Abstract
A folder type paperboard container formed from a single piece having a hexagonal bottom wall panel, a rear wall panel, a front wall panel, a pair of side wall panels and a cover panel. The front wall panel includes a tuck that adds strength to the location and also serves as a securing mechanism. The securing mechanism does not extend beyond the front panel. The cover panel includes two depending flaps that cooperate with and are part of the securing mechanism. The folder type container includes an angled front panel arrangement that secures the cover in place, requires less material, and increases the strength of the center front section of the box where it generally is grasped by a handler.
