Two-way mailing envelope

Abstract

A two-way mailing envelope formed from a single blank having generally rectangular front and rear panels integrally joined together along an upper fold line, and first and second closure flap integrally joined to the lower edges of the respective front and rear panels along lower fold lines. Mailing address indica are provided on the front side of the envelope in a mailing address read area and a return address is provided on the front side of the envelope at a level above the mailing address. During the initial mailing, the first closure flap on the lower edge of the front panel is folded upwardly and sealed to the rear panel of the envelope. The envelope is opened by rupturing the rear panel along the first flap fold line and the envelope is resealed for re-mailing by folding the second closure flap on the rear panel upwardly and sealing the same against the front panel. A second closure flap is dimensioned so that it covers the original mailing address while leaving the return address on the front of the envelope exposed. In one embodiment, a re-mailing address is printed on the second closure flap. In another embodiment, the return address indicia is printed on the front of the envelope so that at least the zip code of the return address extends into the mailing address read area, and the second closure flap is dimensioned so that it covers the original mailing address but leaves the return address indicia exposed for sensing by automatic mail processing equipment.
