Smoking article for use with an internal heating element

Abstract

A smoking article for use in an aerosol-generating device includes an aerosol-forming substrate located at an extreme upstream end of the smoking article; and a support element located immediately downstream of the aerosol-forming substrate. The support element abuts the aerosol-forming substrate and the aerosol-forming substrate is configured to be penetrable by a heating element of an aerosol-generating device having a diameter of between about 40 percent and about 70 percent of the diameter of the aerosol-forming substrate without substantial deformation of the smoking article. The support element is configured to resist downstream movement of the aerosol-forming substrate during insertion of the heating element of the aerosol-generating device into the aerosol-forming substrate.

Description

technical field [0001] The present specification relates to a smoking article comprising an aerosol-forming substrate for generating an inhalable aerosol when heated by an internal heating element of an aerosol-generating device. The specification also relates to a method of using such a smoking article. Background technique [0002] A number of smoking articles have been proposed in the art in which tobacco is heated without being combusted. One purpose of such "heated" smoking articles is to reduce known noxious smoke constituents produced by the combustion and thermal degradation of tobacco in conventional cigarettes. [0003] Typically, in such heated smoking articles, aerosols are generated by heat transferred from a heat source to a physically separate aerosol-forming substrate or material, which may be located within, around, or within the heat source. downstream. During smoking, volatile compounds are released from the aerosol-forming substrate by heat transfer fr...

Problems solved by technology

EP 2 395 520 A1 discloses that in order for the smoker to smoothly insert the heater into an ordinary filter cigarette with a diameter of 8 mm, the diameter of the heater is required to be 2.3 mm or less, and EP 2 395 520 A1 also discloses an attempt Inserting a heater with a diameter greater than 2.3mm into an ordinary filter cigarette with a diameter of 8mm will cause the contour of the filter cigarette to be deformed or cause the paper of the filter cigarette to tear

[0013] However, while reducing the diameter of the internal heating element as described in EP 2 395 520 A1 facilitates the insertion of the internal heating element into the aerosol-forming matrix of the heated smoking Potential disadvantages associated with electric smoking systems for aerosol generating devices with internal heating elements
