Definitions

  • the present invention relates to a cigarette comprising a cigarette filter including a flavor capsule.
  • Patent Documents 1 and 2 Conventionally, a flavor capsule is incorporated in a cigarette filter, and the flavor capsule is crushed to enjoy the flavor of the content liquid in smoking or to mask the odor of the cigarette butt after extinguishment (Patent Documents 1 and 2). Details of the flavor capsule are described in, for example, Patent Document 3.
  • a tipping paper or a plug wrapping paper plays a role in concealing the joint between the filter and the tobacco rod or concealing the color of tar adhered to the filter material from a smoker. Accordingly, an opaque paper is generally used. In the case of a charcoal filter, an opaque tipping paper or plug wrapping paper also plays a role in concealing the color of activated carbon, in addition to the above role.
  • Patent Document 4 discloses that transparent materials are used as a tipping paper and a plug wrapping paper in order to visualize the inside of a filter and that an opaque coating is applied to a part of the tipping paper to impart a concealing function.
  • Patent Document 4 exemplifies polypropylene, polyvinyl chloride, a cellulose acetate film, polyethylene terephthalate, polyethylene oxide, polyethylene, cellophane, Natureflex (registered trademark), and polyacetic acid as the transparent materials.
  • Patent Document 4 discloses that the tipping paper and the plug wrapping paper may be colored to be semi-transparent for the purpose of providing an esthetic effect to the filter as long as the inside of the filter can be visualized.
  • Patent Document 5 discloses that transparent film materials are used as a tipping paper or a filter wrapping paper in order to visually recognize flavor particles in the filter, and exemplifies polypropylene, polyvinyl chloride, and a cellulose acetate film as transparent film materials.
  • Patent Document 6 discloses that transparent materials are used as a tipping paper or a plug wrapping paper in order to visualize extraction effects of a harmful substance.
  • the present inventors have focused on the problems that when a cigarette including a flavor capsule in a filter portion is wrapped with an opaque plug wrapping paper or an opaque tipping paper, it is hard for a smoker to find the position of the flavor capsule in crushing the capsule and it is impossible for a smoker to observe that the capsule content liquid is spread in the filter after crushing the capsule.
  • the above concealing function i.e., a function to conceal the joint between the filter and the tobacco rod or conceal the color of tar adhered to the filter material
  • the transparent tipping paper and the transparent plug wrapping paper are used to visualize the flavor capsule, the amount of the capsule content liquid is extremely small and thus it is difficult to visually recognize that it is sufficiently spread in the cavity, though it is possible to recognize the breakage of the capsule.
  • an object of the present invention is to provide a cigarette comprising a tipping paper and a plug wrapping paper, wherein
  • a cigarette including a flavor capsule it has been intended not to form a stain of the capsule content liquid released by breakage of the capsule on the plug wrapping paper or the tipping paper.
  • an oilproof paper is preferably used as the plug wrapping paper.
  • the present inventors have attached the capsule content liquid to a semi-transparent plug wrapping paper so as to intentionally form a highly transparent stain on the plug wrapping paper and completed the present invention.
  • a cigarette comprising:
  • FIGS. 1A and 1B are cross-sectional views showing a part of cigarettes of the present invention.
  • FIG. 1A shows the cigarette before crushing a flavor capsule 23
  • FIG. 1B shows the cigarette after crushing the flavor capsule 23.
  • the cigarettes shown in FIGS. 1A and 1B comprise a tobacco rod 10 and a filter 20 where the flavor capsule 23 is contained in a cavity defined by two filter plugs 21a and 21b and a plug wrapping paper 22.
  • the tobacco rod 10 and the filter 20 are connected by the tipping paper 30.
  • the cigarettes shown in FIGS. 1A and 1B have a cylindrical shape as a whole, similarly to a usual filter-tipped cigarette.
  • the tobacco rod 10 is formed of a tobacco filler 11 and a cigarette paper 12 wrapped around the tobacco filler, similarly to a usual cigarette, and has, for example, a diameter of 5 to 10 mm and a length of 40 to 80 mm.
  • the filter 20 includes the filter plugs 21a and 21b spaced apart from each other via a cavity, the plug wrapping paper 22 wrapped around the filter plugs 21a and 21b to form a cavity between the filter plugs, and the flavor capsule 23 contained in the cavity between the filter plugs and encapsulating a flavor-containing content liquid in a shell.
  • the filter 20 has almost the same diameter as that of the tobacco rod 10 and may have, for example, a length of 15 to 40 mm, similarly to a usual filter.
  • N filter plugs (N is an integer more than or equal to 2) may be arranged via (N-1) cavities.
  • N is from 2 to 4, preferably from 2 to 3, more preferably 2.
  • the filter plugs 21a and 21b may be formed of a fibrous filter material such as a cellulose acetate fiber, similarly to a usual filter-tipped cigarette.
  • the filter plugs may be formed of only the fibrous filter material or may be formed of the fibrous filter material and a material paper wrapped around the fibrous filter material.
  • the filter plug 21a at the side of cut tobacco and the filter plug 21b at the side of a mouthpiece may have the same material and structure or may have different materials and structures.
  • the plug wrapping paper 22 is wrapped around the two filter plugs 21. As a result, it forms a cavity together with the two filter plugs 21a and 21b.
  • the plug wrapping paper 22 is semi-transparent and has an opacity level such that the flavor capsule 23 located in the cavity can be visually recognized. That is, the plug wrapping paper 22 has an opacity level such that the position of the flavor capsule can be visually recognized by a smoker in crushing the flavor capsule in the filter.
  • the plug wrapping paper 22 has a concealing function to keep an internal structure of the filter concealed. Further, when the capsule content liquid released by breakage of the flavor capsule is adhered to the plug wrapping paper 22, the opacity of the plug wrapping paper 22 is decreased and the visually recognizable level of the flavor capsule is increased.
  • the transparency of the plug wrapping paper 22 is increased in a position where the capsule content liquid is adhered.
  • the outline of the broken flavor capsule can be clearly observed.
  • the expression "visually recognizable level is increased” means that the outline of the broken flavor capsule can be clearly observed. Specifically, it means that the evaluation score is increased according to the evaluation criteria described in Table 1 below. As a result, the smoker can visually recognize that the capsule content liquid is spread in the cavity.
  • the capsule content liquid is adhered to a semi-transparent plug wrapping paper so as to form a highly transparent stain on the plug wrapping paper.
  • the spread stain enables the capsule content liquid spread in the cavity to be visually recognized. As a result, the smoker can enjoy the flavor after visually recognizing that the capsule content liquid is sufficiently spread in the cavity.
  • the plug wrapping paper 22 specifically satisfies the following three requirements in the present invention.
  • the tipping paper is preferably transparent.
  • the opacity is generally from 0.5 to 3%.

That is, the plug wrapping paper and a test paper are laminated to form a laminated paper, and the opacity of the laminated paper is measured from the side of the test paper; the capsule content liquid is dropped to the laminated paper from the side of the plug wrapping paper, and the opacity of the laminated paper is measured from the side of the test paper; the opacity after dropping the capsule content liquid is subtracted from the opacity before dropping the capsule content liquid to obtain the difference in the opacity; and in the case where the difference is 10% or less, the plug wrapping paper is evaluated as having impermeability to the capsule content liquid, and in the case where the difference exceeds 10%, the plug wrapping paper is evaluated as not having impermeability to the capsule content liquid (see Example 2 below).
  • the expression "having impermeability” used herein encompasses not only the case of having complete impermeability, but also the case of having impermeability and very slight permeability (see Table 3 below).
  • the opacity is also measured in accordance with JIS P8138A (1976).
  • the "test paper” used herein is an opaque paper having a function as a filter paper which can absorb a liquid when the liquid permeates the plug wrapping paper.
  • a paper having an opacity of 80 or more and a thickness of 33 to 53 ⁇ m can be used. Examples thereof include 37 White Stencil Paper (Nippon Paper Papylia Co., Ltd.).

  • the opacity thus measured is 70% or less, preferably from 5 to 70%, more preferably from 10 to 40%, still more preferably from 15 to 40%. When the opacity exceeds 70%, it is difficult to visually recognize the flavor capsule through the plug wrapping paper and the tipping paper.
  • the laminated paper formed of the plug wrapping paper and the tipping paper satisfies the requirement (3) as follows. That is, the plug wrapping paper and the tipping paper are laminated to form a laminated paper, and the opacity of the laminated paper is measured from the side of the tipping paper; the capsule content liquid is dropped to the laminated paper from the side of the plug wrapping paper, and the opacity of the laminated paper is measured from the side of the tipping paper; and the opacity after dropping the capsule content liquid is subtracted from the opacity before dropping the capsule content liquid to obtain the difference in the opacity (see Example 3 below).
  • the opacity is also measured in accordance with JIS P8138A (1976).
  • the difference in the opacity thus obtained is 5% or more, preferably from 5 to 30%, more preferably from 10 to 30%.
  • the difference in opacity is less than 5%, it is difficult to recognize that the capsule content liquid released by breakage of the capsule is spread in the cavity of the filter because a decrease in the opacity of the laminated paper is not sufficient.
  • the opacity of a laminated paper formed by laminating a plug wrapping paper and a tipping paper may be measured before producing a cigarette.
  • a laminated paper formed of a plug wrapping paper and a tipping paper is cut out from the cavity of the cigarette, and the laminated paper may be measured.
