Heat insulated apparatus for heating smokable material

1. An apparatus comprising:

a smokeable material heating chamber constructed and arranged to removably receive smokeable material that is insertable by a user into the smokeable material heating chamber and that is removable from the smokeable material heating chamber by the user after use;

an electrical heater configured to heat smokeable material received in use in the smokeable material heating chamber to volatilize at least one component of the smokeable material;

a controller configured to control activation of the electrical heater; and

a region of insulation having a closed core that is evacuated to a lower pressure than an exterior of the region of insulation, the region of insulation being located between the electrical heater and an exterior of the apparatus such that the electrical heater is outside of the closed core so as to reduce heat loss from the apparatus.

2. The apparatus of claim 1 , further comprising an energy source electrically coupled with the electrical heater and the controller.

3. The apparatus of claim 2 , wherein the energy source and at least one of the smokeable material heating chamber or the electrical heater are axially aligned.

4. The apparatus of claim 2 , further comprising a housing, wherein the smokeable material heating chamber, the electrical heater, and the energy source are contained within the housing.

5. The apparatus of claim 1 , wherein the region of insulation is located co-axially around the heating chamber.

6. The apparatus of claim 1 , wherein the smokeable material heating chamber comprises a substantially tubular heating chamber and the insulation is located around a longitudinal surface of the tubular heating chamber.

7. The apparatus of claim 6 , wherein the insulation comprises a substantially tubular body of insulation located around the heating chamber.

8. The apparatus of claim 1 , wherein the smokeable material heating chamber is located between the insulation and the heater.

9. The apparatus of claim 1 , wherein the heater is located between the smokeable material heating chamber and the insulation.

10. The apparatus of claim 9 , wherein the heater is located co-axially around the heating chamber and the insulation is located co-axially around the heater.

11. The apparatus according to claim 1 , wherein the closed core comprises a deep vacuum.

12. The apparatus of claim 11 , wherein the vacuum is a hyper deep vacuum.

13. The apparatus of claim 1 , wherein the region of insulation comprises an exterior wall which encloses the closed core, wherein the exterior wall comprises a layer of stainless steel having a thickness of at least approximately 100 microns.

14. The apparatus of claim 1 , wherein wall sections of the exterior wall on either side of the closed core converge in an end region of the region of insulation.

15. The apparatus of claim 1 , wherein a thickness of the region of insulation is less than approximately 1 mm.

16. The apparatus of claim 1 , wherein a heat transfer coefficient of the region of insulation is between approximately 1.10 W/(m 2 K) and approximately 1.40 W/(m 2 K) when a temperature of the region of insulation is in a range of from 100 degrees Celsius to 250 degrees Celsius.

17. The apparatus of claim 1 , wherein the apparatus is configured to heat the smokeable material without combusting the smokeable material.

18. An apparatus configured to heat smokeable material to volatilize at least one component of the smokeable material, comprising:

a smokeable material heating chamber constructed and arranged to removably receive smokeable material that is insertable by a user into the smokeable material heating chamber and that is removable from the smokeable material heating chamber by the user after use;

a region of insulation having a closed core region that is evacuated to a lower pressure than an exterior of the insulation, and

a wall of the region of insulation that defines the closed core region being uninterrupted and having a coating for absorbing gas in the closed core region, the region of insulation being located between the smokeable material heating chamber and an exterior of the apparatus so as to reduce heat loss from the apparatus.

19. An apparatus configured to heat smokeable material to volatilize at least one component of the smokeable material, comprising:

a region of insulation having a closed core region defined by an uninterrupted exterior wall, the closed core region being evacuated to a lower pressure than an exterior of the insulation; and

a smokeable material heating chamber, the smokeable material heating chamber comprising a substantially tubular heating chamber that is open at a first end and a second end opposite the first end, the smokeable material heating chamber being constructed and arranged to removably receive smokeable material that is insertable by a user into the smokeable material heating chamber and removable from the smokeable material heating chamber by the user after use, the region of insulation being located between the smokeable material heating chamber and an exterior of the apparatus so as to reduce heat loss from the apparatus.

20. The apparatus according to claim 19 , comprising a housing that has at least one air inlet, the at least one air inlet being located upstream of the smokeable material heating chamber such that air can enter the at least one air inlet, enter into the smokeable material heating chamber at the first end, pass through the smokeable material heating chamber and exit the smokeable material heating chamber at the second end.
