Abstract

An atomizer for the delivery, and in particular, the atomization of a formulation, particularly, a powder. A simple construction and simple intuitive operation are made possible, in particular, 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.
