DETAILED DESCRIPTION OF THE INVENTION

[0009] Embodiment 1 Fig. 1 is a diagram showing the configuration of a hair extension according to embodiment 1. Figs. 2A and 2B are diagrams showing a method for manufacturing a hair group portion of the hair extension shown in Fig. 1.

Figure 10 is a photograph of the hair extension shown in Figure 1.

[0011] The hair extension 1 of the present application is used by being attached to hair. In each drawing, the number of hairs constituting the hair extension 1 is shown in each drawing as fewer than the actual number for ease of understanding. As shown in FIG. 1, the longitudinal direction of the hair extension 1 is referred to as the longitudinal direction X, and the side of the longitudinal direction X of the hair extension 1 that is attached to hair is referred to as the end side X1, and the opposite side is referred to as the start side X2. Therefore, each part of the hair extension 1 will be described using these directions as a reference.

[0012] As shown in FIG. 1, the hair extension 1 comprises a base portion 2, an initial portion 3, a terminal portion 4, a hair group portion 5, and a wound portion 6. The base portion 2 is formed from a folded second string-like member 20 (see FIG. 5A), and has a loop portion 21 on the terminal end side X1. Here, the base portion 2 is formed from a single second string-like member 20. The second string-like member 20 has a diameter of about 0.3 mm in its natural state without any applied force, and is made from cotton.

[0013] The second string-like member 20 is not suitable for use in a hair extension 1 manufacturing method described below, as it involves a step of pulling the second string-like member 20 in the longitudinal direction X. Therefore, a material with excessive elasticity is not suitable. Furthermore, the second string-like member 20 must be strong enough to withstand the pulling step during manufacturing. Furthermore, as the wound portion 6 is formed by winding, as described below, the second string-like member 20 must be strong enough to withstand this. Furthermore, since the second string-like member 20 is used on hair, it must be strong enough to withstand washing and brushing, and must also be heat-resistant enough to withstand the heat of a hair dryer. As long as these requirements are met, materials other than cotton may be used, and it is also possible to form the second string-like member 20 from a material that dries faster than cotton.

[0014] The initial portion 3 is formed on the starting side X2 of the base portion 2 in the longitudinal direction X. The final portion 4 is formed on the ending side X1 of the base portion 2 in the longitudinal direction X. The wound portion 6 and the hair group portion 5 are formed between the initial portion 3 and the ending portion 4 of the base portion 2. The wound portion 6 is fixed by winding one end side of the hair group portion 5 around the base portion 2. Note that the one end side of the hair group portion 5 refers to the same side as the ending side X1 of the hair extension 1 in the longitudinal direction X, so in the following description, the one end side of the hair group portion 5 will also be referred to as the one end side X1. The side opposite the one end side X1 will be referred to as the other end side X2. Therefore, the other end side X2 refers to the same side as the starting end side X2 in the longitudinal direction X.

[0015] An adhesive layer 7 (see FIG. 4B) for fixing the first plurality of hairs 50 is formed on one end side X1 of the hair group portion 5. When configured as a hair extension 1, as shown in FIG. 1, the adhesive layer 7 of the hair group portion 5 is located below the wound portion 6 and is therefore not visible on the surface. Here, the wound portion 6 and the hair group portion 5 are formed continuously in the longitudinal direction X from the initial portion 3 to the final portion 4, with four pairs being formed from the initial portion 3 side: a pair of a first wound portion 61 and a first hair group portion 51, a pair of a second wound portion 62 and a second hair group portion 52, a pair of a third wound portion 63 and a third hair group portion 53, and a pair of a fourth wound portion 64 and a fourth hair group portion 54.

[0016] In the following description, when referring to any or all of these wound portions 61, 62, 63, and 64, they may be referred to as wound portion 6. When referring to any or all of these hair group portions 51, 52, 53, and 54, they may be referred to as hair group portion 5.

[0017] The initial portion 3 is formed adjacent to the starting end side X2 of the first wound portion 61. The final portion 4 is formed adjacent to the terminal end side X1 of the fourth wound portion 64. Therefore, the initial portion 3 and the final portion 4 restrict the movement of the wound portion 6 and the hair group portion 5 in the longitudinal direction X. The initial portion 3, the first wound portion 61, the second wound portion 62, the third wound portion 63, the fourth wound portion 64, and the final portion 4 are formed by a continuous first string-shaped member 10 (see FIG. 5B). Here, they are formed by a single continuous first string-shaped member 10.

[0018] The first string-like member 10 may be made of, for example, the same material as the second string-like member 20, or as another example, it may be made of a rubber string having a diameter of about 0.3 mm in its natural state when no force is applied. Furthermore, since it is used on hair, it must be strong enough to withstand washing and brushing, and must also be heat-resistant enough to withstand the heat of a hair dryer. As long as it meets these requirements, other materials may be used, and it may even be made of a material that dries quickly.

[0019] Here, the structure of one hair group portion 5 before being attached to the base portion 2 will be described with reference to FIG. 4B. As previously described, the hair group portion 5 has an adhesive layer portion 7 formed on one end side X1 of the hair group portion 5 for fixing the first plurality of hairs 50. The first plurality of hairs is, for example, about 120 to 130 hairs. The hairs may be natural hairs, artificial hairs, or both. The adhesive layer portion 7 is formed of a low-temperature curing resin adhesive that cures at, for example, 30 to 40°C. The adhesive layer portion 7 may be any material that can hold the first plurality of hairs 50.

[0020] Furthermore, the adhesive layer 7 needs to have a certain degree of flexibility because it is wound and fixed to the base 2 by the winding portion 6. Furthermore, a thicker adhesive layer 7 is not appropriate because it would increase the size of the winding portion 6, so the adhesive layer 7 is formed to the minimum thickness that can hold the first plurality of hairs 50. This is because, even if the adhesive layer 7 has almost no function of fixing the first plurality of hairs 50 after the winding portion 6 is formed, there is almost no risk of the first plurality of hairs 50 coming off the base 2 due to the winding portion 6.

[0021] Here are specific examples of the size of each portion. As shown in FIG. 1, the length W1 in the longitudinal direction X of the loop portion 21 of the base portion 2 is approximately 4 mm to 5 mm. The length W2 in the longitudinal direction X of the wound portion 6 is approximately 3 mm to 4 mm. As shown in FIG. 4B, the length W3 in the longitudinal direction X of the hair group portion 5 can be any length required for the hair extension 1. For example, a length of approximately 40 cm to 50 cm is considered. The length W4 in the longitudinal direction X of the adhesive layer portion 7 is approximately 3 mm to 4 mm. The width H1 of the adhesive layer portion 7 is approximately 8 mm to 10 mm. Therefore, 120 to 130 hairs as the first plurality are arranged approximately evenly within this width H1.

[0022] In this example, four pairs of winding portions 6 and hair group portions 5 are formed, so the total number of hairs in the hair extension 1 is approximately 500, and the weight of the hair extension 1 can be made very light, at approximately 1 g. Furthermore, the length W3 in the longitudinal direction X of the hair group portion 5 can be cut to the required length after attachment to the hair. Note that each length shown above is an example and can be set as appropriate.

[0023] Furthermore, if the length W1 of the loop portion 21 is shorter than necessary, it will be difficult to attach the hair extension 1. If it is longer than necessary, it will feel uncomfortable when attached to the hair and will be inappropriate. If the length W2 of the winding portion 6 is shorter than necessary, the hair group portion 5 will be more likely to come off the base portion. If it is longer than necessary, it will feel uncomfortable when attached to the hair and will be inappropriate.

[0024] Furthermore, if the length W4 of the adhesive layer portion 7 is made longer than necessary, the adhesive layer portion 7 will protrude from the winding portion 6 when attached to the base 2, resulting in a poor aesthetic appearance. If the length W4 is made shorter than necessary, the hair will not be fixed securely, which may cause the hair to come off the hair group portion 5 when attached to the base 2, so it is necessary to set the length appropriately. Furthermore, the colors of each portion do not have to be black or brown, and can be changed as needed to suit the color of the hair extension 1, such as red, yellow, blue, green, gold, silver, or a mixture of multiple colors.

[0025] Next, a method for manufacturing the hair extension 1 of embodiment 1 configured as described above will be described. First, a method for manufacturing the hair group portion 5 of the hair extension 1 will be described with reference to Figures 2 to 4. On a workbench 8, one end side X1 of a second plurality of hairs 500, which is greater than the first plurality of hairs, is aligned in one direction Y (the same side as the one end side X1 of the hair group portion 5) so as to form approximately a line (Figure 2A).

[0026] At this time, one end side X1 of the second plurality of hairs 500 is placed so as to protrude a preset length from the edge 81 of the work table 8, and at this stage, one end side X1 of the second plurality of hairs 500 varies in the longitudinal direction X. Note that the second plurality, which is greater than the first plurality, is the number required to produce multiple hair group portions 5 at once in the following process, and is the possible number required if approximately 50 to 60 hair group portions 5 are produced in one production run, as described below.

[0027] Next, a predetermined length is left from one end side X1 of the second plurality of hairs 500, and tape 82 is applied in one direction Y from the other end side X2 of the work table 8 beyond the edge 81 to temporarily fix the state of the second plurality of hairs 500 aligned in one direction Y as shown in FIG. 2A (FIG. 2B). Next, one end side X1 of the second plurality of hairs 500 is trimmed in the longitudinal direction X, leaving a portion (FIG. 3A). Here, the one end side X1 of the second plurality of hairs 500 is trimmed using the edge 81 of the work table 8 as a guide, which makes it easy to do.

[0028] Next, adhesive 70 is applied to the trimmed area of ​​one end side X1 of the second plurality of hairs 500, leaving a portion that protrudes beyond the tape 82 (FIG. 3B). Next, for example, the hairs in the state of FIG. 3B are placed in a heater at a temperature of 30 to 40°C for about an hour to harden the adhesive 70 and form the adhesive layer 7. Then, the tape 82 is removed (FIG. 4A). In this way, even after the tape 82 is removed, the adhesive 70 has hardened to form the adhesive layer 7, so that one end side X1 of the second plurality of hairs 500 remains fixed in an aligned state.

[0029] Next, the second plurality of hairs 500 on which the adhesive layer portion 7 is formed are cut in one direction Y at a predetermined width H1 to form a plurality of pre-attached hair group portions 5 (FIG. 4B). Through the steps up to this point, a plurality of pre-attached hair group portions 5 are simply and easily formed on the base 2.

[0030] Next, the portion of the base 2 on the terminal end X1 that will become the loop portion 21 and the starting end X2 of the base 2 are pulled in opposite directions in the longitudinal direction X (FIG. 5A). Next, a bobbin 100 around which a first string-shaped member 10 is wound is prepared. Next, one end of the first string-shaped member 10 is tied to the starting end X2 of the base 2 to create an initial portion 3 (FIG. 5B). Next, a first hair group portion 51 is prepared near the base 2 (FIG. 5C).

[0031] Next, the adhesive layer portion 7 on one end side X1 of the first hair group portion 51 is placed on the terminal end side X1 of the initial portion 3 of the base portion 2 (FIG. 6A). Next, the first string-shaped member 10, which continues from the initial portion 3, is wound around the initial portion 3 from the terminal end side X1 in the longitudinal direction X (FIG. 6B). Furthermore, while moving toward the terminal end side X1, the first string-shaped member 10 is wound around the base portion 2 so as to tighten the adhesive layer portion 7 of the first hair group portion 51, forming a first wound portion 61 (FIG. 6C). This winding operation is performed by rotating the bobbin 100 around the base portion 2 (FIG. 6A → FIG. 6B → FIG. 6C) while applying tension to the base portion 2 in the longitudinal direction X, thereby forming a wound portion 6. The following wound portions 6 are formed in the same manner, and therefore their description will be omitted as appropriate.

[0032] Next, the adhesive layer portion 7 on one end side X1 of the second hair group portion 52 is placed on the terminal side X1 of the initial portion 3 of the base portion 2, which is also the terminal side X1 of the first wound portion 61 (FIG. 7A). Next, the first string-shaped member 10, which is continuous with the initial portion 3 and the first wound portion 61, is moved from the terminal side X1 of the first wound portion 61 to the terminal side X1, and the first string-shaped member 10 is wound around the base portion 2 so as to tighten the adhesive layer portion 7 of the second hair group portion 52, to form the second wound portion 62 (FIG. 7B).

[0033] Next, as in the above case, the adhesive layer portion 7 on one end side X1 of the third hair group portion 53 is placed on the terminal side X1 of the initial portion 3 of the base 2, which is also the terminal side X1 of the second winding portion 62. Next, the first string-shaped member 10, which is continuous with the initial portion 3, first winding portion 61, and second winding portion 62, is wound around the base 2 while moving from the terminal side X1 of the second winding portion 62 to the terminal side X1, thereby tightening the adhesive layer portion 7 of the third hair group portion 53, to form the third winding portion 63.

[0034] Next, as in the above case, the adhesive layer portion 7 on one end side X1 of the fourth hair group portion 54 is placed on the terminal side X1 of the initial portion 3 of the base 2, which is also the terminal side X1 of the third winding portion 63. Next, the first string-shaped member 10, which is continuous with the initial portion 3, first winding portion 61, second winding portion 62, and third winding portion 63, is moved from the terminal side X1 of the third winding portion 63 to the terminal side X1, while winding the first string-shaped member 10 around the base 2 so as to tighten the adhesive layer portion 7 of the fourth hair group portion 54, thereby forming the fourth winding portion 64.

[0035] Next, the first string-like member 10, which is continuous with the initial portion 3, the first winding portion 61, the second winding portion 62, the third winding portion 63, and the fourth winding portion 64, is tied to the base portion 2 on the terminal side X1 of the fourth winding portion 64 to form the terminal portion 4. At the same time, a loop portion 21 is formed on the base portion 2 on the terminal side X1 of the terminal portion 4 (FIG. 7C). Then, the first string-like member 10 is cut on the bobbin 100 side of the terminal portion 4, and the tension on the base portion 2 in the longitudinal direction X is released, completing the hair extension 1 (FIGS. 1 and 10).

[0036] Next, we will explain how to attach the hair extension 1 of embodiment 1 configured and manufactured as described above. First, a portion of the hair growing on the head is separated using a comb or similar tool to prepare a natural hair bundle 9, and the hair extension 1 is prepared nearby (FIG. 8A). Wetting the natural hair bundle 9 at this time will prevent the natural hair bundle 9 from falling apart, making the following attachment process easier. Next, the natural hair bundle 9 is inserted into the loop portion 21 of the hair extension 1 (FIG. 8B). This can be done more easily by using something shaped like a crochet hook, for example.

[0037] Next, the hair extension 1 and the natural hair bundle 9 are tied together to form a knot 91 (Figure 9A). The knot 91 should be formed approximately 10 mm away from the scalp. By separating the knot 91 slightly from the scalp in this way, stress on the scalp can be reduced. Next, an elastic band 92 or the like is wrapped around the top of the knot 91 and tied, and the hair extension 1 is attached to the natural hair bundle 9 and secured in place, thereby attaching the hair extension 1 to the hair (Figure 9B). Securing the hair extension 1 to the natural hair bundle 9 in this way prevents the hair extension 1 from easily coming off the natural hair bundle 9, ensuring that the hair extension 1 is securely attached to the scalp.

[0038] In the first embodiment described above, an example is shown in which there are four pairs of winding portions 6 and hair group portions 5, but this is not limited to this and is merely one example, and the number of pairs of winding portions 6 and hair group portions 5 can be any number equal to or greater than one. Furthermore, when there are a large number of pairs of winding portions 6 and hair group portions 5, it is also possible to create an intermediate retaining portion in the base portion 2 midway between the initial portion 3 and the final portion 4 in the longitudinal direction X in order to strengthen the fixation. The number of pairs of winding portions 6 and hair group portions 5 is set appropriately to an extent that reduces discomfort in the user's daily life while maintaining a natural look of the hair.

So, The hair group can be easily fixed to the base.

[0043] Furthermore, according to the hair extension of the first embodiment configured as described above, The hair group portion is formed such that a portion of the wound portion other than that fixed to the base portion is exposed from a starting end side of the wound portion in the longitudinal direction. So, The hair in the hair group can be easily manipulated.

[0044] Furthermore, according to the hair extension of the first embodiment configured as described above, The base portion is formed by folding back the second string-like member, with the terminal portion formed on the folded back side, and the loop portion formed on the terminal end side of the terminal portion. So, The structure of the base ring portion is simple and can be easily manufactured.

[0045] Furthermore, according to the method for manufacturing a hair extension of the first embodiment configured as described above, a step of pulling the loop portion at the terminal end side of the base portion and the starting end side of the base portion in opposite longitudinal directions; a step of tying one end of the first string-like member to a starting end of the base portion to form the starting portion; a step of placing one end of the hair group portion on the terminal end side of the initial portion of the base, and winding the first string-shaped member continuing from the initial portion while moving it from the starting end side to the terminal end side in the longitudinal direction of the base to form the wound portion; and a step of tying the first string-like member continuing from the wound portion to the base portion on the terminal end side of the wound portion to form a terminal end portion.
