Description

【０００１】
【発明の属する技術分野】
本発明は液体噴出容器に関する。
【０００２】
【従来の技術】
液体噴出器として、図３に示す如く、容器体１からステム２を介して上下動自在に上方付勢状態で突出された噴出ヘッド３を押し下げることにより、容器体内の液体が噴出ヘッドの前面から突出されたノズル筒４より噴出するように設けたものが知られている。
またこの噴出器は、噴出ヘッド下部に口栓付き部材５を装着させてノズル筒４先端からの液の漏出防止、或いはノズル内の液の固化の防止等を図る様に構成されている。
この口栓付き部材５は、噴出ヘッド下面に、その下面のステム接続部を囲繞して形成された環状凹部６内へ、リング状部７を嵌合させ、リング状部７の前部外面から突出させた弾性片８前端をノズル筒前端近傍まで延出させ、かつ弾性片前端に付設させた口栓９をノズル筒の前端開口部へ着脱自在に嵌合させて形成している。
【０００３】
【発明が解決しようとする課題】
上記従来の噴出器では、不使用時には口栓９でノズル筒開口部を閉塞しているため、ノズル筒内の乾燥を防止し、ノズル筒内の残液が固化する等の不都合を防止できるものである。
しかしながら、この噴出器は、その口栓付き部材を上記した如く装着しているため、組み付け操作が比較的面倒であり、また、誤って噴出ヘッドを押し下げた場合には口栓を押し出して液の漏出をおこす虞があった。また、噴出器使用時に口栓がノズル筒開口部近傍に位置して注出の邪魔となる虞があり、指等で弾性片８を押さえれば解決するが、液注出操作が面倒となる。
【０００４】
本発明は、上記した点に鑑み、ノズル筒内の乾燥を防止してノズル筒内の残液が固化する等の不都合を防止できるとともに、不用意な液の漏出を防止することができ、しかも、液の注出等の取り扱い操作も簡単な優れた液体噴出器を提案するものである。
【０００５】
【課題を解決するための手段】
本請求項１発明の液体噴出器は、上記課題を解決するため、容器体11上部に嵌着した装着キャップ12中央を貫通したステム13を介して上方付勢状態で上下動可能に突出した噴出ヘッド14を押し下げることにより、容器体内液体が噴出ヘッド14の前部から突出したノズル筒15より噴出する如く構成してなる液体噴出器に於いて、前部を開口した有頂筒状で、且つ、ステム13両側面及び後面と、噴出ヘッド上面及び両側面及び後面とを被覆する基部16a 下端縁を、装着キャップ12上面中央部に突設した環状の係止突条17外周に着脱自在に嵌合させるとともに、基部16a の前部開口縁より、ノズル筒15上面及び両側面を被覆するノズル筒被覆部16b を延設してなるキャップ本体16と、ノズル筒被覆部16b の頂板前縁に回動可能に上縁を連結するとともに、裏面より突設した嵌合筒18をノズル筒15先端に着脱可能に嵌合させた蓋板19とからなるキャップＡを備えてなることを特徴とする液体噴出器として構成した。
【０００６】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
図面に示す如く、本発明の液体噴出器10は、容器体11上部に嵌着した装着キャップ12中央を貫通したステム13を介して上方付勢状態で上下動可能に突出した噴出ヘッド14を押し下げることにより、容器体内液体が噴出ヘッド14の前部から突出したノズル筒15より噴出する如く構成している液体噴出器の改良に係わる。
【０００７】
従って、これら噴出器に於ける内蔵ポンプ機構は、従来のこの種の噴出器に採用されているものであればいかなるものであっても採用でき、その具体的な一例を挙げれば、例えば、外周上部より二重筒状に突設した装着キャップを、容器体の口頚部外周に着脱可能に嵌合させることにより、容器体内にシリンダ下部を垂下させた状態で固定した吸い込み弁付きのシリンダと、シリンダ下端に上端を連結し、下端を容器体内下部に垂下させた吸い上げパイプと、シリンダ内周に摺動可能に嵌合させた環状ピストンを下部外周に連係させたステムの上端を、コイルスプリング等により上方付勢させて上下動可能にシリンダ上方に突出させ、その上端にノズル筒付き噴出ヘッドを嵌着固定させた上下動部材と、ステム内に設けた吐出弁とを備えたものが挙げられる。
【０００８】
そして、噴出ヘッドを押し下げることにより加圧されたシリンダ内の液が、ステム内を通り、吐出弁を開いてノズル筒より噴出し、また、噴出ヘッドの上昇の際には、シリンダ内が負圧化して吐出弁が閉じ、吸い込み弁が開いて、容器体内の液を吸い上げパイプを介してシリンダ内に導入する。
【０００９】
本発明噴出器は、従来のこの種の噴出器に於いて、特殊構成の合成樹脂製キャップＡを備えて構成している。このキャップＡは、前部を開口した有頂筒状で、且つ、ステム13両側面及び後面と、噴出ヘッド上面及び両側面及び後面とを被覆する基部16a 下端縁を、装着キャップ12上面中央部に突設した環状の係止突条17外周に着脱自在に嵌合させるとともに、基部16a の前部開口縁より、ノズル筒15上面及び両側面を被覆するノズル筒被覆部16b を延設してなるキャップ本体16と、ノズル筒被覆部16b の頂板前縁に回動可能に上縁を連結するとともに、裏面より突設した嵌合筒18をノズル筒15先端に着脱可能に嵌合させた蓋板19とから構成している。
【００１０】
上記の如く構成した噴出器を使用する場合について説明すると、不使用時は、図１に示す如くキャップＡを、その蓋板19の嵌合筒18をノズル筒15先端部に嵌着させ、また、キャップ本体基部16a 下端縁を係止突条17外周に嵌合させて装着させておく。使用時には、蓋板19を外した後、基部16a 下端縁の嵌合を外してキャップＡを取り除き、次いで噴出ヘッド14を押し下げることにより、内蔵ポンプ機構の作用で容器体内の液をノズル筒15より噴出する如く構成している。
尚、上記各部材は主として合成樹脂により形成し、必要に応じてエラストマー，金属等を併用して形成すると良い。
【００１１】
【発明の効果】
以上説明した如く本発明液体噴出器は、既述構成としたことにより、特に、前部を開口した有頂筒状で、且つ、ステム13両側面及び後面と、噴出ヘッド上面及び両側面及び後面とを被覆する基部16a 下端縁を、装着キャップ12上面中央部に突設した環状の係止突条17外周に着脱自在に嵌合させるとともに、基部16a の前部開口縁より、ノズル筒15上面及び両側面を被覆するノズル筒被覆部16b を延設してなるキャップ本体16と、ノズル筒被覆部16b の頂板前縁に回動可能に上縁を連結するとともに、裏面より突設した嵌合筒18をノズル筒15先端に着脱可能に嵌合させた蓋板19とからなるキャップＡを備えているので、噴出器使用時にはキャップを外して使用するため、液の噴出の際に邪魔となることがなく、しかも、噴出器不使用時には基部16a の存在で噴出ヘッドを押し下げることを防止するため、不用意な液の漏出をおこす虞はなく、また、ポンプへの装着も極めて容易であり、取り扱い上極めて便利である。
【００１２】
また、当然蓋板19の嵌合筒18嵌着時には従来品と同様、ノズル筒内の乾燥等を防止することができ、ノズル筒内の液の固化を防止することができるのはいうまでもない。
