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を備えた合成樹脂製の折り畳み箱であって、
底片の側縁のうち底片連結ヒンジ部と連結した側縁と直角な角度を介して隣接する側縁に係止部を設けると共に、箱状に組み立てた状態で底片連結ヒンジ部を介して底片を連結した側板と直角な角度を介して隣接する側板の内面下端部に浮き上がり防止突起を設け、箱状に組み立てた状態で上記係止部が浮き上がり防止突起を乗り越えて浮き上がり防止突起の下面側に係止し、
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において両側に隣接する2側板のうち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部を設け、
上記重なり代吸収部の側端面と隣接する側板の側端面との間に、重なり代吸収部に対して隣接する側板を折り畳んだ際に重なり代吸収部の側端面と隣接する側板の側端面とが互いに干渉するのを避けるための小間隙を介して重なり代吸収部の外面側と隣接する側板の外面側とを側板連結ヒンジ部で連結し、底片の側縁のうち底片連結ヒンジ部と連結した側縁と直角な角度を介して隣接する側縁に係止突起を設け、箱状に組み立てて側板に対して底片を直角姿勢とした状態で、係止突起を上記小間隙に着脱自在に係止して成ることを特徴とする合成樹脂製の折り畳み箱。
