Abstract
Abstract A mailing envelope assembly adapted for machine processing is formed from a continuous web having a separable perforated strip on one edge for machine feeding. The envelope is separably joined to the feed strip, and has front and back panels joined at the longitudinal edge adjacent the feed strip by an adhesive stripe between one panel and a folded-under edge of the other panel. The other longitudinal edges of the panels are joined by an accordian or similar reentrant fold to permit expansion of the envelope without deformation of the panels. The panels are adhesively joined together at one end, and a flap with resealable adhesive and adapted to fold over the other panel is provided for sealing the envelope.

Claim 1
Independent Claim
308 words
In a mailing structure of the type including an envelope, and a strip attached thereto for machine feeding of the structure, and wherein the structure is formed of a single sheet of foldable material, the improvement wherein said envelope is comprised of a first generally rectangular panel having one longitudinal edge separably affixed to said strip, a second panel generally of the same size and substantially in alignment with said first panel, a narrow panel affixed to the longitudinal edge of said second panel adjacent said strip and folded under to lie between said first and second panels, said narrow panel being adhesively joined to the surface of said first panel, a longitudinally extending accordian fold joining the other longitudinal edges of said first and second panels, a transversely extending adhesive strip for joining aligned first ends of said first and second panels to thereby forming a pocket between said first and second panels, a flap foldably affixed to the other end of one of said first and second panels, and a reseal adhesive on said flap means, whereby said flap may be folded around the other of said first and second panels and sealed thereto, said accordian fold comprising a second narrow panel connected to each of said other longitudinal edges of said first and second panels by fold lines and said second narrow panel being divided into first and second longitudinal strips by a central longitudinal fold line, said transversely extending adhesive strip extending across one of said first and second panels and across said second narrow panel, said first longitudinal strip being adhered to said first panel and said second longitudinal strip being adhered to said second panel, the parts of said second narrow panel other than those across which said adhesive strip extends being free of the panels to allow expansion of the pocket.
