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.
