Artificial Grass Built Up of Fibres That Consist of a Core and a Cladding, as Well as an Artificial Lawn Built Up Therefrom

Abstract

The invention relates to a drain for liquid comprising a detachable pipe part provided with a stench-trap, placed substantially horizontal in or in connection to a drainage pipe, wherein the pipe part comprises positioning means for placing the pipe part in or in connection to the drainage pipe with a substantially univocal orientation. In one embodiment the drain comprises a receptacle having a bottom wall and raised side walls, wherein the raised side walls comprise a first side wall provided with a drainage opening placed therein, wherein the drainage pipe is placed at an outside of the receptacle so as to connect to the drainage opening. The drain according to the invention is particularly suitable for placement in for instance a finishing floor of a wet area in a building, such as for instance a bathroom or a shower cubicle.
