Description

The present invention relates to a hair extension (hair extension) to be attached to the ground hair for the purpose of giving a voluminous feeling to the hair. Furthermore, it relates to a vein-like extension having a vein-like appearance.

As a conventional extension, a metal tube is attached to the base end of the bundle of hair to be added, and it is attached to the hair by crushing the tube with the hair inserted inside the metal tube. What to do is known. In addition, a heat-shrinkable tube is coated on the outside of a tubular body made of a bundle of hair impregnated with an adhesive, and the heat-shrinkable tube is heated with an iron or the like with the hair inserted inside the tubular body. By doing so, a shrinkable tube and a melted adhesive have been developed to be attached to the hair.

Patent Document 1 states, "It can be attached to the hair very easily without damaging the hair, and it is difficult to remove the hair because of its high binding force, and it gives a feeling of strangeness to the user even when lying down. With the object of "providing a practical extension that does not exist", "extension 1 is a string-like body 3 which is a means of attaching to the hair, and a knot is formed at one end, and the knot (lump shape) is formed. The portion 7) is embedded in the hair of the main body portion 2 and adhered to the main body portion 2 together with the hair with a binder. Further, the string-shaped body 3 is pulled in a direction in which the base end and the tip are separated from each other. The first loop 5a and the second loop 5b contracted by the hair are formed so as to be located at a distance of about 2.0 mm. ”Extension (Patent Document 1: Name of Invention) is disclosed.

Japanese Unexamined Patent Publication No. 2011-236541

The extension according to Patent Document 1 (Patent Document 1: the name of the invention) is fixed to the main body 2 by embedding a knot (lumpy portion 7) in the hair of the main body 2 and adhering it together with the hair with a binder. In short, a plurality of human hairs are bundled in the same direction, and the portion having a length of 10 mm at the base end of the bundle is integrated by bonding with a binder (so-called keratin bond) containing heat-resistant keratin as a main component. Because the artificial hairs are tied together, the positions of the starting points of the artificial hairs are arranged side by side, so that it seems that the hairs are artificially increased. That is, the extension according to Patent Document 1 is the original hairs. Does not seem to grow naturally on the human head.

An object of the present invention is that it is not necessary to fix the adhesive to the natural hair, and it is not necessary to use the adhesive at all in the manufacturing process, so that the hair can be efficiently manufactured and the starting point of the artificial hair can be produced. The position can be dispersed so that it can be worn to make it look natural (ie, it can make the original hair look like it grows naturally on the human head). Is to provide.

In order to solve the above problem, the invention according to claim 1 is an extension in which the attachment means for attaching to the ground hair is a string-like body, and a plurality of extensions are provided near one end of the string-like body. It is characterized in that it is formed by connecting a plurality of hair bundles, which are bundled hairs, with a predetermined length. The hair in the present specification may be human hair or artificial hair such as fiber.

The invention according to claim 2 is the invention according to claim 1, wherein the number of hairs constituting the hair bundle is 3 to 5, and the length of the hair bundle is 30 cm to 50 cm. The predetermined length between the hair bundles is 0.1 mm to 0.2 mm.

The invention according to claim 3 is the invention according to claim 1 or 2, so that the hair bundle forms a knot with the string-like body substantially at the center in the longitudinal direction. It is characterized in that it is movably connected to the string-shaped body along the longitudinal direction of the string-shaped body.

The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the plurality of hair bundles are left and right from the string-like body along the longitudinal direction of the string-like body. It is characterized in that it is in a state of being alternately projected.

The leaf vein-shaped extension described in the present invention is a conventional mounting method (a method of using a sheet-shaped seal, a method of knitting into the root of the hair, a method of mounting using ultrasonic waves, a small tubular bead, etc. Unlike the method of passing the hair together with the hair and fixing it with a pliers, etc.), the mounting means for mounting on the hair is an extension that is a string-like body. Therefore, it can be attached to the hair very easily without damaging the hair, and it is difficult to remove the hair because of its high binding force, and it is practical that the user does not feel uncomfortable even when lying down. Extensions can be provided.

In addition, the leaf vein-like extension according to the present invention is formed by connecting a hair bundle in which a plurality of hairs are bundled to each of the string-like bodies at a predetermined length at one end side. The extension according to Patent Document 1 is formed by bundling about 300 human hairs having a length of about 300 mm, and is integrated by adhering a portion having a length of about 10 mm at the base end of the bundle with a binder. Since the hairs are formed together in one place, the base ends of many hairs are aligned laterally (in one place) at the time of wearing, which makes it unnatural. On the other hand, in the leaf vein-shaped extension according to the present invention, since the base end of the hair is at a different position when the hair is attached, a state close to the state where the hair is growing from the skin is created, and therefore the state of the hair when the hair is attached. Can be made to feel more natural.

It is the whole view and the partial enlarged view of the vein-like extension. It is explanatory drawing which shows the manufacturing method of the vein-like extension. It is an overall view before attachment of a vein-like extension. It is explanatory drawing which shows the state which attached the leaf vein-like extension to the hair.

<Structure of leaf vein extension and manufacturing method>
Hereinafter, an embodiment of the vein-shaped extension 1 according to the present invention will be described in detail with reference to FIGS. 1 to 4. FIG. 1 is an overall view and a partially enlarged view of the vein-shaped extension 1 according to the present invention.

As described in FIG. 1, the leaf vein-shaped extension 1 according to the present invention bundles and binds a plurality of hairs 3 to each portion separated by a predetermined length on one end side of the string-like body 2. It is a leaf vein-like extension 1 that is characterized by being formed and looks like a leaf vein (a muscle of the vascular system running on the leaf surface).

As shown in the enlarged view of FIG. 1, a plurality of hairs 3 (human hair may be used, or artificial hair such as fiber) may be used for each of the string-shaped bodies 2 with a predetermined length separated from each other. It is tied together (may be present) (how to tie it will be explained later). The predetermined length (distance between the center of a knot and the center of the adjacent knot) is usually 1 mm or less, but if desired, the interval can be 1 mm or more, and the width of the interval is random (0. It can also be set to 5 mm to 1.5 mm). The number of the plurality of hairs 3 forming one knot 4 is 3 to 5, and the length of the hairs 3 is 30 cm to 50 cm. The knot 4 generated when the hair 3 is tied to the string-like body 2 is tied so as to be substantially in the center of the hair 3 and movably along the string-like body 2. Further, as described in FIG. 1, the hair 3 is flowed around the string-like body 2 so as to spread alternately to the left and right at each knot 4.

FIG. 2 is an explanatory view showing a method for producing the leaf vein-shaped extension 1 (that is, an explanatory view showing a method for connecting the hair 3 to the string-like body 2 of the leaf vein-shaped extension 1). In this specification, for convenience of explanation, it is inevitable that the expression is two-dimensional, but the actual work is performed in the three-dimensional space.

First, as shown in FIG. 2A, the hair 3 (a bundle of 3 to 5 hairs) is set under the string-like body 2 in a state of being folded back once. When viewed from the tip of the fold, the tip on the right side of the hair 3 is (α), the tip on the left side of the hair 3 is (β), and the tip of the fold is (γ). The tying work is started from this state.

Then, as described in FIG. 2B, the right end (α) of the hair 3 is passed from the lower side to the upper side of the string-like body 2, and the left end (β) of the hair 3 is string-shaped. Pass from the lower side to the upper side of the body 2, pass the lower side of (γ), then fold back (described as γ') and pass under (γ) again to pass the upper side of the string-shaped body 2. Let it pass.

Further, as described in FIG. 2C, the right tip (α) of the hair 3 is passed between (γ) and (γ'). By pulling both ends of αβ, a knot is finally formed as shown in FIG. 2D, and one tying operation is completed. When actually producing the leaf vein-shaped extension 1, this work is repeated many times. That is, this step is repeated about 10 to 30 times at the positions adjacent to each other along the string-shaped body 2. After the hair 3 is tied to the string-shaped body 2, the position of the knot 4 is freely moved along the string-shaped body 2 and tied to one end side of the string-shaped body 2.

<How to use leaf vein extension>
FIG. 3 is an overall view of the vein-shaped extension 1 before attachment. The leaf vein-shaped extension 1 is formed by placing a predetermined length on one end side of the string-like body 2 and bundling and connecting a plurality of hairs 3 to each of them. As described in FIG. 3, on the other end side of the string-like body 2, a knob 5 having an inner circumference of about 90 mm for inserting a finger when pulling the string-like body 2 binds the string-like body 2. Is formed by.

Then, the first loop 6 and the second loop 7 that contract by pulling the base end and the tip end of the string-shaped body 2 in a direction that separates them by binding the string-shaped body 2 are positioned at predetermined distances from each other. It is formed to do. The string-like body 2 is formed of fibers having a thickness of 53d to 10,630d mainly composed of cotton, and the inner circumferences of the first loop 6 and the second loop 7 have a length of 5.0 mm to 13 It is adjusted to be 0.0 mm.

FIG. 4 is an explanatory view showing a state in which the vein-shaped extension 1 is attached to the hair H. When the leaf vein-shaped extension 1 is attached to the ground hair H (that is, the user's own hair), a predetermined amount (about 50 hairs) of the ground hair H, H ... Is bundled and the inside of the second loop 7 is filled. After the insertion, the inside of the first loop 6 is inserted (see FIG. 4). In addition, when the ground hairs H, H ... Are inserted into the second loop 7 and the first loop 6 in this way, a tool such as a crochet can be preferably used.

After that, while grasping the base end on one end side of the string-shaped body 2, the knob 5 of the string-shaped body 3 is pulled outward. When the string-like body 2 is pulled in this way, the first loop 6 and the second loop 7 are twisted so as to rotate relatively with a slight increase in distance, and the first loop 6 and the second loop 7 are twisted. (That is, the first loop 6 and the second loop 7 contract (see FIG. 4)).

When the first loop 6 and the second loop 7 contract while twisting each other in this way, the ground hairs H, H ... Create a spiral of about 180 degrees between the first loop 6 and the second loop 7. It is gripped by the first loop 6 and the second loop 7 in a state of being bent according to the unevenness (unevenness formed by binding) of the string-shaped body 2 while drawing. Therefore, the ground hairs H, H ... Inserted in the first loop 6 and the second loop 7 are gripped with an extremely high binding force.

Then, as described above, after the ground hairs H, H ... Are gripped by the first loop 6 and the second loop 7 of the string-like body 2, the outer side of the contracted first loop 5a and the second loop 5b. Then, the attachment to the hair is completed by cutting the string-like body 2.

<Effect of leaf vein extension>
Conventional extensions can be roughly divided into methods for attaching extensions, such as weaving into the hair, sheet-like extensions that use a sheet-like seal on the hair to attach the extension, diameter 3 mm to 5 mm, and length 5 mm to 15 mm. In some cases, the hair and the extension are passed through the heat-shrinkable tube together, and the extension is attached to the heat-shrinkable tube and the extension by using the heat of a hair iron or the like.

Since the braided extension has stitches, the braided part is inevitably bumpy, which makes the mounting part feel uncomfortable. The seal extension does not have a lumpy feel, but when you remove it, you have to use a special remover or a nail polish remover that contains acetone, which may damage the skin. There is also a problem that the mounting strength is weak. In addition, the ingredients contained in shampoos and treatments and the oil content of the skin also weaken the adhesive part. In addition, it is also sensitive to heat, which limits hair dryers and curling irons.

The leaf vein-shaped extension 1 according to the present invention is a fundamental review of these conventional methods, and is epoch-making in that it has sufficient strength and does not cause discomfort despite being easy to wear. It is an extension. That is, the leaf vein-shaped extension 1 is formed by bundling and connecting a plurality of hairs 3 to each of the string-shaped bodies 2 at a predetermined length at one end side. The extension according to Patent Document 1 is formed by bundling about 300 human hairs having a length of about 300 mm, and is integrated by adhering a portion having a length of about 10 mm at the base end of the bundle with a binder. However, since the hair 3 is formed in one place in this extension, the base ends of many hairs are aligned laterally (in one place) when worn, and it is undeniable that it feels unnatural. .. On the other hand, in the leaf vein-shaped extension 1 according to the present invention, since the base ends of the hairs (each hair bundle) 3 are at different positions when worn, a state close to the state in which hairs are growing from the skin is created. The condition of the hair when worn becomes more natural.

<Example of extension change>
The leaf vein-shaped extension according to the present invention is not limited to the aspects of the above-described embodiments, and the configuration of the string-like body, hair, knot, etc. is not deviated from the gist of the present invention. Can be changed as appropriate.

Since the leaf vein-like extension according to the present invention exerts an excellent effect as described above, it can be suitably used as a so-called hair extension for giving volume to the hair.
