1. A dose delivery device, comprising:
a lower portion and an upper portion defining a reservoir for containing a dose and including a single reservoir opening, at least a portion of the reservoir including a curved surface, and the reservoir being openable, wherein the upper portion and the lower portion define an opening mechanism movable from a closed position to an open position,
wherein, with the reservoir opened, the lower and upper portions define an air flow path generally along and across at least a portion of the single reservoir opening of the reservoir from an inlet opening to an outlet opening, such that at least a portion of air in the air flow path enters the reservoir through the single reservoir opening to entrain the dose in the reservoir, and air including entrained dose exits the reservoir through the single reservoir opening and then exits the outlet opening in a direction that is not back toward the inlet opening.
