Abstract

The single-ply, multi-panel envelope form comprises a pair of coplanar, envelope-defining panels disposed in end-to-end, spaced relationship and at least one intermediate panel disposed between and end-connected relationship with said envelope-defining panels wherein the opposite side edges of each intermediate panel are disposed inwardly of the corresponding side edges of the envelope-defining panels. The side edges of the envelope-defining panels of each form are disposed in contacting, sealed relationship when the panels of each form are zig-zag folded into envelope-defining relationship permitting removal of the intermediate panel from the interior of the envelope through access means provided in one marginal edge thereof. The forms of the present invention are readily produced in an end-to-end connected series from a continuously advancing web of sheet material which is transversely subdivided into a plurality of end-to-end interconnected forms, each of which are adapted to be sequentially zig-zag folded into sealed, envelope-defining relationship, and thereafter severed from the series as individual forms. A stuffer-insert such as a circular or the like may be inserted in the interior of the envelope prior to sealing thereof.
