Description

CIGARETTE WITHOUT SMOKE DESCRIPTIVE MEMORY The invention relates to a smokeless cigarette according to the generic term of claim 1. In DE 103 21 379 A1, from which the generic term of claim 1 is derived, a smokeless cigarette is described, whose body of reusable cigarette is formed of a thermal plastic cover with a layer deposed in vapor phase heat reflecting, as well as configured with a heat source that has been introduced in such a way in the cover that channels of air currents are created. A non-reusable nozzle contains a nicotine aroma deposit and a filter. The heat released by the heat source heats the air absorbed by the consumer through the air channels, which heats the nicotine aroma deposit and thus releases the nicotine and flavoring substances contained in the tank, which are absorbed by the consumer or smoker after passing the filter. Due to the nicotine feed without smoke, this allows an intensive enjoyment of nicotine without residues of combustion products and without disturbing the environment. DE 297 13 866 Ul describes an electric hot air adapter for cigarettes that allows smoke-free enjoyment of a cigarette, by placing a cigarette in the pod-shaped adapter, which It contains a thermal camera and a heating element. The air sucked by the smoker is heated in the thermal chamber and the heating element and reaches the cigarette, where without burning the tobacco releases the flavoring substances of the tobacco. DE 199 35 706 A1 discloses a smokeless cigarette whose cigarette body contains an incandescent filament fed by a battery, which heats the air aspirated by the smoker. The aspirated air flows through an exchangeable nicotine filter, whose nicotine is released by the heated air, so that it can be inhaled by the consumer. DE 40 06 887 A1 discloses a smokeless cigarette whose body contains as a heat source a capsule in which a heat generating reaction can be generated. With the heat you can release an aerosol that can be inhaled through a filter nozzle. From DD 298 347 A5 a cigarette is known to operate without combustion and containing tobacco and a non-combustion heat source which, physically separated from the tobacco, is used to heat the tobacco. The basis of the invention is to provide a cheap and easily manageable possibility that allows the smoker not to renounce the intensive enjoyment of nicotine or an aromatic stimulant, for example similar to classic cigarettes, and that the environment is not affected by the smokers This objective is met with a body of cigarettes according to with claim 1. The invented reusable cigarette body, which does not contain its own heat source, is inexpensive and allows by heating the heating tube a rapid heating of the stimulant for a sufficient time. Claims 2 to 5 are directed to advantageous improvements of the invented cigarette body. Claim 6 characterizes the cigarette in its entirety, which is further refined with the features of claim 7. Claims 8 to 10 are oriented to a cigarette die. Claims 11 to 13 characterize an adapter by means of which the invented cigarette can be connected to a heat source. In developing the adapter according to claim 12, the invented smokeless cigarette can be handled in a manner similar to a conventional cigarette. Especially the "lighting" of the cigarette with a lighter is a psychological component that matches the normal use of a traditional cigarette that is effectively ignited. Claims 14 and 15 characterize a cigarette box in which the nozzles intended for a single use are stored with the reusable cigarette body. With the invention is created the possibility of maintaining the subjective components of the enjoyment of smoking traditional cigarettes and in Special to avoid the inconveniences to the environment associated with traditional smoking. The invented cigarette can be "turned on" or put into operation like a conventional cigarette by putting it into operation with a cigarette lighter. The heat generated by the lighter causes the evaporation or solution of the stimulant stored in the tank, for example nicotine with flavoring substances, so that the stimulant is readily available and can be enjoyed intensively. In this enjoyment there are no harmful substances of traditional smoking, such as pitch and combustion products. Since there is no smoke in the environment there is no passive smoking among people around. When the smokeless cigarette invented cools after a long use, without the stimulant having run out, then it can be quickly put back into operation by a new "ignition" with the lighter, in order to finish the stimulant. The invention is described below on the basis of schematic diagrams by way of example and in more detail. The figures represent: Fig. 1 in exploded view, cross sections of a nozzle, a cigarette body and an adapter, Fig. 2 a side view of a lighter, and Fig. 3 a view on an open pack. Fig. 1 shows side-by-side the cross sections of a nozzle 10, a cigarette body 12 and an adapter 14.

The completely cylindrical nozzle 10 consists of a filter material known per se, as used for example for the filter nozzles of conventional cigarettes. A front part of the nozzle 10 is configured as a suction hole 18. The front part of the nozzle 10 opposite the suction hole 18 is designed with a cylindrical hollow 20. The surface 22 of the nozzle 10 is formed by closed alveoli with the exception of of the hollow surface as well as the left front side according to the configuration of Fig. 1. The body of the cigarette 12 has a cylindrical cover respectively a body 24 of thermally insulating material, for example a ceramic material, containing a thermal tube 26 of a material that is a good conductor of heat, such as copper. The left end according to Fig. 1 of the thermal tube 26 protrudes from the body 24, where the outer contour of the protruding area 28 approximately corresponds to the contour of the recess 20. The front side of projecting area 28 is open and on the wall In this case, the cylindrical portions of the protruding area are preferably formed with boreholes 30. It is also possible for the front side to be closed and then to be configured with at least one additional inlet hole. The body 24 is configured at its rightmost end with a recess 32 in which the right end of the heat pipe 26 freely rests. The right side of the body 24 forms together with the opening of the heat pipe 26 an air inlet which is connected to the air inlet at the left end of the heat pipe 26 by means of an aeration channel formed by the interior of the heat pipe 26. The cigarette body 12 forms together with the nozzle 10 for example, an imitation whose appearance corresponds to that of a conventional filter cigarette. The adapter 14, which can be made, for example, in sheet metal, has a bushing 34 as shown in FIG. 1, which forms an entrance hole 36 for inserting the right end according to FIG. 1 of the cigarette body 12. At a distance of the bushing 34 is the adapter 14 formed by a single piece 38, which for example shows two arms 40 bent upwards (in FIG. 1 only one is visible), which have not been closed in a complete bushing, but can be stretch elastically Between the bushing 34 and the part 38 there is a bimetal plate 42, which at a normal room temperature has a position approximately parallel to the axes, and that when heated is bent upwards, so as to close the bushing 34. A lighter known per se, as can be used for the invented smoke cigarette, is shown in Fig. 2 and identified in its set as 44. The lighter 44 has a body 46 in which the fuel is contained, such as a liquid gas. At the end 48 of the body 46 there is a burner nozzle which receives air through the air inlets 50, so that when the lighter is ignited by the button 52 a flame tip 54 of the end 48 appears. The function of the described components is the following: The mouthpiece 10 receives in the interior part of the hollow 20 a layer of a volatile stimulant 58, for example nicotine with odorous additives and / or flavoring agents. In its delivery condition, the nozzle 10 can be, for example, covered with a plastic film so that the stimulant can not evaporate. After removing the plastic film, the nozzle 10 is placed on the protruding area 28 of the body of the cigarette 1, so as to create an assembly that looks like a traditional cigarette (nozzle with a cigarette body). For the "ignition" the right end according to Fig. 1 of the body of the cigarette 12 is inserted in the entrance hole 36 of the adapter 14. Next, the adapter 14 with its part 38 is placed on the end 48 of the lighter 44. It is understood that the adapter 14 can also be placed on the cigarette lighter 44 and the cigarette is then introduced into the inlet opening 36. The opposite movements of introduction of the body of the cigarette 12 into the bushing 32 as well as of the end 48 of the cigarette lighter in the piece 38 are favorably limited by the stops configured in the adapter 14, so that the geometric assignment of the lighter to the body of the cigarette 12 and therefore of the flame 54 to the heating tube 26 are well defined when the flame 54 has a predefined form. In this way, the deformation of the bimetal plate 42 can be adjusted to the heating of the heating tube 26 and thus also to the heating the stimulant 58 and the outside of the body of the cigarette 2 held in the hand, so that - for a corresponding adjustment of the caloric conductivity of the cigarette body - its outer surface only warms slightly, although the stimulant 58 has surely reached its temperature of dissolution or evaporation of for example between 50 ° and 60 ° C. The lighter is operated with the push button 52, so that the flame 54 is inserted into the recess 32 and the left end of the heating tube 26 is heated, so that the stimulant 58 evaporates or dissolves. In case of sufficient heating of the heating tube 26, that is, in case of a sufficient duration of the flame 54, the bimetallic sheet 42 is heated and straightened in such a way that the smoker or smoker already holds the mouthpiece 10 with the lips You can unplug and remove the cigarette lighter. In cigarette consisting of the nozzle 10 and the cigarette body 12 is available for enjoyment as a normal cigarette after removing the adapter 14, since the stimulant 58 is maintained by the heating tube 26 at a temperature sufficient for evaporation during a sufficiently long period, due to its high heat capacity. When sucking air through the suction opening 18 this air flows through the heat pipe 26 and its passage opening 30 along the surfaces of the hollow 20 coated or embedded with the stimulant 58, so that the air collects the evaporated components and other volatile components of the stimulant 58, which may be enjoyed in the mouth or by inhalation. The dimensioning of the adapter 14 and the insertion lengths of the lighter in the adapter and on the other hand of the cigarette in the adapter are such that the tip of the flame 54 is located concentrically at a short distance from the right end according to Fig. 1 of the heat pipe 26. The piece 38 has been made in such a so that the air inlets 50 remain essentially free, so as not to disturb the supply of air to the flame with the adapter. The flame 54 is located mainly in the area between the bushing 34 and the part 38. The invention can be modified in multiple ways For example, the nozzle 10 must not necessarily have a filter material. The recess 20 can be configured in the body of the cigarette 12, so that the nozzle is formed with a corresponding projection. The body 24 and the heat pipe 26 can be configured as a single piece, for example by making the cover as a multilayer body, consisting internally of a material of high heat conductivity and maximum heat capacity and externally of a material with low heat conductivity Alternatively, the body 24 can be configured similarly to a thermos in several layers with a vacuum between the layers. The heating tube 26 can be configured solid as a heat conductor and for storing it with a high heat capacity in a material with a good heat conductivity, the right end according to FIG. 1 being designed with the largest possible surface, for example by stretch marks. In this case, an air channel is formed, for example, along the heating conductor by means of a groove in the "bar". heat and / or cover and conducts along the longitudinal members in the groove 20 and / or the front area of the heat bar towards the nozzle.The adapter can also be constructed differently, for example in such a way that the connection of the The body of the cigarette 12 is suitable for the cigarette lighter of a vehicle The adapter then has a heated piece that comes into direct contact with the heating tube 26 and is heated by inserting the adapter into the lighter until the heating tube 26 or the gap 20 have been heated sufficiently, for example up to 50 ° to 60 ° C. Instead of the lighter described, any lighter can be used, lighters with long flame being preferred.An accessory can be offered a cigarette lighter adapted to the invented cigarette that burns with a As a stimulant you can use liquids or powders that are placed in the hole 20 or with the ones that are respectively covers or impregnates a part of the nozzle. Depending on the taste of the consumer, different stimulants may be used, such as nicotine with fragrant additives and / or flavoring agents, etc. Alternatively, the stimulant may be contained in the central body of the stimulant itself, which is placed as a tablet in the hole, but which covers the entire gap as a cover. It is understood that the stimulant available as a separate piece is porous or configured with through holes and is placed between the nozzle and the air vents of the heating tube. The mouthpiece itself is reusable especially in case of Such stimulant carriers, since it consists of a material that is hygienically easy to clean. Fig. 3 shows a view of a box 60 in which the invented cigarette can be stored in the same way as in a conventional cigarette box. In a compartment 62 can be stored the reusable cigarette body 12, configured in different qualities. A compartment 64 is for storing an adapter. The compartments 66 are provided for storing the single use nozzles, preferably sealed. In the example shown fourteen nozzles 10 could be stored in the pack. The nozzles 10 are bought commercially or in vending machines and put into the pack 60. The pack 60 represented thus corresponds to a traditional pack with fourteen cigarettes traditional The filling of the pack 60, which can be configured as a high quality pack with a lid not shown, is relatively cheap, since it is only necessary to renew the nozzles 10. In one of its different configurations the nozzle 10 can be designed as reusable . The recess 20 can then be repeatedly coated with a stimulant which is composed in such a way that it can be spent completely without leaving any residue.
