DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case used for storing a recording medium such as a tape cassette.

[0002]

2. Description of the Related Art For example, a recording medium requiring strict management, such as a digital video tape cassette, is stored in a highly sealed storage case. When a plurality of storage cases are stacked and carried, the storage cases may be slippery and unstable, and may collapse during transportation and break. However, there is no conventional storage case having a structure for preventing collapse when stacked as described above.

[0003]

As described above, the conventional storage case does not have a structure for preventing collapse when stacked, so that the stacked case cannot be easily transported.

[0004] The present invention has been made in view of such a point,
It is an object of the present invention to realize a structure for preventing a displacement between storage cases when the storage cases are stacked by using a label area provided in the storage case, and to solve the above-described problems.

[0005]

In order to achieve the above object, a storage case according to the present invention is characterized in that a base portion for storing stored objects and a lid portion for opening and closing the base portion are provided through thin hinge portions. The hinge part is formed symmetrically on the base part side and the lid part side with the hinge part sandwiching the hinge part on the formation surface of the hinge part. A concave label area is formed on one surface of the base portion and the lid portion orthogonal to the surface on which the leg portion is formed, and a convex portion corresponding to the label area is formed on the other surface. In a state where a plurality of storage cases are stacked, the label area and the protruding portion are structured to fit together, and the label corresponds to a pull-out direction when the storage case is taken out from a state in which the storage cases are vertically arranged by the legs. At least one end of the area and the convex part It is made of formed a slope shape.

[0006]

As described above, according to the present invention, when a plurality of storage cases are stacked, the concave label areas and the projections are fitted to each other to prevent the storage cases from being shifted from each other. Does not collapse. Further, in the present invention, since at least one end of the label area and the protruding portion is formed in an inclined surface shape, the label area and the protruding portion are caught when the storage case is taken out from a plurality of standing uprights. It can be pulled out smoothly without any trouble.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. In this example, a storage case used for storing a video tape cassette will be described. In the drawing, reference numeral 1 denotes an overall storage case according to the present invention, 2 denotes a case main body, and this case main body 2 is formed of a resin material, and is opened and closed via a base 3 and a thin hinge 4 on the base 3. It has a lid part 5 which is connected rotatably.

In the case body 2, a storage recess 6 for storing the tape cassette C is provided on the inner surface side of the base 3, and a cover 5 corresponding to the storage recess 6 of the base 3 is provided.
A storage recess 7 is also provided on the inner surface of the tape cassette C. The tape cassette C is stored in the storage recess 6 on the base unit 3 side with the lid 5 open, and the lid 5 is closed by closing the lid 5 thereafter. The tape cassette C is stored in a state where the tape cassette C is accommodated between the storage recesses 6 and 7. Elastic holders 8 and 9 made of rubber material are provided at the four corners of the storage recesses 6 and 7, respectively. When the tape cassette is stored, the corners of the tape cassette C are held by the elastic holders 8 and 9. This protects the tape cassette C from external impact.

A pair of left and right projections 10 are provided in the housing recess 6 on the side of the base 3 so as to project therefrom. When the tape cassette C is housed in the housing recess 6, the projections 10 are exposed on the bottom surface of the tape cassette C. By engaging with a hub (not shown in the figure), rattling of the hub is suppressed. Since the tape cassette C cannot be stored in the opposite direction due to the positional relationship between the hub and the projection 10, the design 11 representing the tape cassette is engraved at the center position of the storage recess 6 in the storage case 1 of this embodiment. This is the guidance display of the direction when the tape cassette C is stored.

A groove 12 is formed on the inner surface of the base 3 so as to surround the storage recess 6, and a rubber packing 13 is embedded in the groove 12. A ridge 14 is formed on the inner surface side of the portion 5 so as to surround the storage recess 7. When the lid 5 is closed, the ridge 14 of the lid 5 is , And is press-fitted to the rubber packing 13 to hermetically seal the inside. Further, a concave groove 15 is formed on the inner surface side of the base portion 3 along the outer edge, while a ridge 16 is formed on the inner surface side of the lid body portion 5 correspondingly.
Is closed, the ridge 16 of the lid 5 is fitted into the concave groove 15 on the side of the base 3, whereby the inside of the case body 2 is double-sealed.

In the storage case 1, the first lock portion 5 is locked with respect to the base portion 3 in a closed state.
To third lock mechanisms 17 to 19 are provided. First
The lock mechanism 17 is provided at a central portion in the case body 2, and as shown in FIG. 5, the engaged projection 20 formed on the base 3 side and the lid
And an engaging projection 21 which is formed on the side and engages with the engaged projection 20 in a state where the lid 5 is closed.
When the lid 5 is closed, the engagement between the engaging projection 21 and the engaged projection 20 causes the lid 5 to be lightly locked in a temporarily fixed state.

The second lock mechanism 18 is provided on the left and right sides on the outside of the case body 2, and as shown in FIG. 6, a rotation lock plate 22 formed integrally with the base portion 3, and a lid Engaged projection 2 projecting from the upper surface side of portion 5
3 The rotation lock plate 22 has a hook-shaped cross-section and is rotatable in a direction corresponding to the opening and closing direction of the lid 5 with the thin hinge portion as a fulcrum. The rotation lock plate 22 is rotated so as to cover the lid body portion 5, and the engagement protrusion 2 provided inside the rotation lock plate 22 is provided.
The lid 2 is locked by engaging the projection 2 a with the engaged projection 23 of the lid 5.

The third lock mechanism 19 is disposed at the center between the second lock mechanisms 18 on both the left and right sides and outside corresponding to the first lock mechanism 17, as shown in FIG. As is apparent, a resin-made slide lock plate 25 slidably mounted on a mount 24 formed on the base 3, and an engagement projection 2 provided on the lid 5 side.
6 The slide lock plate 25 is slid in a lateral direction orthogonal to the opening and closing direction of the lid 5.
A cutout 25a is formed on the side. When the lid 5 is closed, the engagement projection 26 of the lid 5 enters the cutout 25a of the slide lock plate 25, and the slide lock plate 25 is slid from this state to cover the engagement projection 26. Thus, the lid 5 is locked.

A locking projection 27 is provided on the lower surface of the end of the slide lock plate 25. In the locked state, the locking projection 27 is formed on the end of the mounting base 24 to be locked. The slide lock plate 25 is held in a state in which the slide lock plate 25 cannot slide in the unlocking direction by being locked by the projection 28, whereby the locked state is reliably maintained. The unlocking operation of the slide lock plate 25 is performed by elastically deforming and lifting the end of the slide lock plate 25, and removing the locking projection 27 from the locked projection 28.

The case main body 2 is securely and firmly locked and held by the first to third locking mechanisms 17 to 19 configured as described above with the lid 5 closed. In other words, when the lid 5 is first closed, the first lock mechanism 17 temporarily stops in this state, so that the subsequent lock operation of the second lock mechanism 18 and the third lock mechanism 19 is smoothly performed. be able to. Since the left and right sides are locked by the second lock mechanism 18 and the central portion is locked by the third lock mechanism 19, the closed state of the lid body part 5 is ensured while the case body 2 is kept airtight. The second lock mechanism 18 is a rotating lock structure,
The lock mechanism 19 has a slide type lock structure, and the second lock mechanism 18 and the third lock mechanism 19
Since the operation directions are different from each other, the second lock mechanism 18 and the third lock mechanism 19 are unlikely to be unlocked at the same time even when a large vibration or impact is applied during transportation or the like. If either one of the lock mechanism 18 and the third lock mechanism 19 maintains the locked state, the lid 5 does not open, so that the tape cassette in the case body 2 is reliably protected. become.

The structure of the other parts of the storage case 1 of the present embodiment will be further described. Reference numerals 29 and 30 denote grip portions formed on the base portion 3 and the lid portion 5, respectively. The lid portion 5 is closed and locked. In this state, the storage case 1 is carried by grasping the grip portions 29 and 30 together. Also, in the storage case 1, the surface on which the thin hinge portion 4 connecting the base portion 3 and the lid portion 5 is formed has a symmetrical shape between the base portion 3 and the lid portion 5 with the hinge portion 4 interposed therebetween. Legs 3a and 5a are formed. The legs 3a and 5a are provided at two locations on the left and right of the storage case, respectively. And this leg 3
a and 5a support the storage case 1 when the storage case 1 is set upright in the closed state as shown in FIG.
Is supported by the legs 3a and 5a, so that it can be stably placed vertically.

At the left and right corners of the case body 2, hook portions 31 for pulling out the storage case 1 in the lateral direction (the direction of arrow a) are provided. That is, the hook portion 31 is formed by the hook concave portion 3 formed corresponding to the base portion 3 and the lid body portion 5, respectively.
1a and 31b are formed by closing the lid 5 in a closed state, and the inner part thereof is formed by being dug deep in a direction perpendicular to the pull-out direction so that a finger can be easily hooked. When taking out the case 1 from a state in which a plurality of cases 1 are vertically arranged, a finger (index finger) is inserted into the hook portion 31 and pulled out in the lateral direction (direction of arrow a).

The front side of the case body 2, that is, the lid 5
A label area 32 is formed on the upper surface side of the case 2 in a concave shape. That is, a label describing the recorded contents of a tape cassette stored in the case body 2 is attached to the label area 32. I have. On the other hand, the case body 2
On the back side of the base member 3, that is, on the lower surface side of the base portion 3, a projection 33 corresponding to the label area 32 is formed. This convex part 3
In this example, reference numeral 3 denotes two convex stripes corresponding to the long sides of the label area 32 as shown in FIG. 3, and a plurality of storage cases 1 are stacked (FIG. 9) or vertically arranged (FIG. 9). 10) has a structure in which the protrusions 33 are fitted into the concave label areas 32 of the lower or adjacent storage cases, thereby preventing the storage cases from shifting.

In this structure, in the storage case 1 of the present embodiment, the ends corresponding to the draw-out direction (the direction of the arrow a) of the storage case in the label area 32, that is, both left and right ends are inclined surfaces 32a. The left and right ends of the projection 33 are also inclined surfaces 33a. For this reason, when taking out one storage case from a state where a plurality of storage cases are set up vertically and stored side by side, the label area 32 and the protrusion 33 can be pulled out smoothly without being caught.

In the above structure, the shape of the convex portion 33 on the back side of the case main body 2 is different from the two convex stripes corresponding to the long side of the label area 32 as shown in FIG. 12, two ridges corresponding to the short sides of the label area 32 or four ridges corresponding to the corners of the label area 32 may be used. Further, in this example, both ends of the label area 32 and the projection 33 are inclined surfaces, but a configuration in which only one end of the label area 32 and the projection 33 is inclined.

Although the embodiment of the present invention has been described with reference to the tape cassette storage case, it goes without saying that the present invention is not limited to the tape cassette storage case but can be widely applied to various storage cases.

[0022]

As is clear from the above description, the present invention
In a state where a plurality of storage cases are stacked, the concave label area and the projection are fitted to each other to prevent the storage cases from being shifted from each other, so that the storage cases do not collapse during transportation. Can be easily transported in a state where they are stacked. Furthermore, in the storage case of the present invention, since the legs are formed on the formation surface of the hinge portion, the storage case can be stably placed in a vertically upright state,
When the storage case is taken out of a state where a plurality of storage cases are set up vertically, at least one end of the label area and the projection corresponding to the drawing direction is formed in an inclined surface, so that the label area and the projection are formed. Since the storage case is not caught, the storage case can be pulled out smoothly, and the effect is exhibited particularly when the heavy storage case is taken out.
