Thin wall product display tube

1. A thin-walled polypropylene product display tube comprising a tubular member having a closed end, an open end, an inner diameter and, between the closed end and the open end, a first outer diameter, the open end terminating in a flared portion having a second outer diameter at a greatest circumference thereof, the tubular member having a wall thickness sufficient to yield a level of haze equal to or less than 8%, as measured by ASTM D1003, and a closure cap fitted to the open end, the greatest circumference of the flared portion mating with an outermost circumference of the closure cap to form a smooth transition with no ledge between the greatest circumference of the flared portion and the outermost circumference of the closure cap.

2. The thin-walled polypropylene product display tube of claim 1 , wherein the inner diameter is substantially constant from a point where the closed end expands to the inner diameter to the open end of the tubular member.

3. The thin-walled polypropylene product display tube of claim 1 , wherein the first outer diameter is substantially constant from a point where the closed end expands to the first outer diameter to a point where the flared portion begins.

4. The thin-walled polypropylene product display tube of claim 1 , wherein the closure cap comprises a plug member for engaging against an inner surface of the open end of the tubular member and substantially forming a seal.

5. The thin-walled polypropylene product display tube of claim 4 , wherein the product is a tobacco product and the seal formed by the engagement of the plug member against the inner surface of the open end of the tubular member is sufficient to maintain product shelf life for a period of at least one year.

6. The thin-walled polypropylene product display tube of claim 1 , wherein the tubular member has a wall thickness of less than about 0.061 inch.

7. The thin-walled polypropylene product display tube of claim 6 , wherein the tubular member has a wall thickness of less than about 0.050 inch.

8. The thin-walled polypropylene product display tube of claim 7 , wherein the tubular member has a wall thickness of less than about 0.030 inch.

9. The thin-walled polypropylene product display tube of claim 1 , wherein the tubular member is formed from a material comprising polypropylene random copolymer, polypropylene-ethylene impact copolymer, polypropylene homopolymer, polypropylene copolymer and blends thereof.

10. The thin-walled polypropylene product display tube of claim 9 , wherein the tubular member is formed from a material comprising polypropylene random copolymer.

11. A process for forming a thin-walled polypropylene product display tube, the process comprising forming a tubular member having a closed end, an open end, an inner diameter and, between the closed end and the open end, a first outer diameter, the open end terminating in a flared portion having a second outer diameter at a greatest circumference thereof, wherein the forming step yields the tubular member having a wall thickness sufficient to yield a level of haze equal to or less than 8%, as measured by ASTM D1003, and providing a closure cap fitted to the open end, the greatest circumference of the flared portion mating with an outermost circumference of the closure cap to form a smooth transition with no ledge between the greatest circumference of the flared portion and the outermost circumference of the closure cap.

12. The process of claim 11 , wherein the inner diameter is substantially constant from a point where the closed top end expands to the inner diameter to the open end of the tubular member.

13. The process of claim 11 , wherein the first outer diameter is substantially constant from a point where the closed end expands to the first outer diameter to a point where the flared portion begins.

14. The process of claim 11 , wherein the closure cap includes a plug member for engaging against an inner surface of the open end of the tubular member and substantially forming a seal.

15. The process of claim 14 , wherein the product is a tobacco product and the seal formed by the engagement of the plug member against the inner surface of the open end of the tubular member is sufficient to maintain product shelf life for a period of at least one year.

16. The process of claim 11 , wherein the tubular member has a wall thickness of less than about 0.061 inch.

17. The process of claim 16 , wherein the tubular member has a wall thickness of less than about 0.050 inch.

18. The process of claim 17 , wherein the tubular member has a wall thickness of less than about 0.030 inch.

19. The process of claim 11 , wherein the tubular member is formed from a material comprising polypropylene random copolymer, polypropylene-ethylene impact copolymer, polypropylene homopolymer, polypropylene copolymer and blends thereof.

20. The process of claim 19 , wherein the tubular member is formed from a material comprising polypropylene random copolymer.

21. A thin-walled polypropylene product display tube comprising a tubular member having a closed end, an open end, an inner diameter and, between the closed end and the open end, a first outer diameter, the open end terminating in a flared portion having a second outer diameter and a greatest circumference, the tubular member having a wall thickness sufficient to yield a level of haze equal to or less than 8%, as measured by ASTM D1003, and wherein the greatest circumference of the flared portion is selected to correspond to an outermost circumference of a closure cap for the tubular member such that no ledge exists between the tubular member and the closure cap.
