ABSTRACT:
The envelope assembly comprises a rectangular front panel and a complementary back panel which together form an envelope for initial use in the delivery of an insert. First and second tear lines are formed across the two panels, respectively. The first tear line, formed across the front panel, is spaced inwardly from one side of the envelope a distance greater than the corresponding separation between the second tear line and the one side of the envelope. An insert formed within the envelope is secured between the front and back panels along said one side. By pinching the envelope and exerting a pulling force on it, from its opposite sides, the envelope can be burst. This separates the insert and a removable portion of the envelope along the first and second tear lines. The separation between the first and second tear lines exposes a portion of the back panel that extends outwardly from the first tear line. The extended portion of the back panel is foldable over the first tear line and front panel as a covering flap, enabling the envelope to be used a second time. Additional inserts can be included as part of the reusable envelope portion. The remainder of the envelope includes third and fourth tear lines of greater bursting strength than the first and second tear lines. These are used to separate the reused envelope in two for opening purposes.
