Definitions

  • the present invention relates to a perming rod used in perming.
  • a prior art perming rod designated generally by numeral 51 is cylindrically shaped and has its outer periphery 51a formed with a plurality of apertures 60 for discharging an excessive perming treatment solution to prevent it from being left on the hair.
  • the axial grooves serve not only to discharge an excessive perming solution but also to engage the hair at their edges.
  • each hair makes point-to-point contact with the outer periphery of the rod along the edges of the axial grooves, producing a large friction therebetween.
  • the hair can thus be pulled with a large tension so as to be formed with fold lines along the edges of the axial grooves.
  • Figs. 1 and 2 show the first embodiment of the present invention in which a perming rod 1 has a body 2 made of a solid wooden material and has a substantially elliptical cross-section. Four axial grooves 5A to 5D are formed in its outer periphery.
  • the rod body may be made of other materials than wood such as synthetic resin.
  • the rod should have such a length that a bundle of hair H can be rolled therearound to its root. If the user has short hair, each bundle of the hair may be wound around the rod so as to be stacked one upon another on a limited area of the periphery of the rod. Conveniently, a plurality of rods of various lengths may be prepared so as to cope with various lengths of hair.
  • the outer periphery 2a of the rod is partitioned into four arcuate surfaces by the grooves 5A to 5D.
  • the rod body 2 is formed in its elliptical end faces 2b with grooves 9 diametrically extending along their minor axes.
  • a rubber band (not shown) is adapted to be put on the rod from one end to the other so as to be engaged in the grooves 9, thus holding the bundle of hair H in position on the outer periphery 2a of the rod body.
  • the grooves 9 may be formed along the major axes of the elliptical end faces or may be in the shape of a cross.
  • the axial grooves 5A to 5D have suitable depth and are arranged so that the respective two of them will be in a symmetrical relationship with respect to the plane including the major axes of the elliptical end faces. They serve to discharge an excessive perming treatment solution, thus preventing it from being left on the hair.
  • the axial grooves 5A to 5D have their respective pairs of edges 5a, 5b, 5c and 5d sharply cornered with each pair of edges spaced from each other by a distance W.
  • hair portion Ha on the top of the periphery 2a will be engaged by the adjacent ones of the edges 5a and 5b of the grooves 5A and 5B
  • hair portion Hb on the lefthand side of the periphery 2a will be engaged by the adjacent ones of the edges 5b and 5c
  • hair portion Hc on the bottom of the periphery will be engaged by the adjacent ones of the edges 5c and 5d
  • hair portion Hd will be engaged by the adjacent ones of the edges 5d and 5a. Since the hair wound around the rod is thus strongly held on the periphery 2a of the rod with a large frictional force, the tension to the hair can be increased. This will allow the bundle of hair to be permed in a short time into a shape substantially in conformity with the elliptical shape of the periphery 2a of the rod body 2.
  • a first perming treatment solution (which is alkaline and serves to cut off the cystine bonds in each hair to cause it to swell) is applied all over the hair. Then, as shown in Fig. 1, a bundle of hair H of a desired number are wound around the rod 1. The rod is then turned with fingers to roll up the bundle of hair H to their root while pulling them with a suitable tension. They have to be rolled helically so as not to overlap one turn upon another.
  • a rubber band (not shown) is put on the rod 1 from one end to the other so as to engage in the grooves 9 to hold the hair in position.
  • a plurality of such rods are used to roll up all the hair.
  • the hair is left as it is until the first treatment solution acts on it.
  • a second perming treatment solution is applied through the hair.
  • the second solution is acidic and serves to neutralize the hair to reunite the cystine bonds. After the second solution has been allowed to act on the hair, the rods are removed from the hair.
  • the perming rod according to the present invention With the perming rod according to the present invention, a large tensile force can be applied to the hair H on the points P along the edges 5a, 5b, 5c and 5d of the axial grooves 5A, 5B, 5C and 5D, respectively.
  • the hair will be permed in a short period of time even if rather weak perming solutions (first and second solutions) are used, so that the wave of the hair will last long.
  • Fig. 3 shows the perming rod 11 of the second embodiment formed in its outer periphery with three axial grooves 15A, 15B and 15C so that the rod 11 will have a substantially regular triangular section.
  • Each of the grooves 15A, 15B and 15C have its respective pair of edges 15a, 15b and 15c kept at a rather large distance from each other so that hair will be permed with a small radius of curvature and the adjacent waves will be a larger distance away from each other.
  • Fig. 4 shows the perming rod 21 of the third embodiment formed in its outer periphery with four axial grooves 25A to 25D having pairs of edges 25a to 25d, respectively. The distances between the respective pairs of edges are equal to one another so that the rod will have a substantially square section. With this rod, a bundle of hairs can be permed into a substantially square shape.
  • Fig. 5 shows the perming rod 31 of the fourth embodiment formed in its outer periphery with five axial grooves 35A to 35E so that the rod will be given a substantially regular pentagonal section.
  • the distances between respective pairs of edges 35a to 35e of the axial grooves 35A to 35E are equal to each other and smaller than the distances between the pairs of edges in the second embodiment shown in Fig. 4 so that the hairs wound around the rod 31 will be permed with a larger radius of curvature.
  • Fig. 6 shows the perming rod 41 of the fifth embodiment having a substantially rectangular cross-section and formed in its four sides with axial grooves 45A to 45D.
  • the distances between respective pairs of edges 45a, 45c and those between respective pairs of edges 45b and 45d are different from each other, thus allowing the hair to be permed in a variety of ways.
  • the rods have solid cores but may have their cores hollow as shown in Fig. 7 by way of example. Further, the perming rods throughout the preferred embodiments may have both ends thereof somewhat bulged as shown in Fig. 8 by way of example so as to prevent a rubber band put on the rods from pressing too tight against the hair wound around the rod.
