Insect trap and method of making same

1. An insect trap comprising:

a flexible bag having a first edge and a second edge that are connected together at a seam; and

a nozzle secured between the edges adjacent the seam, wherein the nozzle comprises a tube defining a passageway for insects into the bag and a fin providing a transition for the edges extending over the tube from the seam.

2. An insect trap in accordance with claim 1 , wherein the fin comprises a base and a leading edge such that the fin tapers from the base toward the leading edge.

3. An insect trap in accordance with claim 2 , wherein the fin comprises a side surface that curves arcuately from the base toward the leading edge.

4. An insect trap in accordance with claim 1 , wherein the nozzle has a pair of said fins oriented in substantially opposite directions.

5. An insect trap in accordance with claim 1 , wherein the bag is shaped to stand upright when partly filled with a liquid.

6. An insect trap in accordance with claim 5 , further comprising a frame disposed within the bag to support the bag when standing upright.

7. An insect trap in accordance with claim 1 , wherein the tube comprises a bottom part disposed within the bag, the bottom part having a plurality of fingers spaced apart from one another about the passageway.

8. A method of making an insect trap, said method comprising:

positioning a nozzle between a first edge and a second edge of a flexible bag, wherein the first edge and the second edge define an opening of the bag; and

connecting the first edge to the second edge to form a seam and to secure the nozzle between the edges adjacent the seam such that a tube of the nozzle defines a passageway for insects into the bag and such that a fin of the nozzle provides a transition for the edges extending over the tube from the seam.

9. A method in accordance with claim 8 , further comprising forming the fin with a base and a leading edge such that the fin tapers from the base toward the leading edge.

10. A method in accordance with claim 9 , further comprising forming the fin with a side surface that curves arcuately from the base toward the leading edge.

11. A method in accordance with claim 8 , further comprising forming the nozzle with a pair of fins oriented in substantially opposite directions.

12. A method in accordance with claim 8 , further comprising forming the bag to stand upright when partly filled with a liquid.

13. A method in accordance with claim 12 , further comprising inserting a frame into the bag to support the bag when standing upright.

14. A method in accordance with claim 8 , further comprising forming the tube with a bottom part having a plurality of fingers spaced apart from one another about the passageway.

15. A nozzle for an insect trap having a flexible bag with a first edge and a second edge that are connectable together at a seam, said nozzle comprising:

a tube defining a passageway for insects into the bag; and

a fin providing a transition for the edges extending over the tube from the seam when the nozzle is secured between the edges adjacent the seam.

16. A nozzle in accordance with claim 15 , wherein the fin comprises a base and a leading edge such that the fin tapers from the base toward the leading edge.

17. A nozzle in accordance with claim 16 , wherein the fin comprises a side surface that curves arcuately from the base toward the leading edge.

18. A nozzle in accordance with claim 15 , wherein the nozzle comprises a pair of fins oriented in substantially opposite directions.

19. A nozzle in accordance with claim 15 , wherein the tube comprises a bottom part for insertion within the bag, the bottom part having a plurality of fingers spaced apart from one another about the passageway.

20. A nozzle in accordance with claim 15 , further comprising a flange extending from the tube, the fin disposed beneath the flange.
