The present invention is configured to fit the incision, but the first surface, second surface and the second inner and outer side integrally with the bottom surface of the packing box, the engaging surface formed on the first and second external side formed on the first and second internal side above and to enable a firm coupling without the need for adhesives, by claim 1, 2 further includes a first and second upper first and second upper surface engaging the support surface section is formed on one side of the support by the inner side to be coupled are inserted into the first surface, 2, the upper support surface engaging the handle portion surface and the second first and second upper surface is fitted to the engagement portion supporting the adhesive-free environment-friendly packing box to that firmly support the load of the object to be housed is formed in the interface both ends of the upper surface to relate.
Is environment-friendly packing box without the need for adhesives of the present invention for achieving the above object, a bottom surface, a first side which is adjacent to the bottom surface and to the first folding line as the boundary forming folded to the inside of the bottom surface and a second side, a first external side and a second inner side and jidoe made by the first inner side and a second outer side which is formed on both sides of the second surface, the first formed on both sides of the first surface and the inner side surface and the second inner side fitting cleavage plane plural form, respectively, the first inner side surface and the second the first external side and a second external side, inside the first being adjacent each to form the outside of the inner side and it characterized in that the engaging surface corresponding to the incision surface of the fitting side with a second inner side that is formed plural.
According to the present invention, because such integration of all surfaces of the packing box, without using an adhesive, and fitting to form a side of a double, it is possible to minimize the harmful effects on the environment and human body, and the accommodated goods and it enables the stable storage and transport, regardless of the weight, it is possible to prevent a phenomenon in which the handle is damaged by the load of the object to be received by further comprising a support surface for supporting the handle on the top, and the load to be concentrated on the handle and it is possible to be distributed throughout the packing box.
