【発明の属する技術分野】
本発明は、例えばオーディオのスピーカーなどの被包装物を収納する段ボール板製の包装箱に関するものである。
【0002】
【従来の技術】
従来から特に大型の被包装物を収納する段ボール板製の包装箱を最終的に廃棄処分する場合、手で破るなどして小さく切り刻み、合成樹脂製のごみ袋に入れるなどして棄てるか、あるいは無理やり小さくなるように折り畳み、封緘テープや紐で折り畳み状態を保持して棄てているのが現状である。しかしながら、段ボール板を手で破って小さく切り刻むのは力を要し、非常に手間であり、また段ボール板製の包装箱を無理やり小さくなるように折り畳む場合、折曲線のない部分で折り畳まなければならず、この場合も力を要し、さらにこの折り畳み状態を保持しつつ封緘テープや紐を巻き付けるのに手間が掛かり、廃棄処分が煩わしいという問題があった。
【0003】
そこでこのような問題を解決すべく平面的に折り畳みでき、廃棄処分に便利な包装箱として、特許文献1に開示されているものが知られている。
しかしながら、上記特許文献1に開示されている包装箱は、フラップの折曲線に沿ってミシン目状カット線が形成されており、ミシン目状カット線を切り開くことにより平面的に折り畳むことができるが、1枚の板部の途中の折曲線のない部分で折り畳む場合は上記した廃棄処分の仕方と同様に力を要し、1枚の板部の途中でコンパクトに折り畳むのに上記した廃棄処分の仕方と同様の手間が掛かるという問題があった。

【発明が解決しようとする課題】
本発明はこのような課題を解決するもので、包装箱の廃棄処分時の折り畳みを容易に行なえるようにすることを目的とするものである。
【0006】
【課題を解決するための手段】
この課題を解決するために本発明の包装箱は、段ボール板を材料として作られ、長辺側の対向側板と短辺側の対向側板とからなる2組の対向側板と、それぞれの対向側板の下端に連設された底板形成用フラップと、それぞれの対向側板の上端に連設された上蓋形成用フラップとを備えてなり、長辺側の対向側板およびこの対向側板の下端に連設された底板形成用フラップとこの対向側板の上端に連設された上蓋形成用フラップにはこの対向側板の幅方向の中央部で1本の連続する折り曲げ線を形成してなり、短辺側の対向側板の内、少なくとも一方の側板の下端に連設された底板形成用フラップおよび少なくとも一方の側板の上端に連設された上蓋形成用フラップにはこの側板との連設線とほぼ平行に折り曲げ線を形成してなる平面形状が長方形の包装箱であって、廃棄処分時に短辺側の対向側板の内、他方の側板の下端に連設された底板形成用フラップとこの側板の上端に連設された上蓋形成用フラップをそれらを連設する側板に重なるように折り曲げ、長辺側の対向側板の下端に連設された底板形成用フラップとこの側板の上端に連設された上蓋形成用フラップをそれらを連設する側板に重なるように折り曲げ、この長辺側の対向側板およびこれに連設される底板形成用フラップと上蓋形成用フラップを折り曲げ線で内側にV状に折り曲げた状態で、短辺側の対向側板の内、一方の側板の下端に連設された底板形成用フラップとこの側板の上端に連設された上蓋形成用フラップの折り曲げ線よりも先端側の差し込み片を短辺側の対向側板の内、他方の側板の内側に差し込むようにしたことを要旨とするものである。
【0007】
この構成により、他の組の対向側板の内、一方の側板の下端に連設された底板形成用フラップとこの側板の上端に連設された上蓋形成用フラップ以外のフラップをそれらが連設される側板に重ね合わせる。このとき、少なくとも他の組の対向側板の内、他方の側板の下端に連設された底板形成用フラップとこの側板の上端に連設された上蓋形成用フラップは他方の側板の内面に重なるように折り畳んでおき、かかる状態で前記1組の対向側板とこれに繋がる底板形成用フラップおよび上蓋形成用フラップを折り曲げ線で内側にV状に折り曲げて、前記差し込み片を他の組の対向側板の内、他方の側板の内側に差し込むことにより、包装箱を廃棄のためにコンパクトに小さく折り畳んだ状態を保持させることができる。
