摘要：PURPOSE:To increase a buffer ability and prevent bending, curving and breaking of a box, by making peaks and troughs alternately in the vertical direction to form a required corrugated rows and by using a corrugated core body with the corrugated rows meandering on a plane. CONSTITUTION:A corrugated core body 11 is formed in such a maner that an actual amplitude rate H/L of corrugate rows 13 is within 0.4-1.4, an actual meandering rate D/N is less than 0.35, an actual superposed ratio of meander D/L is more than 0.5 and a width-shifting ratio in the travelling direction of the corrugate rows is less than 8% plus a deflection ratio of the sheet materials and further the cross section of the peaks and troughs of the corrugate rows is formed to shape curved or beveled with a narrow width or shoulder-cut to define the corrugate core body 11. Moreover, a flat plate liner 12 is stuck to at least one face of the corrugate core body 11 to form a complex corrugated member 10 and a ruled line is drawn to partition four rectangular parts continuing laterally in the developed drawing in the complex corru gate core body 10. And further, an upper flap and lower flap, which can be folded independently, are fitted at the both upper and lower parts of the upper and lower ruled lines of respective rectangular partitions. In this way, bending, curving and breaking can be prevented.
