Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a covert information carrier such as a postcard or a card in which information to be concealed (hereinafter referred to as covert information) is displayed on a releasably adhered overlapping surface. The present invention relates to a concealed information carrier which is made releasably adhered by a releasable adhesive after being adhered. The concealment information in this specification is not necessarily limited to information having confidentiality.

[0002]

[Prior Art]

 Conventionally, concealed information holders such as postcards and cards with various configurations have been known, but they are usually not bonded and can be bonded by applying a predetermined pressure. In the case of the concealed information carrier that is adhered, the thin concealed information carrier is laminated and adhered so that the concealed information carrier does not become thick.

[0003]

[Problems to be solved by the device]

 For this reason, this type of concealed information carrying body of the conventional example has a so-called weak waist, which easily curls and is inconvenient to handle. It is an object of the present invention to provide a hidden information carrier that eliminates such inconvenience.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the concealment information carrier of the present invention is formed by stacking a plurality of paper pieces, and information to be concealed is displayed on a predetermined superimposing surface. It becomes possible to adhere by applying a predetermined pressure without adhering, and after adhering, it is releasably adhered with a releasable adhesive, but does not print the information on at least one of the paper pieces forming the overlapping surface. The surface is provided with a curl prevention layer. The anti-curl layer is composed of, for example, a synthetic resin film layer or a varnish layer.

[0005]

[Action]

 By providing the anti-curl layer, the so-called stiffness becomes strong and the curl does not occur. Further, since the curl prevention layer is provided on the surface on which information is not printed, it does not become an obstacle when printing concealed information and the like.

[0006]

【Example】

 Hereinafter, a preferred embodiment in which the present invention is applied to a postcard will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a schematic cross-sectional view of a postcard, FIG. 2 is a plan view of the front side thereof, FIG. 3 is a perspective view in a partially peeled state, FIG. 4 is a cross-sectional view of a postcard paper piece, and FIG. It is the top view.

First, the structure of the postcard sheet piece will be described with reference to FIGS. 4 and 5. In the postcard sheet piece 1, an upper paper piece 3 and a lower paper piece 4 of the same size are connected via a folding perforation 2. Become. The surface sides of the upper paper piece 3 and the lower paper piece 4 are releasably adhered to each other, and the surface of the lower paper piece 4 is a concealment information printing surface on which the concealment information entry field 5 is preprinted. On the surface of the top paper piece 3, a guide text 6 related to the concealment information 12 (see FIGS. 1 and 3) to be printed later is printed in advance. As can be seen in FIG. 4, a guide sentence 6 is printed on the surface of the upper paper piece 3, and a synthetic resin film layer 7 as an anti-curl layer is attached by an adhesive 8. Then, the synthetic resin film layer 7 and the surface of the lower paper piece 4 are not usually bonded, but can be bonded when a predetermined pressure is applied, can be peeled off after bonding, and can be printed and printed. Pressure sensitive adhesive 9 is applied.

The synthetic resin film layer 7 is formed of polyethylene or polypropylene to a thickness of 10 μm to 40 μm, preferably 15 μm to 40 μm, and more preferably 15 μm to 20 μm. The pressure-sensitive adhesive 9 is obtained by terpene resin-based natural rubber latex obtained by copolymerizing 100 parts by weight of natural rubber with 2 parts by weight of styrene and 10 parts by weight of methacrylic acid. It is preferable to add 20 parts by weight of silica gel having an average particle size of 5 μm to 5 parts by weight of the tackifier.

As shown in FIG. 5, a cutting perforation 10 that is broken when peeled off is provided at a lower corner portion of the upper paper piece 3 opposite to the folding perforation 2. As shown in FIG. 2, the back surface of the top paper piece 3 is an address display surface, and the destination information 13 is printed later. Then, along with the lower edge of the destination display surface, along with an arrow pointing to the perforation 10 for cutting, a description 11 "Bend the perforation, break and peel off" is printed in advance.

Next, the composition of a postcard, which is a hidden information holder, created using the above-mentioned postcard sheet piece 1 will be described together with the creation procedure. While transferring the postcard paper piece 1 in the state shown in FIGS. 4 and 5 in a predetermined direction by using an appropriate transfer device (not shown), the bottom paper piece 4 is transferred by a double-sided printer which is an output device of a computer (not shown). Concealment information on the front side: Predetermined concealment information 12 is printed in the entry field 5, and destination information 13 (see FIGS. 1 to 3) is printed on the back side of the cover sheet 4. It is possible to print with a normal printer without using a double-sided printer, but in this case it is necessary to reverse the front and back sides and print twice. Further, a folding device (not shown) is also used to make a double-folded state such that the overlapping surfaces are overlapped at the folding perforations 2 and a predetermined pressure is applied from above and below by a pressure roller (not shown). Adhesive conditions are applied to the pressure-sensitive adhesive 9 and the superposed surfaces are adhered to form a postcard 20 in which the concealment information 9 shown in FIGS. 1 and 2 is concealed.

In this state, the postcard 20 can be posted in the same manner as a general postcard. Since the postcard 20 is provided with the synthetic resin film layer 7, the postcard 20 becomes so stiff and hard to curl. On the other hand, when the addressee who has received the postcard 20 breaks the perforation 10 for cutting of the lower paper piece 3 according to the explanatory note 11 printed on the upper paper piece 3, the broken end of the upper paper piece 3 causes the cut end of the lower paper piece 3 to move. It will be in the state of peeling from. Next, the addressee can put his / her finger on the above-mentioned broken end and peel off the upper paper piece 3 from the lower paper piece 4 as shown in FIG. 3 to visually confirm the concealed concealment information 12.

The present invention is not limited to the above-described embodiment. For example, the postcard piece 1 may not be in a single piece state but may be in a continuous state at the beginning. The postcard 20 can be created by folding the postcard paper piece 1 in two, folding it in three in a Z shape, or cutting and stacking it. May be configured to overlap each other. Further, the synthetic resin film layer 7 as the anti-curl layer may be formed of synthetic resin other than polyethylene and polypropylene. In addition to the synthetic resin film layer 7 being the anti-curl layer, the varnish has a thickness of 10 μm to 40 μm. It may be formed by applying to. Furthermore, it goes without saying that the present invention can be applied to various cards in addition to the postcard 20.

[0013]

[Effect of the device]

 As is apparent from the above description, according to the present invention, by providing the curl prevention layer on the surface of the overlapping sheet that does not become the printing surface, the desired printing operation can be performed smoothly while the hidden information possession is maintained. The body is so stiff that it is difficult to curl.
