## Abstract

A cartridge for an electronic vaping device may include at least one inner tube along a length of the cartridge. The inner tube defines a passageway. A heating element is within the inner tube and has a longitudinal axis. A jacket at least partially surrounds the heating element. The tube segment is positioned between the heating element and the inner tube along the longitudinal axis of the heating element.

## Claims

### Claim 1

An electronic vaping device, comprising:
a power section; and
a cartridge including,
at least one inner tube along a length of the cartridge, the at least one inner tube defining a passageway,
a heating element within the at least one inner tube, the heating element having a longitudinal axis, and
a jacket at least partially surrounding the heating element along the longitudinal axis of the heating element.

### Claim 2 (depends on 1)

The electronic vaping device as recited in claim 1, wherein the jacket is a section of a tube.

### Claim 3 (depends on 2)

The electronic vaping device as recited in claim 2, wherein the jacket completely surrounds the heating element.

### Claim 4 (depends on 2)

The electronic vaping e-vaping device as recited in claim 2, wherein the jacket comprises an inlet and an outlet that define an airflow path within the jacket, the air flow path being substantially transverse to the passageway.

### Claim 5 (depends on 1)

The electronic vaping device as recited in claim 1, wherein the jacket comprises a heat insulator.

### Claim 6 (depends on 5)

The electronic vaping device as recited in claim 5, wherein the heat insulator is air impermeable and comprises one of fiberglass and ceramic.

### Claim 7 (depends on 1)

The electronic vaping device as recited in claim 1, wherein the jacket is configured to divert air flow directed toward the heating element.

### Claim 8 (depends on 1)

The electronic vaping device as recited in claim 1, wherein the jacket comprises an air permeable mesh.

### Claim 9 (depends on 1)

The electronic vaping device as recited in claim 1, further comprising:
a wick, the wick being in fluid communication with the passageway and at least a portion of the wick being within the jacket.

### Claim 10 (depends on 9)

The electronic vaping device as recited in claim 9, wherein the wick is surrounded by the heating element.

### Claim 11 (depends on 1)

The cartridge as recited in claim 1 further comprising a reservoir configured to contain a pre-vapor formulation.

### Claim 12

A cartridge comprising:
at least one inner tube along a length of the cartridge, the at least one inner tube defining a passageway;
a heating element within the at least one inner tube, the heating element having a longitudinal axis; and
a jacket at least partially surrounding the heating element along the longitudinal axis of the heating element.

### Claim 13 (depends on 12)

The cartridge as recited in claim 12, wherein the jacket is a section of a tube.

### Claim 14 (depends on 13)

The cartridge as recited in claim 13, wherein the jacket completely surrounds the heating element.

### Claim 15 (depends on 13)

The cartridge as recited in claim 13, wherein the jacket comprises an inlet and an outlet that define an airflow path within the jacket, the air flow path being substantially transverse to the passageway.

### Claim 16 (depends on 12)

The cartridge as recited in claim 12, wherein the jacket comprises a heat insulator.

### Claim 17 (depends on 16)

The cartridge as recited in claim 16, wherein the heat insulator is air impermeable and comprises one of fiberglass and ceramic.

### Claim 18 (depends on 12)

The cartridge as recited in claim 12, wherein the jacket is configured to divert air flow directed toward the heating element.

### Claim 19 (depends on 18)

The cartridge as recited in claim 18, wherein the jacket comprises an air permeable mesh.

### Claim 20 (depends on 12)

The cartridge as recited in claim 12, further comprising:
a wick, the wick being in fluid communication with the passageway and at least a portion of the wick being within the jacket.

### Claim 21 (depends on 20)

The cartridge as recited in claim 20, wherein the wick is surrounded by the heating element.

### Claim 22 (depends on 12)

The cartridge as recited in claim 12 further comprising a reservoir configured to contain a pre-vapor formulation.
