Abstract

A cartridge of an e-vaping device includes a housing extending in a longitudinal direction, a reservoir in the housing, a heater in the housing, and an absorbent material at least partially surrounding the sinusoidal shaped member. The reservoir is configured to store a pre-vapor formulation. The heater has a sinusoidal shaped member translating about an elliptical shape to define a channel there through. The absorbent material is in fluid communication with the reservoir.

First claim

We claim:

1. A cartridge of an e-vaping device, the cartridge comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir configured to store a pre-vapor formulation;
a first connector piece defining a first channel extending therethrough;
a post extending through the first channel, the post defining a second channel therethrough;
a heater in the housing, the heater including,
a first ring at a first end of the heater,
a second ring at a second end of the heater, and
a sinusoidal shaped member extending between the first ring and the second ring, the first ring, the sinusoidal shaped member, and the second ring being integrally formed, the second end of the heater within and connected to a portion of the post; and

an absorbent material at least partially surrounding the sinusoidal shaped member, the absorbent material in fluid communication with the reservoir.

2. The cartridge of claim 1 , wherein the absorbent material comprises a hollow, cylinder of absorbent material.

3. The cartridge of claim 1 , wherein the absorbent material comprises glass fiber.

4. The cartridge of claim 1 , further comprising:
a sheath integrally formed with an inner tube, the sheath at least partially surrounding the absorbent material, the sheath including an end wall, the end wall including at least one weep hole through the end wall, the absorbent material in fluid communication with the reservoir via the at least one weep hole.

5. The cartridge of claim 4 , further comprising:
a cylindrical member extending through the first connector piece, the cylindrical member electrically isolated from the post, the cylindrical member formed of a conductive material, and the cylindrical member in contact with at least a portion of the sheath.

6. The cartridge of claim 4 , wherein the sheath is formed of an electrically conductive material.

7. The cartridge of claim 6 , wherein the first end of the heater is in contact with a portion of the sheath.

8. The cartridge of claim 7 , wherein the sheath is electrically insulated from the post.

9. The cartridge of claim 4 , wherein the housing comprises:
an end wall that is integrally formed with the housing, the end wall including a channel therethrough, the channel in fluid communication with an air channel extending through the inner tube.

10. The cartridge of claim 9 , further comprising:
a mouthpiece configured to fit over a first end of the housing, the mouthpiece including at least one outlet in fluid communication with the channel in the end wall.

11. The cartridge of claim 2 , wherein the housing comprises:
a support tube attached to an inner wall of the housing by at least two fins, spaces between the fins forming part of the reservoir.

12. The cartridge of claim 11 , wherein a first end of an inner tube fits with an end portion of the support tube.

13. A cartridge of an e-vaping device, the cartridge comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir configured to store a pre-vapor formulation;
an inner tube in the housing, the reservoir between an inner surface of the housing and an outer surface of the inner tube, the inner tube defining an air channel therein;
a sheath integrally formed with the inner tube, the sheath having an end wall and a lateral wall, the sheath defining a heating chamber therein, the sheath defining an air passage through the end wall, and the air passage in fluid communication with the air channel;
a gasket portion within the sheath, the gasket portion including a base portion and an elongate portion, the base portion friction fitted within the lateral wall of the sheath and the elongate portion extending out of the sheath;
a heating coil in the heating chamber;
a wick in contact with the heating coil; and
an absorbent material surrounding a portion of the elongate portion of the gasket portion, the absorbent material within the sheath and in contact with the wick.

14. The cartridge of claim 13 , wherein the gasket portion defines two holes through the base portion and the cartridge further comprises:
a first electrical lead; and
a second electrical lead, each of the first electrical lead and the second electrical lead extending through one of the two holes through the base portion of the gasket portion.

15. The cartridge of claim 13 , wherein the gasket portion defines at least one flow passage through the base portion and the elongate portion, the at least one flow passage in fluid communication with the air passage and the air channel.

16. The cartridge of claim 13 , wherein the gasket portion defines at least one notch through the base portion and at least one end of the wick extends through the at least one notch.

17. The cartridge of claim 13 , wherein the gasket portion is integrally molded with a connector piece.

18. The cartridge of claim 13 , wherein the absorbent material is in fluid communication with the reservoir.

19. A cartridge of an e-vaping device, the cartridge comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir configured to store a pre-vapor formulation;
an inner tube in the housing, the reservoir between an inner surface of the housing and an outer surface of the inner tube, the inner tube defining an air channel therein;
a sheath integrally formed with the inner tube, the sheath having an end wall and a lateral wall, the sheath defining a chamber within the lateral wall, the sheath defining an air passage through the end wall, the air passage in fluid communication with the air channel;
a heater in the chamber; and
an absorbent material within a portion of the sheath.

20. The cartridge of claim 19 , wherein the heater comprises:
a first ring at a first end of the heater,
a second ring at a second end of the heater, and
a sinusoidal shaped member extending between the first ring and the second ring, and the first ring, the sinusoidal shaped member, and the second ring being integrally formed.

21. The cartridge of claim 20 , wherein the heater is a coiled heater.
