Description

  In the present invention, elderly people, sick people, physically disabled people, etc. can leave the bed, but cannot go to the toilets that are permanently installed in hospitals, homes, etc., or the movement to the toilet is unstable The present invention relates to a portable toilet installed and used in a predetermined place such as a hospital room or a room.

  Conventional portable toilets prevent the emission of odors from the bucket by covering the bucket storing excrement with a lid. However, the conventional portable toilet cannot open and close the lid unless the toilet seat is opened, and the operation burden on the user is large. Therefore, in the portable toilet disclosed in Patent Document 1, a shutter that can open and close the opening of the bucket without opening the toilet seat is provided instead of the lid.

  However, in the portable toilet of Patent Document 1, since the shutter slides on the toilet body supporting the bucket, there is a possibility that odor in the bucket leaks from the gap between the bucket and the toilet body.

  Furthermore, in the portable toilet of Patent Document 1, the shutter is wound around the winding mechanism and stored in layers. Therefore, in the portable toilet of Patent Document 1, for example, when excrement is attached to the back surface of the shutter, the excrement adheres to the surface of the shutter that is in contact with the back surface to which the excrement is attached, and the excrement diffuses. There is a risk that.
