Article for use with apparatus for heating smokable material

1. An article for use with an apparatus for heating smokable material to volatilize at least one component of the smokable material, the article comprising:

a foam comprising smokable material and comprising gas dispersed in a solid medium, wherein the foam is in the form of a rod configured to allow air to be drawn in through one end, to pass through the foam, and to be drawn out of the opposite end; and

heating material that is heatable by penetration with a varying magnetic field, wherein the heating material is in thermal contact with the smokable material.

2. The article of claim 1 , wherein the solid medium comprises the smokable material.

3. The article of claim 1 , wherein the foam is an open-cell foam.

4. The article of claim 1 , wherein the foam extends from one end of the article to an opposite end of the article.

5. The article of claim 1 , wherein a first portion of the foam has a first density, wherein a second portion of the foam has a second density, and wherein the second density is greater than the first density.

6. The article of claim 5 , wherein the article is elongate, and wherein the first portion and the second portion of the foam are located at different positions along a length of the article.

7. The article of claim 1 , wherein the foam is fixed or adhered to the heating material.

8. The article of claim 1 , wherein the heating material is in the form of a body that extends from one end of the article to an opposite end of the article.

9. The article of claim 1 , wherein the heating material comprises one or more materials selected from the group consisting of: an electrically-conductive material, a magnetic material, and a magnetic electrically-conductive material.

10. The article of claim 1 , wherein the heating material comprises a metal or a metal alloy.

11. The article of claim 1 , wherein the heating material comprises one or more materials selected from the group consisting of: aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, plain-carbon steel, stainless steel, ferritic stainless steel, copper, and bronze.

12. The article of claim 1 , comprising elements dispersed through the foam, wherein each of the elements comprises heating material that is heatable by penetration with a varying magnetic field, and wherein the heating material is in thermal contact with the smokable material.

13. The article of claim 12 , wherein the elements are dispersed evenly, or substantially evenly, through the foam.

14. The article of claim 12 , wherein each of the elements comprises a closed circuit of the heating material.

15. The article of claim 1 , wherein the smokable material comprises at least one of tobacco or one or more humectants.

16. A system, comprising:

an article including a foam comprising smokable material and heating material that is heatable by penetration with a varying magnetic field, wherein the heating material is in thermal contact with the smokable material, and wherein the foam comprises gas dispersed in a solid medium and is in the form of a rod configured to allow air to be drawn in through one end, to pass through the foam, and to be drawn out of the opposite end; and

an apparatus for heating the smokable material to volatilize at least one component of the smokable material, wherein the apparatus comprises a heating zone for receiving at least a portion of the article.

17. The system of claim 16 , wherein the apparatus is for heating the smokable material to volatilize at least one component of the smokable material without combusting the smokable material.
