Abstract:
A V-fold pressure seal form, comprising:a sheet having a face, a back, at least one first fold line, a first panel and a second panel separated by said first fold line, each panel having a top edge, a bottom edge, a first side edge and a second side edge;said sheet having first and second opposite longitudinal edges perpendicular to said first fold line;first and second longitudinal lines of weakness formed in said sheet parallel to and adjacent, but spaced from said first and second longitudinal edges, respectively, said lines of weakness defining with said longitudinal edges a first and a second longitudinal margin portion in each panel;a first horizontal pattern of cohesive parallel and adjacent to said top edge on the face of said first panel;a second horizontal pattern of cohesive parallel and adjacent to said bottom edge on the face of said second panel;a first longitudinal pattern of cohesive disposed in said first longitudinal margin portions in said first panel;said first longitudinal pattern of cohesive having individual configurations, each configuration having a first line AB having end points A and B and a second line CD parallel to said first line and having end points C and D, said lines are parallel to said longitudinal edges;a third line BD having end points B and D which makes an angle ABD with said first line which is less than 90 degrees;a fourth line AC having end points A and C;a second longitudinal pattern of cohesive disposed in the first longitudinal margin portion in said second panel, said longitudinal pattern being a mirror image of the first longitudinal pattern such that when the first and second panels are folded about said fold line the individual configurations of said longitudinal patterns of cohesive conform and the first horizontal pattern of cohesive and the second horizontal pattern of cohesive conform.
