(57) [Problem] To provide a compressed gas aerosol push button capable of spraying an aerosol content over a wide range and a high-quality aerosol content having a high crushing effect. SOLUTION: The diameter of an injection port 12 of a push button 1 is 0.22-0. 28 mm and a length of 0.1 to 0.3 mm. The conical swirl chamber 14 inside the injection port 12 has a diameter of 0.15 to 0.35 mm on the side connected to the injection port 12 and a diameter of 1.0 to 2.0 mm on the side of the content inflow portion. Two injection grooves 17 tangentially connected to the swirl chamber 14 are formed in the swirl chamber 1. 4, the groove width of the connecting portion 18 is 0.15 to 0.35 mm, the groove width of the outer peripheral end is 0.4 to 0.8 mm, and the groove depth is 0.1. ０．３0.3 mm. The inflow portion 5 of the aerosol content is connected to the injection groove 17, and the injection port 12 is Make it more injectable. |
