Abstract:
A Z-fold business form having a front face, a rear face, a top edge a bottom edge, and first and second lines of weakness disposed in spaced apart parallel relationship with said top and bottom edges and with each other, said form comprising:a first panel having a front face disposed on the front face of the form and a rear face disposed on the rear face of the form, said first panel being defined by the top edge of said form, said first line of weakness, and two parallel spaced apart side edges, each respectively extending between said top edge of the form and said first line of weakness, and having a plurality of discrete coactive adhesive areas disposed on the front face of the first panel in a predefined pattern adjacent said top edge and said side edges;a second panel having a front face disposed on the front face of the form and a rear face disposed on the rear face of said form, said second panel being defined by said first line of weakness, said second line of weakness, and two parallel spaced apart side edges each respectively extending between said first and second lines of weakness, said second panel having a plurality of discrete coactive adhesive areas disposed on the front face of the second panel in a predetermined pattern that coincides with the predetermined pattern of the coactive adhesive areas of said first panel when the form is folded along the first line of weakness and the front face of the first panel is brought into contact with the front face of the second panel, and a plurality of discrete coactive adhesive areas disposed on the rear face of the second panel in a predetermined pattern adjacent said first line of weakness and said side edges of the second panel;a third panel having a front face disposed on the front face of the form and a rear face disposed on the rear face of said form, said third panel being defined by said second line of weakness, said bottom edge of the form, and two parallel spaced apart side edges, each respectively extending between said second line of weakness and said bottom edge of the form, said third panel having a plurality of discrete coactive adhesive areas disposed on the rear face in a predetermined pattern that coincides with the predetermined pattern of the coactive adhesive areas on the rear face of said second panel when the form is folded along said second line of weakness and the rear face of the second panel is brought into contact with the rear face of the third panel;a third line of weakness formed only in said second and third panels extending between the first line of weakness to the bottom edge of the form in parallel relationship with said side edges, said third line of weakness defining separate return envelope and data portions, said return envelope being constructed in response to folding said form along said second line of weakness thereby forming a first closed side of said return envelope, bringing said rear faces of the second and third panels into mutual contact and activating said coactive adhesive disposed on the respective rear faces of the second and third panel, thereby forming second and third closed sides of said return envelope; anda selectively activated adhesive disposed on the rear face of a selected one of said second and third panels at a position along a fourth side of said return envelope portion, whereby after separation of said first panel from said second panel and separation of said data portion from said envelope portion, the fourth side of said return envelope is sealed in response to activating said selectively activated adhesive.
