Claims (1)
- 前後左右にそれぞれ対向する4枚の側板の隣接する側端部同士を側板連結ヒンジ部で折り畳み自在に連結して箱形状に組み立てた状態で平面視長方形又は正方形状となり、且つ、折り畳みに当たって一対の対角部の隅部が鋭角となり且つ他の一対の対角部の隅部が鈍角となるように略平行四辺形状に折り畳むことを経て偏平に折り畳むことができる角筒状側壁構成部と、4枚の側板の各下辺からそれぞれ底片連結ヒンジ部を介して底片を折り畳み自在に連出すると共に、折り畳み状態で各底片が各側板の内面に重なるように折り畳まれ且つ角筒状側壁構成部を箱形状に組み立てた状態で底片同士が重なって箱形状の底を形成するようにした底板構成部と、側板の上辺から蓋片連結ヒンジ部を介して連出した蓋片とを備えた合成樹脂製の折り畳み箱であって、
側板の外周部が外面に側板連結ヒンジ部や底片連結ヒンジ部や蓋片連結ヒンジ部等のヒンジ部を重複一体化したヒンジ部重複平坦面部となると共に、該外周のヒンジ部重複平坦面部に囲まれた部分が側板強度確保部となり、上記側板強度確保部の内面側の上端から上のヒンジ部重複平坦面部の内面の上端に至る縦補強リブをヒンジ部重複平坦面部の内面部に一体に形成し、上記側板強度確保部の内面側の下端から下のヒンジ部重複平坦面部の内面の下端に至る縦補強リブをヒンジ部重複平坦面部の内面部に一体に形成し、
少なくとも上記側板強度確保部の上下左右部分は水平断面波形状をした波形断面形状部となり、少なくとも側板強度確保部の左右部分の波形断面形状部は、上部の波形断面形状部の下端から下部の波形断面形状部の上端に至るように上下に連続した連続波形断面形状部となり、上記左右の連続波形断面形状部において上下の縦補強リブを側板強度確保部の波形状の内面側に突出した部分に連続させ、波形断面形状部の外面側に突出した部分である谷部の谷底がヒンジ部重複平坦面部と略面一で、ヒンジ部重複部平坦面の内面側において、波形断面形状部の内面側の突出部分である山部の頂部をヒンジ部重複平坦面部よりも内面側に突出させ、上記上下の縦補強リブを側板強度確保部の波形状の内面側に突出した部分に連続させて成ることを特徴とする合成樹脂製の折り畳み箱。
