Abstract
The aerosol-generating article is has an outlet end, a distal end upstream from the outlet end, and a mid-point located an equal distance between the outlet end and the distal end. The article includes a liquid aerosol-forming substrate contained within a frangible capsule, the frangible capsule being located between the distal end and the mid-point. At least a portion of a liquid retention medium is located between the distal end and the mid-point. The article is configured such that, during use, air is capable of being drawn through the article from the distal end to the outlet end.
Claims17
An aerosol-generating article for use with an electrically-operated aerosol-generating device, the aerosol-generating article being a consumable article, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end, a middle of the aerosol-generating article located an equal distance between the outlet end and the distal end, the article comprising:
- a liquid aerosol-forming substrate in a frangible capsule, the frangible capsule being located between the distal end and the middle;
- and
- a liquid retention medium, at least a portion of the liquid retention medium being between the distal end and the middle,
- wherein the article is configured such that, during use, air is drawn through the article from the distal end to the outlet end if negative pressure is applied on the outlet end.
An aerosol-generating system, comprising:
- an aerosol-generating article, the aerosol-generating article being a consumable article, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end, a middle of the aerosol-generating article located an equal distance between the outlet end and the distal end, the article including,
- a liquid aerosol-forming substrate in a frangible capsule, the frangible capsule being located between the distal end and the middle;
- and
- a liquid retention medium, at least a portion of the liquid retention medium being between the distal end and the middle,
- wherein the article is configured such that, during use, air is drawn through the article from the distal end to the outlet end if negative pressure is applied on the outlet end;
- and
- an electrically-operated aerosol-generating device, the electrically-operated aerosol-generating device including a heating structure for heating the aerosol-forming substrate to form an aerosol.
A method of using an aerosol-generating article, the aerosol-generating article for use with an electrically-operated aerosol-generating device, the aerosol-generating article being a consumable article, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end, a middle of the aerosol-generating article located an equal distance between the outlet end and the distal end, the article including a liquid aerosol-forming substrate in a frangible capsule, the frangible capsule being located between the distal end and the middle, and a liquid retention medium, at least a portion of the liquid retention medium being between the distal end and the middle, the article being configured such that, during use, air is drawn through the article from the distal end to the outlet end if negative pressure is applied on the outlet end, the method comprising:
- releasing the liquid aerosol-forming substrate from the frangible capsule so that the liquid aerosol-forming substrate is retained by the liquid retention medium;
- coupling the aerosol-generating article to an electrically-operated aerosol-generating device;
- activating a heating structure of the electrically-operated aerosol-generating device;
- and
- drawing air through the aerosol-generating article in order to cause the liquid aerosol-forming substrate to be vaporized by heat energy supplied by the heating structure and condensed to form an aerosol entrained in the air.
