Abstract (en)
An envelope with contents especially for the mailing of confidential information, consists of a sealed mailing envelope (1) and an information carrier (2) incorporated inside the mailing envelope (1). The information carrier consists of a sealed internal envelope and the information to be mailed can be incorporated on the inside of the internal envelope (2). One or both sheets (16, 17) of the internal envelope (2) are therefore provided with copying means on the inside of the envelope. Along the surrounding edge of the mailing envelope (1) and/or the internal envelope (2) the sheets (3, 4 and 16, 17 respectively) of the envelope are bonded together. The adhesive layer between the sheets may partly take the form of two adjacent rows of adjacent glue spots (11 and 26 respectively). This enables on the one hand the evacuation of any air trapped in the mailing envelope (1) and/or the internal envelope (2) and prevents on the other hand that an unauthorized person gains access to the information incorporated in the internal envelope (2).
