FR2462110A1 - Cigarette with graded tobacco mixture - has strong tobacco at lighted end for initial smoking and weaker tobacco at filter end - Google Patents

Abstract

The cigarette comprises a filter (2) at one end and a column (1) of tobacco enclosed with paper wrapping (3). At the end farthest from the filter, that is, the lighted end, the column of tobacco is made up of a strong mixture (4) which is rich in nicotine and/or tar. This provides initial satisfaction. The remainder of the cigarette contains one or more less strong tobacco mixtures (5), to provide smoking satisfaction without the risks inherent in high nicotine and tar levels. The ratio between the stronger and less strong tobaccos is approximately 1/3 to 2/3 respectively.

Description

 The present invention relates to the field of manufacturing cigarettes, and relates to a cigarette with several tobaccos.

 Currently, cigarettes are generally formed by a cylindrical column of tobacco wrapped in a sheet of paper. During their combustion, these cigarettes change their taste and become stronger and stronger, because nicotine and / or tar accumulate near the end put in the mouth by the consumer, if necessary, near the filter, and thus, the last puffs of a cigarette are much more loaded with harmful products than the first.

 In addition, many smokers mostly experience satisfaction with the first puffs of a cigarette, especially because of the richness in nicotine and / or tar, and do not smoke the rest of the cigarette any more than out of habit. These smokers could, after the first puffs, also be satisfied with a cigarette less rich in nicotine and / or tar.

 Various methods have been proposed to overcome these drawbacks, namely the addition of tobacco products intended to regulate the combustion, or even perforations of the paper at the end of the mouth, to allow a supply of air. more important at the end of combustion, or a mixture of tobacco substitutes, in order to partially neutralize its effects.

 These processes however have the effect of considerably increasing the cost price of cigarettes as well as neutralizing in a more or less significant manner, in addition to its harmful effects, also the taste of tobacco.

 The present invention aims to overcome these drawbacks.

 It has, in fact, for its object a cigarette constituted by a column of tobacco rolled up in a sheet of paper, and possibly provided with a filter at the end placed in the mouth, characterized in that the column of tobacco is constituted by at minus two tobacco mixtures, i.e. a mixture of strong tobacco, that is to say richer in nicotine and / or tar, and a mixture of tobacco less strong, that is to say less rich in nicotine and / or in tar, the mixture of weaker tobacco being disposed on the side of the end placed in the mouth, or of the filter.

 The invention will be better understood thanks to the description below, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawing, in which FIG. 1 is a view in section, on a larger scale, of a cigarette according to the invention, and Figure 2 is a view similar to that of Figure 1 of an alternative embodiment of the invention.

your cigarette shown in the accompanying drawing is essentially constituted by a tobacco column 1, possibly extended by a filter 2, and by a sheet of paper 3 wrapped around the assembly. The tobacco column 1 is constituted, in accordance with the invention, by two tobacco mixtures, namely a mixture of strong tobacco 4, and a mixture of weaker tobacco 5. The mixture of weaker tobacco 5 is placed on the side of the filter 2, between the mixture of strong tobacco 4 and said filter 2.

 The proportion of strong tobacco mixture 4, that is to say mixture richer in nicotine and / or tar, and less strong tobacco mixture 5, that is to say mixture less rich in nicotine and / or tar, can be adjusted during manufacture, depending on the type of cigarette desired. By way of example, this proportion may be 1/3 of a mixture of strong tobacco for 2/3 of a mixture of weaker tobacco.

When consuming a cigarette according to the invention, the smoker will have at the beginning, by the combustion of the mixture of strong tobacco, the satisfaction produced by the combustion of tobacco richer in nicotine and / or in tar After this combustion, which satisfies the initial need, the smoker is satisfied with a mixture of tobacco less rich in nicotine and / or tar.

it is also possible to provide more than two tobacco mixtures for a cigarette, by staging these said mixtures from the strongest, that is to say from the richest in nicotine and / or in tar, towards the weakest, that is that is to say the least rich in nicotine and / or in tar, in the direction of the filter or of the excess placed in the mouth, this staggering being able to be achieved by juxtaposition of homogeneous sections, or by a heterogeneous mixture forming a decreasing increasing rate nicotine and / or tar. Such an example of cigarette construction is shown in FIG. 2, in which the tobacco column 1 ′ has at its end opposite the filter 2 ′ the strongest tobacco mixture, this mixture being progressively weaker, that is to say less rich in nicotine and / or tar, in the direction of said filter 2 t -
Such a cigarette constitution ensures consistency of taste, thanks to the fact that the nicotine and / or the tar contained in the smoke resulting from the combustion of strong tobacco are partially retained by the particles of the weaker tobacco, so that the first smoke undergoes double filtration, these products being partially returned during the combustion of the less strong tobacco, the taste of which is thus enhanced.

 Of course, the invention is not limited to the embodiments described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of cigarettes, in particular of the tobacco mixtures employed, without thereby departing from the scope of protection of the invention.

Claims (2)

-RENDENDATIONS-  1 Cigarette, essentially constituted by a column of tobacco rolled up in a sheet of paper, and optionally provided with a filter at the end placed in the mouth, characterized in that the tobacco column consists of at least two mixtures of tobacco, namely a mixture of strong tobacco, that is to say rich in nicotine and / or in tar, and a mixture of less strong tobacco, that is to say less rich in nicotine and / or in tar, the mixture of less strong tobacco being placed on the side of the mouthpiece end, or of the filter, and the proportion of strong tobacco and less strong tobacco being a function of the type of cigarette desired. 2 Cigarette according to claim 1, characterized in that the tobacco column comprises several tobacco mixtures stepped from the strongest, that is to say the richest in nicotine and / or tar, towards the weakest, it that is to say the least rich in nicotine and / or in tar, in the direction of the filter or the end placed in the mouth, this spreading can be achieved by juxtaposition of homogeneous sections, or by a heterogeneous mixture forming a decreasing gradient nicotine and / or tar levels.
