Abstract

PURPOSE:To bond a cover material by proper adhesive strength and to enter data in postcard pasteboard by a method wherein a thermal adhesive resin layer is formed to the main surface of an adhesive strength adjusting layer so that a part thereof comes into contact with a hardly adhesive layer and a gap part having no thermal adhesive resin layer formed thereto is formed over the range from the main surface of the thermal adhesive resin layer to that of the adhesive strength adjusting layer. CONSTITUTION:A gap part 40 where a thermal adhesive resin layer 38 and an adhesive strength adjusting layer 36 are not formed is partially formed over the range from the main surface of the thermal adhesive resin layer 38 to that of a hardly adhesive layer 34. Since the adhesive strength adjusting layer 36 is formed between a cover material 24 and the thermal adhesive resin layer and strongly bonds the cover material 24 and the thermal adhesive resin layer 38 and bonds the cover material 24 and the adhesive strength adjusting layer 36 by properly controlled low adhesive strength, the cover material 24 is bonded to postcard pastboard 22 by proper and stable adhesive strength. A recipient peels off the cover material 24 from the postcard pasteboard 22 and can apply a seal and writing to the postcard pasteboard 22 by the gap part 40.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to postcards, and in particular, for example, the confidential information part is hidden during mailing, and the official receipt is concealed after the recipient receives the postcard. Concerning postcards whose top parts can be viewed as appropriate.

(Prior art) In recent years, there has been an increase in the number of mail items containing confidential information, such as notices of bank account balances, etc. However, the field for writing confidential information is hidden during mailing, and the recipient receives the official receipt. Postcards have been developed that are shaped so that their contents can be viewed relatively easily after being removed.

FIG. 16 is a partial sectional view of a conventional postcard of this type.

This postcard 1 is a postcard mount 2 shaped to the size of an official postcard.
This includes a covering material 3 stuck to a part of the postcard mount 2. This covering material 3 includes a base material 4 . An adhesive layer 5 is formed on one main surface of the base material 4 . On one main surface of the adhesive layer 5,
A concealing layer 6 made of aluminum is formed. The base material 4 and the hiding layer 6 are bonded together by an adhesive layer 5. hidden layer 6
A release agent layer 7 is formed on one main surface. A thermoadhesive resin layer 8 is formed on one main surface of the release agent layer 7 . A postcard mount 2 is formed on one main surface of the thermoadhesive resin layer 8 . In the covering material 3, a heat-adhesive resin layer 8 is heated and melted, and is adhered to the postcard mount 2.

However, in the conventional postcard 1, even when the coating material 3 is heated and pressurized and attached to the postcard mount 2, it is difficult to attach it with an appropriate and stable adhesive force.

That is, if the adhesive force is too strong, the postcard mount 2 may be damaged when the covering material 3 is peeled off from the postcard mount 2. Moreover, if the adhesive strength is too weak, there is a risk that a part of the covering material 3 will peel off, for example, while the postcard 1 is being mailed.

FIG. 17 is a partial sectional view showing a postcard 1 in which a covering material 3 is adhered to a postcard mount 2 with an appropriate and stable adhesive force in order to solve these problems.

This postcard 1 includes a postcard mount 2 formed to the size of an official postcard and a covering material 3 stuck to a part of the postcard mount 2. A cutting cut 9 is formed in the covering material 3. This covering material 3 includes a base material 4 . An adhesive layer 5 is formed on one main surface of the base material 4 . A concealing layer 6 made of aluminum is formed on one main surface of the adhesive layer 5. hidden layer 6
A difficult-to-adhesion layer 10 is formed on the surface. Difficult adhesive layer 10
Adhesive force adjustment layer 11 is formed on one main surface of.

A thermoadhesive resin layer 8 is formed on the surface of the difficult-to-adhesion layer 10 on the adhesive force adjustment layer 11 side. A postcard mount 2 is formed on one main surface of the thermoadhesive resin layer 8 . In the covering material 3, a heat-adhesive resin layer 8 is heated and melted, and is adhered to the postcard mount 2.

Then, at the tip of the covering material 3, there is a linear adhesive part 12 in which the adhesive force adjustment layer 11 is not formed so that the difficult-to-adhesive layer 10 and the thermoadhesive resin layer 8 are directly adhered in a linear manner. do. In the line-shaped adhesive portions 12 where the adhesive force adjustment layer 11 is not formed, the difficult-to-adhesion layer 10 and the heat-adhesive resin layer 8 are strongly adhered. Moreover, the difficult-to-adhesion layer 10 and the adhesive force adjustment layer 11 are bonded together with a moderately controlled weak adhesive force. Therefore, by cutting at the cutting cut 9, the covering material 3 can be easily peeled off from the postcard mount 2. Then, on the surface of the postcard mount 2, an information section 13 is formed in which confidential information and the like are written.

On the surface of the heat-adhesive resin layer 8, the covering material 3 is adhered to the postcard board lff12. The information section 13 can be seen through the heat-adhesive resin layer 8 and the adhesive force adjustment layer 11.

(Problems to be Solved by the Invention) However, with the previously proposed postcards, it was difficult to stamp or write on the postcard mount after the covering material was peeled off from the postcard mount. As a result, the person receiving the official receipt was unable to write information on the postcard mount.

Therefore, the main object of the present invention is to allow a regular receiver to relatively easily peel off the covering after picking up the receiver and see the information underneath, and to be able to see the information underneath. The purpose of a regular receiver is to provide a postcard that is affixed to a postcard mount with a moderately stable adhesive force and allows the recipient to write information on the postcard mount.

(Means for Solving the Problems) The present invention includes a postcard mount and a covering material that is attached to the postcard mount and covers at least a part of the postcard mount, and the covering material covers a small portion of the base material (at least a portion of the surface thereof). A difficult-to-adhesive layer is formed on the main surface of the difficult-to-adhesive layer, an adhesive force adjustment layer is formed on the main surface of the difficult-to-adhesive layer, and a thermoadhesive resin layer is formed on the main surface of the adhesive force-adjustable layer, a part of which is in contact with the difficult-to-adhesive layer. A gap where the heat-adhesive resin layer is not formed is formed from the main surface of the heat-adhesive resin layer to the main surface of the adhesive force adjustment layer, and the covering material is formed by melting the heat-adhesive resin layer. It is a postcard attached to a postcard mount.

(Function) The heat-adhesive resin layer formed on the back side of the covering material is heated and pressurized on the surface of the postcard mount, thereby melting the heat-adhesive resin layer and pasting it onto the postcard mount. Ru. An adhesive force adjustment layer is formed between the difficult-to-adhesive layer and the heat-adhesive resin layer. The difficult-to-bond layer is strongly bonded to the heat-adhesive resin layer. Further, the adhesive force adjustment layer is weakly bonded to the difficult-to-adhesion layer.

Therefore, the difficult-to-adhesion layer and the heat-adhesive resin layer are strongly adhered, and the difficult-to-adhesion layer and the adhesive force adjustment layer are adhered to each other with an appropriately controlled weak adhesive force. Therefore, the covering material is adhered to the postcard mount with an appropriate and stable adhesive force.

Further, a void portion in which no heat adhesive resin layer is formed is formed from the main surface of the heat adhesive resin layer to the main surface of the adhesive force adjustment layer. Therefore, an authorized receiver can write information on the postcard mount by filling in the gap after peeling off the covering material from the postcard mount.

(Effects of the Invention) According to the present invention, when the covering material is peeled off from a single piece of postcard, the adhesion adjustment layer is formed between the covering material and the thermoadhesive resin layer, so that the covering material is With stable adhesive strength,
It is attached to the postcard mount.

Moreover, since there is a gap in which the heat-adhesive resin layer is not formed from the main surface of the heat-adhesive resin layer to the main surface of the adhesive force adjustment layer, it is difficult for regular receivers to remove the postcard from the postcard mount. After peeling off the covering material, it is possible to stamp, write, etc. on the postcard mount through the gap, and information can be written on the postcard mount.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a partial sectional view taken along line 1--2 in FIG.

This postcard 20 includes a postcard mount 22 formed to the size of an official postcard and a covering material 24 attached to a part of the postcard mount 12. This covering material 24 has cut-off cuts 26.
is formed.

The covering material 24, which is pasted on the surface of the postcard mount 22, particularly on the part where the line-forming part for secret matters such as financial and insurance information is formed, is mainly based on FIG. explain.

The covering material 24 includes a base material 28 made of a material that is relatively flexible and can be cut by hand or with scissors, such as a paper 9 synthetic resin film.

An adhesive layer 30 is formed on one main surface of the base material 28 . As the adhesive forming this adhesive layer 30, for example, an emulsion such as a polyvinyl acetate emulsion,
These include latex adhesives, water-soluble adhesives such as water glass and casein, and solvent-based reactive adhesives such as polyurethane.

A concealing layer 32 is formed on one main surface of the adhesive layer 30. This hiding layer 32 is formed by laminating film materials having a hiding power, such as aluminum foil with a thickness of 7 μm, with the adhesive force of the adhesive layer 30.
It may be formed by printing to a thickness of 0 μm.

When the concealing layer 32 is formed of an ink having a concealing property, the adhesive layer 30 is not necessary.

On the surface of the hiding layer 32, a difficult-to-adhesive layer 34 is formed by extruding an inert, non-polar resin such as polyethylene or polypropylene, and laminating the layer to a thickness of, for example, 10 to 20 μm.
It is formed to a thickness of m.

Note that if the hard-to-adhesion layer 34 is concealed by adding a concealing filler such as carbon black or aluminum powder, the concealing layer 32 does not need to be formed.

An adhesive force adjustment layer 36 is formed on one main surface of the difficult-to-adhesion layer 34 to have a thickness of, for example, 1 to 5 μm.

On the surface of the hard-to-adhesion layer 34 on the adhesive force adjustment layer 36 side, a thermally adhesive resin that adheres to the polyolefin resin of the hard-to-adhesion layer 34 is applied.
The thermoadhesive resin layer 38 is formed to a thickness of, for example, 10 to 30 μm by extrusion coating while heating, or by dissolving it in a solvent or dispersing it in water and performing printing such as gravure or silk screen.

This thermally adhesive resin layer 38 is heated at a temperature of, for example, 60°C to 20°C.
It is formed so that it softens and melts at a temperature of 0° C. and can be completely adhered to the postcard mount 22.

In addition, a gap 40 in which the thermal adhesive resin layer 38 and the adhesive force adjustment layer 36 are not formed is formed in a part from the main surface of the third-day thermal adhesive resin layer to the main surface of the difficult-to-adhesion layer 34. . Note that the void portion 40 may be formed only from the main surface of the heat-adhesive resin layer 38 to the main surface of the adhesive force adjustment layer 36.

The cutting cuts 26 are formed slightly inside the left and right ends of the adhesive force adjustment layer 36 . Moreover, the cutting cut 26 is
Base material 28. Adhesive layer 30. Hidden layer 32. Difficult adhesive layer 34
．． It is formed on both the upper and lower ends of the adhesive force adjustment layer 36 and the thermal adhesive resin layer 38.

Then, at the tip of the covering material 24, the hard-to-adhesion layer 34 and the heat-adhesive resin layer 38 are directly bonded in a line shape.
Line-shaped adhesive portion 4 in which adhesive force adjustment layer 36 is not formed
2 exists. In the line-shaped adhesive portion 42 where the adhesive force adjustment layer 36 is not formed, the difficult-to-adhesion layer 34 and the heat-adhesive resin layer 38 are strongly adhered. Furthermore, the difficult-to-adhesive layer 34 and the adhesive force adjustment layer 36 are bonded together with moderately controlled weak adhesive force. Therefore, the covering material 24 can be easily peeled off from the postcard mount 22 by cutting it off at the cutting cut 26.

Then, on the surface of the postcard mount 22, an information section 44 is formed in which confidential information and the like are written. In addition, the information department 44
In order to be able to see through the thermal adhesive resin layer 38 and the adhesive force adjustment layer 36, the thermal adhesive resin layer 38 and the adhesive force adjustment layer 36 need to be transparent or translucent.

In addition, this information part 44 can be used as a lottery part, and this postcard 20 can also be used as a postcard with a lottery.

The covering material 24 is adhered to the postcard mount 22 on the surface of the thermoadhesive resin layer 38 .

FIG. 3 is a partial sectional view showing a state in which the postcard 20 is cut off at the cutting cut 26 and the covering material 24 is peeled off, and FIG. 4 is a perspective view thereof.

The information section 44 can be seen through the heat-adhesive resin layer 38 and the adhesive force adjustment layer 36.

In addition, after peeling off the covering material 24 from the postcard mount 22, the authorized receiver passes the postcard mount 22 through the gap 40.
It is possible to stamp or write information on the postcard mount 22.

In addition to the above embodiments, examples of the base material 28 include synthetic paper, cellophane, polyethylene, polyester films, and aluminum foil. , difficult-to-adhesive layer 34
This coating material 2 resists the adhesive force between
It is better to select one that is relatively flexible so that the layer 4 does not peel off inadvertently.

Furthermore, if a material with excellent hiding properties, such as aluminum foil, is selected as the base material 28, it is not necessary to form the hiding layer 32 as in the previous embodiment.

The material of the adhesive force adjustment layer 36 is selected in relation to the difficult-to-adhesion layer 34. For example, when polyethylene is selected as the resin for forming the difficult-to-adhesion layer 34, the adhesive force adjustment layer 36
For example, polyvinyl methyl ether,
Polyvinylethyl ether, polyvinyl isobutyl ether, carboxyl-modified acrylic resin, polyamide resin, chlorinated polypropylene, ethylene/acrylic acid copolymer, ethylene/vinyl acetate copolymer, ethylene/ethyl acrylate resin, styrene/butadiene/styrene block copolymer Polymers, styrene/isoprene/styrene block copolymers, polyester resins, terpene resins,
Rosin, ester rosin, hydrogenated rosin, polymerized rosin, butyral resin.

Possible choices include petroleum resin, waxes such as polyethylene wax, paraffin wax, monk wax, and microcrystalline wax, vinyl chloride/vinyl acetate copolymer, and nitrocellulose. Then, the adhesion force adjusting layer 36 can be formed by coating these alone or a mixture of two or more types.

According to the inventor's experiments, in the above embodiment, a mixed solution of chlorinated polypropylene and vinyl chloride/vinyl acetate copolymer was applied to the polyolefin resin layer, that is, the difficult-to-adhesion layer 34, and the adhesion force adjustment layer 36 was formed. When the blending ratio is 40 to 240 parts of chlorinated polypropylene to 100 parts of vinyl chloride/vinyl acetate copolymer, the best results are obtained when 120 parts of chlorinated polypropylene is blended. It was done.

Further, in the above embodiment, a mixed solution of a block copolymer of styrene/butadiene/styrene and a vinyl chloride/vinyl acetate copolymer is applied to the polyolefin resin layer, that is, the difficult-to-adhesion layer 34, and an adhesive force adjustment layer is formed. 36 and their blending ratio is 1 part to 40 parts of a block copolymer of styrene, butadiene, and styrene to 100 parts of vinyl chloride/vinyl acetate copolymer.
The best results were obtained when 10 parts of a butadiene-styrene block copolymer was blended.

As an example of the thermoadhesive resin, an EVA adhesive is selected. Its composition consists of EVA (ethylene-vinyl acetate copolymer resin), a tackifier, a wax, and an antioxidant, and a desensitizing agent and a filler may be added as supplementary agents.

The hard-to-adhesive layer 34 is made of this E which forms the thermally adhesive resin layer 38.
It adheres well to VA adhesives, but generally has difficulty adhering to other adhesives.

Examples of the tackifier include glycerin ester of partially hydrogenated rosin, glycerin ester of rosin, pentaerythritol modified rosin, petroleum resin, α-methylstyrene/vinyltoluene copolymer, terpene oil polymer, and terpene phenol polymer.

Waxes include paraffin wax, microcrystalline wax, low molecular weight polyethylene wax, and Fischer-Tropsch wax.

Examples include castor wax and chlorinated paraffin.

Examples of antioxidants include hindered phenol compounds, salicylic acid compounds, hensifhenone compounds, benzotriazole compounds, phosphorus compounds, sulfur compounds, and organometallic compounds.

Thermal adhesive resins other than the above examples include styrene-butadiene-styrene copolymer resin, styrene-isoprene-styrene copolymer resin, polyethylene, ethylene-ethyl acrylate copolymer resin, ethylene-acrylic acid copolymer resin, ethylene- Methyl acrylate copolymer resin, ethylene-methyl methacrylate copolymer resin, ethylene-methacrylic acid copolymer resin, ionomer resin, polymethylpentene resin, ethylene-vinyl alcohol copolymer resin, vinylidene chloride resin, vinyl chloride vinyl acetate copolymer resin , polyamide resin, styrene-acrylic copolymer resin, polystyrene resin, polyacrylic acid copolymer resin, polyester resin, polyurethane resin.

You can choose wax etc. When printing or coating these, they may be used as appropriate while being heated, dissolved in a solvent, or dispersed in water.

The covering material 24 is adhered to the postcard mount 22 by melting the thermoadhesive resin layer 38 by heating. If heating is performed only after confirming that the covering material 24 is superimposed on the postcard mount 22 at the optimum position, the covering material 24 can be accurately adhered to the optimum position on the surface of the postcard mount 22. Therefore, so-called pasting errors, such as not being pasted at the correct position, do not occur when pressure-sensitive adhesives are used.

Furthermore, since a cut-off cut 26 is formed in the covering material 24, even if the contents of the genuine receiver are seen by a third party who is not the recipient, the cut-off cut 26 will not be torn at that time. This allows the recipient to know that the contents of the genuine receipt have been viewed.

According to the present invention, the adhesive force adjustment layer 36 is formed between the covering material 24 and the heat-adhesive resin layer 38, and the covering material 24 and the heat-adhesive resin layer 38 are strongly adhered to each other. Since the force adjustment layer 36 is adhered with an appropriately controlled weak adhesive force, the covering material 24 is adhered to the postcard mount 22 with an appropriately stable adhesive force.

Therefore, if the adhesive force is too strong and the covering material 24 is peeled off from the postcard mount 22, the postcard mount 22 may be damaged, or if the adhesive force is too weak, the covering material 24 may be removed during mailing of the postcard.
No part of it will peel off.

In addition, after peeling off the covering material 24 from the postcard mount 22, the authorized receiver removes the covering material 24 from the postcard mount 22, and then removes the postcard mount 22 from the gap 40.
It is possible to stamp or write information on the postcard mount 22.

In the embodiment, the adhesive force adjustment layer 36 is attached to the base material 28.
It is formed into a band shape with a gap 40 in the center at appropriate intervals in the width direction.For example, as shown in FIG. material 2
A spot-like portion where the adhesive force adjustment layer 36 is not formed may be provided near the longitudinal end edge of the adhesive layer 8 . In this way, a spot-like exposed portion of the heat-adhesive resin layer 38 will be formed near both edges of the base material 28, and when this covering material 24 is pasted on the postcard mount 22, In addition, the covering material 24 can be prevented from being inadvertently peeled off from the postcard mount 22 near the longitudinal edges of the base material 28.
