Abstract

PROBLEM TO BE SOLVED: To provide a permanent rod that does not allow any mark of a rubber band to remain on the hair. SOLUTION: The permanent rod 10 comprises a cylindrical body 2 and a plurality of rubber band anchoring sections 3 formed in each of the opposite ends of the body 2. An annular projection 11 having a diameter larger than that of the body 2 is formed near each of the ends of the body 2. The hair wound around the rod 10 is held in a space between a rubber band 7 and the body 2. The hair is not strongly bent by the rubber band 7, so that any mark of the rubber band 7 does not remain on the hair after perming.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent rod, and more particularly to a permanent rod of the type in which hair is wrapped around a rod and secured with rubber bands.

[0002]

2. Description of the Related Art A conventional permanent rod is shown in FIG. The permanent rod 1 shown in the figure is made of plastic, and has a cylindrical main body 2 that tapers toward the center.
And a rubber band locking portion 3 formed as a plurality of recesses at both ends of the main body 2. A plurality of grooves 4 extending in the major axis direction are provided on the surface of the main body 2, and knurled non-slip portions 5 are formed at the center and both ends between the grooves 4. . There are various types of permanent rods having such a configuration, from those having a small diameter to those having a large diameter, and it is possible to select one having an arbitrary thickness according to the purpose.

When applying a permanent, first, the hair 6 is wrapped around the permanent rod 1 together with a paper (not shown) as shown in FIG. After wrapping near the scalp, a rubber band 7 is laid between the left and right rubber band locking portions 3 and 3 in parallel with the scalp to fix the hair so that it does not come loose.

Then, in this state, the perm solution is applied and the perm is applied. At this time, since there is the groove 4 in the long axis direction, the liquid medicine spreads evenly over the entire hair, preventing unevenness of perm. Further, the hole at the center of the permanent rod 1 absorbs the excessive chemical liquid, and prevents excessive dusting of the hair tips.

[0005]

However, in the above-mentioned conventional permanent rod, as shown in FIG.
When the rubber band 7 is stretched between the rubber band locking portions 3 and 3 on both sides, the space 8 formed between the rubber band 7 and the main body 2 is very small. Then, when the hair 6 is wrapped around the permanent rod and stopped by the rubber band 7, the rubber band 7 tries to push the hair 6 into this small space 8, so that a strong tensile force acts on the rubber band 7.

A strong pulling force is also generated on the hair 6 itself due to the pulling force of the rubber band 7, and the rod 1 is about to be rotated in the direction in which the hair 6 can be unraveled. That is, as shown in FIG. 5, the rod 1 wound up to near the scalp 9
Is greatly rotated by the hair 6 in the direction opposite to the winding direction, and the hair of the part A in particular is strongly bent.
Then, after the perm was applied, the rubber band 7 was left on the hair.

The present invention has been conceived from the above facts, and an object thereof is to provide a permanent rod which does not leave a rubber band mark on the hair.

[0008]

In order to achieve the above object, the present invention provides a permanent rod having a cylindrical main body and a plurality of rubber band locking portions formed at both ends of the main body. It is characterized in that a convex portion protruding in the radial direction from the main body is formed near both ends of the main body.

Further, it is desirable that the convex portion has a ring shape or the main body has a shape that gradually becomes thinner toward the central portion.

Lift a bundle of hair in a direction perpendicular to the scalp, stack paper on one side, and apply a rod on the opposite side of the paper,
Wrap the hair around the rod with the paper and roll it up to just before the scalp. Since the hair bundle is pulled up in the vertical direction of the scalp, the rod around which the hair is wrapped is almost directly above the hair bundle. Therefore, hang a rubber band parallel to the scalp and fasten it. The rubber band is bridged between the convex portions on both sides that protrude in the radial direction, and a space larger than that of the conventional one is formed between the rubber band and the rod body. The hair wrapped around the rod is either entirely accommodated in this space or only slightly protrudes, and since the space is large, the hair can be held lightly so that it can not be loosened, and the excessive force as in the past is applied. Disappear. Therefore, even if it is stopped with a rubber band, the amount of the rod that reverses and returns with respect to the winding direction is very small, and no trace of the rubber band remains on the hair after perming.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a permanent rod 1 of the present invention.
Indicates 0. The rod of the present invention is characterized in that the protrusions 11 are formed on both ends of the conventional rod. This convex portion 11 is
It has a ring shape surrounding the entire circumference of the body 2 of the rod, and its diameter D is larger than the diameter d of the thickest part of the rod.

FIG. 2 is a view showing a state in which the hair 6 is wound around the rod of FIG. Since there are convex portions 11 on both sides of the rod, a space 12 formed between the rubber band 7 and the rod body 2
Is wider than the conventional space 8 (see FIG. 4). Therefore, all the wound hair 6 is accommodated in this space 12, and a gap is formed between the hair 6 and the rubber band 7.

FIG. 3 is a side view showing a state in which the hair 6 is wound around the rod 10 of the present invention. With the rod of the present invention, the hair 6 is separated from the rubber band 7,
The pulling force generated on the hair 6 becomes small, and as shown by the arrow in FIG. Therefore, unlike the conventional example shown in FIG. 5, the portion A is not strongly bent. In this way, the convex portion 11
By forming the, the rubber band 7 is not marked on the hair after the permanent is applied.

In some cases, the wound hair 6 may protrude from the space 12, but even in such a case, the amount of protrusion is much smaller than in the conventional case.
If you lightly press it with the rubber band 7, it can be stored in the space 12,
The amount of reverse rotation of the rod 10 is also small. Therefore, the hair is not bent excessively, and no rubber band marks are left after the perm.

In the embodiment of FIG. 1, the protrusion 11 is ring-shaped and is formed on the entire circumference of the rod, but it may be formed intermittently only on the rubber band engaging portion 3.

[0016]

According to the present invention as described above,
In the permanent rod, the protrusions that protrude in the radial direction from the main body are formed near both ends of the main body of the rod, so the space between the rubber band and the rod main body is widened, and the hair wrapped around the rod is strongly protected by the rubber band. Since it does not tighten, the rod does not reverse the direction of unwinding the hair and strongly bends the hair, and after applying the permanent, the mark of the rubber band does not remain on the hair.
