Cigarette and heating unit for use in electric smoking systems

BACKGROUND OF THE INVENTION The present invention relates generally to an electric smoking system, and in particular to a cigarette cooperating with an electric igniter of an electric smoking system, and to a chill unit suitable for use in an electric smoking system. The invention further relates to a method for improving the smoke yield of an electronic lighter operated cigarette, and to a tobacco web and a method for making a tobacco web.

Conventional cigarettes give the smoker a taste and aroma as a result of burning. During combustion, a certain amount of combustible material, particularly tobacco, burns at temperatures that often exceed 800 ° C in a suction. When the mouth end of a cigarette is smoked, heat is passed through a neighboring tobacco mass. During heating, due to insufficient oxidation of the combustible material, various gaseous combustion products and distillates are released from the tobacco. / When these gaseous products are sucked through the cigarette, they cool and condense and form an aerosol that provides the flavors and aromas of smoking.

Conventional cigarettes have various disadvantages.

One of these disadvantages is that the sniffs between sniffs «* ··>

During drinking, a secondary cook is formed, which can disturb non-smokers. Once a cigarette is lit, it must be completely sucked or discarded, A. A traditional cigarette can be re-lit, but is not attractive to the discerning smoker for subjective reasons (smother, smell, odor).

An alternative to the more conventional cigarette is a cigarette in which the combustible material itself does not release tobacco spray. Such tobacco article may comprise a combustible carbonaceous heating element (a heat source located at or near one end of the tobacco article and comprising a bed of tobacco-filled elements adjacent to said heating element. The fuel element is ignited by a match or lighter and when smoked by a smoker. cigarette, the heat generated by the heating element passes from the tobacco-filled elements to the bed, thereby releasing the tobacco spray into the bed.Mud this type of smoking device produces little or no secondary smoke, yet combustion products are produced at the heat source and the source of heat has already been ignited. then it is practically not easy to extinguish it for reuse,

In both the more conventional and the coal-fired appliances described above, combustion occurs during use. Of course, many by-products are formed during this process when the material burned decomposes and interacts with the surrounding atmosphere.

08 / 380,718 (<1697 Con.t) and September 11, 1992; U.S. Patent Application Serial No. 07 / 943.504 (PM 1550 Cont), and U.S. Patent Nos. 5,093,834, 5,225,498, 5,060,671, and 5,095,921 disclose various types of fuel and aroma preparation which significantly reduce secondary and secondary smoke. however, they allow the smoker to quit and restart smoking at will. However, the garnet articles described in these patents are not very durable and may flatten, break, or break when subjected to prolonged or rough treatment. Under certain circumstances, these known cigarettes may crumble because they are weaker and may tear or break when removed from the collector.

A preferred embodiment of the cigarette described in European Patent Application Serial No. 08 / 330,718 (PM 16-97 Cont) and in European Patent Application SP-A0,815,411 is a tobacco-filled tubular carrier, a cigarette paper wrapped around a tubular carrier at the mouth end of the carrier. The filter insert comprises an arrangement and a filter insert at the free (outer) end of the support. The cigarette and collector are configured such that when the cigarette is inserted into the lighter and each individual fuel element.2 is activated each time a localized carbonization occurs at the point where the fuel element contacts the cigarette (these heφ Jfr ♦ Φ * Η

They are hereinafter referred to as the "fuel footprint". When all the fuel elements are actuated, these carbonated points are closely spaced and surround the center portion of the hot section of the cigarette.

Depending on the maximum temperature and the total heat supplied to the heating elements, the carbonized points are not only reflected in the color of the cigarette paper paste. In most applications, the carbonization will at least create tiny tears in the cigarette paper and underlying substrate. These tears mechanically weaken the cigarette. In order for the cigarette to be pulled out of the lighter, the charred points must be slid at least partially through the heating elements. In more complex circumstances, such as when the cigarette is wet, or if the cigarette has been tampered with or twisted, the cigarette may tear or its pieces may remain when pulled out of the collector. Pieces left in the collector may interfere with the collector's proper operation and / or make the next cigarette smoke. If the cigarette breaks when pulled out, the smoker will not only have a problem with the faulty cigarette product, but also have to clean the debris from the clogged lighter before enjoying another cigarette.

In a preferred embodiment of US 08 / 380,718 (Pb 1097 cont.), European Patent Application KP-A-0,615,411 and US 5,388,594, the filter insert on the outer end of the cigarette is substantially on the suction end of the cigarette. It is believed that this design enhances the yield for the smoker by providing sufficient space for the aerosol to enter the carrier with minimal collision and minimal condensation on surrounding surfaces.

Many suggestions have been made to reduce unwanted secondary smoke while allowing the smoker to stop smoking for a desired period of time and then to resume smoking. For example, U.S. Patent Nos. 5,093,894, 5,225,498, 5,06-0,671, and 5,095,921, issued jointly, disclose various heating elements and aroma production systems. European Patent Application EP-A-0,615,411 and US Patent No. 5,338,594 disclose an electric smoking system in which the fuel elements are actuated by a control and logic circuit when a suction is detected. Preferably, the heating elements are configured in a relatively thin snake shape to supply a sufficient amount of heat to the cigarette. The heating elements are lightweight.

While these apparatuses and heating elements overcome the observed problems and fulfill the intended purposes, many embodiments are subject to mechanical weakening and possibly malfunction due to the stresses caused by the insertion and removal of the rolled tobacco and the alignment or grooving of the inserted cigarette.

V

In addition, undesirable electrical short-circuits may occur if the shape of the grass assembly is altered, for example, by aligning or weaving the inserted cigarette.

In electric tramlining systems, heating elements with electric resistance are also suitable. Chairs require relatively elaborate electrical connections that can be interrupted by inserting and removing the cigarette.

When a filler cut into the hollow structure of a cigarette according to European Patent Application EP-A-0,615,411 was filled, it was found that such cigarettes, fully filled with cut tobacco filler, functioned properly in the first few snacks. Thereafter the yield decreased. The same phenomenon occurred when more conventional cigarettes were used in an electric lighter, so that the hollow olgarette structure of the EP-A0,615,411 lighter was omitted. were subjected to some degree of collapse in extreme or coarse treatment.

Thus, another preferred heating arrangement is described in U.S. Patent Application Serial No. 08 / 224,348 {9 -1729B}, filed April 3, 1991, which is hereby incorporated by reference.

Referring now to FIG. 2, it can be seen that the control circuit 41 is preferably activated by a sensor 45 which is activated by a sniffer. The sensor 45 detects either pressure changes or changes in air flow that occur when the smoker smokes the cigarette 23. Preferably, the sniffer sensor 45 is located at the front 33 of the lighter housing 25 and is connected to a space within the fuel compartment 39 near the cigarette 23 through a channel that is spaced at the bottom of the fuel compartment 33 and, if desired, - goes through a sniffing tube. The sniffer sensor 45 for use in the smoking system 21 is described in U.S. Patent No. 5,060,671 (P55 1337}. Preferably, the sniffer sensor 45 is manufactured by MicroSwitch Division of Honeyweol, Inc., Freeport, Illinois, USA. Silicon sensor 163PC01D35.

Flow sensing devices, such as sensors based on the thermo-anemometric principle, have also been shown to be capable of activating the respective fuel element 37 by detecting a change in airflow. The control circuit 41 operated by the sensor 45 supplies electric current to the respective heater element 37.

On the outside of the lighter 25, preferably on the front 33 of its housing 31, there is a marker 51 which indicates the number of sniffs remaining from the smoke of the cigarette 23 inserted in the lighter 25.

Preferably, the indicator 51 is a beta segment liquid crystal display. In a preferred embodiment, the indicator 51 displays the number "3" when a cigarette detector 53 detects the presence of the cigarette 23 in the heating element compartment 39. The tertiary detector 53 is preferably a light detector in the socket 39 of the heating element 39 that detects light from a plug 23. Label detector 53 provides a signal to control circuit 41, which signals to indicator 51, displaying an "8" on indicator 51 indicates that the eight sniffs in each of the 23 cigarettes are available, meaning that no fuel 37 has been activated in 23. to heat a cigarette. After the cigarette 23 has been completely withdrawn, the indicator 51 shows its number. When the cigarette 23 is removed from the collector 25, the tag detector 53 does not detect the presence of cigarette 23 and the indicator 51 turns off. The zigzag sensor 53 is modulated so as not to emit a constant beam of light and to unnecessarily burden the power source 35a. The preferred zigzag sensor 53 for the smoking system 21 is OPTEK Technology, Inc. (1215 West Crosfey Road, Carroiton, Texas 75050, USA). manufactured by OPR50Ö5 Label Detector,.

Alternatively, when displaying the number of remaining beeps, the sensor will indicate the system's active or inactive state (ON "or" 81 ''}).

Other devices may be used instead of the mentioned 53 tag germ sensors. One such option is the use of a mechanical switch to detect the presence or absence of cigarette 23 and the use of a reset button (not shown) to reset control loop 41 when inserting a new cigarette into lighter 25 such as gauge 51 to display "8", etc. . Power supplies, control circuits, sniffer sensors, and signaling devices for use in the smoking system 21 of the present invention are described in U.S. Patent No. 5,060,671 (PM 1337}, and U.S. Patent Application Serial No. 07 / 943.504, Pb 15500.

Preferably, the combined length of the 104 * op mouthpiece filter and the free-throw filter 102 is 30 µm. Preferably, the cover paper 6 'extends approximately 6 mm beyond the tobacco rod 60. Preferably, the tobacco rod 60 has a total length of 32 mm. In the preferred embodiment, other ratios, lengths, and diameters may be selected,

The tobacco rod 60 of the cigarette 23 preferably comprises a roll of tobacco web 66.

An outer wrapping paper 71 tightly surrounds the tobacco web 66, The outer wrapping paper 71 is held together by a longitudinal seam in the conventional manner for more conventional cigarettes, The outer wrapping paper 71 holds the tobacco web 66 in a free-flowing filter 74 and a tobacco insert 80

Preferably, the outer wrapping paper 71 is wrapped tightly around the tobacco web 66 so that it looks and feels like more conventional cigarettes. It has been found that the outer wrapping paper 71 can be produced using conventional types of cigarette paper, preferably flax paper having a permeability of about 20 to about 50 CORESTA (CORSSTA air per cubic centimeter through a minute, 1.0 kP of air per minute), more preferably about 30 to 45 CORSSTA, with a rice weight of about 23 to 35 g / Ή, more preferably approx. 23 to 30 g / H, and approximately 23 to 35% by weight, more preferably 28 to 33% by weight of filler (preferably calcium carbonate).

· / Ο

Preferably, the outer wrapping paper 71 contains little or no nitrate or other modified modifier. The relative 7Ί outer wrapping paper has a weight of approximately 2 oitráttartaiom 0 and _f 6 wt! more preferably less than 1%.

Preferably, the tobacco web 66 itself is comprised of a layer of tobacco aroma 70 around the base 68 and a tobacco rod 60 at the pointed end 72 of the tobacco web 60, and with it at 7.1. the outer wrapping paper is wrapped around the tubular free-flow filter 74,

The free-flow filter 74 structurally defines and holds the pointed end 72 of the tobacco rod 60 and allows the aerosol to exit from the inside of the tobacco rod with minimal pressure drop. The free-flow filter 74 also acts as a flow restrictor at the pointed end 72 of the tobacco rod 60. This, in our opinion, promotes aerosol formation when cigarette 23 is smoked. Preferably the free-flowing filter 74 at least? mm, which facilitates machine handling and is preferably annular, although other shapes and types of low efficiency filters are possible, including cylindrical filter cartridges.

At the free end 78 of the tobacco rod 60, the tobacco web 66 and, therewith, the outer wrapping paper 71 are wrapped around a cylindrical tobacco insert 60. The tobacco insert 80 is made separately from the tobacco web 66. The tobacco insert 80 is formed by a relatively short column of cut tobacco filler which is wound into and secured to the insert cover 84.

* φ * »»

Preferably, the tobacco insert 80 is manufactured on a conventional cigarette stick maker. In this process, the cut filler (preferably mixed) is converted into air continuous tobacco rods on a moving belt and twisted into a continuous tape forming a liner 84, which is then glued along its length and thermally welded. However, in a preferred embodiment of the invention, the padding cover 84 is preferably made of cellulosic web containing little or no filler or filler (less than 0.5% by weight of each) and preferably contains no lubricant or any bulking agent. A tobacco cartridge cover 84 is preferably small basis weight: below 15 g / m ^2, preferably 13 g / m ^z, A tobacco cartridge cover 84 high permeability, preferably approx. 20000 to 35000 CORESTA, more preferably approx. 25000 to 35000 CORESTA, and is preferably made from softwood pulp, manila hemp cellulose or other long fiber pulp. Such papers are available at

Papie.rfa.brik from Schoeiler und Hoescht GmbH (Postfach 1155, D-76584, Gernsbaek, Germany). 84 other paper covers suitable for insertion are TW 2000 paper from DeMauduit (Euimperie, France), 2.5 wt. containing carboromethyl cellulose additive.

The tobacco rod maker is operated such that the tobacco rod has a density of approximately 0.17-0.30 g / cm -1, preferably at least 0.20-0.30 g / cm 2, more preferably about 0.24 and 0. , 28 g / cm. The increased density is advantageous in order to prevent loose ends from being formed at the free end 7.8 of the tobacco rod 60. However, it will be appreciated that the lower density of the rod will allow the dowel column 12 to contribute to a higher ratio of aerosol to aroma in the smoke. Accordingly, a balance has to be struck between the aerosol yield promoted by the low rod length of the '82 tobacco column and the avoidance of loose ends by the higher rod density.

Preferably, the tobacco column 82 is a combination of tobacco and other blends of tobacco typical of the industry, such as light, burley (buriey - high alkaloid and nitrogenous ingredients grown mainly in Kentucky) and eastern tobacco, and optionally reconstituted tobacco, However, in a preferred embodiment, the cut filler material of tobacco column 82 is made of a light blend of burley ' ¹ and oriental tobacco of approximately 45:30:25 for the l'JS.A market, and does not contain reconstituted tobacco or other post-flavored flavoring. Optionally, expanded tobacco ingredients and flavors may be added to adjust the rod density.

The continuous tobacco rod formed as described above is cut according to a predetermined length of the tobacco insert 88. This length is preferably at least 7 mm to facilitate machine handling. However, the length may be between 7mm and 25mm or more, depending on the preferences of the cigarette tree. This becomes clear from the following, which is illustrated in Figures 4A and 4B. Figures 4 to 5 are described.

The length 86 of the tobacco insert 80 relative to the overall length 88 of the tobacco rod 60 is generally determined such that there is a cavity 00 between the tobacco filter 74 and the tobacco insert 80 along its length. The cavity S0 corresponds to the empty portion of the tobacco rod 60 and is in direct flow communication with the filter end 62 through the free-flow filter 74 of the tobacco rod 60.

As is particularly true in FIG. In FIG. 6A, the characteristics of the heating elements 37 are also taken into account when selecting the length 86 of the tobacco insert 80 and the relative position of the tobacco insert 60 along the length 60 tobacco. When a cigarette is properly positioned on the stop 182 of the fuel element holder 39, a heating element portion 92 of each fuel element 37 contacts the tobacco rod 60 in an area of the tobacco rod 60. This contact area is called the 94 fuel footprint. " 4A. In FIG. 6A, a double arrow indicates the area - the "heating pad footprint 94" - which is not part of the cigarette itself but represents the area of the tobacco rod 60 where the heating element 37 is expected to reach operating temperature when the cigarette 23 is smoked.

Since the heating elements 37 are at a fixed distance 96 from the stop 182 of the heating element holder 39, the heating element footprint 94 is uniformly located at the same predetermined distance 96 from the free end 78 of the tobacco rod 60 for each of the 23 cigarettes. is fully inserted into the lighter 25.

The distance at which the remainder of the fuel footprint 94 is located above the tobacco insert 80 is referred to as a 99 "fuel filler overlap".

Preferably, the filter end 62 includes a free-flow insert 102 located adjacent the tobacco rod 60 and a nozzle filter pad 104 at the distal end of the filter end 62. Preferably, the free-flow filter 102 is tubular and transmits air with very little pressure. Alternatively, other conventional low efficiency filters may be used. The internal diameter of the free-flow filter 102 is preferably. 2 to 6 mm, and preferably larger than the inside diameter of the free flow filter 7 4 of the tobacco filter 60.

The sucker filter pad 104 closes the end of the filter tip 62 for appearance and, if desired, for some filtering purpose, although the sucker filter pad 104 preferably contains a small,

- 25% efficiency filter.

Preferably, the free-flow filter 102 and the suction cup pad 104 are connected by a padding cover 112 to a combined pad 110. Preferably, the liner 112 is a porous, lightweight liner that is readily obtainable in the field of cigarette manufacturing. The composite insert 110 is connected to the tobacco rod 60 by the wrapping paper 64. The wrapping paper 64 is the wrapping paper used in the cigarette industry as is customary. The wrapping paper 64 may be cork or white or any other color according to decorative considerations.

Preferably, the shaped cigarette 23 of the present invention has a total bush width of approximately 62 mm. 30 mm of this is the combined insert 110 of the filter end 62. Accordingly, the tobacco rod 60 is 32 mm long. Preferably, the free-flow filter 74 of the tobacco rod 60 is at least 7 mm long, and the cavity 91 between the free-flow filter 74 and the tobacco insert 00 is preferably at least 7 mm long. In a preferred embodiment, the "heater footprint 94" is approximately 12 mm long and is positioned such that the heater 98 cavity overlap is 3 w. Thus, the heater footprint 94 covers the tobacco insert 80 at 9 nm.

It will be appreciated that the length of the cavity 91 and the length of the tobacco insert 80 may be modified to facilitate production, and more importantly, to adjust the smoking properties of the cigarette 23, including taste, draft and yield. The length of the cavity 91 and the degree of fuel filler overlap (as well as the fuel cavity overlap 98) can also be varied to adjust the response rate, improve yield uniformity (both sulfur inhalation and cigarette uniformity), and. to control condensation of aerosol on or around the heater.

In a preferred embodiment, the cavity 91 (the filler-free portion of the tobacco rod 60) is approximately 7 m to provide sufficient clearance between the heater footprint 94 and the streamflow filter 74. In this way, there is a gap so that the "heater footprint 94" does not heat the free flow filter 74 during smoking. excavation lengths are also suitable, for example, if manufacturing tolerances allow, the cavity 91 may be short, so as to be approximately 4 mm or less, or in the other extreme, well over 7 m, thereby creating an oblong filler portion of the tobacco rod 60. length. Preferably, the filler-free portion (cavity 91) has a length of approximately 4 to 18 mm, more preferably 5 to 12 mm.

The base web 68 physically separates the fuel elements 37 from the tobacco flavoring material, transfers the heat generated by the fuel elements 37 to the flavor material 70, and maintains the physical cohesion of the tobacco rod when handling the cigarette, inserting it into the lighter, and inserting tobacco.

The percentages and / or relative weights of the various components of the tobacco web 66 are described below.

Unless you do the opposite. or the contrary is readily apparent to one of ordinary skill in the art, the weight of the chips, the data refer to the dry weight, i.e., the percentages and / or ratios quoted are the same 35 «> * ·> ♦ *

Μφ »*« flat masses are corrected for moisture (not included).

Preferably, carbon fibers are not added during the manufacturing process of the tobacco web 66 as described in the following paragraph. At the end of the preferred manufacturing process, the base web 68 itself has a preferred total rice weight of about 35 to 45 g / m ² , more preferably about 40 g / m ² . At 40 g / m ² , the base web 58 preferably contains approximately 28 g / m ^{2 of} tobacco fiber and approximately 12 g / m ^{2 of} cellulose fiber derived from wood pulp or flax. Cellulose fibers serve as a cellulosic reinforcing material in the composition of the base web 68. It is advantageous to minimize the cellulosic fiber content of the core web 68 for subjective reasons (to avoid the taste of the cigarette paper). The ratio of tobacco fibers to cellulosic fibers at dry weight basis should be approximately 2: 1 to 4: 1. The preferred cellulosic material is unbleached softwood kraft pulp, but most pulp and flax pulp can be used.

Another possible reinforcing material of the base web 68 is cellulose fiber made from tobacco,

Although not particularly preferred, one side of the base web 68 may be coated with approximately 1 g / m ^{2 of} alginate. When alginate is used, it is advantageous to apply it to the side of the base web 68 facing the tobacco side 70.

Preferably, the tobacco material 70 applied to the base web 68 is at least twice as dry as dry weight, yet még φ «« ** ** ** ««. 4

More preferably, about 3 to 4 times the base web 68 is used. In a preferred embodiment, the tobacco material has a rice weight of approximately 130 g / rA so that the total total weight of the tobacco web 66 is approximately 170 g / m ² . On a dry weight basis, tobacco material 70 contains approximately 3.5: 1 to 5: 1 milled tobacco and extracted solids, although this ratio may be approximately 3: 1 to 9: 1. In a preferred embodiment, the ratio is approximately 4: 1.

Glycerol is added to the tobacco material 70 as a wetting agent and aerosol precursor, and is present in an amount of about 70% of the dry weight of the tobacco material 70. 10 to 14%, most preferably approximately 12%, but any value may be approximately 5% up to 20% relative to the dry weight of the tobacco 70. By reducing glycerol by 5 to 7% of the dry weight of the composition, the drum web 66 may become slightly stiffer and more resistant to flattening when rolled to a tubular shape.

Fectin is also added to the tobacco material 70, and its proportion of dry matter to dry matter is approx. 0.5 to 2 is preferably 1.4%. The pectin is added as a coating agent. In the absence of brakes, tobacco material 70 would be too absorbed - penetrate into base web 68 during the coating operation and create a granular surface texture on the coated side of tobacco web 66. Too much pectin inhibits penetration and weakens the bond between tobacco 70 and base web 68. At about 1% pectin promotes proper penetration and bonding of the layers of rock, so that the base web 68 can withstand the severe effects of automated cigarette manufacturing.

Most preferably, the tobacco material 10 on the base web 68 contains approximately 16 to 20% dry solids, 66 to 71% dry tobacco particles, 8 to 14% glycerol and approximately 1.4% pectin dry weight. For the US markets, milled tobacco in tobacco 70 is preferably a blend of light burley "and oriental tobacco, of which about half is floral tobacco, approximately one third burley" and the remainder is oriental tobacco. The composition and relative amount of the ingredients of the mixture may be advantageously modified to suit the preferences of the US market or other markets.

5A. and 5S. FIG. 6B illustrates a preferred method of manufacturing a tobacco web 66 as a base material, wherein the tobacco web 66 is formed into a form suitable for the automatic manufacture of cigarettes 23. In the first 120 steps, it is 100. The tobacco substrate, preferably the tobacco strip, is transformed into a continuous plating web 66s. In the second step 122, {58. FIG. 2B) converts the continuous tobacco web wrapper 66s into one or more rolls of tobacco web 66b which are in a condition such that they can be used for the automatic manufacture of cigarettes 23.

5A. Figure 120 illustrates the conversion of the tobacco raw material into a continuous tobacco web sheet 66s starting with the extraction of the tobacco raw material in the extraction step 124.

«**« ««

We are subjected to (preferably carrying) coinage to separate the tobacco fibers from the soluble tobacco material in the original material. The tobacco material preferably smokes but. other forms of tobacco and / or tobacco layers may be used in this process. Smokers are preferably a blend of light and 'burley' tobacco and may optionally contain oriental tobacco and other variants.

During the extraction step 124, the stacked tobacco fibers are formed into a continuous web of 6.8s in the papermaking process 126.

In the papermaking-type process 126, the tobacco fibers from the extraction step 124 are dispersed in water by adding a predetermined amount of cellulose fiber to serve as a reinforcing material in the composition of the base fabric 69. Preferably, the pulp fibers are pulp from wood, flax and / or tobacco stems. The mixed dispersion of tobacco and cellulosic fibers is refined after blending to give a thick slurry of 128 which is suitable for casting in the casting step 130. The dense web slurry 128 is directed into the layout of a casting machine for a web making machine and is cast onto an Eourdrínier continuous fine wire mesh or endless belt, preferably the former,

Refining a dispersed mixture of tobacco fibers and reinforcing material after mixing the two components is more expensive. Therefore I prefer to refine them separately, to mix them today. J |

Following the casting step 130, the resulting web 132 is passed through one or more driers in the drying step 134. Preferably, during this step, the web 132 is passed through a self-tumble dryer and one or more roller dryers, although many other arrangements and devices are known and available in the art for performing the drying step 134. THE

The drying step 134 is followed by a control step 136, which measures the moisture content and weight of the dried web.

A. The moisture value of output 1.38 is used to correct the drying step 134 so that the desired final moisture level of the base web 68s corresponds to the purpose of the next coating operation 144. The moisture content of the base web SSs is preferably horse weight in the coating process 144. or so!

value.

Returning to control step 136, the output value 140 obtained therein, i.e. the weight of the base web 68s, is used to correct the operation in the casting step 130 so that the base web 68 has a preferred rice weight as described above. And, the correction includes, among other things, changing the rate at which the dense web slurry 128 is introduced into the casting chamber of the fabric forming machine in the casting step 130.

The web-forming step 126 of the papermaking-type process may further optionally include a coating step 142. In this process, one side of the S8s base web is coated with an alginate. The amount of alginate is the same as the amount of fenugreek Xsez 63s applied to the side of the tobacco-containing flavoring material 70 as described in fen «♦ ♦ .9 * '♦» 4 The process is a preferred embodiment! however, no alginate is applied.

As a result of the process web forming step 126 of the papermaking type, the base web SS is in the form of a continuous core web 6Ss, on which the coating operation 144 can be performed. Alternatively, it is collected and then applied sequentially. However, it is advantageous to carry out a

144 Coating operations.

Preferably, the base web 68s enters the coating operation 144 with a moisture content of approximately 12 to 17%, more preferably 14.5 to 15.5 l.

Returning to the extraction step 124, the soluble portion of the tobacco leaves the extraction step 124 in the form of a dilute solution containing approximately 5 to 10 liters of dissolved tobacco ingredient, soluble substance, preferably 7 to 3% dissolved tobacco. Preferably, the diluted solution is not subjected to evaporative treatment because of its thermal effect on the solution. Exposure to heat can adversely affect the flavor provided by the soluble portions of the tobacco when they are smoked as part of the cigarette 23.

These soluble materials from the extraction step 124, also known as the "extraction liquid", are blended with additional finely divided tobacco, glycine and water and water in a mixing step 146. The relative amounts of these relative to each other are such that the final ratios previously described for the dried tobacco material 70 are obtained. The amount of water added or retained in the mixing step 146 is such that at the completion of the mixing step the solids content of the dispersion is approximately 20 to 35%, more preferably approximately 24 to 26%. The size of the milled tobacco particles in the blend is 60 to 400 bytes, whereby the term mes number means that 05% of the tobacco particles pass through a screen having a given number of apertures per square inch. More preferably, the size of the additional ground tobacco particles is approximately 200 messes, and most preferably about 120 meshes.

If the mesh size of the ground tobacco particles is greater than or equal to 120 mesh, and in particular between 180 mesh and 220 mesh, the solids content of the slurried tobacco material may be increased to approximately 28 to 31% at the end of the blending step 146.

After the completion of the mixing step 146, the resulting liquorice tobacco material is directly subjected to the coating process 144, although the coating process can be selectively performed at a later time out of line, in the coating process 144, approximately 22 to 27% by weight of the liquorised tobacco material. by weight of solids. It contains.

In the coating process 144, the liquefied tobacco material has 4 to 8% by weight, preferably 5.5 to 6.5% by weight, of soluble pumice material. It contains. tobacco liquorice

Preferably, the 144 coating process is carried out at a temperature in the range of from about 21 ° C to about 54 ° C (70 ° C to about 13 ° F), more preferably about 32 ° C to about -3 ° F to about ⁰ ° F.

Preferably, the coating operation 144 is performed on a conventional abrasive roller lubricator which, after a self-soaking dryer, is placed on an endless belt or on a continuous fine wire mesh of Fourdrinier. The coating process may be carried out with other suitable coating apparatus known to those skilled in the art of fabric forming, The tobacco material 70 is a .....

Ivett can be molded or extruded onto the base web 68. Alternatively, the coating operation may be carried out separately from the manufacture of the base web 68s. During or after the coating process, if desired, flavoring agents customary in the cigarette industry may be added.

As a result of coating operation 144, a continuous tobacco web 66s is produced.

58, the tobacco web sheet 66s is wound up into a roll of tobacco web 66b suitable for the automatic manufacture of cigarettes 23. Preferably, the conversion steps of the sequence of steps 122 are performed sequentially in the manufacture of the continuous tobacco web 66s. During the conversion steps of the sequence of steps 122, the operator must avoid conditions that may cause fractures, ruptures, and other defects in the tobacco web 66s so that the tobacco web 66b is continuously wound with little or no extension. In addition, the tobacco web sheet 66s must be conditioned so that upon completion of the conversion step 122, the tobacco web is not self-bonding and can be wound or wound rapidly from the roll web 66b.

Step 122 begins with drying step 46x. Preferably, the tobacco web sheet 66s is passed continuously through a gas fired hot air impact dryer such as Airtech Systems Corp. (Stroughton, USA) or a steam heated hot air dryer. Alternatively, other driers known to those skilled in the art of web weaving operations may be used, A. A minimum amount of heat should be added during the drying step 146x, but the amount of heat should be sufficient to maintain the base web 68s from its initial state (approximately 15%). moisture in the base web and approximately 75% moisture in the coating itself) to complete the 146x drying step so that the moisture content is approx. More preferably, the moisture content of the dried tobacco web sheet 66d is approximately 10-11%. This final moisture content is advantageous for a number of reasons: it facilitates the splitting operations at a later stage of the conversion step 122; adjusts the humidity level to approximate the equilibrium at which the material will be equilibrated when stored and / or delivered to a production facility; and adjusts a moisture level that avoids the wood web being sticky and self-bonding to the base web 66b-1b.

♦ ·· * ·· X *: · Χ

After the drying step χ 146χ, the dried tobacco web 66d is cooled to ambient temperature, preferably to the temperature expected at the storage site and / or associated manufacturing equipment. This temperature is usually between 31 and 44 ° C (65 and 80 ° F). This cooling step 148 not only facilitates the balancing of the tobacco web 66 according to the operating conditions, but also eliminates the risk of heat remaining in the tobacco web coil 66b, which may initiate a self-heating process. If self-heating is not. then, extremes of temperature and deterioration of the subjective properties of the tobacco web 66 may occur. Preferably, the cooling step is performed with a cold water cooled air cooler, available from Airfcech Systems Corp. (Stroughton, Maine, USA), although many other cooling systems are known to those skilled in the art of fabric forming.

After the 146x drying step and the 148 cooling step, the 66dc dried and cooled tobacco web disc is removed on a curling machine, such as Thermo Electron Plate Systems (Auburn, Maine, USA) or other curling equipment known to those skilled in the art of fabric forming. Upon completion of the curling step 150, the tobacco web 66 is substantially free of warping along its edges and is in a condition such that the next winding and splitting steps 152 may be performed. Prior to performing these steps, it is desirable to flatten the temperature, moisture content, and total weight of the tobacco web 66s leaving the curling step 150 for feedback and process control to ensure that the tobacco web and web 66s be in a condition suitable for cleavage, and the desired values of temperature, humidity, and total weight are obtained for the tobacco web rolls 66b.

The tobacco web 66 is primarily checked using its total weight. adjusting the coating operation 144, such as adjusting the feed rate of the slurry to the friction roller lubricating machine or the lubricating roller gap. The moisture level values obtained in control step 151 are used to control the drying operations to obtain the moisture levels previously described in the plates. Similarly, the cooling step 146 is controlled by the temperature of the tobacco web plate 66 as measured in the control step 151.

The tobacco web 66 is then wound up in step 152. The upliftment of a. is carried out on a web-winding machine well known and available to one skilled in the art of fabric processing. The winding web 68 is then cut into individual rolls of tobacco web 66b. The cutting width of the rolls corresponds to the desired circumference of the cigarette 23.

Upon completion of the conversion step 122, the roll of tobacco roll 66b is in proper condition for the automated manufacturing processes of the cigarettes 23, as disclosed in U.S. Patent Application Serial No. 67 / 943,504, filed September 1, 1932, incorporated herein by reference. United States Patent Application, U.S. Pat. The entire contents of this patent application are incorporated herein by reference.

Glycerol acts as an aerosol precursor in tobacco material 70 and promotes the formation of visible aerosol while smoking 23 cigarettes. In addition, as glycerol is released into the atmosphere, it is condensed and gives the appearance expected of regular cigarette smoke. Other wetting agents suitable for the tobacco industry may also be added,

After the molding step 123, one side of the base web 68 may optionally be coated with alginate before, during or after the coating step. The alginate coating provides additional strength and forms a film on one side of the 68 basic texts. However, the base web 68 is sufficiently solid even without the alginate and, therefore, preferably the base web 68 is produced without the alginate.

Other types of base webs 68 as carriers can be used in the present invention, including carbon fiber coats or metal or fiber coats known in the art and incorporated herein by reference, U.S. Pat.

Upon activation of each of the fuel elements 37, sufficient heat energy is transmitted through the outer wrapping paper 71 and the backsheet 68 to provide the aerosol of the dough 70 of the tobacco web 66 with the tobacco rod 60 which emits from the cigarette 23. person sniffing! As a result of its action, the 23 cigarettes are absorbed at the pointed end.

Typically, the smoker smokes the cigarette for 1.5 to 2.0 seconds, while the FTC cigarette test procedures are based on a 2.0 second sniff time.

Where the heater footprint 94 covers the cavity 91, the aerosol exits directly from the heated tobacco material 70 into the cavity 91, and then is sucked in or filtered through the filter tip 62 with very little pressure drop. However, where the heater element footprint 94 overlaps the tobacco insert 80, the fuel filler overlap 99, it is referred to as proximate portions of the tobacco insert 80 along adjacent portions of the tobacco web 66.

Accordingly, the mixed tobacco of the tobacco insert 80 contributes its own fraction to the total aerosol and adds its own flavor and other subjective properties. The aerosol emitted from the tobacco insert 30 during or overlapping the fuel filler 99 is gender-filtered and slightly depressurised as the tobacco insert 80 is absorbed into the cavity 91.

The nature and taste of the aerosol produced by heating the tobacco insert 80 may be modified by the tobacco mixture and the degree of overlap of the fuel footprint 94 over the tobacco insert 80. The aerosol component produced in the vicinity of the cavity 91 exits the cigarette more instantaneously because the cavity 91 has less inertia and because the cavity 91 does not heat

the shredded tobacco material has no pressure drop in the tobacco insert 80, but instead is directly connected to the filter end 62 through the free-flowing filter 74. However, its nature is different from that emitted from the tobacco insert 80, as it mainly exits the tobacco material 70, the aroma substance, on the base web 68. As will be explained in more detail below, it has been found that it is pleasing to the smoker that the aerosol dispensed from the 23 cigarettes advantageously contains both aerosol components and thus provides a direct release to the smoker and includes blends attributable to blended, cut filler tobacco. As _it: becomes apparent handwritten hereinafter apparent, the presence of the void 91 (and its immediate initial yield) of the cigarette 23 provides ja i puff. uniform smoking and promotes uniformity between cigarettes. This relationship improves the sniffer properties of partially filled cigarettes with cut filler 80 and 91 cavities according to a preferred embodiment of the invention with a first embodiment of cigarette 23 'without cut filler within the rolled tobacco web. and a second, alternatively, rolled fully filled with cut filler. with cigarette webs 23 'containing tobacco webs {7A. Compared. In these variations, the 66 'tobacco web and 66' ^! in a preferred embodiment, the tobacco web comprises a base web 68 and a layer 70 of tobacco material. In these variants, the 60 '* «* Xdehydes also contain an outer wrapping paper 71.

o An energy-adjusted, snake-shaped heating element was used in FIG. 6A. 6A and 7B. and Fig. 78.

The smoking cigarette in the electric smoking system 6A. The first alternative embodiment of FIG. 6B comprises an egv 6Ό 'tobacco rod and a filter tip 62'. Its components are shown in Fig. 4A. 1 to 4 are marked with apostrophe reference numerals. However, the tobacco web 66 'of the tobacco rod 60' of the cigarette 23 'has no cut filler and the free end 78' of the tobacco rod 60 'is provided with a backflow filter 200'. The base fabric 68 'of the tobacco web 66' comprises carbon fibers as described above. The structure of the cigarette 23 'is described in detail in U.S. Patent No. 5,388,594 (? 1697), the entire contents of which are incorporated herein by reference. In the following, this cigarette 23 'will be referred to as a filler-free cigarette 23'.

6C. Figs. 4 to 5 were performed on the smoking system 21. The outlet of the smoking machine was passed through a 6y opacimeter each time a sniffer. The 6y smoke meter has a transparent chamber 6v. The transparent chamber 6v passes the light beam 6u from the light source 6w to the light sensor 6z on the opposite side of the transparent chamber 6v. 6z

* ** ** The light sensor output signal is processed to determine the intensity of the 6u light beam reaching the light sensor 62. If tobacco aerosol goes for a. In a 6v chamber, this will scatter the 6u light beam so that any change in perceived luminous intensity is inversely proportional to the amount of total fine particulate matter (TPdj) in the aerosol. According to FTC Cigarette Testing practice, the smoker performs a standard two second sniff on the smoking system.

This information is shown in Figure 8B. FIG. On this. the luminous intensity recorded in the opacimeter is shown as a function of time during successive puffs of a filler cigarette 23 '. The data show the following trend: filler-free 23 ^! for a cigarette, the first and second sniffs are not consistent with the other three sniffs; the last three sniffs are much more consistent with each other; and the aerosol is released well before the end of each second of the sniffs. The yield of the filler-free 23 'cigarette is less consistent during the first few sniffs and is consistent only with subsequent sniffs. The first sniffing data is quite consistent with the observation that the machine-sucked filler-free cigarette 23 'produces less aerosol at the first sniffing unless corrective action is taken, such as perforating the 60' tobacco rod or other steps described in U.S. Patent No. 5,388,594. ), U.S. Pat.

7A. The electro-smokable cigarette 23 '' shown in FIG. 6A includes a tobacco rod 60 '' and a sharp end 62 ''. The components and the. arrangement similar to the preferred embodiment of Fig. 4A. Identical components are represented by reference numbers with two apostrophes. 7A. However, the cigarette 23 of FIG. 2B has a backflow filter 200 '' at its free end 78 and a cut filler column 220 extending across the length of the tobacco roll 60 '* between the backflow filter 200' and the free flow filter 74 of the tobacco rod 60. The 23 · '' cigarette 220 '' cut filler column contains a mixture of fourley, light and oriental tobacco, and has a rod density of 0.275 g / m · ³ . The base fabric 68 ' ^{4 of} the tobacco web 66 is of the carbon fiber type described above. In the following, the cigarette 23 will be referred to as a fully filled cigarette 23 ''.

In Fig. 73, the luminance measurement values obtained with the opacimeter 6y are plotted as a function of the time of each sniffer for one to seven weekly sniffs of a fully charged cigarette 23 '*. The data shown in Fig. 73 'show two recognizable trends in the properties of a fully-charged, filled-in cigarette 23': the first few sniffs yield significant aerosol yields, but the yield is then reduced to such an extent that the last three sniffs yield much lower yields. some sniffs (unless we take corrective action? and the fully filled, refillable 23 '' cigarette has an aerosol dispensing time54 and initial sniffs (first, second, and third sniffs} have a maximum yield of two seconds, after part of it.

During the first few sniffs, the fully filled filler cigarette 23 '*' tends to have a greater volume of aerosol delivery than the filler-free 23 'cigarette. 7B. 6B and 6B. The comparison of Fig. 7S illustrates this general observation if FIG. 1B shows the first few sniffs of a fully charged, cigarette 23 '' cigarette. 68 is greater than the first few sniffs of the filler-free 23 * cigarette in Figure 68! total area above the line. Figures 78 and 68 show the individual sniffs! the area above the lines is proportional to the total yield below that sniff.

It is believed that the delay in the yield of a fully-filled, filler-23 cigarette causes the smoker to smoke the cigarette longer, more strongly in response to not receiving a direct aroma response from the fully-filled, filler-23 cigarette. Stronger suction, on the other hand, can result in greater consumption ~ oxidation of the heated portions of the outer wrapping paper 71 '' and the tobacco web 66 '' by the additional air sucked in. In the first few sniffs, major fracture of the 220 ' collapse. In addition, in our view, once pyrolysis has begun in a fully loaded cigarette, it is expected to become more self-sustaining due to the presence and / or more compact state of the smokeless tobacco. Because air can penetrate the tobacco rod through the cracked burn sites of the first few sniffs, we believe that blood vessel cracks can shorten the desired airflow paths for subsequent sniffs. As a result, the yield of a fully filled cigarette 23 '' cigarette decreases with subsequent sniffs.

The data in FIG. 78 and the above explanation are consistent with the general observation that a fully charged filler 23 '' with electric collectors or a conventional cigarette has a tendency to decrease in yield as the sniffing progresses.

Because of the delayed but self-sustaining pyrolysis of a fully loaded cigarette 23 ', it is expected that it will produce a greater amount of aerosol at later stages of the sniffer, and sometimes even when the smoker is no longer smoking the cigarette. The latter situation may result in the production of a post-sniffer aerosol which may wander around the front part 3 of the collector housing 25, in particular at or near the heating element holder 39. Some of this post-sniffer aerosol will cause problems on the fuel elements, or will remain there long enough to be sucked into the cigarette 23 '' at the next sniff. Both of these consequences are detrimental to the provision of a pleasant and uniform taste.

* ϊ »· * *» * »χ

Returning to Figure 63, the sniffing lines of the filler-free cigarette 23 'show that the aerosol yield is maximal (where the sniffing! Lines are .lower), well before the end of a standard sniffing period of two seconds, and the yield is minimal in subsequent periods of sniffing. . Thus, in the case of degreased cigarette 23, the production of aerosol after sniffing ⁵ is not a problem. However, as mentioned above, the total volume of aerosol produced by the filler-free cigarette 23 'is smaller than that of a fully-filled filler cigarette 23', at times having a low consistency at the first few puffs, and does not have the subjective properties and flexibility a mixed (or even blended) cut filler would have a cigarette.

Figure 3 illustrates a filler-free cigarette 23 ', a fully-filled filler cigarette 23' and a preferred embodiment of the invention, Figure 1A. Figure 23 shows the comparative smoking data of the cigarette smoking machine 23 shown in Figs. In all these cigarettes, carbon fiber fur was used as the base fabric. As evidenced by the evaluation of the data shown in Figure 8, the partially filled filler cigarette 23 of the present invention provides a more uniform yield during suction. It avoids a decrease in yield with a fully filled cigarette 23 '' cigarette and yields a more uniform yield during the first few sniffs than a filler-free cigarette 23 ''.

The partially filled filler cigarette 23, which was analyzed to determine the data used in Figure 8, was half filled with cut filler, so that the overlap of the fuel element over cavity in the cigarette was relatively large, approximately 6 mm. The fuel cells 37 used to produce the data shown in Figure 8 were snake-shaped and provided 15 J of energy per heating cycle,

The data in Figure 8 shows the amount of aerosol produced during the first two seconds of each sniffer (mliligtambanj when smoking a particular type of cigarette as the sniffs progress. Compared to the data in Figs. 88 and 73, the aerosol amount in Fig. 78 corresponds to the integration of each of the sniffer lines from 0 to 2 seconds in FIG. 78 (the area defined above).

The data in FIG. 8 clearly show the decrease in yield for a fully filled cigarette filler 23 '' from the first sniff to the next sniff. In contrast, for a filler-free cigarette, there was no reduction in yield for a fully-filled filler cigarette 23 '',

The data of Figure 8 also clearly show that the uniformity of the yield of the partially filled filler cigarette 23 during the six sniffs is substantially the same as that of the filler-free cigarette 23 '. In addition, its cut filler contributes to the Taste and subjective effect.

II. The data compiled in Table 1A show that the heating element. How can changes in the extent of overlap in 23 cigarette cavities affect yields? The data in Table 1 were taken by machine smoking of partially filled cigarettes containing a 32 mm tobacco rod, a 7 m free-flow filter and a 30 mm filter tip at the pointed end of the tobacco rod. The 'fuel footprint' was 12mm long and centered on the tobacco cat in each cigarette.

Figure 9 is a graphical representation of the total amount of fine particulate material (TPM) delivered as a function of fuel filler overlap {mm}. The data shown here is using the standard test methods used to determine FTC tar levels, with a two-second sniff on Cambridge sheets on a standard smoking machine! The tested cigarettes were partially filled filler cigarettes having a carbon fiber core web and having a total length of 58, except that the data in Figure 9 were obtained with carbon fiber core webs and the same full length filler-free cigarettes. When the fuel-tobacco overlap was changed, the fuel-footprint was of constant length and the tobacco rod. centered on its center. Accordingly, any increase in fuel-tobacco overlap resulted in a proportional reduction in fuel-cavity overlap. The heater was a serpentine, and the heater foot print had mm 'approximately ⁵ 10th Taken together, the data show that there is a second order relationship between the total fine particulate material supplied and the degree of fuel filler overlap. The data in FIG. 9 and FIG. A separate set of data in Table 1 shows that modifying the degree of fuel filler overlap can produce the desired (target) level of yield in a partially filled, filled 23 cigarette cigarettes. <% ♦ · ♦♦ · «» »« * () lj ♦ · «♦ ♦ ** '» *

Modifying the degree of fuel filler overlap is the preferred method of achieving a desired level of tar in partially filled filler cigarettes. This is due, inter alia, to the fact that it has been found that changes in fuel filler overlap affect yields in a more explicit and controllable manner than changes in the density of the rod at the 80 tobacco pads. This method also allows the rod density in the tobacco insert 80 to be selected for purposes other than tar level adjustment, such as controlling the loose ends and / or the filter at the free end 78 of the tobacco insert 80 or otherwise facilitating manufacture. It also allows the tar yield to be variable. similar cigarette products without necessarily changing either the tobacco web 66 or the tobacco insert 80.

It is also advantageous to select relative dimensions of the partially filled, filled cigarette 23 and the fuel holder 39 of the collector 25 such that, when the cigarette 23 is inserted into the lighter 25, each fuel member 37 is positioned along the tobacco rod 60 so that at least some each "fuel footprint" should only be above the filled portion of the 60 tobacco rods - the cigarette insert. In such embodiments, the cavity 91 further facilitates

for aspirated aerosol components. In this regard, it should be noted that the edges 73 and 75 of the free-flow filter 74 of the tobacco rod 60 are between one side and the old 91, on the other side, and the free-flow filter 102. Due to the edges 73, 75, the free-flow filter 74 has a smaller internal radius than the other two adjacent areas - the space surrounded by the pseudorangle and the free-flow filter 102.

It is believed that the edges 73, 75, and possibly the free-flowing filter 74, with other adjacent portions, promote turbulence and other flow conditions favorable to aerosolize the particulate constituents emitted from the gas phase and the heated tobacco portions of the tobacco rod 60.

Figure 10 shows a cigarette 23a according to another preferred embodiment of the invention. The cigarette 23a has the same components and arrangement as in FIG. 4A. 23b, but in the cigarette 23a a reflux filter 200a is provided at the free end 78a of the tobacco rod 60. FIG.

This indicates that cigarette 23a can be used in an electric smoking system and is not to be matched with a match or conventional lighter than more conventional cigarettes. The mud filter 200a is depicted as a separate component of the wrapped tobacco insert 80a, but to facilitate the manufacture of the cigarette 23, the tobacco filler hood 80 may be combined with the non-illustrated tobacco liner 200a to provide a backflow w *. ♦ * * * X «* Μ * * Φ« ♦ ** * Φ ** Φ «X φ X« ♦ φ Ν Α «« ♦ filter. Backflow 200a! the cigarette 23a provided with a filter insert may be provided with a low rod density tobacco insert 80a without the risk of loose end or tobacco end 60 falling out of the tobacco rod.

In a preferred embodiment, the partially filled filler cigarette 23 may be designed and / or adjusted with the energy of the fuel elements and the fuel filler overlap in the design process. Accordingly, during the design of a partially filled cigarette cigarette 23, the density in the tobacco insert 80 is generally available to realize the desired degree of pressure drop at the free end 78, and / or to control backflow, similarly to another embodiment of the backflow 200a of cigarette 23a. szűrőjénél.

The cigarette case 23b is configured so that the heater footprint 94b overlays the tobacco insert 80b small 310b. in order to achieve an increased yield with lower rod densities. The high-density portion of the cut filler 320b has the function of preventing loose ends and backflow! restricts the axial transmission of air through the ubiquette rod in the same way as a filter.

The presently preferred embodiments of the heating elements are shown in Figures 12-21. are shown. The chair is a heating element for any one of the cigarette embodiments described above, i.e., 4A, 43, 6A,? and il. FIG. 2A is suitable for a fully-filled, partially-filled and non-filler cigarette and for modifications to these cigarettes,

In general, it is preferred that eight heater blades 121 are provided to generate eight sniffs when the heater blades 121 are actuated sequentially. Sz simulates the number of sniffs of a regular cigarette. The heater blades 121, starting from a hub portion 111, form a cylindrical heater blade arrangement that holds a plugged-in cigarette .23. The adjacent heater blades 121 preferably define a gap 129.

The. The number of sniffs and consequently the number of heater blades 121 are to be changed when the cigarette is inserted into the CR cylindrical vessel. The number of sniffs can be varied by providing the desired number of heater blades 121. This can be done by using blades of the same or different sizes.

The fuel holder is located in the opening 27 of the lighter 25.

The .23 Cigarette - Optional 200 Backflow Front! filter - inserted into the opening 27 of the lighter 25 into the substantially cylindrical space of the fuel holder 39, which is delimited by an annular cap 83. The heater holder 39 is provided with an open end for receiving a cigarette, wherein a cylindrical air channel sleeve 87, a heater assembly 100 comprising heater blades 121, a conductor pin 1A4A, or a common conductor as a common conductor of heater elements 10 or wires and spacers. The lower inner surface 81 of the spacer stops the cigarette 2.3 in the heater compartment 39 in the desired position such that the heater blades 1.21 are located in the cigarette 23 adjacent the cavity 79 φ φ *** φ Φ φ * φ * * * * * * ♦ · ♦ * * '** ♦ **** ♦ · * and, in a preferred embodiment, the foregoing embodiments 1 to 11. figure. are positioned as described.

Essentially, the entire racket 39 pounds is disposed within the lenite damaging position and is secured by a sliding fit with the front portion 33 of the lighter housing 31. The leading edge 93 of the cap 8-3 is located at or slightly outwardly from the first forehead end 29 of the lighter 25 and preferably has an internal chamfer that facilitates the introduction of the cigarette 23 into the fuser holder 39 and the heating member 39 from the rail. is equipped with a rounding. A. The current conducting pins 104A and 104B are preferably received by suitable sockets (not shown) and thus hold the impact element 39 in the lighter 25. The conductors from the sockets or the printed circuits lead to the various electrical elements.

Other pins may add extra support to the pivot assembly. The material of the current conducting pin 104A and 104S may be any suitable material, preferably tinned phosphor bronze. The channel 47 and base 50 in the spacer are in communication with the aspirating sensor 45 and the cigarette detector 53 detects that the fuel element 39 is a cigarette or no.

As shown in Figures 12 and 13, the heater assembly 100 is preferably a monolithic structure which is symmetrically arranged from a central hub portion 111 or as shown below.

It will be described with reference to Figure 19, which includes eight heater blades 121 extending in an asymmetrical configuration. As best illustrated in FIG. 13, the carriage 106 defines a substantially circular plug opening 360. The mouth portion 365 of the plug opening 360 deflects the plugged cigarette into a CR vessel having a smaller diameter than the plug 360. The plug-in opening 360 is defined by the end portions 118 corresponding to the connecting portions 118 of the heater blades 121 and the throat portion 365 by the portion of the connecting portions 118 between the connecting edge 118A and the end portion 118S. The diameter of the plug opening 360 is preferably larger than that of the plugged cigarette 23 so that the cigarette 23 is CB. and the diameter of the CK container is approximately the same as that of the cigarette 23 to provide a sliding fit for good transfer of heat energy. Preferably, the diameter of the cigarette 23 is approximately the same as the diameter known in the art. If the manufacturing tolerances of the cigarette 23 are acceptable, the progressively narrowing region or throat portion 365 between the outer end and the vessel CR may also serve to slightly heat the cigarette 23 to serve as the inner heating wall 121 of the vessel. As a limiting example, the inside diameter of the plug hole 360 is preferably approximately 3 w ± 0.5 mm and the inside diameter of the vessel CR is preferably approximately? mm ± 0.5 mm. The heating blades 121 may be curved inwardly to increase the thermal contact with the cigarette 23 by narrowing the diameter of the cylindrical vessel.

Each U-shaped heater blade 121 has a first portion extending from one end 111 to a first end or a heater blade 116A, a connecting portion 118 connected to the opposite end of the first section or heating pad 116A and a first end extending toward the hub portion 111 at a first end. ♦ Λ ♦ »* ** Φ * *» ♦ <♦ * ♦ »second stage or USB heater blade. The first US main paddle foot and the second heater pad 116B are separated by a relatively constant gap 125, and preferably the 116A and USB heater pads are not substantially parallel. 18 and 19 in rolled state. The heating pad blades in the USA and in particular to reduce unwanted tightening of the cigarette 23 in the direction of the cigarette insert 23 are continuous and are oriented so as to define a cylindrical CR vessel for the inserted cigarette 23.

Connecting section 118 is provided with a curved joint 118A to connect opposing inner edges of the USA and heater blades 1168 to form an elongated γ-shaped resistance path substantially parallel to the longitudinal axis of the inserted cigarette 23 and extending along the length of the cigarette 23, as described in more detail below. The curvature of the connecting edge 118A is approximately 180 ° to 20 ° so that a γ-shaped blade is formed and the curvature is concave to the hub portion 111 and convex to the plug port 360. The first end of the first U.S. heater blade may have a width greater than the hub portion 111 and approximately the same thickness to reduce the current portion 115 power density and power density relative to the remainder of the heater blade 116A, thereby decreasing the ohmic heating of the order 115. This widening further enhances the mechanical integrity of the heater blade 121 at the hub portion 111.

The second connecting end 122 of the second heater flap 1163 is preferably stepped relative to the main portion of the second heater flap 116B to facilitate electrical connection with the corresponding positive current conductor pin, More particularly; as shown in Figs. 12 and 13, the connecting end 122 has three portions 122A, which are substantially continuous portions of the main section of the second heater flap 116B. and a transverse section 122B of an inclined angle and an end section 122C generally parallel to section 122A. The sections of the connecting end 122 may be wider than the second heater leg 116S for increased strength. This further provides sufficient contact area for positive bonding at the connecting end portion 122C and further reduces the taxon density and thus the ohmic heating of the connecting end 122C. is stitch-welded to the positive 1B4B pin or otherwise electrically and mechanically connected thereto.

Another embodiment of the positive connection of the heater blades 121 is shown in Figures 14 and 15. Preferably, the connecting end 122 is not step-shaped as in Figs. 12 and 13, but is essentially a second, smoothly shaped, heater flap 1168. This simplifies the production to be described later. To reduce the possibility of short circuits between the positive connection end 122 and the hub portion 111 and / or the first heater flap 116A, which may occur, for example, when the smoker rolls or otherwise adjusts the inserted cigarette, an electrical insulating ceramic coating 300 is provided. connecting finally, the «*

Applied to the hub portion 111 and the end portion 115, in particular to the respective facing edges of these elements.

Preferably, the ceramic coating may be applied by any conventional means, such as plasma spraying, to the hub portion 111, the connection end 122 and the end portion 115 of the first heater blade 116-A. Preferably, the ceramic has a relatively high dielectric constant. Any suitable electrical insulating material may be used, such as aluminum oxide, zirconium oxide, mullite, cordierite, magnesium aluminate, phosphorus, combinations thereof, and the like. Preferably, zirconium oxide or other ceramics having a coefficient of expansion of snow close to that underneath are used. metal fittings to avoid differences in expansion and contraction rates, thereby avoiding cracks and / or peeling during operation. A. the ceramic layer remains physically and chemically stable when the heating element is heated. As thickness, for example, electrical insulators are approximately 0.0001 ~ 0.01 mm, or approximately 0.00005 - 0.006 mm, and more preferably 8.001 - 0.003 mm. Preferably, a portion of the connecting end 122 is uncoated. Positive current conducting pins 104B are then connected to this coating section as described. To simplify masking, the corresponding portion of the end portion 115 is not ceramic coated.

Ceramic can be applied, for example, in the same plasma spraying step to the gap 127 between the connecting ends 122 and the first flap 116A and to the gap 125 between the connecting ends 122 and the hub portion 111 so as to enhance the mechanical integrity of the heater assembly. 25, the size of this ceramic brain structure may be larger than shown. With or without this additionally applied ceramic, the ceramic coating electrically insulates the positive connecting ends 122 and reduces the width of the slits 127 and 125, but the protection against short circuits remains. Accordingly, the connecting end 122 and the first end portion 115 of the first heater blade II6Ά may have an increased area which further strengthens the vessel and, in the case of a ceramic hub part, increases the frame structure and further strengthens the heater assembly. In addition, such a ceramic coating smooths the sharp edges delimiting the slits 125 and 127, thereby reducing the likelihood of cigarette pinching and injury, particularly during insertion, removal and any alignment by the smoker. Alternatively, the entire heater blade 121, and in particular the first heater blade blade 11 and second blade heater blade 1168, is completely coated with a ceramic layer on one surface, such as the outside of the cigarette or on both the inner and outer surface and / or at the edges of the gaps.

For example, this ceramic layer may be approximately 0.002 mm of orangoon oxide. This strengthens the heater blades 121 and, if desired, gaps remain. Accordingly, the heater blades 121 may be thinner, e.g., from about 0.002 mm to about 0.006 mm. This increases the resistance of the heating path and allows the blades to be wider, thereby having a thermally larger interface with the inserted 23 cigarettes, while maintaining the same total blade resistance. This increased blade width, together with the ceramic layer, further strengthens the heating structure. In addition, a ceramic coating on the outer surfaces of the heater blades 121 facing away from the inserted cigarette 23 can prevent heat loss from the heated paddle to the environment.

Preferably, the ceramic is applied by plasma spraying or any other method described in the associated patent application, preferably by electron beam physical vapor deposition, to avoid residual stresses that may result from surface treatment and / or collision of particles during plasma spraying.

Each of the 121 heater blades forms an anti-heater heater. More specifically, the first end portion 115 of the first heater flap 116A is electrically connected to the negative terminal of the power source, and more particularly, the hub part 111 forms an integral extension or is mechanically and electrically connected to the hub part 111. The hub part 111, on the other hand, is electrically and mechanically connected to the negative current conductor pin 104A by stitch welding or other methods such as soldering or brazing. Preferably, two current conducting pins 104A are used for balanced holding, since the negative and positive connections serve to mechanically hold the heater. The hub portion 111 thus serves as an electrical common conductor for each of the heater blades 121. The negative connection of each heater may be individually made in all embodiments, for example by a suitable negative terminal applied to one end of the heater opposite the respective terminal 122 of the respective positive contact.

The corresponding positive bond to each heater blade 121 is made as described on the end portion 122C of the second heater flap 1163. The connecting end portion 12.2C is electrically separated or insulated by the slot 127 from the common hub portion 111, the slot 125 from the first heater panel box 116A, and in particular the first section 115 of the associated heater panel 121, and the slot 131 to prevent short circuits and to allow thermal expansion. Additionally, the ceramic coatings described may be optionally used. Alternatively, the connecting end portions 122C are connected to the ground.

The positive and negative connections described form their resistance, more specifically, a circuit for supplying current from a power source, for example, via a control circuit, to a particular heater blade 121, when the smoking system is aspirated by a smoker. The primary heated area of the blade is the first heater blade foot 116A, connecting edge 118A and second heater blade 1168. Accordingly, a portion of the inserted cigarette 23 under and in contact with an adjacent actuated heater blade 121 is heated to surface pattern, i.e. an oblong shape corresponding to the blade above. Heating is primarily by conduction and radiation, and some convection is likely to occur. In addition, the inserted cigarette 23 is heated between the legs, i.e., below the slot 125, by overlapping or incision and ♦ ♦ »cumulative radiant and conductive heat transfer from both the baffles 116A and 1163. If the gap 125 is too large, the desired overlap will not occur and the portion of the inserted cigarette 23 below the gap 125 will not heat up sufficiently. In addition, the radiant and conductive heat will heat up a portion of the inserted cigarette 23 slightly extending beyond the outer edges of the heating pad 116A and 1163. The various heated portions together form a heated area of the cigarette 23 which extends from the location slightly at the outer edge of the heater pad 116Ά of the actuated heater blade 121, below the heater pad 116A, through the gap 125, through the heater pad 116B and the heater needle pad 116B. corresponds to a sniff of the tobacco smoke produced. The size of the heated area depends on the geometry and heating characteristics of the blade and the sharp duration of the energy pulse. Preferably, the heater blade 121 is dimensioned and thermally designed to eventually heat up a sufficient segment of the inserted cigarette 23, such as 18 _m to produce an acceptable suction in response to the energy impulse generated by the smoker.

The relatively large end portions 115 and the connecting end 122 of the blade are not heated to these operating temperatures because their relatively large volume reduces the current density and thus reduces ohmic heating. The connecting section 118 also has a section which does not heat up to these operating temperatures because the heating stroke

It has a 118Α connecting edge, ά before the sattelite has a large volume so that it has a lower current density and less ohmic heating than the 118A connecting edge and directly adjacent sections. To further reduce unwanted heating in the rest of the link 118,

2; perforating the connecting section 118 to reduce the ohmic and / or heat conducting paths and / or adding additional heat sink material 113 to the connecting section 118 to reduce the heat transfer to the section as shown in Figure 6. To accomplish this heat sink function, a non-conductive material, i.e., a heat insulating material such as ceramic, is applied. Suitable ceramics include, but are not limited to, a mixture of aluminum oxide, oxonium oxide, aluminum oxide, zirconium oxide, mullite, and the like. as with the blades of the blades. All these modifications should be examined for their negative effect on the mechanical integrity of the connecting portions 113 which hold the running gear 100 and restrict the insertion and withdrawal openings for the cigarette 23.

After a heater blade 121 has received a current blast, a pre-mechatized minimum time elapses to allow the next sniffer, preheating of a portion of the cigarette 23 may cause unwanted and / or partial aerosol production or thermal degradation of the cigarette portion prior to desired heating. Further heating of the preheated portion may result in unwanted aromas and flavors.

if a longer suction than a pulse actuation of a heater blade is desired, then the control logic unit is configured to ignite another heater or further heater fuel directly after the first heater impulse actuation or during the final portion of the first impulse actuation . The additional heater blade may be a radially next running blade or another heater blade. The heater blades must be sized so as to obtain the desired total number of sniffs of the desired duration.

In one embodiment, the number of heater blades 121 is equal to the desired number of sniffers, e.g., eight. In another embodiment, the number of heater blades 121 formed is twice the number of sniffs, e.g., Sixteen element portions for an eight-sniff cigarette. This design allows for ignition sequences other than the normal sequential ignition for approximately two seconds and preferably the radially successive ignition sequence, in which the number of heater blades 121 is equal to the number of sniffs. For example, the logic circuit may be controlled such that two peripherally spaced heater blades 121 are provided.

that is, the heater blade 180 ° from each other at the same time receives ignition and thus co-heats the body of the cigarette to produce a sniff. Alternatively, one cigarette employs a first series of ignition of every second heater blade 121, followed by a second series of brains in which an intermediate heater blade 121 is ignited for the next cigarette. Alternatively, the first ignition sequence may be repeated over a predetermined lifetime of a plurality of cigarettes, and a second collection sequence is initiated. Any combination of heating blades can be used. The number of heating paddles may be less than, equal to, or greater than the number of sniffs of a single cigarette used. For example, a kilenolate blade system may be used for a six-puff cigarette, and for consecutive cigarettes a different set of six fuel elements is ignited and the other three fuel elements are not ignited.

The heater assembly 100 is electrically and mechanically relatively fixed at one end to the conductive pin I0AA by means of pins - the hub part 111 and the conductive pins 104B at the connecting ends 122. The current conducting pins 104A and 104B are preferably molded into the plastic hub portion or otherwise secured thereto, preferably to minimize air leakage. This fixed end is preferably opposed to the plug opening 360. The connecting portions 113, including the opposite ends of the US connecting edges 118B, define the plug opening 360. The end portions 118B may expand outwardly, thereby defining a throat portion 305. A 121 »φ * · *» *. «Χ 9Φ

The end portions 1I8B may expand freely upon heating, i.e. the end portions 1158 are not fixed. More specifically, each of the 1188 end portions is disposed in a corresponding channel 210 which is provided in the inner wall 201 of the collector cap 53. The radially outward movement of portions 1183 of the inwardly pre-tensioned heater blades 121 is stopped by the USB terminals contacting the radially outer walls of the channels 210. This sets the limit for prestressing and defines inward prestressing. This inward bias can be replaced by the inward manufacturing effort as explained above. As can be seen, the inner wall 201 expands outward, allowing insertion of a portion of the 1188 · end portions of the blades. The radially outer wall of channel 210 engaging end portion 1188 is dimensioned and shaped to permit insertion of a sufficient portion of blade end portion 11.8B so that the blade end does not exit from channel 210 when heating or cooling the blade or during the roll of the cigarette. when pulled out ♦ If desired, the outer wall may be provided in the radial direction with a support, such as a trapezoid, which contacts the 1188 ends. In another embodiment, the 1188 end portion has a rounding of the USD, or even an elliptical portion, of the inserted 1.188 ** 'before the end. This USD rounding allows the plunger to rotate in the channel 210 in response to ski thermal or mechanically generated torques, thereby holding the paddle portion in the channel 210. In addition or instead, the end portions 118B are more rounded.

In the first embodiment of Figure 12, the channel 210 is sized such that the end portion 1188 of the heater blade 121 translates, i.e., toward the end 202 of the channel 210, translationally as the cigarette 23 is inserted and / or heated so as to provide a clear contact with the cigarette 23. and between the blades,

The arrangement in which one end of the blade is open relative to the opposite hub portion allows longitudinal mechanical displacement and / or thermal expansion and contraction of the heating blades 121 during insertion and withdrawal of a cigarette and / or during heating and cooling of the heating blade, and In the second embodiment of Fig. 14, a support 204 - which may be trapezoidal - is formed in the channel 210 so that when the heater blade 121 expands upon heating or moves when the cigarette 23 is inserted, the end portion 1183 contacts the support 204 and allows to preload the heater 121 inward toward the 23 cigarettes inserted. Thus, it reduces tension on the blade and increases the desired thermal contact, i.e., the clamping forces between the blade and the cigarette. By rotation, it is understood that the heater blade 121 can rotate freely, but cannot translate, on this support 204.

Preferably, 100 smoke primers are monolithic structures, optionally coated with ceramic as described.

The material should be able to withstand approximately 1,800 to about 10,000 such pulses without xregfection, significant degradation, or undesirable deflection of the heating pad 121.

Preferably, the fuel element holder 39 may be disposed of separately from the lighter 25 which includes both the fuel elements 37 and the circuit. The latter are preferably discarded after 3600 or more cycles. When selecting fuel material and other metal components, account is also taken of their oxidation resistance and general lack of reactivity to prevent oxidation at expected temperatures and reaction with cigarette 23. Who-

If desired, the heater blades 121 and other metal components may be enclosed in an inert heat-conducting material, such as a suitable ceramic material, to further prevent oxidation and reaction.

However, it is even more preferred to make the heater blades 121 and other metal components from a heat-alloy having high mechanical strength and resistance to surface oxidation, while also having high corrosion resistance and degradability at high temperatures. Preferably, the heater blades 121 are made of a material of high strength and surface stability at temperatures up to 80% of the melting point.

A wide variety of elements can be used as additives in the KI3AI alloy. The major additive in the fuel layer is wage and silicon. In our opinion, the skin enhances the toughness of the boundary layer of the granules and is then most effective when the KigAi alloy is rich in nickel, for example AK-24%.

It describes. The materials of the fuel element may further be materials having similar properties.

The heater blades 121 shown in Figure 2 are arranged to protrude symmetrically from the hub portions 111. Asymmetric layouts are also possible. For example, several, such as six or eight cooling blades can be divided, for example, into two subgroups in which z;

slit selects a single, flat imitation that heat transfer from adjacent heater blades 121 of adjacent subgroups is minimized for the cigarette 23 below slit 135. Suitably, the slit 135 provides a wider, unheated and robust portion of the cigarette which is stronger than the unheated portion of the cigarette below the narrower slit 131. This improves the column strength of the cigarette 23 and thus facilitates the removal of the cigarette after smoking and heating and weakening of the parts. If desired, the logic unit may activate more than one heating element in a symmetrical or asymmetrical arrangement.

According to the invention, two

The use of US and IIbB heating mat significantly increases the amount of aerosol produced compared to that produced by the solid fuel element. The solid fuel element provides good heat transfer with the cigarette, but the mass transfer of the aerosol into the intake air stream is hampered by the solid structure, which prevents optimum delivery of outside air to the cigarette. This is particularly true if the housing of the smoking system is perforated so that the air outside the casing is in contact with the outside surface of the cigarette. The heater according to the invention, which has the same volume as a solid heater but has a larger circumference, provides a better delivery, for example through slot 125, and accordingly provides more aroma per unit of energy supplied to the baffle 121. As mentioned above, the gap 125 must be sized to provide optimum radiation overlap for a given blade geometry. Because larger amounts of aerosol are produced, the required weight of the blades can be reduced. At the same time, the same desired amount of aroma is produced. As a result, the unit will be lighter and the number of running pads and cigarettes inserted will be reduced

4 φ φ energy required for heating. This further reduces the weight of the unit as the power source, such as batteries, may be smaller.

As a non-limiting example, slot 125 has dimensions of approximately 0.51 mm [0.020 ''] approximately 0.127 '[0.005'']; the dimensions of the heating pad 116A and 116B are approximately 0.32 to 0.43 mm (0.0125 ~ 0.017 '') 1 kb, 0.127 mm [0.005 ''] wide and approximately 14 mm (0.55 '' 3 ± 0.127 e). ® | Q, 005 * '] revenge, and about 0.2mm} O, O8 ^!, 3 and about 0.25mm [0.010 ** 3 thick ± about 0.127mm [0.005 *'], and length from the edge of the hub portion 111 to the tip of the connecting section 118 is approximately 26.075 m [1.062 ''} ± approximately 1.50 mm [0.0625 ''}.

It has been found that a predominantly transverse or radial air flow relative to the inserted cigarette results in a more desirable smoke control than the predominantly longitudinal flow. Slots 125, 127 and 131 provide a path for air to. must be aspirated to come into contact with the inserted cigarette. Additional air ducts are provided to optimize the transverse air flow by the perforating sections of the heater blades.

Another version of the heating pad geometry is shown in Figure 16. Here, both the first heating pad 116A and the second heating pad 1163 are snake-shaped. The serpent shape of the ilŐA and the heating pad 1163 is parallel, so that the legs are equally spaced from each other, and the slot 125 is also serpent-shaped. The shape of the snake increases the circumference of the blade and thus improves aerosol delivery. This form of snake is described in more detail in European Patent Application EP-A0,615,411 and related application 08 / 380,718, filed January 30, 1995, as well as in U.S. Patent No. 63,538,8594.

The heater blades 121 are substantially parallel to each other, and there are gaps 131 between the opposite edges of one of the two heater blades 1163 and the first blade heater blade 116A of an adjacent blade. As noted, the heater blades 121 or symmetrically are arranged and have the same gaps 131 as shown in FIG. 18 or are asymmetrically arranged and, for example, have the same gaps 131 between adjacent heater blades 121 forming a blade subgroup 121A and a blade subgroup 1218, and a larger distance 133 is between two subgroups of width X, as shown in Figure 19. Note that the straight section 111A has two end portions, each of which is at least half the length X of one half to form a second distance 133 when rolled. These end portions86

The blades are configured as described above to form connecting sections 118 and heater blades 116A and 116B.

The sheet or strip of material is formed by any conventional method, such as by whipping or flame cutting such as CCb laser or YAG laser cutting. When using a strip format, the number of strip blades 121 may exceed. the number required for a cylindrical heating element assembly. The straight foal is then cut, if necessary, to form sections 111A from which the desired number of heater blades 121 extends. If section 122A, transition section 1228, and section 122-C are stepped, this step is formed by compression.

If a 3Ö ceramic coating is used, it is then applied by masking the press profile and applying, for example, by thermal spraying the coating on the Ilik section, the end portion 115 and the connecting end 122, or on the entire paddle or any portion thereof as described in the desired pattern. way. Alternatively, the ceramic coating may be applied after this rolling step or, if desired, before the blades are formed.

As is known, the heating element and the a. before each step of applying ceramic, mask the areas <

The section 11IA is then rolled to form a round hub portion 111. Section 111A can be rolled in any direction. Preferably, the section 111A is rolled such that the positive contact end portions 122C are at the connecting end 122 on the outer surface of the formed cylindrical heater, i.e., on the side opposite to the cigarette. This simplifies the connection to the current conductor pins 104B and avoids damage when inserting and removing the cigarette. The rolled section is rolled into a smaller diameter than the desired final diameter and then inserted into the apparatus. The rolled section then expands and the shape of the electrical connections is maintained. Alternatively, the rolled section is joined to form the hub portion 111, for example by any welding process such as spot welding or laser welding.

Preferably, each of the heater blades 121 is pre-tensioned to exert a heat sink 116A and € 11B and the US connecting edge to the inserted cigarette when forming the release assembly as shown in Figure 13. This pre-tension is preferably performed prior to rolling. , but can also be done after rolling. This pre-tensioning increases the thermal contact between the heater blade and the inserted cigarette, thereby improving heat transfer efficiency,

The efficiency of heat transfer is also improved by optimizing the surface area of the heating pads 116A and 116B which are in effective thermal contact with the cigarettes below. As shown in FIG. 11A and 1168, the bottom 117 of the heater flap 116A and 1168 (exemplified by the heater flap 116A) are slanted, i.e. flat across the heater foot. to improve the connection, the underside 117 is formed according to various non-planar geometries, such as angular or curved, to maximize the heated foot surface without undesirably increasing the volume and thereby reducing the current density and heater blade resulting in 17B and 17C, respectively. is shown. Preferably, the shaped bottom 117 does not drill any portion of the cigarette 23 to avoid weakening and possibly splitting the cigarette during insertion, administration, or removal. The center or tip of the underside 117 is preferably in contact with or close to the cigarette 23, and the remainder of the underside 117 is in radiation thermal contact with the cigarette 23.

Preferably, this shape of the underside is formed by pressing the heating pads 116A and 1168 of the heater blades 121 in a non-rolling state. This extrusion can be done at the same time as the above-mentioned pre-extrusion extrusion. The lower side extrusion also increases the 1.16A. ·. ·. ·. ·. ·.

A second manufacturing process is described. A suitable material tube is prepared. The heating blades 121 are then formed by any method, such as laser cutting. Alternatively, the blades are formed by countersinking a bed, inserting an internal ingot into the tube to form said blade profiles, and then using another sinker inside or outside to cut the profile. The profiled. if desired, 300 ceramic coatings may be applied to the tube as described above.

The present invention further minimizes injuries caused by thermal stresses. Since the heater blades 121 and the hub portions 111 form a monolithic structure, the stresses caused by the joining of the individual parts of the heater are avoided.

All embodiments of the invention are intended to provide the smoker with an effective amount of aromatic tobacco spray under normal conditions of use, and it is believed that 5 to 13 mg, preferably 7 to 10 mg, of aerosol should be delivered to the smoker. for eight puffs and each puff is a 35ml puff and lasts 2 seconds. We have found that in order to realize this yield, we have found in Art

The blades must be at the above temperature when in thermal contact with the cigarette 23. Preferably, the heating pads 121 should also absorb the specified energy. The energy requirement of the heater blades 121, which bend towards the cigarette 23 in a curve to improve the heat transfer connection, is lower.

The heating resistance is, of course, influenced by the particular heater power source 37, which supplies the electrical energy required to heat the heater blade 121. The heater resistances, for example, correspond to embodiments in which the current is four. provided by a series-connected nickel-cadmium cell having a total unloaded voltage of approximately 4.8 to 5.8 V, so alternatively, when six or eight of these series-connected cells are used, the heater blade 121 preferably has a resistance of approximately 3 ohms. approx. 5 ohms or approx. 5 ohms and approx. 7 ohms ven.

In another embodiment of the heater assembly of the present invention, the heater assembly 450 shown in Figures 20 and 21 comprises a plurality of heater elements 451. Each heater 451 has an elongated hollow shape, and each heater has a respective foot on both 452,

The foot end 453 is connected to the side wall of a cavity 430 near the end wall 443 of the cavity 430. Each foot end 452 is individually connected to the control circuit and ultimately to the power source for individual operation of the fuel elements 451, while the foot end 453 is connected together to the ground. Mud near the mouth end of the 430 cavity

The tips 454 are not electrically connected and therefore do not need to touch the sidewall of cavity 430, yet they are directed towards the sidewall of cavity 430 as shown in Figures 20 and 21, φφ to provide an introduction for the disposable part, i.e. the inserted cigarette, as described above. It should be noted that in Figure 21, the top and bottom heater elements 451 are shown with their apex 454 cut through.

In a further embodiment of the heater assembly shown in Figures 22 and 23, the heater elements 470 in the heater assembly 470 are slightly farther from the wall of the cavity 430 and each heater has a slightly sharper 7-shaped tip 472 and is provided with a fold 4747 to increase stiffness. . In this way, the heating elements 471 actually filter through the disposable portion and extend to provide the desired thermal contact. The open-cell structure described above is particularly suitable for such an embodiment. Since the heating elements 471 in this embodiment are further away from the sidewall of the cavity 430, the foot ends 452, 453 are connected to the end wall 443 rather than to the old sidewall 430. The leg ends 452, 453 are preferably connected to the end wall 443 through spacers 480 that do not conduct heat or current. In this way, the wiping effect wipes out the residual portion 452, 453 and the spacers 480 where the residuals are not reheated, as described in more detail in U.S. Patent 5,243,586. There are 412 perforations in the wall to draw in 420 parts of outside air as described in more detail in U.S. Patent No. 5,249,586, the entire contents of which are incorporated herein by reference.
