The work aims to design a more practical and reusable military dismountable buckle packaging box, based on the analysis concerning the development of current military packaging, in order to meet the higher demand for military packaging for the rapid support of future wars. Based on the comparison of the performances of the military dismountable buckle packaging box with the existing military wooden box, the shortcomings of existing military wooden box and the economic benefits of buckle packaging box were analyzed. The cost calculation model was constructed, the technical proposal of buckle packaging box was mainly presented, and the experimental verification of the packaging box was done to propose its application scope in the military field. Compared with the existing military wooden box, the military dismountable buckle packaging box adopted the movable assembly method with buckles, which made it easy to be disassembled and assembled, take up less space and strong to bear, and the basic performance had been tested to meet requirements for military use and relevant national military standards. It could be recycled no less than 20 times, so that the cost of military packaging was effectively reduced. The military dismountable buckle packaging box has obvious advantages in using performance, economic cost and application range, enabling it to have significant military and economic benefits; and it can be widely used in our military logistics.
