Abstract: A child resistant tablet package accommodates low density pharmaceutical tablets. The package includes a blister tray having a plurality of blister depressions which accommodate the low density porous pharmaceutical tablets. The blister tray further includes a frangible tray extent spaced adjacent to each blister depression. The frangible tray extent may be manually punctured through the surface of the blister tray. A planar lid is removably sealed over the blister tray and encloses the tablets within the blister depressions. The blister lid includes frangible cover extents overlying each of the frangible tray extents. The cover extents and the tray extents may be frangibly displaced so as to establish a graspable peel tab to facilitate peelable removal of portions of the cover from the overlying disposition with respect to the blister depressions so as to expose the tablets for dispensing.

Abstract: A childproof covering of a blister pack, e.g., one used to contain and vend tablets of medication, is heat-sealed to an element containing recesses for containing the tablets. The heat sealing disposes a frangible foil over the tablets, and provides two successive peelably adhered layers, preferably of a transparent plastic material, thereover. These two layers are each provided with a series of perforations in respective different patterns. Such a structure prevents a young child from biting through to the medication yet enables an older child or adult to successively peel away portions of the two plastic films to, thereafter, apply a force to the medication to rupture the foil in known manner. The adhesive layers by which the two plastic films are adhered to the frangible foil may include an ingredient which is harmless but will taste unpleasant to a young child and discourage further efforts to access the medication.
