BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention displays information to be concealed and concealed (hereinafter referred to as concealment information) on a superimposing surface which is folded in two or three and is superposed, and the superimposing surface displaying the concealment information. The present invention relates to a concealed information carrier sheet for creating concealed information carrier such as postcards and various cards which are releasably adhered.

[0002]

2. Description of the Related Art Heretofore, in this type of hidden information carrier sheet, generally, a folding portion is formed with perforations in order to ensure an easy and reliable stacking operation in a folding machine. is there.

[0003]

Generally, in order to create a large number of concealed information carriers such as postcards and various cards, a printer is used to output information to a concealed information carrier sheet and then a folding machine. A method is used in which peeling is performed by easily and surely superimposing them through the perforations of the folding part. However, the paper dust and the protrusions caused by the perforations for folding formed on the sheet for the hidden information carrier with an adhesive may affect the printing quality and the running property of the printer, or may not be adhered to a predetermined amount without being normally adhered. When a pressure-sensitive adhesive is used that can be bonded, and a peelable adhesive is used after the bonding, when the sheets are folded and the overlapping surfaces are bonded to each other to create the hidden information holder, the perforation is applied by pressure. The situation occurs that the part is partially or totally broken. Therefore, when the recipient of the hidden information carrier peels off the peelable overlapping adhesive surface, the perforations are broken, and the peeled paper pieces are separated, maintaining the integrity as the hidden information carrier. There is an inconvenience that you cannot do it. It is an object of the present invention to provide a hidden information carrier sheet that solves this inconvenience.

[0004]

In order to achieve the above-mentioned object, the hidden information carrier sheet of the present invention has a linear or dot thin portion formed so as not to reach both ends of the folded portion. Two pieces of paper are connected to each other via a folding part, and an adhesive that can be peeled off after bonding is provided on at least one of the overlapping faces folded at the folding part, and the concealment concealment is provided on the overlapping face. A hidden information entry section is provided for entering information to be entered.

[0005]

When the information is output to the concealed information carrier sheet by a printer, the folded portion of the sheet is a linear or dot thin portion formed so as not to reach both end portions of the sheet, so that the paper Since the generation of powder is reduced and the folds are not projected, the print quality is degraded and the running property is improved. further,
Folding can be performed easily and surely with a folding machine, and it does not break like perforations during pressure bonding. Further, even when the paper piece is peeled off, there is no fear of being cut off from the folded portion because both ends are non-thin portions.

A sectional view taken along the line A, FIG. 4 is a schematic perspective view of a concealed postcard created in half, FIG. 5 is a plan view of the concealment information entry portion side where the concealed postcard of FIG. 4 is separated and developed, and FIG. 6 is a second embodiment. Fig. 7 is a schematic plan view of the surface side where two sheets of concealed postcards are arranged side by side, Figs. 7 to 9 show the third embodiment, and Fig. 7 is the surface after printing of the sheet of concealed postcards made of three pieces of paper. FIG. 8 is a schematic plan view of the side of FIG.
FIG. 9 is a schematic perspective view of a concealed postcard produced by folding the concealed postcard sheet of FIG. 7 in three lines.

First, a first embodiment will be described with reference to FIGS. As shown in FIGS. 1 to 3, a concealed postcard sheet 1 for making a concealed postcard includes a folded portion 2 including a dot-shaped thin portion 3 formed by a half slit that does not penetrate from one surface of the sheet to the other surface. With the border as a boundary, the lower paper piece 5 whose size on the side parallel to the folding portion 2 is slightly shorter than the upper paper piece 4 is connected. A destination information entry portion 6 is provided as a destination surface on the surface side of the top paper piece 4 which is the front surface side of the concealed postcard sheet 1 having the dot-shaped thin portion 3 formed by the half slit, and the bottom paper piece 5 is also provided. The sender information 7 is printed in advance on the front side of the. In addition, the overlapping surface of the upper paper piece 4 and the lower paper piece 5, which is the back surface side of the covert postcard sheet 1, is not usually bonded, but can be bonded by applying a predetermined pressure, and can be peeled off after bonding. Alternatively, while applying the printable pressure-sensitive adhesive 10 on the entire surface,
Adhesive strength reducing portions 11 are provided by halftone printing or the like along either one of the upper paper piece 4 or the lower paper piece 5 on two sides orthogonal to the folding portion 2. Also, under the title 9 of the "invoice",
A concealment information entry section 8 is provided in which item contents such as date, product name, quantity, unit price, amount of money are written. In this embodiment, the dot-shaped thin portion 3 formed by the half slit is
Since the sheet is formed from the side opposite to the concealment information writing section 8, the concealment information writing section 8 surface side does not cause unevenness on the sheet and does not impair the printability, so that the layout of the writing section is not restricted.

As the above-mentioned pressure-sensitive adhesive 10, a non-peeling adhesive base which is capable of printing and printing, and which is pressure-sensitive and cannot be re-peeled once adhered, has no affinity for this adhesive base. Those prepared by blending a fine particulate filler exhibiting properties are suitable. The adhesive base may be a conventional pressure-sensitive adhesive that has been conventionally used.In particular, natural rubber latex obtained by graft copolymerizing styrene and methyl methacrylate on natural rubber, It is suitable in terms of blocking resistance, heat resistance, abrasion resistance and the like.

On the other hand, the fine particulate filler has a small non-affinity with the adhesive base, for example, zinc oxide, titanium oxide, calcium carbonate, kaolin, activated clay, spherical alumina, wheat starch, silica, Glass powder, shirasu balloon or the like is used. These materials are
Although they may be used alone or in combination, a combination of silica and another appropriate filler is particularly preferable. Also,
When two or more kinds having different particle sizes are combined, the adhesive application surface can be easily formed in a concavo-convex shape, and thus the peeling performance is improved. Addition of silica can strengthen the coating film of the adhesive,
Due to its porosity, the adhesive easily adheres to the surface,
There is an advantage that the adhesive force and the peeling force can be easily adjusted. Also,
Even when printing is performed by a non-impact printer system using a silicone oil at the time of fixing the toner, since the silica absorbs the silicone oil, the adhesive does not become stuck due to the silicone oil.

The peeling strength of the adhesive surface of the pressure-sensitive adhesive 10 is adjusted by the blending ratio of the above-mentioned fine particulate filler. Further, in addition to the adjustment by the blending ratio of the fine particulate filler, if the pressure-sensitive adhesive 10 is applied in halftone dots, the application thickness is adjusted, or the tint block printing is performed, the adjustment is performed.
Adjustment of the peel strength becomes easier. Specific examples of the pressure sensitive adhesive 10 include a natural rubber latex obtained by graft-copolymerizing 2 parts by weight of styrene and 10 parts by weight of methacrylic acid with respect to 100 parts by weight of natural rubber, and a terpene resin tackifier. It is preferable to add 5 parts by weight of silica gel having an average particle size of 5 μm to 20 parts by weight of silica gel.

Next, a method for producing the concealed postcard 12 shown in FIG. 4 from the concealed postcard sheet 1 configured as described above will be described. First, while transferring the concealed postcard sheet 1 in a predetermined direction, the destination information previously input to the computer and the destination person are notified by a not-shown double-sided printer device which is an output device of the computer. Concealment information regarding items such as date, product name, quantity, unit price, amount of money, etc., which are the notification contents of the “invoice”, is printed on the concealment information entry unit 8. (See FIGS. 4 and 5) At this time,
Even when the concealment information is printed across the folded portion 2, it is not on the half slit forming surface, so that the concealment information can be printed smoothly, reliably and neatly. It should be noted that a general single-sided printer device may be used to perform printing on each side by two printing operations.

Next, as shown in FIG. 4, a folding device (not shown) is used to fold the concealed postcard sheet 1 so that the overlapping surface of the upper paper piece 4 and the lower paper piece 5 are in contact with each other.
Then, the destination information and the sender information 7 are displayed by folding in half and the concealment information is concealed to make it invisible to the outside. This folding operation is extremely easy and reliable because it is folded on the opposite surface side so that the half slit 3 is exposed. Next, a concealment postcard 12 in which a predetermined pressure, which is an adhesion condition of the pressure-sensitive adhesive 10, is applied by a pressure bonding device (not shown) having a pair of upper and lower pressure bonding rollers, and the overlapping surfaces are bonded in a peelable manner. To do. Since the folded portion 2 has the dot-shaped thin portion 3 formed by the half slit so as not to reach the both ends, the folded portion 2 is formed during this pressure bonding.
Does not break.

The concealed postcard 12 (see FIG. 4) thus created can be posted in the same manner as a general postcard. On the other hand, when the recipient who receives the concealed postcard 12 grasps the upper paper piece 4 having a slightly wide width direction and relatively separates the lower paper piece 5, the adhesive force reducing portion 11 of the overlapping surfaces located at the upper and lower end portions. As shown in FIG. 5, the adhesive surface between the upper paper piece 4 and the lower paper piece 5 is reliably and easily peeled off, and the concealed “invoice” is the notice content, the product name, the quantity, unit price,
Concealment information regarding items such as the amount of money is exposed and becomes visible.

Next, a second embodiment of the present invention will be described.
As shown in FIG. 6, the concealed postcard sheet 21 for creating the concealed postcard 12 is one in which two concealed postcard sheets 1 of FIGS. 1 and 2 are arranged side by side with a virtual dividing line V as a boundary. Since the configuration and the manufacturing method are the same, the same reference numerals are given and detailed description thereof is omitted.

Next, a third embodiment of the present invention will be described with reference to FIGS. 7 and 9. As shown in FIGS. 7 and 8, a concealed postcard sheet 21 for creating a concealed postcard.
Is a folded portion 22, 23 composed of dot-shaped thin portions 24, 25.
With the half slit formed in
A half slit that is divided into a middle paper piece 27 and a lower paper piece 28 having a slightly shorter width direction, and a half slit that divides the upper paper piece 26 and the middle paper piece 27 is provided on the front surface side of the covert postcard sheet 21, while A half slit that divides the paper piece 27 and the lower paper piece 28 is provided on the back surface side of the concealed postcard sheet 21.

On the front surface side (the side shown in FIG. 7) of the top paper piece 26, a destination information writing section 29 is provided as a destination surface, and sender information 30 is printed in advance. Also,
Normally, the overlapping surfaces, which are the front surface side of the middle paper piece 27 and the lower paper piece 28, are not adhered but can be adhered by applying a predetermined pressure, and can be peeled off after the adhering and printing or printing is possible. A pressure-sensitive adhesive 31 having the same structure as that of the pressure-sensitive adhesive 10 is applied over the entire surface, and along either side of the middle paper piece 27 and the lower paper piece 28 that are in opposite contact with each other through the folded portion 23. The adhesive strength reducing portion 35 is provided by halftone printing or the like. Also, under the title 33 of the "invoice",
A concealment information entry section 34 for item contents such as date, product name, quantity, unit price, amount of money, etc. is provided in advance by printing.

As can be seen from FIG. 8, the superposing surfaces, which are the back surfaces of the upper paper piece 26 and the middle paper piece 27, are not normally bonded, but can be bonded when a predetermined pressure is applied, and it is difficult to peel them off after bonding. A pressure sensitive adhesive 32 is applied. Since this overlay surface is a surface on which hidden information is not printed and does not need to be peeled off after bonding, a pressure sensitive adhesive 32 having an adhesive force which is difficult to peel is applied.
Instead, the pressure-sensitive adhesive 10 of the first embodiment or the pressure-sensitive adhesive that can be peeled off after adhesion similar to the pressure-sensitive adhesive 31 described above may be applied. When a peelable pressure-sensitive adhesive is applied after this adhesion, it is possible to display concealment information also on this overlapping surface.

Next, a method for producing the concealed postcard 36 shown in FIG. 9 from the above-mentioned concealed postcard sheet 21 will be described. First, while transferring the concealed postcard sheet 21 in a predetermined direction, as shown in FIG. 7, the destination information previously input to the computer and the destination information by the printer device, which is an output device of the computer, is not shown. Predetermined destination information entry section 29 and hidden information already-entered section that should be filled in with concealment information relating to items such as date, product name, quantity, unit price, amount of money, etc., which are the notification contents of the "invoice" corresponding to the person. Print on 34. At this time, as in the first embodiment,
Even if the concealment information is printed across the folded portion 23, it is not on the half slit, so that the concealment information can be printed smoothly, reliably and neatly.

Then, as shown in FIG. 9, by a folding device (not shown), the superposing surface which is the back side of the upper paper piece 26 and the middle paper piece 27, and the front surface side of the middle paper piece 27 and the lower paper piece 28. The concealed postcard sheet 21 is folded from each of the folding portions 22 and 23 into a Z-shaped three-fold so that the overlapping surfaces are in contact with each other, and the destination information and the sender information 30 are displayed. Concealment information concerning items such as date, product name, quantity, unit price, amount of money, which is the notification content of the “invoice” is hidden so that it cannot be seen from the outside. This folding operation is extremely easy and reliable because it is folded on the opposite surface side so that the half slits of the folding portions 22 and 23 are exposed.

Next, a pressure bonding device (not shown) having a pair of upper and lower pressure bonding rollers is used to apply a predetermined pressure which is a bonding condition for the pressure sensitive adhesives 31 and 32, and the folded overlapping surfaces are The back surface of the upper paper piece 26 and the inner paper piece 27 are difficult to peel off, and the front surface of the inner paper piece 27 and the lower paper piece 28 are peelable.
And During this crimping operation, the folded portions 22 and 23 have point-like thinned portions 24 and 25 formed by half slits so as not to reach both ends, and therefore, are not broken.

The concealed postcard 36 created in this way is
The postcard can be posted in the same manner as a general postcard, and the addressee who receives the concealed postcard 36 is the middle paper piece 2 whose width direction is slightly longer.
When the lower paper piece 28 is relatively separated by using 7 as a gripping piece, the adhesive surface between the inner paper piece 27 and the lower paper piece 28 is reliably and easily peeled from the adhesive force reducing portion 35 of the overlapping surfaces located at the upper and lower ends. However, the concealed information concerning items such as the date, product name, quantity, unit price, and amount of money, which are the concealed contents of the “invoice”, is exposed and becomes visible.

The present invention is not limited to the above-mentioned embodiment, and for example, the concealed postcard sheets 1 and 21.
May not be in a unit sheet state but may be in a continuous state at the beginning, and the two-fold state is not limited to a completely overlapping state and may be a partial overlap, and the three-fold state may be a Z-shaped folded state. Not limited to the stacking, the lower paper piece 28 and the upper paper piece 26 may be sequentially folded over the middle paper piece 27. When there are two pairs of overlapping surfaces in the tri-folded state, at least one pair of overlapping surfaces may be peelably bonded, and the other overlapping surfaces may be bonded with difficulty in peeling. The mating surfaces may both be peelable. In addition, a pressure-sensitive adhesive 1 for peelably adhering
0 and 31 are not limited to both of the overlapping surfaces, and may be provided on only one of them. Furthermore, pressure sensitive adhesives 10, 31
Alternatively, a heat-sensitive adhesive or a rewettable adhesive that can be peeled off after adhesion can be used. Furthermore, the folded portions 2, 22, and 23 formed by the dot-shaped thin portions 3, 24, and 25 may be formed by half slits, or may be formed by pressing, and the thin portions 3, 24, and 25 are linear. Of course, the fact that it may be formed does not change the purpose. In addition, as a means for facilitating peeling at the time of peeling, it is possible to cut out a corner to form a step or to form a perforation at the corner. At the peeling start part, "Please peel from here. The display such as "" may be printed. In addition, it goes without saying that the present invention can be applied to various cards having overlapping surfaces other than the concealed postcards 12 and 36.

[0023]

As is clear from the above description,
According to the present invention, the folding portion provided on the hidden information carrier sheet is formed on the opposite side to the hidden information writing surface by a linear or dotted thin portion by a half slit,
The generation of paper dust and the protrusion of the processed part are small, the printing quality and running stability in the printer are improved, and easy and reliable folding operation can be performed, and the crimping operation for bonding the overlapping surfaces. At times, a hidden information holder can be obtained in which the hidden information is surely hidden without breaking the folded portion. Furthermore, since both ends are non-thin parts even when the paper piece is peeled off, there is an effect that the paper piece is not separated from the folded portion.
