【発明の属する技術分野】
本願の発明は、中空容器内に収容した痒み止めや消毒剤等の薬液、または、毛髪剤やファンデーション等の液体化粧料、あるいは、窓ガラスの曇り止めや撥水剤等の液体状の各種の溶液を塗布する液体塗布容器に係わるもので、特に、各種薬液等を内部に収容した中空容器の口頸部にスポンジやフェルトその他の軟質で液体吸収性が良好な材質からなる塗布部材を設けておいて、目的とする塗布面に塗布部材を直接に押し当てるだけで内溶液を簡単に塗布することができるようにした液体塗布容器に関するものである。
【０００２】
【従来の技術】
従来から一般に使用されている液体容器は、使用するに際して容器の蓋を開いてから、痒み止めや消毒剤等の薬液は、綿棒や脱脂綿等に吸収させてから塗布したり、あるいは、ファンデーションやローション等の液体化粧料は、適当な量を手のひらに受けてから肌に塗布したり、撥水剤やワックス等の液体は、スポンジやタオル等に移してから塗布するものが一般的であったが、このような形式の液体容器は、内溶液を注出するのが面倒で、余分に注出させたり、また、内溶液が手に付着して汚れたりする等の色々な問題点があった。
【０００３】
そこで、化粧料や薬液等の溶液が収容された中空容器から注出する内溶液を直接に塗布できるようにした各種の液体塗布容器が、特開平１１−１５７５８２号公報や実開昭６２−１７９０７０号、実開平７−４０５２０号公報その他に提案されている。
これらの液体塗布容器は、中空容器から内溶液を注出して直接塗布することができて、手間がかからず簡単に塗布することができるので非常に便利であるが、いずれの塗布容器も、口頸部に設けた球状または半球状をした塗布体を塗布面に押し当てることにより、液体の流出口を開いて内溶液を注出させて塗布体面に付着させるようにしたものである。
【０００４】
しかし、前記した塗布体は、シリコンゴムや合成樹脂等の吸湿性の低いもので形成されているので塗布効率が悪くて、また、上記した液体塗布容器は、ファンデーション等の化粧料や痒み止め等の薬液等の異質の溶液に対しては共用することができないし、更に、口頸部と塗布体との間が充分な液密状態に保たれていないので、液漏れが発生する恐れがある。
そこで、このような問題点を改善して、化粧料や薬液等の溶液を収容した容器本体の口頸部の注出口に吸湿性と通気性を有するスポンジで形成した塗布体を設けると共に、口頸部に着脱自在に螺合した蓋体を回動することにより注出口を開閉して塗布可能に形成した液体塗布容器を、出願人は先に、実開平１−１６１４５９号や実公昭６１−２２８４３号公報等に提案している。
【０００５】
上記公報等に見る液体塗布容器は、図５に示すように、容器本体２１の口頸部に外蓋体螺合部２１ａと密封円筒螺合部２１ｂとを形成して、前記密封円筒螺合部に密封円筒２３を螺合すると共に、前記密封円筒螺合部の先端部に通水性塗布体２６を張設して、内容液を塗布可能に構成したものである。
上記液体塗布容器は、図６に示すように、容器本体２１の口頸部の密封円筒螺合部２１ｂの先端部に、注出口２２を設けると共にその外周に環状密封片２２ａを設けて、前記密封円筒螺合部に密封円筒２３を螺合して、前記密封円筒に環状密封片２２ａが当接する密封内壁部２３ａを設けると共に、密封円筒の頂壁部に栓部２４と注液孔２５とを設けて、注液孔２５の外側に通水性塗布体２６を張設して、蓋体螺合部に内蓋２７を有する外蓋体２８を着脱可能に螺着して、密閉するように形成したものである。
【０００６】
このように形成された液体塗布容器は、外蓋体２８を回動して開蓋することにより密封円筒２３を上昇させて注出口２２を開口して、内溶液を注出せしめて前記塗布体２６に含浸させて塗布できるようにしたものであるから、外蓋体２８を回動させて容器本体１から分離するだけで、塗布体に含浸した内溶液を直接塗布面に塗り付けることができて便利であるが、注出口を開閉する構造および塗布体の支持構造が複雑になり、また、開口度合いの調節ができないことから改良の余地がある。
そこで、このような注出口および塗布体の支持構造をもう少し簡単にした液体塗布容器として、実開平７−２２５７号公報に見るようなものが提案されている。
【０００７】
上記公報等に記載される液体塗布容器は、図７に見るように、撥水剤等の塗布液を内部に収容する有底の円筒状した中空の容器本体３１の口頸部に、外蓋３４を螺合可能な外筒壁を有する中蓋３２を嵌着して、前記中蓋の上面にドーナツ状に形成した塗布体３３を嵌着、固定して、注出する内溶液を前記塗布体に含浸せしめてガラス等の塗布面に塗布可能に構成したものである。
【０００８】
上記のように構成された液体塗布容器は、図８に示すように、中空の円筒状をした容器本体の口頸部３１ａに中蓋３２を嵌着して、該中蓋の密閉蓋面３２ａに容器本体内と連通する流出孔３９を形成して、前記中蓋部３２の上面に平板状弁体３５を上下動可能に配設すると共に、該弁体の下面の部分に前記流出孔３９を密閉するための栓部３５ａを突設して、前記中蓋３２の蓋面上に塗布体３３を嵌着せしめると共に、該中蓋の外周壁内面に設けた係止突起３２ｂにより固定されている。
そして、前記中蓋３２に外蓋３４を着脱可能に螺着すると共に、前記外蓋３４の天板部の内面には、外蓋を螺着した時に前記平板状弁体３５を押圧して前記平板状弁体の栓部３５ａが、前記中蓋３２に設けられた流出孔３９に栓をするように押圧するための押圧突起３４ａが設けられている。
【０００９】
上記のように形成された液体塗布容器は、図９に示したように、外蓋３４を外した容器本体３１を逆さまにした状態で胴壁を押圧すると、前記平板状弁体３５は塗布体３３側へ移動して、前記流出孔３９が開口するので、容器本体内に収容した溶液が注出して塗布体３３に均一に含浸されて塗布可能になる。
そして、塗布体３３を塗布面に当てて塗布操作を行った後で、容器本体３１を直立状態にして外蓋３４を中蓋３２に螺合すると、前記平板状弁体３５は蓋体の押圧突起３４ａにより押し下げられて、前記栓部３５ａが中蓋３２の流出孔３９を栓して内容液の流出を密閉する。
【００１０】
このように、上記した塗布容器は、布巾や手を汚すことなしに簡単に塗布することができて便利であり、また、容器の口頸部に保持する塗布体を中蓋の係止突起により固定したので、構造が簡単で確実に保持することができるが、しかし、内溶液の注出口を開閉するには、容器本体を直立または倒立させることにより弁体が自重と液圧あるいは外蓋の螺合により移動させて開閉するようにしたものであるから、内溶液が撥水剤や曇止め剤等であればよいが、ファンデーション等の化粧料や粘性が高い液状の内容物の場合には、その注出をスムーズに行うことができず、また、注出量の調節が難しい。
【００１１】
そこで、容器本体の口頸部の注出口および塗布体の支持部の構造が簡単で、且つ、内溶液の吐出口を開閉する弁体を自動的にスムーズに移動させることができて、内溶液の注出量の調整をすることができると共に、痒み止め等の薬液に限らず、化粧料その他の各種の溶液にも対応することができて、収容された内容液を簡単に塗布できるような構造をした液体塗布容器の出現が望まれる。
【００１２】
【発明が解決しようとする課題】
液体塗布容器の塗布体部分を容器本体の口頸部に支持する支持部の構造をできるだけ簡単に形成すると共に、口頸部に設けた塗布体に内溶液を供給するための注出口の弁体を自動的に開閉可能な構造にした液体塗布容器を形成して、前記液体塗布容器内には各種の内溶液が収容することができて、且つ、内容液を簡単に塗布することができるようにした、各種溶液に共用可能な液体塗布容器を形成する。
そして、容器本体の構造が簡単で、塗布する際の使い勝手がよくて、内容液が漏れ出るようなこともなくて、安価に製造することができるようにした液体塗布容器を提供する。
【００１３】
【課題を解決するための手段】
各種の液体化粧料や薬液等の溶液を収容する中空容器の口頸部に、内容液を注出可能な注出口を設けると共に外蓋を螺着可能に形成した中蓋を嵌合または螺合せしめて固定する。
そして、前記中蓋の注出口にピストン状に形成した環状弁体を摺動可能に嵌合せしめて内溶液の注出可能に形成して、塗布体を収容して固定する塗布体受け皿の底部の嵌合筒部を前記環状弁体の周壁内面に嵌合、密着すると共に、塗布体受け皿の側壁部を前記中蓋の外筒内壁面に摺動可能に嵌合せしめて、塗布体受け皿の底壁部に設けた複数の板バネにより受け皿を進退自在に形成する。
上記のように形成した塗布体受け皿内にフェルトやスポンジ等から円盤状に形成した塗布体を嵌合すると共に、受け皿の内壁面に設けた係止片に塗布体の外側面を係止して、塗布体と受け皿とを一体に進退可能に構成する。
【００１４】
【発明の実施の形態】
本願発明は、熱可塑性合成樹脂をブロー成形して、胴壁部１ｂを押圧変形可能に形成した中空容器本体１に各種の溶液を収容してから、前記容器本体の口頸部１ａに、密閉蓋部２ａの下面に内筒７ａと外筒７ｂとからなる嵌合筒７を突設して、容器本体１の口頸部１ａに嵌着可能な中蓋２を形成すると共に、密閉蓋部２ａの上面に塗布体５の受け皿４を収容可能に形成した中蓋２を嵌合、固定し、そして、前記中蓋２の密閉蓋部２ａの中央部に垂設した注出筒２ｂに、ピストン状をした弁体３を嵌合して内溶液を注出可能にした容器体を形成する。
【００１５】
続いて、前記中蓋２に嵌合可能に形成した塗布体５の受け皿４を成形して、前記受け皿４の底部には弁体３を嵌合した嵌合筒４ａを垂設すると共に、該受け皿を上下動させる弾性片（板バネ）４ｂを形成して、また、前記受け皿の周壁４ｃの内面に塗布体を係止する係止突起４ｄを設けて、前記受け皿４に塗布体５を装着して前記係止突起４ｄで係止して塗布可能に形成する。
そして、上記のように形成された受け皿４を前記中蓋２に嵌合せしめると共に、前記嵌合筒４ａに嵌合されたピストン状をした環状の弁体３を注出筒２ｃに嵌合せしめて、内溶液を注出可能に形成した液体塗布容器本体に、外蓋６を被着して螺合せしめて液体塗布容器を構成する。
【００１６】
上記のような構成にした本願発明の液体塗布容器は、使用するに当たって、外蓋を塗布容器本体１から外した後に、容器本体を逆さまにして塗布体５を塗布面に押し当ててから容器の胴壁部１ｂを圧搾することにより、容器本体内に収容された溶液は連通された前記注出筒２ｂおよび環状弁体３の開口部を経て塗布体５へと注出されて、塗布体から塗布面に内容液が塗布される。
このようにして塗布操作が終わったら、塗布体５を塗布面から離してやると、前記受け皿４は弾性片４ｂにより押し上げられて、弁体３と注出筒２ｂの連通状態が解除されて内容液の注出が停止するので、外蓋６を塗布体５に被着して中蓋２に螺合せしめると保存可能な状態になる。
【００１７】
【実施例】
本願発明の液体塗布容器について、以下に最適な一つの実施例に基づいて、図面を参照しつつ詳細に説明する。
本願の発明は、図１に示すように、各種の溶液を収容した中空容器本体１の口頸部に内溶液を注出可能にした嵌合、固定した中蓋２に、塗布体５を嵌着、係止した受け皿４を嵌合せしめて内容液を塗布可能に形成して、前記塗布体に外蓋６を被着して中蓋２に螺合して密閉するように構成した液体塗布容器である。
【００１８】
そして、上記した塗布容器の中蓋２は、図２に示したように、密閉蓋部２ａに垂設した注出筒２ｂ内にピストン状に形成した弁体３を摺動自在に嵌合せしめて、内溶液の注出口を開閉可能となして、更に、前記中蓋２内に、塗布体５を塗布可能に固定した受け皿４を上下動可能に嵌着すると共に、前記受け皿４の底部に設けた嵌合筒４ａを前記弁体３に嵌合せしめて、注出される内溶液を前記塗布体５に含浸可能に形成されている。
【００１９】
中空容器の口頸部１ａに嵌合、固定する前記中蓋２は、熱可塑性合成樹脂の射出成形して、図３に示すように、中蓋の密閉蓋部２ａの下面に内筒７ａと外筒７ｂからなる嵌合筒７を突設して、容器本体１の口頸部１ａの内外面に嵌着可能に形成すると共に、前記内筒７ａの内側に内溶液を注出する注出スリット２ｃを設けた注出筒２ｂを垂設して、弁体３を嵌合可能に形成して、また、前記外筒７ｂの外側に容器本体１の側壁部に嵌合する保持筒８を垂設すると共に、該保持筒の外側に蓋体６を着脱可能に螺合する外筒壁９を形成して、更に、前記外筒壁に連接して中蓋２の密閉蓋部２ａの上面に立設する環状壁９ａを形成して、塗布体５の受け皿４を嵌合可能にした容器本体１の口頸部１ａに嵌着可能な中蓋２を構成する。
【００２０】
また、合成樹脂の射出成形あるいは金属板のプレス加工により、図３に示すように、前記塗布体５を収容して塗布可能に固定する受け皿４を、前記中蓋２に上下動自在に嵌合可能に成形して、前記受け皿の底部には、中央部に内容液の注出口となる嵌合筒４ａを垂設して、ピストン状をした弁体３内に嵌合可能に形成すると共に、底壁に一端を連接せしめて切り起こした弾性片（板バネ）４ｂを設けて、前記中蓋２の環状壁９ａの内面に沿って上下動可能に形成して、更に、前記受け皿４の周壁４ｃの内面に、塗布体５を係止する係止突起４ｄを形成する。
同じように、軟質の合成樹脂を射出成形して、有底の円筒状に形成すると共に円筒状の側壁面に断面がくの字状をした摺動片３ａを環状に形成して、前記中蓋の嵌合筒部の内周面に密着して摺動可能にしたピストン状の弁体３を成形して、前記摺動片の中央部に中蓋２の注出筒２ｃに連通可能な内容液の流出口３ｂを設けて、内溶液を注出可能に形成する。
【００２１】
続いて、スポンジやフェルト等の吸湿性を有する軟質の材料を前記受け皿４の形に合わせて打ち抜いて塗布体５を形成して、該塗布体を上記のように形成された受け皿４に押し込んで装着すると、前記受け皿の周壁４ｃの内周面に設けられた係止突起４ｄが塗布体５の外周面に係止して、受け皿４と一体になった塗布部材が形成される。
上記のように形成した受け皿４の底部に形成された嵌合筒部４ａに前記ピストン状の弁体３を嵌合せしめて一体にしたものを前記中蓋２に嵌着すると、前記ピストン状の弁体３が中蓋の前記注出筒２ｂに摺動可能に嵌合されると共に、前記受け皿４が中蓋２の環状壁９ａ内に上下動可能に嵌合されて、中空容器本体の口頸部１ａに嵌合、固定可能にした塗布体付きの中蓋が形成される。
【００２２】
そして、上記のように形成された塗布体付きの中蓋を、図２に見るように、熱可塑性合成樹脂のブロー成形により成形された胴壁部が柔軟な容器本体１の本体部分に各種の液体化粧料や薬液等の溶液を収容してから、前記中空容器の口頸部１ａに嵌合、固定して、内溶液を塗布可能にした液体塗布容器の本体を形成する。
このように形成された液体塗布容器の本体は、図１に見るように、螺着可能に形成された外蓋６を塗布体５の上に被着してから、該外蓋を回動させて中蓋２の外筒壁９に螺合せしめて密閉することにより液体塗布容器が構成される。
【００２３】
上記のようにして構成される本願発明の液体塗布容器は、それを使用するに際して、外蓋６を回動せしめて、図２に示すように中蓋２の外筒壁９から分離してから、手に持った容器本体を逆さまにして、図４に示すように、塗布体５を塗布する面に押し付けると、塗布体５が嵌着、固定された受け皿４は、押圧力により底部に設けられた弾性片４ｂが平らに変形して、前記弁体３と一緒に後退する。
【００２４】
このようにして、一体になった受け皿４と弁体３が中蓋２の注出筒２ｂの内面に沿って後退すると、注出筒２ｂの下端部に形成された注出スリット２ｃと弁体３の摺動片３ａに設けられた流出口３ｂとが連通するので、容器本体１の胴壁部１ｂが握力により押圧されると、容器本体１内の溶液は、前記注出スリット２ｃと流出口３ｂを経て嵌合筒部４ａ内へ注出されて、塗布体５に含浸される。
そこで、内容液を塗布しようとする塗布面に前記塗布体５を押し当てた状態にして、手に持った容器本体１を移動させることにより、塗布体５に含浸された内容液を塗布面に必要なだけ塗布することがてきる。
【００２５】
そして、このようにして必要とする塗布操作が終わって、容器本体を手に持ったまま塗布体を塗布面から離すと、底部に設けた弾性片４ｂの復元力により受け皿４は元の位置に押し上げられるので、中蓋２の注出筒２ｂの注出スリット２ｃと弁体３の流出口３ｂとは非連通状態になって、内溶液の注出が停止される。
そこで、容器本体１の塗布体５に外蓋６を被せてから、前記外蓋を中蓋２の外筒壁９に螺合せしめると、液体塗布容器は完全に密閉された状態になり、再び保存しておくことが可能になる。
【００２６】
本願発明は、容器本体に収容した内溶液を注出するのに、塗布体を塗布可能に保持した受け皿に嵌着して一体にしたピストン状をした弁体を、受け皿の底部に設けた弾性片（板バネ）の作用により上下動させることにより、容器本体の口頸部に嵌合して中蓋の注出スリットを開閉せしめて内溶液を注出するように構成したものであるから、塗布面に対する塗布体の押圧度を加減することにより、内溶液の注出量を調節することができて、また、不使用時に蓋体を容器本体に螺着して保存した場合に、蓋体の内面が塗布体に密着したり、塗布体を押さえ付けたりすることがないので、軟質の塗布体であっても傷めるようなこともなくて、長期の使用に耐えることができる。
【００２７】
尚、上記した実施例に於いて、塗布体を保持した受け皿を上下動させるのに、受け皿の底部を切り起こし状に形成して、板バネ状の弾性片を一体成形とした構造となしたが、本願発明は、このような構造に限定されるものでなくて、別体に形成した板バネあるいはコイルバネ等の適当な弾性部材を、塗布体を保持した受け皿の底面に設けて、弾性力により受け皿を上下動可能となして、中蓋の注出スリットを開閉せしめるような構造にすることも可能である。
また、塗布体を収容した受け皿の底部に形成した嵌合筒部に、別体に形成したピストン状の弁体３を嵌合せしめたものを、中蓋の注出筒に摺動可能に嵌合せしめて内容液を注出可能に形成したが、このような構造に代えて、ピストン状の弁体３を受け皿の底部の嵌合筒部に一体に成形したものを、中蓋の注出筒に摺動可能に嵌合せしめて内容液を注出可能に形成することも可能である。
【００２８】
【発明の効果】
本願の発明は、中空の容器本体の口頸部に、中蓋を内外筒からなる嵌合筒を嵌着せしめて固定すると共に、前記中蓋の注出筒に、塗布体を嵌着して固定した受け皿の底部の嵌合筒部に嵌合して一体にピストン状の弁体を摺動可能に嵌合せしめて密閉したので、中蓋および受け皿の支持構造が簡単で、且つ、密着性がよくて液漏れがない。
また、塗布体を、受け皿の周壁内面に設けた係止突起により固定したので、塗布体の支持構造が簡単で、安価に製造することができて、使用中に塗布体が抜け落ちないように確実に固定することができる。
更に、受け皿の底部に設けた弾性体により、受け皿を上下動させて注出口が開口するように形成したので、押圧力を加減することにより注出量を調節することができる。

BACKGROUND OF THE INVENTION
The invention of the present application is a liquid solution such as a liquid medicine such as a liquid medicine such as a hair preparation or a foundation, a liquid medicine such as a hair preparation or a foundation, or a liquid medicine such as a hair preparation or a disinfectant contained in a hollow container. It is related to liquid application containers that apply solutions, and in particular, an application member made of a soft, good liquid-absorbing material such as sponge or felt is provided on the mouth and neck of a hollow container containing various chemicals and the like. In this regard, the present invention relates to a liquid application container in which an inner solution can be easily applied simply by pressing an application member directly against a target application surface.
[0002]
[Prior art]
For liquid containers that have been used in general, open the lid of the container before use, and apply chemicals such as anti-smudge and disinfectant after absorbing them with a cotton swab or absorbent cotton, or apply a foundation or lotion. In general, liquid cosmetics such as water are applied to the skin after receiving an appropriate amount on the palm, and liquids such as water repellent and wax are generally applied after being transferred to a sponge or towel. In such a type of liquid container, it is troublesome to pour out the inner solution, and there are various problems such as extra pour out or the inner solution sticking to the hand and becoming dirty. .
[0003]
Therefore, various liquid application containers that can directly apply an inner solution poured out from a hollow container in which a solution such as a cosmetic or a chemical solution is stored are disclosed in Japanese Patent Application Laid-Open No. 11-157582 and Japanese Utility Model Laid-Open No. 62-179070. No. 7/40520 and others.
These liquid application containers can be directly applied by pouring the inner solution from the hollow container, and it is very convenient because it can be applied easily and without any trouble. By applying a spherical or hemispherical application body provided on the mouth and neck to the application surface, the liquid outlet is opened and the inner solution is poured out to adhere to the application body surface.
[0004]
However, the above-mentioned application body is formed with a low hygroscopic material such as silicon rubber or synthetic resin, so that the application efficiency is poor, and the above-mentioned liquid application container is a cosmetic such as a foundation or an anti-smudge It cannot be used for foreign solutions such as chemical solutions, and since the space between the mouth and neck and the applied body is not kept sufficiently liquid-tight, there is a risk of liquid leakage. .
Accordingly, in order to improve such problems, an application body formed of a hygroscopic and breathable sponge is provided at the spout of the mouth and neck of the container main body containing a solution such as cosmetics and chemicals, and the mouth The applicant previously described a liquid application container formed so that it can be applied by opening and closing the spout by rotating a lid that is detachably screwed to the neck, as disclosed in Japanese Utility Model Application Nos. 1-116159 and 61-61. This is proposed in Japanese Patent No. 22843.
[0005]
As shown in FIG. 5, the liquid application container shown in the above publications is formed by forming an outer lid screw portion 21 a and a sealed cylindrical screw portion 21 b on the mouth and neck of the container body 21, and the sealed cylindrical screw connection. The sealing cylinder 23 is screwed to the portion, and a water-permeable applicator 26 is stretched at the tip of the sealing cylinder screwing portion so that the content liquid can be applied.
As shown in FIG. 6, the liquid application container is provided with a spout 22 at the tip of a sealed cylindrical threaded portion 21b of the mouth and neck of the container body 21, and an annular sealing piece 22a on the outer periphery thereof. A sealing cylinder 23 is screwed into the sealing cylinder threaded portion to provide a sealed inner wall portion 23a with which the annular sealing piece 22a contacts the sealing cylinder, and a plug portion 24 and a liquid injection hole 25 are provided on the top wall portion of the sealing cylinder. A water-permeable applicator body 26 is stretched outside the liquid injection hole 25, and an outer lid body 28 having an inner lid 27 is detachably screwed onto the lid body screwing portion so as to be sealed. Formed.
[0006]
In the liquid application container formed in this manner, the outer cover body 28 is rotated to open the cover cylinder 23 so that the sealing cylinder 23 is raised to open the spout 22 and the inner solution is poured out to apply the application body 26. The inner solution impregnated in the application body can be applied directly to the application surface simply by rotating the outer lid body 28 and separating it from the container body 1. However, the structure for opening and closing the spout and the support structure for the application body are complicated, and there is room for improvement because the degree of opening cannot be adjusted.
In view of this, a liquid applicator container having a simpler support structure for the spout and applicator is proposed in Japanese Utility Model Laid-Open No. 7-2257.
[0007]
As shown in FIG. 7, the liquid application container described in the above publications has an outer lid on the mouth and neck of a hollow cylindrical container body 31 having a bottom and containing a coating liquid such as a water repellent. The inner lid 32 having an outer cylinder wall to which the screw 34 can be screwed is fitted, and the application body 33 formed in a donut shape is fitted and fixed on the upper surface of the inner lid. The body is impregnated so that it can be applied to a coated surface such as glass.
[0008]
As shown in FIG. 8, the liquid application container configured as described above has an inner lid 32 fitted on the mouth and neck portion 31a of a hollow cylindrical container body, and a sealed lid surface 32a of the inner lid. An outflow hole 39 communicating with the inside of the container body is formed in the container body, and a flat valve body 35 is disposed on the upper surface of the inner lid portion 32 so as to be movable up and down, and the outflow hole 39 is formed in a lower surface portion of the valve body. A plug portion 35a for sealing is provided so that the application body 33 is fitted on the lid surface of the inner lid 32, and is fixed by a locking projection 32b provided on the inner surface of the outer peripheral wall of the inner lid. Yes.
The outer lid 34 is detachably screwed to the inner lid 32, and the inner surface of the top plate portion of the outer lid 34 is pressed against the flat valve body 35 when the outer lid is screwed. A pressing protrusion 34 a is provided for pressing the plug portion 35 a of the flat valve body so as to plug the outflow hole 39 provided in the inner lid 32.
[0009]
