【０００２】
【従来の技術】
エアゾール式噴霧器は、胴部の頂壁中央部を貫設させて噴出用ステムを上方付勢状態で起立し、かつ該噴出用ステム上部へノズル孔付きの押下げヘッドを嵌合させたものが一般で、押下げヘッドを押し下げるとノズル孔から霧状物等が噴出するようになっている。
【０００３】
【発明が解決しようとする課題】
上記のようなエアゾール式噴霧器では、片手で缶を握って噴霧操作を行う場合に、一本の指、通常は人指し指で押下げヘッドを押し下げるが、一般に指による押下げ操作は引っ張り操作に比較してそれほど容易ではなく、しかも、このような不利な操作で上方付勢の押下げヘッドを、ある時間継続して複数回押し下げなければならないため噴霧操作がさらにしにくいものとなっていた。
【０００４】

【発明の実施の形態】
以下、本発明に係るエアゾール式噴霧器の実施形態を図面を参照しながら説明する。
図１ないし図５は第１の実施形態を示す。
１はエアゾール缶で、胴部２の上端部に環状突条３を周設すると共に、胴部上端面を閉塞する頂壁４の外周部を環状突条３外面へ巻き締め、かつ頂壁中央部を貫設させて噴出用ステム５を上方付勢状態で起立する。
【００１０】
１０は基部材で、環状突条３外面へ嵌着させた周壁１１上端から内向きフランジ１２を介して四角形状の保護筒１３を起立する。
【００１１】
２０はトリガー付き噴霧部材で、噴出用ステム５の上部外面へ下端部を嵌合させたステム嵌合筒２１上端部から射出筒２２を前方突設し、かつ該射出筒前部下面からトリガー２５を垂設する。さらに、ステム嵌合筒２１の後方下部を板バネ２３を介して保護筒１３の後部上端へ連結する。
なお、２６は射出筒２２前端部内面へ嵌合させたノズルである。
【００１２】
３０はカバー部材で、射出筒２２上面へ載置した頂板３１の左右両部から垂設する左右両側板３２下端部を保護筒１３の左右両側面へ嵌合させる。また、左右両側板３２の後部と連続させて頂板３１後部から垂設する後板３３を薄肉ヒンジ３４を介して周壁１１後部上端へ連結する。
さらに、請求項２記載のように、内向きフランジ１２の左右両部に、保護筒１３へ隣接させて開口部１４を穿設すると共に、左右両側板３２下端から係合爪３５を垂下して、両係合爪を両開口部の左右方向外縁側下面へ係合させる。
なお、後板３３上部は後方へ湾曲する円弧状部３３ａに形成する。
【００１３】
さらに、頂板３１中間部に開口部３６を穿設すると共に、射出筒２２中間部上面から破断可能な破断片２４ａを介して開口部３６上方へ棒部２４を起立して、該棒部上端から一対の弾性片２４ｂを前後方向へ下斜め外方に拡開し、かつこれら弾性片下端を開口部上面へ係合させる。
弾性片の数は２つに限らずそれ以上でもよく、この場合には前後および左右方向へ拡開させる。
なお、基部材１０とトリガー付き噴霧部材２０とカバー部材３０とは合成樹脂材で一体成形する。
【００１４】
次に本実施形態の作用について説明する。
図３および図４はカバー部材３０の組付け前の状態を示すもので、組付けるにはカバー部材３０を上方へ持ち上げて、左右両側板３２を保護筒１３の左右両側面へ嵌合させると共に、開口部３６を弾性片２４ｂへ押し付ける。これにより弾性片が内方へ弾性変形して開口部３６が弾性片２４ｂを通過する。すると弾性片が外方へ拡開して開口部３６上面へ係合する。これと同時に係合爪３５も開口部１４下面へ係合する。
【００１５】
射出筒２２から霧状物等を噴出させるに際し、トリガー２５に軽い力を加えただけでは、弾性片２４ｂが開口部３６上面へ係合しているためトリガーを後方へ引き寄せることはできない。噴出させるにはトリガーを強く引けばよく、すると図５に示すように、ステム嵌合筒２１が噴出用ステム５の上方付勢力と板バネ２３との弾性力に抗して下降し、これと共に射出筒２２も頂板３１から下方へ離間して破断片３４を破断させる。
噴出後、トリガー２５を解放すると、噴出用ステム２１の上方付勢力と板バネ２３の弾性力とによりステム嵌合筒２１が上昇し、これと共に射出筒２２も元の位置に復帰する。
【００１６】
図６ないし図１０は第２の実施形態を示す。
第１の実施形態では、射出筒２２上面から破断片２４ａを介して棒部２４を起立し、該棒部上端から弾性片２４ｂを拡開させて、該弾性片下端を開口部３６上面へ係合させるが、本実施形態では、これらを設ける代わりに、保護筒１３前部とトリガー２５下方後部との間に四角形状の板状スペーサ４０を介在させ、該スペーサと保護筒とを、またスペーサとトリガーとをそれぞれ破断用連結片４１で連結させる。なお、破断用連結片はスペーサ前部下端と周壁１１前部との間に追加して設けてもよい。
【００１７】
また、第１実施形態では、係合爪３５を開口部１４に係合させるが、本実施形態では、これに代えて請求項４記載のように、カバー部材の左右両側板３２の下端部内面に第１嵌合爪４２を、かつ保護筒１３の左右両面上端部に第２嵌合爪４３を、それぞれ形成して、第１嵌合爪を第２嵌合爪へ嵌合させる。
その他の構成は第１実施形態と同様であるから説明を省略する。
【００１８】
本実施形態において、胴部内の内容物を噴出させるには、スペーサ４０を左右どちらかの方向へ引っ張って破断用連結片４１を破断させることによりスペーサを除去すればよい。
【００１９】
【発明の効果】
請求項１および３記載の発明は、トリガーを後方へ引き寄せることで射出筒から霧状物等を噴出させることができ、従って、従来の押し下げ操作による場合に比較して片手による噴霧操作が容易になる。
また、請求項１記載の発明では弾性片を開口部へ係合させ、請求項３記載の発明ではスペーサを設けたので、それぞれ流通経路におけるトリガー引寄せ防止が図れると共に、トリガー引寄せによる使用の事実が視認可能になる。
【００２０】
請求項２記載の発明では係合爪を開口部に係合させ、また、請求項４記載の発明では凹凸の嵌合手段を設けたので、カバー部材の基部材に対する取付けがより強固になる。
