ABSTRACT:
A floor drain or some other cup-shaped water seal, comprising a cupped body (1), a superstructure including a trash screen (2), a water seal forming wall (3), and an outlet (4) for a sewer pipe (5). A problem is to improve the superstructure of a floor drain so as to prevent bacteria from spreading out along moist surface films or membranes. In order to resolve the problem, the superstructure is provided with a funnel-shaped ring (6), which is fitted below trash screen (2) and whose central hole (7) is smaller than said outlet (4) and whose outer rim is tightly (8) sealed to body (1).
