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.

Abstract: A pump for a vial intended to contain a cosmetic product includes a variable-volume dosing chamber defined at least partially by a deformable element. The pump operates by varying the volume of the chamber by elastic deformation of a membrane of the deformable element from an initial state wherein the chamber has a maximum volume to a deformed state wherein the volume of the chamber is minimal. The chamber is provided with a product inlet orifice and a product outlet orifice, and the pump includes deform the membrane by exerting pressure on the membrane. Finally, the pump purges the air from the chamber when the membrane is in its deformed state, by enabling the dosing chamber to communicate with the outside of the pump.

Abstract: A pump for a vial intended to contain a cosmetic product. The pump includes a dosing chamber with a variable volume defined at least partially by a deformable element between an initial state and a deformed state. The pump further includes a guiding rod passing through the deformable element, the latter sliding along the rod when it undergoes a deformation. The deformable element includes an outlet lip delimiting an outlet orifice, surrounding a section of the rod, and bearing in a sealed manner against the rod or deviating from the rod according to the pressure in the chamber. A clamping edge extending from the rod maintains the outlet lip bearing in a sealed manner against the rod when the membrane is in the initial state thereof whatever the pressure in the chamber and whatever the pressure around the pump.
