Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a storage case for storing and holding a small number of annular discs such as, for example, compact disc records (hereinafter referred to as CD records).

[Prior Art] Conventionally, this type of storage case has been made entirely of synthetic resin and is thin and foldable or can be opened both ways. Its structure consists of a shape-retaining top plate and a bottom plate that are hinged and can be opened on both sides or folded, and a step protrudes from the inside of the top plate to hold a CD record. A decorative paper displaying this was pasted on. In addition, an engaging piece was provided on the inner side of the bottom plate on the side away from the hinge, and the structure was such that a manual or the like could be inserted and sandwiched through the engaging piece.

[The problem that the idea attempts to solve]

With the above structure, due to the dimensional tolerance between the stepped portion and the annular disk, the engagement may be loose and easily come off, or the engagement may not be possible. for that,
The holding and removing operations were troublesome.

In addition, the shape retention properties of the synthetic resin increase the weight, making it difficult to handle. Moreover, it has to be molded according to various sizes, resulting in high costs.

However, the present invention was developed in view of these circumstances, and it is easy to handle the annular disk.
The purpose is to make it easy to manufacture.

[Means to solve the problem]

In order to solve the above problems, the storage case for annular discs according to the present invention includes a thin holding plate made of synthetic resin that has a shape-retaining property and has a circular hole for storing the annular disk, and this holding plate is stacked on the inside. The cover body is made of a paper material and includes a bottom plate portion fixed to the base plate portion, and a front plate portion folded onto the bottom plate portion through a narrow side plate portion on one side of the front plate portion. At the center of the circular hole of the holding plate, a boss portion into which the center hole of the annular disk is fitted, and a support step portion that supports the periphery of the center hole of the annular disk in succession are integrally formed. A plurality of slits are formed in the radial direction in these boss portions and support step portions, and the annular disk is elastically supported within the circular hole by elastic pieces formed by these slits. It is something.

[Effect]

When the peripheral edge of the center hole of the annular disk is placed against the boss and pushed in, the elastic piece contracts along the slit, so that it is held in a floating state by the support step and at the same time, when the boss returns, the elastic piece contracts along the slit. The central hole is held tightly. When the elastic piece is contracted, the boss part contracts and the engagement is released, making it easy to remove.

Further, it can be manufactured by simply fixing the holding plate to the cover body, and the cover member can be cut and prepared according to various sizes.

〔Example〕

Figures 1 to 4 show an embodiment of the storage case according to the present invention, and in this embodiment, a case will be explained in which a CD record (simply referred to as a record) is used as the annular disc.

First, in FIG. 1, the general structure of a storage case, which is designated by the reference numeral 1 as a whole, will be briefly explained. This case 1 is a thin case made of synthetic resin and has a circular hole 3 for accommodating a CD record 2. It is formed through a holding plate 4, a bottom plate part 5a on which this holding plate 4 is placed and fixed, and a pair of fold lines 6a and 6b forming a narrow side plate part 5b on one side edge of the bottom plate part 5a, It has a front plate part 5c that faces and overlaps the part 5a, and a case body 5 formed of a piece of cardboard. Then, on the back surface (upper surface side in the figure) of the front plate portion 5 of the case body 5, an explanatory booklet 7 formed in the form of a book and including photographs, etc., is attached and attached as needed.

Now, a feature is that a holding portion 10 capable of elastically holding the record 2 is formed in the circular hole 3 of the holding plate 4 that holds the CD record 2 described above.

This will be explained in detail with reference to FIGS. 2 to 4. In the figures, reference numeral 11 indicates the center hole 2a of the CD record 2.
Support steps 12 support the peripheral edge slightly above the bottom of the circular hole 3, and 12 is a boss portion that projects upward from the center and into which the center hole 2a of the CD record 2 is fitted. The portion 11 and the boss portion 12 are formed thin and have a hollow interior. A circular hole 12a is formed in the center of the boss portion 12, and this circular hole 1
A plurality of slits 13 are formed in the radial direction from the periphery of the slit 2a, and the ends of the slits 13 extend through the fitting portion 12b of the boss portion 12 to the support step portion 11 side. Further, as is clear from FIG. 4, the fitting portion 12b of the boss portion 12 is formed with a reverse tapered surface whose diameter decreases downward. By means of these slits 13, the
A plurality of first elastic pieces 14 are formed to elastically hold the center hole 2a of the CD record 2 from inside.

On the other hand, a plurality of slits 15 having a substantially U-shape are formed outwardly on the supporting step portion 11 that serves as the base of the first elastic pieces 14, thereby extending the peripheral edge of the record center hole 2a. Second and third elastic pieces 16 and 17 for elastic support are spaced apart from each other. The second and third elastic pieces 16 and 17 are
The narrow width keeps the elasticity low. Second elastic piece 16
A stepped portion 16 is projected upward at the tip of the third elastic piece 17, and a stepped portion 17 is projected downward at the tip of the third elastic piece 17.
a is protruding.

In addition, 18 in the figure is a tongue-shaped hole that is recessed in a series toward the outside at the peripheral edge of the circular hole 3 of this holding plate 4.
This is for holding the peripheral edge of the CD record 2 held in the circular hole 3 by hand when taking it out.

Due to this structure, the circular hole 3 of the retaining plate 4
When a CD record 2 with approximately the same diameter is inserted into the inside, this record 2 will fit into the fitting portion 12b of the boss portion 12.
and is elastically held by each elastic piece 14, 16, 17. To be more specific, when the CD record 2 is inserted with the center hole 2a in contact with the inserting part 12b, the central part 2b where no recording is made comes into contact with the stepped part 16a of the second elastic piece 16 and 2 elastic piece 1
6 is curved downward. In this state, the third elastic piece 17 is positioned horizontally. As a result, CD
In the record 2, the center hole 2a is tightened and held by the fitting part 12b, and at the same time, especially the second elastic piece 1
The elasticity of No. 6 provides a well-balanced buoyancy.

Further, when taking out the CD record 2 in this state, it is preferable to press the first elastic piece 14 in the center hole 2a of the CD record 2 from above to cause it to elastically deform downward and release the tightened holding state. At this time, the first elastic piece 14 of the boss portion 12 is deformed as shown in FIG. 4, while the amount of deformation of the third elastic piece 17 on the side of the support step 11 is restricted by the step 17a. This acts to lift the CD record 2. In addition to this, the second elastic piece 16
acts to elastically return and lift. As a result, the CD record 2 is lifted out of the circular hole 3, so it is better to take out the CD record 2 using the tongue-shaped hole 18.

Therefore, according to such a configuration, the CD record 2 can be easily and reliably housed and held by utilizing its elasticity, and can also be easily taken out, which is a great advantage in terms of handling. Also,
In the case structure described above, the holding plate 4, the cover body 5, the manual 7, etc. are each constructed separately, and the combination of these serves as the case as a whole, so it is necessary to adjust these to an appropriate size. If you prepare them individually as semi-finished products and use them as a case by combining them as necessary,
It has the advantage of being able to easily cope with the increasing number of types of CD records 2 and being superior in terms of versatility.

It goes without saying that the present invention is not limited to the structure of the embodiment described above, and that the shape and structure of each part can be modified and changed as appropriate.

For example, in the holding part 10 that elastically holds the CD record 2 in the circular hole 3 of the holding plate 4, the shape of the boss part 12 and the supporting stepped part 11, the elastic piece 14 formed therein by the slits 13 and 15, 1
Various modifications can be made to the shapes of 6 and 17. In particular, it is possible to implement a structure in which either the second elastic piece 16 or the third elastic piece 17 is arranged.

Further, as shown in FIG. 5, the holding plate 4 may be formed entirely of a thin resin sheet 20 and a charge 21 made of various materials loaded therein. It goes without saying that the surface of the CD record 2 may be protected by applying flocking 22 to the bottom of the circular hole 3 by flossing or the like.

Furthermore, the cover body 5 is not limited to simply being made of cardboard. As shown in FIG. It is a good thing.

Furthermore, the instruction manual 7 attached to this case 1 is not limited to a book-shaped one, and may be folded and assembled as a single sheet. In this case, as shown in FIG. A modification may be considered in which the bag body 25 is attached to the back surface of the front plate portion 5c of the cover body.

Further, the storage case according to the present invention can be used not only for CD records as described in the embodiments, but also for this type of annular disc to exhibit its effects.
