Description

"SMOKING ARTICLE AND MANUFACTURING METHOD FOR A SMOKING ARTICLE"
Invention Field
The present invention relates to a smoking article comprising a space between a smoking material rod and a filtering element so as to form a chamber that is peripherally sealed by a wrapper that unites the smoking material rod to the filtering element, said wrapper having at least one ventilation opening.
State of the Art
Conventional ventilated cigarettes known in the art, which do not possess a space between a tobacco rod and a filtering element, usually provide cigarette smoke with variable characteristics. These variable characteristics may result in flavor alterations. These variable characteristics arise because the ventilation may vary in accordance with the conditions in which the cigarette is being smoked.
Documents PI8303783 and PI9001386 disclose cigarettes that possess a chamber located between two filters. Additionally, said documents disclose at least one ventilation opening in the wrapper that unites the tobacco rod to each filtering element in order to ventilate the chamber. In contrast with the objective of the present invention, said documents seek to optimize the smoke characteristics by means of better filtering of the same, without considering the standard deviation of the cigarette ventilation that could influence the smoke characteristics.
Document PI9401850-2 discloses a coaxial cigarette that provides a chamber between a coaxial tobacco rod and a filter to mix the smokes of the two types of tobacco present in the tobacco rod. The volume of said chamber is also adjustable in order to enable the change in smoke flavor perceived by the smoker. In contrast with the main objective of the present invention, in said document the chamber is designed to only mix the two types of smoke. In this document, there is also no consideration regarding the effect of the standard deviation of the cigarette ventilation.
No state of the art document reveals a ventilated smoking article consisting of a chamber located between a tobacco rod and a filter designed to homogenize the smoke in order to maintain the product flavor characteristics and simultaneously increase the diffusion of the smoke vapor phase.

Detailed Description of the Invention
The present invention will now be described in further detail in the following examples.
A suitable smoking article 1, which comprises a tobacco rod 2, at least one filtering element 3 and a wrapper 4, may have said wrapper fastened over the at least one filtering element and the tobacco rod so as to connect the same, the wrapper having at least one ventilation opening 5 (see figure 2).
The smoking article comprises a chamber 6 that is formed in the space located between the tobacco rod 2 and the filtering element 3, and is enclosed by the wrapper 4. Typically, the space measures between 2 and 5 mm, for example, between 2 and 3 mm (figure 2).
As shown in figure 2, the at least one ventilation opening 5 may be located over the chamber 6. However, acceptable results may also be obtained when the ventilation opening(s) is (are) located over the filtering element (figure 3).
In order to avoid that the smoke present in the extremity 8 of the tobacco rod 2 adjacent to the chamber 6 is deposited inside the same, part of the tobacco may be fastened on the liner 9 of the tobacco rod. Normally, this fixation is performed by means of an adhesive or by adjusting the quantity of tobacco on the extremities of the tobacco rod.
The smoking article may be manufactured by means of a manufacturing technique that comprises the steps of formation of a tobacco rod 2, formation of at least one filtering element 3 and the formation of at least one ventilation opening 5 in the wrapper 4; followed by the formation of a space between the tobacco rod 2 and the at least one filtering element 3; and connecting the tobacco rod 2 to the at least one filtering element 3 by means of fastening of a wrapper 4 over the same, such that a chamber 6 is formed by the space located between the tobacco rod and the at least one filtering element. Alternatively, suitable tobacco rods 2, at least one filtering element 3, and wrapper 4 with at least one ventilation opening 5 may be obtained commercially. Thus, the method may be carried out without the steps of forming such materials. The method may additionally comprise the step of fastening on the tobacco rod liner 9 the tobacco present on the extremity 8 of the tobacco rod 2 adjacent to the chamber 6. This fixation is preferably made by means of an adhesive or by means of the adjustment of the quantity of tobaccos located at the extremities of the tobacco rod.
The method of the present invention can be implemented on state of the art filter coupling machines, such as model MAX 100 manufactured by the Hauni Hamburg Company. The spacing between the tobacco rod 2 and the at least one filtering element 3 may be obtained by the installation of spacing guides 11 on a double closing drum 12 of a filter coupling machine 10 (figure 4).
The main benefit of the smoking article of the present invention is the reduction in the TIP ventilation standard deviation, conferring increased cigarette quality. TIP ventilation is the percentage measurement of the quantity of air that passes through the filter, promoting the dilution of the smoke resulting from the burning of the tobacco rod.
The secondary benefit of the present invention is the reduction of the concentration of carbon monoxide in the main smoke.
Table 1 below presents the experimental results observed in laboratory tests of the reduction in the ventilation standard deviation and of the reduction of carbon monoxide content obtained with the use of smoking articles of the present invention compared to commercial products with both high and low ventilation levels.
TABLE 1
In Table 1 , six cigarette alternatives were used, identified by numbers 135300 to 135305. Alternatives 135300 and 135301 refer to conventional cigarettes with ventilation over the filtering element and the remaining alternatives refer to the type of cigarette of the present invention that have a spacing of 2mm.
The expression mouth end represents the distance between the extremity of the filter closest to the smoker's mouth and the ventilation perforation line. TAR is the term used to describe the total substances present in the smoke excluding water and nicotine. Inhalations represent the number of times the cigarette is smoked by the smoking machine.
The measurement of the ventilation consists in the application of a vacuum to the cigarette extremity containing the filter, generating an airflow of 17.5 mUs through the cigarette (tobacco rod + ventilation). The airflow that passes through the cigarette tip and the tobacco rod are measured using a low-pressure transducer and these individual measurements of the cigarette are performed by adequately isolating the areas with coils lined with a latex glove. The result of ventilation is expressed as the total % of air that passes through the tobacco rod and the ventilation.
Alternatives 135305 and 135304 provide the ventilation openings positioned over the filtering element and alternatives 135302 and 135303 provide the ventilation openings over the space between the filtering element and the tobacco rod. As can be seen, the lowest ventilation standard deviation and variation coefficient was obtained for alternatives 135302 and 135303. However, all the alternatives cigarettes of the present invention provided a reduction of CO/TAR.
All publications mentioned in the above specification are herein incorporated by reference. Various modifications and variations of the described methods and system of the invention will be apparent to those skilled in the art without departing from the scope and spirit of the invention. Although the invention has been described in connection with specific preferred embodiments, it should be understood that the invention as claimed should not be unduly limited to such specific embodiments.
