A shipping container comprising:
- a seamless cylindrical paper tube having a central axis and first and second ends each defining an opening;
- an end closure that is received within and closes the opening defined by one of the first and second ends of the tube;
- and
- a non-roll sleeve disposed on the tube at the end of the tube defining the opening within which the end closure is received;
- wherein the non-roll sleeve has a rectangular cross-section perpendicular to the central axis of the tube when disposed on the tube, and
- wherein the non-roll sleeve disposed on the tube covers only a portion but not all of the tube, leaving a central portion of the tube exposed.
A shipping container comprising a seamless paper tube having an exposed central portion with a circular cross-section and first and second ends, wherein at least one of the first and second ends has a non-circular, polygonal cross-section, wherein the polygonal cross-section has N sides, wherein N is an integer selected from 3 to 8, wherein a plurality of foldable flaps are provided at the end with the non-circular, polygonal cross-section, and wherein the end with the non-circular, polygonal cross-section is closable by folding the flaps inwardly and securing the flaps in place to form an integral end closure.
