ABSTRACT:
A folding box includes a pair of opposed first side walls each foldable along a vertical direction, a pair of opposed second side walls, and a pair of bottom plates. Each bottom plates includes a central trapezoidal portion and a pair of triangular portions hingedly connected respectively to opposite sides of the trapezoidal portion. With this construction, the box made, for example, of a corrugated board can be folded into a compact size, so that the area of the folded box is small.
