Abstract

A liquid dispensing unit for a toilet bowl comprises a first container containing a first, liquid formulation, a second container containing a second formulation, which may be a solid tablet. The liquid from container flows onto a delivery surface from where it is washed into the toilet bowl by the flush water. Some flush water also washes over the second formulation to take components into solution and deliver them into the toilet bowl through aperture. The constituents of the two formulations are thus kept separate until they enter the toilet bowl. The second formulation may also be a liquid.
