EP0277519A3 — Aerosol delivery article

USPTO Abstract

An aerosol delivery article is capable of producing substantial quantities of smoke, both initially and over the useful lifetime of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream smoke. The article also delivers very low levels of carbon monoxide. The article is able of providing the user with the sensations and benefits of cigarette smoking without burning tobacco. The article includes a carbonaceous fuel element (18), an aerosol forming substance within a heat conductive container (26,36), an outer member (14) surrounding the heat conductive container, and a mouthend piece (24). Upon draw on the mouthend piece air enters the peripheral region of the outer member and enters the heat conductive container. As the heat conductive container (26) is in a heat exchange relationship with the fuel element (18), aerosol is thereby formed within the container and passed to the mouth of the user.
