The invention discloses a dosimeter for products dispensed by a fluid or powdery product dispenser, the said dispenser comprising: a first metering ring (20) rotatably mounted about a rotation axis (1), and drive means (10) capable of co-operating with the said first metering ring (20) for driving it in rotation about the said axis (1), the said drive means (10) being actuated each time the dispenser is actuated. The invention is characterised in that the said device comprises interlocking means (15, 22) for engaging the said drive means (10) with the said first metering ring (20) after a predetermined number of times the dispenser has been actuated, the said first metering ring (20), being driven in rotation only as from the moment it is engaged with the said drive means (10), such that the dosimeter counts the doses of the product dispensed only after the predetermined number of times the dispenser has been actuated. |
