发明名称 Security envelope
摘要 A security envelope has a body with an interior space. A flap attached to the body can close the interior space. This flap has a plurality of sequential panels. The envelope is adapted to allow each of the panels to successively fasten to the body. The panels are also adapted to be successively removed from the flap to open the envelope. Thus the envelope can be repeatedly closed and opened. The envelope can be used by fastening a first one of the panels to the envelope body to close the envelope. The envelope can then be opened by separating this first panel from the flap. The envelope can then be closed by fastening a second one of the panels to the envelope body. The envelope can then be reopened by separating this second panel from the flap.
