Abstract
A box with a hinged lid is formed from a single sheet of cut and scored paperboard, the box being in the form of a tray having front, back and end walls and a lid which are reinforced by multiple plies of material so as to increase their rigidity, with a substantial thickness at the top edge of the front wall on which the lid is adapted to rest when closed, and with certain of the walls being reinforced by inserts, and the hinge structure joining the back wall and the multi-ply lid being such that the lid tends to close but may be readily held in an open position so as to permit access to the body of the box which is filled with a product such as cigars or similar products.
