Abstract

PROBLEM TO BE SOLVED: To start the spray of an insecticide after a predetermined time is elapsed after setting by engaging the press lever biased by an elastic member so as to be revolved toward a nozzle by the press plate brought into contact with a water absorbable softening porous member. SOLUTION: When water is fed into an injection recessed part at a time of the use of a container 1, water passed through a cut groove 27 through a through-hole 38 to be absorbed by a porous member 5. The porous member 5 is softened by water absorption and a pressure plate 8 presses the porous member 5 by the elastic restoring force of a torsion spring 7a to advance while compresses the same and a press lever 6 is revolved by this operation to press and tilt a spray nozzle 4. As a result, the stem of the nozzle 4 is tilted to spray the insecticide in the container 3 from the tip of the spray nozzle through the stem. The time up to the tilting of the stem after spray is set to the time required until a spray setting person comes out of a hermetically closed chamber, for example, about 5-30sec and adjusted by the size of the porous member 5, that of the through-hole 38 or the width of the cut groove 27.
