DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular parallelepiped article package which has an improved openability without using a tear tape (opening tape).

[0002]

2. Description of the Related Art In general, tape cassette storage boxes for audio and video, and boxes for cigarettes and caramels are made of a thin and transparent outer film made of, for example, a polypropylene film on the outside for storing products. It is tightly packed by the body. Since the outer package is packaged in close contact with the box, it is difficult to open the package as it is. Therefore, it has been common practice to integrate an opening tape and open using the opening tape. However, when the opening tape is used, the opening tape can be seen through from the outside, and one end of the opening tape is overlapped, so that the appearance is deteriorated. In addition, the use of the opening tape requires an opening tape and an operation of integrating the tape, resulting in an increase in cost.

[0003] Therefore, without using such an opening tape,
Numerous means have been proposed as good means. For example, as shown in Japanese Utility Model Application Laid-Open No. 4-84166, a plurality of linear perforations that do not reach the edge portions are provided on a seal band on which a film of an exterior body is superimposed.
As disclosed in Japanese Patent Publication No. 70, there is shown a configuration in which an opening start portion combining an unsealed portion and a cut is provided in a part of a seal band on which a film of an exterior body is overlapped to facilitate tearing. However, if a perforation or an unsealed portion is used in the seal band portion where the films are stacked as described above, the process of providing the outer package becomes complicated, and the opening property is not stable.

[0004] Therefore, as a new opening method, it is mentioned that perforations are continuously provided in the center portion of the exterior body. However, with a configuration in which one linear perforation is provided, the exterior body is pushed right and left and expanded. Even if it did, it was difficult to open it. Thus, with a configuration in which two perforations on a straight line were provided, the package could be easily opened when the outer package was pushed right and left. However, in the case of a configuration in which two perforations on a straight line are provided, although opening is facilitated, there is a problem that an accident of unexpectedly opening may occur.

DISCLOSURE OF THE INVENTION The present invention relates to a packaging body in which the opening of an exterior body for packaging a rectangular parallelepiped object is improved.
An object of the present invention is to provide a package that can be opened without using an opening tape, does not complicate a packaging process, and has good opening stability.

[0006]

In order to achieve the above object, a first invention of the present invention is a package in which a rectangular parallelepiped article is packaged by a package having a seal band on which a film is superimposed, wherein the package comprises: A package for a rectangular parallelepiped article having improved openability, characterized in that a plurality of rows of cut lines, each of which has a plurality of cut lines formed in an inclined shape extending outward to each other, are provided on the body.

[0007] A second invention of the present invention is the package for a rectangular parallelepiped article according to the first invention, wherein said cut lines are provided in three or more rows.

According to a third aspect of the present invention, there is provided a rectangular parallelepiped article according to any one of the first and second aspects, wherein a printed layer is provided on the back surface. It is a package.

[0009]

According to the present invention, there is provided a package in which a rectangular parallelepiped article is wrapped by an outer package having a seal band on which films are stacked, and a plurality of cut lines are formed on the outer package. This makes it possible to obtain a package having a simple opening process and a good opening stability with an unsealing stability.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, which is a package A in which the outside of a rectangular parallelepiped object 10 is packaged with an outer package 20 made of a transparent plastic film. The exterior body 20 is sealed by sealing portions 21A and 21B that are folded and sealed on both sides and a sealing band 22, and a plurality of cut lines 25 are provided at the center. Here, as shown in FIG. 2, the cut line 25 has a configuration in which a large number of cut lines 26 extending outward and inclined are continuously provided. The score line 25 may be provided in two or more rows, but is preferably provided in a range of three to five rows.
It is preferable from the viewpoint of openability and stability.

The plastic film is made of polypropylene, polystyrene, polyethylene terephthalate,
A stretched film made of any one of polyvinyl chloride is suitable, and can be adhered by heat shrinking after packaging the object. In addition, by providing a printed layer for display and coloring on the back surface of the plastic film used for the exterior body 20, the advertising effect and the decoration effect can be improved. At the time of opening, as shown in FIG. 3, by pressing both sides of the score line 25 with a finger and moving it to open both sides, the portion of the score line 25 can be cut right and left and opened.

Since a plurality of rows of cut lines 25 are provided, it is also possible to open the seal band 22 along the cut lines 25 by pulling the cut line 25 portion of the sealing band 22 of the exterior body 20.

Here, the cut line 26 of the cut line 25 will be specifically described. When the cuts 26 are described with reference to FIG. 2, the cuts 26 are continuously provided in a pair of configurations that extend diagonally outward by about 20 degrees with respect to the flow direction, and a single cut line 25 is formed. In practice, the above-described cut line 25 is provided in two or more rows. Here, the cut line 26 forming the cut line 25 is provided in the above-mentioned shape and in a symmetrical shape so that the film can be easily opened, there is no gap, and the film can be opened without leaving any cut end of the film in the opened portion. Can be.

By setting the positions of the cuts 26 of the adjacent cut lines 25 at the same position in the flow direction, a band-like gap can be formed in the flow direction. By providing this band-shaped gap, this part serves as a reinforcing part, and at the time of shrinking, the score line is cut,
In addition, sudden disconnection does not occur.

On the other hand, the material of the rectangular parallelepiped may be any material as long as it is a rectangular parallelepiped box made of a tape cassette storage box for MD, audio, video, etc., a cigarette box, caramel, chocolate or the like.
