In FIG. 3, the box-shaped transport item to be packed transports an electrical component 1 that incorporates a printed circuit board, a transformer, etc. The mounting pieces 3 are formed as protruding parts on both the left and right sides. In order to pack the electrical equipment 1,
The whole part is packed in a packaging body 4 made of corrugated cardboard, and in the cross-sectional view shown in FIG. At the same time, the attachment piece 3 is also pressed down by the lower surface of the angular bent portion 5. A lid 7 is formed on the upper surface of the angular bent portion 5. Next, in FIG. 2, a detailed explanation will be given using an expanded rMJ diagram of the package 4. In this developed view, first, a pair of side surfaces 9,
9a and the rectangular bent portion 5 configured in a rectangular tube shape extend in a pair symmetrically. In order to form this square bent part 5 into a square cylinder, the fold line 10, 10a including the side faces 9, 9a is
and the broken line 11. I'm putting in lla.

The square bent portion 5 is provided with a square tube locking hole 14 into which a square tube fixing piece 13 is fitted, on the side that becomes the inner top surface 12 (FIG. 1) when formed into a square tube shape.

On the other hand, in the lateral direction of the side surfaces 9, 9a, there are a pair of reinforcing pieces 15 and a fold line 16, which are formed short and bent inward for reinforcement, and on the other side, formed long and bent inward. A pair of long reinforcing pieces 17 that are bent to be reinforced and their fold lines 18 are provided. On both sides of the bottom surface 80, a lid body 7 and a locking piece 2o extending to the vertical side surface 19 and a neck portion 20a are provided, which are bent along fold lines 21, 22, and 23.
