Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A method of manufacturing a multiple ply wood article comprising providing a first wood veneer ply and a second wood veneer ply, immersing said wood veneer plies in water at a temperature above about 200°F for a period sufficient to increase the flexibility of said plies, removing said plies from said elevated temperature water, forming a first wood veneer ply into a generally tubular shape with a pair of confronting ends and having a grain oriented generally in a first direction, forming a second wood veneer ply into a generally tubular shape generally similar to the shape of said first wood veneer ply with a pair of confronting ends and having its grain oriented generally in said first direction, applying adhesive means to at least one of the exterior surface of said first wood veneer ply and the interior surface of said second wood veneer ply, placing said second wood veneer ply in exteriorly disposed surface to surface adjacency with respect to said first wood veneer ply with the grain orientations of said first and second wood veneer plies being generally parallel, and securing said wood veneer plies in such relative position to establish a tubular article.
Claim 2
Independent Claim
197 words
A method of manufacturing a multiple ply wood article comprising providing a first wood veneer ply and a second wood veneer ply, immersing said wood veneer plies in water at a temperature above about 200°F for a period sufficient to increase the flexibility of said plies, removing said plies from said elevated temperature water, forming a first wood veneer ply into a generally tubular shape with a pair of confronting ends and having a grain oriented generally in a first direction, forming a second wood veneer ply into a generally tubular shape generally similar to the shape of said first wood veneer ply with a pair of confronting ends and having its grain oriented generally in said first direction, applying adhesive means to at least one of the exterior surface of said first wood veneer ply and the interior surface of said second wood veneer ply, placing said second wood veneer ply in exteriorly disposed surface to surface adjacency with respect to said first wood veneer ply with the grain orientations of said first and second wood veneer plies being generally parallel, and securing said wood veneer plies in such relative position to establish a tubular article.
Claim 3
Dependent Claim
30 words
The method of manufacturing a multiple ply composite wood article of claim 1 including said grains being oriented generally longitudinally with respect to the longitudinal axis of said tubular article.
Claim 4
Dependent Claim
36 words
The method of manufacturing a multiple ply composite wood article of claim 1 including the confronting ends of one said ply being generally nonaligned with respect to the confronting ends of said other wood veneer ply.
Claim 5
Dependent Claim
32 words
The method of manufacturing the multiple ply composite wood article of claim 1 including after completion of manufacture of said tubular article, securing a closure element to at least one end thereof.
Claim 6
Dependent Claim
34 words
The method of manufacturing the multiple ply composite wood article of claim 1 including the orientation of said wood grains on said wood veneer plies having an included angle of less than about 20°.
Claim 7
Dependent Claim
95 words
The method of manufacturing the multiple ply composite wood article of claim 1 including after forming said first and second wood veneer plies forming at least one additional wood veneer ply having a generally tubular shape, a configuration generally the same as said first and second wood veneer plies with a pair of confronting ends and a grain oriented generally in said first direction, and positioning each said additional wood veneer ply over the next preceding exteriorly disposed wood veneer ply in surface adjacency with respect thereto and adhesively securing the same in such position.
Claim 8
Dependent Claim
37 words
The method of manufacturing the multiple ply composite wood article of claim 1 including providing closures at or adjacent each end of said tubular article with at least one said closure being readily removable and reapplied thereto.
Claim 9
Dependent Claim
41 words
The method of manufacturing multiple ply composite wood article of claim 1 including prior to forming said wood veneer plies into said generally tubular shape, immersing said plies in water at about 200° to 250°F for about 1 to 10 minutes.
Claim 10
Dependent Claim
50 words
The method of manufacturing the multiple ply composite wood article of claim 1 including providing said wood veneer plies in a thickness of about 1/32 to 5/16 inch, and creating said generally tubular shape by wrapping each said ply under the influence of tension and heat around a form member.
Claim 11
Dependent Claim
45 words
The method of manufacturing the multiple ply composite wood article of claim 9 including securing said plies around said form members for a sufficient period of time to restore the moisture content of said plies generally to the level which existed prior to said immersion.
