ABSTRACT:
A subdivided fixed amount distributing apparatus for aerosol containers is provided in which aerosol contents exceeding a specified amount is prevented from being used in one cycle by keeping constant in total number of injection times at all times. A structure is simplified by making it possible to eject total amount to the outside every one time by means of a fixed amount injection valve, so that damage to the distributing apparatus due to outside air temperature is prevented and movement of the distributing apparatus is made smooth when it is pushed and released. The subdivided fixed amount distributing apparatus includes a lower sleeve18secured to an upper end of an aerosol container1, a nozzle body15formed with a nozzle16communicating with a stem4, a rotating body23disposed in a rotatable manner with respect to the nozzle body15and the lower sleeve18, an annular body34disposed at an upper side of the rotating body23, a pushing body45pushing the stem4, and an upper sleeve37secured to the lower sleeve18at a lower end thereof, in which pushing operation of the stem4enables a fixed amount injection of the aerosol contents and positional movement of a fitting piece28while pushing operation of the stem4and positional movement in the same direction of the fitting piece28are disabled by hitting the fitting piece28on an upper end surface of a lower projection21after positional movement by pushing operation of predetermined times.
