Abstract
Inhalers with an inhaler housing having a dose container disk having inner and outer perimeters mounted in the housing. The dose container disk has a plurality of circumferentially spaced apart dose containers with dry powder therein. The inhalers also include a piercer carriage with a piercer mounted in the inhaler. The piercer carriage is in communication with a resilient member that radially biases the piercer carriage to radially travel to align the piercer with an underlying or overlying dose container.
