Smoking article

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.

Description

FIELD OF THE INVENTION [0001] The present invention relates to tobacco products, such as smoking articles (e.g., cigarettes). BACKGROUND OF THE INVENTION [0002] Popular smoking articles, such as cigarettes, have a substantially cylindrical rod-shaped structure and include a charge, roll or column of smokable material, such as shredded tobacco (e.g., in cut filler form), surrounded by a paper wrapper, thereby forming a so-called “smokable rod,”“tobacco rod” or “cigarette rod.” Normally, a cigarette has a cylindrical filter element aligned in an end-to-end relationship with the tobacco rod. Preferably, a filter element comprises plasticized cellulose acetate tow circumscribed by a paper material known as “plug wrap.” Certain filter elements can incorporate polyhydric alcohols. See, for example, UK Pat. Spec. 755,475. Certain cigarettes incorporate a filter element having multiple segments, and one of those segments can comprise activated charcoal particles. See, for example, U.S. Pat....

[0013] Further features and advantages of the present invention are set forth in the following more detailed description.

Problems solved by technology

Smoking articles that employ tobacco substitute materials and smoking articles that employ sources of heat other than tobacco cut filler to produce tobacco-flavored vapors or tobacco-flavored visible aerosols have not received widespread commercial success.
