  The invention will be described in detail with reference to the following examples.

A preferred smoking article 1, ie a smoking article comprising a tobacco rod 2, at least one filter element 3 and a wrapper 4, the wrapper is fixed on the at least one filter element and the tobacco rod, the rod and filter And the wrapper has at least one ventilation opening 5 (see FIG. 2).

  The smoking article includes a chamber 6 in a space between the tobacco rod 2 and the filter element 3 and is surrounded by the wrapper 4. Usually, the length of the space is 2 to 5 mm, for example 2 to 3 mm (FIG. 2).

  As shown in FIG. 2, at least one ventilation opening 5 may be located on the chamber 6. However, acceptable results are obtained even if the ventilation opening is located on the filter element (FIG. 3).

  In order to prevent smoke passing through the end 8 of the tobacco rod 2 adjacent to the chamber 6 from accumulating in the chamber, a portion of the tobacco may be secured to the liner 9 of the tobacco rod. Normally, tobacco is secured using an adhesive or by adjusting the amount of tobacco at the end of the tobacco rod.

  The smoking article includes the steps of forming a tobacco rod 2, forming at least one filter element 3, and forming at least one ventilation opening 5 in the wrapper 4, and further comprising at least one tobacco rod 2 and Forming a space between the two filter elements 3 and joining the wrapper 4 to the tobacco rod 2 and at least one filter element 3 to join them together, and between the tobacco rod and the at least one filter element. And a step of forming a chamber by the provided space. Alternatively, a commercially available suitable tobacco rod 2, a wrapper 4 having at least one filter element 3 and at least one ventilation opening 5 may be used. Therefore, in this case, the smoking article can be manufactured without including the step of forming these materials.

  Further, the method of the present invention may include the step of securing the tobacco at the distal end 8 of the tobacco rod 2 adjacent to the chamber 6 to the tobacco rod liner 9. This may be done by adjusting the amount of tobacco located at the end of the adhesive or tobacco rod.

  The method of the present invention can be carried out using a conventional filter mounting device such as model number MAX100 manufactured by Hauni Hamburg. The space between the tobacco rod 2 and the at least one filter element 3 is obtained by providing space guides 11 on the two closing drums 12 of the filter mounting device 10 (FIG. 4).

  The main advantage of the smoking article of the present invention is to reduce the TIP ventilation standard deviation while improving the quality of the cigarette. TIP ventilation is a percentage measurement of the amount of air that passes through a filter that promotes the dilution of smoke caused by the burning of the tobacco rod.

  A second advantage of the present invention is that it reduces the concentration of carbon monoxide in mainstream smoke.

  Table 1 below shows laboratory tests of the reduction rate of ventilation standard deviation and the reduction rate of carbon monoxide content obtained using smoking articles of the present invention compared to commercial products of both high and low ventilation levels. The results are shown.

  In Table 1, six different cigarette products were used, each numbered 135300 to 135305. Products 135300 and 135301 are conventional cigarettes with ventilation holes on the filter element, and the remaining cigarette products are cigarette products of the present invention having a 2 mm long space.

  The term “mouth end” refers to the distance between the end of the filter closest to the smoker's mouth and the ventilation line. “TAR” is a term used to describe all substances present in smoke except water and nicotine. “Smoke absorption” represents the number of cigarettes smoked by the smoking device.

  The ventilation rate is measured by depressurizing the end of the cigarette containing the filter and generating an air flow of 17.5 mL / s through the cigarette (tobacco rod + ventilation hole). The airflow flowing through the end of the cigarette and through the tobacco rod is measured using a low pressure transducer, and individual measurements of the cigarette are made by separating the areas appropriately with a coil that is straightened with rubber gloves. It was. The ventilation measurement results represent the total amount of air that has passed through the tobacco rod and ventilation holes in%.

  Cigarette products 135305 and 135304 have ventilation openings on the filter element, and products 135302 and 135303 have ventilation openings on the space between the filter element and the tobacco rod. As is clear from the table, the ventilation standard deviation and coefficient of variation of products 135302 and 135303 were the smallest. However, all cigarettes of the present invention had a reduced CO / TAR ratio.
