ABSTRACT:
A multiple compartment envelope is provided with each envelope adapted to carry identical information on their respective exteriors with a single writing. The envelopes are joined along their longitudinal edges and perforated along the joint for easy separation. Each envelope includes a flap with an appropriate adhesive for sealing purposes. After the user has deposited the desired contents into each envelope, one of the flaps may be folded to close the first envelope. This envelope is then folded along the perforated joint so that it lies above the other envelope. The flap of the other envelope is provided with a backing of carbon paper. This flap is folded over so that it contacts the back of the first envelope. Information written upon the flap will accordingly be carried upon both envelopes with a single writing. The envelopes may then be unfolded and sealed with the flaps. They are then separated along the perforation. An integral blank for forming the multiple compartment envelope is also disclosed.
