Description

  The present invention relates to a concealed postcard that enables confidentiality of the described contents, and more particularly to a concealed postcard suitable for an account transfer request form of a financial institution or the like.

A concealed postcard is a postcard that can be mailed with information concealed. As the configuration, for example, as shown in FIG. 4, a concealment tack paper 102 that can be separated through a perforation 101 on a postcard sheet 103 having an address writing field on the front surface 130 and a concealment information description field 105 on the back surface 131. Is attached. The concealing tack paper 102 is affixed with a concealment sheet 104 having one surface as a release adhesive application surface 140 on a release treatment surface 120X of the release paper 120 having a basis weight substantially equal to that of the postcard paper 103. Configured. In this type of concealment type postcard X ₁₀₀ , the concealment sheet 104 is completely separated from the release paper 120 of the concealment tack paper 102 and separated, and then the postcard form 103 is covered so as to cover the information description column 105. The information is hidden by pasting it back on. Then, the release paper portion 120 of the remaining concealing tack paper 102 is separated by the perforation 101, and only the postcard paper 103 is mailed and used.

  However, this type of concealment type postcard sometimes breaks the concealment sheet when the concealment sheet is peeled off, and sometimes breaks the postcard sheet when separating the remaining concealment sheet portion.

Therefore, in recent years, a postcard paper in which a postcard paper and a concealment paper coated with a peelable adhesive are joined in a foldable manner has been used. When this type of concealed postcard is folded after the release paper is peeled to expose the peelable adhesive surface, the information entry field is covered with the peelable adhesive surface of the cover paper and concealed. Therefore, since the postcard paper and the concealment paper are not separated, the postcard paper is prevented from being damaged.
Patent 2937732

  However, this type of concealed postcard is difficult to adjust the adhesive strength for the information entry field of the peelable adhesive to be used, and the adhesive remains in the information entry field at the time of re-peeling or the information entered in the information entry field is In some cases, the concealment information may become unreadable. Further, since the adhesive remains in the information entry column, when the sheets are read by a machine such as an OCR, the overlapped sheets are adhered to each other, causing trouble such as double feeding.

  Therefore, the main problem of the present invention is that the pressure-sensitive adhesive does not remain in the information entry column at the time of re-peeling, and the information written in the information entry column due to paper scraping at the time of re-peeling is not concealed. To provide a postcard.

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
The same size postcard paper and concealment paper are foldably joined together,
An information entry field is provided on the inner surface of the postcard paper for entering predetermined items.
An adhesive is applied to the entire inner surface of the concealment paper,

  In the concealment type postcard of the present invention, since the release agent is applied to the inner surface of the postcard paper provided with the concealment information entry field, the adhesive force between the inner surface of the postcard paper and the adhesive application surface does not become too strong, and at the time of re-peeling The adhesive remains in the information entry column, and the information entered in the information entry column is taken on the adhesive application surface, so that the entered information does not become unreadable.

  Further, when the release paper is foldably joined to the concealment paper and the adhesive application portion of the concealment paper is covered by the fold, the postcard can be obtained by folding one sheet into three. Paper, concealment paper, and release paper can be configured, which facilitates manufacture.

  Further, by partially varying the amount of the release agent applied to the inner surface of the postcard paper, a portion having a strong adhesive force and a portion having a low adhesive force are formed on the inner surface of the postcard paper. Accordingly, the release agent application amount distribution according to the design of the information entry column can be obtained.

  Further, by partially reducing or eliminating the coating amount of the release agent, it is possible to make a part that does not re-adhere once peeled off, and to make it clear that it has been intentionally opened.

  On the other hand, in the present invention, since the adhesive force between the postcard paper and the concealment paper is adjusted by a release agent applied to the inner surface of the postcard paper, a non-peelable adhesive that is inexpensive and easy to handle is used instead of a high peelable adhesive. It can be used, and in this way a cost-effective concealment postcard is obtained.

  On the other hand, the concealed postcard of the present invention is suitable for a reciprocal postcard in which the surface of the release paper is the outgoing address entry section and the opposite side of the information entry field of the postcard paper is the reply destination entry section.

Next, embodiments of the present invention will be described in detail below with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram according to a first embodiment of a concealed postcard according to the present invention. As shown in the drawing, the concealment type postcard X according to the present embodiment has a folding line 1 formed at the center of a sheet of rectangular paper, and one side of the folding line 1 is concealment paper 2, The other is postcard paper 3. Both sheets 2 and 3 can be easily folded by folding lines. The fold line 1 can be formed by a perforation or a crease. It is also possible to join the concealment paper and the postcard paper so that they can be folded together by joining the edges of square paper of the same size with an adhesive tape.

  As the base paper constituting the postcard paper X and the concealment paper 2, either recycled paper made from used paper or non-recycled paper made from virgin pulp can be used. Moreover, the papermaking method of the base paper is not particularly limited, and papermaking can be performed by a general papermaking technique of Western paper. After making the raw pulp into a slurry, it may be made by using a paper machine such as a long paper machine, a round paper machine, a twin wire type paper machine, or a multilayer paper machine.

  An adhesive 20 is applied to the inner surface of the concealment paper 2. Examples of the pressure-sensitive adhesive 20 include so-called peelable pressure-sensitive adhesives as disclosed in JP-A-2003-27026 and JP-A-2004-217838, and acrylic copolymer aqueous emulsions containing conventionally used alkyl acrylates. Although a peelable adhesive can be used, an emulsion-based strong pressure-sensitive adhesive other than the peelable pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a solvent-based pressure-sensitive adhesive, or the like can also be used. In particular, the concealed postcard X of the present invention can adjust the adhesive force according to the application amount and distribution of the release agent on the inner surface of the postcard paper 3 described later without adjusting the adhesive force of the adhesive itself. Therefore, it is desirable to use an inexpensive non-peeling adhesive.

The adhesive 20 can be applied by coating with various conventional coating machines such as an air knife coater, a blade coater, a rod metering coater, a curtain coater, and a roll coater. The application amount of the pressure-sensitive adhesive 20 is appropriately changed depending on the type of the pressure-sensitive adhesive 20 to be used, but is preferably 5 to 30 g / cm ² in consideration of the total weight of the entire postcard.

In the unused state, that is, the state before the information is concealed, the adhesive-applied surface 21 is covered with the release paper 4. The release paper 4 has a surface 41 facing the adhesive application surface 21 and a release agent such as silicon, a long-chain alkyl polymer, a polyolefin, an alkyd resin, and a fluorine compound applied to about 0.1 to 2.0 g / m ^2. General release paper that has been used can be used. In addition, paper that has been subjected to the same release processing as that performed on the information description surface of a postcard paper described later can also be used. In this case, it is possible to print on the back surface of the paper (adhesive contact surface, that is, the release processing surface) or to record information with a printer. It is preferable that the adhesive strength between the release paper 4 and the adhesive-coated surface 21 be 0.049 to 4.9 N / 50 mm in the measurement of the 180-degree peeling adhesive strength in 10 of JIS Z 0237. is there.

  On the other hand, on the inner surface 31 of the postcard paper 3 which is a folded surface with respect to the pressure-sensitive adhesive application surface 21, there is an information entry column 5 for describing concealment information such as predetermined information, particularly confidential information and information on financial institutions. Is provided. This information entry field 5 is provided by printing appropriate frame lines, characters, figures, etc. by offset printing, gravure printing or the like.

  A release agent 30 is applied to the inner surface 31 of the postcard paper 3 provided with the information entry field 5. The mold release agent 30 can be applied by coating with various conventional coating machines such as an air knife coater, blade coater, rod metering coater, curtain coater, roll coater, etc. In particular, pattern printing or solid printing. Printing coating by various printing such as offset printing, gravure printing, letterpress printing, and intaglio printing, in which it is easy to appropriately adjust the coating amount and distribution of the release agent, is suitable. The adhesive force of the postcard paper inner surface 31 with respect to the adhesive application surface 21 can be easily adjusted by the application amount and distribution of the release agent 30.

  On the other hand, on the outer surface 32 of the postcard paper 3, there is provided a mailing address entry field 33 for entering the mailing address and the like, and the mailing address is entered here.

  In the concealed postcard X of the present embodiment described above, after entering information in the information entry field 5, the release paper 4 covering the adhesive application surface 21 is released to expose the adhesive application surface 21, and the folding line 1 is folded so that the inner surface 31 of the postcard paper 3 and the adhesive application surface 21 face each other, the postcard paper 3 and the concealment paper 2 are detachably bonded, and information is provided on the inner surface 31 of the postcard paper. The information entered in column 5 is hidden.

  At this time, the adhesive force between the adhesive-coated surface 21 and the postcard paper inner surface 31 is 3 to 25 N / 25 mm as measured by the 180-degree peeling adhesive force at 10 of JIS Z 0237, preferably 6 -15 N / 25 mm is desirable. This can be easily adjusted by the type and application amount of the release agent 30 applied to the postcard paper inner surface 31.

  Thus, the information entered in the information entry field 5 can be mailed in a concealed state, and the recipient who receives the concealed postcard X reads the concealment information by peeling the concealment sheet 2 from the inner surface 31 of the postcard sheet. Is possible.
