Description

【0001】
【発明の属する技術分野】
本願の発明は、二液を混合して使用する溶液が必要とされる際に、薬剤その他の異なる二つの溶液を必要な量だけ混合して使用するための溶液を収容した混合容器に係わるもので、中でも、二つの溶液をそれぞれ別個に収容した二つの収容容器が一体に形成されていて、混合される溶液を二つの容器から一定量ずつ同時に注出させて、混合して使用するための二液注出容器に関するものである。
【0002】
【従来の技術】
従来から各種の治療薬や消毒剤または栄養剤、あるいは、毛染め剤その他の化粧料や各種の接着剤等の二種類の異なる溶液を混合してから使用するような液状物は、予め混合した状態で容器内に保存しておくと、時間が立つに連れて化学的な反応を生じたり、溶媒が蒸発したり、凝縮して沈殿したり、硬化したりする等の不都合が発生して効力を失うことがあるので、これらの異なる二つの溶液はそれぞれ別個の容器に収容しておいて、使用する際に、二つの溶液をそれぞれ別の容器に移して混合するか、あるいは、二つの容器の開口部を合わせて一方の容器にまとめてから混合してから、使用するのが一般的であった。
【0003】
しかし、上記したような混合方法に於いては、いずれの場合に於いても、収容されている内溶液を一旦容器から注出しながら他の容器に移さなければならないことから、内溶液を移し替える操作を行う際に、溶液を容器外にこぼすことがあるので、慎重に取り扱わなくてはならず、非常に面倒な点があった。
そこで、このような面倒で不具合な点を改良して、容器内に収容した二種類の溶液を、もっと簡単に混合可能にした各種の二液混合容器が提案されている。
【0004】
別個に収容された二種類の溶液を、外部に漏らすことなしに簡単に混合可能にした二液混合容器として、実公平3−4352号公報や実開平5−35652号公報等に記載するような混合容器が知られている。
これらの混合容器は、筒状をした胴部の上端に立設した広口の口頸部の内周面に中栓を嵌合した下部容器体と、前記広口の口頸部の外周面に底部の筒状部を螺合させた注出口部を有する上部容器体とからなる、溶液が収容された二つの容器体を上下に連結した構造の容器である。
そして、上部容器体を捻じって下降させることにより、前記上部容器体の注出口部のテーパー内面に垂設した押し下げ棒、または、下部容器体の底壁面に立設した押し上げ筒により前記中栓を押し下げるか、押し上げることにより仕切り体をなくして二つの容器体を連通させて、上下の容器体の内溶液を容器内で混合できるようにしたものである。
【0005】
しかし、上記したような従来の混合容器では、上部容器体と下部容器体とを仕切っていた中栓を外すことにより二液を混合させるようにしたものであるから、上下の溶液が全て一度に混合されることになり、必要とする量以上の混合液体が生成される場合が発生すると、使い残された混合液体が長期の保存に適さないものであれば、使用されずに残された混合液体は廃棄されることになり、経済的に無駄になるという欠点があった。
そこで、このような経済的な無駄をなくすようにした二液混合容器として、使用する度に必要とする量だけを同時に注出して混合できるようにした二液混合容器が考えられるようになった。
【0006】
そのような二液混合容器の一つの実施例として、特開平7−291365号や特開平7−315448号公報等に記載するように、異なる溶液を収容してなる同一構造の二つの容器体を、左右に立設した状態で胴部を一体に連結させて注出可能にした二液混合容器が提案されている。
上記公報等に記載される発明は、図9に示すように、溶液を収容する中空容器32の肩部から傾斜して立設する口頸部32aの外周に螺合させた蓋体33の頂壁に設けた内外のガイド筒33a,33b間にノズル34を摺動可能に設けて形成した二つの容器体31a,31bを、図8に見るように、前記ノズル34がハの字状になるようにして胴壁部を接合して、内溶液を注出可能に構成した二液混合容器31である。
【0007】
上記のような構成をしたは、図9に示すように、ノズル34が下降した状態ではノズルの下部周壁が外気流入口を塞ぐと共に、栓筒35の上端部がノズル孔を閉塞して、内溶液の注出が阻止されている。
そこで、二つの容器体のそれぞれのノズル34の摘み36を指先に掴んで引き上げると、ノズル34のテーパー状内面と栓筒35との間に隙間ができてノズル孔が開くと同時に外気流入口が開口して、内溶液が注出可能になるので、図8に示すように、混合容器31を手中に持って傾けることにより、それぞれのノズル34a,34bから異なる内容液が同時に流出して、直ちに合流、混合されて使用に供される。
そして、容器体内の溶液が外部に流出して容量が減少した分だけ、容器外の空気が外気流入口から流入して吸気管37を経て中空容器32内に取り入れられるので、二液混合容器31が潰れる等の変形を生じることはない。
【0008】
上記したような構成をした発明の注出混合容器は、使用するに当たって混合する際に、必要とするだけの量を容器から簡単に注出できて、そして、注出と同時に混合して使用できるようにしたものであるから、従来の混合容器のように、混合された溶液が容器内に残って無駄になるようなことがなくて、また、混合される溶液がこぼれるようなこともなくて非常に便利で、経済的である。
しかし、このような構成をした混合容器から注出される溶液の量は、ある程度は一定した量に近い範囲内で注出することができるが、決められた一定の量を正確に注出することは非常に困難であることから、一定量の溶液を正確に注出できるようにした混合容器の出現が望まれる。
【0009】
【発明が解決しようとする課題】
本願の発明は、異なる二種類の溶液を別個に収容した二つの円筒状の容器体を、同時に注出できるように一体に連結した注出容器本体に形成すると共に、該注出容器本体内に異なる種類の溶液を別々に収容して、前記した異なる溶液を必要とするだけの一定の量を正確に注出できるように形成して、前記注出容器本体から注出された内溶液を、即座に混合することができて、無駄なく使用できるように構成した二液注出容器を提供するのを目的とする。
【0010】
【課題を解決するための手段】
本願発明は、混合して使用する溶液が別々に収容される円筒容器体を、筒状の上端部に注出口を設けた円筒体に形成すると共に、該円筒体内に円筒状をしたピストンを往復動可能に挿入できるようにした注射器状に形成する。
このようにして注射器状に形成された混合溶液を収容する円筒容器体の二つを、その胴壁を接するようにして並列状に立設せしめて一体に連結すると共に、連結された円筒容器体に沿って階段状をしたラチェット歯を設けて二液を収容する注出容器本体を形成する。
【0011】
そして、上記のように形成された注出容器本体の円筒容器体に挿入可能に形成された円筒状のピストンを連結部材により連結されたピストン体を形成して、前記注出容器本体に該ピストン体を摺動自在に装着して同時に前進可能に形成すると共に、前記注出容器本体の先端部に注出ノズルを有する注出ヘッドを嵌合して前記注出口に連通せしめて同時に二液を注出可能に形成して、前記ピストン体に設けた操作レバーの先端部を前記注出容器本体のラチェット歯に係合せしめて、前記操作レバーの揺動操作に伴ってピストン体を前進可能にして、円筒容器体内の二つの溶液を正確に一定量ずつ同時に注出できるように構成する。
【0012】
【発明の実施の態様】
溶液を収容可能に形成した円筒体の上端部に注出口を形成すると共に、該円筒体に円筒状のピストンを進退自在に挿入可能に形成して、混合溶液が収容される注射器状をした円筒容器体2aを形成する。
上記のように形成した注射器状の二個の円筒容器体2aを、円筒壁が接するように並列状に立設せしめて円筒体連結部材(第一連結部材)7により一体に連結すると共に、前記円筒容器体の円筒壁に沿って設けられたラチェット部材4の表面に階段状に形成したラチェット歯4aを形成して、異なる二液を収容する注出容器本体2を形成する。
【0013】
また、前記注出容器本体2を形成した円筒容器体2a内に密着して挿入可能にした円筒状のピストン3aを形成して、該ピストンの二個を並列状に立設した状態にしてピストン連結部材(第二連結部材)8により一体に結合すると共に、前記円筒容器体内に進退自在に挿入可能に形成して、前記ピストンに沿って設けられた支持体5に前記ラチェット歯4aと係合する操作レバー9を揺動可能に設けて、前記円筒容器体2a内に二つのピストン3aを同時に押し込み可能となしたピストン体3を形成する。
【0014】
そして、上記のように形成された注射器状をした二個の円筒容器体2aからなる注出容器本体2に、二個の円筒状のピストン3aからなるピストン体3を進退自在に挿入して一体に結合して、二種の混合溶液を収容する容器本体を形成すると共に、前記注出容器本体2のラチェット部材4に設けられたラチェット歯4aに、前記ピストン体3の支持体5に設けられた前記操作レバー9の先端部の係合歯9aを係合せしめて、操作レバー9を揺動させることによりピストン体3を同時に一定長さだけ先方へ順送りさせて、注出容器本体内に収容される溶液が一定量だけ正確に注出されるように構成する。
【0015】
上記のように構成された注出容器本体2の二つの円筒容器体2a内に、異なる二種類の溶液を別々に収容して、前記注出容器本体2の上端部に前記円筒容器体2aに設けた注出口2bと連通する注出ヘッド6を嵌合、固定すると共に、注出ヘッド6の注出ノズル6aに蓋体10を螺着、密閉して、混合される溶液を前記注出ノズル6aから一定した等量ずつを正確に注出できるようにした二液注出容器1を形成する。
このように形成された二液注出容器1から内溶液を注出して使用するには、該二液注出容器の注出ノズル6aに螺着された蓋体10を外してから、二液注出容器を手中に持って傾けて、前記操作レバー9を指先で押圧して揺動させて、ラチェット歯4aに係合している操作レバー先端の係合歯9aを一段ずつ送ることにより、ピストン体3を一定長さだけ押し進めて、二つの円筒容器体2a内の溶液を等量ずつ注出せしめると共に、注出された溶液を混合して使用する。
【0016】
【実施例】
本願発明の二液注出容器について、最適な一つの実施例に基づいて、以下に図面を参照しつつ説明する。
本願の発明は、図1及び図3に示すように、注射器状に形成された円筒容器体2aを二個並列状に立設して連結した注出容器本体2と、前記円筒容器体2aに進退自在に挿入可能に形成した円筒状のピストン3aを二個並列状に立設して連結したピストン体3とを結合せしめて同時に押し出し可能に形成して、前記ピストン体3に設けられた操作レバー9により該ピストン体3を一定長さだけ押し進めて、注出容器本体2の二つの円筒容器体内に収容した異なる溶液を等量ずつ注出せしめると同時に、注出された溶液を即座に混合して使用するように形成された二液注出容器1である。
【0017】
上記のように形成された二液注出容器1は、熱可塑性合成樹脂を射出成形により円筒体を成形して、図5に示すように、該円筒体の先端部には注出ヘッド6を嵌着可能な注出口2bを形成すると共に、下端部には円筒状のピストン3aを摺動自在に挿入可能な開口部を形成して、ほぼ注射器状をした円筒容器体2aに成形する。
そして、図3に示すように、前記円筒容器体2aを二つ並列状に立設して胴壁部が接するような状態にして下端部を第一連結部材7により連結して、該第一連結部材7から前記二つの円筒容器体2aの側壁部に沿うようにして延設せしめてラチェット部材4を設けると共に、前記ラチェット部材4の表面にラチェット歯4aを階段状に形成して、前記円筒容器体2aの先端部に注出ヘッド6を嵌着せしめて、円筒容器体2aの注出口2bに注出ノズル6aを連通するように結合された注出容器本体2を形成する。
【0018】
また、前記した注出容器本体と同様に熱可塑性合成樹脂を射出成形して円筒状に成形して、図3に示すように、前記円筒容器体2a内に摺動自在に挿入可能な円筒体に成形すると共に、該円筒体の先端部に摺動部材11を嵌合、固定して前記円筒容器体2aの内周面に密接して摺動するようにしたピストン3aを形成する。
そして、図6に示すように、前記円筒状のピストン3aを二つ並列状に立設して前記注出容器本体2に挿入可能な状態にして後端部を第二連結部材8により連結すると共に、該連結部材から二つの円筒状のピストン3aの側壁面に沿うようにして延設せしめて操作レバーの支持体5を設けて一体に連結して、前記支持体5の先端部に設けた軸受け部5aに操作レバー9を揺動可能に設けると共に、前記操作レバー9の先端に前記注出容器本体2のラチェット歯4aに係合する係合歯9aを設けたピストン体3を形成する。
【0019】
上記のようにして形成された注出容器本体2の二つの円筒容器体2aに対して、前記のように形成されたピストン体3の二つのピストン3aを、図3に示すように摺動自在に挿入せしめて、図2に示すように一体に連結して、前記支持体5の先端部の軸受け部5aに弾性体12を介して揺動可能に保持された操作レバー9は、その先端部に形成された係合歯9aが前記円筒容器体2aに設けられたラチェット部材4のラチェット歯4aに係合するように固定される。
【0020】
そして、上記のように固定される操作レバー9は、図4に示したように、前記支持体5の軸受け部5aの下に固定された弾性体12に連結されて、湾曲した弾性体12により上方へ付勢された状態で支持体5の先端の楕円形をした軸受け部5aに揺動可能に保持されて、操作レバーの先端部に形成された係合歯9aの先端面が、前記注出容器本体2のラチェット部材4に形成されたラチェット歯4aの係止面に係合されている。
従って、前記操作レバー9を指先で押圧すると、操作レバーの支持軸が押し下げられて係合歯9aがラチェット歯4aから外れ、指先の押圧力を除くと弾性体12の復元力により上に移動されて、係合歯9aが一つ上のラチェット歯4aに係合する揺動運動を繰り返すことにより、前記ピストン3aをラチェット歯4aの一つ分ずつ押し進めて、円筒容器体2a内の溶液を一定量ずつ正確に注出せしめて二液を混合可能にした注出容器1が構成される。
【0021】
上記のように構成された二液混合可能な注出容器には、注出容器本体2の先端部の注出口2bから二つの円筒容器体2aの内部に混合される溶液を収容した後で、前記注出口2bに注出ノズル6aを連通せしめて注出可能にして嵌着し、前記円筒容器体2aの先端部に注出ヘッド6を嵌合、固定してから、前記注出ヘッド6の注出ノズル6aに蓋体10を嵌着せしめて密閉した定量注出が可能な二液注出容器1が形成される。
【0022】
上記のようにして定量注出を可能に形成された二液注出容器1から内溶液を定量に注出して混合して使用に供するには、前記注出ヘッド6の注出ノズル6aに嵌着して密閉した蓋体10を外して注出ノズル6aが開口してから、図5(a)に示すように、前記操作レバー9を弾性体12の力に逆らって指先で押圧すると、操作レバー9の支持軸が楕円形の軸孔に沿って押し下げられて、図5(b)に示すように、操作レバー9は軸受け部5aの底部を支点として揺動するので、操作レバー先端の係合歯9aがラチェット歯4aの端面から離れる。
【0023】
そこで、図5(c)に示すように操作レバー9から指先を離すと、弾性体12の復元力により操作レバーが押し上げられて支持軸が楕円形の軸孔に沿って移動するので、操作レバー先端の係合歯9aは、図5(d)に示すように、一つ上のラチェット歯4aの傾斜歯面に乗り上げることになる。
このようにして、係合歯9aがラチェット歯4aの傾斜歯面に乗り上げた操作レバー9は、更に弾性体12の復元力により押し上げられるが、その際に、前記ピストン体3も弾性体12の復元力により押し進められて、図5(e)に示すように、操作レバーの係合歯9aはラチェット歯4aの係止端面に当接して係止される。
【0024】
上記したように本願発明の二液注出容器1は、操作レバーを揺動可能に保持する支持体5の先端の軸受け部5aを楕円形をした軸孔に形成して、操作レバー9を指先で押圧させることにより先端部の係合歯9aを簡単に揺動させることができるようにしたので、前記操作レバー9を揺動させる度に、先端部の係合歯9aがラチェット歯4aの一段分ずつ先方へ順送りされるので、操作レバーの係合歯9aが前進する度ごとに、前記ピストン体3は弾性体12が復元する際の反発力により、ラチェット歯4a一段分の距離だけ円筒容器体2a内に確実に押し込まれて、混合される内溶液が注出ヘッド6の注出ノズル6aからラチェット歯4aの一個分に相当する量だけ確実に押し出される。
【0025】
本願発明は、操作レバーを保持する支持体5の先端の軸受け部5aを、楕円形をした軸孔に代えて円形状をした軸孔に形成しても、前記した場合と同様に操作レバーを揺動可能に保持することができる。
しかし、その場合には、操作レバーの支持軸が下方へ移動することがないので、操作レバー先端部の係合歯9aをラチェット歯4aから離して次のラチェット歯4aの傾斜面に係合するよう揺動させるには、操作レバーをやや強く押圧して操作レバーの支持体5を変形させて揺動させることが必要である。
【0026】
尚、上記した二液注出容器に於いては、注出容器本体2を形成する二つの円筒容器体2aは同じ内径にした同内容積に形成し、また、ピストン体3を形成する両ピストン3aは同じ外径にした同体積の円筒体に形成したものを一体に連結して、混合する内溶液が等量であるように形成したが、本願の発明は、このように注出容器本体とピストン体を円筒形に限定する必要もなくて、多角形をした筒状容器体で形成してもよくて、また、注出容器本体の内容積を等しくする必要もなくて、異なる内容積の筒状容器体からなる注出容器本体に形成してもよい。
更に、本願発明は、注出容器本体を二つの筒状容器体で形成したものに限らず、三つ以上の筒状容器体で形成することも可能である。
また、上記した注出容器体2は、別体に成形した筒状容器体を連結部材により連結して一体に形成することも、また、射出成形等により一体成形することも可能であり、同様に、ピストン体3についても、別体に成形した筒状のピストンを連結部材により連結して一体に形成することも、射出成形等により一体成形することも可能である。
【0027】
例えば、図7に示したように、注出容器本体22を形成する二つの円筒容器体22a,22bの内径を異なるものにして、内容積が2:1あるいは3:1等となるように形成して、これに摺動自在に装着するピストン体33を形成する二つのピストン33a,33bの外径も前記円筒容器体22a,22bの容積比に見合った異なるものにすることにより、注出する内溶液の混合比率を変えたものにすることが可能になる。
【0028】
また、前記した二液注出容器に於ける注出容器本体2およびピストン体3は、熱可塑性合成樹脂の射出成形により、それぞれ図3および図6に見られるように、二つの円筒容器体2aは第一連結部材7により、また、二つのピストン3aは第二連結部材8により連結された状態に一体成形されたものであるが、本願の発明の注出容器本体2およびピストン体3は、このような一体成形したものに限定される必要はない。
【0029】
例えば、図7に見られるように、熱可塑性合成樹脂やガラスその他により注出容器本体22を形成する二つの円筒容器体22a,22bを別々に成形した下端部を、ピストン体33が摺動自在に挿入できるように別体に形成した第一の連結部材37により連結した注出容器本体22を形成して、また同様に、ピストン体33を形成する二つのピストン33a,33bを別々に成形した下端部に、別体に形成された第二の連結部材38を嵌着して固定して連結したピストン体33を形成して、前記注出容器本体22内にピストン体33を摺動自在に挿入できるように形成することも可能である。
前記円筒容器体22a,22bには上記した実施例と同じように、それぞれの上端部に注出口23a,23bが設けられ、また、前記ピストン33a,33bの上端には摺動部材21a,21bが設けられている。
【0030】
【発明の効果】
本願発明の多液注出容器は、注射器状に形成した複数の筒状容器体を並列状に連結して一体に形成した注出容器本体に、複数のピストンを並列状に連結して前記注出容器本体に挿入可能に形成したピストン体を摺動自在に装着すると共に、ピストン体に設けた操作レバーの係合歯を注出容器本体に設けたラチェット歯に係合させて、操作レバーの揺動させることによりピストン体を前進させて、注出容器本体の複数の円筒容器体内に収容された溶液を注出するように構成したので、ピストン体が一定長さだけ確実に押し進めることができて、同時に複数の溶液を決められた量だけ正確に注出することが可能である。

BACKGROUND OF THE INVENTION
The invention of the present application relates to a mixing container containing a solution for mixing and using two or more different solutions required for use when a solution for mixing two liquids is required. In particular, two storage containers separately storing the two solutions are integrally formed, and the mixed solutions are simultaneously poured out from the two containers by a predetermined amount, and used for mixing and use. It relates to a two-component dispensing container.
[0002]
[Prior art]
Conventionally, liquids such as various therapeutic agents, disinfectants, nutrients, hair dyes and other cosmetics and various adhesives that are used after being mixed are mixed in advance. If stored in a container in a state, the chemical reaction may occur over time, the solvent may evaporate, condense and precipitate, or harden, causing problems. Since these two different solutions are stored in separate containers, the two solutions can be transferred to separate containers for use or mixed. It was common to use after combining the openings of these together into one container and mixing.
[0003]
However, in the mixing method as described above, in any case, since the contained internal solution must be once poured out of the container and transferred to another container, the internal solution is transferred. When performing the operation, the solution may be spilled out of the container, so it must be handled with care, which is very troublesome.
In view of this, various two-component mixing containers have been proposed in which such troublesome and inconvenient points are improved and two kinds of solutions contained in the container can be mixed more easily.
[0004]
As described in Japanese Utility Model Publication No. 3-4352, Japanese Utility Model Publication No. 5-35652, etc., as a two-component mixing container in which two separately stored solutions can be easily mixed without leaking outside. Mixing containers are known.
These mixing containers are composed of a lower container body in which an inner plug is fitted to an inner peripheral surface of a wide-mouthed mouth-and-neck portion erected at the upper end of a cylindrical body, and a bottom portion on an outer peripheral surface of the wide-mouthed neck portion. It is a container of the structure which connected the two container bodies in which the solution was accommodated which consisted of the upper container body which has the spout part which screwed this cylindrical part up and down.
Then, by twisting and lowering the upper container body, the inner plug is pushed down by a push-down rod suspended on the tapered inner surface of the spout portion of the upper container body or a push-up cylinder erected on the bottom wall surface of the lower container body By pushing down or pushing up, the partition body is eliminated to allow the two container bodies to communicate with each other so that the solutions in the upper and lower container bodies can be mixed in the container.
[0005]
However, in the conventional mixing container as described above, the two liquids are mixed by removing the inner plug that separates the upper container body and the lower container body. If a mixed liquid exceeding the required amount is generated, if the mixed liquid left over is not suitable for long-term storage, the mixed liquid left unused. The liquid was discarded and was disadvantageous in that it was wasted economically.
Therefore, as a two-component mixing container that eliminates such economical waste, a two-component mixing container that can be poured and mixed only in an amount necessary for each use has come to be considered. .
[0006]
As one example of such a two-component mixing container, as described in JP-A-7-291365 and JP-A-7-315448, two container bodies having the same structure containing different solutions are provided. In addition, a two-component mixing container has been proposed in which the body portion is integrally connected in a state where the body portion is erected on the left and right sides and can be poured.
The invention described in the above publications, as shown in FIG. 9, includes a top of a lid 33 screwed onto the outer periphery of a mouth-and-neck portion 32a that stands upright from the shoulder of a hollow container 32 that contains a solution. As shown in FIG. 8, two nozzle bodies 31a and 31b formed by slidably providing a nozzle 34 between inner and outer guide cylinders 33a and 33b provided on the wall, the nozzle 34 has a letter C shape. Thus, it is the two-component mixing container 31 which joined the trunk | drum wall part and was comprised so that extraction of an inner solution was possible.
[0007]
With the above configuration, as shown in FIG. 9, when the nozzle 34 is lowered, the lower peripheral wall of the nozzle blocks the external air flow inlet, and the upper end of the plug cylinder 35 closes the nozzle hole, Solution dispensing is blocked.

Since the inner solution can be poured by opening, different contents liquids are simultaneously discharged from the respective nozzles 34a and 34b by tilting the mixing container 31 in the hand as shown in FIG. Combined and mixed for use.
Then, since the solution in the container flows out to the outside and the volume is reduced, the air outside the container flows in from the external air flow inlet and is taken into the hollow container 32 through the intake pipe 37. Therefore, the two-liquid mixing container 31 No deformation such as crushing occurs.
[0008]
The mixing container of the invention having the above-described configuration can be used by simply mixing out the necessary amount from the container when mixing for use, and can be mixed and used at the same time as the dispensing. As a result, the mixed solution does not remain in the container and is not wasted, and the mixed solution is not spilled. Very convenient and economical.

The ratchet member 4 is provided so as to extend from the connecting member 7 along the side wall portions of the two cylindrical container bodies 2a, and ratchet teeth 4a are formed in a stepped manner on the surface of the ratchet member 4, and the cylinder The pouring head 6 is fitted to the tip of the container body 2a to form the pouring container body 2 coupled so as to communicate the pouring nozzle 6a with the pouring port 2b of the cylindrical container body 2a.
[0018]
Also, a cylindrical body that can be slidably inserted into the cylindrical container body 2a as shown in FIG. 3 by injection molding a thermoplastic synthetic resin into a cylindrical shape in the same manner as the above-described dispensing container body. And a sliding member 11 is fitted and fixed to the tip of the cylindrical body to form a piston 3a that slides in close contact with the inner peripheral surface of the cylindrical container body 2a.
Then, as shown in FIG. 6, two cylindrical pistons 3 a are erected in parallel so that they can be inserted into the dispensing container main body 2, and the rear end portion is connected by the second connecting member 8. In addition, the support member 5 of the operation lever is provided so as to extend along the side wall surfaces of the two cylindrical pistons 3a from the connection member, and is integrally connected to be provided at the tip of the support member 5. An operating lever 9 is provided on the bearing portion 5a so as to be swingable, and a piston body 3 is formed in which an engaging tooth 9a that engages with a ratchet tooth 4a of the dispensing container body 2 is provided at the tip of the operating lever 9.
[0019]
As shown in FIG. 3, the two pistons 3a of the piston body 3 formed as described above are slidable with respect to the two cylindrical container bodies 2a of the dispensing container body 2 formed as described above. As shown in FIG. 2, the operation lever 9 is integrally connected as shown in FIG. 2 and held swingably on the bearing portion 5 a of the support portion 5 via the elastic body 12. The engaging teeth 9a formed on the cylindrical container body 2a are fixed so as to engage with the ratchet teeth 4a of the ratchet member 4 provided on the cylindrical container body 2a.
[0020]
The operation lever 9 fixed as described above is connected to the elastic body 12 fixed below the bearing portion 5a of the support 5 as shown in FIG. The tip surface of the engaging tooth 9a formed at the tip of the operation lever, which is swingably held by the elliptical bearing portion 5a at the tip of the support 5 while being biased upward, The ratchet member 4 of the outlet container body 2 is engaged with a locking surface of a ratchet tooth 4a.
Accordingly, when the operating lever 9 is pressed with the fingertip, the supporting shaft of the operating lever is pushed down, and the engaging teeth 9a are disengaged from the ratchet teeth 4a. When the pressing force of the fingertip is removed, the elastic body 12 moves upward. Then, by repeating the swinging movement in which the engaging tooth 9a engages with the upper ratchet tooth 4a, the piston 3a is pushed forward one by one by the ratchet tooth 4a, and the solution in the cylindrical container body 2a is kept constant. A pouring container 1 is constructed in which the two liquids can be mixed by accurately pouring out the amount.
[0021]
In the two-liquid-mixable pouring container configured as described above, after containing the solution to be mixed into the inside of the two cylindrical container bodies 2a from the pouring outlet 2b at the tip of the pouring container body 2, The pouring nozzle 6a is connected to the pouring port 2b so that the pouring can be performed, and the pouring head 6 is fitted and fixed to the tip of the cylindrical container body 2a. The two-liquid dispensing container 1 capable of quantitative dispensing, which is sealed by fitting the lid 10 on the dispensing nozzle 6a, is formed.
[0022]
In order to pour the inner solution from the two-liquid pour container 1 formed so as to be able to pour out in a fixed amount as described above and mix it for use, it fits into the pour nozzle 6a of the pour head 6. After the cover 10 that has been attached and sealed is removed and the dispensing nozzle 6a is opened, as shown in FIG. 5A, when the operation lever 9 is pressed with the fingertip against the force of the elastic body 12, The support shaft of the lever 9 is pushed down along the elliptical shaft hole, and as shown in FIG. 5 (b), the operation lever 9 swings with the bottom of the bearing portion 5a as a fulcrum. The artificial tooth 9a is separated from the end face of the ratchet tooth 4a.
[0023]
Therefore, when the fingertip is released from the operation lever 9 as shown in FIG. 5C, the operation lever is pushed up by the restoring force of the elastic body 12, and the support shaft moves along the elliptical shaft hole. As shown in FIG. 5 (d), the leading engagement tooth 9a rides on the inclined tooth surface of the upper ratchet tooth 4a.
In this way, the operating lever 9 with the engaging teeth 9a riding on the inclined tooth surfaces of the ratchet teeth 4a is further pushed up by the restoring force of the elastic body 12.

The inner solution that is pushed into the body 2a and mixed is reliably pushed out from the dispensing nozzle 6a of the dispensing head 6 by an amount corresponding to one ratchet tooth 4a.
[0025]
In the present invention, even if the bearing portion 5a at the tip of the support body 5 that holds the operation lever is formed in a circular shaft hole instead of the elliptical shaft hole, the operation lever is provided in the same manner as described above. It can be held swingably.
However, in this case, since the support shaft of the operating lever does not move downward, the engaging tooth 9a at the tip of the operating lever is separated from the ratchet tooth 4a and engaged with the inclined surface of the next ratchet tooth 4a. In order to make it swing, it is necessary to slightly press the operating lever to deform and swing the support 5 of the operating lever.
[0026]

In addition, the piston body 3 can be integrally formed by connecting cylindrical pistons formed separately to each other by a connecting member, or can be integrally formed by injection molding or the like.
[0027]
For example, as shown in FIG. 7, the inner diameters of the two cylindrical container bodies 22a and 22b forming the pouring container body 22 are made different from each other so that the inner volume is 2: 1 or 3: 1. Then, the outer diameters of the two pistons 33a and 33b forming the piston body 33 slidably mounted on the piston body 33 are also made different from each other in accordance with the volume ratio of the cylindrical container bodies 22a and 22b. It is possible to change the mixing ratio of the inner solution.
