Description

  The present invention relates to a hair holding tool used as an auxiliary tool when a hair bundle is wound into a predetermined shape when curling hair with a permanent or the like.

  The following Patent Document 1 includes a flat cylindrical body composed of a sheet that allows the hair bundle to be inserted from the opening at one end toward the opening at the other end. , A hair holding device that is crushed so as to maintain a state of being wound up in a predetermined shape. According to this hair holder, by inserting the hair bundle into the stretched tubular body and then releasing the stretching force on the tubular body, the tubular body spontaneously rolls up (hereinafter, Such a voluntary curling force is called “voluntary curling force”), and the hair bundle can be rolled up together with the cylindrical body, and curling can be imparted to the hair by a simple operation.

  When the amount of spontaneous winding force is large, even if the insertion amount of hair increases, it is possible to wind up beautifully, and after the hair is inserted, it is difficult for the hair to slip off. Increasing the thickness of the sheet forming the cylindrical body is effective for obtaining a larger voluntary winding force, but if the sheet thickness is increased, the penetration of the hair treatment agent into the cylindrical body is effective. As a result, the retainability of the hair treatment agent increases and the diameter difference between the winding core side and the outside increases. As a result, the efficiency of hair treatment decreases.

Hereinafter, a preferred embodiment of the hair holding device of the present invention will be described with reference to FIG.
As shown in FIG. 1, the hair holder 1 of the present embodiment is configured by sheets 23 </ b> A and 23 </ b> B so that a hair bundle H (see FIG. 2) can be inserted from the opening 21 at one end toward the opening 22 at the other end. The tubular body 2 is a hair holding tool that is attached to the tubular body 2 so that the state of being rolled up in a predetermined shape is retained. A band-shaped reinforcing member Q made of a material having a glass transition point of room temperature or higher is provided along the longitudinal direction of the cylindrical body 2, and the winding force of the cylindrical body 2 is 0.5 N or more.

The hair holder 1 of this embodiment will be described in detail below.
As shown in FIG. 1, the cylindrical body 2 is formed by joining two rectangular sheets 23 </ b> A and 23 </ b> B with side end portions 24 and 24 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.

The cylindrical body 2 is crushed by a predetermined means so that a state of being rolled up with a sheet (hereinafter also referred to as “one-side sheet”) 23 </ b> A forming one surface being outside is held. . Therefore, when the cylindrical body 2 is stretched in the longitudinal direction and released from that state, the cylindrical body 2 is spontaneously wound up into a roll-up state as shown in FIG. .

As described above, the tubular body 2 is heated to a predetermined temperature under the state where the tubular body 2 is wound up in a roll shape, but the one-side sheet 23A and the other-side sheet 23B are formed. When the ratio of the amorphous part of the material is 50% or more, the temperature at which the squeezing occurs in the cylindrical body 2 becomes low, and the squeezing to the cylindrical body 2 becomes easier.
The “amorphous part” in the present invention means a part in a solid state in which almost no crystallinity is observed in the material, and is a part other than the crystalline part.

The ratio (%) of the “amorphous portion” in the present invention is a value calculated using the degree of crystallinity obtained by the following formula (1). In the formula, Xc: crystallinity, ρc: density of crystalline part, ρa: density of amorphous part, ρ: density of sample (measuring object), ρc and ρa are known depending on the substance, ρ Can be obtained separately from volume and mass. Xc is a value between 1 and 0. When Xc is 1, it means that all of the sample is a crystalline portion, and when Xc is 0, all of the sample is an amorphous portion. It means that there is. Therefore, the ratio of the amorphous part in the present invention is a value obtained by subtracting the value of the crystalline part obtained by the following formula (1) from 1 and multiplying it by 100.
(1 / ρ) = (Xc / ρc) + (1-Xc) / ρa (1)

In order to attach the reinforcing member Q to the reinforcing member Q, the cylindrical body 2 is rolled up, and the winding form is maintained by a predetermined means, and the reinforcing member Q is heated to a predetermined temperature together with the cylindrical body 2 under the state. However, if the proportion of the amorphous portion of the material constituting the reinforcing member Q is 50% or more, the temperature at which the reinforcing member Q appears is reduced, and the reinforcing member Q is more easily attached. It becomes.

In this embodiment, since the cylindrical body 2 has the above-described configuration, the winding force of the cylindrical body 2 is 0.5 N or 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”.

Depending on the amount of the 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. First, the tubular body 2 is stretched, and in this 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.

After the hair bundle H is inserted into the tubular body 2, if the stretched state of the tubular body 2 is released, as shown in FIGS. 2 (a) and 2 (b), the tubular body 2 moves the one-side sheet 23 </ b> A outside. Then, it is wound up spontaneously from the opening 22 side at the other end. And as shown in FIG.2 (c), the mechanical fastener 5 of the extension part 4 is engaged with the single sheet | seat 23A of the cylindrical body 2, and the winding state of the hair bundle H is hold | maintained.
Thereafter, a permanent hair treatment agent is applied to the hair bundle H from the outside of the cylindrical body 2.

Further, the tip of the hair bundle H may protrude from the opening 22 at the other end of the cylindrical body 2.

According to the hair holder 1 of this embodiment, since the strip | belt-shaped reinforcement member Q which consists of a raw material which has a glass transition point more than room temperature is provided along the longitudinal direction of the cylindrical body 2, the cylindrical body 2 is used. Even if a thick sheet is not used for the sheets 23A and 23B to be formed, a sufficiently large spontaneous winding force can be obtained. Therefore, a sufficiently large voluntary winding force can be obtained without reducing the efficiency of the hair treatment.
In addition, since the sheet 23A that forms one surface of the cylindrical body 2 and the sheet 23B that forms the other surface are also made of a material having a glass transition point of room temperature or higher, the spontaneous winding force is further increased. .
