PROBLEM TO BE SOLVED: To provide a built-up container having reduced man-hours and the numbers of parts, being facilitated in building-up and collapsing by blow molding each surface board of the contained integrally including hinges into a hollow shape having a heat-insulation and cushioning property. SOLUTION: The built-up type container is built up by setting connection means 21A for connecting each adjoining side surface boards 23, 24, 25, 26, affixing each bottom plate hinge at both distal end parts of either one of opposite side surface boards, providing generally rectangular engagement piece (b) elongated from each bottom plate and hinge, and preparing connection means 21B for rotating the connection means (b) and connecting each side surface board 23, 24, 25, 26, thus allowing the container main body 21 not to be collapsed without intention. |
