Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a deployable laminated card, and more particularly, the present invention relates to a deployable laminated card, and more particularly, the present invention relates to a deployable laminated card that is bonded together through a film composite having a peelable composite surface therein. Regarding cards.

(Prior Art) When a thermoplastic resin of a different type, such as polyethylene resin, is supplied in a molten state to a specific thermoplastic resin film, such as polyethylene terephthalate or oriented propylene film, and is pressed together, the gap between them is A unique adhesive surface is created by wetting. The adhesive surface of such a film composite does not easily peel off or shift under normal handling, but if necessary, a peeling force in a 90° or 180° direction may be applied to the adhesive surface. The constituent resin layers on both sides of this surface as a boundary are peeled off from each other, and the surface after peeling does not exhibit any adhesiveness. This special adhesive surface (hereinafter referred to as the lead adhesive surface in some cases)
In recent years, film composites having the following have been gradually put into practical use as constituent materials for multi-layered display labels or cards with coated stickers (for example, Utility Model Application No. 61-204729, etc.).

(Issues to be solved by the invention) The above-mentioned multi-layer display labels and cards with cover stickers, etc. usually require a transparent film composite to be applied to the surface of the card base material on which the display is usually written or printed. It is formed by adhering a covering seal, which normally hides the display on the card substrate surface, and if necessary, when the covering seal is peeled off, the covering seal is removed from the lead adhesion surface between the resin layers of the film composite. The display is readable through the transparent resin film on one side of the film composite that is separated and left on the base material surface.

In such cases, the cover sticker that is peeled off from the card base material side is, in most cases, discarded as it is after being peeled off from the card, but for example, when the cover seal is peeled off, it is necessary to connect it to the card base material side. It is also possible to use it in a two-page spread format. In such double-page spread or expandable cards, the inner part of the covering seal, which was conventionally discarded, can also be used as an information writing surface, and it is expected that it will be possible to provide, for example, postcards and other practically useful articles. The simplest structure for this is, for example, if the opposite sides of a folded card are glued together using the film composite so that they can be spread open, the information on the front and back four sides (two pieces) can be combined into one card. It will be contained.

However, most commercial printers used for computer printing of different destinations and data for a large number of customers employ a single-sided printing format. For this reason, for example, if one side (half) of the front side of the card is used to print the destination (and sender's) address, which is essential for postcards, the remaining side (half) can only be used for data printing, and the back side, which is folded, can be used for printing the data. can only be used to pre-print fixed items such as advertisements and messages. Furthermore, if the front two sides are used to print necessary data, etc., it becomes necessary to display the address etc. on the back side by some means, which causes the trouble of having to double the printing process.

Therefore, even if it is possible to substantially increase the amount of stored information by using a stacked card format, some kind of ingenuity is required to make the card compatible with the intended use or with current printers.

(Means for Solving the Problems) The problem with the prior art is that a sheet with a predetermined print on the surface is folded into three so that one door section faces the back surface and the other door section faces each other on the center surface. A card base material having a three-layer structure and at least two thermoplastic resin layers of different materials releasably fused to each other by pressure bonding in a molten state, and between at least one opposing surface of the card base material. The present invention is solved by a developable laminated card characterized in that it consists of a film composite that is adhesively sandwiched between.

Note that a card with a four-layer structure obtained by further bending the three-layer structure card base material at one of the folded door portions is also useful depending on the application.

Furthermore, the multilayered card may be made removable by using the film composite on all of its opposing surfaces, or it may be secured to at least one opposing surface by conventional adhesives.

The film composite used in the card basically has a peelable composite surface formed by pressing two different thermoplastic resin layers together in a molten state, at least one of which is cooled and solidified. ing.

(Function) A card base material with printing on each part of one side is folded into three in a Z-shape, and one opposing side is bonded via a film composite having a peelable composite surface, for example. The other facing surfaces are fixed with a common adhesive or the like. As a result, for example, the display on the one facing surface on which data etc. are printed is always covered from the outside by folding the sheet,
Then, the surface on which the destination address and the like are printed is folded and adhered to the combined body resulting from this folding, thereby forming a card with an integrated appearance.

When a peeling force is applied in a 90° or 180° direction to the one opposing surface of such a card, the peel strength of the composite surface (lead bonding surface) between the film layers of the sandwiched film composite increases with respect to the adhesive. Since the adhesive strength is extremely weak compared to the adhesive strength, the card always peels off along the composite surface of the film composite, and the central part and door part of the card are unfolded to the left and right. In this case, each film layer of the film composite is adhered to the surface of each base card, but
If each layer is made of a transparent film, there will be no problem in reading the writing on each surface.

In addition, such sheet folding can be easily performed by using a known form processing machine that processes continuous forms output from a computer, and can also be easily performed by bonding the film composite and card sheets together. It can also be easily carried out in a form suitable for mass production by using an ordinary gluing finishing machine or by using wet seal paper.

Furthermore, the card of the present invention can be folded into any number of cards, not just the three-fold format described above. For example, if the sheet is folded in four in a W-shape, the two sides in the center are the folding surfaces with lead adhesive, and the left and right doors that are folded outward are used as the address and other printing surfaces, then the four sides of the sheet are It can be used as an effective printing surface,
The back side without printing is used as the adhesive surface.
Of course, it is also possible to interpose a film composite on the adhesive surface to make more effective use of the writing surface.

Note that the composite surfaces of the film composite are always firmly attached by heat sealing applied to the ends of the films in addition to the lead adhesive force between the films. On the other hand, on the inside of this heat-sealed area on the lead adhesive surface, a peeling surface made of silicone or the like is formed to serve as a tension (peeling allowance) for peeling off the film composite using this lead adhesive surface as a boundary when the card is developed. It is preferable.

Embodiments The present invention will be explained in detail below with reference to embodiments shown in the drawings.

Embodiment 1 FIG. 1 is a perspective view of a card base material used in the developable laminated card of the present invention.

One side 2 is printed using a computer printer, etc.
A, 2B, and 2C are printed on the sheet 2, and the left side door 2B is made to correspond to the front side of the center part 2A, and the right side door part 2C is made to correspond to the back side of the center part 2A.
Fold into thirds along line b to the size of a postcard.

FIG. 2 is a longitudinal cross-sectional view of the film composite 3 used in the present invention, in which the film composite 3 is adhered to a pair of release papers 8, 8 through transparent pressure-sensitive adhesive layers 7, 7, respectively.
25 μm transparent polyethylene terephthalate film (hereinafter referred to as PET film) 4 and polyethylene terephthalate film (hereinafter referred to as PET film) whose surface has been subjected to corona discharge or anchor coating treatment.
A bonding layer 5 of transparent polyethylene resin (hereinafter referred to as PE resin) is placed between the PET film (hereinafter referred to as PET film) 6 at a temperature of 300 to 310, which is slightly lower than the normal lamination temperature.
It is melted at a temperature of .degree. C. and supplied in a layer thickness of about 20 .mu.m, and is pressed together with both films 4 and 6 and cooled. In this case, the PTE film 6 of the film composite 3 has a bonding layer 5 of PE resin due to its corona discharge machined surface.
However, the PET film 4 that has not undergone such processing is simply fused to the bonding layer 5 of PE resin by wetting during melting, solidifies during cooling, and has a peel strength (180°). A composite surface 4-5 with peeling of about 10 to 15 g/cm ² is formed. Although this composite surface 4-5 does not easily peel or shift due to the action of normal handling, if necessary, the film layers 4-5 may be separated by a 180° angle greater than the above value.
When a directional peeling force is applied, the film is easily peeled off, and no tackiness remains on the film surface after the peeling, which is the case when bonded with a normal pressure-sensitive adhesive.

At the time of manufacturing the card, as shown in FIG. The left door portion 2B and the center portion 2A are adhesively sandwiched, while the back surfaces of the center portion 2A and the right door portion 2C are fixed to each other with an ordinary pressure-sensitive adhesive M.

In this case, predetermined communication information 2A, 2B and destination 2C are printed on the front side of sheet 2 by the printer of the computer, so that 3
Even the entire surface is effectively used for writing information.

Further, as shown in FIGS. 2 and 3, a silicone peeling treatment zone 9 is formed on the developed end side of the composite surface 4-5 of the film composite 3, and a heat sealing treatment is further performed along the outer edge of the silicone peeling treatment zone 9. A region 10 is formed. In addition, C in the figure shows the developed end of the laminated card as the composite surface (lead adhesive surface) 4 of the film composite 3.
-5 is a cutoff line for providing a sharp peeling line formed so that it can be easily opened.

The addressee who receives such a card cuts out the heat-sealed area 10 of the laminated card along the tear line C, for example, to expose the end face of the peeled area 9 of the lead adhesive surface 4-5 of the film composite 3. .

If the sheets 2A and 2C of the laminated card are peeled off in the vertical direction in the figure in this state, the film composite 3 is easily separated into the film 4 and the film 5 along the composite surface 4-5 by this peeling action. Along with this, the card base material 1 becomes a card state in which the central portion 2A and the left door portion 2B are expanded. In this case, the printing and other descriptions on the sheets 2A and 2B of the card base material can be read through the transparent films 4, 6, and 5. Further, once the card is developed in this manner, no adhesive remains on the composite surface of the film composite 3, so that it is impossible to restore the card to its original state.

In addition, when using this laminated card as a postcard, etc., the lead adhesive surface 4-5
It is desirable that the films do not peel off easily during the process, but this is achieved by bonding the films together with appropriate peeling force through lead adhesion, and in particular by applying heat-sealed areas 10 to the side edges of the film composite 3 along the peeled end surface of the card. This can be achieved reliably by implementing

As described above, according to the embodiment of the present invention, it is possible to obtain a laminated card in a folded state in which a specific writing surface is covered by using the film composite 3, and particularly in the form of this card. Accordingly, the entire surface of the card base material 1 can be used for printing, for example, correspondence, and the amount of information carried on the card base material 1 can be increased.

Example 2 This example shows a structure in which the card sheet of Example 1 is folded into four. As shown in Figure 4, sheet 1
The central portions 12A, 12B of 2 are folded in the direction of arrow c with their surfaces (printed surfaces) facing each other, and a film composite (not shown) having a lead adhesive surface is adhesively sandwiched between the opposing surfaces. Also sheet 12
The door portions 12C and 12D at both ends of the card are folded back along the direction of arrow a with the printed surfaces facing up, and fixed with an adhesive to form a single laminated card. In this case, the entire surface of the sheet 12 (4 of 12A-12D)
All sides (sides) are effectively used for printing, while the back side of the sheet is used for gluing the sides of the card together.

Note that as the number of folding sections increases, the thickness and weight of the entire card also increase, so it is desirable to make the thickness of the film composite as thin as possible. For this purpose, a composite consisting of the PE resin layer 5 and the PET film 4 may be used by removing the PET film 6 on the side subjected to electrical discharge machining from the film composite 3 of Example 1. Other structures and functions are basically the same as those shown in FIG.

In addition, the present invention is not limited to the illustrated embodiment, and various modifications are possible. For example, for postcards, the Z-shape, that is, the three-layer structure is preferable from the viewpoint of weight limitations, but depending on the application, a four-layer structure as in Example 2 or a multi-layer structure may be used. Furthermore, in the case of a three-layer structure, the Z-shaped structure described above is preferable from the viewpoint of manufacturing and handling, but a structure in which the left and right doors overlap each other on the same side of the central part is also possible. Used in some cases.

(Effects of the invention) As described above, according to the invention, sheets printed on multiple sides can be integrated into one expandable card, which helps to maintain the confidentiality of information and increase the amount of information contained. Gives an excellent effect.
