ABSTRACT:
A self locking container formed of a series of side, bottom, and end walls, all integrally folded together, and incorporating one or a pair of covers, the container generally formed of a unitary blank of paperboard or corrugated material, that may be folded into its usable configuration. Intermediate each end wall and side wall are bellows flaps, that fold contiguously into adjacency against the outer surface of each of their respective end walls, during folding of the carton, and a connecting flap formed along the upper edge of each end wall folds overlying the upper edges of the disposed proximate bellows flaps, to interlock them into position, for forming the body or lower portion of the container. One or a pair of cover parts foldably connect with the upper edge of each side wall, and when folded over into closure, dispose end flaps, at each end, which can be folded downwardly, against the proximate bellows flaps, and then tucked under the same, to provide for a fully interlocked connection between the container's cover, and its formed body portion, useful for the packaging of bulk material, such as food products, meats, or the like.
