Abstract

PROBLEM TO BE SOLVED: To provide a perm rod that can create various hair styles by adding change to the rich (sense of curling, texture) at the time when applying wave on a hair.SOLUTION: Perm rods 1, 2 are formed of recesses 12, 22 with rubber bands bridged at both ends of a square pole 11 or a triangle pole 21 in the longitudinal direction. A cross-sectional corner of a rectangular column exhibits an acute angle shape not forming a curved surface with an adjacent side face space and does not generate roundness in the corner. Thereby, a stress from a corner becomes strong when winding a hair around the rectangular column, and a hair style having different rich is achieved in comparison with the time when using a conventional round rod. Especially, a triangle and a quadrangle have the stress from the corner stronger than a cross section approaching a circle such as a pentagon and a hexagon, and the wave with three-dimensional impression where the corner is emphasized locally can be formed.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a permanent rod for wrapping hair when waving hair and a method of using the same.

  There are various types of permanent rods that are used when waves are applied to hair, and rods that have been widely used conventionally have cylindrical shapes (FIG. 7). The rod shown in FIG. 7 has protrusions formed as rubber band stops at both ends, and after the hair is wound around the rod, the rubber bands are passed over the protrusions at both ends of the rod to fix the rod and the hair.

  In addition to the cylindrical shape, there are rods having a prismatic shape. Patent Document 1 discloses a quadrangular shape, and Patent Document 2 discloses a hexagonal shape to an octagonal shape, both of which have rounded corners. It is what has.

JP 2011-183010 A (Claim 1, paragraph [0013]) Japanese Utility Model Publication No. 57-202801 (Claim 4)

  Thus, the conventional rod has a roundness in the longitudinal direction, and prevents the corners from damaging the hair when the hair is wound around the rod. Further, in order to prevent the damage from becoming large, there is no triangle with a small acute angle, and most of the polygons having a large number of corners are rounded so as to be closer to a circle.

  On the other hand, there are many people who want a permanent wave that is rich in variation and rich in variety, so that various hairstyles can be provided by applying waves to the hair using a rod with a new shape that has never existed before. Become.

  The present invention has been made in view of these points, and its purpose is to change the richness (curl feeling, texture) of the hair when it is waved, and to achieve various hairstyles. It is to provide a rod for use.

  In order to solve the above problems, the present invention provides the following.

  (1) A permanent rod comprising a rod-like prismatic body and concave portions formed at both ends in the longitudinal direction of the prismatic body, wherein the corner of the transverse section of the prismatic body has a curved surface between adjacent side surfaces. A permanent rod, which has a square shape that does not form.

  According to the present invention, the corners of the cross section of the prismatic body have a square shape (acute angle, right angle) that does not form a curved surface between adjacent side surfaces, and the corners are not rounded. When the hair is wound around the hair, the stress applied to the hair becomes stronger, and it is possible to realize a hair style that is richer than when using a rounded rod.

  In addition, the corners between adjacent side surfaces are excellent in that the perms are less likely to sag because the stronger stress applied to the hair can cope with the hair quality that is less susceptible to perm.

  (2) The prismatic body is a rectangular flat plate plate composed of a wide surface and a narrow surface, the wide surface is a smooth strip, and the concave portions are formed at both ends in the longitudinal direction, and the width Permanent rod characterized in that the narrow surface is an uneven strip.

  According to the present invention, the wide surface is a smooth line, and the narrow surface is an uneven line, so that the hair is applied to the wide surface, and since it is smooth, the hair is not caught and the position of the hair is adjusted. It is suitable, and by winding the hair using the narrow surface, the hair is caught by the uneven stripes and becomes easy to fix.

  (3) The rod for permanents, wherein the side surface of the prismatic body is curved in a concave shape from both longitudinal ends to the center.

  According to the present invention, the perimeter from the both ends to the center of the prismatic body is different, and the stress applied to the hair when the hair is wound around the prismatic body is partially different. It is possible to achieve hairstyles that are not finished but have different richness. In addition, it is possible to provide use according to the hair quality, such as winding the hair root around both ends and winding the hair tip near the center. In addition, the direction which is curving concavely rather than curving convexly is suitable because the stress applied to the hair from the corner is large.

  (4) The perm rod is formed of a material that can be discolored by application of a permanent liquid and / or a change in surface temperature.

  According to the present invention, since it is a prismatic body that can be discolored by application / penetration of the permanent liquid, it is possible to prevent forgetting to attach the permanent liquid due to the discoloring action, or to be a measure of the standing time after the permanent liquid is applied. Can do. Moreover, since it is a prismatic body that can be discolored by changes in surface temperature, it can contribute to optimization of the permeation temperature and the drying temperature in the permanent.

  In addition, by closely monitoring the permeation of the perm solution and the change in the surface temperature, it is possible to control the time and temperature after the perm solution has been applied, so that the damage to the hair can be suppressed. Can do.

  In addition, when the hair is heated with a hair dryer or infrared heater after perm setting, it is possible to visually confirm that the surface temperature of the perm rod is adequate, and that reversible changes are possible. Thus, the original color is restored, so that it is possible to visually recognize a guideline for cooling after being heated.

  (5) The perm rod has a triangular or quadrangular cross section.

  According to the present invention, hairstyles with different richness can be realized by a triangular prism having a triangular cross section and a quadrangular prism (including a flat thin plate) having a quadrangular (rectangular, square) cross section. In particular, since the stress from the corners that are not rounded in the triangle or quadrilateral is stronger than the cross section that approaches a circle such as a pentagon or hexagon, there is a stereoscopic effect with the corners emphasized locally. Waves can be formed.

  (6) A method of using a perm rod, wherein a plurality of perm rods are arranged opposite to each other to sandwich the hair.

  According to the present invention, it is possible to easily adjust the position of the hair when performing perm setting by arranging a plurality of perm rods so as to sandwich the hair.

  When the hair is wound around the prism, the permanent rod according to the present invention has a stronger stress from the corners that are not rounded. There is an effect that different hairstyles can be realized.
