PURPOSE: To prevent the mutual sliding of a cardboard box when piled by the installation of a napped region with one or more anti-sliding factors on one of the surfaces. CONSTITUTION: For example, on the lower part of a container element 1, the napped regions 12, 13, which a cross section is partially cone type, are formed. The napped regions 12, 13 are divided into the rectangular napped regions 12, 13. The napped regions 12, 13 are disposed according to separate lines 14a, 14b, and the lines 14a, 14b are alternatively disposed with each other in the interval of the napped regions 12, 13. And, each of the napped regions 12, 13 is disposed at the corner symmetrically with the center line of a lower side 3 of the container 1. This facilitates the prevention of the mutual sliding when the cardboard boxes are piled. |
