PROBLEM TO BE SOLVED: To provide a corner pad which can be fixed without using paste with wastepaper as a material. SOLUTION: The corner pad is formed by folding an a-side plate 2 and b-side plate 3 at a right angle via a back fold line 1, making an a-bottom plate 5 and a b-bottom plate 6 by folding a bottom fold line 4 at a right angle, and connecting the bottom plates with each other by fitting a fitting protrusion 7 into a fitting recess 7. Since a material is wastepaper, it can be incinerated with no problem. Since the fitting protrusion is fitted into the fitting recess, the a-bottom plate and the b-bottom plate are in contact along their hypotenuses, while since the back fold line can hold a right-angled folded state, a corner pad shape can be held without using paste. |
