Abstract: A dispenser for dispensing an alcohol-glycerine disinfecting gel or liquid for use by doctors and nurses. The dispenser consists of a main housing which mounts a pumping mechanism for pumping out an alcohol-glycerine disinfecting gel from a replaceable, disposable supply-cartridge releasably mounted in the main housing.
