Abstract
The present invention is a system for opening blister packages. Generally, a cover attachment is fixed to a blister card. Buttons or tabs on the cover attachment are aligned with individual blisters on the blister card and have piercing edges or attachments. A user presses the buttons or lifts tabs and a cover layer over the blisters is pierced. The buttons or tabs are then moved or raised to allow the user to access the contents of the blister by conventional means. Embodiments include hinged tabs, slideable attachments, clamshell-like covers with moveable carriages, rotatable arms with piercing attachments, locking tab mechanisms, and flexible tethered tool devices. A variety of different blister configurations can be used. Additionally, the blister card attachments render the blister card/pack child resistant despite being easier to open.
