  • Patent number: 3982689
    Abstract: A mailer comprising a window envelope and an enclosure to be transmitted therein. The envelope is provided with first and second tear strips which are adhesively joined when the envelope is first sealed, but which can be torn off as a unit to leave a reusuable envelope. The enclosure is provided with a first removable portion to be retained by the recipient, and a second portion to be returned to the sender. It also includes two address areas laterally positioned to line up with the window of the envelope. As mailed, a first address area is in the window and the enclosure fills the envelope. Tearing off the removable portion of the enclosure reduces its size to fit the modified envelope, and the second area lines up with the envelope window. A modification of the invention forms a pulltab for convenience in opening the original envelope.
