Description

[Technical field]

[0001] The present invention relates to a wig base, a wig, and a method for manufacturing a wig. [Background technology]

[0002] Conventionally, some wig wearers have their own hair remaining, while others have almost no hair, and the size of the wig varies from partial to full head coverage, and many types of wigs have been developed. One of these many types of wigs is a full head wig that can be used even when the wearer has almost no hair remaining on the head. Patent Document 1 proposes a full head wig (wig) that has a non-slip material on the surface of an elastic band to improve the fit when worn and prevent the wig from shifting position.

[0003] [Patent Document 1] JP 2016-156103 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, a wig base that can be used for a full head wig needs to be sewn together to form a three-dimensional shape from multiple base materials, and the joints where the stitching is performed can be uncomfortable for the wearer. Also, if the stitching has a large step, the step will come into contact with and rub against the scalp of the wearer who has little natural hair, and if the irritation to the skin is too strong, it may cause rough skin.

[0005] The present invention has been devised to solve such problems. That is, an object of the present invention is to provide a wig base, a wig, and a method for manufacturing a wig that can reduce the discomfort caused by the joint part of the base material touching the skin. [Means for solving the problem]

[0006] The wig base of the present invention is A wig base constructed by joining two or more base materials at joints, A first base material in which a joining portion located on an inner surface side corresponding to a head side of a wearer is set at an outer edge portion in the joining portion; a second base material having a joining portion set at an outer edge portion thereof, the joining portion overlapping the outer surface side on which the artificial hairs are planted with respect to the joining portion of the first base material; The joint portion of the first base material is configured to have no fold so that a step corresponding to the thickness of the first base material does not occur on the inner surface side of the wig base, The first base material and the second base material are integrated by bonding in a state in which an outer edge forming an outer peripheral portion of the first base material is positioned on the inner surface side and inside the outer edge portion of the second base material, The joint portion is configured so that only a step corresponding to the thickness of the first base material is generated on the inner surface side.

[0007] The wig base of the present invention may be configured such that the joint portion has dot-like adhesive sections arranged in two rows, and includes an area in which the adhesive sections in one row are offset from the adhesive sections in the adjacent row so that they are not adjacent to each other.

[0008] In addition, the base material may have a plurality of regions with different elasticity, including low-stretch regions and high-stretch regions having higher elasticity than the low-stretch regions, and the high-stretch regions are arranged in a high-stretch range of the wig base that is set across the sides to the back of the head, and the high-stretch range may be configured to include an area in which the high-stretch regions of larger sizes are arranged as the wig base approaches the top of the head.

[0009] In addition, the low elasticity region and the high elasticity region may be visually recognized as different colors, and may be configured so that the low elasticity region and the high elasticity region can be distinguished when the wig base is visually recognized, and in the high elasticity range, a plurality of the high elasticity regions configured in an approximately diamond shape are arranged side by side in a circumferential direction continuing from the forehead side through the temporal region to the occipital region, and two vertices located diagonally in the high elasticity region are located on both sides in the circumferential direction, and the remaining two vertices are located on the top side and the lower side corresponding to the outer circumferential edge side of the wig base.

[0010] The wig of the present invention is constructed by implanting artificial hair on the wig base of the present invention.

[0011] The method for manufacturing a wig of the present invention is a method for manufacturing a wig using a wig base of the present invention, and includes a base manufacturing process in which two or more base materials are joined at joints to manufacture a wig base having a non-folded section on at least a portion of the outer peripheral edge of the wig base, and a size adjustment process in which at least a portion of the outer peripheral edge of the wig base manufactured in the base manufacturing process is cut and removed to adjust the size of the wig base. Effect of the Invention

[0012] According to the wig base of the present invention, since there is no need to provide a seam at the joint of the base material, it is possible to reduce the discomfort felt when the joint contacts the head of the wearer. In addition, since the step on the inner side of the joint is limited to only the thickness of the base material, it is possible to reduce the discomfort felt when the joint contacts the head of the wearer. Therefore, it is possible to provide a wig base suitable for a full-head type wig that covers most of the head, and in particular for a medical wig used by a patient undergoing treatment who has little natural hair and is easily affected by irritation to the skin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The wig base of the present invention has no seams at the joints of the base material and the step on the inner surface is small, thereby reducing the discomfort felt when the joints come into contact with the wearer's head.

[0015] A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1(a) is a plan view of a wig base 10, FIG. 1(b) is a side view, and FIG. 2 is a rear view of the wig base. In the following, for ease of understanding, the side of the wig base 10 on which the imitation hair H is provided is the outer side, and the side that contacts the wearer's scalp is the inner side. In addition, in FIG. 1(a), in order to facilitate understanding of the wig base 10, a wig W on which a part of the imitation hair H is implanted is shown, and the illustration of the high elasticity region R2 is omitted. In FIG. 1(b), the head of the wearer is shown by a dashed line for reference, and only the high elasticity region R2 of the left base material 21B is shown, and the illustration of the high elasticity region R2 of the central base material 21A is omitted. In FIG. 2, only the high elasticity region R2 of the central base material 21A is shown, and the illustration of the high elasticity regions R2 of the other base materials 21B and 21C is omitted.

[0016] The wig base 10 can be used for a full-head wig W that covers most of the head, and is made by joining multiple planar base materials 21. Specifically, the wig base 10 is made by combining a central base material 21A with base materials 21B and 21C that are symmetrically configured. The number of base materials 21 that make up the wig base 10 is not limited to three, and two or four or more may be combined, and the shape is not limited to a configuration divided into a center and both left and right sides, and other divided structures may be used.

[0017] The base material 21 is preferably made of a material having elasticity, and preferably has a low elasticity region R1 and a high elasticity region R2 having higher elasticity than the low elasticity region R1. For example, the low elasticity region R1 can be formed by overlapping a nylon mesh layer and a polyester mesh layer, and the high elasticity region R2 can be formed only by a highly elastic nylon mesh layer. Other materials can also be used for the base material 21. The low elasticity region R1 and the high elasticity region R2 of the base material 21 can be set by subjecting the material corresponding to the low elasticity region R1 to a carbonization process in the portion corresponding to the high elasticity region R2.

[0018] Unlike conventional wig sheets, the wig base 10 does not have a net on the inner side, and is used so that the base material 21 directly contacts the wearer. This makes it possible to prevent the wig W from becoming slippery due to the presence of the net when worn by the wearer.

[0019] As shown in FIG. 1 and FIG. 2, the low elasticity region R1 of the wig base 10 is set in a certain range (low elasticity range A1) along a region close to the top of the head and a part of the periphery close to the outer periphery. The high elasticity region R2 is set between the top of the head and the part close to the outer periphery, and is set in a region (high elasticity range A2) of the wig base 10 that spans from the side to the back of the head. In FIG. 2, the high elasticity range A2 is shown by a thin line as a range that continues from the left side of the head to the back of the head. The high elasticity range A2 is configured symmetrically from the left side of the head to the right side of the head. As a result, even if the amount of hair of the wearer changes from a large amount to a small amount, the high elasticity region R2 from the side side to the back side of the wig base 10 is highly elastic and can suitably accommodate the wearer's hair.

[0020] In this way, the wig base 10, which does not use a net and has regions with different elasticity, can provide a wig W that fits snugly over the wearer's entire head without wrinkles and is comfortable to wear with little stress. The wig W with the artificial hair H implanted on the wig base 10 is particularly suitable for patients undergoing treatment such as anti-cancer drug treatment, and can be a wig that is comfortable to wear and looks good even if the amount of hair changes due to treatment.

[0021] Next, the configuration of the wig base 10 using a plurality of base materials 21 will be described in more detail. In the wig base 10, the high elasticity regions R2 are arranged in a plurality of locations and in a plurality of sizes so as to form the high elasticity range A2 set across the side and the back of the head. Specifically, the high elasticity regions R2 of small size are set on the side close to the outer periphery, and the high elasticity regions R2 of large size are arranged toward the upper side close to the top of the head. This reduces the shape change in the portion close to the outer periphery of the wig base 10, and prevents a sudden change in elasticity at the boundary between the low elasticity range A1 and the high elasticity range A2, which also improves the comfort of wearing.

[0022] The highly elastic region R2 can be configured in various shapes such as polygonal, circular, and elliptical, but is preferably formed in an approximately diamond shape. The approximately diamond-shaped highly elastic regions R2 are arranged in a row in the circumferential direction D1 that continues from the frontal side to the temporal side to the occipital side. The highly elastic region R2 is configured so that two vertices located diagonally are located on both sides of the circumferential direction D1, and the remaining two vertices are located on the top side and the lower side corresponding to the outer periphery side of the wig base 10. By arranging a large number of these approximately diamond-shaped highly elastic regions R2 in multiple rows in the vertical direction D2, in addition to the functionality in the highly elastic range A2, the appearance of the wig base 10 as a single unit can be improved. It is also preferable that the highly elastic region R2 be formed in an approximately diamond shape that is long in the circumferential direction D1 and short in the vertical direction D2.This suppresses deformation in the circumferential direction, while allowing deformation in the vertical direction D2, making it possible to provide a wig base 10 that can easily deform by expanding outward to accommodate hair.

[0023] The wig base 10 has low-elasticity region R1 and high-elasticity region R2 made of different materials and different thicknesses, and a combination of these multiple types of regions can be part of the design of the wig W. It is also preferable to make the high-elasticity region R2 and the low-elasticity region R1 different in color, so that a large number of approximately diamond shapes are lined up on the inner surface of the wig W alone, making it easy for the wearer to understand that the wig W has parts with different elasticity. As for the color, for example, the low-elasticity region R1 can be made to be a skin color close to white, and the high-elasticity region R2 can be made to be a skin color darker than the low-elasticity region R1.

[0024] The base material 21 does not necessarily have to be configured using only two colors, and may use three or more colors. For example, it is also preferable to set a region close to black in a region close to a part of the outer periphery, such as a portion close to the outer periphery on the front side corresponding to the frontal region. This makes it possible to make the boundary with the area with a lot of natural hair less noticeable. The base material 21 using multiple colors can be set by, for example, printing on the base material 21.

[0025] Next, the joint portion of the base material 21 will be described in detail with reference to Fig. 3. Fig. 3 shows the joint portion of the base material 21, where Fig. 3(a) is a plan view of the wig base 10, Fig. 3(b) is an enlarged view of a part of the joint portion of Fig. 3(a) (the range of the dashed dotted line in Fig. 3(a)), and Fig. 3(c) is a cross-sectional view taken along line AA in Fig. 3(b) showing the joint portion.

[0026] The joint portion of the base material 21 is configured by positioning the joint portion of the base material 21 (for example, the base material 21B) overlapping the outer surface side (the side where the artificial hairs H are planted) where the artificial hairs H are planted, with respect to the joint portion of the base material 21 (for example, the base material 21A, see FIG. 3(c)) located on the inner surface side (scalp side). The joint portion of the base material 21A located on the inner surface side is configured so that no fold is provided so that only a step corresponding to the thickness of the base material 21 is generated on the inner surface side of the wig base 10. Therefore, the joint portion is configured so that only a step corresponding to the thickness of the base material 21 located on the inner surface side is generated on the inner surface side of the wig base 10. As a result, the step on the inner surface side of the joint portion is suppressed to only the thickness of the base material 21, so that the discomfort when the joint portion comes into contact with the wearer's head can be reduced. It is not necessary to configure the outer edge portion of the base material 21 overlapping the outer surface side so as not to provide a fold, and the joint portion may be reinforced by providing a fold.

[0027] In addition, outer edge 21D forming the outer peripheral portion of base material 21 located on the inner surface side is positioned on the inner surface side and more inward than the outer edge portion (portion close to outer edge 21E) of base material 21 overlapping the outer surface side, and the two base materials 21 are integrated by adhesion. Therefore, since there is no need to provide seams at the joint portions of base materials 21, it is possible to reduce discomfort when the joint portions come into contact with the wearer's head.

[0028] The bonding of the base material 21 can be achieved by, for example, hot melt bonding. In this case, the bonding may be set in a line, but it is preferable to use dot bonding, in which a large number of dot-like bonding portions 22 are set at intervals. This can prevent the contraction property of the base material 21 from changing between the bonding portion and its vicinity, as compared to the case where dot bonding is not used. In addition, the wig base 10 can be made to easily fit the head without impairing the stretchability in the direction in which the bonding portions continue. Note that in Figs. 3(a) and (b), the dot-like bonding portions 22 are shown by thin lines, and in Fig. 3(c), the bonding portions 22 are shown diagrammatically.

[0029] It is more preferable that the bonding portions are arranged in two rows of dots, with the bonding portions 22. It is also preferable that the bonding portions 22 in one row are configured to include areas in which the bonding portions 22 in one row are offset from the bonding portions 22 in the adjacent row so that they are not adjacent to each other, thereby providing both elasticity and strength. The interval between the dots is preferably set within a range of about 3 mm to about 10 mm, and is preferably set to about 5 mm.

[0030] In this way, by providing no seams at the joints of the base material 21 and limiting the step on the inner side of the joints to only the thickness of the base material 21, it is possible to provide a wig base 10 suitable for a full-head type wig that covers most of the head. In particular, even when used by a patient undergoing treatment who has little natural hair and is susceptible to irritation to the skin, the wig W does not wrinkle or is not strongly rubbed by the step at the joints, and a wig base 10 suitable for medical wigs can be provided.

[0031] Next, other characteristic parts will be described with reference to Fig. 4. Fig. 4(a) is a side view of the wig base 10, (b) is a cross-sectional view taken along line BB showing the periphery of the deformation restricting part 24, and (c) is a cross-sectional view taken along line CC showing the outer peripheral edge part. Note that in Fig. 4(a), dot-like adhesive parts 26 are shown by thin lines, and in Fig. 4(b), adhesive parts are shown by dashed lines.

[0032] The wig base 10 is provided with a deformation restricting portion 24 that is configured by including a deformation restricting material 23. The deformation restricting material 23 can be configured by forming a shape memory alloy (for example, a Ni-Ti alloy), a copper alloy, or a stainless steel alloy into a strip shape, or can be configured by hard plastic.

[0033] The deformation restricting portion 24 is also preferably configured by forming a bag-like portion by adhesion so that the seam does not cause discomfort when the wig base 10 is worn, and it is preferable to use dot-like adhesive portions 26 of approximately the same size as the joint portion of the base material 21. The material of the cover material 25 attached to the outer surface side is also preferably the same as that of the base material 21. In addition, in order to prevent a large step from occurring on the inner surface side of the wig base 10, the cover material 25 is preferably provided on the outer surface side where the artificial hair H is planted. In this case, the cover material 25 forms a bag-like portion that bulges outward, and the cover material 25 is preferably bonded to the base material 21 with a length set to be convex on the outer surface side so that the protruding portion on the inner surface side of the wig base 10 is reduced. In addition, the deformation restricting portion 24 is illustrated as being provided on the sideburns, but it may be provided on other parts such as the hairline and nape.

[0034] Next, a description will be given of the shape adjustment function of the outer peripheral edge portion of the wig base 10. As shown in Fig. 4(c), the outer peripheral edge portion of the wig base 10 has a constant thickness and is configured in a shape without folds. Therefore, the shape of the outer edge of the wig base 10 can be freely changed by cutting it with scissors, and the external shape that becomes the outline can be adjusted.

[0035] When manufacturing the wig base 10 of the present invention, first, two or more base materials 21 are joined at the joints to produce a wig base 10 having a non-folded section in at least a portion of the outer peripheral edge portion of the wig base 10 (base manufacturing process).

[0036] Thereafter, at least a part of the outer peripheral edge portion of the wig base 10 manufactured in the base manufacturing process is cut and removed, thereby adjusting the size of the wig base 10 to fit the wearer (size adjustment process).

[0037] In this way, by carrying out the size adjustment process, it is not necessary to manufacture the wig base 10 in a dedicated shape for each wearer. Therefore, it is possible to easily produce a large number of wig bases 10 of the same shape, and the manufacturing cost of the wig W can be reduced. The part where the shape can be adjusted does not have to be the entire circumference of the outer edge part of the wig base 10, but it is possible to make the shape adjustable only in a part of the hairline, nape, around the ears, etc., and to configure it so that the part where the shape cannot be adjusted is included as part of the outer edge part by setting a part where a fold is provided.

[0038] The present invention is not limited to the above-described embodiment of the invention, and can of course be modified to another embodiment that provides the same effects as those described above.

[0039] For example, an anti-slip function may be added to the inner surface of the wig base 10, and a thin sheet-like anti-slip member (not shown) may be adhered to the inner surface of the base material 21. The anti-slip member may be made of a silicone sheet, and may have many convex portions on its surface. [Industrial Applicability]

[0040] The wig base of the present invention can be used for wigs with artificial hair implanted, and can be suitably used for full-head wigs that cover most of the head. It can also be used for medical wigs for patients undergoing treatment who have little natural hair and are susceptible to irritation to the skin. [Explanation of symbols]
