Abstract
A dosing device with which several, preferably two, liquids can be measured and dispensed in precise quantities. In this dosing device, two bottle-top dispensers with integrated suction valves, discharge valves and a bottle-top mechanism are attached in a housing. A liquid-reservoir bottle can be affixed to the bottle-top mechanism of each bottle-top dispenser. In particular, affixing of the respectively associated reservoir bottles is ensured without confusion. Activation of the pistons of the bottle-top dispensers takes place with working strokes which differ depending on the spacing. In addition, the housing comprises a blow-out device by means of which, after each dispensing procedure, the discharge device for the liquids can be blown out and cleared of any liquid residues.
