Abstract: A kit comprising: an aerosol generating article (2) comprising a combustible heat source (4) and an aerosol-forming substrate (10); and a retainer (300) for the aerosol generating article, the retainer comprising: a tubular body (302) having a partially-closed first end (304a) and an open second end (304b), wherein the body defines a longitudinal passage (305) extending between the first end and the second end and wherein the body comprises: a first portion (307) proximate the first end comprising a plurality of openings (306); and a second portion (309) between the first portion and the second end, wherein the body is configured to at least partially receive the aerosol-generating article in the passage such that the first portion of the body surrounds the combustible heat source of the aerosol-generating article, wherein the first end and the first portion of the body are configured such that at least about 80 percent of the exposed surface area of the combustible heat source of the aerosol-generating article remains exposed through the first end and the plurality of openings in the first portion of the body when the aerosol-generating article is received in the passage such that the first portion of the body surrounds the combustible heat source of the aerosol-generating article, and wherein the ratio of the inner diameter of the first portion of the body to the outer diameter of the exposed surface of the combustible heat source is at least about 1.1.

Abstract: A multi-segment component for an aerosol-generating article is provided, the multi-segment component including: a combustible heat source; an aerosol-forming substrate downstream of the combustible heat source; and a wrapper circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate, a front portion of the combustible heat source extending beyond the wrapper so that the front portion of the combustible heat source is exposed during use; and an intumescent coating on all or part of the front portion of the combustible heat source, the intumescent coating being configured to form a heat insulating layer on the front portion of the combustible heat source in response to heating by the combustible heat source.
