WIG AND PROCESS FOR PREPARING A WIG

Abstract

A wig including a wig base having a wearing portion to be worn on a head; and a hair portion having hairs affixed to the wig base; the hair portion being cut such that at least one part of a first hair portion that is located on the head when the wig is worn on the head is configured to project toward the head.

Description

TECHNICAL FIELD

The present invention relates to a wig and a method for producing the wig.

BACKGROUND ART

Wigs have been used for visually concealing a decrease in a wearer's head hairs (making up a deficiency in a wearer's hair volume) or being utilized as a fashion accessory.

Such wigs have been desired to be naturally fitted to a wearer's hairs (wearer's own hairs) so as not to exhibit an artificial appearance in wearing. In the light of such desire, a wig has been proposed which includes artificial downy hairs at a portion thereof corresponding to a portion of a wearer's head where short and downy hairs grow in comparison to the remaining parts of the wearer's head, such as the hairline of a wearer's forehead, a wearer's head portions around his or her ears, and a wearer's hairline along his or her neck (see e.g. Patent Document 1).

DESCRIPTION OF EMBODIMENTS

First Embodiment

Now, embodiments of the present invention will be described in reference to the accompanying drawings. FIGS. 1(a) and (b) are schematic views of the wig according to a first embodiment. FIGS. 2(a) to (h) are schematic views illustrating modifications of the shape of a wig base 10. FIG. 3 is a schematic view illustrating portions of the wig according to the first embodiment.

FIG. 1(a) is a schematic view of the wig 1 seen from its rear side (side of the wig worn on a user's head hairs). FIG. 1(b) is a schematic view of the wig seen from its front side.

As illustrated in FIG. 1(a), the wig 1 includes the wig base 10, false hairs 20 (hair portion), and a securing member 30 (wearing portion).

Although the illustrated wig 1 is of a type which partially covers a user's head, the present invention is also applicable to a type which wholly covers a user's head. The wig 1 is applicable to both of a woman and a man.

The following explanation will be made such that a user's head is called a “head He”, and his or her own hairs are called “his or her own hairs Hai”. With regard to the front and rear sides of the wig 1, a side of the wig 1 that is seen by another person when the wig is worn on the head He is called a “front side” while the side of the wig 1 that is opposite to the front side and is closer to the head He than the front side is called a “rear side”. The wording “temperature” described later is expressed in degrees centigrade. The wording “angular portion” described later means a sharp portion where two linear edges meet together. Further, the wording “heart shape” means a shape with the entire outline inscribed inside an inverted triangle as in a heart shape mark in playing cards, which has a valley portion deeply recessed inward in the vicinity of an upper central position, and a sharply projecting portion formed at a lower position opposite to the valley portion (for example, see the portion denoted by reference 10b in FIG. 2(c)) such that the shape is rounded as a whole.

The wording “valley portion deeply recessed inward” means an area recessed inward so as to be rolled from both sides such that a leading edge as the valley bottom is made sharp (for example, see the portion denoted by reference 10a in FIG. 2(c)). The wording “rounded as a whole” means having almost no linear area at the outer periphery and being delimited by a convex or concave curved portion.

The wig base 10 holds the false hairs 20 and the securing member 30. Preferably, the wig base 20 is light-weight and is excellent in air permeability. In the illustrated embodiment, the wig base is supposed to be made in the shape of a mesh (or a net).

There is no limitation to the material of the wig base 10. The wig base may be made of silk or nylon (polyamide fiber) for example.

Preferably, the wig base 10 is wholly formed in a gently curved shape with a bulge in the vicinity of a middle portion thereof so as to be fitted to the head He of a user. When the wig 1 is formed in a small size, the wig base may be formed in a planar shape without trouble.

Although the wig base 10 has a surface 11 exposed when seen from the rear side of the wig 1, the wig base is concealed by the false hairs 20 when seen from the front side of the wig 1 as illustrated in FIG. 1(b).

The wig base 10 has an area with the false hairs 20 affixed thereto, which has an outer peripheral outline that is wholly rounded without an angular portion (in other words, is at least partially formed in an arcuate shape). In FIG. 1(a), the wig base is shown to be formed in a substantially oval shape when viewed in a plan view (hereinbelow, explanation about the shape of the outer peripheral outline will be made on the assumption that the shape is viewed in a plan view). On the surface 11 of the wig base 10, the securing member 30 is disposed at a certain position or certain positions. In FIG. 1(a), the securing member is shown to be disposed at one position in a substantially central position.

On the wig base 20, the false hairs 20 are affixed so as to extend and spread in a radial fashion.

As illustrated in FIGS. 2(a) to (h), the outer peripheral outline of the wig base 10 and the disposition arrangement of the securing member 30 are variable. The wig base 10 and the securing member 30 are schematically illustrated in FIGS. 2(a) to (h), and the size ratio between both members is not limited to the ones illustrated in FIGS. 2(a) to (h).

In FIG. 2(a), the wig base 10 is shown to be formed in a substantially oval shape as the outer peripheral outline. The wig base 10 has totally two securing members 30 disposed at respective opposite end portions so as to be spaced apart from each other. The two securing members 30 are disposed on an imaginary straight line (see the dotted line in this figure) extending in a longitudinal direction of the wig base 10.

The securing members 30 may be disposed, being turned at a certain angle in a planar direction. The planar direction means lateral and vertical directions when FIGS. 2(a) to (h) are viewed from the front.

For example, assuming that FIG. 2(a) illustrates a modification with 0 degree, the securing members may be disposed, being turned in a range from 0 degree to 180 degrees or 0 degree to −180 degrees. For example, the two securing members 30 may be disposed at different angles from each other in FIG. 2(a) (such that both securing members are disposed so as to be slant at 90 degrees from each other or to have a spacing therebetween gradually increasing in a downward direction when viewed in a planar view, for example). In a case where both members are disposed at different angles from each other, even when a force, which is enough to take off the wig base 10 (wig 1) worn on the head He, is applied to one of the securing members 30 for example, the other securing member 30 disposed at a different disposition angle serves as resistance to reduce the possibility that the wig base 10 (wig 1) would be taken off from the head He.

In FIG. 2(b), the wig base 10 is shown to be formed in a triangular shape as the outer peripheral outline so as to be a little bulged as whole as in a cam, such as a flat cam, when viewed in a plan view. The wig base 10 has totally four securing members 30 disposed at respective end portions so as to be spaced apart from one another. The four securing members 30 are disposed at the respective vertex portions of an imaginary quadrangle (see the dotted lines in this figure). The shape of a flat cam is also expressed as an oval shape, a rice ball shape or a teardrop shape. The shape modifications of the outer peripheral outline of the wig base 10 include such an oval shape, a rice ball shape and a teardrop shape.

In FIG. 2(c), the wig base 10 is shown to be formed in a substantially heart shape as the outer peripheral outline so as to have a sharp leading edge 10b formed at an edge portion opposite to an edge portion with the valley portion 10a formed therein such that the sharp leading edge projects outward. The wig base 10 has totally three securing members 30 disposed at respective end portions so as to be spaced apart from one another. The three securing members 30 are disposed at the respective vertex portions of an imaginary triangle (see the dotted lines in this figure).

As already described, the false hairs 20 are affixed so as to extend and spread in a radial fashion from the wig base 10. Accordingly, in the case of the wig base 10 with the valley portion 10a illustrated in FIG. 2(c), portions of the false hairs 20 adjacent to the valley portion 10a extend so as to intersect one another (see the arrows in this figure). In this way, the density of the false hairs increases an area adjacent to the valley portion 10a to enhance the feeling of volume in the wig.

The provision of the leading portion 10b contributes to give natural hair flow (natural stream) to the false hairs around the leading portion 10b in both left and right directions. For example, when the wig 1 is worn on a position adjacent to a whorl of hair on the back a user's head, the wig can naturally cope with the whorl of hair in either one of a clockwise direction and a counterclockwise direction.

FIGS. 2(d) and 2(e) illustrate variations of the modification illustrated in FIG. 2(c), wherein the aspect ratio of the heart shape, the depth of the valley portion and the degree of sharpness in the projecting leading portion are varied. As illustrated in these figures, many variations can be made to the aspect ratio of the heart shape, the depth of the valley portion, the degree of sharpness in the projecting leading portion and so on. When the wig bases 10 illustrated in FIGS. 2(d) and 2(e) are used, these wigs can achieve a similar advantage to the wig base 10 illustrated in FIG. 2(c).

The wig base 10 illustrated in FIG. 2(e) is formed in a smooth shape without having a leading edge portion similar to the leading edge portions 10b illustrated in FIGS. 2(c) and 2(d), and has five securing members 30 disposed thereon. Four securing members 30 among the five securing members are disposed at the vertex portions of an imaginary quadrangle (see the dotted lines in this figure where the imaginary quadrangle is trapezoidal), and the remaining one securing member 30 is disposed within an imaginary quadrangular area. When the remaining one securing member is disposed at the center of gravity of the imaginary quadrangle in this case, the wig base has a well-balanced appearance.

The wig base 10 illustrated in FIG. 2(e) is formed in a planar shape comparatively approximate to a round shape. The wig base formed in such a shape is suited to a wig covering a comparatively wide range of a user's head. The wig base illustrated in this figure is formed in a comparatively simple shape, achieving a reduction in production costs.

In FIG. 2(f), the wig base 10 is formed in a substantially gourd shape as the outer peripheral outline. The wig base 10 has totally two valley portions 10a formed on left and right edges thereof. The valley portions 10a may be disposed so as to be laterally symmetrical to each other or to be vertically apart and be offset from each other. The valley portions 10a may be disposed on upper and lower edges, not the left and right edges. The wig base 10 may have totally four valley portions 10a formed on upper, lower, left and right edges thereof. In FIG. 2(f), the wig base 10 is shown to have totally two securing members 30 disposed at respective opposite end portions so as to be spaced apart from each other as in the modification illustrated in FIG. 2(a).

When the wig base 10 illustrated in FIG. 2(f) is used, the density of the false hairs increases in areas adjacent to the two valley portions 10a to enhance the feeling of volume in the wig. Even when parting is made in the false hairs, the false hairs are difficult to be parted, mingling with a user's own hairs Hai in a natural fashion.

FIGS. 2(g) and 2(h) illustrate further variations of the wig base 10, wherein the wig bases have such an outer peripheral outline that plural wig bases 10 in a substantially oval shape as in the wig base illustrated in FIG. 2(a) are prepared, are placed one after another, being shifted by a certain angle of turn, and are merged at outer peripheral edges.

Specifically, the wig base 10 illustrated in FIG. 2(g) is wholly formed in such a substantially throwing knife shape that two wig bases 10 formed as in the wig base illustrated in FIG. 2(a) are prepared, one of them is placed on the other, being turned at an angle of about 90 degrees, and are merged at outer peripheral edges. The wig base 10 illustrated in FIG. 2(g) has totally four securing members 30 disposed at respective end portions so as to be spaced apart from one another. The four securing members 30 are disposed at the respective vertex portions of an imaginary quadrangle (not shown) as in the wig base illustrated in FIG. 2(b).

The wig base 10 illustrated in FIG. 2(g) is allowed not only to increase the number of the valley portions 10a but also to dispose the valley portions with good balance in comparison with the wig bases 10 illustrated in FIG. 2(c) and so on. In this way, the variation illustrated in this figure is allowed not only to increase the number of the locations capable of achieving the advantage by the valley portions 10a but also to neatly organize the valley portions in appearance.

The wig base 10 illustrated in FIG. 2(h) is formed in such a shape that four wig bases 10 formed as in the wig base illustrate in FIG. 2(a) are prepared, the four wig bases are placed one after another, being shifted by an angle of about 45° and are merged at a peripheral edges. The wig base 10 illustrated in FIG. 2(g) has totally four securing members 30 disposed at end portions, respectively. The four securing members 30 are disposed at the respective vertex portions of an imaginary quadrangle (not shown) as in the wig base illustrated in FIG. 2(b).

The use of the wig base 10 illustrated in FIG. 2(h) achieves a similar advantage to the wig base 10 illustrated in FIG. 2(g).

This is an explanation of the wig base 10. The outer peripheral outline of the wig base 10 and the disposition arrangement of the securing member(s) 30 are variable. For example, each of the outer peripheral outline shapes and each of the disposition arrangements of the securing member(s) 30 illustrated in FIGS. 2(a) to (h) may be combined. The outer peripheral outline in each of the modifications illustrated in FIG. 2(a) to (h) may be partially mixing.

For example, the modification illustrated in FIG. 2(a) may have the outer peripheral outline partially missing so as to be formed in a substantially crescent shape, or the modification illustrated in FIG. 2(c) may be halved to be formed in a half heart shape. For example, the wig base may be formed in a shape suggestive of a maple-like leaf or a shape of the spade or clover marks playing cards. When the outer peripheral outline of the wig base 10 is formed as explained above, it is also possible to enhance designability.

The false hairs 20 may be, for example, human hairs, artificial hairs or mixed hairs with human hairs and false hairs combined together and be affixed to the wig base 10 by a known affixing method. The false hairs 20 may be animal hairs in some cases.

The artificial hairs may be made of an acrylic material, chemical fibers, a nylon material or the like, the use of which has an advantage of easily reducing the weight of the wig 1. The human hairs have an advantage of giving a more natural appearance or feeling of touch to a viewer. The mixed hairs have both advantages achieved by artificial hairs and human hairs. The animal hairs have an advantage of easily reducing the production costs of the wig 1.

As illustrated in FIG. 3, at least some portions of the false hairs 20 (first hair portion) on the rear side of the wig 1 are formed so as to pop out (fuzz up) toward the head He (hereinbelow, also referred to such pop-out portions as fuzzy portions F). Reference symbol “Sc” in FIG. 3 means the scalp of a user (also applicable to FIG. 5).

Each of the fuzzy portions F may include a single independent false hair 20 or plural false hairs gathering together.

The fuzzy portions F may be formed by tapering false hairs 20. Tapering is a technique for shaving hairs by use of a cutter, such as a shaving razor (hereinbelow, also referred to razor). For example, hairs are cut so as to gradually increase the shaving amount of false hairs 20 on the rear side from their roots toward their tips. Tapering is also called taper cut in some cases.

Now, a specific example of the formation of the fuzzy portions F by tapering will be described.

(1) A hair panel (plate-like buddle of hairs taken out for tapering) is prepared while false hairs 20 are combed.

(2) A razor blade is brought into close contact with a surface of the hair panel (surface with a fuzzy portion F of the false hairs 20 formed thereon) while a certain tension is applied to the heir panel from the root toward the tip of the hair panel.

(3) The false hairs 20 are cut at a certain length while the razor blade is being moved toward the tips, being brought into close contact with the false hairs 20. While the razor blade is being moved, it is preferred that the angle included between the razor blade and the false hairs 20 (inclination angle at which the razor blade raises from the false hairs 20) be kept constant. The angle is preferably at least 10 degrees and at most 35 degrees, more preferably at least 20 degrees and at most 32 degrees, furthermore preferably at least 28.5 degrees and at most 29.5 degrees.

(4) Thus, the cut false hairs 20 pop out.

(5) Steps (1) to (4) are repeated until the fuzzy portions F are formed in a certain mount.

Tapering may be applied to false hairs 20 affixed on the wig base 10 or be applied to false hairs 20 before the false hairs are affixed. In the latter case, the false hairs 20 are affixed to the wig base 10 after tapering. The securing members 30 may be disposed on the wig base 10 after tapering or before tapering. In other words, there is no particular limitation to the order of the step for tapering false hairs 20, the step for affixing the false hairs 20 to the wig base 10 and the step for disposing the securing members 30 on the wig base 10.

The technique used for forming the fuzzy portions F is not limited to tapering. Various kinds of techniques, such as setting-cut or pointing-cut, may be applied. These techniques may be used in combination. Scissors may be used instead of a razor.

The securing member or securing members 30 will be described in detail in reference to FIGS. 4(a) to (d). FIGS. 4(a) to (d) illustrate schematic views of a securing member 30 of the wig according to the first embodiment. FIG. 4(a) illustrates a front view of the securing member 30. FIG. 4(b) illustrates an enlarged cross-sectional view taken along line A-A in FIG. 4(a), wherein the securing member 30 is shown to be in a state of being curved in a concave shape (state of being worn on a user's hairs). FIG. 4(c) is an enlarged cross-sectional view taken along line A-A in FIG. 4(a), wherein the securing member 30 is shown to be in a state of being curved in a convex shape (state of being out of engagement with the user's hairs). FIG. 4(d) illustrates an enlarged view of a leading edge portion of a comb-like member 33.

As illustrated in FIG. 4(a), the securing member 30 includes a curved plate member 31, an elastic member 32 and the comb-like member 33.

The curved plate member 31 is attached to the wig base 10, resulting in the securing member 30 being mounted to the wig base 10. There is no particular limitation to the method for attaching the curved plate member 31 to the wig base 10. The curved plate member 31 may be attached to the wig base 10 by a desired method, such as sawing, fixing by use of an adhesive or fixing by use of an eyelet.

The curved plate member 31 is a flexible flat plate transformable between the concave shape and the convex shape and is configured to have a space 310 formed in a middle portion so as to be surround by a peripheral edge portion 311.

The elastic member 32 is disposed on the peripheral edge portion 311 of the curved plate member 31 as illustrated in FIG. 4(a) and so on. In this embodiment, the elastic member 32 is disposed on a side of the peripheral edge portion 311 where the leading edge portion of the comb-like member 33 is located. The elastic member 32 is disposed to be brought into pressure contact with the comb-like member 33 in order to increase the clamping force between both members during pressure contact when the comb-like member 33 is pressed against the curved plate member 31 as illustrated in FIG. 4(b).

The provision of the elastic member 32 is helpful to reduce the possibility that the wig 1 could damage a user's own hairs Hai at the time of wearing. There is no particular limitation to the material of the elastic member 32. The elastic member may be made of millable silicone rubber for example.

The comb-like member 33 includes a plurality of flexible bars 330 having a small diameter. For easy understanding of the figure, only some of the bars 330 among all bars are denoted by reference numeral “330”. The bars 330 are disposed in a width direction orthogonal to a longitudinal direction of the curved plate member 31 so as to be side by side and apart from each other at the certain intervals. Each of the bars 330 has a base end portion supported in a cantilever manner, fixed to one side 311a of both sides opposed across the space 310 in the peripheral edge portion 311. Each of the bars 330 has a leading edge formed in a spherical shape. Since the leading edge is formed in a spherical shape, it is possible to reduce the possibility that a scalp with the wig 1 thereon would be scratched, for example, when the wig 1 is worn on the head He, or the wig is taken off from the head He.

When the curved plate member 31 is curved in a concave shape as illustrated in shown in FIG. 4(b), the comb-like member 33 is pressed against to the curved plate member 31 to bring partial surfaces of the leading edge portions of the bars 330 into close contact with the elastic member 32.

In contrast, when the curved plate member 31 is inverted into a convex shape as illustrated in FIG. 4(c), the comb-like member 33 is out of pressure engagement with the curved plate member 31 with the result that the bars 330 move in a direction away from the curved plate member 31, being pivoted about the base end portions of the bars. In this case, a gap 34 is formed between the comb-like member 33 and the curved plate member 31.

Although each of the bars 330 may extend straight from its base end portion, each of the bars is bent at its middle portion in this embodiment. Each of the bars is bent as described to improve the clamping force in the state illustrated in FIG. 4(b) and reduce a local pressure to a user's head He as much as possible.

Each of the bars 330 has such a layered structure that the leading portion including the leading edge formed in the spherical shape is partly coated with a coating material 331 as illustrated in FIG. 4(d). Although not shown, each of the bars 330 has a synthetic resin layer (such as a silicone resin layer) interposed between each of the bars 330 and the coating material 331 to fix the coating material 331 to each of the bars 330.

There is no limitation to where coating should be made with the coating material 331. For example, each of the bars 330 may have only the spherical portion of its leading edge portion coated, may be coated at its portion between the spherical portion of its leading edge and an end edge portion of the elastic member 32 (portion located in the space 310 and facing 311a in FIG. 4(a)), or may have wholly coated. Further, the curved plate member 31 may be coated together with the bars.

The coating material 331 contains at least silk powder and/or far-infrared ray ore powder.

As specific examples of the coating material 331, explanation will be made about a case where the coating material 331 contains silk powder (in other words, the coating material 331 is almost wholly made of silk powder), a case where the coating material contains far-infrared ray ore powder (in other words, the coating material 331 is almost wholly made of far-infrared ray ore powder), and a case where the coating material is made of silk powder and far-infrared ray ore powder.

(Case Where Silk Powder is Used)

When silk powder is used as the coating material 331, a silicone resin is applied to the comb-like member 33 by a certain length from the leading spherical portions (such as a length from the leading spherical portions to portions facing the end edge portion of the elastic member 32), followed by coating the resin-applied surface with the silk powder.

The silk powder has a particle size of preferably at least 50 mesh pass, more preferably 100 mesh pass. The term “mesh pass” means a mesh size (the size of openings of a sieve for screening granular substances (ASTM standards)). For example, 50 mesh pass means that the particles of silk powder pass through a sieve with 50 mesh. As the value of the mesh size increases, the size of the openings of a sieve decreases. The mesh size is convertible to the size of the openings of a sieve according to the JIS standards. For example, 50 mesh size is equivalent to 300 μm.

As the particle size of silk powder decreases, the coating material 331 of the silk powder becomes smoother to appropriately reduce the possibility that a user's own hairs Hai could be damaged by being brought into contact with the bars.

(Case Where Far-Infrared Ray Ore Powder is Used)

Far-infrared ore powder is ore powder, which is excellent in far-infrared ray radiation at a room temperature (RT) to about at 40° C.

When far-infrared ray ore powder is used as the coating material 331, a silicone resin is applied to the comb-like member 33 by a length from the leading spherical portion to a certain portion (such as a length from the leading spherical portions to portions facing the end edge portion of the elastic member 32), followed by coating the resin-applied-surface with the far-infrared ray ore powder and coating the far-infrared ray ore powder applied-surface with the silicone resin.

The far-infrared ray ore powder preferably has infrared radiation energy (in integral value) in a wavelength region of 2 to 25 (μm), which is at least 320(W/m²) and at most 462 (W/m²) (equal to the infrared ray radiation energy of an ideal black body (full radiator) in the same wavelength region). The infrared ray radiation energy more preferably has a lower limit of at least 422 (W/m²).

As the level of the infrared ray radiation energy increases (approaches to that of the infrared ray radiation energy of a black body), it is possible to appropriately enhance the blood flow in the scalp of the head He. From this point of view, the far-infrared ray radiation ore powder has a radiation rate (ratio of the infrared ray radiation energy to a black body, represented by % here) of at least about 70%, more preferably a value closer to 100%.

The far-infrared ray ore powder has a particle size of preferably at least 50 [Me-pass], more preferably 100 [Me-pass]. As the particle size of the far-infrared ray ore powder decreases, the coating material 331 made of the far-infrared ray ore powder becomes smoother to make it easier to have a beautiful appearance.

The far-infrared ray ore powder can emit far-infrared rays to increase the blood flow in the scalp of the head He. Thus, it is possible to prevent hair loss and to promote hair growth. As described above, the far-infrared ray ore powder can be coated with the silicone resin to appropriately reduce the possibility that a user's own hairs Hai could be damaged by being brought into contact with the far-infrared ray ore powder.

(Case Where Silk Powder and Far-Infrared Ray Ore Powder are Used)

When silk powder and far-infrared ray ore powder are used as the coating material 331, a silicone resin is applied to the comb-like member 33 by a length from the spherical portion to a certain portion (such as a length from the leading spherical portions to portions facing the end edge portion of the elastic member 32), followed by coating the resin-applied surface with the far-infrared ray ore powder, applying the silicone resin to the powder-applied surface and coating the resin-applied surface with the silk powder. Thus, it is possible to have both of the advantage offered by the use of the silk powder and the advantage offered by the use of far-infrared ray ore powder, which are described above.

(Method of Use)

Now, explanation will be made about how to use the first embodiment in reference to FIG. 5. FIG. 5 is a schematic view illustrating how to use the wig according to the first embodiment. In FIG. 5, only a portion of the wig 1 is illustrated for simple visual comprehension. In the following explanation, FIGS. 4(a) to (d) and so on are also referred to as needed.

First, a user sets the securing member 30 so as to have the curved plate member 31 inverted and curved into a convex shape to open the comb-like member 33 as illustrated in FIG. 4(c), puts the wig 1 on a portion of his or her head He to wear and close the securing member 30 as illustrated in FIG. 4(b). Thus, the wig 1 is worn on the head He.

The user causes his or her own hairs Hai and the false hairs 20 to mingle by use of a hand or comb, placing both types of hairs in a state without a sense of incompatibility in appearance. In this state, the fuzzy portions F come into between his or her own hairs Hai, overlap his or her own hair or get entangled with his or her own hair.

As described above, the wig 1 according to this embodiment of the present invention is characterized to include a wig base (wig base 10) having a wearing portion (securing member 30) to be worn on a head He, and a hair portion (false hairs 20) having hairs (false hairs) affixed to the wig base, wherein the hair portion is cut such that at least one part of a first hair portion that is located on the head (rear side of the wig base) when the wig is worn on the head (ones of the false hairs 20 that are located on the rear side) is configured to project toward the head.

At least one part of the first hair portion (ones of the false hairs 20 located on the rear side) is cut so as to be configured to project toward the head. The false hairs 20 thus cut on the rear side (fuzzy portions F) come into his or her own hairs Hai, overlap with his or her own hairs Hai or get entangled with his or her own hairs Hai with the result that the false hairs 20 and his or her own hairs Hai become difficult to separate from each other to reduce the possibility that false hairs 20 would lift from his or her own hairs Hai. Thus, it is possible to effectively reduce that wearing of the wig would appear to be unnatural.

The wig base 10 according to the present invention is characterized to have an area with false hairs affixed thereto, which has an outer peripheral outline that is at least partially formed in an acute shape. The outer peripheral outline in an acute shape is compatible with the curved surface of a user's head He to reduce the possibility that the wig base 10 would unnaturally lift from his or her own hairs.

The wearing portion (securing member 30) is characterized to clamp hairs to wear the wearing portion thereon (user's own hairs Hai) and has a protection layer (coating material 331) formed at least partly thereon to protect the hairs to wear the wearing portion thereon (user's own hairs Hai). The provision of the coating material 331 can reduce the possibility that the user's hairs or scalp would be damaged when using the wig 1.

The wig base 10 may have the wearing portion (securing member 30) disposed at two or more positions. When the wearing portion (securing member 30) is disposed at two or more portions, the wig 1 can be reliably worn.

The present invention is also characterized to provide a method including a step for preparing a wearing portion to be worn on a head He (securing member 30), a step for preparing a wig base (wig base 10), the wig base being to have the wearing portion attached thereto, a step for attaching the wearing portion to the wig base, a step for preparing hairs (false hairs 20), a step for affixing the hairs to the wig base, and a step for cutting the hairs such that at least one portion of hairs that are located on the head when the wig is worn on the head is configured to project toward the head.

(With Regard to Variations)

As described above, the explanation has been made about the first embodiment of the present invention. Various variations are applicable to the present invention. Now, some variations of the present invention will be described.

(Variation 1)

FIG. 6 is a schematic view of the wig according to variation 1 of the present invention. The present invention encompasses a type of wig 2 having a narrow width as illustrated in FIG. 6.

The wig 2 is of a type which has a limited covering portion of the head He of a user in comparison with the wig 1 according to the first embodiment of the present invention. This wig can provide hairs with a fashionable impression at a one point.

Although the wig 2 has a wig base 10 exposed on the premise that the wig base 10 is concealed by a user's own hairs Hai, the wig may be configured so as to have the wig base 10 concealed by false hairs 20 as illustrated in FIG. 1(b). The wig 2 is worn on the head He by a securing member 30 as in the wig 1.

(Variation 2)

FIG. 7(a) to (d) are schematic views illustrating the wig according to variation 2 of the present invention. FIGS. 7(a) to (d) schematically depict false hairs 20 in outline for simple visual comprehension. It should be noted that variation 2 of the present invention illustrated in FIGS. 7(a) to (d) is applicable to both of wig 1 illustrated in FIGS. 1(a) and (b) and so on, and wig 2 illustrated in FIG. 6.

As illustrated in FIGS. 7(a) to (d), the wig may have a fuzzy portion F locally disposed thereon. For example, the fuzzy portion F may be disposed at a position close to the roots of the false hairs 20 as illustrated in FIG. 7(a), or the fuzzy portion F may be disposed at a position close to the roots of the false hairs and a position close to the tips of the false hairs as illustrated in FIG. 7(b).

The fuzzy portion F may be disposed at an intermediate position between the roots and the tips of the false hairs 20 as illustrated in FIG. 7(c) or at a position close to the tips of the false hairs as illustrated in FIG. 7(d). The false hairs are firmly affixed to the head He at their roots by a securing member 30 (not shown). In light of this reason, in a case where the fuzzy portion F is locally deposed, when the fuzzy portion is disposed at a position apart from the securing member 30, in other words, a position closer to the tips than the roots, it is possible to appropriately reduce the possibility that the wig would lift from a user's own hairs or shift from the wearing position to cause wig-wearing to appear to be unnatural.

(Variation 3)

FIGS. 8(a) to (c) are schematic views illustrating the wig according to variation 3 of the present invention. FIGS. 8(a) to (c) schematically depict false hairs 20 in outline for simple visual comprehension as in FIGS. 7(a) to (d). Variation 3 of the present invention illustrated in FIGS. 8(a) to (c) is applicable to both the wig 1 illustrated in FIGS. 1(a) and (b) and so on, and the wig 2 illustrated in FIG. 6.

As illustrated in FIGS. 8(a) to (c), the wig may have a fuzzy portion F projecting by locally varying lengths. For example, the fuzzy portion may be formed so as to have longer lengths gradually from the tips toward the roots of the false hairs 20 as illustrated in FIG. 8(a), to have longer lengths gradually from the tips toward the roots, followed by having extremely short lengths and having longer lengths toward the tips as illustrated in FIG. 8(b), or to have shorter lengths gradually from the tips toward the roots, followed by becoming gradually longer as illustrated in FIG. 8(c). The formation position or positions of the fuzzy portion F illustrated in FIGS. 8(a) to (c) are examples, and the present invention is not particularly limited to the illustrated modes. The present invention encompasses a pattern where the fuzzy portion F is wholly formed along the length direction of the false hairs 20 as illustrated in FIG. 3 or FIG. 6, and a pattern illustrated in each of FIGS. 7(a) to (d).

(Other Modifications)

The present invention is applicable not only to the above-mentioned wigs but also to hair extensions (hereinbelow, referred to as extensions) to be attached at a hair salon or the like. Extensions have been recently available which are sold by mail order or the like, instead of being not attached at a hair salon, and are easily bought and worn by a user. Detailed explanation about such extensions will be omitted because such extensions correspond to the wig 2 according to variation 1 illustrated in FIG. 6.

EXAMPLE 1

The inventors had each of two subjects (subject 1: 50 years old male, subject 2: 46 years old female) wear sample A and sample B as the securing member 30, and sample C as a securing member for comparison to conduct an inspection to see whether the provision of the coating material 331 would be helpful to reduce the damage to his hairs and scalp and her hairs and scalp. Further, a portion of his head with no securing member thereon and a portion of her head with no securing member thereon were used as samples D, and an inspection about such potions as samples D was also conducted. It should be noted that the present invention is not limited to the examples.

First, samples A to D will be described in detail.

(Sample A)

A silicone resin were applied to a comb-like member 33 by a length from the spherical leading portions to portions facing the end edge portion of the elastic member 32, followed by coating the resin-applied surface with silk powder (having a particle size of 100 Me-pass).

(Sample B)

A silicone resin was applied to a comb-like member 33 by a length from its spherical leading portions to portions facing the end edge portion of the elastic member 32, followed by coating the resin-applied surface with far-infrared ray ore powder (having a particle size of 100 Me-pass) and coating the ore powder-applied surface with a silicone resin. The far-infrared ray ore powder of sample B had infrared radiation energy (integral value) of 422 [W/m²] in a wavelength region of 2 to 25 [μm]. An ideal black body (full radiator) has infrared radiation energy of 462 [W/m²], and the far-infrared ray ore powder of sample B has radiation rate of 91 [%].

(Sample C)

This sample was a securing member, which had a surface coated with the silicone resin without the application of another coating made of, e.g. silk powder or far-infrared ray ore powder used in the above-mentioned sample A or sample B.

(Sample D)

These samples were portions of the subjects' heads with no securing member worn thereon.

<With Regard to Inspection>

FIG. 9 is a schematic view of a subject's head seen from the head top. The hair inspection and the scalp inspection were performed, having each of the subjects where sample A, sample B and sample C were worn on respective positions of his or her head as illustrated in FIG. 9. In other words, the wearing positions were a right front vertex for sample A, a left front vertex for sample B, a right occiput for sample C and a right occiput for sample D. The sample D was positioned on a left occiput.

The procedure steps in the hair inspection and the scalp inspection will be described in detail.

(Procedure Step 1)

It was confirmed that the two subjects had no problem with his or her scalp and hairs. The use of a hair tonic shampoo, a hair growing agent or the like was prohibited, having spicy food was limited, and the subjects were encouraged to take a sleep for a period of time suited to them in a period required for normalizing their scalp before inspection to conduct preparation with their physical conditions taken into consideration.

(Procedure Step 2)

On the date of inspection, the two subjects were standby, sitting on chairs for about 10 minutes in a room having a room temperature of 25° C. and a humidity of 50% to be acclimated (accustomed) to the environment in the inspection room.

(Procedure Step 3)

Hair and scalp inspections were performed on the planned wearing positions illustrated in FIG. 9 before the subjects wore sample A and so on after completion of acclimation. The hair inspection was performed, using an optical microscope in a replica method. Hereinbelow, the images to be explained were taken with the magnification of the optical microscope being set to 100 times.

A hair has a layered structure including a hair medulla, a hair cortex (cortex) and a hair cuticle (cuticle pili or outermost layer of a hair) from a center toward the outside. In the hair inspection, the state of the cuticle in the layered structure was inspected.

The “hair cuticle” is a portion covering the surface of a hair, which is helpful to protect the inside of the hair from an external stimulus and to prevent the protein and the moisture in the hair cortex from being lost. The hair cuticle is configured such that normally six to eight extremely thin cells were brought into close contact so as to overlap in a scale-like manner (scale-like pattern) and in layers from the root toward the tip.

The hair cuticle includes, as its component, keratin (rigid protein) having much sulfur content. Although the hair cuticle is rigid, the hair cuticle is likely to be damaged or peeled by application of an excessive force, such as brushing, because of being brittle and being susceptible to friction. A heathy hair has a scale-like pattern formed so as to be regularly arrayed in a wavy shape while a damaged hair has a scale-like pattern disturbed.

The scalp inspection was performed by use of a microscope (magnification display device including a high pixel color camera, lighting, lenses having different magnifying powers, connection cables and so on) and a thermography camera. The images to be explained hereinbelow were taken with the magnification of a microscope being set to 50 times. As the thermography camera, a product was used, which was available under the product name of TVS-700 manufactured by Nippon Avionics Co., Ltd.

(Procedure Step 4)

The two subjects passed the time, wearing sample A, sample B and sample C, in a room prepared for them. At that time, they were allowed to freely move around in the room while they were prohibited from going out or doing a heavy physical activity, such as sweating.

(Procedure Step 5)

After the lapse of about 5 hours and the lapse of about 10 hours since sample A, sample B and sample C were worn, the same step as procedure step 2 was taken to perform acclimation, and the same step as procedure step 3 was taken to perform the hair and scalp inspections.

Results of the hair and scalp inspections are shown in FIG. 10(a) to FIG. 21(b).

First, the results of the hair inspection by use of an electronic microscope will be described in reference to FIG. 10(a) to FIG. 13(b).

FIGS. 10(a) and (b) and FIGS. 11(a) and (b) illustrate the results of the hair inspection for subject 1 (50 years old male). FIG. 10(a) illustrates a portion of his head with sample A worn thereon, FIG. 10(b) illustrates a portion of his head with sample B worn thereon, FIG. 11(a) illustrates a portion of his head with sample C worn thereon, and illustrated in FIG. 11(b) illustrates a portion of his head as sample D (with no securing member worn thereon).

Likewise, FIGS. 12(a) and (b) and FIGS. 13(a) and (b) illustrate the results of hair inspection for subject 2 (46 years old female). FIG. 12(a) illustrates a portion of a head with sample A worn thereon, FIG. 12(b) illustrates a portion of a head with sample B worn thereon, FIG. 13(a) illustrates a portion of a head with sample C worn thereon, and FIG. 13(b) illustrates a portion of a head as sample D (with no securing member worn thereon).

Subject 1 had his hairs placed in a good condition without disturbance in his scale-like pattern before wearing sample A. His hairs maintained a good condition even after the lapse of 5 hours since wearing, and the presence of disturbance in his scale-like pattern was not substantially confirmed even after the lapse of 10 hours since wearing (see FIG. 10(a)).

Subject 1 had his hairs place in a good condition without disturbance in his hairs before wearing sample B. His hairs maintained a good conditions even after the lapse of 5 hours since wearing, and the presence of disturbance in his scale-like pattern was not substantially confirm even after the lapse of 10 hours since wearing (see FIG. 10(b)).

Although subject 1 had his hairs placed in a good condition without disturbance in a scale-like pattern before wearing sample C, the presence of disturbance in a scale-like pattern (black and hole-like open portions in a hair shown in FIG. 11(a)) became noticeable after the lapse of 5 hours since wearing, and the disturbance in the scale-like pattern became finer after the lapse of 10 hours since wearing (see this FIG. 11(a)).

The inspection before wearing the respective samples revealed that subject 1 had his hairs as sample D placed in a good condition without disturbance in the scale-like pattern. The hairs maintained a good conditions even after 5 hours since wearing. After the lapse of 10 hours since wearing, the scale-like pattern became easily to be visually recognizable in a few portions, though definite disturbance was caused in the scale-like pattern (see FIG. 11(b)).

When sample A, sample B and sample C worn by subject 1 are compared to sample D based on the inspection results described above, it is revealed that almost no significant difference is recognized between sample A and sample D in terms of disturbance in the scale-like pattern, and that wearing sample A would not lead to damage in the hair cuticle.

It is revealed that almost no significant difference is recognized between sample B and sample D in terms of disturbance in the scale-like pattern, and that wearing sample B would not lead to damage in the hair cuticle.

It is revealed that a significant difference is recognized between sample C and sample D in terms of disturbance in the scale-like pattern, and that wearing sample C would not lead to damage in the hair cuticle.

Before wearing sample A, subject 2 had her hairs below this sample wholly placed in a good condition, though a black noticeable disturbance in the scale-like pattern was recognizable at an extremely small number of positions. After the lapse of 5 hours since wearing, it is confirmed that the scale-like pattern became easy to be visually recognizable in a few positions, though no definite disturbance was caused, and that her hairs had maintained the same condition even after the lapse of 10 hours since wearing (see FIG. 12(a)).

Before wearing sample B, subject 2 had her hairs below this sample placed in such a state that a scale-like pattern became easy to be visually recognizable in a few positions, though the hairs were wholly placed in a good condition. Her hairs had maintained the same condition even after the lapse of 5 hours and after the lapse of 10 hours since wearing (see FIG. 12(b)).

Before wearing sample C, subject 2 had her hairs subjected to no disturbance in a scale-like pattern and placed in a good condition. In contrast, disturbance in the scale-like pattern became noticeable in a black irregular manner in an image after the lapse of 5 hours since wearing, and the scale-like pattern was further disturbed after the lapse of 10 hours since wearing (see FIG. 13(a).

The inspection made before wearing these samples revealed that subject 2 had her hairs as sample D subjected to no disturbance in the scale-like pattern and placed in a good condition. Her hairs had maintained the same condition even after the lapse of 5 hours since wearing. After the lapse of 10 hours since wearing, the scale-like pattern became easily to be visually recognizable at a few positions (see FIG. 13(b)).

When sample A, sample B and sample C worn by subject 2 are compared to sample D based on the inspection results described above, it is revealed that the same results as those for subject 1 were obtained.

The results of the scalp inspection by use of a microscope will be described in reference to FIG. 14(a) to FIG. 17(b).

FIGS. 14(a) and (b) and FIGS. 15(a) and (b) illustrate the results of the scalp inspection of subject 1 (50 years old male) by use of the microscope. FIG. 14(a) illustrates a portion of his head with sample A worn thereon, FIG. 14(b) illustrates a portion of his head with sample B worn thereon, FIG. 15(a) illustrates a portion of his head with sample C worn thereon, and FIG. 15(b) illustrates a portion of his head as sample D (with no securing member worn thereon).

Likewise, FIGS. 16(a) and (b) and FIGS. 17(a) and (b) illustrate the results of the scalp inspection for subject 2 (46 years old female) by use of the microscope. FIG. 16(a) illustrates a portion of her head with sample A worn thereon, FIG. 16(b) illustrates a portion of her head with sample B worn thereon, FIG. 17(a) illustrates a portion of her head with sample C worn thereon, and FIG. 17(b) illustrates a portion of her head as sample D (with no securing member worn thereon).

The scalp of subject 1 was subjected to no change, such as a scratch or rough skin, from before wearing sample A to after the lapse of 10 hours since wearing (see FIG. 14(a)).

Likewise, the scalp of subject 1 was subjected to no change, such as a scratch or rough skin, from before wearing sample B to after the lapse of 10 hours since wearing (see FIG. 14(b)). The same was true for sample C and sample D (see FIG. 15(a) and FIG. 15(b)).

In other words, when sample A, sample B and sample C worn by subject 1 are compared to sample D based on the inspection results described above, it is revealed that no significant difference is recognized between any one of samples A, B and C and sample D, and that wearing sample A, sample B and sample C would cause no problem in his scalp.

The same is true for subject 2, and scalp was subjected to no change, such as a scratch or rough skin (see FIG. 16(a) to FIG. 17(b)). In other words, as in subject 1, when sample A, sample B and sample C worn by subject 2 are compared to sample D based on the inspection results described above, it is revealed that no significant difference is recognized between any one of samples A, B and C and sample D, and that wearing sample A, sample B and sample C would cause no problem in her scalp.

Now, the results of their scalp inspection by use of the thermography camera will be described in reference to FIG. 18(a) to FIG. 21(b).

FIGS. 18(a) and (b) and FIGS. 19(a) and (b) illustrate the results of the scalp inspection for subject 1 (50 years old male) by use of the thermography camera. FIG. 18(a) illustrates a portion of his scalp with sample A worn thereon, FIG. 18(b) illustrates a portion of his scalp with sample B worn thereon, FIG. 19(a) illustrates a portion of his scalp with sample C worn thereon, and FIG. 19(b) illustrates a portion of his scalp as sample D (with no securing member worn thereon).

Likewise, FIGS. 20(a) and (b) and FIGS. 21(a) and (b) illustrate the results of the scalp inspection for subject 2 (46 years old female) by use of the thermography camera. FIG. 20(a) illustrates a portion of her scalp with sample A worn thereon, FIG. 20(b) illustrates a portion of her scalp with sample B worn thereon, FIG. 21(a) illustrates a portion of her scalp with sample C worn thereon, and FIG. 21(b) illustrates a portion of her scalp as sample D (with no securing member worn thereon).

In FIG. 18(a) to FIG. 21(b), areas having a cool temperature are shown in black while areas having a warm temperature are shown in white.

It was confirmed that Subject 1 had not only areas having a cool temperature but also areas having a warm temperature on his scalp from before wearing sample A to after the lapse of 10 hours since wearing (see FIG. 18(a)).

It was confirmed that although subject 1 had not only areas having a cool temperature but also areas having a warm temperature on his scalp before wearing sample B, his scalp was largely occupied by areas having a warm temperature after the lapse of 5 hours since wearing, and this trend was true for his scalp after the lapse of 10 hours since wearing.

It was confirmed that Subject 1 had not only areas having a cool temperature but also areas having a warm temperature on his scalp from before wearing sample C to after the lapse of 10 hours since wearing. His scalp was, if anything, largely occupied by areas having a cool temperature after the lapse of 5 hours since wearing and after the lapse of 10 hours since wearing (see FIG. 19(a)).

It was confirmed that Subject 1 had not only areas having a cool temperature but also areas having a warm temperature on a portion of his scalp as sample D from before wearing the other samples to after the lapse of 10 hours since wearing the other samples as in sample A and sample C (see FIG. 19(b)).

When sample A, sample B and sample C worn by subject 1 are compared to sample D based on the inspection results described above, it is confirmed that although a difference in temperature is recognized between sample A and sample D, almost no significant difference is recognized between these samples in that his scalp had not only areas having a cool temperature but also areas having a warm temperature.

It was revealed that a significant difference was recognized between sample B and sample D, and that the areas having a warm temperature were continuously at warm temperatures on the portion of his scalp with sample B worn thereon.

It was confirmed that although a difference in temperature was recognized between sample C and sample D, almost no significant difference was recognized between these samples in that his scalp had not only areas having a cool temperature but also areas having a warm temperature.

In other words, when sample A, sample B and sample C worn by subject 1 are compared to sample D based on the inspection results described above, it is revealed that the areas having a warm temperature were continuously at warm temperatures on the portion of his scalp with sample B worn thereon. It is assumed that sample B enhanced the blood flow in the portion of his scalp with sample B worn thereon.

Subject 2 had not only areas having a cool temperature but also areas having warm temperature on her scalp from before wearing sample A to after the lapse of 10 hours since wearing the samples (see FIG. 20(a)).

It was confirmed that although subject 2 had not only areas having a cool temperature but also areas having a warm temperature on her scalp before wearing sample B, the areas having a warm temperature were increased after the lapse of 5 hours since wearing, and this trend became further significant after the lapse of 10 hours since wearing (see FIG. 20(b)).

Subject 2 had not only areas having a cool temperature but also areas having a warm temperature on her scalp from before wearing sample C to after the lapse of 10 hours since wearing. Her scalp was, if any, largely occupied by areas having a cool temperature after the lapse of 5 hours since wearing and after the lapse of 10 hours since wearing (see FIG. 21(a)).

It was confirmed that subject 2 had not only areas having a cool temperature but also areas having a warm temperature on the portion of her scalp as sample D from before wearing the other samples to after the lapse of 10 hours since wearing the other samples as in sample A and sample C (see FIG. 21(b)).

When sample A, sample B and sample C worn by subject 2 are compared to sample D based on the inspection results described above, it was confirmed that the same trend as subject 1 was applied, and that wearing sample B was allowed to maintain warm temperatures of the areas having a warm temperature on the portion of her scalp with sample B worn thereon. It is assumed that wearing sample B enhanced the blood flow in a scalp.

The following conclusion are suggested by the results described above:

(1) A securing member, which has a surface coated with a silicone material as in sample C without the application of another coating made of silk powder or far-infrared ray ore powder as in the above-mentioned sample A or sample B, could damage a hair cuticle as rigid keratin, depending on the hardness of the silicone material or the surface shape of the securing member.

(2) It is possible to appropriately control the damage of the cuticle by applying a securing member with a silk coating.

(3) It is considered that it is possible to appropriately control the damage of the cuticle and enhance the blood flow in a scalp by application of a coating made of far-infrared ray ore powder. The blood flow in a scalp can be enhanced to appropriately supply hairs with nutrition, with the result that it is expected to prevent hair loss and promote hair growth.
