Abstract
Abstract Two layers of paperboard are sealed together. An intermediate area of one lyaer is embossed outwardly away from the other so that the other layer is out of contact with the one layer when the layers are sealed. This leaves the embossed area free of adhesion to the other layer so that it may be grasped for removal.
