Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. 61-190230, there has been one in which an aerosol container equipped with an application part having a brush is filled with hair cosmetics. Since these hair cosmetics can be easily applied,
It has been widely used in hair coloring and hair care.

[0003]

However, the conventional hair color applicator has a drawback that it requires a certain amount of skill to apply it evenly to the hair and to dye the hair without dyeing the scalp. It was Further, there is a drawback that the hair dye drips during use and contaminates the skin and clothes.

[0004]

Means for Solving the Problems In the hair dyeing tool in which a comb portion is attached to an aerosol container containing a hair dye, the present inventors have provided an L-shaped pipe communicating with a jet nozzle. With a simple structure, it can be applied evenly to the hair, and it can be dyed without dyeing the scalp, and it does not drips during use and contaminates the skin or clothes, and it does not stain the hands or fingers easily. A usable hair dyeing tool has been completed.

With the hair dyeing tool of the present invention, the hair dye filled in the aerosol container is discharged to the discharge passage through the jet nozzle and the L-shaped pipe by the pressure of the propellant. By using the L-shaped pipe to supply the hair dye from the ejection nozzle to the comb portion, the push button can be provided on the upper portion of the ejection nozzle, and the structure can be easily applied. The L-shaped pipe moves up and down in conjunction with the up and down operation of the push button. The material may be metal such as stainless steel or synthetic resin having a certain degree of hardness.
