ABSTRACT:
A multiple ply wood article having a first wood veneer ply defining a generally tubular shape, which may be generally cylindrical, with a pair of confronting ends providing a first seam. A second wood veneer ply defining a generally tubular shape generally similar to the shape of the first wood veneer ply with a pair of confronting ends providing a second seam. The second wood veneer ply being disposed exteriorly of the first wood veneer ply in general surface to surface adjacency. The grain orientations of the first and second wood veneer plies being oriented generally parallel with respect to each other. Adhesive means securing the wood veneer plies to establish a multiple ply tubular body. The first and second seams are preferably in generally relative nonaligned position. Additional wood veneer plies having similar structural features may be secured over the first two plies. Closure elements may be secured to one or both ends of the tubular body in order to establish a container.
A method of manufacturing the multiple ply wood article described above including preforming the first and second wood veneer plies into the desired general shape, applying adhesive to at least one of the two surfaces to be bonded and securing the two plies in surface to surface adjacency with the grains being oriented generally parallel. Additional plies may be preformed and simultaneously or sequentially bonded to create additional plies in the tubular body.
