Description

Description: BACKGROUND OF THE INVENTION (Industrial application field) The present invention relates to a communication information stack (hereinafter, referred to as an information communication body) which replaces a postcard, a sealed letter, a round-trip postcard, and the like.
For more details, it is apparently a single leaf postcard, or a reciprocating postcard, but has a plurality of information display surfaces inside,
The present invention relates to an information communication body in which more information can be provided and the displayed information can be concealed and mailed.

(Prior art) In general, an "information communication body" is formed by dividing a sheet of paper into a predetermined number of information display surfaces, folding the same, and peeling and bonding the combined information display surfaces together (hereinafter referred to as pseudo-adhesion). The information is concealed and can be mailed. The information includes information that does not require confidentiality (eg, advertising texts and explanations addressed to an unspecified majority, other lines, frames, patterns, figures, and the like) and information that is individual and requires confidentiality.

Since this type of information communication body is often used for direct mail, it is produced in large quantities. The inventor of the present invention has invented a communication sheet and a method of manufacturing the same as a method for mass production (Japanese Patent Application No. 63-205263).

In this method, one layer of a transparent resin film for pseudo-bonding is permanently bonded to the pseudo-bonding surface of the mount, and the mount is folded in two, the resin films are joined together, and then heat-pressed in the folded state. A single-leaf information communication body is formed by pseudo-bonding comrades.

(Problem to be Solved by the Invention) The communication sheet proposed in the future is suitable for mass-producing information communication bodies, but has the following problems. That is, since the film to be hung on the backing is a single layer, if the surfaces of the films are aligned and heated and pressed in this state, the same quality films are bonded together. However, films of the same quality melt and unify when heat or pressure is applied too much, making it difficult for the receiver to peel off.The adhesive surface between the film and the backing, which should have been permanently bonded with the force of forcibly peeling off, is forcibly applied. It may be peeled off, exposing the mount surface. After all,
Pseudo-adhesion will no longer be pseudo-adhesion. Also, if the permanent adhesive surface is forcibly peeled off, the mount surface becomes ugly,
Unable to read the information on the corner. After all, in the above-mentioned invention, it was necessary to control the temperature and pressure of the heat roller and the like so as not to excessively soften and melt the film surface, and to perform the pseudo bonding, so that experience and technology were required for production.

Therefore, in order to make it easy for even a novice to produce, the present inventor has further invented a "communication sheet and its material" (Japanese Patent Application No. 1-314036). This “sheet for communication and its material” is obtained by permanently bonding a transparent synthetic resin film having a relatively high softening and melting temperature to heat as a first layer on the backing surface, and having a lower softening and melting temperature on the first layer. A transparent synthetic resin film is pseudo-bonded as a second layer. As a result of this configuration, the opposing surfaces to be heat-pressed become the second layers having a softening / melting temperature lower than that of the first layer with respect to heat. Even if a force for opening the pseudo adhesive surface is applied, the permanent adhesive surface does not accidentally open.

The present invention is an information communication body formed based on the above “communication sheet and its material”. The information communication body according to the present invention replaces conventional postcards, round-trip postcards, and sealed letters. The distinction between a postcard and a sealed letter here is based on the difference in fee due to size and weight, not form.
The advantage of the present invention over conventional envelopes is that the postage is the same as the envelope fee, but the cost of the envelope and the labor cost of putting it in the envelope are not required.

(Means for Solving the Problems) In order to achieve the above object, a transparent synthetic resin film having a relatively high softening and melting temperature is permanently bonded as a first layer to the mount of the information communication body of the present invention. It is characterized in that a transparent synthetic resin film having a lower softening / melting temperature is pseudo-bonded as a second layer on one layer, and then folded or overlapped to fuse and integrate the mating faces.

(Action) Since the two-layer film-coated surfaces having relatively low softening and melting temperatures with respect to heat are bonded together under heat and pressure, they are melted and integrated unpeelably.

(Example) Regarding the relationship between the backing sheet 1, the sheet (A), and the information communication material (B).

FIG. 1 is a plan view of a sheet (A) as one unit. The illustrated paper (A) shows a case where four mounts 1, that is, four information communication body materials (B) are manufactured.
However, a desired number of sheets (for example, 25 sheets) can be obtained according to the size of the sheet (A). Printing of information
This is performed on the sheet (A). The mount 1 is cut from the sheet (A) by various methods such as cutting or punching with a Thomson blade. Since the cut backing 1 is not yet in the form of an information communication body, the information communication body material (B) is used for convenience.
Say This information communication body material (B) is finished into a predetermined information communication body as described later.

A transparent synthetic resin film 3 is permanently bonded as a first layer to the printed paper (A). Various methods are known as a method of permanent bonding. First, a pressure-sensitive adhesive is applied to the back surface of the synthetic resin film in advance, and the paper (A)
If there is a release paper on the application surface when sticking, remove the release paper and attach it. The second is the use of an adhesive that is not tacky at room temperature and pressure and does not require a release paper.
The back surface of the layer film 3 or the back surface of the layer film 3 and the surface of the paper (A) are applied, and are pressurized in a non-heated state to be permanently bonded to the paper (A). Third, a heat-sensitive adhesive is applied to the back surface of the first layer film 3 and is permanently bonded by thermocompression bonding. The first layer of the synthetic resin film 3 is made of a synthetic resin having a relatively high softening and melting temperature with respect to heat, for example, polyester, polypropylene,
It is formed by acetate or the like.

Next, a transparent pseudo-adhesive film 4 is laminated as a second layer on the first layer film 3 by a known method.
The film 4 of the second layer is made of a synthetic resin having a lower softening and melting temperature than the film 3 of the first layer, for example, polyethylene, ethylene-ethyl acrylate copolymer, a mixture of ethylene-vinyl acetate copolymer and polyethylene, and the like. It is formed.

In the above method, the first layer 3 is permanently bonded to the paper (A), and then the first layer 3 and the second layer 4 are pseudo-bonded. The layered film can be permanently adhered to the paper (A) by any of the methods described above. However, when a heat-sensitive adhesive is used as the permanent adhesive, it is necessary to cut off heat so that the pseudo-adhered second layer film 4 is not melted by heat compression. For example, in the case of a pair of heat rollers, a method in which heat is applied only to the heat roller on the first layer 3 side and no heat is applied to the second layer 4 side, or a method of applying a blocking sheet is used. is necessary. The cutting and punching steps are performed, for example, on a sheet (A) covered with a two-layer composite film.
Is folded along a folding line (2) of each mount (B) into a double door and passed through a heat roller to fuse and integrate the second layer film 4, and then cut or punched out in the final step to cut or cut the makeup. You may.

Example (1) Example (1) is a case in which the same mount is variously processed. FIG. 2A shows a two-layer film 3 hung on a mount 1,
4, a permanent adhesive layer 5, and a pseudo-adhesive layer 6 a, 6 b are shown in a laminated state (hereinafter, a two-layer film in which the first layer 3 and the second layer 4 are pseudo-adhered will be referred to as two layers for convenience). A composite film). From the paper (A) on which the two-layer composite film is hung, the mount 1 is cut out or punched out as described above, and the unitary mount 1 is bent in the direction of the arrow in the figure to join the second layer 4 together, and is heated by a heat roller. Thermocompression bonding. As a result, as shown in FIG. 2B, the second layers 4 are melt-integrated and permanently bonded so that they cannot be separated. The heat roller may be a heat press. Usually, the heat may be about 80 to 140 ° C. and the pressure may be about 4 to 7 kg. However, the heating temperature and the pressure are determined by external conditions such as the properties and amount of the composition of the film or the adhesive and the room temperature.

Reference numeral 7 denotes a discontinuous cut such as a perforation, which is provided for convenience when peeling the pseudo-adhesive surface.
Of course, continuous cuts such as slits can be provided. The location may be provided along the opening side end as shown in FIG. 2C, or may be provided at a part of the opening side end as shown in FIG. 2D. Instead of providing slits or perforations, one edge may be slightly displaced from the other and folded, and a step (not shown) may be provided therebetween.

Embodiment (2) Embodiment (2) is a case where two separate mounts are variously processed as shown in FIG. 3A. That is, two mounts
1a and 1b concealed surfaces (mainly information display surfaces that require confidentiality)
After the two-layer composite film is permanently adhered to each other, the mounts 1a and 1b are aligned so that each second layer 4 is on the inside, and the two layers are fused and integrated by heating and pressing (FIG. 3B). . Thus, the two mounts are integrated while the information on the concealing surface is concealed. If the size of the backing paper 1 is set to two postcards or two large sealed letters, the integrated laminate can be further folded. In this case, if the two-layer composite film bonded to the mount surface to be folded is fused and integrated with each other, the postcard body has more information display surfaces (Fig. 3D). If you use it simply by folding it without using it, it will be a reciprocating postcard with many built-in information display surfaces (Fig. 3C).

In any case, the appearance is the same as that of a conventional postcard or a round-trip postcard.

Embodiment (3) Embodiment (3) is a case in which three or more separate mounts are variously processed. FIG. 4 shows three typical mounts 1c, 1d and 1e.
Is shown. The two-layer composite film is adhered to one side of the concealing surface of the mounts 1c and 1e, and the two-layer composite film is adhered to both sides of the concealment side of the mount 1b, and the three layers of the mounts 1c, 1d, and 1e are combined with the second layer 4 together. Are laminated as follows. If the size of each mount 1 is set to two postcards or two large sealed letters, the integrated laminate can be further folded. In this case, as in the case of the embodiment (2), a two-layer composite film is adhered to the mounting surface to be folded, and the combined second layer 4 is permanently adhered to each other to form a multi-layered information display surface. If the composite film is simply folded without using a composite film, it becomes a three-layer reciprocating postcard.

Even if the two-layer films 3 and 4 are immediately hung on the paper (A), they are held in the form of a two-layer composite film, and are appropriately ordered.
Alternatively, it can be supplied to the user in that state, and the user can adhere to a sheet according to his or her own specifications to complete a desired information communication body.

In the embodiment (3), a case where three mounts are used as a typical example is shown. However, a desired number of mounts may be stacked in a number of four or more to form an information communication body having a multi-layer structure by the above method.

(Effect of the Invention) The facing surface (second layer) to be thermocompression-bonded is a homogenous film whose softening / melting temperature is relatively lower than that of the first layer due to heat, so that it is melt-integrated, so that the recipient has a concealing surface. Only one of the first and second pseudo-adhesive layers 6a and 6b is peeled off even if a force is applied to open the box. Therefore, since the concealing surface is opened in a state of being breached by the first layer film 3, the information surface is not stained or damaged.

It is suitable for mass production using inexperienced people, since there is no need to pay special attention to the adjustment of temperature and pressure during the thermocompression treatment.
