摘要：
A portable toilet stool or bowl, upper opening of which is effectively closed by an air-curtain formed by currents of air flowing all over said opening, so that the smell of feces evacuated into the stool does not freely rise into the air from the upper opening, and the smell is forcibly subjected within the stool, to deodorizing and/or decomposition, and discharged into the air or circulated within the stool for a predetermined period of time.
