Description

  The present invention is used together with a shampoo for washing hair and scalp, and has a high effect of removing dirt in and near the pores of the scalp, which has been difficult to wash conventionally, and at the same time, the hair is comfortably washed by massaging the scalp. More particularly, the present invention relates to a scalp pore cleaning brush excellent in maintainability, in which detached hair is less likely to be entangled with the brush and can be easily removed even when entangled.

Conventionally, various hair brushes used for washing hair are known. For example, one having a spherical body at the tip of the bristle (see Patent Document 1), a combination of a bristle having a spherical body and a bristle that does not have a spherical body (see Patent Document 2), and the outer circumferential surface in the length direction is a concave curved surface. One having a substantially conical bristle (see Patent Document 3), one having a small projection that flexes flexibly when the bristle tip touches the scalp (see Patent Document 4), and one having an open bristle tip (Patent Document) 5).
Although all of these conventional hair brushes have a massage effect on the scalp at the tip of the bristle when washing the hair, the bristle tip is thick, so the sebum discharged from the pores that cause dirt and odor on the scalp is removed and the pores are washed I couldn't.

  In addition, as a scalp / pore cleaning brush that combines a bristle with a thin tip and a large-diameter bristle, a bundle of small-diameter bristle with a diameter of 1 to 200 μm and insertion holes for a large-diameter bristle are alternately placed on the first substrate. Forming a resin-made large-diameter bristle having a diameter of about 1 to 5 mm on the second substrate, and inserting the large-diameter bristle of the second substrate into the insertion hole of the first substrate. A scalp and pore cleaning brush having a structure in which the above substrates are combined is known. (See Patent Document 6)

In addition, it has excellent combing by untangling hair, and it is based on a bristle with an elliptical cross section as a massage brush that can be used to clean not only hair and scalp but also pores, especially when used in combination with shampoos and hair restorers. A brush is known in which a plurality of bristles are arranged side by side on a table and a bundle of small diameter bristle is implanted between these bristles. (Patent Documents 7 and 8)
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 Japanese Patent Laid-Open No. 11-70019 JP 2000-60640 A JP 2000-139567 A

In these conventional cleaning brushes, the scalp massage effect is obtained because the large diameter bristle is implanted, but the tip of the large diameter bristle is larger than the pores, so it is hoped that the pore cleaning effect by the large diameter bristle is desired. In addition, the bristle with a narrow tip provided between the large-diameter bristle has a low flocking density, so it removes sebum from the pores that cause dirt and odor on the scalp, and has the ability to clean the pores. Was lacking.
In addition, these conventional cleaning brushes have a narrow interval between a hair bundle and a protrusion other than the hair bundle such as a hair bundle adjacent to the hair bundle or a large-diameter bristle, and the hair that has come off during washing is easily entangled and difficult to remove. It was not excellent for usability.

  In addition, in a cleaning brush having a conventional structure, it is considered that pores can be cleaned if a cleaning brush is configured by eliminating the large diameter bristles and densely planting only the narrow diameter bristles. However, the diameter of human hair varies depending on race, gender, age, presence / absence of combed hair, etc., but in general Japanese, it is about 40-100 μm and average is about 70 μm. The size of the pores that grow is considered to be equal to or greater than that, with an average of 70 μm or more. If a brush is constructed by closely planting a narrow bristle that has a diameter that fits into this size and enters the pores, even if you try to press the hair bundle of the brush against the hair root of the scalp during hair washing, Many other hairs tend to obstruct the progress of the narrow bristle, the thin bristle is easily bent, and the number of fine bristle can reach the pores is reduced, resulting in the desired pore cleaning effect. There is no problem.

  The present invention uses brush hair whose tip is thinner than the diameter of the pores to remove dirt such as lipids inside the pores, and is not easily disturbed by the hair covering the scalp. Provided is a scalp pore cleaning brush having an appropriate flocking pattern with excellent maintainability, in which the tip of the brush hair can easily reach the pores, and the loose hair is not easily entangled with the brush and can be easily removed even if entangled. It is for the purpose.

In order to achieve the above object, the present invention employs the following configuration.
(1) The scalp pore cleaning brush according to the present invention has a density in which the inside of the follicle hole on the base cannot be observed from the outside of the hair bundle in which one end of the shape is tapered and the hair is thinner than the diameter of the pore. In the scalp brush cleaning brush planted in step 1, the tips of the plurality of hair bundles constitute a substantially flat surface, and there is a gap between the tip of each hair bundle and the tip of the adjacent hair bundle. And the tips of the plurality of hair bundles form a discontinuous plane.
(2) In the scalp pore cleaning brush of the present invention, resin-made tapered hair having a diameter of 1 to 100 μm at one end is planted in the planting hole of the base so that the length is 5 to 30 mm. It is a scalp pore cleaning brush, and (A) the condition that the number of hairs to be implanted per hole is 10-50, and (B) the arrangement pattern of holes on the substrate, The condition that the distance between adjacent hair bundles or protrusions exceeds 2.5 mm and (C) the hole density of the substrate is ^{2 to} 15 per 1 cm ² of the planted hair area are satisfied. Features.

(3) The scalp pore cleaning brush of the present invention has, as an arrangement pattern of the flock holes on the base described in the above (2), a plurality of flock holes arranged on the basis of any one flock hole, The distance to the other flock hole with the closest distance, the distance to the other flock hole with the second closest distance, and the distance to the other flock hole with the third closest distance are all within 3-7 mm. It is characterized by.

  According to the present invention, since the tapered hair is implanted with a gap between the hair bundles, the hair can be reliably brushed by reaching the pores without being disturbed by the hair covering the scalp. It is possible to provide a scalp pore cleaning brush capable of cleaning pores and having good pore cleaning properties. Further, by providing a gap between the hair bundles, it is possible to provide a scalp pore cleaning brush that can easily remove entangled hairs even if the hairs get tangled.

According to the present invention, since the flocked hole on the base is implanted at a density that cannot be observed from the outside, the flocked hole is less likely to become dirty due to clogging with detergent or dirt, and the hair is entangled in the hair bundle. There is a difficult effect.
Furthermore, according to the present invention, since the resin-made tapered hair having a diameter of 1 to 100 μm at one end is used, the hair can be reliably inserted into the pores, and the pore cleaning effect can be exhibited. . Further, since the hair is implanted so as to have a length of 5 to 30 mm, the hair tip can be surely reached by avoiding the hair of the scalp, so that there is an effect that the pore cleaning can be surely performed.
Next, as the hair transplantation pattern, the hair covering the scalp when brushing the scalp, since the number of hair transplants is 10 to 50, the hole spacing exceeds 2.5 mm, and the hole density is ^{2 to} 15 per 1 cm ^{2 of the} hair transplant area. As a result, it is possible to provide a scalp pore cleaning brush that can reach the pores while passing through the hair while avoiding interference with the hair as much as possible, can reliably clean the pores, and is less likely to damage the pores.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below.
FIG. 1 shows the structure of a scalp pore cleaning brush according to a first embodiment of the present invention. The scalp pore cleaning brush A of this embodiment is one side of a disk-shaped base 1 (the upper surface side in FIG. 1). A plurality of flocks are applied, and a post-shaped handle portion 2 and a knob-type grip portion 3 are formed on one surface on the opposite side of the base 1 so as to be located in the center portion.
In the present embodiment, for example, 10 to 50 hairs 5 are implanted in the flock holes 4 formed on the one surface side of the base 1 at predetermined intervals. The bristle 5 is a bundle 6 and protrudes outside the base 1 from 5 to 30 mm in hair length, for example, and the gap between the hair bundle 6 and another adjacent hair bundle 6 is, for example, The gap exceeds 2.5 mm. Further, the hair bundle 6 is planted at such a density that the inside of the planted hole on the base 1 cannot be observed from the outside.
The reason why the size and shape of each part are prescribed in the scalp pore cleaning brush A of the present embodiment will be described below.

-Hair length 5-5 mm:
When the hair length of the hair 5 is shorter than 5 mm, the hair is in the way and it is difficult for the hair 5 to reach the background and pores. When the hair length is longer than 30 mm, the hair 5 is easily bent and difficult to reach the background and pores. Although the flocked hair length may vary somewhat, it is preferable in terms of quality that 90% of the flocked hair falls within the range of 5 to 30 mm.

-Flocking pattern condition of hair 5 (A): Number of hairs 5 of hair 5 per hole: Density in a state where the inside of the hole cannot be observed from outside: More specifically, Number of hairs 5 of hair 5 per hole 10 ~ 50:
If the number of flocks of the hair 5 per hole is so small that the inside of the hole can be observed from the outside, it is not preferable because the hair that has fallen into the hair bundle is easily entangled and difficult to remove. In addition, it is not preferable in terms of hygiene of the cleaning brush A because the flocking hole is likely to be clogged with a cleaning agent or a rinse agent used at the time of shampooing. On the other hand, in the case of the cleaning brush of the present invention in which the number of hairs inside the hole is not observable from the outside, the hair that has come out in the hair bundle does not get entangled and there is no gap in the hair hole so that the cleaning agent is clogged. Hateful.
If the number of flocks is small relative to the cross-sectional area of the pores, a slight gap occurs between the hairs and the hair, and although there are individual differences, hair with a diameter of approximately 70 μm is sandwiched between the slight gaps, It is extremely difficult to remove and becomes in a defective state.
As a reference example, if the hair 5 has a diameter of 190 μm with respect to a flocking hole having a diameter of 1.5 mm, 21 hairs are connected by a flat wire having a thickness of 0.25 mm to the center of the hair. When the hair is fixed and fixed, the inside of the hair cannot be observed from the outside. Considering this state in terms of the cross-sectional area, the cross-sectional area occupied by the bristles is 0.095 × 0,0, compared to 0.75 × 0.75 × 3.14 = 1.77 square mm, which is the cross-sectional area of the flock hole. 095 × 3.14 × 21 × 2 = 1.19 square mm, and 67% of the cross-sectional area of the flocked hole is occupied by the hair.

When 21 hairs 190 μm in diameter are embedded in a 1.77 mm ² flocking hole, if 67%, it is in a state that cannot be observed, but by implanting 13 hairs, it becomes 42% of the boundary of the unobservable state, When the boundary is less than 42%, a hole is formed so that the hole can be observed from the outside, and hair having a diameter of 70 μm is easily entangled.
From the viewpoint of easy entanglement of the hair, if it falls below the previous boundary of 42%, the hair is easily entangled. For this reason, the range of 42% or more and 85% or less is preferable. In addition, if the proportion of the hair is more than 85%, the flocked hole is likely to break and the flocked hair opens, which is not preferable.

If the number of flocks to the flock holes 4 is less than 10, the effect of cleaning the pores is poor, and if the number of flocks is more than 50, it is necessary to open a large flock hole on the base 1, so use it in the flock holes when washing the hair. Cleaning agents, rinse agents and the like are easily clogged, which is not preferable in terms of hygiene of the cleaning brush A. In some cases, the number of flocks may vary, but it is preferable in terms of quality that 90% of the flocked holes are in the range of 10 to 50.
If the hair bundle 6 is densely arranged on the base 1 without a gap, the hair surface on the scalp becomes a physical obstacle and the hair 5 is bent in the hair washing action for washing the scalp and pores. This is not preferable because the tip of the hair 5 is difficult to reach the scalp and pores. For this reason, since the hair 5 of the hair bundle 6 passes through between the hair on the scalp without trouble, and as much hair 5 as possible reaches the pore portion and its surroundings, The number of the hairs 5 and the interval between the adjacent hair bundles 6 are important.

In the brush A of the present embodiment, the hair bundle 6 composed of the 10 to 50 hairs 5 described above is arranged at a predetermined interval so that adjacent hair bundles 6 are not in contact with each other or are not excessively close to each other. ing.
-Flocking pattern condition (B) of the hair 5: The distance D between the hair bundle 6 and another adjacent hair bundle 6 or other protrusion exceeds 2.5 mm:
When the distance D between the hair bundles 6 is within 2.5 mm, the hairs are easily entangled and difficult to remove. Although there is no restriction in particular when the space | interval D of the hair | bristle bundle 6 is wider than 2.5 mm, when the hole density becomes low as shown to the following (C), the density of the hair 5 will become too sparse and the washing | cleaning effect of a pore Become inferior.
In addition, it is preferable to set it as the space | interval D exceeding 2.5 mm, and by arrange | positioning the hair | bristle bundle 6 which consists of 10-50 hair 5 with the space | interval D exceeding 2.5 mm, several hair bundle group This is because the hair is difficult to be entangled with the hair 6, and even if the hair is entangled between the hair bundles 6, the structure can be easily removed.

  The spacing will be described below by taking as an example a case where one missing human hair is entangled between the hair bundles 6 having a diameter of 190 μm and a tip diameter of 20 μm made of polyethylene terephthalate. When observing the state where the human hair and the hair 5 of the present embodiment are wet with tap water, water droplets having a maximum diameter of 1.5 mm are present on one human hair, and the hair 5 of the brush A has a diameter of 1 maximum. 0.0 mm water droplets adhere. That is, an interval D of 0.5 mm, which is a total value of 0.5 mm, which is a radius of a water droplet from the end of the hair bundle 6 of the brush A, and a diameter of 1.5 mm, which is attached to human hair, has a human hair and a hair to be used Reference numeral 5 denotes an interval between borders in contact with water droplets having the maximum diameter. If the distance D between the hair bundles 6 of the brush A is narrower than that, human hairs will come into contact with the hair bundle 6 of the brush A at two locations via the surface tension of water and cannot be easily removed. However, if the distance D is wider than 2.5 mm, the human hair comes into contact with the bristle bundle 6 of the brush at one point, so that removal is easy. At the same time, this means that the hair is less likely to get entangled with the hair 5 of the hair bundle 6 when using the hair. Further, this is not limited to the interval between the hair bundle 6 and the hair bundle 6, and the same can be said for other protrusions on the base 1 adjacent to the hair bundle 6.

-Flocking pattern condition (C): The hole density of the flocked holes is ^{2 to} 15 per 1 cm2 of the base flocked area:
If the hole density of the flocked holes is less than 2, the cleaning effect of the pores is inferior. If it is more than 15, the density is too high and the hair is difficult to reach the ground. In addition, the flocked area of the base on which this calculation is based indicates not the area of the base itself but the area of the part surrounded by the outermost periphery of the flocked part of the base.
Further, as an arrangement pattern of the flock holes 4 on the base 1, among the flock holes 4 arranged in the base 1, another flock hole 4 having the closest distance with respect to any one flock hole 4. It is desirable that the distance to the other flocked hole 4 with the second closest distance and the distance to the other flocked hole 4 with the third closest distance are all within a range of 3 to 7 mm.

As an example of the bristles 5, in the present embodiment, as shown in FIG. 3, a necessary number (about 5 to 25) of filaments having tapered portions 5a at both ends are bent in a U-shape, and these bent portions are used as bases. The structure formed by pushing into one flocking hole 4 and flocking can be employed. The hair length of the hair 5 protruding from the surface of the base 1 in the planted state is within the above range.
In addition, the hair transplantation method will not be restrict | limited especially if the hair transplantation pattern shown on the following conditions is satisfy | filled. For example, the method of fixing the bristles in the hole of the substrate with a flat metal wire such as Japanese Patent Application Laid-Open No. 2001-309818, the invention of the present applicant, or Japanese Patent Application Laid-Open No. 10-42956, Japanese Patent Application Laid-Open No. 10-52317, etc. A method of fusing or bonding without using metal is possible.

The filament constituting the bristles 5 is made of a synthetic resin described later, and tapered portions 5a are formed at both ends thereof. These filaments are 25 to 35%, 55 to 70% of the diameter of the central part of the filaments where the hair diameter at each part of 1 mm, 3 mm, 5 mm, and 8 mm from the tip of the taper part 5a does not form a taper, 80 to 90% and 90 to 100%. Here, considering the cleaning of the pores of the user's scalp, it is desirable that the diameter of the tip of the tapered portion 5a be in the range of 1 to 100 μm.
The filaments constituting the plurality of hairs 5 planted on the base 1 have hairs corresponding to the protruding length from the base 1 by aligning the positions of the tips 5a within a range of about ± 2 mm. It is planted with the same length. In addition, when a filament is planted so that the level exceeds the range of ± 2 mm, for example, a long hair length and a short hair length so that the step exceeds 2 mm, the long hair length filament reaches the pores. Since the filament having a length does not reach the pores, the cleaning effect of the pores may be reduced.

Although there is no restriction | limiting in particular in the material which comprises the filament which comprises the hair 5 of this embodiment, Polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) which are general resin materials Use of nylon, polyester, etc. is suitable. In addition, for example, for the purpose of improving aesthetics as described in JP-A-11-253236, for example, a material mainly composed of synthetic resin mixed with other components, or for adding an antibacterial agent or the like to improve durability Hair can also be used.
In the case of hard materials such as metal, strength can be secured even if it is thin, so it is possible to use straight hair instead of taper shape, but if it is broken during use, the shape of the cut surface is sharp This is unfavorable in terms of safety because it hurts the skin during massage.
There is no restriction | limiting about the method of processing the filament which comprises the hair 5 in a taper shape. Using straight-filament filaments, the tip can be processed into a tapered shape by dissolving the resin using chemical methods such as chemicals, or by grinding around the tip of straight-hair-shaped hair with mechanical force It is also possible to process into a taper shape.
In addition, since the filaments constituting each hair 5 have a tapered shape at each tip 5a, even if the force on the scalp hits the hair on the scalp, the gap between the hairs is reduced. It can be bent to avoid reaching the pores of the scalp.
Tapered hairs have thin tips, and if washed with a strong force, the tips will bend and it will be difficult to remove dirt from the pores. It is preferable to apply a weight of about 300 g to 1000 g from the hand to the brush for cleaning.

On the other hand, there is no restriction | limiting in particular in the size and shape of the flock hole of the base 1, What is necessary is just the size of the flock hole required in order to plant 10-50 hair per hole. In addition, the shape of the flock hole is generally circular. However, as shown in, for example, Japanese Patent Laid-Open No. 2000-50955, a non-circular flock hole may be used for the purpose of improving quality and improving manufacturing efficiency. Is possible.
An intermediate product after flocking usually becomes a product by attaching a handle etc. to the base after flocking and packaging it. For example, as shown in JP-A-2001-46149, the quality of the brush after flocking is improved. For example, a method of performing some other treatment such as cooling and heat-treating the intermediate product after flocking is possible without departing from the scope of the present invention.
About a hair transplanter, the scalp washing brush of this invention can be manufactured by diverting the machine which manufactures a toothbrush generally, and there is no restriction | limiting in particular in the form of the manufacturing apparatus to be used. For example, the manufacturing apparatus described in JP-A-2000-93233 can be used.

<Method of manufacturing scalp cleaning brush>
The pattern shown in FIG. 2 is such that a flocked hole having a diameter of about 1.5 mm is formed on a circular substrate (base) made of polypropylene having a diameter of 8 cm and a thickness of 0.7 cm, and the distance between the hair bundles is 4 mm. It arranged as follows.
The total number of flocked holes is 216, and the hole density is about 4.3 / cm ² . Cut the original yarn with a hair diameter of 190 μm using PBT: PET = 7: 3 as a mixed resin, and after chemical processing (immersion in a heated high-concentration NaCl solution), taper both ends to taper hair Got.
The diameter of the hair tip was 30 μm. A scrubbing pore cleaning brush according to the present invention was obtained by implanting 21 hairs per hole into a flocked hole on a circular substrate surface with a normal flat-type flocking machine.
The hair length, which is the length from the substrate surface to the hair tip, was in the range of 12 mm ± 0.5 mm on average.
Next, as a scalp pore cleaning brush of Comparative Example 1, it is a brush in which a hair bundle 16 made of hair 15 is implanted in the hair implantation hole 14 of the substrate 11, and the intervals between the hair bundle 16 and the hair bundle 16 are all 2. A brush having the pattern of FIGS. 5 and 6 consisting of 0 mm was prepared. In the brush of this example, the total number of flock holes is 916, and the hole density is about 18 / cm ² . The hair, the method of flocking, and the number of flocks per hole are the same as the pattern of FIG.
Further, as a scalp pore cleaning brush of Comparative Example 2, a straight hair which is not a taper hair having a hair diameter of 150 μm and a tip diameter of 150 μm using nylon is the same flat hair transplanter as in the previous example. Then, 216 hairs were planted in the same 1.5 mm planting hole as in the previous example.

<How to use scalp cleaning brush>
On the scalp pore cleaning brush obtained as described above, sodium polyoxyethylene lauryl ether sulfate is the main surfactant, and gel-like transparent hair having a viscosity measured at 25 ° C. of 20 Pa · s. -About 10 g of the shampoo composition for the background was applied, and the wet hair and the background were washed with foaming by moving the whole hair and the background uniformly for about 3 minutes with this brush. After that, like normal shampoo behavior, the hair was rinsed with hot water and the hair was dried. The test subjects used 5 male panels whose hair length was a little over the ears and no wrinkles were observed.

<Evaluation method of cleaning effect>
After washing, the hair was shaved with scissors in the range of 1 cm × 1 cm to make it easy to observe the pores. With a USB microscope M2 (manufactured by scalar), the state of pores was observed by magnifying 200 times and evaluated according to the following evaluation criteria.
