Abstract
A liquid delivery device is particularly suited for dosing a toilet bowl with a viscous cleaning agent. Liquid from a reservoir 10 flows through a neck 52 into a cup 18 until the liquid level reaches the mouth 54 of the neck 52. The space 14 in cup 18 is open to atmosphere. Liquid is drawn from the cup 18 by a capillary 66 formed between the wall of cup 18 and an insert 60 and delivered on to the surface 72 of a textile layer 6. Flush water runs over textile layer 6 to carry the liquid into a toilet bowl.
