Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a postcard, more specifically, a postcard used for the purpose of concealing information such as correspondence, especially an automatic printing machine such as a computer printer or a laser printer. It relates to postcards printed and used in.

(Prior Art) Conventionally, postcards used for the purpose of hiding information as described above include, for example, Japanese Utility Model Publication No. 52-90129 and Japanese Utility Model Publication No. 54-10224.
There are various postcards such as No. 2 and Jitsukai Sho 60-91462.

That is, these postcards are used so as to conceal the matters to be written on the inner surface side by being formed so as to be folded in two and by adhering the sheet pieces to be folded in two.

(Problems to be solved by the invention) However, in the postcard as described above, since the adhesive for adhering the sheet pieces is provided only on the peripheral portion of the sheet pieces, the adhesive is not provided. There is a problem that a gap may occur in a portion, and the adhesion between both sheet pieces cannot be maintained.

Further, since such a postcard adhesive is mainly a sticky adhesive, there is a problem such as stickiness in the hand even during its handling.

Furthermore, providing the adhesive only on the peripheral portion in this way is not always good in workability.

However, the conventional postcards as described above are mainly devised for general individuals, and therefore workability is not a big problem, but when, for example, a bank, a securities company, or another company mails a large amount of mail, When it is applied to a postcard in which a printer or the like is used to continuously print and then cut it, the work efficiency is significantly reduced.

Therefore, in order to solve all of the above problems, an adhesive is applied to the entire inner surface of the sheet piece as in JP-A-64-36493, JP-A-57-147069 and JP-A-62-3770. Some postcards are provided, but in the first place, the inner surface of the sheet piece is the surface on which information is displayed by writing, printing, etc., and if an adhesive is provided on the entire surface, it is difficult to display by writing, printing, etc. In addition, even if it is possible to display, the characters displayed after the separation between the sheet pieces may be transferred from one sheet piece to the other sheet piece side.

The present invention has been made in order to solve all of the above problems, and maintains the adhesion between the sheet pieces that make up a postcard, and enables automatic mass production in printers of various OA equipment. An object of the present invention is to provide a postcard that is capable of transferring characters and the like even after peeling between the sheet pieces.

(Means for Solving the Problems) The present invention has been made to solve such problems, and means for solving the problems include at least two sheets of the postcard body 1 which can be mutually superposed. In a postcard in which a heat-adhesive adhesive 4 is provided on substantially the entire inner surface of the sheet pieces 1a, 1b that are composed of the sheet pieces 1a, 1b and are polymerized with each other, adhesion between the sheet pieces 1a, 1b The agent 4 is an adhesive which contains an acrylic copolymer as a main component and to which a release agent such as wax is added.

(Operation) When the postcard having the above-mentioned configuration is used, first, necessary information is displayed on the inner surface of the sheet piece by printing or the like. In this case, the adhesive 4 is provided on the inner surface side of the sheet piece, but since the adhesive 4 can display characters and the like, the presence of the adhesive 4 hinders the printing of characters and the like. It will not be done.

Next, after displaying the necessary information as described above, the sheet piece is folded and polymerized, and the polymerized sheet piece is heated and pressure-bonded. The pieces will be immediately bonded.

By post-bonding the sheet pieces in this manner, a postcard is formed and can be mailed.

Next, the recipient who receives the postcard as described above can read the information displayed on the inner surface side of the sheet piece by separating the sheet pieces of the postcard. In this case, since the heat-adhesive adhesive 4 contains the release agent such as wax as described above, the sheet pieces can be easily peeled off, and the displayed information can be displayed on one side. There is no transfer from one sheet to the other sheet.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a postcard as an example, (a) is a front view, (b) is a rear view, (c) is an enlarged cross-sectional view taken along the line AA of (b), and (d) is (c). It is a B section expanded sectional view.

In FIG. 1, reference numeral 1 denotes a paper postcard body composed of one sheet, which is constituted by connecting two sheet pieces 1a and 1b of the same size in series.

A destination / address display unit 2 is provided on the outer surface side of one of the sheet pieces 1a to display the destination / address by printing with a laser printer, and FIG. 2 is shown on the inner surface side of both sheet pieces 1a, 1b. As shown in (a), the information display portions 3a and 3b are provided, and the inner surface side of the sheet pieces 1a and 1b is heat-adhesive and can be peeled after the adhesion, and the upper surface is printed, Characters can be displayed by copying, etc., and an adhesive that does not transfer the characters to the facing sheet side after peeling off the sheet pieces 1a, 1b, that is, an acrylic copolymer as a main component, An adhesive 4 containing a small amount of wax is provided on the entire surface.

The laser printer prints characters as necessary information on the upper surface of the adhesive 4.

Further, the two sheet pieces 1a and 1b are the same as the information display portions 3a and 3b.
Is bent through the bent portion 5 so that
Moreover, the entire surface between the sheet pieces 1a and 1b is heat-bonded in a peelable manner via the heat-bonding adhesives 4,4.

Reference numeral 6 denotes an advertisement / advertisement section provided on the outer surface side of the sheet piece 1b.

In addition, the postcard main body 1 is, as shown in FIG.
An opaque sheet 8 made of an aluminum vapor-deposited film is interposed between the sheets of paper 7, 7 to form three layers.

In the postcard 9 of this embodiment, as described above, the sheet pieces 1a and 1b facing each other so as to conceal the information display portions 3a and 3b are polymer-bonded to the substantially entire surfaces of both sides via the heat-adhesive adhesive 4. Since it is configured, there is no gap between the sheet pieces 1a and 1b, and the adhesion between the sheet pieces 1a and 1b is maintained.

Further, the information printed on the inner surface side of the sheet pieces 1a and 1b is completely hidden by the sheet pieces 1a and 1b. Therefore, the contents of the message are kept completely confidential during mailing.

In particular, since the postcard body 1 is composed of three layers by interposing the opaque sheet 8 made of an aluminum vapor deposition film between the two sheets of paper 7 and 7 as described above, it is displayed in the information display portions 3a and 3b. The opaque sheet 8 prevents the outside information from being seen through, and thus the confidentiality retaining effect becomes very good.

On the other hand, the recipient who has received the postcard 9 can read the information displayed on the information display portions 3a, 3b by separating the sheet pieces 1a, 1b from each other as shown in FIG. Becomes

In this case, since the heat-adhesive adhesive 4 contains a small amount of wax, the sheet pieces 1a and 1b can be easily separated.

Moreover, the displayed information is not transferred from one sheet piece 1a to the other sheet piece 1b side, and is not transferred from the other sheet piece 1b to the one sheet piece 1a side.

Incidentally, in the above embodiment, the entire inner surface side of the sheet pieces 1a, 1b are adhered, but it is not always necessary to adhere the entire surface, for example, a part of the non-adhesive portion is formed, A non-peelable adhesive may be provided on the part in addition to the above-mentioned heat-adhesive adhesive.

In short, it suffices that the substantially entire surface between the sheet pieces 1a and 1b be bonded. That is, the term "substantially the entire surface is adhered" as used in the present invention means that the entire surface is adhered except for the case where the entire surface is adhered and a part of the non-adhesive surface on the tip side as in the above embodiment is left. It is meant to include a wide range of cases.

The postcard body 1 is not limited to the two-fold type as in the above-described embodiment, but may be, for example, a three-fold type, and the folding method does not matter.

Further, in this embodiment, a wax as a release agent is mixed with an acrylic copolymer as a main component of an adhesive,
For example, it is also possible to previously encapsulate only the release agent in the microcapsule and mix the release agent-encapsulated microcapsule with the main component of the adhesive. In this case, the main component of the adhesive and the release agent are not directly mixed, and the release agent in the microcapsules gradually flows out from the wall material of the microcapsules and gradually enters the main component of the adhesive. Since it is mixed in the adhesive, there is an advantage that the peeling effect of the adhesive can be maintained for a long time, and therefore the adhesive does not change with time such as deterioration in peelability.

Further, in the above-mentioned embodiment, since the postcard main body 1 has a three-layer structure in which the opaque sheet 8 made of an aluminum vapor deposition film is interposed, it is preferable that the information in the information display portions 3a and 3b can be prevented from being seen through from the outside. Although the effect was obtained, the structure of the postcard main body 1 is not limited to the embodiment and can be changed arbitrarily, and such a see-through preventing means is not an essential condition for the present invention.

Further, in the above embodiment, the case where the information is printed by the laser printer has been described, but the invention is not limited to the laser printer, it is also possible to print by a dot printer, and further, copying other than such printing, writing, etc. It may be displayed by means, and the means for displaying information does not matter.

In the present invention, the main purpose of the present invention is to use a paper material as the postcard body 1, such as the one in which the aluminum vapor deposition film is interposed between the paper sheets as in the above embodiment, or the one made of only paper. However, it does not prevent the use of materials other than paper.

Further, the means for opening the postcard main body 1 may be any means such as cutting with scissors or dividing perforations.

Further, although the present invention is mainly intended for commercial postcards that are automatically and continuously produced by a printer or the like,
It is not necessarily limited to business use, and postcards used for general household use also belong to the scope of the present invention.

(Effects of the Invention) (a) As described above, according to the present invention, at least two or more postcard main bodies are formed in a superposed state so that the surface on which the information to be concealed is displayed is the inner surface side, and the superposition thereof. Since almost the entire surface between the sheet pieces to be peeled off is peelably bonded via the heat-adhesive resin, there is almost no gap between the sheet pieces that make up the postcard, and the adhesion between the sheet pieces is ensured. The effect is that the adhesiveness can be significantly improved as compared with the conventional postcard as described above.

(B) More importantly, since the heat-adhesive adhesive can display characters and the like, the presence of the adhesive does not hinder the printing or copying of the characters. Since the agent is peelable and has the property of preventing the transfer of characters between the sheet pieces, the sheet pieces can be easily peeled off, and the displayed information can be transferred from one sheet piece to the other. It does not transfer to one side of the sheet.

(C) Therefore, even though substantially the entire surface between the sheet pieces is adhered, characters or the like can be displayed on the upper surface of the adhesive, and the characters or the like are not transferred.
We obtained the effect that postcards can be provided as an epoch-making communication medium that has the rather contradictory effects as in (b).
