Definitions

• the present invention relates to an additional filter for cigarettes. More specifically, the invention concerns to an additional filter for cigarettes by which a system is realised to hold condensed and nicotine not held by the filters already provided in the standard available cigarettes.
• cigarettes sold on the market are provided with a filter to limit the intaking of nicotine and condensed by the consumer.
• these filters do not filter in a uniform way the smoke crossing the same.
• smoke passes through preferential paths. This effect involves that smoke intaken is not completely or sufficiently filtered and therefore the smoker is obliged to adsorb a higher amount of nicotine and condensed. The above can be demonstrated observing that the filters of smoked cigarettes are not evenly "stained".
• the object of the present invention is therefore that of providing a tool allowing to further filter the smoke inspired by the consumer, in such a way to limit the breathing in of nicotine and condensed.
• Another object of the invention is that of providing a disposable filter for smoking, that is cheap, not to raise the costs of the cigarettes.
• a cigarette filtering device characterised in that it is comprised of a cylinder to be put over the standard filter of the cigarette, and of at least a filtering material element.
• said cigarette filtering device provides a plurality of slots or openings on the cylinder wall.
• said at least one filtering material element is comprised of gauze or cotton.
• said at least one filtering material element is comprised of carbon. Still according to the present invention, said at least one filtering material element is comprised of salts.
• the colour of said cylinder is identical to the colour of the standard filter already provided in the commercial cigarettes, thus making the filter pleasant and discreet.
• said cylinder put on the standard filter of the cigarette, increases its consistency and thus makes it resistant to the compression due to the smoker lips. This makes unlikely the creation of preferential paths for the smoke flow inspired by the smoker.
• said cylinder is comprised of paper.
• said cylinder is comprised of plastic.
• said filter can be applied to filter-free cigarettes.
• FIG 1 shows an embodiment of the additional filter for cigarettes
• figure 2 shows the application mode of the filter on a cigarette
• figure 3 shows a cigarette introduced within the filter
• figure 4 shows a rear perspective view of the cigarette additional filter.
• additional filter 1 for cigarette comprised by a filtering material element 2, for example made up of gauze or cotton, and by a cylinder 3, for example made up of paper, that can be of the same colour of the filters provided on the commercial cigarettes, in such a way that when the filter is put on the cigarette, it is not noted. Further, being the cylinder 3 made up of not stiff material, the above mentioned phenomenon of motion of incisive teeth is avoided.
• Figure 2 shows the way in which the filter is applied on the cigarette 4. Particularly, beside the additional filter 1 , it can be noted the filtering material element 2 and the cylinder 3. Cigarette is introduced according to the direction A, introducing the filter within the cylinder 3.
• figure 3 shows the cigarette 4 after the application of the additional filter 1 .
• it can no more be viewed outside the filter of the cigarette 4, in fact it is completely covered by the cylinder 3 of the additional filter 1 .
• additional filter 1 is particularly pleasant and its use discreet.
• cylinder juxtaposes on the standard filter of the cigarette it is obtained that the total consistency of the point where the smoker lips are put is higher, thus making less probable the creation of preferential paths.
• the filtering element 2 it can be further seen the filtering element 2.
• Figure 4 shows the additional filter 1 for cigarette to which a plurality of slots 5 have been added on the lateral surface of the cilinder 3.
• the solution according to the present invention being inexpensive, further has the advantage of being directly applicable by the manufacturers during the production of the cigarette. Further, the additional filter described in the above can be easily removed by the smoker not wishing to use the same.
• a further advantage obtained by the solution according to the present invention, that must be underlined is the possibility of reducing the mortality, the National Health Service expenses, e.g. for periods in bed and medicines, as well as the probability that the smokers suffer of chronic bronchitis, emphysema, papillary neoplasia, etc.
• the present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
