Octagonal box structure

A blank of fiberboard material for forming an octagonal box configuration having at least an integrally formed top or bottom closure, comprising, in combination;

• a) eight side wall panels having substantially an equal height dimension integrally connected together along vertically disposed, horizontally spaced, score hinge lines which define the corners of a fully set-up box configuration;
• b) a first two pair of said side wall panels having a greater width dimension than a second two pair of said side wall panels;
• c) said second two pair of side wall panels having approximately a width dimension equal to one another and about 20 to 40 percent of the width dimension of at least the smaller of the first two pair of side wall panels, each side wall panel of said second two pair being disposed between side wall panels of said first two pair;
• d) eight closure flaps integrally connected to and depending outwardly from said side wall panels along a common generally horizontally disposed score hinge line for folding inwardly about said horizontally disposed score hinge line, each of said closure flaps having a width dimension co-extensive with the width dimension of a corresponding vertically aligned side wall panel as defined by an extension of said vertically disposed score hinge lines and each including a free edge;
• e) a pair of diagonal score hinge lines provided on each of four of said closure flaps co-extensive with said first two pair of side wall panels, each of said diagonal score hinge lines extending toward one another from an intersection of one of said extensions of said vertical score hinge lines and said common horizontal score hinge line and terminating at a free edge of a respective one of said four closure flaps to form an angle relative to one of said extensions of said vertical score hinge lines between about 20 and 25 degrees;
• wherein each of said closure flaps having a pair of diagonal score hinge lines may be folded inwardly in partial overlapping relationship upon itself and with each immediately adjacent closure flap to form a top or bottom closure.
