  • Patent number: 5899333
    Abstract: This invention pertains to packaging wherein the package comprises a blister member bonded to a substrate member. The blister member has a product-holding cavity having a sidewall, and is secured to the front surface of the substrate member by a bond line extending generally about the product-holding cavity. A tear strip is defined in one of the blister member and the substrate member. The tear strip comprises an opening tab having a distal edge disposed outwardly of the side wall at or adjacent a free edge in the blister card, and lines of weakness extending from approximately the distal edge inwardly on the blister card. The tear strip facilitates the creation of an opening in the blister card to provide access to the product-holding cavity. The tear strip is devoid of fixed bonding to the other of the substrate member and the blister member to allow for easy activation of the tear strip to open the package.
