Description

The present invention relates to a hair comb that is used when a hair dye, a hair dye, or a hair straightener is applied to the hair for hair dyeing or hair straightening.

Conventionally, what is generally used as a method of dyeing hair is a two-component oxidative hair dye and an acid hair dye using an acid dye. And in the case of hair dye, in order to avoid skin irritation caused by hydrogen peroxide or alkali, in order to avoid skin irritation, leave the hair a little away from the base and use a brush or hair dyeing comb on the hair. It is common to apply. However, it is very difficult to apply to the hair at the root portion near the scalp, the vellus hair and the hairline of the scalp, and a high level of technology has always been required.
In the case of acidic hair dyes, there is a big problem that when the drug is attached to the scalp, it is easy to dye the scalp and cannot be easily removed. -It is common to apply about 1 cm away from the ground to avoid damage to the hair roots or scalp with a reducing agent or alkaline agent contained in the first agent in the form of gel or gel.

Furthermore, the hair has a life of 3 to 6 years, and the hair cycle is repeated in the order of developmental period, growth period, regression period, and resting period, and the growth rate extends by about 1 cm per month. For this reason, hair that has been dyed and straightened must be dyed or straightened once every 1 to 2 months. Therefore, treating the root of hair is extremely important for hairdressing and beauty, and advanced techniques are required. For hairdressing and beauty technicians, in order to apply hair dyes, hair dyes and hair straighteners so that they do not adhere to the background, it is particularly delicate to treat the hair roots, hair production and hairline. In short, advanced technology is required.

By the way, when applying a hair dye or a hair straightener to hair and dyeing it, generally a hair coating is used.
Are in use. As such a hair comb, for example, a comb tooth portion is formed by arranging a required number of comb teeth side by side on an elongated base, and a tapered gripping portion is formed at one end of the base. An integrally formed one is known (for example, see Patent Document 1).
When applying hair dyes or hair straighteners to the hair using the above-mentioned hair comb,
Slice the hair to about 1 cm width using the tapered gripping part of the comb, attach a hair dye or hair straightener to the comb, remove excess chemicals, and then remove the hair from the root of the sliced hair The operation of applying with a comb is repeated, and all the heads are dyed.

JP-A-9-308520 (5th page, FIG. 5)

By the way, in the conventional hair comb, the base and each comb tooth base are formed thick in order to give the strength of the comb, and the thickness of the base is usually 3.0 mm to 4.4. 5 mm, the thickness of the root portion of the comb teeth is 3.0 mm to 4.0 mm, and the thickness of the tip portion of the comb teeth is 0.6 mm to 1.0 mm. As described above, the conventional hair combs are not only difficult to see the scalp and the tip of the comb teeth due to the thick base and comb roots, but also the hair and hair of the roots and hairs near the scalp. When processing, there is a problem that it is difficult to check with the naked eye and it is very difficult to perform detailed work. In addition, the thickness of the comb teeth, the width of the comb teeth, and the width between the comb teeth are not formed in consideration of the amount of hair coloring or hair straightening agent attached and the amount of combing the hair with a comb. When treating the hair at the base near the scalp and the hair growth or hairline of the head hair, a large amount of drug adheres to one part of the base, and the scalp is dyed, and the hair dyeing and curly hair straightening effect becomes uneven. There was a problem that it was easy.

As a result of intensive studies in view of the above points, the present invention solves the problems of the conventional examples, and the hair dye / hair dye or hair straightener does not adhere to the scalp, and it is applied to the scalp without limit. An object of the present invention is to propose a comb for hair that has an effect that can be applied to the hair at the root of near hair, the head hair, and the hairline, and is capable of neatly extending the hair dyed or curly hair.

In order to achieve the above object, the invention described in claim 1 of the present application is configured such that a comb tooth portion is formed by arranging a necessary number of substantially tapered comb teeth side by side on an elongated base. A hair comb in which a tapered gripping part is integrally formed at one end, and the thickness of the base part and the base part of each comb tooth is 0.8 m.
m to 2.0 mm, the tip portion thickness of each comb tooth is 0.3 mm to 0.8 mm, and the grip portion thickness is 2.0.
The gist of the present invention is a hair comb characterized by being set in a thin shape of mm to 3.5 mm.

The invention according to claim 2 is characterized in that the width of each comb tooth is 0.3 mm to 0.7 mm, and the width between adjacent comb teeth is 0.7 mm to 1.2 mm. The gist of the hair is described.

As described above, the invention according to claim 1 of the present invention is formed such that the base, the root portion of each comb tooth, the tip portion of each comb tooth, and the gripping portion are thinner than the conventional example. Therefore, when used, the scalp and root can be easily confirmed with the naked eye.
Or, the hair straightener can be applied evenly to the hair of the root and the hair and hairline near the scalp without sticking to the scalp, and the hair of the root can be dyed as close to the scalp as possible. It can correct hair and curly hair.

As described above, since the width of each comb tooth and the width between adjacent comb teeth are set appropriately as described above, the invention according to claim 2 of the present application appropriately sets the amount applied to the hair and the amount of hair combing. It can be adjusted, and as a result, can be uniformly applied to the hair surface at the root.

It is a side view which shows one Example of this invention. It is a top view which shows one Example of this invention. It is an expanded sectional view which follows the II line | wire of FIG. It is an expanded sectional view which follows the II-II line of FIG. It is the A section enlarged side view of FIG.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on one Example shown on drawing.
1 to 5 show an embodiment of the present invention, in which 1 is a hair comb, 2 is an elongated base constituting the comb 1, and 3 is the base 2 A comb-teeth portion 5 is formed by arranging a required number of substantially taper-like comb teeth 4 in parallel along the longitudinal direction, and is a tapered gripping portion integrally formed at one end of the base 2. is there.

Then, the base 2 is a thickness D ₁ is 0.8Mm～2.0Mm, particularly preferably 1.2Mm～1.5Mm. When the thickness D _{1 of the} base 2 is less than 0.8 mm, the elasticity of the comb 1 is lost to the elasticity of the hair when a hair dye / hair dye or a hair straightener is applied to the hair. Not only is it difficult to apply, but the operability is poor and detailed work is not possible. 2.0
If it exceeds mm, the range of the blind spot is widened, and since the background and the tips of the comb teeth 4 of the comb 1 cannot be confirmed with the naked eye, fine work is impossible.

The base portion thickness D ₂ of each comb tooth 4 is 0.8 mm to 2.0 mm, and particularly preferably 1.
2 mm to 1.5 mm. If it is less than the thickness D ₂ of the root portion of the comb teeth 4 is 0.8 mm, not only easy to comb teeth 4 are broken, the hair dye between comb teeth 4, hair dye or the amount of medicament straightening agent, less The hair dyeing and curly hair straightening effects are weakened. On the other hand, if it exceeds 2.0 mm, the amount of the hair dye / hair dye between the comb teeth 4 or the chemical agent of the hair straightener will increase, so that the amount of application will increase and adhere to the scalp or irritate.

The thickness D ₃ of the tip end portion of the comb teeth 4 is 0.3 mm to 0.8 mm, particularly preferably 0.4.
mm to 0.6 mm. When the thickness D ₃ of the tip portion of the comb teeth 4 is less than 0.3 mm, not only the comb teeth 4 are easily broken, but also the amount of the hair dye, hair dye, or hair straightener between the comb teeth 4 is small. Become
Hair dyeing and curly hair straightening effects are weakened. In addition, if it exceeds 0.8 mm, the amount of the hair dye / dyeing agent between the comb teeth 4 or the hair straightener will increase too much, so the amount of hair applied at the base of the hair will increase, and the scalp will be stained. It will be stimulating.

The thickness D ₄ of the grip portion 5 is 2.0Mm～3.5Mm, particularly preferably, 2.5 m
m to 3.0 mm. When the thickness D ₄ of the grip portion 5 is less than 2.0 mm, when applying a hair dye / hair dye or a hair straightener to the hair, it is difficult to operate because of its elasticity, and the fit of the hand is poor. On the other hand, if it exceeds 3.5 mm, it is not flexible and is too hard, so the operability is poor. Moreover, since the shape of the holding part 5 is slightly rounded, the comb easily slides down from the hand. Therefore, the grip portion 5 is formed into a flat shape, so that the fit is good and the comb is not easily slipped off from the hand.

Furthermore, the width W _{1 of the} comb teeth 4 is 0.3 mm to 0.7 mm, and particularly preferably 0.4 mm.
mm to 0.5 mm. If the width W _{1 of the} comb teeth 4 is less than 0.3 mm, the teeth are weak and difficult to form. On the other hand, if the thickness exceeds 0.7 mm, the amount of combing hair increases, and the hair dye or hair straightener does not adhere uniformly to the hair surface, resulting in uneven dyeing.

The width W ₂ between the comb teeth 4 is 0.7 mm to 1.2 mm, particularly preferably 0.8 mm to
1.0 mm. When the width W ₂ between the comb teeth 4 is less than 0.7 mm, the amount of the hair dye / hair dye or the hair straightener attached to the hair decreases, and the hair dyeing or hair straightening effect is weakened. Also,
If the thickness exceeds 1.2 mm, the amount attached to the root part near the scalp and the hair on the hair and hairline increases, which is not preferable because it tends to adhere to the scalp.

In addition, examples of the material of the hair comb 1 of the present invention include polypropylene, polyethylene, ABS resin, AS resin, polyamide, polyacetal, phenol resin, polyvinyl acetate resin, fluororesin, natural rubber, and butyl rubber. And silicone resins, acrylic resins, epoxy resins, vinyl chloride resins, bamboo, and metals.

Next, the hair combs of Examples 1 to 3 formed to the dimensions shown in Table 1, and Comparative Examples 1 and 2
Hair hair, hair coloring and hair straighteners are applied to the hair with a hair comb to make the scalp easy to see, easy to apply at the root, easy to apply on the hair and hairline, An evaluation test was conducted on adhesion, ease of holding the grip portion 5, uniformity during application, hair dyeing and curly hair straightening effects, and the results are shown in Table 2.

As is apparent from the evaluation results in Table 2 above, the hair combs 1 of Examples 1 to 3 are the base 2,
By reducing the thicknesses D ₁ , D ₂ , and D ₃ of the roots of the comb teeth 4 and the tips of the comb teeth 4, when the scalp is confirmed with the naked eye, the range of blind spots becomes narrower, so It can be seen that the tips of the comb teeth 4 can be easily seen, the agent is easily applied to the base of the hair, the vellus hair and the hairline, and there is little adhesion to the scalp. In addition, since the thickness D ₄ of the grip portion 5 is set to be thinner than that of the comparative example, it is very easy to grip when applying to the root portion of the hair, the vellus hair or the hairline, and the workability is improved. You can see that
On the other hand, as is apparent from the evaluation results of Comparative Examples 1 and 2 in Table 2 above, according to Comparative Examples 1 and 2, since the thickness of the base of the comb and the root of the comb tooth is thick, the blind spot becomes wide. It can be seen that not only it is difficult to check the scalp with the naked eye, but also it is difficult to apply to the root part, hair production and hairline, and the hair dye tends to adhere to the scalp.

In addition, as is apparent from the evaluation results in Table 2, by properly adjusting the width W _{1 of} the comb teeth 4 and the width W ₂ between the comb teeth 4, the amount of hair combing and the amount of drug to be applied are properly controlled. It can be adjusted and when hair is dyed at the root of the hair, on the hair or at the hairline, it can prevent the hair dye from adhering to the scalp, and the hair dye or hair straightener is applied to the hair root. In this case, it can be seen that the drug can be uniformly applied to the hair surface, and there is a sufficient hair dyeing effect and curly hair straightening effect.
On the other hand, as is clear from the evaluation results of Comparative Examples 1 and 2 in Table 2 above, according to Comparative Examples 1 and 2, the width of the comb teeth and the width between the comb teeth is poor, and the Comparative Example In No. 1, the amount of hair combing is small, and the amount of drug adhering to the hair surface near the scalp is small, so the adhesion to the scalp is reduced.
However, the hair dyeing effect and the hair straightening effect are getting worse. Further, in Comparative Example 2, the amount of the adhering drug is large, and the amount of hair combing is too large, so that the amount attached to one part of the hair surface is increased, the adhesion to the scalp is seen, and it is applied in a non-uniform state. It can be seen that the hair dyeing effect and the curly hair straightening effect are poor.
