Abstract
An aerosol-generating article () includes a mouthpiece () comprising at least one segment of filter material () and a liquid delivery element (). The liquid delivery element () comprises: an upstream end and a downstream end; a double-walled annular body portion () comprising: an inner wall () defining a longitudinal channel () extending through the liquid delivery element (); and an outer wall () integrally formed with the inner wall (), the outer wall () circumscribing the inner wall () such that a cavity () is defined between the outer wall () and the inner wall (), the cavity () having an opening in at least one of the upstream end and the downstream end and containing a liquid; and annular sealing means () inserted between the inner wall () and the outer wall () of the annular body portion () to provide a liquid tight seal at the opening or openings of the cavity (). The inner wall () and the outer wall () of the annular body portion () are configured such that the inner wall () is breakable upon application of a compressive force to the liquid delivery element () in a transverse direction and such that upon breakage of the inner wall () the liquid is released from the cavity () into the longitudinal channel ().
