Abstract
There is provided a rechargeable dispenser device for a liquid detergent product, comprising a removable cartridge (1) and a housing which is provided with a dosing chamber (6) coupled to a pump (7) which is manually movable by way of a rack and pinion system (12) and the stroke of which can be adjusted, whereby the size and shape of the cartridge (1) are such that a pouch containing the liquid detergent product can be fixed into it and that the cartridge with pouch can be tightly fixed in the housing so as to ensure an open but non-leaking connection between the detergent in the pouch and the dosing chamber, by way of an output nozzle of the pouch. This dispenser is particularly useful for accurately dosing concentrated liquid detergent products intended for hard surface cleaning, for instance in excess water.
