BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collapsible trash can assembled from a plate-like material such as cardboard or corrugated paper, and more particularly, to the inside of a box main body assembled in a box shape. An inner bag formed of a synthetic resin film or the like is stored in the inner bag, and the opening of the inner bag is fixed in accordance with the assembly of the box main portion, and garbage to be thrown in from the opening of the box main portion is stored. The present invention relates to a trash box that can be reused by being taken out of the box main part when it becomes full, and by attaching a new inner bag. Conventionally, so-called simple trash cans that are assembled into a box shape using corrugated paper have been widely known. Various types of trash cans that have been easily cleaned by extracting bags are also known. And furthermore, in order to facilitate the mounting of the above inner bag, the inner bag continuous in a cylindrical shape is previously wound in a roll shape inside the garbage bin main body, pulled out every time the garbage becomes full, and separated from the next bag portion, There is also known a trash can in which a bag portion filled with trash is taken out, and the next bag portion is mounted in the trash box. The type of garbage bin that puts the inner bag inside the trash can is easy to clean up when throwing away the garbage, and by making this inner bag a waterproof sheet such as a plastic sheet, it can be used for garbage containing moisture. There are excellent advantages such as hygienic handling. However, on the other hand, when the inner bag is used, the mounting is troublesome and the appearance is deteriorated. It is necessary to attach the inner bag with the opening open, but specifically, in addition to being easy to remove, if it is not firmly attached, it will come off when throwing in garbage and the inner bag itself will become garbage Sometimes. Therefore, in general, the opening edge of the inner bag is folded back to the outside of the opening edge of the garbage bin and fixed by a frame, or wrapped with a string and fixed by a method such as this. There is a problem that the appearance of the garbage can be impaired because the edge of the garbage can go out of the trash can, and it is not suitable for some places of use.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of a trash can in which an inner bag is housed, so that an opening edge of the inner bag can be easily attached to an opening mainly formed of the trash box, thereby facilitating mounting work. At the same time, the inner bag is fixed firmly so that it does not come off when throwing in garbage. This was done to provide a trash can. In addition, the present invention allows the trash box main body to be folded so that it can be compacted when not in use, and can simultaneously perform the work of fastening the inner bag at the time of assembling in use so that another fastening means is provided. It is an object of the present invention to provide a trash can manufactured using cardboard, cardboard, or the like, in which the inner bag can be freely attached and detached and fixed inside the trash can main body without necessity.
