Abstract

Claims (25)

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

a body of the smokable material; and

an assembly comprising:

a cooling segment for cooling the volatilized at least one component of the smokable material, wherein the cooling segment is a hollow tube defining an air gap within the cooling segment, wherein the cooling segment is adjacent to the body of the smokable material, and wherein the cooling segment is configured to provide a temperature differential of at least 40° C. between a heated volatilized component at a first end of the cooling segment and the heated volatilized component at the second end of the cooling segment, wherein the cooling segment is made of paper, wherein a ventilation region is provided in the hollow tube to enable air to pass into the cooling segment, wherein the ventilation region comprises one or more rows of holes formed through the wall of the hollow tube, wherein a ratio of the air to the sum of the heated volatilized components and the air is at least 15%; and

a mouth end segment for being received in a mouth of a user;

wherein the ventilation region is at least 11 mm from a proximal end of the mouth end segment wherein the cooling segment of the smoking article is partially inserted into the heating apparatus when the smoking article is fully inserted into the heating apparatus and wherein there is a portion of the cooling segment that extends out of the heating apparatus when the smoking article is fully inserted into the heating apparatus; and wherein the ventilation holes are located in the portion of the cooling segment that extends out of the heating apparatus.

2. The smoking article according to claim 1 , wherein the cooling segment comprises a spirally wound paper tube.

3. The smoking article according to claim 1 , wherein the cooling segment is configured to provide a temperature differential of at least 60 degrees Celsius between a heated volatilized component entering the first end of the cooling segment and a heated volatilized component exiting the second end of the cooling segment.

4. The smoking article according to claim 1 , wherein the mouth end segment is between 6 mm to 10 mm in length.

5. The smoking article according to claim 1 , wherein the filter segment comprises a mono-acetate material and is of a length between 6 mm to 10 mm.

6. The smoking article according to claim 1 , wherein a length of the assembly is between 37 mm and 45 mm.

7. The smoking article according to claim 1 , wherein the body of smokable material is between 34 mm and 50 mm in length.

8. The smoking article according to claim 1 , wherein each of the one or more rows of holes is arranged circumferentially around the wall of the hollow tube.

9. The smoking article according to claim 1 , wherein the ventilation region comprises a plurality of the rows of holes formed through the wall of the hollow tube, and wherein the rows of holes are axially spaced apart from one another along the ventilation region.

10. The smoking article according to claim 1 , wherein at least one of the holes has a diameter of between 100 μm to 500 μm.

11. A system comprising:

a heating apparatus arranged to heat smokable material of a smoking article to volatilize at least one component of the smokable material, the heating apparatus comprising:

a housing having a first opening at a first end through which the smoking article can be inserted into the heating apparatus, and

at least one heater arrangement arranged within the housing for heating the smokable material of the smoking article when in use; and

a smoking article for insertion into the heating apparatus, the smoking article comprising:

a body of smokable material; and

an assembly comprising:

a cooling segment for cooling the volatilized at least one component of the smokable material, wherein the cooling segment is a hollow tube defining an air gap, wherein the cooling segment is adjacent to the body of smokable material and wherein the cooling segment is configured to provide a temperature differential of at least 40° C. between a heated volatilized component at a first end of the cooling segment and the heated volatilized component exiting at a second end of the cooling segment, wherein the cooling segment is made of paper; wherein a ventilation region is provided in the hollow tube to enable air to pass into the cooling segment, wherein the ventilation region comprises one or more rows of holes formed through the wall of the hollow tube, wherein a ratio of the air to the sum of the heated volatilized components and the air is at least 15%; and

a mouth end segment for being received in a mouth of a user; wherein the ventilation region is at least 11 mm from a proximal end of the mouth end segment wherein the cooling segment of the smoking article is partially inserted into the heating apparatus when the smoking article is fully inserted into the heating apparatus and wherein there is a portion of the cooling segment that extends out of the heating apparatus when the smoking article is fully inserted into the heating apparatus; and wherein the ventilation holes are located in the portion of the cooling segment that extends out of the heating apparatus.

12. A smoking article according to claim 1 , wherein said assembly comprises a filter segment adjacent to the cooling segment for filtering the volatilized at least one component of the smokable material.
