Field of the Invention The present invention relates to an overlapped communication sheet that can be used as a postcard, a fixed or non-standard mail. 2. Description of the Related Art Japanese Laid-Open Utility Model Publication No. 49-33930 discloses a combined postcard in which a pair of paper sheets having the form of a postcard are detachably adhered with an adhesive. This combined postcard can display information such as communication on the inner surface of each piece of paper and attach it to a mail. However, in the above combined postcard, since the two pieces of paper are separate from each other, certain information on the sender side, for example, information including text, figures, graphs, photographs, etc. is continuously and in a list on the inner surface of both pieces of paper. It is difficult to display, and even if continuous display is performed on the inner surface of both paper sheets, both paper sheets are completely separated at the time of peeling and developing at the recipient side, losing the list of information and storing and filing. This is also inconvenient, and the inner surfaces of both pieces of paper cannot be used effectively continuously and in a list. In addition, in the above-mentioned postcard, both the paper pieces or one of the paper pieces have adhesiveness and tackiness on the inner surface even after the peeling and development of the paper pieces on the recipient side, so that the recipient side is uncomfortable and Storage and filing was difficult. [Problems to be Solved by the Invention] Accordingly, an object of the present invention is to make it possible to easily and continuously display certain information on both sides of a sheet at the sender's side, and to peel off both sides at the receiver's side. It is an object of the present invention to provide an overlapped communication sheet which can maintain the information at a glance without separating the two pieces of paper even after being unfolded, has no unpleasant stickiness, and is convenient for storing and filing. [Technical Means for Solving the Problems] The overlapped communication sheet according to the present invention is capable of peeling off both inner surfaces of a pair of transparent films during the folding of a pair of continuous paper pieces and showing adhesiveness after peeling. In this case, a pseudo-adhesive body formed by pseudo-adhesion is sandwiched so that the inner surface of each piece of paper and the outer surface of each transparent film facing it are completely bonded in a non-peelable manner via a heat-sensitive adhesive complete adhesive layer. In the above, a perforation or a slit may be perforated at a depth reaching the pseudo-adhesion portion of the pseudo-adhesive body at an edge of the one folded paper piece, which is opposite to the fold line portion, and furthermore, the perforation or A protective tape may be adhered on the slit so as to be peelable. [Operation] On the sender's side, after writing or printing a message, a photograph, and the like on the inner surface of the two continuous paper pieces, the continuous paper pieces are folded from the fold line portion across the pseudo-adhesive body, and both are completely bonded. In this case, the inner surfaces of the two transparent films are pseudo-bonded, and the inner surface of each piece of paper and the outer surface of each transparent film opposed thereto are completely bonded in a non-peelable manner via a heat-sensitive adhesive complete bonding layer. Note that the above-mentioned communication message and the following items such as the address may be continuously printed by a computer output device, and the paper piece therefor may have a known form as a computer output sheet. Pseudo-adhesion, as described above, the peeling of the inner surfaces of both transparent films after bonding is possible, and after peeling means a bonding mode that does not show adhesiveness to each inner surface, as such a pseudo-adhesive For example, the pseudo bonding mode described in Japanese Utility Model Application Laid-Open No. 62-9280 can be used, and both transparent films can be peeled off at the pseudo bonding portion at the boundary. Complete bonding means a bonding mode in which it is difficult or impossible to peel off the inner surface of each piece of paper and the outer surface of each transparent film facing it after bonding, and a heat-sensitive adhesive is selected as such a complete bonding layer. . The complete adhesive layer may be provided in advance on the outer surfaces of both transparent films in the pseudo-adhesive. Further, the heat-sensitive adhesive complete adhesive layer forms one of the transparent films, and the outer surface thereof is thermally and completely bonded to the inner surface of the paper piece facing the inner surface of the transparent film and the inner surface of the other transparent film facing the inner surface thereof. Pseudo-adhesion may be performed, and in this case, the other transparent film facing the transparent film made of the above-mentioned complete adhesive layer may be formed of a heat-sensitive adhesive complete adhesive layer as described above. Each constituent member of the pseudo-adhesive may be formed stepwise with respect to the paper piece, or some of the constituent members, for example, the transparent film or the like may be formed before cutting the paper piece. The address and name of the recipient and sender (
Name), and further, a communication message and the like are described in a usual manner, and are posted as an overlapped communication sheet. The overlapped communication sheet can be made into a normal postcard, a fixed form, or a non-standard-size mail by matching the conditions such as the size and weight of the overlapped communication sheet with a prescribed standard as necessary. The stacked communication sheet delivered, the two pieces of paper are peeled and developed on the recipient side,
It begins by peeling off the two pseudo-bonded transparent films. Since the outer surface of each transparent film and the inner surface of each piece of paper are completely bonded in a non-peelable manner via a heat-sensitive adhesive complete bonding layer, the two pieces of paper are separated from appropriate edges and simultaneously, The transparent film can be easily peeled. In that case, if one of the folded paper pieces has perforations or slits formed at an appropriate edge facing the fold line portion, the perforation is broken by bending that part, and That is, one piece of paper can be easily separated from the other piece of paper. The perforations or slits may be not only linear but also curved, for example, they may be provided linearly along the edge facing the fold line, and may be linear or curved at the corners It may be provided. In addition, it is preferable that the protective tape be releasably adhered on the perforations or slits of the paper piece, since it is possible to prevent spontaneous peeling of the two pieces of paper from the perforations or slits during the post-processing process or mailing. In that case, on the recipient side,
The protective tape may be peeled off before peeling and developing the two paper pieces. The transparent film from the pseudo-adhesive body remains on the inner surface of both strips that have been peeled and developed, but the exposed inner surface of the transparent film has no adhesiveness, and therefore has no stickiness due to finger touch, and the inner surface of both transparent films Re-adhesion is also not possible. Further, the information displayed on the inner surfaces of both paper pieces can be read without any problem through the remaining transparent film. In addition, the above-mentioned residual transparent film has the effect of improving the inner surfaces of both paper pieces after peeling and developing, and protecting them from external friction, contamination, moisture, and the like. Embodiment 1 FIGS. 1 and 2 are a plan view and an enlarged cross-sectional view taken along line II of an embodiment of the present invention, respectively. The cross-sectional views are exaggerated in the thickness direction. In the figure, a message, a photograph, etc. (not shown) are continuously provided on the inner surface of a pair of continuous paper pieces (1), (2).
