Description

Brush for scalp pores and scalp pores {BRUSH FOR WASHING SCALP PORES AND INSTRUMENT FOR WASHING SCALP PORES}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scalp pore cleaning brush that can effectively remove contamination not only on the scalp surface but also inside the pores by using a hair having a diameter that is thinner than the scalp pores. The present invention relates to a scalp pore cleaning brush and a scalp pore cleaning tool that can be used when used together with a cleaning agent for cleaning the scalp or scalp skin.

Conventionally, various things are known as a brush for washing a hair and a scalp, For example, the brush which has a spherical body at the tip of a bristle (refer patent document 1), and a spherical body A combination of a hair having a shape and a hair having no spherical shape (see Patent Document 2), having a roughly conical shape whose outer peripheral surface in the longitudinal direction is a curved surface (see Patent Document 3), It is proposed that there are small protrusions in which the tip contacts the scalp and flexes flexibly (see Patent Document 4), the bristle tip opens (see Patent Document 5), and the like.

However, all of these conventional brushes have a massage effect on the scalp of the bristle tip at the time of trituration, but since the bristle tip is large, the inside of the pores of the scalp cannot be cleaned, and it is discharged from the pores and is free of contamination or odor. There is a problem that the sebum that causes it cannot be removed.

In addition, a scalp pores cleaning brush composed of thin hairs with fine hairs and Taekyung hairs, comprising: 1-200 μm in diameter of scouring hairs made of resin and taekyung hairs on a first substrate. Through-holes are alternately formed, resin-made taekwondo hairs having a diameter of about 1 to 5 mm are formed on the second substrate, and the tae-kyong hairs of the second substrate are inserted through the insertion holes of the first substrate and the first The thing of the structure which combined the 2nd board | substrate is proposed (for example, refer patent document 6).

In addition, combing can be easily and easily entangled in the hair, and in particular, as a brush for scalp pore cleaning, which can clean not only the surface of the hair and the scalp but also the pores by using in combination with a shampoo or a hair growth agent. It is proposed that a plurality of cross section elliptical hairs are arranged at regular intervals on the cross-section, and a bundle of fine hairs is transplanted between the cross section elliptical hairs (for example, Patent Documents 7, 8). See).

According to the brush for scalp pore cleaning described in Patent Literatures 6 to 8, since the hair of a large diameter is planted, a high scalp massage effect can be obtained. However, in the scalp pore cleaning brush of Patent Documents 6 to 8, since the tip portion of the Taepok hair is larger in diameter than the pores, it is difficult to penetrate into the pores, and there is a problem that it is difficult to obtain the pore cleaning effect. In addition, since the hair density of the narrow hairs provided between the large hairs is low, the washing power is insufficient, and the inside of the scalp cannot be cleaned, and the pores of the scalp pores can be cleaned from the pores in the same manner as the brushes for scalp pores described in Patent Documents 1 to 5. There is a problem that the sebum that is discharged to cause contamination or odor cannot be removed.

In order to solve the problem of the cleaning power inside the pores, by using a hair having a diameter that is thinner than the scalp pores at the tip, it is possible to effectively remove the contamination inside the pores, and the hair bundle formed by a plurality of hairs bundled together. A brush for scalp pore cleaning with equal intervals in the range of 3 to 30 mm is proposed (for example, Patent Document 9). However, in the scalp pore cleaning brush described in Patent Document 9, the use of a narrow hair is excellent in the cleaning effect inside the pores, but there is a problem that the massage effect on the scalp is low.

In addition, in the scalp pore cleaning brush having a structure in which a protrusion provided with a protrusion against the scalp is attached to the body, when the inside of the body is formed in a hollow shape, a composition such as a shampoo or a hair growth agent in addition to the washing water penetrates into the inside. In addition, since the inside of the body is contaminated, mold, etc., contamination may also occur on the surface of the base surface, and there is a problem that it is difficult to keep the scalp pore cleaning brush clean.

Here, the material in which the projections are attached to the base, that is, the hair part where the bristle is planted is made into a deformable material, and the water and the composition remaining inside the body can be easily formed by a configuration that can be easily detached from the body. It can drain and make it possible to keep clean.

However, when forming a brush using hair bundles in which a plurality of bristles are bundled, it is necessary to use a hard resin represented by polypropylene or the like as the material of the hair part (expectation). It becomes difficult to perform desorption by.

In order to solve such a problem, for example, it is conceivable to completely block the bonding portion of the scalp pore cleaning brush, which has a hollow shape, and to prevent the ingress of water or the composition into the sealed state. When manufacturing the base of the sealed structure, since technical difficulty is high and manufacturing cost rises, there exists a problem that practical use as a commodity is difficult.

[Scale Pore Cleaning Brush]

In the scalp pore cleaning brush 1 of the present embodiment, at least one end side has a tapered shape, and a bristle bundle 3 in which a plurality of bristles 31 having a diameter smaller than the tip end portion 31a than the scalp pores are bundled together. ) And a base 2 having a seeding surface 21 provided with a plurality of seeding holes 22 in which the hair bundle 3 is seeded, and the inside of the seedling hole 22 is external to the seedling hole 22. The hair | bristle bundle 3 is transplanted by the density of the state which is not observed in the state, and the tip part (refer to the front-end | tip part 31a of the bristles 31) of the some hair | bristle bundle 3 on the seeding surface 21 is roughly one. A hair growth area A and a hairless area B (refer to FIG. 2), which form a plane and are densely packed with the tuft holes 22, are arranged in outline.

In addition, as shown in FIG. 1A and FIG. 1B, the cleaning brush 1 of this embodiment is also hollow shape which has the opening part 41 (FIG. 1A and FIG. 1B, the hollow part 4a of FIG. 2). In addition to the body 4 formed in the above, the base 2 is integrally attached to the opening 41 of the body 4. Moreover, the base 2 is provided with the through-hole 21a which penetrates the base 2 in the outline center part of the seedling surface 21, and the notch part 21b, 21c in the peripheral part of the seedling surface 21 is provided. Is formed, a through hole formed of the notches 21b and 21c and the opening 41 of the body 4 is formed.

The base 2 has a plurality of hair bundles 3 made of bristle 31 attached thereto, and a plurality of hair growth holes 22 are formed in the hair transplantation surface 21 in order to plant the hairs 3. In addition, the base 2 of the example of illustration is formed in flat elliptical flat shape by planar 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 tuft hole 22 are not particularly limited. For example, the tuft hole 22 may be any size necessary for weaving about 10 to 50 bristles per one hole. In addition, although the shape of the tuft hole 22 can be generally circular, for example, as shown in Unexamined-Japanese-Patent No. 2000-50955, it is a non-circle for the purpose of improving the quality of a brush and the improvement of manufacturing efficiency. You may form in a non-shaped shape.

In addition, the tuft hole 22 needs to form the arrangement pattern on the tuft surface 21 according to the tuft pattern of the hair | bristle bundle 3, For example, in the example shown in FIG. 2, it combines at predetermined intervals. The hair-fed holes 22 formed into four holes form one unit, and each of these units is appropriately arranged on the woolen surface 21. In the present embodiment, details will be described later, but the hair-fed holes 22 are crowded. The area A and the unhairing area B are disposed respectively.

In the base 2 of the illustrated example, the fitting pawl 23 to be provided in the body 4 to be described later is formed on an oblique line on the short side of the base 2 in an elliptical shape. Although arranged so as to face each other, the means for attaching the base 2 to the body 4 is not limited to this. For example, the fitting pawl may be arranged at a position different from that shown in the example on the base, or may be configured to attach the base to the body by screwing or the like.

In the base 2 of the illustrated example, as described above, the through-hole 21a is provided to penetrate the base 2, and the notches 21b and 21c are formed at the periphery of the seedling surface 21. By this, the through hole which consists of these notch parts 21b and 21c and the opening part 41 of the body 4 is comprised, and when the base 2 is attached to the body 4 mentioned later, the cleaning brush 1 ) (See the internal space 4a shown in FIGS. 1A and 1B) is configured to open to the outside.

The hair | bristle bundle 3 consists of several bristles 31 tied together.

In the bristle 31, as shown in FIG. 3, the shape of at least one end side becomes a taper shape, In the example of illustration, the front-end | tip part 31a of both ends is formed in taper shape. In addition, the tip portion 31a has a diameter d at least near the end face 31b of which is thinner than the pores of the scalp.

As shown in the example, the tip of the tip portion 31a is formed on the scalp-like hair by forming the tip portion 31a in a tapered shape with respect to the filaments constituting the bristle 31 (see cross section 31b). Since the tip portion 31a is easily bent by the weak force generated at the time of contact, the mothership can pass between the hairs and reach the pores of the scalp.

Moreover, since the strength of the tip part is weak in the tapered shape, the mother ship may bend when washing or massaging the scalp with an extremely strong force, which may make it difficult to clean the pores. For this reason, as a load which the user applied to the brush at the time of scalp cleaning, it is preferable to set it as about 300-1000g.

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

Here, even with the conventional brush for scalp pores, it is considered that it is possible to wash the scalp pores by using a fine hair of dense hair without a large diameter of hair. However, the diameter of human hair varies depending on race, sex, age, and the presence of habitual hair to sleep only on one side, but in general Japanese is about 40 to 100 μm, and on average 70 μm, some hairs The size of one of these pores is considered to be equal to or larger than the diameter of the hair and is considered to be 70 µm or more on average.

However, the thinner than the size of the pores as described above, the diameter is thinner, and when the fine hairs having a diameter that can be inserted into the pores are densely planted on the woolen surface, and the brush is constructed, Even when trying to hold the hair bundle of the brush tightly on the hair roots, many people tend to inhibit the progression of the narrowing hair for the person having the hair of the normal size. For this reason, since the number of narrow hairs easily bends and the number which can reach the hairs for narrow diameters becomes small, there exists a problem that a desired pore washing effect is difficult to be obtained.

In the scalp pore cleaning brush of the present invention, in order to remove contamination such as lipids in the pores, the tip portion 31a uses brush hair thinner than the diameter of the pores. By bristling the bundled hair | bristle bundle 3 in the pattern mentioned later, the bristle | bristle hair 31 (hair | bristle bundle 3) is easy to reach the pores of a scalp to the end, without impeding movement to hair, and excellent washing | cleaning The effect can be obtained. In addition, since hair falling out of the scalp is hardly entangled with the bristle 31 and can be easily released even when entangled, for example, excellent maintenance property can be obtained.

It is preferable to make the hair length (hair length) of the bristle 31 which comprises the hair | bristle bundle 3 into the range of 5-50 mm. More preferably, it is the range of 5-30 mm.

If the length of the hair is shorter than 5 mm, there is a fear that the hair is impeded and the hair (hair bundle) does not reach the scalp pores. Moreover, when the hair length of the bristle | bristle 31 is longer than 50 mm, a bristle tends to bend and a tip part will become hard to reach the bare skin and a pore of a scalp.

In addition, there may be a slight deviation in the hair length of the hair-frilled bristle 31 (hair bundle 3), but roughly 90% or more of all the hair-frilled whole bristles 31 is 5-50 mm. It is desirable for quality to fall in the range of hair length.

It is preferable that the number of hairs of the bristles per one hole of the hair-stripping holes 22 is made into the density of the state which the inside of the hair-stall holes 22 cannot observe from the outside, Specifically, the hair-stripping of the bristle 31 per one hole is specifically, It is preferable that the number is 10-50. When the number of hairs of the bristle 31 becomes small enough to observe the inside of the hairsitting hole 22 from the outside, the hair which fell into the hair | bristle bundle 3 becomes entangled, and since it becomes difficult to remove hair, Not desirable Moreover, since the washing | cleaning agent, rinse agent, etc. which are used at the time of hair washing infiltrate into the hair-frilling hole 22, and it becomes easy to fill up, it is not preferable for the hygiene of the scalp pore cleaning brush.

On the other hand, in the scalp pore cleaning brush according to the present invention, in which the number of bristles that become a density in a state in which the inside of the tuft hole 22 cannot be observed from the outside is planted, the hairs missing in the hair bundle 3 become entangled. Since there is no gap that can be observed inside the tuft hole 22, the cleaning agent and the like are prevented from entering and filling up.

In addition, when the number of hairs of the bristle 31 (hair bundle 3) is small with respect to the cross-sectional area of the bristle hole 22, a slight gap will arise between the bristle 31, and an individual difference may be caused by the user of the scalp pore cleaning brush. However, hair having a thickness of approximately 70 µm is caught in a slight gap between the bristles 31, and there is a risk of becoming extremely difficult to remove.

Below, the reference example of the hair-plant density of the bristle | bristle 31 with respect to the hair-piercing hole 22 is demonstrated.

For example, when weaving the bristle 31 whose diameter is 190 micrometers in the filament center part in the bristle hole 22 which became 1.5 mm in diameter, 21 bristle | bristle 31 31 is made into the flat line of 0.25 mm thickness. When the hair is fixed by the center of the bristle 31 at the center of the bristle 31, the inside of the bristle hole 22 can be made into a density which cannot be observed from the outside. The cross-sectional area of the woolen hole 22 is 0.095 × 0.095 × 3.14 when the cross-sectional area is examined with respect to such a state in the woolen hole 22. It becomes * 21x2 = 1.19mm <2>, and 67% of the cross-sectional area of the hair removal hole 22 is occupied by the bristle | bristle 31. In FIG.

Moreover, as a result of earnest experiments by the present inventors etc., when the number of hairs of the bristle 31 is 13, the ratio of the cross-sectional area of the bristle 31 to 42% of the bristle hole 22 becomes 42%. The ratio of 42% was found to be the boundary between the state in which the inside of the tuft hole 22 was not observed from the outside and the viewable state. When the ratio of the cross-sectional area of the bristles 31 to the cross-sectional area of the tuft holes 22 is less than 42% as a boundary, the inside of the tuft holes 22 becomes a state that can be observed from the outside, and in such a state, the diameter is roughly Hair having a thickness of about 70 μm tends to be entangled with the bristle 31.

In view of the ease of hair entanglement, when the ratio of the cross-sectional area of the bristle 31 to the cross-sectional area of the tuft hole 22 is less than the boundary of 42%, the hair tends to get entangled in the bristle 31, It is preferable to make the said ratio 42% or more and 85% or less. When the proportion of the bristle 31 in the tufts of holes 22 exceeds 85%, the base 2 tends to crack from the tufts of holes 22 as a starting point, and the bristles of bristles 31 are opened. There is concern and undesirable.

In addition, when the number of seedlings with respect to the tuft holes 22 is less than 10, the washing | cleaning effect of the scalp pores falls, and when there are more than 50 seedlings, it is necessary to form a tuft hole with a large diameter in the base 2, A cleaning agent, a rinse agent, and the like, used at the time of hair washing, in the tuft hole 22, are easily infiltrated and filled, which is not preferable for the hygiene of the scalp pore cleaning brush.

In addition, there may be a deviation in the number of the hair-stripping, and the number of the number of hairs of the bristles 31 is 10 to 50 at approximately 90% or more in the hair-stripping holes 22 in which the bristle 31 (hair bundle 3) is planted. It is preferable in quality that it exists in the range.

Although it does not restrict | limit especially about the material of the filament which comprises the bristle 31 used in this embodiment, Polybutylene terephthalate (PBT), polyethylene terephthalate (PET), and polytrimethylene terephthalate which are general resin materials (PTT), nylon, polyester or the like is suitable. In addition, for example, as described in Japanese Patent Application Laid-Open No. 11-253236, for the purpose of improving aesthetics and the like, other components are mixed with a raw material of a synthetic resin main body, or an antimicrobial agent for the purpose of improving durability. It is also possible to use what added etc.

In the case of using a material having a hard metal or the like as the material of the bristle 31, since the strength can be ensured even if the filament diameter is thin, not only the tapered filaments as shown in FIG. 3 or 4 but also the straight hair It is also possible to use a shape of straight. However, in the case where such a metal-like filament of the straight shape is used, the missing cut surface becomes a sharp shape when the bristles are bent at the time of use of the brush, which damages the bare skin of the scalp at the time of massage, which is not preferable in terms of safety.

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

In addition, as a method of planting the hair | bristle bundle 3 which the plurality of bristle | bristle bundles 31 is bundled in the hair-planting hole 22 of the base 2, for example, the hair removal apparatus generally used for toothbrush manufacture etc. is dedicated (轉 用), it can be used without any limitation, and there is no limitation also with respect to the form of such a tuft. As such a hair removal apparatus, it is possible to use the manufacturing apparatus of Unexamined-Japanese-Patent No. 2000-93233 etc., for example.

And the base 2 in which the hair | bristle bundle 3 (bristle bristle 31) was planted is normally attached to a holding member, such as a handle, is packaged, and becomes a brush product. In this embodiment, base 2 is mentioned later. By attaching to the body 4 to be used, it is set as the cleaning brush 1. Here, as shown, for example, in Japanese Patent Application Laid-Open No. 2001-46149, for the purpose of improving the quality of the brush (hair bundle 3) after the hair removal, etc., the base 2 after the hair removal of the hair bundle 3 which is an intermediate product is used. With regard to the method of performing any treatment, such as performing a heat treatment by cooling or heating, the present invention can be applied within a range that does not impair the effects of the present invention.

The body 4 has the opening part 41 and is formed in the hollow shape which became the hollow part 4a inside, and in the example of illustration, the holding part 42 is formed in the opposite side to the opening part 41, and is formed. . In addition, the opening part 41 is arrange | positioned so that the fitting part 41a which the fitting pawl 23 with which the above-mentioned base 2 is fitted may fit in the position of the fitting pawl 23 at the time of assembling the base 2. It is.

As described above, the base 2 is integrally attached to the opening 41 to function as a main body or gripping member of the scalp pore cleaning brush 1, and the like, such as polystyrene-based resin, A conventionally known material can be used without any limitation.

In addition, although the holding part 42 of the example of illustration is made into the shape which provided the bulging part in the front end so that a user can hold and operate with one hand, it is not limited to this, As for the shape and size of a holding part, Can be determined appropriately.

"Arrangement form of hair | bristle bundle (arrangement pattern of tuft hole)"

In the scalp pore cleaning brush 1 of the present embodiment, as described above, the tip portions of the plurality of hair bundles 3 (see the tip portions 31a of the bristle 31) are roughly one on the seeding surface 21. On the hair-planting surface 21, the hair-growing area | region A and the hairless-growth area | region B which are densely piled are arrange | positioned, respectively, and are comprised in the hair-planting surface 21, and is comprised.

In the present embodiment, on the hair transplantation surface 21, the hair transplantation holes 22 are made into 2 to 6 one unit, and the distance between the centers of the arbitrary two places of the hair transplantation holes 22 in one unit is the shortest part. The distance L1 is 2 mm or more and the longest distance L2 is less than 7 mm, and the shortest center point distance from the center point of any unit to the center point of the nearest unit is 7 mm or more and less than 10 mm. It is preferable to be comprised as a range. In the example shown in FIG. 2, since the tuft hole 22 arrange | positions four holes in a square shape, it becomes one unit, and the distance between the centers of the arbitrary two tuft holes 22 in one unit is the shortest distance. The unit having a length of 3 mm at L1 and a length of about 4.24 mm at the longest distance L2, and the shortest center point distance L3 between the closest unit center points is 9 mm at the shortest part, and the next closest unit. The next shortest center point distance L4 between the center points is about 12.7 mm. In addition, in the example of illustration, the clearance gap S between each unit is set to 6 mm at the distance between the centers of the tuft holes 22.

In the present embodiment, by forming the tuft holes 22 as described above, as illustrated in FIG. 2, the tufted area A and the unplanted area B are disposed on the seedling surface 21. It is preferable to set it as the structure which becomes.

In the hair growing region A described in the present invention, the hair bundle 3 (hair bristle 31) is implanted into a region where the hair growth holes 22 are concentrated, that is, the hair growth holes 22 are used to form the hairs 3. It is an area | region which dense and it is comprised by setting the tuft hole 22 by the unit of a comparatively short distance as mentioned above.

On the other hand, the unhairing area | region B is the area | region which is not provided with the hairdressing hole 22 or the hairdressing hole 22 arrange | positioned in the coarse state on the hair-planting surface 21, The hair | bristle bundle 3 ( (31)) is not planted, or is a region planted in a loose state.

That is, in the example shown in FIG. 2, each unit which consists of four-hole tuft hole 22 is a hair transplantation area A, and the clearance gap area | region between the hair transplantation areas A which consists of each unit is an unhairing area B )to be.

In the present invention, as described above, the hair growth hole 22, that is, the plurality of hair bundles 3 are evenly formed by the arrangement in which the hair growth area A and the unhairing area B are arranged on the hair growth surface 21. Compared with the case of distribution, a high massage effect can be obtained and a high scalp pore cleaning effect can be obtained.

When the hair follicles are evenly arranged in a state in which the hair follicles are too dense as in the conventional brush for scalp pore cleaning, the feeling of touching the scalp of the hair bundle is too weak to obtain a feeling of washing. Conversely, if there is too much ignorance area, the contact with the scalp is so strong that the user feels pain and feels uncomfortable to use, and it is difficult to support a cleaning agent or the like at the front end of the hair, There is a problem in that it is not possible to obtain a cleaning feeling of contamination because no cleaning agent is involved when entering.

As a result of earnest research by the present inventors etc., as a condition that sufficient washing | cleaning feeling of a contamination and a massage effect are acquired simultaneously, the 3-5 hole hair-planting hole 22, More preferably, the 4-5 hole hair-planting hole 22 In this case, the distance between the centers of the arbitrary two tuft holes 22 in one unit in this case is 2 mm or more for the shortest part L1 and less than 7 mm for the longest part L2, more preferably the shortest. The part is made 2.5 mm or more and the longest part is less than 4.5 mm, and the distance L3 from the center point of an arbitrary unit to the center point of the nearest unit is 7 mm or more and less than 10 mm, More preferably, it is 8 mm or more and 9.5 mm It became clear that it is important to comprise below.

When the number of holes of the tuft hole 22 per unit is less than 2, the contact feeling to the scalp is bad and a sufficient massage effect cannot be obtained. On the contrary, when the number of holes of the tuft hole 22 per unit is set to 7 or more, since the hair | bristle bundle 3 in each unit arrange | positioned on the tuft surface 21 contacts a scalp in a rough surface contact state, a massage effect will be performed. Since it is impossible to obtain, and the feature is not able to efficiently enter the scalp pores, the removal and cleaning effect of the pore contamination is not sufficiently obtained.

When the shortest part of the distance L1 between the centers of two arbitrary hair transplant holes 22 in one unit is less than 2 mm, since the hair | bristle bundle 3 in each unit contacts a scalp in surface contact state, a massage effect will be exerted. Since it is impossible to obtain, and the feature is not able to efficiently enter the scalp pores, the removal and cleaning effect of the pore contamination is not sufficiently obtained. When the longest part L2 of the distance between the centers of two arbitrary tuft holes 22 in one unit is 7 mm or more, the contact feeling to a scalp will fall.

When the distance L3 from the center point of any unit to the center point of the closest unit is less than 7 mm, the hair growth hole is made too dense, and the hair feel of contact with the scalp is too weak to obtain a feeling of washing. In addition, when the distance from the center point of an arbitrary unit to the center point of the nearest unit is 10 mm or more, the ignorance hair | bristle area B becomes too wide, and the front part of the bristle | bristle 31 (bristle bundle 3) etc. (cleaning | cleaning agent 3) is removed. It becomes difficult to support to 31a).

Further, it is more preferable that the distance L4 to the center point of the next closest unit to the closest unit, that is, the center point of the second closest unit is configured as 10 mm or more and less than 15 mm. In this case, a very high massage effect can be obtained.

In addition, in the washing brush 1 of the example shown to FIG. 1A, FIG. 1B, and FIG. 2, although the tuft hole 22 is comprised in one unit by arrange | positioning 4 holes in a square shape, it is not limited to this. For example, as shown in FIG. 5A, the hair-frilling hole 22 may be set as the unit arrange | positioned three-hole in an equilateral triangle shape, and as shown in FIG. 5B, the hair-frilling of five holes with one hole arrange | positioned at the center. It may be a unit consisting of holes 22. In addition, as shown in FIG. 5D, each of the units formed by the four-holes 22 arranged in the square shape in a square shape may be arranged at a shorter distance between centers on the woolen surface than in FIG. As shown in FIG. 5F, the configuration may be arranged at a long distance between centers. In addition, as shown in FIG. 5G, the tuft hole 22 may be a unit provided with two holes, and as shown in FIG. 5H, the tuft hole 22 has a total of six holes arranged in parallel by three holes. It may be set as a unit, and it can determine suitably.

`` Through hole ''

The scalp pore cleaning brush 1 of the present embodiment has a configuration in which at least one through-hole is provided so as to penetrate the base 2 at the substantially central portion and / or the peripheral edge of the seedling surface 21, and FIG. 1B. In the example shown in figure, the circular through-hole 21a is provided in the substantially center part of the seedling surface 21, and the arc-shaped notch parts 21b and 21c are formed in the peripheral part of the seedling surface 21, The through hole formed by the notches 21b and 21c and the opening 41 of the body 4 is formed.

As in the present embodiment, in the cleaning brush having a structure in which the base having the hair bundle contacting the scalp and the body having the gripping portion are combined, and the inside is hollow, the washing water, the cleaning agent, or the like is inside the fitting portion. When invading from the gap, these cleaning agents and the like are difficult to be discharged to the outside, so that there is a possibility that internal contamination or mold will occur, and it will be difficult to keep clean.

In such a case, for example, the base in which the hair bundle is planted is composed of a material that can be freely deformed, and the structure can be easily detached and detached from the body. It becomes possible to keep the inside clean. However, in the case of the cleaning brush in which the same bristle (hair bundle) as in the present invention is used, it is necessary to use a hard resin such as polypropylene as the material of the base to be planted, so that the base is not easily deformed, and desorption is difficult. Become. In addition, there is also a method of preventing the intrusion of the cleaning liquid or the like into the inside of the cleaning brush by completely sealing each bonding portion of the cleaning brush, but increasing the technical difficulty and increasing the manufacturing cost. Therefore, practical use as a product is difficult.

In this embodiment, at least one through-hole is provided in the outline central part and / or peripheral part of the seedling surface 21 so that the base 2 may penetrate, for example, a washing | cleaning liquid etc. invade from a joining part etc., for example. Even in this case, it can be easily discharged from the through hole and does not stay inside. This makes it possible to keep the cleaning brush clean at all times.

It is more preferable that the through holes provided to penetrate the base 2 are provided at two or more places on the seedling surface 21. As mentioned above, in the example shown to FIG. 1B, the through-holes 21a, 21b, 21c are provided in three places on the seeding surface 21, respectively.

By forming the through-hole at two or more places on the seedling surface 21, for example, when the inside of the cleaning brush 1, that is, the hollow portion 4a, is washed, the hollow portion 4a. It is easy to circulate the washing water in the).

Moreover, it is preferable that the ratio of the said through-hole to the total area of the seedling surface 21 is 3% or more and less than 20%.

If the ratio of the area of the through-hole to the total area of the seedling surface 21 is less than 3%, there is a possibility that the effect of discharging the cleaning agent or the like infiltrated into the hollow portion 4a may be lowered, and if it is 20% or more, There is a possibility that the hair transplantation site on the hair transplantation surface 21 becomes small, and the washing | cleaning effect of the scalp pores does not fully express.

In addition, in the example of illustration, as mentioned above, the circular through-hole 21a is provided in the substantially central part of the seeding surface 21, and the notch part 21b of circular arc shape is provided in the peripheral part of the seedling surface 21, 21c) is formed, and the through hole which consists of this notch part 21b, 21c and the opening part 41 of the body 4 is comprised, This is not limited, The shape, position, size, etc. of a through hole are suitably It is possible to decide.

As described above, according to the scalp pore cleaning brush 1 of the present embodiment, the tip portion 31a of the bristle 31 constituting the plurality of hair bundles 3 is roughly one plane on the seedling surface 21. In addition, since the hair growth area A in which the hair growth hole 22 is densely arranged and the hairless area B are arranged, respectively, a suitable sense of irritation is given to the scalp, the hair growth hole 22, That is, as compared with the case where the plurality of hair bundles 3 are evenly distributed on the base 2, a high massage effect can be obtained and a high scalp pore cleaning effect can be obtained. In addition, since the distal end portion 31a of the bristle 31 constituting the plurality of hair bundles 3 constitutes a substantially flat surface, only a specific bristle 31 is suppressed from coming into strong contact with the scalp, thereby damaging the scalp. We do not work and improve use feeling more.

In addition, in the scalp pore cleaning brush 1 of the present embodiment, the base 2 is integrally attached to the opening 41 of the body 4 formed in a hollow shape, and the outline center portion of the seedling surface 21 and / Alternatively, the through hole 21a (see also the notches 21b and 21c) is provided to penetrate the base 2 at the periphery, thereby penetrating the hollow portion 4a inside the cleaning brush 1. The washing water, the washing liquid and the like can be easily discharged. Therefore, the generation | occurrence | production of the scalp pore washing | cleaning brush 1 which can suppress generation | occurrence | production of a contamination and mold and can maintain a clean state can be implement | achieved.

[Scalp pores cleaning tool]

As shown in Figs. 6A and 6B, the scalp cleaning mechanism 10 of the present embodiment is provided with a scalp pore cleaning brush 1 according to the present invention, which is used to clean the pores of the scalp, A cleaning composition 50 having a viscosity at a liquid temperature of 25 ° C. of 15 Pa · s or more and less than 40 Pa · s is prepared in the scalp pore cleaning brush 1, forms an approximately one plane, and constitutes a plurality of hair bundles 3. It is used, being the structure supported by the front-end | tip part 31a of the bristle 31 to be used.

`` Cleaner composition ''

By supporting the cleaning composition 50 on the tip 31a or the end face 31b of the bristle 3, when the tip 31a of the bristle 31 enters the scalp pores, the inside of the pores more effectively. It becomes possible to remove the contamination.

(Support time)

As a specific support time of the cleaning composition 50, what is necessary is just to be able to support at the time which is inadequate practically, but as support time used as a reference | standard when a user performs a cleaning process, it is preferable to support at 10 second or more time. Do. If the supporting time is 10 seconds or more, when the tip portion 31a of the bristle 31 enters the scalp pores, the pores will enter the pores with the cleaning composition 50, so that the inside of the pores can be effectively cleaned.

(Viscosity)

In order to support the cleaning composition 50 to the bristle 31 at a time of 10 seconds or more, it is necessary to set the viscosity of the cleaning composition 50 to be in a range of 15 Pa · s or more and less than 40 Pa · s. It is preferable at the point obtained reliably, and it is more preferable to set it as the range of 18 Pa.s or more and less than 30 Pa.s.

If the viscosity of the cleaning composition 50 is less than 15 Pa.s, the cleaning composition 50 will not be supported by the tip portion 31a of the bristle 31 and will immediately flow down. Moreover, when the viscosity of the cleaning composition 50 is 40 Pa.s or more, when the cleaning brush 1 is inclined at the time of use, the cleaning composition 50 will be solid from the front end part 31a of the bristle 31. It will fall off as a gel-like thing, and it becomes difficult to support reliably also in this case. In addition, when the viscosity of the cleaning composition 50 is too high, the cleaning composition 50 is difficult to spread on the scalp surface, and thus, it becomes difficult to perform the cleaning process of uniformly foaming the entire scalp.

(Furtherance)

[Production of scalp pores cleaning brush]

In the following procedure, the hair-shape as shown in FIG. 3 was produced, and the sample of the scalp pore cleaning brush as shown in FIG. 1A and 1B was produced by attaching the base which the hair | bristle bundle was planted to the body. .

(Production of expectation)

First, as shown in FIG. 1A and FIG. 1B, it becomes a rough oval shape by the planar view of 79.3x64.3 mm, and the filamentary hole 22 of diameter 1.5mm is square on the base 2 of thickness 8.7mm. Four holes were arranged in each unit to make one unit, and a total of 18 units (total number of seedling holes: 72 holes) were arranged.
