ABSTRACT:
An infusion package that has a natural, expanded, unflattened or three-dimensional condition is folded to a flattened configuration to pack in quantity. The expanded condition gives greater internal volume by which infusion is improved and quickened. A pull string, affixed near the flattening folds, unfolds the package from its flattened configuration. To make the package, a tube can be formed into a generally tetrahedral shape by forming seams across it, each at 90.degree. to the preceding seam, severing the package so formed, and folding inward across one end seam to the tetrahedron to effect the flattening.
