Abstract: A container includes an outer container that has an outer container base and outer container walls extending from the outer container base. The outer container walls have a rim forming a closed geometric shape. A ledge is formed on an inside surface of the outer container walls below the rim. An inner container has an inner container base and inner container walls. The inner container walls extend from the inner container base. The inner container has at least one aperture for conducting fluid from within the inner container to outside the inner container, preferably in the inner container base. The inner container walls have a lip. The inner container fits within the outer container and the lip engages with the ledge, holding the inner container base distal from the outer container base and forming a gap between the inner container base and the outer container base for collection of fluids.
