A plurality (15 in this embodiment) of outer brush teeth 12a are used. The outer brush teeth 12a have rigidity that does not bend when the hair treatment agent is applied to the hair. Since the outer brush teeth 12a of the outer brush tooth row 12 have such rigidity, it is possible to comb the hair preferably by moving the hair treatment brush 10 in the width direction Y of the brush base 11. The hair treatment agent can be efficiently mixed with the first agent 30a containing the alkaline agent and the second agent 30b containing the oxidizing agent by synergistic effects with the bending deformation of the inner brush teeth 13a as described later. Can be applied to the back side of the hair.

  Here, as will be described below, the outer brush teeth 12a can be selected by appropriately selecting the material, the cross-sectional shape, the cross-sectional dimensions, and the tip height of the outer brush teeth 12a. , It can have rigidity that does not flex.

  The material of the outer brush teeth 12a can be made of, for example, a material using polyethylene resin, polypropylene resin, ABS resin (acrylonitrile / butadiene / styrene copolymer synthetic resin) or the like, similar to the base portion 11c of the brush base 11. . In this embodiment, a material using polypropylene is used.

  Further, for example, the tensile elastic modulus of polypropylene resin is about 1000 to 2000 MPa (measured value according to JIS K7161, 7162: 1994), and is several times higher than the tensile elastic modulus of the elastomer used for the inner brush teeth 13a described later. 10 to several hundred times larger value.

  The cross-sectional shape of the outer brush teeth 12a can be a circle, an ellipse, a polygon, or the like. Further, different cross-sectional shapes may be provided in the height direction (direction Z perpendicular to the base surface 11b of the brush base 11). For example, the cross-sectional shape of the base portion of the outer brush tooth 12a can be circular, and the cross-sectional shape of the tip portion can be elliptical.

  The cross-sectional dimension (the diameter if the cross section is circular, the equivalent circle diameter if the cross section is non-circular) can be about 1 mm to 5 mm, for example. Moreover, you may provide the cross-sectional dimension different from a root part in the height direction (direction Z perpendicular | vertical with respect to the base surface 11b of the brush stand 11).

  The tip height of the outer brush teeth 12a (the height in the direction Z perpendicular to the base surface 11b of the brush base 11) is, for example, about 4 mm to 15 mm.

  In the present embodiment, the outer brush teeth 12a each have an elongated, substantially truncated cone shape having an outer diameter of, for example, about 1 mm and the tip processed into a spherical shape. For example, the height is set to be about 7 mm from the 11 base surface 11b. The cross-sectional shape of the outer brush teeth 12a is circular, the diameter of the root portion is about 2 mm, and the diameter of the tip portion is about 1 mm. Further, the outer brush teeth 12a are arranged in a line in a row with a predetermined interval in the length direction X of the brush base 11, for example, with an interval between the central axes c of 4 mm. Outer brush tooth rows 12 are formed on the side edges of both sides of the brush base 11 in the width direction Y, respectively.

  In addition, the preferable range of the space | interval between the center axis | shafts c in the length direction X of the brush stand 11 of several outer brush teeth 12a is about 1-6 mm.

  Further, in the present embodiment, the outer brush teeth 12 a constituting the outer brush tooth row 12 have the center axis c from the direction Z perpendicular to the base surface 11 b of the brush table 11 to the width direction Y of the brush table 11. Is preferably erected at an inclination angle θ of preferably 5 to 45 degrees, more preferably 5 to 30 degrees, and still more preferably 5 to 20 degrees. This makes it possible to place a larger amount of the hair treatment agent on the upper surface 11a of the brush base 11 and to apply the hair treatment agent to the hair while combing the hair. When the hair treatment brush 10 is slid and moved to Y, the outer brush teeth 12a serve as a guide, and the hair moves from the tip side of the outer brush teeth 12a to the brush base 11 side. It becomes possible to make it easier to contact. Further, when the hair treatment agent brush 10 is slid in the width direction Y of the brush base 11, the hair can stand up while the outer brush teeth 12a are in contact with the root of the hair, and the hair treatment agent is applied to the hair. It becomes possible to improve the property.

  Here, the base surface 11b of the brush base 11 is provided on the side edge portions on both sides in the width direction Y of the brush base 11, and the brush base 11 has the outer brush teeth 12a constituting the pair of outer brush tooth rows 12. It is a flat virtual reference plane obtained by connecting the standing base end portion on the upper surface 11a between the outer brush tooth rows 12 on both sides.

  A plurality of end brush tooth rows 15 provided at both ends in the length direction X of the brush base 11 are arranged at predetermined intervals in the width direction Y of the brush base 11 (this embodiment). In the embodiment, it is constituted by three end brush teeth 15a. As described above, the end brush teeth 15a are integrally formed with the base portion 11c of the brush base 11 so that the hair treatment agent is applied to the hair in the same manner as the outer brush teeth 12a of the outer brush tooth row 12. In this case, it has rigidity that does not flex.

  Here, as will be described below, the end brush teeth 15a, like the outer brush teeth 12a, are appropriately selected from materials, cross-sectional shapes, cross-sectional dimensions, and tip heights, so that the hair treatment agent is applied to the hair. When applied, it can have rigidity that does not flex.

  The material of the end brush teeth 15a can be made of, for example, polyethylene resin, polypropylene resin, ABS resin (acrylonitrile / butadiene / styrene copolymer synthetic resin) or the like. In this embodiment, a material using polypropylene is used.

  Further, for example, the tensile elastic modulus of polypropylene resin is about 1000 to 2000 MPa (measured value according to JIS K7161, 7162: 1994), and is several times higher than the tensile elastic modulus of the elastomer used for the inner brush teeth 13a described later. 10 to several hundred times larger value.

  As the cross-sectional shape of the end brush teeth 15a, a circle, an ellipse, a polygon, or the like can be adopted. Further, different cross-sectional shapes may be provided in the height direction (direction Z perpendicular to the base surface 11b of the brush base 11). For example, the cross-sectional shape of the root portion of the end brush tooth 15a may be circular, and the cross-sectional shape of the tip portion may be elliptical.

  The cross-sectional dimension (the diameter if the cross section is circular, the equivalent circle diameter if the cross section is non-circular) can be set to, for example, about 1 mm to 5 mm. Moreover, you may provide the cross-sectional dimension different from a root part in the height direction (direction Z perpendicular | vertical with respect to the base surface 11b of the brush stand 11).

  The tip height of the end brush teeth 15a (the height in the direction Z perpendicular to the base surface 11b of the brush base 11) is, for example, about 4 mm to 15 mm.

  In the present embodiment, each of the end brush teeth 15a of the end brush tooth row 15 has an outer diameter of, for example, about 1 mm, and the tip is processed into a spherical shape, like the outer brush teeth 12a of the outer brush tooth row 12. It is provided so as to stand upright so that the tip has a height of, for example, about 7 mm from the base surface 11 b of the brush base 11. The cross-sectional shape of the end brush teeth 15a is circular, the diameter of the root portion is about 2 mm, and the diameter of the tip portion is about 1 mm.

  Further, the end brush teeth 15a of the end brush tooth row 15 are arranged in a row, for example, with a predetermined interval in the width direction Y of the brush base 11, with an interval between the central axes of 4 mm, for example. As a result, the end brush tooth rows 15 are formed on both edges of the brush base 11 in the longitudinal direction X, respectively. The end brush teeth 15 a of the end brush tooth row 15 are provided upright in a direction Z perpendicular to the base surface 11 b of the brush base 11. Since the end brush tooth rows 15 are provided at both ends of the brush base 11 in the length direction X, as shown in FIG. In a region surrounded by the outer brush tooth rows 12 on both sides in the width direction Y of the table 11, an appropriate amount of the hair treatment agent can be easily placed on the upper surface 11 a of the brush table 11. Further, by providing the end brush tooth row 15, it is possible to prevent unintentional outflow of the placed hair treatment agent from the brush base 11.

  In addition, the preferable range of the space | interval between the center axis | shafts in the width direction Y of the brush stand 11 of the several edge part brush teeth 15a is about 1-6 mm.

  A plurality of inner brush tooth rows 13 provided inside the outer brush tooth row 12 adjacent to the width direction Y of the brush stand 11 are arranged at predetermined intervals in the length direction X of the brush stand 11. It is comprised by the inner brush tooth 13a by the elastomer of this (14 in this embodiment). The inner brush teeth 13a made of elastomer are integrally formed with the soft base portion 11d made of elastomer of the brush base 11 as described above. Since the inner brush teeth 13a of the inner brush teeth row 13 are made of an elastomer, when the hair treatment agent is applied to the hair, as shown in FIG. Since the inner brush teeth 13a bend to the opposite side, the hair treatment agent in the region sandwiched between the inner brush teeth 13a and the hair can be pushed into the hair from the surface of the hair one by one. Become. This also makes it possible to effectively apply the hair treatment agent to the back side of the hair.

  Further, when the hair treatment agent is applied to the hair, the hair treatment agent is applied to the outer brush teeth 12 by the outer brush teeth 12a having rigidity that does not flex and the hair between the plurality of outer brush teeth 12a. The hair treatment agent can be kept inside, and the hair treatment agent can be mixed more efficiently due to the synergistic effect with the bending operation of the inner brush teeth 13a.

  Here, as will be described below, the inner brush teeth 13a can be selected when the hair treatment agent is applied to the hair by appropriately selecting the material, cross-sectional shape, cross-sectional dimensions, and tip height of the inner brush teeth 13a. , Can have a bending stiffness.

  The material of the inner brush teeth 13a is an elastomer. In this embodiment, a styrene elastomer is used.

  Further, for example, the tensile elastic modulus of the styrene elastomer is about 5 to 50 MPa (measured value according to JIS K7113).

  As the cross-sectional shape of the inner brush teeth 13a, a circle, an ellipse, a polygon or the like can be adopted. Further, different cross-sectional shapes may be provided in the height direction (direction Z perpendicular to the base surface 11b of the brush base 11). For example, the cross-sectional shape of the root portion of the inner brush teeth 13a can be circular, and the cross-sectional shape of the tip portion can be elliptical.

  The cross-sectional dimension (the diameter if the cross section is circular, the equivalent circle diameter if the cross section is non-circular) can be set to, for example, about 1 mm to 5 mm. Moreover, you may provide the cross-sectional dimension different from a root part in the height direction (direction Z perpendicular | vertical with respect to the base surface 11b of the brush stand 11).

  The tip height of the inner brush teeth 13a (the height in the direction Z perpendicular to the base surface 11b of the brush base 11) is, for example, about 3 mm to 14 mm.

  In the present embodiment, the inner brush teeth 13a made of elastomer constituting the inner brush teeth row 13 each have an elongated substantially truncated cone shape having an outer diameter of, for example, about 1 mm and having a tip processed into a spherical shape. The front end of the brush base 11 is erected so as to have a height of about 6 mm, for example. The inner brush teeth 13a made of elastomer preferably have a tip height that is about 1 mm higher than the tip height of the outer brush teeth 12a of the outer brush teeth row 12 in the direction Z perpendicular to the base surface 11b of the brush base 11. Are provided so as to be low at a height difference h (see FIG. 4). The height of the tip of the inner brush tooth 13a made of elastomer is lower than the height of the tip of the outer brush tooth 12a of the outer brush tooth row 12, so that the outer brush tooth is not obstructed by the inner brush tooth 13a. The hair treatment agent can be applied to the hair while combing the hair in the row 12. In addition, the hair treatment agent can be applied to the hair along the curvature of the head. From this point of view, the inner brush teeth 13a have a tip height in the direction Z perpendicular to the base surface 11b of the brush base 11 of 0.5 to 10 mm higher than the tip height of the outer brush teeth 12a. It is preferable that they are provided upright so as to be lowered at the height difference h.

  Furthermore, in the present embodiment, the inner brush teeth 13 a made of elastomer constituting the inner brush tooth row 13 are set at a predetermined interval in the length direction X of the brush base 11, similarly to the outer brush teeth 12 a of the outer brush tooth row 12. For example, a plurality of lines are arranged in a line at intervals of the central axis c ′ of 4 mm. As a result, a pair of inner brush tooth rows 13 are formed adjacent to the inside of the outer brush tooth row 12 at the side edge portions on both sides in the width direction Y of the soft base portion 11 d of the brush base 11. . Further, the inner brush teeth 13 a made of elastomer are shifted from the outer brush teeth 12 a of the outer brush tooth row 12 by half the pitch of the adjacent outer brush teeth 12 a in the length direction X of the brush base 11. Are arranged in a staggered pattern. Thus, the inner brush teeth 13 a made of elastomer are arranged so that the central axis c ′ does not overlap the central axis c of the outer brush teeth 12 a of the outer brush tooth row 12 in the width direction Y of the brush base 11. . The center axis c ′ of the inner brush teeth 13 a made of elastomer is preferably arranged so as not to overlap the center axis c of the outer brush teeth 12 a and the width direction Y of the brush base 11. As shown in FIG. 6, the hair treatment agent is moved in the width direction Y of the brush base 11 so that the hair treatment agent does not interfere with the outer brush teeth 12a and the inner brush teeth 13a when the hair treatment agent is applied to the hair. It is possible to bend the inner brush teeth 13a on the opposite side to the direction M in which the brush 10 is moved.

  Furthermore, in the present embodiment, the inner brush teeth 13a made of elastomer constituting the inner brush teeth row 13 have a tip portion 13b that is a space between each pair of outer brush teeth 12a adjacent to the outer brush teeth row 12. Thus, it is formed so as to be deformable until it protrudes to the outside of the brush tooth row 12 (see FIGS. 4 and 7). The inner brush teeth 13a made of elastomer of the inner brush tooth row 13 can be deformed until the tip end portion 13b protrudes outside the outer brush tooth row 12 through the space between the adjacent outer brush teeth 12a. Accordingly, as shown in FIG. 7, the side portions of the outer brush teeth 12 a and the side surfaces of the inner brush teeth 13 a are deformed until the tip portion 13 b of the inner brush teeth 13 a protrudes outward of the outer brush tooth row 12. In between, the subdivided hair can be sandwiched, which makes it possible to more effectively spread the hair treatment agent to the back side of the hair.

  A plurality of intermediate brush teeth rows 14 provided at intermediate portions between the inner brush teeth rows 13 on both sides are arranged at predetermined intervals in the length direction X of the brush base 11 (this embodiment). In this case, the intermediate brush teeth 14a are made of 13) elastomer. The intermediate brush teeth 14a made of elastomer are integrally formed with the soft base portion 11d made of elastomer of the brush base 11 as described above. When the hair treatment agent is applied to the hair, the middle brush tooth 14a made of elastomer in the middle brush tooth row 14 moves the hair treatment brush 10 as shown in FIG. 6 in the same manner as the inner brush tooth 13a. It bends in the direction opposite to the direction M. As a result, like the inner brush teeth 13a, the hair treatment agent sandwiched between the intermediate brush teeth 14a and the hair can be pushed in between each hair from the hair surface to the back side of the hair. It becomes possible to apply the hair treatment agent effectively.

  Here, as will be described below, the intermediate brush tooth row 14 is made of a hair treatment agent by appropriately selecting a material, a cross-sectional shape, a cross-sectional dimension, and a tip height in the same manner as the inner brush tooth 13a. When it is applied, it can have a bending rigidity.

  The material of the intermediate brush teeth 14a is an elastomer. In this embodiment, a styrene elastomer is used.

  Further, for example, the tensile elastic modulus of the styrene elastomer is about 5 to 50 MPa (measured value according to JIS K7113).

  As the cross-sectional shape of the intermediate brush teeth 14a, a circular shape, an elliptical shape, a polygonal shape, or the like can be adopted. Further, different cross-sectional shapes may be provided in the height direction (direction Z perpendicular to the base surface 11b of the brush base 11). For example, the cross-sectional shape of the root portion of the intermediate brush teeth 14a may be circular, and the cross-sectional shape of the tip portion may be elliptical.

  The root partial cross-sectional dimensions of the intermediate brush teeth 14a (diameter if the cross section is circular, equivalent circle diameter if non-circular) can be, for example, about 1 mm to 5 mm. Moreover, you may provide the cross-sectional dimension different from a root part in the height direction (direction Z perpendicular | vertical with respect to the base surface 11b of the brush stand 11).

  The tip height of the intermediate brush teeth 14a (the height in the direction Z perpendicular to the base surface 11b of the brush base 11) is, for example, about 2 mm to 10 mm.

  In the present embodiment, the intermediate brush teeth 14a constituting the intermediate brush tooth row 14 each have a vertically long substantially truncated cone shape having an outer diameter of, for example, about 1 mm and having a tip processed into a spherical shape. The front end of the brush base 11 is provided to stand up to a height of about 5 mm, for example. The intermediate brush teeth 14a preferably have a tip height in a direction Z perpendicular to the base surface 11b of the brush base 11 rather than the tip height of the inner brush teeth 13a constituting the inner brush tooth row 13. It is erected so as to be about 0.5 to 2 mm lower. By making the height of the tip of the intermediate brush teeth 14a lower than the height of the tip of the inner brush teeth 13a, the hair treatment agent can be stably placed on the upper surface of the brush base 11.

  Further, in the present embodiment, the intermediate brush teeth 14 a constituting the intermediate brush tooth row 14 are set at predetermined intervals in the length direction X of the brush base 11, similarly to the inner brush teeth 13 a of the inner brush tooth row 13. For example, a plurality of lines are arranged in a line at intervals of a central axis of 4 mm. As a result, an intermediate brush tooth row 14 is formed at the central portion of the soft base portion 11 d of the brush base 11. Further, the intermediate brush teeth 14a are shifted from the inner brush teeth 13a of the inner brush teeth row 13 by half the pitch of the adjacent inner brush teeth 13a in the length direction X of the brush base 11, Arranged in a staggered pattern.

  An intermediate brush tooth row 14 is provided at an intermediate portion between the inner brush tooth rows 13 on both sides, and the intermediate brush teeth 14a are arranged in a staggered manner with respect to the inner brush teeth 13a. As shown in FIG. 6, the intermediate brush on the opposite side to the direction M in which the hair treatment agent brush 10 is moved is produced without causing the inner brush teeth 13a and the intermediate brush teeth 14a to interfere with each other. The teeth 14a can be bent, and it becomes possible to improve the mixability of the hair treatment agent sandwiched between the intermediate brush teeth 14a and the hair, and the hair treatment agent can be removed one by one from the surface of the hair. It can be pushed into the hair. This makes it possible to effectively apply the hair treatment agent to the back side of the hair.

  In addition, since the intermediate brush tooth row 14 is provided in the middle portion between the inner brush tooth rows 13 on both sides, the hair treatment agent placed on the upper surface of the brush base 11 is transferred to the inner brush tooth row 13. And the intermediate brush teeth row 14 are in contact with each other, so that it is possible to improve the retention of the hair treatment agent on the upper surface of the brush base 11.

  In addition, the region between the inner brush tooth row 13 and the intermediate brush tooth row 14 in the width direction Y of the brush base 11 is a region where no brush teeth are present. It can be used as a mark for placement, and is preferable from the viewpoint that the hair treatment agent can be stably placed on the upper surface of the brush base.

  Further, in the width direction Y of the brush base 11, the region between the inner brush tooth row 13 and the intermediate brush tooth row 14 is a region where no brush teeth exist, as shown in FIG. It is possible to bend the intermediate brush teeth 14a on the side opposite to the direction M in which the hair treatment brush 10 is moved without being buffered with other brush teeth, whereby the intermediate brush teeth 14a and the hair It becomes possible to further improve the mixing property of the hair treatment agent sandwiched between the two.

  The width w of the region in the width direction Y of the brush base 11 (the width between the side surfaces of the brush teeth at the base portion of the inner brush tooth row 13 and the intermediate brush tooth row 14, see FIG. 3) is preferably 3 to 8 mm. 3 to 6 mm is more preferable. In this embodiment, it is 4 mm.

  In order to apply the hair treatment agent (hair dye) to the hair and treat it (hair dyeing) using the hair treatment brush 10 having the above-described configuration, the user grips the handle portion 24 by hand, for example. Then, with the brush part 22 (hair treatment agent brush 10) of the hair treatment tool 20 facing upward, for example, a double aerosol container described in JP-A No. 2002-119328 or JP-A No. 2003-205938 From the hair dye which is a two-component hair treatment agent, for example, a first agent containing an alkaline agent and an oxidation dye, and a second agent containing hydrogen peroxide which is an oxidizing agent, preferably in a cream form As shown in FIG. 5, the discharged first agent and second agent are extended in the length direction X of the brush base 11 and the width direction Y of the brush base 11 by discharging in the form of foam. The upper surface 11 of the brush base 11 in a state where To be placed on. As a result, the quality and amount of each of the first agent and the second agent before mixing can be easily confirmed visually.

  Thereafter, the user operates the hair treatment tool 20 so that the hair treatment brush 10 on which the first agent and the second agent are placed is opposed to the hair, and for example, by the comb portion 21 of the hair treatment tool 20. The hair treatment agent brush 10 is preferably slid in the width direction Y of the brush base 11 in a state where the hair treatment brush 10 is pressed along the divided hair.
