Reusable assembled box and method of transport thereof

A method of transport of a reusable assembled box, said reusable assembled box comprising:

• a first member in a substantially rectangular shape forming a base and a pair of opposing side walls folded up from said base;
• a second member in a substantially rectangular shape provided with a base, overlain on the base of said first member, in a shape substantially identical to that of said first member and forming a pair of side walls adjacent to the side walls of said first member;
• and
• coupling members for detachably coupling upper end corners of adjacent side walls of said first and second members assembled into a box by overlaying the bases each other;
• wherein, after said reusable assembled box is transported as a transport box, said coupling member is removed from said assembled box to have said first and second members disassembled for extension, and said extended first and second members are respectively piled up for sending back.

A method of transport of a reusable assembled box, the reusable assembled box comprising:

• a first member in a substantially rectangular shape forming a substantially square base and a pair of opposing side walls folded up from said base;
• a second member in a substantially rectangular shape provided with a base, overlain on the base of said first member, in a shape substantially identical to that of said first member and forming a pair of side walls adjacent to the side walls of said first member;
• and
• coupling members for detachably coupling upper end corners of adjacent side walls of said first and second members assembled into a box by overlaying the bases each other;
• wherein, after said reusable assembled box is transported as a transport box, said coupling member is removed from said reusable assembled box to have said first and second members disassembled for extension, and said extended first and second members of substantially identical shape are piled up in the same direction for sending back.
