Description

TECHNICAL FIELD The present invention relates to a postcard for a printer and a method for manufacturing the postcard, and more specifically, a postcard used for the purpose of concealing information such as correspondence, particularly a laser printer or thermal transfer. Printers, etc.
A postcard that is used by printing with an automatic printing machine that prints letters and fixes ink for letters in a heated state. A synthetic resin layer is provided on the inner surface side of the entire postcard, and the inner surface side is heat-bonded. The present invention relates to a postcard for a printer and a manufacturing method thereof.

(Prior Art) Conventionally, as a postcard provided with the above-mentioned synthetic resin layer and having its inner surface side thermally bonded, there is, for example, one disclosed in Japanese Patent Laid-Open No. 16692/1989.

That is, in this postcard, a film is provided on the inner surface side of the two sheet pieces forming the postcard body, and the films can be peeled off via a pseudo adhesive layer.

(Problems to be solved by the invention) However, in the postcard as described above, since the film is provided on the inner surface side of the sheet piece, it is difficult to display information by printing or printing directly on the film. In this type of postcard, printing and displaying of information by printing had to be performed directly on a paper sheet piece before the film was attached to the sheet piece.

In the printing before sticking such a film, for example, when information is displayed by printing, such as a postcard for direct mail, the paper seal is directly printed by the printer, and then the film processor It is easy to adapt the manufacturing process of the product, such as sticking, to the distribution process of general product processing, and the manufacturing work can be performed rationally.

However, when printing character information with a printer such as a computer, from the viewpoint of confidentiality of information, banks, securities companies, and other companies that use this type of postcard often print it in-house. It is required that after printing, the system be maintained so that it can be quickly mailed through the process of bending, adhering, etc.

Therefore, in such a case, it is impossible for the above financial institutions, companies, etc. to attach the film after printing, the production process does not match the general product distribution process, and it is impossible to do it in the work process. Will occur.

For this reason, the conventional postcard provided with the synthetic resin film as described above was used only for direct mail, but is not currently used for character printing by a printer or the like. there were.

The present invention has been made in order to solve the above problems, and is a postcard provided with a synthetic resin layer, it is possible to directly print the character information.
Suitable for production by printing characters on printers of companies,
Moreover, it is an object to provide a postcard that does not cause transfer of characters even after opening.

(Means for Solving the Problems) The present invention has been made as a postcard and a method for manufacturing the same in order to solve the above-mentioned problems, and the feature of the postcard is that the postcard main body 1 has at least two sheet pieces. Consists of
And in the postcard in which the resin layer 5 is provided on the inner surface sides of the sheet pieces that face each other, and the inner surface side of the sheet pieces is heat-bonded in a peelable manner via the resin layer 5, the resin layer 5 is
In printing characters on the resin layer 5, etc., the fixing agent for forming characters is softened or melted at the fixing temperature to fix the fixing agent for forming characters, and the fixing agent for forming characters is fixed on the sheet. It is composed of a resin that does not transfer to one side of the facing sheet even after peeling the piece.

In other words, the resin forming the resin layer 5 is a resin having a softening and melting temperature lower than the melting temperature of the character forming fixing agent.

In other words, the resin forming the resin layer 5 is such a resin that the resin layers 5, 5 facing each other can be heat-bonded at a temperature equal to or lower than the melting temperature of the character forming fixing agent.

Further, a feature of the postcard manufacturing method is that a resin layer 5 is provided in advance on the inner surface sides of the postcard body 1 which can be folded in at least two, facing each other, and the resin layer 5 is softened or melted by heating. A character-forming fixing agent is fixed on the resin amount 5 to print characters, and then the postcard body 1 is bent to polymerize between the bent sheet pieces,
In addition, by heating at a temperature lower than the fixing temperature of the character-forming fixing agent, the polymerized sheet pieces are heat-bonded to produce the sheet.

(Operation) When a postcard having the above-mentioned configuration is used, first, necessary information is printed and displayed on the inner surface of the sheet piece.

In this case, since the resin layer 5 capable of fixing the character-forming fixing agent by softening or melting at the fixing temperature of the character-forming fixing agent is provided on the inner surface side of the sheet piece, at the time of printing by the printer, When the resin amount 5 is softened or melted by heat, the character forming fixing agent is immersed in the softened or melted resin layer 5, and the synthetic resin layer 5 is formed.
The character-forming fixing agent is reliably fixed on the upper surface.

Next, after printing characters as necessary information as described above, the postcard body 1 is bent to polymerize the sheet pieces with each other, and the polymerized sheet pieces are fixed to the fixing temperature of the character forming fixing agent. When heated and pressed at a lower temperature than
Since the resin layer is heat-adhesive, the sheet pieces are 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 image of the sheet piece by separating the sheet pieces of the postcard. In this case, since the resin layer 5 is peelable as described above, peeling between the sheet pieces can be easily performed, and
The displayed information does not transfer from one sheet piece to the other sheet piece side. In other words, if the sheet pieces are heat-bonded at a temperature lower than the temperature at which the fixing agent for forming characters is fixed, the fixing force of the characters to the resin layer 5 is such that the characters are not transferred to the resin layer 5 on the facing side. It is larger than the force to transfer, and therefore the transfer of characters after peeling is surely prevented.

(Example) Hereinafter, the Example of this invention is described according to drawing.

FIG. 1 shows a postcard as one embodiment, (A) is a front view, (B) is a rear view, and (C) is an enlarged cross-sectional view taken along the line AA of (A).

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 sheet piece 1a to display the destination / address by printing with a laser printer, and an information display unit on the inner surface side of both sheet pieces 1a and 1b. 3a and 3b are provided, and on the inner surface side thereof, a resin layer 4 made of polypropylene and an ionomer [copolymer of ethylene containing a carboxyl group (for example, ethylene-acrylic acid copolymer resin) are used. Two synthetic resin layers are provided, including a resin layer 5 made of an alkaline earth metal having metal ion bonds introduced between polymer main chains], [trade name Surlyn; registered trademark of DuPont]. Then, characters as necessary information are printed by a laser printer on the inner surface side of the resin layer 5 on the inner surface side.

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 6 so that
In addition, the entire surface between the sheet pieces 1a and 1b is heat-bonded in a peelable manner via the heat-adhesive resin layer 5.

Reference numeral 7 denotes an advertisement / advertisement section provided on the outer surface side of the sheet piece 1b.

Note that the recipient who receives the postcard 8 can read the information displayed on the information display portions 3a, 3b by separating the sheet pieces 1a, 1b as shown in FIG. 2 to develop the postcard. Becomes

Further, since the characters are printed on the resin layer 5 as described above, there is an advantage that the characters are printed more clearly.

Next, a method of manufacturing the above postcard will be described. First, as shown in FIG. 3, a postcard forming sheet 9 having a size four times the size of a postcard is prepared.

That is, the postcard forming sheet 9 is formed by further vertically connecting two postcard forming pieces 10 formed by connecting two postcard-sized sheet pieces 1a and 1b. It has a structure in which the above-described two resin layers 4 and 5 are provided on the upper surface.

Next, the information display portions 3a, 3 of the postcard forming paper 9 as described above.
Characters as predetermined information are printed on the side b by a laser printer as shown in FIG.

In this case, printing is performed at a heating temperature of about 180 ° C., but since the resin layer 5 made of the ionomer on the inner surface side has a melting point lower than 180 ° C., it is easily softened and melted to form characters. Since the fixing agent (toner) is immersed in the resin layer 5 and the toner is also softened at this heating temperature, the toner is reliably fixed to the resin layer 5, and the printing is surely performed.

Next, as shown in FIG. 5, the postcard forming sheet 9 is cut into two pieces, and the cut postcard forming piece 10 is cut into two pieces.
Fold it in two so that a and 3b are on the inner surface side, and heat and pressure bond at a temperature of about 100 ° C to polymerize and bond the inner surface sides of the sheet pieces 1a and 1b to each other so that a postcard 8 as shown in Fig. 1 is obtained. It will be manufactured.

In this case, the heat-bonding is performed at a temperature of about 100 ° C., which is lower than that at the time of printing, but the synthetic resin layer 5 made of the ionomer softens at this temperature, and therefore the resin layers 5, 5 facing each other are formed. These will be heat-bonded to each other.

However, since the toner does not melt at a temperature of about 100 ° C., the adhesive force between the resin layers 5 and 5 is weaker than the immersion force of the toner into the resin layer 5.

Therefore, even when the sheet pieces 1a and 1b are peeled from each other, the characters are not transferred to the resin layer 5 facing each other, and the peeling between the sheet pieces 1a and 1b is very easy and smooth without any resistance. It can be done.

Next, FIG. 6 shows a postcard of another embodiment, in which (a) is a front view of the developed state, (b) is a rear view of the same, and (c) is an enlarged cross-sectional view of a folded and adhered postcard in the middle. Is.

In this embodiment, the postcard body 1 has three sheet pieces 1a, 1b, 1c.
The address and address display section 2 is provided on the front side of one side sheet piece 1a, and the information display sections 3a and 3b and the two resin layers 4 and 5 are the intermediate sheet piece 1b. And on the front surface side of the other side sheet piece 1c. Further, the advertisement section 7 is provided on the back side of the other side sheet piece 1c.

Then, the postcard main body 1 is bent into a substantially Z shape, and the front surface side of the central sheet piece 1b and the other side sheet piece 1c are faced to each other so that they are heat-bonded so as to be peelable via the resin layers 5 and 5. Has been done.

Further, one side sheet piece 1a and the center sheet piece 1b face each other so that the back surfaces thereof are the inner surfaces, and are non-separably bonded via an adhesive 12.

In this embodiment, after opening the postcard, the other side sheet piece 1c and the center sheet piece 1b are peeled off as shown in FIG. 7, but the center sheet piece 1b and one side sheet piece 1a are separated. Is still bonded via a non-peelable adhesive 12, so at least the central sheet piece 1b and one side sheet piece 1b
1a means that it can be handled like one sheet piece,
Only the other side sheet piece 1c and the central sheet piece 1b are in a developed state.

Therefore, the postcard after opening will be unfolded as if it were folded in half, and unnecessary fields will not be exposed, and only the originally necessary information display fields will be exposed. For a person, there is an effect that the information display field can be detected very easily and immediately after opening.

Further, between the central sheet piece 1b and the other side sheet piece 1c, since they are bonded via an adhesive provided on the entire surface, before opening the air layer does not inadvertently enter,
Therefore, the thickness of the postcard does not increase carelessly. As a result, there is an advantage that a postcard that meets strict standards such as thickness and weight can be provided.

Next, FIG. 8 shows a postcard as another embodiment, in which (a) is a front view and (b) is an enlarged cross-sectional view taken along the line DD of (a).

In this embodiment, the postcard body 1 has three sheet pieces 1a, 1b, 1c.
In addition, the destination and address display section 2 is provided on the front surface side of one side sheet piece 1a, and the information display sections 3a and 3b are provided on the center sheet piece 1b and the other side. It is provided on the front surface side of the side sheet piece 1c.

Then, the central sheet piece 1b and the other side sheet piece 1c are
Fold it so that the information display portions 3a and 3b are on the inner surface side and that only one side sheet piece 1a provided with the destination / address display portion 2 is projected from the other sheet pieces 1b and 1c. It is bent through the curved portion 6 and is detachably bonded through the two resin layers 4 and 5. Further, in the folded state, the postcard main body 1 is formed so that the overall size of the postcard body 1 conforms to the standard size of the postcard.

In the postcard 8 of this embodiment, in the folded state as described above, only the one side sheet 1a having the destination / address display portion 2 has the central sheet piece 1b having the information display portions 3a and 3b and the other side sheet 1a. Since the sheet piece 1c is protruded to the outside of the sheet piece 1c and is in a bare state, the concealing function of the information display sections 3a and 3b and the mailing function of the destination / address display section 2 are not impaired at all, and the destination, address, communication, etc. Since the description can be made on the same side of the postcard main body 1, the above-described predetermined items can be described by automatic printing by a printer of a computer,
There is an effect that it is possible to automatically and mass-produce this type of two-fold type confidential postcard.

In addition, since the postcard main body 1 is formed in the standard size of the postcard in the folded state, there is an advantage that the postcard can be mailed in conformity with the postal method.

In addition, the postcard body 1 is folded in two, as in each of the above-described embodiments.
It does not matter about the type such as folding, and its form is not limited to the above-mentioned embodiments. Also, in the above embodiment, 2 sheets, 3 sheets
The postcard main body 1 is configured by connecting and bending a plurality of sheet pieces, but not limited to this, for example, two or more sheet pieces are formed separately, and the separate sheet pieces are bonded together. The postcard main body 1 may be configured by. The point is that the postcard body 1 may be composed of at least two sheet pieces, whether they are integrated or separate.

Further, in the above-mentioned embodiment, the ionomer is used as the material of the resin layer 5 on the inner surface side which can be heat-bonded so that it can be peeled off. However, the material of the resin layer 5 is not limited to this and, for example, ethylene- It may be a vinyl acetate copolymer resin, an ethylene-ethyl acrylate copolymer resin, an ethylene-acrylic acid copolymer resin, an ethylene-maleic anhydride-acrylate copolymer resin, a polyester adhesive resin, or the like.

The point is that the resin layers 5 and 5 can be thermally adhered to each other in the superposed state of the sheet pieces, and the sheet pieces can be peeled off after the adhesion, and moreover, by the heat when fixing the character forming fixing agent such as toner. It suffices that the character is made of a resin that can be softened or melted to print the character and that the character is not transferred even after the sheet pieces 1a and 1b are peeled off. Therefore, the resin is not limited to the synthetic resin and a natural resin may be used as long as the above conditions are satisfied.

Further, in this embodiment, a synthetic resin made of polypropylene is used as the resin layer 4 on the outer surface side, but the material of the resin layer 4 on the outer surface side is not limited to this. Resin, etc.
Any synthetic resin can be used. In any case, as long as the resin layer on the outer surface side does not melt or flow at the time of fixing the character-forming fixing agent, the two resin layers do not melt even after printing the characters. Of.

Furthermore, as a synthetic resin film as a finished product composed of such two resin layers 4 and 5, for example, Tocello CM
Heat sealable lure mirror (trade name: Toray) using PS film (special sealant film) [trade name: Tohcello Chemical Co., Ltd.] and biaxially oriented polyester coextrusion film
It is also possible to use the east.

It should be noted that two layers of the synthetic resin on the inner surface side and the outer surface side are preliminarily laminated by the resin layer 4 on the outer surface side, and the two synthetic resin layers are attached to the paper via the synthetic resin layer on the outer surface side. This has the advantage that the work for forming the postcard main body such as laminating and sticking can be easily performed, but the resin layer 4 on the outer surface side is not essential to the present invention.

Further, in the above embodiment, the postcard main body 1 is composed of only paper, but the structure of the postcard main body 1 is not limited to this, and for example, as shown in FIG. 9, aluminum vapor deposition is performed between two sheets of paper 13, 13. It may have a three-layer structure with an opaque sheet 12 made of a film interposed. In this case, the information display
It is possible to obtain a preferable effect that the information of 3a and 3b can be prevented from being seen through from the outside.

As the means for preventing the see-through, other than the three-layer structure as described above, any means such as coloring the inner surface side of the postcard body 1 on which information is not displayed can be used.

Furthermore, in each of the above embodiments, the entire inner surface side of the sheet piece is adhered, but it is not necessary that the entire surface is adhered. For example, a part of the non-adhesive portion is formed and peeled to the non-adhesive portion. Impossible adhesive may be provided.

Further, in the above embodiment, the sheet pieces are bonded together by heating at the same time during the polymerization, but the heat bonding may be carried out after the polymerization, or may be carried out by applying pressure after the polymerization and heating. The procedure does not matter.

Further, in the above embodiment, the case where the information is printed by the laser printer has been described. However, the information is not limited to the laser printer, and may be printed by another thermal transfer printer. In short, it is only necessary to use a printer in which the resin layer 5 is softened and heated at a temperature at which characters can be printed during printing.

In the present invention, the main purpose is to use a paper material as the postcard main body 1, such as one made of only paper as in the above embodiment, one having an aluminum vapor deposition film interposed between the paper, and the like. 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.

(Effects of the Invention) (a) As described above, according to the present invention, the postcard body is composed of at least two sheet pieces, and the resin layer is provided on the inner surface sides of the sheet pieces facing each other. In a postcard in which the inner surface side of the sheet piece is releasably heat-bonded via a layer, the resin layer is at the time of character printing on the resin layer,
Since it is composed of a resin that softens or melts at the fixing temperature of the character forming fixing agent that forms the character to fix the character forming fixing agent, the resin layer is formed by heat during printing by the printer. The fixing agent for fixing characters is fixed on the resin layer while being softened and melted, and characters are reliably printed on the resin layer.

Therefore, even though it is a postcard having a resin layer provided on the inner surface side, it is possible to print directly on the resin layer, and therefore, for example, in a financial institution such as a bank, a securities company, or each company,
In the case of printing in-house, it is possible to print directly on postcards as a finished product equipped with a resin layer, so it is possible to perform mailing work very rationally compared to the above-mentioned conventional postcards. It has a remarkable effect.

(B) Furthermore, since the resin forming the resin layer on the inner surface side does not transfer the fixing agent for character formation to the facing sheet piece side even after peeling the sheet piece, Even after the peeling, the displayed characters are not transferred from one sheet piece to the other sheet piece side.
