  As a result of further research after the patent application relating to Patent Document 3, the applicant of the present application has a long time when sebum is present on the protrusion when the protrusion has an elastomer resin like the scalp massage brush described in Patent Document 3. It has been found that if left as it is, sebum permeates into the elastomer, and the projections are likely to wear during subsequent use of the brush. In particular, like the scalp massage brush shown in FIG. 1 and FIG. 2 of Patent Document 3, a spatula-shaped protrusion that is arranged at the center of the brush and actively scrapes off dirt such as sebum clogged in pores. Depending on the usage environment, wear may progress and the protrusions of other parts may be relatively less worn, such as by pressing the brush strongly against the head and not cleaning the brush after use. There was a need to replace the brush. Also, the brush replacement time varies greatly depending on the subjectivity of the user of the brush, so the brush can be replaced at an early stage even though it can fully perform the function of removing sebum and cleaning pores. Even though their functions are considerably lowered, there is a disadvantage that they continue to use without noticing it.

  The objective of this invention is providing the brush for scalp massage which can recognize the appropriate replacement | exchange time of a brush easily.

  The present invention provides a spatula-like projection made of an elastomer resin having a flat cross-sectional shape, and a plurality of tip projections standing at the tip portion at intervals in the long axis direction of the flat cross-sectional shape. A plurality of cone-shaped protrusions made of an elastomer resin are scalp massage brushes protruding from the brush surface of the base, and a plurality of the spatula-shaped protrusions are spaced from each other at a central portion of the brush surface. A central projection group arranged in series, and the cone-shaped projections are arranged on both sides of the central projection group, the cone-shaped projection comprising a truncated cone-shaped base and a tip of the base And a scalp massage brush having an indicator projection for notifying the replacement timing of the brush by disappearance or reduction.

  According to the scalp massage brush of the present invention, an excellent massage effect is obtained, an excellent sebum removing function and a pore cleaning function are exhibited, and an appropriate replacement time of the brush can be easily recognized. That is, the presence of the central projection group actively removes sebum and cleans pores, while the amount of sebum adhering to the indicator projections of the cone-shaped projections is relatively reduced, so that the inside of the elastomer It is possible to prevent sebum from penetrating and the protrusions from being easily worn when the brush is used thereafter, and to recognize an appropriate replacement time of the brush.

Hereinafter, the present invention will be described based on preferred embodiments thereof.
A scalp massaging brush 10 according to a preferred embodiment of the present invention shown in FIGS. 1 and 2 has a spatula-shaped protrusion 14 of different shapes made of an elastomer resin on a brush surface 13 of a base 12 having a grip 11. A plurality of conical projections 15 are provided in a standing manner. Standing means to stand in a standing state.

  The scalp massage brush 10 of the present embodiment has a gripping part 11 sandwiched between fingers, for example, when shampooing or maintaining the hair, and the palm of the hand is brought into close contact with the upper surface of the base 12 opposite to the brush surface 13. Then, the brush 10 is gripped while covering the upper surface, and the hairs are scraped in a state where the tips of the plurality of spatula-shaped projections 14 and the cone-shaped projections 15 standing on the brush surface 13 are pressed against the scalp. In addition, by moving the brush 10, it is possible to efficiently remove the sebum and clean the pores in combination with the action of the detergent, hair care agent, cosmetics, etc. applied to the scalp and hair as necessary. At the same time, an excellent massage effect can be obtained.

  Each of the spatula-shaped protrusions 14 is made of an elastomer resin and has a flat cross-sectional shape, and a plurality of front-end protrusions 14b at the respective front end portions are in the major axis direction X (see FIG. 2) of the flat cross-sectional shape. Are arranged upright at intervals. Each of the cone-shaped protrusions 15 is made of an elastomer resin and has a cone-shaped shape. The conical shape includes a shape having a small protrusion at the tip of the base of the truncated cone.

The base 12 is a plastic molded product made of, for example, polyethylene, polypropylene, etc. As shown in FIG. 3, the bottom surface is opened as an elliptical mounting opening 17a, and the top surface is a smooth curved convex surface. Further, for example, the base body 17 having an elliptical shape in plan view having a major axis length of about 80 to 100 mm and a minor axis length of about 70 to 90 mm, and the mounting opening 17a of the base body 17 are closed. And a substrate 18 to be fitted and fixed.
The base body 17 is provided with a mounting recess 17b for mounting a bottom plate portion 19a of an elastomer molded body 19 to be described later, with the mounting opening 17a opening on the bottom surface side. On the upper surface of 17, a grip portion 11 that protrudes upward in a shape of a high wave and warps backward is provided at the front portion of the base body 17.

  The substrate 18 has an elliptical shape in plan view that substantially matches the opening shape of the mounting opening 17a of the base body 17, and the peripheral end surface 18a formed in the protruding shape is used as the opening edge of the mounting opening 17a. The base body 17 is fixed to the base body 17 by being engaged with a locking groove 17 c provided on the inner peripheral surface of the base body 17 along the surface. A plurality of elliptical projection holes 20 and a plurality of circular projection holes 21 are formed in the substrate 18 so as to correspond to the positions of the spatula-shaped projections 14 and the cone-shaped projections 15 described later (see FIGS. 2 and 4). . The lower surface of the substrate 18 serves as the bottom surface of the base 12 to form the brush surface 13, and a plurality of spatula-shaped protrusions 14 and cone-shaped protrusions 15 protrude from the brush surface 13. Therefore, the brush surface 13 also has an elliptical shape in plan view like the substrate 18.

Then, the substrate 18 is fitted and fixed so as to cover the mounting opening 17 a of the base body 17. At this time, the plurality of spatula-like protrusions 14 and the plurality of cone-like protrusions 15 that are integrally formed protruding from the bottom plate portion 19a of the elastomer molded body 19 are inserted into the plurality of elliptical protrusion holes 20 and the plurality of circular protrusion holes 21, respectively. Has been. Further, the bottom plate portion of the elastomer molded body 19 is disposed between the substrate 18 and a support rod 17d (see FIG. 3) that hangs from the inner top surface portion of the mounting recess 17b of the base body 17 and the peripheral step 17e of the mounting recess 17b. 19a is sandwiched. As a result, the elastomer molded body 19 has a plurality of spatula-like projections 14 and a plurality of cone-like projections 15 protruding downward from the lower surface of the substrate 18 constituting the brush surface 13 of the scalp massage brush 10, respectively. The portion 19a is attached to the base 12 in a state where the portion 19a is housed and fixed in the mounting recess 17b.

  The elastomer molded body 19 is a resin molded product formed using, for example, an olefin elastomer, a styrene elastomer, a polyester elastomer, a urethane elastomer, or the like as an elastomer resin, and is the same as the mounting opening 17a of the base body 17. It consists of a plate-like bottom board portion 19a having an elliptical planar shape, and a plurality of spatula-like projections 14 and a plurality of cone-like projections 15 protruding integrally from the bottom board portion 19a. As described above, the elastomer molded body 19 is attached to the base body 17 in a state where the base 19a is accommodated and fixed in the mounting recess 17b, and the spatula-like protrusion 14 and the cone-like protrusion 15 are removed from the brush surface 13 by the substrate 18. It protrudes at a desired height described later. Here, the elastomer resin for forming the elastomer molded body 19 is, for example, in conformity with hardness (Shore A hardness, rubber hardness meter (GS709N type A) ASTM D2240A 0-100 (Shore A hardness) manufactured by Teclock Co., Ltd.). It is preferable to use a material having a numerical value of 40-80. By using a material of such a material as the elastomer resin for forming the elastomer molded body 19, the spatula protrusion 14 and the cone-shaped protrusion 15 can be pressed against the scalp with a pressure that does not damage the scalp and is not painful. . Therefore, it is possible to give an appropriate stimulus, an excellent massage effect is obtained, and in combination with the action of a cleaning agent applied to the scalp and hair as necessary, removal of sebum and washing of pores is possible. It becomes possible to perform efficiently. In addition, when using the scalp massage brush 10 with a shampoo and a hair restorer, it is preferable to form the elastomer molded body 19 using an olefin-based elastomer or a styrene-based elastomer that is excellent in chemical resistance against these.

  In order to improve the cleanliness of the scalp massage brush, it is preferable to use a transparent or translucent elastomer molded body. In order to make the elastomer molded body transparent or translucent, it is necessary to select a transparent or translucent elastomer itself and to add small amounts of various additives (for example, anti-wear additives). As the degree of transparency, the haze value specified by JIS K7136 is preferably 5 to 30%, more preferably 10 to 20%, and still more preferably 13 to 17%. While being able to improve, the moderate durability of a brush can be maintained. As a specific elastomer molded product, trade name elastomer AR (the hardness 55-60) which is a styrene-based elastomer of Aron Kasei Co., Ltd. corresponds.

  The spatula-shaped protrusion 14 has a flat elliptical shape in which the cross-sectional shape of the root portion along the brush surface 13 is, for example, a length of a major axis of about 5 to 20 mm and a length of a minor axis of about 2 to 15 mm. (See FIG. 2), and as shown in FIGS. 5 (a) and 5 (b), the shape is slightly tapered toward the tip while maintaining a substantially similar cross-sectional shape. It consists of a spatula-like portion 14a and three tip projections 14b that protrude further upward from the tip of the spatula-like portion 14a. The spatula-like projection 14 is erected so that the height h1 from the brush surface 13 to the tip of the tip projection 14b is, for example, 5 to 25 mm, preferably 10 to 20 mm, and the height h2 of the spatula 14a is It occupies 70 to 95% of the height h1 to the tip of the tip projection 14b, and the spatula 14a is a main part of the spatula projection 14. As a result, the function of scraping the hair is efficiently exhibited, and the force is easily transmitted to the tip portion when pressed against the scalp.

The tip projection 14b provided at the tip portion of the spatula projection 14 has, for example, a substantially conical shape with the tip formed in a convex curved shape, and is, for example, 1 to 5 mm, preferably 2 from the tip of the spatula portion 14a. Projecting at a height h3 of more than 5 mm, and in the major axis direction X of the flat cross-sectional shape of the spatula-shaped protrusion 14, for example, the interval s1 at the root portion is 0 to 5 mm, the interval s2 at the top portion is 1 to 7 mm, preferably Three each of the spatula-shaped protrusions 14 are arranged upright at intervals of 2 to 5 mm. The ratio (h3 / d) between the height h3 of the tip protrusion 14b and the thickness (diameter) d at the root portion is preferably 0.4 to 2.5, and preferably 1.0 to 2.0. It is further preferable that
By setting the ratio of the height h3 of the tip protrusion 14b to the thickness d at the root portion to be 0.4 to 2.5, when pressed against the scalp, it becomes easy to reach the scalp and pores while scraping the hair. Thus, a better sebum cleaning effect is exhibited, and a more excellent massage effect can be obtained by appropriate stimulation. In particular, the ratio of the height h3 of the tip protrusion 14b to the thickness d at the root portion is set to 2.5 or less, and by suppressing the height of the tip protrusion 14b, the force is effectively transmitted through the tip protrusion 14b. In addition to being easily transmitted, bending and bending are less likely to occur, hair entanglement is reduced, and entangled hair can be easily removed. The thickness d of the tip protrusion 14b means the diameter when the cross-sectional shape at the root portion is circular, and doubles the secondary radius of the cross-section when the cross-sectional shape is not circular.

  As for the cone-shaped projection 15, the cross-sectional shape of the base portion along the brush surface 13 is a circle having a diameter of about 4 to 10 mm, for example (see FIG. 2), and as shown in FIG. A frustoconical base portion 15a that is slightly tapered toward the tip while maintaining a substantially similar cross-sectional shape, and a plurality of indicator projections 15b and 15c that protrude further upward from the tip of the base portion 15a, Consists of. The cone-shaped protrusion 15 is erected so that the height h4 from the brush surface 13 to the tips of the indicator protrusions 15b and 15c is, for example, 5 to 25 mm, preferably 10 to 20 mm, and the truncated cone-shaped base 15a. The height h5 occupies 90 to 98% of the height h4 from the brush surface 13 to the tips of the indicator protrusions 15b and 15c, and the base portion 15a is the main part of the cone-shaped protrusion 15.

In this embodiment, as shown in FIGS. 6, 7A and 7B, the indicator protrusion has two types of tip protrusions, that is, a first tip protrusion 15b and a second tip protrusion 15c. ing.
The tip projections 15b and 15c serving as indicator projections have a projection height h6 (see FIG. 6) from the tip of the truncated cone-shaped base 15a that is higher than the height h3 of the tip projection 14b of the spatula projection 14. It is low. As a result, the tip protrusion 14b of the spatula-like protrusion 14 is flexibly deformed to exert an excellent sebum removal function and pore cleaning function, while the disappearance or reduction of the tip protrusions 15b and 15c of the cone-shaped protrusion 15 is visually observed. Recognition. And these front-end | tip protrusions 15b and 15c function effectively as an indicator protrusion which notifies the replacement time of a brush. Furthermore, the amount of sebum attached to the tip projections 15b, 15c of the cone-shaped projection 15 can be relatively reduced, the sebum penetrates into the elastomer, and the projection is likely to be worn during subsequent use of the brush. It is possible to suppress the occurrence of the change and to recognize an appropriate replacement time of the brush.
The protrusions 15b and 15c serving as indicator protrusions have a protrusion height h6 (see FIG. 6) of 70% or less of the height h3 (see FIG. 5A) of the tip protrusion 14b of the spatula protrusion 14. It is preferably 10 to 50%, more preferably 15 to 40%. Further, the height h6 of each of the tip protrusions 15b and 15c is preferably 0.3 to 20 mm, more preferably 0.3 to 10 mm, still more preferably 0.3 to 5 mm, particularly It is preferable to set it as 0.5-1.5 mm.
In the present embodiment, the first tip protrusion 15b and the second tip protrusion 15c have the same protrusion height h6 from the tip of the base portion 15a. When tip projections having different heights exist at the tip of the base portion 15a, the height of the highest tip projection is set as the height h6 of the tip projection provided at the tip of the cone-like projection 15, and the spatula-like projection 14 Comparison is made with the height of the tip protrusion 14b (the average value when the tip protrusion 14b has a different height).

  As shown in FIGS. 7A and 7B, the first tip protrusion 15b in the present embodiment has a hemispherical shape and is disposed at the center of the tip of the truncated cone-shaped base portion 15a. On the other hand, the second tip protrusion 15c has a substantially hemispherical shape. More specifically, the root portion has a columnar shape, and the tip has a hemispherical convex curved surface. A plurality of second tip protrusions 15c are formed so as to surround the periphery of the first tip protrusion 15b. The number of second tip projections 15c surrounding the first tip projection 15b can be, for example, about 3 to 10, preferably 4 to 10, and more preferably 5 to 8. The plurality of second tip protrusions 15c are preferably arranged at substantially equal intervals around the first tip protrusion 15b. By providing a plurality, particularly three or more of the second tip protrusions 15c so as to surround the central portion, the tip protrusions can be worn regardless of the brush moving direction when using the brush. It becomes easy to visually recognize the disappearance or decrease of the tip protrusion 15c.

In the second tip protrusion 15c in the present embodiment, the thickness d2 of the root portion is smaller than the thickness d1 of the root portion of the first tip protrusion 15b. The thicknesses d1 and d2 of the tip protrusions 15b and 15c mean a diameter when the cross-sectional shape at the root portion is circular, and double the cross-sectional secondary radius when it is not circular.
The first tip protrusion 15b has a ratio (h6 / d1) of the protrusion height h6 from the tip of the base portion 15a to the thickness (diameter) d1 at the root portion of 0.3 to 0.85. Preferably, it is 0.5 to 0.75. In addition, the second tip protrusion 15c has a ratio (h6 / d2) between the protrusion height h6 from the tip of the base portion 15a and the thickness (diameter) d2 at the base portion of 0.5 to 2.0. It is preferable that the ratio is 0.7 to 1.5.
Further, the second tip protrusion 15c has an interval S3 (see FIG. 7B) between the second tip protrusions 15c adjacent to each other around the first tip protrusion 15b, 0.3 to 2 mm, and the top portion. It is preferable that the distance S4 (see FIG. 7B) is set to 2.5 to 4 mm.

In the present embodiment, the amount of deflection measured by applying a force to the tip protrusion 14b provided on the spatula protrusion 14 in the long axis direction X of the flat cross-sectional shape of the spatula protrusion 14 is indicated by an indicator. It is larger than the amount of deflection measured by applying the same force to the protrusions 15b and 15c from the same direction. As a result, the tip protrusion 14b of the spatula-shaped protrusion 14 is flexibly deformed to exert an excellent sebum removing function and pore cleaning function, while the cone-shaped protrusion 15 is relatively stably standing up. The massage effect by the body protrusion 15 is improved, and the tip protrusions 15b and 15c disappear or decrease relatively quickly, and the function as an indicator protrusion is also improved. Furthermore, the amount of sebum attached to the tip projections 15b, 15c of the cone-shaped projection 15 can be relatively reduced, the sebum penetrates into the elastomer, and the projection is likely to be worn during subsequent use of the brush. It is possible to suppress the occurrence of the change and to recognize an appropriate replacement time of the brush.
When measuring these deflection amounts, with the brush surface fixed horizontally, a force of 200 gf parallel to the brush surface is applied to the central portion in the height direction of the tip protrusion 14b or indicator protrusion 15b, 15c, Measure the distance traveled by the applied point. The greater the travel distance, the greater the amount of deflection. In measurement, it is preferable to fix the portion with a plate-like object or the like so that the spatula-like portion 14a of the spatula-like projection 14 and the truncated cone-like base portion 15a of the cone-like projection 15 do not bend.

In the present embodiment, as shown in FIG. 2, the brush surface 13 of the base 12 is substantially uniformly distributed over the entire surface, and the spatula-like protrusions 14 are 16 places and the cone-like protrusions 15 are 8 places. Respectively.
In the present embodiment, four spatula-shaped protrusions 14 are arranged at a central portion of the brush surface 13 with a central protrusion group 14R arranged in series at intervals, and are provided on both sides of the central protrusion group 14R. Conical protrusions 15 and 15 are arranged with the central protrusion group 14R interposed therebetween.
Further, in the present embodiment, the spatula protrusions 14 are erected at 12 locations on the outer peripheral portion along the peripheral edge of the brush surface 13 of the base 12. The spatula-like projections 14 constituting the central projection group 14R are provided in a row in a row so as to cross the central portion of the inner region 22 surrounded by the spatula-like projections 14 on the outer peripheral portion. The cone-shaped projections 15 are erected on the both sides of the central projection group 14R and in an inner region 22 surrounded by the spatula-shaped projections 14 on the outer peripheral portion.

  In the present embodiment, the “center portion of the brush surface 13” means “on the major axis of the brush surface 13 having an elliptical shape in plan view”, and the “both sides of the central protrusion group 14R” means “ This means “both sides of the center protrusion group 14R in the short axis direction of the brush surface 13 having an elliptical shape in plan view”.

  Furthermore, in the present embodiment, the 16 spatula-shaped protrusions 14 are erected so that the major axis direction X of the flat cross-sectional shape is parallel to the minor axis direction of the elliptical brush surface 13. ing. The spatula-shaped protrusions 14 are erected so that the long axis direction X of the flat cross-sectional shape is directed in the same direction, so that it is possible to effectively avoid hair adhesion and entanglement, and hair If the scalp massage brush 10 is moved in the short axis direction of the brush surface 13, the function of scratching the scalp and hair is improved.

  Furthermore, the height h2 of the spatula-like portion 14a of the spatula-like projection 14 is set lower than the height h5 of the truncated cone-like base portion 15a of the cone-like projection 15, and the height h3 of the tip projection 14b of the spatula-like projection 14 is set. By setting the height h6 of the first and second tip projections of the cone-like projection 15 higher than the height h6, the tip projection 14b of the spatula projection 14 pressed against the scalp is used when the scalp massage brush 10 is used. Therefore, dirt such as sebum clogged in the pores can be scraped out positively. On the other hand, the indicator protrusions 15b and 15c of the cone-shaped protrusion 15 can be pressed against the scalp almost without bending, and therefore the amount of sebum attached to the tip protrusions 15b and 15c can be relatively reduced. Further, it is possible to prevent sebum from penetrating into the elastomer and prevent the protrusions from being easily worn during the subsequent use of the brush, and to recognize an appropriate replacement time of the brush.

  Further, the brush of the present invention has a central protrusion group 14R in which a plurality of spatula-shaped protrusions 14 are arranged in series at intervals in the center portion of the brush surface, and a conical shape on each side of the central protrusion group. Since the protrusions 15 are arranged, the brush can exhibit the following effects. That is, since the plurality of spatula-shaped protrusions 14 are arranged in series at the central portion of the brush surface and form the central protrusion group 14R, the scalp can be contacted more strongly, and has excellent sebum removal function and pores. The cleaning function is demonstrated. This is because the contour shape of the head is not flat. On the other hand, since the cone-shaped projections 15 are arranged on both sides of the central projection group 14R, the indicator projections 15b and 15c of the cone-shaped projection 15 can be pressed against the scalp almost without bending. Therefore, the amount of sebum attached to the tip protrusions 15b, 15c can be relatively reduced, the sebum can penetrate into the elastomer, and the protrusion can be prevented from being easily worn during the subsequent use of the brush, Appropriate replacement time of the brush can be recognized.

  Furthermore, in the present embodiment, as shown in FIGS. 3 and 4, the tip of the tip projections 14b of the plurality of spatula projections 14 and the tip of the indicator projections 15b and 15c of the plurality of cone-like projections 15 are connected. The continuous surface S is a concave curved surface that is recessed inward along the contour shape of the head. If the tip continuous surface S is a flat surface, the wear amount of the central projection group 14R may be relatively large depending on the usage state of the scalp massage brush. On the other hand, by making the tip continuous surface S into a concave curved surface, it is possible to suppress variations in the degree of wear of the tip portions of the plurality of spatula-like protrusions 14 and the plurality of cone-like protrusions 15, and excellent sebum It is possible to maintain a state where the function of removing the pores and the function of cleaning the pores are exhibited for a long period of time.

  The radius of curvature of the concave curved surface can suppress variation in the degree of wear of the tip portions of the plurality of spatula-shaped protrusions 14 and the plurality of cone-shaped protrusions 15, and has an excellent sebum removal function and pore cleaning. From the viewpoint that the state where the function is exhibited can be maintained for a long time, 150 to 400 mm is preferable in the major axis direction of the brush surface, and 180 to 350 mm is preferable in the minor axis direction of the brush surface.

  In the scalp massage brush 10 of the present embodiment having the above-described configuration, for example, the grip portion 11 is sandwiched between fingers, and the palm is brought into close contact with the upper surface of the base 12 opposite to the brush surface 13. The brush 10 is gripped while covering the upper surface, and the hair is scraped in a state where the tips of the plurality of spatula-like projections 14 and the cone-like projections 15 standing on the brush surface 13 are pressed against the scalp. By moving 10, hair washing and hair care are performed while applying a cleaning agent, a hair care agent, cosmetics and the like to the scalp and hair as necessary. Here, the grip portion 11 has a concave shape along the shape of the side surface of the finger, and the grip portion 11 is gripped in a stable state while fitting the brush 10 to the hand, for example, for scalp massage.

The code | symbol 37 has shown the back surface side of the blister container.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, a spatula-like projection is erected on the outer peripheral portion along the periphery of the brush surface, and a cone-like projection is erected on these inner regions, or a row of spatula projections is formed across the central portion of the inner region. It is not always necessary to provide a plurality of spatula-like protrusions and a plurality of cone-like protrusions on the entire brush surface. The spatula-shaped protrusion may have an elliptical cross-sectional shape or other flat cross-sectional shape such as an ellipse or a rectangle, and the cone-shaped protrusion has a substantially conical shape or a pyramid shape. Etc. Furthermore, two or four or more tip protrusions can be provided on the spatula-like protrusion, and the tip protrusion may have a shape other than the conical shape.
The number of the spatula-shaped protrusions 14 constituting the central protrusion group 14R may be 3 or 5 or more. Further, the central protrusion group 14R may be one in which the spatula protrusions 14 are arranged in series in the major axis direction of the elliptical brush surface 13 or may be one in which the spatula protrusions 14 are arranged in series in the minor axis direction. good.

  Moreover, as an indicator protrusion, as shown in FIG. 9, a cylindrical portion 15d having a diameter smaller than the diameter of the distal end portion 15a ′ of the base portion 15a, and a diameter larger than that of the cylindrical portion 15d. There may be provided a tip projection 15g having a small conical portion 15e having a bottom portion 15e 'having a diameter larger than that of the tip portion 15a' of the base portion 15a. The tip protrusion 15g shown in FIG. 9 is provided in a state in which a cylindrical portion 15d is connected to the tip of the base portion 15a. The tip projection 15g as the indicator projection shown in FIG. 9 is a guideline when the cylindrical portion 15d is broken and the small conical portion 15e is removed from the base portion 15a (corresponding to the disappearance of the tip portion described above). It is preferable to replace the brush with a new one.

  Note that, similarly to the tip projections 15b and 15c of the cone-like projection 15 in FIG. 7A, the tip projection 15g can also have an indicator projection function that informs the brush replacement timing of disappearance or reduction due to wear.

  In the scalp massage brush 10 described above, the spatula portion 14a of the spatula projection 14 and the tip projection 14b are integrally formed of the same material, and the base portion 15a of the cone-like projection 15 and the first and second tip projections. 15b and 15c are integrally formed of the same material, but the tip protrusion 14b and the first and second tip protrusions 15b and 15c manufactured independently are later heat-sealed to the spatula portion 14a and the base portion 15a. May be integrated.
