Abstract
A dispenser for dispensing a fluid, said dispenser comprising: a reservoir (3) containing said fluid and provided with at least one actuating wall (10) on which pressure is exerted to reduce the volume of the reservoir, said reservoir being provided with resilient means (4) suitable for increasing the volume of the reservoir; a dispensing orifice (50) via which the fluid is dispensed as a mixture with a gas, so as to generate a two-phase spray; and a removable closure element (12) for closing the dispensing orifice (50), thereby isolating the reservoir from the outside; said dispenser being characterized in that the resilient means are stressed so that the reservoir defines a minimum volume so long as the closure element (12) closes off the dispensing orifice.
