Abstract

Disclosed is an article for use with apparatus for heating smokable material to volatilize at least one component of the smokable material, the article including: a malleable container defining a cavity; a mass of smokable material in the cavity; and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material. Also disclosed is a system including: such an apparatus; and an article for use with the apparatus, the article including a container defining a cavity, and a mass of smokable material in the cavity; wherein the apparatus includes a heating zone for receiving at least a portion of the article, and a magnetic field generator for generating a varying magnetic field to be used in heating the smokable material when the portion of the article is in the heating zone. In the system, the container is malleable, or a portion of the container is porous for permitting volatilised material generated by heating the smokable material within the cavity to leave the cavity.

First claim

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 malleable container defining a cavity; a mass of smokable material in the cavity; and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material.

2 . The article of claim 1 , wherein the container comprises a sachet.

3 . The article of claim 1 , wherein the container defines an exterior of the article.

4 . The article of claim 1 , wherein the heating material is in the cavity.

5 . The article of claim 4 , wherein the heating material is within the mass of smokable material.

6 . The article of claim 4 , comprising a material that comprises a mixture of the smokable material and the heating material.

7 . The article of claim 6 , wherein the mixture comprises a mixture of the smokable material and elements, wherein each of the elements comprises heating material that is heatable by penetration with a varying magnetic field.

8 . The article of claim 1 , wherein the container is free of heating material that is heatable by penetration with a varying magnetic field to heat the smokable material.

9 . The article of claim 1 , wherein the container comprises the heating material.

10 . The article of claim 9 , wherein the container comprises a closed circuit of heating material that is heatable by penetration with a varying magnetic field.

11 . The article of claim 9 , wherein the container comprises a mesh that comprises the heating material.

12 . The article of claim 1 , wherein the heating material is in contact with the smokable material.

13 . 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.

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

15 . 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.

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

17 . The article of claim 1 , wherein an exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and the width, wherein the length is greater than or equal to the width, and wherein the width is greater than the depth.

18 . 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 container defining a cavity; a mass of smokable material in the cavity; and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material; wherein at least a portion of the container is porous for permitting volatilized material generated by heating the smokable material within the cavity to leave the cavity.

19 . A system, comprising:
an apparatus for heating smokable material to volatilize at least one component of the smokable material; and an article for use with the apparatus, the article comprising a container defining a cavity, and a mass of smokable material in the cavity; wherein the apparatus comprises a heating zone for receiving at least a portion of the article, and a magnetic field generator for generating a varying magnetic field to be used in heating the smokable material when the portion of the article is in the heating zone; and wherein the container is malleable, or a portion of the container is porous for permitting volatilized material generated by heating the smokable material within the cavity to leave the cavity.

20 . The system of claim 19 , wherein the article comprises heating material that is heatable by penetration with the varying magnetic field to heat the smokable material when the portion of the article is in the heating zone.
