DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIGS.
This is a packaging container for accommodating D and the video tape collectively. Therefore, the outer shape is made to fit a relatively large video tape, and the CD is fixed inside the tape. In this packaging container, FIG.
As shown in FIG. 2, both the front plate (2) and the back plate (3) have side walls (22) rising from three peripheral edges excluding the hinge portion.
-24 and 32-34). These side walls (22 to 24 and 32 to 34) may have a structure in which the ends of the side walls are abutted when the container is closed, or a part or the whole of one side wall is formed inside the other side wall. It may be a structure that enters. In this example, as seen in FIG. 4B, all of the shallow side walls, ie, the side walls (22 to 24) extending from the front plate, fall inside the deeper side walls, ie, the side walls (32 to 34) extending from the back plate. The free ends (21 and 31) of the front plate (2) and the back plate (3) are provided with engaging means for keeping the packaging container closed. 4A and 4B.
And a ridge (25) provided on the side wall (23) of the front plate is provided with a groove (35) provided on the side wall (33) of the back plate.
The engagement is completed.

[0008] The material for manufacturing the packaging container of the present invention can be arbitrarily selected, but polypropylene, which is known as a material whose hinge connection exhibits durability, is the most prominent. Since polypropylene is a plastic excellent in processability, it is advantageous that the entire packaging container is manufactured by injection molding of polypropylene, and the connection between the intermediate plate (1) and the front plate (2) is also hinged.

[0009] Another example of a packaging container according to the present invention is shown in FIG.
There is one for accommodating D or DVD. In this packaging container, the stop piece (5) also has a hook (51), and the stop piece (5) is pushed forward by the engagement of the engagement means,
It is characterized in that it has an action of fixing an article to be packaged similarly to the locking piece (6). The back plate (3) has a CD or D
A peripheral positioning means (8A) and a center engaging means (8B) for fixing the VD are provided.

The case of a conventional disc such as a CD is
The tip of the rising portion of the hub is bent inward, and a slit is radially formed so as to work as a spring. When storing a disc, align the hole in the center of the disc with the hub, push it in, and fix it using the force of the spring. To remove the disc, press the center of the hub to loosen the spring Operation was required. If the force of the radial spring of the hub is too strong, a large force may be applied to the disc when the hub is taken out. On the other hand, if the force is too weak, the fixing may be insufficient.

On the other hand, in the packaging container of the present invention shown in FIGS. 5 to 7, the hub portion merely passes through the hole in the center of the disk and prevents movement in the lateral direction. It is not directly involved in inserting or removing a disc. The fixing is performed by stopping the stopper pieces (5) at both ends of the back plate (3) as described above.
And the hook (51, 61) of the locking piece (6). By opening the cover (2), the stop piece and the locking piece return to their original positions and release the previously fixed disk, so it is necessary to push out the hub as in the conventional case. And the disk can be taken out with one hand. Of course, there is no need to consider the strength of the spring at the hub.

In addition to the above-described embodiment, the packaging container of the present invention can have various aspects.

[0013]

The packaging container of the present invention has a structure in which a back plate corresponding to a box-shaped container body and a front plate corresponding to a lid are connected via an intermediate plate. Is closed, the projection provided on the intermediate plate pushes the locking piece forward, so that the hook of the locking piece fixes the packaged object, and the fixing is performed firmly. When the top plate is opened, the locking piece made of a material having elasticity and flexibility returns to its original shape, and does not hinder the loading and unloading of the packaged object at all. In this way, a packaging container in which the daily articles can be easily taken in and out, and which can be securely fixed is realized.
