ABSTRACT:
A bag stuffer for an expandable bag includes an insert defining a pair of substantially planar elements movable from a collapsed orientation enabling compact storage of the expandable bag to an expanded orientation providing a commercial display thereof. The insert is biased to the expanded orientation but a releasable restraint, disposed about the insert and at least partially within the expandable bag, restrains movement of the insert from the collapsed orientation to the expanded orientation. The restraint is preferably a loop of a flexible strip formed by heat sealing one end of the strip to a strip portion adjacent the other end of the strip at at least one point to define a rupturable heat-seal bond. The insert is preferably biased to the expanded orientation by a coil spring having a pair of opposed ends and at least one coil therebetween, each end of the spring passing through a respective one of the planar elements with at least a substantial portion of one coil disposed outwardly of the respective planar element for movement therewith. The insert preferably includes first, second and third substantially planar elements disposed in series parallel to one another, and is biased by a first biasing element substantially disposed intermediate the first and second planar elements and acting to separate the same and a second biasing element substantially disposed intermediate the second and third planar elements and acting to separate the same.
