Description

Hair extensions

The present invention relates to a hair extension (fixed hair) attached to the ground hair for the purpose of giving the hair a sense of volume.

As a conventional hair extension, a metal tube is attached to the base end of the bundle of hair to be added, and the ground hair is inserted into the metal tube to crush the tube to crush the ground hair. What to wear is known. In addition, a heat-shrinkable tube is coated on the outside of the tubular body consisting of a bundle of hair impregnated with an adhesive, and the heat-shrinkable tube is heated with an iron etc. while the ground hair is inserted inside the tubular body. By doing so, a device that is attached to the ground hair by a contracted tube and a melted adhesive has been developed (Patent Document 1).

Furthermore, in recent years, a double-sided adhesive tape is used to adhere to the ground hair so that it can be easily attached to the hair in a shorter time. The other surface of which is adhered to the ground hair) has also been developed (Patent Document 2).

JP, 2008-202199, A Utility model registration No. 3198852

However, as in Patent Document 2, a hair extension that uses double-sided adhesive tape to adhere to the ground hair can be attached to the hair (ground hair) very easily, but from the gap between the adhered hair. Since the double-sided adhesive tape can be seen, there is a problem that other people can instantly understand that it is attached to the hair. Further, there is also a problem that the ground hair sticks to the double-sided adhesive tape through the gap between the adhered hair.

An object of the present invention is to solve the problems of the conventional hair extension, to attach it to the hair (ground hair) very easily, and to make it difficult for others to understand that it is attached to the hair. To provide a practical hair extension.

Among the present invention, the invention described in claim 1 is a hair extension in which an adhesive means for attaching the hair bundle to the ground hair is provided at the base end of the hair bundle, and the first hair Is fixed below the inner surface of the substantially rectangular plate-shaped base member with the tips of the hair protruding downward, and the second bundle of hair is located above the inner surface of the base member. It is characterized in that it is fixed in a state where the hair tips are projected upward, and is folded back at the upper edge of the base member so that the hair tips are hung downward.

The invention described in claim 2 is characterized in that, in the invention described in claim 1, the base member has the same color as the second bundle of hairs.

The invention described in claim 3 is the invention described in

claim

1 or 2, wherein the inner surface of the base member has adhesiveness, and the first bundle of hair and the second The hair bundle is adhered to the inner surface of the base member.

The hair extension according to claim 1 can be attached to the hair very easily in a very short time by using an adhesive means, and the second bundle of the hair, together with the base member, has the double-sided adhesive tape on the outside. Since the double-sided adhesive tape is hard to see from the outside, it is hard for other people to understand that it is attached. Further, unlike the conventional hair extension, the situation in which the ground hair sticks to the double-sided adhesive tape through the gap between the adhered hairs does not occur at all.

Since the base member has the same color as the second bundle of hairs and the double-sided adhesive tape is extremely difficult to recognize from the outside, the hair extension according to claim 2 is attached. It is harder for other people to understand.

In the hair extension according to claim 3, the first hair bundle and the second hair bundle are adhered to the inner surface of the base member, and the adhesive means is attached to the inner side (ground hair attachment side) of the first hair bundle and the second hair bundle. Very easy to manufacture.

It shows the state of being adhered to the hair). It is explanatory drawing (the figure which looked at the hair from the upper part) which shows the state which attached the hair extension to the hair (ground hair).

An embodiment of the hair extension according to the present invention will be described in detail below with reference to the drawings.

<Structure of hair extension>
1 and 2 show the appearance of a hair extension according to the present invention and how the hair extension is attached to the hair (ground hair). The hair extension 1 is a base member 2 and a first hair. Bundle (aggregate) H ₁ , a second bundle of hair (aggregate) H ₂ , double-sided adhesive tape 3, and release paper (release paper) 4.

The base member 2 is formed of a synthetic resin (polyester resin) sheet colored in black and having a thickness of about 1.0 mm to have a rectangular shape with a width of about 7.0 mm and a height of about 6.0 mm. Synthetic resin (acrylic) having viscosity is provided on the surface on the side on which the hair is attached, the surface on the right side in FIG. Adhesive made of (resin) is laminated. In addition, the outer surface is subjected to an embossing process (a roughening process such as a matting process) by an etching process, so that it is unwelcome even when irradiated with light.

The first hair bundle H ₁ is adhered to the inner surface of the base member 2 slightly below the center thereof so as to project downward. Each of the hairs h, h,... Constituting the first hair bundle H ₁ has its base end positioned approximately 2.5 mm above the lower end edge of the base member 2 so that the base end portions are substantially parallel to each other. It has been placed.

Further, a second bundle of hair H ₂ is adhered to the upper side of the center of the inner surface of the base member 2 so as to project upward. Each of the hairs h, h,... Constituting the _second bundle of hairs H ₂ has its base end positioned approximately 2.5 mm below the upper end edge of the base member 2 so that the base end portions are substantially parallel. It has been placed in the. Therefore, between the proximal ends of the hairs h, h,... Constituting the first hair bundle H ₁ and the proximal ends of the hairs h, h,... Constituting the second hair bundle H ₂ Has a gap of about 1.0 mm formed. Each of the hairs h, h,... Constituting the _second bundle of hairs H ₂ adhered to the inner surface of the base member 2 is folded back at the upper edge of the base member 2 and droops downward on the tip side. Thus, the folded-back portion is in a state of being attached (bonded) to the outer surface of the base member 2 with an adhesive (having polyurethane-based resin as a main component).

Further, the double-sided adhesive tape 3 is adhered to the outside of the first hair bundle H ₁ and the second hair bundle H ₂ that are adhered to the inner surface of the base member 2 as described above. The double-sided adhesive tape 3 is a film in which a synthetic resin (polyester) film having a thickness of about 50 μm is laminated with a viscous synthetic resin (acrylic resin) adhesive on both sides, and is the same as the base member 2. It is cut into a size (rectangular shape with a width of about 7.0 mm and a height of about 6.0 mm). A release paper (release paper) 4 having the same size as that of the double-sided adhesive tape 3 is adhered to the inside of the double-sided adhesive tape 3 (the side attached to the ground hair, the right side in FIG. 2).

<Hair extension manufacturing method>
FIG. 3 shows an example of a method for manufacturing the hair extension 1 configured as described above. When manufacturing the hair extension 1, first, the first hair bundle H ₁ and the second hair bundle H ₂ are arranged so as to be orthogonal to the longitudinal direction of the base member 2a, and The linearly aligned edges of the hair bundle H _{1 and} the linearly aligned edges of the second hair bundle H ₂ are parallel to each other with a predetermined gap (about 1.0 mm). Place them facing each other. The first bundle of hair H ₁ and the second bundle of hair H ₂ are arranged flatly with respect to the sorting yarns (one or a plurality of yarns) N arranged orthogonally. It is in a state in which it is divided into upper and lower parts by a substantially constant number. Then, the base member 2a (the inner surface and the outer surface) is provided on the upper surfaces of the edge-edge portion of the first hair bundle H _{1 and} the edge-edge portion of the second hair bundle H ₂ that are arranged above and below. Which are viscous) are attached so as to be orthogonal to each other (FIG. 3A).

Next, the first hair bundle H ₁ and the second hair bundle H ₂ thus attached to the base member 2a are inverted (turned over), and the edges of the first hair bundle H ₁ are closed. of the portion and a second upper surface of the edge during portions of the bundle of H ₂ hair attached to be orthogonal to double-sided adhesive tape 3 (Figure 3 (b)). Furthermore, after removing the sorting thread N from the first hair bundle H ₁ and the second hair bundle H ₂ , the first hair bundle H ₁ and the first hair bundle H ₁ attached to the base member 2 a and the double-sided adhesive tape 3 are removed. second after the hair was bundle H ₂ to be inverted again (everted), second bundles of H ₂ hair, folded downward when the upper edge of the base member 2a, a base member 2a a portion of that time aliasing Affix to the outer surface of the (FIG. 3(c)).

After that, the first hair bundle H ₁ and the second hair bundle H ₂ attached to the base member 2a and the double-sided adhesive tape 3 are inverted again (inside out), and the first hair bundle H ₁ A release paper (release paper) 4 is attached to the outer surface of the double-sided pressure-sensitive adhesive tape 3 located outside the edge portion and the edge portion of the second hair bundle H ₂ (FIG. 3D). Then, the production of the hair extension 1 is completed by cutting the base member 2a and the double-sided adhesive tape 3 which are protruding to the outside of the first hair bundle H ₁ and the second hair bundle H ₂ .

<How to use hair extensions>
4 and 5 show a method of attaching the hair extension 1 to the hair (ground hair). When the hair extension 1 is attached to the hair, the hair extension 1 is on the surface layer of the ground hair (parietal hair). The thing inside the ground hair (those that grow from the middle height position of the head) is exposed by lifting up (those that grow from the vicinity) upward. Then, as shown in FIG. 4B, the release paper 4 of the hair extension 1 is peeled off to expose the double-sided adhesive tape 3. Then, as shown in FIG. 4C, the hair extension 1 is attached by adhering the adhesive surface of the double-sided adhesive tape 3 to the bundle of ground hair (bundle of ground hair inside) G. Then, the desired number of

hair extensions

1, 1,... Are placed at approximately the same height position on the hair and are evenly spaced along the lateral direction (width direction) and adhered to the bundle G of ground hair by the above-described method. (See FIG. 5). After a while. The thing in the surface layer of the ground hair which has been lifted is hung down as it was.

In the hair extension 1 mounted on the ground hair as described above, the base member 2 of the same color (black) as the ground hair is located outside the double-sided adhesive tape 3 (on the side opposite to the ground hair that is the mounted body). At the same time, since the base member 2 is covered with the hairs h, h... Of the _second bundle of hairs H ₂ from the outside, the double-sided adhesive tape 3 is almost invisible from the outside. Therefore, other people cannot recognize that the

hair extensions

1, 1... Are attached to the hair at all.

<Effect of hair extension>
In the hair extension 1, as described above, the first hair bundle H ₁ is fixed below the inner surface of the substantially rectangular plate-shaped base member 2 with the tips of the hairs protruding downward, The second hair bundle H ₂ is fixed above the inner surface of the base member 2 with the hair tips protruding upward, and is folded back at the upper edge of the base member 2 to move the hair tips downward. It is in a state of hanging. Therefore, the hair extension 1 can be attached to the hair very easily within a very short time by using the double-sided adhesive tape 3 which is an adhesive means, and the second bundle of hair H ₂ can be attached to the base member 2. At the same time, since the double-sided adhesive tape 3 is covered from the outside, it is difficult to see the double-sided adhesive tape 3 from the outside, and it is difficult for others to understand that it is attached. Further, unlike the conventional hair extension, the situation that the ground hair sticks to the double-sided adhesive tape 3 through the gap between the adhered hairs does not occur.

Further, the hair extension 1 has the base member 2 having the same color (black) as the second hair bundle H ₂ and the double-sided adhesive tape 3 is very difficult to recognize from the outside. It is harder for others to realize that you are there.

Further, since the hair extension 1 has a structure in which the first hair bundle H ₁ and the second hair bundle H ₂ are adhered to the inner adhesive surface of the base member 2, the inner surface of the base member 2 is manufactured at the time of manufacture. The first bundle of hair H ₁ and the second bundle of hair H ₂ are adhered to each other, and the double-sided adhesive tape 3 is attached to the inside thereof (the side on which the ground hair is attached), which enables extremely easy manufacture. ..

In addition, in the hair extension 1, the portion (the portion located on the outer surface of the base member 2) when the hairs h, h,... Composing the _second bundle of hairs H ₂ are folded back is fixed to the base member 2 by an adhesive. Since the base member 2 is attached (bonded) to the outer surface, the base member 2 is hard to see even when the wearer moves violently, and thus it is extremely difficult for others to understand that the wearer is wearing the base member.

<Example of changing hair extensions>
The hair extension according to the present invention is not limited to the one in which the base member is black as in the above-described embodiment, and the base member may be colored in a color other than black or uncolored. For example, when the hair extension according to the present invention is to be attached to brown or gold ground hair, the first bundle of hair H ₁ and the second hair of the second hair are matched with the colors of the ground hair. It is also possible that the bundle H ₂ and the base member are brown or gold.

Further, the hair extension according to the present invention is not limited to the one in which the base material of the double-sided adhesive tape is a synthetic resin film as in the above-mentioned embodiment, and may be changed to one in which the base material of the double-sided adhesive tape is paper. Is also possible. When the base material of the double-sided pressure-sensitive adhesive tape is a synthetic resin film as in the above-described embodiment, there is an advantage that the double-sided pressure-sensitive adhesive tape is not easily torn when the hair is washed while being attached.

Furthermore, the hair extension according to the present invention is not limited to the one in which the adhesive of the base member and the adhesive of the double-sided adhesive tape are adhesives made of an acrylic resin, as in the above embodiment, and a rubber-based adhesive, It is also possible to change to a pressure sensitive adhesive made of a resin other than an acrylic resin such as a pressure sensitive adhesive made of a silicone type resin. When the adhesive of the base member and the adhesive of the double-sided adhesive tape are adhesives made of acrylic resin as in the above embodiment, wash the hair with a surfactant (shampoo etc.) in the mounted state. However, there is an advantage in that the adhesive force is hard to drop (that is, the first hair bundle and the second hair bundle are difficult to remove and the hair is hardly peeled from the ground hair).

In addition, the manner in which the plurality of hair extensions are attached is not limited to the manner in which the hair is placed at substantially the same height position of the hair and is attached at equal intervals along the lateral direction (width direction) as in the above embodiment. It can be appropriately changed according to the volume of hair and the desired hairstyle.

On the other hand, the method for producing a hair extension according to the present invention is not limited to the method of attaching the double-sided adhesive tape after attaching the base member to the first hair bundle and the second hair bundle as in the above embodiment. Instead, it is also possible to change the first hair bundle and the second hair bundle by attaching the double-sided adhesive tape and then attaching the base member. In addition, the method of manufacturing the hair extension according to the present invention is limited to the method of sticking the first bundle of hairs and the second bundle of hairs to the long base member or the double-sided adhesive tape as in the above embodiment. Instead, the base member and/or the double-sided pressure-sensitive adhesive tape, which is cut in advance to a required length, may be changed to one in which the first bundle of hairs and the second bundle of hairs are attached.

Since the hair extension of the present invention has excellent effects as described above, it can be suitably used as a member for increasing the volume of ground hair.
