  • Patent number: 5358118
    Abstract: A stepped-edge blister pack for containing and dispensing unit doses of medication such as capsules, tablets, caplets or fast-dissolving dosage forms (FDDF) is disclosed. The invention is comprised of a base sheet and a substantially planar lidding sheet. The base sheet has a plurality of blister compartments and a plurality of steps along its edges, one step being adjacent to each blister compartment. The substantially planar lidding sheet is peelably sealed to the base sheet except at extended edge regions, thus forming edge peel tabs, and the lidding sheet is scored with lines of weakening about each blister compartment. The steps along the edges underlay the unsealed extended edge regions of the lidding sheet, thus providing a series of finger accesses to thereby ease the process of grasping a given edge peel tab and ultimately opening a given blister compartment.
