JP5771382B2 - Recyclable disposable wig - Google Patents

Description

  The present invention relates to a disposable wig, and particularly to a reusable disposable wig that can be reused.

  Wigs, for example wigs worn on the head, are used every day and therefore deteriorate over time.

  Since wigs manufactured by popular manual planting are very expensive at several hundred thousand yen, they are often used as they are even if they deteriorate somewhat over time, such as discoloration or hip breaks. For this reason, since it becomes easy for a user who has a complex to wear even if it deteriorates, it becomes clear that it is a wig when it deteriorates.

  Therefore, wigs proposed by the applicant of the present application that can be disposable for commercialization are gaining popularity not only in Japan but also overseas.

  An example of this disposable wig is Japanese Patent No. 4009910.

  Since this kind of disposable wig is directly attached to the human skin, there is a restriction that the adhesive strength cannot be increased. The reason for this is that if the adhesive strength is increased, as shown in FIG. 21, the horny layer 8a of the human skin, for example, the scalp 8, may be peeled off at the time of replacement.

  Therefore, the product will have a relatively weak adhesive strength. However, this has difficulty in durability.

Patent No. 4009910

  An object of the present invention is to provide a product that can overcome the above-mentioned difficulties and can withstand relatively long-term use while being a disposable wig.

  Another object of the present invention is to substantially extend the durability of the wig product by separating the reusable part from the disposable part and allowing the former to be reused.

In order to achieve the above object, the recyclable disposable wig according to the present invention comprises an A layer having a hairline part, a B layer having a wig body part, and the B layer interposed between the A layer and the B layer. An adsorbing layer that is detachably fixed to the A layer. The A layer is a base made of an extremely thin and moisture-permeable film material, and a first adhesive layer that is formed on the entire back surface of the base and is attached to the human body. And a hair material planted on the hairline portion formed at one end of the base, and the B layer is formed on the entire back surface of the base made of an extremely thin and moisture-permeable film material. A second adhesive layer; a tank layer formed on the entire back surface of the second adhesive layer; a release layer that is releasably interposed between the second adhesive layer and a part of the tank layer; and the base. Each of the above parts consists of hair material planted throughout A multilayer structure having a substantially two-dimensional shape in which the first adhesive layer, the base of the A layer, the adsorption layer, the tank layer, the release layer, the second adhesive layer, and the base of the B layer are laminated in this order. It is formed as follows.
The recyclable disposable wig according to claim 1, wherein the B layer is separated from the adsorbing layer integrally bonded to the A layer in the tank layer at the time of replacement.
Further, in the recyclable disposable wig according to claim 1, a peeling piece is interposed between the B layer and a part of the adsorption layer.
Further, in the remanufacturable disposable wig according to claim 3, the peeling piece is provided at an end portion on the opposite side of the hairline portion.
The recyclable disposable wig according to claim 1, wherein the first pressure-sensitive adhesive layer has a lower adhesive strength than the second pressure-sensitive adhesive layer and has a gelation degree smaller than that of the second pressure-sensitive adhesive layer. It is characterized by comprising.
The recyclable disposable wig according to claim 1, wherein the tank layer is made of the same film material as the base.
Moreover, in the remanufacturable disposable wig according to claim 1, the hair material is provided with a root portion to be planted proximally in close contact with one surface of the base, and a free end portion appears on the other surface side. To do.
In the recyclable disposable wig according to any one of claims 1 to 7, the B layer is first wrinkled on the tank layer and second wrinkled on the second adhesive layer at the time of replacement. It is characterized in that it is formed as a substantially three-dimensional multilayer structure.
The recyclable disposable wig according to claim 8, wherein the multilayer structure is formed in a layered portion where the release layer is stacked.

  In the present invention, the A layer having the hairline part and the B layer having the wig main body part can be separated, and most of the hair material constituting the wig can be planted in the B layer, and the A layer is not directly in contact with the human skin. Affix on the layer. On the other hand, the portion that deteriorates relatively quickly because it is in direct contact with the human skin is directly applied to the human skin as an A layer composed of a small amount of hair material. Therefore, the deterioration of the main body having most of the hair material constituting the wig becomes relatively slow, so that it can be reused, and the durability of the wig is greatly improved.

  On the other hand, since the A layer has a single-layer structure, there are almost no steps from the human skin, and the appearance is natural and the appearance is greatly improved. That is, when the hairline has a multi-layer structure, the level difference from the human skin is too conspicuous, and it is possible to prevent unnaturalness and a significant reduction in appearance.

  Further, since the main body portion has a three-layer structure including the bases of the A layer and the B layer and the tank layer interposed between the bases, there is an effect of preventing physical deformation and damage from external factors.

  Further, the main body portion has a three-layer adhesive layer, which absorbs moisture such as sweat from the human skin. Since the absorbed moisture moves from the lower layer to the upper layer, the lowermost adhesive layer in direct contact with the human skin can prevent deterioration of the adhesive strength.

  Next, the wig according to the present invention will be described in more detail with reference to the drawings showing embodiments. For convenience, portions having the same function are denoted by the same reference numerals and description thereof is omitted. 2, 4, 17 and 18, and FIGS. 5 (A) to 5 (I) and FIGS. 14 (A) to 14 (I), the hair material 9 is schematically shown because it is represented schematically. Less than the number is displayed.

  The wig 1 according to the present invention includes an A layer 3 having a hairline part 4, a B layer 5 having a main body part, and an adsorption layer 7.

  The A layer 3 is formed on an A layer sheet 11 including a base 14, a first adhesive layer 15, and a film separator. A hairline 4 of the wig 1 is formed on the A layer 3. That is, the hair material 9 is planted in the front portion of the A layer sheet 11 leaving the blank portion 12 a to form the hairline portion 4 of the wig 1. A space portion 12b is formed in the remainder of the A layer sheet 11, and the B layer 5 is attached. In the case of this example, the hair material 9 planted in the A layer 3 is about 7% of the hair material 9 planted in the wig 1.

The base 14 is made of an extremely thin and moisture-permeable film-like material such as polyurethane having a thickness T ₁ of about 30 μm, for example.

  The hair material 9 is made of polyester fiber, and a root portion 9a that is a planting base end is provided in close contact with the back surface of the base 14 so that a free end portion appears on the surface side of the base 14. The hair material 9 is randomly planted on the base 14. In the hair material 9, a root portion 9a planted on the base 14 is fixed in a spot shape by an ultraviolet curing agent 9b.

The first adhesive layer 15 is formed on the entire back surface of the base 14 with a uniform thickness from above the ultraviolet curing agent 9b. The first pressure-sensitive adhesive layer 15 is a pressure-sensitive adhesive mainly composed of a mixture of silicon and acrylic, and is made of a so-called soft pressure-sensitive adhesive that has a relatively weak adhesive force and a relatively low degree of gelation. The thickness T ₂ is formed to be about 60 μm which is twice the thickness of the base 14.

  Reference numeral 17 denotes a film separator made of polyethylene terephthalate (PET), which is detachably attached to the back surface of the first adhesive layer 15.

  The B layer 5 is formed on a B layer sheet 21 including a base 23, a second adhesive layer 25, a release layer 27, and a tank layer 29.

  That is, the B layer 5 serves as a wig main body, and an appropriate margin 13a is left in the center of the B layer sheet 21, and the hair material 9 is planted on the base 23 of the center. In the case of this example, the hair material 9 planted in the B layer 5 is about 93% of the hair material 9 planted in the wig 1.

The base 23 is made of an extremely thin and moisture-permeable film-like material such as polyurethane having a thickness T ₃ of about 30 μm, for example.

  The hair material 9 is made of polyester fiber, and a root portion 9a that is a planting base end is provided in close contact with the back surface of the base 23, and a free end portion is exposed on the surface side of the base 23. The hair material 9 is randomly planted on the base 23. In the hair material 9, the root portion 9a planted on the base 23 is fixed in a dot shape by the ultraviolet curing agent 9b.

The second adhesive layer 25 is formed on the entire back surface of the base 23 with a uniform thickness from above the ultraviolet curing agent 9b. The second adhesive layer 25 is an adhesive mainly composed of a mixture of silicon and acrylic, and is composed of an adhesive having a so-called hard property that has a relatively strong adhesive force and a relatively high degree of gelation. The thickness T ₄ is formed at about 60 μm, which is twice the thickness of the base 23.

The tank layer 29 is made of the same film material as the bases 14 and 23, for example, polyurethane, and has a thickness T ₅ of about 30 μm, which is the same thickness as the bases 14 and 23, and the second adhesive layer 25 and the adsorbent layer. 7 are stacked next to each other and bonded to a sandwich structure.

  31 is an adsorption sheet and provides the adsorption layer 7 forming the third adhesive layer.

  A separator 33 made of polyethylene terephthalate (PET) is detachably attached to the surface of the adsorption sheet 31 and a separator 35 made of paper is detachably attached to the back surface.

  The adsorbing layer 7 is a pressure-sensitive adhesive composed of a mixture of silicon and acrylic as a main component, and is composed of a so-called soft pressure-sensitive adhesive having a relatively weak adhesive force and a relatively low degree of gelation.

  10 is a peeling piece for paste killing, and is made of a 30 μm-thick polyurethane film having the same effect as the base 14 (shown in FIG. 4). The peeling piece 10 is attached to the rear end portion of the adsorption layer 7 as described later.

Here, the degree of adhesive strength (peeling adhesive strength) will be described. The adhesive force of the second adhesive layer 25 and the adsorption layer 7 is about 16.5 N / 20 mm width, and the adhesive force of the first adhesive layer 15 is about 3 N / 20 mm width. The measured value of this adhesive strength refers to the adhesive strength to the test plate in accordance with JIS Z 0237, paragraph 10 (adhesive strength), whereas the adhesive strength of the above JIS measures the test plate as a stainless steel (SUS) plate, In the present invention, a bakelite plate is used as a test plate. “Gelification” means that the adhesive component of the pressure-sensitive adhesive changes to a semi-solid state, and a specific index is difficult to measure, although it refers to JIS Z 0237 item 13 (holding force). The relative evaluation between the second adhesive layer 25 and the first adhesive layer 15 is used.

<Installation procedure>
Next, a procedure for attaching the wig 1 according to the present invention will be described.

(1) Initial mounting procedure <Pre-processing>
<1> The separator 35 attached to the back surface of the suction sheet 31 is peeled off, and the suction sheet 31 is attached to the surface of the A layer sheet 11 and integrated. Thereby, both sides of the A layer 3 are of the adsorption type (FIG. 5A).

<2> Next, only the blank portion 13a formed at the front portion of the B layer sheet 21 is cut along the joint line 19a of the A layer 3 (FIG. 5B). Reference numeral 19b denotes a joint line of the B layer 5 after being cut so as to correspond to the joint line 19a.

<3> Next, the mold 6 taken from the user's use site is applied to the back surface 11a of the A layer sheet 11 (that is, the back surface 17a of the film separator 17), and the positioning line 6a is marked (FIG. 5C).

<4> Next, the A layer sheet 11 is fixed to the work table 61, and a part of the separator 33 on the surface 31a of the adsorption sheet 31 attached to the surface of the A layer sheet 11, that is, the integrally attached sheet 31 is peeled off (FIG. 5D )). This peeling is aimed at one third of the whole from the front.

<5> Next, the front part of the B layer sheet 21 is attached to the A layer sheet 11 (FIG. 5E). At this time, the joint line 19b of the B layer sheet 21 is made to correspond firmly to the joint line 19a of the A layer sheet 11 so that no gap is generated.

<6> Next, the unattached portion 21a of the B layer sheet 21 is turned up to the front portion and stopped by the locking tool 63. Subsequently, all the separators 33 of the suction sheet 31 integrated with the A layer sheet 11 are peeled off (FIG. 5F).

<7> Next, the peeling piece 10 of the paste-killing film is attached to the rear portion of the positioning line 6 a displayed on the suction sheet 31 integrated with the A layer sheet 11. This peeling piece 10 may stick out by sticking out from the positioning line 6a (FIG. 5 (G)).

<8> Next, the unattached portion 21a of the B layer sheet 21 is attached to the upper surface of the A layer sheet 11 whose surface is exposed, that is, the surface of the suction sheet 31 that is integrally attached (FIG. 5G). . At this time, the B layer sheet 21 is pulled too much so that the B layer sheet 21 is not excessively tensioned.

<9> Next, the A layer sheet 11 is removed from the work table 61, and the positioning line 6a is again provided on the back surface 11a of the A layer sheet 11 in accordance with the mold 6 in order to confirm that there is no deviation from the display in step <3>. Redraw (FIG. 5 (H)).

<10> Subsequently, the blank portions 12a and 13a are cut in accordance with the line in which the hair material 9 is planted. As a result, the A layer sheet 11 and the B layer sheet 21 are entirely bonded via the adsorption layer 7, and the pretreatment is completed (FIG. 5I). At this time, a peeling piece 10 is interposed between the adsorption layer 7 integrated with the A layer 3 and the B layer 5.

<Installation method>
Next, a method for mounting the wig 1 on which the pretreatment has been completed to the human body, for example, the scalp 8, will be described with reference to FIGS.

<11> First, the hairline part 4 of the wig 1 according to the present invention is aligned with a predetermined position of the scalp 8, and then a part (not shown) of the film separator 17 on the back surface is peeled off and cut to adhere the hairline part 4 The first half layer 15a is applied to the scalp 8 (FIG. 6).

<12> Next, the remaining film separator 17b is peeled off, and the rear half 15b of the adhesive layer 15 is attached to the scalp 8 (FIGS. 7 and 8). As a result, the entire A layer 3 is affixed to the scalp 8.

<13> Next, the process proceeds to the wrinkling step. This is performed for the B layer 5. As shown in FIG. 8, after attaching the latter half 15 b of the adhesive layer 15 to the scalp 8, the latter half 23 b of the base 23 is raised from the release layer 27, and a small wrinkle is attached to the tank layer 29. As a result, primary wrinkles 29a are formed in the tank layer 29 (FIGS. 9A, 9B, and 10).

  The primary wrinkling is performed to make the two-dimensional multilayer structure into a spherical shape that roughly corresponds to the scalp shape of a specific user. Since the primary wrinkle 29a is naturally formed along the scalp shape because the material composed of the tank layer 29 and the adsorption layer 7 is extremely thin, the number of wrinkles is arbitrary. In the case of a plurality of wrinkles, as shown in FIG. 9A, it is not hindered from being generated in the entire region of the back of the head.

  As shown in FIG. 9 (B), the primary wrinkle is formed by properly standing up a laminated body composed of the adsorbing layer 7 and the tank layer 29 and adhering them to form a primary wrinkle 29a. The adhering layer 7 is stuck to the scalp 8 in this state by laying and adhering 29a to the adjacent part (FIGS. 9A and 9B). The primary wrinkling is performed in a portion where the release layer 27 is interposed, in the case of the illustrated example, in the region of the back of the head.

<14> Next, the release layer 27 is peeled off (FIG. 11). As a result, the second adhesive layer 25 is exposed. At this time, the adsorption layer 7 and the tank layer 29 remain attached to the scalp. In this state, “secondary wrinkling” is performed (FIG. 12). Reference numeral 30 denotes a secondary wrinkle formed by secondary wrinkling.

  The secondary wrinkling is performed in order to match the user's scalp shape accurately with the multilayer structure having a spherical shape that roughly corresponds to the user's scalp shape. As a result, the flow of the hair material 9 can be accurately applied, resulting in a more natural feeling and a good appearance.

  As shown in FIG. 12 (B), the secondary wrinkling is a laminate composed of the second pressure-sensitive adhesive layer 25 to be wrinkled, that is, the second pressure-sensitive adhesive layer 25, the root 9a and the hair material bonded thereto. The secondary wrinkle 30 is formed by standing and adhering a laminated body composed of the base 23 planted with 9.

  The number of secondary wrinkles 30 can be one or more. In the case of a single piece, the vicinity of the central part of the occipital region is desirable. Further, it is desirable to form the secondary wrinkled portion different from the primary wrinkled portion 29a.

<15> Next, the second adhesive layer 25 is stuck on the tank layer 29 in a state of being secondarily wrinkled (see FIG. 12A).

<16> Next, the secondary wrinkle 30 made of the above-mentioned laminated body such as the second adhesive layer 25 and the like adhered by cutting is cut from the vicinity with the hair material 9 planted (FIG. 13). The cut line C is shown in FIG. That is, what is cut is above the tank layer 29 (a laminated body of the base 23 of the B layer and the second adhesive layer 25), and the base 14 and the tank layer 29 of the A layer that are the ground are not cut.

<17> Next, the hair material 9 is appropriately ironed and blended with the ground hair. Thereby, the wearing of the wig 1 is completed.

<18> Thus, the wig is customized to a three-dimensional shape that matches the scalp shape of the specific user, and the customized wig 2 is formed.

(2) Second and subsequent mounting methods When a predetermined period (for example, 3 to 4 months) has passed and the battery has deteriorated, it will be reused. Next, the mounting procedure will be described.

<Removal>
<1> First, the B layer 5 is peeled off from the A layer 3 from the part of the peeling piece 10 (shown in FIGS. 4 and 10) attached to the rear part of the wig 1, and the B layer 5 is rolled up.

  Since the peeling piece 10 is made of a polyurethane film that can be easily peeled off, it is easy to separate the B layer 5 from the adsorption layer 7. On the other hand, since the peeling piece 10 is a small piece, it does not affect the fixing of the B layer 5 to the adsorption layer 7 when the wig is used.

<2> Next, the A layer 3 is peeled off from the scalp 8 (not shown).

<3> It should be noted that the user's deposition site is treated with a trimmer. Further, the removed B layer 5 is washed for reuse.

<Pretreatment>
<4> Next, the mold 6 is applied to the back surface 11a ′ of the new A layer sheet 11 ′ to mark the positioning line 6a (FIG. 14A).

<5> Next, a new adsorbing sheet 31 ′ is integrally attached to the new A layer sheet 11 ′ to make the new A layer sheet 11 ′ a double-sided adsorbing type (FIG. 14B).

<6> Next, only the blank portion 12 ′ formed at the front portion of the new A layer sheet 11 ′ is left and the remaining blank portion is cut to form a new A layer 3 ′ (FIG. 14C). .

<7> Next, the film separator 33 ′ on the surface of the new A layer 3 ′, that is, the surface of the adsorbing layer 7 ′ integrally attached is peeled off (FIG. 14D).

<8> Next, after attaching a new release piece 10 'as a paste-killing film to the rear part of the new A layer 3', a working wrap 20 is attached from above (FIG. 14E).

<9> Next, the B layer 5 to be reused is pasted on the new A layer 3 '(FIG. 14F). In this case, as described in the initial mounting procedure, the joint line 19b at the tip of the B layer 5 to be reused is aligned with the joint line 19a of the A layer 3 'so that no gap is generated.

<10> Next, the front blank portion 12 ′ of the new A layer 3 ′ is cut out, and the portion protruding from the positioning line 6 a is cut out as appropriate, and the pre-processing for reuse ends (FIG. 14G). ).

<Installation method>
<11> First, a part of the film separator 17 ′ on the back surface of the hairline 4 ′ of the new A layer 3 ′ is cut and attached to the hairline of the scalp 8 (see FIG. 6).

<12> Next, the non-attached portion of the B layer 5 to be reused is stopped by the locking tool 63 so as not to obstruct, and the remaining film separator 17 ′ of the new A layer 3 ′ is peeled off, and the scalp 8 (see FIG. 7). (FIG. 15 (H)).

<13> Next, the wrap 20 is carefully peeled off from the surface of the new A layer 3 ′, and the remaining B layer 5 is attached to the exposed adsorption layer 7 ′. At this time, since the B layer 5 has already been wrinkled, no wrinkling work is required (FIG. 15I).

<14> Next, the hair material 9 is appropriately ironed and blended with the ground hair. This completes the mounting.

  The wig according to the present invention is particularly effective when applied to a part lacking its own hair. When applying to the part where the own hair exists, it is desirable to excise the own hair existing in the part.

  According to the present embodiment, the following operational effects are obtained.

<1. Simultaneous achievement of improved durability and improved appearance>
First, since the A layer that is directly attached to the human skin and the B layer that is not in direct contact with the human skin can be separated, the A layer that deteriorates relatively quickly is made disposable, and the B layer that deteriorates relatively slowly is reused. Can be possible. In the case of the present embodiment, the B layer occupies most of about 93% of the entire wig, so that the durability of the disposable wig is greatly improved.

  If the hairline has a multi-layer structure, the level difference from the human skin is too conspicuous, which makes it unnatural and greatly reduces the appearance. Therefore, the durability improvement and the appearance improvement are self-contained. In the wig according to the present embodiment, since the A layer is a single layer structure, there is almost no step with the human skin and it feels natural. The appearance is greatly improved. Therefore, it is possible to achieve both improvement in durability and improvement in appearance.

The wig main body is composed of a base 23, a tank layer 29 made of the same film material as the base 23, and an A-layer base 14, and has a three-layer structure. Therefore, there is an effect of preventing physical deformation and damage from external factors.

  The wig body has a three-layered adhesive layer, which absorbs moisture such as sweat from the human skin. Since the absorbed moisture moves from the lower layer to the upper layer, the lowermost adhesive layer in direct contact with the human skin can prevent deterioration of the adhesive strength. Since the B layer 5 having the main body occupies most of the entire wig, the effect of maintaining the adhesive strength of the adhesive layer greatly contributes to the durability of the entire wig.

  Here, the peeling piece 10 will be described. In the present embodiment, the peeling piece 10 is provided at the rear part. This may cause a so-called “sagging” phenomenon in which the shape of the film of each part of the A layer and the B layer changes when a force is excessively applied in the separation operation at the time of removal. If this occurs, the joint lines 19 and 19 'will not match exactly. If the peeling piece 10 is provided in the rear part, it is convenient in considering the right and left balance when performing the separation operation, and the possibility of such an accident is minimized. For example, if it is provided on the left and right temporal scalp, there is a high possibility that the user will touch while wearing, and there is a relatively high risk of accidents due to hooking during wearing. Therefore, in order to prevent such an unexpected situation, and considering the balance during the separation operation, the rear part of the peeling piece 10 is installed.

<2. Just fit>
Once the wig according to the above embodiment is customized to the shape of the scalp of a specific user, not only the attachment to the scalp is due to the adhesive strength of the A layer adhesive layer 15, but also a three-layer multilayer structure is fitted to the scalp. Since this is a state, this physical force also contributes to wearing. Therefore, even if the adhesive strength of the first adhesive layer 15 is relatively weak or somewhat weak, and even if there is some vellus hair on the mounting surface, it can be reliably attached and prevent unintentional detachment. Can do.

  This just fit property can further weaken the adhesive force of the first adhesive layer 15 that is directly adhered to the human body, thereby reducing the burden on the skin.

  In addition, since the wrinkling performed to customize the scalp shape of a specific user is divided into two stages of primary and secondary, the customization work can be performed more accurately and quickly by simplifying the work. .

  The wig according to the above embodiment is just fit to the scalp shape of a specific user, thus preventing the generation of abnormal noise, intrusion of water, dirt, etc., greatly improving the feeling of use and good durability It can be.

<3. Permeability effect, etc.>
The wrinkling is divided into two stages of primary and secondary, and the wrinkled portion is cut off in the secondary wrinkling, so that no unnecessary portion protrudes from the surface of the multilayer structure. Therefore, since the “separation” due to the generation of wrinkles does not occur in the base film, the light transmittance with respect to the base becomes very good. As a result, it becomes difficult to distinguish between the human skin and the base 14 of the hairline part 4, and a more natural appearance is obtained.

  Moreover, since there is no protrusion of an unnecessary part on the surface of the multilayer structure, the flow of the hair material 9 is not changed by wrinkles and becomes constant, and the appearance feeling is further improved.

  Since the wrinkled wrinkles are cut and the wrinkled hair material portion does not protrude, it becomes possible to create a wig with short hair that was impossible when wrinkled. Furthermore, since it is not limited to a specific hairstyle, the variation of a wig increases.

<4. Responsiveness>
In conventional wigs, customizing the shape of the scalp of a specific user requires about 40 days at the earliest through the steps of mold making, base manufacturing, and flocking. However, since the wig according to the present embodiment can be manufactured in advance as a general-purpose wig of a two-dimensional shape corresponding to any user and customized to the scalp shape of a specific user at the site, it can be handled on the same day. it can.

  Therefore, it contributes to rapid delivery and cost reduction.

<5. Adhesive retention by surface adhesion>
In the present embodiment, the first adhesive layer 15 has a substantially flat surface due to the presence of the adsorption layer 7, the tank layer 29, and the release layer 27 (see FIG. 4). In addition, since the tank layer 29 is made of a moisture-permeable material, it absorbs sweat and the like generated during wearing on the scalp 8, thereby further reducing the tendency to protrude into the first adhesive layer 15 due to the presence of the root portion 9a. Therefore, the first adhesive layer 15 can be adhered to the scalp 8 in a planar shape (see FIG. 16), and the adhesive force is maintained for a long time despite being a weak adhesive.

  With regard to this point, the gelling component in the first adhesive layer 15 is easily gelled and the molecular structure of the adhesive is destroyed when moisture in the sweat moves to the first adhesive layer 15. Power becomes too strong. However, according to the present embodiment, since the tank layer 29 is interposed between the adsorption layer 7 and the second adhesive layer 25, the gelation is prevented from being transferred, so that a weak adhesive force is maintained for a long time. It is.

  From a microscopic point of view, as shown in FIG. 16, the scalp 8 has a slight unevenness, but since the surface to be bonded to the surface is an extremely thin multilayer structure, the adhesive surface becomes an uneven surface of the scalp 8. Correspondingly, it can be adhered freely, so that it can be adhered to the entire surface of the scalp 8 to be mounted.

  Therefore, the wig 1 according to the present embodiment is adhered to the entire surface of the scalp 8 even if the adhesive strength of the adhesive bonded to the scalp 8 is relatively weak, so that the adhesive holding force is maintained and the unexpected fall off is prevented. be able to. In this regard, as shown in FIG. 17, since the adhesive holding force is not maintained if the first adhesive layer 15 ′ is bonded only to the scalp 8 in the form of dots S, the adhesive of the first adhesive layer 15 ′ is conventionally maintained. If the force is not composed of an adhesive having a relatively strong and hard property, there is a risk of accidental dropping. However, if the adhesive force of the first adhesive layer 15 ′ is composed of a relatively strong and hard adhesive, a very large amount of the stratum corneum 8 a of the scalp 8 is peeled off as shown in FIG. 19.

  In addition, the presence of moisture such as sweat adversely affects the adhesive force. Since the sweat and the like soaked into the first adhesive layer 15 are absorbed by the adsorption layer 7, the tank layer 29 and the base 23, the first adhesive layer 15. Is less affected by moisture such as sweat and maintains adhesive strength. Also by this, the adhesion to the scalp 8 by the first adhesive layer 15 having a relatively weak adhesive force is maintained.

  In removing the wig, in this embodiment, the first adhesive layer 15 adhered to the scalp 8 has a relatively weak adhesive force, so that the stratum corneum 8a of the scalp 8 is hardly peeled off as shown in FIG. That's it.

  In the present embodiment, since the adhesive strength of the first adhesive layer 15 is relatively weak, the stratum corneum 8a attached to the layer surface can be easily removed by washing with water. As a result, the adhesive surface can be activated, and can be used repeatedly (for example, about 30 times).

<6. Ease of handling>
A hair material 9 is planted on the bases 14 and 23, and the hair material 9 acts as a kind of core material. In addition, the adsorbing layer 7 is laminated and bonded by the bases 14 and 23 in which the hair material 9 is planted and the tank layer 29 made of the same film material as the bases 14 and 23 to form a sandwich structure. Therefore, since the reducing force by the adsorption layer 7 having a relatively strong adhesive force is regulated, the base 14 is prevented from being crumpled.

  In addition, since the tank layer 29 is made of the same film-like material as the bases 14 and 23, the compatibility with the pressure-sensitive adhesive is not unbalanced. In this respect, the bases 14 and 23 are prevented from becoming excessively reduced, In addition, a decrease in moisture hygroscopicity is prevented.

  Therefore, since the bases 14 and 23 are not shrunk, they are easy to handle when mounted by the user, and even if the bases 14 and 23 are subjected to a tensile load when they are removed, excessive extension is restricted, so that handling is easy. There is.

  Furthermore, in the second and subsequent attachments, as shown in FIGS. 20 and 21, if the central portion 2a of the multilayer structure protrudes downward, the adhesion surface to the skin can be visually recognized, so the attachment operation is very difficult. It will be easier. In this case, since the central portion 2a of the multilayer structure protrudes downward, the hair material 9 rises upward, and the wrapping of the hair material 9 at the time of wearing can be prevented. Therefore, the wearing operation of the wig becomes easy and quick, and the handling property is good.

<7. Ease of remake>
When the B layer 5 is reused, it is not necessary to remove the adhesive layer 25. Therefore, the reuse of the wig 1 is easy.

<8. Other effects>
Since the tank layer 29 is made of the same film material as the bases 14 and 23 and has the same thickness as the bases 14 and 23, the tank layer 29 is more permeable when worn on the scalp 8. Therefore, there is an effect that it is more difficult to distinguish the wigs from the bases 14 and 23. In this regard, if the tank layer 29 is made of a different material from the bases 14 and 23 or if the thickness thereof is excessively large, the permeability becomes unbalanced, and it is difficult to determine whether the tank layer 29 is a wig. .

  The present invention is not limited to the above embodiment. For example, the installation site | part of the peeling piece 10 or the peeling layer 27 is arbitrary. In addition, regarding the thickness of the peeling piece 10, the numerical values described in the above embodiment should be understood as examples. Further, the thicknesses of the bases 14 and 23 and the tank layer 29 can be made even thinner, for example, about 10 μm and 20 μm than the above embodiment. The application site is not limited to the head as long as it is human skin. Further, the first adhesive layer 15 of the A layer is composed of a so-called hard adhesive having the same effect as the second adhesive layer 25 of the B layer and having a relatively strong adhesive force and a relatively high degree of gelation. You can also. Furthermore, the wearing procedure of the wig 1 described in the above embodiment is an example, and the changing of the wearing order is allowed.

  The present invention can be used as, for example, a scalp wig.
