Description

Technical Field

[0001] The present invention relates to a hair growth method and a jig for assisting hair growth work.

Background Art

[0002] Conventionally, hair materials have been adhered to natural hair for hair growth or makeup. In this adhesion work, it is necessary to manually adhere the hair materials sequentially at positions as close as possible to the roots of a large number of natural hairs. Moreover, since the hair materials to be adhered are very thin, the adhesion work is difficult, and a long time is required for adhering a large number of them. Therefore, a method of tying hair for hair growth to natural hair has been developed (for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the natural hair grows, as a result of the knot moving to the tip side, the knot becomes conspicuous. In order to avoid this, it is necessary to redo the hair growth. As a result, the method of Patent Document 1 is also not an easy method.

[0005] In view of such circumstances, the present invention aims to provide an adhesion method and an adhesive applicator that can more easily adhere natural hair and artificial hair than before.

Means for Solving the Problems

[0006] The present invention relates to an adhesive applicator for adhering artificial hair or human hair to a base hair using a liquid adhesive, comprising a first adhesive holding member, a second adhesive holding member located at a position away from the first adhesive holding member, and a connecting portion connecting the proximal ends of the first adhesive holding member and the second adhesive holding member, wherein the base hair and the artificial hair or the human hair can be inserted into the gap between the first adhesive holding member and the second adhesive holding member.

[0007] The gap between the first adhesive holding member and the second adhesive holding member preferably can hold the adhesive.

[0008] When defining the surface of the first adhesive holding member that holds the adhesive as the first adhesive holding surface and the surface of the second adhesive holding member that holds the adhesive as the second adhesive holding surface, when viewed from the longitudinal direction of the first adhesive holding member or the second adhesive holding member, the distance between the first adhesive holding member and the second adhesive holding member preferably becomes narrower as it goes from the first adhesive holding surface side or the second adhesive holding surface side towards the other. The distance between the first adhesive holding member and the second adhesive holding member preferably becomes narrower as it goes from one side to the other side in the thickness direction.

[0009] The present invention relates to an adhesive method for adhering artificial hair or human hair to a base hair using the above adhesive applicator, comprising an adhesive holding step of holding the liquid adhesive in the gap between the first adhesive holding member and the second adhesive holding member, an insertion step of inserting the base hair and the artificial hair or the human hair between the first adhesive holding member and the second adhesive holding member, and a feeding step of moving the adhesive applicator along one side to the other side of the base hair and the artificial hair or the human hair, wherein the base hair in the insertion step is arranged to be along the artificial hair or the human hair.

[0010] The present invention relates to an adhesion method for adhering artificial hair or human hair to a base hair using a liquid adhesive, comprising an insertion step of inserting the base hair and the artificial hair or the human hair between bifurcated structures holding the adhesive, and a feeding step of moving the adhesive applicator along one side to the other side of the base hair and the artificial hair or the human hair, wherein the base hair in the insertion step is arranged to be along the artificial hair or the human hair.

[0011] In the feeding step, it is preferable that the posture of the bifurcated structure is such that the tip end is on the one side rather than the base end. Further, it is preferable to include a return step of moving the adhesive applicator along the other side to the one side of the base hair and the artificial hair or the human hair.

[0012] In the insertion step, it is preferable that the base hair and the artificial hair or the human hair are temporarily fixed.

Advantages of the Invention

[0013] According to the present invention, it is possible to provide an adhesion method and an adhesive applicator that can more easily adhere base hair and artificial hair than in the prior art.

Embodiments for Carrying Out the Invention

[0015] As shown in FIGS. 1 to 2, the adhesive applicator 2 is for adhering the ground hair GM and the artificial hair EX using a liquid adhesive, and includes a handle 10 and a bifurcated structure 20 attached to the handle 10.

[0016] Hereinafter, for convenience of explanation, an arbitrary direction in the horizontal plane is defined as the X direction, a direction orthogonal to the X direction among arbitrary directions in the horizontal plane is defined as the Y direction, and a direction orthogonal to the horizontal plane is defined as the Z direction.

[0017] The handle 10 extends in the X direction. The bifurcated structure 20 is provided at the X-direction end of the handle 10 and extends in the X direction.

[0018] The bifurcated structure 20 includes a first adhesive holding member 21 for holding the adhesive, a second adhesive holding member 22 for holding the adhesive, and a connecting portion 25 attached to the handle 10.

[0019] The connecting portion 25 connects the proximal ends of the first adhesive holding member 21 and the second adhesive holding member 22, and has a V-shaped cross-sectional shape in the XY plane (FIG. 3). Therefore, a groove 25M is formed in the upper surface 25U of the connecting portion 25. The connecting portion 25 may be formed by bending a plate-like body extending in the X direction along a bending line BL (FIG. 1) extending in the X direction, or may be formed, molded, or cut so as to have a V-shaped cross-sectional shape.

[0020] The first adhesive holding member 21 is formed in a plate shape and is provided so as to protrude from the connecting portion 25 in the X direction. The second adhesive holding member 22 is also formed in a plate shape and is provided so as to protrude from the connecting portion 25 in the X direction. The second adhesive holding member 22 is arranged so as to be spaced apart from the first adhesive holding member 21 in the Y direction. A gap 20X between the first adhesive holding member 21 and the second adhesive holding member 22 allows the ground hair GM and the artificial hair EX to be inserted. Also, a liquid adhesive can be held in the gap 20X between the first adhesive holding member 21 and the second adhesive holding member 22.

[0021] As shown in FIG. 4, it is preferable that the first adhesive holding member 21 becomes higher in the Z direction as it goes from the central portion in the Y direction to the end portion in the Y direction of the adhesive applicator 2. Similarly, it is preferable that the second adhesive holding member 22 becomes higher in the Z direction as it goes from the central portion in the Y direction to the end portion in the Y direction of the adhesive applicator 2. Also, the first adhesive holding member 21 and the second adhesive holding member 22 are preferably arranged so as to have a U-shaped cross-sectional shape in the XY plane. Thereby, the ground hair GM, the artificial hair EX, and the adhesive are easily guided into the gap 20X formed in the central portion in the Y direction of the bifurcated structure 20.

[0022] Note that the surface of the first adhesive holding member 21 on which the adhesive is held (the first adhesive holding surface) and the surface of the second adhesive holding member 22 on which the adhesive is held (the second adhesive holding surface) are preferably smoothly connected to the inclined surface portion of the V-shaped cross section of the connecting portion 25. Also, when viewed from a direction orthogonal to the XY plane, the gap 20X between the first adhesive holding member 21 and the second adhesive holding member 22 preferably coincides with the recessed portion of the V-shaped portion.

[0023] As shown in FIG. 5, the gap 20X between the first adhesive holding member 21 and the second adhesive holding member 22 preferably includes a guiding gap 20X1 and an insertion gap 20X2. The guiding gap 20X1 gradually narrows in width W1 (length in the Y direction) from the tip side toward the base end side. The insertion gap 20X2 has a constant width W2 (length in the Y direction) from the tip side toward the base end side. In the insertion gap 20X2, the adhesive is applied to the ground hair GM and the artificial hair EX. The guiding gap 20X1 facilitates guiding the ground hair GM and the artificial hair EX into the insertion gap 20X2 at the central portion of the bifurcated structure 20 in the Y direction.

[0024] Next, a hair thickening method 100 (FIG. 6) using the adhesive applicator 2 will be described. In the hair thickening method 100, a liquid adhesive is applied to the ground hair GM and the artificial hair EX using the ground hair standing jig 300 together with the adhesive applicator 2, the artificial hair EX is adhered to the ground hair GM, and then the adhesive is cured.

[0025] (Ground hair standing jig) As shown in FIG. 7(A), the ground hair standing jig 300 includes a pressing plate 310 for laying down the surrounding ground hair growing around the target ground hair GM, a standing plate 320 standing up from the pressing plate 310, and a hook member 330 provided at the top of the standing plate 320 and engaging with the ground hair GM. The pressing plate 310 is formed in a rectangular shape, and an opening 310X for inserting the ground hair GM is formed at the central portion thereof. The formation position of the opening 310X only needs to be such that the tip of the target ground hair GM can engage with the top of the standing plate 320. The standing plate 320 is formed in a plate shape and extends in a direction substantially perpendicular to the pressing plate 310. Therefore, the ground hair standing jig 300 has an L-shaped side view. The hook member 330 is preferably provided at the upper part of the standing plate 320. The hook member 330 only needs to be able to engage with the ground hair GM. For example, it is preferable to use a hook-and-loop fastener having a hook portion F as the hook member 330).

[0026] (Artificial hair) As shown in FIG. 7(B), the artificial hair EX includes a plurality of filaments, and the proximal ends of the respective filaments are integrated. The diameter of the filament is not particularly limited, but is preferably 0.1 mm or more and 2 mm or less, and more preferably 0.2 mm or more and 1 mm or less. Further, the length of the filament is not particularly limited, but is preferably 10 mm or more and 30 mm or less. The material of the filament is not particularly limited, and known materials such as plastics can be used. Note that the artificial hair EX may be a single filament.

[0027] (Hair growth method) As shown in FIG. 6, the hair growth method 100 includes an alignment step S110 of aligning the ground hair erecting jig 300, a passing step S120 of passing the ground hair GM through the opening of the ground hair erecting jig 300 (FIG. 7(A)), a placing step S130 of placing the ground hair erecting jig 300 on the head so as to suppress the surrounding ground hair growing around the ground hair GM, an erecting step S140 of erecting the ground hair GM, a temporary fixing step S150 of temporarily fixing the artificial hair EX to the ground hair GM using a temporary fixing agent, an adhesive holding step S160 of causing the adhesive applicator 2 to hold the adhesive, an inserting step S170 of inserting the temporarily fixed ground hair GM and artificial hair EX into the gap 20X of the adhesive applicator 2, a feeding step S180 of feeding the adhesive applicator 2 along the ground hair GM and artificial hair EX, a returning step S190 of returning the adhesive applicator 2 along the ground hair GM and artificial hair EX, and a curing step S200 of curing the adhesive applied to the ground hair GM and artificial hair EX.

[0028] (Alignment step) As shown in FIG. 7(A), in the alignment step S110, the ground hair erecting jig 300 on the head is aligned so that the opening overlaps the target ground hair GM.

[0029] (Passing step) In the passing step S120, the target ground hair GM is passed through the opening. Note that the passing step S120 may be performed after the placing step S130, but is preferably performed before the placing step S130 in terms of workability.

[0030] (Placement Step) In the placement step S130, the hair standing jig 300 is placed at the position set in the alignment step S110. As a result, with the target hair GM passing through the opening, the surrounding hair growing around the hair GM can be laid down. Also, a hairpin is inserted through the horizontal slit SL to sandwich the pressing plate 310 and the surrounding hair. Thus, since the hair standing jig 300 is fixed from the head portion, it is possible to improve the work efficiency and prevent the hair standing jig 300 from falling off.

[0031] (Standing-up Step) In the standing-up step S140, the tip of the hair GM is placed on the top of the standing-up plate 320. As a result, since the tip of the hair GM engages with the standing-up plate 320, the hair GM stands up. At this time, by engaging the tip of the hair GM with the hook member 330, it becomes possible to position the tip of the hair GM in the Y direction. As a result, since the tip of the hair GM does not move inadvertently, the posture of the hair GM is stabilized, and the work efficiency after the temporary fixing step S150 is improved.

[0032] (Temporary Fixing Step) In the temporary fixing step S150, a temporary fixing agent is applied to the base end portion of the artificial hair EX. First, the temporary fixing agent is placed on the sheet. Next, the side surface of the base end portion of the artificial hair EX is brought into contact with the temporary fixing agent on the sheet. As a result, the temporary fixing agent KS is applied to the side surface of the base end portion of the artificial hair EX (Fig. 8(A)). Note that the method of applying the temporary fixing agent to the artificial hair EX is not limited to the above-described method, and known tools such as a brush may be used. Thereafter, in the temporary fixing step S150, the base end portion of the artificial hair EX to which the temporary fixing agent KS has been applied is brought into contact with the side surface of the hair GM (Fig. 8(B)). As a result, the artificial hair EX is temporarily fixed to the hair GM. In the temporarily fixed state, it is preferable that the base end portion of the artificial hair EX is at a height slightly separated from the head portion. Also, at this time, it is preferable that the base end portion of the hair GM and the base end portion of the artificial hair EX are arranged to be substantially parallel.

[0033] (Adhesive holding step) In the adhesive holding step S160, a liquid adhesive AD is applied to the first adhesive holding member 21 and the second adhesive holding member 22. As a result, the liquid adhesive AD is held in the gap 20X between the first adhesive holding member 21 and the second adhesive holding member 22, together with the first adhesive holding member 21 and the second adhesive holding member 22 (FIG. 9(A)).

[0034] (Insertion step) In the insertion step S170, the gap 20X holding the liquid adhesive AD is inserted with respect to the insertion start position IS set for the temporarily fixed ground hair GM and artificial hair EX (FIG. 9(B)). The insertion start position IS is preferably set between the artificial hair EX and the head (FIG. 8(B)). Thereby, the step between the lower end portion (the end portion on the head side) of the ground hair GM and the artificial hair EX can be smoothed.

[0035] (Feeding step) In the feeding step S180, the adhesive applicator 2 is moved along the temporarily fixed ground hair GM and artificial hair EX. During this movement, the state in which the temporarily fixed ground hair GM and artificial hair EX are inserted into the gap 20X holding the liquid adhesive AD is maintained. The feeding step S180 is performed until the gap 20X holding the liquid adhesive AD reaches from the insertion start position IS to the feeding completion position IE. Here, the feeding completion position IE is preferably set above (opposite to the head side) the portion GX temporarily fixed between the ground hair GM and the artificial hair EX by the temporary fixing agent KS (FIG. 8(B)). Thereby, the entire portion GX temporarily fixed by the temporary fixing agent KS between the ground hair GM and the artificial hair EX can be covered with the adhesive (FIG. 2).

[0036] (Return step) In the return step S180, the adhesive applicator 2 is moved along the temporarily fixed natural hair GM and artificial hair EX. The feeding step S180 is performed until the gap 20X holding the liquid adhesive AD reaches the insertion start position IS from the feeding completion position IE. After the insertion start position IS reaches the adhesive applicator 2, the natural hair GM and artificial hair EX are removed from the gap 20X holding the liquid adhesive AD (Fig. 9(C)). Thereby, the entire temporarily fixed portion GX can be covered with the adhesive (Fig. 2).

[0037] Note that, as shown in the figure, in the first adhesive holding member 21 and the second adhesive holding member 22 from the insertion step S170 to the return step S190 (the two-dot chain line in Fig. 8(B)), it is preferable that the tip portions of the first adhesive holding member 21 and the second adhesive holding member 22 are closer to the head side than the base end portions.

[0038] (Adhesive curing step) In the adhesive curing step S200, predetermined light is applied to the applied adhesive using a light source. As the light source, for example, a UV (ultraviolet) lamp, a UV-LED, a visible light LED, an infrared lamp, or the like is provided.

[0039] (Temporary fixing agent) As the temporary fixing agent, a cyanoacrylate-based temporary fixing agent can be used. The cyanoacrylate-based temporary fixing agent contains a component represented by the following formula. CH2=C(CN)COOR (In the formula, R is selected from an alkyl group, an alkoxyalkyl group, a cycloalkyl group, a haloalkyl group, an alkenyl group, an alkynyl group, an arylalkyl group, and an aryl group)

From the viewpoint of handling, visible light rays (wavelength range: 360 nm or more and 830 nm or less) are preferable.

[0051] When applying predetermined light to the applied adhesive, in order to block the light heading towards the scalp, it is preferable that the suppressing plate 310 has light-shielding properties with respect to the wavelength of the light.

[0052] According to the present invention, the gap 20X formed in the bifurcated structure 20 can hold the adhesive AD and allows the natural hair GM and the artificial hair EX to be inserted. Therefore, the entire range of the temporarily fixed portion GX of the natural hair GM and the artificial hair EX can be covered with the adhesive.
