Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a piece of polymeric paper folded in half, and more particularly to a piece of polymeric paper used as a postcard or card with concealed communication information.

Conventional technology In the past, various types of communication information, including the addressee, were printed on two or three consecutive pieces of paper using a printing device connected to a computer, and these pieces were superimposed to create an envelope. It is known to hide the desired conveyed information by doing so. However, mailing costs for sealed letters are higher than for postcards, and if a large number of sealed letters have to be mailed, the difference in cost can become enormous. Therefore, it can be used as a postcard, and
Continuous forms disclosed in Japanese Utility Model Publication No. 1832/1983 and Japanese Utility Model Publication No. 1833/1987 have been proposed as polymerized paper strips capable of concealing desired transmitted information. In addition, a card form for creating a card or a certificate by printing or printing information to be hidden on one of two pieces and superimposing it on the other is disclosed in Utility Model Publication No. 54-41679. ing.

Problems to be Solved by the Invention However, the above-mentioned conventionally proposed continuous forms and card forms have the disadvantage that the amount of information that can be concealed is extremely small. The disadvantage of this is that if the part of the communication information that is printed or printed on one of the overlapping pieces of paper is glued to the other paper piece, this communication information cannot be directly perceived by the human eye. This is due to the fact that adhesive cannot be applied to the parts. In other words, in order to polymerize two or more pieces of paper and use them as a single postcard or card, it is necessary to reliably adhere most of the polymerized surfaces, but in the conventional example, the portion of the communication information that should be hidden is If it is set wide, the area occupied by the non-adhesive part becomes large and the polymerization and integration become incomplete, so the area of the transmission information to be hidden must necessarily be small.

The present invention can eliminate such drawbacks in the conventional example and increase the area occupied by the transmission information portion to be hidden. The purpose is to provide polymerized paper strips that can be used as postcards and cards.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a polymeric paper strip that is folded in half and glued together, and the bonding surface of the polymerized paper strip is provided with a buffer on at least one side. Transparent or translucent film made of synthetic resin such as polyethylene film, polypropylene film, or postester film, or processed paper such as tracing paper or glassine paper, etc., is used to conceal the information to be transmitted. While the communication information is imprinted or printed on one adhesive surface and is glued non-peelably to the other adhesive surface, there is no need to hide it on at least one of the exposed surfaces of the polymeric paper strip. It is printed or printed information. As a means for removably adhering, for example, a weak adhesive such as a temporary adhesive may be used, and as a means for releasably adhering, for example, a pressure sensitive adhesive or the like may be used. A permanent adhesive such as a heat-sensitive adhesive or heat welding may be used.

Function While the polymerized paper strips are integrated and used as postcards and cards, the film interposed between the adhesive surface on which the communication information to be hidden is printed or printed has a weak adhesive force to one adhesive surface. By being peeled off from the adhesive or the like, the communication information to be hidden becomes visible through the film, and the print or printed portion of the communication information to be hidden is protected by the film.

Embodiments Hereinafter, preferred embodiments in which the present invention is applied to postcards will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the front side of a paper strip that is folded in half in a pre-polymerization state. Marginal parts 3 with transfer pinholes 2 are provided on both sides of the paper strip 1, while marginal parts 3 are provided in the center. A folding perforation 4 is provided, and the upper paper piece 5 and the lower paper piece 6 are divided and connected by the folding perforation 4. Further, on the surface of the upper paper piece 5, an addressee's name 7 is printed by a double-sided printer linked to a computer.

FIG. 2 shows the back side of the paper strip 1 that is folded in half before superposition. Communication information 8 and 9 to be transmitted, such as the deposit balance, the amount of the time deposit, and the maturity notice, etc., are printed.

As is clear from FIG. 3, the entire back surface of the lower paper piece 6 is coated with adhesives such as natural rubber, synthetic rubber, vinyl acetate-vinyl chloride copolymer, etc., and rosin derivatives, terpine resin, etc. A transparent adhesive 10 containing additives, fillers, anti-aging agents, etc. is applied over the entire surface. This adhesive 10
is always sticky under normal conditions and its adhesive strength is weak. A transparent film 11 made of, for example, polyethylene film is adhered to the opposite side of the adhesive 10 from the lower paper piece 6 so that it can be peeled off by applying a repelling force of a predetermined value or more. Further, on the opposite side of the film 11 from the adhesive 10, a transparent permanent adhesive having a stronger adhesive strength than the adhesive 10 is applied, for example, without adhesion under normal conditions, but when applied with a pressure of more than a predetermined value. A transparent pressure-sensitive adhesive 12 that adheres when applied is applied over the entire surface.

FIG. 4 shows that each marginal part 3 of the paper strip 1 has been cut out, and the upper paper strip 5 and the lower paper strip 6 are cut out at the perforation 4.
Fold them so that their back sides face each other, and apply more than a certain amount of pressure to adhere and integrate them.
This shows the state in which the overlapping paper piece 13 is formed.
In this state, the overlapped paper piece 13 with the addressee 7 exposed can be used like a normal postcard, and the communication information 8 and 9 to be hidden cannot be seen from the outside.

When the addressee receives the overlapping paper piece 13 in such a state and wants to see the hidden communication information 8 and 9, he opens the overlapping paper piece 13 and removes the upper paper piece 5.
All you have to do is separate it from the lower piece of paper 6. Then, since the adhesive force of the pressure-sensitive adhesive 12 is stronger than that of the adhesive 10, as shown in FIG. It is peeled off from the piece of paper 6. Therefore, the transmission information 8 to be hidden printed on the back side of the upper paper piece 5 can be read through the transparent film 11 and the pressure-sensitive adhesive 12, respectively, and the communication information 8 to be hidden printed on the back side of the upper paper piece 5 can be read through the transparent adhesive 10. The transmission information 9 to be hidden printed on the back side of 6 can be read.

In the embodiment described above, the adhesive 10, the film 11, and the adhesive 12 are placed on the back side of the lower paper piece 6.
The upper paper piece 5
The layer may be provided on the back surface of the substrate, or the order of stacking may be reversed. When the order of lamination is reversed, it is desirable to provide a release paper to cover the adhesive 10. In addition, communication information that should be hidden 8, 9
may be displayed only on the back side of either the upper paper piece 5 or the lower paper piece 6, or various information such as advertising text that does not need to be hidden may be displayed on the front side of the lower paper piece 6. Furthermore, although the pressure-sensitive adhesive 12 is used as a permanent adhesive with strong adhesion, the present invention is not limited to this; heat-sensitive adhesives, moisture-sensitive adhesives, etc. do not adhere under normal conditions and are constant. It is also possible to use other adhesives that bond when the following conditions are given, and in addition, it may be bonded irremovably by means such as thermal welding. Further, it is also possible to perform a peeling-facilitating treatment such as coating the contact surface of the film 11 with the adhesive 10 with silicone resin.
This process is particularly effective when using processed paper. The adhesive strength of the parts to be releasably and non-releasably adhered does not need to be uniform, and may be partially strong or weak. Further, instructions for peeling off the overlapping paper piece 13 may be provided by printing on the surface side of the lower paper piece 6, or an unadhered portion may be formed at a predetermined corner, or a slit may be formed at a corner of the lower paper piece 6 to perform the peeling operation. It may be configured so that it can be easily performed.

Effects of the idea As is clear from the detailed explanation above,
According to the present invention, communication information to be concealed is printed or printed on one or both of the adhesive surfaces of a piece of polymeric paper folded in half and bonded together, and this communication information to be concealed is printed with a transparent or translucent film. While the film is coated and adhered, it is removably adhered to the other adhesive surface, and information that does not need to be concealed is printed or printed on at least one of the exposed surfaces. Communication information that would be inconvenient if it were known to a third party can be concealed without using a sealed letter and can be safely notified without being known to a third party, and the recipient can easily remove the polymerized paper piece from the film. It can be peeled off to make a two-page spread, and the transmitted information can be easily confirmed. Furthermore, since the polymerized paper strip is polymerized into two folds,
Overlap bonding can be performed accurately and easily without positional deviation. Furthermore, since one side of the overlapped paper pieces is connected by bending, even when handling a large amount of paper such as postcards, positioning operations such as butting can be easily performed on the connected sides.
Furthermore, since the transmitted information to be hidden is covered with a film after the polymerized paper piece is peeled off, there is no fear that the transmitted information to be concealed, such as the deposit balance, will be tampered with, and it can be safely protected and stored. can be done easily and safely.
