Automated mailer envelope addressing

摘要

An envelope for conveying an item from a sender to a recipient and back with a window and unique identifying indicia. The envelope comprises a base panel with a window, a sender address panel, and a recipient address panel. The sender address panel is affixed to the base panel by an adhesive region, which defines a pocket sized to accept an item. The adhesive region extends laterally on the base panel to ensure that a postal cancellation is not applied to an area overlying the item. The recipient address panel is joined to the base panel by a detachable joint. A fragile item may be conveyed from the sender to the recipient and back without damage to the item. The base panel includes indicia that uniquely identify the envelope among a plurality of envelopes. Reading the indicia assists in resolving inventory problems, for example, when unknown items are returned.
