Abstract: A trash bag holder which moves from a generally planar collapsed storage position automatically to an open use position in which it can be used to support a flexible wall container such as a plastic trash bag. The device includes a substantially rigid rectangular frame from which elongated support elements outwardly extend at each corner thereof. The corners are each provided with a tapered socket to receive one end of such support elements which are, in turn, connected thereto by means of an extensible cord. The support elements may thus be moved to a collapsed position generally parallel to adjacent frame elements wherein the cords are under tension and when released, will automatically move to their extended open position for receipt of a trash bag.
