Abstract:

A heat capacitor for a capillary aerosol generator comprises a phase change material that changes phases at a temperature approximately equal to a temperature sufficient to volatilize liquid material in a capillary passage of the capillary aerosol generator. The phase change material stores heat, which can be used to generate aerosol either continuously or intermittently over a given time. The use of stored heat in the phase change material to generate aerosol over time enables operation of the capillary aerosol generator remote from a large energy source.

International Classification:

A24B 15/30

US Classification:

131276, 131335, 131191, 131337, 131352

Abstract:

Cigarettes are provided which contain a filtering system and flavorants encapsulated with polyvinyl acetate, wherein deactivation of a sorbent by the flavorant is reduced through the encapsulation of the flavorant within the polyvinyl acetate. A preferred flavorant is menthol. The encapsulated flavorants are prepared by mixing at least one flavorant with polyvinyl acetate and a solvent, such as ethanol, and forming the encapsulated flavorants. Methods of making cigarettes and smoking the articles are also provided.

International Classification:

A24B 15/24

US Classification:

131298000, 131297000

Abstract:

A method of forming a liquor comprising tobacco solutes, the method comprising extracting tobacco solutes from tobacco by flowing an extraction solvent through tobacco to form a tobacco solutes-rich extraction solvent and a tobacco solutes-poor tobacco, and forming tobacco solutes-rich liquor by flowing the tobacco solutes-rich extraction solvent through an entrapment solvent, wherein the tobacco solutes comprise nicotine and at least one tobacco flavor compound and/or tobacco aroma compound and the liquor comprises the tobacco solutes dissolved in the entrapment solvent. A preferred extraction solvent comprises a supercritical fluid. Also provided are cigarettes and cigarette components comprising extracted tobacco solutes such as flavor compounds, aroma compounds and nicotine. Further, tobacco from which aroma compounds and/or nicotine have been extracted can be used in cigarettes.

Filed:

May 15, 1996

Appl. No.:

8/648253

Inventors:

Tony M. Howell - Midlothian VA
William R. Sweeney - Richmond VA

Assignee:

Philip Morris Incorporated - New York NY

International Classification:

A61M 500

US Classification:

12820014

Abstract:

An aerosol is formed by supplying a material in liquid form to a tube and heating the tube such that the material volatizes and expands out of an open end of the tube. The volatized material combines with ambient air such that volatized material condenses to form the aerosol. An apparatus for generating such an aerosol, and a method for generating such an aerosol, are also disclosed.

Assignee:

International Classification:

A24B 1524
A24B 1526

US Classification:

131297

Abstract:

A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco without materially affecting the content of the other components of the tobacco. Tobacco is traversed with a solvent at high pressure and in a physical state which is either a liquid at a pressure of from about 500-300 atmospheres or a supercritical fluid wherein nicotine and the other components dissolve in the solvent. As the single means of removing substances from the solvent, the solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine. The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine. In addition, the tobacco may be pretreated with a chemical base which does not substantially react with the tobacco components under ambient conditions and which are not necessarily affected by the process conditions but are nonetheless effective in increasing the amount of nicotine which can be extracted by the process of this invention. Pretreatment of the tobacco with a chemical base neutralizes nicotine salts and permits the extraction process to be carried out under milder conditions.
