Abstract
The present invention relates to composite paperboard containers and methods for making the same. Specifically, the present invention includes a curvilinear container comprising a tubular body formed convolutely or via spiral winding from a single paperboard ply or multiple plies as commonly known in the art. The tubular body includes opposing ends that can be sealed by paperboard, metallic, plastic, or membrane-type end closures so as to preserve the consumable products typically enclosed by the container. The curvilinear container includes a tubular body having a curvilinear portion wherein the diameter of the tubular body varies along the length of the curvilinear portion. A plurality of radially projecting ribs are distributed about the circumference of the curvilinear portion as collection areas for excess tube wall material and thereby accommodate reduction of the tube wall diameter within the curvilinear portion.
