PURPOSE:To easily adjust a jetting amount of jet-out fluid from a jetting port while jetting the jet-out fluid by a method wherein a jetting amount adjusting device operable and adjustable from behind is disposed at the midway of a jet-out fluid flow path. CONSTITUTION:A jetting head structure of an aerosol package is provided with an inflow port 1 for allowing jet-out fluid to flow in from downward and a jetting amount adjusting device 3 for adjusting an open degree of an open part of a jet-out fluid jetting port 2 provided on the upper front end of the jetting head structure. The jetting amount adjusting device 3 is provided with a rotating operation part 4 disposed behind the jetting head structure. In the rotating operation part 4, a sealing material 5, such as an O ring, is fitted in the middle part thereof, and a top part is formed into a needle valve 6 for finely adjusting the open area of the jetting port 2. By operating the needle valve 6 forward and backward through a helical part 7, a jetting amount is adjusted. |
