Description

  The present invention can effectively remove not only the surface of the scalp but also the dirt inside the pores by using the hair whose tip is thinner than the scalp pores, and has an excellent massage effect. Regarding brushes.

  Conventionally, various brushes for cleaning the scalp and hair have been known. For example, a brush having a spherical body at the tip of a bristle (hair) (see Patent Document 1) or a brush having a spherical body. A combination of hair and hair having no spherical body (see Patent Document 2), a hair having a substantially conical hair whose outer peripheral surface in the length direction is a concave curved surface (see Patent Document 3), Proposals have been made of small protrusions (see Patent Document 4) that flexibly bend when the hair tips touch the scalp (see Patent Document 5), and the like.

  Conventionally, a scalp massage brush in which a plurality of protrusions made of an elastomer resin are implanted on the brush surface has been proposed as a brush for providing a massage effect as well as a cleaning effect on the scalp (for example, Patent Documents). 6). However, the brush described in Patent Document 6 has a problem that the scale of the protrusions is larger than the size of the pores, so that removal of dirt inside the pores is insufficient.

  In order to solve the problem of cleaning power inside the pores as described above, dirt inside the pores can be effectively removed by using tapered hair whose tip portion has a smaller diameter than the scalp pores. A scalp brush has been proposed (see, for example, Patent Document 7). However, the scalp brush described in Patent Document 7 has a problem that the massage effect on the scalp is low, although it has an excellent cleaning effect inside the pores due to the use of fine hair.

In addition, in order to clean the scalp pores and to give a massage effect to the scalp, a brush is proposed in which a bundle of small-sized bristles and a large-sized bristles are arranged at regular intervals in a predetermined arrangement. (For example, see Patent Documents 8 and 9). According to the brushes described in Patent Documents 8 and 9, pores can be washed with a small-diameter bristle and a massage effect can be imparted to the scalp with a large-diameter bristle.
However, in the configurations described in Patent Documents 8 and 9, since bundles of small-sized bristles and large-sized bristles are arranged adjacent to each other, it is difficult to obtain both a cleaning effect and a massage effect at the same time. There was a problem that there was.
Japanese Utility Model Publication No. 54-87272 Japanese Utility Model Publication No. 54-16673 Japanese Utility Model Publication No. 3-102928 JP 2005-160684 A Utility Model Registration No. 3113002 JP 2006-136360 A JP 2007-282682 A Japanese Patent Laid-Open No. 11-70019 Japanese Patent No. 3076313

On the other hand, in order to realize a brush capable of giving a massage effect to the scalp, a hair bundle made of tapered hair whose tip is thinner than the scalp pore is used, and on the brush surface, the hair bundle It has also been proposed to pattern the arrangement in a predetermined arrangement.
However, when a brush having such a arrangement of hair bundles is arranged in a predetermined manner, for example, when a user with long hair uses it for washing the hair, the hair is easily entangled with the hair constituting the hair bundle. It may be difficult for the tip to reach the scalp reliably. In such a case, it is difficult to obtain a high massage effect on the scalp, and it is difficult for the user to feel the reach of the hair to the scalp, so the massage effect feeling due to the use of the brush becomes even lower. There was a problem.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a scalp brush capable of simultaneously satisfying both the scalp massage effect and the pore cleaning effect.

  As a result of intensive studies by the present inventors in order to solve the above problem, the arrangement of the hair bundle in which a plurality of hairs are bundled and the cone-shaped protrusions made of an elastic material is appropriate on the brush surface of the scalp brush. As a result, it was found that both the massage effect of the scalp and the cleaning effect inside the pores can be satisfied simultaneously, and the present invention has been completed.

  That is, according to the present invention, at least one end side is tapered, and a hair bundle formed by bundling a plurality of bristles whose diameter is smaller than that of the scalp pores, and a tip made of an elastic material is chamfered.

On the brush surface, the bristles are arranged on the outer peripheral portion along the periphery of the brush surface, and the cone-shaped projections are arranged on the inner side of the outer peripheral portion on which the bristles are implanted. Scalp brush characterized by being made To provide.

Further, the scalp brush of the present invention is configured such that when the bristles have 3 to 9 flocked holes in which the bristles are planted on the brush surface, one unit is included in one unit. The distance between the centers of the flock holes at the location is in the range of 2 mm or more and less than 15 mm, and the distance from the center point of any one unit to the center point of the nearest unit is 10 mm or more and less than 25 mm It can be set as the structure formed by flocking to the flocking hole.
In the scalp brush of the present invention, on the brush surface, the length of the hair for forming the hair bundle from the brush surface is larger than the length of the cone-shaped protrusion from the brush surface. It can be set as the structure made into the long dimension in the range of 1 mm or more and 5 mm or less.
In the scalp brush according to the present invention, each of the cone-shaped protrusions is provided on the brush surface with an interval in the range of 5 mm to 30 mm between the roots of adjacent cone-shaped protrusions. It can be configured to be attached to the hole.
Further, in the scalp brush of the present invention, each of the cone-shaped protrusions is arranged in any of a circular shape, a horizontal stripe shape, a checkered shape, a cross shape, or a radial shape on the brush surface, and the protrusion mounting holes It can be set as the structure attached to.

Moreover, the scalp brush of this invention can be set as the structure by which the area of the outer peripheral part in which the said flock hole is provided was made into the range of 40% or more and 60% or less by the area ratio with respect to the said brush surface.

The scalp brush 1 of the present embodiment has a hair bundle 3 formed by bundling a plurality of hairs 31 having a tapered shape at least on one end side and a tip 31a having a diameter smaller than that of the scalp pores, and an elastic material. A plurality of cone-shaped projections 5 having chamfered tip portions 5a, and a plurality of flocking holes 22 for flocking the hair bundle 3, and a plurality of projection mounting holes 23 for attaching the cone-shaped projections. The hair bundle 3 is implanted in each of the flocked holes 22 at a density such that the inside of the flocked hole 22 is not observed from the outside, and each of the protrusion mounting holes 23 has a cone. The bristle protrusion 5 is attached, and on the brush surface 21, the hair bundle 3 is arranged on the outer peripheral portion 21 b along the peripheral edge 21 a of the brush surface 21, and the cone-like protrusion 5 is implanted in the hair bundle 3. Arranged on the inner side of the outer peripheral portion 21b ( Referring to the inner peripheral portion of the code 21c in 2), it is schematically configured.
Further, the scalp brush 1 of the present embodiment is further provided with a housing 4 formed in a hollow shape (see the hollow portion 4a in FIG. 1A) having an opening 41 in the example shown in FIG. At the same time, the base 2 is integrally attached to the opening 41 of the housing 4.

The base 2 is provided with a plurality of hair bundles 3 and cone-shaped protrusions 5 made of hair 31, and a plurality of flocking holes 22 for flocking the hair bundle 3 are formed on the brush surface 21. A plurality of projection attachment holes 23 to which the cone-like projections 5 are attached are formed. Further, the base 2 in the illustrated example is formed in a flat plate shape that is substantially elliptical in plan view.
As a material of the base 2, a general hard resin material such as polypropylene can be used without any limitation.

The size and shape of the flocking hole 22 are not particularly limited, and may be a size necessary for flocking about 10 to 30 hairs per hole, for example. Further, the shape of the flocking hole 22 can be generally circular. However, for example, as shown in Japanese Patent Application Laid-Open No. 2000-50955, the purpose is to improve the quality of the brush and the manufacturing efficiency. In addition to a perfect circle shape, it may be formed in a non-circular shape.
Moreover, the flock holes 22 need to form an arrangement pattern on the brush surface 21 according to the flock pattern of the hair bundle 3, and in the example shown in FIG. 2, three flock holes 22 combined at a predetermined interval are provided. A total of 6 holes are arranged in parallel to form one unit, and each unit is appropriately arranged in the region of the outer peripheral portion 21b on the brush surface 21 according to an arrangement pattern to be described in detail later.

The size and shape of the protrusion mounting hole 23 are not particularly limited, and may be determined as appropriate according to the size and shape of the cone-shaped protrusion to be attached. You may form in.
Further, the protrusion mounting holes 23 need to form an arrangement pattern on the brush surface 21 according to the mounting pattern of the cone-shaped protrusions 5 to be described in detail later. In the example shown in FIG. A total of ten pieces are arranged on the inner peripheral portion 21c on the brush surface 21 inside the outer peripheral portion 21b. In the illustrated example, in the inner peripheral portion 21 c of the brush surface 21, eight projection mounting holes 23 are arranged in an elliptical shape, and two projection mounting holes 23 are arranged inside the elliptical shape.

  In addition, although the fitting claw 24 for attaching to the housing | casing 4 mentioned later is arrange | positioned at the base 2 of the example of illustration so that it may face on the meridian of the short side of the base 2 made into the ellipse shape. The means for attaching the base 2 to the housing 4 is not limited to this. For example, the fitting claws may be arranged on the base at a position different from the illustrated example, or the base may be attached to the housing by screwing or the like.

The hair bundle 3 is formed by bundling a plurality of hairs 31.
As shown in FIG. 3, the hair 31 is tapered at least at one end side, and in the illustrated example, the tip portions 31a at both ends are formed in a tapered shape. The tip 31a has a diameter d at least near the end surface 31b that is smaller than the pores of the scalp.

As shown in the example, when each of the small-sized bristle forming the hair 31 is configured in a tapered shape, the tip of the tip 31a (see the end face 31b) hits the hair on the scalp. Even if the force is weak, the tip 31a is easily bent, so that the hair tips can reach the pores of the scalp so as to pass between the hairs. Moreover, by comprising the hair | bristle bundle 3 using such a taper hair 31, the hair front-end | tip penetrates into the pore of a scalp reliably, and the dirt inside a pore can be removed effectively. Further, at this time, the tips of the plurality of hair bundles 3 (hair 31) constitute a substantially single plane, so that it is possible to prevent only specific hair from hitting the scalp and damaging the scalp. .
In addition, since the hair with a tapered shape has a low strength at the tip, it is difficult to clean the pores because the tip of the hair is bent when the scalp is cleaned or massaged with an extremely strong force. It may become. For this reason, as a load which a user applies to a brush at the time of scalp washing | cleaning, it is preferable to set it as about 300-1000g in general.

  The hair 31 preferably has a diameter d in the range of 5 μm to 50 μm at a position of 0.1 mm from the end surface 31 b of the tip part 31 a described above. By setting the diameter d in the vicinity of the end face 31b of the distal end portion 31a within this range, the hair 31 can efficiently enter the pores of the hair and can be effectively washed.

  Here, in the scalp brush, it is considered that scalp pores can be washed if only a small diameter hair is densely implanted without using a large diameter hair. However, although the diameter of human hair varies depending on race, sex, age, presence / absence of comb hair, etc., it is about 40 to 100 μm in general Japanese, and about 70 μm on average, so several hairs grow. The size of one pore is considered to be equal to or larger than the diameter of the hair, and is considered to be an average of 70 μm or more. However, in the case where the brush is constructed by closely planting the hair for narrow diameter, which has a diameter smaller than the size of the pore as described above, and which can be inserted into the pore, with respect to the brush surface, If the hair ends of the scalp are pressed against the hair root of the scalp at the time of shampooing, etc., a large number of hairs obstruct the progression of hair for small diameters. It is easy to become. For this reason, since the hair for thin diameters bends easily and the number of the hair for fine diameters which can reach a pore decreases, it is difficult to obtain the target pore cleaning effect. On the other hand, when the hair is planted in a rough state with respect to the brush surface, a feeling of reaching the scalp at the tip of the hair is obtained, but stimulation to the scalp is excessive and a good feeling of use cannot be obtained. There is a problem.

In the scalp brush 1 of this embodiment, in order to remove dirt such as lipids in the pores, the hair bundle formed by using the brush hair whose tip 31a is thinner than the diameter of the pore and bundling the hair 31 3 is arranged on the outer peripheral portion 21b on the brush surface 21, the hair 31 (hair bundle 3) can easily reach the pores of the scalp without hindering movement of the hair, and an excellent cleaning effect is obtained. . Further, since the hair that has come off from the scalp is less likely to be entangled with the hair 31 and can be easily released even if it is entangled, excellent maintainability can be obtained.
Furthermore, in the scalp brush 1 of the present embodiment, the cone-shaped protrusions 5, which will be described in detail later, are appropriately spaced from the inside of the outer peripheral portion 21 b on the brush surface 21, that is, the inner peripheral portion 21 c shown in FIG. 2. By providing and arranging, the user can obtain an appropriate massage feeling without the hair getting entangled with the cone-shaped projections 5.

The hair length of the hair 31 for forming the hair bundle 3 is preferably in the range of 5 to 30 mm.
If the hair length is shorter than 5 mm, the hair may become an obstacle and the hair (hair bundle) may not reach the scalp pores. Moreover, when the hair length of the hair 31 is longer than 30 mm, the hair becomes easy to bend, and the tip portion hardly reaches the scalp and the pores.
In addition, although some dispersion | variation may arise in the hair length of the planted hair 31 (hair bundle 3), about 90% or more of all the planted hair 31 planted has said 5-30 mm hair length. It is preferable in terms of quality to be in the range of 10 and more preferably in the range of 10 to 20 mm.
Although the details will be described later, the length of the hair 31 constituting the hair bundle 3 is such that the length H1 from the brush surface 21 shown in FIG. 4 is the length from the brush surface 21 of the cone-shaped protrusion 5 described later. It is preferable from H2 (refer FIG. 6) that it is comprised so that it may become a dimension long in the range of 1 mm or more and 5 mm or less from the point which both the washing | cleaning effect and the massage effect by the scalp brush are improved.

It is preferable that the number of flocked hairs per hole of the flocked hole 22 is a density in a state where the inside of the flocked hole 22 cannot be observed from the outside. Specifically, the number of flocked hairs 31 per hole is 10 It is preferable that it is -30. If the number of flocks of the hair 31 is so small that the inside of the flock hole 32 can be observed from the outside, the hair that has slipped out of the hair bundle 3 is likely to get entangled, and it is difficult to remove the hair. Moreover, since the cleaning agent, rinse agent, etc. which are used at the time of shampooing enter the flock holes 22 and become clogged easily, it is not preferable in terms of hygiene of the scalp brush.
On the other hand, in the scalp brush according to the present invention in which the number of hairs in such a state that the inside of the flocked hole 22 cannot be observed from the outside is implanted, the hair that has fallen into the hair bundle 3 does not get entangled, Further, since there is no observable gap inside the flocking hole 22, it is possible to prevent the cleaning agent from entering and clogging.

  In addition, when there are few hairs of the hair 31 (hair bundle 3) with respect to the cross-sectional area of the hair hole 22, a slight clearance gap will be produced between the hairs 31 and there are individual differences depending on the user of the scalp brush. There is a possibility that the hair having a thickness of 70 μm is sandwiched in a slight gap between the hairs 31 and becomes extremely difficult to remove.

Below, the reference example of the flocking density of the hair 31 with respect to the flocking hole 22 is demonstrated.
For example, when the hair 31 having a diameter of 190 μm at the center of the thin bristle is implanted into the hair hole 22 having a diameter of 1.5 mm, the 21 hairs 31 are represented by a flat wire having a thickness of 0.25 mm. When the hair is fixed at the center of the hair 31 and planted, the density in a state where the inside of the planted hole 22 cannot be observed from the outside can be obtained. When the state in the flocked hole 22 is examined in terms of the cross-sectional area, the cross-sectional area occupied by the hair 31 with respect to the cross-sectional area of the flocked hole 22 = 0.75 × 0.75 × 3.14 = 1.77 mm ^2. Is 0.095 × 0.095 × 3.14 × 21 × 2 = 1.19 mm ² , and 67% of the cross-sectional area of the flocked hole 22 is occupied by the hair 31.
In addition, as a result of intensive experiments by the present inventors, when the number of flocks of the hair 31 is 13, the ratio of the cross-sectional area of the bristles 31 to the cross-sectional area of the flock holes 22 is 42%. It has been found that a ratio of 42% is a boundary between a state where the inside of the flocked hole 22 is not observed from the outside and a state where it can be observed. When the ratio of the cross-sectional area of the hair 31 to the cross-sectional area of the flocked hole 22 is less than 42%, which is the boundary, the inside of the flocked hole 22 becomes observable from the outside. Hair having a diameter of about 70 μm is easily entangled with the hair 31.

When considering from the viewpoint of easy entanglement of the hair, if the ratio of the cross-sectional area of the hair 31 to the cross-sectional area of the flocked hole 22 is less than 42%, which is the above boundary, the hair is easily entangled with the hair 31, The ratio is preferably 42% or more and 85% or less. When the proportion of the hair 21 in the flocked hole 22 exceeds 85%, the base 2 is easily broken starting from the flocked hole 22 and the planted hair 31 may be opened, which is not preferable.
In addition, if the number of flocks to the flocked hole 22 is less than 10, the scalp pore cleaning effect is reduced, and if the number of flocked is greater than 50, it is necessary to form a large diameter flocked hole in the base 2. In the flocking hole 22, a cleaning agent or a rinse agent used at the time of shampooing easily enters and becomes clogged, which is not preferable in terms of hygiene of the scalp brush.
In addition, although the number of flocks may vary, the number of flocks of the bristles 31 ranges from 10 to 30 in approximately 90% or more of the flock holes 22 in which the bristles 31 (hair bundles 3) are flocked. It is preferable to be within, and it is more preferable that it is the range of 10-25 from quality.
Yes.

The material of the narrow bristle constituting the hair 31 used in the present embodiment is not particularly limited, but polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polytrimethylene terephthalate (which is a general resin material) PTT), nylon, polyester or the like is preferably used. In addition, for example, as described in JP-A-11-253236, for the purpose of improving aesthetics, a material mainly composed of a synthetic resin is mixed with other components, or an antibacterial agent is added for the purpose of improving durability. It is also possible to use what has been done.
When a hard material such as a metal is used as the material for the hair 31, the strength can be ensured even if the bristle diameter is small, so that not only the tapered narrow bristle as shown in FIG. 3 or FIG. 4 is used. It is also possible to use a straight hair. However, when such a straight-haired metal bristle is used, it is not preferable for safety because the cut surface of the defect becomes sharp when the hair is broken when the brush is used, and the scalp is damaged during massage. .

  In addition, it does not restrict | limit especially as a method of processing the thin diameter bristle used for the hair 31 in a taper shape as shown in FIG. For example, a straight hair-shaped bristle may be used, and the tip may be processed into a tapered shape by dissolving the resin by a conventionally known chemical method using a chemical or the like. It is also possible to process into a taper shape by grinding by machining.

  Moreover, as a method for flocking the bristles 3 formed by bundling a plurality of bristles 31 into the flock holes 22 of the base 2, for example, a flocking device generally used for toothbrush production or the like is diverted. It can be used without limitation, and the form of such a flocking device is not limited at all. As such a flocking device, for example, a manufacturing device described in JP 2000-93233 A or the like can be used.

The base 2 to which the hair bundle 3 (hair 31) and the cone-shaped protrusion 5 described later are attached is usually attached with a gripping member such as a handle and is packaged to be a brush product. In the embodiment, the scalp brush 1 is formed by attaching the base 2 to a case 4 described later.
For example, as shown in Japanese Patent Application Laid-Open No. 2001-46149 and the like, for the purpose of improving the quality of the brush (hair bundle 3) after flocking, the base 2 after flocking 3 which is an intermediate product. On the other hand, it is possible to apply a method for performing some kind of treatment, such as heat treatment by cooling or heating, as long as the effects of the present invention are not impaired.

The cone-shaped projection 5 is a projection member that is attached to the brush surface 21 of the base 2 together with the hair bundle 3 (hair bundle 31), and the projection attachment hole 23 formed in the inner peripheral portion 21c of the brush surface 21 described above. Can be attached by means such as fitting. Further, the cone-shaped protrusion 5 may be configured such that, for example, a substrate is further provided on the back side of the base, the cone-shaped protrusion 5 is attached to the substrate, and the through-hole provided in the base is inserted. .
In the example shown in FIGS. 5 and 6, the cone-shaped protrusion 5 is formed in a substantially conical shape whose diameter decreases from the base portion 5 b toward the tip portion 5 a, and the tip portion 5 a is chamfered in a curved shape. However, the present invention is not limited to this. For example, it is possible to adopt a configuration in which one or more circular protrusions are further provided at the tip of the cone-shaped protrusion.

  In addition, the plurality of cone-shaped protrusions 5 are arranged in the same arrangement pattern as the protrusion mounting holes 23 on the inner peripheral portion 21c on the brush surface 21 by being attached to the protrusion mounting holes 23 described above. Then, a total of ten cone-shaped projections 5 are provided. In the illustrated example, in the inner peripheral portion 21c of the brush surface 21, eight cone-shaped projections 5 are arranged in an elliptical shape, and two cone-shaped projections 5 are arranged inside the elliptical shape. Yes.

The diameter of the portion of the base portion 5b where the conical protrusion 5 is attached to the base 2 is preferably in the range of 5 to 9 mm, for example, from the viewpoint of ensuring strength.
Moreover, it is preferable that the diameter in a 0.1-mm part from the front-end | tip is the range of 0.4-1 mm. If the diameter is 0.4 mm, the intended massage effect cannot be sufficiently obtained, and if it is larger than 1 mm, the scalp cleaning feeling is lowered, which is not preferable.

  Moreover, it is preferable to make the length of the cone-shaped protrusion 5, ie, the length H2 from the brush surface 21 of the base 2, into the range of 5-30 mm. If the length H2 of the cone-shaped projection is shorter than 5 mm, the hair may become an obstacle and the tip of the projection may not reach the scalp pore. If the length H2 of the cone-shaped projection is longer than 30 mm, the cone-shaped projection is likely to bend and the tip of the projection is difficult to reach the scalp background or pores. In addition, as with the hair 31 (hair bundle 3), there may be some variation in the length of the cone-shaped projections 5, but all the cone-shaped projections 5 attached to the brush surface 21 of the base 2 are used. Of these, approximately 90% or more is preferably in the range of the length of 5 to 30 mm, and more preferably in the range of 10 to 20 mm.

Further, the length of the cone-shaped projection 5 is such that the length H2 from the brush surface 21 shown in FIG. 6 is the length H1 from the brush surface 21 of the hair 31 forming the hair bundle 3 (see FIG. 4). In comparison, it is preferable that the length is shorter in the range of 1 mm or more and 5 mm or less, that is, the length (length) of the hair 31 is longer than the length of the cone-shaped protrusion 5 in the above range.
As described above, the length of the hair 31 forming the hair bundle 3 on the brush surface 21 is configured to be shorter than the length of the cone-shaped projection 5 in the above range, so that the hair 31 made of a small-diameter bristle can be efficiently used. The scalp can be surely reached and the cone-shaped projections 5 made of an elastic material can surely reach the scalp and have a massage effect. Thereby, it is possible to enhance both the scalp pore cleaning effect by the hair 31 and the scalp massage effect by the conical projections 5.
When the difference between the length H1 of the bristle 31 and the length H2 of the cone-shaped protrusion 5 from the brush surface 21 of the base 2 is less than 1 mm, the tip of the bristle 31 (hair bundle 3) and the cone shape Since the tip of the protrusion 5 tends to be substantially planar, the force with which the hair tip comes into contact with the scalp is weakened, and the cleaning effect inside the pores may not be sufficiently obtained. Further, if the difference between the length H1 of the hair 31 and the length H2 of the cone-shaped protrusion 5 exceeds 5 mm, the tip of the cone-shaped protrusion may not reach the scalp and a sufficient massage effect may not be obtained. There is.

  As a material constituting the cone-shaped protrusion 5, a numerical value (Shore A hardness) measured according to JISK6251 by a durometer type A is 40 degrees or more and 90 degrees or less (more preferably 40 degrees or more and 80 degrees or less). For example, polyolefin resins such as polyethylene and polypropylene, synthetic resins such as nylon and polyacetal, and elastic materials such as urethane rubber, silicone, polyethylene, polypropylene, and elastomer can be used. Among these, it is more preferable to use an elastomer resin in that it can efficiently impart a massage effect to the scalp.

The housing 4 has an opening 41 and is formed in a hollow shape with the inside being a hollow portion 4a. In the illustrated example, a grip 42 is formed on the opposite side of the opening 41. In addition, the opening 41 is provided with a fitting portion 41a into which the fitting claw 24 provided in the base 2 described above is fitted so as to match the position of the fitting claw 24 when the base 2 is assembled.
As described above, the casing 4 functions as a main body or a gripping member of the scalp brush 1 by integrally attaching the base 2 to the opening 41, and is a conventionally known material such as a polystyrene resin. Can be configured without any limitation.
In addition, the grip portion 42 in the illustrated example has a shape with a bulge at the tip so that the user can hold and operate it with one hand, but the present invention is not limited to this. The shape and size can be determined as appropriate.

“Arrangement pattern of hair bundles and cone-shaped projections: arrangement pattern of flocking holes and projection mounting holes”
In the scalp brush 1 of the present embodiment, as described above, the hair bundle 3 is arranged on the outer peripheral portion 21b along the peripheral edge 21a of the brush surface 21 on the brush surface 21, and the cone-shaped protrusion 5 is the hair. It is set as the structure distribute | arranged to the inner peripheral part 21c inside the outer peripheral part 21b by which the bundle 3 was planted. With such a configuration, the scalp brush 1 can obtain both the effect of cleaning the pores of the scalp by the hair 31 and the massaging effect of the scalp by the conical projections 5.

As shown in FIG. 2, the scalp brush 1 according to the present embodiment has six flock holes 22 in the region of the outer peripheral portion 21 b on the brush surface 21 of the base 2, and a total of 10 units. The hair bundles 3 are planted in each of the tuft holes 22 at substantially equal intervals along the peripheral edge 21a.
Further, the scalp brush 1 of the present embodiment is provided with a total of ten cone-shaped projections 5 in the region of the inner peripheral portion 21 c on the brush surface 21 of the base 2. Then, the eight cone-shaped projections 5 are arranged in an elliptical shape, and the two cone-shaped projections 5 are arranged inside the elliptical shape.

(Cone-shaped projections: arrangement pattern of projection mounting holes)
The cone-shaped protrusion 5 has an interval C1 in the range of 5 mm or more and 30 mm or less between the roots of adjacent cone-shaped protrusions 5 in the inner peripheral portion 21c on the brush surface 21 as in the example shown in FIG. It is preferable to be provided and arranged, and it is more preferable that a gap is provided in the range of 7 mm to 22 mm. By setting the interval C1 of each of the plurality of cone-shaped projections 5 within the above range, the hair is effectively divided and the tip of the hair bundle 3 (hair 31) planted on the outer peripheral portion 21b reaches the scalp. Moreover, the outstanding massage effect by the front-end | tip part 5a of the cone-shaped processus | protrusion 5 is acquired. If the distance C1 between the roots of adjacent cone-shaped protrusions is less than 5 mm, the hair tends to be entangled with the cone-shaped protrusions, and the combing of the scalp brush during hair washing is reduced. Moreover, when the distance C1 between the bases of the adjacent cone-shaped protrusions exceeds 30 mm, there is a possibility that a desired massage effect applied to the scalp cannot be obtained.

  Further, the arrangement pattern of the respective cone-shaped projections 5 is not limited to the one based on the elliptical shape as in the example shown in FIG. 2, and for example, as shown in FIGS. 7 (a) to (i). Various arrangement patterns can be used, and an arrangement pattern such as a circle, a horizontal stripe, a checkered pattern, a cross, or a radial pattern can be appropriately employed. Moreover, among these, it is more preferable to arrange in a circular shape (including a perfect circle shape and an elliptical shape) and a horizontal stripe shape.

  Moreover, the number of the cone-shaped protrusion 5 attached to the inner peripheral part 21c on the brush surface 21 has the preferable range of 3-25, and the range of 5-20 is more preferable. If the number of the cone-shaped projections 5 is within the above range, a massage effect can be efficiently applied to the scalp, and the user can obtain a good massage feeling.

(Hair bundle: arrangement pattern of flock holes)
In the present embodiment, 2 to 6 flocking holes 22 arranged on the outer peripheral portion 21b on the brush surface 21 constitute one unit, and the distance between the centers of any two flocking holes 22 in one unit is the shortest part. The distance L1 is 2 mm or more, the longest distance L2 is less than 15 mm, and the shortest center point distance from the center point of an arbitrary unit to the center point of the nearest unit is configured as a range of 10 mm or more and less than 25 mm. Is preferred. In the example shown in FIG. 2, six flock holes 22 are arranged in a rectangular shape to form one unit, and the distance between the centers of any two flock holes 22 in one unit is 3 as the shortest distance L1. .3 mm and the longest part distance L2 is about 8.5 mm, and the shortest center point distance L3 between the nearest unit center points is 16 mm at the shortest part.

In the present embodiment, detailed illustration is omitted by adopting the arrangement form of the flocked holes 22 as described above, but a configuration in which a flocked region and a non-flocked region are arranged on the outer peripheral portion 21 b on the brush surface 21. It is preferable that
Here, the flocked region described in the present invention is a region where the flocked holes 22 are dense, that is, a region where the flocks 3 are concentrated by flocking the hair bundle 3 (the hair 31) in the flocked holes 22. Yes, as described above, the flock holes 22 are arranged in units of relatively short distances. On the other hand, the non-planted region is a region where the flocked hole 22 is not provided on the brush surface 21 or a region where the flocked hole 22 is arranged in a sparse state, and the hair bundle 3 (hair 31) is flocked. It is a region that has not been or has been sparsely implanted. That is, in the example illustrated in FIG. 2, each unit including the six flocking holes 22 is a flocking region, and a gap region between the flocking regions including each unit is a non-flocking region.
In the present invention, as described above, when the flocked holes 22 and the plurality of hair bundles 3 are evenly distributed by the configuration in which the flocked region and the non-flocked region are arranged on the outer peripheral portion 21b on the brush surface 21. In comparison, a high massage effect is obtained, and a high scalp pore cleaning effect is obtained.

Here, in the scalp brush of the conventional configuration, when the flock holes are arranged in an excessively dense state, there is a problem that it is difficult to obtain a feeling of cleaning because the comfort of the hair bundle against the scalp is too weak. is there. On the other hand, if there are too many non-planted areas, the scalp will be too hard to touch and the user will feel pain, which will not be comfortable to use, and the cleaning effect will be reduced. There is a problem that it becomes difficult to hold, and since the cleaning agent is not accompanied when the tip portion of the hair enters the scalp pore, it is impossible to obtain a feeling of cleaning of dirt.
As a result of earnest research conducted by the present inventors, 3 to 9 flocked holes 22, more preferably 4 to 6 flocked holes 22, are used as a unit as a condition for obtaining a sufficient cleaning feeling and a massage effect at the same time. In this case, the shortest distance L1 between the centers of any two flock holes 22 in one unit is 2 mm or more, the longest distance L2 is less than 15 mm, more preferably the shortest distance L1 is 2.5 mm or more and the longest. It is important to configure the part distance L2 to be less than 10 mm and to configure the distance L3 from the center point of any unit to the center point of the nearest unit to be 10 mm or more and less than 25 mm, more preferably 12 mm or more and less than 20 mm. Became clear.

  When the number of flock holes 22 per unit is less than 3, the scalp feels uncomfortable and a sufficient massage effect cannot be obtained. Conversely, when the number of flock holes 22 per unit is 10 or more, the hair bundle 3 in each unit arranged on the brush surface 21 comes into contact with the scalp in a substantially surface contact state, and a massage effect is obtained. In addition, since the hair cannot efficiently enter the scalp pores, the pore removal and cleaning effects cannot be sufficiently obtained.

  If the shortest portion of the distance L1 between the centers of any two flock holes 22 in one unit is less than 2 mm, the hair bundle 3 in each unit will contact the scalp in a surface contact state, and no massage effect will be obtained. Further, since the hair cannot efficiently enter the scalp pores, pore dirt removal and cleaning effects cannot be sufficiently obtained. When the longest portion of the distance L1 between the centers of any two flock holes 22 in one unit is 7 mm or more, the contact feeling with the scalp decreases.

  If the distance L3 from the center point of any unit to the center point of the nearest unit is less than 10 mm, or if the distance from the center point of any unit to the center point of the nearest unit is 25 mm or more, there is no The flocked region B becomes too wide, the cleaning effect is lowered, and the cleaning effect feeling obtained from the appearance is also lowered.

  Further, the shortest center point distance L3 between the nearest unit center points is not particularly limited, but is preferably in the range of 10 mm to 25 mm, and more preferably in the range of 12 mm to 20 mm. If the shortest center point distance L3 between the nearest unit center points is less than 10 mm, the inside of one unit becomes too dense, the actual feeling that the tip of the hair bundle (hair) reaches the scalp is lowered, and the feeling of use is lowered. . Further, if L3 exceeds 25 mm, the inside of one unit becomes too sparse, and the tip of the hair comes into strong contact with the scalp, so that the user feels irritation and the feeling of use decreases, which is not preferable.

  In addition, in the example shown in FIG. 2, although the flocking hole 22 is comprised by the rectangular shape 6 holes, it is comprised by 1 unit, However, It is not limited to this. For example, as shown in FIG. 7A, a unit in which the flocking holes 22 are arranged in three holes in a regular triangle shape may be used. As shown in FIG. 7C, the flocking holes 22 are arranged in parallel with four holes. A total of nine units with five holes can be used, and other units can be determined as appropriate.

(Ratio between the outer peripheral part and the inner peripheral part of the brush surface)
In the scalp brush 1 of the present embodiment, as described above, the hair bundle 3 (hair 31) is planted on the outer peripheral portion 21b along the peripheral edge 21a on the brush surface 21 of the base 2, and from the outer peripheral portion 21b. Also, the conical projection 5 is attached to the inner peripheral portion 21c. In this embodiment, it is preferable that the outer peripheral part 21b in which the flock hole 22 is provided on the brush surface 21 is in the range of 40% or more and 60% in terms of the area ratio with respect to the entire brush surface 21.

  If the ratio of the area of the outer peripheral portion to the area of the entire brush surface 21 of the base 2 is less than 40%, the number of hair bundles (hairs) to be implanted in the outer peripheral portion becomes too small, so that the hair tip is on the scalp. There is a risk that the user will not be able to obtain the actual feeling of reaching the point. Moreover, when the ratio of the area of the outer peripheral part with respect to the area of the whole brush surface 21 of the base 2 exceeds 60%, the number of the cone-shaped protrusions 5 attached to the inner peripheral part is reduced, so that a high massage effect and good The massage feeling and the effect of scratching the hair cannot be obtained sufficiently. In addition, when a hair bundle (hair for hair) made of small-diameter bristle is implanted on the inner periphery of the brush surface, the cone-shaped projections attached to the outer periphery of the hair touch the user's scalp. Is not preferable because there is a possibility that the strength becomes too strong.

  According to the scalp brush 1 of the present embodiment, on the brush surface 21 of the base 2, the hair bundle 3 (hair 31) and the conical projections 5 made of an elastic material have the dimensions and arrangement pattern as described above. For example, even when a person with long hair uses the scalp-like projection 5, the scalp hair 5 can be scraped off and an appropriate massage effect can be imparted to the scalp. Further, the tip of the hair 31 can reach the scalp to effectively clean the inside of the pores, and the user can obtain an excellent cleaning feeling.

  Such a scalp brush 1 has an excellent cleaning effect against dirt on the scalp, pores of the scalp, hair, etc. by using a shampoo agent in a state of foaming on the scalp and on the scalp hair, mainly at the time of washing the hair. . In addition, for example, by applying a massage agent to the scalp and hair, and then brushing it off with the scalp brush 1, the massage agent can quickly spread over the entire scalp and hair and can be massaged efficiently. It is possible to raise the dirt inside the pores and further improve the cleaning effect. Furthermore, when used in combination with a rinsing agent or a conditioner agent, these liquid agents can reach the scalp quickly, and the target component can be efficiently penetrated into the scalp. The usage pattern of the scalp brush according to the present invention is not limited to these, and can be used for various purposes in the scalp and scalp care work.

  As described above, according to the scalp brush 1 of the present embodiment, on the brush surface 21 provided in the base 2, the shape on at least one end side is tapered, and the distal end portion 31a is thinner than the scalp pore. The bristles 3 formed by bundling a plurality of bristles 31 having a diameter are arranged on the outer peripheral portion 21b along the peripheral edge 21a of the brush surface 21, and are made of an elastic material and have a cone shape formed by chamfering the tip portion 5a. Since the protrusions 5 are arranged on the inner peripheral portion 21c inside the outer peripheral portion 21b in which the hair bundle 3 is implanted, a high pore cleaning effect is obtained and a moderate irritation is given to the scalp. A massage effect is obtained.

  Moreover, the hair bundle 3 (hair 31) planted by the outer peripheral part 21b on the brush surface 21 with which the base 2 is equipped has 3 to 9 planting holes 22 into which the hair bundle 3 is planted, and 1 unit. The distance between the centers of any two flock holes 22 in one unit is in the range of 2 mm or more and less than 15 mm, and the distance from the center point of any one unit to the center point of the nearest one unit is Since the hair transplanted into each flock hole 22 arranged as a range of 10 mm or more and less than 25 mm, the scalp is moderately stimulated not only by the cone-shaped projections 5 but also by the hair 31, A more excellent massage effect and cleaning effect inside the scalp pores can be obtained.

  Further, in the scalp brush 1 of the present embodiment, the cone-shaped projections 5 and the hair bundles 3 (hairs 31) are densely packed in the outer peripheral part 21b and the inner peripheral part 21c on the brush surface 21, respectively. Since it has both a region and a sparse region, a high massage effect can be obtained as compared with a conventional scalp brush that is configured to give an appropriate feeling of stimulation to the scalp and distribute it evenly on the brush surface.

In the scalp brush according to the present invention, as shown in the example shown in FIG. 8, at least one or more through-holes are formed so as to penetrate the base 12 substantially at the center and / or peripheral edge of the brush surface 13. In the illustrated example, an elliptical through hole 14 is formed in the vicinity of the approximate center of the brush surface 13 provided in the base 12. By providing such a through hole 14, the scalp brush is configured to open to the outside when the base 12 is attached to the housing (see the housing 4 in FIG. 1 and the like). . By having such a configuration, when using the scalp brush, water or a cleaning agent or the like can enter the hollow scalp brush to drain water from the through hole 14, Even when the scalp brush is repeatedly used over a long period of, for example, about six months, it can be used and stored cleanly.
As a location where the through hole is provided, in addition to the substantially central portion and / or the peripheral portion of the brush surface 13, it may be configured to be provided in a gripping portion of the housing, and the shape, position, size, and the like of the through hole are appropriately determined. Is possible.

  Hereinafter, examples for demonstrating the scalp brush and scalp pore cleaning tool of the present invention will be described, but the present invention is not limited to these examples.

[Production of scalp brush]
In the following procedure, a hair bundle is produced using the hair as shown in FIG. 3, and a cone-shaped projection as shown in FIG. 5 is created, and the hair bundle and the cone-shaped projection are attached to the base. A scalp brush sample as shown in FIG. 1 was prepared by attaching the base to the housing.

(Preparation of base)
First, as shown in FIG. 1 and FIG. 2, the planar view has a substantially elliptical shape of 79.3 × 64.3 mm and a thickness of 4.5 mm on the outer peripheral portion 21 b of the brush surface 21. Six flocking holes 22 having a diameter of 1.5 mm were arranged in a rectangular shape to form one unit, and a total of 10 units (total number of flocking holes: 60 holes) were arranged. At this time, the distance between the centers of any two flock holes 22 in one unit is 3.3 mm at the shortest part distance L1 and about 8.5 mm at the longest part distance L2, and between the nearest unit center points. The shortest center point distance L3 was 16 mm. At this time, the outer peripheral region on the brush surface was about 55% of the outer region along the periphery of the brush surface.
Further, in the region of the inner peripheral portion 21c of the brush surface 21, a protrusion mounting hole (protrusion mounting hole 23) for inserting and mounting the cone-shaped protrusion 5 is provided, and eight protrusion mounting holes are arranged in an elliptical shape. A total of 10 pieces were formed in an arrangement in which two protrusion mounting holes were arranged inside the elliptical shape.

(Production of hair)
Conventionally known that a raw yarn of a 190 μm diameter hair made of polybutylene terephthalate (PBT) resin material is cut into equal dimensions and immersed in a high-concentration NaCl solution heated to a specified temperature for chemical processing Using this method, both ends were processed into a taper shape to obtain bristles 31 for a scalp brush as shown in FIG. The diameter of the hair (thin diameter bristle) 31 obtained by this procedure at a portion 0.1 mm from the tip was about 20 μm, and the diameter of the thickest portion was about 0.19 mm.

(Flocking hair)
Each flock hole 22 is obtained by flocking the bristles 31 having both ends tapered into a bundle of approximately 15 bristles and flocking the bristles 31 from the center to each flock hole 22 of the base 2. The hair bundle 3 was attached. At this time, the bristle (hair bundle) 31 had an average length of about 14 mm (± 0.5 mm) from the brush surface 21 to the end surface 31 b of the base 2.

(Production of cone-shaped projections)
As the cone-shaped projection 5, a styrene-based elastomer resin (hardness: 60 A) was used, and the cone-shaped projection 5 and the projection substrate (not shown) having the cone-shaped projection 5 formed on the surface were produced by integral molding. . At this time, the conical projection 5 was formed with a diameter of about 0.6 mm at a portion 0.1 mm from the tip and a diameter of the base portion of the projection of 7 mm. Further, the tip portion 5a of the cone-shaped protrusion 5 was chamfered into a curved surface.

(Preparation of scalp brush)
The base 2 in which a plurality of hair bundles 3 are implanted in the outer peripheral portion 21b on the brush surface 21 and the protrusion mounting hole (protrusion mounting hole 23) is formed in the inner peripheral portion 21c, obtained by the above procedure, and The substrate on which the conical protrusions 5 were formed on the surface was fitted into the opening 41 of the housing 4 as shown in FIG. 1 and attached integrally to obtain the scalp brush 1 of Example 1. At this time, the base 2 is superposed on a substrate (not shown) on which the conical protrusions 5 are formed, and the conical protrusions 5 are inserted into the protrusion mounting holes formed in the base 2, so that the brush surface 21 It assembled so that it might protrude.
On the brush surface 21 of the scalp brush 1 assembled as described above, the dimension obtained by subtracting the length H2 of the cone-shaped protrusion 5 from the length H1 of the hair bundle 3 (hair 31) from the brush surface 21. Was 2.5 mm. On the brush surface 21, the interval C <b> 1 provided between the bases of the respective cone-shaped protrusions 5 is 15 mm at the longest portion and 10 mm at the shortest portion.

In addition, the number of flock holes per unit, each size and arrangement, and the number, each size and arrangement of cone-shaped projections are shown in Tables 1 and 2 below, and FIGS. 7 (a) to (i) and Except for the specifications shown in FIGS. 9A to 9F, scalp brushes of Examples 2 to 15 and Comparative Examples 1 to 6 were obtained by the same procedure as described above.
In the scalp brushes of Examples 13 and 14, the outer peripheral portion where the hair bundle is implanted on the brush surface is an area of about 35% and about 65% on the outer side along the periphery of the brush surface, respectively. It is. In the scalp brushes of Examples 13 and 14, the number of holes in one unit and the dimensions of L1 and L2 are the same, but the areas from the peripheral edge of the outer peripheral portion are about 35% and about 65%, respectively. Therefore, the dimension of L3 is 20 mm in Example 13 and 10 mm in Example 14. This is because each unit composed of each hair bundle is arranged in only one row along the periphery in the thirteenth embodiment (see FIG. 7 (i)), but in the fourteenth embodiment, a detailed illustration is provided. This is because the units are arranged in two rows along the periphery.

[Evaluation method]
Using the scalp brushes of each Example and Comparative Example obtained as described above, the following method was used for “feeling of cleaning inside the pores”, “feeling of scalp massage”, and “ease of moving the scalp brush during hair washing” It was evaluated with.
As a method of using the scalp brush, a commercially available shampoo (trade name: Plant Story; registered trademark, manufactured by Lion Corporation) was used. First, each panel (subject) applied shampoo to the scalp and hair in an appropriate amount. After foaming so that the foam spreads over the entire scalp, the hair was washed using each sample of scalp brush. At this time, the hair washing time using each sample of the scalp brush was set to about 3 minutes, and the scalp brush was moved uniformly and washed while foaming. After rinsing the hair and the entire scalp with hot water, each panel explains the `` feeling of cleaning inside the pores '', `` feeling of scalp massage '' and `` easy to move the scalp brush when washing hair '' Sensory evaluation was performed according to the evaluation criteria.
In addition, as a panel (subject) in each sensory evaluation test, a female panel (n = 30) was used, and the length of the hair on each panel was “length from ear to shoulder: total of 5”, Panels were selected as “length within 10 cm downward from shoulder: 15 people in total” and “length over 10 cm to 20 cm from shoulder: 10 people in total”, and evaluation was performed under the same conditions.

(Internal pore cleaning feeling)
About each sample (Examples 1-15, Comparative Examples 1-6) of the said scalp brush, each paneler (n = 30 persons) performs scalp washing operation using a shampoo, and the washing | cleaning feeling inside a pore is 5 steps ( Sensory evaluation was performed according to the number of panelists who felt good or slightly good, and was evaluated according to the following four-step criteria.
The evaluation results are shown in Tables 1 and 2 below.
(1) ◎: More than 80% of panelists answered that it is good (high effect)
(2) ○: 60% or more and less than 80% (effective)
(3) Δ: Panelers who answered that they are good are 40% or more and less than 60% (not very effective)
(4) ×: Less than 40% of panelists answered that they were good (no effect)

(Scalp massage feeling)
About each sample (Examples 1-15, Comparative Examples 1-6) of the brush for the scalp, each paneler performs scalp washing operation using a shampoo, and the scalp massage feeling is the same as the above "feeling of washing inside pores" Sensory evaluation was performed based on the criteria. And it evaluated by 4 steps | paragraphs with the same reference | standard as the above-mentioned, and the evaluation result was shown in the following Table 1 and Table 2, respectively.

(Ease of moving scalp brush when washing hair)
About each sample (Examples 1-15, Comparative Examples 1-6) of the said scalp brush, each paneler performs scalp washing | cleaning operation using a shampoo, The above-mentioned "inside of pores" Sensory evaluation was performed according to the same criteria as “feeling of washing” and “feeling of scalp massage”. And it evaluated by 4 steps | paragraphs with the same reference | standard as the above-mentioned, and the evaluation result was shown in the following Table 1 and Table 2, respectively.

  Tables 1 and 2 show the flocked hole specifications, the cone-shaped projection specifications, and the evaluation results in each sample of the scalp brush.

[Evaluation results]
As shown in the results shown in Table 1 and Table 2, the hair bundle 3 (hair 31) is arranged on the outer peripheral portion 21b with an appropriate size and arrangement on the brush surface 21, and the cone-shaped protrusion 5 The scalp brushes of Examples 1 to 15 are arranged in the inner peripheral part 21c on the inner side of the outer peripheral part 21b with an appropriate size and arrangement. The “scalp internal feeling of cleaning”, “scalp massage feeling”, and “hair washing” The evaluation in each sensory test of “Ease of moving scalp brush at the time” gives an evaluation result of “◎” or “○”, which gives an excellent washing feeling and massage feeling, and also has excellent usability during hair washing. It became clear. In addition, among the samples of each of the examples, the scalp brush of Example 13 in which the outer peripheral portion where the hair bundle is implanted on the brush surface is an area of about 35% has an evaluation of scalp massage feeling of “◎”. As a result, the scalp brush of Example 14 in which the outer peripheral portion had an area of about 65% had an evaluation result of “◎” in the pore internal cleaning feeling.

On the other hand, the scalp brush of Comparative Example 1 in which the hair bundle (hair for hair) was not implanted on the outer peripheral portion on the brush surface was inferior in the cleaning action, and therefore the evaluation of “feeling of cleaning inside pores” was “x”. In addition, the evaluation of “scalp massage feeling” was also slightly inferior to “△”.
In addition, the scalp brush of Comparative Example 2 in which no cone-shaped protrusions were attached to the inner peripheral portion on the brush surface was inferior in the massage effect on the scalp, so the evaluation of “scalp massage feeling” was a result of “x”. In addition, the evaluation of “feeling of cleaning inside pores” was slightly inferior to “△”.
Further, on the brush surface, the scalp brush of Comparative Example 3 in which the cone-shaped protrusions are attached to the outer peripheral portion, the hair bundle is implanted in the inner peripheral portion, and the arrangement is the reverse of the provisions of the present invention. The evaluation of “feeling of cleaning inside pores” was a result of “x”, and the evaluation of “feeling of scalp massage” was “△”, which was slightly inferior.

In addition, the scalp brush of Comparative Example 4 in which no conical protrusions are attached on the brush surface and the hair bundle is planted on the entire brush surface has a “feeling of cleaning inside the pores”, “feeling of scalp massage” and In each sensory test, “Ease of moving scalp brush when washing hair” was evaluated as “x”.
Further, the scalp brush of Comparative Example 5 in which the hair bundle is not implanted on the brush surface and the cone-shaped protrusions are attached to the entire brush surface has the “feeling of cleaning inside the pores” and the “scalp for washing the hair” The evaluation in each sensory test of “Ease of moving the brush” was “x”, and the evaluation of “scalp massage feeling” was “△”, which was slightly inferior.
In addition, the scalp brush of Comparative Example 6 in which both the cone-shaped protrusions and the hair bundles are attached over the entire brush surface has a “feeling of cleaning inside the pores”, “feeling of scalp massage”, and “scaling the scalp brush during hair washing”. The evaluation in each sensory test of “Ease” was “x”.

  From the above evaluation results, when only one of the cone-shaped projections or hair bundles (hairs) is attached to the entire surface of the scalp brush surface, “inside pore cleaning feeling”, “scalp massage feeling” ”And“ Ease of moving the scalp brush during shampooing ”are inferior, and even when only one of the cone-shaped projections or hair bundles is arranged in a specified region on the brush surface, It can be seen that either “feeling of washing” or “feeling of scalp massage” is greatly inferior. In addition, on the brush surface, conical projections are arranged on the outer peripheral portion and hair bundles are arranged on the inner peripheral portion, and the arrangement opposite to the arrangement defined in the present invention is also used. It can be seen that either "" or "Scalp Massage" is greatly inferior.

  On the other hand, as defined in the present invention, on the brush surface, the bristles (hairs) are arranged in an appropriate size and arrangement on the outer peripheral portion, and the cone-shaped projections are located on the inner side of the outer peripheral portion. The scalp brushes of Examples 1 to 15 arranged with appropriate dimensions and arrangement on the periphery can satisfy both the scalp massage effect and the cleaning effect inside the pores at the same time. However, when a long user uses the hair, the hair does not get entangled with the cone-shaped protrusions and the hair bundle, and it can be seen that the hair has very high usability.

  From the results of the examples as described above, the scalp brush of the present invention can satisfy both the scalp massage effect and the cleaning effect inside the pores at the same time, and is further excellent in usability. It became clear.
