Description:
This application claims the benefit of Provisional Application 60/361,379, filed Mar. 1, 2002. 

   BACKGROUND OF THE INVENTION 
   U.S. Pat. Nos. 5,836,622 and 6,257,624, which are hereby incorporated by reference, teach the ability to print a duplex form with a single pass through a simplex non-impact printer. This allows the user to produce a duplex Postcard without the need for pre-printing. However, these previous patents do not provide for printing of three post cards from a single form. 
   Other forms that are commercially available provide three postcards on a standard paper size and are printable on the installed base of non-impact printers for purposes of economy and throughput. These products are known in the industry as “3-up” forms. However, these commercially available 3-up products require pre-printing or processing on a duplex printer. 
   What is needed is a multiple transaction Postal form, utilizing the least amount of materials, which will process on the installed base of non-impact printers, and which does not require preprinting in order to provide variable printed information on the front and back faces of the form. 
   SUMMARY OF THE INVENTION 
   The subject invention concerns a more efficient mailing form comprising a post card or other printable document wherein addresses or other variable information can be printed on both front and back faces of the document by a single pass through a simplex printer. The subject form assembly comprises a folding flap, printable on the front face of the assembly and is provided for printing of variable information such as the return address. The folding flap is preferably approximately ⅓ the total height of the post card, therefore saving area on the form assembly and allowing up to three post cards of size and thickness acceptable for United States Postal Service (USPS) specifications to be provided on a single legal size (8.5″ by 14″) sheet: up to two post cards of USPS-acceptable size and thickness on a single A 4  sheet, or one post card of USPS-acceptable size and thickness on a single 8.5″ times 5.5″ sheet, which will advantageously pass through an envelope feeder of a conventional home or home-office non-impact printer.

   DETAILED DESCRIPTION OF THE INVENTION 
   The subject invention comprises a two-ply form.  FIG. 1  is a plan view of the front (outer) face of the front ply  120  of a 3-up embodiment of a form assembly according to one embodiment of the invention. The first or front ply  120  is die-cut  102  or perforated, which form tear-lines for providing a plurality of sections. In this example, three identical sections are denoted A, B, and C. It important to note that the number of sections is exemplary only and one or more sections have been shown to be used advantageously with the present invention. Each section has a post card forms  104  and removable labels  106  and  108  typically formed by die-cuts  114  in the front ply  120 . The post card form  104  includes a foldable flap  110 , which has a perforated fold line  112 . The front ply  120  has an inner back face  200 . The postcard optionally includes one or more side tabs  142  which are used to attach the post card to an item being mailed. 
   Turning now to  FIG. 2 , shown is a plan view of the back (inner) face  200  of the top ply of a 3-up embodiment of a form assembly according to one embodiment of the invention. Numbering throughout the figures has been shown to correspond to the front face of the front ply  120  with only the preceding digit changing e.g.  2 . For example, the inner face of the post card  204 , removable labels  206  and  208 , foldable flap  210  and fold line  212  are shown. The back face  200  has adhesive material patternly disposed thereon over substantially the entire surface of the inner face (not shown), except in the substantially rectangular shaded areas  214  as shown in  FIG. 2  which is adhesive-free. This adhesive free area  214  forms adjacent the fold line  212  on the back (inner) face  200  of post card  204 . 
   Turning now to  FIG. 3 , shown is a plan view of the inner face  300  of the back ply  320  of a 3-up embodiment of a form assembly with three identical sections separated by die cuts  302 , according to one embodiment of the invention. The second or backing ply  320  has a first inner face  300  which meets the back face  200  of the front ply  120 . The backing ply  320  has adhesive release material disposed thereon substantially as shown as shaded area  330  in FIG.  3 . Note the back ply area  304  is used in conjunction with the front ply  120  to form a portion of the post card  104 . 
   Turning now to  FIG. 4 , shown is a plan view of the back (outer) face  400  of the back ply  320  of a 3-up embodiment of a form assembly according to one embodiment of the invention. The back face  400  of the backing ply  320 , shown in  FIG. 4  can have patterned coloring or shading as desired. A back area  404  forms the back face  400  of the post card  104 . This back area  404  of the post card  104  is typically where the addressee (i.e. sender or “return to”) information is placed on a United Stated Postal Form  3811 . A backing strip  410  on the back ply  320  is preferably about twice the height of the fold-over flap  110  so that when the flap is folded, the postcard is uniform in thickness with no possibility of an address label being sheared off in postal processing. In one embodiment, the back strip  410  is initially attached with glue stripes to the top ply  120  to make the back strip  410  portion of the ply  320  removable from the front ply  120 . This “striping” disposition of the adhesive or glue allows maximum contact of the folded flap to non-silicon areas to produce a relatively permanent bond, while making the resulting bond more flexible and to allow any trapped air to escape when the plies are pressed together. 
   Additionally, processing steps are reduced to a minimum. After the multiple form is separated into individual transactions at the tear lines, the form is curled to pop the post card from the backing, and then folded and affixed to the back, outer face of the card to provide an address area on that face. 
   Generally, the invention has been described in its preferred form or embodiment with some degree of particularity, it is to be understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
