PROBLEM TO BE SOLVED: To provide a spray device for controlling a pest insect, capable of controlling the pest insect such as a mosquito always well without using an electric source such as a battery at all.SOLUTION: The spray device for controlling the pest insect is equipped with a pressure-resistant container 8 for storing chemicals having pest insect-controlling effects, having a valve stem 12 installed in the upper part, and stored in the interior of a device body 1, a button 15 for spraying, moving upper or lower and installed in the upper part of the device body 1, and a malfunction-preventing mechanism part 30 capable of fixing the downward movement of the button 15 for spraying. The spray device is constituted so that the chemicals may be sprayed from a discharging opening 11 of the valve stem 12 so as to sustain the pest insect-controlling effects over a long period when the button 15 for spraying is pushed and moved downward to allow the valve stem 12 of the pressure-resistant container 8 stored in the interior of the device body 1 to be pushed. The downward movement of the button 15 for spraying is fixed by the malfunction-preventing mechanism part 30 to prevent the valve stem 12 of the pressure-resistant container 8 from being pushed.COPYRIGHT: (C)2010,JPO&INPIT【課題】電池等の電源を一切用いることなく、常に良好に蚊等の害虫を駆除することができる害虫駆除用噴霧装置を提供する。【解決手段】上部にバルブステム12を設けた害虫駆除効果を有する薬剤を収容する耐圧容器8を、装置本体1の内部に収納し、この装置本体1の上部に、上下動する噴霧用ボタン15を備え、この噴霧用ボタン15を押して下方に移動させることにより、装置本体1の内部に収納した耐圧容器8のバルブステム12も押されて、このバルブステム12の放出口11から薬剤が、害虫駆除効果が長時間にわたって持続するように放出されると共に、この噴霧用ボタン15の下方への移動を固定可能とする誤作動防止機構部30を備え、この誤作動防止機構部30によって、噴霧用ボタン15の下方への移動を固定して、耐圧容器8のバルブステム12が押されないようにした害虫駆除用噴霧装置である。【選択図】図4
