Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method, and more particularly, it is an optimal method for forming a writable area on the surface of an article to be packaged.

[0002]

2. Description of the Related Art For example, as shown in FIG. 1, a tape cassette 1 is designed to be stored and stored in a plastic case 2, which is usually packaged with an exterior film (overlap film). Shipped and sold.

After purchasing, the user usually peels off the exterior film and discards it, and the case is usually used simply as a storage case for storing the tape cassette.

However, in some cases, the contents of the case (contents of the tape cassette) can be confirmed from the outside of the case,
I want to comment. In this case, conventionally, a method has been adopted in which an adhesive label for writing is attached and the adhesive label is attached to the surface of the case, or an index card is put in the case.

[0005]

However, these conventional methods tend to be costly because they require an insertion step in addition to the cost of the adhesive label or index card itself, and the adhesive label is peeled off. It has an easy defect. The present invention has been made to solve the above problems.

[0006]

To achieve the above object, the present invention relates to a packaging method for packaging a case (object to be packaged) with an exterior film, in which a writing ink is provided on the surface of the exterior film which is in contact with the case. A layer is provided, and the writable ink layer is transferred to the surface of the object to be packaged in a state where the case is wrapped with the outer film, and after the outer film is peeled from the case, the transfer portion of the writable ink layer remaining on the surface of the case Is used as a writable area.

[0007]

According to the method of the present invention as described above, the writable area can be formed on the surface of the case surely and easily, and the contents of the case can be confirmed by writing in the writable area. Further, according to this method, the conventional adhesive label and index card are unnecessary, so that the cost can be reduced accordingly.

[0008]

Embodiments of the present invention will be described in detail below with reference to the drawings. First, the outline of the method of the present invention will be described with reference to FIGS.

In this example, the present invention is applied to a plastic case 2 for housing a tape cassette 1 as shown in FIG. That is, the case 2 is the object to be packaged according to the present invention, and the surface of the case 2 is entirely covered with the exterior film 3 as shown in FIG. State. The exterior film 3 is printed with characters, pictures, photographs and the like in design, and a cut end 4 is formed on a part of the exterior film 3 as a trigger for peeling off the exterior film.

A writable ink layer 5 formed by printing writable ink is provided on both surfaces of the exterior film 3, that is, the surface in contact with the case 2 as the object to be packaged. The writable ink layer 5 is formed on the inner surface side of the exterior film 3 corresponding to a predetermined writing area forming position on the surface of the case. The exterior film 3 provided with the writable ink layer 5 forms the case. After packaging 2, the writable ink layer 5 is transferred to the surface of the case 2 by applying heat.

The packaged product is shipped as a finished product in the state where the writable ink layer 5 on the exterior film 3 side is thus transferred to the case 2 side, and is sold side by side in a store as usual.

After the user purchases this, the cut end 4 is pinched and the exterior film 3 is peeled off as shown in FIG. 3, and the exterior film 3 is formed on the surface of the case 2 as shown in FIG.
The writable ink layer 5 transferred from is left, and this portion can be used as the writable area 6. That is, FIG.
As shown in FIG. 3, the contents of the tape cassette can be confirmed at a glance from the outside of the case 2 by writing the recorded contents (tunes, etc.) of the tape cassette in the writable area 6 with the pen 7.

FIG. 6 shows a sectional structure of the exterior film 3 used in the present invention. In the figure, 8 is a transparent base film as a base material of the exterior film, and as the material of the base film 8, polypropylene, polyester, polyethylene, vinyl chloride, cellophane, etc. are preferably used.

On the inner surface side of the base film 8,
The writable ink layer 5 is formed via the release layer 9, and the adhesive layer 10 is further formed on the surface of the writable ink layer 5. Further, a normal color ink layer 11 is formed on the inner surface side of the base film 8 excluding the portion where the writable ink layer 5 is formed. The color ink layer 11 is formed by printing characters, pictures, photographs and the like by multicolor printing, and this printing is visible through the transparent base film 8 from the outer surface side.

For the writable ink layer 5, the peeling layer 9, the adhesive layer 10, and the ink layer 11, various inks having acrylic, nitrified, polyamide, urethane, vinyl chloride or the like as a binder are used. .

In particular, as the writable ink for forming the writable ink layer 5, an inorganic filler having a relatively large particle size (for example, calcium carbonate, barium sulfate, mica, silica, glass, alumina, magnesium oxide, etc.) is added to the binder. What is contained at an appropriate ratio is used, and when the ink is in a dry state, it can be written on the surface with a pencil, a water-based pen, an oil-based pen or the like.

Further, the peeling layer 9 bonds the base film 8 and the writable ink layer 5 with a required binding force, and dissolves when heat is applied to lose the binding force, and the base film 8 and the writable ink layer 5 are lost. Is to be peeled off. Further, the adhesive layer 10 has a heat-sensitive adhesive property, that is, it exerts a strong adhesive property by applying heat. As the material contained in the peeling layer 9 and the adhesive layer 10, various existing materials can be selected and used.

Then, as shown in FIG. 7A, the outer surface side of the base film 8 is formed on the portion where the writable ink layer 5 is formed, as shown in FIG. 7A, with the case 2 as the object to be packaged being wrapped by the exterior film 3 on which the respective layers as described above are printed. By applying heat from a heat roller (made of rubber) 12 to the surface of the case 2 via the adhesive layer 10, the writable ink layer 5 is simultaneously adhered to the base film 8 and the writable ink layer 5 in the release layer 9. Of the writable ink layer 5 is lost.
It is in the state of being transferred to the side.

In this state, the package is shipped and sold, and after the user purchases the package, the exterior film 3 is peeled off as shown in FIG. 7B, and the exterior film 3 and the writing ink layer 5 are completely separated from each other in the release layer 9. As a result, the transfer portion of the writable ink layer 5 remains on the surface of the case 2 as shown in FIG. 7C.

The transfer portion of the writing ink layer 5 can be used as the writable area 6. Since the writable area 6 is formed by thermal transfer as described above, it can be scratched with a nail or the like. It does not come off easily and has sufficient durability.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. In the present embodiment, the case in which the tape cassette is stored is shown as the object to be packaged, but the method of the present invention is not limited to this case for storing the tape cassette, and is widely applied to various objects to be packaged by the exterior film. It goes without saying that it is possible.

[0022]

As described above, according to the method of the present invention, a writable area can be reliably and easily formed on the surface of a packaged object,
By writing in the writable area, the contents can be confirmed from the outside of the packaged item. Further, according to the method of the present invention, the conventionally used pressure-sensitive adhesive label or index card is not required, and the cost can be reduced accordingly. Further, in the method of the present invention, the writable ink layer in the state of packaging the article to be packaged with the exterior film is not damaged because it is on the inner surface side of the exterior film, and only when the user peels the exterior film. Since the writable area appears, the quality of the writable area is maintained, and there is an effect that good writability can be provided.
