Definitions

  • the present invention relates to an apparatus for wearing a wig that is bonded to the inside of a wig base, to which imitation hairs such as artificial hairs or human hairs are implanted, for easily and surely wearing a wig on a head of a wearer.
  • An inversion clip that is made of a metal or synthetic resin and fixed to the inside of a wig base, wherein the inversion clip is so bent as to hold the hairs of a wig wearer with teeth of the inversion clip (Patent Document 1); an apparatus on a back surface of a hair band having a structure, like a male sheet of a hook-and-loop fastener, in which a great number of monofilaments are disposed on a base sheet in the form of projection as an anti-slip tape (Patent Document 2); an apparatus having an head accessory put on a head such as a wig or a hat and a band-like member that elastically surrounds a head, wherein the band-like member and the head accessory put on the head can be attached to and detached from each other by means of attaching means such as a hook-and-loop
  • This device is used only to prevent a light head accessory put on a head, such as a hair band, from being slipped off from hairs with the structure of the monofilaments by being inserting into the hairs like teeth of a comb. Therefore, this device has weak fixing force to be used as an apparatus for wearing a wig, thus technically insufficient.
  • the band-lilce member is interposed between the head of the wearer and the wig base. Therefore, the wig is not fitted to the head of the wearer, but lifts up, and thus, other persons might notice that a wig is worn.
  • the hoolc-and-loop fastener is used as the attaching means, both of the male sheet and the female sheet are interposed between the head of the wig wearer and the wig base to increase the thickness, resulting in that it is difficult for the wig to be fitted to the head.
  • the band-like member is attached to the head of the wig wearer with its elastic force, like a hair band. Therefore, if the elastic force is weak, the wig is easily detached, while if the elastic force is increased, the head of the wig wearer is tightened, which makes it difficult to wear the wig for a long time.
  • the present invention is accomplished in view of the foregoing circumstances, and the object is to provide, with low cost, an apparatus for wearing a wig that can easily and surely attach a wig only by lightly pressing the wig, which is put on a head of a wig wearer, from above. Further, the apparatus for wearing a wig is excellent in fitness, and that does not cause pain in the attaching/detaching operation or for a long-time use.
  • an apparatus for wearing a wig includes a base sheet, a plurality of monofilaments in the form of projection disposed on a first side of the base sheet, each having a stalk extending from the base sheet and a big head on the top of the stalk, and an adhesive layer applied on a second side of the base sheet for bonding to the inside of the wig base, whereby the plurality of monofilaments gets entangled and hooked with natural hair of the wearer in wearing the wig and this state of entanglement is kept by hooking force.
  • a film having a larger coefficient of friction as compared with a material of the plurality of monofilaments may be applied on the surface of the monofilaments.
  • a peeling force in detaching the apparatus for wearing a wig from the head of the wig wearer is in the range of not less than 0.29 N (30 gf) to not more than 0.98 N (100 gf)
  • the deflecting force of the monofilaments in the vicinity of their tops is in the range of not less than 1.91 N (195 gf) to not more than 6.08 N (620 gf)
  • the deflecting force of the monofilaments in the vicinity of their bottoms is in the range of not less than 3.73 N (380 gf) to not more than 8.14 N (830 gf)
  • a disposal density of the monofilaments is in the range of not less than 50 pieces/cm 2 to not more than 120 pieces /cm 2 .
  • the height of the stalk of each of the monofilaments is set to be not less than 3 mm and not more than 6 mm
  • the diameter of the stalk of each of the monofilaments is set to be not less than 0.1 mm and not more than 0.5 mm
  • the diameter of the big head of each of the monofilaments is set to be not less than 0.2 mm and not more than 1 mm.
  • the apparatus for wearing a wig according to the present invention is bonded to the inside of the wig base with the adhesive layer applied on the second side of the base sheet, and the monofilaments project toward the head.
  • the wig is put on the head of the wearer, and light pressing force is applied thereon, the natural hairs of the wig wearer and the monofilaments are aligned in the inserting direction to each other.
  • the insertion is further advanced, the natural hairs are bent toward the lateral direction, whereby the monofilaments deflect in the direction substantially parallel to the base sheet or in the direction of the base sheet in the form of U shape or J shape to thereby get entangled with the natural hair of the wearer.
  • the monofilaments may be surely entangled to prevent the entanglement from being loosed or from being released by irregularly providing the monofilaments to the base sheet, or applying a film having a larger coefficient of friction as compared with a material of the monofilaments on the surface of the monofilaments.
  • the friction force may be increased to enhance a fixing strength by applying an elastomer solution having a friction coefficient larger than that of the monofilament to form a film.
  • the thickness of the film covering the surface of the monofilament is preferably not more than 10 ⁇ m.
  • the film on the stalk and the film on the head of the stalk become too thick to decrease the gap between the monofilaments.
  • the natural hairs cannot go in between the monafilaments, so that the natural hairs are pressed by the head of the stalk, which makes it difficult for the monofilaments to entangle with the natural hair.
  • the elastomer solution a 5 wt% solution obtained by dissolving a pellet of a styrene-based thermoplastic elastomer, specifically Quintac QTCSL-125 by Zeon Corporation, into toluene can be applied to the monofilaments.
  • the monofilament of the apparatus for wearing a wig has flexibility to some extent for getting entangled with the natural hairs of the wig wearer. Because of this flexibility, the stalk of the monofilament suitably deflects, whereby the big head on the top of the stalk get entangled and hooked with the stalk or the big head of other monofilaments, and the natural hairs get entangled between the monofilaments. This entanglement is kept. Accordingly, the monofilament of the apparatus for wearing a wig needs suitable flexibility. When the flexibility is low, the monofilaments do not deflect, so that the monofilaments might damage the head skin. When the flexibility of the monofilament is too high, the monofilaments get entangled with the natural hairs more than necessary, and thus the natural hair is pulled to cause pain in detaching the wig. Accordingly, the monofilament needs appropriate flexibility.
  • An apparatus for wearing a wig has a structure in which a plurality of monofilaments, each having a predetermined shape, flexibility, and size, are disposed on a base sheet in the form ofprojection, wherein a wig can surely be attached to the head of the wig wearer only by lightly pressing the wig, which is put on the head of the wig wearer, from above. Accordingly, the apparatus is suitable for an elderly person having weak finger strength or a person who cannot freely use his/her fingers, Further, the wig can be attached without being lifted up from the head of the wearer, whereby the apparatus is excellent in fitness, and does not cause pain in the attaching/detaching operation and for a long-time use.

  • FIG. 7(b) shows the case in which the portion in the vicinity of the bottom of the base of the stalk 22a of the monofilament 22 was deflected.
  • the tester described below was used.
  • Example 1 exhibited the most satisfactory result in attaining the object of the present invention.
  • Example 2 exhibited the satisfactory result in attaining the object of the present invention.
  • the flexibility of the monofilament 22 in Comparative Example 1 was lower than that of the monofilament 22 in Example 1 and Example 2, i.e., the monofilament 22 in Comparative Example 1 was more rigid. Therefore, the force causing deflection in the vicinity of the bottom of the head 22b on the top of the stalk 22a of the monofilament 22 was 6.19 N (632 gf), and the force causing deflection in the bottom of the base of the stalk 22a of the monofilament 22 was 8.26 N (843 gf).
  • the monofilaments 22 Since the rigidity of the monofilaments 22 was too high, the monofilaments 22 might not sufficiently deflect when the monofilaments 22 were brought into contact with the head skin of the wig wearer and thus, the monofilaments 22 might damage the head skin. Further, the monofilaments 22 could not get sufficiently entangled with the natural hairs, thereby entailing a problem that a predetermined fixing strength could not be obtained. This is because the deflecting force is high, i.e., the monofilaments 22 are rigid, due to the large diameter and small height of the stalk.
  • the flexibility of the monofilament 22 in Comparative Example 2 was higher than that of the monofilament 22 in Example 1 and Example 2, i.e., the monofilament 22 in Comparative Example 2 was flexible. Therefore, the force causing deflection in the vicinity of the bottom of the head 22b on the top of the stalk 22a of the monofilament 22 was 1.9 N (194 gf), and the force causing deflection in the bottom of the base of the stalk 22a of the monofilament 22 was 3.71 N (379 gf). Since the monofilaments 22 were too flexible, they got entangled with the natural hairs more than required. Therefore, the peeling force in detaching the wig becomes high, whereby the wig could not be detached easily. This is because the deflecting force is low, i.e., the monofilaments 22 are flexible, due to the small diameter and great height of the stalk.
  • Comparative Example 4 the disposal density of the monofilaments 22 in Comparative Example 2 was decreased.
  • the force causing deflection in the vicinity of the bottom of the head 22b on the top of the stalk 22a of the monofilament 22 was 1.56 N (159 gf)
  • the force causing deflection of the stalk 22a of the monofilament 22 was 3.37 N (344 gf). Since the flexibility was further high, i.e., more flexible than that in Comparative Example 2, the satisfactory result could not be obtained.
  • the film in Example 1 is in 10 ⁇ m, while the film in Comparative Example 9 is in 15 ⁇ m. Therefore, the friction coefficient increased, and thus the peeling force became not less than 0.98 N (100 gf), which means that a strong force was needed to detach the apparatus. Further, since the film applied on the stalk and the head was too thick, the gap between the monofilaments to each other was reduced. Therefore, the natural hairs could not go in between the monofilaments in attaching, but the natural hairs were pressed by the head of the stalk, which results in that it is difficult for the monofilaments to get entangled with the natural hairs.
  • the deflecting force on the top of the monofilaments of the apparatus for wearing a wig is preferably set in the range of not less than 1.91 N (195 gf) to not more than 6.08 N (620gf), more preferably set in the range of not less than 2.96 N (302 gf) to not more than 5.51 N (562 gf), and further preferably set in the range of not less than 4.01 N (409 gf) to not more than 4.94 N (504 gf).

  • the peeling force of the apparatus for wearing a wig 20 was measured.
  • the test was carried out in such a manner that test pieces, respectively having monofilaments 22 varying in height and diameter of the stalk, diameter and shape of the head, flexibility, and disposal density, were attached to the hairs 14 of the mannequin 13 for getting the monofilaments 22 entangled with the hairs 14, the tester 10 was coupled to test pieces in the vertical direction, and the tester 10 was pulled in the vertical direction with speed of 2 cm/second to 3 cm/second so as to measure the maximum force in the period until test pieces are completely detached from the hairs. The measurement was carried out five times for each test piece, and the average value was obtained.
  • the fixing force of the apparatus for wearing a wig 20 was measured. The test of the fixing force was carried out in the same manner as in the test of the peeling force except that the tester was coupled to test pieces in the horizontal direction and then pulled in the vertical direction.
  • Example 1 in the present invention was 0.79 N (81 gf), which is the most satisfactory result in attaining the object of the present invention.
  • the peeling force in Example 2 was 0.63 N (64 gf), which is lower than the peeling force in Example 1 since the monofilaments were aligned. However, this result was satisfactory in attaining the object of the present invention.

  • Comparative Example 2 an extreme change was recognized, such as from 1.20 N (122 gf) to 0.17 N (17 gf), since the entanglement between the stalks was caused due to the small diameter and large height of the stalk 22a, which means that the durability was remarkably deteriorated.
  • Comparative Example 1 only a slight change was recognized, such as from 0.28 N (29 gf) to 0.27 N (28 gf), since the diameter of the stalk 22a was large and the height thereof was small.
  • this test piece originally has a very small peeling force, which means that the entanglement with the natural hairs is insufficient, which result in that it cannot be put to practical use as described above. Accordingly, the diameter and height affect durability, and thus the stalk 22a are required to be set to a predetermined diameter and height.
  • a wig can surely be worn on a head only by lightly pressing the wig, which is put on the head of a wig wearer, from above, and a strong force is not needed in detaching the wig. Therefore, the present invention can provide an apparatus for wearing a wig suitable for use by an elderly person having weak finger strength or a person who cannot freely use his/her fingers.
