Abstract:
1. A cushioning product comprising: an elongated paper tube having a longitudinal axis, said elongated paper tube formed from a pair of elongated sheets of paper each having a pair of lateral side edges, said pair of sheets of paper positioned in face-to-face relation such that said lateral side edges of one of said sheets of paper are in confronting relation relative to said lateral side edges of the other of said sheets of paper, each said lateral side edge of said one sheet being joined longitudinally to a respective one of said lateral side edges of said other sheet, said lateral side edges of each sheet not joined to one another, to form said tube, said tube thereby having an entire circumferential wall thickness of only a single thickness of one of said sheets of paper except where said lateral side edges of said sheets of paper overlap, said tube being crumpled along the longitudinal axis of said tube so as to have creases which are generally transverse to the longitudinal axis of said tube and which extend circumferentially around said tube, said crumpled paper tube having a generally annular cross-section with an outer diameter and an inner diameter defining a longitudinal bore of said crumpled paper tube, said crumpled paper tube having a resilience greater than that of said elongated paper tube in an uncrumpled state.
