## Abstract

An electronic vaping device includes a roll of material that is impregnated with or includes a coating of at least one additive. The roll of material is positioned between a heater and a mouth-end insert. The additive may include a flavorant, a pH adjusting agent, a vapor former, tobacco material, and nicotine. The roll of material may be formed of a sheet of material. A plurality of sheets of material may be included in a kit.

## Claims

### Claim 1

A cartridge of an electronic vaping device, the cartridge comprising:
a housing extending in a longitudinal direction, the housing including a mouth end and a connection end;
a reservoir containing a pre-vapor formulation, the reservoir in the housing;
a heating element in the housing, the heating element in fluid communication with the reservoir, the heating element configured to generate a vapor; and
a roll of material having a channel extending longitudinally therethrough, the roll of material including at least one of a coating and an impregnated material, the roll of material positioned in the housing such that at least some of the vapor passes through the roll of material, the roll of material being removable from the cartridge.

### Claim 2 (depends on 1)

The cartridge of claim 1, wherein the roll of material comprises at least one of a polymeric film, paper, and a film of reconstituted tobacco material.

### Claim 3 (depends on 1)

The cartridge of claim 1, wherein the roll of material is positioned between the heating element and the mouth end of the housing.

### Claim 4 (depends on 1)

The cartridge of claim 1, wherein the coating and the impregnated material each include at least one additive, the additive including at least one of a flavorant, a pH adjusting agent, a vapor former, tobacco material, and nicotine.

### Claim 5 (depends on 4)

The cartridge of claim 4, wherein the roll of material includes the coating and the impregnated material, and the coating and the impregnated material includes different additives.

### Claim 6 (depends on 4)

The cartridge of claim 4, wherein the additive is an encapsulated additive, the encapsulated additive including at least one shell layer and an inner core.

### Claim 7 (depends on 6)

The cartridge of claim 6, wherein the encapsulated additive is configured to release the additive in response to one or more of heat and moisture.

### Claim 8 (depends on 6)

The cartridge of claim 6, wherein at least one of the at least one shell layer and the inner core includes the additive.

### Claim 9 (depends on 6)

The cartridge of claim 6, wherein the encapsulated additive includes a plurality of capsules, the at least one shell layer of some of the plurality of capsules having different thicknesses from the at least one shell layer of others of the plurality of capsules so as to release the additives at different times.

### Claim 10 (depends on 6)

The cartridge of claim 6, wherein the encapsulated additive includes a plurality of capsules, the at least one shell layer of some of the plurality of capsules formed of different polymers than the at least one shell layer of others of the plurality of capsules so as to release the additives at different times.

### Claim 11 (depends on 6)

The cartridge of claim 6, wherein the encapsulated additive includes a plurality of capsules, the plurality of capsules releasing the additives at the same time.

### Claim 12 (depends on 6)

The cartridge of claim 6, wherein the encapsulated additive includes tobacco and at least one polymer, the polymer including at least one of microcrystalline cellulose, pectin, hydroxypropyl methyl cellulose, and sodium alginate.

### Claim 13 (depends on 4)

The cartridge of claim 4, wherein the pre-vapor formulation excludes nicotine and the additive includes nicotine.

### Claim 14

A kit comprising:
