Abstract:
A method of forming a container, comprising the steps of:(a) providing a board for forming a wall of said container, said board having a top edge, a bottom edge, an outer surface, and an inner surface, at least said outer surface having a sheet of flexible laminate attached thereon;(b) cutting a slot along a sufficient length of said inner surface to provide support for a container bottom panel, said slot being substantially parallel to the bottom edge of the board;(c) attaching a length of extrusion along the top edge of the board, said length of extrusion providing a second slot for receiving an edge of slidable container lid;(d) cutting at least three V-grooves to span between the extrusion and the bottom edge of the board so as to form two terminal folding sections and at least one intermediate folding section, each of said terminal folding sections being joined to an adjacent intermediate folding section by said flexible laminate along one edge thereof and each having an outer edge opposite said one edge thereof and each of said at least one intermediate folding section being joined to two adjacent folding sections by said flexible laminate;(e) providing a container bottom panel having an edge thickness which fits into said slot formed in step (b) and having a polygonal shape with side dimensions corresponding substantially to the lengths of the folding sections formed in said board;(f) folding said folding sections along said V-grooves so as to collapse said V-grooves, said folding sections forming a comer of the wall of said container at each collapsed V-groove; and(g) joining said outer edges of said terminal sections so as to form another corner of the wall of said container.
