And the pressure inside the container is 4.9 kg / cm 2 , and the central portion of the upper end formed on the injection nozzle has a narrow flat portion 43 so that its length direction is perpendicular to the user. While visually observing, the entire amount was jetted by placing it on the floor surface of a large closed space. At the time of operation, the user did not spray any spray. The injection status of the contents is shown by solid lines in FIGS. Note that FIG.

The nozzle nozzle used had three nozzle holes (openings), and the openings had the same area and the total area along the slope was 0.42 mm 2.
And In addition, the conduction path (second of the nozzle injection port used in the embodiment)
(Corresponding to the communication hole) of 1.28 mm 2 . The spray area spreads in all directions, but is narrower than in the case of Example 1, and it is difficult to avoid partial spraying of the spray agent to the user side at the start of spraying because the spray ports are on three sides.

The openings have substantially equal areas, and the total area is 0.42 mm 2 . Since the nozzle hole is facing upward, the spray agent was not directly sprayed to the user,
The spray area was small. The injection state is shown by a two-dot chain line in FIGS.

From this, it can be seen that the spraying state is also diffused in the 180 ° direction, and the user side is not sprayed at all. Therefore, the superiority of the pest removal method using the full-quantity injection type aerosol device according to the present invention is clear.

る。 EFFECT OF THE INVENTION According to the method for removing pests using the total-injection-type aerosol device according to the present invention, the active ingredient is broadened by arranging the injection nozzle at the center of the room where the pests need to be removed. The range can be sprayed. At that time, the spray direction is limited to two directions separated by 180 ° and the user can easily perceive the spray direction at the start of the operation, so that the propellant is sprayed toward the user. Can be reliably prevented, and as a result, the full-volume injection type aerosol device can be easily handled. In addition, the momentum of the content injection is higher than that of the conventional injection nozzle.
As a result, the diffusion is improved and the density is increased.
Can effectively control pests in a closed room
