Abstract
A rectangular-parallelepiped packaging box having three folding lines, in each of at least one of four corners of top and bottom faces of the box, interconnecting three ridgelines which meet at each of the four corners. At these corners are formed concaved sections by folding pointed corners inward along the folding lines. A worker, therefore, can easily insert the hands into the concaved sections and lift the box. During transport, the worker grips the box firmly with the fingers put in the concaved sections, and therefore there will not occur such a hazard that the box slips off the hands and down.
