Description

【０００１】
【発明の属する技術分野】
本発明は、包装体に関するものであり、より詳しくは容器片と蓋片とが折畳まれることにより収納部が形成され、文具、化粧品、電池、日用品、ビデオテープ、食品等の種々の被包装物を包装して収納するためのプラスチックシートからなる包装体に関するものである。
【０００２】
【従来の技術】
従来より、この種の包装体としては、種々のものが提案されており、例えば図１５に示すような包装体が公知である。
該包装体は、商品を保持可能な突設部12' が表面側より突出して成形された容器片10' と、該突設部12' の嵌入可能な凹部32' が裏面側より突出して成形された蓋片30' とが、折曲線14' を介して連設されてなり、折曲線14' に沿って両片10',30' を折畳むことで突設部12' と凹部32' とにより商品Ａ' が収納される収納部Ｂ' が構成されるものであった。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記包装体にあっては熱成形された突設部12' が薄いので、該突設部12' の腰が弱くなり、蓋片30' を開放して商品Ａ' を取り出す際に該突設部12' が捩じれたり、変形したりすることにより、商品Ａ' が落下、離脱する等の問題を有していた。
【０００４】
また、容器片10' には突設部12' が存在するので平面部が少なく、ラベルを貼着したり、表示等を印刷することができず、説明文や注意書きの多い商品の包装用については使用できないという問題を有していた。
【０００５】
そこで、本発明はこのような問題を解決すべくなされたものであり、十分な強度を有し、且つ説明文や注意書き等を添付或いは印刷等が行い易い包装体を提供することを課題とする。
【０００６】
【課題を解決するための手段】
本発明は上記課題を解決すべくなされたものであり、本発明に係る包装体は、プラスチック製のシートからなり、容器片10と蓋片30とが折畳まれることにより商品等の被包装物Ａを収納するための収納部Ｂが形成される包装体であって、前記容器片10又は／及び蓋片30は、折曲線14,34 を介して補強片50と連設されてなることを特徴とする。
【０００７】
本発明に係る包装体は上記構成からなるので、折曲線14,34 に沿って容器片10、蓋片30、補強片50を折り畳むことにより、商品等の被包装物Ａを収納用成形部Ｂに収納して包装することができ、包装後は補強片50により少なくとも一片10側は二重構造となるので、該片10の強度を維持することができ、しかも補強片50との間に取扱説明書等の添付シートをも介在させることもできる。また、容器片10及び蓋片30に突設部等を成形した場合にあっても、補強片50への印刷、貼着等により、説明文や注意書き等が容易に表示し得る。
【０００８】
また、本発明に係る包装体は、蓋片30が折曲線34を介して容器片10と連設され且つ容器片10が他の折曲線14を介して補強片50と連設されてなる構成を採用することも可能であるが、該構成からなる包装体は、各片10, …を折り畳むだけでなく別途補強片50を容器片10に接着することが必須となるので、請求項２記載の如く、蓋片30が折曲線34を介して補強片50と連設され、且つ補強片50が他の折曲線14を介して容器片10と連設されてなる構成を採用することが好ましい。
かかる構成からなる請求項２記載の包装体にあっては、容器片10と蓋片30とを折曲線14,34 に沿って補強片50側に折畳むことにより、被包装物Ａを収納用成形部Ｂに収納して包装されることとなる。
【０００９】
また、請求項２記載の包装体は、請求項３記載の如く容器片10に被包装物Ａを収容できるように突設部12を形成し、蓋片30に折畳まれた際に突設部12を覆う凹部32を設けた構成を採用することもできる。
該構成からなる包装体は、補強片50側に容器片10を折曲線14に沿って折畳み、容器片10の突設部12に被包装物Ａを収容せしめた後、蓋片30を折曲線34に沿って折畳むことで、蓋片30の凹部32が容器片10の突設部12を覆い、突設部12と凹部32とにより構成される収納部Ｂに被包装物Ａを包装することができる。
【００１０】
かかる請求項３記載の包装体にあっては、請求項４記載の如く補強片50に突設部12に嵌入可能な嵌入部52を設けることもでき、該構成を採用することにより、容器片10を補強片50の表面側に折曲線14に沿って折畳んだ際に、補強片50の嵌入部52が突設部12に嵌入され、突設部12の強度を高めることができる。また、嵌入部52の嵌入により、容器片10と補強片50とが一体となるので、蓋片30の開閉等の際に不用意に容器片10が補強片50に対して起き上がる等を防止できる。
【００１１】
さらに、請求項３記載の包装体にあっては、請求項５記載の如く容器片10に外側に突出した係合部16を形成し、蓋片30と補強片50との折曲線34に該係合部16を挿入可能な被係合部56を形成した構成を採用することもできる。該構成を採用することにより、容器片10を補強片50側に折畳み、係合部16を折曲線34の被係合部56に挿入することにより、容器片10と補強片50とを容易に一体化することができ、蓋片30の開閉等の際の作業性が容易となる。
【００１２】
また請求項２記載の包装体は、請求項６記載の如く補強片50が折曲線14,34 を介して容器片10又は／及び蓋片30に隣設された補強片本体60と、立ち上がり用の折曲線54を介して補強片本体50に隣設された立ち上がり部70とを具備し、容器片10又は／及び蓋片30には、折畳まれることにより他片30,10 側に当接し、内壁面19,39 より収納部Ｂを構成する突設部18,38 が形成された構成も採用し得る。
該構成を採用することにより、補強片本体60に隣設した片10,30 を該補強片本体60側に折曲線14,34 に沿って折畳み、突設部18,38 に被包装物Ａを収容せしめた後、容器片10と蓋片30とを折畳むことで、突設部18,38 により構成される収納部Ｂに被包装物Ａを包装できる。
尚、この請求項６記載の包装体にあっては、補強片50が折曲線14,34 を介して容器片10及び蓋片30に夫々隣設した一対の補強片本体60,60 と、この一対の補強片本体60,60 の間に立ち上がり用の折曲線54を介して設けられた立ち上がり部70とを具備せしめる構成を採用することが好ましい。これにより、容器片10及び蓋片30の強度を維持できるとともに、一方の補強片本体60から他方の補強片本体60にかけて一枚の説明書、商品表示用のシート等を保持せしめることができ、特に補強片50を透明・半透明にすることにより、商品表示を一枚のシートによって行うことができる。
【００１３】
また請求項６記載の包装体にあっては、請求項７記載の如く補強片50に突設部18,38 に嵌入可能な嵌入部68を形成することもでき、該構成を採用することで突設部18,38 の形成された片10,30 を補強片本体60側に折畳んだ際に嵌入部52が突設部18,38 に嵌入し突設部12の強度を高めることができ、しかも該片10,30 が不用意に補強片本体60から起き上がることを防止できる。
【００１４】
さらに請求項６記載の包装体にあっては、請求項８記載の如く容器片10又は／及び蓋片30に係合部16,36 を形成して、立ち上がり部70の折曲線54に該係合部16,36 を挿入可能な被係合部56を形成した構成を採用することもできる。該構成からなる包装体は、係合片16,36 が形成された片10,30 を補強片本体60側に折畳んだ際に係合部16,36 を被係合部56に挿入することで、該片10,30 と補強片50とを容易に一体化でき、他片30,10 の開閉等の際の作業性が容易となる。
【００１５】
【発明の実施の形態】
＜第一実施形態＞
以下本発明の実施の形態について説明するが、まず図１に示す如く容器片10と、該容器片10に折曲線14を介して連設された補強片50と、該補強片50に他の折曲線34を介して連設された蓋片30とからなるプラスチックシート1 により構成される包装体ついて説明する。
尚、ここでプラチックシート1 として厚み0.3mm のポリ塩化ビニルからなり硬質で熱成形可能な透明な単層からなるシートを用いているが、その他ポリプロピレン、ポリエチレンテレフタレート、ポリスチレン等からなり、硬質又は半硬質で透明又は半透明な単層及び複層からなる厚み0.1 乃至2.0mm 程度のシート等も使用し得る。また、折曲線14,34 としてミシン目を採用しているが、その他凹溝等の折目等も採用することも可能である。
前記プラスチックシート1 は平面視長方形状で、一枚の長さ方向に三等分した位置に互いに平行な折曲線14,34 が刻設され、これにより容器片10、補強片50、蓋片30が何れも略同一の形状をなして区分されている。
【００１６】
前記容器片10には、その周縁に耳部11を残し中央部が裏面側に突出成形され突設部12が形成されている。該突設部12には内部に商品Ａが収容できるように複数の収容凹部13が形成されている。ここで、収容凹部13の形状は包装すべき商品Ａと略同一形状をなしている。なお、収容凹部13の形状は商品Ａを複数まとめた形状（例えば二つの商品を重ねた形状）等にすることもできる。
また、前記蓋片30には、その周辺に耳部31を残して中央部が裏面側に突出成形され、折曲線14,34 に沿って容器片10及び蓋片30とを補強片50側に折畳んだ際に突設部12を覆う凹部32が形成されている。ここで凹部32は、蓋片30を閉じた際に突設部12に嵌着すべく構成されている。
このような突設部12、凹部31は、プラチックシート1 を真空成形や圧空成形することにより成形できるものである。
【００１７】
さらに、容器片10には、補強片50との折曲線14と対向した辺15の略中央部より外側に突出した係合部16が突設されてなる。
また、補強片50と蓋片30との折曲線34は、その中央部が切欠かれ、折曲線14に沿って容器片10を補強片50側に折畳んだ際に係合部16が挿入可能な被係合部56が形成されてなる。
【００１８】
なお図１において、33は、包装された後に蓋片30の開閉を容易に行うための把手である。
【００１９】
上記構成からなる包装体は、まず図２（イ）に示すように補強片50の表面に商品の取扱説明書等の添付シート3 を載置して、図２（ロ）に示すように容器片10を折曲線14に沿って補強片50の表面側に折畳み、商品Ａを収容凹部13に収容する。この容器片10の折畳みに際して、係合部16を被係合部56に挿入せしめる。
そして、図２（ハ）に示すように蓋片30を折曲線34に沿って補強片50の表面側に折畳み、突設部12に凹部32を嵌着せしめることで、商品Ａを包装する。
【００２０】
上述の如き包装体にあっては、容器片10の側方より突出した蓋片30の把手33を摘んで、容易に蓋片30を開閉して使用することができる。
【００２１】
また、突設部12に凹部32が嵌着しているので、搬送中等において蓋片30が不用意に開放されることを防止できる。なお、容器片10と蓋片30の耳部11,31 に互いに嵌着可能な嵌合部を設けておくことによっても、蓋片30の不用意な開放を防止でき、商品販売前の輸送中においては蓋片30と容器片10とを粘着テープ、接着剤等の手段により密閉しておくことが好ましい。
【００２２】
さらに、購入された後にも容器として用いられ蓋片30が頻繁に開閉される場合にあっても、係合部16が被係合部56に挿入され容器片10と補強片50とが一体となっているので、蓋片30の開閉等の際に不用意に容器片10が補強片50に対して起き上がることがない。
なお、容器片10と補強片50とを一体化するにあっては、前記係合部16と被係合部56との係合のみならず、容器片10の耳部11と補強片50とを接着剤等により接着することも可能である。また容器片10を折曲線14に沿って補強片50の表面側に折畳んだ後に該容器片10と補強片50との折曲線14を加熱・冷却することにより、折曲線14を固定して、容器片10の不用意な立ち上がりを防止することもできる。
【００２３】
また、補強片50の全面が平坦に構成されているので、添付シート3 を容器片10と補強片50との間に介在させるのみならず、該補強片50に注意書き等を印刷等することもできる。尚、該印刷は、プラチックシート1 を真空成形等して突設部12等を形成する以前に行ってもよい。
さらに、補強片50が平坦ゆえに包装体の裏面が平坦となるので手でしっかり持つことができ、上記構成の包装体を弁当容器として用いるならば手でしっかり持って食べることができるという利点をも有する。
【００２４】
第一実施形態の包装体は、上記構成からなり上述の利点を有するものであったが、図４に示す如く、補強片50に容器片10を折畳んだ際に突設部12に嵌入する嵌入部52を表面側より突設することもできる。
該構成からなる包装体は、嵌入部52の内側に添付シート3 を載置して、容器片10を折曲線14に沿って補強片50の表面側に折畳んだ際に嵌入部52が突設部12の内面側に嵌入され、商品Ａを収容凹部13に収容した後に蓋片30を補強片50側に折畳み、図４（ハ）に示すように商品Ａが包装されることとなる。
このように、嵌入部52を突設することにより折畳まれた容器片10と補強片50とが一体となり、容器片10の不用意な起き上がり等を防止できるともに、突設部12の強度をも維持することができる。
なお、図４において該嵌入部52は、突設部12の約半分の高さだけ突設されてなるが、突設部12と略同様の高さだけ突設されてなるものであっても良く、さらに該嵌入部52は突設部12の強度が必要な一辺（例えば下辺52a)のみに対応して設けることも可能である。但し、容器片10の起き上がりを確実に防止するためには、少なくとも容器片10と補強片50との折曲線14に対して略平行な部分（例えば側辺52b)に嵌入部52を設けることが好ましい。
また、上記の如く嵌入部52を形成した場合、図１乃至図３に示す如く全面が平坦な補強片50に比して平坦な面は減少するものの、従来の包装体に於ける容器片10に比して印刷する面積が広い等の利点を有する。
【００２５】
さらに、上記の如く嵌入部52を形成した場合にあっては、図４（ニ）に示すように該嵌入部52には凸部57を外側に向けて突設せしめ、容器片10の突設部12には容器片10を折り畳んだ際に該凸部57よりも下方に位置し該凸部57に当接する凸部17を内側に向けて突設せしめることも可能である。このように、嵌入部52及び突設部12に互いに係止可能な係止部17,57 を形成することにより、容器片10の不用意な起き上がり等をより確実に防止することができる。なお、嵌入部52及び突設部12に互いに係止可能な係止部17,57 としては、互いに当接する凸部17,57 に限られず、両者が嵌合するものであっても良く、要は容器片10の上方への移動を阻止すべく互いに係止されるものであれば良い。
しかも、このように突設部12に係止部17を突設した場合には、図４（ニ）に示すように蓋片30にも該容器片10の係止部17と係合可能な被係止部37を形成することが好ましく、これにより蓋片30の開放も防止しうる。
【００２６】
また、第一実施形態においては、一対の折曲線14,34 が平行で、補強片50の対向する辺から夫々容器片10と蓋片30とが連設されたものについて説明したが、図５に示す如く平面視略方形状の補強片50の隣り合う辺から夫々容器片10及び蓋片30が連設されてなるものであっても良い。
【００２７】
＜第二実施形態＞
次に、本発明の他の実施形態として、図６に示す如く、容器片10と蓋片30と補強片50とからなる透明なプラチックシート1 からなる包装体であって、補強片50が一対の補強片本体60,60 と、この一対の補強片本体60,60 の間の立ち上がり部70とからなるものを例にとり説明する。
前記容器辺10及び蓋片30は、プラチックシート1 の端部より一定間隔の位置に夫々折曲線14,34 が互いに平行に刻設されて、平面視長方形状に形成されている。また、補強片50には、該折曲線14,34 とプラチックシート1 の端部との間隔と該折曲線14,34 から同一の間隔の位置に該折曲線14,34 と平行に、一対の折曲線54,54 が刻設されている。これにより、補強片50は、容器片10及び蓋片30と略同一形状の補強片本体60,60 と、該補強片本体60,60 間の立ち上がり部70とに区分されてなる。
【００２８】
さらに、前記容器片10及び蓋片30には、その周辺に耳部11,31 を残して中央部が裏面側に突出成形されて突設部18,38 が形成されてなる。ここで、該突設部18,38 は、容器片10と蓋片30とが折畳まれた際に、突設面18a,38a が互いに当接して、内壁面19,39 より収納部Ｂを構成するよう設けられている。尚、各突設部18,38 は、補強片50の折曲線54,54 の間隔（立ち上がり部70の幅）の半分で突出している。
【００２９】
また、容器片10及び蓋片30には補強片50との折曲線14,34 に対向した辺15,35 の略中央部より外側に突出した係合部16,36 が突設されている。
さらに、補強片50の立ち上がり用の折曲線54,54 は、その中央部が切欠かれ、各片10,30 を補強片本体60側に折畳んだ際に係合部16,36 が挿入可能な被係合部56,56 が夫々形成されている。
【００３０】
上記構成からなるプラチックシート1 は、まず図７（イ）に示すように一方の補強片本体60から他方の補強片本体60にかけて一枚の商品表示用の添付シート3 を載置して、図７（ロ）に示すように容器片10及び蓋片30を折曲線14,34 に沿って補強片本体60の表面側に折畳み、商品Ａを蓋片30の突設部38の内壁面39内（又は容器片10の突設部18の内壁面19内）に収容する。この容器片10及び蓋片30の折畳みに際して、係合部16,36 を被係合部56,56 に夫々挿入せしめる。
そして、図７（ハ）に示すように立ち上がり部70を折曲線54に沿って立ち上げて、さらに折曲線54に沿って容器片10を折畳んで、突設部18,38 同士を当接せしめて、商品Ａを包装する。
【００３１】
上記構成からなる第二実施形態の包装体は、容器片10及び蓋片30は補強片本体60,60 と一体となっているので両片10,30 の強度を維持できるとともに、一方の補強片本体60から他方の補強片本体60にかけて一枚の商品表示用のシート3 を保持せしめることができ、補強片50は透明ゆえに商品表示を一枚のシート3 によって行うことができる。従って、ビデオテープ等のケースに最適である。
【００３２】
また、係合部16,36 を形成したことにより上記第一実施形態と同様の利点を有するものの、上記の如く一方の補強片本体60から他方の補強片本体60にかけて一枚の商品表示用のシート3 を保持せしめる際には該シート3 にも該係合部16,36 に対応した箇所に孔部を形成することを要するので、かかる場合にあっては係合部16,36 及び被係合部56を形成しない方が好ましい（図９参照）。
【００３３】
さらに、第二実施形態においては、各突設部18,38 が立ち上がり部70の幅の半分で突出しているものについて説明したが、図９又は図１０に示すように容器片10又は蓋片30の何れか一方のみから突設部38を突設せしめ、該突設部38の突設面38a が他方の片30,10 に当接するよう構成することも可能である。
但し、容器片10及び蓋片30の何れもから突設部18,38 から突設せしめることにより、突設部18,38 の高さを被包装物Ａの高さよりも低くすることができるので、被包装物Ａの取出しが容易となる利点を有する。
しかも、該突設部18,38 を容器片10及び蓋片30の何れもから突設させる場合においても、単に突設面18a,38a が当接するのみのものに限られず、図１１に示す如く互いに嵌合すべく突設面18a,38a が形成することもできる。
【００３４】
さらに、第二実施形態においては補強片本体60を容器片10及び蓋片30とに隣設して一対設けたものについて説明したが、例えば図１０に示す如く容器片10又は蓋片30の何れか一方のみに隣設して補強片本体60を設けることもできる。
【００３５】
また、第二実施形態においては、容器片10及び蓋片30と補強片50との折曲線14,34 が何れも補強片50の折曲線54に平行であるものについて説明したが、図１１に示す如く垂直に形成されてなるものであっても良く、要は容器片10又は蓋片30が補強片本体60側に折畳むことができるように折曲線14,34 が形成されているものであれば良い。
【００３６】
さらに、第二実施形態の如き包装体にあっても、図１１に示すように補強片本体60に容器片10及び蓋片30を折畳んだ際に突設部18,38 に嵌入する嵌入部68を表面側より突設することもでき、これにより折畳まれた容器片10等と補強片50とが一体となり、容器片10の不用意な起き上がり等を防止でき、突設部12の強度をも維持することができる。但し、一方の補強片本体60から他方の補強片本体60にかけて一枚の商品表示用のシート3 を保持せしめて商品表示を一枚のシート3 によって行う場合にあっては、補強片50の全面を平坦としておくことが好ましい。
なお、上記の如く補強片本体60に突設部18,38 に嵌入する嵌入部68を設けた場合にあっては、第一実施形態と同様に嵌入部68及び突設部18,38 に図４（ニ）に示す如く互いに係止可能な係止部17,57 を設けることが好ましい。
【００３７】
＜第三実施形態＞
次に、本発明の他の実施形態として、図１２（イ）に示す如く、容器片10と蓋片30と補強片50とからなる透明なプラチックシート1 からなる包装体であって、蓋片30が折曲線24を介して容器片10と連設され、容器片10が折曲線14を介して補強片50と連設されてなるものを例にとり説明する。
プラスチックシート1 は、三等分した位置に互いに平行な折曲線24,14 が刻設され、蓋片30、容器片10、補強片50が略同一の形状をなして区分されている。
また、第三実施形態の包装体も第一実施形態と同様に、容器片10には収容凹部13が形成された突設部12が表面側に突出して成形されており、蓋片30には該突設部12を覆う凹部32が裏面側に突出して成形されている。
【００３８】
上記構成からなる包装体は、補強片50を折曲線14に沿って容器片10の裏面側に折畳み、該容器片10と補強片50との間に添付シート3 を収容せしめる。そして、商品Ａを収容凹部13に収容して蓋片30を折曲線24に沿って折畳んで突設部12に凹部32を嵌着せしめて、図１２（ハ）に示すように商品Ａを包装する。
【００３９】
上記構成からなる第三実施形態の包装体は、第一実施形態と同様に突設部12に凹部32が嵌着し搬送中等における蓋片30の不用意な開放を防止でき、補強片50が平坦ゆえに該補強片50に印刷等することもできる等の利点を有する。
但し、第三実施形態の包装体は第一実施形態と異なり、商品販売前の輸送中において補強片50を容器片10に粘着テープ等により接着することが必須となる。
【００４０】
＜第四実施形態＞
次に、本発明の他の実施形態として、図１３に示す如く、容器片10、蓋片30、補強片50を具備する透明なプラチックシート1 からなる包装体であって、蓋片30が折曲線24を介して立ち上がり片20と連設され、立ち上がり片20が他の折曲線24を介して容器片10と連設され、容器片10が折曲線14を介して補強片50と連設されてなり、補強片50が一対の補強片本体60,60 と、この一対の補強片本体60,60 の間の立ち上がり部70とからなるものを例にとり説明する。
【００４１】
前記容器片10と補強片50との折曲線14はシート1 の略中央部に刻設されている。さらに、シート1 の一端部及び前記補強片50の折曲線14より夫々一定間隔の位置に折曲線24,24 が互いに平行に刻設され、前記容器片10及び蓋片30は平面視長方形状に形成されている。この一対の折曲線24,24 の間が立ち上がり片20として構成される。
【００４２】
また、補強片50には、容器片10と補強片50との折曲線14から、該折曲線14と立ち上がり片20の折曲線24,24 との間隔と同一間隔で折曲線54,54 が夫々互いに平行に刻設されてなる。これにより補強片50は、容器片10と略同一形状の容器片用の補強片本体60と、この容器片用の補強片本体60に隣設した立ち上がり部70と、該立ち上がり部70に隣設し蓋片30と略同一形状の蓋片用の補強片本体60とに区分されてなる。
前記容器片10及び蓋片30には、第二実施形態と同様の突設部18,38 が形成されている。
【００４３】
上記構成からなるプラチックシート1 は、まず図１４（イ）に示すように一方の補強片本体60から他方の補強片本体60にかけて一枚の商品表示用の添付シート3 を載置し、図１４（ロ）に示すように容器片10、立ち上がり片20、蓋片30を折曲線14に沿って補強片50側に折り畳み、商品Ａを蓋片30の突設部38の内壁面39内（又は容器片10の突設部18の内壁面19内）に収容する。
