  However, the hair dyeing comb described in Patent Document 1 has a thick hair portion when the hair dye remains on the thick hair portion at the center of the brush portion after the hair dye is applied to the hair, and the hair coloring starts. There is a problem that the hair dye put on can not be used up. In addition, since the thick and fine hair parts of the brush part are both made by resin molding, the flexibility of the brush part is insufficient, and the hair dye splashes when applying the hair dye to the hair at the brush part The hair dyeing work is difficult.

  On the other hand, the hair dyeing comb described in Patent Document 2 is composed only of brush hairs in which the brush part is planted, and therefore, after the hair dye is applied to the hair, the hair dye is applied to the central part of the hair dyeing comb. However, if the root of the part to be applied is not exposed, the hair dye is applied to the base of the hair. Hateful.

  Since the comb described in Patent Document 3 has a comb portion made of resin-molded comb teeth and a brush portion made of flocked brush hair arranged side by side, the hair dye can be prevented from splashing during hair dyeing, Since the part on which the hair dye is placed is a narrow region called the step portion between the comb part and the brush part, it is difficult to place the hair dye.

  Accordingly, the present invention provides a hair dye applicator having a brush portion in which a comb tooth portion made of comb teeth and a hair transplant portion made of planted brush hair are arranged side by side. An object is to make it possible to easily put a hair dye and to prevent the hair dye from remaining unnecessarily in the brush portion after the hair dye has been applied.

  The present inventor provides a hair dyeing applicator having a comb tooth portion composed of comb teeth and a flocked portion composed of brush hairs, provided with flocked portions on both sides of the comb tooth portion along the comb tooth row, and comb teeth If the height of the brush hair of the flocked part is made higher than the comb tooth of the part, and the comb tooth part becomes a concave part sandwiched by the flocked part, an appropriate amount of hair dye can be easily placed in the concave part, At this time, if the base surface of the applicator body on which the comb teeth and the brush hairs stand is protruded by the comb tooth portion with respect to the flocked portion, the hair dye can be prevented from remaining unnecessarily in the comb tooth portion after the hair dyeing. I found.

That is, the present invention is a hair dyeing applicator having a comb tooth portion in which comb teeth are arranged and a hair transplant portion in which brush hairs are planted,
The flocked portion is provided on both sides of the comb tooth portion along the comb tooth row,
The height of the brush hair is higher than the height of the comb teeth,
Provided is a hair dyeing applicator in which a base surface of an applicator main body on which comb teeth and brush hairs stand up projects from the flocked portion with a comb tooth portion.

  According to the hair dye applicator of the present invention, since the comb tooth portion and the flocked portion are arranged side by side in the brush portion, hair can be easily dyed to the base of the hair, It is not necessary to keep the root exposed. In addition, the hair dye can be prevented from splashing during hair dyeing.

  Further, in the brush portion of the hair dye applicator of the present invention, the comb tooth portion becomes a concave portion sandwiched between the flocked portions, so that an appropriate amount of a hair dye can be easily placed in the concave portion, and the comb teeth and Since the base surface of the applicator body where the brush hair stands up is projected from the comb tooth portion with respect to the flocked portion, the hair dye easily flows from the comb tooth portion to the flocked portion at the time of hair dyeing. It is possible to prevent the agent from remaining unnecessarily in the comb teeth portion.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 2 is a side view of the hair dye applicator 1A according to one aspect of the present invention, and FIG. 1 is a perspective view (a), a top view (b), and a cross-sectional view (c) of the brush portion 10.

  This hair dyeing applicator 1A is provided with a comb portion 3 integrally molded with the handle 2 at one end portion of the plate-like handle 2, a brush portion 10 provided at the back of the comb portion 3, and at the other end of the handle 2. A slice portion 4 formed by resin molding integrally with the handle 2 is provided.

  The brush portion 10 includes a comb tooth portion 11 in which resin-molded comb teeth 12 are arranged, and a flocked portion 13 provided so as to surround the entire circumference of the comb tooth portion 11.

  The comb teeth 12 of the comb teeth portion 11 are preferably columnar with a diameter of 1.2 to 1.8 mm and a height of 3 to 8 mm. The arrangement of the comb teeth 12 may be arranged in two rows as illustrated, or may be arranged in one row or three or more rows, depending on the diameter.

  In the flocked portion 13, bristles 15 in which the bristles 14 are flocked in a bundle are arranged in a single line on both sides of the comb tooth portion 11 along the comb tooth row, and are also arranged on both ends of the comb tooth row. It is provided and surrounds the comb tooth portion 11. In particular, at the distal end portion of the brush portion 10, a plurality of bristles 15 are arranged, and the region of the flocked portion 13 expands in the direction of the distal end portion of the brush portion 10. The arrangement of the bristle 15 may be single over the entire circumference of the comb tooth portion 11 as shown in FIG. 6, but the region of the flocked portion 13 is enlarged at the tip of the brush portion 10 as shown in FIG. By doing so, it becomes possible to easily perform partial dyeing of the hairline and the root of the hair using the flocked portion 13a at the tip.

  The height of the tip of the brush hair 14 of the flocked portion 13 is higher than the height of the tip of the comb tooth 12. Therefore, the outer shape of the brush portion 10 has a shape in which the comb-tooth portion 11 at the center portion is recessed with respect to the surrounding flock portion 13. Therefore, when applying a hair dye to the hair using this hair dye applicator 1A, an appropriate amount of paste-like hair dye can be easily placed in the dent of the brush portion 10 and applied to the hair. It becomes possible to hold it stably until it is applied. In order to allow the hair dye to be easily placed in the recess of the brush portion 10, the flocked portion 13 may be provided at least on both sides of the comb tooth portion 11 along the comb tooth row. It may not be provided so as to surround the entire circumference of the tooth portion 11. The specific height H1 of the brush bristles 14 is preferably 8 to 12 mm, and the height difference H2 between the tips of the brush bristles 14 and the tips of the comb teeth 12 is preferably 3 to 5 mm.

  Further, the brush hair 14 is preferably made of polyamide or the like and having a diameter of 0.1 to 0.3 mm. As the color of the brush hair 14, the amount of the hair dye taken on the comb tooth portion 11 and the hair dyeing work can be performed by using a non-colored or lightly colored one in addition to the general opaque black colored one. It becomes easy to confirm the remaining amount of the brush and the tip position of the brush hair 14 at the time of partial dyeing.

  The width L1 in the longitudinal direction of the flocked portion 13 surrounding the comb tooth portion 11 is 35 to 50 mm from the viewpoint that an appropriate amount of paste-like hair dye can be placed between the flocked portions 13 facing each other with the comb tooth portion 11 interposed therebetween. Moreover, it is preferable that the space | interval L2 of the flocked part 13 which pinches | interposes the comb-tooth part 11 shall be 7-13 mm.

  Regarding the degree of bending of the flocked portion 13, as shown in FIG. 5, the brush hair 14 has a thickness of 1 mm at a height of 10 mm over the entire length in the longitudinal direction of the flocked portion 13 on one side of the comb tooth portion 11. The pressing plate 20 is applied so as to be in line contact, and as indicated by an arrow, the brush bristles 14 are pressed and elastically deformed in the direction from the flocked portion 13 to the comb tooth portion 11 in a direction perpendicular to the standing direction of the bristles 14. In this case, the pressing force required to set the displacement amount x of the bristles 14 at the pressing position to 2.5 to 5.5 mm is set to 0.7 to 1.3 N per 10 mm width of the flocked portion. It is preferable. The degree of bending of the flocked portion 13 is such that the flocked portion 13 composed of a plurality of bristle 15 is regarded as one elastic beam, and the degree of bending is limited to a specific range. When the hair dye is placed on the comb tooth portion 11 and applied to the hair, the hair dye can be reliably prevented from splashing, and the hair transplanting portion 13 pushes the hair dye toward the root of the hair while combing. It becomes easy to comb the hair with the tooth portion 11, and furthermore, it becomes easy to spread the hair dye over the entire hair with the flocking portion 13.

  About the bending degree of the flocked part 13, the relationship between the displacement amount x per 10 mm width of the flocked part 13 and the pressing force can be specifically measured according to JIS K7181-1994. That is, when the pressing force of the bristle is measured by using a compression tester at a pressing speed (moving speed) of 20 mm / min, the maximum value is obtained while pressing the pressing plate 20 against the bristle 14 and pressing 10 mm. . In addition, when the external shape of the flocked part 13 to which the pressing plate 20 is applied is a curved surface, the relationship between the displacement amount x and the pressing force is obtained by applying the pressing plate 20 along the curved surface.

  The degree of bending of the flocked portion 13 depends on the material of the bristles 14, the thickness of the bristles 14, the number of flocked brush hairs 14 per bristle, the diameter of the flocked holes of the bristles 15, the pitch of the flocked holes, and the like. Therefore, in this invention, these are set suitably so that the bending degree of the flocked part 13 may become the above-mentioned range. For example, polyamide is used for the material of the brush hair 14, the thickness of the brush hair 14 is 0.2 mm, the number of the brush hair 14 per bristle is 30, the diameter of the hair hole of the bristle 15 is 1.4 mm, A preferable degree of bending can be obtained when the pitch of the pores is 3 mm. On the other hand, for example, if the length, thickness, number of flocks, and flock hole pitch of the bristles are the same and a brush bristle material with a low modulus of elasticity is used, the flocked parts will be liable to be spread and the hair dye applied. It becomes difficult. On the other hand, if a brush material with a high elastic modulus is used, the flocked portion becomes hard and difficult to be formed, and problems such as scattering of the agent during application tend to occur. Similarly, when the structure for reducing the rigidity of the flocked portion, for example, reducing the thickness of the brush hair, reducing the number of flocked hair, increasing the pitch of the flocked hole, etc., the flocked portion is likely to bend, and the hair dye is used. It becomes difficult to spread. On the other hand, if the configuration to increase the rigidity of the flocked portion, for example, increase the thickness of the brush hair, increase the number of flocked hair, narrow the flocked hole pitch, etc., the flocked portion becomes hard and difficult to be applied. Problems such as scattering of the hair dye. Therefore, by optimizing the selection of each parameter so that the flocked portion 13 has the above-mentioned specific bending degree, it is possible to obtain a brush portion that is easy to apply and can suppress the scattering of the agent.

  In this hair dyeing applicator 1A, the base surface of the applicator main body on which the above-described comb teeth 12 and brush hairs 14 stand up, that is, the base surface 17 of the brush portion 10 is gently at the comb tooth portion 11 with respect to the flocked portion 13. It is characterized by protruding. This makes it easier for the hair dye to flow from the comb tooth portion 11 to the flocked portion 13 during hair dyeing, and prevents the hair dye from remaining unnecessarily in the comb tooth portion 11 after hair dyeing.

  The protrusion of the base surface 17 of the brush portion 10 is as shown in FIG. 1c. In the cross section of the brush portion perpendicular to the comb tooth row, the base surface 17a of the flocked portion 13 is substantially horizontal, and the comb tooth portion The base surface 17b of the brush 11 may have a chevron shape, or, as shown in FIG. 3, the base surface 17 swells in a semi-cylindrical shape from the edge of the brush portion 10 toward the center of the comb tooth portion 11. Alternatively, as shown in FIG. 4, the base surface 17 may be raised in a mountain shape in the entire brush portion 10, and various modes can be taken.

  If the degree of protrusion of the base surface 17 of the brush portion 10 is too large, the effect of the comb teeth 12 is reduced and the applicability is impaired, and if it is too small, the effect of projecting the base surface 17 cannot be obtained. 11, the height difference H3 between the highest level of the base surface 17b and the base surface at the edge of the brush portion 10 is preferably 3 mm to 6 mm. And the height difference between the tip of the comb teeth and the rigidity and flocking ratio of the brush hair, the prescription of the paste-like hair dye, and the viscosity.

  As a manufacturing method of this hair dyeing applicator 1A, the brush base 16 having the comb tooth portion 11, the handle 2, the comb portion 3, and the slice portion 4 are integrally molded with resin, and the comb tooth portion of the obtained molded product is obtained. What is necessary is just to plant the bristles 14 around 11. Here, it is preferable to use a highly transparent resin (for example, transparent polypropylene (PP), polyethylene naphthalate (PEN), polystyrene (PS), or the like) as the resin to be molded because the design can be improved.

  The hair dye applicator of the present invention can take various other forms. For example, the arrangement mode of the bristles 15 along the comb teeth row may be alternately shifted as shown in FIG. When shifting alternately, the distance D between adjacent bristle is set to the same level as in the embodiment shown in FIG. 1 so that the hair dye is appropriately held in the recess of the brush portion 10.

  Further, in order to facilitate partial dyeing of hair roots and the like, it is possible to use a brush as shown in FIG. 8 instead of arranging a plurality of bristles 15 at the tip of the brush portion 10. The flocking density of the bristles 14 may be increased by densifying the flocking pattern of the bristle 15 in the flocking part 13a at the tip of the part 10. Further, as shown in FIG. 9, at the tip portion of the brush portion 10, the region of the flocked portion 13 a may be enlarged in the tip direction of the brush portion 10, and the flocking density of the brush bristles 14 in this region may be increased.

In this case, by providing a constriction on the brush base 16 as shown in FIG. 10 or by giving R to the tip of the brush base 16 as shown in FIG. Further, as shown in FIG. 12, it may be possible to cope with more detailed application by forming the tip portion to be tapered.

  Further, like the hair dyeing applicator 1B shown in FIG. 13, the handle 2 may be molded separately on the comb portion 3 side and the slice portion 4 side, and these may be detachably fitted. . Thereby, the product of the hair dye applicator 1B can be packed compactly. In the hair dye applicator, the slice portion 4 may be omitted.

  Further, a hair dye discharge passage and a discharge hole are formed in the comb teeth 12 of the brush portion 10, and the discharge passage is communicated with a container such as an aerosol container or a squeeze container containing the hair dye. The hair agent may be discharged from the comb teeth.

  The hair dye applicator of the present invention is useful for applying a hair dye to hair.
