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.
