Definitions

  • the present invention relates to a cigarette filter including a flavor capsule, and a cigarette.
  • a flavor capsule is incorporated in a cigarette filter and the flavor capsule is crushed in order to enjoy the flavor of the content liquid in smoking or in order to mask odor of a cigarette butt after the cigarette is extinguished (Jpn. Pat. Appln. KOKAI Publication No. 7-250665; Jpn. Pat. Appin. KOKAI Publication No. 2003-304856; Jpn. PCT National Publication No. 2007-520204; Jpn. PCT National Publication No. 2008-528053; and Jpn. PCT National Publication No. 2008-539717).
  • the details of the flavor capsule are described in, for example, Jpn. PCT National Publication No. 2008-546400.
  • Such cigarette filters including the flavor capsule have various problems.
  • FIG. 1( a ) shows a cigarette in which a tobacco rod 10 is connected to a filter 20 with a tipping paper 30 , wherein the tobacco rod 10 is prepared by wrapping a tobacco filler 11 with a cigarette paper 12 and the filter 20 is prepared by wrapping a filter plug 22 having a flavor capsule 21 embedded therein with a plug wrapping paper 23 .
  • the flavor capsule 21 has a structure in which content liquid 21 b is encapsulated with a shell 21 a.
  • the content liquid 21 b flowed out of the capsule is absorbed by the filter plug 22 , and thus the fluid is not soaked through the tipping paper 30 to the surface thereof, as shown in FIG. 1( b ).
  • Good usability, however, is not obtained because the flavor capsule 21 embedded in the filter plug 22 does not give a sense that the capsule is crushed.
  • a filter having a structure in which filter plugs are separated from each other and arranged through a cavity, with a flavor capsule provided in the cavity, can give the sense that the flavor capsule is crushed, and thus has a good usability.
  • FIG. 2( a ) shows a cigarette in which a tobacco rod 10 is connected to a filter 20 with a tipping paper 30 , wherein the tobacco rod 10 is prepared by wrapping a tobacco filler 11 with a cigarette paper 12 and the filter 20 has a structure that a flavor capsule 21 is provided in a cavity between two filter plugs 25 .
  • a material paper 26 is wrapped around each of the two filter plugs 25
  • a shaping paper 27 is wrapped around the periphery where both plugs are separated from each other and arranged through the cavity.
  • There is also a filter plug having either the material paper or the shaping paper, or having no material paper or shaping paper in the case of FIG. 1 , the plug has only the plug wrapping paper which serves as the material paper and the shaping paper).
  • the content liquid 21 b flowed out of the capsule is soaked through the tipping paper 30 to the surface thereof, as shown in FIG. 2B , because the shaping paper is generally made of a high-permeable material.
  • a liquid-impermeable tipping paper and/or filter wrapper a material paper, a shaping paper or a plug wrapping paper.
  • These materials are not limited to paper, and may be a wrapping material made of cellophane or plastic, or a composite material.
  • the shaping paper 27 is liquid-impermeable, the content liquid 21 b flowed out of the capsule moves toward the tobacco rod 10 or the mouthpiece end along the gap between the inside of the liquid-impermeable shaping paper 27 and the filter plugs 25 , as shown in FIG. 2( c ).
  • the liquid is finally passed through the tobacco filler 11 in the tobacco rod 10 , and is soaked through the tipping paper 30 to the cigarette paper 12 of the tobacco rod 10 .
  • the liquid which moves toward the mouthpiece end along the gap between the inside of the shaping paper 27 and the filter plug 25 is soaked to the end face of the filter plug 25 .
  • This disadvantage can be solved by coating the inside of the liquid-impermeable shaping paper 27 with wax or paste to fill the gap between the inside of the shaping paper 27 and the filter plug 25 , thereby preventing the migration of the content liquid 21 b.
  • the residue of wax or paste adheres to a filter making machine, and thus it is difficult to perform mass production.
  • the object of the present invention is to provide a cigarette filter including a flavor capsule, capable of preventing soakage of the content liquid to the surface of the tipping paper, the cigarette paper of the tobacco rod and the filter mouthpiece end face when it is used, without causing trouble in the filter production; and a cigarette including this cigarette filter.

  • a cigarette comprising: a tobacco rod; and the above cigarette.
  • the cigarette filter and the cigarette of the present invention can prevent the soakage of the content liquid to the surface of the tipping paper, the cigarette paper of the tobacco rod and the filter mouthpiece end face when it is used, by adding a thickener to the content liquid in the flavor capsule to adjust a viscosity of the content liquid to 30 mPa ⁇ s or more.
