    Abstract: An autoinjector comprising: a body (1) receiving a reservoir (S), said reservoir (S) containing fluid and including a piston (P), such as a pre-filled syringe; a piston rod (5) that is adapted to co-operate with the piston (P) of said reservoir (S), said piston rod (5) being movable by an injection spring (8) between a primed position and an injection position in which said piston rod (5) has moved the piston (P) of the reservoir (S) so as to inject the fluid into an injection site; and a visual, audible, and/or tactile indicator device for indicating to the user that said autoinjector may be removed from said injection site; said autoinjector including a retarding system for delaying the actuation of said visual, audible and/or tactile indicator device relative to the end of injection, said retarding system including a dashpot (16) containing a fluid, a piston (19) being arranged in said dashpot (16), one of said dashpot (16) and of said piston (19) being movable in translation in said body (1) during actuation of said retarding system, and the other of said dashpot (16) and of said piston (19) being stationary relative to said body (1) during actuation of said retarding system, the movement in translation of one relative to the other moving said fluid out from said dashpot (16) through at least one flow passage (161; 195), such that said movement in translation is braked, said retarding system comprising said dashpot (16) containing said fluid, said piston (19), a locking key (20), said injection spring (8), a pusher element (17), a support member (6) interposed between said pusher element (17) and said injection spring (8), and said piston rod (5).

    Abstract: A fluid product dispensing device having a reservoir with a dose of fluid product, a piston-stopper mounted to slide in the reservoir, a dispensing head with a dispensing orifice axially movable to move the piston-stopper to dispense the fluid product. The piston-stopper has a hollow sleeve with a central receiving zone substantially at the axial and radial center of the piston plug. A shut-off element is positioned in the central receiving zone in a shutting-off position and, during actuation, expelled from the shutting-off position towards an open position. The central receiving zone is extended axially on one side by a lower receiving zone having two wall parts separated by at two axially extending radial grooves, the wall parts holding the shut-off element in its open position, with the fluid product able, during actuation, to flow from the reservoir around the shut-off element in the open position towards the dispensing orifice.

    Abstract: An autoinjector having a body (1) receiving a reservoir (S) containing fluid and including a piston (P), such as a pre-filled syringe; a piston rod (5) that co-operates with the piston (P), the piston rod (5) being movable by an injection spring (8) between a primed position and an injection position in which the piston rod (5) has moved the piston (P) of the reservoir (S) so as to inject the fluid into an injection site; and an indicator device for indicating to the user that the autoinjector may be removed from said injection site. The autoinjector also includes a retarding system to delay the end of actuating the indicator device relative to the end of injection, the indicator device generating a noise while being actuated, the noise being generated until the end of actuating the indicator device.
