BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A specific embodiment of the present invention will be described. FIG.
FIG. 2 is a partial sectional front view of the hair dyeing cap according to the first embodiment of the present invention, FIG. 2 is a partial sectional side view, and FIG. 3 is a plan view. As shown in FIGS. 1 to 3, the hair dyeing cap 1 includes a covered cylindrical base 10 and a comb 20 erected on the base 10, and these are formed of synthetic resin. ing.

The base 10 has a thread groove 14 formed on the inner peripheral surface thereof, and the thread groove 14 is screwed with a thread (not shown) formed on the outer peripheral surface of the mouth portion of the container. Also, the base 1
0, on the inner surface of the lid portion 12, the inner periphery of the mouth portion of the container (not shown)
And a fitting ring 16 is provided to enable liquid tightness with the container. At the center of the lid 12, an opening 1
1 is formed.

The comb portion 20 is provided on the lid portion 12 and has an opening 11
And a plurality of comb teeth portions 24 protruding from the upper surface of the housing portion 22. Each comb tooth portion 24 has a hollow portion 25, and a discharge port 26 is provided at the tip. The discharge port 26 communicates with the inside of the container via the hollow portion 25, the liquid storage chamber 21, and the base 10. Desirable intervals, number and size of the comb teeth portions 24, and desirable diameters of the discharge ports 26 are as follows. First, the distance A between the comb teeth 24 shown in FIG. 1 is preferably 1 to 5 mm, more preferably 2 to 5 mm.
４4 mm. If the interval is too narrow, the hair will be easily caught on the hair and it will be difficult to apply the hair dye solution.On the other hand, if the interval is too wide, the resistance received from the hair will be small and it will be difficult to apply the hair dye solution along the hair. Not preferred.
The number of the comb teeth 24 is preferably 3 to 7, and more preferably 4 to 6. If the number is too small, the range that can be applied at one time is narrowed, and the working efficiency tends to be poor. If the number is too large, the hair dyeing liquid is applied to places other than the necessary places and waste is increased. Further, the length B of the comb teeth portion 24 from the tip of the later-described liquid reservoir piece 30 to the upper surface of the housing portion 22 is preferably 15 to 35 mm, and more preferably 20 to 30 mm. If the length is too short, it is difficult to supply the hair dyeing solution to the root of the hair, and if the length is too long, the hair tends to be caught easily and the operation tends to be difficult. The width C of the base end of the comb tooth 24 shown in FIG.
mm, more preferably 7 to 13 mm. If the width is too small, the resistance received from the hair becomes small and it becomes difficult to apply the hair dyeing liquid along the hair, while if the width is too large, the resistance received from the hair becomes large and the operation becomes difficult gradually. Further, it is necessary to consider the type and viscosity of the hair dyeing solution, but the diameter of the discharge port 26 is preferably 0.5 to 3.0 mm, more preferably 1 to 2 mm. If the diameter is too small, the discharge pressure increases and it becomes difficult to discharge the hair dyeing liquid. On the other hand, if the diameter is too large, the hair dyeing liquid may splatter or drip when the container is pressed.

Around each discharge port 26, this discharge port 26
A pair of liquid storage pieces 30, 30 opposed to each other with the. The pair of liquid reservoir pieces 30, 30 are arranged in parallel with the width direction of the comb teeth portion 24, that is, in the direction in which the hair is combed, with the discharge port 26 interposed therebetween, and the hair dye discharged from the discharge port 26. The liquid is held in a liquid storage space 32 formed between the pair of liquid storage pieces 30, 30. As shown in FIG. 2, the liquid reservoir 30 has a tapered side view and an arcuate tip, thereby facilitating uniform application of the held hair dyeing liquid along the hair. ing. Although it is necessary to consider the type, viscosity, and the like of the hair dyeing liquid so as to be able to hold the hair dyeing liquid, the interval between the liquid reservoir pieces 30, 30 is preferably substantially the same as the diameter of the discharge port 26. The length D of the liquid storage piece 30 shown in FIG. 2 in the protruding direction is preferably 1 to 10 mm, more preferably 3 to 6 mm.
The width E of the base end of 0 is preferably 3 to 10 mm,
More preferably, it is 4 to 8 mm. If the area of the side surface of the liquid reservoir 30 is too small, the amount of the hair dye supplied to the root portion of the hair becomes insufficient, while if the area is too large, the amount of the hair dye retained by the liquid reservoir 30 is large. And tend to stain the ground.

The hair dyeing nozzle 1 configured as described above
When the hair dyeing is performed using the method, first, the side wall of the container is pressed, and the hair dyeing liquid in the container is discharged from the discharge port 26 of each comb tooth portion 24. The discharged hair dyeing liquid is held in the liquid storage space 32 at the tip of the comb tooth part 24. Subsequently, hair is repeatedly combed while pressing the side wall of the container to dye the hair.

According to the hair dyeing nozzle 1, even if the container pressing force fluctuates while combing the hair and the hair dyeing liquid is not sufficiently discharged from the discharge port 26, the liquid storage space 3
Since the hair dyeing liquid is held at 2, the hair dyeing liquid can be stably supplied. In other words, the held hair dyeing liquid exerts a buffering action on the fluctuation of the discharge amount from the discharge port, so that it is possible to prevent application unevenness, and it is possible to apply the hair uniformly. Further, since the liquid storage space 32 is formed at the tip of the comb teeth 20, when the tip of the liquid storage piece 30 comes into contact with the scalp, the hair dyeing liquid is sufficiently supplied to the root of the hair. Therefore, the hair dyeing solution can be applied to the entire hair without causing a problem such as the conventional undyed hair.

Next, a hair dyeing nozzle according to a second embodiment of the present invention will be described. FIG. 4 is a partial sectional front view of a hair dyeing cap according to a second embodiment of the present invention, FIG. 5 is a partial sectional side view, and FIG. 6 is a plan view. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The hair dyeing nozzle 1a shown in FIGS.
In the hair dyeing nozzle 1 shown in FIGS. 1 to 3, a liquid dripping preventing piece 40 is further provided in the vicinity of each pair of liquid storing pieces 30, 30. The anti-dripping piece 40 is erected on the upper surface of the housing 22 on one side in the width direction of the liquid storage space 32 (that is, the rear side in the combing direction) so as to be parallel to the liquid storage piece 30. Have been. This dripping prevention piece 4
0 has substantially the same length as the liquid reservoir 30 and the liquid reservoir 3
It has a thickness substantially equal to the interval between 0 and 30,
A gap is formed between the two to allow the combed hair to pass.

According to the hair dyeing nozzle 1a, when the comb teeth 20 are moved upward, for example, when the hair dyeing solution is applied to the alba, the hair dyeing solution held in the liquid storage space 32 is removed. It is received by the dripping prevention piece 40 located below it. Therefore, during the hair dyeing operation, there is no possibility that the held hair dyeing solution drips off, and the usability can be improved.

[0018]

As is apparent from the above description, the hair dyeing cap of the present invention can hold the hair dyeing liquid between a pair of liquid collecting pieces at the tip of the comb tooth portion, so that it can be applied to the hair. Can be applied uniformly, and the hair dyeing solution can be sufficiently supplied also to the root part of the hair, and the undyed hair can be prevented.

When the anti-dripping piece is provided near one side in the width direction of the liquid-storage space formed between the pair of liquid-storing pieces, the dripping-preventing piece causes the dripping of the hair dyeing liquid. Can be prevented.
