Description

【０００１】
【発明の属する技術分野】
本発明は、スプレーノズル、特にスプレーノズルのノズル基台に連設する押圧プレートに関する。
【０００２】
【従来の技術】
スプレーとして、下端にフランジ（６、７）を設けたノズル（ブッシュ要素２）をエアゾールボトル（１）のステム（弁栓４）に取り付け、フランジを押し下げることによってノズル先端の噴出孔から薬液を噴霧するようにしたスプレーは、従来より知られており（例えば特公平６−１３０５３号公報参照）、また、下端に押圧プレート（１９）を設けたノズル部材（吐出接続部材２０）の内筒をポンプのステムに取付け、ノズル部材の押圧プレートを押下げることによってポンプから薬液を吐出し、ノズルの噴出孔から噴霧するようにしたスプレーも知られている（特公平６−６２１６９号公報参照）。
【０００３】
【発明が解決しようとする課題】
しかしながら、フランジ、或いは押圧プレートの押下げ操作にあたって、使用者は斜め押し、すなわちノズル部材の押下げ方向をボトルのステムやポンプの軸線に対して傾斜する方向に押下げる場合がある。
そのときには、上記特公平６−１３０５３号公報記載のスプレーでは、ステム先端とノズルの取付部との間に間隙が生じ、そこから内容物が洩れるという問題があった。
【０００４】
また、後記の特公平６−６２１６９号公報記載のスプレーでは、ノズルの外筒と内筒は、上端で接続されており、押圧力の作用点はノズルの上端部となっているので、斜め押しした場合は、作用点がステムの軸線から大きく外れ、内筒とポンプのステムとの間に大きなモーメントがかかり、ポンプのステム、ピストン部材を傾斜させるように作用し、上下動にあたって、ピストン部材がスムーズに上下動できなくなるという問題があった。
【０００５】
本発明は、上記の問題点を解決することを課題とし、ノズル部材の連結筒の下端部に押圧プレートを連設し、連結筒とポンプのステムとの間に、大きなモーメントがかからないようにしたノズル部材を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は、上記の課題を解決するため、スプレーノズルとして、ポンプを装着した取付キャップと、ポンプのステムに取着されたノズル部材とからなるスプレーノズルであって、ノズル部材は、ノズル基台と、ノズル基台に取着され、ノズルヘッドを具えたノズル本体とを具えており、ノズル基台に、ポンプのステムへの係合部に近接して押圧プレートが連設されていることを特徴とする構成を採用する。
【０００７】

ピストン部材Ｂ２のピストン部は、シリンダーＢ１内に内蔵されており、ポンプＢの内部構造は、ノズル部材Ｃの操作に応じて容器ＡＯ　の薬用液を吸上げ、ノズルから噴霧できるものであればよく、従来公知のものであるので説明を省略する。
シリンダーＢ１の上方には、ピストン部材Ｂ２のステム１２が突出している。
【００１１】
図１，２に示すように、ノズル部材Ｃは、ノズル基台２０と、該ノズル基台２０の先端に装着されたノズル本体２１とからなっている。

【００１２】
連結筒２２の内部は流通路２６となっており、連結筒２２の上端部外周は、縮径されて係合筒部２７となっている。
係合筒部２７の上端には、流通孔２８が穿孔され、その上方にはヘッド内筒２３が続いている。
【００１３】
ヘッド内筒２３は、頂壁２９と側周壁３０とからなっており、側周壁３０には、流通孔２８に続く通路３１が設けられている。
【００１４】
連結筒２２の嵌合部２５の上方には、連結環３２が連設され、該連結環３２の外周縁から筒壁３３が垂設されている。
筒壁３３の下端には、押圧プレート３４が連設され、押圧プレート３４の下面には、案内筒３５が垂設されている。
連結環３２、筒壁３３、押圧プレート３４によって押圧部材２４が構成されている。
【００１５】
押圧プレート３４の上下方向での位置は、連結筒２２とポンプＢのステム１２との係合部と等しい位置、或いは近接した位置としている。

【００１６】
ノズル本体２１は、ノズルヘッド４０と、該ノズルヘッド４０の外周縁に沿って垂下するノズル筒４１とからなっている。
ノズルヘッド４０は、頂壁４２と側壁４３とを具え、頂壁４２の中央には、噴霧孔４４が穿孔されており、ノズル基台２０の嵌合筒部２７に嵌合される取付筒４５が垂設されている。
【００１７】
ノズルヘッド４０をノズル基台２０に取着したときには、ノズルヘッド４０とヘッド内筒２３のそれぞれの頂壁４２と頂壁２９の間隙、および側壁４３内周と側周壁３０との間隙によって流路４６が形成され、連結筒２２の流通路２６、流通孔２８、流通路３１に続く噴出流路が構成される。

また、ノズル本体２１と押圧プレート３４の色彩を変えることによって加飾の異なるスプレーを得ることができる。
【００２５】
前記実施形態では、ノズル本体２１のノズル筒４１を押圧部材２４の筒壁３３に嵌合するようにしたが、筒壁３３の外周と、ノズル筒４１下部内周にねじを螺設して螺合させるようにしてもよい。
【００２６】

【００２７】
【発明の効果】
本発明は、上記のように構成されているから、次の効果を奏する。
ノズル基台に、ポンプのステムへの係合部に近接して押圧プレートを連接したから、斜め押ししてもノズル基台にかかる押圧力の作用点がステムの軸線からわずかしか偏寄しないようになり、ステムにかかるモーメントが少なくなるので、ピストン部材は、常にスムーズに上下動させることができる。
