Benefits of technology

[0010]The objective of the invention is to disclose a new type of smokeless smoking article which is simple in structure and operation and wherein the heat source quickly reaches the temperature of the optimum volatilization region of tobacco without a separate addition or chamber of liquid / water. A further objective of the smoking article of the invention is to provide a smoking experience to the smoker without combusting tobacco or other ingredients, without outside smoke and without generating any combustion products, such as carbon monoxide. One specific objective of the invention is to alleviate the problems referred to above.

Problems solved by technology

It is very hard for a smoker to give up smoking entirely due to the addictive nature of nicotine in the tobacco.
A problem with these articles is that their use does not provide a smoking experience.
A problem with the smokeless smoking article is the slow rising of the temperature to the optimum volatilization temperature region of tobacco, which is about 125 to 150° C. In addition, the smoking article requires that two separate chambers be combined to start the heat producing reaction.
A problem with the above-mentioned smoking articles is that the water which provides the exothermic reaction must be separated from the co-reacting compounds in the smoking articles.

example 1

[0075]The effect of the chemical compounds, starting materials, of the heat chamber on the exothermic reaction was tested in the experiments. Weight ratios of different starting materials were used in the tests to establish their effect on the heating rate, maximum temperature and temperature changes in the course of time. The heating tests were conducted with the reaction of potassium permanganate and iron in weight ratios of 30 / 70 and 70 / 30. A starting material mixture of 1.0 g was used in the tests. The reactions were conducted by positioning the starting materials in aluminum or glass tubes, whereupon the reaction was actuated by an electric fuse. The temperature was followed by a thermoelement attached to the tube.

[0076]The tubes fitted inside the fine cut tobacco part of a normal-size cigarette in such manner that space was left for the fine cut tobacco. The internal and external diameter and wall thickness of the aluminum and glass tubes were: Al 4.75 mm, 4.05 mm and 0.35 mm:...

example 2

[0082]The functionality of the smokeless smoking article was tested in the experiment. Insulated glass tube was used as the heat chamber structure. The structure was similar to that of Example 1. The thickness of the insulating layer formed by the aluminum foil and the fabric was 0.56 mm.

[0083]1.0 g of a mixture of potassium permanganate and iron (30 / 70) was introduced into the heat chamber.

[0084]The smoking article was produced by placing the heat chamber into a rolling machine with tobacco paper, filter and tobacco fine cut and by rolling the smoking article.

[0085]Reaction starting heat was introduced to the smoking article by a resistance wire which was heated by conducting electric current to the wire.

[0086]After the test, the smoking article was examined visually and it was observed that tar had been separated from the tobacco onto the paper surface. From the filter it was visible that the heat chamber reaction had separated ingredients from the fine cut tobacco. There was no o...

example 3

[0088]The test comprised analyzing the volatile elements of the smokeless smoking article according to the invention, a normal cigarette and a commercial smokeless smoking article: nicotine, carbon monoxide (CO) and tar. The smoking article according to Example 2 was used as the smokeless smoking article and Philip Morris “Gold” Marlboro as the normal cigarette. A smoking article according to Woodleaf Corporation brand Aēros was used as the commercial smokeless reference smoking article, which is based on a plastic tube that has been seamed at both ends and contains a matrix including nicotine and tobacco aroma. The smoker cuts off the ends of the plastic tube, and nicotine and tobacco aroma are released into the mouth and organs of the smoker when drawing in air through the tube.

[0089]Nicotine and tar components were determined by a GC-MS-apparatus and carbon dioxide by a GC-TDCapparatus. Two parallel assays were conducted for the cigarettes. The results of the smoking article acco...

Abstract

The invention relates to a smoking article comprising tobacco, suction resistance and a chemical heat source in conjunction with the tobacco. According to the invention, the heat source comprises a heat chamber and is activated by external excitation. The invention relates further to a method for producing the smoking article.

Description

FIELD OF THE INVENTION[0001]The invention relates to a smoking article as defined in the preamble of claim 1 and to a method for preparing a smoking article as defined in the preamble of claims 16 and 21.BACKGROUND OF THE INVENTION[0002]It is very hard for a smoker to give up smoking entirely due to the addictive nature of nicotine in the tobacco. An acceptable alternative has been to arrange the nicotine in some other form or some other way instead of smoking.[0003]Known articles used to replace cigarettes and / or to assist in giving up smoking include chewing gums, plasters, nasal sprays or lozenges with added nicotine.[0004]A problem with these articles is that their use does not provide a smoking experience. Smokers want to have the actual smoking experience, whereby they want e.g. to feel the taste of tobacco and smoke in their mouth.[0005]Patent publication U.S. Pat. No. 7,290,549 discloses a smokeless smoking article. The smoking article contains tobacco and a smokeless chemic...
