A dispenser device including a dispenser head (1), an outlet (10); an air expeller (20), and a reservoir (30). The reservoir includes an air inlet (31) connected to the air expeller and a composition outlet (32) connected to the dispenser outlet. The air inlet includes a composition retainer member (40), and the composition outlet (32) is closed by a closure element (50) force fitted in the composition outlet. A mechanical opening system (61, 62) co-operates with the closure element (50) to expel it. The reservoir removably mounted on the air expeller, so that after actuation, the empty reservoir can be removed and replaced. The air expeller is returned to its rest position while an empty reservoir is replaced. A breakable part (70) is assembled on the reservoir and/or the dispenser head and includes an indicator element (71) connected by a breakable bridge (72).
