Abstract:
A fluid dispenser comprising:an entraining gas reservoir (10) provided with actuating means (12â€²) 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 (31â€³; 31â€³â€²), said partition being 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; wherein the fluid is urged towards the dispensing orifice by thrust means (32â€³; 32â€³â€²) so that fluid is always present at the dispensing orifice; and wherein the partition (31â€³; 31â€³â€²) is mounted to move relative to and advantageously towards the dispensing orifice.
