ABSTRACT:
A two-way mailing envelope for both first and return mailing is disclosed, which has top, bottom and side edges and comprises a pair of panels foldably connected to each other along one fold line extending along the bottom edge and folded over one another to form a first mailing envelope, first adhesive means adhesively fastening in superimposed relationship side edge portions of the panels, and first and second side tear strips severable along respective first and second tear lines and including the side edge portions. A first adhesive closure flap is foldably connected to the one panel along another fold line extending along the top edge, the first adhesive closure flap being foldable along the other fold line to seal the first mailing envelope. Third and fourth tear lines are equidistantly spaced inwardly and outwardly from the other fold line to define a third tear strip when the first adhesive closure flap is folded to seal the first mailing envelope such that the sealed first mailing envelope is adapted to be converted into a return envelope by tearing off the first, second and third tear strips and by refolding the panels inside out along the one fold line to form the return envelope. Second adhesive means are provided inwardly of and adjacent the edge portions of one of the panels for adhesively fastening together the panels when refolded inside out. A second adhesive closure flap is foldably connected to the other panel along a further fold line extending parallel to the one fold line, the second adhesive closure flap being folded along the further fold line to nest inside the first mailing envelope and being unfoldable to seal the return envelope when formed.
