An atomiser (1), a reservoir (3) and a method are proposed for the delivery and in particular the atomisation of a formulation (2), particularly a powder. A pump and a spring (14) are arranged inside the annular reservoir, wherein the pump and the spring (14) are moveable radially and in a sliding manner. The pump is actuated by the spring (14) to put air under pressure for discharging powder from the reservoir (3). The reservoir (3) comprises receptacles (4) or cavities each comprising an insert with a respective dose of the formulation (2). The receptacles (4) are constructed as separate parts and/or arranged on a common or annular carrier and/or are sealed separately and/or on its outer circumferential periphery. The spring (14) is tensioned and the air is sucked into the pump. Then, the next receptacle (4) and a connecting element (24) are aligned relative to each other. Finally, the aligned receptacle (4) is pierced by the connecting element for supplying the air. |
