Patent ID: 7073704

Claim:
A business form or mailer intermediate, comprising: a substrate sheet having first and second surfaces, first and second parallel longitudinal edges and first and second opposite ends; at least a first transverse fold line formed in said substrate perpendicular to said parallel longitudinal edges, said first fold line dividing said substrate into at least first and second panels; an address area on said first surface of one of said first and second panels, and a window opening defined in the other of said first and second panels, said address area and said window opening being positioned on said panels in alignment such that when said substrate sheet is folded along said first transverse line and said first surface of said first panel is brought into contact with said first surface of said second panel, said address area may be viewed through said window opening; and a pattern of adhesive on said first surface of said substrate, surrounding and substantially adjacent to at least one of said address area and said window opening, whereby folding said substrate at said first transverse line and bringing said first surface of said first panel into contact with said first surface of said second panel results in a seal around said window opening between said first and second panels, said adhesive being a pressure sensitive cohesive and said pattern of adhesive on said first surface of said substrate surrounding both said address area and said window opening, whereby folding said substrate at said first transverse line and bringing said first surface of said first panel into contact with said first surface of said second panel results in contact between the cohesive surrounding said address area and the cohesive surrounding said window opening, the bond between said cohesive on said first and second panels being less than the bond between said cohesive and said panels.
