Abstract: A container support for supporting a plastic bag having straps is formed by two plastic elongate arm members each having slots for receiving the straps. The elongate arm members are attached to a supporting surface such as a wall or the back surface of a cabinet door by using screws or the like. The arm members are formed with cavities for storing the screws such as during shipping. The arm members are formed by vertical and horizontal reinforcing ribs which are sandwiched by solid flat plastic faces. The slots have a tapering shape with bottom portions that are wider than the adjoining portion of the slot, so that the bag straps are prevented from working out of the slots. At an end of the arm members remote from the supporting surface, apertures are formed for supporting a dowel or rod or the like to support a dish towel or the like. The arm members are also adapted for receiving a plastic shelf member having legs which fit into the slots, instead of the straps of the bag.
