PURPOSE: To reduce wrapping cost without need for a separate synthetic resin handle member

CONSTITUTION: This is a cubic package box 1 made of a cardboard, wherein an approximate U-shaped cut 5 is provided so that it is connected to an upper lid forming flap 2 of the box 1 via a fold line 8 in parallel with a fold line 7 between it and a side plate 6 connected to the upper lid forming flap 2 to form a handle piece 4. The handle piece 4 is designed to form a plate part 10 which is bent approximately perpendicularly to the upper lid forming flap 2 when fingers are put into the cut 5 to grasp and a plate part 12 which is connected to the plate part 10 via a fold line 11 and also bent sharply with respect to the plate part 10, so that fingers can be hooked on a handle part formed on the upper lid forming flap to allow the box 1 to be carried.
