A box structure formed from a blank covered on one side thereof with a first paper wrap, the box structure comprising a substantially flat central portion, side walls adjacent to and substantially perpendicular to a first pair of opposite edges of the central portion, each of said side walls comprising a double layer of material formed by folding a marginal portion of the blank onto itself such that the first paper wrap covers the interior surfaces of said walls, each of said side walls also having a pair of double layer and extensions of substantially the same size and adapted to be sent inwardly and joined to form the interior end walls of the box, each of said interior end walls having an upper portion and a lower portion, and exterior end walls adjacent to and substantially perpendicular to a second pair of opposite edges of the central portion, each said pair of double layer end extensions being joined to form an interior end wall of the box at substantially the midpoint of the adjacent exterior end wall of the box, each of said exterior end walls including an end wall lip adapted to be bent inwardly over and to cover the upper portion of each of said interior end walls to form a box having the first paper wrap extending over the entire exterior surface of the box and continuing over each interior end wall of the box and along the interior surface of each of said side walls to one edge of said first pair of opposite edges of the central portion of the box.
