Description

Smoking article and smoking article manufacturing method {SMOKING ARTICLE AND MANUFACTURING METHOD FOR A SMOKING ARTICLE}

The present invention relates to a smoking article comprising a space formed between the filter element and the smoking material rod to form a chamber circumferentially sealed by a wrapper coupling the smoking material rod to the filter element. As such, the wrapper has at least one ventilation opening.

In general, conventional ventilated cigarettes known in the art that do not have a space between the tobacco rod and the filter element change the properties of the cigarette smoke. This change in the characteristics of the cigarette smoke will result in a change in the tobacco aroma. This characteristic change occurs because the ventilation state changes depending on the conditions of smoking a cigarette.

Specifications (P18303783 and P19001386) describe cigarettes with a chamber located between two filters. In addition, the present specification discloses that at least one vent is installed in a wrapper that couples the tobacco rod to each filter element so that the chamber is vented. In contrast to the object of the present invention, the specification finds that it is possible to optimize the smoke characteristics using better filter means without considering the standard deviation of the cigarette ventilation that affects the smoke characteristics. Will.

The specification (P19401850-2) describes a coaxial cigarette with a chamber between the coaxial tobacco rod and the filter for mixing two types of tobacco smoke on the tobacco rod. In addition, the volume of the chamber can be adjusted such that a change in the smoke flavor inhaled by the smoker can be made. In contrast to the main object of the present invention, in the above specification, the chamber is designed only by mixing two types of smoke. The specification also makes no consideration of the effect of standard deviation of cigarette aeration.

The specification does not represent a vented smoking article with a chamber positioned between the filter and the tobacco rod designed to uniform the smoke to improve the diffusion of gaseous smoke while maintaining the tobacco aroma characteristics of the product.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described through preferred embodiments with reference to the accompanying drawings.

A suitable smoking article 1 consisting of a tobacco rod 2 and at least one filter element 3 and a wrapper 4 has a wrapper fixed thereon to which at least one filter element and the tobacco rod are connected, The wrapper has at least one vent 5 (see FIG. 2).

The smoking article has a chamber 6 formed in a space located between the tobacco rod 2 and the filter element 3 and surrounded by a wrapper 4. Typically the space is at a distance between 2 and 5 mm, for example between 2 and 3 mm (FIG. 2).

As shown in FIG. 2, at least one vent 5 is located above the chamber 6. However, positioning the vent (s) over the filter element also yields acceptable results (FIG. 3).

In order to prevent the smoke at the distal end 8 of the tobacco rod 2 near the chamber 6 from depositing on its inner side, a part of the tobacco is fixed on the liner 9 of the tobacco rod. Typically, this fixation is done by means of adhesion or by adjusting the amount of tobacco on the distal end of the tobacco rod.

The smoking article forms a tobacco rod 2, a wrapper 4 having at least one filter element 3 and at least one vent 5, the tobacco rod 2 and at least one filter element. (3) forming a space therebetween; And connecting the tobacco rod 2 to the at least one filter element 3 by means of fastening means of the wrapper 4, so that the chamber 6 is formed by a space located between the tobacco rod and the at least one filter element. It is manufactured by the manufacturing technique. Alternatively, a commercially available wrapper 4 having an appropriate tobacco rod 2, at least one filter element 3, and at least one vent 5 can be obtained. Thus, the method herein can be practiced without the process of forming such a material.

The method herein further comprises the step of securing the tobacco on the tobacco rod liner 9 at the distal end 8 of the tobacco rod 2 adjacent the chamber 6. This fixation preferably consists of adjusting the amount of tobacco located at the distal end of the tobacco rod or by means of an adhesive.

The method of the present invention can be implemented in art filter couplings such as, for example, the model MAX100 manufactured by the Hauni Hamburg Company. The separation space between the tobacco rod 2 and the at least one filter element 3 is made by installing the separation guide 11 in the double closing drum 12 of the filter coupling 10 (FIG. 4).

A major advantage obtained in smoking articles of the present invention is the reduction of the standard deviation of TIP breathing which improves the quality of cigarettes. TIP ventilation is a measure of the amount of air passing through the filter as a percentage, which dilutes the smoke produced by burning the tobacco rod.

Another advantage of the present invention is the dilution of the concentration of carbon monoxide in the main smoke.

Table 1 below shows the test results observed by laboratory tests with reduced aeration standard deviation values and reduced carbon monoxide content obtained using smoking articles of the present invention as compared to commercial products at both high and low aeration levels. .

In Table 1, six cigarettes designated by numbers 135300-135305 were selected and used. Reference numerals 135300 and 135301 refer to prior art cigarettes with vents on the filter elements and the remaining choices refer to the cigarette form of the invention spaced 2 mm apart.

The mouth end expression represents the distance between the filter end portion closest to the smoker's lips and the vent line. Tar is a term used to refer to all substances in smoke except water and nicotine. Inhalations represent the number of times a cigarette has been inhaled by a smoker.

Aeration measurements are made by applying a vacuum at the end of the cigarette with the filter, where 17.5 mL / s of air flow through the cigarette (tobacco rod + aeration) occurs. The air flow through the cigarette tip and the tobacco rod is measured using a low pressure transducer and this individual measurement of the cigarette appropriately covers an area with coils in line with the latex glove. It is done in isolation. Aeration results are expressed as the total percentage of air passing through the tobacco rod and the aeration.

Selection objects 135305 and 135304 have vents located above the filter elements and selection objects 135302 and 135303 are vented above the space between the filter element and the tobacco rod. As can be seen in Table 1, the minimum aeration standard deviation and variable coefficients were obtained for selections 135302 and 135303. As shown in Table 1 above, all selectable cigarettes of the present invention showed a reduction in CO / TAR.

All publications mentioned in the above specification are described herein by reference. Accordingly, those skilled in the art may variously modify and modify the above-described methods and systems of the present invention without departing from the scope and spirit of the present invention. That is, while the present invention has been described in connection with specific preferred embodiments, it is to be understood that the invention is not limited to the specific embodiments. Accordingly, the present invention is intended to embrace all such modifications and variations as may be made by those skilled in the art within the spirit of the appended claims.
