PROBLEM TO BE SOLVED: To improve the stability of a stack of unfolded setup containers, by forming projections on the under side of a bottom plate and by covering the end faces of the projections with a rubber or a synthetic resin, in the one in which side plates are connected to the four sides of a flat square bottom plate so as to be freely erectile and which is set up into a box when used. SOLUTION: In a setup container A made of a synthetic resin, side plates 3 are connected to the four sides of a square bottom plate 1 via hinges 2 so as to be freely erectile, engagement parts 4 which engage when the container is set up is formed at both ends of each side plate 3, and it is set up into a box by engaging the engagement parts 4 and it is unfolded flat by releasing the engagement of the engagement parts 4. In the case, a plurality of projections 5 are formed on the under side of the bottom plate 1, and recesses 6 into which projections 5 fit are formed on the upper side of the bottom plate 1. When the setup containers A are stacked in the state of being unfolded, the projections 5 are fitted into the recesses 6 made in the upper side of the bottom plate 1 of the setup container A which is underneath it, thus, lateral slippage is prevented as much as possible, and collapse before binding with a binding device is prevented. |
