BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging sheet for packaging products and the like, a packaging method for the packaging sheet, and a packaging body in which a plurality of recording medium storage cases are packaged with the packaging sheet.

[0002]

2. Description of the Related Art For example, when a plurality of cassette tapes, floppy disks, etc. are sold or transported in a lump, cases in which these recording media are stored are wrapped together in a wrapping sheet.

FIG. 6 shows an example in which five rolls of cassette tape are packaged. Reference numeral 1 denotes a packaging sheet, which is a film sheet having a rectangular shape in a developed state. The packaging sheet 1 is wound around the upper surface 2, the lower surface 3, and the side surface 4a (4b) in a state where five cassette tape cases are arranged side by side, and is bonded on one side surface 4a side. Further, a part of the sheet is folded into the front and rear surfaces to form the caramel seal portion 2 and the sheets are adhered to each other, and the packaging is completed.

Here, for opening the packaging sheet 1, for example, a knob 5 is provided on a part of the end of the sheet that appears on the side surface 4a side.
Are formed. And when opening, this knob 5
Is lifted and the packaging sheet 1 is torn in a circular shape as shown by the broken line in the figure.

[0005]

However, in the case of performing the opening in this manner, when the packaging sheet 1 is torn by using the knob 5 as a clue, it is often not guided well as shown by the broken line. There is a case where the packaging sheet 1 remains around the case due to the tearing of the sheet 5 or the tearing of the sheet 5 only in the middle, which makes it difficult to open the sheet. In this case, the wrapping sheet 1 has to be torn without tearing.

Further, since the knob 5 is small, the visibility is poor, and sometimes it may be difficult to find the knob 5 when opening. Furthermore, the knob 5 often sticks strongly to the surface of the case in which it is packaged, and it may be necessary to rub it strongly with the tip of a toe in order to lift the knob 5.

Due to these circumstances, if it takes time to open the package, it may be too late to use the cassette tape or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to make it extremely easy to open a package.

For this reason, in the packaging sheet for completing the packaging by adhering a predetermined portion when packaging the object to be packaged, the portion to be adhered, which is the opening portion, has a weak adhesive force. Provided packaging sheets.

Further, as a packaging method, after packaging the packaging sheet with respect to the packaging object, the packaging is performed by bonding the bonding portion to be an opening portion so that the bonding strength is weaker than other required bonding portions. Complete.

Further, in this case, bonding is performed with a part of the unsealing label inserted in the unsealing portion serving as the unsealing portion.

As a packaging body of the recording medium storage case, the periphery of one recording medium storage case or the periphery where a plurality of recording medium storage cases are stacked is packaged with a packaging sheet, and the packaging sheet is adhered with a predetermined adhesion. The points are adhered and packaged, and the adhesion point serving as the unsealing section has a weaker adhesive force than other adhesion points.

[0013]

If the unsealed portion is weakly adhered, the packaging sheet can be easily broken by using it as a clue. In particular, when the opening label is inserted in the opening portion, the visibility of the opening portion is improved, and the opening label is pinched and pulled up to further facilitate the opening. Further, since the opening label is only partially adhered and the non-adhesive portion is led out to the outside of the package, there is no need to pinch the opening label.

[0014]

Embodiments of the present invention will be described below with reference to FIGS. In this embodiment, 10 rolls of compact cassette tape are packaged together.

FIG. 3 is a development view of the packaging sheet, and 10 shows the entire packaging sheet. The packaging sheet 10 is a rectangular film sheet, and although not shown, various designs and product descriptions are printed as a product appearance. The wrapping sheet 10 of FIG. 3 is folded in order to wrap 10 rolls of the cassette tape housed in the case together, and the mountain-folded portion is indicated by a broken line in this case, and is also valley-folded. The part to be marked is indicated by a dashed line. Further, the parts (11a to 11f) with stippling are the parts to be adhered at the time of packaging.

In this packaging sheet 10, 12 is an upper surface portion in the packaged state, 13 is a lower surface portion, 14 is a right side surface portion, and 15a and 15b are adhesive portions 11e and 1
This is the part where 1f is bonded and becomes the left side surface. Also, 16
Reference numerals a and 16b are portions which will be the caramel seal portion on the front surface of the package, and 17a and 17b are portions which will be the caramel seal portion on the rear surface of the package.

FIG. 2 shows an opening label 20 that is partially inserted and adhered during packaging, and the packaging sheet 1
Like 0, it is formed of a film sheet. Reference numeral 21 is a knob portion for gripping when opening. The knob portion 21 is provided with an arrow indicating the direction of picking up as a guide for the opening operation and printing of a character such as "OPEN" as a guide used for opening. Reference numeral 22 denotes an adhesive portion, which is inserted and adhered to the front side caramel seal portion (16a, 16b) of the packaging sheet 10 during packaging.

When wrapping with the wrapping sheet 10, the case 10 containing the cassette tapes is arranged side by side and wound from the left side to the upper side, the right side, the lower side, the left side, and the left side. The surface parts 15a and 15b are bonded to the adhesive parts 11e.
Align and bond 1f. Then, as shown in FIG. 4, the caramel seal portion is formed by folding the front surface and the rear surface. Although the rear surface side is not shown in FIG. 4, the caramel seal portions 17a and 17b are entangled with each other on the rear surface side and are normally bonded at the bonding portions 11c and 11d (heat sealing).

On the front side, the lower caramel seal portion 16b is first folded from the state of FIG. 4 to the state of FIG. Here, an adhesive is applied to the back side of the adhesive portion 22 of the unsealing label 20, and the adhesive portion 22 of the unsealing label 20 is the adhesive portion 1 in the caramel seal portion 16b.
Bonded to 1b.

Next, the upper caramel seal portion 16
The a is folded so that the adhesive portion 11a comes into contact with the upper surfaces of the adhesive portion 11b of the caramel seal portion 16b and the adhesive portion 22 of the unsealing label 20. Here, in the packaging sheet 10 of the present embodiment, the adhesive portion 11a of the caramel seal portion 16a is subjected to halftone printing with a film printing surface of about 40%.

The adhesive portion 11a is heat-sealed with the caramel seal portion 16a folded, and the packaging is completed as shown in FIG.
Due to the fact that the caramel seal portion on the front side is bonded to the caramel seal portion on the front side, the adhesive strength is weaker than that of the other adhesive portions.

In such a package, at the time of opening, the user can easily find the part (opening port) which is a clue to the opening by the relatively large opening label 20. Further, since the knob portion 21 of the unsealing label 20 is not adhered, it is easy to lift it. Then, as the unsealing work, the unsealing label 20 may be pinched and pulled up, whereby the packaging sheet 10 is broken. In particular, since the adhesive strength of the portion to which the unsealing label 20 is adhered is weakened, the unsealing label 20 can be easily unsealed by picking it up.

The adhesive portion 11a may be printed by gradually increasing the thickness of the ink layer to be printed, instead of performing the halftone printing, to weaken the adhesive force after the adhesion. .

Although the opening label 20 is used in this embodiment, the front end side of the adhesive portion 11a of the caramel seal portion 16a is further extended to form a non-adhesive portion, and the portion is picked up at the time of opening. May be. Also in this case,
Since the adhesive strength of the adhesive portion 11a is weakened, it can be easily opened.

In addition to the compact cassette packaging, the present invention also includes various magnetic tape cassettes, optical tape cassettes,
It is effectively applied to the packaging of a case of a tape-shaped recording medium such as an open reel tape, or the packaging of a case of a disk-shaped recording medium such as a floppy disk, an optical disk, a magneto-optical disk. Of course, it can be applied to packaging of products / commodities other than recording media. In addition, how to fold the packaging sheet at the time of packaging, the position of the opening, the shape of the label for opening, and the like are set variously according to the shape of the product to which the present invention is applied.

[0026]
