Description

rod for perm

The present invention relates to a rod for perm.

The main component of hair is keratin, and keratin, a fibrous protein polymer composed of 18 different amino acids, is characterized by a cross-linked structure having an average of one disulfide bond (-SS-) per 10 to 20 amino acid residues. determines the tertiary structure of the protein by folding, and the representative of the keratin structure is cystine represented by the formula HO2CC(NH ₂ )HCH ₂ S-SCH ₂ C(NH ₂ )HCO ₂ H.

On the other hand, permanent waving agents are generally composed of a first agent having a reducing agent as a main component and a second agent having an oxidizing agent (hereinafter referred to as a neutralizing agent) as a main component.

Permanent waving (permanent) mechanism _of hair is the most basic step, and _the _first agent, _a reducing agent, is used to _cleave cysteine [ HO ₂ CC(NH ₂ )HCH ₂ SH] to transform the appearance of the hair (reducing agent treatment step), and apply mechanical tension to the hair before, after, or simultaneously with this treatment to maintain a wave shape A method of forming waves in the hair using a permanent rod (tensile force adding step), and then reversing the above reaction by applying a second agent, a neutralizing agent, as a subsequent step, thereby converting cysteine back to cystine, thereby fixing the hair into a wavy shape. (oxidation or fixation step).

The new shape imparted to the hair by the chemical treatment as described above has remarkably strong durability and is resistant to water or shampoo washing treatment for hair, so it is in contrast to simple and conventional non-permanent hair modification treatment such as hair setting. have an effect

In the above-described perming operation, the first agent, which is viscous containing the reducing agent as a main component, is evenly applied to the hair by hand, and then the hair is wound around the perm rod to apply tension to the hair from the heater in the rod and/or from the outside. After heating for a predetermined time using an infrared heater, the oxidizing agent is uniformly applied to the hair by hand, maintained for a predetermined time, neutralized, and then washed.

In recent years, as hair damage due to frequent perming and frequent use of shampoo with strong cleaning power, and frequent hair dyeing in various colors, etc. has become frequent, hair pulling during perming is relatively small, and the possibility of hair damage due to heating is relatively low. There is a trend of increasing preference for safer, lightweight and soft perma rods because there is no risk of accidents because it is not an electric heating type.

However, in the conventional perma rod, when the reducing agent as a relatively viscous first agent is applied to the hair wound around the rod, the oxidizing agent (neutralizing agent) as the second agent is difficult to uniformly penetrate into the deeply wound hair. There is a problem that a beautiful perm is not done.

In particular, if there is a lot of thinness, or if the perm is rolled at once by taking many sections, or if the perm has weak absorption, the neutralizer cannot penetrate deep into the depth of the curl, resulting in poor curl perfection.

To compensate for this, we neutralize the hair once more by loosening the hair on the rod. At this time, there is a problem of sagging of the curls, it takes a long time to unwind the perm, and it takes more time to do additional neutralization treatment This results in exceeding the optimum neutralization time of 7 minutes, which causes hair damage.

As shown, the body 10, the neutralizing agent inlet 30 formed on one side of the body 10, and a passage through which the neutralizing agent introduced from the inlet moves, are not connected to the other side of the body 10 The neutralizing agent connected to the main oil passage 40, a plurality of neutralizing agent outlets 20 formed on the surface of the body 10, and the main oil passage 40, and moved from the main oil passage 40, is the neutralizing agent. A plurality of floating passages 41 that are passages moving to the outlet 20; The central portion of the body 10 may be formed to be thicker than both ends, and a plurality of groove portions 11 may be formed at both ends to secure the wound hair with a rubber band.

The neutralizing agent inlet 30 is formed on one side of the body 10 , and the neutralizing agent inlet 30 is not formed on the other side of the body 10 . The user may inject the neutralizing agent into the neutralizing agent inlet 30 . The injection method is not limited, and may be injected using a syringe or a separate neutralizing agent injector.

The neutralizing agent introduced from the neutralizing agent inlet 30 flows into the body 10 through the main flow passage 40 . The main flow passage part 40 may be formed to be elongated in the longitudinal direction of the body 10 , and is not connected to the other side of the body 10 , and has a closed end (refer to reference numeral 50 in FIG. 2 ). The diameter of the main flow passage part 40 is not limited, but may be in the range of 1 mm to 10 mm. Below the above range, the pressure required for injection of the neutralizer increases, and it may take a long time to inject the neutralizer. When the above range is exceeded, the amount of neutralizing agent consumption may increase because there are many neutralizing agents remaining inside the body 10 .

The main flow passage 40 is connected to a plurality of floating passages 41 , and the floating passage 41 is connected to a plurality of neutralizer outlets 20 formed on the surface of the body 10 . The neutralizing agent flowing into the main flow passage 40 is filled in reverse from the end of the main flow passage 40 by the injection pressure and flow inertia, and then flows sequentially from the floating passage 41 far from the neutralizing agent inlet 30 . Thus, the neutralizing agent is discharged to the neutralizing agent outlet 20 . The arrangement and number of the neutralizing agent outlets 20 are not limited. Preferably, it is formed in the area where the hair is wound. Three to five pieces may be arranged spaced apart along the circumference of the body 10, and three to six pieces may be spaced apart along the length and arranged in an aligned form.

The farther the neutralizer outlet 20 from the neutralizer inlet 30 is, the more the neutralizing agent is discharged first to neutralize the hair. , it is possible to make the amount of the neutralizing agent penetrating into the hair more uniform (see FIG. 3 ).

In addition, the plurality of neutralizing agent outlets 20 may have a circular shape. Preferably, the length direction of the body 10 may be longer than the width direction of the body 10 . For example, as shown, it may have an oval shape or a rectangular shape with rounded corners. In this case, since the increase in the diameter of the main flow passage part 40 can be minimized while increasing the area of the neutralizing agent outlet 20 , the amount of consumption of the neutralizing agent remaining in the main flow passage part 40 can be reduced.

Optionally, the surface of the body 10 may further include a display unit 60 for identifying the side on which the neutralizing agent inlet 30 is present or the side on which the neutralizing agent inlet 30 does not exist. When the user winds the hair around the body 10, the neutralizing agent inlet 30 should have the same orientation, so that it is convenient to inject the neutralizing agent and the neutralizing agent processing time can be reduced. To this end, a display unit 60 indicating the side with or without the neutralizing agent inlet 30 is placed on the surface of the rod body 10 to enable quick and efficient perm work. The display unit 60 may be formed by a method such as color, printing, or three-dimensional mark.

Figure 4 is an exploded view of the perm rod according to another embodiment of the present invention. As shown, the body 10 may be detachably separated from each other into a first body 10a and a second body 10b. In addition, the interface through which the first body 10a and the second body 10b are separated may divide the main flow passage part 40 in two. In addition, all or a part of the floating passage part 41 may be divided into two parts. Since the rod body can be separated, it is easy to finely manufacture the main oil passage part 40 and the floating passage part 41 , and it is easy to clean the inside of the main oil passage part 40 and the floating passage part 41 . .

A coupling method for making the first body 10a and the second body 10b detachable is not limited. For example, the interface of the first body 10a has a plurality of protrusions 70 for detachment, and the interface of the second body 10b has a plurality of insertion grooves 71 into which the protrusions can be inserted. can be provided. The user can use the first body 10a and the second body 10b by combining and inserting the protrusion 70 into the insertion groove 71 by pressing, and after use, it can be separated and easily washed.

5 is a view for explaining a perm rod according to another embodiment of the present invention. As shown, the surface of the body 10 may be formed with a plurality of micro-channels 21 extending radially from the surface of the neutralizer outlet 20 . The micro-channel 21 may have a shape that is inserted to a predetermined depth from the surface of the body 10 . A portion of the neutralizing agent discharged from the neutralizing agent outlet 20 flows through the micro-channel 21 to neutralize the hair separated from the neutralizing agent outlet 20, so that a more uniform neutralization operation is possible.
