Description

[Detailed description of the invention] The present invention relates to a disc-shaped recording medium storage container, in which the upper and lower surfaces of the periphery of the hole near the front opening of the disc-shaped recording medium storage container main body are recessed inward to provide a protrusion. By this, when the disk-shaped recording medium placed in the playback device is recovered into the empty storage container body after playing the disk-shaped recording medium, when the empty storage container body is inserted into the playback device, the storage container body To provide a disc-shaped recording medium storage container in which the disc-shaped recording medium can be well collected into the storage container main body without the upper and lower surfaces on the front opening side of the storage container touching each other and blocking the opening. The purpose is to provide.

For example, a storage container such as a video disk, as shown in FIG. 1, consists of a storage container main body 1 and a front lid 2 detachably connected to the main body 1, and is designed to store a disc-shaped recording medium 3 such as a video disk. It's getting old.

This storage container main body 1 has a substantially concave cross section, for example.
It has a cylindrical shape with one end open, as if two members were joined together, and its upper and lower surfaces have a certain thickness to prevent bending. but,
If the thickness of the upper and lower surfaces is thick, the storage container body becomes heavy because the diameter of the disc-shaped recording medium is approximately 25 to 30 cm, and handling of the storage container containing the disc-shaped recording medium becomes troublesome. The workability of inserting the storage container into the playback device is poor, and due to its weight, the storage container may sometimes slip down, which may damage the storage container or the disc-shaped recording medium.

Therefore, if the wall thickness of the upper and lower surfaces of the storage container body is made thinner, the above-mentioned drawbacks can be overcome. If there is only an empty storage container body with the disc-shaped recording medium and front lid removed, the upper and lower surfaces of the storage container main body will bend, and as a result, the opening of the storage container main body will be closed. However, if the opening of the storage container is blocked, even if an empty storage container is inserted into the playback device in an attempt to recover the disc-shaped recording medium after playback, the opening of the storage container will be blocked. Since the pushing and expanding member of the playback device cannot enter the storage container properly and the opening of the storage container body is not pushed and expanded, the disc-shaped recording medium cannot be recovered into the storage container main body.

The present invention eliminates the above drawbacks, and examples thereof will be described below.

FIG. 2 is an explanatory view of the entire disc-shaped recording medium storage container according to the present invention, and FIGS. 3 and 4 are cross-sectional views of the storage container main body.

In the figure, 30 is a cylindrical storage container main body, and this storage container main body 30 is made of, for example, transparent or translucent synthetic resin, and is molded by extrusion molding with the same cross-sectional shape as the storage container main body. It is extruded and cut into a predetermined length.

Reference numeral 31 denotes a rear lid portion that is inserted into the rear end portion of the storage container main body 30 and fixed by, for example, ultrasonic welding. 33 is formed into a substantially arcuate shape so as to serve as a receiving part when it is stored.

34 is a front opening 30' of the storage container main body 30.
This is a front lid that is detachably attached to the front lid 3.
4 is adapted to be released from the locked state from the storage container body 30 by pressing the lock arm 35 of the front lid inward. In addition, 36 is
These are pins provided on both sides of the front lid 34,
37, 37', 38, and 38' are notches formed in the front lid 34.

A front lid 3 is provided on the upper and lower surfaces 39 of the storage container main body 30.
4 pin 36 and notches 37, 37', 38, 3
Holes 40, 41, 41', 4 corresponding to the position 8'
2,42' are formed. These holes are formed at the same time, or before or after the storage container body is extruded from an extrusion mold and cut into a predetermined length. And these holes 40,
After forming holes 41, 41', 42, 42', holes 40
For this, press the vicinity of the hole 40 from the inside,
The upper and lower surface portions near the hole 40 are made to protrude outward to form a protrusion 43. Also, holes 41, 41', 42, 4
Regarding holes 2', the upper and lower surfaces of the end edges of these holes are pressed inward to recess the upper and lower surfaces to form inner protrusions 44, 44', 45, and 45'.

Note that the shape of the holes 40, 41, 41', 42, 42' is, for example, approximately D-shaped for the hole 40,
The holes 41, 41', 42, and 42' have, for example, a substantially rectangular shape.

By providing the inner protrusions on the upper and lower surfaces of the storage container main body on the front opening side as described above, even when the video disc and front lid are removed from the storage container, the upper and lower surfaces of the storage container main body can be The containers stuck together tightly, causing the top and bottom surfaces of the storage container to come into close contact with each other, blocking the opening. Trouble will no longer occur when recovering the video disc after playback. That is, even if the upper and lower surfaces of the container body try to squeeze together, the opening of the container body will not be blocked due to the presence of the protrusion formed inside the upper and lower surfaces. In particular, when trying to reduce the thickness of the upper and lower surfaces of the storage container body in order to make the storage container lighter and to reduce the amount of material used, the flexibility of the upper and lower surfaces of the storage container body decreases. Although the upper and lower surfaces tend to stick to each other, if the inner protrusions of the upper and lower surfaces are provided as in the present invention, the effect will be extremely large. In addition, from the viewpoint of mass production, it is desirable to manufacture the storage container body by extruding it from an extrusion mold and cutting it into a predetermined length. When making the main body, it is not possible to form an inner protrusion during molding. Therefore, the inventor of this invention
On the upper and lower surfaces near the front opening of the storage container body,
Notice that a hole is formed corresponding to the notch in the front cover, and by applying a pressing force to the edge of this hole and recessing this edge inward, the inner protrusion is formed. I discovered that it can be easily configured.

Furthermore, if a raised part 46 is formed on the upper and lower surfaces 39 near the front opening of the storage container main body 30 at the same time as the above-mentioned protruding part or before or after the process, this raised part 46 can prevent the regeneration. When the storage container main body is inserted into the device, the pushing and expanding mechanism of the playback device can easily enter into the storage container main body 30. That is,
Inner protrusions 44, 44', 4 formed on the upper and lower surfaces
5 and 45' mutually help each other, even if the upper and lower surfaces are bent, the front opening of the storage container main body is wide, making it even more effective.

Incidentally, reference numeral 47 denotes a groove formed in the thick portions of both sides of the upper and lower surfaces 39 of the storage container main body. Further, numeral 48 is a concave-convex portion formed on the thin wall portions on both sides of the upper and lower surfaces 39 of the storage container main body, and the bellows effect of the concave-convex portion 48 is Therefore, when the front opening of the storage container main body is pushed open, cracks or the like are prevented from occurring in the storage container main body.

In the above embodiment, the inner protrusion is formed by using the edge of the hole formed in the upper and lower surfaces, but in order to form the inner protrusion in a portion where no hole is formed, It is also possible to simply form the upper and lower surface portions by recessing them.

The number of inner protrusions may be determined by taking into account the size of the storage container body and the thickness of the upper and lower surfaces of the storage container body, that is, the flexibility, for example, approximately 25 to 30 cm.
2 for a video disc storage container with a diameter of
~4 pieces is sufficient.

As described above, in the disc-shaped recording medium storage container according to the present invention, the upper and lower surfaces of the hole periphery near the front opening of the storage container main body of the disc-shaped recording medium storage container are recessed inward, and the upper and lower surfaces of the storage container main body are recessed. Since the inner protrusion is formed at the top and bottom of the container body, even if the upper and lower surfaces of the storage container body are thin and easily bent, the upper and lower surfaces near the front opening of the storage container body can be stored tightly together. The opening of the container body is not blocked; in other words, the inner protrusion serves as a protrusion, and the opening is opened, so that the disc-shaped recording medium can be recovered after it has been reproduced. When an empty storage container body is inserted into the playback device, the pushing and expanding mechanism of the playback device is properly inserted into the front opening of the storage container body, and therefore the front opening of the storage container body is reliably pushed and spread. Therefore, the disk-shaped recording medium can be inserted and retrieved smoothly without damaging the disk-shaped recording medium. Furthermore, the inner protrusion can be formed by recessing the edge of the hole formed in the upper and lower surfaces of the storage container body, for example. It is easy to construct because it is a container body, and the storage container body can be made by extrusion molding, so it can be made at low cost.Furthermore, since the thickness of the upper and lower surfaces of the storage container body can be made thinner, less material is required. As a result, the cost is reduced accordingly, and since the thickness of the upper and lower surfaces is thin, the upper and lower surfaces can be easily recessed, and the inner protrusion can be easily configured.
