[0015] Hereinafter, the hair cap according to the present disclosure will be described based on the embodiment with reference to the drawings. In this specification and claims, the term "hair dye" is used as a general term for hair cosmetic agents that contain a bleaching agent without a dye. The terms "hair dye" and "hair dyeing" are used to include hair bleaching.

[0016] First embodiment: The hair cap 10 according to the first embodiment is used by a user who dyes his / her hair by putting it on the head. As shown in FIG. 1, the hair cap 10 according to the first embodiment is manufactured using a sheet 20 for a hair cap, which is made of a single sheet material. The sheet 20 for a hair cap is manufactured by cutting out the sheet material along the outline, that is, by die-cutting. The sheet 20 for a hair cap extends in the vertical direction connecting the head and shoulders of the user, and has a bilaterally symmetrical shape with the folding part 21 as the axis of symmetry. The sheet 20 for a hair cap includes a pair of a hair covering part forming part 22, a shoulder covering part forming part 23, and a chin strap part forming part 24. The shoulder covering part forming part 23 and the chin strap part forming part 24 are formed by cutting and separating the boundary 231 between the two parts, and branch off at the branching part 25. A fixed string part forming part 23a is formed in each of the shoulder covering part forming parts 23. The hair cap sheet 20 becomes the hair cap 10 having the head covering part 12 having the three-dimensional shape shown in FIG. 2 by welding the head welding part 22a.

[0017] 2 is a front view of the unfolded hair cap 10. The hair cap 10 is made of polyethylene resin, and low-density polyethylene (LDPE) or high-density polyethylene (HDPE) can be used. It is more preferable to use LDPE because it is highly flexible and easy to handle, and also because it is highly transparent, making it easy to check the hair in the desired position and to easily pierce it with a hair stick. The hair cap 10 includes a hair covering part 12, a shoulder covering part 13, and a chin strap part 14. The shoulder covering part 13 includes a fixing strap part 13a.

[0018] The hair covering part 12 is a part that covers the user's hair and is three-dimensionally molded into a hat shape. The shoulder covering part 13 is a part that covers the user's nape to shoulders and is integrally formed with the hair covering part 12. The hair cap 10 has a bilaterally symmetrical shape with the bent part 11 as an axis of symmetry, and is provided with a pair of chin strap parts 14 and fixing strap parts 13a on the left and right, respectively. Meanwhile, unlike the hair cap sheet 20, the hair cap 10 has one hair covering part 12 and one shoulder covering part 13.

[0019] The shoulder covering part 13 and the chin strap part 14 are formed so as to be separable from each other by cutting the sheet material at the boundary 131 between them as described above. As a result, the chin strap part 14 is formed extending from both front side surfaces of the hair covering part 12. The shoulder covering part 13 and the chin strap part 14 are branched at a branch part 15 forming the base end part of the chin strap part 14, and are separated into the shoulder covering part 13 and the chin strap part 14 from the branch part 15 toward the tip part of the chin strap part 14 and the lower end of the shoulder covering part 13. The branch part 15 (branch part 25 in FIG. 1) has an R shape. The R shape preferably has a curvature radius of 5 to 15 mm, for example, and more preferably has a curvature radius of 10 mm. The R shape in this embodiment means that the shape of the base end part of the chin strap part 14 does not have a corner shape where stress is concentrated, particularly a sharp corner shape, but has a curved shape. By avoiding the formation of stress concentration portions, when a user ties both chin strap portions 14 under the chin, the chin strap portion 14 is pulled, which causes stress to be applied to the branch portion 15, resulting in damage; more specifically, it is possible to prevent or suppress the chin strap portion 14 from tearing at the branch portion 15.

[0020] The fixing string portion 13a is used to fix the shoulder covering portion 13 in a folded state when the shoulder covering portion 13 is folded back toward the hair covering portion 12 after the hair is pulled out by the hair stick and the hair dye is applied thereto. The fixing string portion 13a is formed below the shoulder covering portion 13 and extends in a direction intersecting the top-bottom direction connecting the head and shoulders of the user. When the user is wearing the hair cap 10 on the head, the fixing string portion 13a has a shape that protrudes forward of the user. The base end portion 132 of the fixing string portion 13a, i.e., the portion where the fixing string portion 13a extends from the shoulder covering portion 13, has an R shape. The R shape preferably has a curvature radius of 30 to 50 mm, and more preferably has a curvature radius of 40 mm. The R-shape avoids the formation of stress concentration areas, and when the user ties both fixing string parts 13a around the forehead, the fixing string parts 13a are pulled, which causes stress and damage, and more specifically, prevents or suppresses the fixing string parts 13a from tearing at the base end 132.

[0021] As shown in FIG. 3, the hair cap 10 has a dimensional ratio a:b between the hair covering portion 12 and the shoulder covering portion 13. It is preferable that a:b=1:1 to 1:1.5. It is sufficient that the shoulder covering portion 13 can cover the entire hair covering portion 12 when folded back, and when the dimension b from the branching portion 15 is defined as the shoulder covering portion 13, this can be realized if it is equal to the dimension a of the hair covering portion 12. Also, from the viewpoint of providing some leeway for folding back and preventing or suppressing the hair dye from adhering below the shoulders, it is preferable that the dimension b is larger than the dimension a, that is, the ratio of a:b is greater than 1:1.

[0022] The manner of use of the hair cap 10 will be described below. First, as shown in Fig. 4, the user places the hair covering part 12 over the head 50. The shoulder covering part 13 covers the shoulder area 51. Next, as shown in Fig. 5, the user ties the pair of chin strap parts 14 under the chin 53 to fix the hair covering part 12 to the head 50. At this time, because the branch part 15 has an R-shape, it is possible to prevent or reduce the situation in which the base end of the chin strap part 14 is damaged at the branch part 15.

[0023] When the hair cap 10 is fixed to the user's head 50, the user uses a hair stick 60 to make holes in the hair cap 10 and pull out a portion of the hair that is desired to be dyed, as shown in FIG. 6. When all the desired hair is pulled out, the hair dye is applied to the pulled out hair. When the hair dye is applied to the hair, the user lifts the bottom of the shoulder covering part 13, as shown in FIG. 7, and the shoulder covering part 13 is folded back so as to cover the hair covering part 12 to which the dye is applied. With the shoulder covering part 13 folded back, the user ties the pair of fixing string parts 13a at the forehead 54, and fixes the shoulder covering part 13 in the folded back state. The hair exposed to the hair covering part 12 is covered by the folded back shoulder covering part 13, which prevents the hair from being warmed and dried, and promotes the bleaching and hair dyeing effect. In addition, the hair to which the hair dye has been applied is covered by the shoulder covering portion 13, thereby preventing or suppressing the hair dye from dripping down.

[0024] After a predetermined time required for dyeing has elapsed, the user unties the pair of fixed strings 13a, unties the pair of chin straps 14, and removes the hair cap 10 from the head 50. The user washes off the hair dye to obtain partially dyed or bleached hair.

[0025] A hair stick 60 that can be used with the hair cap 10 according to this embodiment has, for example, a shape shown in Fig. 8. A user can remove hair to be dyed or bleached from the hair cap 10 by inserting the hook-shaped tip 61 into a desired position on the hair cap 10, hooking it, and pulling it out. Note that the hair stick 60 shown in Fig. 8 is only one example, and hair sticks 60 having various other shapes can be used with the hair cap 10 according to this embodiment.

[0026] According to the hair cap 10 of the first embodiment described above, the hair cap 10 is provided with the shoulder covering part 13 connected to the hair covering part 12 and covering both shoulders, and the pair of chin strap parts 14 extending from both front side surfaces of the hair covering part 12, so that the hair cap 10 can be fixed to the head 50, and the usability of the hair cap 10 can be improved. As a result, the hair cap 10 is prevented from shifting when the hair stick 60 is used to pull out the hair, and the hair can be easily pulled out. In addition, the shoulder covering part 13 is provided with a pair of fixing strap parts 13a, so that the shoulder covering part 13 can be folded back and fixed in a state of covering the hair covering part 12. As a result, it is possible to cover the hair that has been taken out to the surface of the hair covering part 12 and to which a hair dye has been applied, which promotes the hair dyeing or bleaching effect and further improves the usability of the hair cap 10.

[0027] In other embodiments: (1) The hair cap 10 may be provided with position marks in advance to serve as targets for perforation positions. The position marks may include, for example, markings by color, area designation by perforation, etc. When the position marks are provided, the hair cap 10 may have low transparency and may be provided with various patterns.

[0028] (2) In the above embodiment, the hair cap 10 is manufactured using one hair cap sheet 20, but the hair cap 10 may be manufactured using two or more hair cap sheets by bonding, including welding. For example, half of the hair cap sheet 20 with the folded portion 21 as the welding portion may be cut out from a sheet material, and the half may be bonded at the folded portion 21 and the head welding portion 22a to manufacture the hair cap 10.

[0029] Although the present disclosure has been described above based on the embodiments, the above-described embodiments are intended to facilitate understanding of the present disclosure and are not intended to limit the present disclosure. The present disclosure may be modified or improved without departing from the spirit and scope of the claims, and the present disclosure includes equivalents thereof. [Explanation of symbols]
