Then, the back section body 28 is semi-fixedly held at the approximately rectangular location to the bottom 16 by a fastening means 30 which is provided between the internal confronted walls 24-O of the bottom and the supporting piece 28. Thus, this totally openable type housing case can work as a one side openable type housing case, wherein a lid 14 alone is opened, as well. At the same time, a space 35 of a corresponding shape, in which the supporting piece can be arranged, is provided on the external confronted walls 24-O of the lid, and closing between the bottom and the lid is ensured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully deployable storage case in which a bottom, a lid, and a back body are positioned substantially flat and capable of being fully deployed.

[0002]

2. Description of the Related Art A so-called optical disk, which is a recording medium represented by, for example, a CD, a CD-ROM, or a DVD, is usually stored in a storage case and stored, carried, transported, or displayed.

Here, as a storage case of this type, for example, a so-called polyolefin-based synthetic resin material such as polyethylene or polypropylene, which can give flexibility to a molded product, is used recently. Attention has been paid to the environmental protection issue or the PL method, and conventional synthetic resin materials mainly composed of polystyrene,
That is, the transfer of the material from the styrene resin-based material is being performed in recent years.

Such a storage case made of a polyolefin synthetic resin material is different from a general storage case made of a conventional styrene resin material in which a bottom and a lid are rotatably connected by a boss hinge. The basic structure is different, and normally, the characteristic of the polyolefin-based synthetic resin material that allows the molded product to have flexibility is utilized, and, for example, the back body of the back body is inserted through a linear hinge formed by thinning or the like. A bottom and a lid are connected to each side end of the longitudinal direction to form an integral structure.

[0005]

Here, in the general form of the polyolefin-based storage case as described above, in which the bottom and the lid are connected to each longitudinal end of the back body through linear hinges, the bottom is Since the lid is connected to the back body only through the linear hinges, the bottom, the lid and the back body are fully flattened at the same time when the bottom and the lid are opened.

For example, if the storage case is a flat surface such as a table and has a wide mounting space, there is no problem in fully expanding the storage case. In addition, storage of interior items such as optical disks and books on the bottom and lid,
From the viewpoint of workability, it is said that the work under the full deployment of the storage case is preferable for the removal work, particularly the assembling work by a machine or the like at the time of production as a product.

However, even if it is a flat place such as a table, if it is not possible to secure a wide space for ensuring the full deployment of the bottom, lid, and back body, the interior parts cannot be easily removed and stored. Moreover, if the storage case is fully deployed with the bottom held in one hand, for example, with the back body and the open side of the bottom facing the bottom body being fully deployed, gripping becomes unstable due to the back body unfolding. It is also possible that the entire case is accidentally dropped due to weight loss on the lid side of the interior of a book or the like, which causes an imbalance.

Therefore, the full expansion of the full expansion type storage case is
Although the workability at the time of production is improved, it cannot be denied that it may be inconvenient in some cases in terms of usability.

An object of the present invention is to provide a fully expandable storage case which is compatible with both usability and workability during production.

[0010]

In order to achieve this object, in the present invention, attention is paid to the fact that in the case of a single-opening type storage case in which only the lid is opened, the inconvenience can be sufficiently suppressed. The fully-expandable storage case can be used as a single-open type.

That is, according to the present invention, the opposing walls that overlap at the inner and outer positions due to the closure between the bottom and the lid are integrally erected on the opposite sides of the bottom and the lid, which are orthogonal to the linear hinge, respectively. A support piece that overlaps with a bottom-side facing wall in either the inner or outer position at a position substantially perpendicular to the back body with respect to the bottom is provided upright on the back body at the same position as the lid-side facing wall.

Then, the back body is semi-fixedly held at a position substantially perpendicular to the bottom by a locking means provided between the opposing wall on the bottom side and the support piece, so that only the lid is opened. In addition to being able to be used as a storage case, by providing a space with a corresponding shape in which a support piece can be placed on the lid-side facing wall, the closure between the bottom and the lid can be guaranteed.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1 and FIG. 2, a fully expandable storage case 10 according to the present invention has a bottom (back cover) 14 and a lid (front cover) defined at each longitudinal end of a back body 12. 16) The respective linear hinges 18-B, 18-L are formed so that the bottom, the lid, and the back body are located on a substantially flat surface, that is, so-called full deployment is possible.

In the embodiment of the present invention, as the fully developed storage case 10, for example, a CD or a CD-RO is used.
An example is a disk protection case that accommodates a so-called optical disk as a recording medium represented by M or a DVD. As can be seen from FIG. 2, in this fully expandable storage case 10 which is a disk protection case,
A disc tray 22 having a disc holding portion 20 for detachably holding an optical disc is provided, for example, as an integral interior of the bottom 14 and the like, and the inner surface is formed by folding through linear hinges 18-B and 18-L. The bottom 14 and the lid 16 which are closed together to accommodate the disc tray enables the storage of the optical disc in the fully-developable storage case (see FIG. 3).

Reference numeral 23 shown in FIG. 2 is a locking claw for mounting a book or the like in the lid 14.

Further, the fully expandable storage case (disk protection case) 10 of this kind can be embodied as a resin case molded from a synthetic resin material, and as the synthetic resin material, the molded product has flexibility. For example, polyolefin-based polyethylene, polypropylene, and the like that can be used can be exemplified. And as you can see in Figure 1,
The linear hinges 18-B, 18-L are defined and formed linearly along each longitudinal end of the back body 12 as a bendable flexible portion formed by thinning, for example. The bottom 14 and the lid 16 are integrally connected to each of the longitudinal side ends of the back body through the interposition.

By the way, as shown in FIGS. 1 and 2, in this type of fully unfolding type storage case 10, opposing walls 24 that overlap at inner and outer positions by closing the bottom 14 and the lid 16.
I, 24-O are bottom and lid linear hinges 18-B, 1
They are erected integrally on the opposite side, which is orthogonal to 8-L. In this embodiment, the bottom 14 has an inward facing wall.
24-I and outer facing walls 24-O are erected on the lid 16, respectively, and stand on one side, which is the free end of the outer facing walls of the lid and the bottom, added to the back body 12. The closed configuration of the fully expandable storage case 10 is obtained under the sealing by the provided vertical wall 26.

Incidentally, for example, by a locking means (not shown) provided between the inner facing wall 24-I and the outer facing wall 24-O,
The space between the bottom 14 and the lid 16 is held in the closed state.

In the present invention, the support piece 28 that overlaps the inner facing wall 24-I of the bottom at a position substantially perpendicular to the bottom body 12 with respect to the bottom 14 is the outer facing wall 24 of the lid.
-It is erected integrally with the back body at the same position as O, and this support piece is a locking means for the inner facing wall provided on the bottom.
The back body 12 can be held at a position substantially perpendicular to the bottom under the lock of 30 (see FIGS. 3 and 4).

As the locking means 30, a pair of detachable concave portions 32 and convex portions formed on the respective facing surfaces of the bottom inner facing wall 24-I and the lid outer facing wall 24-O, respectively. A combination with the unit 34 can be exemplified.

According to this structure, the inward facing wall 24-I is formed by the fitting engagement between the concave portion 32 and the convex portion 34 which become the locking means 30.
With the support piece 28 being locked to the back body 12, the back body 12 is
It is held, for example, semi-fixedly, in a position substantially perpendicular to In other words, as shown in FIG. 4, only the lid 16 can be opened when the back body 12 is left at a substantially right angle position with respect to the bottom 14, so that the single-open type storage case in the fully expandable storage case 10 can be opened. It can be used as a case.

As described above, if the fully expandable storage case 10 is in the form of a single-open type storage case, it is possible to sufficiently save the mounting space of the storage case with the lid 16 opened. Then, the shape collapses when the lid 16 is opened,
Since it is possible to prevent the weight from being unbalanced and the like, it is possible to open the lid in a hand-held state and to secure a sufficiently high degree of safety when the interior parts such as an optical disk and a book are put in and taken out.

Therefore, according to the present invention, good usability can be sufficiently ensured even with the fully developed storage case 10.

Since the concave portion 32 and the convex portion 34 serving as the locking means 30 are detachable, the locking of the supporting piece 28 with respect to the inner facing wall 24-I of the bottom by releasing the locking means. By the full deployment of the fully expandable storage case 10, that is, the bottom 1
According to the present invention, the full expansion of the 4, lid 16 and back body 12 to be substantially flat can be ensured as usual. That is,
For example, in the work of assembling with a machine or the like during production as a product, the storage case can be fully developed, so that the workability and the productivity can be surely improved.

Therefore, according to the present invention, it is possible to secure the fully expandable storage case 10 which is compatible with both usability and production workability. Further, since it is sufficient to provide the back body 12 at the same row position as the outer facing wall 24-O of the lid with the support piece 28 that can be locked to the inner facing wall 24-I of the bottom, the structure is complicated. Is also reliably prevented.

As shown in FIGS. 1 and 3, in the present invention, a space 35 having a corresponding shape in which the support piece 28 can be arranged is formed, for example, partially in the outer facing wall 24-O of the lid. It is formed by a notch or the like. According to this configuration,
Since the closure between the bottom 14 and the lid 16 is ensured by the intervention of the support piece 28 in this space 35, this ensures that the deterioration of its functionality due to the presence of the support piece is prevented.

Here, as shown in FIG. 1 and FIG.
In the configuration of the present invention, for example, the facing surfaces 36, 37 of the outer facing wall 24-O of the lid and the supporting piece 28 at the time of closing.
However, it has a stepped shape that allows mutual engagement. And, for example, the concave step portion 36a of the outer facing wall 24-O of the lid
By engaging with the convex step portion 37a of the support piece 28, the outward tilting of the support piece 28 when closed can be regulated.

According to such a structure, the tilting of the support piece 28 to the outside when the lid 16 is closed is prevented. That is, the reliability of the engagement of the support piece 28 with the inner facing wall 24-I of the bottom is improved, and thus the safety of the fully expanded storage case 10 when closed is further improved.

Further, in this embodiment, the bottom facing wall is embodied as the inner facing wall 24-I and the lid side facing wall is the outer facing wall 24-O, respectively. Conversely, the bottom-side facing wall may be the outer facing wall and the lid-side facing wall may be the inner facing wall.

Further, in this embodiment, the linear hinge 18
-B, 18-L is embodied as a partially thinned one, but it is sufficient if the bottom 14 and the lid 16 can be connected in an openable and closable manner at each longitudinal end of the back body 12. The resin film portion is not limited to the one formed by thinning, and the resin film portion may be formed and defined as a linear hinge by, for example, integral molding of the resin film.

In the embodiment of the present invention, the full-deployment type storage case 10 is embodied as a disk protection case for an optical disk, and here, the disk tray 22 is used.
The bottom 14 is shown as an example of a structure that is integrated inside,
The present invention is not limited to this.
It may be configured such that it is provided in 14 and a book or the like is provided in the bottom. In addition, here, the disc tray 22 is the bottom 14,
Although illustrated as a separate body from the lid 16, the bottom,
By providing the disc holding portion 20 integrally with at least one of the lids, at least one of the bottom and the lid may also serve as the disc tray.

Further, the disc tray 22 is not limited to the interior integrated with the bottom 14 or the lid 16, and is rotatable, for example, via a boss-shaped hinge, and one side of the rotatable disc tray is used. Alternatively, the disc holding portions 20 may be provided on both sides.

Further, the fully expandable storage case 10 is not limited to the disk protection case, and if the fully expandable storage case is a floppy (registered trademark) disk, video tape,
Alternatively, it can be used as a protection / storage case for other recording media such as cassette tape, and further, for example, storage cases in various fields such as stationery, tools and cosmetics,
Alternatively, it can be sufficiently used and applied to a packaging case.

Needless to say, it is included in the invention.

[0036]

As described above, according to the fully developed storage case according to the present invention, by holding the back body at a position substantially perpendicular to the bottom, it can also be used as a single-open type in which only the lid is opened. . In other words, by adopting the form of a single-opening type storage case, it is possible to save the mounting space, or to secure the safety during use by preventing the collapse of the shape when the lid is opened and the weight imbalance. As a result, it is possible to sufficiently secure good usability even in the fully developed storage case. And
Since the workability of the product as a product and the improvement of the productivity can be surely achieved by the full deployment, a fully deployable storage case which is compatible with both the usability and the production workability is provided by the present invention. Can be secured if

Since it suffices to provide the back body at the same row position as the lid-side facing wall with the support piece that can be locked to the bottom-side facing wall, it is possible to reliably prevent the structure from becoming complicated.

If the locking means is a combination of concave and convex portions, the structure of the removable locking means can be easily simplified.

Further, if the facing surfaces of the lid-side facing wall and the supporting piece when closed are formed in a stepped shape capable of engaging with each other, tilting of the supporting piece to the outside when the lid is closed is prevented. As a result, the reliability of the engagement of the support piece with the opposing wall on the bottom side is improved, which further improves the safety of the fully deployable storage case when closed.
