Description

【０００１】
【発明の属する技術分野】
この発明は、例えば玩具や文房具、雑貨品、化粧品、食品、薬品（錠剤を含む）、電子部品等の被収容物をブリスターパック包装するときに用いられる連続的成形品の巻回方法及びその巻回装置及び連続的成形品に関する。
【０００２】
【従来の技術】
従来、上述の被収容物をブリスターパック包装する方法としては、例えば被収容物が収容される凹状の収容部を、成形シート全長に対して所定間隔に隔てて形成すると共に、被収容物を、成形シートに形成した各収容部に対して個々に収容し、例えば台紙やアルミ箔等の封函シートを、成形シートの後面側全長に対して接着固定又は加熱固定した後、被収容物が収容されたブリスターパックに分離する特許文献１のブリスター包装機がある。
【０００３】
【特許文献１】
特開平１１−３１４６１６号公報。
【０００４】
【発明が解決しようとする課題】
しかし、上述の収容部が形成された成形シートを渦巻状に巻回した場合、内周側に巻回される収容部及び外周側に巻回される収容部の巻回位置にズレが生じるので、渦巻状に巻回される成形シートの外径が徐々に大きくなるだけでなく、嵩張るため、運搬及び輸送、保管するときに広いスペースが必要であり、取扱い及び管理に手間が掛かる。且つ、各収容部が嵌合したまま変形すると、機械的に分離することが難しく、作業者の手で分離しなければならないため、作業能率が悪くなるという問題点を有している。
【０００５】
且つ、内周側の収容部に付与される応力が大きいので、例えば変形するか、押し潰されるか、皺が付いたりする等して、成形時の形態を保持することが難しく、ブリスターパックとして商品価値が損なわれるだけでなく、被収容物を収容部に対して確実に収容することが困難である。且つ、例えば食品や薬品等のような多数の被収容物を収容するときはよいが、被収容物の数量が少ない場合、装置及び設備が高価であるため、包装コストが高くなるという問題点を有している。
【０００６】
この発明は上記問題に鑑み、凹状の収容部が形成された連続的成形品を略螺旋方向に巻回して、先行及び続いて巻回される各収容部を互いに嵌合することにより、運搬及び輸送、保管するときのスペースが小さくて済み、被収容物を収容する作業の省力化及び能率アップを図ることができる連続的成形品の巻回方法及びその巻回装置及び連続的成形品の提供を目的とする。
【０００７】
【課題を解決するための手段】
この発明は、被収容物を収容する凹状の収容部が長さ方向に対して所定間隔に隔てて形成された帯状の成形シートを略螺旋方向に巻回すると共に、上記収容部が形成された成形品の間を略螺旋方向に対して巻回が許容される方向に変形して、該略螺旋方向に対して先行して巻回される成形品の収容部と、続いて巻回される成形品の収容部とを互いに嵌合して略螺旋状に巻回する連続的成形品の巻回方法であることを特徴とする。
【０００８】
上述の被収容物は、例えば玩具や文房具、雑貨品、化粧品、食品、薬品（錠剤を含む）、電子部品等で構成される。また、帯状の成形シートは、例えば透光性又は不透光性を有するプラスチックシート、紙製シート、金属製シート、プラスチック及び紙、金属等を複合した複合シートで構成される。
【０００９】
また、成形品は、例えば被収容物を、成形シートを分割してなる成形品に形成した凹状の収容部に収容し、例えば台紙やアルミ箔、その他の箔体等の封函シートを、成形品の後面側に装着して、成形品及び封函シートの対向面を接着剤で接着固定するか、相互の対向面を加熱固定する等して構成することができる。また、被収容物を、成形品に形成した凹状の収容部に収容し、封函シートを、成形品の周縁部（例えば両方縁部、一方縁部を除く三方縁部、四方縁部）に折り曲げ加工した折曲げ部に沿ってスライド挿入するか、成形品及び封函シートを互いに嵌着固定するか、相互の対向面を係止固定する等して構成することができる。また、被収容物を、成形品を構成する前面部及び後面部の何れか一方又は両方に形成した凹状の収容部に収容し、一体的に成形した前面部及び後面部を、相互の折曲げ部分に形成したミシン目や折り曲げ罫線に沿って相対向する方向に折り曲げ、前面部及び後面部の対向面又は対向縁部を、接着剤で接着固定するか、凹部及び凸部を互いに嵌着固定するか、止め具で固定する等して構成することもできる。
【００１０】
また、成形品を、例えば展示部や棚部、壁部、柱部等の吊下げ部に吊下げるための係止部（例えば孔部やフック、溝部等）を設けて展示するか、起立状態に支持する脚部を設けて自立させることもできる。
【００１１】
また、凹状の収容部を、例えば一つ又は複数の被収容物が収容保持される大きさ及び形状に形成することができる。且つ、収容部及び成形品の外観を、例えば平面から見て略円形や略矩形、略楕円形等のような被収容物の外観と略対応する形状に形成してもよい。
【００１２】
また、一つ又は複数の収容部が形成された成形品を長さ方向に連続して成形してなる連続的成形品を、例えば略鉛直方向や略垂直方向、略水平方向等の所望する方向に対して略螺旋状に巻回することができる。且つ、その巻回形状を、例えば軸芯方向から見て略円形や略楕円形、略三角形、略四角形、略六角形、その他の多角形等の所望する形状に巻回してもよい。
【００１３】
且つ、連続的成形品の巻回例として、例えば単一の成形品が連続して形成された連続的成形品を巻回するか、複数（例えば２個又は２個以上）の成形品を１組として巻回するか、複数（例えば２個又は２個以上）の成形品を１組として巻回方向と略直交する方向に配列すると共に、一端側に配列した成形品を内側となるように巻回してもよい。
【００１４】
また、成形品の間（対向縁部及び対向端部を含む）を連結する連結部を、例えば略螺旋方向に対して巻回が許容される方向に変形可能な幅や肉厚、形状等に形成するか、その巻回が許容される方向に対して折曲げ可能及び伸縮可能、可撓可能な柔軟性を有する材質で形成する等してもよい。
【００１５】
また、連結部を、例えば略Ｕ字状や略Ｖ字状等の連結形状に形成するか、略Ｕ字状や略Ｖ字状等の断面形状を有する蛇腹形状や薄肉の肉厚に形成するか、巻回方向に対して伸張可能及び拡張可能に形成することができる。また、連結部を、成形品の間に対して部分的（一箇所又は複数箇所）に形成するか、全体的に形成することもできる。
【００１６】
また、例えば切れ目や溝部、ミシン目等を、成形品の間（対向縁部及び対向端部を含む）に対して巻回方向及び連結方向と略直交する方向に形成すると共に、略螺旋方向に対して巻回が許容される方向に変形可能（伸張可能及び拡張可能を含む）な連結部を成形品の間に対して部分的（連結部が残る状態）に形成するか、成形品の外周部分を、例えば打抜き加工や切抜き加工等の加工方法により連結部が残る状態に分離して形成してもよい。
【００１７】
また、単一又は複数の成形品を成形した後、例えば打抜き加工や切抜き加工等の加工方法により分離した成形品の間を、例えばテープやシート、箔体、膜体等の帯体、或いは、糸や紐、合成樹脂フィラメント等の線条体で巻回方向に対して変形可能に連結することもできる。なお、上述の成形品を、例えば一体的又は連続的に成形された複数の成形品を単体に分離するか、単一の成形品を独立して成形する等してもよい。
【００１８】
つまり、一つ又は複数の被収容物を収容する凹状の収容部が長さ方向に対して所定間隔に隔てて形成された帯状の成形シートを略螺旋方向に巻回するとき、収容部が形成された成形品の間を略螺旋方向に対して巻回が許容される方向に変形して、略螺旋方向に対して先行して巻回される成形品の収容部と、続いて巻回される成形品の収容部とを互いに嵌合して略螺旋状に巻回した状態に保持する。
【００１９】
実施の形態として、被収容物を収容する凹状の収容部が長さ方向に対して所定間隔に隔てて形成された帯状の成形シートを略螺旋方向に巻回すると共に、上記収容部が形成された成形品の間を略螺旋方向に対して巻回が許容される方向に変形して、該略螺旋方向に対して先行して巻回される成形品の収容部と、続いて巻回される成形品の収容部とを互いに嵌合する巻回手段を備えることができる。また、上記巻回手段の前段に、上記凹状の収容部を成形シート全長に対して所定間隔に隔てて形成する成形手段を備えることができる。また、上記巻回手段の後段に、上記略螺旋状に巻回された連続的成形品の先行側収容部と後続側収容部との嵌合を解除し、該連続的成形品の嵌合解除側を次工程に供給する巻回解除手段を備えることができる。
【００２０】
且つ、上述の巻回手段は、例えばモータやその他の駆動手段で巻回方向に回転される回転台、その他の保持台等の巻回装置で構成される。また、成形手段は、例えば真空成形機や圧空成形機、加圧成形機、ブロー成形機等の成形装置で構成される。また、巻回解除手段は、例えばモータやその他の駆動手段で巻回方向に回転される回転台、その他の保持台等の供給装置と、気体（エアーやガス、雰囲気等）、液体（アルコールや蒸留水、揮発性液等）等の流体を上下成形品の間に吹き込むか、治具や肉厚の薄い部材等の分離具を上下成形品の間に差し込むか、負圧発生装置が発生する負圧で吸着するか、粘着材の粘着力で粘着する等して連続的成形品を巻き解き又は巻き戻しする分離手段とで構成される。且つ、次工程は、例えば被収容物を収容部に収容する収容工程と、連続的成形品の後面側を封函シートで封函する封函工程と、被収容物が収容された成形品に分離する分離工程等で構成される。
【００２１】
また、被収容物が収容される凹状の収容部を成形シート全長に対して所定間隔に隔てて形成し、上記収容部が形成された成形品の間を略螺旋方向に対して巻回が許容される方向に変形可能な連結部で連結した連続的成形品を構成することができる。
【００２２】
【作用及び効果】
この発明によれば、凹状の収容部が形成された連続的成形品を略螺旋方向に巻回すると共に、先行して巻回される収容部と、続いて巻回される収容部とを互いに嵌合するので、従来例のように変形及び押し潰されたり、皺が付いたりすることがなく、収容部に付与される応力が分散されるため、成形時の形態を保持することができ、成形品としての商品価値が損なわれず、被収容物を収容する作業が確実に行える。且つ、渦巻状に巻回するよりも嵩張らず、運搬及び輸送、保管するときのスペースが小さくて済み、取扱い及び管理が容易に行える。
【００２３】
且つ、収容部を、成形時の形態に保持したまま巻回するので、略螺旋状に巻回された連続的成形品を巻き解き及び巻き戻しする作業が容易に行え、連続的成形品を供給する作業及び被収容物を収容する作業を機械的に実行することが可能であり、作業の省力化及び能率アップを図ることができる。且つ、人為的な作業介入がないので、成形品の包装及び保管が衛生的に行える。
【００２４】
【実施例】
この発明の一実施例を以下図面に基づいて詳述する。
【００２５】
図面は、被収容物を、ブリスターパック包装するときに用いられる連続的成形品の巻回方法及びその巻回装置及び連続的成形品を示し、図１及び図３に於いて、この連続的成形品Ｂを成形する工程は、一つ又は複数の被収容物Ｅが収容される凹状の収容部Ｃａを、透光性（又は不透光性）のプラスチックシートＡ全長に対して所定間隔に隔てて形成する成形装置２を成形工程ａに設け、連続的成形品Ｂを略螺旋状に巻回する巻回装置３を成形工程ａ後段の巻回工程ｂに設け、略螺旋状に巻回した連続的成形品Ｂを巻解き供給及び巻戻し供給する供給装置４を巻回工程ｂ後段の供給工程ｃに設け、一つ又は複数の被収容物Ｅを連続的成形品Ｂの収容部Ｃａ…に収容する収容装置５を供給工程ｃ後段の収容工程ｄに設け、連続的成形品Ｂ及び収容部Ｃａ…の後面側に封函シートＤで封函する封函装置６を収容工程ｄ後段の封函工程ｅに設け、一つ又は複数の被収容物Ｅが収容された一つの成形品Ｃに分離する分離装置７を封函工程ｅ後段の分離工程ｆに設けて構成している。
【００２６】

【００２７】
且つ、収容部Ｃａ及び成形品Ｃの外観を、例えば平面から見て略円形や略矩形、略楕円形等のような被収容物Ｅの外観と略対応する形状に形成してもよい。また、プラスチックシートＡの代わりに、例えば紙製シート、金属製シート、プラスチック及び紙、金属等を複合した複合シートで構成することもできる。

【００３０】
且つ、（チ）に示すように、単一又は複数の成形品Ｃを成形した後、例えば打抜き加工や切抜き加工等の加工方法により分離した成形品Ｃ…の間を、例えばテープやシート、箔体、膜体等の帯体、或いは、糸や紐、合成樹脂フィラメント等の線条体で巻回方向に対して変形可能に連結することもできる。なお、上述の成形品Ｃを、例えば一体的又は連続的に成形された複数の成形品Ｃを単体に分離するか、単一の成形品Ｃを独立して成形する等してもよい。
【００３１】
前述の巻回装置３は、成形工程ａ後段に設けた巻回工程ｂに配設され、上述の成形工程ａから供給される連続的成形品Ｂを、成形品Ｃ…間の連結部Ｃｂ…を内側にして、モータ３ｂの駆動力により巻回方向に回転される略鉛直状態の回転台３ａに対して略螺旋方向に巻回すると共に、先行して下位側に巻回される成形品Ｃの収容部Ｃａと、続いて上位側に巻回される成形品Ｃの収容部Ｃａとを、図８にも示すように上下に嵌合して略螺旋状に巻回した後、所定長さ巻回された略螺旋状の連続的成形品Ｂを回転台３ａから取り外して、巻回工程ｂ後段に設けた供給工程ｃの供給装置４に供給する。また、連続的成形品Ｂを、例えば略垂直状態又は略水平状態に軸支した回転台３ａで巻回することもできる。
【００３２】
且つ、略螺旋状に巻回された連続的成形品Ｂを、次の収容工程ｄ（収容工場や収容場所も含む）に供給及び運搬する場合、下位側成形品Ｃの収容部Ｃａ及び上位側成形品Ｃの収容部Ｃａを互いに嵌合して略螺旋状に巻回した状態を保持するので、例えば巻芯や巻軸等を用いる必要がなく、また、不要な場合が多くなるため、略螺旋状に巻回された連続的成形品Ｂを回転台３ａから取り外して、例えば箱体や袋体等に収容して運搬及び輸送することができ、輸送費及び運搬費のコスト低減が図れる。
【００３３】

【００３５】
前述の供給装置４は、図３、図４に示すように、巻回工程ｂ後段に設けた供給工程ｃに配設され、上述の巻回工程ｂから供給される連続的成形品Ｂを、モータ４ｂの駆動力により巻解き方向及び巻戻し方向に回転される略鉛直状態の回転台４ａに対して装填保持すると共に、例えば気体（エアーやガス、雰囲気等）、液体（アルコールや蒸留水、揮発性液等）等の流体を巻き解き開始側又は巻き戻し開始側に巻回された上下成形品Ｃの間に吹き込むか、治具や肉厚の薄い部材等の分離具を上下成形品Ｃの間に差し込むか、負圧発生装置が発生する負圧で吸着するか、粘着材の粘着力で粘着する等して分離し、巻解き方向及び巻戻し方向に回転される連続的成形品Ｂを上端側から順に巻き解いて又は巻き戻して、供給工程ｃ後段に設けた収容工程ｄの収容装置５に対して連続送り供給又は間欠送り供給する。
【００３６】
また、連続的成形品Ｂを、例えば略垂直状態又は略水平状態に軸支した回転台４ａに装填保持し、その回転台４ａに装填された連続的成形品Ｂを下端側や一端側（左端や右端）から順に巻き解いて又は巻き戻して、収容工程ｄの収容装置５に供給することもできる。
【００３７】
前述の収容装置５は、供給工程ｃ後段に設けた収容工程ｄに配設され、上述の供給工程ｃから供給される連続的成形品Ｂの収容部Ｃａ…を収容位置に対して連続送り供給又は間欠送り供給し、収容位置上部に設けた被収容物供給部５ａから供給される被収容物Ｅ…を収容部Ｃａ…に対して個々に収容及び投入し、収容工程ｄ後段に設けた封函工程ｅの封函装置６に対して連続送り供給又は間欠送り供給する。また、複数の被収容物Ｅが収容される大きさ及び形状に形成した収容部Ｃａに、その複数の被収容物Ｅを一括して収容してもよい。
【００３８】
前述の封函装置６は、収容工程ｄ後段に設けた封函工程ｅに配設され、シート供給部６ａから供給されるロール状に巻回した封函シートＤ（例えば台紙やアルミ箔等）を、封函工程ｅに供給される連続的成形品Ｂの後面側に対して長さ方向に連続して装着すると共に、連続的成形品Ｂ及び封函シートＤの対向面を、一方又は両方の面に塗布した接着剤で接着固定して、封函工程ｅ後段に設けた分離工程ｆの分離装置７に対して連続送り供給又は間欠送り供給する。
【００３９】
且つ、ロール状に巻回された封函シートＤを、成形品Ｃの後面側が覆われる大きさ及び形状に分離して装着するか、予め成形品Ｃの後面側が覆われる大きさ及び形状に分離した封函シートＤを個々に装着するか、成形品Ｃ及び封函シートＤの対向面を熱溶着して固定するか、凹部及び凸部を互いに嵌着して固定するか、止め具で固定する等して封函することもできる。また、封函シートＤは、例えば少なくとも収容部Ｃａが覆われる大きさに及び形状に形成する。
【００４０】
前述の分離装置７は、封函工程ｅ後段に設けた分離工程ｆに配設され、上述の収容工程ｄから供給される連続的成形品Ｂを、例えば切断加工や打抜き加工、切抜き加工等の分離手段により一つ又は複数の成形品Ｃに分離する。つまり、成形品Ｃを連結する連結部Ｃｂを、例えば回転刃や固定刃等の切断具で切断或いは引き千切る等して、図８に示すように、一つ又は複数の被収容物Ｅが収容された一つの成形品Ｃに分離する。また、複数の成形品Ｃを１組にして分離してもよい。或いは、切断加工に代わる方法として、例えば打抜き加工するか、切抜き加工する等して分離してもよい。
【００４１】
図示実施例は上記の如く構成するものにして、以下、連続的成形品Ｂを成形及び巻回する方法と、被収容物Ｅを収容する方法とを説明する。
【００４２】
先ず、成形工程ａにおいて、図１、図２に示すように、ロール状に巻回された帯状のプラスチックシートＡを成形装置２に供給し、被収容物Ｅが収容及び保持される凹状の収容部ＣａをプラスチックシートＡ全長に対して所定間隔に隔てて形成すると共に、図５、図６に示すような、略螺旋方向に対して巻回が許容される方向に変形可能な連結部Ｃｂを、収容部Ｃａが形成された成形品Ｃ…の間（対向端部）に対して部分的に形成して巻回工程ｂの巻回装置３に供給する。
【００４３】
次に、巻回工程ｂにおいて、上述の成形工程ａから供給される連続的成形品Ｂを、成形品Ｃ…間の連結部Ｃｂ…を内側にして巻回装置３の回転台３ａに対して略螺旋方向に巻回すると共に、先行して下位側に巻回される成形品Ｃの収容部Ｃａと、続いて上位側に巻回される成形品Ｃの収容部Ｃａとを、図８にも示すように上下に嵌合しながら略螺旋状に巻回する。
【００４４】
且つ、所定長さ巻回する作業が完了後、略螺旋状に巻回した連続的成形品Ｂを回転台３ａから取り外して供給工程ｃの供給装置４に供給する。つまり、下位側成形品Ｃの収容部Ｃａ及び上位側成形品Ｃの収容部Ｃａを互いに嵌合して略螺旋状に巻回した状態を保持するので、例えば巻芯や巻軸等を用いる必要がなく、また、不要な場合が多くなるため、略螺旋状に巻回された連続的成形品Ｂの輸送費及び運搬費のコスト低減が図れる。
【００４５】
次に、供給工程ｃにおいて、図３、図４に示すように、略螺旋状に巻回した連続的成形品Ｂを、供給装置４の回転台４ａに装填して巻解き方向及び巻戻し方向に回転すると共に、例えばエアーやガス等の気体を、巻き解き開始側又は巻き戻し開始側に巻回された図８に示す上下成形品Ｃの対向面間に吹き込んで分離し、連続的成形品Ｂを上端側から順に巻き解いて又は巻き戻して、収容工程ｄの収容装置５に供給する。
【００４６】
次に、収容工程ｄにおいて、上述の供給工程ｃから供給される連続的成形品Ｂの収容部Ｃａ…を収容装置５の収容位置に供給し、被収容物供給部５ａから供給される被収容物Ｅ…を収容部Ｃａ…に対して個々に収容及び投入し、封函工程ｅの封函装置６に供給する。
【００４７】
次に、封函工程ｅにおいて、上述の収容工程ｄから供給される連続的成形品Ｂの収容部Ｃａ…を、封函装置６の収容位置に供給すると共に、ロール状に巻回された帯状の封函シートＤ（例えば台紙やアルミ箔等）を連続的成形品Ｂの後面側に対して長さ方向に連続して装着し、連続的成形品Ｂ及び封函シートＤの対向面を、一方又は両方の面に塗布した接着剤により接着固定して封函し、分離工程ｆの分離装置７に供給する。
【００４８】
また、ロール状に巻回された封函シートＤを、成形品Ｃ…の後面側が覆われる大きさ及び形状に分離して装着するか、予め成形品Ｃ…の後面側が覆われる大きさ及び形状に分離した封函シートＤを個々に装着することもできる。且つ、成形品Ｃ及び封函シートＤの対向面を熱溶着して固定するか、凹部及び凸部を互いに嵌着して固定するか、止め具で固定する等して封函することもできる。
【００４９】
次に、分離工程ｆにおいて、上述の封函工程ｅから供給される成形品Ｃ…を、分離装置７の分離位置に供給すると共に、成形品Ｃ…の間を連結する連結部Ｃｂ…を、例えば回転刃や固定刃等の切断具で切断或いは引き千切って、図９に示す被収容物Ｅが収容された一つ又は複数の成形品Ｃに分離する。また、例えば打抜き加工するか、切抜き加工する等して分離してもよい。
【００５０】
分離後において、被収容物Ｅが収容された一つの成形品Ｃ又は複数１組の成形品Ｃを包装処理（例えば箱詰め処理や袋詰め処理）した後、例えば温度管理した場所や貯蔵庫、倉庫等の保管場所に保管するか、或いは、例えば問屋や販売店、大型店等に出荷する。
【００５１】
一方、成形時において、例えば孔部やフック、溝部等の係止部を成形品Ｃ上部に設けるか、起立状態に支持する脚部を成形品Ｃ下部に設けることで、販売時において、被収容物Ｅが収容された成形品Ｃを、例えば展示部や棚部、壁部、柱部等の吊下げ部に吊下げ展示するか、起立状態に自立展示する等して販売することができる。また、複数の成形品Ｃを１組として一体的に連結したまま展示及び販売することもできる。
【００５２】
以上のように、プラスチックシートＡ全長に対して凹状の収容部Ｃａが所定間隔に隔てて形成された連続的成形品Ｂを略螺旋方向に巻回すると共に、先行して巻回される収容部Ｃａと、続いて巻回される収容部Ｃａとを互いに嵌合するので、収容部Ｃａが変形及び押し潰されたり、皺が付いたりすることがなく、収容部Ｃａに付与される応力が分散されるため、成形時の形態を保持することができると共に、成形品Ｃとしての商品価値が損なわれず、被収容物Ｅを収容する作業が確実に行える。且つ、渦巻状に巻回するよりも嵩張らず、運搬及び輸送、保管するときのスペースが小さくて済み、取扱い及び管理が容易に行える。
【００５３】

As described above, the accommodating portion Ca, which is formed by forming the accommodating portion Ca having a concave shape at a predetermined interval with respect to the entire length of the plastic sheet A in a substantially spiral direction, and the accommodating portion wound in advance. Since the Ca and the subsequently wound accommodation portion Ca are fitted to each other, the accommodation portion Ca is not deformed, crushed, or wrinkled, and the stress applied to the accommodation portion Ca is dispersed. Therefore, the shape at the time of molding can be maintained, and the commercial value of the molded product C is not impaired, and the operation of accommodating the storage object E can be reliably performed. In addition, it is less bulky than spirally wound, requires less space for transportation, transportation, and storage, and can be easily handled and managed.
[0053]
In addition, since the accommodating portions Ca are wound while being held in the form at the time of molding, the operation of unwinding and unwinding the continuous molded product B wound in a substantially spiral shape can be easily performed. The operation of supplying B and the operation of accommodating the storage object E can be mechanically performed, so that labor can be saved and the efficiency can be improved. In addition, since there is no human intervention, the packaging and storage of the molded article C can be performed hygienically.

FIG. 10 shows another example of the molded article C formed in the continuous molded article B, in which the object E is accommodated in a concave accommodation section Ca formed in the molded article C, and the rear side of the molded article C is shown. Along a bent portion Cc formed by bending a sealing sheet D formed to a size substantially corresponding to the above to the peripheral edge of the molded product C (for example, both edges, three edges except one edge, four edges). Since the slide is inserted and sealed, the same operations and effects as those of the above embodiment can be obtained.
[0055]
FIG. 11 shows another example of the molded product C formed on the continuous molded product B, and the object E is formed on one or both of the front surface portion Cd and the rear surface portion Ce constituting the molded product C. The front part Cd and the rear part Ce, which are housed in the recessed housing part Ca and formed integrally, are bent in opposing directions along the folding ruled line Cf formed at the mutually bent part, and the front part Cd and the rear part are folded. Since the opposing surface or the opposing edge of the surface portion Ce is bonded and fixed with an adhesive and sealed, the same operation and effect as those of the above-described embodiment can be obtained. Further, the molded product C and the sealing sheet D can be sealed, for example, by fitting a concave portion and a convex portion to each other, or by fixing with a stopper.
[0056]
