Definitions
- the present invention relates to a smoking article having a front end and a rear end and comprising a fuel element having a lighting end, and a physically separate aerosol generating means comprising at least one aerosol forming material and being disposed between the lighting end of the fuel element and said rear end. More particularly, the present invention relates to such a smoking article which produces an aerosol that resembles tobacco smoke, and which contains no more than a minimal amount of incomplete combustion or pyrolysis products.
- US-A-4 340 072 describes a proposed cigarette type smoking article with a rod-like fuel element having a cigarette paper overwrap and a central axial passage, an aerosol generating means defined by a chamber and a short filter tip all of which are arranged one behind another.
- the overall length of the smoking article is 70 mm, and its diameter is 7 mm.
- the fuel element is a moulding or extrusion of reconstituted tobacco and/or tobacco substitute, e. g. of a mixture of carbon and a binder (SCMC), and the front end of its axial passage may be closed by a plug made from the same material and serving the purpose of closing the central axial passage of the fuel element and thereby assisting even lighting of the article.
- SCMC mixture of carbon and a binder
- the chamber of the aerosol generating means contains inhalant material which, when contacted by hot gases produced by the burning fuel element and sucked through its axial passage and through the chamber of the aerosol generating means, purportedly forms an aerosol for inhalation by the smoker.
- the length of the rod-like fuel element is about 73 % of the overall length of the cigaretty type smoking article and therefore about 51 mm.
- EP-A-0 117 355 describes a proposed cigarette type smoking article having a carbon heat source with an axial passageway and a separate flavor generator.
- the heat source (page 2, line 23 to page 7, line 14) is formed by pyrolyzing a preformed, tube-shaped ligno-cellulosic material of e. g. 90 mm or 65 mm length (see Comparative Example 1 and Example 4, respectively) under specified conditions, followed by at least one additional specified process step.
- the purported flavor generator (page 8, lines 8 to 27) comprises a substrate material, which may be tobacco, alumina, etc., adjacent the mouth end, which is impregnated with or inherently contains at least one thermally releasable flavorant.
- the flavor generator also may comprise a flavored, foamed core inside the heat source.
- a conventional filter may be placed after the flavor generator.
- the purported formation of an aerosol during use is described from page 8, line 28 to page 9, line 8.
- the tube-shaped ligno-cellulosic material experiences a maximum dimensional shrinkage of 37,5 % (see page 12, lines 3 and 4) so that from a tube-shaped ligno-cellulosic material with a length of 65 mm a carbon heat source with a length of more than 40 mm is obtained.
- this object is achieved by providing a smoking article as defined at the beginning with a resilient insulating member, surrounding at least a portion of the fuel element and comprising inorganic fibers and being at least 0,5 mm thick, and with an overwrap for the insulating member.
- the inventive smoking article is capable of producing substantial quantities of aerosol, 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, and preferably without substantial quantities of sidestream smoke.
- Smoking articles in accordance with the present invention are capable of providing the user with the sensations and benefits of cigarette smoking, without burning tobacco.
- the fuel element is less than about 30 mm in length, more preferably less than 15 mm in length, has a density of at least 0.5 g/cc, and is provided with one or more longitudinal passages.
- the aerosol generating means includes a heat stable substrate including one or more aerosol forming substances.
- the heat exchange relationship between the fuel and the aerosol generator is achieved by providing a heat conducting member, such as a metal foil, which efficiently conducts or transfers heat from the burning fuel element to the aerosol generating means. This heat conducting member preferably contacts the fuel element and the aerosol generating means around at least a portion of their peripheral surfaces.
- At least a part of the fuel element is provided with a peripheral insulating member, such as a jacket of insulating fibers, the jacket being resilient and at least 0.5 mm thick, which reduces radial heat loss and assists in retaining and directing heat from the fuel element toward the aerosol generating means.
- the insulating member preferably overwraps at least part of the fuel element, and advantageously at least part of the aerosol generating means.
- the hot, burning fire cone is always close to the aerosol generating means, which maximizes heat transfer thereto and maximizes the resultant production of aerosol, especially in embodiments which are provided with a heat conducting member.
- the preferred use of a relatively short, low mass substrate or carrier as the aerosol generating means, in close proximity to the short fuel element, also increases aerosol production by minimizing the heat sink effect of the substrate. Because the aerosol forming substance is physically separate from the fuel element, it is exposed to substantially lower temperatures than are present in the burning fire cone, thereby minimizing the possibility of thermal degradation of the aerosol former.
- the especially preferred use of a carbonaceous fuel element which is substantially free of volatile organic material eliminates the presence of substantial pyrolysis or incomplete combustion products and eliminates the generation of substantial sidestream smoke.
- the smoking article of the present invention normally is provided with a mouthend piece including means, such as a longitudinal passage, for delivering the volatile material produced by the aerosol generating means to the user.
- a mouthend piece including means, such as a longitudinal passage, for delivering the volatile material produced by the aerosol generating means to the user.
- the article has the same overall dimensions as a conventional cigarette, and as a result, the mouthend piece and the aerosol delivery means usually extend over more than half the length of the article.
- the fuel element and the aerosol generating means may be produced without a built-in mouthend piece or aerosol delivery means, for use with a separate, disposable or reusable mouthend piece.
- the smoking article of the present invention also may include a charge or plug of tobacco which may be used to add a tobacco flavor to the aerosol.
- the tobacco is placed at the mouth end of the aerosol generating means, or it may be mixed with the carrier for the aerosol forming substance.
- Flavoring agents also may be incorporated into the article to flavor the aerosol delivered to the user.
- Preferred embodiments of the invention are capable of delivering at least 0.6 mg of aerosol, measured as wet total particulate matter, in the first 3 puffs, when smoked under FTC smoking conditions.
- FTC smoking conditions consist of two seconds of puffing (35 ml total volume) separated by 58 seconds of smolder).
- More preferred embodiments of the invention are capable of delivering 1.5 mg or more of aerosol in the first 3 puffs.
- embodiments of the invention are capable of delivering 3 mg or more of aerosol in the first 3 puffs when smoked under FTC smoking conditions.
- preferred embodiments of the invention deliver an average of at least about 0.8 mg of wet total particulate matter per puff for at least about 6 puffs, preferably at least about 10 puffs, under FTC smoking conditions.
- the smoking article of the present invention also is capable of providing an aerosol which is chemically simple, consisting essentially of oxides of carbon, air, water, and the aerosol which carries any desired flavorants or other desired volatile materials, and trace amounts of other materials.
- the aerosol preferably has no significant mutagenic activity according to the Ames test discussed hereinafter.
- the article may be made virtually ashless so that the user does not have to remove any ash during use.
- aerosol is defined to include vapors, gases, particles, and the like, both visible and invisible, and especially those components perceived by the user to be “smoke-like,” generated by action of the heat from the burning fuel element upon substances contained within the aerosol generating means, or elsewhere in the article.
- aerosol also includes volatile flavoring agents and/or pharmacologically or physiologically active agents, irrespective of whether they produce a visible aerosol.
- conductive heat exchange relationship is defined as a physical arrangement of the aerosol generating means and the fuel element whereby heat is transferred by conduction from the burning fuel element to the aerosol generating means substantially throughout the burning period of the fuel element.
- Conductive heat exchange relationships can be achieved by locating the aerosol generating means in contact with the fuel element and in close proximity to the burning portion of the fuel element, and/or by utilizing a conductive member to carry heat from the burning fuel to the aerosol generating means. Preferably both methods of providing conductive heat transfer are used.
- carbonaceous means primarily comprising carbon
- the term "insulating means" applies to all materials which act primarily as insulators. Preferably, these materials do not burn during use, but they may include slow burning carbons and like materials, as well as materials which fuse during use, such as low temperature grades of glass fibers.
- the insulators have a thermal conductivity in g-cal/(sec) (cm2)(°C/cm) , of less than about 0.05, preferably less than about 0.02, most preferably less than about 0.005. See, Hackh's Chemical Dictionary , 34 (4th ed., 1969) and Lange's Handbook of Chemistry , 10, 272-274 (11th ed., 1973).

- This macrocapsule is preferably positioned entirely within the insulator jacket 86.
- the lighting end 11 of fuel element 10 does not protrude beyond the forward end of jacket 86.
- the macrocapsule and the rear portion of the fuel element are surrounded by a piece of aluminum foil.
- the granular substrate 54 may be a granular, thermally stable carbon.
- the capsule 52 is crimped at its ends to enclose the material 54, 56 and to inhibit migration of the aerosol former.

- a void spaced formed by the front end of the capsule also helps to inhibit migration of the aerosol former to the fuel. Longitudinal passageways are provided in the crimped ends to permit the passage of air and the aerosol forming substance.
- Capsule 52 and fuel element 10 may be united by a conventional cigarette paper, a perforated ceramic paper, or a foil strip. If cigarette paper is used, a strip near the rear end of the fuel element should be printed or treated with sodium silicate or other known materials which cause the paper to extinguish.
