Abstract: A fluid dispenser including: an entraining gas reservoir (10) provided with an actuator (12′) suitable for pressurizing the gas contained in the reservoir; a fluid reservoir (3); and a dispensing orifice (21) serving to pass a mixture made up of entraining gas and of fluid; the fluid reservoir (3) being separated from the gas reservoir (10) by a partition (31″; 31″′). The partition is permeable to the gas and impermeable to the fluid, so that the pressurized gas penetrates into the fluid reservoir (3) through the partition, and entrains the fluid with it towards the dispensing orifice. The fluid is urged towards the dispensing orifice by thrust mechanism (32″, 32″′) so that fluid is always present at the dispensing orifice.

Abstract: Fluid product dispenser having a fluid product reservoir (13) containing a fluid product, the reservoir (13) and, a distribution orifice (32; 22) through which the fluid product is forced in the form of a spray when the actuation wall (36) is pressed. The reservoir includes a deformable actuation wall (36) that is pressed to reduce the internal volume of the reservoir, a bottom plate (1), an intermediate plate (2) defining an opening (24), and a cover plate (3) including the actuation wall (36), and wherein the opening (24) is formed in the intermediate plate (2) defining the useful volume of the reservoir (13) with the bottom plate (1) and the cover plate (3).

Abstract: A fluid product dispenser having a distribution orifice and a variable volume reservoir that varies by displacement of a mobile wall in order to reduce the volume of the reservoir. The dispenser is provided with an actuation device to move the mobile wall of the reservoir. Advantageously, the actuation device is rotary and has a thread that is engaged with the reservoir.
