Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye applying brush suitable for applying a hair dye to the whole hair including the root of the hair.

[0002]

2. Description of the Related Art As shown in FIG. 10, a brush part 4 having comb teeth 3 arranged in a row in a container 2 for accommodating a hair dye is attached as a hair dye applying brush 1 via a connecting part 5. Is known. The comb tooth 3 has a flat plate-like shape with a tapered tip 6, and a liquid guide channel 7 communicating with the inside of the container 2 is formed inside the comb tooth 3. Also, comb teeth 3
A hair dye discharge port 9 is formed on the side surface (the surface facing the adjacent comb teeth).

According to this hair dye applying brush 1, the hair dye is discharged from the discharge port 9 of the comb teeth 3 by pressing the container 2, and the hair dye is applied to the hair, while the hair dye is applied to the hair. The hair dye can be easily applied to the hair as compared with the case where the hair dye container and the brush are separated from each other.

[0004]

However, in the conventional hair dye applying brush 1, in order to easily supply the hair dye to the root of the hair, the position of the discharge port 9 is changed as shown in FIG. When approaching the tip side of the comb teeth 3, the holding amount of the hair dye A discharged from the discharge port 9 between the adjacent comb teeth 3 decreases. For this reason, there occurs a problem that the work amount (the number of times of application) required for hair dyeing increases.

Conversely, when the ejection port 9 is moved toward the comb tooth base surface 8 as shown in FIG. 1B, the amount of the hair dye A held between the comb teeth 3 increases, but the amount of the hair dye A between the comb teeth 3 increases. Since the distance between the held hair dye A and the tip 6 of the comb teeth 3 becomes large, it becomes difficult to apply the hair at the root. In order to make it easier to apply the hair at the base of the hair, it is conceivable to shorten the tapered tip portion 6. However, if the tip portion 6 is shortened, it becomes difficult to comb the hair, and the feeling of combing becomes worse. In addition, the hair dye easily adheres to the scalp.

As described above, in the conventional brush for applying a hair dye, it is not possible to simultaneously improve the ease of applying the hair to the root of the hair, the reduction in the amount of work required for the hair dye, and the feeling of combing.

On the other hand, the present invention provides a hair dye application brush which dyes the root of the hair and the whole hair with a simple operation, reduces the adhesion of the hair dye to the scalp, and is excellent in combing feeling. The purpose is to do.

[0008]

Means for Solving the Problems The present inventor has proposed a brush for applying a hair dye in which a hair dye container and a brush part are integrated so as to face both sides of a row of hair dye outlets. The outer comb teeth were arranged in line, and the agent receiving member was provided vertically movable between the opposed outer comb teeth so that a liquid pool portion was formed between the discharge port and the agent receiving member. The hair dye is held in a sufficient amount here, and if the hair is further combed with this brush, the hair can be dyed with the hair dye held in the pool, and in this case, the hair is held in the pool. Since the agent receiving member is pushed up by the hair in accordance with the amount of the hair dye, it has been found that combing does not deteriorate.

That is, the present invention has a brush portion, a container for accommodating a hair dye, and a liquid guide passage between the brush portion and the container, which communicates with the inside of the container. A hair dye application brush comprising a connection portion in which hair discharge ports are arranged in a row, wherein a plurality of brush portions are provided so as to face both sides of the row of hair dye discharge ports. Provided is a hair dye applying brush including an agent receiving member that is held between an outer comb tooth portion formed of an outer comb tooth and an opposing outer comb tooth portion in a vertical direction and that forms a liquid pool portion.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or equivalent components.

FIG. 1 shows a brush 1A for applying a hair dye according to an embodiment of the present invention. FIGS. 2, 3 and 4 show the brush portion of the brush 1A for applying a hair dye, respectively. 4 shows an outer comb tooth part 30, a medicine receiving member 60, and a stopper 50 for fixing the medicine receiving member.

The brush 1A for applying a hair dye comprises a container 2 for accommodating the hair dye, a brush portion 4, and a connecting portion 5 for connecting the container 2 and the brush portion 4.

The container 2 is made of a flexible material from which the hair dye can be extruded by pressing. As such a flexible material, for example, a material having a flexible outer layer as disclosed in JP-A-2000-16470 and an inner layer releasably laminated on the outer layer is used. Preferably, air is introduced between the outer layer and the inner layer after the container is pressed, and the outer layer is restored to the shape before the pressing, and the inner layer is peeled and contracted and deformed. This eliminates the need for a dip tube, and allows the container 2 to be used either upright or inverted.

The connecting portion 5 has a liquid guide 2 for a hair dye therein.
0 is formed, and the hair dye discharge port 2 is provided on the brush part 4 side.
1 are arranged in a row. The connecting portion 5 may be formed integrally with the container 2 or may be a separate member.

The brush portion 4 is provided between the outer comb teeth 30 provided on both sides of the row of the hair dye outlets 21 and the outer comb teeth 30 in the vertical direction (outer comb). Tooth 31
(A rising direction) is held by the agent receiving member 60 movably.

The outer comb teeth portion 30 comprises a plurality of outer comb teeth 31 (FIG. 2A). Opposing outer comb teeth 30
Is partitioned in the longitudinal direction of the brush part 4 by a partition plate 35. Further, in this area, a comb holding tooth 36 is provided at a position between the agent receiving member 60 and the discharge port 21.

The agent receiving member 60 includes a T-shaped plate-shaped member 61.
Are arranged in a plurality of columns on the support column 62 at predetermined intervals (FIG. 3). The width a, the thickness b, and the width b of the plate-like member 61 are set such that a pool 63 holding the hair dye is formed in a region between the agent receiving member 60 and the discharge port 21 (FIG. 1E).
Interval c between adjacent plate members 61 (FIGS. 3B and 3C)
However, the viscosity of the hair dye to which the hair dye application brush is applied, the distance d between the opposing outer comb teeth 31 (FIG. 2D), the thickness b ₁ of the outer comb teeth 31, and the adjacent outer comb teeth 31 interval c
₁ (FIG. 2 (c)) and the like. In this case, a
<D, b ≦ b ₁ , and c ≧ c ₁ . Further, the plate-like member 61 is provided so that the surface direction thereof coincides with the direction connecting the opposing outer comb teeth 31 so that the combability is not deteriorated, and the pitch p of the plate-like member 61 (FIG. 3). (B)) is equal to the pitch p ₁ of the outer comb teeth 31 (FIG. 2 (c)).
As shown in (b), there is no phase shift in these pitches.

As shown in FIG. 5, the agent receiving member 60 is inserted between the opposing outer comb teeth portions 30 and both ends are pressed by stoppers 50, whereby the agent receiving member 60 is moved in the direction indicated by the arrow A (FIG. 1).
It is held up and down as shown in FIG.

When the hair dye applying brush 1A is used, when the container 2 is pressed, as shown in FIG.
The hair dye contained in the container 2 is pushed out from the discharge port 21 as shown by an arrow, and the agent receiving member 60 moves to the tip end side of the outer comb teeth 31, and the hair dye is held in the liquid reservoir 63. You. In this case, since the agent receiving member 60 is formed by arranging the T-shaped plate-like members 61 on the columns 62,
The hair dye discharged from the nozzle collides with the column 62 and flows in two directions as indicated by the arrows, and is evenly supplied to both of the opposing outer comb teeth 31. Further, the partitioning plate 35 and the comb teeth 36 for agent holding prevent the hair dye held in the pool portion 63 from moving in the longitudinal direction of the brush portion. Accordingly, the hair dye is not biased in the pool portion 63, and the hair dye can be applied to the hair satisfactorily even if the hair is combed from any part of the outer comb teeth portion 30.

Since the liquid guide path 7 in the comb teeth 3 is omitted as compared with the hair dye applying brush 1 of FIG. 10, the hair dye can be pushed out with less force. Since the hair dye discharged from the discharge port 21 is held in the liquid pool 63, it is also possible to prevent the agent from scattering when the hair dye is discharged.

When the brush 1A is moved along the scalp in a state where the hair dye is pushed out to the pool 63, as shown in FIG. 2
Move to one side. In this case, since the plate-shaped member 61 is T-shaped, the hair H reaches the support 62. Therefore, good combing is ensured, and the hair dye retained in the pool portion 63 is applied to the hair H without any residue. In addition, the agent-holding comb teeth 36 efficiently direct the hair dye held in the pool portion 63 toward the tip end of the outer comb teeth 31, so that the hair dye is satisfactorily supplied to the root of the hair. can do. Furthermore, regardless of the angle of the outer comb teeth 31 for combing the hair (the angle between the straight line connecting the opposing outer comb teeth 31 and the scalp),
A tip portion of the outer comb tooth 31 in contact with the scalp;
Since the distance from the hair dye held in is extremely small,
The hair dye can be reliably applied to the root of the hair. On the other hand, between the scalp and the reservoir 63, the plate-like member 6
Since 1 is interposed, adhesion of the hair dye to the scalp is prevented.

After the hair dyeing, the agent receiving member 60 is movable, so that the agent receiving member 60 can be easily washed. Further, by removing the stopper 50, the agent receiving member 60 can be removed from the outer comb tooth portion 30. And can be assembled as shown in FIG.

The present invention can take various other aspects. For example, in the hair dye application brush 1A of FIG. 1, the outer comb teeth 31 are provided in one row on both sides of the row of the ejection holes 21, but a plurality of rows may be provided. The agent receiving member 60 can also take various shapes. Therefore, like the hair dye application brush 1B shown in FIG. 7, the outer comb teeth 31a and 31b are provided in two rows on both sides of the row of the ejection holes 21, respectively. two large and small plate members 61a, 61
1b may be provided alternately. This hair dye application brush 1
B, as shown in FIG.
The hair dye is held in the pool 63 between the nozzle hole 0 and the discharge hole 21. By moving the hair dye along the scalp, FIG.
As shown in (b), the agent receiving member 60 is pushed by the hair H and moves toward the discharge port 21, so that the hair dye is supplied to the root of the hair while preventing the hair dye from adhering to the scalp. be able to. In addition, the feeling of combing can be further improved as compared with the hair dye application brush 1A of FIG.

The shape of the plate-like member 61 constituting the agent receiving member 60 may be Y-shaped as shown in FIG. Also in this case, the hair dye discharged from the discharge hole located on the support column 62 can be divided into two directions as shown by arrows in FIG. 6A, and can be uniformly supplied to both of the opposing outer comb teeth. it can.

In order to equalize the amount of the hair dye discharged from the plurality of discharge ports 21, the diameter of the liquid guide path 20 in the connecting portion 5 may be increased as the distance from the container 2 increases. May be widened as far as the container is.
