Abstract:
An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as the drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.
