PURPOSE: To obtain a container packaging material which is easy to assemble and connect by a manual work. CONSTITUTION: U-shape cuts 17 whose width is gradually narrowed toward the lower ends are made in an upper rim of a side wall 8a to form inverse trapezoid tack flaps 18 and insert slits 19. Inverse trapezoid insert flaps 38 are provided on a top wall 30b and connection flaps 40 are extended from the right and left sides of the insert flaps 38 with connection flap folds 41 between them. The insert flaps 38 are pushed with fingers to fold the connection flaps 40, inserted into the insert slits 19 and connected by the connection flaps 40. |
