Abstract

A vessel is configured to hold a product in an interior region formed in the vessel. In illustrative embodiments, the vessel includes a floor and a sidewall coupled to the floor to extend away from the floor. Together the floor and sidewall cooperate to define the interior region.

First claim

The invention claimed is:

1. A vessel comprising
a floor and
a side wall coupled to the floor and arranged to extend upwardly from ground underlying the floor and to cooperate with the floor to define an interior product-storage region therebetween,
wherein the side wall comprises an outer polymeric layer having an inner surface arranged to face the interior product-storage region and an outer surface arranged to face away from interior product-storage region and a cellular non-aromatic polymeric material layer having an inner surface arranged to face toward the product-storage region and an outer surface arranged to face away from the product-storage region and the outer surface of the cellular non-aromatic polymeric material is in direct engagement with the inner surface of the outer polymeric layer.

2. The vessel of claim 1 , wherein the cellular polymeric material layer comprises polylactic acid.

3. The vessel of claim 1 , wherein the cellular non-aromatic polymeric material layer comprises high-density polyethylene.

4. The vessel of claim 3 , wherein the density of the cellular non-aromatic polymeric material is in a range of about 0.1 g/cm 3 to about 0.185 g/cm 3 .

5. The vessel of claim 4 , wherein the vessel has an average density in a density range of about 0.5 g/cm 3 to about 0.9 g/cm 3 .

6. The vessel of claim 5 , wherein the outer polymeric layer comprises high-density polyethylene.

7. The vessel of claim 1 , wherein the cellular non-aromatic polymeric material layer comprises polypropylene.

8. The vessel of claim 7 , wherein the density of the middle cellular non-aromatic polymeric material is in a range of about 0.1 g/cm 3 to about 0.19 g/cm 3 .

9. The vessel of claim 8 , wherein the outer layer is extruded onto the cellular non-aromatic polymeric material layer.

10. The vessel of claim 9 , wherein the side wall further comprises a second layer coupled to the outer layer to locate the outer layer between the cellular non-aromatic polymeric material layer and the second layer.

11. The vessel of claim 1 , wherein the cellular non-aromatic polymeric material layer comprises polyethylene.

12. The vessel of claim 11 , wherein the vessel has an average density in a density range of about 0.5 g/cm 3 to about 0.9 g/cm 3 .

13. The vessel of claim 12 , wherein each of the outer polymeric layer and cellular non-aromatic polymeric material layer comprises polyethylene.

14. The vessel of claim 13 , wherein the cellular non-aromatic polymeric material layer comprises low density polyethylene.

15. The vessel of claim 13 , wherein each of the outer polymeric layer and the cellular non-aromatic polymeric material layer comprises low density polyethylene.

16. The vessel of claim 1 , wherein the outer polymeric layer is made from a material and the cellular polymeric material layer is made from a different material.

17. The vessel of claim 16 , wherein the side wall further comprises an inner layer coupled to the cellular non-aromatic polymeric material layer to locate the cellular non-aromatic polymeric material layer between the inner layer and the outer layer.

18. The vessel of claim 17 , where the inner polymeric layer is made from the material of the outer polymeric material.

19. The vessel of claim 17 , where the inner polymeric layer is made from a material different from the material of the outer polymeric layer.

20. The vessel of claim 19 , wherein the vessel has an average density in a density range of about 0.5 g/cm 3 to about 0.9 g/cm 3 .
