Abstract: One common problem when doing trash clean up is that the mouths of thin (often plastic) bags have a tendency to collapse when carried by hand. This collapse closes the mouth of the bag, making it difficult to place material inside. The invention comprises a frame that the bag is installed over. Attached to the frame are flaps connected to the frame via living hinges. On each flap are snaps that have corresponding matched mating parts on the frame itself. When the flaps are closed, the matched mating parts interface in such a way as to snap closed, locking the bag open securely between the flaps and frame. When built into the top of a waste bin, the invention prevents the sides of the bag from falling into the bin.
