ABSTRACT:
A specially designed envelope and a companion envelope opening mechanism are disclosed which operate in combination such that the envelope is automatically opened in a single motion to expose the contents of the envelope for high speed machine or manual extraction. The envelope includes longitudinally disposed slits which run from a rear side fold line to points disposed along the length of the envelope along top and bottom fold lines. Disposed on the front wall of the envelope perpendicularly to the fold line slits are connecting members, a plurality of additional slits and a plurality of apertures. The plurality of apertures are disposed between the additional slits. The apertures provide openings into which extracting "fingers" of the automatic envelope opener enter the envelope during the envelope opening process to free a flap in the return address portion of the envelope to thereby expose the envelope contents.
