To improve the quick acting property and the persistence of an active ingredient in a mixed liquid by providing a spray vessel with nozzle containing the mixed liquid composed of a pressurizing agent and the active ingredient and a storage chamber for intermittently storing the active ingredient, spraying the mixed liquid by the external force applied to the storage chamber and volatilizing a part of the spray liquid.
The storage chamber 3 is installed in the spray vessel by engaging a hollow system 4 provided in the storage chamber 3 with a nozzle 1 having a spray port 2 at the tip part. The spray vessel is provided with a tilt type valve or a push down type valve and the mixed liquid is spayed from the spray vessel by working the valve. The mixed liquid sprayed from the spray port 2 is scattered from a volatilizing outlet 5 provided on the extension line of the nozzle 1 and not a few parts of mixed liquid strike against the inside surface of the storage chamber 3 to be stored in the storage chamber 3. The accumulated mixed liquid is gradually volatilized. A porous body can be provided in the storage chamber 3 to intermittently store a part of the sprayed mixed liquid.
