Abstract
A mobile cart (10) is disclosed comprising a wheeled platform (12), and a plurality of uprights (18, 20, 22) extending upward therefrom to support a middle shelf (24) at an intermediate level, and an upper shelf (26) at a top level. The intermediate shelf is adapted to provide an arcuate forward surface (98) for receiving and cradling a refuse container positioned upon the wheeled platform (12) to prevent tipping of the container when the cart is turned. A handle (28) affixes to the upper shelf (26) and a bag (214) is suspended from the handle. A compartment comprising a base (30) and a cover (32) is pivotally attached to the handle to move in unison between a lowered position wherein the compartment covers the upper open end of the bag (214), and an upper position wherein the bag top is exposed. The cover and base define an internal storage compartment (156) for isolating objects from surrounding individuals as well as isolating the contents of the bag from contact with the surrounding environment.
