Abstract
A thin-walled polypropylene product display tube. The thin-walled polypropylene product display tube includes 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, the tubular member having a wall thickness sufficient to yield a level of haze equal to or less than 8%. A process for forming a thin-walled polypropylene product display tube is also provided.
Claims21
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, 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.
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 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.
A thin-walled polypropylene product display tube comprising a tubular member having a closed top end, an open bottom end, an inner diameter and, between the closed top end and the open bottom end, a first outer diameter, the open bottom end terminating in a flared portion having a second outer diameter and a greatest circumference and wherein the diameter greatest circumference of the flared portion is selected to correspond to an outer diameter outermost circumference of a closure cap for the tubular member such that no ledge exists between the tubular member and the closure cap.
