The hair is dyed by applying a hair dye.

JP 2000-253922 A

  However, in the hair winding device disclosed in Patent Document 1, not only the hair bundle held when closing the mouth of the hair fastener, but also the surrounding hair is often caught and held, In addition to being bent or hanging, it gives pain to the user and has problems such as poor operability. The above problem is particularly noticeable when processing is performed by oneself, and the operability is remarkably deteriorated.

  Accordingly, an object of the present invention is to provide a hair holding jig and a hair holding tool for hair treatment, which can eliminate the drawbacks of the prior art described above.

  The present invention is a hair holding body opening and closing jig for opening and closing the opening in a cylindrical hair holding body for inserting and holding a hair bundle from the opening at one end toward the other end. Opening and closing treatment for a hair holding body having an insertion port that forms an area where the inner periphery is closed and to which the one end of the holding body is inserted and fixed, and expansion / contraction means for expanding and contracting the insertion port. By providing a tool, the above object is achieved.

  Moreover, this invention provides the hair holding tool for hair treatment by which the opening / closing jig for hair holding bodies of this invention is being fixed to the said one end part of the said hair holding body.

  According to the opening / closing jig for hair holding body and hair holding tool of the present invention, the hair around the hair is hardly caught up and bitten, so that the hair bends or hangs and gives pain to the user. In addition, it is easy to operate.

  Hereinafter, the hair holding device for hair treatment of the present invention (hereinafter also simply referred to as a hair holding device) will be described based on its preferred embodiments with reference to the drawings.

Drawing 1 is a mimetic diagram showing a 1st embodiment of a hair holder of the present invention.
As shown in FIG. 1, the hair holder 1 of this embodiment includes a cylindrical hair holder 2 that holds a hair bundle by inserting a hair bundle from an opening at one end toward the other end, and a hair holder 2. And an opening / closing jig for a hair holding body (hereinafter also simply referred to as an opening / closing jig) 3 for opening and closing the opening at one end of the head. The hair holder 1 is fixed to the inner periphery of the insertion opening 31 by inserting the one end of the hair holding body 2 into the insertion opening 31 of the opening / closing jig 3 described later. Although there is no particular limitation on the fixing method, in consideration of repeated use of the opening / closing jig 3, it is preferable to fix with an adhesive tape or the like in which an adhesive is disposed on both inner surfaces of the insertion opening. The hair holding body 2 may fix the entire circumference of the one end portion or may be partially fixed according to the form of the insertion port 31.

  The hair holding body 2 is mainly composed of a cylindrical body 20. The hair carrier 2 has a hair bundle insertion port 21 and a hair dye injection port 22. In the present embodiment, the opening at one end is the insertion port 21, and the opening at the other end is the hair dye inlet 22. The cylindrical body 20 is formed by joining both side portions 24 and 24 of a pair of strip-shaped sheets 23 and 23.

  The length of the cylindrical body 20 is set to an appropriate length according to the length of the hair to be treated, and is preferably set longer than the length of the hair to be treated. Moreover, the opening part of the cylindrical body 20 is oval shape or circular shape, and the magnitude | size is set to a suitable magnitude | size according to the quantity of the hair bundle to insert. The length L20 of the cylindrical body 20 is 50 to 600 mm, and the sizes of the openings (insertion port 21 and injection port 22) are in the range of a major axis of 5 to 100 mm and a minor axis of 2 to 40 mm. When the major axis and the minor axis are equal, the opening of the cylindrical body 20 is circular.

  The sheet 23 is formed of a material that is impermeable to the hair dye, and the hair dye does not leak out from the peripheral surface of the tubular body 20. As a result, hair other than the hair bundle inserted into the hair carrier 2 is prevented from being dyed. Therefore, the hair dyeing process using the hair carrier 2 of the present embodiment is particularly effective for partial hair dyeing of head hair. In addition, since the hair dye is present in a relatively airtight state in the hair holding body 2, when the hair dye contains a volatile component, the volatile component volatilizes in the hair dye. There is also an advantage that the hair dyeing treatment can be performed efficiently, and the adverse effect that the volatile component is seen in the eyes can be prevented.

  As the material for forming the sheet 23 described above, a film made of a synthetic resin such as a polyolefin such as polyethylene or polypropylene, a polyester such as polyethylene terephthalate, nylon, polystyrene, or vinyl chloride, or a blend of the synthetic resin was used. A film or a synthetic resin film obtained by laminating the film in multiple layers is preferably used.

  As shown in FIG. 2, the opening / closing jig 3 includes an insertion port 31 that forms a region where the inner periphery is closed, and the insertion port 31 to which the one end of the hair holding body 2 is inserted and fixed. Expansion / contraction means 32 for expanding / contracting.

  The opening / closing jig 3 according to the present embodiment includes a hinge member 30 having a long piece portion 34 and a short piece portion 35 which are provided so as to be bent via a thin hinge portion 33. The hinge member 30 is made of a synthetic resin integral molded body (one component). Preferred materials for the hinge member 30 include synthetic resins such as polyethylene resin, polypropylene resin, nylon resin, and polybutylene terephthalate resin.

  In the long piece portion 34, a rectangular guide hole 341 is formed in the vicinity of the tip portion in plan view. Further, the long piece portion 34 is formed with a long hole 342 extending in the longitudinal direction adjacent to the guide hole 341. When the long piece portion 34 extends straight as will be described later, a short piece portion described later is formed. The 35 convex portions 352 are accommodated so that friction between the hair holder and the hair is increased, and the hair holder can be prevented from shifting or falling off from the hair bundle.

  A locking portion 351 that is bent in the closing direction of the hinge portion 33 is formed at the distal end portion of the short piece portion 35. The locking portion 351 is inserted into the guide hole 341 of the long piece portion 34 and locked to the guide hole 341. The short piece portion 35 is formed with a convex portion 352 that fits into the long hole 342 when the long piece portion 34 extends straight.

  The opening / closing jig 3 forms the insertion port 31 by folding back the hinge member 30 at the hinge portion 33 and inserting the locking portion 351 into the guide hole 341 to be locked. The inner periphery of the insertion port 31 is composed of inner surfaces of a long piece portion 34, a short piece portion 35, and a hinge portion 33. Therefore, unlike the structure in which one end is opened and closed like the hair winder described in Patent Document 1, as shown in FIG. 3, the inner periphery of the insertion port 31 forms a closed region.

  As shown in FIG. 3, the expansion / contraction means 32 of the opening / closing jig 3 applies a pressing force so as to crush the long piece portion 34 toward the hinge portion 33 side, or releases the pressing force, thereby reducing the long piece portion 34. The insertion slot 31 is provided so as to be expanded and contracted by being elastically deformed.

  When the hair holder 1 of this embodiment inserts a hair bundle, as shown in FIG. 3, the long piece part 34 is elastically deformed and the insertion port 31 is expanded. Along with this, the hair insertion port 21 of the hair holder 2 is also expanded, so that the hair bundle can be easily inserted. In this state, after inserting the hair bundle from the insertion opening 21 and inserting it to the hairline, as shown in FIG. 2, when the elastic deformation of the long piece 34 is released, the insertion opening 31 narrows and the hair bundle holds the hair. Retained by the tool. And a hair treatment agent is inject | poured in the hair holding body 2, the hair holding body 2 is squeezed, this hair treatment agent is spread, and a desired hair bundle is processed.

  As described above, the expansion / contraction means 32 elastically deforms the long piece 34 or releases the elastic deformation to expand / contract the insertion port 31 (open / close the insertion port 21). Here, in this embodiment, “expansion” of “expansion / contraction” indicates a state in which the long piece portion 34 is elastically deformed (FIG. 3), and “contraction” of “expansion / contraction” indicates elastic deformation of the long piece portion 34. This indicates the state when (1) is solved.

  Thus, since the hair holder 1 of this embodiment is in the state where the insertion port 31 of the opening / closing jig 3 is closed when inserting the hair bundle into the insertion port 21, the surrounding hair is hardly involved. Since it does not bite, it is possible to prevent the hair from being bent or hung and giving pain to the user, and the insertion port 31 can be expanded and contracted (the opening and closing of the insertion port 21). Since it can be easily performed by deformation, it is excellent in operability.
