- 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、側板の上端縁に蓋片連結ヒンジ部を介して折り畳み自在に連出した蓋片とで構成された合成樹脂製の折り畳み箱において、
上記略平行四辺形状に折り畳んだ際に鋭角となるように折り畳まれる方の一対の対角部の隅部の両側の2つの側板のうちの一方の側板の端部に4枚の側板が偏平に折り畳まれ且つ各底片が各側板の内面に重なった折り畳み状態で上記重なり厚みに対応する重なり代吸収用突部を上下方向の全長にわたって突設し、
上記略平行四辺形状に折り畳んだ際に鈍角となるように折り畳まれる方の一対の対角部の隅部の両側の2つの側板のうち一方の側板の側端面部の上下方向の一部に凸又は凹の嵌め込み部を、他方の側板の側端面部の上下方向の一部に凹または凸の被嵌め込み部を形成し、箱状に組み立てた状態で嵌め込み部と被嵌め込み部とが凹凸嵌合して隣接する側板のなすコーナ部分を構成し、
上記重なり代吸収用突部を備えた一方の側板と、隣接する他方の側板を折り畳み自在に連結するに当り、硬質合成樹脂よりなる一方の側板の端部の内面側に硬質合成樹脂よりなる重なり代吸収用突部を一体に突設すると共に、硬質合成樹脂よりなる隣接する他方の側板の端部に軟質合成樹脂よりなる側板連結ヒンジ部を設け且つこの側板連結ヒンジ部の先端部に硬質合成樹脂よりなる接続部を設け、硬質合成樹脂よりなる上記重なり代吸収用突部に、硬質合成樹脂よりなる接続部を重複一体化して成ることを特徴とする合成樹脂製の折り畳み箱。 - 上記嵌め込み部と被嵌め込み部との凹凸嵌合の上下方向に対向する嵌合界面が水平面となっていることを特徴とする請求項1記載の合成樹脂製の折り畳み箱。
