ABSTRACT:
The multi-leaved tablet of this invention consists of leaves with corresponding surface portions adhesively interconnected and with corresponding surface portions free to fold relative to adjacent leaves. The leaves are of predetermined configuration and are die cut from a plurality of panels arranged so that they overlap. An area of adhesive interconnects portions of the surfaces of adjoining panels. This area has a rectilinear peripheral segment, and each die-cut leaf includes at least a portion of the rectilinear peripheral segment of the adhesive area. The rectilinear peripheral segment of the adhesive area is coincident with the folding axes of the leaves.
