Abstract: A folding wire frame includes first and second end panels and first and second pairs of hingedly coupled front and back panels, with each front and back panel also hingedly coupled to an adjacent end panel. When expanded, the folding wire frame forms a rectangular structure open at the top and bottom. Moving the two pairs of front and back panels inwardly toward one another where they are hingedly coupled allows the frame to be folded along its length in an accordion-like manner and to assume a collapsed configuration. The folded frame is adapted for insertion lengthwise in the open top of an upright refuse bag such as of paper and extends beyond the open top. The frame is then expanded, or unfolded, by grasping the front and back pairs of panels where they are hingedly coupled together and moving the front pair of panels away from the back pair of panels until the frame assumes a rectangular, semi-rigid configuration, with each panel engaging an inner surface of a side wall of the bag.
