摘要:
A heating element to provide heat to a tobacco flavor medium, for use in an electrical smoking article, by converting electrical energy to heat through the use of a material with electrically resistive properties is provided. The material is arranged in a radial array of blades with a current density profile such that a maximum area of each blade provides heat to the tobacco flavor medium dispersed thereon. The blade is generally U-shaped to assure dispersion of heat evenly to avoid hot spots along the blade and is tapered to reduce mass toward the mouth end of the heating element so as to maximize the heated area.

A lighter is provided having a tobacco flavor heating system which includes a rotatable tobacco containing disc or spiral. This disc or spiral is registered in thermal proximity to a heating element and heated to generate tobacco flavors in response to a sensor. The disc and spiral are sized to provide a convenient number of puffs before disposal. Housings are provided for the disc and spiral to store, register and dispose the tobacco product efficiently. An induction heating system can be employed.
摘要:
A smoking article is provided in which a replaceable tobacco flavor unit containing tobacco flavor material is electrically heated by a set of permanent reusable heaters to evolve flavors or other components in vapor or aerosol form for delivery to a smoker. Each heater heats only a portion of the available tobacco flavor material so that a plurality of individual puffs of tobacco flavor substance can be delivered sequentially to the smoker. The replaceable tobacco flavor unit can also include a filter to reduce the effect of residual aerosol which settles or condenses on the permanent portions of the article and which can result in undesirable flavor generation when reheated. A method and apparatus for manufacturing the replaceable tobacco flavor unit is also provided.
摘要:
Thermal indicators for non-combustion smoking articles which physically change when heated to provide visual indications of temperature changes are disclosed. The indicators comprise waxes or other compounds which melt away to reveal colored substrates, or comprise microencapsulated chemicals which are released when heated to cause inking or dyeing. The thermal indicators are printed in variety of patterns along the length of the smoking articles to show temperature changes and to indicate whether the smoking article is finished and should be discarded.

摘要:
An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.
摘要:
Thermal indicators for non-combustion smoking articles which chemically react when heated to provide visual indications of temperature changes are disclosed. The indicators comprise organic acids, sugars, or amines combined with sugars. The indicators are printed in a variety of patterns along the length of the smoking articles to show temperature changes and to indicate whether the smoking article is finished and should be discarded.
