Description

【０００１】
【発明の属する技術分野】
本発明は、引出係合片を有する物品支持体、前記支持体を有する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、物品を容器内に保持するための引出係合片を有する物品支持体、この支持体を用いて抽出バッグを、抽出容器上に安定して載置し、安全に抽出を行うことができる支持体付抽出バッグ、及びこの支持体付抽出バッグを、容易にかつ効率よく製造することができる支持体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（特許文献１）及び特開平８−３３５７２号（特許文献２）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。
また、特開平１１−２８５４４３号（特許文献３）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。さらに、特開平１０−２１６０１７号公報（特許文献４）に開示されている濾過具は、カップなどの容器上面に載置可能な濾過具本体と、その内側に取り付けられた袋体とからなり、濾過具本体は容器上部を、外側から挾持できる一対の挾持部と、挾持部の上側に、容器の開口部上縁と当接する載置部とを有するものである。
【０００３】
さらに、特開平６−１１３９５２号公報（特許文献５）には、不織布からなるほぼ三角形状の袋状フィルターの正・背両面の上半部に保持片を接着し、各保持片から、２個の把手を引き出し、各把手に１個の切れ込み凹部を設けたフィルターが開示されている。
しかしながらまた、特開平１１−１７８７２０号公報に開示されているドリップバッグは、透水性濾過性シート材料からなる袋本体と、薄板状材料からなり袋本体の対向する２面上に設けられた、掛止部材とからなるものであり、掛止部材は、周縁部と、その内側に形成され、引出し可能なアーム部と、このアーム部の内側に形成された舌片部とからなり、アーム部はその上下端のいずれかで、周縁部に連続し、他端で舌片部と連続しているものである。
上記従来のフィルター又はドリップバッグは、その係合片（把手）の使用長さが一定であるため、それと係合すべき容器開口部の形状・寸法によっては、安定な保持が困難になることがある。このため、係合片の引出方向、角度などを適宜に設定することにより、係合片を、種々の寸法・形状の容器開口部に、容易に係合することが可能な支持体が強く要望されていた。従来の支持体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。

前記袋本体の正・背両面部のそれぞれの上半部に、前記支持体が、その上端縁とそれに平行に形成された上端縁部切込線との間の上端縁部の中央部分及び前記中央垂下部の一部分において、接着されていることを特徴とし、
それによって、前記袋本体の上端縁を開口し、この開口した袋本体を、抽出容器の内部に位置させ、前記支持体の中央垂下部を、抽出容器内に位置させたとき、前記円弧帯状張出部を、前記抽出容器の外側に位置させ、前記係合用空隙部内に、前記抽出容器の上端縁を位置させることにより、前記１対の支持部材によって、前記開口した袋本体を前記抽出容器内に保持することができるものである。
本発明の支持体付き抽出バッグ製造用シート複合体（２）は、透水濾過性シート材料と、その上に接着された本発明の係合用空隙部を有する物品支持体（２）からなる複数個の支持体とを有し、
前記支持体は、前記シート材料の長手中心線の両側に、前記長手中心線から離間し、かつ前記長手中心線に関し互に対称をなす位置に、前記支持体の前記上端縁が、前記シート部材の側縁に対向し、前記支持体の円弧帯状張出部が前記シート材料の長手中心線に対向するように配置され、前記支持体が、その上端縁の中央部分及び前記中央下垂体の一部に設けられた接着域において、前記シート材料に接着されていることを特徴とするものである。
【０００７】
【発明の実施の形態】
本発明の係合空隙部を有する物品支持体（１）は、保形・耐水性シート材料からなるものであって、この支持体は、その上端縁部及び下端縁部に、それぞれ、上端縁及び下端縁にほぼ平行に形成された切込線と、前記下端縁部切込線の左右両端から、上向に向って伸びる左右１対の上向き切込線と、これら左右１対の上向き切込線の上端から、上方内側に向って拡大するように形成された、左右１対の係合用空隙部とを有するものである。
【０００８】
図１に示された本発明の物品支持体（１）の一態様において支持体（１）１は、横長四辺形の形状を有し、その上端縁部分２及び下端縁部分３には、それぞれ上端縁２ａ及び下端縁３ａにほぼ平行に伸びる上端縁部切込線４及び下端縁部切込線５が形成されている。前記上・下端縁部切込線４，５は、図１に示されているような直線形であってもよいし、或は、下向きに凸の円弧形線又は波形線であってもよい。
図１において、下端縁切込線５の左右両端から、上方に向って伸びる左右１対の上向き切込線６ａ，６ｂが形成されていて、この左右１対の上向き切込線６ａ，６ｂの上端から上向き内側に向って拡大する左右１対の係合用空隙部７ａ，７ｂが形成されている。
【０００９】
図１において、下端縁部切込線５と、左右１対の上向き切込線６ａ．６ｂの連結部は、丸められていてもよい。また、係合用空隙部７ａ，７ｂの形状には、それが、上向き切込線の上端から上方内側に向って拡大している限り、格別の制限はないが、図１に示されているように拡大した頭部の下側に、下向きに伸び出す凹部８ａ，８ｂと、それに隣る凸部９ａ，９ｂとが形成されていることが好ましい。この係合空隙部７ａ，７ｂ頭部の凹部８ａ，８ｂ及び凸部９ａ，９ｂは、支持体と物品との係合を安定させるために有効である。
【００１０】
図１において、上端縁部切込線４及び下端縁部切込線５は、支持体の両切込線の中間の係合部１０を、上下端縁部２，３から独立に変形することを可能にし、かつ係合部１０が左右係合空隙部において、物品に係合したとき、下端縁部３を、係合した係合部から独立して変形することを可能にし、かつ下端縁部３を、物品に係合した係合部１０と協働する係合手段として利用することを可能にする。
【００１１】
支持体を形成するシート材料は、保形・耐水性シート材料から選ばれる、シート材料の保形性とは、シート材料に湾曲、屈折などの変形が施されたとき、シート材料が、その変形された形状を保持し、弾性的に復元することがない特性を意味する。耐水性とは、水、特に熱水に接触したとき、透水、軟化、変形、変質、破断などを、生じない特性を意味する。このようなシート材料としては、例えば厚さ３０〜４０μｍの、防水塗工系、プラスチックシート又は気孔質合成樹脂シート（合成紙など）などを用いることができる。
【００１２】
図２には本発明の係合体付き抽出バッグの一実施態様（１）が示されている。図１において、支持体付抽出バッグ（１）１１は、袋本体１２と、２個の本発明の支持体１とから構成される。袋本体１２は、透水・濾過性のシート材料により形成される。このような透水・濾過性シート材料としては、濾紙、濾布及び濾過用不織紙を用いることができる。濾過用不織布は、例えばポリオレフィン系極微細繊維（例えば、ポリエチレン及びポリプロピレン極微細繊維）、ポリエステル系極微細繊維、並びに前記合成重合体極微細繊維と、通常の濾過用親水性繊維（例えば、レーヨン繊維など）との混合繊維から製造されたものを包含する。
袋本体１２は、前記透水・濾過性シートを、その中心線に沿って半折して形成された正・背両面部１３，１４を有している。この正・背両面部は、前記半折により形成された端縁、例えば、下端縁１５ａにおいて、互に連続しており、その他の端縁１５ｂ，１５ｃ，１５ｄにおいて、それぞれ接合封止されている。上端縁１５ｄは、剥離可能に接着封止されていてもよいし、或は、剥離開口不能に十分に接着され、その下に近接して引裂き用ミシン目（図示されていない）が形成されていてもよい。
【００１３】
本発明の抽出バッグ（１）の袋本体には、被抽出材料が収容されている。被抽出材料には、それが水、熱湯などにより抽出可能である限り、格別の限定はないが、コーヒー粉末、緑茶、紅茶、各種中国茶、ハーブ茶、及び各種被抽出用健康剤などを用いることができる。
【００１４】
２個の支持体１のそれぞれは、その上端縁部２に設けられた少なくとも１個の接着域１６において、袋本体１２の正・背両面部のそれぞれの上半部に接着されている。袋本体１２と支持体１との接着において、袋本体及び支持体の少なくとも一方を他方と融着することが好ましいが、接着剤を用いてもよい。接着剤の種類には格別の制限はないが、一般的無毒性・耐水性接着剤を用いることが好ましい。図２に示された抽出バッグにおいては、各支持体は、その下端縁部３に設けられた接着域１７においても、袋本体１２の正・背いずれかの面部１３又は１４に接着されている。
【００１５】
図２の抽出バッグ（１）を、その支持体（１）により、抽出容器に係合するには、袋本体の上端縁を開口し、又は開口せずに、図３に示されているように、抽出バッグ１１を抽出容器２１の開口上端縁部上に配置し、袋本体１２の下半部分を容器２１の開口部内に入れながら、袋本体１２を支持する支持体１の、下端縁部３を抽出容器２１の内側に位置させ、かつ係合部１０を抽出容器２１の外側に位置させ、その係合用空隙部７ａ，７ｂ中に、抽出容器２１の上端縁を位置させ、それによって、被抽出材料を収容している袋本体を、１対の支持体１を介して、抽出容器の開口部内に安定して保持する。
袋本体１２の上端縁は、支持体と、抽出容器の係合前に開口してもよく、或は係合後に開口してもよい。開口された袋本体は、保形・耐水性シート材料からなる支持体の保形基体部によりその開口状態を安定して保持することができる。
【００１６】
図４は、本発明の支持体（１）付き抽出バッグ製造用シート複合体（１）の一例の平面説明図である。
図４において、抽出バッグ製造用シート複合体３１は、透水濾過性シート材料３２と、その上に接着された本発明の引出係合片付き物品支持体からなる複数個の支持体３３ａ，３３ｂ，３４ａ，３４ｂ…３６ａ，３６ｂ…を有し、シート材料３２の長手中心線３７の左右両側に支持体３３ａと３３ｂ、３４ａと３４ｂ、３５ａと３５ｂ、３６ａと３６ｂ…が、互に１対をなして、長手中心線から離間して配置されていて、１対をなす支持体、３３ａと３３ｂ、…３６ａと３６ｂ…は、長手中心線に対し、対称をなす位置に、各支持体の上端縁部２がシート材料３２の左右側縁３８，３９に対向し、各支持体の下端縁部３が、シート材料３２の長手中心線３７に対向するように配置されている。各支持体３３ａ…３６ｂ…は、その少なくとも上端縁部１６に設けられた接着域１６においてシート材料３２に接着されている。図４においては、各支持体は、その上端縁部２における接着域１６に加えて下端縁部３における接着域１７においても接着されている。
【００１７】
図４において、支持体中の引出係止片の形状を示す切込線及び接着域が支持体３３ａ，３３ｂにのみ記載されていて、その他の支持体においては、その記載が省略されているが、他の支持体３４ａ…３６ｂ…にも、支持体３３ａ，３３ｂと同様の切込線及び接着域が形成されている。図４において、互に隣接する支持体３３ａと３４ａ、３４ａと３５ａ…及び３３ｂと３４ｂ、３４ｂと３５ｂの対向する側端縁の間隔は均一であり、点線４０は、隣接支持体の対向する側端縁の間隔部の中心線を示し、これは、このシート複合体から抽出バッグが形成されるときの切断予定線を示すものである。
【００１８】
本発明の抽出シートは、前記シート複合体から製造することができる。
図５においてシート複合体３１を、その長手中心線３７に沿って、支持体が外側に位置するように半折し、その重ね合わされた側端縁部３８，３９を、側端縁接着機４１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３１の１対の支持部材３４ａ，３４ｂを有する部分４２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６２と、その下流に隣り合うシート複合体部分４３との間の部分（間隔部）において、重ね合わされた間隔切断部４４を帯状に接着し、この帯状接着部６４その中心線に沿って切断する。このとき、例えば図５に示す接着切断機４５を使用する。すなわち、シート複合体の、隣接する支持体の間の間隔切断部４４を、その中心線に沿って帯状に接着し、形成された帯状接着部をその中心線において切断する。接着部の形状は、Ｙ字状であってもよく、このとき発生する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４５は、シート材料が、溶融接着可能な合成繊維を含有している場合、図５に示されているような超音波ホーン（加熱部材）４６と、それに対向し、所望の形状の接着・切断面を有するアンビル４７とを有するものであってもよい。
【００１９】
図５に示されているように、シート材料３１の互に重ね合わされた側端縁部３８，３９を接着する接着機４１は超音波シール機であってもよい。
またシート材料間隔部４４の接着・切断操作により、当該シート複合体部分４２の下流に隣り合う部分４３の上端部も同時に接着、封止され、完成された支持体付抽出バッグ４３としてシート複合体部分４２から分離する。
上述のようにして、シート材料３２の下端縁及び側端縁が接着されたシート複合体部分６２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４２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、その上流に隣接す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、支持体付抽出バッグ４８が得られる。
【００２０】
本発明の係合空隙部を有する物品支持体（２）は、保形・耐水性シート材料から形成されたものであって、基体部と、この基体部の左右両下端部から、下方にほぼ円弧状をなして伸び出ている円弧状張出部と、前記基体部の下端中央部から、前記円弧帯状張出部に向って伸び出し、かつその下端が前記円弧状張出部の内側線から離間している中央垂下部と、前記基体部の下端、中央垂下部、及び前記円弧状張出部の内側線により規定される係合用空隙部とを有することを特徴とするものである。
【００２１】
図６は本発明の物品支持体（２）の一態様を示すものであって、この支持体５１は、保形・耐水性シート材料から形成されており、基体部５２、円弧帯状張出部５３と、中央垂下部５４と、上記基体部５２の下端５２ａ、中央垂下部５４及び円弧状張出部５３の内側線５３ａにより規定される係合用空隙部５５とを有している。円弧帯状張出部５３は基体部５２の左右両下端部から、下方にほぼ円弧状をなして伸び出ている。また中央垂下部５４は、基体部５２の下端５２ａの中央部から、円弧帯状張出部５３に向って伸び出し、但し、その下端５４ａは円弧帯状張出部５３に連続することなく、円弧帯状張出部の内側線５３ａから離間している。基体部５２、中央下垂部５４、円弧帯状張出部５３の間には、支持体が物品に係合するに十分な係合用空隙部５５が形成されている。
図６の支持体５１においては、基体部５２の上端縁部５２ｂに切込線５６が形成されている。この切込線５６を設けることによって、支持体５１が、その上端縁部５２ｂ内の接着域（図示されていない）において、物品例えば抽出バッグ用袋本体（図示されていない）に、接合され支持体上端縁部５２ｂが袋本体の変形に対応して変形した場合でも、支持体の切込線５６より下の部分は、上端縁部５２ｂの変形に拘らず、その円弧帯状張出部５３、中央下垂部５４及び係合用空隙部５５を、物品係合に好適な形状に変形することが容易になる。
支持体（２）を形成するシート材料は前記支持体（１）から用いられる保形・耐熱性シート材料から選ぶことができる。
【００２２】
図７には、図６の物品支持体を抽出バッグ用支持体として用いたときの支持体付抽出バック（２）の一態様が示されている。
図７において、支持体付抽出バッグ（２）６１は袋本体１２、２個の本発明の支持体１とから構成される。袋本体１２を形成する透水濾過性シート材料は、前記抽出バッグ（１）と同一の材料から選ぶことができる。
袋本体１２は透水濾過性シート材料を、その中心線に沿って半折して形成された正・背両面部１３，１４を有し、この正・背両面部１３，１４は前記半折により形成された端縁例えば下端縁１５ａにおいて、互に連続しており、その他の端縁１５ｂ，１５ｃ，１５ｄにおいて、それぞれ接合封止されている。上端縁１５ｄは、剥離可能に接着封止されていてもよく、式は剥離開口不能に十分に接着され、その下に近接して引裂き用ミシン目（図示されていない）が形成されていてもよい。
抽出バッグ（２）の袋本体１２中には、前記抽出バッグ（１）と同様の被抽出材料が収容封止されている。
【００２３】
図７の抽出バッグにおいて、袋本体１２の正・背両面部１３，１４上の支持体６１の各々はその基体部５２の上端縁部５２ｂに設けられた１個以上の接着域６２において、袋本体１２の正・背両面部１３，１４の各々に接着されている。また支持体は、中央下垂部５４に設けられた少なくとも１個の接着域６３において、袋本体の正・背両面部１３，１４の各々に接着されている。接着域６２に加えて、接着域６３においても袋本体の正・背両面部の各々に接着されていることによって、支持体５１の中央下垂部５４は、常に袋支持体に接合しているから、抽出バッグを、抽出容器に係合するとき、円弧帯状張出部のみを手指により操作すればよく、また、支持体の中央垂部５４は基体部５２とともに袋本体を開口した状態に安定に保持することができるという利点を発現する。
【００２４】
図７の抽出バッグ（２）をその支持体（２）により抽出容器に係合するには、袋本体の上端縁を開口し、図８に示されているように抽出バッグ６１を抽出容器も７１の開口部上端縁部上に配置し、袋本体１２の下半部分を容器７１の開口部内に入れながら、袋本体１２を支持している２個の支持体５１の各々の中央下垂部５４を容器内例に位置させ、円弧帯状張出部５３を容器の外側に配置し、容器開口上端縁部を、支持体の係合用空隙部５５中に係合させる。このようにすると容器開口部に配置された２個の支持体５１により支持されている袋本体１２は、係合用空隙部５５内に係合した容器開口部の上端縁上に、１対の円弧帯状張出部５３により、安定に保持される。袋本体の上端縁は、支持体と、抽出容器とを係合させた後に開口してもよい。開口した袋本体は、保形耐水性シートからなる支持体により、その開口状態に安定に保持される。
【００２５】
図９は、本発明の支持体（２）付き抽出バッグ製造用シート複合体（２）の一例の平面説明図である。
図９において、抽出バッグ（２）製造用シート複合体（２）８１は、透水濾過性シート材料３２と、その上に接着された本発明の引出係合片付き物品支持体からなる複数個の支持体８２ａ，８２ｂ，８３ａ，８３ｂ…８５ａ，８５ｂ…を有し、シート材料３２の長手中心線３７の左右両側に支持体８２ａと８２ｂ、８３ａと８３ｂ、８４ａと８４ｂ、８５ａと８５ｂ…が、互に１対をなして、長手中心線から離間して配置されていて、１対をなす支持体、８２ａと８２ｂ…８５ａと８５ｂ…は、長手中心線に対し、対称をなす位置に、各支持体の上端縁部５２ｂがシート材料３２の左右側縁３８，３９に対向し、各支持体の円弧帯状張出部５３が、シート材料３２の長手中心線３７に対向するように配置されている。各支持体８２ａ…８５ｂ…は、その少なくとも上端縁部５２ｂに設けられた接着域６２においてシート材料３２に接着されている。図７においては、各支持体は、その上端縁部６２の接着域６２及び中央下垂部５４の接着域６３において接着されている。
【００２６】
図９において、支持体中形状、構造が支持体８２ａ，８２ｂにのみ記載されていて、その他の支持体においては、その記載が省略されているが、他の支持体８３ａ…８５ｂ…も、支持体８２ａ，８２ｂと同様の形状、構造を有している。図９において、互に隣接する支持体８２ａと８３ａ、８３ａと８４ａ…及び８２ｂと８３ｂ、８３ｂと８４ｂの対向する側端縁の間隔は均一であり、点線６０ａは、隣接支持体の対向する側端縁の間隔部の中心線を示し、これは、このシート複合体から抽出バッグが形成されるときの切断予定線を示すものである。
【００２７】
本発明の抽出シート（２）は、前記シート複合体（２）から製造することができる。その製造は図５に示された方法と同様にして行われる。
【００２８】
本発明の物品支持体（１）において、その上端縁部の切込線及び下端縁部切込線は図に示されているように、直線状であってもよいが図１０に示されている物品支持体（１）９１のように、その上端縁部２の切込線９２及び下端縁切込線９３のように下向きに凸の曲線状であってもよく、左右上向き切込線９４，９５は、下端縁切込線９３にスムースに連続する上向き曲線をなしていてもよい。
同様に、本発明の物品支持体（２）においても図６に示されている直線状切込線５６は、下向きに凸の曲線をなしていてもよい。
