Description

{Open Type Rod for Curing Hair}

The present invention relates to an open rod for hair curling, and more particularly, to an open rod for hair curing, and more particularly, to an open rod for hair curling which is free from foreign matters, It is possible to completely eliminate the risk of burning and explosion due to the expansion of the chemical solution for hair curing or moisture and to rapidly cool the hair by cooling air after curling so as to maximize the effect of perming treatment and minimize hair damage, And without any flow between the inner wall and the inner wall, it is possible to effectively transfer heat to the outer enclosure. Moreover, there is no fear of short-circuit or short-circuit of the heat ray due to the flow of the film heater. Opening for hair curling having superior reliability and durability Lt; / RTI >

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

On the other hand, permanent waving agents generally consist of a first agent containing a reducing agent as a main component and a second agent containing an oxidizing agent (neutralizing agent) as a main component.

The permanent waving (perm) mechanism of hair is the most basic step, by cutting the disulfide bond of cystine [HO ₂ CC (NH ₂ ) HCH ₂ S-SCH ₂ C (NH ₂ ) HCO ₂ H] using a first reducing agent (Reducing agent treatment step), and the hair is retained in a wave form by applying a mechanical tensile force to the hair before or after the treatment, at the same time as the cysteine [HO ₂ CC (NH ₂ ) HCH ₂ SH] And then converting the cysteine to a cystine by reversing the above reaction by applying a second oxidizing agent as a subsequent step to form a wave on the hair using the hair curling rod for subsequent hair curling, (Oxidation or fixing step).

The new form imparted to the hair by chemical treatment as described above is remarkably strong in consistency and is resistant to water and shampoo cleaning treatments for hair, so that, in contrast to simple and conventional non-papermaking hair treatment treatments such as hair setting Effect. The hair modification technique by chemical treatment described above can be applied both to impart a straightening hair (conventional perm), to straighten wavy hair to straight hair, or to unwrap a wave.

The first agent containing a reducing agent as a main component is usually provided in the form of a relatively viscous composition such as a waving lotion, a concentrate, a cream, a gel and the like. Typical examples of the reducing agent include cysteine and various derivatives thereof, cysteamine and its derivatives , Thiolactic acid, thioglycolic acid and its esters, in particular glycerol monothioglycolate, thioglycerol, and mercaptopropionic acid, and examples of the additives include nonionic, anionic, cationic or amphoteric surfactants known in the art And other ingredients such as a hair damaging agent, a dandruff inhibitor, a thickening agent, a suspending agent, an ionic blocking agent, a whitening agent, a dye, a sunscreen agent, a perfume and a preservative are usually added, and ethanol, propanol or isopropanol And a solvent such as glycerol.

On the other hand, a typical example of the oxidizing agent as the second agent is dilute sodium bromate or aqueous hydrogen peroxide solution (diluted aqueous solution of about 3% to 6%).

In the above-mentioned perming operation, the first agent, which is a viscous agent containing the reducing agent as a main ingredient, is uniformly applied to the hair by the manual operation, and then the hair is wound on the rod to apply a tensile force to the hair, Heating it for a predetermined time using a heater, applying the oxidizing agent evenly to the hair by hand, holding it for a predetermined time to neutralize it, and then cleaning it.

As a method for warming the hair wound on the rod for hair curling used in the above-described perming operation, a method of directly heating the hair by inserting a heating member into the inside of the rod is widely used because of its direct and effective effect.

7 is a perspective view of the conventional hair curling rod 1 ', wherein one end of the outer housing 10' is integrally closed and a sealing stopper 80 'is fitted at the other end thereof, '), And if the temperature rises above a certain level, the resistance increases to reduce the heat flow by decreasing the current flow in the device, and when the temperature becomes lower than a certain level, the resistance decreases and the PTC (Positive Temperature (Not shown) or a silicon hot-wire heater, and a copper plate or an aluminum plate for heat-conducting is disposed on the outer side of the heater. The heater includes a power jack (not shown) Not shown).

However, since the conventional hair curling rod 1 'has a relatively large weight due to the presence of the heater and the metal heat transfer plate having a complicated structure, there is a large inconvenience to the user due to pulling of the hair when the hair is wound, There is a problem of the increase in the manufacturing cost due to the increase in the number of parts and the number of air, and the sealing structure is essentially waterproofed to the stopper portion. Therefore, when it is dropped or thrown inadvertently due to use and handling, or due to waterproofing or incomplete injection molding In the presence of microcracks due to product defects, such microcracks are hardly visible to the naked eye, so that when the moisture of the first or second agent or the washing water penetrates into the hair curing rod 1 ' Since the volume is rapidly expanded by the heater which is heated to about 150 ° C after the gas which has been held up to the limit pressure is rapidly expanded, There is a danger of instantaneous explosion. In this case, not only there is a risk of serious burns and injuries, but also a serious problem that the internal heater is short-circuited or short-circuited to cause a failure, There is a fear that the effect of the perming operation is deteriorated because the rapid cooling of the rod 1 'for hair curing due to the presence of the closed heated air in the hair curling rod 1' after the interruption of the electric supply is not performed, And the like.

In order to reduce the weight of the hair-curling rod 1 'in the above-described conventional techniques and to reduce the manufacturing cost due to the reduction in the number of parts and the number of pockets, Japanese Laid-Open Patent Publication No. 2-168903 (published on June 29, 1990) As shown in Fig. 8, which has been disclosed in Registration No. 10-0478672 (registered on March 15, 2005), a rod 1 "for hair curling using a film heater 30" has been proposed.

The constitution is such that a cap portion 81 " formed integrally with the outer enclosure 10 ' at one side with the outer enclosure 10 ", the film heater 30 & 80 "), and a power jack 60 ".

The difference from Fig. 7 is that a film or sheet 31 made of a heat-resistant resin such as polyimide is formed on the inner circumferential surface of the outer housing 10 " as shown in Fig. 6 without using the above- And the film heater 30 or 30 " made up of the heating wire 32 and the connecting portion 33 serving as the connection terminal formed at the end thereof, are used in contact with each other to reduce the cost of the heating device due to the weight reduction and simplification of the structure The hair curing rod 1 " of Fig. 8 is also of the same sealing type as the hair curing rod 1 'of Fig. 7, and thus has the same serious problems as described above, 10 " of the film heater 30 " depends on the physical force to be spread in the form of a flat plate, the thermal conductivity of the film heater 30 " There is a risk of malfunction due to failure of the liquor or short or short circuit.
