Abstract
A push button for powder aerosol has a push button body, a nozzle and a guide passage. The nozzle is formed in the push button body with a diameter in a range of 0.4 mm to 1.0 mm and a length in a range of 0.3 mm to 2.0 mm in communication with a stem of an aerosol container. The guide passage is formed in the push button body in continuation with an outer end of the nozzle in extending in a spraying direction of the nozzle and formed with a diameter of a range of 1.0 mm to 3.0 mm that is larger than the diameter of the nozzle and a length of a range of 3.0 mm to 20.0 mm for guiding the contents of the powder aerosol. The nozzle flows out the contents with diffusion suppressed, so that accurate application can be made to the limited range on aimed areas such as skins.
