    • An apparatus for measuring doses of dispensed products includes a first metering ring (20) mounted to rotate 5 around a rotation axis (1), and drive means (10) that drives the first metering ring to rotate around an axis (1). The drive means (10) is actuated each time the dispenser is actuated. The apparatus also has interlocking means (15, 22) that engage the drive means (10) with the first metering ring (20) after the dispenser has been actuated a predetermined number of times. The first metering ring (20) is driven to rotate once it is engaged with the drive means (10). The apparatus only counts the doses of dispensed product after the dispenser has been actuated a predetermined number of times.
    • 用于测量分配产品的剂量的装置包括安装成围绕旋转轴线(1)旋转5的第一计量环(20)和驱动第一计量环绕轴线(1)旋转的驱动装置(10)。 驱动装置(10)每当分配器被致动时被致动。 该装置还具有互锁装置(15,22),其在分配器已被致动预定次数之后与第一计量环(20)接合驱动装置(10)。 一旦与驱动装置(10)接合,第一计量环(20)被驱动旋转。 该装置仅在分配器已被致动预定次数之后计数分配产品的剂量。
