ABSTRACT:
The present invention is intended to provide a dispenser structure for aerosol containers, which can control the discharge rate of aerosol and ensure satisfactory and safe dispensing of the aerosol while preventing the particle size of the dispensed aerosol from becoming too fine and preventing its excessive scattering which too fine particles would entail. Its structure is characterized in that it includes a dispenser (1) provided with a dispensing guide or first nozzle (11) communicating with a dispensing valve (2); a second nozzle (10) provided within the dispensing guide or first nozzle (11) and having a smaller dispensing port (10a) whose bore d is not more than 0.5 mm; and a larger dispensing port (1a) having a bore b of 0.8 to 3 mm and a length c of not less than 5 mm, formed within the dispensing guide or first nozzle (11) downstream, in the direction of dispensing from the second nozzle (10).
