Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a novel cigarette structure in which the tobacco in the cigarette is modified to provide improved smoking characteristics.

[Conventional technology]

Two or more types of tobacco raw materials
It is well known, for example, in U.S. Pat. describes a cigarette occupying an outer ring surrounding this core.

It is also well known that a large portion of the tobacco smoke that enters a smoker's mouth comes from the burning of the tobacco in the circular outer wrapper of the cigarette. It is said that about 80% by weight of the smoke that enters a smoker's mouth comes from only about 50% by weight of the smoke in the cigarette.

Furthermore, when a cigarette is first lit in the evening, the smoke resulting from the combustion of the tobacco material over the entire cross-sectional area of the cigarette is drawn into the smoker's mouth, rather than primarily from the combustion of the annular material. It is also well known that smokers experience different tastes when lit because of the

Oo ■ (filed on May 13, 2013), a material equivalent to a ring material is added to the lighting end of a cigarette, so that when the cigarette is lit, the smoke that reaches the smoker's mouth is mainly a ring material. A cigarette made of strip material is disclosed, to which reference is made in the present invention for this description.

In this way, no or little change in the taste of the tobacco smoke will be perceptible to the smoker as combustion progresses from ignition to continuous smoking.

A co-pending U.S. application filed at the same time as the above-mentioned application by the applicant of the present invention, titled "Linear Layer Cigarettes," contains the same or similar amount of tar, but −/Increments i− with relatively high tar ratio
A novel cigarette structure is described in which two outer layers of tobacco leaf material are sandwiched between an intermediate layer of chopped tobacco leaf material having a relatively low flavor/tar ratio, thus reducing the This application, which achieves uniformity across the length of flavor and tar, is also incorporated herein by reference.

As described therein, one method of implementation is to cut the high-flavor tobacco from one end of the cigarette, place it back into the cigarette making machine, and place it in the 2783 layer on the opposite side of the rod. put it inside. Techniques may also be employed to create a denser end to increase the amount of high flavor tobacco at the end of the cigarette.

The conventional end densification method involves trimming with a pocket or hatch to cut the thinner part of the rod when it passes through the trimmer. This includes using a rotary cutter. Without changing the height of the trimmed portion of the tobacco, the portion of the tobacco immediately in front of the trimming point may be compressed, for example with a rotary compression device having lobes that mechanically compress the tobacco onto the rod carrying surface.

[Problem that the invention seeks to solve]

The present invention provides a novel cigarette made from a blend of two tobaccos which, when smoked, delivers a uniform flare along its length. Additionally, the present invention provides a simple method for manufacturing cigarette filler rods made of different blends of tobacco.

[Means for solving problems]

In the present invention, using conventional tobacco making and making machinery, a first blend of chopped tobacco leaf material having a first flake/tar ratio is placed on the left hand side of the hopper (or on the rod forming and conveying surface). and a second blend of chopped tobacco flake material with an even higher flavor/tar ratio on the right-hand side of the conch (or on the rod-forming surface). The filling rod is then placed on the opposite side of the rod, on the side of the conch that provides the tobacco, and then creates a shower of tobacco leaf pieces from such a conch, the filling rod is placed on the rod-forming and conveying surface. can be produced from this shower by passing it across it. The higher Flay ζ- tobacco is trimmed from the filling rod and the trimmed tobacco is returned to the left hand side of the hopper to become part of the first blend. A high-density termination device is used to increase the amount of high-flare tobacco at the end of the cigarette.

The cigarette thus obtained contains an increasing amount of high frayed ζ-ta/S at its extremity, while having a constant concentration of high frayed 2-ta/s on its outer side. It is. The presence of an increased amount of high-flavor gas at the lighting end increases the initial flavor shock to the smoker,
A strip of high-flavor tobacco on the other exterior side increases the longitudinal flare by the same amount without increasing the amount of tar in the smoke. Therefore, it is also possible to reduce the amount of tar by reducing the sacrifice of flake 2-.

One major advantage of the cigarettes of the present invention is that they can be produced on conventional roll/two-roll machines without any equipment changes, and simply produce two types of cigarettes instead of one type of blend. By simply feeding Brenr into a hopper in one location, cigarettes with significantly improved smoking characteristics can be produced.

To intensify the favorable effect of the densified end of the high Freno 9-Tanoko and further increase the uniformity of the smoking characteristics, increase the length of the densified end, e.g. the perimeter of the notch in the trimming wheel. You can make it longer by doing this.

While smoking a cigarette, the amount of flavor compounds in the smoke is
The last puff typically contains about three times as much Flay 2-component as the first puff, as it tends to increase with puffing. Rolling evening
It is also possible to vary the relative proportions of the cross-section of the cigarette in the layers in the filler rod over the length of the cigarette, thereby modifying the smoking characteristics along the length of the cigarette. becomes uniform.

The method of manufacturing cigarettes described in this invention can also be combined with the Nierrejung process described in the applicant's above-mentioned US patent application Ser. No. 862.702.

The cigarette may then be trimmed on both sides to provide a cigarette with well-adjusted sides.

In the present invention, the filling lot may be further modified to further distribute the flavor components evenly. In the above-described densifying terminal devices that use lobes to mechanically compress tobacco into a tape, the shape of the lobes can be adjusted accordingly to vary the amount of tobacco trimmed as the filler rod moves past the cutter. It is also possible to provide one. In this way, the amount of high flavor tobacco can be determined as a function of the distance along the final cigarette, adjusting the amount of high flavor tobacco along the length of the cigarette. be able to. By adjusting the amount of high-flare tobacco in the cross section of the cigarette roll P in each section, although not necessarily for all sections of the length of the cigarette, the smoker can , you will be able to inhale smoke with a more even flavor. Additionally, by preparing separate blends for the eight high-flare powders located on one side of the filler lot 12, the flavor and tar characteristics of the smoke can be controlled, and the overall quality of the cigarette can be adjusted. Considerable diversity in smoking characteristics can be provided.

Tobacco leaf blends with different flavor/tar ratios
To prepare tobacco leaves from different parts of the tobacco plant can be selected.

Generally, leaves from the upper part of the tobacco plant have a higher flake/tar ratio than leaves from the lower part of the tobacco plant.

When blending tobacco for use in rolled tanomako, the high flavor /
While the tar-ratio tobacco is kept as a separate blend, some of these high-flare tobaccos can be converted to low-flare tobacco by recirculating the trimmed tobacco as described above. /tar ratio blend.

In summary, the present invention provides a novel arrangement of glue in cigarettes that can achieve considerable diversity and uniformity of smoking characteristics. Additionally, the present invention provides a method for making such cigarettes by making simple and effective modifications to conventional cigarette making operations. It goes without saying that various improvements can be made within the scope of the present invention.
