  In the hair removal tool as described above, if the abrasive particles having a large polishing power are used, body hair can be removed easily and reliably, but on the other hand, the skin irritation is too strong and the skin is easily damaged. There is. On the other hand, if abrasive particles with low polishing power are used to moderate skin irritation, waste hair cannot be removed cleanly even if it is rubbed or rubbed. There is a problem that can be lost. That is, in general, if importance is attached to the ease and certainty of hair removal, the risk of damaging the skin will be great, and conversely, if priority is given to the gentleness to the skin, the hair removal effect will inevitably decrease. become. It is difficult to find a practical hair removal tool that satisfies these two conflicting requirements at the same time.

  The present invention has been made in view of the above-described circumstances, and is intended to provide a hair removal tool that is excellent in ease and certainty of hair removal and that does not cause excessive irritation to the skin. .

  In order to solve the above-described problems, a hair removal tool according to the present invention is a hair removal tool in which a flexible polishing sheet for hair removal is fixed on the surface of a base, and the base is JIS K6400-2. It is formed of a soft foam material having a hardness of 200 to 350 N according to D method, and the polishing sheet for hair removal is obtained by attaching an abrasive to the surface of a substrate with a synthetic resin binder. The mixing ratio of the abrasive is 1: 1.5 to 2.2 (parts by weight) (claim 1).

  In using the hair removal tool, the user holds the base by hand and rubs the hair removal polishing sheet against the skin to be subjected to unwanted hair removal. There is no limitation on how to rub, but for example, it is preferable to rub so as to draw a small circle. In addition, it is preferable to repeat clockwise rubbing and counterclockwise rubbing alternately several times without releasing the hair removal tool from the skin.

  When the skin is rubbed with the hair removal tool, the binder of the hair removal polishing sheet acts so as to capture and pull the body hair by the frictional resistance of the surface. And the hair is cut from the root by the abrasive particles hitting the pulled hair. In particular, a portion effective for cutting hair is a peripheral edge portion of the polishing sheet for hair removal.

  In general, when shaving the body hair with a razor, the razor blade itself cuts the hair while pulling the hair, so that the shape of the cut portion is usually sharp, and the shaving mark is usually tinged. On the other hand, according to the hair removal tool of the present invention, the hair in a state of being sufficiently pulled by the resin surface of the binder is cut with an abrasive, so that the hair end of the cut portion is rounded. Therefore, there is no tingling after hair removal as in the case of shaving with a razor.

  In the present invention, as a first structural feature, the hardness of the base formed of a soft foam material is 200 to 350 N (JIS K6400-2 D method). This hardness value is characterized in that it is larger than the hardness value of a soft foamed material that has been generally used as a base for a hair removal tool in the past (thus, the base is harder than the conventional one). Moreover, in this invention, the mixing ratio of the said binder and the said abrasive | polishing material shall be 1: 1.5-2.2 (weight part) in the said abrasive sheet for hair removal as the 2nd characteristic on a structure. That is, the present invention is characterized in that the blending ratio of the binder is larger than the conventional one, and the blending ratio of the abrasive is smaller than the conventional one.

  In the present invention, due to the first feature, the support strength of the hair removal polishing sheet by the base is high. For this reason, when the said hair removal tool is applied to skin, the surface of the said binder will be strongly pressed against hair, and a bigger frictional resistance will arise with respect to hair. Thereby, hair will be hold | maintained more strongly and will be pulled and this will contribute to the improvement of a hair removal effect.

  Moreover, in this invention, since the mixture ratio of the said binder is larger than the said conventional thing by the said 2nd characteristic, the said binder catches hair in a more extensive resin surface. Therefore, it contributes to the improvement of hair removal efficiency. In addition, since the blending ratio of the abrasive is smaller than the conventional one, the contact with the skin becomes soft.

  According to the present invention, since both the first feature and the second feature are provided, it is possible to satisfy the conflicting demands of ensuring gentleness to the skin and realizing a good hair removal effect at the same time.

  As one preferred embodiment, in the polishing sheet for hair removal, an embodiment in which the individual particles of the abrasive are distributed in the binder so as to be horizontally long on the surface of the substrate (invoice) Item 2).

  The particles of the abrasive are usually not in a regular shape such as a spherical shape, but in a shape having irregular irregularities on the surface and having a length or a long axis as a whole. In the conventional abrasive sheet, the abrasive particles are distributed in the binder so as to be vertically long on the surface of the substrate. On the other hand, in one embodiment of the present invention, the individual particles of the abrasive are distributed in the binder so as to be horizontally long on the surface of the substrate. Thereby, the protrusion amount of the abrasive particles from the surface of the binder becomes small, and the angle of the protruding end of the abrasive particles becomes an obtuse angle or close thereto. Therefore, the irritation to the skin is softened and there is no need to worry about damaging the skin.

  As a preferred embodiment, the abrasive has a particle size of No. 400 to 1000, and the individual particles are distributed in the binder so as to be horizontally long on the surface of the substrate. An embodiment in which the actual polishing power when rubbing corresponds to the polishing power of an abrasive having a particle size of 800-1500 is exemplified.

  Further, as another preferred embodiment, in the hair removal polishing sheet, a cushion material layer is provided between the base material and the binder layer to enhance followability to skin irregularities. The aspect which is done is illustrated (Claim 4). In this way, the presence of the cushion material layer improves the followability of the polished surface to the skin, so that the surface of the binder and the particles of the abrasive material reliably hit the hair even in uneven skin. . Therefore, the hair removal effect is further improved.

  As a preferred embodiment, an embodiment in which the peripheral shape of the hair removal polishing sheet is wave-shaped is exemplified (Claim 5).

  The polishing sheet for hair removal effectively cuts hair particularly at the peripheral edge portion. If the peripheral shape of the hair removal polishing sheet is a wave shape, the peripheral length of the hair removal polishing sheet is longer than when the peripheral shape of the hair removal polishing sheet is linear. Become. Therefore, since the effect | action which cuts hair increases, the hair removal effect improves further.

  Moreover, when the shape of the periphery of the polishing sheet for hair removal is linear, when the skin is rubbed in the direction of the straight line, linear streak marks are formed on the skin by the linear edge. However, if the peripheral shape of the hair removal polishing sheet is a wave shape, even if the hair removal polishing sheet is applied to the skin and moved in any direction, streak marks are left on the skin. There is no such thing.

  Furthermore, if the peripheral shape of the hair removal polishing sheet is a wave shape, the peripheral edge of the hair removal polishing sheet easily adapts to the unevenness of the skin, so that hair is hardly left behind and the hair removal effect is further improved. There is also an advantage to improve.

  As a preferred embodiment, a mode is illustrated in which a recess is formed on at least a part of the periphery of the base for holding fingers when the hand is rubbed against the skin. 6). If it does in this way, since the said base is easy to hold | maintain with fingers, hair removal work is easy.

  As another preferred embodiment, the polishing sheet for hair removal is fixed to the surface of the base, and a flexible polishing sheet for polishing is fixed to the back surface of the base. The polishing sheet for polishing is An abrasive having particles smaller than that of the abrasive of the hair removal abrasive sheet is attached to the surface of the base material with a synthetic resin binder, and the binder and the abrasive in the polishing abrasive sheet An embodiment in which the blending ratio is 1: 1.5 to 2.8 (parts by weight) is exemplified (claim 7).

  In addition, as a preferred embodiment, in the polishing sheet for polishing, an example in which the individual particles of the abrasive are distributed in the binder so as to be horizontally long on the surface of the base material is illustrated. (Claim 8).

  Furthermore, in the polishing sheet for glossing, the abrasive has a particle size of 2000 to 6000, and the individual particles are distributed in the binder so as to be horizontally long on the surface of the substrate. An example in which the actual polishing power when rubbing the skin corresponds to the polishing power of an abrasive having a particle size of 4000 to 12000 is exemplified.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  Drawing 1 is a figure showing the whole hair removal tool composition concerning one embodiment of the present invention, (a) is a front view of a hair removal tool, (b) is a side view, (c) is a rear view. is there. 2 is a partially enlarged sectional view of a polishing sheet constituting the hair removal tool of FIG. 1, FIG. 3 is a sectional view of a polishing sheet as a comparative example of FIG. 2, and FIG. 4 is a drawing of the hair removal tool of FIG. It is a perspective view which shows the usage method.

  First, the schematic structure of the hair removal tool of FIG. 1 and its usage will be described.

  As shown in FIG. 1, a hair removal tool 1 according to an embodiment of the present invention includes a base 2 made of a soft foam material, and a flexible hair removal polishing sheet 3 fixed to the surface of the base 2. And a flexible glossy polishing sheet 4 fixed to the back surface of the base 2.

  The base 2 acts as a support for supporting both the hair removal polishing sheet 3 and the glossing polishing sheet 4, and serves as a gripping portion by the user during hair removal work. Accordingly, the size of the base 2 is set such that a person can hold the periphery with fingers.

  The hair removal polishing sheet 3 and the glossing polishing sheet 4 are fixed to the base 2 with their respective abrasive surfaces facing outward. As a fixing method, adhesion by an adhesive is common. The two polishing sheets 3 and 4 have different polishing forces. That is, the hair removal polishing sheet 3 has a relatively large polishing force so that the main hair removal action can be achieved, and the gloss removal polishing sheet 4 is removed by the hair removal polishing sheet 3. It has a relatively small polishing power so that the skin that has been bristled can be finished glossy.

  The hair removal tool 1 of FIG. 1 can be used as shown in FIG. The user holds the base 2 by hand and rubs the hair removal polishing sheet 3 against the skin to be subjected to unwanted hair removal. As a rubbing method, it is preferable to rub so as to draw a small circle. Moreover, it is preferable to repeat the clockwise rubbing and the counterclockwise rubbing alternately several times without releasing the hair removal tool 1 from the skin. After the hair removal, the base 2 can be turned upside down and changed, and the skin can be rubbed with the gloss polishing sheet 4 to finish it glossy. In addition, the user of the dry skin with few water | moisture contents or oil in skin can acquire a favorable hair removal effect by applying water or cream to skin beforehand. According to the said hair removal tool 1, hair removal can be performed efficiently only by rubbing skin. In addition, there is an effect that blood circulation is promoted by rubbing the skin, and old cells of the skin are scraped off to promote metabolism.

  Next, the configuration of the hair removal tool 1 will be described in detail.

  As shown in FIG. 1, the said base 2 has the surface 5 and the back surface 6 which are mutually parallel, and is equipped with the area and thickness suitable for the hair removal work by hand. The shape of the base 2 is not limited. However, in the illustrated example, the shape of the surface 5 and the back surface 6 in which eggs are projected on a plane is adopted in consideration of ease of holding and visual softness. ing.

  It is preferable that a recess 7 is formed on at least a part of the periphery of the base 2 so that a user can put his / her finger on the skin when holding the base 2 with his / her hand. This is because it becomes easy to hold the base 2 with fingers. In the illustrated example, a recess 7 having a uniform cross-sectional shape is formed along the peripheral surface of the base 2. In this way, the manufacturing of the base 2 is facilitated, and even if the position of the peripheral surface is held, the feeling when it is held by hand is uniform, which is preferable. As described below, since the base 2 has an appropriate hardness, there is no inconvenience that the shape of the base 2 is greatly deformed even if the user puts his / her finger on the recess 7 and holds it.

  The base 2 is made of a soft foamed resin or a soft porous body. Specific examples of the material include soft urethane, foamed polyethylene, and foamed ethylene vinyl acetate copolymer. In this embodiment, soft urethane foam (soft urethane sponge) is used.

  The soft foamed resin used as the base 2 is preferably 200 to 350 N in hardness according to JIS K6400-2 D method. Particularly preferred hardness is 250 to 310N. These numerical values indicate that the base 2 of the present embodiment is harder than that conventionally used as the base of the hair removal tool.

  Since the base 2 is a support for the two polishing sheets 3 and 4, the harder one has higher support strength of the polishing sheet. However, if it is too hard, it will not be able to follow curved surfaces such as arms and legs, and will also cause skin damage. As a result of earnest test research, the inventors specified the numerical range as hardness that facilitates hair removal work, is preferable in terms of the support strength of the polishing sheet, and also ensures followability to a curved surface. . In addition, the specific value to be used in the numerical range is determined by considering the blending ratio of the binder and the abrasive in each of the polishing sheets 3 and 4, and the hair removal effect is maximized, and Select an appropriate value that minimizes the degree of skin damage.

  In addition, the hardness test of the JIS K6400-2 D method is as follows. A test piece of 380 mm × 380 mm × 50 mm is laid flat on a table of a testing machine and compressed with a circular pressure plate having a diameter of 200 mm, and the thickness of the test piece when a force of 5 N is applied is set to the initial thickness. Next, after pressing the pressure plate at a speed of 100 mm / min for a distance of 75% of the original thickness, the pressure plate was immediately returned, and the pressure plate was immediately immediately returned at a speed of 100 mm / min to 25% of the original thickness. Measure the force when 20 seconds have passed since it stopped. The measured value (N) of this force is taken as the hardness of the test piece.

  Next, as shown in FIG. 2, the hair removal polishing sheet 3 is obtained by attaching an abrasive 8 to the surface of a substrate 10 with a synthetic resin binder 9. When the abrasive surface of the hair removal abrasive sheet 3 is viewed microscopically, some of the particles of the abrasive 8 are exposed and distributed on the surface of the binder 9. The resin surface 9a of the binder 9 has an action of hooking (or adsorbing) the hair with its frictional resistance when performing the hair removal work, and pulling the hair. On the other hand, the abrasive 8 has an effect of cutting the hair pulled by the resin surface 9 a of the binder 9. Particularly, a portion effective for cutting hair is abrasive particles in the peripheral edge portion 11 (see FIG. 1) of the hair removal polishing sheet 3.

  As the kind of the abrasive 8, a material that has been conventionally used as abrasive particles, such as aluminum oxide, silicon carbide, silicon oxide, diamond, and the like, can be appropriately used. Here, alumina powder is exemplified as an example from the viewpoint of availability and economy. The particle size of the abrasive 8 is preferably 400 to 1000, and 600 (# 600) is exemplified as an example.

  As the kind of the binder 9, a synthetic resin type conventionally used as a binder for an abrasive sheet, such as a phenol resin, an epoxy resin, polyurethane, or polyester, can be appropriately used. Whichever resin is used, it is preferable to mix a synthetic rubber resin with it and use it as a composite adhesive because the frictional resistance against the hair becomes larger and the hair can be reliably captured.

  The base material 10 can be appropriately selected from conventionally known materials as the base material of the abrasive sheet, but in view of gentleness to the skin and water resistance, for example, a plastic sheet or a cloth material is used. It is common.

  In the hair removal polishing sheet 3, the blending ratio of the binder 9 and the abrasive 8 (hereinafter referred to as “resin / abrasive blending ratio”) is binder: abrasive = 1: 1.5-2. 2 (parts by weight) is preferred. In particular, when the soft foamed resin has a hardness of 250 to 310 N, the resin / abrasive blending ratio is preferably 1: 1.85 (parts by weight).

  As already described, the binder 9 has an effect of catching and pulling the hair by frictional resistance when the surface 9a comes into contact with the hair. On the other hand, the abrasive 8 has an effect of cutting the hair pulled by the resin surface 9 a of the binder 9. Therefore, the larger the blending ratio of the binder 9, the greater the hair capturing action. However, in that case, since the blending ratio of the abrasive 8 is small, the hair cutting action is small. If the blending ratio of the abrasive 8 is increased, the hair cutting action increases, but in that case, the action of capturing the hair by the binder 9 is reduced, and the skin may be damaged by the abrasive 8. Is big. As a result of earnest test research from such a viewpoint, the inventors specified the numerical range as a resin / abrasive grain ratio that has a high hair removal effect and is also gentle to the skin.

The inventors actually performed a hair removal test on six types of abrasive sheets for hair removal with different resin / abrasive grain blending ratios. There are 5 subjects. Each subject had their hair removed with 6 types of hair removal tools in which each hair removal polishing sheet was bonded to a base having a common hardness (made of foamed urethane foam having a hardness of 280 N). The results were evaluated numerically with a maximum of 10 points, and comments were also asked for the feeling of use. The results of the hair removal test are shown in Table 1.

  Also from this table, it can be seen that the vicinity of the abrasive grains 2.2 (parts by weight) relative to the resin 1 is the upper limit value of the abrasive compounding ratio. If the abrasive grain ratio is larger than this (the binder ratio is small), the skin irritation will be too strong. It can also be seen that the area around 1.5 (parts by weight) of the abrasive grains relative to the resin 1 is the lower limit value of the abrasive grain blending ratio. If the abrasive grain ratio is too small (the binder ratio is large), it is difficult to remove hair, and it can be said that the skin is unsuitable due to the frictional resistance of the binder. Among these, a particularly suitable blending ratio can be said to be around 1.55 to 1.85 (parts by weight) with respect to the resin 1.

  It should be noted that the specific ratio used in the numerical range is determined by taking into account the relationship with the hardness of the base 2 (200 to 350 N in terms of hardness according to JIS K6400-2 D method). An appropriate value is selected so that the hair effect is maximized and the degree of skin damage is minimized. By setting the hardness of the base 2 and the resin / abrasive grain ratio within the above numerical range, the conflicting demands of ensuring gentleness to the skin and realizing a good hair removal effect can be satisfied at the same time.

  As shown in FIG. 2, in the hair removal polishing sheet 3, the individual particles of the abrasive 8 are distributed in the binder 9 so as to be horizontally long on the surface of the substrate 10. preferable. The particles of the abrasive are usually not in a regular shape such as a spherical shape, but in a shape having irregular irregularities on the surface and having a length or a long axis as a whole. In the conventional polishing sheet 3 ′, the particles of the abrasive 8 ′ are distributed in the binder 9 ′ so as to be vertically long on the surface of the substrate 10 ′ as shown in FIG. 3. On the other hand, in this embodiment, the individual particles of the abrasive 8 are distributed in the binder 9 so as to be horizontally long on the surface of the substrate 10. Thereby, the protrusion amount of the particles of the abrasive 8 from the surface 9a of the binder 9 becomes small, and the angle of the protrusion end of the abrasive particles becomes an obtuse angle or close to it. Therefore, the irritation to the skin is softened and there is no need to worry about damaging the skin.

  When the abrasive 8 is distributed in the binder 10 in the landscape orientation (laying posture), the polishing power is lower than when the abrasive is distributed in the portrait orientation. The abrasive 8 has a particle size of 400 to 1000, and the individual particles are distributed in the binder 9 so as to be horizontally long on the surface of the base material 10, whereby the actual polishing when the skin is rubbed. A mode in which the force corresponds to the polishing power of an abrasive having a particle size of 800 to 1500 is illustrated as a suitable example.

  In order to distribute the abrasive 8 in a posture in which it is laid down in the binder 9, for example, coating may be performed using a comma coater known as a coating machine. That is, the base material is fed by a roller while supplying a coating material obtained by mixing the abrasive 8 and the binder 10 together with an appropriate solvent to the surface of the base material, and the base material is supplied to the roller. It passes between the coating thickness setting bodies arranged with a gap corresponding to the total value of the thickness of the raw material and the coating thickness. As a result, the coating material is applied to the surface of the base material with a uniform predetermined thickness, and the particles of the abrasive 8 are distributed in the coating material while being laid down.

  As shown in FIG. 2, in the present embodiment, in the hair removal polishing sheet 3, a cushioning material for enhancing the followability to skin irregularities between the base material 10 and the binder 9 layer. Layer 12 is interposed. The presence of the cushioning material layer 12 improves the followability of the polished surface to the skin, so that the resin surface 9a of the binder 9 and the particles of the abrasive 8 will surely hit the hair even with uneven skin. Therefore, the hair removal effect is further improved.

  As a material for the cushion material layer 12, for example, rubber, polyester, polyurethane, or the like can be used.

  Moreover, as shown in FIG. 1, in this Embodiment, the shape of the circumference | surroundings of the said polishing sheet 3 for hair removal is made into wave shape. The hair removal polishing sheet 3 cuts hair effectively, particularly at the peripheral edge portion 11 thereof. And if the shape of the periphery of the said hair removal polishing sheet 3 is made into a wave shape, compared with the case where the shape of the periphery of the said hair removal polishing sheet 3 is a linear shape or a curved shape close thereto, The peripheral length of the polishing sheet 3 becomes longer. Therefore, since the effect | action which cuts hair increases, the hair removal effect improves further.

  Further, if the shape around the hair removal polishing sheet 3 is a straight line or a curved line close thereto, when the skin is rubbed in the direction of the line, a straight streak mark is formed on the skin by the edge of the polishing sheet. End up. However, if the peripheral shape of the hair removal polishing sheet 3 is a wave shape, even if the hair removal polishing sheet 3 is applied to the skin and moved in any direction, streaks are left on the skin. There is no such thing.

  Furthermore, if the peripheral shape of the hair removal polishing sheet 3 is a wave shape, the peripheral edge of the hair removal polishing sheet 3 easily adapts to the unevenness of the skin, so that hair is not easily left behind and the hair removal effect. There is also an advantage of further improving.

  Next, the gloss polishing sheet 4 will be described. Similarly to the hair removal polishing sheet 3, the glossing polishing sheet 4 is obtained by attaching an abrasive to the surface of a base material with a synthetic resin binder. The major difference from the hair removal polishing sheet 3 is the abrasive particle size and the resin / abrasive blending ratio. Matters not particularly specified for the glossing polishing sheet 4 are substantially the same as those for the degreasing polishing sheet 3.

  In the polishing sheet for polishing 4, the grain size of the abrasive is preferably 2000 to 6000, for example, 4000 (# 4000). Since the particle size of the abrasive is much larger than that of the hair removal polishing sheet 3 (the particle size is small), it is preferable to use a plastic sheet having no irregularities on the surface as the substrate.

  In the polishing sheet for glossing 4, the blending ratio (resin / abrasive blending ratio) of the binder and the abrasive is preferably 1: 1.5 to 2.8 (parts by weight). In particular, when the hardness of the base made of the soft foam resin is 250 to 310 N, the resin / abrasive blending ratio is preferably 1: 2.20 (parts by weight).

  In the polishing sheet 4 for glossing, the binder has an effect of giving the skin gloss by rubbing the skin with the resin surface. On the other hand, the abrasive mainly acts to scrape old cells of the skin. Therefore, if the blending ratio of the binder is large, the effect of giving gloss to the skin is increased. However, in that case, since the blending ratio of the abrasive is small, the action of removing old cells is small. Increasing the blending ratio of the abrasive increases the effect of removing old cells, but in that case, it is necessary to take care not to damage the skin. As a result of diligent test research from such a viewpoint, the inventors specified the numerical range as a resin / abrasive grain ratio in which both the glossing action and the old cell removal action are achieved at a high level. is there.

  It should be noted that the specific ratio to be used in the numerical range is an appropriate value that maximizes the gloss effect and minimizes the degree of skin damage in consideration of the relationship with the hardness of the base. Select a number. By setting the hardness of the base and the resin / abrasive grain ratio in the numerical range, it is possible to simultaneously satisfy the conflicting demands of removing old cells and shining the skin without damaging the skin.

Also in the abrasive sheet 4 for the polish, it is preferable that the individual particles of the abrasive material are distributed in said binder so that the horizontally elongated on the surface of the substrate. In this case, the polishing power is lower than when the abrasive is distributed in a vertically long posture. By setting the abrasive particle size to 2000 to 6000 and distributing the individual particles in the binder so as to be horizontally long on the surface of the base material, the actual polishing force when rubbing the skin is the particle size. A mode corresponding to the polishing power of No. 4000-12000 abrasive is illustrated as a suitable example.

Similarly to the hair removal polishing sheet 3, the gloss polishing sheet 4 is provided with a cushioning material layer between the base material and the binder layer to enhance followability to skin irregularities. It is preferable to wear.

  Moreover, as shown in FIG. 1, it is preferable that the peripheral shape of the second polishing sheet is also a wave shape, similar to the hair removal polishing sheet.

  The inventors of the present invention created a hair removal tool having the following configuration as an example of the present invention. The shape is the same as that shown in FIG.

Base: Made of ether-based urethane foam Hardness is 280N (JIS K6400-2 D method)
Polishing sheet for hair removal Base material: Cotton cloth Abrasive material: Alumina powder (particle size # 600)
Binder: Resin adhesive in which synthetic rubber resin is mixed with polyester Resin / abrasive compounding ratio: 1: 1.85 (parts by weight)
Polishing polishing sheet Substrate: Plastic sheet Abrasive: Alumina powder (grain size 4000)
Binder: Polyester adhesive Resin / abrasive compounding ratio: 1: 2.20 (parts by weight)
As a result of actually performing a hair removal test using the hair removal tool, it was possible to quickly remove the hair without noticing the skin, and the feeling of use was also refreshing.
