A paper board having a desired pattern and a plurality of folding lines embossed thereon defining a polygonal bottom section, an inner peripheral wall section extending outwardly from each side of the bottom section and pairs of corner sections disposed between two adjacent inner peripheral wall sections permitting the formation of a container. Wall edge, outer wall and plate sections extending outwardly from each inner peripheral wall section may be folded outwardly and downwardly to the underside of the bottom section to form hollow walls of the container.

A paper board cut into a pattern of predetermined configuration and embossed with a plurality of folding lines for permitting the board to be folded into a container, which paper board comprises: a) a bottom section having at least three peripheral edges, each of which being defined by a first folding line; b) an inner peripheral wall section adjoining each first folding line and extending outwardly from the bottom section and terminating at a second folding line; c) an extended section extending outwardly from each second folding line, each extended section further including third and fourth folding lines defining, respectively, from the second folding line a wall edge section, an outer wall section and a plate section, each wall edge section having two outer projections, each outer wall section having two inclined sides tapering outwardly from the outer projections, and each plate section being of a size substantially equal to the size of a corresponding portion of the bottom section; d) a corner section disposed between two adjacent inner peripheral wall sections, each corner section being defined by three folding lines which form two corner connection sections for heat sealing together; and e) whereby each extended section may be folded outwardly and downwardly for attaching the plate section to the underside of the bottom section and form a hollow wall of the container.
