ABSTRACT OF THE DISCLOSURE A BLANK AND A BOX THEREFROM HAVING EXTENDED LIFE The blank produces a box having on at least one of its sides, near its upper portion, a hand grasping aperture substantially vertically centered with respect to the side. Between the aperture of at least one side and the top edge of this side, on the innermost ply of the fibreboard, a load diffusing reinforcing band extends along the sides, thereby defining an endless circum- ferential band enabling diffusion of the load and tear prevention of the box, and particularly on portions having critical stress points. Between the aperture of at least one side and the top edge of this side, on one of the plies of the fibreboard, but away from the innermost ply and not adjacent thereto, vis-?-vis the load diffusing reinforcing band, a constraining reinforcing band extends along the sides thereby defining an endless circumferential band constraining the sides of the box and strengthening the fibreboard above the hand grasping aperture and its vicinity, This construction provides extended life over the conventional construction.
