Abstract

A folding structure for a foldable container having a base platform, bottom side rails disposed at both sides of the base platform, and corner posts disposed at both sides of the bottom rails. The corner posts are pivotally attached to the bottom side rails via pins and the sides of the corner posts are provided with corner post locking devices which can hold the corner posts in an upright position or a folded down position. The corner post locking device includes inner locking apertures arranged on both sides of the ends of the bottom side rails. Outer locking apertures are arranged on both sides of the lower ends of the corner posts which correspond to the inner locking apertures when the corner posts are in the upright position. Threaded taper pins are further provided which engage with the inner and outer locking apertures correspondingly.
