Abstract

Disclosed is material for use with apparatus for heating smokable material to volatilize at least one component of the smokable material. The material includes a mixture of smokable material and elements. Each of the elements includes a closed circuit of heating material that is heatable by penetration with a varying magnetic field.

Claims

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

a material including a mixture of the smokable material and a plurality of elements, each element of the plurality of elements comprising magnetic electrically-conductive material, and wherein the elements of the plurality of elements are aligned magnetically with each other within the article.

2. The article of claim 1, wherein each element of the plurality of elements has a central axis that is substantially aligned with a longitudinal axis of the article.

3. The article of claim 1, wherein each element of the plurality of elements is ring-shaped, spherical, is formed from a plurality of discrete strands of magnetic electrically-conductive material, or comprises a non-conductive body carrying a closed circuit of the magnetic electrically-conductive material.

4. The article of claim 1, wherein each element of the plurality of elements comprises a closed circuit of the magnetic electrically-conductive material.

5. A method of manufacturing material for use with an apparatus configured to heat a smokable material to volatilize at least one component of the smokable material, the method comprising:

providing the smokable material; and

mixing a plurality of elements with the smokable material, each of the elements comprising a closed circuit of heating material that is heatable by penetration with a varying magnetic field;

wherein the heating material is a magnetic material, and the method further comprises magnetically aligning the elements with each other.

6. The method of claim 5, wherein each of the elements is ring-shaped, spherical, is formed from a plurality of discrete strands of the heating material, or comprises a body that is free of heating material that is heatable by penetration with a varying magnetic field and that carries the closed circuit of heating material.

7. The method of claim 5, wherein the smokable material comprises at least one of tobacco or one or more humectants.

8. The method of claim 5, wherein the mixing comprises mixing the plurality of elements with the smokable material to provide an even, or substantially even, disbursement of the plurality of elements throughout a material being manufactured.

9. A system, comprising:

an apparatus configured to heat smokable material to volatilize at least one component of the smokable material; and

an article configured for use with the apparatus, the article comprising;

a material including a mixture of smokable material and a plurality of elements, each element of the plurality of elements comprising magnetic electronically-conductive conductive material, and wherein the elements of the plurality of elements are aligned magnetically with each other within the article,

wherein the apparatus comprises a magnetic field generator configured to, in use, generate a varying magnetic field that penetrates the magnetic electrically-conductive material of the plurality of elements.

10. The system of claim 9, wherein the apparatus comprises an interface configured to cooperate with the article, and the magnetic field generator generates the varying magnetic field when the article cooperates with the interface.
