US 4,819,665 A · Aerosol delivery article

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.

Dependent claims

A cigarette-type aerosol delivery article comprising:

(a) a carbonaceous, combustible fuel element having a length of less than about 30 mm prior to use;
(b) aerosol generating means physically separate from the fuel element and including at least one aerosol forming substance;
(c) barrier means physically separate from the fuel element, and positioned between the fuel element and the aerosol generating means for substantially precluding combustion gases from the fuel element from passing directly through the article;
and
(d) means for providing a source of air to the aerosol generating means through the periphery of the article.
