Abstract
A mailer type business form is formed by double parallel folding a single sheet of paper. The mailer may include a return envelope with a side opening edge, or it may comprise a seven page booklet, all of the pages attached together at one edge and most or all of the pages detachable from the booklet along a perforation line. One of the panels may be of a somewhat smaller width than the others, to allow elimination of one adhesive line, and one thickness of the final mailer, when the intermediate is double parallel folded.
Claims14
An intermediate for a mailer type business form comprising:
- a quadrate single sheet of paper having first and second faces, first and second parallel side edges, and first and second parallel end edges;
- first, second, and third fold lines parallel to said end edges, and dividing said sheet into first through fourth essentially equal sized panels, said first panel between said first end edge and said first fold line, said second panel between said first and second fold lines, said third panel between said second and third fold lines, and said fourth panel between said third fold line and said second end edge;
- a first adhesive pattern formed on one of said second and third panels first face for cooperating with the other of said second and third panels to form a return envelope when said sheet is double parallel folded about said fold lines:
- a flap fold line provided in one of said second and third panels adjacent first adhesive pattern, and parallel to said side edges, defining a fold-over flap for a return envelope formed when said sheet is double parallel folded about said fold lines;
- an activatable adhesive pattern disposed on said flap first face;
- a reply address area provided on the second face of one of said second or third panels;
- a second adhesive pattern formed on said first face of said fourth panel, and a third adhesive pattern formed on said second face of said first panel for holding said panels together when said sheet is double parallel folded about said fold lines;
- and
- lines of weakness formed in said panels adjacent, said second and third adhesive patterns for allowing detachment of said sheet thereat to allow opening of a mailer formed by double parallel folding said sheet about said fold lines.

A mailer type business form comprising:
- first, second, third and fourth substantially quadrate panels, each having essentially the same size, first and second side edges,and first and second end edges, and top and bottom faces, and said first panel underlying said fourth panel, and said second panel underlying said first panel, and said third panel underlying said second panel;
- a first adhesive pattern comprising first and second strips of adhesive parallel to and adjacent, but spaced from, said end edges, and a third strip of adhesive parallel to and adjacent, but spaced from, said first side edge, said strips acting between said second panel top face and said third panel bottom face to define a reply envelope;
- a flap fold line formed in said second panel, and a stub-forming line of weakness formed in said third panel, said flap fold line and said stub-forming line of weakness in alignment with each other and adjacent, but spaced from, and parallel to, said second side edge, said flap fold line forming a reply envelope flap;
- a strip of activatable adhesive provided on the face of said flap facing said third panel;
- reply address indicia provided on said reply envelope;
- second and third adhesive patterns holding said first panel to said fourth panel adjacent at least one edge thereof, and for holding said first panel to said second panel adjacent at least one end edge thereof;
- and
- lines of weakness formed in at least said first, fourth and second panels adjacent said second and third adhesive patterns on the opposite sides thereof from said adjacent end edges, to facilitate opening of said mailer.
