Description

Rod for perm {ROD FOR PERMANENT WAVE}

The present invention relates to a rod for perm, and more particularly, in a rod used to form a permanent wave on hair, to form a strong C curl with only 1/2 rotation less than the number of revolutions when winding a conventional circular rod It relates to a perm rod that can more efficiently form a rich volume in hair by configuring it.

In general, permanent wave, called perm or perm, is a technique of maintaining a wave by modifying hair tissue by chemical action of a chemical solution.

Before the development of perm technology, heat wave technology was used to form temporary waves by curling hair in a cylindrical shape using an iron heated to a high temperature. However, compared to the heat wave method, which takes a long time to form the wave, the maintenance time is short and there are problems such as causing thermal damage to the hair.

Permanent waving is a method of easily forming waves by modifying keratin, a type of protein that makes up hair. Keratin in hair is composed of an elastic chain structure. When the chain is broken by applying an alkali chemical solution while it is rolled on a rod curler, the hair loses its elasticity in the curled state and is not restored to its original state. to form curls. In this state, when neutralized with an oxidizing agent, elasticity is restored in a state where the curl is fixed to the hair, and the wave is established.

The rod used for the permanent wave is a major tool that has a great influence on the style of the wave to be formed, and rods having various shapes and structures are provided according to the size or location of the wave.

As an example of the most commonly used rod for perm, Korean Utility Model Registration No. 20 - 0157397 has a known permanent rod in which protrusions and grooves are formed to fix rubber bands for fixing at both ends, and protrusions and grooves of the rod on one side A rod for permanent wave having a pair of fixtures having rod coupling protrusions and rod coupling grooves corresponding to each other coupled to both ends of the rod, and a means for fixing the rubber band to the fixture.

As another example, Korean Utility Model Registration No. 20 - 0348037 discloses a cylindrical rod having a predetermined length and diameter, and a long and thin shape having the same length as the rod and waving in a wavy shape, one end of which is extended and bent upward. A perm rod set composed of a gripping piece having a handle portion and a fixing pin composed of a gripping piece overlapping with the gripping piece so that the other end of the gripping piece is extended and bent to have a predetermined elasticity so as to have a predetermined elasticity.

As another example, Korean Patent Registration No. 10 - 0731926 discloses a rod for applying permanent waves to hair, in which a first handle is formed in a cylindrical shape through which the inside is penetrated and grooves are formed at both ends of one side. A rod body having a detachable groove formed on the outer circumferential surface of the other side, and a second handle portion extending in the longitudinal direction of the rod body and having fitting protrusions formed so as to be fastened in the fitting groove, respectively, to be rotatably fastened on the rod body. And, it constitutes a permanent wave rod set including a fixing clip member fitted to the other side of the rod body.

Korea Utility Model Registration No. 20 - 0157397 (1999.09.15) Korea Utility Model Registration No. 20 - 0348037 (2004.04.28) Korean Registered Patent No. 10 - 0731926 (2007.06.25) Korea Utility Model Registration No. 20 - 0260190 (2002.01.10)

A conventional perm rod to which the prior art is applied as described above is formed in a form of forming a cylindrical body, winding hair, and forming a curl using a chemical solution in a state in which hair is wound and fixed using a rubber band.

However, such a circular rod can form plentiful curls at the end of the hair shaft, but the number of turns increases toward the hair roots and the distance between the rod and the scalp decreases the strength of the curl at the hair root, so the sense of volume is noticeably weak. There is a problem with the cancellation.

Due to this problem, various types of root volume perm rods have been developed and provided, but in the case of a circular rod with a small diameter, the hair must be wound at least one turn to form a curl, so in particular, one turn at the root of the hair The above winding not only causes inconvenience in the procedure, but also has a problem in that small curls are strongly formed and twitching occurs.

In another prior art, a clamping piece or a fixing clip member is added to a circular rod to form curls more easily, but the improvement effect is only insignificant.

On the other hand, recently, a technique of forming a more powerful curl by forming a cross-sectional shape of a rod for perm in a square or zigzag shape has been provided.

However, such a rod for perm has a problem in that, when applied to the root of the hair, the corresponding part is flattened due to the plane formed in the rod, or angular marks or irregularities are formed in the middle of the hair, so that natural curls cannot be obtained.

Accordingly, the present invention was invented to solve the problems of the prior art as described above,

A hair root support unit 110 provided to induce hair to curve toward the inside of the ridge forming unit 120 while supporting the periphery of the hair root;

A ridge forming unit 120 that combines the hair root support unit 110 on the front side and forms a ridge protrusion 122 on the inside so that the hair is bent at an angle of 70 to 130 ° along the surface of the ridge unit,

A ridge cover portion 150 that is hinged to one end of the ridge forming portion 120 in the horizontal direction and has an inner molded ridge portion 156 corresponding to the outer shape of the ridge protrusion 122 to cover it from the upper side. and,

It is configured to include a hair support unit 160 coupled to the rear side of the ridge forming unit 120 to induce hair to be curved to the outside of the ridge forming unit 120, so that hair can be produced with only a small number of rotations of the rod body compared to the prior art. It is possible to achieve the purpose of forming natural and abundant volume.

The present invention provides a rod for perm capable of forming more voluminous waves by differentiating the structure of a rod used to form permanent waves in hair from the prior art.

In particular, the present invention forms a strong C curl from the vicinity of the hair root adjacent to the scalp with only 1/2 to 2/3 rotation compared to the technology of forming a weak wave even if the hair is wound more than 1 to 2 rotations like the conventional circular rod. There is an advantage in forming a richer and stronger ridge even when applied to a short length hair part, such as a volume perm at the root of the hair.

In addition, the rod for perm has different curl strengths at the location of the head to be treated, for example, the crown and the side, and the present invention is configured to correspond to the head by the structural characteristics of the front and rear of the rod, so that strong curls can be effectively performed on the crown and the side. There are benefits to forming.

In addition, the present invention has the effect of forming the best volume wave that is naturally connected from the root to the bottom of the hair by completely excluding problems such as hair being pressed or forming angular marks on a flat area like a conventional rectangular rod.
