Abstract
A compartmented envelope is disclosed which includes two compartments front-to-back formed by non-overlapping elongated end closure flaps. The front compartment includes a window behind which a preaddressed item might be placed and the envelope is arranged so that the window compartment is in front of the envelope stuffer when the preaddressed item is stuffed. The envelope panels are preapplied with a pressure sensitive adhesive that will only adhere to itself in a pattern so that items smaller than the envelope itself can be inserted and locked in place within the front compartment while the second compartment is available for larger more bulky items. In other embodiments, the envelope includes an unsecured end closure flap that may be opened for postal inspection when the envelope is carrying both first and third class matter, and/or a means for gaining access to one compartment independently of the other.
