A particularly effective way to attach these tabs is to provide cut lines in the side panel which the tabs engage and lock with.

Abstract: A leak proof disposable enclosed container combines a gusseted paperboard or corrugated board structure with seamless construction. The container is held erect without piercing the structure by locking tabs which enter openings in connecting panels which are foldably connected to the container walls. The top and bottom components of the container are restrained from separation by tamper tabs, which are linked to the container walls and provide anti-separative contact between the top and bottom halves of the container.

Abstract: A folded container comprises a rectangular bottom and four folded-out sides. A double walled border flange extends around the periphery of the container parallel to the bottom. The free open edges of the border flange face toward the external surfaces of the sides. The sides are connected by means of folded, triangular corner sections. Two border strips forming portions of the border flange are provided with narrow recesses which mate with correspondingly shaped projections disposed on the edges of some of the corner sections. The projections snap into the recesses upon the folding out of the sides to render the container self-supporting in the erected position for subsequent processing prior to the bonding of the individual surfaces.
