Abstract

A powder storage and delivery system for a drug powder inhaler (20) has a carrier disk (46) with a blister shell (54) sealed by a shear layer (56). A tab (48) is adhered to the shear layer (56), underneath the blister shell (54). The carrier disk (46) is placed into a dry powder inhaler (20). An actuator (80) pushes against the tab (48), causing the shear layer (56) to tear away, releasing the powder drug contents (62) from the blister into the dry powder inhaler (20). A disk carrier (130) has bursting blisters (132) with a brittle blister shell (132) sealed with a foil lid (150), and covered by a plate (136). An actuator (160) moves against the plate (136), causing the plate (136) to buckle and the blister shell (132) to burst open, releasing powdered drug (62) into the dry powder inhaler (20).
