Description

[Detailed Description of the Invention] This invention relates to improvements in packaging for cards such as commuter passes, credit cards, and driver's licenses.

In order to prevent damage such as scratches and stains, the entire card with the display is covered with a transparent synthetic resin sheet made by laminating a film with a low melting point and a film with a high melting point. Commonly used.

However, in the conventional packaging for this type of card, the front, back and outer periphery of the card were fixed and covered by the synthetic resin sheet, so even thin items such as tickets can be stored in this packaging. That was impossible.

This invention was made in view of the above-mentioned circumstances, and it forms a thin article storage part in a part of the card package as described above, thereby making the package convenient to use. The object is to provide a device with a simple structure that does not reduce its damage and stain prevention function.

An embodiment of this invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 and 2 are transparent outer synthetic resin sheets, and these outer synthetic resin sheets 1 and 2 are ionomers that are ethylene-based ion-binding resins, specifically Surlyn (trade name). ), or a low melting point film 1a made of ethylene-ethyl acrylate copolymer resin, etc.
2a and films 1b and 2b made of polyester or the like having a higher melting point than these are laminated together, and the films 1a and 2a, which have a lower melting point, are placed facing each other and their one short side is fused together. be.

Reference numeral 3 indicates a commuter pass, credit card, driver's license, or other card on which a required display has been applied by any means such as printing on paper, handwriting, or magnetic recording. Card 3 between sheets 1 and 2
Outer layer synthetic resin sheets 1 and 2 are sandwiched between the outside of the four sides, leaving portions directly facing each other.

4 is an inner synthetic resin sheet, and the outer synthetic resin sheet 1
, 2, and a film 4a having a lower melting point and a film 4b having a higher melting point made of the same material as the film 4a and 4b are laminated together, and the two films are made to face each other by folding in half with the film 4b having a higher melting point inside. Card 3
It is sandwiched between the back surface and the outer layer sheet 2 facing the back surface.

The inserted synthetic resin sheet 4 has one end surface that coincides with one long side of the card 3, and the other end surface that protrudes from the other long side of the card 3 and coincides with the long sides of both outer layer synthetic resin sheets 1 and 2. will be placed.

The entire thing made like this is combined with both outer layers of resin sheet 1.
, 2 are heated to a temperature at which the films 1ay2a, 4a with a low melting point can be fused from the outside, but the films 1b, 2b, 4b with a high melting point are not fused, and are pressed together.
As shown in the figure, a film 1at2a with a low melting point of the outer synthetic resin sheets 1 and 2 is placed on both sides of the card 3 facing these, and a film 4a with a low melting point of the inner synthetic resin sheet 4.
and the outer synthetic resin sheet 1,
The low melting point films 1a and 2a of the resin film 4 are fused together at the portions where they directly face each other, and the inner parts of the resin film 4 where the low melting point film 4a faces the card 3 are fused together. The fused portion is then solidified by cooling.

In this way, the part of the inner synthetic resin sheet 4 where the film 4b with a high melting point faces the inside is not bonded, and the storage part 5 is formed between these parts, and the end surface of the storage part 5 is attached to the outer resin sheet. Since it matches the long sides of 1 and 2,
A package having an opening 5a on a part of the long side is constructed.

In the present invention, the inserted synthetic resin sheet is not necessarily folded in half, but may be two independent sheets facing each other with the film having a higher melting point on the inside.

Further, the size of the storage section and the side where the storage section opens can be changed as appropriate, and furthermore, both ends of the storage section may be opened at opposite sides of the package.

As explained above, the card package according to the present invention is
The outer layer synthetic resin sheet 1 is made by laminating films la, 2a with a low melting point and films lb, 2b with a higher melting point.
2 are placed facing each other with the low melting point films 1a*2a on the inside, and a card is sandwiched between these low melting point films 1a*2a, and between one of the low melting point films 2a and the card 3. In part, two sheets are placed facing each other with inner synthetic resin sheets 4 laminated with a film 4a with a low melting point and a film 4b with a higher melting point, one side of which is approximately aligned with the outer edge of the outer layer I-. The outer synthetic resin sheets 1 and 2 are sandwiched between them, and the outer surfaces of the card 3 and the inner synthetic resin sheet 4 are fixed, and the opposing surface of the inner synthetic resin sheet 4 and the outer layer sheet are bonded together. One side of the package is made non-adhesive, and at least one side of the package is opened to form a storage section 5 for thin articles.

The present invention is as convenient as the known card packaging bodies of this type, since cards etc. can be inserted between the outer layer sheets as described above and easily heat-fixed near the melting point of the film, which has a low melting point. Also, at the same time as this heat fixing, a storage portion opened on one side is formed.

According to this invention, it is convenient because thin items such as tickets or a small number of banknotes can be placed in the storage section 5 and carried along with the card, and the entire card is made of an outer layer or an inner synthetic resin sheet. Since it is covered and fixed with these, it does not damage the card or impair its dirt prevention function.
Furthermore, compared to conventional products, only the step of inserting the inner synthetic resin sheet between the card and the outer synthetic resin sheet is increased, so manufacturing is relatively simple, material costs are not very high, and the structure is simple. Effects such as simplicity can be obtained.
