ABSTRACT:
An apparatus for insertion into and expansion of a soft bag or backpack has a relatively flat foldable member comprising three parallel fold lines forming four panels. A rubber band is connected across two of the panels so as to urge the member to fold along the fold lines therebetween. The bag is caused to be expanded by the apparatus when the rubber bands urge the member to fold into an expanded state when the bag is removed from its carton. One panel of the device is of the size and shape of a major face of the bag and is provided with a large hinged flap which, when in the expanded state is caused to form a structure having a triangular cross section.
