base comprising a sheet of heat conductive material and having a first outer surface; and aerosol generating material located within the first chamber; wherein at least a major portion of the first outer surface of the first base is adapted to contact a first heating surface of a heater of the apparatus for heating the aerosol generating material within the first chamber, and wherein the first base is substantially parallel to a longitudinal axis of the first body; wherein the cartridge further comprises: a second body defining a second chamber, wherein the second body comprises a second base comprising a sheet of heat conductive material having a second outer surface; and aerosol generating material located within the second chamber; wherein at least a major portion of the second outer surface of the second base is adapted to contact a second heating surface of the heater of the apparatus, and wherein the second base is substantially parallel to a longitudinal axis of the second body; and wherein the first base and the second base are connected together to enable relative pivotal movement of the first base and the second base so that a user can bring the first outer surface into contact with the first heating surface of the heater and the second outer surface into contact with the second heating surface of the heater. ### Claim 2 (depends on 1) The cartridge

and a second portion at one end of the first portion, wherein the first portion is wider than the second portion. ### Claim 5 (depends on 4) The cartridge according to claim 4, wherein the first cover comprises a third portion at another end of the first portion, wherein the first portion is wider than the third portion. ### Claim 6 (depends on 1) The cartridge according to claim 1, wherein the first base and the second base are connected along a first line of weakening to enable the relative pivotal movement. ### Claim 7 (depends on 6) The cartridge according to claim 6, wherein the first line of weakening is one of a perforated line, a serrated line or a cut line. ### Claim 8 (depends on 1) The cartridge according to claim 1, wherein the first base and the second base are, in a pre-use configuration, connected at respective sides of the first base and the second base that are substantially perpendicular to a longitudinal axis of the cartridge. ### Claim 9 (depends on 8) The cartridge according to claim 8, wherein the second body comprises a second cover attached to the second base, wherein the second cover and the second base define the second chamber, and wherein the first cover and the second cover are, in the pre-use configuration, connected along a second line of weakening which ruptures when the first base and the second base undergo relative pivotable movement, whereby the first cover and the second cover are separated to provide at least one of a volatilized material and an aerosol outlet for the first cover and at least one of a volatilized material and an aerosol outlet for the second cover. ### Claim 10 (depends on 9) The cartridge according to claim 9, wherein the first base comprises a first piercer and the second base comprises a second piercer. ### Claim 11 (depends on 10) The cartridge according to claim 10, wherein the first piercer is for piercing the second base to provide an air inlet for the second chamber and the
