ABSTRACT:
A two-ply cover for a writing tablet is formed by a unitary die-cut blank of sheet material having an inner panel and an outer panel folded approximately along a medial fold line and sealed at their outer edges to form a pocket therebetween. The inner edge portions of the two cover panels are adhesively bonded to the back, upper edge portion of the tablet. The bonded edge portion of the outer panel corresponds to the width of the cover while the bonded edge portion of the inner panel consists of a tab substantially narrower than the cover. The tab and a fractional part of the outer panel's bonded edge portion are superposed with an adhesiver interface between the back of the writing tablet and the inner surface of the tab and the edge portions of the outer panel that are not coextensive with the tab.
