Patent ID: 11832647

Abstract:
There is provided a cartridge (300) for a handheld aerosol-generating system, comprising: a cartridge body (305) comprising an outer wall (325) and an inner airflow tube (320) within the outer body, wherein the inner airflow tube is spaced from the outer wall; and a reservoir (340) of aerosol-forming substrate between the outer wall and the inner airflow tube; wherein the outer wall and inner airflow tube are connected to one another through one or more ribs (326) extending between the outer wall and inner airflow tube, and wherein the outer wall, inner airflow tube and one or more ribs are integrally moulded. With this arrangement a robust cartridge can be inexpensively and reliably manufactured. The ribs provide mechanical support between the outer wall and the inner airflow tube. The integral moulding of the outer wall, inner airflow tube and one or more ribs can ensure or minimise leakage of liquid from the cartridge.
