Abstract
A push-through, blister card package for zinc-air batteries includes a cardboard support to which is sealed a transparent plastic foil with cup-shaped recesses for holding button cells. The battery bases, which are provided with air supply holes, are attached to a shared adhesive foil. When a battery is pushed through the support, which is perforated in the region for battery removal, the adhesive foil automatically detaches from the battery while remaining an integral part of the package.
