Collection funnel
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. Alternately, the base surface of the collection area may support the funnel vertically by itself. 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, the inlet opening and the outlet opening being aligned and open in diametrically opposite directions at opposite ends of the body,
a recessed collection area in the body for receiving residual fluid, the recessed collection area being located between the inlet opening and the outlet opening of the body, the recessed collection area including a base having an outwardly facing surface,
at least a portion of the base surface being flat, the base surface of the recessed collection area defining a surface for supporting the body when the body is positioned on a horizontal surface, the base surface of said recessed collection area being configured to extend parallel to the horizontal surface when the body is positioned on the horizontal surface, and
the outlet opening extending at an upwardly and outwardly angle with respect to the base surface of the recessed collection area so that a central longitudinal axis of the outlet opening extends up and is inclined away from a plane of the base surface of the recessed collection area, the central longitudal axis of the outlet opening extends in the range of 10° to 20° with respect to the base surface,
a plurality of fins spaced about and extending inwardly in a radial direction from an inner sidewall of the outlet opening for contacting and retaining in position an outlet portion of a container of fluid located within said body and projecting from said inlet opening so that fluid from the container is transferred through the outlet opening.
2. The collection funnel according to claim 1 , wherein a surface of the body converges as the surface transitions toward the base surface of the recessed collection area.
3. The collection funnel according to claim 1 , wherein the recessed collection area is located at one end of the body, and the body tapers from the recessed collection area towards an opposite end of the body for guiding residual fluid towards the recessed collection area when the body is in a vertical orientation.
4. The collection funnel according to claim 3 , wherein an inclined surface extends from the outlet opening towards the opposite end of the body.
5. A collection funnel comprising a body having an inlet opening and an outlet opening, the inlet opening and the outlet opening being aligned and open in diametrically opposite directions at opposite ends of the body,
a recessed collection area for residual fluid, the recessed collection area being located between the inlet opening and the outlet opening of the body,
a base surface of said recessed collection area, at least a portion of the base surface being flat, the base surface of the recessed collection area defining a horizontal surface for supporting the body in a vertical orientation when the base surface is located on a horizontal surface,
the outlet opening extending at an upwardly and outwardly angle with respect to the base surface of the recessed collection area so that a central longitudinal axis of the outlet opening extends up and is inclined away from a plane of the base surface of the recessed collection area, the central longitudal axis of the outlet opening extends in the range of 10° to 20° with respect to the base surface, a plurality of resiliently bendable arms, each of the plurality of arms including one end that is connected to and spaced about an exterior of the outlet opening, each of the plurality of arms including another end that is freely movable through a respective opening in the side wall of the outlet opening, the plurality of arms configured for frictionally engaging an inlet port so as to securely hold the body in the inlet port, and at least a portion of the plurality of arms are extendable through the plurality of respective openings in a side wall of the outlet opening in response to contact of the at least a portion of the plurality of arms with the inlet port.
6. The collection funnel according to claim 5 , wherein the recessed collection area is located at one end of the body, and the body tapers from the recessed collection area towards an opposite end of the body for guiding residual fluid towards the recessed collection area when the body is in the vertical orientation.
7. The collection funnel according to claim 6 , wherein an inclined surface extends from the outlet opening towards the opposite end of the body.
8. The collection funnel according to claim 5 , wherein the plurality of arms include a plurality of ridges for frictionally securing the arms to the inlet opening.
9. The collection funnel according to claim 5 , wherein there are two arms.
10. The collection funnel according to claim 5 , wherein there are three arms.
