WITH

FIELD OF THE INVENTION This invention relates to hovering articles that create substantially invisible side smoke. More specifically, the invention relates to a smoking article in which the sensations associated with smoking tobacco are achieved without burning tobacco.

i The aim of the invention is to provide

a smoking article in which a material emitting a scented aerosib is effectively heated by the hot gases generated by the passage of air through a carbon heat source and f by thermal radiation from this source. Another object of the invention is to prevent smokers from breathing in such a fiberglass article.

I A further object of the invention is to provide an article which

It looks and feels like a regular cigarette.

In accordance with the invention, a smoking article is provided having a mouthpiece end and a distal end separated from the mouthpiece. The smoking article includes an active element at the distal end in communication with the mouth end, and may also include a filter located in the region of the mouth end. The active element includes a TerwooTpaxafenbHyio no substantially cylindrical hollow sleeve having an inner and an outer wall, and also having a first end at a distal end of the article and a second end located closer to the mouthpiece end of the article. At least a portion of the sleeve near the first end is metallic. In the area of the first end of the sleeve, a heat source is placed.

s o about s

with

The heat source is preferably placed near the first end of the sleeve and at some distance from the inner tube of the sleeve, forming an annular channel around the heat source. The heat source has a through passage for the passage of fluid. An aromatic layer is placed in the region of the second end of the sleeve, which is in heat transfer due to radiation and convection with a heat source. The intermediate element provides a certain interval between the aromatic layer and the heat source. The sleeve in the area near the heat source is breathable, which provides an air inlet to maintain the combustion of the heat source, and is impermeable to air in the area near the aromatic layer, thereby preventing combustion of the material in the aromatic layer. After the heat source is ignited and air is drawn through the torsion product, the air is heated as it passes through the fluid channel. The heated air, passing through the aromatic layer, releases the flavored aerosol from this layer and carries it to the mouthpiece end.

In FIG. 1-8 show a first preferred embodiment of a smoking article according to the present invention. The smoking article 10 consists of an active element 11 and a pipe 12 with an expansion chamber, wrapped in cigarette wrapping paper 14, and

0 of the filter element 13, covered with cigarette paper 205. The wrapping paper 14 is preferably cigarette paper, which is processed so that it undergoes a minimum thermal degradation, for example, paper filled with magnesium hydroxide, or another suitable refractory type cigarette paper, or paper treated with a reversible alumina gel.

0 Considered in more detail below, the active element 11 includes a heat source 20 and an aromatic layer 21 emitting flavored vapors and gases in contact with hot gases 5 passing through the heat source. The vapors pass into a tube 12 with an expansion chamber, forming an aerosol directed to the mouthpiece element 13, and from there into the smoker's mouth.

0 As described in more detail, in pending U.S. Patent Application No. 07 / 223.232, filed July 22, 1988 and referenced herein, the heat source may consist of substantially pure carbon, and preferably carbon with some catalysts or burning additives. The heat source 20 can be formed from charcoal, and

0 it has one or more through channels. These longitudinal channels may be in the form of a multi-pointed star having long tapering ends and a small inner circumference. Volume

The 5 pores of the heat source 20 are more than 517% with a pore size between charcoal particles of about 1 to 2 microns. The heat source 20 may have a weight of about 81 mg / 10 mm and a density of about 0.2 g / cc - 1.5 g / cc. The intermediate surface area of the charcoal particles used) in the heat source 20 may be about 50-2000 m2 / g.

| Aromatic layer 21 may include any material in Eb; emitting the desired aromatic odors and other substances in contact with hot gases. In a smoking article, there may be both tobacco related and other desirable aromatic substances. For example, tobacco filler or backing material on which the desired compounds are applied may be suitable materials for aromatic layer 21. In a preferred embodiment, described in detail in simultaneously examined application No. 07 / 222.831, dated July 22, 1988, and presented in this application in its entirety as reference material, aromatic Soy 21 is a printed tablet tobacco. The tablets are preferably formed by combining in a extruder particles of tobacco particles of particles of about 20 to about 400 mesh, and more preferably about 150 mesh, the starting material is aerosol, for example glycerol, 1,3-butanediol or propylene glycol or mixtures thereof, which can be widely distributed between tobacco particles, and finely divided filler material, for example, calcium carbonate or alumina, used to increase the heat load limit so that hot gases cannot heat tablets to a temperature that exceeds the temperature of their destruction and exposure to heat. The materials are blended to form a mixture that is squeezed through an extrusion die with a plurality of outlet openings to produce spaghetti-like filaments of approximately the same Diameter. The extruded strands are cut into pieces of preferably the same length. The tablets are preferably uniform in size and contain a mixture of about 15-95% tobacco, 5-35% aerosol-forming intermediate and 0-50% excipient, | When a sufficient amount of oxygen is supplied, as discussed in more detail below, the heat source will burn, forming in most cases carbon dioxide. As also indicated below, the bushing 22 of the active element 11 that reflects the energy of thermal radiation is practically non-flammable and does not burn when smoking the product 10. In addition, the product 10 is designed such that gases passing through the aromatic layer 21 have a reduced oxygen content, which is also discussed below, as a result of which the constituents of the aromatic words 21 undergo pyrolysis and do not burn, even if their temperature 5 is high enough to burn them under other conditions. When smoking product 10, the lateral smoke fraction is practically invisible.

Turning to the structural details of product 10, we see that the active element 11 is placed in a composite sleeve including a sleeve 11 reflecting the radiation energy and preferably an internal sleeve 23 placed inside the sleeve reflecting the radiation energy of the sleeve 22. (Hereinafter in the text of the description, unless specifically defined, the term sleeve means a composite sleeve). The inner sleeve 23 is bent and forms a bent chrome .0 cu 24, which supports the carbon heat source 20 at some distance from the inner wall of the energy-reflecting radiation of the sleeve 22, forming an annular space 25, Aromatic layer

5 21 are located in the inner sleeve 23 between the bent edge 24 and the heat source 20 at one end and a grid-shaped holder or cap 26 holding the granules of the layer 21, but at the same time

0 aerosol pass into the tube 12c with an expansion chamber at the other end. Tube 12 with an expansion chamber lengthens the article 10, giving it the appearance of a conventional cigarette. Mouthpiece Part 120

5 of the inner sleeve 23 extends beyond the mouthpiece part; reflecting the thermal energy of the sleeve 22 and enters the tube 12 with an expansion chamber. The wrapping paper 14 holds together the active element 14 and the tube 12 with the expansion chamber. Preferably, the cigarette paper 14 has sufficient porosity, allowing air to pass through the paper 14, and reflecting thermal

5, energizing sleeve 22 to maintain combustion of heat source 20.

In another embodiment, the paper 14 can be perforated, for example, by electrostatic or laser perforation in the area of the heat-reflecting sleeve 22 surrounding the heat source 20.

Preferably seated in the inner sleeve 23 after the holder 26

5, an aluminum liner 27 seals the mouthpiece end of the active element 11, leaving only an opening 28 for the passage of hot vapors. The channel in the through hole 28 causes an increase in the speed of the hot

vapor, and then their expansion when entering the expansion chamber of the tube 12. During expansion of vapors and gases in the expansion chamber, saturated vapors are cooled and stable aerosols are formed, thereby minimizing condensation on each mouthpiece segment 29, 200 and increasing the level aerosol delivery to a smoker. The degree of expansion and therefore cooling can be controlled by selecting the size of the through hole 28 and the volume of the expansion chamber 12.

The mouthpiece element 13 may be a hollow tube or may include a filter segment 29. The mouthpiece element 13 preferably includes two segments 29, 200. The mouthpiece segment 29 is an acetate filter tube 201 wrapped in paper 202. Segment 200 is a core of tobacco filler or other tobacco-containing material wrapped in a wrapper 203 for cork, which, in addition to cooling the aerosol and performing some filtering, can add tion taste of tobacco. The tobacco filler placed in segment 200 is preferably cut into 30 standard cuts per inch, although grinding may be coarser in order to minimize filtration. For example, a tobacco filler may be cut into about 15 cuts per inch. Both segments 29, 200 of the mouthpiece element 13 are jointly wrapped with a wrapper 204, and the entire mouthpiece element 13 is connected to the rest of the product 10 with a mouthpiece wrapper 205. In another embodiment, the segment 20 may consist of another material or may be absent altogether.

Considering the design of the active element 11, we see that the annular space 25 provides a sufficient amount of air to the heat source 20 and stable combustion of the latter, while the heat transfer to the outside is minimal. For this, the heat-reflecting sleeve 22 is perforated, and it preferably has at least about 9.5% open area and a permeability of about 9.1-15.1 measured as follows:

The permeability testing device 90 shown in FIG. 9. they are assembled from tubular sections 91, 92, 93, 94 having the same diameter as the sleeve 22 reflecting thermal energy, which is connected to the device 90. Various nitrogen gas is pumped into the hole 95 at a speed of 2 liters per minute. Hole 96 is open to the atmosphere. Gas is pumped through hole 97 at a rate of 1 liter per minute. Since the resistance to the flow of air as it passes through the wall of the sleeve 22 is less than when it passes through the tubular channel of the device 90, the air will be drawn inward through the wall of the heat-reflecting sleeve 22 and exit through the opening 97 with some nitrogen gas. At the end of the tubular section 93, below the tubular section 94, a mass spectrometer probe 98 is placed, which is connected by a cable 99 to the mass spectrometer 900. Cable 99 leaves the pipe 94 at point 901. The hole through which the cable 99 passes is hermetically sealed so that oxygen can pass into the device 90 only through the wall of the heat-reflecting sleeve 22. The permeability of the heat-reflecting sleeve 22 is determined by the number of milliliters of oxygen per minute per square cm, the surface area of the sleeve 22 measured by a mass spectrometer probe 98 and 900.

The permeability of the heat-reflecting sleeve 22l determines the mass burning rate of the heat source 20. It is advisable for product 10 to produce about 10 puffs under conditions of ignition temperature (a two-second puff is made with a volume of 35 milliliters per minute). If the mass burning rate of the heat source 20 is sufficiently high, then with each puff produced by the smoker, an additional amount of aroma will be created, since the gases reaching the aromatic layer 21 will be hotter, however, since with each puff more and more if the heat source 20 is consumed, this source can be consumed in less than 10 puffs. Similarly, if the rate of mass burning is too low, more than 10 puffs can be produced, but with each puff, less aromatic smell is created since the gases will be colder. In addition, if the mass burning rate is too low, the heat source 20 may go out before the smoker prepares for the next puff / It has been found that the preferred mass burning rate is 9 mg / min. - 11 mg / min. In order to achieve such a range of mass combustion rates, it is preferable to provide a permeability between about 9.1 and 15.1 as measured by the above method

 The air in the element 11 enters the aromatic layer through the channel in the terina 20 source. It is desirable that the largest possible surface of the heat source 20 is in contact with the air flow so as to minimize the convective heat transfer to the aromatic layer 21, as well as: as complete combustion as possible. For this reason, the channel 206 is not made of a simple circular cross-section, but of a multipath cross-section, for example, the cross section in the form of a multi-pointed star shown in the drawings. The surface area of the channel 206 is preferably greater than the surface area of the source of hepla 20.

In order to minimize the loss of heat radiated by the article 10, all internal surfaces of the active element 11 are given high reflectivity. For example, heat reflective sleeve 22 may be made of metallized paper. But more preferably, as shown in FIG. 7 and 8, it should be made of paper sheet 70 and inner foil sheet 71. The foil layer 71 reflects the heat radiated by the heat source 20, directing it back to the heat source 20, thereby keeping it hot and not allowed cooling it below the ignition temperature; and attenuation. The reflection of heat with its direction back to the active element 11 also means that more heat is transferred to the aromatic layer 21,

The paper layer 70 may be formed by spiral winding a paper strip or other known method of manufacturing tubular paper products. | 0 however, it is preferable that the paper layer | 70 and the foil layer 71 taken together be passed through equipment similar to that used in the manufacture of conventional cigarettes and by which they are rolled into a tube. With such a preferred embodiment, the edges of the paper layer 70 are overlapped and glued to one another. The paper layer 70 is made porous or perforated so that (to provide the required permeability described above. The foil layer 71 is preferably 1 made of aluminum foil with a thickness of 0.0015 inches in which it is punched (holes with protruding edge and which is then rolled between the rollers, aligning the holes and getting almost equal to the perforated foil.Although during calendering, to some extent, the holes are closed, nevertheless, the required permeability is achieved, since aluminum sheet 5 has at least 4% open area, and preferably 9.5%.

Although the foil layer 71 and reflects a significant part of the heat generated by the heat source 20, however, some

the amount of heat can go out. Therefore, the paper used for the layer 70 is modified to give it the ability to not burn when smoking the article 10.

5, the inner sleeve 23 is also reflective and is formed from an outer aluminum layer 80, an inner aluminum layer 82, and an intermediate paper layer 81. The inner sleeve 23

0 are made by coiling two identical paper-foil laminated strips so. so that the paper side faces the paper side, and thus the two paper sides form an intermediate layer 81. The paper layers are preferably high-caliber paper. In a preferred embodiment, the intermediate layer 81 also includes up to three layers

0 paper that can be treated to reduce the degree of thermal degradation, for example, paper filled with magnesium dioxide, or other suitable fire-resistant cigarette paper, or paper treated with a reversible alumina gel wound between paper / foil laminated strips. The inner sleeve 23 is made impervious to air, since oxygen must not be allowed into the aromatic layer 21 so that tobacco cannot burn, which could cause odors and thermal degradation products to be sprayed. Foil layers 80,

5 82 do not allow air to pass through, as well as the reflected heat radiation in the back of the product, ensuring maximum aromatic odor generation. Air, of course, can be kept out of the aromatic layer 21 in other ways, for example, by wrapping the heat-reflecting sleeve 22 with an air-permeable Material (not shown) in the area of the aromatic layer 21.

5 The foil layers 80, 82 should be as thin as possible so that the stumps have a low heat capacity, providing the greatest heat transfer to the aromatic layer 21. but not so thin that overheating of the paper layer 81 is possible.

The inner sleeve 23 is folded inward to form a curved edge 24, which should be wide enough to hold the heat source 20 in place.

Finally, the active element 11 is provided with a reflective end cap 15, which is held by its curved edges in the sleeve 22. The cap 15 has one or more openings 16 through which air passes into the active element 11. The holes 16 are preferably located on the periphery of the cap 15. In a preferred embodiment six openings are provided that are spaced apart from each other by an equal angle, each of which has a diameter equal to 0.080 inches. Cap T5 enhances the reflection of radiation towards the active element 11, as well as a fuse It generates a heat source 20 from falling out of the product 10 if it is in any way loose, cracked or destroyed. This is important given that the heat source 20 smolders at a high temperature between puffs and even more warms up between puffs. The cap 15 also holds ashes, which may be generated when the heat source 20 is burned.

Preferably, the outer diameter of the article 10 is 7.9 mm, i.e. corresponds to the outer diameter of a regular cigarette. The carbon heat source 20 preferably has a diameter of 4.6 mm and a length of 10.1 mm, and the active element 11 preferably has a total length of 26 mm. The length of the mouthpiece element 13 is preferably 21 mm, of which 11 mm is the length of the tobacco rod 200 and 10 mm is the length of the acetate filter 29. The length of the tube 12 with the expansion chamber is preferably 33 mm, and thus the total length of the article 10 is 79 mm, which is comparable to a conventional long-sized cigarette. In preferred embodiments, the curved edge 24 has a width of 2.6 mm.

A second, more preferred embodiment of the smoking article according to the present invention is shown in FIG. 10-13, and you see the views of the second option, which are not shown in FIG. 10-13 are similar to the corresponding images of the first preferred embodiment.

In embodiment 100 of FIG. 10-13, the intermediate element 101 inside the active element 110 holds the granules of the aromatic layer 21 at some distance from the end face of the carbon heat source 20. It has been found that, compared to the embodiment of FIG. 1-8, the inclusion of an intermediate element 101 contributes to even more heating of the aromatic end

the layer near the heat source 20, because the stream of hot gases, drawn through the opening 206, has time to dissipate until reaching the aromatic layer 21, as a result of which it heats more than the end of the aromatic layer. Similarly, the inclusion of the intermediate element 101 prevents the aromatic layer 21 from burning when the smoking article 100 is ignited. In the absence of

5 of the intermediate element 101 flame, tightened 4 through the passage 206 when lit, could cause the aromatic layer 21 to catch fire or flare up, whereas in the presence of the intermediate element 101, all the flames dissipate, colliding with the intermediate element 101. The intermediate element. 101 is preferably a metal, e.g., aluminum, disc, which preferably has

5, a surface treated, for example, blackened, so that it can absorb heat from a heat source 20 and. emit it in the directions of aromatic layer 21.

0 Inclusion of an intermediate element

101 also offers other benefits. This

the element, for example, prevents the extrusion through the passage 206 of small particles from the aromatic layer 21, for example,

5 breakaway pieces of tobacco tablets and the destruction of the front end of the smoking article 100 in the area between the end cap 15 and the heat source 20, or the loss of all contents from the article 100

0, in case there is no end cap 15, In addition, the intermediate element 101 makes it possible to fill the same number of granules into the aromatic layer with different degrees of density depending

5 from the movement of the element 101 closer or further relative to the holder 26. The different degree of packing of the aromatic layer 21 leads to different degrees of resistance of the article 100 to the flow, as well as different

0 flavor characteristics. Finally, the intermediate element 101, which holds the granules of the aromatic layer 21 at some distance from the heat source 20, prevents the migration of aromatic substances from

5 pellets to a heat source 20, where they could undergo pyrolysis and cause volatilization of odors and the formation of thermal degradation products.

The third, still more preferred embodiment of the smoking article

according to the present invention is shown in FIG. 14-21. Whistle in views of the third zeriant that are not shown in Figs. 14-21, are similar to the corresponding images of the second preferred embodiment or the first preferred embodiment if there is no corresponding image of the second preferred embodiment.

In a third preferred embodiment 300, an aluminum liner 27 having a through hole 28 is omitted. Instead, a holder 26 is used that provides the necessary limited flow pass to achieve the expansion effect in the tube 112 with the expansion chamber (the tube 112 with the expansion chamber is preferably longer than the tube 12).

To obtain the desired flow restriction, the appropriate hole size in the holder 26 is selected.

In addition, in the third preferred embodiment 200, the passage channel in the heat source 220 has a different shape. Instead of a cross section in the form of a multi-pointed star, which has channel 206, channel 226 of heat source 220 in a third preferred embodiment has a cross section in the form of a flower, each branch of which resembles a petal. Preferably, there are six branches in channel 22. The presence of a flower-shaped cross-section allows for more efficient or uniform heat transfer compared to the case of a star-shaped cross-section, as well as better heat control, for example, reducing the tendency to ash formation. The heat source 220 itself does not consist of pure carbon, but contains carbon along with metal nitride, as well as the necessary additives, as in previous cases. A particularly preferred metal nitride for heat source 220 is iron nitride.

Such a heat source, as well as its advantages, are described in more detail in U.S. patent application No. 07 / 443.636, filed November 29, 1989, which is incorporated herein by reference in its entirety. One such advantage is the reduction in smoke components, along with carbon dioxide. Another advantage is to achieve a higher combustion temperature.

Finally, in the third preferred embodiment 300, the heat-reflecting metallized paper sleeve 22 and the perforated metal end cap 15 of the active element 11 are replaced in the active element 211 with an integral glass 222. having an end surface 215. The glass 222 is preferably made of taut aluminum . The holes 216 in the end surface 215 are similar to the holes 16 in the end cap 15, except that the end surface 215 is flat, while the end surface 15 is curved. Of course, the drawing technique allows perforations of any desired shape to be created. Holes 216 give the flame, from a match or a lighter) the ability to set fire to the product 300 and at the same time

5, it extends more evenly along the end of the heat source 220. Grooves are made in the cup 222 and its outer diameter is determined by the aluminum layer 270. The grooves 272 are limited by concave zones 271. The outer diameter of the cup 222 is the same as that of the tube 12 with the expansion a camera, therefore, a flat surface is provided for the wrapper 14. Cup inner diameter 222 in groove area

5, 272 is such that the cup 222. fits snugly and securely into the inner sleeve 23.

The cup 222 may have elongated holes 273 or 274, or both

; . air admission to maintain the burning of the heat source 220. In the preferred embodiment, all the elongated openings are represented by openings 274. However, openings of a different configuration are possible, with the exception of openings on the outside of sleeve 272 in layer 270. Wrap 14 may be breathable with openings 270, since it is made of or in suitable porous paper, perforations are performed in the areas above the holes 274, 273, as described above. However, the wrapper 14 may also have low permeability, since the grooves 272 form air channels leading to the front end of the article 300, providing entry into the holes

5,274 sufficient air to support the combustion and static combustion of the heat source 220.

The use of a metal cup 222 instead of a metal sleeve 22 eliminates the need for paper; layer 70. In addition, due to the fact that the cup 222 has a larger heat capacity, it can function as a heat sink when

5, the user attempts to reignite the article 300 without realizing that it has already been set on fire. In the case of products 10 and 100, an attempt to reignite may result in burning of the wrapper 14. THIS; ALSO RELEVANT TO A Cigarette. However, the likelihood of such a fire in the product 300 is reduced due to the absence of the paper layer 70 and because the cup 222 has a higher heat dissipation capacity than the sleeve 22. In addition, since the metal expands when heated, when the product 300 is used, the degree of contact of the cup 222 with inner sleeve 23 is reduced. Consequently, the sleeve 23 heats up less and therefore the probability of ignition of the wrapper 14 is less.

Thus, it follows from the foregoing that a smoking article is proposed in which a flavored aerosol-emitting material is effectively heated by a carbon or partial carbon heat source, which eliminates the possibility of smokers breathing glass fiber, which minimizes the loss of heat reaching the walls of the aromatic layer, and which It looks and feels like a regular cigarette. One skilled in the art will appreciate that the present invention can be embodied not only in the embodiments described above, but in others, and the presented embodiments are illustrated as an example embodiment of the invention, which is limited only by the claims set forth below.
