Abstract

A cartridge of an electronic Taping device includes a mouth-end insert. The mouth-end insert includes at least eight outlets configured to distribute vapor. The mouth-end insert has a surface area surrounding the outlets that is configured to absorb heat from the vapor and reduce a temperature of the vapor exiting the mouth-end insert via the outlets to a temperature ranging from about 60° C. to about 70° C.

Claims

1. A cartridge of an electronic vaping device, the cartridge comprising:

a mouth-end insert comprising,

at least eight outlets configured to distribute vapor, at least one of the outlets being generally tear drop in shape, such that a portion of the at least one of the outlets is generally pointed, the generally pointed portion of the at least one of the outlets pointing towards a center of the mouth-end insert, the mouth-end insert having a surface area surrounding the outlets that is configured to absorb heat from the vapor and reduce a temperature of the vapor exiting the mouth-end insert via the outlets to an average exit temperature ranging from about 60°

C. to about 70°

C.

2. The cartridge of claim 1, wherein the average exit temperature of the vapor exiting the outlets ranges from about 62°

C. to about 66°

C.

3. The cartridge of claim 1, wherein at least one of the outlets is angled at about 5°

to about 60°

in relation to a longitudinal axis of the cartridge.

4. The cartridge of claim 1, wherein at least one of the outlets is angled at about 40°

to about 50°

in relation to a longitudinal axis of the cartridge.

5. The cartridge of claim 1, further comprising,

an outer housing extending in a longitudinal direction, the mouth-end insert affixed within an end of the outer housing;

an inner tube within the outer housing;

a reservoir containing a pre-vapor formulation, the reservoir contained in an outer annulus between the outer housing and the inner tube;

a heater in the inner tube; and

a wick in fluid communication with the pre-vapor formulation and the heater, such that the wick delivers the pre-vapor formulation to the heater.

6. The cartridge of claim 1, wherein each of the outlets has a width ranging from about 0.015 inch to about 0.090 inch.

7. The cartridge of claim 1, wherein four of the outlets are larger than a remaining four outlets.

8. The cartridge of claim 1, wherein the eight outlets have a combined outlet area of about 12 mm² to about 14 mm².

9. The cartridge of claim 1, wherein a ratio of a combined outlet area of the outlets to an area of the mouth-end insert ranges from about 1:

3 to about 1;

6.

10. The cartridge of claim 1, wherein the ratio of the combined outlet area of the outlets to an area of the mouth-end insert ranges from about 1:

4 to about 1;

5.

11. The cartridge of claim 1, wherein the mouth-end insert has a generally cylindrical sidewall and a round downstream surface.

12. The cartridge of claim 11, wherein the downstream surface of the mouth-end insert has a diameter ranging from about 8.5 mm to about 10.0 mm.

13. The cartridge of claim 12, wherein the diameter of the downstream surface of the mouth-end insert ranges from about 9.0 mm to about 9.5 mm.

14. The cartridge of claim 11, wherein the downstream surface of the mouth-end insert has a beveled edge.

15. The cartridge of claim 12, wherein a circumference of the sidewall is less than the diameter of the downstream surface of the mouth-end insert.

16. The cartridge of claim 11, wherein the sidewall has a length ranging from about 3 mm to about 5 mm.

17. The cartridge of claim 11, wherein the sidewall has a beveled, upstream edge.

18. The cartridge of claim 1, wherein the outlets are configured to produce an average exit velocity ranging from about 1.0 m/s to about 1.2 m/s.

19. The cartridge of claim 1, wherein the outlets are configured to produce a maximum exit velocity ranging from about 2.0 m/s to about 2.2 m/s.

20. The cartridge of claim 1, wherein the mouth-end insert is formed of high density polyethylene.

22. The cartridge of claim 1, wherein the eight outlets are generally tear drop in shape, such that at least one portion of each of the outlets is generally pointed.

23. The cartridge of claim 1, wherein at least one of the outlets widens in a longitudinal direction of the cartridge extending from a mouth-end of the cartridge.

21. A cartridge of an electronic vaping device, the cartridge comprising:

a mouth-end insert comprising,

eight outlets configured to distribute vapor, at least one of the outlets being generally tear drop in shape, such that a portion of the at least one of the outlets is generally pointed, the generally pointed portion of the at least one of the outlets pointing towards a center of the mouth-end insert, the eight outlets having a combined outlet area of about 12 mm² to about 14 mm², such that a ratio of the combined outlet area to an area of the mouth-end insert ranges from about 1;

3 to about 1;

6.
