An atomiser (1) is proposed for the delivery and in particular the atomisation of a formulation (2), particularly a powder. A simple construction and simple intuitive operation are made possible in particular by the fact that the atomiser has a mouthpiece (8) with an associated cover (10), so that opening and/or closing the cover (10) causes a delivery medium, in particular air, to be taken in and/or put under pressure by a delivery device, a spring store is put under tension and/or a preferably annular reservoir containing a plurality of doses of the formulation is further rotated.
