[0002]

2. Description of the Related Art A method of packaging a case accommodating a cassette tape, which is an example of the above-mentioned solid body, is generally described, for example, as shown in FIGS. The cassette tape is packaged from a packaging film 2 for packaging the outer surface of the cassette tape 1 in close contact, and a single narrow film 20 for pulling operation for separating and peeling the packaging film 2. Therefore, the packaging film 2 is peeled off while being separated by pulling the narrow film 20.

However, according to the above method, when the narrow film 20 is pulled, the packaging film 2
Is peeled off while being divided into two parts. In many cases, the narrow film 20 is stuck to one of the two parts of the packaging film 2, and in this state, the narrow film 2 is further removed.
When a pull operation is performed on 0, only one of the divided packaging films 2A (hereinafter, referred to as a first divided packaging film) can be peeled off, but the other divided packaging film 2B (hereinafter, referred to as a second divided packaging film). May be left on the outer surface of the case 1, so that the remaining second
The divided packaging film 2B must be peeled off. However, since there is no pulling portion for peeling off the second divided packaging film 2B, in order to peel off the second divided packaging film 2B stuck to the outer surface of the case 1, the second divided packaging film 2B and the case The second divided packaging film 2B must be peeled by inserting a nail between the outer surface of the second divided packaging film 2B and the second divided packaging film 2B. At this time, the case 1 may be damaged, for example, the outer surface of the case 1 may be scratched by a nail. The reason why the packaging film 2 wrapping the outer surface of the case 1 must be completely removed as described above is to open the case 1 and take out the recording medium in the case.

Unless the narrow film 20 is pulled slowly and carefully, only the narrow film 20 may be peeled off, and both of the two divided packaging films 2A and 2B may remain in the case 1. The above inconvenience was more pronounced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a case 1 for accommodating a cassette tape, which is an example of a solid body, is packaged with a packaging film 2, which is a package. Although the packaging film 2 of the cassette tape is formed into a film based on various kinds of plastics such as polyethylene, polystyrene, and polyvinylidene chloride, the packaging body may be made of a material other than plastic. In addition, depending on the type of the plastic, there are features such as self-adhesion and thermal adhesion, and these may be used. Although the case of mounting on the outer surface of the device will be described, the mounting may be performed by other methods. The present invention can be applied to a case for storing a recording medium such as a cassette tape, a video tape, and a magnetic disk, as well as books, cosmetics, medicines,
Alternatively, the present invention can be applied to a solid body such as a food, a solid body such as a box containing the same, and a box for storing an outer surface of a box storing a solid, liquid, gas, or the like in close contact with each other. In addition, the shape of the solid body, in addition to the rectangular shape in plan view,
Any shape such as a circle, a triangle, a polygon, and a trapezoid may be used.

As shown in FIG. 3, the packaging film 2 has a surface area larger than the surface area of the cassette tape case 1, and one end of the packaging film 2 in the longitudinal direction is formed in a mountain shape. The piece part 3 is formed in a sawtooth shape provided in many side directions. These chevron-shaped pieces 3
Is referred to as a pulling portion 9.
Then, after one package film 2 configured as described above is wound around the cassette tape case 1, both sides are folded as shown in FIG. 2 and the folded state is maintained by heat fusion. . In the figure, by applying heat to the four folds 4, 5, 6, 7
The overlapping portions of the folded portions 4, 5, 6, and 7 are melt-bonded. Thereafter, the winding of the packaging film 2
A part slightly away from the tip of one end
Location, that is, a location 8 slightly away from the chevron-shaped piece 3 (FIG. 1)
Is applied to the portion 8 and the inner surface of the portion 8 by applying heat to the wrapping film 2 .
The other end of the cassette start side, that is, the portion 8 indicated by the dotted line in FIG. 2 is melt-bonded, and the step of packaging the cassette tape case 1 with the packaging film 2 ends. The size of the chevron-shaped piece 3 may be other than that shown in the drawings. Further, as shown in FIG. 4D, one end in the longitudinal direction of the packaging film 2 may be formed in a corrugated shape, and the shape of the pulling portion 9 is not limited to these.

By pulling a part of the pulling portion 9, that is, two chevron-shaped pieces 3 in FIG. 1, the portion of the packaging film 2 corresponding to the pulling portion 9 can be peeled off while being separated. Then, the packaging film 2 remaining on the outer surface of the case 1 can be peeled off by pulling the corresponding pulling portion 9.

FIG. 4A shows another form of the pulling portion 9. That is, the cut 1 along the pulling direction
What formed many 0 may be sufficient. Further, as shown in FIG. 4B, a circular cutout 11 may be integrally formed at each base end of the cut 10 along the pulling direction so that the packaging film 2 can be easily separated.

FIG. 4C shows another form of the pulling portion 9. That is, the case where the mountain-shaped piece 3 is provided intermittently in the longitudinal direction of the case 1 is shown.
In the present invention, the pulling portion 9 is provided on the long side of the rectangular shape of the cassette tape case 1 in plan view, but may be provided on the short side. In FIG. 1, eleven chevron-shaped pieces 3 are formed on the long side, but two or three or more chevron-shaped pieces 3 are provided on the long side or the short side, and the pulling portions 9 are provided. May be configured. Even when two mountain-shaped pieces 3 are provided on a part of the long side, it is considered that the pulling portions 9 are continuously provided corresponding to specific locations of the solid body.
Further, the pulling portion 9 may be provided continuously at only one place, or may be provided at a plurality of places. In the case of storing a circular disk or the like, the case is a square in a plan view. In this case, the pulling portion 9 is provided in any one side direction of the square. Further, it may be provided on any part of the long side or short side of the rectangle, or may be provided by providing a pulling portion 9 at a position corresponding to the upper surface or the lower surface of the case 1 of the cassette tape. In the case where is a rectangular parallelepiped, besides providing the pulling portion 9 in the horizontal direction, the pulling portion 9 may be provided in the vertical direction, and in the case of a spherical body, similarly, the pulling portion 9 may be provided at any place along any direction. The pulling portion 9 may be provided anywhere as long as the packaging film 2 can be separated and peeled off.

FIG. 5 shows a case where a plurality of intermittent cuts 12 (two in the drawing) are formed over substantially the entire circumference of the packaging film 2 in the pulling direction. That is, by separating the packaging film 2 along these cuts 12, no matter what pulling operation is performed,
There is an advantage that the packaging film 2 can be reliably peeled off at three places, and the pulling operation force can be reduced.

[0014]

According to the first aspect of the present invention, the solid body can be quickly and easily peeled off by merely providing the pulling portion intermittently at a specific location of the solid body, and the solid body can be peeled off when the solid body is peeled off. It is possible to avoid a decrease in commercial value without damaging the outer surface.
