Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、挽いたコーヒー豆原料からコーヒーを入れる場合、又は紅茶の葉から紅茶を入れる場合等に使用するコーヒー又は紅茶用ドリッパーに関する。
【０００２】
【従来の技術】
従来のコーヒードリッパーは、全体が陶器、磁器、又は耐熱プラスチックで構成され、コーヒードリッパーに備えられた逆円錐台状の濾紙収納部の底には通液孔が設けられ、濾紙収納部の側方には把手部が設けられ、更に濾紙収納部の下外側には円形台の設置部が設けられていた。
このようなコーヒードリッパーの使用にあっては、カップ等の所定の容器に設置部を介してコーヒードリッパーを載せた後、濾紙収納部に漏斗状の濾紙を広げて入れ、この濾紙内に挽いたコーヒー豆を所定量入れた後、上方から熱湯を注いで容器内に抽出したコーヒー液を流下させ、コーヒーを作っていた。
しかし、濾紙収納部の底に設けられた通液孔は、常時開放状態となっているので、１つの容器内にコーヒー液を抽出したコーヒードリッパーを他の容器に移そうとする場合、コーヒーの豆原料や濾紙に含まれているコーヒー液が通液孔から雫となって漏れ出すという問題があった。
そこで、図７に示すように、逆円錐台状の濾紙収納部８０の底部分に設けられた通液孔８１に、常時は弾性的に付勢されてコーヒー液の流下を防ぐ栓８２を設けると共に、この栓８２を開くロッド部材８３を設け、しかもこのロッド部材８３の操作部８４を濾紙収納部８０の一方側に設けられた把手部８５の近傍に配置したコーヒードリッパー８６が提案されている。なお、ロッド部材８３は、濾紙収納部８０の外側に設けられたガイド部８７及び把手部８５の各開口部８８、８９をそれぞれ貫通し、濾紙収納部８０に沿って斜め方向に移動可能に支持され、ロッド部材８３の下端には栓８２が、上端には操作部８４がそれぞれ設けられ、更に、把手部８５と操作部８４との間には、栓８２を上方に付勢する弾性部材９０が設けられている。また、濾紙収納部８０の下外側には円形の設置部９１が設けられている。
これにより、個別の容器にそれぞれコーヒーを作る場合、コーヒードリッパー８６の移送中に通液孔８１からのコーヒー液の漏れを防止でき、しかも場合によっては紅茶を作ることも可能になる（例えば、特許文献１参照。）。

【発明が解決しようとする課題】
しかしながら、上記したコーヒードリッパーには、以下の問題がある。
コーヒー液の流下を行うため操作部を押圧した場合、又はコーヒー液の流下を停止するため操作部の押圧を止めた場合、ロッド部材は濾紙収納部の壁面に沿って斜め方向に移動するので、栓も通液孔に対して斜め方向に移動する。このため、栓の側部が通液孔の内側周囲と擦れ合って、通液孔が開放又は閉塞されるので、コーヒードリッパーを繰返し使用することで栓が偏摩耗し、栓により通液孔を閉塞する場合に、十分に閉塞状態を維持できなくなり、通液孔からのコーヒー液の漏れが発生する恐れがある。
ここで、斜め方向に移動しているロッド部材を、上下方向に平行移動させることで、栓を上下方向に移動させ、栓の偏摩耗を防止することも考えられるが、ロッド部材を上下方向に平行移動させるためには、ガイド部及び把手部の各開口部の大きさを現状より大きくする必要があり、ガイド部及び把手部が現状より大きくなり、コーヒードリッパーをコンパクトにできない。なお、ロッド部材が濾紙収納部の外側に露出しているため、外観性も悪い。
また、設置部の大きさは、使用する各種容器の大きさを予め考慮して設けられているため、その外径を大きくする必要があり、やはりコーヒードリッパーをコンパクトにできない。
本発明はかかる事情に鑑みてなされたもので、栓の偏摩耗を防止でき、外観性が良好で、しかもコンパクトにできるコーヒー又は紅茶用ドリッパーを提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記目的に沿う第１の発明に係るコーヒー又は紅茶用ドリッパーは、上部一端には外側に突出する把手部を備えると共に、底部分には濾過された液を流下する通液孔が設けられた実質的に逆円錐台状の濾紙収納部と、濾紙収納部の下外側に設けられた設置部と、上下動し通液孔に常時付勢される栓と、栓の開閉操作を行う操作部材とを有するコーヒー又は紅茶用ドリッパーであって、栓はテーパー状に形成された通液孔の下部口に下から上に向けてスプリングによって付勢され、しかも、操作部材は、把手部に基部があって濾紙収納部の内側斜面に近接して配置され、先部が栓の突出部に連結されて基部の押圧操作によって栓を下方に押し下げ可能なロッド部材と、基部の押圧操作によってロッド部材の先部を上下方向にガイドするガイド機構とを有する。このように、濾紙収納部の内側に配置されたロッド部材の先部に連結され、しかも通液孔の下部口に対して下から上に向けてスプリングによって付勢された栓を、ガイド機構によって上下方向に移動できるので、栓の斜め方向への移動を防止できる。
【０００６】
ここで、第１の発明に係るコーヒー又は紅茶用ドリッパーにおいて、濾紙収納部の内側の下部中央には濾紙を載せる載置台が設けられ、載置台は側部に対向する垂直ガイド孔が設けられた筒体と筒体の上部にある円形板とを有し、筒体内に栓の突出部が嵌入し、垂直ガイド孔を挿通するロッド部材の先部ごとスプリングによって上方に付勢され、しかも、ガイド機構はロッド部材の先部が挿通する垂直ガイド孔と、垂直ガイド孔に挿通する手前位置のロッド部材に設けられ、ロッド部材の基部を押し下げた場合にロッド部材の先部が垂直ガイド孔に更に深く嵌入するのを防止するストッパーとを有してなることが好ましい。このように、載置台の筒体の側部に対向する垂直ガイド孔を設け、この各垂直ガイド孔にロッド部材の先部が挿通されているので、ロッド部材を垂直ガイド孔に沿って上下方向に移動させることができる。また、垂直ガイド孔に挿通する手前位置のロッド部材にストッパーが設けられているので、ロッド部材の基部の押し下げ時において、例えロッド部材が斜め方向に移動し、ロッド部材の先部が垂直ガイド孔に更に深く嵌入しようとしても、ストッパーが垂直ガイド孔を貫通することなく筒体に当接して下降するため、ロッド部材の先部に連結される栓も通液孔の下方へ真直ぐに下降する。
【０００７】
第１の発明に係るコーヒー又は紅茶用ドリッパーにおいて、把手部には、押し下げたロッド部材の基部をその状態で固定するロック機構が設けられていることが好ましい。これにより、ロッド部材の基部を指で押圧し続けることなく、基部の押圧状態を維持できる。
第１の発明に係るコーヒー又は紅茶用ドリッパーにおいて、設置部は、濾紙収納部の下部周囲に設けられた円形台と、円形台の周辺部に基部が取付けられて水平方向に開閉可能に設けられた３本以上の脚と、開いた状態のそれぞれの脚を所定位置で係止する保持部材とを有することが好ましい。このように、設置部の円形台の周辺部には、水平方向に開閉可能な３本以上の脚が設けられているので、容器の大きさに応じて水平方向に各脚を開き、濾紙収納部を容器の上に脚を介して載せることができる。また、保持部材により、開いた状態の各脚を所定位置で係止できるので、各脚のぐらつきを防止できる。
【０００８】
前記目的に沿う第２の発明に係るコーヒー又は紅茶用ドリッパーは、上部一端には外側に突出する把手部を備えると共に、底部分には濾過された液を流下する通液孔が設けられた実質的に逆円錐台状の濾紙収納部と、濾紙収納部の下外側に設けられた設置部と、上下動し通液孔に常時付勢される栓と、栓の開閉操作を行う操作部材とを有するコーヒー又は紅茶用ドリッパーであって、設置部は、濾紙収納部の下部周囲に設けられた円形台と、円形台の周辺部に水平方向に開閉可能に設けられた３本以上の脚と、開いた状態のそれぞれの脚を所定位置で係止する保持部材とを有する。このように、設置部の円形台の周辺部には、水平方向に開閉可能な３本以上の脚が設けられているので、容器の大きさに応じて水平方向に各脚を開き、濾紙収納部を容器の上に脚を介して載せることができる。また、保持部材により、開いた状態の各脚を所定位置で係止できるので、各脚のぐらつきを防止できる。
【０００９】
ここで、第１、第２の発明に係るコーヒー又は紅茶用ドリッパーにおいて、それぞれの脚は同一形状となって、その基部が円形台の同一半径位置の円周上に均等配置されたピンに回動可能に配置され、閉じた状態では底面視して円形台の最外周円内に納まることが好ましい。このように、各脚の形状を同一形状にするので、製造コストを低減できる。また、脚の基部を円形台にピンを介して回動可能に配置するので、各脚を簡単な構成で開閉できる。そして、各脚は、閉じた状態では円形台の最外周円内に納まるので、コーヒー又は紅茶用ドリッパーの使用時以外は、コンパクトにできる。
第１、第２の発明に係るコーヒー又は紅茶用ドリッパーにおいて、それぞれの脚の先部は下方に突出する接地部を備えていることが好ましい。このように、各脚の先部に、下方に突出する接地部を設けるので、容器の上に載せたコーヒー又は紅茶用ドリッパーが、容器の上からずれ落ちることを防止できる。
【００１０】
第１、第２の発明に係るコーヒー又は紅茶用ドリッパーにおいて、濾紙収納部の下側には、設置部を下側から覆って固定する受け台が設けられていることが好ましい。これにより、受け台を、例えば、設置部のキャップとして利用したり、またコーヒー又は紅茶用ドリッパーの使用前及び使用後の置き場所としても利用できる。
第１、第２の発明に係るコーヒー又は紅茶用ドリッパーにおいて、濾紙収納部の下部周囲に設けられた円形台の外側周辺部には凹部が設けられ、受け台の内側には受け台の軸心に向かって突出し凹部を挿通可能な凸部が設けられ、円形台の凹部に凸部を挿通した後、円形台を回動させ、受け台内に設置部を収納した状態を維持することが好ましい。このように、簡単な構成で、設置部を受け台内に収納した状態を維持できる。
【００１１】
【発明の実施の形態】
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
ここに、図１は本発明の一実施の形態に係るコーヒー又は紅茶用ドリッパーの説明図、図２は同ドリッパーの斜視図、図３（Ａ）〜（Ｄ）はそれぞれ同ドリッパーの載置台、栓、ロッド部材、ロック機構の説明図、図４は同ドリッパーの底面図、図５は同ドリッパーの受け台の説明図、図６は同ドリッパーの使用状態の説明図である。
【００１２】
図１、図２に示すように、本発明の一実施の形態に係るコーヒー又は紅茶用ドリッパー（以下、単にドリッパーとも言う）１０は、上部一端に外側に突出する把手部１１を備えると共に、底部分に濾過された液を流下する通液孔１２が設けられた実質的に逆円錐台状の濾紙収納部１３と、濾紙収納部１３の下外側に設けられた設置部１４と、上下動し通液孔１２に常時付勢される栓１５と、栓１５の開閉操作を行う操作部材１６とを有している。なお、このドリッパー１０の材質は耐熱性を有するプラスチックである。以下、詳しく説明する。
【００１３】
濾紙収納部１３に設けられた把手部１１は、濾紙収納部１３と同一の材質で構成され、例えば１〜２ｃｍの幅を備え、しかも側面視して環状となった把手本体１７と、濾紙収納部１３の上端面と同一平面上に設けられ、濾紙収納部１３と把手本体１７とを接続する水平部１８とを有している。ここで、把手本体１７の形状は、水平部１８を備えたコ字状や、逆Ｌ字状としてもよい。なお、この把手部１１は、濾紙収納部１３と一体的に製造してもよく、また、把手部１１と濾紙収納部１３とを個別に製造して接合してもよい。
【００１４】
濾紙収納部１３には、濾紙収納部１３と同一の材質で構成された蓋１９が、把手部１１と対向する側に設けられた折り曲げ可能な接続部２０を介して設けられている。この蓋１９は円板状（円盤状）となっており、操作部材１６に備えられたロッド部材２１と接触しないように、外側に開口した切欠き部２２が設けれられている。なお、濾紙収納部１３、蓋１９、及び濾紙収納部１３と蓋１９とを接続する接続部２０を一体的に製造することも、また個別に製造して接合することも可能である。そして、蓋１９の形状は、中央部が外側へ膨らんだ部分球状とすることも可能である。更に、濾紙収納部１３及び蓋１９に係合部材を設けることで、濾紙収納部１３に蓋１９をした状態を維持することもできる。
これにより、濾紙収納部１３を蓋１９で塞ぐことができるので、例えば濾紙収納部１３内に紅茶の葉を入れた後お湯を注ぎ、濾紙収納部１３内で蒸らすことができる。
【００１５】
図１、図２、図３（Ａ）に示すように、濾紙収納部１３の内側の下部中央には、濾紙２３を載せる載置台２４が設けられている。この載置台２４は、側部に対向する垂直ガイド孔２５が設けられた筒体２６と、筒体２６の上部に装着され、中央部に貫通孔を備えた円形板２７とを有している。筒体２６の側部で、垂直ガイド孔２５と異なる位置には、濾紙収納部１３内の液体を通液孔１２に流下させるための２つの開口部２８が設けられている。
円形板２７の下側には、底面視して環状となった軸心を同じとする２つの突出部２９、３０が設けられ、この突出部２９と突出部３０との間に溝部３１が形成されている。なお、突出部２９の外径は筒体２６の内径と実質的に同一で、また突出部３０の内径は筒体２６の外径と実質的に同一である。
これにより、円形板２７の溝部３１を筒体２６の上端部に上方から嵌め込むことで、筒体２６の上端部を溝部３１に嵌入させ、円形板２７を筒体２６の上部で確実に支持し、固定できる。ここで、円形板の下側に突出部２９を設けることなく、突出部３０のみを設け、かつ円形板の貫通孔の内径を筒体２６の内径と同じとすることで、円形板を筒体２６の上端部に上方から嵌め込み、筒体２６の上端に円形板を当接させ、筒体２６に円形板を固定することもできる。
【００１６】
なお、筒体２６に設けた垂直ガイド孔２５及び開口部２８は、筒体の上方に開放させてもよい。このようにしても、筒体の上端部には円形板２７が装着されるので、筒体の上側が筒体の外側周囲に開くことを防止できる。
また、濾紙収納部１３内の液体は、筒体２６の各開口部２８から通液孔１２に流下するので、円形板２７に貫通孔を形成することなく、円板状とすることも可能である。これにより、濾紙２３を円形板上に安定に載置できる。
この載置台２４は、濾紙収納部１３と一体的に製造してもよく、また、載置台２４と濾紙収納部１３とを個別に製造した後接合したり、設置台２４と濾紙収納部１３に雄ねじ、雌ねじをそれぞれ設け、取付けることも可能である。
【００１７】
筒体２６の内部には、耐食性を有するステンレスで構成され、自由状態では伸びた状態にある例えば、圧縮コイル（つる巻）ばね、円錐コイルばね等からなるスプリング３２が配置されている。なお、このスプリング３２は、その下端が通液孔１２を構成する段差部３３上に固定されている。また、筒体２６の下方、即ち濾紙収納部１３の底部には通液孔１２が設けられ、通液孔１２の下部にはテーパー状の下部口３４が形成されている。
図１、図２、図３（Ｂ）に示すように、この通液孔１２の下部口３４には、栓１５の下部に設けられ、ゴム又は弾力性を有するプラスチックからなり、実質的に半球状となった栓本体３５が、その曲面を当接可能に配置されている。また、栓本体３５には、栓本体３５の上方に突出した棒状となった栓１５の突出部３６が設けられ、この突出部３６は筒体２６の軸心に合わせてスプリング３２内に嵌入し、スプリング３２の上方に突出した状態で配置されている。突出部３６の上側には、ロッド部材２１に設けられ、各垂直ガイド孔２５を挿通してスプリング３２の上端に配置される水平状態の先部３７が、貫通して連結可能となる貫通孔３８が設けられている。
これにより、スプリング３２が自由状態では、スプリング３２により、栓１５がロッド部材２１の先部３７ごと通液孔１２の下部口３４に下から上に向けて付勢される。
【００１８】
図１、図２、図３（Ｃ）に示すように、ロッド部材２１は、ステンレス製の棒材を曲げることで構成され、濾紙収納部１３の内側斜面に沿って近接して配置される傾斜部３９を備えており、先部３７と傾斜部３９とのなす角が、例えば１００〜１３０度の範囲になっている。垂直ガイド孔２５に挿通する手前位置のロッド部材２１の先部３７には、垂直ガイド孔２５の開口幅より大きなストッパー４０が設けられている。なお、ロッド部材２１は、実質的に逆Ｌ字状となって把手部１１に設置される基部４１を備えており、この基部４１を押し下げた場合には、垂直ガイド孔２５に沿って下降するロッド部材２１の先部３７が、垂直ガイド孔２５から筒体２６内に更に深く嵌入するのをストッパー４０によって防止できる。
この垂直ガイド孔２５及びストッパー４０は、ロッド部材２１の基部４１の押圧操作によって、ロッド部材２１の先部３７を上下方向にガイドするガイド機構を構成している。なお、このガイド機構は、操作部材１６に含まれる。
【００１９】
ロッド部材２１の基部４１は、把手部１１に設けられたロック機構４２によって、押し下げた状態で固定できる。
図１、図２、図３（Ｄ）に示すように、ロック機構４２は、把手部１１の基部上方に設けられ逆Ｌ字状となった固定部４３と、把手部１１の水平部１８中央に設けられた開口部４４に挿通され、上下方向に移動可能な操作ボタン４５とを有している。この操作ボタン４５の高さ方向の中央部上側には、固定部４３に係止可能な突出部４６が設けられ、この突出部４６の上方には、操作ボタン４５を水平方向に貫通し、ロッド部材２１の基部４１の水平部分を移動可能に挿通する貫通孔４７が設けられている。また、ロッド部材２１の基部４１の垂直部分は、把手部１１の水平部１８に設けられた貫通孔４８に挿通され、基部４１から操作ボタン４５が外れること防止すると共に、ロッド部材２１が上下方向へ移動するようにガイドしている。
なお、固定部４３及び突出部４６の形状は、それぞれ鉤状とすることも可能である。また、固定部４３を把手部１１の水平部１８の把手本体１７側に、突出部４６を操作ボタン４５の把手本体１７側にそれぞれ設けることも可能である。
【００２０】
これにより、栓１５を下降させる場合においては、操作ボタン４５を指で押圧した状態で、固定部４３に突出部４６が係合するように、操作ボタン４５を濾紙収納部１３側へ移動させて係合させる。これにより、操作ボタン４５の押圧状態を維持でき、スプリング３２を圧縮状態に維持して下部口３４を開放状態にできる。また、下部口３４を栓１５で閉塞する場合には、操作ボタン４５を押圧し、固定部４３から突出部４６が外れるように操作ボタン４５を把手本体１７側へ移動させることで、操作ボタン４５を自由状態にし、スプリング３２を自由状態にして下部口３４を閉塞状態にできる。
【００２１】
図１、図２、図４に示すように、設置部１４は、濾紙収納部１３の下部周囲に設けられた円形台４９と、円形台４９の裏側周辺部に基部が取付けられて水平方向に開閉可能に設けられた４本の脚５０と、開いた状態のそれぞれの脚５０を所定位置で係止する保持部材５１とを有する。
各脚５０は、濾紙収納部１３の底部下側に通液孔１２を囲むように設けられた液体の飛散防止材５２に対して湾曲し、その先部が下方に突出する接地部５３を備え、しかも脚５０の基部に貫通孔５４を設けた同一形状となっている。また、円形台４９裏側の同一半径位置の円周上には、下端部が半球状となった係止部５５を備えたピン５６が、円形台４９の軸心を中心として９０度ごとに均等配置されている。なお、ピン５６のピン本体５７の直径は、脚５０の基部に設けられた貫通孔５４の内径より例えば１ｍｍ程度小さく、係止部５５の直径は、貫通孔５４の内径より、例えば１ｍｍ程度大きくなっている。
これにより、製造時には、貫通孔５４をピン５６の係止部５５に押込むことで、ピン５６に各脚５０を取付けることができ、取付け後は、脚５０をピン５６に対して回動可能に配置できる。
【００２２】
また、円形台４９の裏側の各ピン５６の周辺部には、下方に突出した保持部材５１が、各ピン５６を中心として等角度（例えば、２０〜５０度）に３個設けられている。この保持部材５１の位置は、脚５０を段階的に開いた状態で維持できる位置になっており、飛散防止材５２に最も近い位置にある保持部材５１は、脚５０を閉じた状態に維持できる位置に配置されている。なお、脚５０は閉じた状態では底面視して円形台４９の最外周円内に納まる長さであるため、設置部１４をコンパクトにできる。
このように、設置部１４の円形台４９の外径を、コーヒー液を入れる容器５８の内径より小さくし、濾紙収納部１３を各脚５０を介して容器５８の上に載せることができるので、容器５８内部に注がれた例えばコーヒーの量を目視しながら、濾紙収納部１３内にお湯を注ぐことができる。
【００２３】
図５に示すように、濾紙収納部１３の下側には、設置部１４を下側から覆って固定する受け台５９が設けられている。この受け台５９は、濾紙収納部１３と同一の材質で構成され、その形状は、断面円形の容器状となっている。この受け台５９の内径Ｄは、円形台４９の外径より例えば５〜１０ｍｍ程度大きくなっている。
円形台４９の外側周辺部には、３つの凹部６０が異なる位置、例えば円形台４９の軸心を中心として等角度（１２０度）ごとにそれぞれ設けられている。この凹部６０の形状は、実質的に矩形状になっているが、円形台４９の外側に開口していればよく、例えば、半円形、半楕円形、半卵形、三角形等にすることも可能である。
【００２４】
受け台５９の内側には、受け台５９の軸心に向かって突出し凹部６０を挿通可能な凸部６１が設けられている。なお、凸部６１下面と受け台５９の底部６２上面との高さ方向の間隔ｄは、円形台４９の上端から飛散防止材５２の下端までの距離より、例えば２〜５ｍｍ大きくなっている。また、凸部６１の先端で形成される円の直径Ｄ１は、円形台４９の外径より小さくなっている。
これにより、円形台４９の凹部６０に凸部６１を挿通し、飛散防止材５２の下端を受け台５９の内側底面に当接させた後、平面視して凹部６０が凸部６１と異なる位置になるように円形台４９を受け台５９に対して回動させることで、円形台４９に受け台５９を取付け、受け台５９内に設置部１４を収納した状態を維持できる。
【００２５】
続いて、本発明の一実施の形態に係るコーヒー又は紅茶用ドリッパー１０の使用方法について、挽いたコーヒー豆原料からコーヒーを入れる場合、紅茶の葉から紅茶を入れる場合について、それぞれ説明する。
まず、設置部１４から受け台５９を取外し、容器５８の大きさに応じて設置部１４の各脚５０を開き、ドリッパー１０を容器５８の上に設置部１４を介して載せる（図１参照）。この状態で、上方から濾紙収納部１３内に濾紙２３を入れ、濾紙２３の底部が載置台２４の上端に載置されるように配置する（図２参照）。なお、このとき、操作ボタン４５は押圧下降されておらず、スプリング３２が伸びた状態（自由状態）を維持するため、通液孔１２の下部口３４は栓１５の栓本体３５により閉塞状態に維持される。
【００２６】
この後、コーヒー豆を挽いたコーヒー原料を濾紙２３内に入れて、上方から熱湯を注いだ後、蓋１９を閉めてコーヒー液を作る。数秒経過した（コーヒー液ができた）後、ドリッパー１０の通液孔１２を、開いた状態に維持させるため、操作ボタン４５を押圧下降する。これにより、ロッド部材２１は略垂直方向に下降するため、栓１５は、通液孔１２の下方に略垂直方向に下降し、通液孔１２が開放状態になる。そして、操作ボタン４５を押圧したまま濾紙収納部１３側へ移動させることで、操作ボタン４５の突出部４６を、固定部４３に係止する。
これにより、操作ボタン４５は下降状態が維持され、スプリング３２が圧縮状態を維持するので、栓１５が通液孔１２の下部口３４とは隙間を有して配置される状態が維持される（図６参照）。これにより、濾過されたコーヒー液が、円形板２７の貫通孔及び筒体２６の開口部２８を介して通液孔１２へ流下し、容器５８の中へ流れ込む。従って、操作ボタン４５を指で押圧し続けることなく、通液孔１２が開いた状態を維持できる。よって、多くのコーヒー液を作る場合は、濾紙２３内のお湯の量を見ながら、更にお湯を注ぎ続けることで、ドリッパー１０からのコーヒー液の流下を連続的に行うことができるので、作業性が良好である。
【００２７】
なお、容器５８へのコーヒー液の流下が終了した場合、又は容器５８へのコーヒー液の流下を停止する場合は、操作ボタン４５の突出部４６が固定部４３から外れる位置まで、操作ボタン４５を押圧しながら濾紙収納部１３と反対側にずらすことで、操作ボタン４５の押圧下降状態が解除される。これにより、スプリング３２に加えられていた力が無くなり、スプリング３２は自由状態になる。従って、栓１５は通液孔１２に対して略垂直方向に上昇し、栓本体３５が下部口３４に当接して、通液孔１２の閉塞状態が維持される（図１参照）。従って、コーヒーの原料豆や濾紙２３に含まれているコーヒー液の通液孔１２からの漏れ出しを、片手による押圧操作のみで容易に防ぐことができるので、作業性及び操作性が良好になる。
なお、ドリッパー１０の使用が終了した後は、受け台５９にドリッパー１０を載置して放置できるので、例えば、栓１５や飛散防止材５２に付着したコーヒー液の雫が、台の上に付着することを防止できる。
【００２８】
次に、紅茶の葉から紅茶を入れる場合について説明する。
まず、ドリッパー１０を受け台５９に載置した状態で、ドリッパー１０の濾紙収納部１３内に濾紙２３を入れ、濾紙２３の底部が載置台２４の上端に配置されるように配置する（図２参照）。なお、このとき、操作ボタン４５は押圧下降されておらず、スプリング３２が伸びた状態（自由状態）にあるため、通液孔１２の下部口３４は栓１５の栓本体３５により閉塞状態が維持されている。この後、紅茶の葉を濾紙２３内に入れ、上方から熱湯を注ぎ、濾紙収納部１３に蓋１９をした後、紅茶を抽出するため所定時間（例えば、１０秒から３分程度）放置する。

紅茶ができた後、設置部１４から受け台５９を取外し、ドリッパー１０を容器５８の上に持って行き、操作ボタン４５を指で押圧することで、容器５８に紅茶を流下させる。なお、容器５８に流下させる量は多くないため、容器５８に所定量紅茶を流下させた後は、操作ボタン４５を押圧していた指を離すことで、通液孔１２を栓１５により閉塞し、紅茶の流下を停止する。この動作を繰返すことで、通液孔１２から雫を漏らすことなく、複数の容器５８に紅茶を流下させることが可能となる。
なお、ドリッパー１０の使用が終了した後は、受け台５９にドリッパー１０を載置して放置できるので、例えば、栓１５や飛散防止材５２に付着した紅茶の雫が、台の上に付着することを防止できる。

In the periphery of each pin 56 on the back side of the circular base 49, three holding members 51 protruding downward are provided at equal angles (for example, 20 to 50 degrees) around each pin 56. The position of the holding member 51 is a position where the leg 50 can be maintained in an open state in a stepwise manner, and the holding member 51 closest to the shatterproof member 52 can maintain the leg 50 in a closed state. Is located in the position. In addition, since the leg 50 has a length that fits within the outermost circumference circle of the circular base 49 when viewed from the bottom in the closed state, the installation portion 14 can be made compact.
As described above, the outer diameter of the circular base 49 of the installation portion 14 is smaller than the inner diameter of the container 58 for storing the coffee liquid, and the filter paper storage portion 13 can be placed on the container 58 via each leg 50. Hot water can be poured into the filter paper storage unit 13 while visually checking the amount of, for example, coffee poured into the container 58.
[0023]
As shown in FIG. 5, a receiving stand 59 is provided below the filter paper storage unit 13 to cover and fix the installation unit 14 from below. The pedestal 59 is made of the same material as the filter paper storage unit 13 and has a container shape with a circular cross section. The inner diameter D of the receiving table 59 is larger than the outer diameter of the circular table 49 by, for example, about 5 to 10 mm.
In the outer peripheral portion of the circular table 49, three concave portions 60 are provided at different positions, for example, at equal angles (120 degrees) about the axis of the circular table 49, respectively. The shape of the concave portion 60 is substantially rectangular, but it is sufficient that the concave portion 60 is open outside the circular base 49, and for example, may be semicircular, semielliptical, semi-oval, triangular, or the like.

Thereafter, the coffee raw material obtained by grinding the coffee beans is put into the filter paper 23, hot water is poured from above, and the lid 19 is closed to make a coffee liquid. After a lapse of several seconds (the coffee liquid is formed), the operation button 45 is pressed down to keep the liquid passage hole 12 of the dripper 10 in an open state. As a result, the rod member 21 descends in a substantially vertical direction, so that the stopper 15 descends in a substantially vertical direction below the liquid passage hole 12, and the liquid passage hole 12 is opened. Then, by moving the operation button 45 toward the filter paper storage unit 13 while pressing the operation button 45, the protrusion 46 of the operation button 45 is locked to the fixing unit 43.
Accordingly, the operation button 45 is maintained in the lowered state, and the spring 32 is maintained in the compressed state, so that the state in which the stopper 15 is arranged with a gap from the lower port 34 of the liquid passage hole 12 is maintained ( See FIG. 6). Thereby, the filtered coffee liquid flows down to the liquid passage hole 12 through the through hole of the circular plate 27 and the opening 28 of the cylindrical body 26, and flows into the container 58. Therefore, the state where the liquid passage hole 12 is opened can be maintained without continuously pressing the operation button 45 with a finger. Therefore, when making a large amount of coffee liquid, by continuing to pour hot water while checking the amount of hot water in the filter paper 23, it is possible to continuously flow the coffee liquid from the dripper 10, so that workability is improved. Is good.
[0027]
When the flow of the coffee liquid into the container 58 is completed or when the flow of the coffee liquid into the container 58 is stopped, the operation button 45 is moved to a position where the protruding portion 46 of the operation button 45 comes off the fixing portion 43. By depressing and shifting to the opposite side of the filter paper storage unit 13, the depressed state of the operation button 45 is released. As a result, the force applied to the spring 32 is eliminated, and the spring 32 is in a free state. Accordingly, the stopper 15 rises in a direction substantially perpendicular to the liquid passage hole 12, the stopper body 35 contacts the lower port 34, and the closed state of the liquid passage hole 12 is maintained (see FIG. 1). Therefore, leakage of the coffee liquid contained in the coffee raw material beans and the filter paper 23 from the liquid passage hole 12 can be easily prevented by only one-hand pressing operation, thereby improving workability and operability. .
After the use of the dripper 10 is completed, the dripper 10 can be placed on the cradle 59 and allowed to stand, so that, for example, drops of coffee liquid adhering to the stopper 15 or the scattering prevention material 52 adhere to the pedestal. Can be prevented.

Next, a case where black tea is introduced from the leaves of black tea will be described.
First, with the dripper 10 placed on the receiving table 59, the filter paper 23 is put into the filter paper storage unit 13 of the dripper 10, and the filter paper 23 is arranged such that the bottom of the filter paper 23 is disposed at the upper end of the mounting table 24 (FIG. 2). reference). At this time, since the operation button 45 is not pressed down and the spring 32 is in an extended state (free state), the lower port 34 of the liquid passage hole 12 is kept closed by the stopper body 35 of the stopper 15. Have been. After that, the leaves of the black tea are put into the filter paper 23, hot water is poured from above, the cover 19 is placed on the filter paper storage unit 13, and then left for a predetermined time (eg, about 10 seconds to 3 minutes) to extract the black tea.
[0029]
After the tea is made, the cradle 59 is removed from the installation section 14, the dripper 10 is brought over the container 58, and the operation button 45 is pressed with a finger to cause the tea to flow down into the container 58. Since the amount of tea flowing down into the container 58 is not large, after flowing a predetermined amount of black tea into the container 58, the finger that has pressed the operation button 45 is released to close the liquid passage hole 12 with the stopper 15. Stop the flow of black tea. By repeating this operation, it is possible to cause the black tea to flow down to the plurality of containers 58 without leaking drops from the liquid passage holes 12.
After the use of the dripper 10 is completed, the dripper 10 can be placed on the cradle 59 and allowed to stand, so that, for example, drops of black tea adhering to the stopper 15 or the scattering prevention material 52 adhere to the table. Can be prevented.
