Abstract

Disclosed is a smokeless cigarette system comprising a reusable cigarette tube and a nicotine stick which can be discarded after use. The nicotine stick comprises a depot filter charged with a nanobead solution and nicotine and flavor substances attached thereto or incorporated therein, and a mouthpiece filter, which are joined together and produced at the factory stage. The disclosed smokeless cigarette is particularly suited for use in non-smoking areas to prevent stress caused by nicotine withdrawal and as a cigarette substitute, but can also be used in different types of cigarettes with varied dosage strengths to ensure gentle nicotine withdrawal and smoke disintoxication. Neither the environment nor other persons are harmed of put at risk by this system by either passive smoking or the generation of odour. The system can be handled in a simple and unproblematic manner since no heat source or heating systems are required.

Description

The invention relates to a new smokeless nicotine inhaler, preferably in the design and the outer dimensions of a cigarette, consisting of an inhaler, a mouthpiece and a depot filter with nanobeads and / or organic substances such as sugars or amino acids, wherein the nanobeads and / or organic substances such as sugars or amino acids, nicotine and preferably flavoring agents are incorporated or incorporated. It further relates to a method of making and using the smokeless cigarette. Areas of application of the invention are the healthcare, the luxury food industry, restaurants and public buildings.

In recent years, there has been an increasing trend towards smoking bans in public buildings or areas, at workplaces, in airplanes, on trains, in restaurants and inns etc. The reasons lie in the fact that smoking for the smoker in itself severely hazardous to health risks and on the other hand, the environment and non-smokers by the passive Mitrauchen are very vulnerable to health. Non-smoking bans, however, are usually for the smoker with significant stress situations and problems, e.g. Nicotine withdrawal etc., connected and lead to increased risk problems.

Proposals have already been made to eliminate the harmful effects of cigarette smoke without limiting nicotine effects (ia in DE-OS 102005016415A1 Title "NicStic filter connection for a smokeless cigarette").

However, the currently on the market smokeless cigarette systems all have a significant disadvantage. Since nicotine volatilizes only at a certain temperature (over 80 ° C) and thus can be "smoked", these systems must heat the nicotine and volatilize with heat, even with the addition of evaporating substances (eg alcohols).
This requires that these systems require additional equipment, such as heating rods in the cigarette tubes and charging stations for charging the heating elements. The fact that these devices then hardly match their size and / or weight with cigarettes is systemic. Above all, these devices do not reach temperatures of 80 ° C, so the nicotine yield is so low that practically no nicotine content in the smoke air (inhalation air) can be measured. The reason for this lies in the virtually or hardly existing volatilization of nicotine by weak heat sources.

The invention therefore an object of the invention to provide a smokeless cigarette that allows the smoker in the use of a smooth supply of the required nicotine, without heating and without electrical charges (accessories) that can be used anywhere and is universally applicable and the environment and the nonsmoker in no way polluted, neither by odors nor by harmful substances and condensates and thus represents an optimal compromise in the coexistence between smokers and non-smokers. Another object was to provide a simple and inexpensive method for producing a smokeless cigarette. This smokeless cigarette system, which is preferably a smokeless cigarette, is defined as a cold smoke cigarette.

This object is achieved by a smokeless cigarette according to claim 1, the manufacturing method according to claims 20-21 and its use according to claims 22-23. All other claims are preferred variants.

Quite surprisingly, it has been found that by filling a nicotine uptake with mineral nanobeads and / or other organics, e.g. Sugar, amino acids, etc., are attached to the nicotine and possibly other Flavourstoffe or stored and inserting the nicotine uptake in a mouthpiece a smokeless cigarette can be produced, which has particularly advantageous properties. In conjunction with an inhaler sleeve (cigarette tube) is a smokeless cigarette, which can be held and used by the end user analogous to a conventional cigarette in the hand and in the mouth.

Other particularly advantageous embodiments, such as material, density or weight, and preferred technical features, in particular dimensions, angles and radii, the cigarette tube (1) are made of Fig. 3 seen.

The new smokeless cigarette consists essentially of 4 parts which are factory finished or put together by the end user in use. Loaded nicotine uptake depot (2) and mouthpiece filter (3) are added to the factory Nicotine stick (5) composed. Nicotine stick (5) and cigarette tube (1) are brought together by the user immediately before use.

In accordance with the invention, the cigarette tube (1), depot filter (2) and mouthpiece filter (3) have been designed in the shape of a cigarette and the material, dimensions, holes, density of the filters and pore size of the filters are precisely matched and correspond to one another in order to achieve the desired nicotine intake, starch, at defined draw resistance (normal suction power).

The production process of the nicotine stick (5) is carried out in a newly developed production unit, which consists essentially of 2 different receiving shafts. Depot filters (2) and mouthpiece filters (3) are inserted horizontally into these receiving slots. Due to the special design of the shafts deposit depot filter (2) and mouthpiece filter (3) are opposite so that is guided by a double ejector pin depot filter (2), which is second last in the shaft, directed into the second-last mouthpiece filter to a defined depth , During this insertion of the depot filter (2) into the mouthpiece filter (3), the nanobead solution (4) is injected into the depot filter (2) via an injection system integrated into the upper ejector pin, which is driven by an external metering system. At the same time, the last finished nicotine stick (5), lowermost depot filter (2) inserted into the lowest mouthpiece filter (3), is ejected from the production well by the lower ejector pin. When returning the ejector pins now falls the top nicotine stick (5) down and the entire production cycle begins again. The production shaft system must be adapted to the dimensions of the depot filter (2) and the mouthpiece filter (3).
The height of the production shafts must be designed so that at least one reservoir of 15 to 30 filters is located in the shafts and the uppermost filters are always replaced by a feeder (see Nicotine Inking Robot) Fig. 4 . Fig. 5 . Fig. 6 . Fig. 7 . Fig. 8 . Fig. 9 . Fig. 10 . Fig. 11 ).

In practice, the smokeless cigarette is used by the end user by directing ambient air over the nanobead solution (5) by simply aspirating the mouthpiece, enriching the air in the depoctor with nicotine and flavourants, which are then absorbed through the oral mucosae and / or lungs become.

Particularly suitable is the use of the smokeless cigarette as a cigarette substitute in smoke-free zones.

Particularly suitable is the use of the smokeless cigarette as a smoking-nicotine by slowly reducing the nicotine levels in the smoking cessation.

The invention thus provides a completely novel nicotine inhaler, preferably in the form and appearance of a cigarette, in which the user smokelessly defines pure nicotine and prevents the symptoms of the withdrawal of smoke and neither pollutes nor pollutes the environment passive participation of uninvolved persons takes place. The shape, design and packaging of the nicotine inhaler are based on a normal cigarette and influence the psychological and positive effect of a replacement cigarette in the smoker.

After a simple implementation of the invention, a depot filter (2) with nanobead solution (4) is loaded and introduced into a mouthpiece filter (3) to a defined depth. This part composition is defined as nicotine stick (5) and factory made and packaged. To the packaging, a reusable cigarette tube (inhaler sleeve) (1) is placed.
The user introduces the nicotine stick (5) from the package into the cigarette tube (1), smokes the nicotine stick (5), like a cigarette, and discards the nicotine stick (5) by pulling it out of the cigarette tube (1) Smoke similar to a cigarette butt. The cigarette tube (1), however, can be reused. The nicotine stick (5) has smoked off as soon as the flavor taste has faded. Smoking off the nicotine stick (5) takes about 3 to 5 minutes, much like burning a normal cigarette. This inhaler system (cold smoke system) according to the invention is especially suitable for smokers and serves as a smokeless replacement cigarette for smokers in places where a strict smoking ban applies.
