Abstract

A blister pack for dispensing pills that is childproof yet senior-friendly. The blister pack includes a substantially tear-resistant housing that encloses one or more blisters contained on a blister sheet and surrounded by criss-cross grain material to provide cut or tear resistance in multiple directions. In one embodiment, the cavities of the blisters are positioned such that the pills are aligned at an angle with respect to the corresponding dispensing slots on the housing in their normal position. The blisters are detachably attached to a zipper strip on the blister sheet to prevent undesired rotation of the blisters. Upon removal of the zipper strip, the blisters may be twisted until their pills are substantially aligned with their respective dispensing slot. The blisters may then be depressed to remove the pills from the cavities of the blisters by pushing the pills through the foil sheet that covers the slots. In another embodiment, the blisters must be released and slid within a channel to align the pill with the dispensing slot to be released.
