A medicament container configured to improve entrainment of the medicament in the air and to improve deposition of the medicament in the lungs includes an upper layer and a bottom layer with medicament disposed therebetween. The upper layer is punctured to provide first and second openings to allow airflow to enter and exit through the upper layer of the medicament container. In a preferred embodiment, the medicament container has a projection which forms an elbow-shaped medicament containment/flow channel between the upper layer and the lower layer. The medicament container is preferably used in a housing which selectively controls airflow through the medicament container and the housing to improve deep lung deposition of the medicament.
