Here, the cylindrical corrugated bag 310 is made of unwoven fabric, synthetic resin, etc., and has an identifier such as a logo, attached to the blind end thereof, as illustrated in FIGS. 1 and 2.

[35] Further, the cylindrical corrugated bag 310 of FIG. 3 is designed to be expanded or contracted in one direction. The cylindrical corrugated bag 310 of FIGS. 4 and 5 is designed to be partitioned into a first expansion section 310a at the open end thereof and a second expansion section 310b at the blind end thereof, so that it is expanded or contracted in opposite directions. The cylindrical corrugated bag 310 of FIG. 6 is designed to be partitioned into a first expansion section 310a at the open end thereof and a second expansion section 310b at the blind end thereof, such that the second expansion section 310b has a diameter smaller than that of the first expansion section 310a, and thus is received into the first expansion section 310a when contracted. At this time, the cylindrical corrugated bag 310 is subjected to different types of heat treatment such that the first expansion section 310a thereof has a strong recovery force, and the second expansion section 310b thereof is easily expanded.

[36] Meanwhile, as illustrated in FIGS. 1 and 2, the collecting member 300 has a frame

320 formed in the shape of a ring. As described above, the ring-like frame 320 has fixed jaws 326 protruding from the opposite sides thereof in the diametrical direction so as to be fitted into the fixing recesses 212 of the fixing member 200, whereas each fixed jaw 326 is provided with a grip 328, which is exposed to the outside, at a free end thereof. In other words, the grips 328 are adapted to allow the collecting member 300, fitted into the fixing member 200, to be easily separated from the fixing member 200.
