【発明の属する技術分野】
本発明は、自動製函機での組立に対応可能なプラスチックシート製の包装容器に関する。
【０００２】
【従来の技術】
透明性が良好で剛性もあるアモルファスポリエチレンテレフタレート（Ａ―ＰＥＴ）などのプラスチックシートに折り曲げ罫線を設けてなる包装容器が造られている。被収納物はそのまま容器内に入れられるか、或いは中容器に支持させた状態で中容器ごと収納していた。
【０００３】
【発明が解決しようとする課題】
しかし、被収納物を直接入れるのでは、容器内で被収納物ががたつき、中容器を利用するのは、中容器という別部材の製造、使用が必要で、コスト高となり、収納作業その他の取り扱いも煩雑になるなど、問題点が多々あった。
本発明は、上記問題点に着眼しつつなしたものであり、資材を節約しつつ、簡潔に製造でき、被収納物を直に収納するだけで容器内に被収納物を定置でき、しかも緩衝作用も持たせて収納可能とした包装容器を提供せんとするものである。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、本発明は、正面板部、左側面板部、背面板部及び右側面板部の各板部を折り曲げ罫線を介して連設し、正面板部の側端に糊代片を折り曲げ罫線を介して連設し、背面板部の上下端に折り曲げ罫線を介して蓋片を連設し、両蓋片の先端に折り曲げ罫線を介して差込み片を連設し、左右側面板部の上下端に折り曲げ罫線を介して折込み片を連設して形成された透明乃至半透明のプラスチックシートを折り曲げて組み立てられる包装容器において、正面板部と背面板部の面内に、容器内方に突出する複数の内方突起を、両面板部の左右の折り曲げ罫線に沿って二列に且つ上下に等間隔離して設けるとともに当該二列の内方突起の下側であって左右の折り曲げ罫線の略中間の位置にも内方突起を設け、容器に収納した被収納物の外周面と底面とに、正面板部の内方突起と背面板部の内方突起が当接し、被収納物が各面板部及び蓋片から離間して宙に浮いた状態で容器内に定置し保持されるように構成されたことを特徴とする。
容器の組立て固定は、形成した糊代片と糊代片が接合する面板部端部とに、互いに嵌合して固着する中空状突起を形成しておき、これらの突起を嵌合して行うことができる。糊代片を接着剤で接着してもしなくても任意である。
【０００５】
【発明の実施の形態】
以下、本発明の一例としての実施の形態を図面によって説明する。
図１は本発明に係る包装容器の一例を示す展開図、図２はこれを組立てた包装容器を示す斜視図、図３はその断面図、図４は糊代片の嵌合構造を示す部分断面図である。
【０００６】
図１は、方形箱状の包装用ケースを形成するためのプラスチックシートであり、Ａ−ＰＥＴ、ポリプロピレン、ポリエチレン、ポリカーボネート、その他の単体又は複合体としてなるプラスチックシート材を加圧加工し、輪郭を型取り加工して形成してある。
このシートは、正面板部１、左側面板部２、背面板部３、右側面板部４を順次折り曲げ罫線５を介して連設し、正面板部１の反対側端に糊代片６を折り曲げ罫線５を介して連設し、背面板部３の上下に折り曲げ罫線５，５を介して蓋片７,８を、蓋片の各先端に折り曲げ罫線５，５を介して差込み片７ａ，８ａを連設し、左右側面板部２，４の上下にそれぞれ折り曲げ罫線５を介して折込み片９を連設してある。
【０００７】
而して、正面板部１と背面板部３の面内に、折り曲げ罫線５に沿って肉厚方向に突出した複数個の内方突起１０，１１を形成してある。この内方突起は、図２，３にも示すように、組立てた包装容器の内方に突出し、容器内に収納した被収納物１４が各面板部１，２，３，４及び蓋片７，８から離間して宙に浮いた状態で定置するように、被収納物の輪郭部分に当接するように適当な間隔をおいて形成し、図１（Ａ）に示すように正背面板部に対向状に形成するのが好ましいが、被収納物の外形に対応するように形成してある。内方突起１０，１１はまた、図１（Ｂ）に円筒形頂部を球状とした形状で示したが、任意形状とすることができる。

さらに、糊代片６とこれが接合する右側面板部４の側縁沿い部分には、図４にも示す如く、互いに嵌合可能な若干膨頭状の中空状突起１２，１３を適当な間隔をおいて複数個形成してある。この中空状突起１２，１３は、糊代片６を右側面板部４端部に合わせ、合致した両突起を押圧して嵌合し固着するように設定してある。接合した糊代面をさらに接着剤で接着するのは任意である。
上記包装容器は透明乃至半透明の容器とすることにより、被収納物が容器内中央に浮いているように定置させている視覚効果を得ることができる。内方突起１０，１１を配置していない面を或いは配置してある面を部分的に透明乃至半透明とすることもできる。
【０００９】
【発明の効果】
上記のように本発明によれば、被収納物を容器内に直に収納するだけで被収納物は内方突起によって容器内中央部に定置して保持される。被収納物が容器内に浮いているような状態の外観視覚効果が得られる。被収納物は、シートを圧空・真空成型などによって成型した内方突起によって支持され、容器面から離間状態で保持されるので、緩衝効果が得られ、被収納物の保護に効果がある。これらの効果を発揮する包装容器が、資材を節約しつつ、簡潔に製造可能である。
