PCT No. PCT/DE85/00209 Sec. 371 Date Feb. 19, 1986 Sec. 102(e) Date Feb. 19, 1986 PCT Filed Jun. 20, 1985 PCT Pub. No. WO86/00276 PCT Pub. Date Jan. 16, 1986.A foldable letter that can be mailed. The latter encompasses a cut-out paper sheet, one surface of which is intended to receive communications or messages, and the other side of which is intended to receive postal indications, i.e., an address. This letter solves the double problem of finding a form that encourages the writing of letters in the face of the progression of electronic communication equipment and, on the other hand, of enabling easy opening of a folded and sealed letter without tearing it. The proposed solution relates to an appropriate carrier for handwritten communications, and a closure technique offering to the receiver an acceptable letter in its original size. The letter has a square basic shape and includes a rectangular field, the long sides of which are parallel, but not symmetrical, to one of the diagonals of the square. The four triangular closure flaps of the sheet are folded back to one face or side of the letter, and the edges of the flaps completely overlap and stick to one another. The side of the sheet that receives the communication is preferably lined on its entire surface, and parallel to two of the edges. Furthermore, the edges provided for the closure are provided on one side with detachable strips which, after the letter is opened, remain fixed to the nonwritten side. For this purpose, these strips are provided with a perforation. |
