Abstract

A capless closure device including a body, an end plate provided with a circular opening adapted for receiving a fuel nozzle, and a flap door adapted to close the circular opening, where the capless closure device includes a latch edge arranged at the lower edge of the circular opening and a spaced apart sealing edge, and where an inlet drain opening is arranged between the latch edge and the sealing edge. The advantage of the invention is that a capless closure device with an integrated drain passage is provided in a cost-effective way.

First claim

The invention claimed is:

1. A capless closure device comprising a body extending along a centre line thereof, an end plate provided with a circular opening adapted for receiving a fuel nozzle, and a flap door adapted to close the circular opening, wherein the capless closure device comprises a latch edge arranged at a lower edge of the circular opening and a sealing edge spaced apart from the latch edge in a direction perpendicular to the centre line of the body, wherein the latch edge and the sealing edge are positioned in a same plane, wherein an inlet drain opening is arranged between the latch edge and the sealing edge, wherein the end plate comprises a bearing surface adapted to receive a rubber sleeve of a fuel nozzle, wherein the outlet drain opening is positioned in the bearing surface.

2. The device according to claim 1 , wherein the flap door comprises a recess arranged at the inlet drain opening when the flap door is in a closed state.

3. The device according to claim 1 , wherein the flap door comprises a circumferential sealing adapted to cooperate with the sealing edge.

4. The device according to claim 1 , wherein the latch edge and the sealing edge are positioned in the same plane perpendicular to the centre line of the body.

5. The device according to claim 4 , wherein the flap door comprises a circumferential sealing adapted to cooperate with the sealing edge.

6. The device according to claim 1 , wherein the inlet drain opening is connected to an outlet drain opening by a drain passage.

7. The device according to claim 6 , wherein the drain passage is inclined with respect to the centre line of the body with an angle between 30 to 60 degrees.

8. A vehicle comprising the device according to claim 1 .

9. The vehicle according to claim 8 , wherein the capless closure device is mounted with an angle in the vehicle, such that the centre line of the body of the capless closure device is inclined with respect to a horizontal plane of the vehicle.

10. The vehicle according to claim 9 , wherein the centre line of the body of the capless closure device is inclined by between 25 to 45 degrees with respect to the horizontal plane of the vehicle.

11. A capless closure device comprising a body extending along a centre line thereof, an end plate provided with a circular opening adapted for receiving a fuel nozzle, and a flap door adapted to close the circular opening, wherein the capless closure device comprises a latch edge arranged at a lower edge of the circular opening and a sealing edge spaced apart from the latch edge in a direction perpendicular to the centre line of the body, wherein an inlet drain opening is arranged between the latch edge and the sealing edge, wherein the end plate comprises a bearing surface adapted to receive a rubber sleeve of a fuel nozzle, wherein the outlet drain opening is positioned in the bearing surface.

12. The device according to claim 11 , wherein the latch edge and the sealing edge are positioned in a same plane perpendicular to the centre line of the body.

13. The device according to claim 11 , wherein the flap door comprises a recess arranged at the inlet drain opening when the flap door is in a closed state.

14. The device according to claim 11 , wherein the inlet drain opening is connected to an outlet drain opening by a drain passage.

15. The device according to claim 14 , wherein the drain passage is inclined with respect to the centre line of the body with an angle between 30 to 60 degrees.
