Abstract: A first part of a plastic lid for a garbage container made of metal is secured by a standardized hinge adapter which is installed on one edge of the container. A second part of the plastic lid is slidably adjustable into and out of mating engagement with the first part to form the lid of a selected length. Three different sizes of the second part make the lid fit virtually all known containers. Depending upon the size of the container, two of the two-part slidably adjustable lids may be required to be placed next to each other in order to cover the entire opening in the container. Also, a central bar may be arranged between the two two-part slidably adjustable lids.
