Abstract

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.

Claims (27)

1. A collection funnel comprising

a body having an inlet opening and an outlet opening,

a collection area for residual fluid defined between the inlet opening and the outlet opening,

a flange extending from at least a portion of said inlet opening, and

a base surface of said collection area, the base surface of the collection area and the flange defining an aligned two point support for the body in a vertical orientation when the body is located on a horizontal surface.

2. The collection funnel according to claim 1 , wherein the base surface is flat.

3. The collection funnel according to claim 1 , wherein the base surface is spaced from the flange.

4. The collection funnel according to claim 3 , wherein the base surface is located spaced below an upper edge of the flange.

5. The collection funnel according to claim 4 , wherein a surface of the body transitions between the upper edge of the flange and the base surface of the collection area.

6. The collection funnel according to claim 1 , wherein a transfer tube is connected at one end to the outlet opening, an opposite end of the transfer tube is secured to the flange.

7. The collection funnel according to claim 6 , wherein the opposite end of the transfer tube is friction fit in a circular opening defined by the flange.

8. The collection funnel according to claim 1 , wherein a plurality of retention tabs extend from the flange for securing a transfer tube in a U-shape configuration.

9. The collection funnel according to claim 1 , wherein the collection area is located at one end of the body, and the body tapers from the collection area towards an opposite end of the body for guiding residual fluid towards the collection area when the body is in a vertical orientation.

10. The collection funnel according to claim 9 , wherein an inclined surface extends from the outlet opening towards the opposite end of the body.

11. A collection funnel comprising

a body having an inlet opening and an outlet opening,

a collection area for residual fluid defined between the inlet opening and the outlet opening,

a flange extending from at least a portion of said inlet opening, and

a base surface of said collection area, the base surface of the collection area and the flange defining an aligned two point support for the body in a vertical orientation when the body is located on a horizontal surface, said flange being spaced from the base surface and defining a gap for accommodating storage of a transfer tube.

12. The collection funnel according to claim 11 , wherein the base surface is flat.

13. The collection funnel according to claim 11 , wherein the base surface is located spaced below an upper edge of the flange.

14. The collection funnel according to claim 13 , wherein a surface of the body transitions between the upper edge of the flange and the base surface of the collection area.

15. The collection funnel according to claim 11 , wherein the transfer tube is connected at one end to the outlet opening, an opposite end of the transfer tube is secured to the flange.

16. The collection funnel according to claim 15 , wherein the opposite end of the transfer tube is friction fit in a circular opening defined by the flange.

17. The collection funnel according to claim 11 , wherein a plurality of retention tabs extend from the flange for securing the transfer tube in a U-shape configuration.

18. The collection funnel according to claim 11 , wherein the collection area is located at one end of the body, and the body tapers from the collection area towards an opposite end of the body for guiding residual fluid towards the collection area when the body is in a vertical orientation.

19. The collection funnel according to claim 18 , wherein an inclined surface extends from the outlet opening towards the opposite end of the body.
