An atomizer for the delivery, and in particular, for the atomization of a formulation, particularly, a powder has a simple construction that makes a simple intuitive operation possible. In particular, such is achieved by the fact that the atomizer has a mouthpiece with an associated cover, so that opening and/or closing of the cover 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.
