Fluid product dispenser

Abstract

A fluid product dispenser includes a reservoir (3) containing said fluid product and provided with at least one actuating wall (10) on which pressure is exerted to reduce the reservoir volume, a dispensing orifice (50) communicating with the reservoir and through which the fluid product is dispensed out of the reservoir in a mixture with a gas to create a two-phase spray, a detachable sealing unit (12) to seal the dispensing orifice (50) and so isolate the reservoir from the outside, and a spring (4) to bring the actuating wall (10) into a non-operational position defining the maximum volume of the reservoir (3) when the sealing unit (12) is withdrawn from the dispensing orifice (50), said spring (4) being compressed when the sealing unit (12) seals the outlet orifice (50), the reservoir (3) containing approximately only fluid product so long as the detachable sealing unit (12) seals the dispensing orifice (50). so long as the detachable sealing unit (12) seals the dispensing orifice (50), the reservoir (3) is divided into several compartments (31, 32; 31′, 32′) by at least one partition (13; 13′), at least one (31; 31′) of the compartments containing the fluid product and at least one other compartment (32; 32′) containing the spring (4), but no fluid product, with the result that the fluid product is not in contact with the spring (4) before withdrawal of the sealing unit (12).
