Abstract: An aerosol-generating article is provided, including: a rod of aerosol-generating substrate; and a ventilation zone including perforations and being arranged downstream of the rod, the perforations being arranged in a peripheral wall of the ventilation zone, each perforation having a central axis, the aerosol-generating article having a central axis, a smallest distance between the central axis of each perforation and the central axis of the aerosol-generating article being between 3% and 15% of an outer diameter of the aerosol-generating article, a thickness of the peripheral wall of the ventilation zone being between 0.1 millimeter and 2.5 millimeters, and the aerosol-generating article having a ventilation level of at least 20%. An aerosol-generating system including an aerosol-generating device having a cavity configured to receive the aerosol-generating article is also provided. A method for manufacturing an aerosol-generating article is also provided.

Abstract: An aerosol-generating article is provided, including: a rod of aerosol-generating substrate; and a ventilation zone arranged downstream the rod, the ventilation zone being configured as a hollow tubular ventilation zone and including perforations, one or more of the perforations has a non-circular cross-section having an ovality of at least 1.5, the ovality being a ratio of a large diameter of a perforation divided by a small diameter of the perforation, a thickness of a peripheral wall of the ventilation zone being between 0.1 millimeter and 2.5 millimeters, the one or more perforations having a width of between 0.05 millimeter and 0.2 millimeter, and the one or more perforations having a length of between 0.25 millimeter and 1.0 millimeter. An aerosol-generating system including an aerosol-generating device having a cavity configured to receive the aerosol-generating article is also provided. A method for manufacturing the aerosol-generating article is also provided.

Abstract: An aerosol-generating article is provided for producing an inhalable aerosol upon heating, the article including: a mouthpiece assembly including first, second, and third tubes; and an aerosol-forming substrate, in which the first tube abuts a downstream end face of the second tube, and the third tube abuts an upstream end face of the second tube, an internal diameter of the second tube is smaller than an internal diameter of the first tube and of the third tube, the internal diameter of the first tube is between 3 mm and 8 mm, a ratio of the internal diameter of the first tube to the internal diameter of the second tube is between 1.2 and 5, a ratio of the internal diameter of the first tube to the internal diameter of the third tube is between 0.5 and 2, and the second tube is a cellulose acetate tube.
