Abstract: A refuse bin includes a frame defining an interior cavity and a seating structure. A bin liner has a biasing surface that rotationally engages the seating structure to define a recessed first position characterized by the bin liner set within the interior cavity. An elevated second position is characterized by the bin liner being vertically offset from the frame. The first position is vertically and rotationally distal from the second position. A bag retaining mechanism is defined between the frame and the bin liner. The first position defines a secured state of the bag retaining mechanism and the second position defines a maintenance state of the bag retaining mechanism.
