Problems solved by technology

Uniformity of flavored cigarettes is not fully satisfactory due to loss of flavoring
In addition, flavorings are absorbed by sorbents in cigarettes, reducing the activity of the sorbents, which in turn reduces their ability to remove gas-phase components of tobacco smoke

Embodiment Construction

[0023] The electrically heated cigarette includes one or more sorbents and at least one flavoring agent for affecting the smell, taste and / or aroma of tobacco smoke. In a preferred embodiment, the flavoring is incorporated into the cigarette in a flavor release additive which preferably reduces the release and / or migration of the flavoring within the tobacco prior to smoking. Preferably, the flavor is released from the flavor release additive in a controlled manner during smoking. The flavor release additive allows the flavor to enhance the subjective characteristics of the cigarette without adversely affecting the effectiveness of the sorbent in removing selected gas phase components from mainstream smoke.

[0024] In a preferred embodiment of an electrically heated cigarette, the flavor releasing additive releases the flavor once heated to at least one minimum temperature (flavor release temperature), which occurs when the smoker draws mainstream smoke through the cigarette....

Abstract

An electrically heated cigarette (23) for an electrical smoking system, comprises at least one sorbent and a flavoring-release additive including at least one flavoring releasable in the electrically heated cigarette upon the flavoring-release additive being heated to at least a minimum temperature. The flavoring-release additive includes at least one flavoring. The flavoring-release additive can have various forms including, for example, beads, films and inclusion complexes. Electrical smoking systems including the electrically heated cigarettes, methods of making the cigarettes, and methods of smoking the cigarettes are also disclosed.

Description

[0001] related application [0002] This application is a continuation-in-part of U.S. No. 10 / 695,760, filed October 30, 2003, which claims benefit under 35 U.S.C § 119, entitled "Electric Heating with Controlled Release of Flavoring Agents" filed October 31, 2002 Cigarettes," the priority of U.S. Provisional Application No. 60 / 422,497, the entire contents of which are hereby incorporated by reference. Background technique [0003] Traditional cigarettes are smoked by lighting one end of a wound tobacco rod and drawing air through the lit end by drawing air through the mouthpiece end of the cigarette. Conventional cigarettes emit smoke resulting from combustion in which tobacco burns at temperatures typically in excess of 800°C in a puff of smoke. The heat of combustion releases various gaseous combustion products and tobacco distillates. As these gaseous products are drawn up by the cigarette, they cool and condense to form aerosols, which provide the flavor and aroma of th...
