Abstract

A cartridge of an electronic vaping device includes a housing extending in a longitudinal direction. The housing includes a sidewall, a transverse wall at the first end of the sidewall, and an inner tube integrally formed with the housing. The sidewall is generally cylindrical and a first end and a second end. The transverse wall includes at least one outlet therein. The inner tube extends in the longitudinal direction. The inner tube is concentrically positioned with respect to the sidewall. The inner tube communicates with the at least one outlet. The cartridge also includes a reservoir between the sidewall and the inner tube. The reservoir is configured to contain a pre-vapor formulation.

First claim

We claim:

1. An electronic vaping device comprising:
a cartridge including,
a housing extending in a longitudinal direction, the housing including,
a sidewall, the sidewall being cylindrical, the sidewall including a first end and a second end,
a transverse wall at the first end of the sidewall, the transverse wall including at least one outlet therein, and
an inner tube integrally formed with the housing, the inner tube extending in the longitudinal direction, the inner tube concentrically positioned with respect to the sidewall, and the inner tube in communication with the at least one outlet, and

a reservoir between the sidewall and the inner tube, the reservoir configured to contain a pre-vapor formulation,
an end cap configured to connect with the sidewall of the housing at the second end thereof, the end cap including,
an end cap sidewall, the end cap sidewall being cylindrical, and
an end wall, the end wall including a first orifice and a second orifice extending therethrough, the first orifice and the second orifice configured to be in communication with the reservoir when the end cap sidewall is received in the sidewall of the housing; and

a wick including a first end, a second end, and a central portion, the first end and the second end respectively extending through the first orifice and the second orifice in the end wall of the end cap,

wherein the end cap sidewall has a smaller outer diameter than an inner diameter of the sidewall of the housing, such that the end cap sidewall is configured to be received in the sidewall of the housing,
wherein the end wall of the end cap includes at least one inlet therein, the at least one inlet in communication with the inner tube when the end cap sidewall is received in the sidewall of the housing, and
wherein the central portion of the wick extends over the at least one inlet; and
a power supply section including,
a second housing extending in the longitudinal direction, the second housing configured to connect with the housing via a connection,
a battery in the second housing, and
a heater electrically connected to the battery,

wherein the second housing is configured to receive a portion of the cartridge therein, such that the central portion of the wick contacts the heater.

2. The electronic vaping device of claim 1 , further comprising:
a support configured to support the heater.

3. The electronic vaping device of claim 2 , wherein the support is ceramic.

4. The electronic vaping device of claim 2 , further comprising:
an insulation sleeve adjacent the support.

5. The electronic vaping device of claim 1 , wherein the wick is formed of a cellulosic material, a glass material, glass fibers, cotton, a sub-combination thereof, or a combination thereof.

6. The electronic vaping device of claim 1 , wherein the end cap further includes a third orifice and fourth orifice extending through the end wall of the end cap.

7. The electronic vaping device of claim 6 , further comprising:
a second wick, the second wick including a third end, a fourth end, and a second central portion, the third end and the fourth end extending through the third orifice and the fourth orifice, the third end and the fourth end configured to contact pre-vapor formulation contained in the reservoir, the second central portion overlapping with the central portion.

8. The electronic vaping device of claim 7 , wherein at least one of the wick and the second wick is U-shaped.

9. The electronic vaping device of claim 1 , wherein the housing is formed of plastic.

10. The electronic vaping device of claim 1 , wherein the sidewall has a first outer diameter at the first end and a second outer diameter at the second end, the first outer diameter being larger than the second outer diameter.
