Claims19
A delivery device comprising:
- a primary air pathway having an upstream portion and a downstream portion;
- a dose chamber having an opening that, when opened, places the dose chamber and the primary pathway in fluid communication at a position between the upstream portion and the downstream portion;
- and
- a cover that, in a first position over the opening, closes fluid communication between the dose chamber and the primary air pathway and that moves to a second position to selectively open fluid communication between the dose chamber and the primary air pathway through the opening, the cover being positioned to divert air to the dose chamber from the upstream portion of the air pathway when in the second position.
