摘要： A waterless urinal (10) has a siphon trap (13) removably arranged in an urinal bowl (11). The siphon trap (13) has an outer part (19) and an inner part (20) which at least in an overlapping area are cup-shaped and nested into each other, so that an outer compartment (23) for receiving a sealing liquid (S) is formed between a cup-shaped wall (21) of the outer part (19) and a cup-shaped wall (22) of the inner part (20), whereas an inner compartment (26) is formed between the cup-shaped wall (22) of the inner part (20) and a rising pipe (25) that leads to a connection (14) to the sewage system. The outer compartment (23) is in fluid communication with the inner compartment (26) through a first fluid communication area (29) and the inner compartment (26) is in fluid communication with the rising pipe (25) through a second fluid communication area (30). The outer part (19) forms a single piece with the inner part (20) and the rising pipe (25) so that spacing means (35) are provided to link a free marginal area of the outer part (19) to a circumferential marginal area (34) of a bottom wall (31) of the inner part (20), whereas the rising pipe (25) is linked to a bottom wall (28) of the outer part (19).
