Two-way mailing envelope and method of making and addressing the same

Abstract

A two-way mailing envelope formed from a single blank having generally rectangular front and rear panels integrally joined together along an upper panel fold line. A first closure flap is integrally joined along a first flap fold line to the lower edge of the front panel. The rear panel is shorter than the front panel and a second closure flap integrally joined along a second flap fold line to the lower edge of the rear panel. Mailing address indicia are provided on the front side of the envelope in a mailing address read area and oriented to be right side up when the panel fold line is at the top. Return address indicia are provided on the front side of the envelope and oriented to be right side up when the panel fold line is at the top. During the initial mailing, the second closure flap is tucked into the envelope and 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 at the first flap and the envelope is resealed for return mailing by folding the second closure flap on the rear panel upwardly and sealing the same against the front panel. The return address indicia is applied to the front of the envelope at a location such that at least the lowermost line of the return address extends into the mailing address read area during return mailing, 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 during return mailing.
