Definitions

  • the present invention relates to a perming rod utilized for permanent wave treatment at a hair salon etc.
  • a perming rod for winding hairs has been utilized.
  • a permanent hair rod disclosed in Patent Literature 1 has been known as a typical perming rod.
  • the permanent hair rod disclosed in Patent Literature 1 is made of synthetic resin in a cylindrical shape forming a drum shape in which the diameter of a center portion in an axial direction is slightly smaller.
  • cutout portions for retaining a rubber band are provided next to each other at required intervals in a circumferential direction. Hairs wound around the permanent hair rod are fixed by the rubber band hooked on the cutout portions.
  • Patent Literature 2 discloses, as another typical technique example, a permanent rod including a rod portion.
  • the rod portion has an elastic hollow body.
  • the elastic hollow body has a skin layer on a surface, and is made of low-foaming hollow synthetic rubber, thermoplastic elastomer, or soft synthetic resin.
  • the rod portion of this literature has a hollow or solid core member inserted and fixed into a hollow of the elastic hollow body.
  • the core member is made of synthetic resin or a wood.
  • the permanent rod of this literature includes a cap.
  • the cap is fixed to a joint portion arranged at an end portion of the core member of the rod portion.
  • a tubular body forming a cap body has, at one end thereof, an external fitting portion fitted onto an end portion of the rod portion.
  • a rubber retaining portion cut in a recessed-raised shape is formed.
  • Document US 6 283 128 B1 discloses a perming rod in accordance with the preamble of claim 1.
  • the perming rod of the typical technique needs to be improved for enhancing the efficiency of treatment by a beautician and obtaining beautiful permanent waves.
  • the synthetic resin perming rod formed in the cylindrical shape as in the typical technique disclosed in Patent Literature 1 has the hard outer peripheral surface, and the force of such a perming rod for holding the hairs is small. Thus, the hairs easily slip. Further, the perming rod is formed in a hollow shape, and therefore, there is a problem that heat transfer is poor and beautiful wave curl cannot be obtained within short time.
  • the outer peripheral surface is slightly elastically deformable in a radial direction.
  • the amount of such deformation is insufficient, and it is difficult to reduce displacement of the hairs while reducing the pain felt by the customer.
  • the perming rod is too soft, it is difficult to form wave curl of the hairs in a suitable shape.
  • the perming rod formed, at both ends thereof, with the cutout portions (the rubber retaining portions) for hooking the rubber band as in the typical techniques disclosed in Patent Literature 1 and Patent Literature 2 has a problem that it is difficult to perform the process of hooking the rubber band on the cutout portions.
  • the position of the cutout portion is fixed with respect to the outer peripheral surface on which the hairs are wound, and the cutout portion cannot be moved in a rotation direction of the perming rod.
  • the hairs wound around the perming rod are, by the rubber band hooked on the cutout portions, strongly fixed not to move in the circumferential direction.
  • the hairs are kept pulled strongly from the head, and for this reason, the customer might feel pain.
  • the present invention has been made in view of the above-described situation, and an object of the present invention is to provide a perming rod allowing beautiful permanent waves by easy treatment.
  • a perming rod having an outer peripheral surface around which hair is to be wound, includes a columnar core, an elastic portion covering an outer peripheral surface of the core and formed of an elastic body, a waterproof surface portion covering an outer peripheral surface of the elastic portion, and a pin attached to each end portion of the elastic portion.
  • a perming rod of the present invention includes a columnar core, an elastic portion covering an outer peripheral surface of the core and formed of an elastic body, a waterproof surface portion covering an outer peripheral surface of the elastic portion, and a pin attached to each end portion of the elastic portion.
  • the columnar core is provided at a center portion of the perming rod so that strength of the entirety of the perming rod can be suitably ensured.
  • the elastic portion and the surface portion are provided at the outer periphery of the core.
  • the entirety of the perming rod is formed in a substantially columnar shape without forming a hollow in the vicinity of the center portion of the perming rod.
  • heat transfer performance suitable for treatment for obtaining beautiful wave curl is obtained.
  • the elastic portion formed of the elastic body is provided at the outer periphery of the core so that hairs wound around the perming rod can be supported without suitable tension by deformation of the elastic portion.
  • the waterproof surface portion is formed at the outer periphery of the elastic portion so that the flow of a chemical solution into the perming rod can be prevented and treatment efficiency can be enhanced. Moreover, the surface portion is provided so that slippage of a wound hair bundle can be reduced. With excellent deformability of the elastic portion and suitable friction performance of the surface portion, the hair bundle can be firmly held even in a case where a rubber band is loosely hooked on the surface portion. Thus, beautiful permanent waves can be obtained without less damage.
  • the pin on which the rubber band is to be hooked is attached to each end portion of the elastic portion.
  • the pin and the rubber band hooked on the pin can move together with the end portion of the elastic portion according to deformation of the elastic portion.
  • the hairs can be supported with such tension that permanent waves can be easily obtained and suitable motion is allowed.
  • the elastic portion may be elastically deformable in a radial direction and a circumferential direction.
  • the hairs can be wound.
  • the hairs wound around the perming rod are held with suitable holding force obtained by repulsion of the elastic portion.
  • loosing of the hairs can be prevented without providing strong tension leading to pain of the scalp, and beautiful permanent waves can be obtained.
  • the surface portion may be formed continuously from an outer peripheral surface of the elastic body to cover end portions of the core and the elastic portion.
  • the pin may be formed in a U-shape in such a manner that a rod-shaped body is bent, and both end portions of the pin may be inserted into the elastic portion.
  • the process of hooking the rubber band can be easily performed.
  • the rubber band can be fixed through a hole of the pin formed by insertion of the substantially-U-shaped rod-shaped body into the elastic portion.
  • the surface portion may be made of a rubber material.
  • an electronic circuit configured to output information on the perming rod may be embedded in the elastic portion. Utilizing the information on the perming rod from the electronic circuit, a practitioner can accurately perform, with high efficiency, treatment suitable for each customer.
