BOX-SHAPED CONTAINER

PROBLEM TO BE SOLVED: To provide a box-shaped container that can be improved in strength and visibility compared with conventional ones.SOLUTION: In a box-shaped container 10, a plurality of laterally long members 24 and longitudinally long members 25 constituting side walls 20 and 30 with a lattice structure have cross sections with a groove-shape structure and therefore have higher strength, so that balance in strength of the side walls 20 and 30 as a whole is improved, resulting in improvement in strength of the side walls 20 and 30 as a whole. Furthermore, groove bottom walls 24B of the laterally long members 24 and groove bottom walls 25B of the longitudinally long members 25 are arranged separately on inner surfaces and outer surfaces of the side walls 20 and 30 respectively, so that balance in a thickness of the side walls 20 and 30 can be improved as well, which for instance can suppress warpage of the side walls 20 and 30. Further, since the strength of the side walls 20 and 30 as a whole is improved, meshes of lattices of the side walls 20 and 30 can be expanded so that visibility and ventilation can be improved.SELECTED DRAWING: Figure 1 【課題】強度及び視認性を従来より高くすることが可能な箱形容器を提供する。【解決手段】本発明の箱形容器１０では、格子構造の側壁２０，３０を構成する複数の横長部材２４及び縦長部材２５のそのものが断面溝形構造をなして強度が高くなっているので、側壁２０，３０の全体の強度のバランスが向上し、その結果、側壁２０，３０の全体の強度が向上する。しかも、横長部材２４の溝底壁２４Ｂと縦長部材２５の溝底壁２５Ｂとを、側壁２０，３０の内面と外面とに分けて配置したので、側壁２０，３０の厚さ方向でもバランスが向上し、例えば、側壁２０，３０の反りを抑えることもできる。また、側壁２０，３０の全体の強度が向上するので側壁２０，３０の格子の目を大きくして、視認性及び通気性を向上させることもできる。【選択図】図１
