Abstract
Abstract A pill package of the type including child-proof features makes use of the standard blister card for mounting the pills. A plastic shield is constructed to provide a slidable mating relationship with the blister card in an unlocked position and the card and shield together defining locking means wherein both locked and unlocked positions can be assumed between the card and shield. As in all conventional blister cards, an access means construction is included, but in the structure of the present invention, the access means is unexposed when the card and shield are in the locked position.
