Abstract: A dispenser device for fluid or powder, including an air expeller (20) and a reservoir (30). The reservoir (30) has an air inlet (31) connected to the air expeller (20) and a composition outlet (32) connected to a dispenser opening (10), and is removably mounted on the air expeller. After actuation, the empty reservoir can be removed from the air expeller and replaced with a new reservoir. The air inlet (31) is closed by a first closure element (40) and the composition outlet (32) is closed by a second closure element (50). A mechanical opening system (61, 62) co-operates with the first and second closure elements to expel each closure element from the closed position. The mechanical opening system has a first rod (61) secured to the air expeller (20), and a second rod (62) secured to the dispenser head (1), co-operating with a closure element during actuation.

Abstract: A method of using a fluid dispenser unit having a reservoir and a piston that slides in the reservoir. The unit includes an extractor head secured to the reservoir to suck fluid to be dispensed into the reservoir, and a spray head assembled on the extractor head to spray the fluid out from the reservoir. The method includes the steps of sucking a fluid to be dispensed into the reservoir through the extractor head; assembling the spray head on the extractor head; and spraying the fluid through the spray head. The step of sucking up a fluid to be dispensed includes a first step of extracting a fluid, such as a solvent, from an extraction reservoir, and a second step of mixing the fluid with a first substance, such as a powder or a lyophilisate, so as to form the fluid to be dispensed.
