ABSTRACT:
The invention provides a dispenser which can be suspended over the rim of a toilet bowl to dispense a dose of active ingredient into the bowl as the bowl is flushed. The dispenser draws active liquid from a reservoir in discrete doses, each does being released by a pumping action which is caused by the action of the flush water on the dispenser. The dispenser includes a flow restrictor which normally prevents egress of the active liquid from the reservoir but which releases a dose under the influence of the pumping action.
