In which the peripheral connecting positions of the box walls are connected by the ".OMEGA." type hinges, and there are locking clips fixed in the upper and lower ends of the hinges. The peripheral edges of the box cover and box bottom are fixed by the grooved metal rim, and there are locking teeth fixed inside the box cover and box bottom. When in use, the box body is pushed off, and the upper and lower edges of the box body are inserted into the metal grooves of the box cover and box bottom which are buckled, the locking clips with the locking teeth are meshed and locked. Once the box cover and box bottom are opened, then some traces will remain on the box cover which are not recoverable. In the mean time, for transporting the empty, the box body can be closed in randomly from left or right. This packing box is convenient to use and has a good safety feature, so that it is an ideal substitute for the current packing boxes.
