The invention provides a adaptation to a rimstick dispenser of the type having a reservoir of active liquid and a flow controller to control the rate at which liquid is dispensed from the reservoir. In accordance with the invention a source of further active substance is provided so as to improve the efficacy of the dispenser, without otherwise affecting the assembly or operation of the dispenser. In one embodiment this source of further active is retained about the outlet neck of the reservoir so as to be sandwiched between the reservoir and the flow controller when the two components are assembled together.
