  • front and back wall panels each having top edges, bottom edges joined together and a pair of side edges;

    a pair of side wall panels each joined to said side edges of one of said front wall panels and one of said back wall panels by a score line along the entire length of said side edges, said side wall panels being shaped to maintain said front and back wall panels in spaced apart relationship such that said side edges of said front and back wall panels joined by said side wall panels extend substantially parallel to one another from said top edges for a portion of the height of said side wall panels, said side wall panels then tapering such that said side edges bend inwardly to meet at the point at which said bottom edges of said front and back wall panels are joined, said side wall panels further including a central longitudinal score and a pair of weakening scores extending diagonally upwardly, from the locations at which said side panels begin to taper, to said central longitudinal score so as to form the shape of a diamond with the tapering portions of said side wall panels;

    said side edges of said front wall panel converging in the plane of said front wall panel toward one another from said top edge of said front wall panel to the location at which said side wall panels begin to taper, and then diverging from one another to said bottom edge of said front wall panel; and

    said side edges of said back wall panel converging in the plane of said back wall panel toward one another from said top edge of said back wall panel to the location at which said side wall panels begin to taper, and then diverging from one another to said bottom edge of said back wall panel.
