ABSTRACT:
An octagonal box structure comprising eight upstanding side wall panels and eight closure flaps integrally connected to one another and to the side wall panels for folding inwardly along a generally horizontal score hinge line to close an end of the box structure. The side wall panels include four smaller panels having a width dimension of about 20 to 40 percent of the width dimension of the narrowest pair of the remaining four side wall panels. The closure flaps have a width corresponding to the width of the side wall panel from which they depend. Four of the closure flaps include diagonally extending score hinge lines to permit each of these closure flaps to fold inwardly in partial overlapping relationship upon itself and the next adjacent closure flap to form a closed end of the box. The diagonal score lines are formed at an angle between about 20 to 25 degrees relative to an extension of the vertical score lines which define the width of each closure flap.
