Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a postcard and its continuous form that allow predetermined items to be sent easily and secretly.

(Prior Art) For various notifications and communications such as direct mail or bank transfer notices, so-called secret postcards, which allow notification matters to be sent secretly, have been commonly used.

Conventional postcards of this type are made by: ■ Folded paper twice the size of a regular postcard, or two stacked regular postcards glued together with a removable adhesive sticker between them. - A piece of paper pre-filled with heat sealant, folded in half and glued in a removable manner using a hot roll, etc. - A postcard with the addressee written on half of the address side, and the designated information on the other half. For example, there is a method in which a sticker is removably affixed to the remaining portion.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional postcards use adhesive stickers or stick-on stickers, not only do the postcards become expensive, but they also require printing and printing on the back of the stickers. Printing is not possible.

In addition, in the conventional postcards (■) mentioned above, paper with heat sealant applied is used, so the ink layer is thicker (at 180°C) by solid printing in several colors on the paper surface. If you do not heat-seal at high temperatures before and after, the sealant on the paper may not work sufficiently and it may not be possible to bond.On the other hand, heat-sealing at such high temperatures will change the quality of the printed surface, and the toner of the printer may not reach 90℃ or higher. There was a problem that it would melt.

In view of these conventional problems, it is an object of the present invention to provide a completely new secret postcard that has no restrictions on printing and printing and can be created easily and reliably.

Another object of the present invention is to provide continuous postcard paper that allows the secret postcards to be easily and automatically created.

(Means for Solving the Problems) Therefore, the postcard according to the present invention is a postcard in which predetermined matters can be secretly sent by folding postcard paper and pasting the folded sides, A removable low-temperature adhesive heat sealing agent is applied to the overlapping surface, a printed surface and/or a printer printed surface is formed on the heat sealing agent coating layer, and the overlapping surface is releasably pasted by heat sealing. The printed surface and/or printer printed surface is adhered with a peel strength equal to or greater than that of the overlapping surface opposite to the side on which it was formed."

Further, the postcard according to the present invention is a postcard in which predetermined information can be secretly sent by folding postcard paper and pasting the overlapped sides, wherein the printed side is on the overlapped side of the postcard paper. Gard varnish is applied to the printed surface and its surroundings as necessary, and a removable low-temperature adhesive heat sealing agent is applied.
If necessary, printer printing is performed on the heat-sealing agent coating layer, and the overlapping surfaces are releasably attached by heat-sealing."

Here, the ways to fold the postcard paper are two-fold, three-fold,
It may be folded in any way, such as slightly folded.

For example, when folding into three, the postcard paper is folded into three for each width of a normal postcard in the width direction to form the first, second, and third front and back sides, and then the second and third front and back sides are formed. It is desirable that the first back surface and the second N surface be adhered to each other, and that at least the second and third surfaces have the overlapping surface structure according to the present invention.

In addition, in the case of normal folding in two, the postcard paper may be folded in half in the width direction for each width of a normal postcard.

Furthermore, as a modified method of folding in half, the ``slightly folding J'' method divides one side of the same size as a regular postcard into a destination area and a printing area in the longitudinal direction, and one end edge on the printing area side in the longitudinal direction. There is a method in which a postcard paper is integrally provided with a folded piece that covers a print area, and one side of the print area and the folded piece is used as the overlapping surface in the present invention.

Furthermore, instead of peeling off the entire adhered overlapped surfaces from each other, perforations may be made and the sheets may be separated from the perforations and exposed.

In addition, commercially available heat sealants can be used for low-temperature adhesion of the overlapping surfaces. Use a low-temperature adhesion agent with an adhesion temperature of 60 to 80°C, such as 60 to 80°C, that will not damage the print/printed surface during peeling. It is preferable to use it while adjusting the strength.

Furthermore, in order to ensure the adhesion of the overlapping surfaces, a second low temperature adhesive heat sealing agent having a high peel strength may be applied around the entire outer edge of each overlapping surface. The heat sealing agent for low-temperature adhesion is desirably a heat sealing agent that can be pulled and peeled off in an oblique direction so that it can be easily peeled off.

In addition, its peel strength is, for example, 15×1 peel strength is 1
It is desirable that the strength is between 00 and 200 g. Also,
In the case where the adhered overlapping surfaces are separated from the perforations and exposed as described above, the second heat sealing agent may have a very high peeling strength so that it cannot be peeled off.

Furthermore, a printed surface may be formed on one or both of the stacked surfaces except for the entire outer edge thereof, and the peel strength between the printed surface and the outer edge portion may be adjusted to be strong or weak.

Further, it is preferable to cut out a part of the postcard paper, especially a corner of the back surface, in order to facilitate peeling off the pasted overlapping surfaces.

Further, the paper surface other than the overlapping surface may be used as a separate printing surface, or may be used as a printing surface for advertisements or the like.

Further, the continuous postcard paper according to the present invention is characterized in that the above-mentioned postcard paper is made continuous in the longitudinal direction.

Here, each postcard paper may be cut with a cutter or the like, or it may be perforated and then separated.

Further, continuous punch holes for paper feeding may be provided on both sides of the postcard paper so that they can be cut or separated. You can.

(Function) In the present invention, when folding and pasting postcard paper, a removable low-temperature adhesive heat sealing agent is applied, and then printing or printing is done on it and the heat seal is applied. As shown in FIGS. 15(a) and 15(b), a thin layer of heat-sealing agent appears on the printed or printed surface, and the overlapping surfaces are bonded together by both heat-sealing agents, making it possible to peel them off. When applying heat sealant to postcard paper (Fig. 15)
(See C)), the sealant acts more efficiently and printing/
To ensure that the overlapping surfaces of postcard paper are adhered even if the printing layer becomes somewhat thick. Moreover, as the printing and printing surface adheres to the paper surface on which it is formed with a peel strength equal to or higher than that of the overlapping surface of the other party, the printing and printing surface will not be carried away and damaged by the other party when peeled off. This ensures the appearance of the surface. By the way, as shown in Figure 15(d), when applying a similar heat sealing agent to the printed surface and adhering it, the bond between the printed surface and the adhesive is greater than the adhesion between the printed surface and the paper surface. This is compared to the printed surface peeling off in places.

Further, in the present invention, since the postcard paper is folded and pasted with heat seals, it does not require much manpower to create postcards, and automation is easy.

Furthermore, in the present invention, since a heat-sealing agent for low-temperature adhesion is used, there is little risk that the printed/printed layer will be altered by heat during heat-sealing.

Furthermore, in the present invention, when the second heat sealing agent is applied to the outer edge of the stacked surface of the postcard paper, the outer edge of the stacked surface is firmly adhered, and the entire inner surface thereof is weakly bonded in a peelable manner. It will be firmly glued together as a single postcard.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 to 4 show continuous postcard paper for automatic printing according to an embodiment of the present invention. In the figure, ■ is a continuous postcard paper for automatic printing that is usually rolled or folded, and the continuous paper l is a sheet body 2 that can be automatically printed and has a width twice that of a normal postcard. It consists of continuous punch holes 3 for paper feeding provided on both sides of the sheet body 2.

Perforations 40 extending in the width direction are provided in the sheet main body 2 in the longitudinal direction at intervals of the length of a regular postcard so that each unit sheet (postcard paper) 4 can be separated, and the sheet main body 2 and the paper feed A perforation 30 is provided between the continuous punch hole portion 3 and the continuous punch hole portion 3, so that they can be separated from each other.

Further, the sheet main body 2 is folded into three by inserting a folding pattern extending in the longitudinal direction at intervals of the width of an ordinary postcard in the width direction,
This forms first, second and third surfaces 21-23 and back surfaces 24-26, with the first surface 21 being the destination surface and the second and third surfaces 22, 23 being the printing/writing surfaces. On the other hand, the entire first and second back surfaces 24 and 25 are blank surfaces or printing/writing surfaces, and the third back surface 26 is a printing/writing surface.

In addition, each unit sheet 3 on the second and third surfaces 22.23
A second low-temperature adhesive heat sealing agent 5 that peels off with a predetermined peel strength is applied to the entire outer edge of the area, and a second heat sealant 5 that peels off with a predetermined peel strength is applied to the entire inner surface of the second heat seal agent coated area 5 with a peel strength that is less than or equal to the above peel strength. A first heat sealing agent 6 for low-temperature adhesion is coated on the first and second back surfaces 24 and 25, and the second
A heat sealing agent 7 for low-temperature adhesion is applied, and printing/printing is performed on it.

Next, a method for creating a postcard will be explained.

When creating a secret postcard, first apply the prescribed heat sealing agent 5 to 7 on the continuous postcard paper 1 for automatic printing.
is applied in a predetermined manner, and after predetermined printing is performed on it, it is set in a printer device (not shown) of a computer, and the sprocket of the printer device is engaged with the continuous punch hole portion 3 for paper feeding. , While feeding the continuous postcard paper 1 at a predetermined speed, write the address on the first surface 21, and write the address on the second and third surfaces 2.
2. After the notifications, etc. are automatically printed at the same time in step 23, the notifications, etc. are also automatically printed on the first to third back sides 24 to 26 on the back side of the continuous postcard paper, if necessary, using another printer device.

When printing is completed in this way, the continuous postcard paper 1 is sent to a folding machine (not shown), etc., and the second surface 22 and the third surface
Fold the continuous postcard paper l so that the front side 23, the first N side 24, and the second back side 25 overlap, and in that state, heat it at a relatively low temperature, e.g.
After the second surface 22 and the third surface 23 and the first back surface 24 and the second back surface 25 are releasably bonded by heating at 0° C., the paper is fed from the sheet body 2 along the perforations 30. While cutting off the continuous punch hole portion 3, the sheet body 2
When the unit sheets 4 are separated at the perforations 40, a postcard with the addressee, contact information, etc. printed and written and folded into a predetermined shape will be obtained.

In the postcard and continuous paper of this embodiment as described above, the first
The front surface 21 is the destination surface, the second surface 22, the third surface 23 and the third back surface 26 are the printing/writing surfaces.
Since the front surface 23, the first back surface 24, and the second back surface 25 are each removably bonded, the destination surface and the printing/writing surface can be made the same surface, and can be easily used with a relatively popular single-sided computer printer. Automatic printing is easy, and the applications of automatic postcard printing can be greatly expanded.

In addition, in this continuous postcard paper for automatic printing, the first heat sealing agent 5 having a predetermined peel strength is applied to the outer edges of the second surface 22 and the third surface 23, which are the printing/writing surfaces, and the first heat sealing agent 5 having a predetermined peel strength is applied to the inside thereof. The second heat sealing agent 6 was applied to each surface, and the first heat sealing agent 7 was applied to the entire surface of the first N side 24 and second back surface 25, and these were bonded together using a heat sealing machine. , tri-fold postcards can be firmly adhered, a printing/writing area more than twice that of an ordinary postcard can be secured, and the glued printing/writing items are not visible to the outside, so privacy can be protected.

Furthermore, in this continuous postcard paper for automatic printing, heat sealants 5, 6, and 7 are applied to adhere the postcards, so heat sealants 5 to 7 work efficiently and can replace conventional heat-sensitive adhesives. There are no restrictions on printing and writing as with pasting, and the appearance can be improved.As a result, so-called art paper can be used as the material for postcards, and compared to using conventional adhesive stickers. It can be made cheaply.

In addition, in this continuous postcard paper for automatic printing, we used low-temperature adhesives as heat sealants 5 to 7, so there is little risk that the printing/printing layer will change in quality due to heat during heat sealing.・The quality of the printed surface can be guaranteed.

In addition, in this continuous postcard paper for automatic printing, printing is performed after applying the heat sealants 5 to 7, so the heat sealants 5 to 7 pull the printing/printing layer toward the paper side and fix it. However, when the paper surface is peeled off, the printing/printing layer hardly peels off, and the appearance of the printing/printing surface can be ensured.

II Backing ■ Fig. 5 shows a continuous postcard paper for automatic printing according to another embodiment of the present invention. In this embodiment, each unit sheet 4 of the sheet body 2 has a first adhesive on its third surface. A U-shaped perforation 27 is formed at the inner edge of the agent application portion 5, and when each unit sheet 4 is cut and bonded, the second and third surfaces 22
．． The adhesive portion 23 can be separated from the perforation 27 and exposed.

Further, the unit postcard paper 104 is attached to the left edge of the postcard main body 140 having the same dimensions as a normal postcard.
0, and a perforation 144 is formed between the postcard body 140 and the folding piece 141, and the surface of the postcard body 140 is longitudinal. It is divided into a destination area 142 and a print area 143 in the direction.

In addition, each unit postcard paper 104 of the sheet main body 102
A heat sealing agent 105 for low-temperature adhesion that peels off with a predetermined peel strength on the entire surface of the print area 143 and the folded piece 141 on the front side.
is coated.

Regarding the method of creating this postcard, after printing is completed, the continuous postcard paper 101 is folded back with the folding piece 141 facing the printing area 143 using a folding machine (not shown), etc., and in this state, it is heated with a heat sealing machine and folded as described above. The structure is substantially the same as that of the continuous postcard paper for automatic printing of the above embodiment, except that the strip portion 141 and the printing area 143 are releasably bonded, so a detailed explanation thereof will be omitted.

In addition, when viewing the secret information,
] from the postcard body 140 as shown in FIG.
Furthermore, if the folded piece 141 is separated from the postcard main body 140 at the perforations 144 as required, the secret information will appear as shown in FIG.

Also, Figures 11 to 14 show a postcard having twice the paper surface of the present invention, and this is an example of application to a postcard for direct mail. In the figure, 201 is a postcard main body having twice the paper surface of a normal postcard, a folding line 211 is formed in the center of the postcard to enable it to be folded in half, and one half of the postcard main surface 202 has an address writing surface 221, The other half is a printing/writing surface 222, and the entire back surface 203 is an advertisement printing surface 231,232.

A second low-temperature adhesive heat sealing agent layer 204 that adheres with a peel strength of 100 to 200 g at 15×2 is printed and coated on the entire outer edge of the back surface of the postcard body 201 using a predetermined heat seal, and on the inner printed surface. If necessary, after the guard varnish is applied, a first low-temperature adhesive heat seal is applied with a predetermined heat seal to adhere with a peel strength that is weaker than the peel strength of the second heat seal agent layer 204 and does not damage the printed surface when peeled off. A coating layer 205 is applied by printing.

The postcard main body 201 is folded in half along the fold line 211 on the back side, and heat-sealed through a heating roll so that the mating surfaces 231 and 232 are attached to the second heat-sealing agent layer 20.
4 and the first heat sealing agent layer 205.
