Abstract
A multi-layer medication carrier or blister card may comprise a plurality of layers. A support layer is provided with one or more openings to receive corresponding blisters formed in a blister layer. A backing layer is provided over the blister layer to form one or more enclosures capable of holding unit doses of a medication. Perforations provided in at least the blister layer define unit dose packages. Dimples may be provided in the blister layer within a boundary defined by the perforations, which dimples may be used to ensure subsequent ejection of each unit dose package. An adhesive-free region in the backing layer may be provided in alignment with the perforations defining each unit dose package to further ensure proper ejection. Additionally, a partial-depth cut in the backing layer may be provided in substantial alignment with each blister, thereby facilitating removal of the unit dose of medication.
