  • the diameter and length of the protrusion 48 is about 0.4 to 0.5 mm, for example.
  • the protrusion 48 described above is useful for determining the break position when the V-shaped groove 36 or the thin region 46 is broken. Specifically, when an external force F is applied to the capsule body 24 and a specific linear portion in the specific V-shaped groove 36 or thin region 46 is pulled, the tensile stress is concentrated at the root of the protrusion 48. As a result, the protrusion 48 becomes a breaking point and determines the breaking position. In addition, since the protrusion 48 does not protrude from the end wall 26 to the outside of the capsule 22, it is difficult for an undesired impact to be applied to the protrusion 48, and due to such an impact, the end wall 26 extends from the root of the protrusion 48. It is also less likely to break undesirably.
  • FIG. 14 shows the capsules 22a to 22d when an external force F is applied to the capsules 22a to 22d of the first to fourth embodiments E1 to E4 and the capsules 22a to 22d are broken at the V-shaped groove 36 or the thin wall region 46. The result of having measured the average value of the breaking load of 22d is shown. FIG. 14 also shows the measurement results of the average value of the breaking load for the capsules of Comparative Example C and Reference Example R.
  • each capsule When measuring the breaking load, each capsule is filled with 94% of the liquid (distilled water), and a creep meter (manufactured by Yamaden Co., Ltd., RHEONER II (trade name)) is used to measure the breaking load. It was done. Before mentioning the measurement results of FIG. 14, the capsules of Comparative Example C and Reference Example R will be briefly described.
  • the capsule of Comparative Example C corresponds to the capsule of Patent Document 1 described above, and the capsule of Reference Example R corresponds to a seamless capsule incorporated in a commercially available filter cigarette.
  • the breaking load of the capsules 22a to 22d of the first to fourth embodiments E1 to E4 is significantly smaller than the breaking load of the capsule of the comparative example C, and the breaking of the capsule of the reference example R Approximate to load. Therefore, it can be seen that the capsules 22a to 22d of the first to fourth embodiments E1 to E4 break more easily than the capsule of the comparative example C.
  • the breaking load of the capsule 22c is smaller than the breaking load of the capsule 22a.
  • the breaking load of the capsule 22d is smaller than the breaking load of the capsule 22b.
  • the present invention is not restricted by the first to fourth embodiments E1 to E4 described above.
  • the capsule main body 24 and the sealing member 40 as the closing wall in the above-described embodiments are both made of low density polyethylene.
  • the capsule main body and the closed wall of the present invention can be formed of a synthetic resin other than low density polyethylene, and further can be formed of a material other than the synthetic resin.
  • the capsule body 24 of the first embodiment E1 has a peripheral wall 30 that is tapered toward the end wall 26.
  • the capsule body can also have a peripheral wall having a straight cylindrical shape or a reversely tapered shape.
  • the end wall of the capsule body of the present invention may be a concave wall having a form different from the end wall 26 of the first to fourth embodiments described above.
  • the end wall 26 may have a flat central portion 34.
  • the entire area of the hemispherical portion 44 may be formed as a thin wall region.
  • the thin wall region has a shape other than the V-shape. It may be formed as a groove. Furthermore, the arrangement of the grooves is not limited to a radial shape.
  • the thickness in the thin region is preferably 0.1 mm or more and less than 0.2 mm on the premise that the thickness is smaller than the thickness of the end wall or the peripheral wall of the capsule body. More preferably, the thickness of the thin region is not less than 0.12 mm and less than 0.17 mm.
  • the capsule body 24 of the first and third embodiments E1 and E3 has a plurality of ribs 42 on the outer peripheral surface thereof.
  • these ribs 42 may be provided on the inner peripheral surface of the capsule body 24, and such ribs 42 are provided on the outer peripheral surface or inner periphery of the capsule main body 24 in the second and fourth embodiments E2 and E4. The same applies to the surface.
  • the capsule of the present invention has a basic structure including a capsule body, a concave end wall of the capsule body, a thin wall region formed on the end wall, and a closed wall that closes the open end of the capsule body.
  • the other components (including shape and arrangement) of the capsules of the embodiments can be applied in any combination with the other embodiments.
  • the capsule of the present invention can be incorporated not only into a filter cigarette but also into various smoking articles.
