Abstract
A pump for dispensing a fluid product, able to be mounted on a container of the flexible tube or rigid flask type, includes a variable-volume metering chamber at least partly defined by a membrane deformable between an initial state in which the volume of the metering chamber is maximum and a deformed state in which the volume of the metering chamber is minimum. The pump also includes a valve for admitting the fluid product to the metering chamber. The pump further includes a valve for discharging the fluid product from the metering chamber. Finally, the pump includes means for opening and closing the admission and discharge valves. Notably, the pump consists of a single molded piece.
