Abstract

PROBLEM TO BE SOLVED: To prevent impossibility of releasing first layers from one another due to blocking by forming a resin layer having relatively low softening melt temperature as a second layer on a first layer of a specific resin layer formed on a mounting sheet, superposing the second layers of the sheet formed with both the layers, and releasably integrating opposed surfaces. SOLUTION: A first layer 3 and a second layer 4 of a resin layer are formed on a surface of a mounting sheet 1. As the first layer, a resin layer solidified under predetermined conditions like thermosetting, ultraviolet curable or hot-melt overprint varnish or ink is used. As the second layer, resin having lower softening melt temperature than that of resin of the first layer such as polyethylene or ethylene-vinyl acetate copolymer is formed on the first layer for use. And, when the sheet 1 formed with the first, second layers 3, 4 is folded along a folding line 2, heated and pressurized, the resins of the layers 2 are melted and brought into close contact with one another, but a boundary of the first and second layers is not collapsed, and not subjected to anabolism.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication information stack (hereinafter referred to as an information communication body) which replaces postcards, reciprocating postcards, sealed letters, and the like. In detail, while apparently a single leaf postcard, or a reciprocating postcard, it has a plurality of information display surfaces inside, so that more information can be loaded, and the displayed information is hidden. It relates to an information communication body that can be mailed.

[0002]

2. Description of the Related Art In general, an "information communication body" is such that one mount is divided into a predetermined number of information display surfaces and folded, or separate mounts are opposed to each other so that the combined information display surfaces can be separated from each other. The information displayed by bonding (hereinafter, referred to as pseudo bonding) is concealed and can be mailed. Note that the information includes information that does not require confidentiality (eg, advertising phrases and descriptions addressed to an unspecified majority, other ruled lines, frames, patterns, figures, and the like) and information that is individual and requires confidentiality.

[0003] As a method of pseudo-adhesion of a mount, a pseudo-adhesive laminate in which films are releasably laminated is sandwiched between opposing display surfaces of the mount, or a film layer is formed on the opposing display surface of the mount. A method in which the film layers are opposed to each other and pseudo-adhesion is performed by heating and pressurizing may be considered.

[0004]

However, according to the former method of the pseudo-adhesion laminate, very different pseudo-adhesions (reliable peeling from the interface between the films) are achieved because different types of films having different physical properties are laminated on a plurality of layers. Can be obtained, but the cost of raw materials and processes is high, and complicated operations such as alignment with the mount surface during manufacturing are required.
In the latter method of forming a film layer, although the disadvantages caused by the raw materials, work steps, alignment, etc. of the former method are eliminated, the opposite mounting surface becomes a film layer of the same quality. When forming, a portion that is always melted and integrated occurs, and a problem of poor opening due to blocking occurs.

[0005]

In order to achieve the above object, a resin layer which solidifies under a certain condition is formed as a first layer on a mount of the information communication body of the present invention, and a softening and melting layer is formed on the first layer. A resin layer having a relatively low temperature is formed as a second layer, and the second layer of the mount on which the first and second layers are formed is overlapped with each other so that the opposing surfaces are peelably integrated.

[0006] The form of the backing sheet that is finally integrated is such that even if one backing sheet is folded and the opposing surfaces thereof are pseudo-adhered,
It is also possible to pseudo-adhere the opposing surfaces of the separate mounts. Furthermore, it is also conceivable to add a free mount to the information communication body integrated by pseudo-adhesion and use it as an information communication body such as a reciprocating postcard, in which case a plurality of reply postcards are further laminated by pseudo-adhesion The information communication body may be used.

As the first layer, a resin layer that solidifies under certain conditions is selected. For example, a thermosetting type, an ultraviolet curable type, or a hot melt type overprint varnish or ink can be used. Drying other than varnish and ink,
The resin is not limited as long as it has a high solidification speed. The higher the speed of drying and solidification, the higher the work efficiency, and therefore the cost can be reduced.

The second layer is made of polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ethylene-acrylic acid copolymer (EAA), polyamide, Resins made of polypropylene or polyester alone or a mixture thereof can be selected. If a hot-melt resin is selected for the first layer, a resin having a softening / melting temperature lower than that of the resin can be used.

When the resin layer side surfaces of the mount on which the first and second layers are formed are opposed to each other, the resin of the second layer of the same quality comes into close contact. In this state, when heated and pressed by a heat roller, a heat panel, or the like, the resins of the second layer are melted and the boundary surface disappears and is assimilated. However, the first layer and the second layer have different physical properties even in a heated and pressurized state, and the first layer has a higher softening / melting temperature than the second layer. After all, mount / first layer / second layer / second layer /
The second layer of the resin layer opposed in the first layer / mounting structure is assimilated into a structure of mounting / first layer / second layer / first layer / mount.

[0010] When the mounts on both outer sides of the information communication body thus formed are to be peeled and opened, they are peeled off from the interface between the first layer and the second layer having a low peel strength or the second layer.
It is separated from the middle of the layer or peeled and developed in the form of a mixture of both. However, since the thickness of the second layer is extremely thin (several microns), it can be recognized only by the naked eye as a smooth film surface, and the same applies to the feel.

[0011]

[Function] When the resin surfaces of the backing sheet are opposed to each other and are pseudo-bonded,
Since the first layers formed on the backing paper are not directly interposed but always pass through a second layer having different physical properties, the first layers are not melted and integrated. Therefore, if you try to peel and open the mount,
Peeling and development can be ensured from the interface between the first layer and the second layer or the middle of the second layer.

[0012]

FIG. 1A is a plan view of a sheet (S) as a unit on which printing is performed in offset printing or the like. The illustrated sheet (S) shows a case where four mounts 1, that is, four information communication material (X) are manufactured. However, a desired number of sheets (for example,
16 sheets are possible). Printing of information is performed on the sheet (S). The mount 1 is cut from the sheet (S) 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, it is referred to as an information communication body material (X) for convenience. This information communication body material (X) is finished into a predetermined information communication body as described later.

In addition to the cut printing such as the offset printing, it is possible to use a continuous long sheet of paper (S) such as a form printing as shown in FIG. 1B. In the present embodiment, the former example will be described. However, the latter printing method is basically the same except for the form of the sheet (S), and the work steps for finishing the information communication body and its configuration are basically exactly the same. .

A transparent resin layer is formed as a first layer on the printed paper (S). As a method for forming the resin layer, a known method can be employed. For example, various roll coater methods, air doctor coater, blade coater, rod coater, knife coater, squeeze coater, slot orifice coater, extrusion coating, cast coating, etc. can be adopted, and further, in each method, solvent, non-solvent, A solution coating method such as hot melt or emulsion can be adopted.

After the first layer has been applied to the backing paper, the process proceeds to the drying step. The drying method can be completed in a very short time by passing through a UV lamp if the first layer is an ultraviolet curable type and passing through an EB irradiating device if the first layer is an electron beam curable type. In the case of hot melt, a separate drying device is not required, and when the temperature falls below the softening and melting temperature, the material is solidified spontaneously, but a cooling device can be added. The second layer may be formed in a similar manner after the formation of the first layer.

There is no particular limitation on the step of finishing each information communication material (X) from the paper (S) into a single information communication body. For example, the first and second layers are formed on the paper (S). After the cutting and punching steps, the individual information and communication body material (X) may be finished with a heat roller or the like, or the paper (S) on which the first and second layers are formed may be folded and heated. After a plurality of information communication body materials (X) are pseudo-adhered to each other, they may be finished as a single item through a cutting or punching process.

(Embodiment 1) Embodiment (1) is a case in which a mount of the same body is variously processed. FIG. 2A shows a state of the first layer 3 and the second layer 4 of the resin layer formed on the surface of the mount 1 and the pseudo-adhesion portion 5 at the boundary surface between them.

From the paper (S) on which the first and second layers are formed, the information communication material (X) is cut or cut out as described above, and the unitary mount 1 is cut along the folding line 2 by an arrow in the figure. Then, the second layers 4 are overlapped with each other and heated and pressed by a heat roller. As a result, FIG.
As shown in (2), the second layers 4 are fused and integrated. The heat roller may be a press by a heater panel. Normal,
The heat may be 80-140 ° C and the pressure may be about 4-15kg,
The heating temperature and pressurizing pressure are determined by external conditions such as the properties and application amounts of the resins of the first and second layers, and room temperature.

(Embodiment 2) Embodiment (2) is a case where the same mount is processed by a plurality of folding lines. FIG. 3 shows a typical example of a three-fold (Z-fold) mount 1. After forming the first and second layers on the two-thirds concealing surface on the front left side of the mount 1 and the two-thirds concealing surface on the back right side (mainly an information display surface that requires confidentiality), the second layer 4 is located inside. In this manner, the sheet is bent along the folding lines 2 in the direction of the arrow in the figure and integrated by the method of the first embodiment.

In this embodiment, Z-folding of a three-fold backing sheet has been described. However, the form of the backing sheet 1 having a plurality of folding lines such as three-fold winding, four-fold double-folding, and the like, and the winding and jabber Although a combination of folding forms is conceivable, all of the first and second surfaces are opposed to each other as in the second embodiment.
By forming two layers, they are integrated. Further, it is not necessary that all the opposing surfaces can be peeled off by pseudo-adhesion. For example, the first and second layers are formed only on one of the front and back surfaces of the mount 1 in FIG. You may make it impossible to peel off with a double-sided adhesive film or the like. In short, the number of the fold lines 2 of the backing sheet 1 and the peeled or non-peeled surface may be appropriately determined according to the use and purpose of the information communication body.

(Embodiment 3) Embodiment (3) is a case where a separate mount is processed as shown in FIG. 4A. That is, after forming the first and second layers on the respective concealing surfaces of the two mounts 1a and 1b, the mounts 1a and 1b are arranged such that the second layers 4 are on the inside.
When b is overlapped, heated and pressed, the second layers 4 are fused and integrated (FIG. 4B). As a result, the information on the concealing surface is concealed and the two mounts are integrated by pseudo bonding.

The size of the backing sheet is two postcards or a
If it is set to the number of sheets, the integrated mount can be further folded. In this case, if the first and second layers are formed on the opposing surface of the mount to be folded, the postcard has more information display surfaces (FIG. 4D). It is a reciprocating postcard with a built-in surface. (FIG. 4C) In any case, the appearance is the same as that of a conventional postcard or a round-trip postcard.

Embodiment (4) Embodiment (4) is a case where three or more separate mounts are processed. 5A and 5B show three mounts 1c and 1d as typical examples.
1e is shown. After forming the first layer 3 and the second layer 4 on both sides of the concealing surface of the mounts 1c and 1e and the concealing surface of the mount 1d, respectively, the three layers of the mounts 1c, 1d and 1e are joined together. Are laminated as follows.

If the size of each mount is set to the size of two postcards or the size of two sealed letters, the integrated mount can be further folded. Also in this case, similarly to the embodiment (3), the first layer 3 and the second layer 4 are formed on the facing surface of the mount to be folded.
If the combined second layers 4 are fused and integrated, a postcard having a multilayered information display surface is obtained. If the first layer 3 and the second layer 4 are simply formed without being formed, a three-layer reciprocating postcard is used. Be a body.

The present invention is not limited to the above embodiment. For example, the embodiment (4) shows a case where three mounts are used as a typical example. However, the mount may be an information communication body in which a desired number of four or more sheets are stacked and multilayered by the above method. It is also possible to add a single reply postcard to the multi-layered information stack to form a reciprocating postcard. In this case, if the reply postcard is also multi-layered, more information display surfaces can be secured. In each embodiment, an opening means as shown in FIG. 6 may be provided. Reference numeral 6 denotes a discontinuous break such as a perforation, which is provided for convenience when peeling off from the pseudo-adhesion portion. Of course, continuous cuts such as slits can be provided. The location may be provided along the opening side end as shown in FIG. 6A, or may be provided at a part of the opening side end as shown in FIG. 6B. Instead of providing slits or perforations, one edge may be slightly displaced from the other, a notch may be provided at a corner, or the like may be folded, and a step (not shown) may be provided therebetween.

[0026]

When the second layers of the information display surface of the information communication body are opposed to each other and heated and pressed, the second layers are fused and integrated.
When the recipient applies force to peel and open the concealed surface,
Pseudo-adhesion part with low peel strength between the layer and the second layer or the second layer
It is peeled and developed from the middle of the layer. Therefore, it is impossible that the first layers are blocked from each other and cannot be separated.
Further, since there is no need to pay special attention to temperature and pressure adjustments during the heating and pressurizing treatments, it is suitable for mass processing using inexperienced persons. Furthermore, if the paper (S) is formed by form printing using a continuous long sheet, rotary printing, etc., then,
Feeding out a continuous long sheet, forming first and second layers, drying,
