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. A vessel in accordance with the present disclosure is configured to hold a product in an interior region. In illustrative embodiments, the vessel is an insulated container such as a drink cup. In illustrative embodiments, the vessel is a container such as a shampoo bottle.

First claim

1 - 17 . (canceled)

18 . 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 floor and the side wall cooperate to form a monolithic element comprising an inner polymeric layer forming a boundary of the interior product-storage region, an outer polymeric layer arranged to lie in spaced-apart relation to the inner polymeric layer to define a core chamber therebetween, and a middle cellular non-aromatic polymeric material located in the core chamber to lie between the outer polymeric layer and the inner polymeric layer, and wherein the inner polymeric layer, the outer polymeric layer, and a middle cellular non-aromatic polymeric material cooperate to provide means for maximizing a compressive strength of the vessel as tested by top-load testing and a shear strength of the vessel as tested by side-wall rigidity testing while minimizing a weight of the vessel.

19 . The vessel of claim 18 , wherein the middle cellular non-aromatic polymeric material comprises high-density polyethylene.

20 . The vessel of claim 19 , wherein the density of the middle cellular non-aromatic polymeric material is in a range of about 0.1 g/cm 3 to about 0.185 g/cm 3 .

21 . The vessel of claim 18 , wherein the vessel has an average density in a density range of about 0.51 g/cm 3 to about 0.91 g/cm 3 .

22 . The vessel of claim 21 , wherein the compression strength of the vessel is greater than a compression strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

23 . The vessel of claim 22 , wherein the compression strength of the vessel is about 5% to about 30% greater than the compression strength of the control vessel.

24 . The vessel of claim 21 , wherein the shear strength of the vessel is greater than a shear strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

25 . The vessel of claim 24 , wherein the compression strength of the vessel is about 3% to about 30% greater the compression strength of the control vessel.

26 . The vessel of claim 21 , wherein the average density is about 0.91 g/cm 3 .

27 . The vessel of claim 26 , wherein the compression strength of the vessel is about 9% greater than a compression strength of a control vessel having a mass about the same as a mass of the vessel a shape about the same as a shape of the vessel.

28 . The vessel of claim 27 , wherein the shear strength of the vessel is about 4% greater than a shear strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

29 . The vessel of claim 21 , wherein the density range is about 0.6 g/cm 3 to about 0.8 g/cm 3 .

30 . The vessel of claim 29 , wherein the average density is about 0.61 g/cm 3 .

31 . The vessel of claim 30 , wherein the compression strength of the vessel is about 15% greater than a compression strength of a control vessel having a mass about the same as a mass of the vessel a shape about the same as a shape of the vessel.

32 . The vessel of claim 31 , wherein the shear strength of the vessel is about 15% greater than a shear strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

33 . The vessel of claim 29 , wherein the average density is about 0.71 g/cm 3 .

34 . The vessel of claim 33 , wherein the compression strength of the vessel is about 26% greater than a compression strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

35 . The vessel of claim 34 , wherein the shear strength of the vessel is about 24% greater than a shear strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

36 . The vessel of claim 35 , wherein the vessel has a mass of about 56 grams.

37 . The vessel of claim 33 , wherein the shear strength of the vessel is about 24% greater than a shear strength of a control vessel having a mass about the same as a mass of the vessel and a shape about the same as a shape of the vessel.

38 . 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 floor and the side wall cooperate to form a monolithic element comprising an inner polymeric layer forming a boundary of the interior product-storage region, an outer polymeric layer arranged to lie in spaced-apart relation to the inner polymeric layer to define a core chamber therebetween, and a middle cellular polymeric material located in the core chamber to lie between the outer polymeric layer and the inner polymeric layer, and wherein the inner polymeric layer, the outer polymeric layer, and a middle cellular non-aromatic polymeric material cooperate to maximize resistance to a collapse force while minimizing a weight of the vessel.

39 . The vessel of claim 38 , wherein the density of the middle cellular polymeric material is in a range of about 0.1 g/cm 3 to about 0.185 g/cm 3 .

40 . The vessel of claim 39 , wherein the collapse force required to collapse the vessel is greater than a collapse force required to collapse a non-cellular vessel having a shape about the same as a shape of the vessel.

41 . The vessel of claim 40 , wherein a mass of the vessel is about equal to a mass of the non-cellular vessel.

42 . The vessel of claim 41 , wherein the collapse force required to collapse the vessel is about 55% to about 65% greater than the collapse force required to collapse the non-cellular vessel.
