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.

First claim

1 . A cartridge of an electronic vaping device, the cartridge comprising:
a mouth-end insert comprising,
at least eight outlets configured to distribute vapor, 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 a temperature ranging from about 60° C. to about 70° C.

2 . The cartridge of claim 1 , wherein the temperature of the vapor exiting the outlets ranges from about 62° C. to about 66° C.

3 . The cartridge of claim 1 , wherein each 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 2 , wherein each of the outlets is angled at about 40° to about 50° in relation to the 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 diameter 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 outlets are generally tear drop in shape.

9 . The cartridge of claim 1 , wherein the eight outlets have a combined outlet area of about 12 mm 2 to about 14 mm 2 .

10 . The cartridge of claim 9 , wherein a ratio of the combined outlet area to an area of the mouth-end insert ranges from about 1:3 to about 1:6.

11 . The cartridge of claim 10 , wherein the ratio of the combined outlet area to an area of the mouth-end insert ranges from about 1:4 to about 1:5.

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

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

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

15 . The cartridge of claim 12 , wherein the downstream surface of the mouth-end insert has a beveled edge.

16 . The cartridge of claim 13 , wherein a circumference of the sidewall is less than the diameter of the downstream surface of the mouth-end insert.

17 . The cartridge of claim 12 , wherein the sidewall has a length ranging from about 3 mm to about 5 mm.

18 . The cartridge of claim 12 , wherein the sidewall has a beveled, upstream edge.

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

20 . 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.

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

22 . A cartridge of an electronic vaping device ; the cartridge comprising:
a mouth-end insert comprising,
eight outlets configured to distribute vapor, the eight outlets having a combined outlet area of about 12 mm 2 to about 14 mm 2 , 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.
