Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a postcard with a film that can be used as a postcard.

[Technical day before the invention and its problems]

Conventionally, as shown in FIG. 3, there has been a postcard 21 made of a single layer of paper-like material on which the addressee, sender, etc. are written on the front side and a message written on the back side, and a postcard 21 formed in approximately the same shape as this postcard 21. A film-attached postcard consisting of a transparent film 23 attached to one side edge 27 of the back surface of the postcard 21 has been developed (Utility Model Publication No. 60-25901). The transparent film 23 of this film-attached postcard is made of a transparent base material such as cellophane or polyester that is relatively undeformable by heat, and the postcard side surface of the transparent film 23 is coated with a heat-melting resin 25 such as polyethylene. Coated in layers. To use such a postcard with a film, first write the necessary information on the front and back sides of the postcard 21, and then heat and compress the postcard with a film using a laminating device equipped with a heater and a compression roller. do. Then, the heat-melting resin 25 melts and the transparent film 23 is thermally welded to the back surface of the postcard 21, so that the postcard 21 and the transparent film 23 are brought into close contact with each other. The postcard with the film is then stamped and mailed. In this way, since the back side of the postcard 21 is completely covered with the transparent film, the message written on the back side of the postcard 21 will not be affected even if it gets wet with rainwater or the like.

However, since the postcard 21 made of a single paper-like layer is dried by heating and compressing in a laminating device and is in close contact with the transparent film 23, the postcard 21 absorbs atmospheric moisture after leaving the laminating device. . Then, the transparent film 23 does not expand or contract due to the influence of moisture, whereas the postcard 21 expands as it absorbs moisture, so the entire postcard with film is placed with the transparent film 23 inside as shown in Figure 4. The shape will become severely curved and distorted. In this way, the shape of the postcard with the film is distorted/υ.
There are problems in storage and handling.

[Purpose of the invention]

The present invention has been made in consideration of these points,
To provide a film-attached postcard whose shape does not become distorted when the film-attached postcard is heated and compressed using a laminating device.

[Summary of the invention]

The present invention is a postcard with a film, in which a transparent film in which a layer of hot-melt resin is adhered to one side edge of the inner side of the postcard is pasted, and the inside of the postcard is It is characterized by intervening layers.

According to the present invention, a film layer that is not affected by moisture on elongation is already interposed inside the postcard, so even if moisture is absorbed into the dried postcard that has been heated and compressed by a laminating device, Postcards will not stretch, and those with film will not be distorted due to the locking.

[Embodiments of the invention]

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

FIG. 1 is a perspective view showing an embodiment of a postcard with a film according to the present invention, and FIG. 2 is a side view thereof. In FIGS. 1 and 2, reference numeral 11 is an address sheet, and reference numeral 13 is a correspondence sheet having approximately the same size as the address sheet 11. In FIG.

The address sheet 11 and the correspondence sheet 13 are made of paper or chemical paper. The inner surfaces of the address sheet 11 and the correspondence sheet 13 to be overlapped with each other, or one of the inner surfaces thereof, are coated in advance with a heat-melting resin such as polyethylene or Surlyn (trademark), and the coating is coated on the inside. The postcard 10 is formed by overlapping the address paper-like piece 11 and the correspondence paper-like piece 13, and then subjecting them to heat compression treatment using a laminating device. In this case, the hot-melt resin layer 15 is melted by heating and compression treatment to bring the address paper-like piece 11 and the correspondence paper-like piece 13 into close contact with each other, thereby forming a film layer interposed inside the postcard 10. . Further, a transparent film 17 is pasted on the entire back side edge 12 of the postcard 10 by gluing. This transparent film 17 is made of cellophane,
It is formed from a transparent film material such as polyester that is relatively resistant to thermal deformation. Peel off transparent film 17 1
On the side facing 0, the entire surface is coated with a layer of a heat-melting resin such as polyethylene or Zarlin (trademark). This hot-melt resin 19 is melted by a heat compression process using a laminating device and exhibits an adhesion effect.

To use such a postcard with film, first write the addressee and sender on the front side 10a of the postcard, and write the message on the back side 10b of the postcard. After that, this film-attached postcard is passed through a laminating device (not shown) having a heater and a compression roller, and the heat-compression process is performed so that the transparent film 17 is thermally welded to the back side 10b of the postcard, and the transparent film 17 is bonded to the postcard 10. The film 17 is in close contact with each other. In this way, a postcard with a film, which is constructed by combining the postcard 10 and the transparent film 17 in series, is mailed with a stamp affixed to it.

In this case, a heat-melt resin layer 15 is interposed between the address paper-like piece 11 and the correspondence paper-like piece 13, and this heat-melt resin layer 15 does not absorb moisture and stretch. Even if the address sheet 11 and the correspondence sheet 13 absorb moisture, the meltable resin layer 15 prevents the postcard 10 from stretching. Therefore, even if moisture is absorbed into the postcard 10 that has been heat-compressed and dried by the laminating device, the postcard 1
Since 0 does not stretch, the shape of the postcard with film will not be distorted/v.

In this embodiment, an example of the heat-melting resin layer 15 is shown as a film layer interposed inside the postcard 10, but between the address paper-like piece 11 and the correspondence paper-like piece 13, both sides are heat-melted. Alternatively, a film layer may be provided by sandwiching a transparent film body coated with a transparent resin and not subject to thermal deformation, and subjecting it to heating and compression treatment. In addition, an example was shown in which the transparent film 17 was pasted on the side edge 12 of the back side of the postcard 10 by gluing, but the transparent film 17 was partially pasted (printed) on the side edge 12 of the back side of the postcard 10. It may also be attached by

〔Effect of the invention〕

According to the present invention, a film layer that is unaffected by moisture on stretching is already interposed inside the postcard, so even if moisture is absorbed into the postcard that has been heat-compressed and dried by a laminating device, the postcard will stretch. Without a doubt,
The shape of the entire postcard with film will not be distorted.
