<p>PURPOSE:To provide a structure for coupling wind-type assembly paper boxes or the like using no adhesive agent for simply assembly-packing mechanically or manually between a perpendicular side plate and a bottom plate wherein coupling of a claw-shaped locking piece with a coupling cut line is rigid and stable. CONSTITUTION:A claw-shaped locking piece 10 is connected to a lower end side such as a side plate via a fold line (a), a coupling cut line 11 corresponding to the claw-shaped locking piece 10 is provided on a connected side such as a bottom plate, both ends of the fold line (a) are cut into a U-shape so that they can be hooked on the side plate or the like and the claw-shaped locking piece 10, and a center of the coupling cut line 11 is bent into a flat protruding shape having a length equal to the fold line (a) with both ends cut into a U- shape, so chat the bottom plate or the like is coupled with a perpendicularly positioned side plate or the like.</p> |
