- water is used as a one-time-use type pesticide that sprays the entire amount of the drug in the room, including a smoke type that burns and uses the pesticide composition.
- Various types are known, including those that do not use fire, such as a heat transpiration type, an aerosol type sprayed with a propellant, and a pump type that sprays a solution with a pump.
- a smoking type insecticide is a combination of an insecticidal component, an exothermic agent, and an auxiliary heat agent placed in a container. When ignited with a starter, insecticidal components and burning agents burn. At that time, the finer particles of the insecticidal component spread as smoke in the room (see Patent Document 1).

Abstract
Description
加熱蒸散タイプの殺虫剤は、水と酸化カルシウムなどの反応熱により加熱された容器から発泡剤の力により殺虫成分を拡散させる(特許文献2参照)。
エアゾールタイプの殺虫剤は、殺虫成分をLPガスなどの液化ガスに溶解して、耐圧容器に圧縮充填したもので、殺虫成分は細かい霧になって噴出する。一回使い切りタイプでは押しボタンに不可逆的なロックがかかり、薬剤の全量が噴射される構造となっている(特許文献3参照)。
ポンプタイプの殺虫剤は、殺虫成分を溶媒に溶解して液体容器に収納したもので、液体容器に接続された圧送ポンプの作用により、殺虫成分は細かい霧になって噴出する(特許文献4参照)。
更に、これらのタイプの殺虫剤は、燃焼剤が燃えたり、発泡剤が分解したりした際に、殺虫成分とは別の溶媒や分解ガス(酸性ガス)、液化ガス等の媒体が部屋内に散布される。そこで、使用時には、パソコンやオーディオ機器等の精密機器にカバーをかけたり、火災報知器に覆いをしたり、ガス湯沸かし器の種火を消したりするなどの事前準備が必要であった。

従って、従来のように薬剤の燃焼によりくん煙剤を発煙させたり、発泡剤を間接的に加熱する加水発熱剤を用いて薬剤を加熱蒸散させたりする必要がない。その結果、粉状薬剤には熱が加わらず、熱に弱い薬剤を使用することができる。また、エアゾールタイプやポンプタイプのように薬剤を溶媒や液化ガスに溶かす必要もなく、溶解性の低い薬剤や、溶液状態で不安定な薬剤を使用することもできる。
また、保存時には、粉状薬剤は両端がそれぞれ封止フィルムで封止された筒状体に密封されているため、取扱いが容易である。またさらに、筒状体の中の粉状薬剤が外気の水分や酸化により分解されることを防ぐこともでき、安定に保存することができる。
従って、従来のくん煙タイプや加熱蒸散タイプのように、燃焼剤や発熱体の熱でくん煙剤を発煙させたり、発泡剤を加熱し、発泡剤が分解する際に発生する分解ガスを利用することで粉状薬剤を蒸散させたりする必要がない。その結果、粉状薬剤には熱が加わらず、熱に弱い薬剤を使用することもできる。また、従来のエアゾールタイプやポンプタイプのように薬剤を溶媒や液化ガスに溶かす必要もなく、溶解性の低い薬剤や、液体状態で不安定な薬剤を使用することもできる。
また、保存時には、粉状薬剤は両端を封止した筒状体に密封されることで、取扱いが容易となる。またさらに、筒状体の中の粉状薬剤が外気の水分や酸化により分解されることを防ぐこともでき、安定に保存することができる。なお、使用時には、筒状体における容器本体の外部側の他端部を封止している封止フィルムや封止部材を予め取り除いても良い。
さらに、本発明の粉状薬剤噴射装置および粉状薬剤噴射方法は固定電源や火熱などを使う必要がないため、火事などの恐れがなく安全であり、大規模な装置も不要なため、簡便に持ち運ぶことができ、電源などの設備のない場所でも使用する事ができる。
図1に示すように、本実施形態の粉状薬剤噴射装置1は、上端開口部13を有し、水(液体)51を収容する容器本体11と、上端開口部13を塞ぐ蓋体21に装着され、両開口端が容器本体11の内部と外部に臨む筒体23と、筒体23内に装入された粉状薬剤30と、粉状薬剤30が装入された筒体23の両開口端をそれぞれ封止し、所定以上の圧力が作用すると破断する一対の封止フィルム25,27と、容器本体11内に投入され、容器本体11内の水51と反応して反応ガスを発生するガス発生剤である重曹41及びクエン酸43と、を備える。
筒体23内には粉状薬剤30が収納されており、両開口端がそれぞれ一対の封止フィルム25,27で封止されている。封止フィルム25,27としては、例えばパラフィルム(商品名:パラフィルムM、型番:PM996、Pechiney Plastic Packaging社製)を用いることができる。封止フィルム25,27は、例えば床面積約9m2の居室に粉状薬剤を噴射するためには80~100kPa程度の所定以上の圧力が作用すると破断することができるものであれば、パラフィルムに限らず種々のフィルムを用いることができる。また、使用するフィルムが延伸可能であれば延伸の有無に限らず、用いることができる。また、延伸できないフィルムであっても同様に用いることができる。
また、水を保持させた吸水性ポリマーを容器本体11内に予め所定量収容してもよい。
なお、重曹41とクエン酸43からなるガス発生剤をフィルムなどに封入し、筒体23の下部に予めセットしておき、使用時に何らかの開封機構を利用してフィルムを開封することで、ガス発生剤を水51中に投入してもよい。
そして、図2の(d)に示すように、容器本体11内の炭酸ガスのガス圧が、例えば封止フィルムとしてパラフィルムを延伸させずに用いた場合、80~100kPa、さらにこれ以上となると、筒体23の両開口端を封止している封止フィルム25,27が破断されて、容器本体11内の高圧の炭酸ガスの風圧で粉状薬剤30が筒体23外へ一気に噴射拡散される。
上述した本実施形態の粉状薬剤噴射装置1および粉状薬剤噴射方法によれば、ガスや溶媒等の媒体を用いることなく、薬剤としての殺虫剤を拡散することができる。
ポンプ式噴霧装置210は、薬液(薬剤)Mを収容する液体容器211と、薬液Mを噴霧する噴霧ユニット220と、噴霧ユニット220に圧縮空気を供給する圧送ポンプであるエアポンプ212と、を備える。
また、ニードルホルダ221の大径孔221a側の端部には、樹脂製の吸液チューブ226が気密に外嵌されている。この吸液チューブ226は、ニードルホルダ221が蓋体214に固定された状態において、その先端が容器本体213の底面近傍に位置する長さに調節される。
ポンプ式噴霧装置210は、図7に示すように、薬液Mが収容された容器本体213に噴霧ユニット220と一体化された蓋体214を螺着させ、噴霧ユニット220とエアポンプ212とを接続チューブ217で接続させて、モータ部215に電力を供給してエアポンプ212を駆動させることによって、圧縮空気発生部216の吐出口216bから圧縮空気を吐出させる。
このとき、ノズル孔224の上端開口224aとニードル管225の開口225aとの間に負圧が発生するため、液体容器211内の薬液Mが、吸液チューブ226、ニードルホルダ221の大径孔221a、及びニードル管225を介して吸い上げられ、ニードル管225の開口225aから吐出されて、上記の勢いよく噴出される圧縮空気によって霧化して噴霧される。
加熱蒸散装置310は、有底円筒状の外容器313と、この外容器313の内部に仕切部材314により区画形成された薬剤収納部315とで構成される熱発生装置317を備える。
加水発熱剤321は、外容器313の周壁、仕切部材314及び不織布シート327とで形成される空間に充填されている。仕切部材314の内部に区画形成された薬剤収納部315には、発泡剤と殺虫成分を含む薬剤(加熱蒸散用製剤)320が収容されている。
また、熱溶融フィルム322は加水発熱剤321からの放熱、外容器313の熱並びに蒸散した薬剤320との接触により熱溶融するため、蒸散の比較的早い時期から、蒸散した薬剤320は蓋部材319の開口部を通じて効率良く外部に放出される。

薬剤そのものか、粉体に薬剤を含浸あるいは混合させた粉状薬剤30が収納され、両端における少なくとも前記容器本体の内部側を封止フィルム25,27で封止された筒体23が装着された蓋体21を、前記容器本体11の内部と外部に前記筒体の両端が臨むように前記上端開口部13に装着する工程と、
所定以上となった前記反応ガスのガス圧で前記封止フィルム25,27を破断することにより、前記筒体23に収納された前記粉状薬剤30を噴射拡散させる工程と、
を有する粉状薬剤噴射方法。
上記実施形態の粉状薬剤噴射装置1において、封止フィルム27で封止された筒体23の上部開口端が鉛直方向上向きとされ、封止フィルム25で封止された筒体23の下部開口端が鉛直方向下向きとされているが、筒体23の両開口端の向きは、斜め上方向きや水平向きなど、種々の向きを採りうることは勿論である。
またさらに、筒体23における容器本体11の外部側の他端部に縮径のノズルを設けたり、筒体23を容器本体11の外部側の他端部に向かって縮径するように形成して筒体23自体をノズル形状としたりしてもよい。筒体23にノズルを設けることで噴射時の風速が高まり、より遠くまで粉状薬剤30を拡散させることができる。
(実施例1)
まず、本発明に係る粉状薬剤噴射装置1の噴射効果を確認するため、粉状薬剤噴射装置1を用いたd・d-T-シフェノトリン(商品名:ゴキラートS、住友化学株式会社製)、ジノテフラン(商品名:スタークル、三井化学アグロ株式会社製)の床面への薬剤落下量測定試験を行った。実施例1の粉状薬剤噴射装置1では、封止フィルム25,27の破断強度は100kPaとした。なお試験毎での破断時のガス圧力にずれが生じないように、ローリングポンプの圧縮空気を用い、封止フィルム25,27への加圧を100kPaに揃えて試験を行った。その試験内容について以下に示す。
(試験方法)
1.縦470cm×横540cmの室内に、図3に示した床面積約9m2(縦270cm×横340cm×高さ15cm)の試験区を設定した。試験区床面100の中央にローリングポンプPに直接接続された筒体23を設置し、粉状薬剤噴射装置1からそれぞれ両側に50cm、100cm、150cm離れた複数のシャーレ設置位置(a)~(f)に金属製シャーレを設置し、斜向かいに200cm離れたシャーレ設置位置(g)、(h)に金属製シャーレを設置する。金属シャーレはそれぞれのシャーレ設置位置(a)~(h)に4枚ずつ設置し、4枚の中心部が粉状薬剤噴射装置1からの距離が50cm、100cm、150cm、200cmとなるように設置した。
2.ローリングポンプPの吐出口が筒体23に直接接続された粉状薬剤噴射装置1により4種の粉状薬剤30を噴射し、1.5時間後にシャーレ設置位置(a)~(h)の金属シャーレを回収する。尚、試験毎に100kPaの圧力で封止フィルム25,27が破断していることを確認するため、ローリングポンプPの吐出口と筒体23の間に圧力ゲージGを設置した。
3.回収した各シャーレ設置位置(a)~(h)の金属シャーレ内より4種の粉状薬剤30における、d・d-T-シフェノトリン、ジノテフラン量を分析する。
4.分析結果に基づき、d・d-T-シフェノトリン、ジノテフランそれぞれの単位面積当りの薬剤落下量(mg/m2)を算出する。
それぞれ複数回行った上記床面への薬剤落下量測定試験による結果を下記表1~4に示す。
1.粉状薬剤噴射装置
筒体23にポンプ(応研精工株式会社製のローリングポンプ 型番:P30C02R8516、M42C02R8516を2台連結)Pの吐出口を直接接続したもの。
筒体23:内径7mm、長さ50mmのアクリルパイプ
封止フィルム25:パラフィルム(商品名:パラフィルムM、4インチ×125フィート)
封止フィルム27:パラフィルム(商品名:パラフィルムM、4インチ×125フィート)
筒体23の両端部にパラフィルムを巻き付け、封止フィルム25,27とした。封止フィルム25,27の強度を測る為、筒体23とポンプPの間に圧力ゲージGを設置し、ポンプ(応研精工株式会社製のローリングポンプ 型番:P30C02R8516、M42C02R8516を2台連結したもの)Pの圧縮空気で加圧して、封止フィルム25,27が破断する際の圧力を測定した。
パラフィルムを延伸させずに巻き付け、封止フィルム25,27が破断する際の圧力が100kPaとなるように調節した。
2.粉状薬剤30
(薬剤A) アセトンに溶解させた18mgのd・d-T-シフェノトリン(商品名:ゴキラートS)を36mgのケイ酸カルシウム(商品名:フローライトRN)に含浸させた後、風乾にてアセトンを除去し、総量54mgとした(ケイ酸カルシウム:d・d-T-シフェノトリン=2:1)
(薬剤B) 18mgのジノテフラン原末(商品名:スタークル)
(薬剤C) ジノテフラン18mgを162mgのでん粉粉末(商品名:アミコールH)と混合させ、総量180mgとした(でん粉粉末:ジノテフラン=9:1)
(薬剤D) アセトンに溶解させたジノテフラン(商品名:スタークル)18mgを36mgのケイ酸カルシウム(商品名:フローライトRN)に含浸させた後、風乾にてアセトンを除去し、総量を54mgとした(ケイ酸カルシウム:ジノテフラン2:1)
3.シャーレ位置(a)~(h)
面積:254.4cm2(63.6cm2/金属シャーレ)
1.d・d-T-シフェノトリンの薬剤落下量
ジノテフランの分析値が低いのは、ジノテフランが嵩高い粉体であるため、噴射1.5時間後でも空中に浮遊している薬剤量が多いことが原因と推測される。一方、ケイ酸カルシウムに含浸させたd・d-T-シフェノトリンは粘稠な液体であることから、粉状薬剤の密度が増加し、粉状薬剤噴射装置1から200cmの範囲全体にわたり、落下したと考えられる。
次に、本発明に係る粉状薬剤噴射装置1を用いた害虫防除効果を確認するため、殺虫効力試験を行った。殺虫原体としてジノテフラン及びd・d-T-シフェノトリンを用いた効力試験を行った。その試験内容について以下に示す。
(試験方法)
1.縦470cm×横540cmの室内に、図5に示した床面積約9m2(縦270cm×横340cm×高さ15cm)の試験区を設定した。試験区床面100の中央にポンプPに筒体23が直接接続された粉状薬剤噴射装置1を設置し、試験区床面100の一方(図5中、下方)寄りにそれぞれ流しシンクおよび冷蔵庫と床との間の隙間を模したダンボール箱(A),(B),(C)を配置し、試験区床面100の他方(図5中、上方)寄りに餌101および水103を配置する。

(供試頭数、ジノテフラン:雌49頭、雄48頭、d・d-T-シフェノトリン:雌50頭、雄49頭)
