Abstract

An e-vaping device includes a first cartomizer section including a housing body with an inner tube extending longitudinally within the housing. A tubular reservoir for storing an e-vaping liquid is positioned between the housing body and the inner tube, with a wick in fluid communication with the tubular reservoir. A heater is configured to vaporize the e-vaping liquid in the wick. The tubular reservoir is helically wound around the inner tube, and a vent hole is included in a distal end of the tubular reservoir. A cross-sectional diameter of the wick equals a cross-sectional diameter of the tubular reservoir.

Claims

1. A cartomizer, comprising:

a housing body;

a hollow inner body extending longitudinally within the housing body;

a tubular reservoir configured to store an e-vaping liquid, at least a portion of the tubular reservoir disposed between the housing body and the inner body, the tubular reservoir being wound around the inner body;

a wick in fluid communication with the tubular reservoir; and

a heater configured to vaporize e-vaping liquid in the wick.

2. The cartomizer of claim 1, wherein the tubular reservoir is helically wound around the inner body.

3. The cartomizer of claim 2, wherein the tubular reservoir is made from a flexible material that is collapsible such that a distal end of the tubular reservoir is configured to collapse as the e-vaping liquid is consumed.

4. The cartomizer of claim 3, wherein the distal end of the tubular reservoir defines a vent hole.

5. The cartomizer of claim 4, wherein a cross-sectional diameter of the wick is about equal to a cross-sectional diameter of the tubular reservoir.

6. The cartomizer of claim 1, wherein a distal end of the tubular reservoir defines a vent hole.

7. The cartomizer of claim 6, wherein a cross-sectional diameter of the tubular reservoir is between about 1.0 mm and about 3.0 mm, and a diameter of the vent hole is between about 100 micrometers and about 300 micrometers.

8. The cartomizer of claim 6, wherein the tubular reservoir is made from a rigid material.

9. The cartomizer of claim 6, wherein a cross-sectional diameter of the wick is about equal to a cross-sectional diameter of the tubular reservoir.

10. The cartomizer of claim 1, wherein a cross-sectional diameter of the wick is about equal to a cross-sectional diameter of the tubular reservoir.

11. An e-vaping device, comprising:

the cartomizer of claim 1; and

a power supply electrically connected to the cartomizer.

12. A cartomizer, comprising:

a housing body;

a hollow inner body extending longitudinally within the housing body;

a tubular reservoir configured to store an e-vaping liquid, at least a portion of the tubular reservoir disposed between the housing body and the inner body, a distal end of the tubular reservoir defining a vent hole;

a wick in fluid communication with the tubular reservoir; and

a heater configured to vaporize e-vaping liquid in the wick, wherein a cross-sectional diameter of the wick is about equal to a cross-sectional diameter of the tubular reservoir.

13. The cartomizer of claim 12, wherein a cross-sectional diameter of the tubular reservoir is between about 1.0 mm and about 3.0 mm, and a diameter of the vent hole is between about 100 micrometers and about 300 micrometers.

14. A cartomizer, comprising:

a housing body;

a hollow inner body extending longitudinally within the housing body;

a tubular reservoir configured to store an e-vaping liquid, at least a portion of the tubular reservoir disposed between the housing body and the inner body;

a wick in fluid communication with the tubular reservoir, a cross-sectional diameter of the wick being about equal to a cross-sectional diameter of the tubular reservoir; and

a heater configured to vaporize e-vaping liquid in the wick, wherein the tubular reservoir is made from a rigid material, a distal end of the tubular reservoir defining a vent hole.

15. The cartomizer of claim 14, wherein a cross-sectional diameter of the tubular reservoir is between about 1.0 mm and about 3.0 mm, and a diameter of the vent hole is between about 100 micrometers and about 300 micrometers.
