【技術分野】
【０００１】
本発明は、紙パック容器に収容されたジュース、清涼飲料水、特に、ゼリー食品等の内容物を、吸引力を使用しないで外部からの押圧で飲用できるストローを具えた押圧変形可能な紙パック容器に関する。
【背景技術】
【０００２】
図１６に示すように、牛乳、清涼飲料、ジュースなどの各種飲料を収容した紙パック容器１は、内部の各種飲料を飲用するためにストロー３を刺し込む挿入部２を容器の上面部９に設け、該挿入部を覆っている密封膜に先端を刺し込んだストローの上端から飲料を飲用している。ストロー３は、挿入部２に刺し込みやすくするため先端を斜状にし、透明袋５内に収容した状態で容器１の外面に取付けたものが特開２０００−３１３４３５号に示されている。
【特許文献１】
特開２０００−３１３４３５号公報
【０００３】
従来のストロー３は、紙パック容器１の高さより長く形成し、該容器の外側に斜めに取付け、挿入部２に挿入した先端は容器の底部に届く長さを有し、内容物の液面が下がってもストローの先端は底部に届いているので該容器を傾けて片寄せた内容物を残さずに飲むことができる。しかし、挿入部２に刺し込んだストローを口に咥えて吸引しながら飲んだり、他の哺乳瓶やコップに移し替える場合、内容物が外部に流出すると容器内は徐々に減圧してストローから内容物が出なくなるため、該容器を外側から押圧して内圧を高める必要がある。
【０００４】
飲用によって内容物が減った容器を逆さにすると、ストローの先端が飲料から露出して内容物が飲めなくなる。また、ストロー３は、断面が同一形状で挿入部２に単に刺し込んであるため、誤って外方に引張ると挿入部２から簡単に抜けて、内容物が容器から流出して洋服などを汚すおそれがあった。このように従来のストローの有する問題点に鑑みて改善したストローが、特開２００２−２４９１７２号や特開２００２−３５５１６１号に示されている。
【０００５】
図１に示す如く、紙などからなる押圧変形可能な容器２０に設けた挿入部３６に挿入する改良型のストロー４ａは、該容器内に一定以上挿入しないよう略中間部に任意形状の係止部６を設け、挿入部３６に掛止してある。係止部６から容器２０を形成する素材の厚みＷと略同じ間隔を隔てた位置に通孔７、また、ストロー先端に斜状の開口部８を夫々設けてある。通孔７は１個でも複数個でもよい。この容器内の飲料は、ストローの開口部８の他に、通孔７から流出させて飲むことができる。
【０００６】
挿入部３６に刺し込んだストロ−４ａから内容物をコップや哺乳瓶に移し替える場合、ストローの係止部６に接近して１又は２以上の通孔７を設けてあるため、容器２０内の飲料は、開口部８または通孔７から取込んで他の容器に移し替えることができる。この場合、従来の長いストローだと、容器内の飲料が減少するとストローの先端が飲料外に露出して内容物を飲めなくなるが、図１に示すストロー４ａは、先端に設けた開口部８の他に、容器２０の壁面に接近して通孔７を設けてあるので、容器を逆さにすれば内容物を最後まで飲んだり、移し替えることができる（図１４）。
【０００７】
上記改良ストロー４ａの原理を利用した図２〜４に示す他の改良型ストロ−４ｂの先端は、容器に設けた挿入部３６に刺し込みやすくするためテーパー状をした先細筒１１の先端に斜状の開口部８ａを設け、中間部分には一定範囲で伸縮可能で折曲可能な蛇腹部１０と挿入部３６に刺し込んだストロー４ｂが簡単に脱出しないように、外径を略テーパー状にしてストッパー機能を有する係止部６ａ及び段部６ｂを設け、該係止部に接近して通孔７ａを設けてある。図３に示すストローは、係止部６ａの最大外径部に連続して垂直な段部６ｂをストロー外周面に設けてあり、図４に示すストローは係止部６ａの最大外径部に連続した補強機能を有する筒状部６ｃの端部から垂直に設けた段部６ｂをストロー外周面のベース部１２に連続して設けてある。
【０００８】
容器２０の内容物が減少してストロー４ｂ先端の開口部８ａが飲料外に露出すると(図１４)、内容物は通孔７ａからストロー内に進入する。即ち、該容器２０の底面部を上方にして挿入部３６に刺し込んだストロ−４ｂを口にくわえて吸い込めば最後まで飲用することができる。また、コップや哺乳瓶に内容物を移し替える場合は、残量が減ってストローの開口部８ａが飲料外に露出しても通孔７ａから内容物を取り込めるので他の容器に移し替えることができる。
【０００９】
従来の紙パック容器１の代表的なものを図１６に示すが、内面にアルミ箔やポリエチレン樹脂などの耐水薄膜１３（図１４）を設けた厚紙材を筒状に形成し、その上下端縁を密着させて方形箱型に折り曲げ、両側面部の上下左右に夫々突出させた三角突部を下方に折り曲げ、側面部及び底面部に接着結合して全体を矩形箱型に組立ててある。
【発明の開示】
【発明が解決しようとする課題】
【００１０】
紙パック容器１の上面部９に設けた挿入部２を密封している耐水膜は、ストロー３を刺し込むと該ストローの外周面に密着して外部に対して密封し、該ストローを口に咥えて吸引すると内容物の減少に応じて容器１の内部に生じる負圧により、該容器は外方から押圧されて変形する。その後、ストロー３から口を離すと該負圧により外気を内部に取り込んで元の状態に復帰し、再びストローを口に咥えて吸引し、之を繰返しながら内容物を飲むものである。一般的に、容器内の内容物はストローを口に咥えて吸引力により飲用するのが普通である。
【００１１】
しかし、清涼飲料などのように水溶液でなく、ゼリー飲料のように粘度を有する粘性流体の内容物の場合は、ストローで飲用するには強い吸引力を必要とする。そのため、乳幼児や病人や老人など体力が弱いと強い吸込力を出せないので、内容物を飲用することが困難であった。
さらに、軟らかい樹脂部材、例えばポリエチレンやアルミ箔などの柔軟な部材で形成して絞り込み可能な容器を手で保持して絞り込みながら中身のゼリー飲料を押し出す容器もある。この場合、吸引力は必要ではないが、絞り込むという強い力を必要とする上、容器の材料コストがかかり、その上、飲み終わった後の容器は、分別を必要とするためごみ処理に手間がかかる等という問題点を有していた。
【００１２】
本発明は、押圧変形可能な紙パック容器の外側から押圧して折畳み、吸込力を必要とすることなく中身の内容物を最後まで飲用し、また、他の容器に移し替えることができる紙パック容器及びストローを提供することを目的とする。
【課題を解決するための手段】
【００１３】
本発明は、内面に耐水薄膜を設けた厚紙材を筒状に形成し、その上下端縁を密封し、これを折り曲げて、それぞれ対向する上面部３５及び底面部２４、前面部３０及び後面部３８、並びに1対の側面部２５，２５を形成すると共に、前記上面部３５に位置して左右に突出させた三角突部２１，２１を側面部２５，２５に密着し、前記底面部２４に位置して左右に突出させた三角突部２２，２２を底面部２４に密着して方形箱型に成形し、前記上面部３５にストロー挿入用の挿入部３６を設けた容器２０であって、ストロー挿入用の挿入部３６を有した前記容器２０の該挿入部に着脱可能に装着されるストロー４ｂは、円管状のベース部１２と、前記容器の内面に係止してストローの脱出を防止するため外径が飲み口側から通孔側に向かって漸減するテーパー部を有し、且つ、テーパー部の最大外径がベース部１２の外径とストロー管壁の厚さとの和より小さく、ベース部の外径より大きく設けた係止部６ａと、該係止部に隣接した少なくとも1個の通孔７ａとを有し、該通孔の開口面積の合計がベース部の直径方向断面積と同等以上の開口面積を有し、三角面部２７ａ，２７ａの両頂部２８，２８を通り、底面部２４に平行な第1水平折目３１を具え、前記第1水平折目３１から底面部２４の幅W１の自然数倍の距離を存し、かつ第1水平折目３１に平行な少なくとも1本の補助折目３２を具え、前記三角突部２１，２１の両頂部２３，２３を通り、上面部３５に平行な第2水平折目３４を具えると共に、前記三角突部２１，２１を側面部２５，２５に加熱加工により弱く接着結合させてなることを特徴とする。この三角突部は側面部に弱く接着してあるので、爪を痛めることなく該側面部から容易に剥すことができ、該容器の側面部の上方部分を容易に折畳んで内容物を押し出すことができる。
また本発明は、内面に耐水薄膜を設けた厚紙材を筒状に形成し、その上下端縁を密封し、これを折り曲げて、それぞれ対向する上面部３５及び底面部２４、前面部３０及び後面部３８、並びに1対の側面部２５，２５を形成すると共に、前記上面部３５に位置して左右に突出させた三角突部２１，２１を側面部２５，２５に密着し、前記底面部２４に位置して左右に突出させた三角突部２２，２２を底面部２４に密着して方形箱型に成形し、前記上面部３５にストロー挿入用の挿入部３６を設けた容器２０であって、ストロー挿入用の挿入部３６を有した前記容器２０の該挿入部に着脱可能に装着されるストロー４ｂは、円管状のベース部１２と、前記容器の内面に係止してストローの脱出を防止するため外径が飲み口側から通孔側に向かって漸減するテーパー部を有し、且つ、テーパー部の最大外径がベース部１２の外径とストロー管壁の厚さとの和より小さく、ベース部の外径より大きく設けた係止部６ａと、該係止部に隣接した少なくとも1個の通孔７ａとを有し、該通孔の開口面積の合計がベース部の直径方向断面積と同等以上の開口面積を有し、三角面部２７ａ，２７ａの両頂部２８，２８を通り、底面部２４に平行な第1水平折目３１を具え、前記第1水平折目３１から底面部２４の幅W１の自然数倍の距離を存し、かつ第1水平折目３１に平行な少なくとも1本の補助折目３２を具え、前記三角突部２１，２１の両頂部２３，２３を通り、上面部３５に平行な第2水平折目３４を具えると共に、前記上方三角突部２１，２１を側面部２５，２５にフイルム４０で密封包装させることを特徴とする。このフイルムを破ることにより三角面部を側面部から剥せるので、該容器の側面部の上方部分を折畳んで内容物を押し出すことができる。
さらに本発明は、内面に耐水薄膜を設けた厚紙材を筒状に形成し、その上下端縁を密封し、これを折り曲げて、それぞれ対向する上面部３５及び底面部２４、前面部３０及び後面部３８、並びに1対の側面部２５，２５を形成すると共に、前記上面部３５に位置して左右に突出させた三角突部２１，２１を側面部２５，２５に密着し、前記底面部２４に位置して左右に突出させた三角突部２２，２２を底面部２４に密着して方形箱型に成形し、前記上面部３５にストロー挿入用の挿入部３６を設けた容器２０であって、ストロー挿入用の挿入部３６を有した前記容器２０の該挿入部に着脱可能に装着されるストロー４ｂは、円管状のベース部１２と、前記容器の内面に係止してストローの脱出を防止するため外径が飲み口側から通孔側に向かって漸減するテーパー部を有し、且つ、テーパー部の最大外径がベース部１２の外径とストロー管壁の厚さとの和より小さく、ベース部の外径より大きく設けた係止部６ａと、該係止部に隣接した少なくとも1個の通孔７ａとを有し、該通孔の開口面積の合計がベース部の直径方向断面積と同等以上の開口面積を有し、前記三角面部２７ａ，２７ａの両頂部２８，２８を通り、底面部２４に平行な1水平折目３１を具え、前記第1水平折目３１から底面部２４の幅W１の自然数倍の距離を存し、かつ1水平折目３１に平行な少なくとも1本の補助折目３２を具え、前記三角突部２１，２１の両頂部２３，２３を通り上面部３５に平行な第2水平折目３４を具えると共に、前記一対の側面部２５，２５に、側面部２５，２５と底面部２４のなす交線である底辺部２６、２６を底辺とした二等辺三角形状の三角面部２７ａ，２７ａを画定する逆Ｖ型折目２７、２７と、三角面部２７ａ，２７ａの頂点２８、２８から三角突部２１、２１の頂部２３、２３に向かって延在する縦折目２９、２９を具えることを特徴とする。このように上下端縁を密封した方形箱型の対をなす側面部に設けた縦折目と、下方に設けた逆Ｖ型折目の頂部を連結して設けてあるので、側面部の下部に設けた三角面部を外方に突出させて該側面部を二つ折りに平坦状に折畳んで内容物外部に押し出すことができる。
また本発明は、前記三角面部２７ａ、２７ａの両頂部２８、２８を通り、底面部２４に平行な第１水平折目３１を具えることを特徴とする。そのため、この方形箱型の底面部の手前部分を第１水平折目から前面部上に平坦状に折畳むことができる。
また本発明は、前記第１水平折目３１が、前面部３０及び後面部３８の少なくとも一方を通ることを特徴とする。この第１水平折目３１は前面部３０に設けてもよいし、また後面部３８に設けても同様に作用する。
また本発明は、前記第１水平折目３１と底面部２４との間の距離ｄ１が、底面部２４の幅ｗ１の１／２であることを特徴とする。そのため、底面部２４の手前側部分が第1水平折目３２を内側にして前面部３０上に平坦状に折畳むことができる。
また本発明は、前記第１水平折目３１から底面部２４の幅ｗ１の自然数倍の距離を存し、かつ第１水平折目３１に平行な少なくとも１本の補助折目３２を具えることを特徴とする。このように大型の容器の場合には、前面部３０に補助折目３２を設ければ、前面部３０上に平坦に折畳んだ底面部２４を順に折り曲げながら内容物を上方に移動させてストローから外部に押し出すことができる。
また本発明は、前記上方三角突部２１、２１の両頂部２３、２３を通り、上面部３５に平行な第２水平折目３４を具えることを特徴とする。そのため、上方の三角突部２１，２１を側面部２５，２５から剥すことなく前面部に設けた第２水平折目３４を内側にして上面部３５の手前側半分を該前面部３０上に平坦状に折畳んで、内容物を外部に押し出すことができる。
また、本発明は、前記第２水平折目３４と上面部３５との間の距離ｄ２が上面部３５の幅Ｗ２の１／２であることを特徴とする。そのため、上面部３５の手前側部分が第２水平折目３４を内側にして前面部３０上に平坦状に折畳むことができる。
また本発明は、前記挿入部３６は上面部３５の後面部側に設けられており、前記第２水平折目３４は前面部３０を通ることを特徴とする。
また本発明は、粘度が1０ｍＰａ・ｓ以上の内容物が充填されていることを特徴とする。清涼飲料水などの場合は，粘度が低いので弱い吸引力でも吸引できるが、粘度の高い内容物例えばお粥などの場合は強い吸引力が出ないと内容物を吸引することが困難である。そのため本発明は、強い吸引力を必要とする例えば、１０ｍＰａ・ｓ以上の粘度の高い内容物を食する場合にも、吸引力を必要とせずに外部からの押圧力だけで容易に食することができる。
また、ストロー挿入用の挿入部３６を有した押圧変形可能な容器２０の該挿入部に着脱可能に装着されるストロー４ｂは、円管状のベース部１２と、前記容器の内面に係止してストローの脱出を防止する係止部６ａと、該係止部に隣接した少なくとも１個の通孔７ａとを有し、該通孔の開口面積の合計がベース部の直径方向断面積と同等以上である。
前記係止部６ａが、その外径が飲み口側から通孔側に向って漸減するテーパー部を有している。また前記係止部６ａがテーパー部の最大外径がベース部１２の外径とストロー管壁の厚さとの和より小さく、ベース部の外径より大きく設けてある。
【００１４】
本発明は、折畳可能な容器と粘度流体から成る内容物の流出を容易にするストローを具えた押圧変形可能な紙パック容器であって、押圧変形可能な容器の内容物を飲用するため、該容器の挿入部に刺し込んだストローを口で吸引しなくても、又は、吸引することができなくてもこの容器を平坦状に折畳めるように案内用の折目を設け、該容器を外側から押圧して平坦状に変形させて内容物をストローから外部に押し出すことができる。粘度の高い流体からなる内容物を飲用するには、強い吸込力を必要とするが、乳幼児や老人や病人など体力が無いため強い吸引力を出せない人でも、該容器を外方からの押圧力で内容物を外部に流出させて飲用することができる。

【発明を実施するための最良の形態】
【００１６】
以下、本発明の実施形態を添付した図面により詳細に説明する。
図5に示した押圧変形可能な容器２０について説明すると、内面に耐水薄膜１３（図１４）を設けた厚紙材を筒状に形成し、その上下端縁を密封して折り曲げて設けた方形箱型１５の対をなす両側面部２５，２５と、前面部３０及び後面部３８とを設け、該前面部及び後面部の上下を平坦に折畳んで左右に突出させて三角面部２１，２１、２２，２２をそれぞれ形成してある。下方の三角突部２２，２２は夫々下方に折り曲げて底面部２４の下面に接着結合させてある（図６）。さらに、上方の三角突部２１，２１は下方に折り曲げて側面部２５，２５に弱く加熱接着してある（図６）。
【００１７】
前記容器２０を構成する方形箱型１５に設けた対をなす側面部２５，２５の下方には、底面部２４の端縁である底辺部２６，２６と、該底辺部を底辺にして直角二等辺三角形の稜線の頂部を結んだ逆Ｖ型折目２７，２７とで設けた三角面部２７ａ、２７ａを設けてある。さらに、該逆Ｖ型折目の頂部２８，２８と側面部の中間部分に上下方向に設けた縦折目２９，２９とを連結し、縦折目２９，２９の上端は側面部の上端まで設けてある。さらに、前面部３０には下方から順に第１水平折目３１、補助折目３２，３３を底面部２４とそれぞれ平行に形成し、さらに、上面部３５にはストローを刺し込む挿入部３６を設けてある。
【００１８】
押圧変形可能な容器２０の上面を底面部２４と略平行な平坦にした上面部３５の左右に突出した三角突部２１，２１を下方に折り曲げて両側面部２５，２５に密着させるか、または、加熱加工により該三角突部２１，２１を該側面部に弱く接着させる。即ち、加熱温度または加熱時間を調整すれば接着強度を自由に調整することができる。具体的には、体力の弱い乳幼児や病人でも容易に三角突部２１，２１を剥すことができるように、接着強度を好ましくは１５Ｎ／１５ｍｍ以下、より好ましくは１０Ｎ／１５ｍｍとする。この三角突部２１，２１は、下方に折り曲げて側面部２５，２５に密着させ、その外側から例えば透明なフイルム４０で密封包装して、前記容器２０の上方に位置する側面部２５，２５を補強する。
【００１９】
図１５に示すように、前記容器２０を３個透明なフイルム４０で包装して１パックにまとめて取扱い易くする場合、該フイルムで上方の三角突部２１，２１を各側面部２５，２５に密着して該側面部の上方を補強する。また、前記容器２０が１個で、該容器の外側を透明フイルム４０で包装しない場合は、該三角突部２１，２１を側面部２５，２５に加熱加工により弱く接着して側面部２５，２５の上方を補強する。

【００２１】
内容物は、清涼飲料のように粘度が低いと吸引力が弱くても吸引できるが、お粥のようなゼリー状食品の粘度の上限は１００万ｍPａ・sであり、その下限は１０ｍＰａ・ｓ以上であることが適当である。即ち、このように粘度の濃い内容物の場合、病人や老人など強い吸引力でストローを吸引しないと内容物を食することはできないが、本発明では吸引力は必要なく、容器を外部から押圧することにより内容物を押し出すことができる。そのため、本人以外の介助者が容器を押圧して内容物を食ベさせることもできる。
【００２２】
容器の側面部２５，２５の下方に設けた逆Ｖ型折目２７，２７の該頂部２８，２８を通る水平線Ｓ、Ｓと前面部３０との交点を結んで底面部２４と平行な第１水平折目３１を前面部３０の下方に設けてあるため、容器の底面部２４の手前側の両角部Ｂ、Ｂを斜め上方に押圧すると、折目３１を内側にして該底面部の手前側略半分は前面部３０上に平担に折畳むことができる（図８）。第１水平折目３１を内側にして底面部２４の幅Ｗ１の手前部分の半分を前面部３０上に折畳むと、側面部２５，２５の下方部分は、逆Ｖ型折目２７，２７が折畳まれ外方に突出した頂部２８，２８を有する三角面部２７ａ，２７ａは底面部２４の両側外方に突出する。

【００２４】
底面部２４と平行に設けた第１水平折目３１は前面部３０に設けられ、該折目３１と底面部２４との距離は、底面部２４の横幅ｗ１の半分の長さｄ１の距離に設けてあるので、第１水平折目３１を内側にして折畳んだ底面部２４の手前側半分は、前面部３０上に平坦状に折畳まれる（図８）。
【００２５】
前記容器の前面部３０に設けた第１水平折目３１と平行で、且つ、底面部２４の横巾ｗ１と略同じ距離に補助折目３２を設け、さらに、容器２０が長い場合には必要に応じて第２の補助折目３３を設け、底面部２４を同一方向に順に折畳んで容器内の内容物を押し出すようにしてもよい（図１０）。
【００２６】
上記のように、両側面部２５，２５の中間部分に垂直方向に設けた縦折目２９，２９と、下方の逆Ｖ型折目２７，２７の頂部２８，２８とを連結して設けてあるので、上方の三角突部２１，２１を側面部２５，２５から離して略水平にした後（図６）、上方の両側端角部の各交点Ａ，Ａ，Ａ，Ａを外方から押圧して折畳み、また、下方の手前側の両角部Ｂ，Ｂを斜め上方に押圧すると、図８に示した第１水平折目３１を内側にして底面部２４は平坦状に折畳まれる。前面部３０には下方から夫々第１水平折目３１、補助折目３２，３３を設けてあるので、両側面部２５は前記縦折目２９を外方に突出して二つ折りに折畳んで平坦にすると共に、第１水平折目３１を内側にして底面部２４の幅ｗ１の手前側半分を前面部３０上に平坦状に折畳み、内容物を押し出すことができる。

本発明の他の実施形態を図１１に基づいて説明すると、容量が１００〜１２５ｍｌ程度の小型の押圧変形可能な容器２０ａは、図５と略同じ形状で折目が多少相違し、筒状に形成した厚紙材の上下端を密封して方形箱型１５に折り曲げて両側面部２５，２５と前面部３０と後面部３８とを設け、該方形箱型１５の上下を平坦に形成してある。前記容器２０ａの上下を左右に突出して設けた上下の三角突部２１，２１及び２２，２２（図８）をそれぞれ下方に折り曲げ、上方の三角突部２１，２１は側面部２５，２５に、また、下方の三角突部２２，２２は底面部２４の下面に夫々接着してある。なお、前記符号と同じ符号は同じものを表している。
【００２８】
方形箱型１５の下方には、底面部２４の端縁である底辺部２６を底辺にした直角二等辺三角形の稜線の頂部を結ぶ逆Ｖ型折目２７，２７の頂部２８，２８と、側面部２５，２５の中間に位置して垂直方向に設けた縦折目２９，２９とを連結してある。縦折目２９，２９の上部は上方の三角突部２１、２１の下部を通る水平線Ｔ、Ｔの一端と連結し、該水平線Ｔ、Ｔの他端と前面部３０との交点を結んで底面部２４と平行な第２水平折目３４を前面部３０に設けてある。また、前記逆Ｖ型折目２７，２７の頂部２８，２８を通る水平線Ｓ、Ｓと前面部３０の交点を結ぶ直線上に設けた第１水平折目３１を前面部３０の下方に設けてある。尚、上面部３５に設けた挿入部３６は図５と相違して容器耳部３５ａを有する側と反対側に形成し、容器耳部３５ａの手前側の上面部３５は第２水平折目３４を内側にして前面部３０上に折畳まれても、挿入口３６を有する側の上面部は該折目３４を内側にして折畳まれる側ではないので該挿入口に挿入したストローに無理な力は加わらない。
【００２９】
容器２０ａ内の内容物を食する場合、挿入部３６にストローを挿入し、該ストローの端部を口に咥えて該容器の前面部３０と後面部３８の上部両側を下方に、また、下部手前側両端を上方に外側から押圧すると、側面部２５、２５はその中間に設けた縦折目２９、２９が外方に突出して二つ折りに折畳まれて平坦状になり、内容物を挿入部３６に挿入したストローから外部に押し出すことができる。
【００３０】
容器２０ａは、前面部３０の上方に設けた第２水平折目３４と、下方に設けた第１水平折目３１を夫々内側にして折畳むと、上面部３５及び底面部２４は前面部３０上に平坦状になって容器を外部から押圧して内容物を外部に押し出すことができる。容器２０ａは、図１２、１３に示すように、底面部２４と上面部３５は平坦状になって前面部３０上に折畳まれ容器の内部は狭められる。この場合、前面部３０と後面部３８を外方から押圧すると、第２水平折目３４を内側にして上面部３５の幅Ｗ２の手前側半分は上面部３０上に折畳まれ、また、第１水平折目３１を内側にして底面部２４の手前側半分は前面部３０上に折畳まれ、該容器２０ａは平坦状に折畳まれる。容器の裏面図は、図１３に示すように後面部３８は平面状となり、容器は平坦状に押し潰されて吸引力を必要とすることなく外部からの押圧によってストロー４ｂから押し出すことができる。特に、容器が１００ｍｌ又は１２５ｍｌ程度の小型の場合には、前面部３０に図５に示すように補助折目３２，３３を設ける必要はない。このように第１の実施態様と異なり、三角突部２１，２１を側面部２５から剥す必要が無いので爪などを痛めることがないし、指先が自由にならない病人、老人、幼児などにとって便利である。
【００３１】
このように、容器２０を外側から押圧して平坦状に折畳むことにより、体力の弱い病人や老人や幼児などが吸込力を必要とすることなく粘度の高い内容物をストローから容器外部に押出して安心して食することができる。ここで、押圧変形可能な容器とは、紙パック容器で外部から押圧することにより平坦状に折畳まれる部材で形成した容器を意味している。
【００３２】
本発明の実施形態のストローについて説明すると、紙材や合成樹脂材により筒状に形成し、ストローの中間部には飲み口側から折曲可能な蛇腹部１０と先端側に向って漸減するテーパー部をした係止部と、係止部６ａに接して設けた通孔７ａと、先細筒１１と、開口部８ａとを夫々設けてある。このストローの先端に設けた先細筒１１は，挿入部３６に刺し込む際に，中心から少しずれて刺し込んでもテーパー部にガイドされ，正しく刺し込むことができる。この通孔７ａは、ストローの直径方向断面積と同等以上の開口面積を有している。ここで、開口面積とは、ストローの外周面を展開した平面上の面積をいう。即ち、ストローに設けた通孔の開口面積の大きさが該ストローの断面積未満の場合には、押し出しに要する力が過大となってしまうおそれがある。また、ストロ−強度を確保する観点から、通孔の開口面積はストローの断面積の3倍以下とすることが好ましい。
【００３３】
ストローの係止部６ａは、飲み口側から通孔７ａ側に向って外径を先細状になるようテーパー部に形成してある。そして、該係止部の最大外径はストローの外径とストローの管壁厚との和より小さいことが必要である。例えば、ストローの外径は６．３ｍｍであって、その管壁厚は１ｍｍであり、両者の和であるその最大外径の寸法は７．３ｍｍである。そして、係止部６の最大外径が数値７．３ｍｍ以上の場合には、ストローの係止部６ａを容器の挿入部３６に刺し込めないという製造上の問題が発生する。また、係止部６ａの最小外径は、ストロー外径６．３ｍｍより短いことが必要である。このように、係止部６ａに飲み口側から通孔側に向って漸減するテーパー部を設けてあるので挿入部３６に挿入しやすく、いったん挿入されると抜け難いという効果を有する。
【実施例】
【００３４】
紙パック容器２０の内部に粘性流体を３０ｍｌ詰め、該容器に一定の外圧５ｋＰａを加え、３０ｍｌの内容物が全て流出するまでの時間を計測すると、以下のような結果を得た。ここで、従来のストローの断面外径は５ｍｍまたは６ｍｍであり、管壁厚は１．０ｍｍである。之に対し、本発明のストローの外径は６．３ｍｍである。
従来のストロー ４秒
本発明のストロー ２秒
ストローを用いて粘性流体からなる内容物を飲用する場合、本発明に用いたストロー４ｂは、従来のストロー３に比べて半分の時間に短縮することができた。【Technical field】

INDUSTRIAL APPLICABILITY The present invention can drink juice, soft drinks, especially jelly foods, etc. contained in a paper pack container by external pressure without using suction force. With a straw The present invention relates to a press-deformable paper pack container.
[Background]
[0002]
As shown in FIG. 16, the paper pack container 1 containing various drinks such as milk, soft drinks, juices, and the like has an insertion part 2 for inserting a straw 3 for drinking various internal drinks on the upper surface part 9 of the container. The beverage is drunk from the upper end of the straw provided and inserted into the sealing film covering the insertion portion. Japanese Patent Application Laid-Open No. 2000-313435 discloses a straw 3 which is attached to the outer surface of the container 1 in a state where the tip 3 is inclined to facilitate insertion into the insertion portion 2 and is accommodated in the transparent bag 5.
[Patent Document 1]
JP 2000-313435 A
[0003]
The conventional straw 3 is formed longer than the height of the paper pack container 1 and is attached obliquely to the outside of the container, and the tip inserted into the insertion part 2 has a length that reaches the bottom of the container. Even if it falls, the tip of the straw reaches the bottom, so that the container can be tilted to drink without leaving any stuffed contents. However, when the straw inserted into the insertion part 2 is sucked into the mouth and sucked or transferred to other baby bottles or cups, the contents are gradually reduced in pressure when the contents flow out to the outside. Since no matter comes out, it is necessary to increase the internal pressure by pressing the container from the outside.
[0004]
If the container whose contents have been reduced by drinking is inverted, the tip of the straw is exposed from the drink and the contents cannot be drunk. Also, since the straw 3 has the same shape and is simply inserted into the insertion portion 2, if it is accidentally pulled outward, it will easily come out of the insertion portion 2, and the contents will flow out of the container and contaminate clothes, etc. There was a fear. Thus, the straw which improved in view of the problem which the conventional straw has is shown by Unexamined-Japanese-Patent No. 2002-249172 and Unexamined-Japanese-Patent No. 2002-355161.
[0005]
As shown in FIG. 1, the improved straw 4a to be inserted into the insertion portion 36 provided in the press-deformable container 20 made of paper or the like has an arbitrarily shaped locking at a substantially intermediate portion so as not to be inserted into the container more than a certain amount. A portion 6 is provided and is hooked to the insertion portion 36. A through hole 7 is provided at a position approximately spaced from the locking portion 6 by the same thickness as the thickness W of the material forming the container 20, and an oblique opening 8 is provided at the end of the straw. One or more through holes 7 may be provided. The beverage in the container can be drunk out of the through hole 7 in addition to the opening 8 of the straw.
[0006]
When transferring the contents from the straw-4a inserted into the insertion portion 36 to a cup or baby bottle, one or two or more through holes 7 are provided close to the straw locking portion 6, so that the inside of the container 20 The beverage can be taken from the opening 8 or the through-hole 7 and transferred to another container. In this case, in the case of a conventional long straw, when the beverage in the container is reduced, the tip of the straw is exposed outside the beverage and the contents cannot be drunk, but the straw 4a shown in FIG. 1 has an opening 8 provided at the tip. In addition, since the through-hole 7 is provided close to the wall surface of the container 20, the contents can be drunk or transferred to the end if the container is turned upside down (FIG. 14).
[0007]
2-4 using the principle of the improved straw 4a, the tip of another improved straw-4b shown in FIGS. 2 to 4 is inclined to the tip of the tapered tube 11 which is tapered to facilitate insertion into the insertion portion 36 provided in the container. In the middle part, the outer diameter is substantially tapered so that the bellows part 10 that can be expanded and contracted within a certain range and the straw 4b inserted into the insertion part 36 do not easily escape. A locking portion 6a and a step portion 6b having a stopper function are provided, and a through hole 7a is provided close to the locking portion. The straw shown in FIG. 3 has a step portion 6b perpendicular to the maximum outer diameter portion of the locking portion 6a provided on the outer peripheral surface of the straw, and the straw shown in FIG. 4 is formed on the maximum outer diameter portion of the locking portion 6a. A step portion 6b provided vertically from the end of the cylindrical portion 6c having a continuous reinforcing function is provided continuously to the base portion 12 of the straw outer peripheral surface.
[0008]
When the contents of the container 20 decrease and the opening 8a at the tip of the straw 4b is exposed outside the beverage (FIG. 14), the contents enter the straw through the through hole 7a. That is, if the bottom portion of the container 20 is faced upward and the stro-4b inserted into the insertion portion 36 is sucked into the mouth, it can be drunk to the end. In addition, when transferring the contents to a cup or baby bottle, even if the remaining amount is reduced and the opening 8a of the straw is exposed outside the beverage, the contents can be taken in from the through-hole 7a, so that it can be transferred to another container. it can.
[0009]
A typical conventional paper pack container 1 is shown in FIG. 16. A cardboard material having a water-resistant thin film 13 (FIG. 14) such as aluminum foil or polyethylene resin formed on the inner surface is formed into a cylindrical shape, and its upper and lower edges Are bent into a square box shape, and the triangular protrusions protruding from the upper, lower, left and right sides of the both side portions are bent downward, and adhesively bonded to the side surface portion and the bottom surface portion to assemble the whole into a rectangular box shape.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0010]
The water-resistant film that seals the insertion portion 2 provided on the upper surface portion 9 of the paper pack container 1 comes into close contact with the outer peripheral surface of the straw when the straw 3 is inserted and seals the straw against the outside. If it is sucked and sucked, the container is pressed and deformed by the negative pressure generated inside the container 1 in accordance with the decrease in the contents. Thereafter, when the mouth is released from the straw 3, the outside air is taken into the interior by the negative pressure and the original state is restored. The straw is again sucked into the mouth and sucked, and the contents are drunk while being repeated. In general, the contents in a container are usually drunk by suction while holding a straw in the mouth.
[0011]
However, in the case of the contents of a viscous fluid having a viscosity such as a jelly drink instead of an aqueous solution such as a soft drink, a strong suction force is required for drinking with a straw. Therefore, it is difficult to drink the contents because a strong suction force cannot be produced if the physical strength is weak such as infants, sick people, and elderly people.
In addition, there is a container that pushes out a jelly beverage while it is squeezed while holding a squeezable container formed by a soft resin member, for example, a flexible member such as polyethylene or aluminum foil. In this case, suction force is not required, but it requires a strong force of narrowing down, and the material cost of the container is high, and in addition, the container after drinking has to be sorted, so it takes time to dispose of waste. There was a problem such as this.
[0012]
The present invention is a paper pack that can be pressed and folded from the outside of a press-deformable paper pack container, the contents of the contents can be drunk to the end without requiring suction, and can be transferred to another container. The object is to provide containers and straws.

Below the pair of side surface portions 25, 25 provided in the rectangular box shape 15 constituting the container 20, there are bottom side portions 26, 26 which are the edges of the bottom surface portion 24, and two perpendicular directions with the bottom side portion as the bottom side. Triangular surface portions 27a, 27a provided by inverted V-shaped folds 27, 27 connecting the tops of equilateral triangular ridge lines are provided. Further, the tops 28, 28 of the inverted V-shaped folds and vertical folds 29, 29 provided in the vertical direction are connected to the middle part of the side surface, and the upper ends of the vertical folds 29, 29 extend to the upper end of the side surface. It is provided. Further, a first horizontal fold 31 and auxiliary folds 32 and 33 are formed in the front portion 30 in order from the bottom in parallel with the bottom portion 24, and an insertion portion 36 for inserting a straw is provided on the upper portion 35. It is.
[0018]
Triangular protrusions 21 and 21 projecting left and right of a flat top surface portion 35 whose upper surface of the deformable container 20 is substantially parallel to the bottom surface portion 24 are bent downward to be in close contact with the side surface portions 25 and 25, or The triangular protrusions 21 and 21 are weakly bonded to the side surfaces by heat processing. That is, the adhesive strength can be freely adjusted by adjusting the heating temperature or the heating time. Specifically, the adhesive strength is preferably 15 N / 15 mm or less, more preferably 10 N / 15 mm so that even the infants and sick who have weak physical strength can easily peel the triangular protrusions 21 and 21. The triangular protrusions 21 and 21 are bent downward and brought into close contact with the side surfaces 25 and 25, and sealed and packaged with, for example, a transparent film 40 from the outside, so that the side surfaces 25 and 25 positioned above the container 20 are formed. Reinforce.
[0019]

A second horizontal fold line 34 parallel to the portion 24 is provided in the front surface portion 30. Further, a first horizontal fold 31 provided on a straight line connecting the intersection of the horizontal line S passing through the top portions 28 and 28 of the inverted V-shaped folds 27 and 27 and the front surface portion 30 is provided below the front surface portion 30. is there. In addition, the insertion part 36 provided in the upper surface part 35 is formed in the opposite side to the side which has the container ear | edge part 35a unlike FIG. 5, and the upper surface part 35 of the near side of the container ear part 35a is the 2nd horizontal fold 34. Even if it is folded on the front surface portion 30 with the inner side facing inward, the upper surface portion on the side having the insertion port 36 is not the side that is folded with the fold line 34 on the inner side. No power is added.
[0029]
When the contents in the container 20a are eaten, a straw is inserted into the insertion portion 36, the end of the straw is held in the mouth, the upper sides of the front portion 30 and the rear portion 38 of the container are directed downward, and the lower portion When the both ends on the front side are pressed upward from the outside, the side folds 29, 29 project outward and are folded in two into a flat shape, and the contents are inserted. It can be pushed out from the straw inserted into the portion 36.
[0030]
When the container 20a is folded with the second horizontal fold line 34 provided above the front surface part 30 and the first horizontal fold line 31 provided below the inner side, the upper surface part 35 and the bottom surface part 24 become the front surface part 30. It becomes flat on the top and the container can be pushed from the outside to push the contents out. As shown in FIGS. 12 and 13, the container 20 a is flat on the bottom surface 24 and the top surface 35 and folded on the front surface 30 to narrow the inside of the container. In this case, when the front surface portion 30 and the rear surface portion 38 are pressed from the outside, the front half of the width W2 of the upper surface portion 35 is folded on the upper surface portion 30 with the second horizontal fold 34 being inward, The front half of the bottom surface portion 24 is folded on the front surface portion 30 with the one horizontal fold 31 inside, and the container 20a is folded flat. In the rear view of the container, as shown in FIG. 13, the rear surface portion 38 is flat, and the container is crushed flat and can be pushed out of the straw 4b by external pressure without requiring suction force. In particular, when the container is as small as about 100 ml or 125 ml, it is not necessary to provide the auxiliary folds 32 and 33 on the front face 30 as shown in FIG. Thus, unlike the first embodiment, it is not necessary to peel the triangular protrusions 21 and 21 from the side surface portion 25, so that the nails and the like are not damaged, and it is convenient for sick people, elderly people, infants and the like whose fingertips are not free. .
[0031]
In this way, by pressing the container 20 from the outside and folding it into a flat shape, a sick person with weak physical strength, an elderly person, an infant, and the like push out a high-viscosity content from the straw to the outside of the container without requiring suction. You can eat with confidence. Here, the press-deformable container means a container formed of a member that is folded flat by being pressed from the outside with a paper pack container.
[0032]
The straw of the embodiment of the present invention will be described. The straw is formed into a cylindrical shape from paper material or synthetic resin material, the bellows portion 10 that can be bent from the drinking mouth side at the middle portion of the straw, and the taper that gradually decreases toward the tip side. There are provided a locking portion having a portion, a through hole 7a provided in contact with the locking portion 6a, a tapered tube 11, and an opening 8a. The tapered cylinder 11 provided at the tip of the straw is guided by the taper portion even when it is slightly displaced from the center when inserted into the insertion portion 36, and can be inserted correctly. The through-hole 7a has an opening area equal to or larger than the diameter direction cross-sectional area of the straw. Here, the opening area means an area on a plane where the outer peripheral surface of the straw is developed. That is, if the size of the opening area of the through hole provided in the straw is less than the cross-sectional area of the straw, the force required for extrusion may be excessive. Further, from the viewpoint of securing the straw strength, it is preferable that the opening area of the through hole is not more than 3 times the cross-sectional area of the straw.
[0033]
The straw locking portion 6a is formed in a tapered portion so that the outer diameter tapers from the drinking mouth side toward the through hole 7a side. The maximum outer diameter of the locking portion needs to be smaller than the sum of the outer diameter of the straw and the tube wall thickness of the straw. For example, the outer diameter of the straw is 6.3 mm, the tube wall thickness is 1 mm, and the dimension of the maximum outer diameter, which is the sum of both, is 7.3 mm. And when the maximum outer diameter of the latching | locking part 6 is a numerical value 7.3 mm or more, the manufacturing problem that the latching | locking part 6a of a straw cannot be stabbed in the insertion part 36 of a container generate | occur | produces. Moreover, the minimum outer diameter of the latching | locking part 6a needs to be shorter than straw outer diameter 6.3mm. As described above, the locking portion 6a is provided with the tapered portion that gradually decreases from the drinking mouth side toward the through hole side, so that it can be easily inserted into the insertion portion 36, and once inserted, it is difficult to come off.
