However, in curling using a conventional hair holder, if the number of windings of the hair holder increases, the hair treatment agent hardly penetrates into the vicinity of the core in the wound hair holder, and the hair near the core It was difficult to provide a sufficient hair treatment agent. On the other hand, when the permeability of the hair treatment agent to the hair holder is improved, the hair treatment agent that has once penetrated into the hair holder may leak from the outer peripheral portion of the wound hair holder.
The above problem becomes particularly remarkable when the hair holding tool is used for a long hair bundle or a long hair bundle.

  Therefore, the object of the present invention is to allow the hair treatment agent to easily penetrate into the vicinity of the core of the wound hair holding device, and once penetrated into the hair holding device from the outer peripheral portion of the wound hair holding device. It is to provide a hair holder that is difficult to leak.

  The present invention comprises a flat tubular body constituted by a sheet so that a hair bundle can be inserted from an opening at one end toward an opening at the other end, and the basis weight of the sheet is from the opening at the one end. The object is achieved by providing a hair holder that gradually decreases toward the opening at the other end.

  According to the hair holding device of the present invention, the hair treatment agent easily penetrates into the vicinity of the core of the wound hair holding device, and the hair once penetrated into the hair holding device from the outer peripheral portion of the wound hair holding device. The treatment agent is difficult to leak out.

Hereinafter, a preferred embodiment of the hair holding device of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the hair holder 1 of the present embodiment has a sheet 23 </ b> A that allows the hair bundle H (see FIG. 3) to be inserted from the opening 21 at one end toward the opening 22 at the other end. The basis weight of the sheets 23A and 23B constituting the cylindrical body 2 is gradually decreased from the opening 21 at the one end toward the opening 22 at the other end. doing.

  As shown in FIGS. 1 and 2, the cylindrical body 2 is formed by joining two rectangular sheets 23 </ b> A and 23 </ b> B together with side end portions 24 and 24 along the longitudinal direction thereof. The surface shape has a flat shape formed by joining two straight surfaces. In FIG. 1, for convenience, the cylindrical body 2 is illustrated in a state where the opening is opened in a flat shape formed by joining two arcuate surfaces.

As shown in FIG. 2, the one sheet 23A is formed by bonding three sheets of a first base sheet 31A, a second base sheet 32A, and a third base sheet 33A.
As shown in FIG. 2, the first base sheet 31 </ b> A extends from the opening 21 at one end of the cylindrical body 2 to the opening 22 at the other end. The second base sheet 32A extends from the opening 21 at one end of the cylindrical body 2 to approximately 2/3 of the entire length of the cylindrical body 2, and is bonded to the outer peripheral surface of the first base sheet 31A. . The third base sheet 33A extends from the opening 21 at one end of the cylindrical body 2 to approximately 1/3 of the entire length of the cylindrical body 2, and is bonded to the outer peripheral surface of the second base sheet 32A. .
As shown in FIG. 2, the other sheet 23B is formed by bonding three sheets of a first base sheet 31B, a second base sheet 32B, and a third base sheet 33B, similarly to the one sheet 23A.

  In each of these base material sheets, the basis weight of the sheet alone is uniform in the sheet longitudinal direction. Therefore, the basis weight of one sheet 23A is gradually reduced in three stages in the longitudinal direction of the cylindrical body 2, and the cylindrical body 2 as a whole is shown in FIG. The basis weight in the region P3 of about 1/3 of the total length of 2, the basis weight in the region P2 of about 1/3 of the central portion in the longitudinal direction of the entire length of the cylindrical body 2, and the opening from the opening 22 at the other end The ratio with the basis weight in the region P1 that is approximately 1/3 of the total length of 2 is 3: 2: 1.

In one sheet 23A and the other sheet 23B, the basis weight in the vicinity of the opening 21 at one end (in the present embodiment, the region P3) is 50 to 500 g / m ² , preferably 100 to 300 g / m. ² . Also, the basis weight of the openings 22 near the other end (region in this embodiment P1) is 10 to 150 g / m ^2, preferably from 20 to 100 g / m ^2. Moreover, longitudinal central part the basis weight of the (region P2 in this embodiment) is 40~250g / m ^2, preferably from 50 to 250 g / m ^2, more preferably 50 to 200 g / m ² It is. When the basis weight is defined in such a range, it is easy to wind up the cylindrical body in a roll shape, which is preferable.

  The vicinity of the opening 21 at one end (region P3) is highly rigid as a result of the increased basis weight. Therefore, when hair is taken in, even if the hair is caught in the opening 21 at one end, the opening 21 at one end is hardly deformed, and it is easy to take in the hair.

  The cylindrical body 2 has a length L of 20 to 500 mm, preferably 100 to 300 mm. Further, the cylindrical body 2 has a ratio (L / W) of the length L to the width W of 0.7 to 0.2, preferably 0.5 to 0.3. When the ratio (L / W) is 0.7 to 0.2, the insertability of the hair into the cylindrical body is good.

  As the sheet constituting the cylindrical body 2, various flexible materials are used, and examples thereof include nonwoven fabric (polyethylene nonwoven fabric, polyethylene terephthalate nonwoven fabric, etc.), woven fabric, paper, or a composite thereof.

Next, as one usage mode of the hair holding tool of the present embodiment, a case in which curl is directly imparted to the hair (head hair) by a permanent treatment will be described with reference to FIG.
First, depending on the amount of hair bundle H and the curl shape to be obtained, a hair holder 1 comprising a cylindrical body 2 having an appropriate length and width is used, as shown in FIG. The opening 21 at one end of the body 2 is opened in an elliptical shape, and the hair bundle H is inserted through the opening 21. Then, as shown in FIG. 3 (b), the hair bundle H is inserted into the tubular body 2 until the tip of the hair bundle H protrudes slightly from the opening 22 at the other end of the tubular body 2. In that case, it is preferable to use the hair insertion tool (not shown) which is an auxiliary tool which inserts hair in a cylindrical body.

  After the hair bundle H is inserted through the tubular body 2, as shown in FIGS. 3C and 3D, the tubular body 2 is wound with a desired winding diameter from the opening 22 side at the other end. Turn and hold the wound state of the hair bundle H using known fixing means such as a clip (not shown). Thereafter, a permanent hair treatment agent is applied to the hair bundle H from the outside of the cylindrical body 2.

  Here, according to the cylindrical body 2 in the present embodiment, the basis weight is not uniform in the longitudinal direction, and from one opening 21 that is an insertion port of the hair bundle H toward the other opening 21. Therefore, at the time of winding, the basis weight of the cylindrical body 2 in the vicinity of the core is small, and the hair treatment agent easily penetrates to the vicinity of the core. In addition, in the vicinity of one opening 21, since it has a sufficient basis weight, it is difficult for the hair treatment agent that has once penetrated into the cylindrical body 2 from the outer peripheral portion of the wound hair holding tool to leak out.

Then, after a predetermined time, the hair bundle H is inserted into and removed from the tubular body 2 and the hair is washed to complete the permanent treatment. As a result, according to the hair holder 1 of the present embodiment, it is possible to easily and reliably impart beautiful curls to the hair.
In addition, when inserting the hair bundle H from the opening part 21 of the cylindrical body 2, it is easier to insert the hair bundle H smoothly if the opening part 21 is opened in a perfect circle as necessary. Further, it is not always necessary that the tip of the hair bundle H protrudes from the opening 22 at the other end of the cylindrical body 2.

  Next, another embodiment of the hair holder of the present invention will be described. These embodiments will be described only with respect to differences from the embodiments shown in FIG. 1 and FIG.

The hair holding tool 1 according to the embodiment shown in FIG. 4 is crushed by a predetermined means so that the state is maintained in a state of being rolled up. Therefore, when the cylindrical body 2 is stretched in the longitudinal direction and released from the state, the cylindrical body 2 is spontaneously wound up into a roll-up state.
In order to attach to the cylindrical body 2, it is convenient to use an elastically deformable material formed in a predetermined shape as the constituent sheet. Examples of the elastically deformable material include polyethylene terephthalate, polypropylene, polystyrene, polyacrylonitrile and the like.
In order to roll up the cylindrical body 2 using these elastically deformable materials, the cylindrical body 2 is wound up into a roll shape, and the rolled-up form is maintained by a predetermined means. What is necessary is just to heat the cylindrical body 2 to predetermined temperature.

  When the hair holder 1 according to the embodiment shown in FIG. 4 is used, after inserting the hair into the tubular body 2 and releasing the stretched state of the tubular body 2 in the stretched state, the tubular body 2 is It is rolled up spontaneously. Therefore, the hair holder 1 of this embodiment does not require any hoisting operation. In addition, the hair holder of the present embodiment has an advantage that means for holding the winding form such as a clip is unnecessary.
