A doser-dispenser has a single doser unit which is associated with at least two dispenser units. The outlet of the dosing chamber of the doser unit is connected in parallel to each of the dispensing chambers of at least two dispenser units. The active volume of the dosing chamber holds at least two whole doses of product to be dispensed through the two distinct dispenser units. A synchronization device which coordinates the movements of the doser-piston and of the intake flap, with a result that, during delivery of a first dose of product out an dosing chamber, only the ejection valve of the first dispenser unit is open, that, during delivery of the second dose of product, only the ejection valve of the second dispenser unit is open, and so on.
