Abstract

A cartridge of an electronic vaping device includes a housing assembly and a reservoir cap assembly. The housing assembly is a single piece housing assembly. The reservoir cap assembly includes a reservoir cap having a hole there through and at least one wick extending through an opening in the reservoir cap.

First claim

We claim:

1. A cartridge of an electronic vaping device, the cartridge comprising:
a housing extending in a longitudinal direction, the housing having a first end and a second end, the housing defining at least one air passage extending longitudinally therethrough, the at least one air passage between an outer surface and an inner surface of the housing;
a reservoir cap assembly configured to be inserted in a first opening at the second end of the housing, the reservoir cap assembly including,
a reservoir cap defining a second opening, and
at least one wick extending through the second opening; and

a reservoir configured to contain a pre-vapor formulation, the reservoir at least partially defined between the inner surface of the housing and the reservoir cap assembly.

2. The cartridge of claim 1 , wherein the at least one air passage includes eight air passages spaced substantially uniformly around the housing.

3. The cartridge of claim 1 , further comprising:
a transverse end wall at the first end of the housing, the transverse end wall defining at least one outlet.

4. The cartridge of claim 1 , wherein the wick is a monolithic wick.

5. The cartridge of claim 1 , wherein the wick includes one or more slots extending longitudinally through the wick.

6. The cartridge of claim 5 , wherein the one or more slots includes at least two slots.

7. The cartridge of claim 5 , wherein the one or more slots are about 100 microns to about 400 microns wide.

8. The cartridge of claim 5 , wherein the one or more slots are evenly spaced.

9. The cartridge of claim 5 , wherein the one or more slots have same dimensions.

10. The cartridge of claim 5 , wherein the one or more slots have different dimensions.

11. The cartridge of claim 4 , wherein the wick has a height of 6 cm, a width of 3.5 mm and a length of 3.5 mm.

12. The cartridge of claim 1 , wherein the wick comprises a plurality of filaments.

13. The cartridge of claim 1 , wherein the wick is formed from materials including cellulose, glass, ceramic, graphite, a sub-combination thereof, or a combination thereof.

14. The cartridge of claim 1 , wherein the wick has a first end extending into the reservoir and a second end extending from the second opening in the reservoir cap.

15. The cartridge of claim 1 , wherein the reservoir is configured to contain 400 microliters to 1000 microliters of the pre-vapor formulation.

16. An electronic vaping device comprising:
a cartridge including,
a housing extending in a longitudinal direction, the housing having a first end and a second end, the housing defining at least one air passage extending longitudinally therethrough, the at least one air passage between an outer surface and an inner surface of the housing,
a reservoir cap assembly configured to be inserted in a first opening at the second end of the housing, the reservoir cap assembly including,
a reservoir cap defining a second opening, and
at least one wick extending through the second opening, the wick in communication with a heating element,

a reservoir configured to contain a pre-vapor formulation, the reservoir at least partially defined between the inner surface of the housing and the reservoir cap assembly; and

a power supply section including, a battery.

17. The electronic vaping device of claim 16 , wherein the at least one air passage includes eight air passages spaced substantially uniformly around the housing.

18. The electronic vaping device of claim 16 , wherein the cartridge further comprises:
a transverse end wall at the first end of the housing, the transverse end wall defining at least one outlet.

19. The electronic vaping device of claim 16 , wherein the wick is a monolithic wick.

20. The electronic vaping device of claim 16 , wherein the wick includes one or more slots extending longitudinally through the wick.

21. The electronic vaping device of claim 20 , wherein the one or more slots includes at least two slots.

22. The electronic vaping device of claim 21 , wherein the one or more slots are 100 microns to 400 microns wide.

23. The electronic vaping device of claim 20 , wherein the one or more slots are evenly spaced.

24. The electronic vaping device of claim 20 , wherein the one or more slots have same dimensions.

25. The electronic vaping device of claim 20 , wherein the one or more slots have different dimensions.

26. The electronic vaping device of claim 16 , further comprising the heating element in the power supply section.
