ABSTRACT:
A self-expanding filler, preferably of cardboard, for use in stuffing soft items, such purses and backpacks for display purposes at the retail outlet after being shipped flat with the item, which includes two structural members, each of which includes several panels, adjacent panels being pivotally connected to each other about their common boundary. Each of the panels includes a slot set off from the common boundary and extending parallel to the common boundary from a point on the edge of the panel, so that corresponding panels of the two structural members can interlock. The filler further includes an elastic cord, such as a rubber band which is connected to interlocking panels of the two structural members which acts to urge the interlocking panels to orient themselves substantially perpendicular to each other when they not constrained to lie flat against each other, as during shipping.
