Description

[Detailed explanation of the idea]

The present invention relates to a hairbrush, and more specifically, to a hairbrush in which brittles are radially dispersed and flocked in a bristle part of a base and are arranged in a staggered manner with three or more rows of brittles in the gauge direction or pitch direction as one repeating unit. The purpose of this invention is to provide a hairbrush that has excellent hair retention properties even when used on short hair, and has extremely good hair separation during blow-drying. Conventionally, hairbrushes for blow-drying hair to style the hair while drying the hair using a hair dryer have had brittle flocking on the base, usually called the handle, with brittle all around the entire circumference or around the area. Two rows of flocked hair are used in the area in a staggered manner. However, roll brushes that use animal hair as bristles (brittle flocked around the entire circumference) have a large number of bristles per flocking hole, making it difficult to scoop the hair when creating a hairstyle during blow-drying. It has the disadvantage of poor retention and insufficient curling. 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 using animal hair, plant one molded bristle or two filament-shaped plastic bristle.
- All of the roll brushes with 4 brushes etc. have excess hair tangled and are uncomfortable to use, so there is no substantial improvement. Also, the so-called half-round brush, which has hair planted in an area of about 1/4 of the circumference, is easy to scoop hair and has less tangles, but on the other hand, it has poor ability to hold hair in bristles and has very poor curl-forming ability. . In this way, hair brushes used for blow-drying the hair while drying the hair using a hair dryer have not yet been found to be satisfactory, and improvements and developments are desperately needed among consumers. ing. 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 determined that the bristles, which are radially dispersed and flocked in the flocked part of the base, are placed in special relative positions. We discovered that a hairbrush for blow-drying with flocked hair has good hair retention properties, especially when used on short hair, and that the hair comes apart very well when the hairbrush for blow-drying is removed from the hair, and the present invention was developed. completed. That is, the present invention provides a blow-finishing hairbrush having a base consisting of a bristle-flocking part with a circular cross section and a grip part connected to the bristle-flocking part, in which the bristle is attached to the periphery of the bristle-flocking part.
The bristles are radially implanted in a phase range of 210 to 270 degrees, and the bristles near non-implanted areas are shorter than the bristles implanted in other areas, and the bristle is radially dispersed. The flocked brittle has two or more rows of other brittle within one pitch or one gauge (preferably two or more rows).
or 3 rows) are arranged in a staggered manner as a repeating unit of 3 or more rows (preferably 3 or 4 rows) (i.e., 3 or more rows of brittle in the gauge direction or pitch direction The present invention provides a blow-finishing hairbrush (characterized in that the hairs are flocked in a staggered manner as units). In the present invention, "pitch" refers to a repeating unit of the bristle flocking position in the direction of the handle of the hairbrush, and "gauge" refers to a repeating unit of the bristle flocking position in a direction that is 90 degrees to the handle direction of the hairbrush. In the hairbrush of the present invention, it is preferable to have one brittle per bundle, that is, one in which the bristles are dispersed and planted radially. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The hairbrush of the present invention may be molded by integrating the brittle and the handle body, but from the viewpoint of workability, the brittle sheet described below may be flocked to a sheet, or the brittle sheet may be formed by integrally molding the brittle and the sheet. It is best to attach it to the handle of the hairbrush. Fig. 1 is a plan view of the bristle sheet of the hairbrush according to the present invention, showing the relative arrangement of the brittle, with the horizontal direction in Fig. 1 representing the gauge direction, and the vertical direction representing the pitch direction. In Fig. 1, the bristles 2 are flocked in a staggered manner in three rows, with the other two rows being flocked between one pitch or one gauge, and three rows of brittle forming one repeating unit. It is something that Such a three-row staggered arrangement is most preferable for implementing the present invention. In contrast, Fig. 2 shows the conventionally used 2
This is a plan view of a bristle sheet in which the bristles are flocked in staggered rows, and only one row of other brittle 2' is flocked between one pitch or one gauge. In the staggered arrangement of the present invention, the pitch interval in the pitch direction of each repeating unit is not particularly limited, but is preferably 2 to 10 mm, more preferably 2 to 5 mm.
mm, most preferably 3-4 mm. On the other hand, the gauge spacing in the gauge direction is preferably 1.5 to 10 mm;
More preferably 1.5 to 5 mm, most preferably 2 to 5 mm
It is 3mm. In the present invention, hair transplantation is interpreted in a broad sense as already stated. That is, it includes not only simply planting bristle but also providing bristle in the flocked area. Therefore, as shown in FIG. 4, the method of flocking may be to directly plant the brittle 2 into the flocking hole 6 provided in the flocking part of the base using a pin 7 to form the flocked part 1, or As shown in Figure 3,
By inserting the brittle into a support base 4, such as a flexible sheet or plastic plate, which has holes for the brittle 2 to pass through, so that the bristles penetrate the hole and flocking, and by winding the support base 4 around the flocked part of the base. A flocked portion 1 may also be formed. 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. FIG. 5 is a cross-sectional view of the bristle-flocked portion 1 of an embodiment of the hairbrush of the present invention, and the bristles 2 are not flocked all around the bristle-flocked portion of the base. Fig. 5 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 changes. FIG. 6 is a longitudinal cross-sectional view taken in the directions indicated by X and Y in FIG. 5, and shows that the bristles 2 are not uniformly flocked in the portions shown in FIG. 5. Furthermore, the length of the brittle in Fig. 5 increases sequentially from the left end of the flocked brittle to the fifth brittle in a clockwise direction, and then decreases to the right end brittle, changing continuously. ing. In the present invention, as shown in Fig. 5, the brittle is transplanted in a phase range of 210 to 270 degrees with respect to the periphery of the transplanted part, and the brittle near the part where the brittle is not transplanted is transplanted to another part. It is shorter than the current Blitzle. In this case, it is suitable that at least one row of bristles with the maximum length is present, or that at least 80% of the total number of bristles is of the maximum length. The longest length of the brittle is 10 to 25 mm, and the shortest length is 3 to 20 mm, and the ratio of the maximum length to the minimum length is in the range of 1:0.3 to 1:0.8. Even better properties and usability. In this invention, it is easy to use a base with a diameter of 10 to 25 mm, and a thickness of bristle 2 of 0.5 to 2 mm.
It is easy to use an exposure length of 10 to 25 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 9 to 40 hairs/cm ² and the length of the flocked part 1 in the range of 50 to 100 mm. Thus, the hairbrush of the present invention uses a special staggered arrangement of the brittle as shown in Fig. 1 for the brittle which is radially dispersed in the transplanted area and the length of the bristles as shown in Fig. 5. As a result, it exhibits excellent hair retention properties and good hair separation when blow-drying, especially when used on short hair, and is extremely convenient in practice. Experimental example The brushing force of a Japanese hair bundle (length 29 cm, weight 20 g) was measured using a strain gauge twice after shampooing and rinsing, towel drying, and further drying with a hair dryer. . The brushes used were a product of the present invention with a pitch width of 3.5 mm and a 3-row staggered arrangement (Fig. 1), and a comparative product with a pitch width of 3.5 mm and a 2-row staggered arrangement (Fig. 2).

[Table] As is clear from the table above, the product of the present invention (three-row staggered arrangement) has a larger brushing force and superior hair retention power than the conventional two-row staggered arrangement (comparison product). show.
