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.
