Abstract
A drainage platform supports an expendable container on a receptacle in a stable and appropriate orientation to assist in draining residual contents from the mouth of the container into the receptacle for the separate disposal of the container and the residual contents, the drainage platform including a pan with a downwardly sloping bottom and a sump with a drain, the sump being offset from the center of the drainage platform to register the drain with a corresponding offset opening in the receptacle, and a plurality of ribs establishing an essentially horizontal support for the container above the downwardly sloping bottom such that the residual contents are drained into the sump and then through the drain into the receptacle for collection and disposal of the residual contents separate from the disposal of the expendable container. A supplemental wire rack includes a base frame for resting on the horizontal support, and upwardly projecting posts for entering the mouth of the container to enhance the stability of the container placed on the horizontal support.
