<p>The invention relates to a dispenser (1) for powdery compositions (M) contained in a separate pack, in particular compositions (M) contained in a blister pack (18), wherein the pack has a container part (14) with tear-off container cover (16), wherein furthermore an aspirated stream of air is sucked for the most part through the container part (14), after the container cover (16) has been removed from the container part (14), in such a way that two air streams (a, b) entering through slits (29) of a lid (19) empty the container part (15) from the direction of its two ends and, after coming together, pass into a swirl chamber (7) arranged upstream of a mouthpiece (3). In order to further optimize a dispenser in terms of flow technology, it is proposed that the air stream channel (27) designed as an arc-shaped path leads to the more distant end of the container part (14) and encompasses the container part (14) with an at least 180° curve area (52).</p> |
