Hereinafter, the hair holding device of the present invention will be described with reference to FIG. 1 for a first embodiment which is a preferred embodiment thereof.
As shown in FIG. 1, the hair holder 1 of the first embodiment has sheets 23 and 24 that can be inserted through the hair bundle H (see FIG. 4) from the opening 21 at one end toward the opening 22 at the other end. The hair-holding device is composed of a flat-shaped tubular body 2 formed by bonding, and the tubular body 2 is a hair holding tool that is clinched so as to develop a winding force that maintains a wound-up state of a predetermined shape. The cylindrical body 2 is formed by bonding the sheet 23 forming one surface thereof to the sheet 24 forming the other surface in a state where the sheet 23 extends within an elastic deformation range. The hoisting force of the body 2 is developed.

The hair holder 1 of 1st Embodiment is explained in full detail below.
As shown in FIG. 1, the cylindrical body 2 is a flat shape configured by bonding sheets 23 and 24 so that a hair bundle can be inserted from the opening 21 at one end toward the opening 22 at the other end. Two rectangular sheets 23 and 24 are formed by joining side end portions along the longitudinal direction thereof. The size of the cylindrical body 2 is preferably 50 to 350 mm in length, 20 to 100 mm in major axis, and 0 to 30 mm in minor axis, and is appropriately selected according to the length of the hair, the place where the hair is desired to be crushed, and the amount of hair bundle to be inserted. You can choose.

As shown in FIG. 1, the cylindrical body 2 has a sheet (hereinafter also referred to as “one-side sheet”) 23 that forms one surface, and a winding force that holds the rolled-up state in a roll shape is developed. Has been attached. Therefore, when the tubular body 2 is stretched in the longitudinal direction and released from the state, the tubular body 2 is voluntarily wound up into a roll-up state.
In the first embodiment, the tubular body 2 is formed by bonding the single-sided sheet 23 to the other-sided sheet 24 in a state where the single-sided sheet 23 is stretched within the elastic deformation range, so that the winding force of the cylindrical body 2 is expressed. It is made to do.

The manufacturing procedure of the cylindrical body 2 that is attached so as to develop the winding force is as follows.
First, as shown in FIG. 2A, the one-sided sheet 23 is extended within the elastic deformation range. The single-sided sheet 23 can be extended within the elastic deformation range, but the extension length is a main parameter that determines the magnitude of the winding force of the tubular body 2. Next, in a state where the stretched state of the single-sided sheet 23 is maintained, both side ends of the single-sided sheet 23 and both side ends of the other-sided sheet 24 are joined as shown in FIG. For this joining, for example, heat sealing is used. The joining position, joining area, and the like of the one-sided sheet 23 and the other-sided sheet 24 are set according to the sizes of the one-sided sheet 23 and the other-sided sheet 24.
In the cylindrical body 2 manufactured in this way, when the extension force to the one-sided sheet 23 is released, a contracting force is generated in the one-sided sheet 23. Therefore, the cylindrical body 2 is wound from the extended state shown in FIG. 1 (a), as shown in FIGS. 1 (b) and 1 (c). Is expressed.

As described above, the main parameter for determining the winding force of the cylindrical body 2 is the extension length of the single-sided sheet 23 when the single-sided sheet 23 and the other-sided sheet 24 are bonded together. The thickness, material, etc., the thickness, material, etc. of the other side sheet 24 or the joining means, joining position, joining area, etc. of the one side sheet 23 and the other side sheet 24 are also parameters.
The Young's modulus of the single-sided sheet 23 is preferably 500 MPa to 3000 MPa. The thickness of the single-sided sheet 23 is preferably 10 μm to 500 μm. The thickness of the other sheet 24 is preferably 50 μm to 500 μm.
As the one-sided sheet 23 and the other-sided sheet 24 constituting the cylindrical body 2, for example, a polyolefin-based nonwoven fabric, a polyester-based nonwoven fabric, a nylon-based nonwoven fabric, an elastomer-based nonwoven fabric such as polyurethane, and a woven fabric can be used. In this embodiment, a polyethylene non-woven fabric that is permeable to the hair treatment agent is used.
As a means for joining the one-sided sheet 23 and the other-sided sheet 24, for example, adhesion or stitching can be used in addition to heat sealing.

In this embodiment, since the cylindrical body 2 has the above-described configuration, a winding force that maintains the winding state in which the one-sided sheet 23 is on the inside is expressed. The winding force of the cylindrical body 2 is preferably 0.5 N or more, more preferably 0.8 N or more.
The “winding force of the cylindrical body” in the present invention is a winding force measured as follows.
As shown in FIG. 3, the cylindrical body 2 in which the winding shape is stored in advance is set on the outer periphery of the roller R. The roller R is preferably provided with a bearing mechanism in order to minimize the frictional force. Thereafter, the end value of the cylindrical body 2 is chucked with the clip C or the like, and the maximum value when the cylindrical body 2 is pulled out in the horizontal direction using the force gauge G is defined as “winding force”.

Next, one usage mode of the hair holder of the first embodiment shown in FIG. 1 will be described with reference to FIG.
Depending on the amount of the hair bundle H and the curl shape to be obtained, the hair holder 1 composed of the cylindrical body 2 having an appropriate length, width, winding force, winding shape and the like is used. First, as shown in FIG. 4A, the tubular body 2 is stretched, and in that state, the opening 21 at one end of the tubular body 2 is opened in an elliptical shape, and the hair bundle H is inserted through the opening 21. To do. In that case, if the hair insertion tool (not shown) which inserts or penetrates the hair bundle H into the hair holder 1 is used, the operation of inserting the hair bundle H becomes simple.

Then, as shown in FIG. 4 (b), after the hair bundle H is inserted through the tubular body 2, the stretched state of the tubular body 2 is released, as shown in FIGS. 4 (c) and (d). Moreover, the cylindrical body 2 rolls up spontaneously from the side of the opening 22 at the other end with the single-sided sheet 23 as the inside.
Thereafter, a permanent hair treatment agent is applied to the hair bundle H from the outside of the cylindrical body 2. The hair treatment agent is applied to the hair bundle H via the one side sheet 23 and the other side sheet 24. After a predetermined time, the hair bundle H is inserted and removed from the tubular body 2, and the perm treatment is completed by washing the hair.
When inserting the hair bundle H from the opening 21 of the cylindrical body 2, it is easier to smoothly insert the hair bundle H if the opening 21 is opened in a perfect circle if necessary. Further, the tip of the hair bundle H may protrude from the opening 22 at the other end of the cylindrical body 2.

In the hair holder 1 of the first embodiment, the tubular body 2 is formed by bonding the other sheet 24 in a state where the one-face sheet 23 is stretched within the elastic deformation range. Since the hoisting force is developed, the hoisting state is maintained without using the means for holding the hoisting state of the cylindrical body 2 and the means for heating the hoisting cylindrical body 2. A hair holding tool having the cylindrical body 2 can be easily manufactured.
Moreover, since the sheet prescribed | regulated to the predetermined Young's modulus, thickness, and material is used as the sheet | seat 23, it can manufacture easily and can provide the voluntary winding force required in order to wind up a hair | bristle bundle. Is possible.

It is mainly different in that it is made of a sheet and the winding force of the cylindrical body 2 is expressed by the winding force of the multilayer sheet. About another point, it is the same as that of the hair holder 1 of 1st Embodiment.

  In the hair holder 1 of 2nd Embodiment, as shown in FIG. 5, the single-sided sheet 23 consists of a multilayer sheet | seat made | formed so that winding-up force might be expressed. More specifically, the multilayer sheet is a two-layer sheet, and the laminated sheet is formed by bonding the first layer material 23A to the second layer material 23B in a state of being stretched within the elastic deformation range. Thus, the winding force of the laminated sheet is developed.

The manufacturing procedure of the single-sided sheet 23 that is adapted to develop the winding force is as follows.
First, as shown in FIG. 5A, the first layer material 23A is stretched within an elastic deformation range. The material 23A of the first layer can be stretched within the elastic deformation range, but this stretch length is a main parameter that determines the magnitude of the winding force of the single-sided sheet 23. Next, with the first layer material 23A held in an expanded state, the first layer material 23A and the second layer material 23B are bonded to the entire surface through the adhesive layer 23C as shown in FIG. 5B. Join them together.

As the material 23A of the first layer, for example, a polyethylene film or an ethylene vinyl acetate (EVA) film can be used. In this embodiment, a polyethylene film is used. As the material 23B of the second layer, for example, a polyethylene terephthalate film, a polypropylene film, a polyethylene film, a polyacryl film, or a polystyrene film can be used.

As a joining means between the first layer material 23A and the second layer material 23B, for example, stitching can be used in addition to adhesion. The first layer material 23 </ b> A and the second layer material 23 </ b> B do not necessarily have to be joined together, and may be joined together.

In the single-sided sheet 23 manufactured as described above, when the extension force to the first layer material 23A is released, a contraction force is generated in the first layer material 23A. Therefore, the single-sided sheet 23 develops a winding force that maintains a roll-shaped winding state with the first layer material 23A inside as shown in FIG. 5 (c) from the stretched state shown in FIG. 5 (b). To do.
And the both-sides edge part of the single-sided sheet 23 and the both-sides edge part of the other surface sheet (not shown) manufactured separately are joined.

The other side sheet can be bonded to either the first layer material 23A side or the second layer material 23B side of the one side sheet 23.
In a cylindrical body (not shown) in which the other side sheet is joined to the second layer material 23B side in the one side sheet 23, a winding force that maintains the roll-like winding state with the one side sheet 23 inside is developed. . Moreover, in the cylindrical body (not shown) of the form which joined the other sheet | seat to the material 23A side of the 1st layer in the sheet | seat 23, the sheet | seat 23A on the other side was made inside (in other words, material 23A of the 1st layer The winding force that holds the rolled-up state (inside) is developed.

In the tubular body in which the other side sheet is joined to the second layer material 23B side of the one side sheet 23, the second layer material 23B and the other side sheet are joined first, and then the second layer material. A cylindrical body can also be manufactured by joining 23B and the first layer material 23A.

And the second layer material 23B are bonded together in a molten state and then solidified, and the contraction rate when the first layer material 23A shifts from the molten state to the solidified state is the second layer material. The main difference is that the roll-up force of the laminated sheet is expressed because it is larger than the contraction rate when the molten state in 23B shifts to the solidified state. About another point, it is the same as that of the hair holder 1 of 2nd Embodiment.

The one side sheet | seat 23 in the hair holder of 3rd Embodiment is explained in full detail.
As shown in FIG. 6, the one-sided sheet 23 is a laminated sheet, and is formed by bonding the first layer material 23 </ b> A and the second layer material 23 </ b> B in a molten state and then solidifying them. Further, the shrinkage rate when the first layer material 23A shifts from the molten state to the solidified state is larger than the shrinkage rate when the second layer material 23B shifts from the molten state to the solidified state. The roll-up force of the laminated sheet is expressed.

  As the material 23A of the first layer, for example, ethylene vinyl acetate copolymer resin or polyethylene resin can be used. In this embodiment, an ethylene vinyl acetate copolymer resin is used. As the material 23B of the second layer, for example, polyethylene terephthalate resin, polyacrylic resin, polystyrene resin, polyethylene resin, or polypropylene resin can be used. In this embodiment, polyethylene terephthalate resin is used.

The manufacturing procedure of the single-sided sheet 23 that is adapted to develop the winding force is as follows.
First, as shown in FIG. 6A, the first layer material 23A and the second layer material 23B are coextruded with an adhesive layer 23C interposed therebetween. Thereafter, the material 23A of the first layer and the material 23B of the second layer are naturally cooled or forcedly cooled. As a result, a one-sided sheet 23 in which the first layer material 23A and the second layer material 23B are entirely bonded via the adhesive layer 23C is obtained.

  In the single-sided sheet 23 manufactured in this way, the first layer material 23A has a higher shrinkage rate when it is shifted from the molten state to the solidified state than the second layer material 23B. The material 23A is more contracted than the second layer material 23B. Therefore, the single-sided sheet 23 develops a winding force that maintains a roll-shaped winding state with the first layer material 23A inside as shown in FIG. 6 (b) from the stretched state shown in FIG. 6 (a). To do.

And the both-sides edge part of the single-sided sheet 23 and the both-sides edge part of the other surface sheet (not shown) manufactured separately are joined.
The other surface sheet can be bonded to either the first layer material 23A side or the second layer material 23B side of the one surface sheet 23, similarly to the cylindrical body in the second embodiment shown in FIG.
