  • Patent number: 9611095
    Abstract: The invention is a convenient ramp-like pivotal threshold attached to a refuse container that is laid over on one side, over which to sweep debris on a floor or ground surface directly into the open end of the container. This invented threshold attachment allows the ramp threshold to be pivoted from a stored, out of the way, on the outside wall of a conventionally used refuse container standing in a vertical position, to an operating deployed position on the refuse container, laid horizontally on one side. This pivotal threshold can be removably or permanently attached to the reinforced rolled edge of the open end of a rectangular solid refuse container or to an axle that is removably or permanently attached to the curved rolled edge of the open end of a cylindrical refuse container.
