Abstract
An improved notch-forming tab enables a blister card package comprising a medicament to be easily opened by a user. The blister card package includes a container sheet having a well formed therein; a cover sheet laminated to the container sheet and spanning the well to form a blister containing the medicament between the cover sheet and the container sheet; and a plurality of slits defining a pattern comprising a pair of legs having respective converging and diverging ends disposed adjacent the blister. The converging ends of the pair of legs are separated from one another by between about 0.1 mm and about 1 mm and are spaced from the blister. The diverging ends of the pair of legs are spaced from an adjacent edge of the blister pack. Methods of opening this and other inventive blister card packages are also described herein.
