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

1. A multiple ply wood article comprising

a first wood veneer ply defining a generally tubular shape 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 said first wood veneer ply with a pair of confronting ends providing a second seam,

said second wood veneer ply being disposed exteriorly of said first wood veneer ply in general surface to surface adjacency,

the orientation of said grains of said wood veneer plies being such that the smaller included angle between them is less than about 20°

,

said wood veneer plies having an average thickness of about 1/32 to 5/16 inch,

adhesive means securing said first wood veneer ply to said second wood veneer ply to establish a multiple ply tubular body,

said multiple ply tubular body having no additional wood veneer ply secured directly thereto which does not have a grain oriented generally parallel with respect to the grain of said second wood veneer ply, and

said orientation of said grains being generally aligned with the longitudinal axis of said tubular body.

2. The multiple ply wood article of claim 1 including

said first and second seams being in generally nonaligned position.

3. The multiple ply wood article of claim 1 including

at least one additional wood veneer ply defining a generally tubular shape generally similar to the shape of said first and second wood veneer plies with a pair of confronting ends providing a seam,

each said additional wood veneer ply being disposed exteriorly of the next adjacent wood veneer ply in general surface to surface adjacency with respect thereto and being adhesively bonded thereto, and

all said additional wood veneer plies having a grain oriented generally parallel with respect to the grain of said second wood veneer ply.

4. The multiple ply wood article of claim 1 including

closure means secured to at least one end of said multiple ply tubular body.

5. The multiple ply wood article of claim 1 including

said wood veneer plies having a generally cylindrical tubular configuration.

6. The multiple ply wood article of claim 4 including

said article having closures at each end, and

at least one said closure being adapted for ready removal and reclosure.

7. The multiple ply wood article of claim 1 including

said adhesive means being a water repellent glue, and

said glue substantially continuously bonding said adjacent wood veneer plies.

8. The multiple ply wood article of claim 7 including

said water repellent glue having a layer thickness of about 1% to 10% of the average thickness of the plies which it bonds.

9. A multiple ply wood article comprising

a first wood veneer ply defining a generally tubular shape 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 said first wood veneer ply with a pair of confronting ends providing a second seam,

said second wood veneer ply being disposed exteriorly of said first wood veneer ply in general surface to surface adjacency,

the orientation of said grains of said wood veneer plies being such that the smaller included angle between them is less than about 20°

,

adhesive means securing said first wood veneer ply to said second wood veneer ply to establish a multiple ply tubular body, and

said multiple ply tubular body having no additional wood veneer ply secured directly thereto which does not have a grain oriented generally parallel with respect to the grain of said second wood veneer ply.
