The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card. Upon the application of sufficient force, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the foil layer and the scored exit port.
