Abstract

Dry powder inhalers include an elongate body and a disk holding a plurality of doses of a dry powder inhalable product. The inhaler also includes a cover member that is pivotably attached to the elongate body so that it remains attached to the body during normal operational periods of use and moves to a first closed position to overlie the inhalation port at the bottom end portion of the body during periods of non-use and moves to a second open position away from the inhalation port during periods of use to allow a user to access the inhalation port.
