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.

A self-locking container of the type incorporating a pair of side walls, and a pair of end walls, all integrally and foldably connected to a bottom wall to form a container body, a series of bellows flaps at each corner of the folded container body interconnecting intermediately each adjacent side and end wall together, said bellow flaps capable of folding into contiguity and further folding into overlying relationship against the adjacent end wall, a connecting flap foldably connecting along the upper edge of each end wall and disposed for folding over upon the bellows flaps to secure the wall and said bellows flaps into the container body form, each connecting flap incorporating tabs securing each of said flaps to its respective end wall, each series of bellows flaps when folded over ito the container configuration disposing upper edges, each disposed upper edge having at least one cut out portion, and said connecting flap tabs upon each end wall arranged for disposition within said bellows flaps cut out portions to maintain the container body into its folded form, a cover integrally connecting with and provided for the container body, said cover having end flaps, at each end, and disposed for interlocking with the approximate bellows flaps of the container body to secure said self-locking container into closure, said bellows flaps at each corner disposing an angulated edge extending from a lower outer portion of the end wall and inclined upwardly towards a central upper portion of the said end wall, said end flaps of the cover having angled portions aligned with the angulated edges of the bellows flaps, and said angled portions of the end flaps of the cover disposed for tucking under and extending adjacent to the approximate angulated inclined edges of the bellows flaps along substantially the length of and contiguous with the angulated edges of said bellows flaps when securing said container into closure.
