Definitions

  • the present invention relates to a capsule for a smoking article with a liquid encapsulated therein, which is suitable for being adopted in a smoking article such as a filter-tipped cigarette, a filter in which the capsule for a smoking article is installed, and a smoking article equipped with the filter.
  • a liquid such as water or an aqueous solution having a flavor-emitting additive dissolved in water
  • a smoking article such as a filter-tipped cigarette when the smoking article is smoked
  • the liquid is previously encapsulated into a capsule to be incorporated into a filter body, and a user breaks the capsule before smoking the smoking article, to allow the liquid to gush out from the capsule and permeate into the filter.
  • the user applies force externally to the capsule by holding, between his/her fingers, the capsule from outside the filter, to break the capsule.
  • Capsules made of polysaccharide such as gelatin are, however, soluble in water and are not suited for encapsulating hydrophilic liquids, and the use of such water-soluble capsules is generally restricted to encapsulation of hydrophobic flavorings.
  • capsules made of synthetic resin are insoluble in water, are suited for encapsulating hydrophilic liquids and have excellent shape stability.
  • various means stated below have been contrived to facilitate breaking of the capsules.
  • a plurality of long radial grooves are formed in one end wall of the capsule, and when the capsule is applied externally with a crushing force, the grooves split off and allow the liquid contained in the capsule to gush out (Patent Document 1).
  • a capsule may be provided with a seal so that when the capsule is applied with external force, the seal may be broken to allow the liquid contained in the capsule to gush out (Patent Document 2).
  • a capsule which is obtained by fitting two capsule halves together via an annular seal, and when the capsule is squeezed, the seal is broken and allows the liquid contained in the capsule to gush out (Patent Document 3).
  • An object of the present invention is to provide a capsule for a smoking article with crush easiness (breaking easiness) being improved, a filter using the capsule for a smoking article like this, and a smoking article such as a filter-tipped cigarette.
  • a capsule for a smoking article in a substantially tubular shape that is installed in a filter of the smoking article, wherein a tubular circumferential wall, and a pair of end walls that respectively close both ends of the circumferential wall are included, a liquid is encapsulated in an interior, at least one of the end walls is elastically deformable, and groove-shaped thin-walled regions that are formed of straight lines or curved lines are provided in the one end wall to intersect at two or more intersecting points.
  • the capsule for a smoking article As for the capsule for a smoking article according to the present invention, a user can easily break the capsule, and thereby the liquid which is allowed to gush out of the capsule can be caused to permeate into a filter or a tobacco efficiently.
  • the filter in which the capsule for a smoking article like this is installed and the smoking article such as a filter-tipped cigarette adopting the filter, the user can easily crush the capsule and enjoy the improved smoking flavor.
  • FIG. 1 illustrates a case where a filter in which a capsule for a smoking article to be the first embodiment according to the present invention is installed is adopted in a cigarette CG as the smoking article
  • FIG. 2A illustrates a capsule CA-1 to be is installed in a filter FL of the cigarette CG

  • the groove sections 22 draw a hexagram in which two equilateral triangles are upright in normal and inverted orientations, by six straight lines that connect vertexes of the central section 20 in the shape of an equilateral hexagon. Accordingly, in the central section 20, six intersecting points 23 (meeting points) at which the straight-line groove sections 22 meet in such a manner as to intersect one another are formed, as shown by star symbols in FIG. 2B .

  • the lid member 13 is reliably fixed to the capsule body 10 by using an adhesive, thermal fusion treatment or the like so that the content in the capsule CA-1 does not leak out.
  • the same material as the capsule body 10 may be used, but a film material such as a laminate film is used, and the opening may be closed with heat seal.
  • the seal film can be bonded to an opening edge of the capsule body 10 by means of a thermoplastic adhesive.
  • adhesive hot-melt adhesive containing, as its main agents, an adhesive polyolefin resin, a low-molecular-weight polyethylene and EVA (ethylene vinyl alcohol) may be used, for example.
  • the lid member 13 may be formed into a shape which is flattened including a conical shape protruded inward so as not to be a hindrance when the capsule body 10 is crushed and flattened.

  • the liquid to be used may be a solution prepared by dissolving sugar, tobacco extract, fragrance and the like in water, or a water-based solution such as brandy, by way of example.
  • the liquid may be mixed with a chemical solution for preventing deterioration, where necessary.
  • minute solids such as microcapsules (perfume capsules) having perfume encapsulated therein may be used as the liquid, and such perfume capsules may be suspended in water to be used as the liquid.
  • a water-resistant sheet material is used for at least one of the casing 201 and the tip paper 101 so that the liquid may be prevented from leaking to the outside.
