【発明の属する技術分野】
本発明は、支持具付抽出バッグ及びその製造用シート複合体に関するものである。更に詳しく述べるならば、本発明は、抽出バッグを、抽出容器上に安定して載置し、簡単な操作で抽出バッグを開口し、安全に抽出を行うことができる支持具付抽出バッグ、及びこの支持具付抽出バッグを、容易にかつ効率よく製造することができる支持具付抽出バッグ製造用シート複合体に関するものである。
【０００２】
【従来の技術】
実公昭６０−７６２３号及び特開平８−３３５７２号には、フィルター製袋体と、厚紙製ホルダーとを一体化し、ホルダーを折り曲げて支持具を組み立て、袋体内の被抽出物に抽出を施すことが可能な抽出用具が開示されている。
【０００３】
また、特開平１１−２８５４４３号には、厚質シートの中心線中央部に中心孔を設け、この中央部の中心孔の外側に、この中心線を上方に折曲げることを可能にする押罫線を設け、中心孔の両外側部に、中心線と直交し、前記押罫線を介して、下方向に折り曲げ可能な１対の支持片を設け、前記中心孔の全周縁裏側に、濾紙からなる袋体の上縁部を接着して形成したコーヒー等飲料の簡易抽出用具が開示されている。
【０００４】
しかしながら従来の支持具付抽出バッグの製造には、先ず袋体を製造し、これを支持具に組み合わせて固着し、この袋体に被抽出材料を充填し、充填口を封止するという別々の３工程を必要としていた。そこで、上記３工程を単一工程において連続的に実施して製造できる新しい支持具付抽出バッグの出現が強く望まれていた。

【発明の実施の形態】
本発明の支持具付抽出バッグ（１）の支持具を形成する支持部材の構成は下記の通りである。
図１は支持部材付抽出バッグを、支持部材の横手中心軸の両側に展開したときの平面形状を示すものであって、支持部材１は、その横手中心線２の両側（図１においては上下両側）において、対称形をなす２半部１ａ，１ｂからなり、この２半部１ａ，１ｂは、横手中心線２において互いに連続している。
【０００９】
横手中心線２を水平方向におき、この横手中心線２が、各半部の上端線をなすように、支持部材１を見たとき、
（１）支持部材１の半部１ａ，１ｂは、その上端縁（すなわち横手中心線２）において互いに連続する頭部３ａ，３ｂと、頭部３ａ，３ｂに連続している脚部４ａ，４ｂとを有している。互に連続する頭部３ａ，３ｂを併せて連続頭部３と記す。
（２）支持部材１の下には、袋本体の展開シート材料５が配置されていて、両者の横手中心軸２、及び長手中心軸６は互に重なり合っている。
【００１０】
図１において、支持部材１の連続頭部３の中央部分には四辺形状接着線域７が形成されていて、これは例えば、横手中心軸２にほぼ平行に、互に離間している２辺８ａ，８ｂと、長手中心軸６にほぼ平行に、互に離間している２辺、９ａ，９ｂにより四辺形状に形成されている。図１において接着線域７は、連続線状に形成されているが、これは不連続線状（破線状）に形成されていてもよい。この四辺形状連続又は不連続接着線域７において、支持部材１と袋本体用シート材料５とが接着されている。四辺形状接着線域７を形成する横辺８ａ，８ｂと縦辺９ａ，９ｂとは、図１に示されているように、ほゞ直角をなして連続していてもよく、その連結角度が丸められていてもよく、或は、抽出シートの拡開操作に支障を生じない限りわずかに離間していてもよい。
【００１１】
図１において、支持部材１の四辺形状連続又は不連続接着線域７の内側に支持部材拡開部１０が形成されている。この拡開部１０には、横手中心軸２にほぼ平行に、横手接着辺域８ａ，８ｂに近接して形成された横手切り込み線１１ａ，１１ｂと、この横手切り込み線１１ａ，１１ｂの左右両端から、横手中心線に向って伸び出している長手左右切り込み線１２ａ−１，１２ａ−２，１２ｂ−１，１２ｂ−２が形成されている。これらの長手左右切り込み線１２ａ−１〜１２ｂ−２はそれぞれ、横手切り込み線１１ａ，１１ｂの左右端に、ほぼ直角をなして形成されていてもよく、或は図１に示されているように、曲線をなして丸められていてもよい。前記横手切り込み線及び長手左右切り込み線には、必要により、切断容易な連続部が形成されていてもよい。
【００１２】
支持部材拡開部１０の横手切り込み線１１ａ，１１ｂのほゞ中点の間には、横手中心線と交差する長手方向中央切り込み線１３（連続切り込み線であってもよく、又は不連続切り込み線であってもよい）が形成されている。この長手方向中央切り込み線１３の両末端は、横手切り込み線１１ａ，１１ｂのほぼ中央部に直接連続している連続切り込み線であってもよく、又は、不連続切り込み線であってもよく、或は、図１に示されているように、連続切り込み線部と、切断容易なミシン目又は不連続切り込み線部１３ａ，１３ｂが形成されていてもよい。
【００１３】
図１において、長手左右切り込み線１２ａ−１，１２ｂ−１及び１２ａ−２，１２ｂ−２のそれぞれの互に対向する末端点の中間の区間は、切断されることなく連続していて左右連続部１４ａ，１４ｂが形成されている。
【００１４】
図１において、支持部材１の両脚部４ａ，４ｂの先端の中央部分に外側に向って伸び出ている中央係合突起部１５ａ，１５ｂが形成されている。両脚部４ａ，４ｂの先端部の左右両端部には、外側に向って伸び出ている左右係合突起部１６ａ−１，１６ａ−２，１６ｂ−１，１６ｂ−２が形成されていることが好ましい。この場合、中央係合突起部と左右係合突起部の間に左右係合凹部１７ａ−１，１７ａ−２，１７ｂ−１，１７ｂ−２が形成され、支持部材を抽出容器上に載置するとき、この凹部に抽出容器の開口上縁部を差し込み、これを中央係合突起部と左右係合突起部の間に係合保持することができ、それによって抽出バッグを抽出容器上に安定に載置保持することができる。
【００１５】
図１において、支持部材拡開部１０の、横手中心線２と、長手中心線６により分画される４個の分画部は、それぞれ１個以上の拡開部接着域１８ａ−１，１８ａ−２，１８ｂ−１，１８ｂ−２により袋本体の展開シート材料５に接着されている。また、支持部材、脚部４ａ，４ｂの各々はそれに形成された１個以上の脚部接着域１９ａ，１９ｂにより袋本体展開シート材料５に接着されている。
また支持部材拡開部１０の左右両外側には、折り込み線（ミシン目、又は押圧線）２０−１，２０−２が形成されていてもよく、この場合、支持具付抽出バッグを拡開するとき、折り込み線２０−１，２０−２の外側を内側に押し込むことによって支持部材を拡開状態に固定することができる。
【００１６】
支持部材の拡開部に形成される切り込み線の形状及び切り裂き用ミシン目、不連続切り込み線の有無は、図１の態様の他に、例えば、図２−（Ａ）に示されているように、長手方向中央切り込み線１３が、横手切り込み線１１ａ，１１ｂに直接連続し、切り裂き用ミシン目又は不連続切り込み線部がなくてもよく、及び／又は長手左右切り込み線１２ａ−１〜１２ｂ−２のそれぞれが、図２−（Ａ）に示されているように横手切り込み線１１ａ，１１ｂにほゞ直角をなして連続していてもよく、両者の接続部は、図２−（Ａ）に示されているように丸められていてもよく、或は丸められていなくてもよい。また、連続部１４ａ，１４ｂには、図１及び図２−（Ａ）に示されているように、折り曲げ用ミシン目が形成されていてもよく、又は折り曲げ用押圧線が形成されていてもよく、或は連続部１４ａ，１４ｂにおける折り曲げが可能であれば、折り曲げ用ミシン目及び押圧線が形成されていなくてもよい。
【００１７】
図２−（Ｂ）に示されている支持部材拡開部１０において、横手切り込み線１１ａ，１１ｂのほゞ中央部分を結ぶように長手方向中央切り欠き部１３Ａが形成されている。この中央切り欠き部１３Ａは支持部材と袋本体とからなる支持具付き抽出バッグ（１）が形成され、袋本体内に被抽出材料が収容封止された後、この長手方向中央切り欠き部から、その内側の袋本体（被抽出材料収容）の状態を観察することができる。
図２−（Ｃ）に示されている支持部材拡開部１０においては、長手方向中央切り欠き部１３Ｂが、図２−（Ｂ）の長手方向中央切り欠き部１３Ａよりも広い幅をもって形成されており、図２−（Ｄ）に示されている支持部拡開部１０において、長手方向中央切り欠き部１３Ｃは中央部において狭く、横手切り込み線１１ａ，１１ｂに近づくにつれて広くなる形状、例えばＸ字状輪郭を有しており、図２−（Ｅ）に示されている支持部拡開部１０において、長手方向中央切り欠き部１３Ｄは、中央部において広く、横手切り込み線１１ａ，１１ｂに連続する部分において狭い形状例えば壺状輪郭を有している。本発明の抽出バッグ（１）において、支持部材拡開部１０の長手方向中央切り欠き部は、支持部材拡開部の作用効果を達成し得る限り、上記図２−（Ｂ）〜（Ｅ）に示した例に拘らず、他の適宜の形状に形成することができる。
【００１８】
図３には、図１において、支持部材１と重ね合わされた袋本体を展開したとき、シート材料５に形成される引き裂き用ミシン目又は不連続切り込み線（以下切り裂き用ミシン目と記す）の一例が示されている。この切り裂き用ミシン目は、図３に示されているように、横手中心線２に平行な、互に離間した横手ミシン目２１ａ，２１ｂと、その左右両端から横手中心線に向って伸びている長手左右ミシン目２２ａ−１，２２ａ−２，２２ｂ−１，２２ｂ−２と、横手ミシン目２１ａ，２１ｂのほゞ中点を結ぶ中央ミシン目２３とからなり、これらは互いに連続しており、長手左右ミシン目の、横手中心線２を介して対向している末端の間の区間は、切り裂き用ミシン目を施されることなく左右連続部２４−１，２４−２が形成されている。これらの切り裂き用ミシン目は一列に形成されていてもよく、或は２列以上に形成されていてもよく、２列以上のミシン目は互に平行であることが好ましいが、互に交差していてもよい。ミシン目が２列以上に形成されていると、抽出バッグを拡開、開口するとき、袋本体の切り裂き開口が容易になり、かつ確実になる。シート材料５は、その切り裂き用ミシン目の外側に形成された四辺形状接着線域（図３には図示されていない）において、支持部材に接着されており、また、シート材料５の横手ミシン目、長手左右ミシン目及び左右連続部により区画される部分の横手中心線２及び長手中心線６により区画される４個の区画部は（図３に示されていない）、それに重ね合わされる支持部材１の拡開部の４区画部に、それぞれ１個以上の接着域（図示されていない）において接着される。

【００２４】
前記支持部材正・背面部３８ａ，３８ｂの中央切り込み線１３の両末端点と、前記正・背面横手切り込み線１１ａ，１１ｂとの間には、この区間を切り裂き可能にするミシン目又は不連続切り込み線１３ａ，１３ｂが形成されていてもよく、或は、前記正・背面中央切り込み線１３の両末端は、前記正・背面横手切り込み線１１ａ，１１ｂのほゞ中点に連続していてもよい。

支持部材３３の連続頭部に設けられた四辺形状連続又は不連続接着線域４２は、支持部材拡開部の周囲を強化し、かつ袋本体の開口部を保持し、かつ、支持部材の脚部下端を開いて抽出容器開口部の上縁端に載置したとき、互に接着された支持部材と袋本体との頭部を安定した拡開姿勢に保持することができる。
また、支持部材の拡開部と袋本体の拡開部とを接着する４個以上の拡開部接着域１７ａ−１〜１７ｂ−２は支持部材拡開部と袋本体の拡開部とを同時にスムースに拡開することを可能にする。
さらに支持部材正・背面脚部に形成される脚部接着域４４ａ，４４ｂは、支持部材の脚部を開いて抽出容器開口部上端縁上に載置したとき、同時に袋本体正・背面部を離間させて、袋本体を開き、その後の抽出操作を容易にすることができる。

図５には本発明の支持具付抽出バッグ（１）の他の例が示されている。支持部材３３の拡開部４３において、中央切り込み線の代りに広幅の中央切り欠き部１３Ｂが設けられていて、この中央切り欠き部４８の両端は、横手切り込み線１１ａ，１１ｂのほゞ中央部分に連続している。この中央切り欠き部４８において、袋本体３２の一部が露出しており、袋本体正・背面部の切り裂き用中央ミシン目２３を見ることができる。中央切り欠き部の形状は例えば図２−（Ｂ）〜（Ｅ）に示されたものを含めて適宜に設定することができる。
図５に示された支持具は抽出バッグにおいて、その支持部材正・背面部の各々の脚部の中央係合突起部には、その中央に中央凹部４９ａ，４９ｂが形成されていて、その左右両側に、１対の中央部左右係合突起部５０ａ−１，５０ａ−２，５０ｂ−１，５０ｂ−２が形成され、この中央部左右係合突起部とその外側の左右係合突起部４６ａ−１，４６ａ−２，４６ｂ−１，４６ｂ−２との間に、左右係合凹部４７ａ−１，４７ａ−２，４７ｂ−１，４７ｂ−２が形成される。このような中央部左右係合突起部は、それを抽出容器開口部上縁端の内側に差し込れたとき、抽出容器の内壁面に沿って容易に屈曲してこれに密着し、支持部材の載置状態を安定化することができる。
また図５において、左右係合突起体４６ａ−１と４６ａ−２、４６ｂ−１と４６ｂ−２はそれぞれ、係合連結部４８ａ，４８ｂにより連結されておりそれによって支持部材の載置状態をさらに安定化することができる。

【００３１】
本発明の支持具付抽出バッグの製造方法には格別の制限はないが、好ましくは、本発明の支持具付抽出バッグ製造用シート複合体（１）から製造することができる。製造用シート複合体（１）の１例が、図６に示されている。図６において、複合体５１は、透水濾過性シート部材５２と、このシート部材上に、互いに平行に配置された複数個の支持部材５３とを有し、
これらの支持部材５３は、その横手中心線５４と、前記シート部材の長手中心線５５とが、合致するように前記シート材料上に配置されており、かつ、
前記支持部材の各々は、その横手中心線５４の両側において対称形をなす２半部５３ａ，５３ｂからなり、この２半部は前記横手中心線５４において互に連続している。
【００３２】

【００３４】
（４）前記長手左右切り込み線１２ａ−１，１２ｂ−１及び１２ａ−２，１２ｂ−２の前記横手中心線を介して互に対向する両末端点は、互に離間していて、その中間区間に連続部１４−１，１４−２が形成されている。
また前記長手方向中央切り込み線は連続線であってもよく、或は不連続線であってもよい。前記中央連続切り込み線は、その両末端点と、それに対向する前記横手切り込み線のほゞ中央部との間において、この区間を切り裂き可能にするミシン目又は不連続切り込み線１３ａ，１３ｂにつながっていてもよく、或は、前記中央切り込み線１３又は中央切り欠き部の両末端は、それに対応する前記横手切り込み線１１ａ，１１ｂのほゞ中央部分に直接連続していてもよい。
【００３５】
（５）前記シート材料５２の、支持部材５３と接着している四辺形状連続又は不連続接着線域（図示されていない）の内側の、前記支持部材の拡開部の、前記支持部材横手切り込み線、長手左右切り込み線及び前記横手切り込み線に連続する長手方向中央連続又は不連続切り込み線又は中央切り欠き部（ミシン目又は不連続切り込み線部を含む）に重なり合う各部分に、図３に例示されているように、前記シート材料を切り裂き可能にする１個以上の切り裂き用ミシン目又は不連続切り込み線が形成されている。ミシン目又は不連続切り込み線が２列以上に形成されているときは、これらは互に平行であってもよく、或は交差していてもよい。
【００３６】
（６）前記支持部材の拡開部５９の、前記横手中心線５４と長手中心線６０により４分される各区画部分と、それに重なる前記シート材料部分とが少なくとも１個の、接着域１７ａ−１，１７ａ−２，１７ｂ−１，１７ｂ−２によって接着されており、

【００３７】
上記の構成を有するシート複合体は、その長手中心線５５に沿って支持部材５３を外側にして半折すると、その両面は、長手中心線５５に関して対称をなす形状となる。
【００３８】
本発明のシート複合体（１）から、本発明の支持具付抽出バッグ（１）を製造する工程の１例を図７を参照して説明する。
図７においてシート複合体５１を、その長手中心線５５に沿って半折し、かつその重ね合わされた側縁部を、接着機６１により接合しながら、製袋機（図示されていない）に供給する。半折されたシート複合体５１の１個の支持部材５３を含む部分５１Ａが製袋機の製袋、被抽出材料充填作業位置に来たとき、このシート複合体部分５１Ａと、その下流に隣り合うシート複合体部分５１Ｂの間の部分（間隔部）において、重ね合わされたシート部材間隔部をベルト状に接着し、このベルト状接着部を切断する。このとき、図７に示されているような接着切断機６２を用いてベルト状接着部のシート部材端縁に近い部分を直線状に接着し、これを接着部中央部において切断する。接着部の形状はＹ字状であってもよく、このときは接着部をＹ字状に切断し、その分岐する２辺の間の三角形部分を、切断クズとして、除去（例えば吸引除去）してもよい。この接着切断機６２は、シート部材が溶融接着可能な合成繊維を含有している場合、図７に示されているような、超音波ホーン（加熱部材）６４と、それに対向し、直線状接着・切断面を有するアンビル６５とを有するものであってもよい。
【００３９】
上記シート部材５２の互いに重ね合わされた側端縁部を接着する接着機６１として、図７に示されているような超音波シール機を用いることができる。また、シート部材間隔部の接着・切断操作により、当該シート複合体部分５１Ａの下流に隣り合う部分５１Ｂの上端部も同時に接着、封止され、完成された支持具付抽出バッグ５１Ｂとしてシート複合体部分５１Ａから分離する。
【００４０】
上述のようにして、シート材料の下端縁及び側端縁を接着されたシート複合体部分５１Ａに対し、その内側に、被抽出材料が充填される。このようにして被抽出材料を収容し、上端が開口している袋状の部分５１Ａは、その接着充填位置から、下流の位置に移動し、上記と同様にして、その上端開口部が接合封止され、その上流に隣るシート複合体材料から切断分離される。このようにして、支持具付抽出バッグ６６が得られる。
【００４１】
本発明の支持具付抽出バッグ（１）を用いて、抽出を行う場合の操作及び状況について、図８を参照して説明する。
図８において、抽出容器（カップ）６７の上端縁部６８上に、支持具付抽出カップ（１）６９が載置されている。この載置に当り、支持具付抽出バッグ（１）６９の支持体３３の１対の正・背面脚部４５ａ，４５ｂを開き、この脚部の中央係合突起部４１ａ（４１ｂ）を容器６７の内側に差し入れ、脚部の左右端部が容器上端縁上に位置するように載置する。脚部に左右係合突起部４６ａ，４６ｂ及び左右係合凹部４７ａ，４７ｂが形成されているときは、脚部の中央係合突起部４１ａ，４１ｂを、容器（カップ）６７の上端縁への内側に差し入れ、左右両係合突起部４６ａ，４６ｂを容器の外側に位置するようにして、係合凹部４７ａ，４７ｂに容器上端縁部６８が差し込まれるようにすれば、支持部材は、抽出容器上端縁部に係合して安定に保持される。また、図４に示されているように中央係合突起体にはその中央部に中央凹部が形成されている場合は、その外側の中央部左右係合突起部を抽出容器の内側に差し入れ、またその外側の左右係合突起部が係合連結部により連結されている場合は、これを抽出容器の外側に位置させて、中央係合突起部との間に抽出容器開口部上縁端を挟むようにする。
【００４２】
次に載置された抽出バッグの支持部材３３の拡開部４３の長手方向中央切り込み線（又は切り欠き部）１３の両側を下向きに押し込む。すると拡開部４３は中央切り込み線１３、横手切り込み線、長手切り込み線（図４，５参照）に沿って２分割され、この２分割片７０ａ，７０ｂはそれぞれ左右連続部１４−１，１４−２を拡開軸として、下向きに押し込まれ、支持部材の拡開部は開口する。このとき、同時に袋本体３２の拡開部も、その切り裂き用ミシン目又は不連続切り込み線（図３参照）に沿って切り裂かれ、押し込まれた支持部材拡開部の２分割片７０ａ，７０ｂにより開口される。すなわち、本発明の支持具付抽出バッグにおいては、支持部材及び袋本体の開口及び開口状態の維持（セット）が、単一操作により同時に達成することができる。
【００４３】
上記拡開操作により袋本体開口部の内側に押し込まれた拡開部の２分割片７０ａ，７０ｂは、支持部材及び袋本体の開口部の開口状態を安定に固定維持（セット）することができる。また、袋本体は、四辺形状連続又は不連続接着線域、拡開部接着域、及び必要により脚部接着域により支持部材に接着されているから、袋本体は開口状態のまゝ、それに収容されている被抽出材料とともに、開口載置されている支持部材から、抽出容器内に懸垂保持される。
このように容器上に載置された支持具付抽出バッグの開口部から、所定の抽出液、例えば熱湯を注下することにより、袋本体内の被抽出材料７１に抽出を施せば、形成された抽出液は、袋本体により濾過されて、容器内に流下する。
【００４４】
本発明の支持具付抽出バッグ（２）は、前述の支持具付抽出バッグ（１）と同様の構成を有するが、その四辺形状接着線域の内側の支持部材拡開部に形成される切り込み線又は切り欠き部の構成及び袋本体の四辺形状接着線域の内側の切り裂き用ミシン目又は不連続切り込み線の構成において、下記のように異るものである。
【００４５】

【００４６】
支持部材拡開部１０の長手切り込み線１２−３，１２−４のほゞ中央部の間には、長手中心線６と交差する横手方向中央切り込み線１３−１（連続線であってもよく、或は不連続線であってもよい）が形成されている。この中央切り込み線１３−１の両末端は、長手切り込み線１２−３，１２−４のほぼ中央部に直接連続している連続切り込み線であってもよく、又は不連続切り込み線であってもよく、或は図１に示されているように、切断容易なミシン目又は不連続切り込み線１３ａ−１，１３ａ−２が形成されていてもよい。
【００４７】
図９において、横手切り込み線１１−３，１１−４及び１１−５，１１−６のそれぞれの、互に対向する末端点の中間の区間は、切断されることなく連続していて左右連続部１４−３，１４−４が形成されている。
【００４８】
図９において、支持体拡開部１０の、長手中心線６と、横手中心線２により分画される４個の分画部は、それぞれ１個以上の拡開部接着域１８ａ−１，１８ａ−２，１８ｂ−１，１８ｂ−２により袋本体の展開シート材料５に接着されている。
【００４９】
支持部材の拡開部に形成される横手方向切り込み線の形状及び切り裂き用ミシン目、不連続切り込み線の有無は、図９の態様の他に、例えば、図１０−（Ａ）に示されているように、横手方向中央切り込み線１３−１が、長手切り込み線１２−３，１２−４に直接連続し、切り裂き用ミシン目又は不連続切り込み線がなくてもよく、及び／又は横手左右切り込み線１１−３〜１１−６のそれぞれが、図２−（Ａ）に示されているように長手切り込み線１２−３，１２−４にほゞ直角をなして連続していてもよく、両者の接続部は、図１０−（Ａ）に示されているように丸められていてもよく、或は丸められていなくてもよい。また、連続部１４−３，１４−４には、図９及び図１０−（Ａ）に示されているように、折り曲げ用ミシン目が形成されていてもよく、又は折り曲げ用押圧線が形成されていてもよく、或は連続部１４−３，１４−４における折り曲げが可能であれば、折り曲げ用ミシン目及び押圧線が形成されていなくてもよい。

図１０−（Ｂ）に示されている支持部材拡開部１０において、長手切り込み線１２−３，１２−４のほゞ中央部分を結ぶように横手方向中央切り欠き部１３−２が形成されている。この中央切り欠き部１３−２は支持部材と袋本体とからなる支持具付き抽出バッグ（２）が形成され、袋本体内に被抽出材料が収容封止された後、この中央切り欠き部から、その内側の袋本体（被抽出材料収容）の状態を観察することができる。
図１０−（Ｃ）に示されている支持部材拡開部１０においては、横手方向中央切り欠き部１３−３が、図１０−（Ｂ）の中央切り欠き部１３−２よりも広い幅をもって形成されており、図１０−（Ｄ）に示されている支持部拡開部１０において、中央切り欠き部１３−４は中央部において狭く、長手切り込み線１２−３，１２−４に近づくにつれて広くなる形状、例えばＸ字状輪郭を有しており、図１０−（Ｅ）に示されている支持部拡開部１０において、中央切り欠き部１３−５は、中央部において広く、長手切り込み線１２−３，１２−４に連続する部分において狭い形状例えば壺状輪郭を有している。本発明の抽出バッグ（２）において、支持部材拡開部１０の横手方向中央切り欠き部は、支持部材拡開部の作用効果を達成し得る限り、上記図１０−（Ｂ）〜（Ｅ）に示した例に拘らず、他の適宜の形状に形成することができる。
【００５１】
図１１には、図９に示された拡開部を有する支持部材１と重ね合わされた袋本体を展開したとき、シート材料５に形成される引き裂き用ミシン目又は不連続切り込み線（以下切り裂き用ミシン目と記す）の一例が示されている。この切り裂き用ミシン目は、図１１に示されているように、長手中心線６に平行な、互に離間した長手ミシン目２２−３，２２−４と、その上下両端から長手中心線６に向って伸びている横手ミシン目２１−３，２１−４，２１−５，２１−６と、長手ミシン目２２−３，２２−４のほゞ中央部分を結ぶ３本の横手方向中央ミシン目２３−１とからなり、これらは互いに連続しており、横手上下ミシン目の、長手中心線６を介して対向している末端の間の区間は、切り裂き用ミシン目を施されることなく上下連続部２４−３，２４−４が形成されている。シート材料５は、その切り裂き用ミシン目の外側に形成された四辺形状接着線域（図１１には図示されていない）において、支持部材に接着されており、また、シート材料５の長手左右ミシン目、横手ミシン目及び上下連続部により区画される部分の長手中心線６及び横手中心線２により区画される４個の区画部は（図１１に示されていない）、それに重ね合わされる支持部材１の拡開部の４区画部に、それぞれ１個以上の接着域（図示されていない）において接着される。上記切り裂き用ミシン目は１列に形成されていてもよく、或は２列以上に形成されていてもよい。ミシン目が２列以上に形成されている場合、これらは互に平行であってもよく、互に交差していてもよい。２列以上のミシン目は、抽出バッグが拡開、開口するとき、袋本体の切り裂き開口を容易かつ確実にすることができる。
【００５２】
本発明の支持具付抽出バッグ（２）の製造方法には格別の制限はないが、好ましくは、本発明の支持具付抽出バッグ製造用シート複合体（２）から製造することができる。製造用シート複合体（２）は、シート複合体（１）と同様の構成を有するが、但し、支持部材の拡開部は、例えば図９に示されているように、支持部材の四辺形状連続又は不連続接着線域の内側に、拡開部が形成されていて、この支持部材拡開部が、横手支持部材中心線にほゞ直角をなす方向に、それと交差し、かつ互に離間して伸びる２本の長手方向切り込み線と、この長手方向切り込み線の上下両端から、前記横手中心線にほゞ平行に、かつ互に対向して伸びる４本の横手切り込み線と、前記長手方向切り込み線のほゞ中央部の間に、前記横手中心線にほゞ平行に、伸びる横方向中央連続又は不連続切り込み線又は中央切り欠き部とを有している。
