Abstract
The invention concerns a fluid product dispenser comprising a gas reservoir (10), a fluid product reservoir (20), a dispensing head comprising at least one dispensing orifice (30). The gas reservoir and the fluid product reservoir are connected to the head so that their contents can communicate with the at least one dispensing orifice. The dispenser comprises a movable actuation wall (14; 24) to simultaneously generate a pressure state in the gas and fluid product reservoirs and thus force the fluid product and the gas through the the at least one dispensing orifice.
