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, an aerosol forming substance within a heat conductive container, an outer member surrounding the heat conductive container, and a mouthend piece. 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 is in a heat exchange relationship with the fuel element, aerosol is thereby formed within the container and passed to the mouth of the user.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
