Description

  The present invention relates to an information hiding card manufacturing sheet.

  As a postcard for concealing personal information displayed on a postcard when notifying personal information by postcard, an information concealment postcard using the card manufacturing sheet described in Patent Document 1 is known. .

  The card manufacturing sheet has the following configuration. It consists of a three-layer structure of a rectangular base sheet, a pressure-sensitive adhesive layer applied to the back surface of the base sheet, and a release sheet of the same type and the same size as the base sheet stacked on the pressure-sensitive adhesive layer. The vertical dimension (short side dimension) is almost the same as the vertical dimension of the standard postcard, and the horizontal dimension (long side dimension) is about three times the horizontal dimension of the standard postcard. One side of the base sheet is printable, and a pressure-sensitive adhesive layer is applied to the opposite side.

  The pressure-sensitive adhesive strength between the pressure-sensitive adhesive layer and the back surface of the base sheet is difficult to peel off, and the pressure-sensitive adhesive strength between the pressure-sensitive adhesive layer and the surface of the base sheet is set so as to be easily peelable and re-tackizable. .

  In addition, this card manufacturing sheet has perforations formed along the short side direction so that the entire area is divided into three equal parts of a standard postcard, and the base sheet is folded around the perforation. Can do.

  The area located in the center of the area of the back side of the release sheet divided into three equal parts by perforation is an address description area for displaying the mailing address when mailing the postcard. One of the areas adjacent to the area is an information display area for displaying information to be concealed. The other area is an information hiding area for hiding the information display area, and a ground pattern is printed to prevent the inside from being seen through the base sheet.

This card manufacturing sheet is used as follows.
First, information to be concealed such as address is printed in the address description area and personal information is printed in the information display area. Next, the release sheet is peeled to expose the pressure-sensitive adhesive layer, and the address writing area and the information display area are folded along a perforation so as to be folded in a mountain. Next, when folding along the perforation so that the adhesive surface on the back of the information concealment area and the information display area overlap, the information concealed in the information display area is concealed by the information concealment area. Can be mailed.

The person who received this information concealment postcard picks up the periphery of the information concealment area of this postcard, and peels the information concealment area that can be re-adhered from the information display area, so that personal information printed on the information display area, etc. Can read.
JP 2006-347130 A

  In such an information concealment card, the information concealment area is divided into a weak adhesive part that can be easily peeled off and a strong adhesive part that is difficult to peel off when affixed to the base sheet, and the boundary between the weak adhesive part and the strong adhesive part is provided. The cuttable part is formed by a perforation in which short slits are intermittently arranged in a straight line, and by cutting the perforation, only the weak adhesive part is peeled off from the information display area. It was possible to read personal information printed on the site.

  However, since the cuttable portion is composed of perforations formed linearly along the boundary line, the cut surface of the perforation is in a neatly aligned state without fluffing. On the other hand, the weak adhesive portion of the information hiding surface can be adhered to the postcard again after being peeled from the postcard. For this reason, if a third party other than the recipient opens the perforation, peels off the weak adhesive portion, steals the written information, and pastes it again, there is a problem that the trace of opening is difficult to remain.

  The present invention has been completed on the basis of the above circumstances, and once the information concealment area is peeled off, the information concealment can be suppressed by keeping the trace of unsealing clearly. The purpose is to provide a card.

  As means for achieving the above object, the present invention comprises a base sheet that can be folded in two by a fold line, and a release sheet that is peelably laminated on an adhesive layer applied to the base sheet. The release sheet has an area (information display area) for displaying information to be concealed in one area bordered by the fold line, and the other area is peelable. The base sheet is folded in two by the fold line in a state where the other region is peeled and the pressure-sensitive adhesive layer is exposed, and one of the fold lines of the base sheet is interposed through the pressure-sensitive adhesive layer. An area (information hiding area) can be superimposed on the information display area, and the adhesive layer of the information hiding area includes a strong adhesive portion corresponding to an outer area of the information display area and an inner side thereof. And the base sheet is formed with a severable part along a boundary between the strong adhesive part and the weak adhesive part, and the information concealment region is cut by cutting the severable part. The information display area of the release sheet can be exposed to the outside by peeling off the inner area of the sheet, and the severable part is inclined with respect to a boundary line between the strong adhesive part and the weak adhesive part. However, it is characterized by being constituted by a large number of slit groups arranged adjacent to each other.

  The present invention comprises a base sheet that can be folded in three by two fold lines, and a release sheet that is releasably laminated on an adhesive layer applied to the base sheet. When the three areas divided by the folding line of the book are the first area, the central area, and the second area, the second area is an area for displaying information to be concealed (information display area). The pressure-sensitive adhesive layer is formed by removing the release sheet in the first region in a state where the information display region is folded by one of the fold lines so that the release sheet side is inside and folded on the central region. The first area (information hiding area) of the base sheet can be overlaid on the information display area via the adhesive layer, and the adhesive layer of the information hiding area is outside the information display area A corresponding strong adhesive portion and a weak adhesive portion located inside the corresponding strong adhesive portion are formed, and a cuttable portion is formed on the base sheet along a boundary between the strong adhesive portion and the weak adhesive portion, and the cutting is possible. The information display area of the release sheet can be exposed to the outside by cutting the part and peeling the inner area of the information hiding area. The cuttable part includes the strong adhesive part and the weak adhesive part. It may be configured by a large number of slit groups arranged adjacent to each other while being inclined with respect to the boundary line of the portion.

  In this invention, you may form the said weak adhesion part by printing the surface treating agent which reduces adhesiveness on the surface of the adhesive which comprises the said strong adhesion part.

  For example, a postcard is produced using the card production sheet of the present invention as follows. First, assuming that the base sheet has an area divided into, for example, a postcard size by a fold line, the mailing address is printed on the central area of the divided base sheet on the side opposite to the release sheet, Information to be concealed for notifying the recipient is printed in another adjacent area. And after peeling off the release sheet on the back surface to expose the adhesive layer, the adhesive layer side is inside the address description area where the address is printed and the information display area where the information to be concealed is described Fold them together and paste them together. As a result, the address description area is located on one side and the information display area is located on the back side.

  Next, if the information concealment area, which is the remaining one area, is valley-folded with a fold line so that the adhesive layer side is inside and pasted to the information display area, the information display area is covered by the information concealment area It becomes a postcard. Of the pressure-sensitive adhesive layer in the information hiding area, the portion corresponding to the outer area of the information display area is a strong adhesion portion that is difficult to peel off, and therefore the outer peripheral edge portions of the information hiding area and the information display area are hardly peeled off. Therefore, if this postcard is posted and mailed, the information display area is mailed to the destination while being covered with the information hiding area.

  A recipient who has received this postcard can peel off the weak adhesive portion other than the outer peripheral edge along the severable portion of the information hiding area and see the information printed inside.

  In the present invention, the slit group constituting the severable part is arranged with an inclination with respect to the boundary line between the weak adhesive part and the strong adhesive part. A part of the base sheet is lifted from the information display area and is irregularly cut off.

  Therefore, even if the weak adhesive part that has been peeled off is re-applied to the original position, the slits are irregularly cut off and raised in the cuttable part surrounding the weak adhesive part. It is not possible to return to the state of the above, leaving a trace of opening. For this reason, unauthorized opening of a third party other than the recipient can be suppressed.

  Moreover, the weak adhesive part can be formed by printing the surface treating agent which reduces adhesiveness on the surface of the adhesive which comprises a strong adhesive part. If it does in this way, since it is not necessary to combine two types of adhesives, both material cost and manufacturing cost can be held down inexpensively.

<First Embodiment>
Hereinafter, a first embodiment in which the present invention is applied to a sheet for creating an information concealment postcard (hereinafter referred to as a postcard creation sheet 1) will be described with reference to FIGS. The postcard making sheet 1 of this embodiment is exemplified as one used when making an account transfer guidance postcard sent from an insurance company to a customer (recipient), for example.

  As shown in FIG. 2, this postcard making sheet 1 is stacked on a rectangular base sheet 2, an adhesive layer 3 that is applied to the back surface of the base sheet 2 so as not to be peeled off, and the adhesive layer 3. The base sheet 2 and the release sheet 4 of the same type and size have a three-layer structure. The vertical dimension (short side dimension) of the base sheet 2 is substantially the same as the vertical dimension of the standard postcard, and the horizontal dimension (long side dimension) is twice the horizontal dimension of the standard postcard (FIG. 1). .

  The base sheet 2 is made of paper, for example, and has a thickness of about 60 μm, for example, and the surface can be printed by a printer or the like.

  Further, as shown in FIG. 1, the base sheet 2 is formed with a single perforation 11 so that the entire region is equally divided into the size of a standard postcard along the short side direction. The perforation 11 is formed in a state where the release sheet 4 is overlapped on the base sheet 2 and is formed so as to penetrate both sheets. The base sheet 2 may be folded around the perforation 11. it can.

  Of the two areas of the same type and size divided by the perforation 11, the area located on the right side of FIG. 1 is an address description area 1A for describing the mailing address of this account transfer guidance postcard. In this address description area 1A, characters of “postcard”, stamp sticker frame and “confidential” are printed in advance, and other portions are blank until the user prints the address and the like.

  An area adjacent to the address description area 1A is an information hiding area 1B. Here, a ground pattern for preventing the inside of the base sheet 2 from being seen through is printed in advance (the ground pattern is not shown).

  In the adhesive layer 3 on the back side of the information hiding area 1B, a releasable ink 31 is printed in a rectangular area excluding a frame-shaped area having a width of about 5 mm inside the outer peripheral edge (only in FIG. 2). (Illustrated). The releasable ink 31 is prepared, for example, by mixing a release varnish and a black ink, and is printed by, for example, a relief printing method. When the releasable ink 31 is attached, the adhesive property of the pressure-sensitive adhesive is reduced. Therefore, the area of the pressure-sensitive adhesive layer 3 on which the releasable ink 31 is printed is more sticky than the area on the outer peripheral side that is not printed. Is low.

  Therefore, in the present embodiment, the rectangular area on which the releasable ink 31 is printed is referred to as a weakly adhesive part 3A, and the surrounding area on which the releasable ink 31 is not printed is referred to as a strong adhesive part 3B (see FIG. 5).

  The strong adhesive portion 3B (original adhesive layer 3) has an adhesive force that is difficult to peel off once attached to the base sheet 2, and the weak adhesive portion 3A is easily attached even once applied to the base sheet 2. It is set to have a peelable adhesive force. The adhesiveness of the weak adhesive part 3A is determined by the adhesion ratio of the releasable ink 31 in the weak adhesive part 3A (such as a halftone dot density when the ink adhering part is constituted by a halftone dot or a pattern) or the releasable ink 31. Can be adjusted by the concentration of the release varnish or the like in the preparation.

  As described above, since the weak adhesive portion 3A is a rectangular region, the boundary line with the strong adhesive portion 3B has a rectangular frame shape. As shown in FIG. 1, rounded L-shaped slits 21 are formed at two positions above and below the left corner along the boundary line in the information hiding area 1 </ b> B. Further, in a portion corresponding to the boundary line other than the one side on the right side extending above and below the boundary line, a large number of waveform slits 22 group inclined with respect to the boundary line are formed along the boundary line, Each corrugated slit 22 corresponding to the boundary line in the left-right direction extends from the L-shaped slit 21 to be perpendicular to the perforation 11.

  Each corrugated slit 22 is a triangular wave shape in which a V-shape and an inverted V-shape are continuous with one side in common as shown in the enlarged portion of FIG. The distance t is about 1 mm.

  As shown in FIG. 3, the release sheet 4 located on the back side of the base sheet 2 is separated by about 5 mm on the right side along the perforation 11 that separates the address description area 1A and the information hiding area 1B. A slit 12 is provided at the position. Of the two regions of the release sheet 4 divided by the perforation 11, a slit 13 on a rectangular loop is formed on the left side region along the outer periphery, and along the slit 13, the release sheet 4 Only the outer peripheral edge can be peeled, and the remaining area inside the release sheet 4 is a delivery information recording area 1C for printing information (delivery information) for notifying the recipient, and the user delivers Until information is printed, it is blank.

  The postcard-producing sheet 1 of the present embodiment has the above configuration, and a method for using the same will now be described.

  When the postcard making sheet 1 is used, the recipient's address is printed in the address description area 1A, and the delivery information to be concealed and notified to the recipient is printed in the delivery information recording area 1C.

  After printing, the release sheet 4 on the right side is peeled off from the slit 12 to expose the pressure-sensitive adhesive layer 3. Next, along the slit 13 on the loop of the left release sheet 4, only the outer peripheral edge is peeled off to expose the adhesive layer 3 (strongly adhesive part 3B) (FIGS. 4 and 5). As a result, the outer peripheral edge of the distribution information recording area 1C is surrounded by the strong adhesive portion 3B. Next, when the valley is folded around the perforation 11 so that the pressure-sensitive adhesive layer 3 is on the inside, and the information concealment area 1B is overlaid and pasted on the distribution information recording area 1C, one regular sheet as shown in FIG. A postcard of size is completed.

  If the postcard created as described above is posted and mailed, the outer peripheral edge of the back surface of the information hiding area 1B becomes a strong adhesive part 3B, and the outer peripheral edge of the distribution information recording area 1C is also a strong adhesive part 3B. Therefore, the information concealment area 1B and the distribution information recording area 1C are adhered to each other at the outer peripheral edge with difficulty in peeling (FIG. 7), and the information concealment area 1B does not peel off during mailing.

  Further, since the weak adhesive portion 3A on the back surface of the information hiding area 1B and the distribution information recording area 1C are bonded together, the inner area of the information hiding area 1B is peelable and adhered.

  The recipient who has received the postcard created by the postcard-preparing sheet 1 as described above follows the instructions printed on the surface of the base sheet 2 "Slowly peel away from here and look inside." The portion of the L-shaped slit 21 is peeled off, pinched here and pulled up.

  Then, first, the portion between the L-shaped slit 21 and the corrugated slit 22 adjacent to the base sheet 2 in the information hiding region 1B is cut off, and the end of the L-shaped slit 21 and the corrugated slit 22 are connected. In addition, the portion between the corrugated slit 22 and the next corrugated slit 22 is cut off, and the cut-out portion is widened.

  Therefore, if the L-shaped slit 21 is pinched and further pulled, the adjacent corrugated slits 22 are cut off one after another, and eventually the weak adhesive portion 3A and the strong adhesive portion along the rectangular boundary portion. As shown in FIG. 8, the information entered in the distribution information recording area 1 </ b> C can be read by opening the weak adhesive portion 3 </ b> A to the right as shown in FIG. 8.

  In the present embodiment, when the area corresponding to the weak adhesive part 3A in the information hiding area 1B is opened, a large number of slits constituting the severable part are formed on the boundary line between the weak adhesive part 3A and the strong adhesive part 3B. As shown in FIG. 9, a part of the base sheet 2 between each slit is lifted off from the postcard and irregularly cut off as shown in FIG.

  Therefore, even if we try to re-attach the weak adhesive part 3A once peeled off to the original position, not only the portions between the many slits are irregularly cut off, but also floats up in an irregular state. It is not possible to return to, and the trace of opening remains. Thereby, unauthorized opening of a third party other than the recipient can be suppressed.

Second Embodiment
10 to 19 show a second embodiment of the present invention. The same components as those in the first embodiment will be denoted by the same reference numerals, and redundant description will be omitted, and only different points will be described.

  In the postcard making sheet 20 of the second embodiment, the base sheet 2, the pressure-sensitive adhesive layer 3 and the release sheet 4 have the same configuration as that of the first embodiment (FIG. 11), but the lateral dimension of the base sheet 2 is a regular postcard. As shown in FIG. 10, the base sheet 2 has two perforations 14 so as to divide the entire region into three regular postcard sizes along the short side direction. , 15 are formed. The perforations 14 and 15 are formed through the base sheet 2 and the release sheet 4, and the base sheet 2 can be folded around the perforations 14 and 15.

  In FIG. 10, among the three regions of the same size and the same size divided by the perforations 14 and 15, the region located in the center is an address description region 20A for describing the mailing address of this concealed postcard. In this address description area 20A, as in the first embodiment, the letters “postcard”, stamp stamp frame and “confidential” are printed in advance, and other parts are blank until the user prints them. is there.

  An area adjacent to the right side of the address description area 20A is a distribution information recording area 20C for printing information (distribution information) for notifying the recipient, and is blank until the user prints the distribution information.

  The area adjacent to the left side of the address description area 20A is an information concealment area 20B, which is pre-printed with a ground pattern for preventing the inside from being seen through the base sheet 2 as in the first embodiment. (The ground pattern is not shown), the configuration of the adhesive layer and the slit group on the back surface is the same as that of the first embodiment.

  In FIG. 12, the release sheet 4 on the back side of the base sheet 2 can be divided into three sheets by two slits 16 and 17 along the perforations 14 and 15, and the base sheet 2 is attached to the release sheet 4 in the center. A copy-forgery-inhibited pattern for preventing the watermark from seeing the distribution information recording area 20C is printed.

  The post-preparation sheet 20 of the present embodiment has the above-described configuration, and a method for using the same will now be described.

  In order to use this postcard preparation sheet 20, first, the address information and the distribution information to be concealed are printed in the address description area 20A and the distribution information recording area 20C.

  In the present embodiment, unlike the first embodiment, the address description area 20A and the distribution information recording area 20C printed by the user are concentrated on one side. For this reason, for example, when printing with a printing machine, it is only necessary to print on one side, and workability is good.

  Next, the release sheet 4 on the left side of the slit 16 and the release sheet 4 on the right side of the slit 17 are peeled off to expose the adhesive layer 3 (FIGS. 13 and 14).

  Note that the portion where the background pattern is printed on the release sheet 4 between the slit 16 and the slit 17 is left without being removed.

  Then, the back surface of the distribution information recording area 20C and the copy-forgery-inhibited pattern printing portion of the release sheet 4 are bonded so as to be folded at the perforation 14 (FIG. 15).

  Next, when the valleys are folded around the perforation 15 so that the pressure-sensitive adhesive layer 3 is on the inside, the back surface of the information concealment area 20B is overlaid on the distribution information recording area 20C and bonded together, as shown in FIG. It becomes a postcard of a sheet.

  If the postcard created as described above is posted and mailed, the outer peripheral edge of the back surface of the information concealment area 20B becomes the strong adhesion part 3B, so the information concealment area 20B and the distribution information recording area 20C are outside. The information concealment region 20B is not peeled off during mailing or the like due to sticking to the peripheral edge with difficulty of peeling.

  Further, since the weak adhesive portion 3A on the back surface of the information concealment area 20B and the distribution information recording area 20C are bonded together, the inner area of the information concealment area 20B is peelable and adhered. When this postcard is mailed and the recipient opens it, the same is done as in the first embodiment (FIG. 19).

  In the present embodiment, a background pattern is printed in an area overlapping the back surface of the distribution information recording area 20C. For this reason, in the postcard state, the information entered in the distribution information recording area 20C cannot be seen through from the address description area 20A side. For this reason, security is higher.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) In each of the above embodiments, the postcard preparation sheet used for the account transfer guidance has been described. However, the application is not limited thereto, and information that is sent and handed over while keeping the information confidential. It can be widely used for concealment cards.

  (2) In each of the embodiments described above, slits that are inclined with respect to the boundary line form a continuous waveform by a unit line with respect to the slit group formed at the boundary line between the weak adhesive portion and the strong adhesive portion. However, it is not necessary that all the inclined slits form a waveform. For example, a portion formed only by an inclined slit may be included. Further, the waveform is not limited to a triangular waveform, and may be a sine waveform or a rectangular waveform.

  (3) In the first embodiment, the outer peripheral edge of the back side of the information hiding area is a strong adhesive part, and the outer peripheral edge of the information display area is also a strong adhesive part. The adhesive portion may be only on the back surface of the information hiding area.

  (4) In each of the above embodiments, in order to form the weak adhesive portion 3A, the non-adhesive release ink 31 is printed on the adhesive uniformly formed on the back surface of the base sheet 2. However, the present invention is not limited to this, and the adhesiveness may be lowered by partially subjecting the surface of the adhesive to chemical / physical treatment (for example, application of a release agent, heat treatment, electromagnetic wave irradiation, etc.). Alternatively, the adhesive is solid-printed on the strong adhesive portion of the back surface of the base sheet 2 and the adhesive is printed in a rough stripe or halftone dot on the weak adhesive portion to reduce the adhesion amount of the adhesive. Thus, the adhesiveness of the entire region may be reduced. Of course, two types of adhesives having different adhesiveness may be printed separately in the weak adhesive portion and the strong adhesive portion.

  (5) In the second embodiment, an information hiding postcard is obtained by dividing a rectangular sheet main body into three horizontally aligned regions along two fold lines formed along the short side direction, and sequentially folding the sheet body. For example, in a substantially L-shaped sheet body, the adjacent horizontal side is the information concealment area and the adjacent lower side is the distribution information recording area, with the background pattern printed on the release sheet as the center. A fold line may be formed at the boundary of each region. In this case, the information concealment postcard can be produced by folding the distribution information recording area upward and superimposing it on the area on which the copy-forgery-inhibited pattern is printed, and then folding the information concealment area laterally.
