Abstract
Two-dose dosage system for fluid product dispensing device, the device having a syringe-type reservoir containing fluid product, a piston secured to a piston rod being slidably mounted in the reservoir to dispense the fluid product. The two-dose dosage system including a fixing portion which is fixed on the piston rod, a dose-splitting mechanism to separate the actuation stroke of the piston rod into two half-strokes, each for dispensing a respective dose, and an energy accumulation mechanism to generate a resistance upon each actuation of said piston rod.
