Abstract
A method for filling a container with a plurality of particles or a liquid includes a bulk packaging support structure for supporting the flexible container during filling. The support structure includes first and second foldable members each having a bottom portion and a first wall section that is pivotally connected to the bottom portion along a primary fold line. A second wall section is pivotally connected to the first wall section along a secondary fold line that extends perpendicular to the primary fold line. The first and second foldable members are releasibly engaged with one another such that the bottom portion of the first foldable member is disposed between the second wall section and the bottom portion of the second foldable member. The radially flexible container disposed within the support structure is filled through a large diameter to a fill level. The large diameter of the radially flexible container is then reduced to a smaller fill diameter in vertical relationship to the fill level as the fill level rises during filling of the flexible container.
