Description

TECHNICAL FIELD The present invention relates to a hair finishing comb suitable for hairdressing and cosmetology that cleans and beautifully arranges hair, and a combing method that allows hair to be cleanly and beautifully arranged using the comb. More specifically, it has the effect of removing excess sebum adhering to the hair and scalp, preventing hair loss and promoting hair growth, as well as giving gloss and body to the hair, correcting curly hair, and adding volume. This invention relates to a hair finishing comb suitable for hairdressing and beauty care, which has the effect of making hair smooth and silky, and a combing method suitable for hairdressing and beauty care using the comb.

Regardless of gender, there is a strong desire to have clean and well-groomed hair. In particular, in the case of women, there is a wide demand for smooth, shiny, and beautiful hair without frizzy hair, regardless of age, and it cannot be said that the expenditure on hairdressing is low. This can be seen from the 2016 expanded survey results of the Ministry of Internal Affairs and Communications Statistics Bureau's ``Service Industry Trend Survey,'' which shows that the hairdressing market, which includes the barber industry and the beauty industry, is approximately 2.7 trillion yen. It is understood from this (Non-Patent Document 1).

In response to this demand, we are developing technology that removes sebum, scalp dandruff, and other waste products that adhere to the hair and scalp, as well as oil-based hair styling products to keep the hair clean and prevent hair loss. BACKGROUND ART Various techniques have been studied for a long time to add luster and body to hair, to straighten curly hair, and to make hair smooth and voluminous.

A common method to remove the above-mentioned oil components attached to the hair and scalp, keep the hair clean, and prevent hair loss is hair washing (scalp cleaning) that also serves as a massage. The use of cleansing oil and carbonated water are also recommended. In addition, in order to suppress the production of excess sebum, people are changing their lifestyle by reducing their intake of oil-rich foods and taking more vitamins. However, the scalp has the most sebaceous glands in the human body, about three times as many as the face, and the pores are large and numerous, so waste products such as sebum and dandruff and oil components such as oily hair products accumulate. Easy to fall off. Therefore, cleaning devices and cleaning instruments have been devised to suit various situations.

Cleaning devices that are thought to have been devised for commercial use include those that suck and remove oil and fat components attached to hair, pores, etc., and those that remove them by rinsing them out. As for the former, it is proposed that a suction nozzle having a head tube equipped with a protruding tube made of an elastic body is connected to the suction port of a vacuum pump via a hose, and the vacuum pump removes the pore-cleaning oil and fat that is abundant in the pores of the armpits. It is described that it can also be used to deal with sebum that is abundant on the scalp (Patent Document 1 and Non-Patent Document 4). For the latter, while rotating protrusions are brought into contact with the scalp, fine droplets of charged water and fine powder of special metals such as copper and silver are sprayed from the protrusions to cleanse the scalp and provide antioxidant protection. A scalp care device (Patent Document 2) that can provide anti-bacterial effects, antibacterial effects, etc., and an airbrush that uses compressed gas to spray cosmetics for treating the scalp, such as removing dandruff, preventing hair loss, regenerating hair, and preventing seborrhea, onto the scalp. A cleaning device (Patent Document 3) and the like that can perform cosmetic treatments have been proposed. However, these devices require complicated and expensive equipment such as vacuum pumps, electrostatic atomizers, metal atomizers, rotary drive sources, and compressors, so they are difficult to handle even for commercial use. , treating the scalp requires special substances such as charged water droplets, metal powders, chemicals, etc. to violently impinge on the scalp, which can have adverse physical or chemical effects on the scalp.

On the other hand, when washing hair by applying shampoo and rubbing the hair and scalp with your fingers, the more you massage and rub the hair, the more oil and fat components can be removed, but it may damage the hair cuticle or damage the scalp. To avoid damage, an electric scalp hair washer is equipped with a brush-shaped handle that has a drive source and a drive member, and a head that has triangular teeth arranged in parallel that are chewed by the drive source and the drive member. It has been proposed (Patent Document 4). It is stated that since the hair is washed by the chewing motion of the triangular teeth, oil and fat components attached to the hair and pores can be removed without damaging the hair or damaging the scalp.

As a simpler cleaning tool, it is originally a tool for untangling and conditioning hair, but by brushing or combing the hair, it has the effect of removing sebum, dandruff, etc. attached to the scalp and hair. Improvements have been made to certain hair brushes or combs.

In the case of hairbrushes, various bristle structures and shapes have been proposed with the aim of solving the problem that the hairbrush bristles do not reach the pores of the scalp. For example, by equipping the seat of the brush with two types of comb teeth, long and short, with a tuft of hair at the tip of the short comb teeth, the long comb teeth can separate the hair, and the short comb teeth can separate the hair. A brush with bundles that makes it easy to remove sebum, dandruff, etc. attached to the scalp (Patent Document 5), a brush with tapered hair bundles that are thinner than the pores implanted in the seat (Patent Document 6), and A brush (Patent Document 7) has been disclosed that has a plurality of planar projections formed of nonwoven fabric instead of bristles.

On the other hand, in the case of a comb, since the tips of the teeth do not reach the pores of the scalp, a comb has been proposed that has a light source containing ultraviolet rays inside the teeth coated with a photocatalyst (Patent Document 8). It is stated that the oxidizing action of the photocatalyst irradiated with ultraviolet rays decomposes oil and fat components adhering to hair, pores, etc. into hydrophilic substances, which can be removed with a small amount of water without washing the hair.

Furthermore, focusing on the material of the comb, we have developed a comb made of paper that easily absorbs oil and fat components (Patent Document 9), and a comb that is similarly manufactured using a resin molding method using pulp that easily absorbs oil and fat components (Patent Document 9). Document 10) is disclosed. These can be said to be the simplest methods that can remove oil and fat components simply by combing the hair without washing the hair.

As mentioned above, various cleaning devices and cleaning tools have been devised to remove waste products such as sebum and dandruff, as well as oil and fat components such as oil-based hair styling products. It can be said that the method for removing the components is a simple cleaning tool and cleaning method that does not damage the hair and scalp and does not require washing the hair. However, these cleaning tools and cleaning methods do not have the ability to straighten curly hair.

Regarding techniques for straightening curly hair and making hair smooth and voluminous, many methods have been proposed that use a curling iron and permanent chemicals in combination, which is a reverse application of iron perm that curls straight hair (Patent Document 11 , 13, 15, and 16). However, since it is a two-bath permanent agent that not only applies heat to the hair but also applies a first agent (reducing agent) and a second agent (oxidizing agent) as permanent agents, it can damage not only the hair but also the scalp. There were problems in that the corrective force and holding force were insufficient. Therefore, improvements have been made to the first permanent drug (Patent Document 13) and the application of one-bath permanent drugs (Patent Document 16). In addition, in the case of hair irons, the hair is strongly pinched between the uneven ironing surfaces, and the hair may be handled from the root to the tip. Even if the curling iron is applied, the damage to the hair is great, so a technique has been proposed in which a flexible shaping jig with a built-in heat source is used as a hair iron (Patent Document 15).

On the other hand, as a method for straightening curly hair without using permanent chemicals, brushing with a twin brush whose handles are connected by a hinge so that the bristles of the two brushes face each other has been used for a long time (Patent Document 12). However, there are problems with the straightening power and its holding power, and a method using a permanent agent (Patent Document 14) and a method using a twin brush and a hair iron in combination (Non-Patent Document 5) have been proposed.

However, in recent years, a method using electrolyzed water has been proposed as a straightening method that does not use permanent chemicals and does not damage the hair and scalp (Patent Document 17). In this method, alkaline electrolyzed water is sprayed onto the hair using an air brush or air spray connected to a compressed gas, and then acidic electrolyzed water is sprayed onto the hair. Even if curly hair can be straightened by this method, there is no mention of the effect of removing waste products such as sebum and dandruff stuck in hair and pores, and oil components such as oily hair styling products. Also, like washing hair, an electrolysis device is required and a large amount of water is required.

Furthermore, a hair orientation device (comb) and a hair orientation method using the comb have been disclosed (Patent Document 18). Since no permanent chemicals or heat are used, there is no damage to the hair or scalp, and it is possible to direct the hair in a neutral state in a predetermined direction, as well as remove sebum, etc. accumulated in the pores. It is stated that this is possible. However, this method of directing hair using a comb involves pressing the small contact area at the tip of the comb against the hair near the scalp, and then moving the comb along the shape of the head. Since the hair is oriented by moving it in a predetermined direction, it is easily assumed that the hair and scalp will be damaged. Furthermore, there is no description that this method produces an effect of straightening curly hair, and no element is found to produce it. In addition, regarding the removal of sebum etc. by this method, the thickness of the contact part of this comb is approximately 2 mm, and it is formed in an arc shape toward the tip, so the size is close to that of a pore (i.e., approximately 0 in diameter). It is stated that it is possible to remove sebum etc. accumulated in the pores because the contact part of Non-Patent Documents 6 and 7) is brought into contact with the hair and moved while pressing the hair against the scalp. It is considered that there is a risk of damaging hair and scalp. In addition, skill is required to bring the small-area contact portion into contact with the hair and press it against the scalp.

In this way, it removes sebum, dandruff, and other waste products and oil-based hair products that adhere to the hair and scalp without using water, hair wash, permanent chemicals, heat, etc., and without damaging the hair or scalp. No technology has been found that can keep hair clean and prevent hair loss, add gloss and body to hair, correct curly hair, and make hair smooth and voluminous.

The present invention removes sebum, dandruff, and other waste products and oil-based hair styling products that adhere to the hair and scalp without using water, hair wash, permanent chemicals, heat, etc., and without damaging the hair and scalp. The purpose of this invention is to provide a technology that keeps hair clean and prevents hair loss, as well as a technology that can add luster and body to hair, correct curly hair, and make hair smooth and voluminous. do.

The inventor focused on conventional brushes and combs, as well as interesting features and phenomena of brushing and combing, and conducted various studies on the shape, material, form/configuration of combs, and combing methods. As a result, a comb with a mirrored surface, a comb made of a magnetic iron-based alloy, a comb with a mirrored surface and made of a magnetic iron-based alloy, a body, a comb tip ( A comb that integrally includes a comb, a comb body, a handle, and a thumb hole, or a comb that integrally includes a body, a comb tip, a comb body, a handle, and a thumb hole. A comb main body, a comb operation auxiliary body integrally equipped with a movable handle, a ring finger hole, and a little finger rest are connected to each other by a pivot in the center of the comb body. Cleans the hair by removing sebum, dandruff, and other waste products from the hair and scalp, as well as oil-based hair conditioners, without using hair washes, permanent chemicals, heat, etc., and without damaging the hair or scalp. They found that it has the effect of keeping hair shiny and firm, correcting curly hair, and making hair smooth and voluminous, and also found that the effect can be enhanced by combing. The present invention has now been completed.

First, the comb of the present invention includes at least integrally a body supporting a plurality of teeth, and a plurality of teeth vertically disposed in a line at a predetermined interval on the body, and includes at least a body and a plurality of teeth. The surface roughness of the upper and lower surfaces of the barrel and the teeth located in the vertical direction of the barrel, as well as the side surfaces of the barrel located in the opposite direction from the tips of the teeth, is 0.100 μm or less, based on surface roughness measurements. This comb is characterized by roughness (Sa). Such a mirror surface can be formed by various polishing methods, but it is preferable that Sa is as small as possible, and it is more preferable that Sa is 0.070 μm or less. Alternatively, the comb may have a surface texture that satisfies a maximum height (Sz) measured by surface roughness measurement of 1.60 μm or less, more preferably 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz has a kurtosis (Sku) measured by surface roughness of 12,000 or less.

By using such a comb, you can remove sebum, dandruff, and other waste products that adhere to your hair and scalp, keep your hair clean, and keep your hair clean by adding luster and body to your hair. The effect of correcting hair loss and making hair smooth and voluminous was clearly recognized. In contrast, no such effect was observed when the same part of the comb was not polished.

Although the scientific basis of this experimental result is unknown, the upper and lower surfaces of the trunk and the plurality of teeth are vertically located, and the upper and lower surfaces of the trunk and the plurality of teeth are at least in contact with the hair and the scalp when combing the hair with a comb. In addition, by mirror-finishing the sides of the body located in the opposite direction from the tips of the multiple teeth, the contact area with the hair and scalp increases compared to a comb in which these parts are not polished. We hypothesize that increased interaction with the scalp may be associated with an increased amount of static electricity in the hair and scalp that accumulates due to contact, friction, and abrasion.

This hypothesis is based on experimental results that the combing effect is improved by reducing the surface roughness of the comb's surface texture until Sa is 0.100 μm or less and Sz is 1.00 μm or less. In addition to being supported by the comb, the combing effect is improved by reducing the surface sharpness of the surface texture of the comb until Sa is 0.100 μm or less and Sku is 7.000 or less. This is also supported by experimental results.

Therefore, the above effects are gradually enhanced by increasing the shape and structure of the comb, especially by increasing the number of parts of the comb that come into contact with the hair and scalp. The comb is provided with at least a body supporting a plurality of teeth, and a plurality of teeth hanging from the body in a row at predetermined intervals. Comb cusps formed at predetermined intervals on the distal teeth of the plurality of teeth are provided through the shoulder, and at least the upper and lower surfaces located in the vertical direction of the comb cusps and in the direction of the tips of the comb cusps are provided. The surface shape of the side surface is preferably 0.100 μm or less, more preferably 0.070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

Furthermore, at least a body supporting a plurality of teeth, a plurality of teeth hanging in a row on the body at predetermined intervals, and a shoulder extending from the body at the tip of the body, The comb integrally includes comb tips formed at predetermined intervals on the teeth at the tips of the teeth, and a comb body extending from the body and the plurality of teeth in a direction opposite to the comb tips, It is preferable that at least the surface texture of the upper surface and lower surface located in the vertical direction of the comb body, and the side surface of the comb body located in the opposite direction from the tips of the plurality of teeth is Sa of 0.100 μm or less, and 0. More preferably, the Sa is .070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

In addition, the surface of the comb that does not come into contact with the scalp but does come into contact with the hair has a side surface where a plurality of teeth face each other, and the surface texture of this side surface is preferably Sa of 0.100 μm or less. More preferably, Sa is 0.070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

For such polishing of the comb surface, general mechanical polishing, electrolytic polishing, and chemical polishing can be used. Regardless of the material used, mechanical polishing is preferred, and buffing is particularly preferred, in order to produce a mirror-like luster.

When buffing is applied to the final finish, it is preferable to perform preliminary polishing with sandpaper or the like in advance. Furthermore, for the final buffing, it is preferable to use an iron buff for rough finishing, a blue buff for intermediate finishing, and a white buff for finishing, but the method is not limited thereto. This intermediate finishing using the blue buff and finishing using the white buff are important steps in developing the surface quality of the present invention. In addition, as the blue buff, it is preferable to use loose buff made of cotton fabric sewn only around the hole into which the shaft of the grinder is inserted, and as the white buff, it is preferable to use loose buff made of cotton fabric or calico. In addition, abrasives can be Tripoli-based, alumina-based, blue rod-based, green lime-based, resin-based, grease rod-based, etc., but for final finishing, chromium oxide-based blue rod, alumina oxide-based white rod, Preferred are alumina oxide-based non-chromium, resin-based non-chromium, and the like.

However, there is a problem in that applying mechanical polishing to polishing the side surfaces where a plurality of teeth face each other requires a great deal of labor. In the case of metal materials such as stainless steel, it is possible to apply electrolytic polishing and chemical polishing, but in the case of electrolytic polishing, it is difficult to provide a counter electrode, so as with chemical polishing, it is difficult to achieve the desired surface roughness. There are some materials in which it is difficult to form combs, so the materials for the comb are limited. Iron-based alloys, particularly carbon steel, special steel, and stainless steel are more preferred, and stainless steel is even more preferred. In electrolytic polishing, when a counter electrode is provided in a space where a plurality of teeth face each other, the cost of electrolytic polishing increases, but the desired surface roughness can be applied to a wide range of metal materials. Further, in the case of a comb made of a metallic material, it is preferable to use electrolytic polishing, chemical polishing, and mechanical polishing in combination.

As described above, there are problems with polishing the sides where multiple teeth face each other, so we conducted an experiment using a comb that does not polish the sides where multiple teeth face each other. And if the Sa of the outer circumferential part of the comb that comes into contact with the scalp, excluding the side surface where the plurality of teeth face, is at least 0.100 μm or less, sebum attached to the hair and scalp, waste products such as dandruff, oily hair styling products, etc. It has been clearly recognized that it is effective in removing hair, keeping it clean, adding luster and body to the hair, correcting curly hair, and making hair smooth and voluminous. It is not necessary to polish the side surfaces facing each other.

Secondly, the comb of the present invention is a comb that includes at least a body that supports a plurality of teeth and a plurality of teeth that are vertically disposed in a line at predetermined intervals on the body, and the comb is made of C. Content: 0.80% or more and 1.35% or less, Si content: 0.25% or less, Mn content: 0.35% or less, P content: 0.03% or less, S content: 0. Carbon steel having a chemical composition of 0.006% or less, Ni content: 1.30% or less, Cr content: 0.50% or less, C content: 1.00% or more and 1.50% or less, Si content: 0.30% or less, Mn content: 0.30% or less, P content: 0.025% or less, S content: 0.02% or less, Cr content: 0.15% or more and 0.50% or less , special steel having a chemical composition of V content: 0.50% or less, W content: 2.50% or less, and C content: 3.00% or less, Si content: 1.00% or less, Mn content: 1.00% or less, P content: 0.04% or less, S content: 0.03% or less, Ni content: 0.49% or less, Cr content: 4.50% or more20 .0% or less, Mo content: 5.00% or less, V content: 3.00% or less, W content: 6.00% or less, Co content: 8.00% or less. A comb characterized by at least one selected from the following.

By using such a special iron-based alloy as the material of the comb, it removes waste products such as sebum and dandruff that adhere to the hair and scalp, as well as oil-based hair styling products, and keeps the hair clean. The effect of adding luster and body to hair, straightening curly hair, and making hair smooth and voluminous was clearly recognized. Since such materials have magnetism, such an effect could not be observed with non-magnetic combs made of plastic, for example.

The scientific basis for this experimental result is also unknown, but just as magnetism is effective in relieving stiff shoulders and headaches, the earth's magnetic field interacts with the comb made of magnetic material, and the magnetic comb It is speculated that repeated contact with the hair and scalp, friction, and peeling may have some effect on the hair and scalp.

Therefore, as well as the surface roughness, the shape and structure of the comb are also affected, and the comb body includes at least a body that supports the plurality of teeth, and a plurality of teeth that are vertically disposed in a line at predetermined intervals on the body. Furthermore, such a body, The above effects can be further enhanced by at least integrally providing a comb body having a plurality of teeth, shoulders, and comb tips with a comb body extending from the body and the plurality of teeth in the opposite direction of the comb tips. It was recognized that it could be improved. Moreover, the surface texture of each part of the comb is preferably Sa of 0.100 μm or less, more preferably Sa of 0.070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

Thirdly, the comb of the present invention has a body that supports a plurality of teeth, a plurality of teeth that are vertically disposed in a line at predetermined intervals on the body, and a comb that is located at the tip of the body and extends to the body. A comb tip formed on the tip of the plurality of teeth at a predetermined interval through the shoulder, a comb body extending from the body and the plurality of teeth in a direction opposite to the comb tip, and a comb body extending from the body to the comb body. The comb is characterized in that it is at least integrally equipped with a handle provided thereon.

A comb having such a body, a plurality of teeth, shoulders, comb tips, and a comb body is at least integrally provided with a handle that extends to the comb body, so that the upper surface of the comb is directed upward, and the comb is It plays an important role in performing combing, which involves moving the back in parallel and reciprocating directions in all directions along the scalp, with or without contact with the scalp. In particular, it is preferable that this handle extends in an inclined manner in the same direction as the tips of the plurality of teeth, and it is easier to operate the handle if a thumb hole is formed at the rear end of the handle. As a result, regardless of the surface roughness and material of the comb, it is possible to impart luster and stiffness to the hair, correct curly hair, and make the hair smooth and voluminous.

Further, a body supporting a plurality of teeth, a plurality of teeth hanging down in a row from the body at predetermined intervals, and a shoulder extending from the body at the tip of the body, the body supporting a plurality of teeth. A comb tip formed on the tips of the teeth at predetermined intervals, a comb body extending from the body and the plurality of teeth in the opposite direction of the comb tip, and a tooth tip of the plurality of teeth on the comb body. The comb main body is a comb integrally equipped with a handle that extends in the same direction as the handle, and a thumb hole formed at the rear end of the handle, and this comb body, a moving handle, and one end of the moving handle. The other end of the comb operation auxiliary body, which is integrally equipped with a ring finger hole and a little finger rest formed in the comb body, is pivoted at a predetermined angle of rotation by a pivot that spans a shaft at approximately the center of the comb body. The tied comb can be handled in the same way as scissors using the thumb, ring finger, and little finger, and the back of the comb from the body to the comb body can be used to run the comb vertically and horizontally along the scalp, with or without contacting the scalp. This is an extremely preferable form and configuration since it can be moved in parallel and reciprocated endlessly and optimal combing can be performed. It also has a special comb shape and structure that is not found in conventional combs. As a result, regardless of the surface roughness and material of the comb, it is possible to impart luster and stiffness to the hair, correct curly hair, and make the hair smooth and voluminous.

The reason why the operability of the comb has such an effect on the hair and scalp is that the operating speed of the comb is improved, and the contact, friction, and number of peeling between the comb and the hair and scalp are dramatically increased. This is thought to be due to an increase in the amount of static electricity accumulated on the scalp. Therefore, the influence of the comb on the hair and scalp can be further enhanced by forming the surface roughness of each part of the various combs as described below, which is superior in operability.

First, the surface texture of at least the upper and lower surfaces of the barrel and the plurality of teeth located in the vertical direction of the barrel and the plurality of teeth, and the side surface of the barrel located in the opposite direction to the tips of the plurality of teeth is 0.100 μm. It is preferable that Sa is the following, and more preferably that Sa is 0.070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

Next, in addition to the upper and lower surfaces of the barrel and the plurality of teeth located in the vertical direction of the barrel and the plurality of teeth, and the side surface of the barrel located in the opposite direction to the tips of the plurality of teeth, the vertical direction of the shoulder and the tip of the comb It is preferable that the surface texture of the upper and lower surfaces located in the comb, the side surfaces of the shoulders located in the opposite direction from the tips of the teeth, and the side surfaces located in the direction of the tips of the comb tips is Sa of 0.100 μm or less. , 0.070 μm or less of Sa is more preferable. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

and the body, the plurality of teeth, the shoulder, the upper and lower surfaces of the body and the plurality of teeth located in the vertical direction of the comb tip, and the side surfaces of the body and the shoulder located in the opposite direction from the tips of the plurality of teeth, In addition to the side surface located in the direction of the tip of the comb tip, the surface texture of the upper surface and lower surface located in the vertical direction of the comb body, and the side surface of the comb body is preferably 0.100 μm or less Sa. More preferably, the Sa is .070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

Further, although not necessarily required, the surface texture of the side surface facing the plurality of teeth is preferably Sa of 0.100 μm or less, more preferably Sa of 0.070 μm or less. Alternatively, the surface texture thereof is preferably Sz of 1.60 μm or less, more preferably Sz of 1.40 μm or less. Further, it is even more preferable that the surface texture polished to Sa or Sz also has a Sku of 12,000 or less. In addition, the surface roughness must be reduced until Sa is 0.100 μm or less and Sz is 1.00 μm or less, or Sa is 0.100 μm or less and Sku is 7 By reducing the surface sharpness to 0.000 or less, the combing effect is dramatically enhanced.

On the other hand, since the handle of the comb body and the comb operation auxiliary body do not come into contact with hair, it is not necessarily necessary to mirror the surface of the handle itself. However, since it has a stain-preventing effect and can impart a luxurious appearance to the entire comb, it is desirable that Sa is at least 0.100 μm or less, and more preferably 0.070 μm or less.

The material of the comb with a form and structure with excellent operability and/or an optimized surface shape is not particularly limited, but may be made of resin, glass fiber-reinforced resin, carbon fiber-reinforced resin, ceramics, metal, alloy, It is preferable to use at least one selected from iron-based alloys, from the viewpoint of the strength, lifespan, corrosion resistance, molding process, etc. of the comb.

For example, resin materials include general thermoplastic or thermosetting general-purpose plastics, polyamide (PA), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), polyimide (Polyimide), e, PI), Polyoxymethylene (POM), Polytetrafluoroethylene (PTFE), Phenolic resin, Polyolefin, Ultra-high molecular weight polyethylene resin (Ultra Hi) gh Molecular Weight Polyethylene, UHMWPE), Engineering plastics such as acrylonitrile-butadiene-styrene copolymer (ABS) resins, and resins selected from these reinforced with glass fibers or carbon fibers are used as materials for the comb. Further, various ceramics, metals such as iron, alloys such as brass, and iron-based alloys such as stainless steel can be exemplified as materials for the comb. It is preferable to mold using at least one selected from these.

Among these, combs using metals, alloys, and iron-based alloys as materials are preferable, iron-based alloys are more preferable, and carbon steel, special steel, and stainless steel are even more preferable. . Considering that electrolytic polishing and chemical polishing are applied in addition to mechanical polishing, stainless steel is most preferable.

When using metals and alloys as materials for the comb, those with magnetism are preferable, and iron-based alloys with magnetism are particularly preferable. And stainless steel is even more preferred. As already mentioned, the scientific basis for preferring magnetic metals and alloys is unknown, but experimental results suggest that the earth's magnetic field is involved in combs made of magnetic materials, and the effects of these combs on hair and scalp. It is assumed that this will become noticeable. Similarly, it is thought that as the operating speed of the comb increases, the influence of the magnetic comb on the hair and scalp increases.

In order to maintain the surface shape of the comb, metals and alloys are preferable, and in particular, those having a Brinell hardness (HB) after tempering of 150 or more, or having a Brinell hardness (HB) after tempering of 55 or more. Metals and alloys having a Rockwell hardness (HRC) of .

Furthermore, when the material of the comb is an iron-based alloy, considering the above magnetism and hardness, C content: 0.80% or more and 1.35% or less, Si content: 0.25% or less, Mn content: It has a chemical composition of 0.35% or less, P content: 0.03% or less, S content: 0.006% or less, Ni content: 1.30% or less, Cr content: 0.50% or less. Carbon steel, C content: 1.00% or more and 1.50% or less, Si content: 0.30% or less, Mn content: 0.30% or less, P content: 0.025% or less, S content Special steel having a chemical composition: amount: 0.02% or less, Cr content: 0.15% or more and 0.50% or less, V content: 0.50% or less, W content: 2.50% or less, C content: 3.00% or less, Si content: 1.00% or less, Mn content: 1.00% or less, P content: 0.04% or less, S content: 0.03% or less, Ni content: 0.49% or less, Cr content: 4.50% or more and 20.0% or less, Mo content: 5.00% or less, V content: 3.00% or less, W content: 6 It is preferable to use stainless steel with a chemical composition of .00% or less and a Co content of 8.00% or less. Considering that electrolytic polishing and chemical polishing are applied in addition to mechanical polishing, the C content : 3.00% or less, Si content: 1.00% or less, Mn content: 1.00% or less, P content: 0.04% or less, S content: 0.03% or less, Ni content : 0.49% or less, Cr content: 4.50% or more and 20.0% or less, Mo content: 5.00% or less, V content: 3.00% or less, W content: 6.00% Hereinafter, stainless steel having a chemical composition with a Co content of 8.00% or less is more preferable.

Combs made from iron-based alloys not only add luster and body to the hair, correct curly hair, and make hair smooth and voluminous, but also remove various substances that adhere to the pores and hair. It is extremely effective in removing waste products and oil-based hair styling products. Therefore, although the scientific basis is unclear, it is thought that iron-based alloys with such chemical compositions have a strong interaction with various waste products attached to pores and hair, as well as oil-based hair products. .

As mentioned above, in order to maximize the effects of the material, the comb of the present invention must have higher magnetism and have a Brinell hardness (HB) of 150 or more after tempering, or a Rockwell hardness after tempering. (HRC) of 55 or more, carbon steel, special steel, and stainless steel; molded from a single iron-based alloy of any of the above-mentioned carbon steel, special steel, and stainless steel, which has an even more preferable chemical composition. However, depending on the layer configuration, a wide range of materials such as metals, alloys, and ceramics can be used as the base material. Further, although there are various configurations for the cladding material, it is preferable to use a configuration in which the contact area between the base material and the hair is large. Specifically, single lay (2 layers on the entire surface), center lay (2 layers with inner layer), side lay (2 layers with lining), double side lay (2 layers with parallel lining), UD side lay (3 layers with lining on both sides) , reverse lay (3 layers with uneven surfaces on both sides), all inlay (3 layers on the entire surface), center inlay (3 layers with inserts), side inlay (3 layers with flattening), double side inlay (3 layers with parallel flattening), single edge Cladding materials in configurations such as lays (with side panels), double edge lays, and multiple laminations can be used.

As mentioned above, it has the effect of removing excess sebum adhering to the hair and scalp, preventing hair loss and promoting hair growth, as well as adding luster and body to the hair, correcting curly hair, and adding volume to the hair. We have explained in detail that a hair finishing comb that has the effect of making hair smooth and suitable for hairdressing has an optimal surface shape, material, form, and configuration. However, the shape of each part of the comb, such as the body, teeth, shoulders, comb tip, comb body, and handle, as well as their mutual positional relationships, are also important factors in making the above effects more noticeable. I found out.

First, regarding the shape of the teeth, it is preferable that the teeth are vertically asymmetrical, and the upper surfaces of the teeth are linear inclined surfaces or arcuate inclined surfaces. , the lower surfaces of the plurality of teeth are approximately horizontal, and the inclination angle formed by the linear inclined surface and the lower surface or the inclination angle formed by the tangent of the arc-shaped inclined surface and the lower surface is 5° or more and 15° or less. The angle is preferably 3° or more and 12° or less. It is preferable that the tip surface of the tooth tip formed with such an inclined surface is cut at an inclination angle of 39° or more and less than 90° with the lower surface, and preferably 50° or more and less than 80°. More preferred. When operating the comb, it has been experimentally confirmed that the shape of the comb is suitable for adding luster and body to the hair, correcting curly hair, and making the hair smooth and voluminous. . Although the cause is not certain, it is thought to be related to the angle at which the teeth and hair come into contact, and it is assumed that an appropriate inclination of the tip surfaces of the teeth and tooth tips is required.

The tips of the teeth that hang down from the body should be more slanted to add luster and body to the hair, correct curly hair, and make hair smooth and voluminous. more preferred. Specifically, the angle of inclination formed by the linear inclined surface and the lower surface of the tip of the tooth that is vertically installed on the body, or the arc-shaped tip of the tooth that is vertically installed on the body. The tip converging surface is formed such that the angle of inclination formed by the tangent of the inclined surface and the lower surface is 6° or more and 26° or less, and the height of the tooth tip from the lower surface is 0.7 mm or more and 1.1 mm or less. The tip end surface of the tooth tip is cut at an inclination angle of 39° or more and less than 90°, preferably 50° or more and 80° or less with respect to the lower surface.

Regardless of the presence or absence of the converging surface of the tooth tip, the width of the tooth tip tip surface is 0.15 mm or more and 0.45 mm or less, and the length of the tooth tip tip surface is 0.15 mm. The tip end surface of the tooth is cut from the root side at an inclination angle of 36° or more and less than 90°, more preferably 50° or more and 80° or less, so as to form a protrusion of 0.45 mm or more. It is preferable to provide a single-planar tooth tip inclined surface, which is formed as a single plane.However, this new tooth tip inclined surface is provided with a tooth tip right inclined surface and a tooth tip center inclined surface, and the tooth tip is formed from the tooth tip right inclined surface. It is preferable that the central inclined surface is concave. Furthermore, the inclination angle formed by the extension line of the bottom of the tooth tip inclined surface or the tangent to the bottom of the tooth tip central inclined surface with the orthogonal line of the plurality of teeth is 0° or more and 45° or less, and the tooth tip inclined surface, in particular, convergent. It is even more preferable that a groove with a width and depth of 0.05 mm or more and 0.45 mm or less, more preferably 0.05 mm or more and 0.24 mm or less, is provided near the intersection with the surface.

In the shape of the tooth tip above, the inclination angle between the tooth, the tip converging surface, the tip end surface, and the tip inclined surface and the back surface of the tooth is the inclination angle of the tooth, the inclination angle of the tip converging surface, and the tip inclination. It is preferable that the angle of inclination of the surface and the angle of inclination of the tip end surface become larger in this order.

This complex shape of the tips of teeth is closely related to the fact that the average diameter of a single hair is 0.05 mm for Westerners and 0.08 mm for Japanese people. The projections and grooves at the tip of the tip are shaped to loosen entangled hair and allow combing of individual hairs. This shape not only gives shine and body to the hair, corrects curly hair, and makes the hair smooth and voluminous, but also removes various waste products and oil-based hair styling products that adhere to the epidermis of the hair. Can be removed.

In addition to the fine shape of the tips of the comb teeth, the following points should be considered regarding the shape of each part of the comb, such as the body, teeth, shoulders, comb tip, comb body, handle, etc., and their mutual positional relationship. We found that there are important factors such as:

In particular, the thickness of the comb tip is 2.3 mm or more and 2.4 mm or less, the width of the comb tip is 1.5 mm or more and 2.5 mm or less, and the length of the comb tip is 5.5 mm or more and 6.5 mm or less. preferable.

Fourth, the back formed by the shoulder, body, and comb body is a straight line or an arcuate curve, and the inclination angle of the handle with respect to the straight back or the tangent of the back of the arcuate curve is The inclination angle is 26° or more and 46° or less, the tooth length is 4mm or more and 11mm or less, the body width is 0.5mm or more and 4.5mm or less, the tooth width is 0.7mm or more and 1.1mm or less, and the tooth spacing is It is preferable that it is 0.8 mm or more and 1.4 mm or less. In particular, it is more preferable that the tooth width is 0.9 mm or more and 1.0 mm or less, and the tooth interval is 1.0 mm or more and 1.2 mm or less.

Fifth, the thickness of the comb body is 2.5 mm or more and 3.5 mm or less, the width of the comb body is 7 mm or more and 17 mm or less, the length of the comb body is 23 mm or more and 33 mm or less, and the thickness of the handle is 3.5 mm or more4. It is preferable that the length of the handle is 21 mm or more and 31 mm or less, and the total length of the teeth hanging from the body from the tip of the comb tip to the comb body is 50 mm or more and 70 mm or less.

Sixth, in a comb in which the comb main body and the comb operation auxiliary body are pivotally connected, the total length is 160 mm or more and 170 mm or less, the length from the pivot to the tip of the comb tip is 67 mm or more and 77 mm or less, and the length from the pivot to the rear end of the handle. The length from the pivot to the center of the thumb hole is 48 mm to 58 mm, the length from the pivot to the rear end of the moving handle is 90 mm to 100 mm, and the length from the pivot to the center of the thumb hole is 90 mm to 100 mm.

The features of these six shapes are that they untangle tangled hair, make it possible to comb each hair individually, add luster and body to the hair, straighten curly hair, and create smooth, voluminous hair. In addition to this, it can also remove various waste products and oil-based hair styling products that adhere to the epidermis of the hair. Moreover, when combing using the comb of the present invention, the shape is easy to operate without damaging the hair or scalp.

As described above, the optimal surface shape, material, form and configuration for the comb of the present invention, as well as the shape of each part such as the comb body, teeth, shoulders, comb tip, comb body, and handle, and their Although we have explained the mutual positional relationship, etc., as already mentioned in the operating speed of the comb, the combing method using the comb of the present invention can also add luster and body to the hair, correct curly hair, and add volume to the hair. Not only does it make your hair silky smooth, but it also has different effects in removing various waste products and oil-based hair styling products that have adhered to your pores and hair. That is, in the combing method using the comb of the present invention, the upper surface of the comb is directed upward, and the linear or arcuate back formed by the shoulder, body, and comb body of the comb is brought into contact with the scalp. This is a method in which the hair is moved in parallel and reciprocated in all directions along the scalp without touching the scalp. By this combing method, the hair conditioning effect and the removal effect of waste products and oily components adhering to the hair, pores, and scalp can be maximized without damaging the hair and scalp.

According to the comb and combing method of the present invention, without using water, hair wash, permanent chemicals, heat, etc., without damaging the hair or scalp, it can add luster and body to the hair, straighten curly hair, and add volume. Not only can it make your hair silky smooth, but it can also remove sebum, dandruff, and other waste products that adhere to your hair and scalp, keep your hair clean, and prevent hair loss. . The back of the comb of the present invention comes into contact with the scalp and moves back and forth in parallel, providing a scalp massage effect, which improves blood circulation to the scalp and increases the supply of nutrients to the hair, promoting hair growth. You can also expect various effects such as improving curly hair and thinning hair.

The surface shape, material, form, and structure of the comb of the present invention have a large influence on the combing effect, and in particular, if only the surface shape and material of the comb of the present invention are applied to a conventional general comb, the effect can be improved. is expressed. However, the shape and structure of the comb, the shape of each part such as the comb body, teeth, shoulders, comb tip, comb body, and handle, as well as their mutual positional relationship, synergistically produce the combing effect. , is maximized by the combing method of the present invention.

The present invention will be described in more detail below using an embodiment shown in the drawings, but the present invention is not limited thereto, and can be implemented with various modifications within the scope of the gist of the present invention. It is possible to do so, and is limited only by the technical idea described in the claims.

The following three types of materials were used in the embodiment of the comb of the present invention. That is, C content: 0.80% or more and 1.35% or less, Si content: 0.25% or less, Mn content: 0.35% or less, P content: 0.03% or less, S content Carbon steel with a chemical composition of: 0.006% or less, Ni content: 1.30% or less, Cr content: 0.50% or less, has magnetism, and has an HRC of 60 or more after tempering. , C content: 1.00% or more and 1.50% or less, Si content: 0.30% or less, Mn content: 0.30% or less, P content: 0.025% or less, S content: 0.02% or less, Cr content: 0.15% or more and 0.50% or less, V content: 0.50% or less, W content: 2.50% or less, has magnetism, and is hard to heat.

In this example, the comb was made using V Gold 10 (manufactured by Takefu Special Steel Co., Ltd.) as the stainless steel.

However, the present invention is not limited to these as long as the surface shape of the comb is optimized. The optimized surface shape will be explained using the comb in FIG. 1 as an example. In this embodiment, the upper surface of the body 1, the plurality of teeth 4, the shoulder 3, the comb tip 6, and the comb body 7 located in the vertical direction of the body 1, the plurality of teeth 4, the shoulder 3, the comb tip 6, and the comb body 7 is shown. and the lower surface, the body 1, the shoulder 3, and the side surfaces 2, 3-1 of the comb body 7 located in the opposite direction to the tooth tips 4-2-1 of the plurality of teeth 4, and the tip direction of the comb tip 6 Polishing was performed so that the arithmetic mean roughness in the line roughness curve of the surface of each portion of the side surface 6-1 located at was less than 0.050 μm. In this case, resin, glass fiber reinforced resin, carbon fiber reinforced resin, ceramics, metal, alloy, iron-based alloy, etc. can be used.

In the polishing of this embodiment, a polishing method in which buffing, which is mechanical polishing, is used as final polishing was adopted. Specifically, after the comb body shown in FIG. 1 has been cut, each part of the comb is sanded with #400 to #1000 for the three types of iron-based alloys mentioned above, in which the portions of the teeth 4 are further cut with a grindstone. After polishing using paper, buffing was performed as a final finish. Then, buffing is performed using a chromium oxide blue rod and a blue rose buff made of cotton cloth for a mirror finish, and as an intermediate finish, buffing is performed using a chromium oxide blue stick and a blue rose buff made of cotton cloth. Then, as a final finish, two methods were used: buffing using a chromium oxide blue rod and Calico's white rose buff to give a super mirror finish.

The surface roughness of each of the polished parts was measured using a scanning white interferometer (model number New view 600s) manufactured by Zygo in a measurement area of 0.701 mm x 0.526 mm, as shown in Figure 22. Arithmetic mean roughness Sa, maximum height Sz, and kurtosis Sku were calculated based on the formula shown in . Note that no filter was applied, and 4th Order Remove was applied, in which the slightly convexly curved surface of the comb was stretched horizontally.

FIG. 23 shows the results of measuring the surface roughness of the upper surface of the mirror-finished comb body 1 according to an embodiment of the present invention. As is clear from the figure, Sa=0.045 μm, Sz=1.38 μm, and Sku=9.222. (Note that at the time this white interferometer was released, standards for Sa, Sz, and Sku had not been determined, so there was no such notation, and they were displayed as Ra, Rz, and Rku. )

FIG. 24 shows the results of measuring the surface roughness of the upper surface of the comb barrel 1 that has been given a super mirror finish according to an embodiment of the present invention. Sa=0.051 μm, Sz=0.52 μm, and Sku=3.888.

Next, the optimum form and structure of the comb of the present invention will be explained. FIG. 1 shows a schematic diagram from above of a first comb according to an embodiment of the present invention. The body 1 supports a plurality of teeth 4, and the body 1 is provided with eyes 5 having predetermined intervals, and the plurality of teeth 4 are vertically arranged in a row. At the tip of the body 1, comb tips 6 are formed at predetermined intervals between the teeth at the tip of a plurality of teeth 4 via a shoulder 3 extending on the body 1, and on the opposite side, comb tips 6 are formed at predetermined intervals on the teeth at the tip of the plurality of teeth 4. The comb body 7 is extended so that the body 1 extends and expands from the root 4-1-1. A handle 8 extends from the comb body 7 with an inclination in the same direction as the tips 4-2-1 of the teeth 4, and a thumb hole 9 is formed at the rear end of the handle 8.

The conventional structure called a comb, which has a body, a back, teeth, a tooth base, an eye, and a shoulder, has a body 1, a back 2, a tooth 4, a tooth base 4-1, and an eye 5, as shown in Fig. 1. , and the shoulder 3, the comb of the present invention has a comb body 7 formed by extending and expanding the body 1, and from the comb body 7, the tips 4-2-1 of the teeth 4. It is characterized by comprising a handle 8 extending obliquely in the direction and a thumb hole 9 formed in the handle 8. However, when using the above materials and surface shapes, excellent combing effects can be achieved even with conventional comb configurations and configurations. The comb shown in Fig. 1 is an object of the present invention, which uses a comb to add luster and body to hair, correct curly hair, and make hair smooth and voluminous. Combing is a method of removing waste products such as sebum and dandruff, as well as oil-based hair styling products, from the hair to keep it clean. In this case, even if the material and surface shape are not the above, the comb operation speed is fast and an excellent combing effect is achieved.

In order to make the structure of the first comb shown in FIG. 1 easier to understand, FIGS. 2 and 3 show a schematic side view as seen from the tooth 4 side and a schematic side view as seen from the back 2 side, respectively. .

FIG. 4 shows a schematic diagram from above of a second comb according to an embodiment of the present invention. The comb main body 12 has substantially the same structure as the first comb described in FIG. 1, except for the main part 17, so a description thereof will be omitted. The feature of the second comb is that the comb operation auxiliary body 16, which is integrally equipped with a movable handle 13, a ring finger hole and a little finger rest formed at one end of the movable handle 13, is located approximately at the center of the comb body 7 of the comb body 12. The comb body is characterized in that it is pivotally connected to the comb main body by a pivot 17 extending over a shaft so as to be rotatable through a predetermined rotation angle. Since the movable handle 13 is rotated and used due to the pivotal connection between the comb body 12 and the comb operation auxiliary body 16, the outer edge of the comb body 12 has a ring finger hole 14 formed therein and a thumb hole 9 formed therein. A buffer point 10 is provided at a portion that contacts the provided outer edge, and a contact point 11 having the same structure as a pair of scissors is provided to make it easier for the movable handle 13 to rotate.

Regarding the second comb, in order to make its structure easier to understand, FIGS. 5, 6, and 7 include a schematic diagram as seen from the back side, a side schematic diagram as seen from the tooth 4 side, and , a side schematic view seen from the dorsal 2 side.
