Definitions

  • the present invention relates to a cigarette in which opacity of an outward appearance of a filter portion is improved.
  • a cigarette with a filter (hereinafter, referred to simply as a cigarette) has a structure in which a filter portion and a tobacco portion containing cut tobaccos are placed opposite to each other at their ends and integrally connected with each other by wrapping the whole of the filter portion and a base end part of the tobacco portion with a tipping paper.
  • black absorbents such as activated carbons are dispersed in at least one of a plurality of filter sections constituting the filter portion of the above described cigarette from a viewpoint of a health risk or desire of a milder smoking taste.
  • such a cigarette has a problem that the black absorbents in the filter portion can be seen through outwardly.
  • the tipping papers described in these documents create disadvantages such as a dramatic decrease in rigidity of the tipping paper (soft paper), a decrease of bonding force between the fiber and fiber in the tipping paper (paper easily peeled off) and the like.
  • wrinkles or a breaking of the tipping paper arises in a printing process or in a rolling-up process, causing a large amount of paper dust.
  • the above described tipping papers are more likely to be wet and thus, when a consumer puts the filter portion of the cigarette in his (her) mouth, the above described tipping paper is more likely to be broken due to saliva.
  • an effect of increasing opacity by increasing the filler is curbed so that a relatively large amount of filler is needed to further increase the opacity of the tipping paper.
  • tipping paper thicker is effective in increasing opacity without increasing the filler.
  • a difference between an inner circumferential length and an outer circumferential length in the thick tipping paper becomes large when the thick tipping paper is rolled, so that a roundness of the filter portion is likely to be distorted and many wrinkles is likely to be generated on the rolled thick tipping paper.
  • An object of the present invention is to provide a cigarette having high quality in which outward opacity of a filter portion is improved to 92% or more, so that black absorbents of the filter portion are hard to be seen through and a white clean impression of the filter portion is obtained.
  • a cigarette comprising:
  • the cigarette according to the embodiment comprises a filter portion having a plurality of filter sections arranged to be integrated with each other, a material paper winding around each filter section and a shape-forming paper winding around the integrated filter sections around each of which the material paper is wound, and a tobacco portion in which tobacco material is rolled by a cigarette paper.
  • the filter portion and the tobacco portion are placed opposite to each other at their ends and integrally connected with each other by wrapping the whole of the filter portion and a base end part of the tobacco portion with a tipping paper.
  • At least one of the filter sections contains black absorbents dispersed therein.
  • the material paper winding around the filter section containing the black absorbents has opacity of 78% or more. Ventilation holes are opened in advance in a part of the tipping paper positioned on the filter section containing no black absorbents.
  • the inventors studied a relationship between a change of outward opacity of a filter portion (a region in which a tipping paper is wound around and which includes a filter section in which activated carbons are dispersed) and a degree (visual sensory value) which indicates how activated carbons in the filter section can be seen through the tipping paper on the filter portion, and obtained a result shown in FIG. 1 .
  • a change of outward opacity of a filter portion a region in which a tipping paper is wound around and which includes a filter section in which activated carbons are dispersed
  • a degree visual sensory value
  • a is a characteristic line when a filter section to which 25 mg of activated carbons is added per 10 mm is used
  • "b” is a characteristic line when a filter section to which 50 mg of activated carbons is added per 10 mm is used
  • "c” is a characteristic line when a filter section to which 75 mg of activated carbons is added per 10 mm is used.
  • Arrows in FIG. 1 indicate opacity of the tipping paper.
  • outward opacity of the filter portion of at least 92%, preferably 94%, is needed to realize a level of "dimly visible", in other words "hardly visible", in the filter portion.
  • outward opacity of the filter portion when the shadows are not able to be seen through at all is 98%.
  • the inventors found that there is a limit to improve opacity of the filter portion by increasing opacity of the tipping paper. And, the inventors particularly focus on a material paper wound around each of filter sections, among a filter wrapping paper (generic name for both of a material paper and a shape-forming paper) of the filter portion, and produce a cigarette with a filter portion having outward opacity of 92% or more to produce a white clean impression of the filter portion while a conventional tipping paper can be used and a filter ventilation can be maintained.
  • a filter wrapping paper generic name for both of a material paper and a shape-forming paper
  • the main function required for the filter wrapping paper is a shape-forming function for a filter and a predetermined permeability. And, since the filter wrapping paper is hidden by the tipping paper and normally invisible, the filter wrapping paper has not been required to have high opacity. Requiring the filter wrapping paper to have such an arbitrarily high level of opacity can be firstly focused on only by the above described view point of the present inventors and it is difficult even for those skilled in the art to think of such an idea.
  • a permeability required for the wrapping paper is to maintain filter ventilation.
  • a level of opacity of each of a filter wrapping paper and a tipping paper and permeability thereof are correlated, and the permeability tends to decrease with an increase of the level of opacity. That is, the filter wrapping paper with a high level of opacity has air permeability lower than that of a conventional filter wrapping paper, so that it is difficult to maintain sufficient filter ventilation.
  • a cigarette including a filter portion having outward opacity of at least 92% while sufficient ventilation being maintained can be obtained by winding only a material paper with opacity higher (78% or more) than that of a conventional material paper around a filter section containing black absorbents, using a conventional paper with high permeability as the material paper winding around a filter section containing no black absorbents and as a shape-forming paper winding around all of the filter sections, and further setting opening positions of ventilation holes of a tipping paper wrapping around the filter portion and the tobacco portion within a range of the filter section containing no black absorbents.
  • a general-purpose tipping paper having appropriate rigidity and thickness and also having a good roll-up characteristic can be used, there is no need to add a large amount of fillers to the tipping paper or to make the tipping paper thicker and, therefore an excellent cigarette in which streaks of wrinkles are hardly visible can be obtained.
  • the plurality of filter sections used in the embodiment there is, for example two-sections type (dual type) or three-sections type (triple type).
  • the filter section can be formed from, for example, a tow of cellulose acetate fibers.
  • the tow of cellulose acetate fibers can be bound by treating it with triacetin.
  • activated carbons can be used as the black absorbents dispersed in the filter section. It is preferable that 25 mg or more, more preferably 50 mg or more, of the black absorbents are dispersed for a length (10 mm) of the filter section.
  • the material paper wound around the filter section containing the black absorbents has opacity of 78% or more.
  • a material paper preferably has a composition of, for example, pulp and fillers such as calcium carbonate, titanium oxide, etc.
  • the more preferable opacity of the material paper is 85% or more. If opacity of the material paper is increased excessively, it becomes difficult to make the material paper. Therefore, it is preferable to set the upper limit of opacity to 95%.
  • the material paper wound around the filter section containing the black absorbents preferably has a thickness of 30 ⁇ m to 100 ⁇ m.
  • Opacity can be measured by a measuring method of an example described later.
  • the material paper wound around the filter section containing no black absorbents is a conventional product.
  • the material paper whose opacity is 20% to 40% can be used.
  • the conventional material paper preferably has a thickness of 30 ⁇ m to 100 ⁇ m.
  • the shape-forming paper wound around the filter sections around each of which the material paper is wound and which are arranged to be integrated with each other is a conventional product.
  • the shape-forming paper having opacity of 20% to 40% can be used.
  • the shape-forming paper preferably has a thickness of 30 ⁇ m to 100 ⁇ m.
  • the tipping paper is a conventional product.
  • the tipping paper having opacity of 78% to 85% can be used.
  • the tipping paper preferably has a thickness of 30 ⁇ m to 100 ⁇ m.

  • the filter portion 2 includes a first filter section 21a arranged in a side of the tobacco portion 1 and a second filter section 21b adjacent to the first filter section 21a.
  • the first filter section 21a is shaped by winding a first material paper 23a around a tow of acetate fibers or folded nonwoven fabrics of pulp, in which black absorbents, for example activated carbons 22, are dispersed, to form a cylindrical shape.
  • the first material paper 23a has opacity of 78% or more and the thickness of, for example, 30 ⁇ m to 100 ⁇ m.
  • the second filter section 21b is shaped by winding a second material paper 23b around a tow of acetate fibers or folded nonwoven fabrics of pulp to form a cylindrical shape. That is, the second filter section 21b contains no black absorbents.

  • the shape-forming paper 24 is a conventional shape-forming paper having, for example, opacity of 20% to 40% and a thickness of 30 ⁇ m to 100 ⁇ m.
