Flexible green nonwoven battery cover and method of construction thereof

1. A nonwoven battery cover, comprising:

a plurality of separate, circumferentially continuous nonwoven walls arranged generally concentrically with one another and partially detached from one another, each of said nonwoven walls having at least one thermally bonded seam bonding opposite edges to one another, each of said nonwoven walls being constructed from a web of mixed fibers bonded with one another via a heat-meltable material, at least one of said nonwoven walls including green material blended with said heat-meltable material; and

wherein each of said nonwoven walls has at least one hinge extending between opposite ends, each of said nonwoven walls having a first thickness and said at least one hinge having a second thickness that is less than said first thickness, wherein said plurality of nonwoven walls are bonded to one another by a welded bond joint formed across said at least one hinge.

2. The nonwoven battery cover of claim 1 wherein said heat-meltable material includes heat-meltable fibers provided from recycled plastic material.

3. The nonwoven battery cover of claim 1 wherein said at least one hinge has an increased density relative to said nonwoven walls.

4. The nonwoven battery cover of claim 1 wherein each of said nonwoven walls includes a plurality of said at least one hinge.

5. The nonwoven battery cover of claim 4 wherein each of said nonwoven walls includes a pair of said at least one seam.

6. The nonwoven battery cover of claim 5 wherein said pair of seams are arranged diametrically opposite one another.

7. The nonwoven battery cover of claim 6 wherein a pair of said hinges are arranged diametrically opposite one another.

8. The nonwoven battery cover of claim 1 wherein said plurality of nonwoven walls have at least one sealed end.

9. The nonwoven battery cover of claim 8 wherein said at least one sealed end includes material of each of said nonwoven walls melted together.

10. The nonwoven battery cover of claim 1 wherein at least one of said plurality of nonwoven walls has a different material content than another of said plurality of nonwoven walls.

11. The nonwoven battery cover of claim 1 wherein said green material includes natural fibers.

12. The nonwoven battery cover of claim 1 wherein said green material includes recycled materials.

13. The nonwoven battery cover of claim 1 wherein said green material includes waste stream materials.

14. The nonwoven battery cover of claim 1 wherein at least one of said nonwoven walls is formed without green material.
