Description

  The present invention relates to a heat generating plate for permanents used when applying a permanent wave to hair.

2. Description of the Related Art Conventionally, permanent wave treatment (hereinafter referred to as permanent treatment) has been performed on hair for the purpose of beauty, correction of curly hair, or facilitation of hair care. The permanent treatment is for forming a wave on the hair by heat or a chemical reaction and holding the formed wave for a certain period of time. For example, the permanent treatment is performed as follows.
(1) First, wrap the hair around a perm rod.
(2) Then, apply the first permanent agent to the hair and leave it for about 5 to 40 minutes. Thus, the first agent is allowed to penetrate into the hair. In addition, the 1st agent for permanents contains reducing agents, such as thioglycolic acid, thioglycolate, cysteine, cysteine hydrochloride, cysteamine, a sulfurous acid, for example. In addition, since the wave is easily formed when the first agent penetrates sufficiently, it is preferable to apply heat to the hair so that the first agent penetrates into the hair.
(3) Next, the excess first agent is washed away.
(4) Subsequently, a second agent for permanent is applied to the hair. The second agent contains an oxidizing agent such as bromate and hydrogen peroxide.
(5) Then, remove the permanent rod and wash away the excess second agent.
(6) Finally, the hair is dried with a dryer or the like to finish.

  The perm treatment as described above will be briefly described. In (2), the reducing agent permeates into the hair, thereby decomposing the hair protein bond (so-called cystine bond). Then, with the hair wound around the perm rod, an oxidizing agent is allowed to act on the hair in (4) above. Then, cystine bonds are formed again in the hair. As a result, the hair is given a shape in which the hair is wound around the permanent rod, that is, a wave shape.

  On the other hand, in such a perm treatment, there is a case where the wave does not easily stick to the hair, or the attached wave may not be held for a long time. This can be attributed to, for example, the hair quality (thickness, hardness, etc.) of the patient and the state of the hair (pain condition, etc.). More specifically, it is conceivable that the first agent does not penetrate uniformly and sufficiently depending on the hair quality and the state of the hair.

As a countermeasure in this case, it is conceivable to effectively apply heat to the wound hair, and as a means for realizing this, a permanent rod provided with a heater inside the main body is considered (for example, patent document). 1).
2005-137441

  By the way, according to the perm rod as described in Patent Document 1, since the perm rod itself generates heat, heat is applied only to the hair part wound around the perm rod, in other words, the part where the wave is to be formed. Can be. For this reason, it is thought that a 1st agent can fully osmose | permeate into the part which wants to form the wave.

  However, when a heater is incorporated in the permanent rod, the weight of the permanent rod increases, so that when a large number of permanent rods are used, the burden on the patient increases. Moreover, the following problems can be considered.

  When winding hair around a permanent rod, first, the tip of the hair is wound around the permanent rod, and finally, the root portion of the hair is wound. Then, the tip of the hair directly touches the perm rod and heat is easily applied, and conversely, the base portion of the hair becomes difficult to apply heat.

  That is, among the hair wound around the perm rod, the tip of the hair (the inner part of the outer periphery of the perm rod) becomes hot, and the basic part of the hair (the outer part of the outer perm of the perm rod) The temperature becomes low, and there is a possibility that the temperature may be uneven and the formation of the wave may be uneven.

  Furthermore, since the tip part of hair is generally easily painful, it is not preferable to apply extra heat. On the contrary, since the root portion of the hair is generally difficult to be waved, it is desired that heat is more easily applied than the tip portion of the hair.

  The present invention has been made in view of these points, and an object of the present invention is to enable heat to be effectively applied to the root portion of the hair in the permanent treatment.

The present invention made to achieve the above object is a permanent heating plate for gripping a wound hair and attaching the wound hair to the wound hair.
First, the permanent heating plate has a heating element that generates heat when energized, and the heating element is held by the plate body of the permanent heating plate. Further, the plate body is configured to have flexibility while holding the heating element. Further, the permanent heating plate is provided with form holding means for holding the form of the plate main body in the form of gripping hair.

In addition, the permanent heating plate is provided with a current supply means for supplying a current from an external power source to the heating element.
Such a permanent heat generating plate can be used in the following manner in a permanent treatment for attaching a wrinkle in a state where the hair is wound around the hair (hereinafter also referred to as a wave shape). .

  First, the hair is wound around the permanent rod, and the hair is held together with the permanent rod by the permanent heating plate. In this case, since the plate main body has flexibility, the form of the plate main body can be transformed into a form in which the plate main body is surely in contact with the hair wound around the perm rod. The form of the plate body is held in the deformed form by the holding means.

  Then, the heating element is energized through the current supply means to generate heat. This causes heat to be applied to the hair. In other words, heat is applied to the hair to give it a wave shape.

  By the way, when the hair is wound around the perm rod and heat is applied to the hair to form a wave shape, more heat is applied to the outer part of the outer periphery of the perm rod. It is preferable to be added. This is because the root portion of the hair, which is difficult to form the wave shape, is wound around the outer portion of the permanent rod.

  That is, when the hair is wound around the permanent rod, first, the tip portion of the hair is wound, and the root portion of the hair is wound last. For this reason, when the wave shape is effectively applied, it is necessary to sufficiently apply heat to the root portion of the hair, that is, the outer portion of the permanent rod around which the root portion is wound.

  In this regard, if this heat generating plate for permanents is used, it is possible to grip the permanent rod from the outside with the plate body and apply heat to the hair wound around the permanent rod. Heat can be effectively applied to the part. In addition, since the plate main body and the hair can be surely contacted, the effect is remarkable.

  On the other hand, since heat is applied from the outer part of the permanent rod, it is possible to prevent heat from being applied to the inner part of the permanent rod more than necessary, and it is wound around the inner part of the permanent rod. It can prevent that the front-end | tip part of hair hurts.

Moreover, in this heat generating sheet for permanents, since it is not necessary to incorporate a heater or the like that generates heat, the weight can be reduced, and the burden on the patient is not increased.
Furthermore, since the plate body has flexibility as described above, it is possible to easily attach or remove the permanent heating plate to or from the hair. That is, the user (beautician) can easily perform the permanent process.

  Here, the heat generating plate for the permanent can be configured as in claim 2. In other words, in the heat generating plate for permanent use according to claim 2, the plate body is composed of the first plate and the second plate which are welded to each other, and the heat generating body is held between the first plate and the second plate. It has come to be. Specifically, it is conceivable that a heating element is sandwiched between the first plate and the second plate, and the first plate and the second plate are vapor-deposited with each other.

  According to such a configuration, since the heating element is not exposed and the heating element does not directly contact the hair, the heating element generates heat more than necessary and damages the hair. Can be prevented.

  And as a 1st plate and a 2nd plate, it is preferable to use a polyimide resin as described in Claim 3. A polyimide resin is suitable because it is excellent in heat resistance and chemical resistance. Further, a polyetherimide resin may be used. This polyetherimide resin is more excellent in heat resistance than the polyimide resin. Further, polycarbonate (PC), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), or the like may be used.

  Next, the heating element may be provided as in claim 4. That is, in the heat generating plate for a permanent magnet according to claim 4, the heating element is composed of a linear conductor, and the linear conductor is reciprocated several times in a fixed direction so as to form a striped pattern. It is.

  In such a heat generating plate for permanents according to claim 4, in particular, if the conductor is arranged so that the stripe pattern is uniform, that is, the stripe has a certain width, heat is uniformly generated from the plate body. Therefore, it is possible to prevent unevenness in heat generation, and consequently unevenness of the wave shape. Further, the heating temperature can be adjusted by adjusting the width of the stripes. That is, if the width between the conductors is increased, the heat generation temperature can be suppressed, and if the width between the conductors is reduced, the heat generation temperature can be increased. .

  Moreover, as a heat generating body, it is good to use the metal which plastically deforms as described in Claim 5. According to this, the form at the time of deform | transforming a plate main body can be hold | maintained also by the plastic force which the metal as a heat generating body has.

  A permanent heating plate according to claim 6 is the permanent heating plate according to any one of claims 1 to 5, wherein the shape holding means is a clip member. 7. The clip member according to claim 6, wherein the clip member is provided so as to cover all or a part of the plate body on the surface of the plate body opposite to the side that holds the hair, and the plate body is closed. Is held in the form of holding the hair.

  Here, more specifically, the clip member has an action point, a fulcrum point, and a force point, and by applying a constant force to the force point, a constant force acts on the action point and the action point moves. It is comprised as follows. In particular, the clip member also has a configuration that generates an elastic force, and in order to move the action point, it is necessary to apply a force repelling the elastic force to the force point.

  In the permanent heating plate according to claim 6, in a state where no force is applied to the force point of the clip member, the clip member is in a closed form, that is, a form capable of gripping hair. In a state where a force is applied to the force point of the clip member (for example, a state in which the clip member is “pinch”), the clip member is opened.

According to the configuration of claim 6 using such a clip member, it is easier to attach and remove the permanent heating plate.
A permanent heating plate according to a seventh aspect is the permanent heating plate according to the first to fifth aspects, wherein the shape holding means is a wire member that can be plastically deformed. The wire member is linearly provided on the surface of the plate body opposite to the side that holds the hair.

  In such a heat generating plate for permanents according to claim 7, when the plate body is deformed, the wire member is plastically deformed, and the form of the plate body is maintained in the form after the plastic deformation of the wire member. And according to such a structure, the form of a plate main body can be changed easily. For this reason, it becomes possible to easily hold the hair with the heat generating plate for permanent or to remove the heat generating plate for permanent from the hair. Only one wire member or a plurality of wire members may be provided.

By the way, a battery is considered as an external power source for supplying a current to the heating element. And when using a battery, what is necessary is just to comprise like Claim 8.
In other words, in the permanent heat generating plate according to the eighth aspect, the current supply means includes a battery accommodating portion for accommodating the battery, and is configured to supply a current from the battery to the heating element.

This eliminates the need for an energizing cord for connecting the heat generating plate for the permanent and the external power source, and makes it easy for the user (hairdresser) to handle.
Here, in order to prevent the heat generation temperature of the heating element from rising more than necessary and damaging the hair, it is preferable to configure as in claims 9 and 10.

  First, the permanent heating plate according to claim 9 is the permanent heating plate according to claims 1 to 8, wherein the temperature detection means for detecting the heating temperature of the heating element, and the heating temperature of the heating element detected by the temperature detection means. Temperature notification means for notifying the surroundings.

  Specifically, it is conceivable to provide a temperature sensor and a display unit that displays the temperature detected by the temperature sensor. Moreover, you may make it provide a thermometer and a thermograph sheet | seat (what a display color changes with temperature).

According to this, since the user (beautician) can easily know the heat generation temperature, it is possible to prevent the heat generation temperature from rising more than necessary.
Moreover, if it comprises like Claim 10, it will be more reliable.

  That is, the permanent heating plate according to claim 10 is the permanent heating plate according to claim 9, further comprising temperature determination means for determining whether or not the heating temperature of the heating element detected by the temperature detection means is equal to or higher than a predetermined value. I have. When the temperature determination means determines that the heat generation temperature of the heating element is equal to or higher than a predetermined value, the current supply stopping means stops the supply of current from the current supply means to the heating element.

  According to this, even if the user (beautician) does not pay particular attention to the heat generation temperature, if the heat generation temperature exceeds a predetermined value, the supply of current to the heat generation body is stopped and the heat generation body does not generate heat. . For this reason, it can prevent more reliably that exothermic temperature raises required and damages hair.

Embodiments of the present invention will be described below with reference to the drawings.
[Embodiment 1]
FIG. 1 is a view showing a heat generating plate for permanents (hereinafter simply referred to as a heat generating plate) 1 of the present embodiment. 1A, 1B, and 1C are a plan view, a side view, and a back view of the heat generating plate 1, respectively.

  The exothermic plate 1 in FIG. 1 is used when a permanent wave treatment (hereinafter referred to as a permanent treatment) is applied to the hair. Specifically, the shape of the hair wound around the hair ( Hereinafter, it is referred to as a wave shape). The contents of the perm processing are as described in [Background Art]. Moreover, the case where the heat generating plate 1 of the present embodiment is used will be described later.

  As shown in FIG. 1A, the heat generating plate 1 according to the present embodiment includes a holding plate 10, a heat generating wire 20, a wire member 30, and an energizing cord 40. Hereinafter, each component will be described.

  First, as shown in FIGS. 1B and 1C, the holding plate 10 includes a first plate 11 and a second plate 12 and has a substantially square shape. The first plate 11 and the second plate 12 are made of polyimide resin. Polyimide is a polymer having a thermally and chemically stable molecular structure, and is excellent in terms of heat resistance, mechanical strength, electrical insulation, chemical resistance, and the like. The holding plate 10 is configured to be flexible, in other words, bendable.

  The holding plate 10 is not limited to a square shape, and may have any shape, for example, a triangular shape, a rectangular shape, a rhombus shape, or any other polygonal shape, An elliptical shape or the like may be used, and various shapes can be formed according to the assumed use situation. For example, depending on the length of the hair to be permed, the part of the hair head (top or collar), the part of the hair itself (whether the tip or root), or the shape of the wave to be formed It can be considered that the shape of the plate 10 is configured to be easy to use.

  Next, the heating wire 20 is made of stainless steel and has a thickness of several micrometers to several tens of micrometers. The heat generating wiring 20 is provided between the first plate 11 and the second plate 12 of the holding plate 10. Specifically, the heating wire 20 is vapor-deposited on the first plate 11 and the second plate 12 while being sandwiched between the first plate 11 and the second plate 12.

  Further, as shown in FIG. 1A, the heating wiring 20 includes a specific side (hereinafter referred to as side s) of the holding plate 10 and a side opposite to the side s (hereinafter referred to as side u). To be reciprocated a plurality of times. Hereinafter, the other two sides of the side s and the side u are referred to as sides t and v, respectively.

  First, the heating wire 20 is configured such that the portion disposed closest to the side t is undulated along the side t. Further, the portion disposed closest to the side v is configured to wave along the side v. In other parts, the line is arranged linearly between the side s and the side u, and in the vicinity of the side s and the side u, the path of the heat generating wiring 20 is folded 180 degrees and arranged. Thereby, it is comprised so that a striped pattern may be formed.

  The width of the striped pattern, that is, the width of the heating wire 20 and the width of the portion where the heating wire 20 is not provided can be arbitrarily determined. For example, if the total length of the heat generation wiring 20 is reduced to increase the width of the portion where the heat generation wiring 20 is not disposed, the heat generation temperature can be suppressed, and the total length of the heat generation wiring 20 is increased. If the width of the portion where the heating wiring 20 is not disposed is reduced, the heating temperature can be raised. Of course, the heating wiring 20 may be arranged in any way. For example, you may arrange | position so that a grid-like pattern may be formed. Moreover, you may comprise in the shape of one plate.

  Further, the heat generating wiring 20 is provided with terminals 21 and 22 for connection with the energization cord 40. Each of the terminals 21 and 22 is connected to the high potential side (plus side) of the external power supply via the energization cord 40 and the other is connected to the low potential side (minus side) of the external power supply. In the present embodiment, the heating wire 20 and the energization cord 40 are welded together by the terminals 21 and 22.

  Next, the wire member 30 is an iron wire, and is bonded to the holding plate 10 with an adhesive tape. When the holding plate 10 is bent, the holding plate 10 is held in its bent form. The wire member 30 may be bonded with an adhesive or the like, or may be welded. The wire member 30 can be made of any plastically deformable material such as a copper wire or a brass wire.

  Here, FIG. 2 is a perspective view of the heat generating plate 1. First, FIG. 2A shows a state in which the holding plate 10 is bent in such a manner that one end of the holding plate 10 where the energization cord 40 is provided and the other end facing the one end are not in contact with each other. In this case, the shape of the holding plate 10 is held by the plastic force of the wire member 30 in the state of FIG. Further, as shown in FIG. 2B, if the holding plate 10 is bent so that one end and the other end are in contact with each other, the holding plate 10 in the state shown in FIG. Ten forms are retained. In this way, the shape of the holding plate 10 is held in any way within a range where the wire member 30 is not damaged by the plastic force of the wire member 30.

  Next, the energization cord 40 is used to supply current from the external power source to the heat generating wiring 20. Here, as an external power source, for example, a converter that converts alternating current into direct current can be considered.

  And the electricity supply cord 40 is provided with the terminal 41 connected to power supply devices, such as a converter, for example. In addition, the other end of the energization cord 40 with respect to one end where the terminal 41 is provided is connected to the terminal 21 of the heating wire 20. With such a configuration, a voltage output from the power supply device is applied to the heat generation wiring 20, and a current flows through the heat generation wiring 20, so that the heat generation wiring 20 generates heat. In addition, the other end of the energizing cord 40 opposite to the terminal 41 is provided with a clip that is made of a conductor and can be opened and closed, and the energizing cord 40 is attached to or detached from the terminal 21 by opening and closing the clip. You may be able to do that.

According to such a heat generating plate 1, as described below, the wave shape can be effectively applied to the hair.
First, in the perm treatment, when the hair is wound around the perm rod and the wound shape is applied to the hair, the heating plate 1 holds the hair together with the perm rod. In this case, since the holding plate 10 has flexibility, the form of the holding plate 10 can be transformed into a form in which the holding plate 10 is surely in contact with the hair wound around the perm rod, In addition, the form of the holding plate 10 is held in the deformed form by the wire member 30. And if the electricity supply cord 40 is connected to a power supply device and the heat generating plate 1 generates heat, heat can be effectively applied to the hair.

  Specifically, according to the heat generating plate 1, heat can be effectively applied to the root portion of the hair. The reason for this will be described. When the hair is wound around the permanent rod, first, the tip portion of the hair is wound, and the root portion of the hair is wound last. In other words, the root portion of the hair is wound around the outer portion of the hair rod in the permanent rod. And according to this heat_generation | fever plate 1, hair can be hold | gripped with the perm | rod for rod from the outer side of the perm | rod for rods, For this reason, heat can be added by the root part of hair.

  Therefore, according to the heat generating plate 1, a wave shape can be reliably attached to the root portion of the hair. In addition, since heat is applied from the outer part of the permanent rod, it is possible to prevent excessive heat from being applied to the inner part of the permanent rod, and the tip of the hair that is wound around the inner part of the permanent rod. It can prevent that part hurts.

Next, how the heat generating plate 1 of the present embodiment as described above is used in the permanent processing will be described more specifically.

Specifically, the voltage applied to the heat generating plate 1 is adjusted by operating the power supply device. In addition, the voltage is adjusted between 5-30V. In this step, the hair is heated for about 5 to 40 minutes.
(1-5) Then, exothermic plate 1 and perm rod 100 are removed from the hair, and then a second agent for perm is applied to the hair. Then, leave it for about 1 to 15 minutes. The second agent contains an oxidizing agent such as bromate and hydrogen peroxide.
(1-6) Then, the excess second agent is washed away.
(1-7) Finally, the hair is dried with a dryer or the like to finish.
<Method 2>
Next, the second method will be described. The second method is the same as the first method in that the heat generating plate 1 is used, but the use timing is different.

(2-3) Then, using the heating plate 1, the hair is grasped together with the permanent rod 100.
(2-4) Next, the energization cord 40 connected to the heat generating plate 1 is connected to the power supply device, and the heat generating wiring 20 of the heat generating plate 1 is energized. The detailed contents are as described in (1-4) of Method 1.
(2-5) Then, exothermic plate 1 and perm rod 100 are removed from the hair, and then a second agent for perm is applied to the hair. Then, leave it for about 1 to 15 minutes. The second agent is as described above.

<< Comparison Experiment 2 >>
In Comparative Experiment 2, an experiment was conducted on a method of heating hair using a preheated preheated clip.

  Although not shown, the preheating clip is configured so that the hair can be sandwiched, and the material thereof is Zylon (registered trademark). Note that Zylon (registered trademark) is a resin excellent in heat resistance and the like.

  Further, the procedure of the permanent process in the comparative experiment 2 is the same as the procedure of the permanent process in the experiment 1. On the other hand, in the comparative experiment 2, the preheating clip is used instead of the experimental heating plate of experiment 1.

In Comparative Experiment 2, a stainless steel rod having a diameter of 20 mm heated to 130 degrees was sandwiched between preheating clips, and the preheating clips were heated for 15 minutes. And (D) of Experiment 1
In the process corresponding to the above, the hair was sandwiched with a heated preheating clip, and the hair was heated.

In this comparative experiment 2, the preheating clip was about 130 degrees immediately after heating, but its temperature dropped to about 40 degrees two minutes after the hair was sandwiched.
Next, each experimental result will be described with comparison. FIG. 4 is a diagram showing hair having a wave shape formed by perm treatment in Experiments 1 and 2 and Comparative Experiments 1 and 2.

  As shown in FIG. 4, each of the hairs subjected to the perm treatment of Experiments 1 and 2 has a firm wave shape at the root of the hair. On the other hand, the hair subjected to the perm treatment in Comparative Experiment 1 has a wave shape at the hair tip but does not have a sufficient wave shape at the root. Even when compared with Experiments 1 and 2, the wave shape is clearly weak. Further, the hair subjected to the permanent treatment of Comparative Experiment 2 has almost no wave shape.

  Here, in order to compare the difference between the permanent treatment of Experiment 1 and the permanent treatment of Comparative Experiment 1, a model wig with human hair implanted was used, and the permanent hair of Experiment 1 was applied to the hair of the model wig. The treatment and the permanent treatment of Comparative Experiment 1 were performed. Specifically, the hair implanted in the model wig was divided into two, one was subjected to the perm treatment of Experiment 1 and the other was subjected to the perm treatment of Comparative Experiment 1. The model wig is not particularly shown.

  And the hair of Experiment 1 in FIG. 4, the hair of Comparative Experiment 1, and the model wig were evaluated by five hairdressers (hairdressers A to E). Evaluation is based on whether the hair in Experiment 1 in FIG. 4 and the hair in Comparative Experiment 1 have a strong wave shape at the base of the hair, and whether the wave shape is uniform throughout. It was performed from the viewpoint of whether the model wig is preferable (for example, whether the appearance is preferable).

  First, regarding the degree of strength (strength) of the wave shape, all of hairdressers A to E evaluated that the strength of the wave shape of the root part of the hair of Experiment 1 (see FIG. 4, the same applies hereinafter) is strong and sufficient, It was evaluated that the strength of the wave shape of the root portion of the hair of Comparative Experiment 1 (see FIG. 4, the same applies hereinafter) was weak.

  Regarding the uniformity, all the hairdressers A to E evaluated that the hair of Experiment 1 had a sufficient wave shape at the tip part and was uniform as a whole, and the hair of Comparative Experiment 1 had a wave at the tip part. The shape was weaker than the root part and was evaluated as non-uniform as a whole.

  In addition, for the model wigs, all the hairdressers A to E evaluated that the side subjected to the perm treatment in Experiment 1 had a uniform and uniform wave shape from the root to the tip of the hair, and the appearance was also favorable. The side subjected to the perm treatment in Experiment 1 was evaluated as undesirable because the wave shape of the root portion was weak and the wave shape of the tip was further weak, which was uneven overall.

  As described above, when the permanent treatment is performed using the heat generating plate 1 of the present embodiment, a firm wave shape can be formed on the root portion of the hair, and the hair from the root to the tip can be uniformly distributed as a whole. It is possible to finish so as to be able to perform a permanent treatment that is highly appreciated by hairdressers.
