  • Patent number: 5690274
    Abstract: The present invention relates to a folding box structure and in particular to a folding box structure in which a box consists of two identical components. Each of the components includes a back panel which is adjacent above to a lid panel and below to a bottom panel. The back panel adjoins on its two sides respectively an adhesive flap and a side panel. A trapezoidal-like recess is formed on the bottom panel along the outer edge. A crease is formed across from the joint of the bottom panel and the bottom side panel to the nearest vertex of the recess. Perforation is also provided along the crease for the ease of bending. These two components are engaged with each other by affixing the overlapping portions and by fitting together projections and recesses to form a box. A folding box in this structure can easily be folded and extended without further adhesion.
