Description

Description: BACKGROUND OF THE INVENTION (Industrial application field) The present invention relates to a postcard and a continuous sheet thereof that allow predetermined items to be easily sent in secret.

(Prior Art) Conventionally, so-called secret postcards, which are capable of secretly sending notice items and the like, have been often used for various notices and communications such as direct mail or bank transfer notices.

This type of conventional postcard has two folds of paper that are twice the size of a normal postcard, or two normal postcards that are superimposed on each other, with a peelable adhesive seal between them. A sheet in which a heat-sealing agent has been preliminarily inserted is folded in two, and the sheet is adhered so that the sheet can be peeled off by a hot roll or the like. There is, for example, one in which a seal is releasably attached on the remaining portion.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional postcard, since an adhesive seal or a sticking seal is used, not only the postcard becomes expensive, but also printing / printing on the back surface of the seal is required. Impossible.

Also, in the above-mentioned conventional postcard, since a sheet into which a heat sealant is inserted is used, for example, when solid printing of various colors is performed on the paper surface and the ink layer film becomes thick, a high temperature of about 180 ° C. If heat sealing is not used, the sealant of the paper will not act sufficiently and may not be bonded.On the other hand, if heat sealing is performed at such a high temperature, the printing surface will deteriorate, and the toner of the printer will melt at 90 ° C or higher. There was a problem that would.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a completely novel secret postcard which can be easily and reliably created without restrictions on printing and printing.

Another object of the present invention is to provide a continuous postcard that can easily and automatically create the secret postcard.

(Means for Solving the Problems) Therefore, a postcard according to the present invention is a postcard that is formed by folding a postcard sheet and pasting the overlapping surface so that predetermined items can be sent in secret. A peelable low-temperature adhesive heat sealant is applied on the surface, and a printing surface and / or a printer print surface is formed on the heat sealant application layer, and the above-mentioned laminated surface is peelably adhered by heat sealing. The gist is that the printing surface and / or the printing surface of the printer are bonded with a peel strength equal to or higher than that of the overlapping surface side facing the side on which the printing surface is formed.

Further, the postcard according to the present invention is a postcard in which a postcard sheet is folded and the overlapped surface is stuck so that a predetermined item can be sent confidentially, and a printing surface is formed on the overlapped surface of the postcard paper. The gist is that a guard varnish is applied on the printing surface and a releasable heat sealant for low-temperature bonding is applied, and the overlapping surface is releasably adhered by heat sealing.

Here, the folding method of the postcard sheet may be any folding method such as folding in two, folding in three, or folding a little.

For example, in the case of folding in three, the postcard is folded in three for each width of the normal postcard in the width direction, and the first,
The second and third front and back surfaces are formed, and the second and third front surfaces and the first and second back surfaces are adhered to each other. At least the second and third front surfaces are overlapped structures according to the present invention. It is desirable that

Further, in the case of normal folding in two, the postcard paper may be folded in two for each width of the normal postcard in the width direction.

Furthermore, as a method of "slightly folding" as a modification of folding in two, one side of the same size as a normal postcard is divided into a destination area and a printing area in the longitudinal direction, and the above-described printing is performed on one end edge on the longitudinal printing area side. There is a method in which a folded sheet portion covering the area is provided integrally to form a postcard sheet, and one surface of the printed area and the folded sheet portion is set as the overlapping surface in the present invention.

Further, instead of peeling the whole of the adhered overlapping surfaces from each other, a perforation may be provided and separated from the perforation to be exposed.

In addition, a commercially available heat sealant for low-temperature bonding on the overlapping surface can be used.Use a bonding agent that does not damage the printing / printing surface at the time of peeling, for example, a low-temperature bonding agent of 60 to 80 ° C. It is preferable to use while adjusting the strength.

Furthermore, in order to ensure the adhesion of the overlapped surface, a second low-temperature bonding heat sealant having a large peel strength may be applied to the entire outer periphery of each of the overlapped surfaces. In this case,
The second heat sealant for low-temperature bonding is desirably a heat sealant that can be pulled and pulled in an oblique direction so as to be easily peeled. The peel strength is, for example, 15 mm ²
It is desirable that the peel strength is 100 to 200 g. Further, in the case where the laminated surface adhered as described above is separated and exposed from the perforations, the second heat sealant may have a very large peeling strength such that it cannot be peeled off.

Further, a printed surface may be formed on one or both of the overlapping surfaces except for the entire periphery of the outer edge, and the peel strength between the printed surface and the outer edge portion may be adjusted in strength.

In addition, it is preferable to cut out a part of the postcard paper, particularly a corner on the back side, in order to facilitate the peeling of the stuck surface.

Also, the paper surface other than the overlapping surface may be a separate printing surface,
Also, it may be used as a printing surface for an advertisement or the like.

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

Here, each postcard paper may be cut by a cutter or the like,
Alternatively, a perforation may be provided and separated.

Also, continuous punch holes for paper feeding may be provided on both sides of the postcard so that they can be cut or cut off. In this case, a perforation may be provided between the two, and cutting with a cutter or the like may be performed. You may.

(Function) In the invention of the present application, when folding and sticking the postcard paper, a peelable low-temperature bonding heat sealant is applied, and printing or printing is performed thereon, and the heat sealant is adhered by heat sealing. Therefore, as shown in FIGS. 15 (a) and 15 (b), the heat sealant emerges thinly on the printed or printed surface, and the superposed surfaces are bonded by both heat sealants, and can be peeled off. The sealant works more efficiently than when a heat-sealant is inserted into postcard paper (see Fig. 15 (c)), and even if the print / print layer becomes somewhat thicker, The overlapping surfaces of the postcards are adhered. Moreover, the printing and printing surfaces adhere to the paper surface on which they are formed with the same or higher peel strength than the mating surface of the mating partner, so that they are not carried away by the mating partner during peeling and are not damaged The appearance of the surface is ensured. By the way, as shown in FIG. 15 (d), when the same heat sealant is applied to the printing surface and bonded, the bonding between the printing surface and the adhesive is larger than the bonding between the printing surface and the paper surface. This is in contrast to the fact that some parts of the printing surface are peeled off.

Further, in the present invention, since the postcard is folded and adhered by heat sealing, the production of the postcard does not require much manpower and automation is easy.

Further, in the present invention, since a low-temperature bonding agent is used as the heat sealing agent, the print / print layer is less likely to be deteriorated by heat during heat sealing.

Furthermore, in the present invention, when the second heat sealant is applied to the outer edge of the stacking surface of the postcard paper,
As a result, the outer edge of the overlapping surface is firmly adhered, and the entire inner surface is weaker and peelably adhered. As a result, it is firmly adhered as a single postcard.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

First Embodiment FIGS. 1 to 4 show a continuous postcard for automatic printing according to an embodiment of the present invention.

A perforation 30 is provided between the continuous punch holes 3 for use and is provided so as to be separated from each other.

Also, the sheet body 2 is folded in three in a longitudinal direction at a width interval of a normal postcard in the width direction, and is folded in three, whereby the first, second and third front surfaces 21 to 23 and the back surfaces 24 to 26 are formed. Is formed, the first surface 21 is a destination surface,
The second and third front surfaces 22 and 23 are printing / writing surfaces, while the entire first and second back surfaces 24 and 25 are blank or printing / writing surfaces.
The third back surface 26 is a printing / writing surface.

A second low-temperature bonding heat sealant 5 that is peeled at a predetermined peel strength is applied to the entire outer periphery of each unit sheet 3 on the second and third surfaces 22 and 23. A first low-temperature bonding heat sealant 6 that is peeled at a strength equal to or less than the above peel strength is applied to the entire inner surface of the agent application section 5,
The second low-temperature bonding heat sealant 7 is applied to the entire surface of the first and second back surfaces 24 and 25, and printing and printing are performed thereon.

 Next, a method of creating a postcard will be described.

When creating a secret postcard, first, a predetermined heat sealant 5 to 5
7 is applied by a predetermined method, a predetermined printing is performed thereon, and then set in a printer device (not shown) of a computer. Then, while feeding the postcard continuous paper 1 at a predetermined speed, the destination is sent to the first surface 21 and the second and third surfaces 2
After the messages are automatically printed on the sheets 2 and 23 at the same time, the messages are automatically printed on the first to third back surfaces 24 to 26 on the back side of the postcard continuous paper 1 by another printer if necessary.

When printing / printing is completed in this way, postcard continuous paper 1
Into a folder (not shown) or the like, and the second surface 22 and the third
The postcard continuous paper 1 is folded so that the front surface 23 and the first back surface 24 and the second back surface 25 overlap each other, and then heated at a relatively low temperature, for example, 60 to 80 ° C. by a heat sealing machine (not shown) in that state. The second surface 22, the third surface 23, and the first back surface
24 and the second back surface 25 are releasably bonded to each other and then perforated.
Continuous punch hole 3 for feeding paper from sheet body 2 along 30
When the sheet body 2 is cut off for each unit sheet 4 at the perforation 40, the address and the message are printed and written, and a postcard folded in a predetermined shape is obtained.

In the postcard and the continuous paper of the present embodiment as described above, the first 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, and the second surface 22 and the third surface Since the front surface 23, the first back surface 24, and the second back surface 25 are respectively releasably bonded, the destination surface and the printing / writing surface can be made the same surface. Automatic printing can be easily performed, and the use of postcard automatic printing can be greatly expanded.

Further, in the postcard continuous paper for automatic printing, the first heat sealant 5 having a predetermined peel strength is provided on the outer edges of the second surface 22 and the third surface 23 which are the printing / writing surfaces, and the inner surface thereof has a low peel strength. The second heat sealant 6 is applied respectively,
The first heat sealing agent 7 is applied to the entire back surface 24 and the second back surface 25, and these are adhered to each other by a heat sealing machine, so that a three-fold postcard can be firmly adhered. More than twice the printing / writing area can be secured, and the printed / written items adhered are not seen outside, so that privacy can be protected.

Furthermore, in the postcard continuous paper for automatic printing, since the heat sealants 5, 6, and 7 are applied to adhere the postcards, the heat sealants 5 to 7 work efficiently, and the conventional heat-sensitive adhesive is used. Printing and writing are not restricted as in the case of inserting, so that the appearance can be improved, and as a result, so-called art paper can be used as a postcard material, and compared with the case where a conventional adhesive seal is used. It can be made cheaply.

Further, in the postcard continuous paper for automatic printing, since a low-temperature bonding agent was used as the heat sealants 5 to 7, there is little possibility that the printing / printing layer is deteriorated by heat during heat sealing. The quality of the printing surface can be guaranteed.

In the continuous postcard for automatic printing, printing and printing are performed after applying heat sealing agents 5 to 7, so that the heat sealing agents 5 to 7 pull the printing / printing layer to the paper surface side and adhere. However, when the paper surface is peeled, the print / print layer hardly peels off, and the appearance of the print / print surface can be secured.

Second Embodiment FIG. 5 shows a postcard continuous sheet for automatic printing according to another embodiment of the present invention. In this embodiment, each unit sheet 4 of the sheet body 2 is provided with a first adhesive application portion 5 on the third surface thereof.
