A packing vessel 10, made of the sheet, has a three-dimensional box shape with a top opening, consisting of a bottom part 5 made of the bottom surface 5A, the front 1 and the back 3 made of the first surface and the third surface respectively, the right side gusset part 2 and the left side gusset part 4, made of the second surface 2A and the fourth surface 4A respectively. The folding of turned-back openings are easily unfolded so that the openings can be untied and extended.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
