Definitions

  • the present invention relates to a filter cigarette which has a low amount of tar and to which menthol is added.
  • Methods involve adjusting the inflow amount of air in filter cigarettes by providing ventilation holes in the filter, for the purpose of adjusting components in smoke during smoking.
  • Adjusting the draw resistance of a filter in accordance with the amount of a component in smoke is a known feature in ordinary filter cigarettes.
  • Patent Document 1 discloses a filter cigarette having a filter that has a draw resistance of 50 mmH 2 O/100 mm (corresponding to 13.5 mmH 2 O/27 mm) and a ventilation ratio in the range of 20 to 80%.
  • Patent Document 2 discloses a filter cigarette having two filter segments and having the feature of adjusting the two filter segments, so that one of the two has a greater draw resistance than the other, and adjusting to a predetermined range of the amount of air inflow from tipping paper with which the filter is wrapped, whereby sufficient smoking satisfaction is afforded as a result, despite lowering of the concentration of nicotine and tar in mainstream smoke.
  • Patent Document 3 discloses, as a method for adding various menthol flavors to a filter, a method that involves adding, to acetate tow, a flavoring liquid resulting from dissolving or dispersing menthol in a plasticizer that is used in the production process of the filter.
  • Patent Document 4 discloses means for causing menthol to be held in a flavor carrier and preventing a decrease in the amount of menthol with the passage of days.
  • Patent Document 5 illustrates means for preventing a decrease in the amount of menthol with the passage of days, by using a sheet having aroma retention properties.
  • Patent Document 6 discloses a method for producing a filter, to which addition and sorption of a flavor are implemented beforehand, in order to prevent the drop in a menthol amount in smoke with the passage of days, or the like.
  • the amount of menthol in smoke during smoking of a filter cigarette having menthol is adjusted by way of the flavoring amount of menthol that is added to the cigarette.
  • the amount of flavor added to the cigarette is simply increased, the menthol having coloring matter of tobacco dissolved therein seeps into the cigarette paper that covers shredded tobacco of the cigarette, and becomes adhered to the cigarette paper, thereby giving rise to an undesirable external appearance.
  • the amount of menthol in smoke increases in proportion to the tar amount in the cigarette, and hence the amount of menthol in smoke decreases ordinarily in so-called low tar cigarettes having a tar amount of 5 mg or less.
  • the only countermeasure herein is a method that involves adding to the cigarette the largest possible amount of menthol that does not give rise to problems of restrictor element spotting and the like.
  • Patent Document 4 is problematic in that, for instance, costs are higher on account of the use of a flavor carrier, and in that suitability for production is complex and difficult given the need for providing separately a carrier addition process, in a case where the carrier is added to the interior of the filter.
  • Patent Document 6 describes a method for increasing the menthol addition amount to a filter, as a method for increasing the amount of menthol in smoke.
  • the method requires selecting a plasticizer in which menthol dissolves, in order to add the menthol to the plasticizer of the filter.
  • Menthol is poorly soluble in triacetin, which is ordinarily used as a plasticizer, and accordingly it is necessary to prepare a flavoring liquid by dissolving menthol through mixing with a solvent such as polyethylene glycol.
  • the present invention succeeds in affording a higher amount of menthol in smoke during smoking and in providing a low tar menthol cigarette exhibiting little change in the amount of menthol in smoke after storage.
  • a low tar menthol cigarette having a tobacco rod portion and a filter portion wrapped with tipping paper, the cigarette having a tar amount of 5 mg or less, wherein the filter portion includes a single segment made up of cellulose acetate tow, an draw resistance of the filter portion is 25 to 80 mmH 2 O/27 mm and a ventilation ratio of air inflow through ventilation holes pierced in the tipping paper is 55% or higher, and menthol is added to the filter portion, and arrived at the present invention on the basis of that finding.
  • the present invention is as follows.
  • the low tar menthol cigarette of the present invention affords a higher amount of menthol in smoke during smoking and exhibits little change in the amount of menthol in smoke after storage.
  • the low tar menthol cigarette of the present invention is a filter cigarette having a tobacco rod portion and a filter portion wrapped with tipping paper, wherein the filter portion has a single segment made up of cellulose acetate tow; the draw resistance of the filter portion is 25 to 80 mmH 2 O/27 mm and the ventilation ratio of air inflow through ventilation holes pierced in the tipping paper is 55% or higher; and menthol is added to the filter portion.
  • Known implementations can be used in the tobacco rod.
  • Known types of shredded tobacco for cigarettes can be used without particular limitations.
  • the shredded tobacco is then wrapped with cigarette paper to yield the tobacco rod.
  • a restrictor element such as capsules or orifices may be disposed inside the tobacco rod for the purpose of adjusting the draw resistance of the low tar menthol cigarette (filter cigarette).
  • the filter portion that makes up the low tar menthol cigarette of the present invention is wrapped with tipping paper.
  • the tipping paper that can be used in the present invention is not particularly limited, and may be air-impermeable tipping paper.
  • An air inflow means made up of a plurality of perforations (ventilation holes) pierced along the circumferential direction of the filter to be wrapped is provided in the tipping paper; as a result, it becomes possible to adjust the ventilation ratio of air inflow through the ventilation holes that are pierced in the tipping paper of the low tar menthol cigarette.
  • the perforations include, for instance, providing the perforations in the form of one or more rows in the circumferential direction of the filter.
  • the air permeability of the tipping paper having formed therein a plurality of pierced perforations ranges ordinarily from 100 to 7000 C. U.
  • C. U. denotes flow rate (mL (0.001 L)) through 1 cm 2 (100 mm 2 ) of tipping paper in 1 minute (60 seconds) for a differential pressure of 100 mmH 2 O (980.665 Pa).
  • the ventilation ratio of air inflow of the low tar menthol cigarette of the present invention is 55% or higher.
  • the ventilation ratio is preferably 61% or higher, more preferably 70% or higher. Under such a ventilation ratio the smoker can feel more intensely the flavor of menthol.
  • the draw resistance of the filter for such a ventilation ratio is 80 mmH 2 O/27 mm or smaller.
  • the ventilation ratio of air inflow in the present invention denotes the ratio, in percentage, of the flow rate of air taken up into the filter cigarette, through the tipping paper (having an air inflow means), with respect to the flow rate of air at the mouth end, upon inhalation of the filter cigarette (product) at a standard flow rate of 17.5 cm 3 /sec.
  • the ventilation ratio of air inflow can be adjusted for instance through modification of the size, count, and number of rows of the above plurality of perforations, or through modification of air permeability by changing the material of the tipping paper.
  • the position of the perforations may be set at 12 to 20 mm from the mouth end.
  • the draw resistance of the filter portion denotes, in the present invention, a differential pressure PD (mmH 2 O) at the filter portion upon inhalation at a flow rate of 17.5 cm 3 /sec, from one end of the filter portion having the side face thereof covered with air-impermeable rubber so as to preclude inflow of air.
  • PD differential pressure
  • the filter portion that makes up the low tar menthol cigarette of the present invention may include a single segment.
  • the filter portion that is used in the filter cigarette of the present invention has one single segment made up of cellulose acetate tow.
  • the segment made up of cellulose acetate tow may have a restrictor element such as capsules, orifices or the like.
  • the draw resistance of the filter portion of the low tar menthol cigarette of the present invention takes as a reference the draw resistance of the filter itself not including the restrictor element.
  • the shapes of the capsules and orifices are not particularly limited, and known shapes may be resorted to herein.
  • the material that constitutes the single segment made up of the cellulose acetate tow of the filter portion used in the present invention is cellulose acetate.
  • cellulose acetate fibers that make up cellulose acetate tow include, for instance, fibers having a single-fiber fineness of about 1.0 to 8.0 denier and a total fineness of 15000 to 70000 denier.
  • the cross-sectional shape of the fibers include, for instance, circular, oval, Y-shaped, X-shaped and I-shaped cross-sections.
  • the filter interior include, for instance, an interior uniformly filled with cellulose acetate tow.
  • the draw resistance of the filter portion used in the low tar menthol cigarette of the present invention is of 25 to 80 mmH 2 O/27 mm.
  • the "27 mm" used in the units of draw resistance denotes the lengthspotting of the filter portion in the longitudinal direction.
  • a draw resistance of the filter of 25 mmH 2 O/27 mm or greater allows for sufficient filtering of smoke during smoking.
  • a draw resistance of the filter of 80 mmH 2 O/27 mm or smaller allows efficiently reducing the filtration rate of menthol without incurring excessive filtering of smoke during smoking.
  • the density of the filter is low, and hence menthol is not adsorbed readily during storage.
  • the menthol concentration in the smoke can be kept within a desired range when the draw resistance of the filter lies within the above range and when the ventilation ratio of the filter cigarette is set to lie within the predetermined range described below. This effect can be made yet more prominent in a case where the draw resistance of the filter portion is 25 to 50 mmH 2 O/27 mm and the ventilation ratio of air inflow is 70% or higher.
  • the draw resistance of the filter can be adjusted for instance by selecting properly the total fineness (filling amount) and the single-fiber fineness of the cellulose acetate tow. Specifically, the draw resistance can be reduced when the specifications of the cellulose acetate tow involve increasing the single-fiber fineness and reducing the total fineness.
  • Examples of the value of tow weight used in the filter, with the length of the filter set to 27 mm, include for instance 0.100 to 0.200 g; herein, the density of the filter can be adjusted by regulating the weight within this range.
  • implementations of draw resistance per one low tar menthol cigarette include an draw resistance in the range of about 20 to 70 mmH 2 O, in the case where no restrictor element is present.
  • draw resistance of one filter cigarette denotes a differential pressure PD (mmH 2 O) per filter cigarette, including the effect of ventilation, upon inhalation at a flow rate of 17.5 cm 3 /sec from one end of the filter. That is, the draw resistance of one filter cigarette is the draw resistance measured in the product state in which the tobacco rod portion and the filter portion are connected.

  • the tar amount of the low tar menthol cigarette of the present invention is 5 mg or less.
  • the term tar amount in the present invention refers to the amount of tar inhaled by the smoker during smoking.
  • the composition of the shredded tobacco in the tobacco rod In order to bring the tar amount to 5 mg or less, i.e. to bring the target tar amount to 5 mg or less, there can be modified the composition of the shredded tobacco in the tobacco rod, the draw resistance in the filter portion, or the ventilation ratio of the low tar menthol cigarette.
  • Implementations of a tar amount of 5 mg or less include adjusting the tar amount as appropriate to lie for instance in the range of 0.5 to 5 mg.
  • the low tar menthol cigarette of the present invention allows conveying a sufficient flavor feel of menthol to the smoker, even for such a low tar amount.
  • the measurement of the tar amount in the filter cigarette involves for instance one measurement per 20 cigarettes, in accordance with ISO smoking conditions (ISO 4387). Gas chromatography is used in the measurements.

This can be ascribed to differences in filtration rate between tar and menthol, in the relationship between the draw resistance and the ventilation ratio of the filter.
  • the amount of menthol that condenses / adsorbs onto the tow fibers of the filter decreases due to the smallness of the total amount of tow, in addition to physical smoke filtration phenomena inside the filter, and there increase the amount of menthol in smoke and the M/T ratio.
