`ABSTRACT
`A simulated smoking device, adapted for non-burning
`or non-combustion uses, comprises: a container defining
`a passageway therethrough; a source of vaporizable
`nicotine in fluid communication; and means for prevent
`ing the evaporation of said nicotine during periods of
`non-use. The source of vaporizable nicotine may be an
`absorbent material which has a nicotine-bearing mate
`rial absorbed therein. The absorbent may also have
`absorbed therein a pH adjustment, water and/or flavor
`ing ingredients. The device, at ambient temperatures
`and pressures, releases nicotine vapors into air drawn
`through the passageway of the container during use.

`BACKGROUND OF THE INVENTION
`This invention relates to non-combustible cigarettes
`designed to reduce or eliminate the disadvantages asso
`ciated with conventional smoking habits using combus
`tible cigarettes.
`The use of nicotine has long been practiced by per
`sons in many cultures, who derive satisfaction from the
`substance. Nicotine is a toxic liquid alkaloid having the
`formula C5H4NCAH7NCH3. When the nicotine is ob
`tained from tobacco, as by chewing, sniffing, or smok
`ing the substance, the amount of nicotine absorbed into
`the body generally does not build up to a harmful dose,
`but produces certain pleasurable effects, frequently
`leading to habitual use.
`One of the most popular versions of nicotine use
`involves the smoking of cigarettes. When the tobacco in
`a conventional cigarette is ignited, the combustion of
`the processed tobacco leaves within the cigarette causes
`25
`the release of vaporous nicotine, which is drawn
`through the cigarette and into the user's mouth and
`lungs when the user sucks or inhales air through the
`cigarette.
`The relative mildness of a cigarette, as compared to a
`30
`pipe or cigar, permits a user to draw the smoke from the
`burning cigarette directly into the lungs. The nicotine
`vapors in the cigarette smoke are rapidly assimilated
`into the bloodstream of the user from the lungs, so that
`cigarette smoking provides a method by which a user
`may very quickly feel the effects of the nicotine.
`Although nicotine can thus be readily introduced into
`the body through cigarette smoking, the combustion of
`the tobacco, with the consequent elevated temperatures
`required in this process, unfortunately result in a num
`40
`ber of undesirable consequences associated with smok
`ing combustible cigarettes. Of primary concern are the
`serious health hazards known to result from smoking
`combustible cigarettes. Although the nicotine content
`of a cigarette is not believed to cause any serious ad
`45
`verse long term health effects on the human body, many
`other components which are harmful are present in
`tobacco smoke. Some of these other constituents are
`known carcinogens, for example. A table listing some of
`the harmful components in tobacco smoke may be
`50
`found on pp. 496-501 of the publication Tobacco and
`Tobacco Smoke, Studies in Experimental Carcinogene
`sis (1967) by Ernest L. Wynder and Dietrich Hoffman
`of the Sloan-Kettering Institute for Cancer Research.
`The teaching of that publication is hereby incorporated
`by reference into this application. Furthermore, the
`smoking of combustible cigarettes may pose a signifi
`cant fire hazard. Many fires which have occurred both
`within buildings and in natural environments have been
`attributable to burning cigarettes which were carelessly
`discarded. In addition, substantial economic losses can
`be attributed to smoking, including significant damage
`to business and personal property resulting from burns
`in clothing, carpeting, furniture, etc. caused by stray
`ashes from cigarettes. Cigarette smoking has also be
`65
`come increasingly objectionable because of the discon
`fort it may cause to nonsmokers who are exposed to the
`smoke and odor produced by the smoking habit.
`
`4,284,089
`2
`Because of these undesirable side effects of combusti
`ble cigarette smoking, attempts have been made from
`time to time to provide an acceptable substitute for
`combustible cigarette smoking which will eliminate or
`ameliorate the adverse consequences mentioned above.
`Tobacco concentrates, for example, have been pro
`cessed into a tablet form which may be sucked or
`chewed in the mouth of the user, the nicotine being
`absorbed into the user's body through the lining of the
`mouth. Such a tablet, of course, does not provide the
`user with the feel of a cigarette between his or her lips.
`Furthermore, a tablet smoking substitute cannot pro
`vide the user with an opportunity to draw air and va
`pors into the mouth nor inhale that air and vapors into
`the lungs, which is an essential part of the conventional
`smoking habit. These activities constitute an important
`aspect of the psychological and physiological affinity
`which a smoker acquires for the habit. Without an effec
`tive substitute for such smoking activities, a tablet form
`of tobacco is likely not to satisfy the smoker and may
`thus result in a return to combustible cigarette smoking.
`In another approach to providing a substitute for
`smoking, it has been recognized that processed tobacco,
`such as that contained in cigarettes, will release vapors
`even when it is heated to a temperature lower than the
`ignition point of the tobacco. Thus, a smoker might
`draw air through such heated tobacco and thereby
`obtain the vapors which are released in conventional
`smoking without also inhaling the noxious by-products
`of tobacco combustion. Devices manufactured accord
`ing to this technique, however, have sometimes used a
`second isolated portion of tobacco, which is ignited, as
`the source of heat. Although such a device is cham
`bered so that the products of combustion are not di
`rectly inhaled by the user in the act of drawing air
`through such a device, the harmful by-products of com
`bustion are nevertheless released into the air surround
`ing the user. Thus, substantial amounts of the deleteri
`ous combustion by-products may nevertheless be in
`haled by the user and surrounding persons through
`breathing the ambient air. In addition, with such a sub
`stitute device, substantially the same. fire hazards are
`presented as with conventional smoking devices, and
`there remains the potential for burn damage to carpets,
`furniture, clothing, etc. Alternatively, the tobacco in
`this method may be heated by various pyrophorous
`materials, which are mixed together with the tobacco.
`Such materials react with oxygen, alcohol, water, etc.
`and thereby produce sufficient heat to cause the to
`bacco to release vapors. With this technique, however,
`any by-products of the combustion reaction, which
`occurs within the tobacco mix, will also tend to be
`inhaled through the device by the user. Thus, there is
`the danger of adverse health consequences resulting
`whenever any of these by-products are toxic or other
`wise harmful. Furthermore, the structure of such de
`vices tend to be unduly complex, resulting in a rela
`tively high manufacturing cost.
`Various other smoking substitutes have been devel
`oped which include cigarette simulating devices con
`taining various materials which approximate the taste
`and aroma of tobacco or release various other addi
`tional aromatic vapors which are intended to have a
`satisfying effect on the user when those vapors are in
`haled. In one such device, synthetic materials simulat
`ing the taste and aroma of tobacco are micro-encap
`sulated within a cigarette substitute device. The desired
`vapors are released by squeezing or crushing the device,
