A box or container for yams or other bulk products wherein there are closure panels having lock panels at each end thereof, and which lock panels interlock in lock notches formed in end panels carried by a bottom panel of the box. The relationship between the lock panels, which includes bent elbow hooks, and the lock notches is one wherein the required locking action is easily effected and wherein the locks may be readily released for inspection. The box preferably has a three layer end wall construction including end panels carried by the bottom panel and other end panels carried by side panels of the box. The box is readily stackable and has tapered sides and vent openings so as to permit circulation between and within stacked boxes. In one modification the box is formed from a tube, the tube being formed by joining together the ends of a unitary blank to thereby form a manufacturer\s joint, the blank defined by a plurality of hinged, articulated panels. All embodiments exhibit top closure panels which do not require stapling after container loading and which exhibit resistance to unintentional opening.
