Abstract

The invention relates to a smoke-free cigarette, which provides the user with just nicotine and no toxic and/or carcinogenic compounds. The above is achieved whereby the above comprises two pieces, a reusable piece with a thermoplastic sleeve with a deposited heat-reflecting coating (4), an air inlet opening (5) and a heat source (7), mounted in the sleeve such that air flow channels (6) are created with a star-shaped or wave-shaped form and an exchangeable non-reusable piece with a nicotine and aroma deposit (3), optionally a nicotine meter/usage display (2) and a filter (1). The heat released by the heat source heats the air sucked through the air flow channels by the consumer and passes through the deposit (3) such as to release the nicotine and aromas present in the deposit which, after passing through the filter (1), may be consumed by the smoker.

Description

Description of the NICSTIC REFILL SYSTEM
Field of application 1. The invention of the smoke-free cigarette (NICSTIC REFILL SYSTEM in the following) should prevent the toxic materials (tar, carcinogenic compounds like, inter alia, hydrazine, chrysene, arsenic, cadmium, benzapyrene, benzanthracene, formaldehyde, nitric amines) occurring during conventional smoking and to supply the consumer only the nicotine with aromatic substances desired by him.

2. At the same time the aim of the subject matter of the invention was, apart from the supply of the nicotine, to achieve an as close as possible approximation of the normal smoking, namely by a) retaining the shape of the cigarette, b) retaining the conventional filter tip, c) producing the agreeable feel of heat occurring during inhalation, and d) retaining the flavour of,the tobacco thus facilitating for the smoker the change from normal cigarettes to the NICSTIC REFILL SYSTEM.

3. By the smoke-free nicotine supply the consumer of the NICSTIC REFILL
SYSTEM can satisfy his nicotine requirement in the face of the ever-increasing prohibition of smoking (aeroplanes, railway stations, public buildings, restaurants) as well as in households (living rooms, children's rooms), without irritating and/or injuring third parties (passive smokers) and without violating the ban.

4. Due to the fact, that the NICSTIC REFILL SYSTEM can offer variable strengths of nicotine deposits, in an ideal manner it can be used to break the smoke-nicotine habit.

Description of the invention 1. The smoke-free cigarette (NICSTIC REFILL SYSTEM in the following), subject mater of the invention, is exactly the size of a conventional cigarette.
2. The NICSTIC REFILL SYSTEM comprises four parts:
2.1 an exchangeable, non-reusable part, namely the filter (1 ), nicometer-consumption meter (2) (optional) and the nicotine deposit, incl. aromatic substances (3) (Fig.1 ), 2.2 a reusable part (Fig.2), namely the jacket (4), coated with thermoplastic material, with an air inlet opening (5), air-flow channels (6), these shown longitudinally sectioned in Fig.2 and cross-sectioned in Fig.3, a star-shaped heat source (7) in Fig.3 and a wave-shaped heat source in Fig.4 and a 15. trigger/igniter (8), while by virtue of the smaller diameter (relative to the reusable part) and the length of the nicotine deposit on the one hand and a corresponding space, left free, in the reusable part on the other, a slipping-on of the exchangeable part according to Fig.1 up to the filter or the nicometer/consumption meter, incl. filter, the diameter of which corresponds exactly to the reusable part, is assured, 2.3 alternatively, a reusable part (Fig.S), namely the sleeve (9) from a thermoplastic material with a plug-in connection (10) to the charging station in the air inlet opening (11 ) to the heating coil (12), with a heat-storing medium (13) and air-flow channels (14), while due to the smaller diameter (relative to the reusable part) and the length of the nicotine deposit on the one hand and a corresponding space, left free, in the reusable part on the other, a slipping-on of the exchangeable part according to Fig.1 up to the filter or the nicometer/consumption meter, incl. filter, the diameter of which corresponds exactly to the reusable part, is assured, 2.4 and together with the part discussed in 2.3 from a storage and charging station configured in the form of a case (Fig.6), said station connecting, via the plug-in connection (10), the heating coil (12) present in the reusable part (Fig.S) to the charging compartment (15), and heating it until the thermostat (16) terminates the heating process and simultaneously signals the application time by the LED indicator (17) displaying the green colour (previously displaying the red colour); the fourth part further comprises a storage compartment (18) for two or further parts in accordance with Fig.5 which after the removal of the heated-up reusable part can be placed into the charging compartment for the purpose of heating up and then are immediately available again to the smoker after consuming the first "cigarette"
and a further storage compartment (19) for the non-reusable parts (Fig.1 );
the storage and charging station further comprises a battery in a battery compartment (20), that is connected via a plug-in opening (21 ) to charge the battery.
3. Instead of releasing the nicotine during the burning of the tobacco, the nicotine is bound in a nicotine deposit (3), that is situated directly in front of the filter, and is released together with the tobacco aromatic substances by the heated up air and inhaled by the consumer.
4. The heating of the air is carried out by the energy stored in the heat source ( 7 ) The energy is stored either in the form of crystallisation heat , that is activated by the trigger/igniter (8), or is released by a heat-storing medium (13), that is adequately heated up by the heating coil (12). The heat, occurring after the activation, is sufficient for approx. 1-3 minutes to inhale heated air, that can release nicotine (in a quantity individually desiredlchosen by the consumer), corresponding to one cigarette. At the same time it is assured, that the heat will be released evenly during a period of approx. 1-3 minutes. Even if the inhalation is interrupted, due to the released crystallisation heat/released heat of the heat-storing medium, no disruption, no danger, will occur, since the heat can be released also through the air intake opening.

5. The heat source (7) is fed by a material, that after crystallisation and heat release can be "recharged" up to 3000 times by supplying heat (by a water bath in hot/boiling water) or from a heat-storing medium (13), that is heated shortly prior to commencing the smoking by supplying electric energy via heat coils according to Fig.6, while a charging to carry out each of the multiple smoking processes and an overall serviceability lasting for years is ensured by a battery (rechargeable through any power point).

Claims

claims

1. A smoke-free cigarette, characterised in that it comprises two parts, a reusable part with a jacket (4) coated with thermoplastic material with a vapour-deposited heat-reflecting coating, an air inlet opening (5) and a heat source (7) that is included in the coating in such a manner that air-flow channels (6) will be produced with star shape (Fig.3) or wave shape (Fig.4), and an exchangeable, non-reusable part with a nicotine-flavour deposit (3), optionally a nicometer/consumption display (2) and a filter (1). The heat, released by the heat source, heats up the air inhaled by the consumer through the air-flow channels and passes in a heated state through the deposit (3), consequently releases the nicotine and the aromatic substances situated in the deposit and after passing through the filter (1) can be absorbed by the smoker.

2.
