Abstract: The invention is directed to a safety lid that can be used with a container. The container has a collection cavity having an opening on one end. A shoulder is located in the container adjacent the opening and the shoulder extends around at least a portion of the periphery of the container. The shoulder is disposed to be substantially parallel to the opening. At least one aperture is positioned in the periphery of the container adjacent the opening. A lid is positioned in said opening to close the container. The outer periphery of the lid substantially conforms to the periphery of the opening and the lid engages in and is supported by the shoulder. At least one lug is positioned on the outer periphery of the lid and the lug is disposed to be in alignment with and to extend through the aperture in the periphery of the container. The lug engages the side of the container to prevent the lid from tipping.
