Description

[Detailed Description of the Invention] The present invention relates to a hairbrush, and more specifically to a hairbrush having a base consisting of a bristle-flocking part and a gripping part, in which the bristle is radially dispersed one by one per bundle. The hair is transplanted in a range of 210 to 270 degrees around the transplanted area, and
The present invention relates to a blow-finishing hairbrush characterized in that the brittle near the non-flocked part of the brittle is shorter than the brittle in the other part.

Traditionally, hair brushes for blow-drying use a hair dryer to finish the hairstyle while drying the hair, and the bristles are implanted radially around the entire circumference of the base, which is usually called the handle. Alternatively, hairbrushes with flocked hair in an area of about 1/4th of the circumference are commercially available, and the former is commonly called a "roll brush" and the latter is called a "half-round brush."

However, roll brushes that use animal hair have a large number of bristle per tufted hole, making it difficult to scoop the hair when creating hairstyles during blow-drying, poor retention of hair in the bristle, and insufficient curls. It has the disadvantage that it is not. Furthermore, it has the disadvantage that excess hair gets tangled, the hair is pulled, and the skin becomes painful, which makes it uncomfortable to use.

On the other hand, instead of animal hair, one molded bristle or two filament-like plastic bristle can be planted.
All of the roll brushes with four brushes, etc., have excess hair tangled, are difficult to curl at the hairline, and have a poor usability, so there is no substantial improvement.

In addition, half-round brushes can easily scoop hair and have less tangles, but on the other hand, they have poor ability to hold bristle hair and have very poor curl-forming ability. Furthermore, it is difficult to curl short hair or hair at the hairline, and the tip of the brittle touches the skin, making it uncomfortable to use.

In this way, the hairbrushes used for blow-drying the hair while drying the hair using a hairdryer are still unsatisfactory, and even among consumers there is a strong desire for improvements and developments. has been done.

As a result of intensive research into a blow-finishing hairbrush that satisfies both curl-forming ability and workability, the inventors of the present invention have placed one bristle per bundle in a radial pattern of 210 mm around the base bristle part of the hairbrush. We have completed the present invention by discovering that hair transplanted in the range of ~270 degrees and varying the length of the bristle significantly improves both the ability to form curls and workability regardless of the length of the hair.

The hairbrush of the present invention has a base in which the bristles and the grip are integrally molded or these parts are jointly molded, and the area around the bristles on this base is
One bristle is implanted radially in each bundle at 210 to 270 degrees, and the bristle near the non-planted part of the bristle is shorter than the bristle that is implanted in other parts. . The length of the bristle of the hairbrush according to the present invention can be characterized by a cross section of the bristle part of the hairbrush. That is, the preferable feature of the bristle of the present invention is that the length of the bristle is successively longer from one end of the implanted bristle in the transverse cut plane, and has a single or plural longest bristle, and then becomes successively shorter. The hair is planted in such a way that it reaches the other end.

A brush in which the brittle lengths are successively shortened according to the present invention is significantly superior in curl forming ability and ease of use as a blow brush, compared to a brush in which all brittle lengths are the same. This is presumed to be due to the following reasons.

That is, when curling short hair or hair at the hairline to form a hairstyle, it is first necessary to grip and fix the hair with bristle. In the case of a hairbrush where the bristle in the vicinity of the non-grafted area is the same length as the bristle in other areas, the length of the bristle is the same, so the amount of hair that can be grasped will be sufficiently large, but The hair cannot be secured sufficiently because a gap is created between the scalp.
Furthermore, when trying to bring the transplanted part close to the scalp in order to fix the hair, the brittle presses the scalp, resulting in a significantly poor feeling of use. On the other hand, the hairbrush of this invention can sufficiently fix the hair, so
As a result, it is particularly effective in curling short hair or hair at the hairline, and also has a good feeling of use because it does not press the scalp with brittle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of the bristles 1 of the hairbrush of the present invention, and the bristles 2 are not flocked all around the bristle part of the base; This shows that the hair is implanted only in a specific range of 210 to 270 degrees, as exemplified from the starting point A to the end point B, and that the length of the brittle around the implanted area is changing.

Figure 2 shows the invented hairbrush in Figure 1.
This is a longitudinal cross-sectional view taken along XY in the indicated direction, and the brittle 2 shows that the portions of FIG. 1 which are not flocked are not uniformly flocked.

Now, the change in the length of the bristle, which is a feature of the present invention, is shown in FIGS. 1 and 3. The length of the brittle in Figure 1 increases sequentially from the left end of the grafted brittle to the fifth brittle in a clockwise direction, and then decreases to the right end brittle, changing continuously. This is an example showing that Figure 3 shows three rows of flocked bristle on the left and right sides, each with the left and right ends of the flocked bristle having the shortest length, and increasing in length as they move toward the top. is an example showing that the brittle in the third row has the same length.

In the hairbrush of the present invention, the total number of flocked rows around the flocked part is preferably 5 to 20, and the number of bristles with the maximum length is at least one row, or maximum 80% of the total number of flocked rows. It is appropriate that it is within the range. The longest length of the blitzle is 10 to 25 mm, and the shortest length is 3 to 20 mm.
A ratio of maximum length to minimum length of 1:0.3 to 1:0.8 provides the best curling ability, workability, and usability.

In the present invention, hair transplantation is interpreted in a broad sense.
That is, it includes not only simply planting bristle but also providing bristle in the flocked area. Therefore, as shown in FIG. 5, the method of hair transplantation may be to directly plant the bristle 2 into the bristle hole 6 provided in the flocked portion of the base 1 using pins 7 (see Fig. 5).
), or as shown in Figure 4, Blitzle 2
The bristle 2 is mounted on a support 4 such as a flexible sheet or plastic plate with holes 7 through which the bristle 2 is inserted.
The flocked part 1 may be formed by inserting the hair from the back side of the support base 4 so as to penetrate the hole and wind the support base 4 around the flocked part of the base 1. At this time, in order to stabilize the bristle 2, it is preferable to provide a flat plate portion 8 as shown in FIG. 4 at the lower end of the bristle. This effectively prevents the brittle from coming off even if stress is applied to the brittle during brushing, improving durability. Note that a filament may be used instead of the pin 7. Furthermore, known flocking methods such as manufacturing by integrally molding the whole can also be used.

Furthermore, in order to protect the hair more effectively, it is preferable that one end 5 of the bristle is not exposed on the base surface as shown in FIG.

In the present invention, the shape of the base is not particularly limited. Preferably, the flocked portion of the base has a circular cross section. It is easy to use a base with a diameter of 10 to 25 mm, and a bristle 2 with a thickness of 0.5 to 2 mm.

The material of the base and the bristle may be plastic or metal, and a wooden handle may also be used.

It is easy to use the flocking density of Britsutle 2 in the range of 3 to 25 hairs/cm ² and the length of the flocked part 1 in the range of 60 to 100 mm.

In this way, with short ends, short hair and hair at the edge of the hair can be easily aligned, making it easier to finish the hairstyle as desired.

Examples and Comparative Examples The hairbrush of the present invention with 9 vertical bristle rows (the cross-sectional angle between each row is 30°, therefore, the bristle is implanted in a range of 240° around the bristle part) shown in Fig. 1 was used as a base. The length of the flocked part is 80mm, the diameter is 15mm, the diameter of the bristle is 1mm, the number of lateral flocking rows is 20, the length of the bristle is 15mm, 18mm, 20 in the clockwise direction from the left end of the flocked bristle.
mm, 22mm, 25mm, then 22mm, 20mm, 18
It was made in such a way that it decreases to 15 mm. As a comparison product, a hairbrush similar to the above-mentioned product of the present invention was made, except that the length of all brittles was 25 mm.

After shampooing and drying a strand of hair with a length of 15 cm and a weight of 20 g, use the above-mentioned product of the present invention or a comparative product to scoop the hair by rotating the brush half a turn, then brush the hair, and measure the force required for brushing with a strain gauge. It was measured.

When this hair is scooped and combed, the value of brushing force (average of 10 times) is 568 ± 22 g for the comparative product and 829 ± 18 g for the invented product, which shows that the invented product has a greater power to fix the hair. .
