BACKGROUND OF THE INVENTION

Many medications are packaged in blister packs comprising a plurality of deformable cavities formed into a flexible foil. Doses of medicaments are received in the cavities which are sealed by a film. In most cases, to release a dose of medication, force is applied to the blister pack and is transmitted to adose, which breaks the film for dose removal by the user. These blister packs are convenient and widely used. Unfortunately, it is also easy for unsuspecting children to release drug doses from blister packs, whereby they can be poisoned by ingestion of the drug.

US 2002/0153276 A1 discloses a child safe package for tablets and similar pharmaceuticals comprising a blister pack having depressed cavities, and an apertured wall portion. Said packaging is arranged to allow movement of said blister packaging between an open position and a closed position, in which closed position the cavities are displaced from the openings, and in whose open position the cavities are aligned with the openings, the openings are sized to allow the passage of a pill through them. The openings in the wall portion are covered by a tear strip which is removed before pushing the blister package from the closed to the open position.
