example 1

[0087] A smoking article according to the invention was assembled having a closed combustible heat source and a tubular element formed from a co-laminated aluminum paper tube of 6.3 micron thickness. To test the performance of the tubular element, an infrared camera is used to measure the temperature of the heat source. A camera with temperature sensitivity from 150 degrees Celsius to 650 degrees Celsius was positioned at a distance of 0.85 meters from the smoking article and set at a frame rate of 6.15 frames per second. In the first test, the temperature of the combustible heat source was not measured by any puff taken from the smoking article. In a second test, the temperature of the combustible heat source was measured using a smoking machine after 12 puffs with a puff volume of 35 mL, a puff duration of 2 seconds, and a puff interval of 60 seconds. Conditions for smoking and smoking machine specifications are set forth in ISO Standard 3308 (ISO 3308:2000). The atmospher...

[0090] A smoking article according to the invention was assembled having a closed combustible heat source and a tubular element formed from a co-laminated aluminum paper tube of 6.3 micron thickness. The smoking article of Example 2 differs from the smoking article of Example 1 in that the tubular element further comprises a coating of Sika (RTM), Pyroplast (RTM) ST-100, water-based swelling paint on its inner surface. To test the performance of the tubular element, an infrared camera is used to measure the temperature of the heat source. A camera with temperature sensitivity from 150 degrees Celsius to 650 degrees Celsius was positioned at a distance of 0.85 meters from the smoking article and set at a frame rate of 6.15 frames per second.

Abstract

The present invention relates to a smoking article having a proximal end and a distal end. The smoking article comprises: a combustible heat source positioned at the distal end of the smoking article; an aerosol-forming substrate downstream of the combustible heat source; a mouthpiece downstream of the aerosol-forming substrate and positioned at the proximal end of the smoking article; and a tubular element slideable from a first position towards the distal end of the smoking article to a second position. In the second position the slideable element at least partially extends over the combustible heat source to reduce the air supply to the combustible heat source. The tubular element may modify the heat of the combustible heat source. It may also be used to control the resistance-to-draw of the smoking article by selectively covering air inlets.

Description

technical field [0001] The present invention relates to a smoking article having a combustible heat source for heating an aerosol-forming substrate, and an assembly for regulating the heat of the combustible heat source. Background technique [0002] A number of smoking articles in which the tobacco is heated rather than combusted have been proposed in the art. One purpose of such 'heated' smoking articles is to reduce known harmful smoke constituents of the type produced by the combustion and thermal degradation of tobacco in conventional cigarettes. In one known type of heated smoking article, aerosol is generated by transferring heat from a combustible heat source to a physically separate aerosol-forming substrate (eg, tobacco). The aerosol-forming substrate can be located within, around, or downstream of the combustible heat source. For example, WO-A2-2009 / 022232 discloses a smoking article comprising a combustible heat source, an aerosol-forming substrate downstream o...
