  • the peripheral wall 10 of the capsule CA-1 has an easy-to-break structure such that the capsule CA-1 easily breaks when applied with such external forces.
  • the peripheral wall 10 has a thin-walled region, as described below.
  • the thin-walled region is a region of which the wall thickness is smaller than the other region so that the thin-walled region may be easier to break than the other region applied with stress.

  • the peripheral wall 10 of the capsule CA-1 has the main thin-walled region 10a (in the figure, four thin-walled regions) directed parallel to the direction of application of the external forces F. Since the main thin-walled regions 10a are provided, the capsule CA-1 is deformed progressively as the external forces are applied, and when the stress acting in bent portions 13 where stress is concentrated due to the bending exceeds a certain value, the capsule CA-1 breaks as illustrated. The pressure in the capsule CA-1 rises with the application of the external forces F, and therefore, forces directed perpendicularly to the direction of application of the external forces F are generated in the capsule CA-1. Consequently, the main thin-walled regions 10a directed parallel to the direction of application of the external forces F are broken easily.
  • FIG. 3 illustrates an improvement example of the capsule, wherein the capsule is provided not only with the ring-shaped main thin-walled regions 10a but also with straight sub thin-walled regions 10b perpendicular to the main thin-walled regions 10a.

  • FIG. 5B illustrates the capsule CA-2 taken out of the filter FL-2.
  • the exemplary capsule CA-2 illustrated in FIGS. 5A and 5B has at least one straight main thin-walled region 10c extending along the axis CL of the tubular peripheral wall 10 (in a direction perpendicular to the peripheral direction of the peripheral wall). As shown in FIG. 5A , the tubular capsule CA-2 is disposed within the space 204 such that the axis of the capsule CA-2 is directed perpendicularly to the axis of the filter.
  • the straight thin-walled regions 10c extend in such a direction that when the filter FL-2 is picked and applied with radial external forces F, the thin-walled regions 10c are parallel with the direction in which the external forces F are applied.

  • the peripheral wall 10 of the capsule CA-2 has the main thin-walled regions 10c that are directed parallel to the direction of application of the external forces F. Since the main thin-walled regions 10c are provided, the capsule CA-2 is deformed progressively as the external forces are applied, and when the stress acting in the most bent portions 13 where stress is concentrated due to the bending exceeds a certain value, the capsule CA-2 breaks at the bent portions 13, as illustrated. The pressure in the capsule CA-2 rises with the application of the external forces F, and therefore, forces directed perpendicularly to the direction of application of the external forces F are generated in the capsule CA-2. Consequently, the main thin-walled regions 10c parallel to the direction of application of the external forces F are broken easily.
  • the location of the capsule CA-2 in the accommodation space 204 be visually identifiable.
  • the casing 201 of the filter body surrounding the accommodation space 204 is made of a transparent sheet material so that the accommodation space 204 can be viewed from outside.

  • the main thin-walled regions 10c extend straight along the axis CL of the capsule, and the sub thin-walled regions 10d are each in the form of a ring. With the sub (auxiliary) thin-walled regions 10d formed in this manner, the capsule CA-2 can be broken more easily.
  • the main thin-walled regions 10c and the ring-shaped sub thin-walled regions 10d need not be continuous regions. That is to say, the thin-walled regions may be non-continuous regions having discontinuities in part thereof, as stated above.
  • the aforementioned capsule CA-2 of the second embodiment was actually produced and evaluated, as described below.
  • the capsule CA-2 was produced using distilled water as the liquid to be encapsulated in the capsule, and breaking strength of the produced capsule CA-2 was measured. Specifically, using low-density polystyrene, which is a plastic material used for food packaging, the capsule CA-2 was formed by injection molding. Then, 90% (v/v) distilled water was poured into the space within the capsule CA-2, and the open end of the capsule CA-2 was completely heat sealed with a polyamide/low-density polyethylene laminated film (KIMURA-TEC, NY/LDPE, 60 ⁇ m), to obtain a capsule containing distilled water.

  • the shape of the capsule CA-2 is, however, not limited to cylinder, and as shown in FIG. 9 by ways of example, the capsule CA-3 may be in the form of a prism (in the figure, quadrangular prism (rectangular parallelepiped)). Where the capsule has a prismatic shape, its posture inside the accommodation space 204 can be stabilized. In this case, the thin-walled regions 10c are formed in the four side walls constituting the peripheral wall of the capsule.
  • the capsule CA-3 may be disposed within the accommodation space 204 such that the side walls of the capsule CA-3 are directed parallel with the axis of the filter, in which case the four side walls face frontward, rearward and to the right and left, respectively, with respect to the filter.
