There is provided an aerosol-generating system (10) comprising an aerosol-generating device (12) and a cartridge assembly (14). The aerosol-generating device (12) comprises a device inner housing (18) defining a device cavity (20), an electrical heater (22),and a device outer housing (16). The cartridge assembly (14) comprises a cartridge assembly inner housing (32) defining a substrate compartment (34, 36), an aerosol-forming substrate (38, 40) positioned within the substrate compartment (34, 36),and a cartridge assembly outer housing (28). A portion of the cartridge assembly inner housing (32) is configured to be received within the device cavity (20). When the portion of the cartridge assembly inner housing (32) is received within the device cavity (20), at least a first part of a downstream edge of the device outer housing(16)abuts at least a first part of an upstream edge of the cartridge assembly outer housing (28) so that the cartridge assembly outer housing (28) and the device outer housing (16) form a system outer housing (17). |
