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.

Dependent claims

A drainage platform for supporting a container on a receptacle in a stable and appropriate orientation to assist in draining contents from the container downwardly in an essentially vertical direction into the receptacle, the container having a mouth through which the contents drain, the drainage platform comprising:

a pan having an outer peripheral rim and an inner sump, the pan including a bottom sloping downwardly between the rim and the sump, and a drain in the sump;
and
a plurality of ribs having basal portions extending along the downwardly sloping bottom of the pan, and support portions extending essentially horizontally above the downwardly sloping bottom such that upon juxtaposition of the draining platform with the receptacle, the container is received in stable placement on the essentially horizontal support portions of the ribs, such that the contents are drained in the vertical direction essentially normal to the support portions with the mouth of the container confronting the downwardly sloping bottom of the pan, to drain the contents from the container to the pan and conduct the drained contents to the sump and through the drain to the receptacle.
