[0099] Example 1 - Extruded Substrates in Smoking Articles

[0100] In one embodiment, a smoking article of about 83-85 mm in length utilizes a heat source of about 12 mm in length, a substrate extruded according to the processes described herein and having a length of about 10 mm, a length of about 10 mm between the substrate and the filter element. 50mm hollow / empty tube and about 10mm long cellulose acetate filter. An exemplary extruded substrate was formed with ten outer grooves and a 0.032 inch central hole, and included the following components:

[0101] components

[0102] Can refer to Figure 7 The configuration of the illustrated cigarette 710 is used to understand the physical structure of the smoking article of Example 1.

Abstract

A cigarette includes lighting (14) and mouth ends (18). It may include a smokable segment (22) disposed at the lighting end. It also includes a mouth-end segment(65); an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment (35) adjacent the smokable segment, including a heat source (40) configured to be activated by combustion of a smokable material and an insulation layer (42), which may be formed of a non-glass material that is woven, knit, or both and (ii) an aerosol-generating segment(51) including a substrate (55), which may be monolithic and/or which may include a stitch -bonded portion, with aerosol-forming material disposed between, but physically separate from, each of the heat generation segment and the mouth end; a piece of outer wrapping material (58) 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; those segments being connected together by the overwrap (64) to provide a cigarette rod; that is connected to the cigarette rod using tipping material (78).

Description

technical field [0001] The present invention relates to products made from or derived from tobacco, or otherwise containing tobacco, and intended for human consumption. The present application specifically relates to the components and construction of segmented smoking articles. Background technique [0002] A common smoking article, such as a cigarette, has a substantially cylindrical rod-shaped structure and comprises a charge, roll, or cylinder of smokable material, such as tobacco (for example, in the form of cut filler), wrapped in cigarette paper , thus forming a so-called "smokable rod", "tobacco rod" or "cigarette rod". Typically, cigarettes have a cylindrical filter element aligned in end-to-end relationship with the tobacco rod. Preferably, the filter element comprises plasticized cellulose acetate tow surrounded by a paper material known as "plug wrap". Preferably, the filter element is attached to one end of the tobacco rod with a surrounding wrapping material...
