The work aims to design a gift box package that can make full use of the processing materials. The gift box was designed by one page cardboard. Considering the aesthetics, the gift box adopted a regular hexagonal prism structure. Handle and locking structures were designed to improve the portability and stack stability. When the width of the two half lid interlocking part b, the handle structure height h1, the length of the bottom of the gift box l and the height h satisfied certain relations, the cardboard could be fully utilized. When l∶h∶b∶h1=1.732∶1∶1.5∶1.5, the gift box produced the least surplus material when designed from outside to inside. When l≤1.732h, h1=3h?0.866l, and b=4.5h?0.866l, the gift box produced the least surplus material by when designed from inside to outside. When l﹥1.732h and h1=b=0.866l, the gift box produced the least surplus material. The appearance of the gift box is regular hexagonal prism which is beautiful and generous. The gift box can not automatically open because of the locking structure. The handle and lid design make the gift box easy to carry and improve the stacking stability. The design of the flap is not bonded with adhesive, which is environmentally friendly.
