Abstract

A correcting clip for perming the hair is formed into a clamp and constituted of a pair of handles and a pair of clip bodies. The lower handle is provided with an electric heater serving as the heat source of the upper clip body. The upper clip body is constituted of a plurality of protruding rings. There is a gap formed between each pair of protruding rings. In use, a hairdresser grips the upper clip body and the lower clip body to clip the hair coated with a correcting paste and to outwardly pull the clipped bundle of hairs, and with the clipping pressure and heat, the scales curled from the surface of the hair during the perm can be corrected to recover its original shape, thereby to recover the smoothness of the hair.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
Many women like to go to the beauty salon for a perm, and thus the perm has become a part of women's life. There are many kinds of methods for perming the hair. The perming procedure is substantially described as follows. First, the hair is subjected to a softening treatment. The so-called softening treatment is performed by coating a chemical reagent on the hair to slightly curl the scales on the surface of the hair (the hair is covered by a plurality of overlapped scales). As a result, the degree of the softness of the hair can be increase, thereby to facilitate the shaping of hairstyle. Then, the chemical reagent is heated again so that the hairstyle can be set. Finally, the correcting clip and another chemical reagent are used to smooth the scales curled from the surface of the hair during the softening treatment. As a result, the smoothness and the luster of the hair can be recovered. This is called the correcting step. Since the tool used in this correcting step has the clip shape, it is called a “correcting clip.”
2. Description of Prior Art
The conventional correcting clip used in hairdressers is shown in FIGS. 1 to 4. It is a clip formed into a long clamp and constituted of a handle and a clip body. The handle includes an upper handle (11) and a lower handle (12). The lower handle (12) is provided with an electric heater therein, and thus it is also called the heating handle. The electric power used for heating comes from an electric plug (4). The outside of the heating handle (12) is covered with a thick layer of insulator for insulating against heat so that the heating handle (12) can be still operated with hands when heated. The clip body also comprises an upper clip body (22) and a lower clip body (21) each formed into a flat shape, as shown in FIG. 4. In order to accumulate the heat, the upper clip body (22) is thicker than the lower clip body (21). The upper clip body (22) and the lower handle (12) are integrally formed of a material having good thermal conductivity, so that they can function as electric heaters. A small gap (23) is left between the upper clip body (22) and the lower clip body (21). When in use, after the correcting clip is heated by plugging the electric plug (4), a small bundle of hairs to be corrected is coated with a correcting paste and then clipped into the gap (23) of the correcting clip. With the heating energy of the upper clip body (22), the correcting paste is melted and infiltrates into the seams of the hairs. As a result, the correcting paste chemically reacts with the hairs to soften the scales curled from the surface of the hairs. With the heat and the clipping pressure of the upper clip body (22), the scales can be recovered. In this way, a hairdresser slowly clips bundles of hairs and pulls outwardly to correct the bundles of hairs. Therefore, the hairs can be corrected bundle by bundle to recover the original luster and smoothness. However, the major problems of such a conventional correcting clip lies in that the clip body and the clipped bundle of hairs are brought in a face-to-face contact, hence the heat and the pressure are only distributed over the surface of the clipped bundle of hairs, which means the pressure applied to a single hair is inevitably small and the pressure applied to the inner layer of the clipped bundle of hairs is much smaller. It is clear that the correcting effect of the conventional correcting clip is very poor and thus needed to be improved.

SUMMARY OF THE INVENTION

In view of the above, the inventor proposes the present invention to overcome the above problems based on his expert experiences and deliberate researches. In order to concentrate the clipping pressure and distribute the heat into the bundle of hairs more evenly, the structure of the clip body is modified. The description of the present invention is made with reference to the accompanying drawings. However, it should be understood that the drawings are illustrative but not used to limit the scope of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 5 is a front view showing the correcting clip of the present invention. FIGS. 6 and 7 are a top view and a bottom view respectively showing the correcting clip of the present invention. FIG. 8 is a cross-sectional view taken along the line 8-8 in FIG. 5, and FIG. 9 is an enlarged cross-sectional view showing the lower clip body (61). As shown in the drawings, the handle and the heating portion of the correcting clip of the present invention are similar to those in the prior art. The major difference is in the clip body. Therefore, the description relating to the structure of the handle is omitted for clarity. As for the clip body of the present invention, it is totally different from the clip body in the prior art. The upper clip body (62) and the lower clip body (61) are each formed into a rod shape. The electric heater of the lower handle (52) generates the heat of the upper clip body (62). The rod-like upper clip body (62) is constituted of a plurality of protruding rings. A gap is formed between each pair of protruding rings. When the correcting clip clips bundles of hairs, the bundles of hairs will be filled into the gaps between pairs of protruding rings. The protruding rings not only introduce the heat into the bundles of hairs, but also generate sideway pressure between each pair of rings. As a result, the scales curled from the surface of the hair by the softening treatment can be efficiently corrected under the chemical action, pressure and heat. Therefore, when the hairdresser grips the correcting clip to clip the hair coated with the correcting paste and gradually pulls the clipped bundles of hairs outwardly, all the bundles of hairs can be efficiently corrected.
The lower clip body (61) is also formed into a rod shape. Although the lower clip body (61) is not a heat-generating element, some heat will be still transferred onto the lower clip body (61), and it is painful when the lower clip body (61) touches the skin of head. Therefore, an insulator (611 ) is covered around the surface of the lower clip body (61), as shown in FIG. 9.
In the present invention, both the upper clip body (62) and the lower clip body (61) are formed into a rod shape. When the correcting clip clips the bundle of hairs, the clipped point exerts a point-to-point pressure on the single hair. Therefore, the pressure and heating effect of the present invention are stronger than those in prior art (the conventional correcting clip exerts a flat plane pressure on a bundle of hairs). In operation, the hairdresser grips the upper clip body (62) and the lower clip body (61) to outwardly pull the bundles of hairs, and the effects caused by the pressure and the heat can reach the whole bundle of hairs. Therefore, in comparison with the prior art, the correcting effect of the present invention is much better.
As shown in FIGS. 5, 6 and 7, the upper clip body (62) and the lower handle (52) are made of a metal having good thermal conductivity. Actually, these two elements are integrally formed. The electric heater is provided at a proper position of the lower handle (52), and a layer of insulator is covered on the outside of the lower handle (52). The lower clip body (61) and the upper handle (51) are integrally formed of a metal having low thermal conductivity. The pivot (3) is used to assemble the upper clip body (62) and the lower handle (52), and the lower clip body (61) and the upper handle (51) into the clamp-like correcting clip.
