. Further, an installation called “trash chute system” has also been employed which is provided in a building for conveying refuse. The trash chute system is of a vertically extending hole structure in which a trash chute de?ned by surrounding side walls extends verti cally through a building, and has throwing openings in one of the side walls at respective floors through which openings residents can throw refuse. When using the trash chute, residents put refuse in the home in a container such as a plastic bag, plastic or metal bucket or the like, bring the bag or the like con tainer containing the refuse to the nearest opening and throw away the refuse into the trash chute, with the refuse contained in the bag or with the refuse being taken out of the bucket before throwing. The refuse falls down to the bottom of the chute at the lowest floor and is accumulated there. The accumulated refuse is taken out from the bottom portion of the chute at prede termined interval, e.g., once a day or twice a weak. The conventional refuse transporting methods as described above have various problems. That is, in the former case, carrying the refuse to the accumulation site on foot is a time-consuming job for residents and bad smell is discharged from the refuse and hangs in the air on the way of carrying the refuse from each home to the accumulation site. Also, in the former case, comfortable or hygienic environment in the home is disrupted by the bad smell or the like discharged by the refuse which the residents are compelled to keep in the room in order to avoid dumping it in a public space such as the accumu lation site on the day or days other than the speci?ed gathering day(s). In the latter case, the refuse adheres to the inner walls of the trash chute and the adhering re fuse gives off a bad smell in the air.
