the hairs of the brush portion 2 may be PBT. Furthermore, although the outer brush portion 23 is made of a mixture of two types of hair, it may be a mixture of three or more types of hair. Further, the inner brush portion 22 may also be composed of a mixture of long hairs 30 and short hairs 31, and in that case, the composition ratio of the long hairs 30 in the inner brush portion 22 is set higher than that of the outer brush portion 23. By making it high, the density of the hair of the center application surface part 20 is made higher than the density of the hair of the peripheral application surface part 21. When the inner brush portion 22 and the inner brush portion 22 are mixed with a plurality of hairs having different lengths, the hair length difference D is relatively small for the inner brush portion 22 and the outer brush portion 22 The brush portion 23 is preferably relatively large.

Moreover, although the outer brush part 23 was comprised from the mixed-hair body of several hair from which length differs, the density of the hair of the peripheral coating surface part 21 was made low, but it does not utilize the difference D of hair length, but outside. The density of the hair on the peripheral application surface portion 21 may be lowered by making the number of hairs constituting the brush portion 23 smaller than that of the inner brush portion 22. That is, the inner brush part 22 uses thin hairs to increase the number per unit area, and the outer brush part 23 uses thick hairs to reduce the number per unit area. You may make the density of the hair in the front end surface 2a inner dense and outer sparse. Of course, you may make it dense by using the hair in which thickness differs, utilizing the difference D in hair length.

Furthermore, the tip surface 2a of the brush portion 2 may be a convex surface with a raised central portion as shown in FIG. 6 instead of a flat surface as shown in FIG. In addition, you may make the whole front end surface 2a of the brush part 2 convex shape, and you may make only the center application | coating surface part 20 convex shape. In this way, if the entire front end surface 2a of the brush portion 2 is formed in a convex shape, or only the center application surface portion 20 is formed in a convex shape, it becomes easy to attach a large amount of cosmetic material to the center application surface portion 20.

Still further, the present invention is not limited to the case where the central application surface portion 20 is substantially flush with the peripheral application surface portion 21, and the central application surface portion 20 may protrude from the peripheral application surface portion 21. For example, as shown in FIG. 7, when the peripheral application surface portion 21 of the brush portion 2 is a flat surface, the center application surface portion 20 may be protruded forward by a predetermined length with respect to the peripheral application surface portion 21. As described above, when the center application surface portion 20 protrudes to the front side from the peripheral application surface portion 21, the center application surface portion 20 may be a flat surface with a substantially constant protrusion amount as shown in FIG. 7 (b) may be a convex surface in which the protruding amount of the central portion is larger than that of the peripheral portion. The same applies to the case where the peripheral edge application surface portion 21 of the brush portion 2 is convex as shown in FIG. 8A and 8B exemplify the case where the central application surface portion 20 is a convex surface. As shown in FIG. 8A, the central application surface portion 20 may protrude so that the protrusion amount with respect to the peripheral application surface portion 21 is substantially constant, or as shown in FIG. The center application surface part 20 may protrude so as to be larger than the above. In any case, when the center application surface part 20 is configured to protrude from the peripheral application surface part 21, cosmetics are more easily attached to the center application surface part 20, and the makeup is applied by the center application surface part 20 to which more cosmetics are attached. There is an advantage that the coating can be easily and densely applied to a specific location.

Moreover, although the case where the front end surface 2a of the brush portion 2 is circular has been described, it may be elliptical or elongated oval, and the shape or cross-sectional shape of the front end surface 2a of the brush portion 2 may be used. Various changes can be made.
