The present invention relates to a scalp massage brush, and more particularly to a scalp massage brush having a plurality of protrusions made of an elastomer resin on a brush surface of a base.

As a hairbrush used for shampooing or combing hair, various forms are known, for example, a spherical body is provided at the front end of the bristle-like protrusion constituting the brush, or has a substantially conical protrusion, or has a different thickness and A combination of length protrusions, etc. In addition, in recent years, there has also been developed a massage brush which has the functions of scratching the scalp, scratching the function of the hair, or smoothing the function of the entangled hair, and removing the sebum which becomes a cause of dirt or bad odor, or the function of cleaning the pores. It is also excellent, and the massage effect on the scalp or the pores is also excellent (for example, refer to Japanese Laid-Open Patent Publication No. 2000-60640).

Further, a scalp massage brush has been developed which is used to improve the massage effect of the scalp, and a plurality of protrusions which are erected on the pedestal to comb the hair are formed of a soft material such as an elastomer or a synthetic rubber, and are protruded. A plurality of small projections are provided in the front end portion, so that the small projections are flexibly bent to face the scalp at a plurality of points (for example, refer to Japanese Laid-Open Patent Publication No. 2005-160684).

As such a brush, the applicant of the present invention also proposes a scalp massage brush which uses a soft elastomer resin to protrude protrusions of different shapes on the brush surface of the base, that is, mainly functions to comb the hair. A plurality of protrusions and a plurality of protrusions which mainly exert a massage effect, thereby obtaining an excellent massage effect, and exhibiting an excellent sebum removal function and a pore cleaning function (refer to Japanese Laid-Open Patent Publication No. 2007-282681 (hereinafter referred to as a bulletin) 1)).

The present invention provides a scalp massage brush which protrudes from a brush surface of a base with a beak-like protrusion composed of an elastomer resin, and a plurality of pyramid-shaped protrusions composed of an elastomer resin, the crotch protrusion having a flat shape a plurality of front end protrusions are vertically provided at intervals in the longitudinal direction of the flat cross-sectional shape at a front end portion thereof; and a plurality of the above-mentioned dome-shaped protrusions are spaced apart from each other at a central portion of the brush surface a central protrusion group arranged in an in-line shape, wherein the pyramid-shaped protrusions are respectively disposed on both sides of the central protrusion group, and the pyramid-shaped protrusions have a base portion of a truncated cone shape, and further protrude from a front end of the base portion, and The indicator protrusion of the replacement time of the brush is notified by its disappearance or reduction.

The applicant of the present invention has further intensively studied after the patent application of the above-mentioned publication 1 and found that when the scalp massage brush disclosed in the above-mentioned publication 1 has a protrusion made of an elastomer resin, if the protrusion is placed in a state in which sebum is attached for a long time, The sebum penetrates into the interior of the elastomer, which is then easily worn when the brush is used. In particular, as in the case of the scalp massage brush shown in FIG. 1 and FIG. 2 in the above-mentioned publication 1, when the scalp massager is disposed in the central portion of the brush and can effectively smear the dirt such as sebum clogging in the pores, Sometimes, the brush is pressed against the head and used, or the brush is not cleaned after use, and the wear is continued according to the use situation. Even if the protrusion of other parts is less worn, the hair must be replaced. brush. Moreover, since the replacement time of the brush varies greatly depending on the subjective factors of the user of the brush, the following disadvantages may occur: even if the sebum removal function and the pore cleaning function are fully utilized, the hair is replaced at an early stage. Brushing, or ignoring its functionality, has been greatly reduced and continues to be used.

The present invention relates to a scalp massage brush capable of easily recognizing an appropriate replacement time of a brush.

Hereinafter, the preferred embodiments of the present invention will be described.

The scalp massage brush 10 of the present embodiment is such that, for example, when shampooing or combing the hair, the grip portion 11 is sandwiched between the fingers, and the palm is brought into close contact with the susceptor 12 on the opposite side of the brush surface 13. And holding the brush 10 in such a manner as to cover the upper surface, and the plurality of dome-like protrusions 14 and the front end of the pyramid-shaped protrusion 15 which are erected on the brush surface 13 are attached to the scalp, and the brush 10 is moved in this state. In order to comb the hair, the action of the cleaning agent, the hair care agent, the cosmetic, and the like which are applied to the scalp or the hair as needed can be complemented, and the sebum removal and the pore cleaning can be effectively performed, and an excellent massage effect can be obtained.

Each of the above-mentioned beak-like projections 14 is made of an elastomer resin and has a flat cross-sectional shape, and is provided at a predetermined interval in the longitudinal direction X (see FIG. 2) of the flat cross-sectional shape of each of the distal end portions. Front end projections 14b. Each of the above-described pyramidal projections 15 is made of an elastomer resin and has a pyramidal shape. The shape of the cone is also included in the shape of the small protrusion at the front end of the base of the truncated cone.

The pedestal 12 is made of a plastic material such as polyethylene, polypropylene, or the like, and as shown in FIG. 3, the base 12 includes a base body 17 whose bottom surface is opened in an elliptical shape to form a mounting opening 17a. The curved surface is curved, for example, having a major axis length of about 80 to 100 mm, a short axis length of about 70 to 90 mm, and an elliptical shape in plan view; and a substrate 18 for closing the mounting opening 17a of the base body 17. The way is embedded and fixed.

On the inner side of the base body 17, a mounting recess 17b for mounting the chassis portion 19a of the elastic body molded body 19 described below is provided so that the mounting opening 17a is opened on the bottom surface side, and on the upper surface of the base body 17, The front portion of the base body 17 is provided with a grip portion 11 that protrudes upward in a shape that is curved rearward in a large wave shape.

The substrate 18 has an elliptical shape in plan view substantially conforming to the opening shape of the mounting opening 17a of the base body 17, and is formed in a projecting peripheral end surface 18a and an opening edge portion along the mounting opening 17a. The locking recesses 17c on the inner circumferential surface of the seat body 17 are engaged with each other, thereby being fixed to the base body 17. On the substrate 18, a plurality of elliptical protrusion holes 20 and circular protrusion holes 21 are provided corresponding to the arrangement positions of the following projections 14 and the conical projections 15 (see FIGS. 2 and 4). The lower surface of the substrate 18 serves as a bottom surface of the susceptor 12 to form a brush surface 13, and a plurality of dome-like projections 14 and pyramid-shaped projections 15 respectively protrude from the brush surface 13. Therefore, like the substrate 18, the brush surface 13 also has an elliptical shape in plan view.

Further, the substrate 18 is covered and fitted into the mounting opening 17a of the base body 17 to be fixed. At this time, a plurality of dome-shaped projections 14 and a plurality of pyramid-shaped projections 15 which are integrally formed from the chassis portion 19a of the elastic molded body 19 are integrally formed, and are inserted into the plurality of elliptical projection holes 20 and a plurality of circular projection holes, respectively. Within 21. Further, between the substrate 18 and the support rod 17d (see Fig. 3) which is suspended from the inner top surface portion of the attachment recess 17b of the base body 17, or the peripheral step portion 17e of the attachment recess 17b, elastic body molding is sandwiched therebetween. The chassis portion 19a of the body 19. Thereby, the plurality of beak-like projections 14 and the plurality of conical projections 15 are respectively protruded downward from the lower surface of the substrate 18 constituting the brush surface 13 of the scalp massage brush 10, and the chassis portion 19a is housed and fixed to the mounting recess 17b. In the state, the elastomer molded body 19 is attached to the susceptor 12.

The elastomer molded body 19 is a resin molded article formed using an elastomer resin such as an olefin-based elastomer, a styrene-based elastomer, a polyester-based elastomer, or a polyurethane-based elastomer, and includes: The plate-shaped undercarriage portion 19a having the same elliptical planar shape as the opening 17a is mounted, and a plurality of beak-like projections 14 and a plurality of conical projections 15 projecting integrally from the chassis portion 19a. As described above, the elastic molded body 19 is attached to the base body 17 in a state in which the chassis portion 19a is housed and fixed to the mounting recess 17b, and the beak-like projections 14 and the pyramid-like projections 15 are formed from the substrate at a desired height as described below. The brush surface 13 formed by the 18 is protruded. Here, as the elastomer resin for forming the elastomer molded body 19, for example, hardness (Shore A hardness, rubber hardness meter (GS709N Form A) according to Teclock Co., Ltd.) ASTM D2240A 0-100 is preferably used. (The value measured by Xiao A hardness) is a material of 40 to 80. By using such a material as the elastomer resin for forming the elastomer molded body 19, the weir 14 and the pyramidal projection 15 can be pressed against the scalp without being damaged by the scalp and the painless pressure. Therefore, it is possible to give a moderate stimulation, thereby obtaining an excellent massage effect, and complementing the action of a cleaning agent applied to the scalp or the hair as needed, and effectively performing sebum removal and pore cleaning. Further, when the scalp massage brush 10 is used together with a shampoo or a hair restorer, the elastomer molded body 19 is preferably formed using the olefin-based elastomer or the styrene-based elastomer excellent in chemical resistance. .

Further, in order to improve the clean feeling of the scalp massage brush, it is preferred 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 self-transparent or translucent elastomer, and various additives (for example, abrasion-resistant additives) are added in a small amount. As a degree of transparency, the haze value specified by JIS (Japanese industrial standard) K7136 is preferably 5 to 30%, more preferably 10 to 20%, and particularly preferably 13 to 17%. It improves the cleansing sensation of the scalp massage brush and maintains the moderate durability of the brush. As a specific elastomer molded body, a styrene-based elastomer of Aronkasei Co., Ltd. is commercially available as an elastomer AR (the above-mentioned hardness of 55 to 60).

The cross-sectional shape of the root portion of the brush surface 13 as the beak-like projection 14 is, for example, a flat elliptical shape having a major axis length of about 5 to 20 mm and a minor axis length of about 2 to 15 mm (see Fig. 2), and also 5(a) and 5(b), the beak-like projection 14 includes a beak portion 14a which has a substantially similar cross-sectional shape and has a slightly tapered front end; and three front end projections 14b, etc. The front end of the weir portion 14a further protrudes upward. Further, the beak-like projections 14 are erected such that the height h1 from the front end of the self-brushing surface 13 to the front end projection 14b is, for example, 5 to 25 mm, preferably 10 to 20 mm, and the height h2 of the beak portion 14a is occupied to the front end projection. The height of the height h1 from the front end of 14b is 70 to 95%, and the beak portion 14a becomes the main portion of the condyle 14. Thereby, the function of combing the hair can be effectively exerted, and the force is easily transmitted to the front end portion when pressed against the scalp.

The front end projection 14b provided at the front end portion of the beak-like projection 14 has, for example, a substantially conical shape in which the front end is formed in a convex curved shape, and protrudes from the front end of the beak portion 14a by, for example, 1 to 5 mm, preferably more than 2.5 mm. H3, and in the long-axis direction X of the flat cross-sectional shape of the beak-like projection 14, for example, the root interval s1 is 0 to 5 mm, and the top interval s2 is 1 to 7 mm, preferably 2 to 5 mm. Three of the domes 14 are erected on each other. Further, the ratio (h3/d) of the height h3 of the tip end projection 14b to the thickness (diameter) d of the root portion is preferably 0.4 to 2.5, more preferably 1.0 to 2.0.

By setting the ratio of the height h3 of the front end projection 14b to the thickness d of the root portion in the range of 0.4 to 2.5, when pressed against the scalp, it is easy to comb the hair to reach the scalp or the pores, thereby providing better sebum cleaning. The effect, and moderate stimulation can be used to obtain a more excellent massage effect. Further, in particular, by setting the ratio of the height h3 of the distal end projection 14b to the thickness d of the root portion to be 2.5 or less, the height of the distal end projection 14b is suppressed, and not only the force can be transmitted through the distal end projection 14b, but also the bending is difficult. Or warping, so that the hair is less entangled, and it is easy to straighten the entangled hair. Further, the thickness d of the front end projection 14b means a diameter when the cross-sectional shape of the root portion is circular, and a shape other than a circular shape means twice the secondary radius of the cross-section.

As the pyramid-shaped projection 15, the cross-sectional shape along the root portion of the brush surface 13 is formed into a circular shape having a diameter of, for example, about 4 to 10 mm (refer to FIG. 2), and as shown in FIG. 6, includes: a truncated cone The base portion 15a has a substantially similar cross-sectional shape and has a slightly tapered front end; and a plurality of indicating projections 15b and 15c which protrude upward from the front end of the base portion 15a. The pyramidal projection 15 is erected such that the height h4 of the tip end of the self-brushing surface 13 to the indication projections 15b and 15c is, for example, 5 to 25 mm, preferably 10 to 20 mm, and the height h5 of the base portion 15a of the truncated cone shape is occupied. The brush surface 13 is 90 to 98% of the height h4 of the tips of the projections 15b and 15c, and the base portion 15a is a main portion of the pyramidal projection 15.

In the present embodiment, as the indicating projections, as shown in Figs. 6, 7(a) and 7(b), there are two kinds of tip projections, that is, the first tip end projections 15b and the second front end projections 15c.

Regarding the front end projections 15b and 15c as the indication projections, the projection height h6 (refer to FIG. 6) which protrudes from the front end of the truncated cone-shaped base portion 15a is lower than the height h3 of the front end projection 14b of the above-mentioned projection 14 . Thereby, the front end projection 14b of the beak-like projection 14 is softly deformed to exhibit an excellent sebum removal function and a pore cleaning function, and on the other hand, it is visually easy to discern the disappearance or reduction of the front end projections 15b, 15c of the pyramidal projection 15. . Further, the front end projections 15b and 15c function as an instruction projection for notifying the brush replacement time. Further, the amount of sebum adhered to the front end projections 15b and 15c of the tapered projection 15 can be reduced, and the penetration of sebum into the interior of the elastic body can be suppressed, and the projection can be easily worn after the brush is used later. Phenomenon, and the appropriate replacement time of the brush can be discerned.

With respect to the front end projections 15b and 15c as the indication projections, the projection height h6 (see FIG. 6) is preferably 70% or less of the height h3 (see FIG. 5(a)) of the front end projections 14b of the bell-shaped projections 14, and more preferably The good is 10~50%, especially 15~40%. Further, the height h6 of each of the front end projections 15b, 15c is preferably from 0.3 to 20 mm, more preferably from 0.3 to 10 mm, particularly preferably from 0.3 to 5 mm, particularly preferably from 0.5 to 1.5 mm.

Further, in the present embodiment, the first distal end projection 15b and the second distal end projection 15c have the same projection height h6 from the distal end of the base portion 15a. When there is a difference in height at the front end of the base portion 15a, the height of the highest front end projection is set to the height h6 of the front end projection provided at the front end of the pyramidal projection 15, and the height of the front end projection 14b of the beak projection 14 (The average value when the height of the front end protrusion 14b is different) is compared.

See Figure 7(a) and Figure 7(b). In the present embodiment, the first distal end projection 15b has a hemispherical shape and is disposed at a central portion of the front end of the base portion 15a of the truncated cone shape. On the other hand, the second distal end projection 15c has a substantially hemispherical shape, and more specifically, the base portion is formed in a columnar shape, and the distal end thereof is formed into a hemispherical convex curved surface. Further, the second distal end projections 15c are formed in plural numbers so as to surround the periphery of the first distal end projections 15b. The number of the second distal end projections 15c surrounding the periphery of the first distal end projection 15b can be, for example, about 3 to 10, preferably 4 to 10, more preferably 5 to 8. Preferably, the plurality of second distal end projections 15c are disposed around the first distal end projection 15b at substantially equal intervals. By arranging a plurality of, in particular, three or more second distal end projections 15c to surround the central portion, the distal end projection can be worn regardless of the brush moving direction when the brush is used, so that the front end can be visually recognized easily. The protrusion 15c disappears or decreases.

In the second distal end projection 15c of the present embodiment, the thickness d2 of the root portion is smaller than the thickness d1 of the root portion of the first distal end projection 15b. As the thicknesses d1 and d2 of the front end projections 15b and 15c, when the cross-sectional shape of the root portion is circular, it means the diameter thereof, and when it is a shape other than a circular shape, it means twice the secondary radius of the cross-section.

The ratio of the protrusion height h6 of the first front end projection 15b protruding from the front end of the base portion 15a to the thickness (diameter) d1 of the root portion (h6/d1) is preferably 0.3 to 0.85, more preferably 0.5 to 0.75. Further, the ratio of the projection height h6 of the second distal end projection 15c protruding from the front end of the base portion 15a to the thickness (diameter) d2 of the root portion (h6/d2) is preferably 0.5 to 2.0, more preferably 0.7 to 1.5.

Moreover, it is preferable that the distance S3 (see FIG. 7(b)) between the root portions of the second distal end projections 15c adjacent to each other is 0.3 to 2 mm and the distance S4 between the top ends (see FIG. 7 (see FIG. 7). b)) is placed around the first front end projection 15b in a manner of 2.5 to 4 mm.

Further, in the present embodiment, the amount of bending measured by the force applied to the front end projection 14b of the beak-like projection 14 along the longitudinal direction X of the flat cross-sectional shape of the beak-like projection 14 is larger than that from the same direction. The amount of bending measured by the same force is applied to the projections 15b and 15c. Thereby, the front end projection 14b of the beak-like projection 14 is softly deformed, thereby exerting an excellent sebum removal function and a pore cleaning function. On the other hand, the pyramidal projection 15 becomes a relatively stable erect state, and the pyramidal projection 15 The massage effect is improved, and the front end projections 15b, 15c disappear or the speed of the reduction is relatively fast, and the function as the indication protrusion is also improved. Further, the amount of sebum adhered to the front end projections 15b and 15c of the tapered projection 15 can be reduced, and the penetration of sebum into the interior of the elastic body can be suppressed, and the projection can be easily worn after the brush is used later. Phenomenon, and the appropriate replacement time of the brush can be recognized.

When the amount of the bending is measured, a force of 200 gf parallel to the brush surface is applied to the center portion of the tip end projection 14b or the instructing projections 15b and 15c in the height direction while the brush surface is horizontally fixed, and the force is measured. The distance the point moves. The larger the moving distance, the larger the amount of bending. Further, in the measurement, in order to prevent the beak portion 14a of the beak 14 and the truncated cone base portion 15a of the pyramidal projection 15 from being bent, it is preferable to fix the portion by a plate or the like.

As shown in Fig. 2, in the present embodiment, on the substantially entire surface of the brush surface 13 of the susceptor 12, a dome-like projection 14 is provided at 16 places, and a pyramid-shaped projection 15 is provided at eight places. The configuration is distributed substantially evenly.

In the present embodiment, a central projection group 14R is provided in a central portion of the brush surface 13 so as to be spaced apart from each other by four dome-shaped projections 14, and the center is sandwiched between the central projection groups 14R. The pyramid-shaped projections 15 and 15 are disposed in the manner of the projection group 14R, respectively.

Further, in the present embodiment, the bell-shaped projections 14 are provided at the outer peripheral portion of the peripheral edge of the brush surface 13 of the susceptor 12 at the periphery. The dome-like projections 14 constituting the center projection group 14R are transversely cut to the central portion of the inner region 22 surrounded by the dome-like projections 14 of the outer peripheral portion, and are arranged in a line in a row. The pyramid-like projections 15 are located on both sides of the central projection group 14R and are erected in the inner region 22 surrounded by the dome-like projections 14 of the outer peripheral portion.

In the present embodiment, the "central portion of the brush surface 13" means "on the long axis of the brush surface 13 having an elliptical shape in plan view", and the above-mentioned "both sides of the central projection group 14R" means "in view of At the time of the elliptical shape, the brush surface 13 has both sides on the center of the central projection group 14R in the short axis direction.

Further, in the present embodiment, the sixteen-shaped projections 14 are erected in the same direction in which the long-axis direction X of the flat cross-sectional shape is parallel to the short-axis direction of the elliptical brush surface 13. By erecting the long-axis direction X of the flat cross-sectional shape of the beak 14 in the same direction, adhesion or entanglement of the hair can be effectively prevented, and even if hair is attached or entangled, it can be easily removed, and When the scalp massage brush 10 moves in the direction of the minor axis of the brush surface 13, the function of scratching the scalp or hair is improved.

Further, the height h2 of the beak portion 14a of the beak-like projection 14 is set lower than the height h5 of the truncated cone-shaped base portion 15a of the conical projection 15, and the height h3 of the front end projection 14b of the beak-like projection 14 is set to be high. In the height h6 of the first and second distal end projections of the pyramidal projection 15, when the scalp massage brush 10 is used, the front end projection 14b of the condyle 14 pressed against the scalp can be bent along the scalp. It can effectively scratch dirt such as sebum blocked in the pores. On the other hand, the indicator projections 15b and 15c of the pyramidal projection 15 can be pressed against the scalp with almost no bending, so that the amount of sebum adhering to the distal end projections 15b and 15c can be reduced, thereby suppressing sebum Penetration into the interior of the elastomer results in a situation in which the protrusion is easily worn after the brush is used, and the appropriate replacement time of the brush can be recognized.

Further, in the brush of the present invention, the central portion of the brush surface has a central projection group 14R which is formed by a plurality of meandering projections 14 spaced apart from each other, and a cone is disposed on both sides of the central projection group. Since the hair piece 15 is used, the brush can exert the following effects. In other words, the plurality of the bell-shaped projections 14 are provided in the center portion of the brush surface in a straight line to form the central projection group 14R. Therefore, the scalp can be more strongly contacted, and the sebum removal function and the pore cleaning function can be exhibited. The reason is that the outline shape of the head is not flat. On the other hand, since the pyramid-shaped projections 15 are disposed on both sides of the central projection group 14R, the indication projections 15b and 15c of the pyramidal projections 15 can be pressed against the scalp with almost no bending, so that adhesion can be performed. The amount of sebum adhering to the distal end projections 15b and 15c is small, and it is possible to suppress the sebum from penetrating into the interior of the elastic body, thereby causing the projection to be easily worn when the brush is used later, and the appropriate replacement time of the brush can be recognized.

Further, in the present embodiment, as shown in Figs. 3 and 4, the front end of the front end projection 14b of the plurality of beak-like projections 14 and the front end of the front end of the indication projections 15b and 15c of the plurality of conical projections 15 are connected. S is a concave curved surface that is recessed inward along the contour of the head. If the front end connecting surface S is a flat surface, depending on the state of use of the scalp massage brush, the amount of wear of the central projection group 14R may be relatively large. On the other hand, by forming the front end connecting surface S as a concave curved surface, it is possible to suppress unevenness in the wear degree of the plurality of beak-like projections 14 and the plurality of tapered projections 15 at the front end portions, so that it can be used for a long time. Maintains excellent sebum removal and pore cleansing.

In view of the fact that the degree of wear of the front end portions of the plurality of conical projections 14 and the plurality of conical projections 15 is uneven, and the sebum removal function and the pore cleaning function can be maintained for a long period of time, The radius of curvature of the concave curved surface is preferably 150 to 400 mm in the longitudinal direction of the brush surface, and preferably 180 to 350 mm in the short 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 the fingers, and the palm is brought into close contact with the upper surface of the susceptor 12 opposite to the brush surface 13 to cover the upper surface. The brush 10 is held by the brush, and the plurality of braided protrusions 14 and the front end of the pyramidal protrusion 15 which are erected on the brush surface 13 are pressed against the scalp, and the brush 10 is moved to comb the hair in this state. By applying a cleaning agent, a hair care agent, a cosmetic, or the like to the scalp or hair as needed, the hair is shampooed or combed. Here, the side surface of the grip portion 11 has a shape recessed in a concave shape along the side surface of the finger, and the brush 10 is attached to the hand and held in a stable state, so that, for example, one side can be easily and smoothly performed. The scalp massage brush 10 is moved in the direction of the short axis of the brush surface 13 to open the hair.

Further, according to the scalp massage brush 10 of the present embodiment, protrusions of different shapes are erected on the brush surface 13 of the susceptor 12 by using a soft elastomer resin, that is, a plurality of dome-like projections 14 and a plurality of pyramid-like projections 15 The plurality of bell-shaped protrusions 14 mainly function to comb the hair, and the plurality of pyramid-shaped protrusions 15 mainly exert a massage effect, thereby obtaining an excellent massage effect, and exhibiting an excellent sebum removal function and pore cleaning function. . Further, according to the present embodiment, a plurality of dome-shaped members made of an elastomer resin are provided on the brush surface 13 of the susceptor 12 and have a flat cross-sectional shape and a plurality of distal end projections 14b are provided at the distal end portion. The protrusions 14 and the plurality of pyramid-shaped protrusions 15 composed of an elastomer resin, in particular, the pyramidal protrusions 15 stimulate the action of the scalp and the vicinity of the root portion with an appropriate pressure, thereby obtaining an excellent massage effect. Further, the action of the hair is combed by the beak-like projections 14 provided with the distal end projections 14b, and the front end projections 14b are pressed against the scalp in a state in which the front end projections 14b are not subjected to the pain. Effectively achieve sebum removal and pore cleansing.

Further, according to the scalp massage brush 10 of the present embodiment, since the front end portions of the pyramid-shaped projections 15 have the indication projections 15b and 15c for informing the replacement time of the brush, the disappearance or reduction of the projections 15b and 15c can be instructed as the judgment basis. By replacing it, the following problems can be eliminated or reduced: even if the sebum removal function and the pore cleaning function are fully utilized, the brush is replaced at an early stage, or the function of ignoring it has been greatly reduced and continues to be used.

In order to facilitate the user or the like to replace the brush with the disappearance or reduction of the indication protrusions 15b, 15c as a basis for judging, it is preferable to store the brush in the front end portion of the protrusion in which the protrusion of the brush surface 13 is described. It is sold in a package which disappears or reduces the description as a basis for determination, or the brush is stored in a package to which the description of the above description is attached, and the like.

As the package, a scalp massage brush can be used, and it is not particularly limited, and a bag made of a resin film, a box made of paper or synthetic resin, a composite of a synthetic resin case and paper, or the like can be used. The description of the above description is not particularly limited. Further, the expression method and the like described are not particularly limited, and can be expressed by only a character, and can be expressed by a combination of a figure (illustration or the like) or a combination of a photo and a character, or can be expressed only by a figure or a photograph. The description method is also not particularly limited, and a previously known method such as direct printing onto a packaging material or a paper or film print may be attached.

As a character that causes the disappearance or reduction of the front end portion of the protrusion protruding on the brush surface as a basis for judging, it is possible to distinguish the beak-like protrusion from the conical protrusion, such as "please a small protrusion at the front end portion of the pyramidal projection" Words such as "replace when disappearing" or "replace when small protrusions at the front end of the pyramidal protrusion begin to decrease", but if you consider the attention of the general consumer, you can also distinguish the dome and the cone. The shape of the protrusion is "recommended to replace the new cleaning brush when the end of the brush starts to decrease" or "replace when the small protrusion at the front end of the brush disappears".

The instructions attached to the package may be enclosed inside the package together, or may be attached to the package by rope or rubber or the like.

Fig. 8 is a view showing a bubble wrapper (package) 30 in which a brush 10 is housed, comprising: a transparent plastic portion 31 having a portion 31a protruding forward; and a plate-like portion 32 of paper which is engaged with The back side of the plastic portion 31 is integrated with it. "Description of the disappearance or reduction of the front end portion of the protrusion protruding on the brush surface as a basis for judging", for example, the portion shown by the symbols 33 to 37 in Fig. 8 which can be attached to the bubble wrapper 30 . Reference numeral 37 denotes the back side of the bubble wrap.

Furthermore, the present invention is not limited to the above embodiment, and various modifications can be made.

For example, it is not necessary to erect a beak-like protrusion along the outer peripheral portion of the peripheral surface of the brush surface, and to establish a pyramid-shaped protrusion on the inner side of the inner surface or the central portion of the inner side portion to provide a row of the protuberances. A plurality of dome-shaped protrusions may be mixed with a plurality of pyramidal protrusions and randomly erected on the entire brush surface. Further, the dome-like projections may have other flat cross-sectional shapes such as an oblong shape or a rectangular shape in addition to the elliptical cross-sectional shape, and the pyramid-shaped projections may have a pyramid shape or the like in addition to a substantially conical shape. Further, two or more front end projections may be provided in the conical projections, and the front end projections may have other shapes than the conical shape.

The number of the dome-shaped projections 14 constituting the central protrusion group 14R may be three or more. Further, the central protrusion group 14R may be formed by arranging the ridge protrusions 14 in the longitudinal direction of the elliptical brush surface 13, or may be arranged such that the ridge protrusions 14 are arranged in the short axis direction. .

Further, as the indicating projection, as shown in Fig. 9, a front end projection 15g may be provided at the front end of the truncated cone-shaped base portion 15a, and the front end projection 15g includes a cylindrical portion 15d having a diameter smaller than the diameter of the front end portion 15a' of the base portion 15a. And a small conical portion 15e having a diameter larger than the diameter of the cylindrical portion 15d and smaller than the diameter of the front end portion 15a' of the base portion 15a. The front end projection 15g shown in Fig. 9 is provided in a state in which the cylindrical portion 15d is connected to the front end of the base portion 15a. When the portion of the cylindrical portion 15d in the front end projection 15g as shown in Fig. 9 is broken and the small conical portion 15e is removed from the base portion 15a (corresponding to the disappearance of the front end portion), it is preferable to use this as a standard. Replace the brush.

Further, similarly to the front end projections 15b and 15c of the pyramidal projection 15 of Fig. 7(a), the front end projection 15g may have an indication projection for notifying the replacement time of the brush as a basis for judging the disappearance or reduction of wear. Features.

Further, in the above-described scalp massage brush 10, the beak portion 14a and the front end projection 14b of the beak-like projection 14 are integrally formed of the same material, and the base portion 15a of the pyramidal projection 15 and the first and second front end projections 15b, 15c are integrally formed. Although it is integrally formed from the same material, the front end projection 14b and the first and second front end projections 15b and 15c which are separately manufactured may be integrated with the beak portion 14a and the base portion 15a by a method such as thermal fusion.

In the package in which the description of the disappearance or reduction of the front end portion of the projection protruding on the brush surface is performed as a basis for judging, the description having the description may be further included.

According to the scalp massage brush of the present invention, an excellent massage effect can be obtained and an excellent sebum removal function and a pore cleansing function can be exerted, and the appropriate replacement time of the brush can be easily recognized. That is, sebum removal and pore cleansing are effectively performed by the presence of the central protrusion group, and on the other hand, the amount of sebum adhering to the indicator protrusion of the pyramidal protrusion is small, thereby suppressing sebum penetration. The inside of the elastomer causes the protrusion to be easily worn out after the brush is used, and the appropriate replacement time of the brush can be recognized.
