The spray button for the aerosol container is composed of the nozzle 10 having a flow path therein to fit into a valve system 3 at the lower end and the spray port 13a located at a peripheral surface of the nozzle and communicating with the flow path and the cap-shaped button 30 configured as the separated body and operated by downward pressing on its upper surface. The button 30 is mounted on the nozzle 10 to form closed spaces 36, 37 around the nozzle, and the opening 31 to face the spray port 13a located inside the button is formed on a peripheral surface of the button. The shape of the closed spaces 36, 37 is formed to be resonant with spraying sound. <P>COPYRIGHT: (C)2004,JPO |
