Apparatus facilitating the use of a plastic grocery bag as a trash container may take the form of an adapter for supporting the plastic grocery gag in a condition for receiving trash, a trash can for supporting the plastic bag as a liner therein or a clip for securing the plastic bag within a trash can. The adapter form of the apparatus includes a ring adapted to be snugly received by the opening of the plastic bag and a plurality of spike-like formations for puncturing the walls of the plastic bag and for thereby suspending the plastic bag from the adapter. Furthermore and inasmuch as each plastic grocery bag commonly includes a pair of handle-providing apertures adjacent the opening of the bag, the adapter includes a pair of hook-like projections intregally connected to the ring for projecting through the handle-providing apertures of the bag permitting the bag and ring to be suspended across the mouth of a trash can. The trash can form of the apparatus includes a plurality of spike-like formations positioned adjacent the mouth of the trash can and arranged so as to project generally inwardly of the can. When a plastic bag is operatively positioned within the trash can so that its edge portions are hooked about the spike-like formations, the plastic bag is suspended within the trash can so as to provide a liner therefor. The clip form of the apparatus includes a pair of arm portions adapted to be positioned about an edge of the mouth of a trash can and an edge portion of the bag draped across the mouth edge for clipping the bag to the trash can.
