Collection funnel

摘要

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.

1. A collection funnel comprising
a body having an inlet opening and an outlet opening, an inclined surface located between the inlet opening and the outlet opening, a recessed collection area in the body for residual fluid, the recessed collection area being located between the inlet opening and the outlet opening of the body, a flange extending outwardly from at least a portion of said inlet opening, and a base surface of said recessed collection area, at least a first portion of the base surface being flat, a second portion of the base surface transitioning upwardly and inwardly from the flat first portion of the base surface to the inlet opening, the flat first portion of the base surface of the recessed collection area and an outwardly extending edge of the flange defining a plane having two support points for the body in a vertical orientation when the body is placed on a horizontal surface, the flat first portion of the base surface being configured to extend parallel to the horizontal surface and the second portion of the base surface being located above the flat first portion of the base surface when the body is vertically oriented on the horizontal surface, the outlet opening extending at an upwardly and outwardly angle with respect to the flat first portion of the base surface of the recessed collection area so that a longitudinal axis of the outlet opening extends up and is inclined away from a plane of the base surface of the recessed collection area, wherein when the funnel is placed on the horizontal surface, the inclined surface is located directly above the recessed collection area.
