Embodiment 1-4

[0092] Embodiment 1-4——composite tobacco ball embodiment

[0093] In one embodiment, four composite tobacco pellet matrices are formed according to the methods described herein, and they include the following components:

[0094]

[0095]

[0096] The tobacco blend powder was a blend of 50% flue-cured tobacco, 30% burley tobacco and 20% oriental tobacco. Tobacco was ground to a particle size of about 10 microns. Calcium carbonate is a precipitated aggregated calcium carbonate.

Embodiment 5-8

[0097] Embodiment 5-8——Example of Flavor Compound Tobacco Ball

[0098] In another embodiment, four flavored compound tobacco pellet matrices are formed according to the methods described herein, and they include the following components:

[0099]

[0100] The tobacco blend was a blend of 50% flue-cured, 30% burley and 20% oriental tobacco. Tobacco was ground to a particle size of about 10 microns. Calcium carbonate is a precipitated calcium carbonate aggregate.

[0101] Binders may be added to any of the embodiments described above (eg, Examples 1-8 or any of the others). Binders may include, for example, CMC, gums (eg, guar gum), xanthan gum, pullulan, or alginates. The binder may preferably be added in a range from about 0 to about 15% based on the total weight of the final mixture.

[0102] Cigarettes of the present invention may be air diluted or ventilated such that the amount of air dilution used in an air diluted cigarette may be from about 10% to about 80%. ...

Abstract

A cigarette includes lighting and mouth ends. It may include a smokable segment disposed at the lighting end. It also includes a mouth-end segment; an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment adjacent the smokable segment, including a heat source and an insulation layer and (ii) an aerosol-generating segment including a substrate, which may include tobacco pellets and aerosol-forming material disposed in a substrate cavity between the heat generation segment and the mouth end; a piece of outer wrapping material that provides an overwrap around at least a portion of the aerosol-generating segment, the heat-generation segment, and at least a portion of the smokable segment and includes a foil strip laminated thereon; those segments being connected together by the overwrap to provide a cigarette rod; ; that is connected to the mouth-end segment using tipping material.
