Abstract: A portable, wheeled cart foldable between stowage and deployed positions automatically captivates and suspends trash bags. A generally U-shaped and inverted main frame extends from a top forming a handle to the lower cart wheels. A companion subframe of generally U-shaped profile is pivoted to the frame. Preferably a foldable platform is provided at the cart base for supporting the trash bag. A wheel assembly axle pivotally connects the platform to the lower ends of the main frame. This allows the platform to fold and nest within the main frame thereby allowing the cart to present a compact profile for ease of storage and transport. The bag is captivated upon a pair of resilient, spaced apart clips that extend transversely across tile cart. These clips extend between and are yieldably, pivotally captivated within tipper suitable aligned orifices formed in the frame legs and the subframe legs. The clips have a mid-segment that is parallel to the handles of the cart.
