Abstract

An aerosol-generating component for an aerosol-generating article is provided, the aerosol-generating component including: a combustible heat source; an aerosol-forming substrate; and a heat-transfer element disposed between the combustible heat source and the aerosol-forming substrate, the heat-transfer element including a cup-shaped receptacle defining a cavity, and the aerosol-forming substrate forms a coating on at least a portion of an inner surface of the cup-shaped receptacle. An aerosol-generating article including the aerosol-generating component, and a method of manufacturing the aerosol-generating component are also provided.

Claims (25)

1. An aerosol-generating component for an aerosol-generating article, the aerosol-generating component comprising:

a solid combustible heat source;

an aerosol-forming substrate; and

a heat-transfer element disposed between the combustible heat source and the aerosol-forming substrate,

wherein the heat-transfer element comprises a cup-shaped receptacle defining a cavity, the aerosol-forming substrate forms a coating on at least a portion of an inner surface of the cup-shaped receptacle, and the combustible heat source is secured to the heat-transfer element.

2. The aerosol-generating component according to claim 1 ,

wherein the heat-transfer element further comprises opposing first and second surfaces, the opposing first surface being the inner surface of the cup-shaped receptacle on which the aerosol-forming substrate forms the coating, and

wherein the combustible heat source contacts at least a portion of the opposing second surface directly opposite the portion of the first surface on which the aerosol-forming substrate forms the coating.

3. The aerosol-generating component according to claim 1 , wherein the cavity comprises an open end that is closed with a lid, the lid being removably secured to the heat-transfer element.

4. The aerosol-generating component according to claim 1 , wherein:

the heat-transfer element further comprises two opposing cup-shaped receptacles, a first cup-shaped receptacle defining a first cavity and a second cup-shaped receptacle defining a second cavity,

the aerosol-forming substrate forms a coating on at least a portion of an inner surface of the first cup-shaped receptacle, and

the combustible heat source contacts at least a portion of an inner surface of the second cup-shaped receptacle.

5. The aerosol-generating component according to claim 4 , wherein at least one of the first cavity and the second cavity is closed with a lid.

6. The aerosol-generating component according to claim 1 , wherein the heat-transfer element further comprises one or more protrusions extending at least one of towards and away from the combustible heat source.

7. The aerosol-generating component according to claim 6 , wherein the aerosol-forming substrate forms a coating on at least a portion of a surface of one or more of the protrusions.

8. The aerosol-generating component according to claim 6 , wherein the combustible heat source contacts at least a portion of a surface of the one or more protrusions.

9. The aerosol-generating component according to claim 1 , wherein the heat-transfer element is formed of a single piece of heat-conductive material.

10. The aerosol-generating component according to claim 1 , wherein the aerosol-forming substrate comprises tobacco.

11. An aerosol-generating article comprising an aerosol-generating component according to claim 1 .

12. The aerosol-generating article according to claim 11 , further comprising a holder configured to receive the aerosol-generating component.

13. A method of manufacturing an aerosol-generating component according to claim 1 , the method comprising:

positioning a portion of combustible material relative to a portion of heat-conductive material;

pressing the portion of heat-conductive material and the portion of combustible material together to form the combustible heat source and the heat-transfer element, the heat transfer element comprising a cup-shaped receptacle defining a cavity; and

applying a coating of an aerosol-forming material to a least a portion of an inner surface of the cup-shaped receptacle to form the aerosol-forming substrate.
