Abstract
Abstract A refuse container lid system for providing easily replaced interchangeable covers for the top of a refuse container, in which similar size covers are used on containers of various volumes. A stationary plate is used to cover the portion of the top of the container not covered by the openable covers, and the size of the plate varies depending upon the size of the container. Hinge plates are attached to the side of the container, and have studs extending into tubular ends of the plate and covers. If two covers are used side by side, a pipe is disposed between the tubular portions of the covers, and the studs are disposed in the pipe. The hinge plate is adjustably connected to a bracket on the side of the container and can be removed to replace one or both of the covers.
