INDICATEUR POUR DISPOSITIF DE DISTRIBUTION DE PRODUIT FLUIDE OU PULVERULENT

摘要

The indicator for a dispenser of a fluid or powdered product such as a metered dose inhaler has an actuator (1), a counter (5) with a ring of teeth (9), and a drive (6) with an elastic element that converts the axial movement of the actuator into a rotary movement of the counter. The elastic element is in the form of two flexible tongues (7, 8) with tips that engage with the counter teeth and rotate it in the same direction both when the actuator is depressed and when it returns to its initial position.
