PROBLEM TO BE SOLVED: To provide a bottom lid for a packing box which is easy to set up and separable according to materials. SOLUTION: In the bottom lid, a bottom 12 is provided with a plurality of raisable cut-out pieces 12a and 12b, and, on the other hand, a cushion 11 is provided with insertion holes 2a and 2b for inserting the raisable cut-out pieces in and first fixing holes 2c and 2d and projections 21 and 22 for inserting and fixing the raisable cut-out pieces in, therefore the cushion 11 can be positioned and fixed on the bottom of a box body. Also, a bend part is formed by making two cuts in part of the upper end of each side wall and by bending the part between the cuts, on the other hand, a notch 2e for locking the bend part in is formed in the cushion 11 or extension parts 11e and 11f parallel with the bottom are formed on part of the upper end of each side wall, and, conversely, second fixing holes 2f and 2g for fixing the front ends of the extension parts in are made in the cushion 11. This makes it possible to fix the side walls of the box body into the cushion, set it up easily, and, further, separate the parts according to their materials. |
