Abstract: A blister pack includes a blister card having one or more cavities and a rib formed in the blister card, the rib having an inner surface, and a tether coupled to the inner surface of the rib. Ultrasonically welding the tether within the inner surface of the structural rib provides for an increased bond surface area and increased strength of the couple without sacrificing valuable surface area on the blister pack.

Abstract: A blister pack includes a cavity sheet including at least one product blister and an access blister associated with each of the at least one product blister, and a child resistant backing coupled to the cavity sheet, the child resistant backing including a weakened pattern corresponding with each of the at least one product blister formed in the cavity sheet, wherein the access blister includes a generally V-indent member configured to initiate a separation of the weakened pattern. The V-indent member focuses forces to allowing easy access to the product blister by adults, including seniors, while maintaining child resistant standards.
