JP2002000338A - Hair setting tool - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a hair setting tool which is handy, functional, suitable for setting one's hair and innovative, quite different from the conventional combs or brushes. SOLUTION: In an extended part made of polypropylene of at least two hinged grooves parallel with each other, a comb pair standing in a direction at right angles to the extended part is integrated with the hinged grooves in a state that the teeth of one comb are engaged with those of the other comb. The space between each tooth is at least equivalent to the width of a tooth and not more than the twice of it, and the space between these two hinged grooves is more than 1.1 time as large as the comb thickness, and less than 5 times. The total width of these two grooves is two times wider than their total depth. The whole body is formed like a thin plate, and the tip teeth part is placed between each tooth, with the space two times large them the width of the tooth. The cross section of these two hinged grooves looks like a W shape, and when they are folded inwardly, the combs contact each other to cover double-layered over the gaps between each tooth. Other materials may be blended with the polypropylene material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comb or hairbrush-like hair styling tool having a unique function.

[0002]

2. Description of the Related Art Conventionally, a comb has been regarded only as a tool for combing paper, and a hairbrush for brushing has been prepared as another product. At present, it is hardly seen yet.

[0003]

Under these circumstances, even if the product is folded or attached to a case, or a shoehorn or a key ring is attached, it is not cohesive, and as a self-contained unique functional product, it has its own personality. Chipping and a comfortable feeling of use could not be obtained. SUMMARY OF THE INVENTION It is an object of the present invention to solve such a problem and to provide a new type of hairdressing tool having unique functionality and good usability.

[0004]

SUMMARY OF THE INVENTION A polypropylene molding P provided with at least two hinge grooves 1 parallel to each other.
A pair of combs A and B having one tooth A2 inserted between the other teeth B2 so as to face each other from a direction perpendicular to the groove 1 so as to be integrated with the hinge groove 1. .

[0005] Here, each inter-tooth width is formed so as to be equal to or more than the tooth width to less than twice, and the interval between the two hinge grooves 1 is set to 1.1 to less than 5 times the comb thickness. And the sum of the widths of the two hinge grooves 1 exceeds twice the sum of the depths. The interval between the hinge grooves 1 is measured at the deepest part of both grooves.

[0006] Further, the whole is formed in a thin plate shape, the inter-tooth width is at least twice the tooth width at least at the tips of the teeth A2 and B2, and the cross-sectional shape of two hinge grooves 1 is W.
So that when it is bent inward, a pair of combs A and B overlaps each other without any gaps.

Further, another functional substance is mixed in the material of the polypropylene molded product P to form the same.

[0008] Here, the term "integrally" means that the combs A,
The teeth of B may be integrally formed of the same polypropylene as the hinge groove, or may be formed of another material and then integrated by simultaneous or two-color molding or secondary processing.

Although the bottom of the hinge groove 1 is desirably V-shaped, it may be U-shaped. Even in this case, it is assumed that two rows form a W shape.

The term "another functional substance" refers to a substance other than polypropylene having hinge properties, such as an aromatic material, a pyroelectric mineral powder such as tourmaline, a phosphor, a thermosensitive material, and a pearl color-like material. And other special coloring materials, antibacterial materials and the like.

[0011]

[Operation and Effect] Since the present invention has such a configuration,
First of all, it is possible to obtain a hinge (hinge) with the groove formed in it as a fold because of the properties of polypropylene resin, but it is possible to fold it on both front and back sides by making it two hinge grooves parallel to each other In order to make it smoother, it is possible to prevent bending habits caused by repeated bending on only one side, and at the same time, by selecting the conditions for forming the two grooves, it is possible to achieve a high level that can withstand actual use as described below. It can be a "new comb" of functions.

That is, the interval between the two hinge grooves is made 1.1 to less than 5 times the thickness of the comb, and the total width of the two grooves is more than twice the total depth. Then
When these two hinge grooves are bent, each becomes 90
In this case, the teeth of the two combs are bent in the same direction by bending at 180 ° in total, but at this time, there is always an interval between the rows of teeth. Even if it is less than (twice or more) the width of the teeth, sufficient spacing between the teeth is substantially maintained so that there is no hindrance to combing. Also, if the width of the hinge groove is exactly twice the depth, it should bend exactly 90 ° mathematically, but in fact it increases rapidly as the deformation resistance of the resin material in the groove portion approaches 90 °. Therefore, it becomes difficult to use. However, when the groove width exceeds twice the depth as in the present invention, the resistance does not increase so much even in that state, and the usability is extremely good. (

FIG.

(See FIG. 5)

Further, by making the cross-sectional shape of the two hinge grooves into a W-shape, the two comb-like bodies are overlapped with no gap when folded in the same manner as described above, and the interval between the teeth is eliminated. In this case, since the interdental width is at least twice at least at the end of the tooth width, a sufficient gap is maintained between the teeth even when the tooth rows overlap, and the comb can be easily used. In this case, it is also possible to form a literally card-like object as a whole which is extremely thin and has no irregularities, and since it can be folded on both sides, there is no tendency to bend. (

FIG.

(See FIG. 6)

Furthermore, in the present invention, since the movement changes by 180 degrees on both sides through the hinge groove of polypropylene, the outline is gently gathered to make it more suitable for carrying. There is an effect that the functional substance put inside can more easily exert its function.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The hair styling tool of the present invention is manufactured by injection molding of polypropylene according to the specifications as described above. As a specific shape, there can be mentioned a thin card shape as shown in the drawing, but there are various other shapes such as a circular shape, a square shape, an elliptical shape, a diamond shape, and a plate gum shape. It is also optional to provide a handle, a sculpture, or an accessory.

A specific example of a hinge groove in such an overall shape will be described. That is, 1.5 mm between teeth,
When the thickness of a comb having a tooth width of 1 mm is 1.5 mm, 2
Each hinge groove has a width of 1.4 mm and a depth of 0.6.
mm, and the interval between both grooves is 3.5 mm at the deepest part.
And This forms a convenient brush-like double row comb.

Further, as another example, the tooth width is 3 mm, and the tooth width is 1 m.
m, and the whole including the hinge groove is made into a thin plate having a thickness of 1 mm, and each of the two hinge grooves has a width of 1 mm and a depth of 0.4.
mm V-cut, and the distance between them is 1 at the groove bottom.
mm, and the cross section is W
So that This forms a flat card-like, easy-to-use comb.

Further, in each case, a special fragrance pellet is mixed into the polypropylene material and the mixture is similarly molded. This emits a scent from the hinges and teeth with the bending operation during use. Expect negative ion effect by mixing tourmaline powder,
Certain types of fluorescent or light-collecting dyes are mixed to enhance the beauty of the movement of the dentition during bending.
