Article for use in an apparatus for heating smokable material

A system comprising:

• a heating apparatus arranged to heat smokable material 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 a smoking article comprising the smokable material 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 the smokable material, and
• an assembly joined to the body of smokable material by annular tipping paper located around the circumference of the filter assembly to surround the filter assembly and which extends partially along the length of the body of smokable material,
• wherein the assembly comprises:
• a cooling segment which is an annular tube made of paper, said annular tube having first and second opposite end faces, said annular tube defining a chamber for the flow of the at least one volatilized component of the smokable material and for cooling the at least one volatilized component of the smokable material,
• a filter segment adjacent to the cooling segment for filtering the at least one volatilized component of the smokable material, the filter segment comprising filtration material, and
• a mouth end segment adjacent to the filter segment for being received in a mouth of a user,
• wherein the annular tube of the cooling segment is located between the body of the smokable material and the filter segment such that the first end face of the annular tube of the cooling segment is in abutting relationship with the smokeable material, and wherein the filter segment is located between the annular tube of the cooling segment and the mouth end segment and so that the second end face of the annular tube of the cooling segment is in abutting relationship with the filtration material of the filter segment which separates the annular tube of the cooling segment from the mouth end segment, wherein the annular tube of the cooling segment comprises a ventilation region comprising one or more rows of holes formed through the annular tube, each of the one or more rows of holes being arranged circumferentially around the annular tube to enable air to pass into the chamber within the annular tube of the cooling segment to mix with the at least one volatilized component of the smokable material, wherein the at least one heater arrangement is in the form of a hollow cylindrical tube having a hollow interior heating chamber into which the smoking article is inserted for heating during use, and
• wherein the smoking article is arranged so that when the smoking article is fully inserted into the first opening in the housing of the heating apparatus for heating the smokable material, the body of the smokable material is entirely received within the heater arrangement, a first section of the annular tube of the cooling segment is within the housing of the heating apparatus between the heater arrangement and the first opening and a second section of the annular tube of the cooling segment extends from the first opening out of the housing of the heating apparatus, wherein the first section of the cooling segment that is within the housing of the heating apparatus between the heater arrangement and the first opening comprises the majority of the cooling segment.
