    • The present invention preferably relates to an insulated smoking article which is capable of producing substantial quantities of smoke, both initially and over the useful life 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. Thus, the article of the present invention is able to provide the user with the sensations and benefits of cigarette smoking without burning tobacco. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use.Preferred embodiments of the present smoking article comprise a short i.e., 30 mm or less (prior to smoking), combustible carbonaceous fuel element, a short heat stable, preferably carbonaceous, substrate longitudinally disposed relative to the fuel element bearing an aerosol forming substance, an efficient insulating means surrounding at least a portion of the fuel element and a relatively long mouthend piece. The fuel element, insulator and substrate are arranged in a heat exchange relationship, providing aerosol formation without significant degradation of the aerosol former.
    • 本发明优选地涉及一种绝缘吸烟制品,其能够在产品的初始和超过使用寿命期间产生大量的烟,而没有气溶胶形成剂的显着热降解,并且不存在实质的热解或不完全燃烧产物 或侧流烟雾。 因此,本发明的制品能够为使用者提供没有燃烧烟草的吸烟的感觉和益处。 此外,制品实际上可以无灰尘,使得使用者在使用过程中不必去除任何灰分。 本发明吸烟制品的优选实施方案包括短的,即30mm或更小(吸烟前),可燃碳质燃料元件,相对于燃料元件纵向设置的短热稳定的,优选含碳的基材,其具有气溶胶形成物质, 围绕燃料元件的至少一部分和相对较长的口气部件的有效的绝缘装置。 燃料元件,绝缘体和基底以热交换关系布置,提供气溶胶形成而不会使气溶胶形成剂显着降解。
