A funnel having a collection area disposed at one end of the funnel. A base surface of the collection area is flat. A flange surrounding an inlet opening is positioned spaced from the collection area. When the funnel is placed in a vertical orientation with the base surface of the collection area contacting a horizontal surface, a lowermost edge of the flange surrounding the inlet opening is aligned with the base surface of the collection area. The funnel is thereby supported in a vertical orientation on the horizontal surface by two contact points. In this position, the residual fluid in the funnel is transferred by gravity to collect within the collection area. No residual fluid is allowed to escape from the interior of the funnel. |
