Abstract
A container for flowable materials including liquids such as fruit juices and other beverages comprises a tubular body member composed of five plies bonded to each other, the first, third and fifth plies being each formed of an elongated helically wound polyolefin whose edges are overlapped and bonded with those of adjacent convolutions to form a cylindrical layer. The second and fourth plies are formed of a helically wound elongated cup paper sheet material which is thicker than the polyolefin sheet material and whose edges are in abutment with those of adjacent convolutions to form a cylindrical layer. In another container, the tubular body member is composed of a first (innermost) ply of polyolefin sheet material having overlapped convolutions, a second ply of aluminum sheet both sides of which are laminated by thin paper, a third ply of kraft paper liner having butted convolutions, and a fourth ply of polyolefin sheet material having overlapped convolutions. In yet another container, the tubular body member is composed of at least two layers, the innermost layer being formed from a sheet of synthetic resin having overlapped convolutions and provided with a continuous bond or we…
