  • AEROSOL GENERATING ARTICLE WITH RETRACTABLE HEAT SOURCE
    Publication number: 20210052011
    Abstract: An aerosol generating article (100) having a proximal end (102) and a distal end (104), comprising an inner tubular element (105) having a mouthpiece end (107) and an opposed heat source end positioned at the distal end of the aerosol generating article, and an outer tubular element (130) extending from the proximal end of the aerosol generating article towards the distal end thereof. The inner tubular element comprises an inner wrapping sheet (109) circumscribing, in a co-axial arrangement: a combustible heat source (115) positioned towards the distal end of the aerosol generating article; an aerosol-forming substrate (120) downstream of the combustible heat source; and, typically, a void space (125) between the aerosol-forming substrate and the mouthpiece end. The outer tubular element typically circumscribes at least the mouthpiece end of the inner tubular element and the void space and terminates downstream of the heat source.
