Smoking Article
First Claim
1. A cigarette comprising:
- a lighting end and a mouth end;
a smokable segment disposed at the lighting end, said smokable segment having a length and comprising a smokable material circumscribed by wrapping material;
a mouth end piece segment disposed at the mouth end;
an aerosol-generation system disposed between the smokable segment and the mouth end piece segment, the aerosol-generation system including (i) a heat generation segment adjacent to the smokable segment, said heat generation segment having a length and including a heat source, and (ii) an aerosol-generating segment incorporating aerosol-forming material, said aerosol-generating segment having a length and being disposed between, but physically separate from, each of the heat generation segment and the mouth end;
a single piece of outer wrapping material that provides an overwrap (i) around the aerosol-generating segment for at least a portion of its length, (ii) around the heat generation segment for the length of that segment, and (iii) around the smokable segment for at least a portion of its length;
those segments being connected together by the overwrap to provide a cigarette rod; and
the mouth end piece segment being connected to the cigarette rod using tipping material.

Abstract
A smoking article, such as a cigarette, comprises a lighting end and a mouth end. The smoking article possesses an aerosol-generation system that includes (i) a heat generation segment, and (ii) an aerosol-generating region or segment. A mouth end piece segment can be located at the mouth end of the smoking article. A segment of tobacco cut filler, gathered tobacco paper, or other type of flavor source material, can be positioned between the mouth end piece segment and the aerosol-generation segment. Optionally, segment composed of tobacco cut filler can be positioned so as to provide a lighting end segment. The smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the mouth end piece segment, the aerosol generation segment, at least a portion of the length of the heat generation segment, any segment located between the mouth end piece and aerosol generation segments, and at least a portion of the length of the optional lighting end segment. Alternatively, the smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the aerosol-generating segment, at least a portion of the length of the heat generation segment, at least a portion of any segment located downstream from the aerosol-generating segment, and at least a portion of the length of the optional lighting end segment, thereby forming a cigarette rod; and the cigarette rod is connected or attached to a filter element using a tipping type of material and arrangement.

7. A method for manufacturing a cigarette, the method comprising:
-
forming an aerosol-generating segment having two ends; forming a heat generation segment having two ends; forming a smokable segment having two ends; aligning the smokable segment, the heat generation segment and the aerosol-generating segment, such that the smokable segment is adjacent the heat generation segment, and such that the heat generation segment is adjacent the aerosol-generating segment, as to provide an aligned assembly; wrapping the aligned assembly with a single piece of outer wrapping material thereby providing an overwrap (i) around the aerosol-generating segment for at least a portion of its length, (ii) around the heat generation segment for the length of that segment, and (iii) around the smokable segment for at least a portion of its length;
those segments being connected together by the overwrap to provide a cigarette rod; andconnecting a mouth end piece segment to the cigarette rod using tipping material. - View Dependent Claims (8, 9, 10)

11. A cigarette comprising:
-
a lighting end and a mouth end; a smokable segment disposed at the lighting end, said smokable segment having a length and comprising a smokable material circumscribed by wrapping material; a mouth end piece segment disposed at the mouth end; an aerosol-generation system disposed between the smokable segment and the mouth end piece segment, the aerosol-generation system including (i) a heat, generation segment adjacent to the smokable segment, said heat generation segment having a length and including a heat source, and (ii) an aerosol-generating segment incorporating aerosol-forming material, said aerosol-generating segment having a length and being disposed between, but physically separate from, each of the heat generation segment and the mouth end; and a single piece of outer wrapping material providing an overwrap (i) around the mouth end piece segment for the length of that segment;
(ii) around the aerosol-generating segment for the length of that segment, (iii) around the heat generation segment for the length of that segment, and (iv) around the smokable segment for at least a portion of its length. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for manufacturing a cigarette, the method comprising:
-
forming an aerosol-generating segment having two ends; forming a heat generation segment having two ends; forming a smokable segment having two ends; forming a mouth piece segment having two ends; aligning the smokable segment at one end of the heat generation segment;
the heat generation segment at one end of the aerosol-generating segment, and the aerosol generating segment at one end of the mouth piece segment, so as to provide an aligned assembly; andwrapping each aligned assembly with a single piece of outer wrapping material thereby providing an overwrap (i) around the mouth end piece segment for the length of that segment;
(ii) around the aerosol-generating segment for the length of that segment, (iii) around the heat generation segment for the length of that segment, and (iv) around the smokable segment for at least a portion of its length. - View Dependent Claims (18, 19)
