Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case, for example, a storage case having a structure suitable for storing a magnetic tape cassette or the like.

[0002]

2. Description of the Related Art Conventionally, various storage cases have been used for the purpose of accommodating and organizing various items or protecting the items. One of the storage cases is a storage case 90 as shown in FIG. 9, which is a target of the present invention. The storage case 90 has a structure in which the case body 30 and the lid body 10 are connected to each other via a connecting portion 20 having a width substantially equal to the case height. The storage case 90 having such a configuration is suitable for storing, for example, the magnetic tape cassette 1 or the like. That is, the storage case 90 has a size substantially equal to the size of the magnetic tape cassette 1 and is made compact. On the other hand, when the case is opened, the lid body 10 and the case body are connected to each other at a predetermined position of the connecting portion 20. Since the magnetic tape cassette 1 is opened to be separated by the width, it is suitable for storing and taking out the magnetic tape cassette 1. Conventional storage case 9 shown in FIGS. 9 and 10.
0 will be described. The storage case 90 shown here is used for storing the magnetic tape cassette 1 as described above,
For example, it is made of synthetic resin or other flexible material. In this storage case 90, a portion connecting the back plate 21, the lid body 10 and the case body 30 is formed thin, and the bendable hinge portion 22 is formed.
23, so that the lid 10 is opened as shown in FIG. 9, and the lid 10 is opposed to the case body 30 as shown in FIG. 10 and the magnetic tape cassette 1 is stored compactly. You are able to take.

As shown in FIG. 9, the case body 30 has a rectangular bottom plate 31 and a pair of parallel side walls 32 and 33 vertically extending along the periphery of the bottom plate 31.
And have. The end portions of the side walls 32 and 33 are connected to each other to form a frame for housing the magnetic tape cassette 1. The height of the side walls 32 and 33 is, for example, lower than the thickness of the magnetic tape cassette 1, and a notch 3 is formed at the top of the side walls 32 and 33.
4 are provided so that the magnetic tape cassette 1 housed in the frame can be easily grasped and taken out by hand.

On the other hand, the lid 10 is, as shown in FIG.
A rectangular top plate 11 and side plates 12.1 vertically provided on the surface of the top plate 11 and arranged in a U shape in a plan view.
And 3. The side plates 12 and 13 extend along the side walls 32 and 33 of the case body 30 when the lid body 10 faces the case body 30 as shown in FIG. Along with 21, the magnetic tape cassette 1 housed in the frame is covered.

The height of the side plates 12 and 13 is slightly higher than the thickness of the magnetic tape cassette 1.
In the state where the lid body 10 is opposed to the case body 30 as shown in, the end surface 15 is, for example, the bottom plate 3 of the case body 30.
The inner surface of the edge portion 1 is in contact with or close to the inner surface. As a result, when an external force P in the thickness direction acts on the storage case 90 as shown in FIG. 10, the side plates 12 and 13 resist the external force P so that the top plate 11 and the bottom plate 31 come close to each other. Therefore, the magnetic tape cassette 1 is protected.

[0006]

By the way, the top plate 1 is used.
Of the side plates 12 and 13 vertically installed on one side, one end portion (end portion on the side opposite to the connecting portion) of the pair of side plates 12 extending in parallel to each other is connected to the side plate 13, so that an external force is applied. Even if a force is applied, the wall will not be easily bent and the wall surface will not be inclined. However, since the end portion 14 of the side plate 12 on the opposite side of the side plate 13 is a free end which is an open end portion of the side plate 12, it easily bends when an external force P as described above is applied. The vertical state with respect to the top plate 11 is difficult to maintain, and the inclined state is likely to occur.

From the above, for example, as shown in FIG. 11, when the magnetic tape cassette 1 is housed in the storage case 90, the external force P acting in the thickness direction of the storage case 90 is applied to the connecting portion 20. When applied to the vicinity of the side plate 12, the side plate 12 may be curved by the action of the external force P, and the end face 15 thereof may come off the bottom plate 31. In this case, as shown in FIG. 12 as a sectional view taken along line CC of FIG.
Since the side plate 12 cannot resist the external force P, the top plate 11 of the lid 10 and the bottom plate 31 of the case body 30 are crushed so as to approach each other. This is this storage case 90
Not only the protection function of the hinges 22 and 23 provided on the connecting portion 20 is reduced, but also the back plate 21 of the connecting portion 20 is curved as shown in FIG.
A strong pulling force or a deforming force such as a shearing force acts on them.
When the strong deformation force is repeatedly applied to the hinge portions 22 and 23 in this manner, the hinge portions 22 and 23 that are thinly formed and bendable will eventually break.

The present invention has been made in view of the above circumstances, and its object is to prevent the side plates of the storage case from being easily disengaged from the opposing wall surfaces even when an external force acts on the storage case. Therefore, it is an object of the present invention to provide a storage case which can guarantee the protection function of the storage case and which is excellent in durability without breaking the hinge portion.

[0009]

SUMMARY OF THE INVENTION The above objects of the present invention are as follows.
The case main body and the lid body are openably and closably connected to each other via a connecting portion, and the case body and the lid body are closed to extend in the case thickness direction at a position near the outer periphery of the lid body or the case body. In a storage case provided with a side plate for positioning, a locking piece capable of position regulation is provided so that the end surface of the side wall on the tip end side is located inside the case outer peripheral edge of the wall surface facing the end surface. This can be achieved by the characteristic storage case. In the storage case, the locking piece is formed on either one of the case body and the lid, the locking piece is provided on the connecting portion, and further, the locking piece is A configuration may be adopted in which the side plate is inclined toward the inside of the case when the case is closed.

[0010]

In the storage case of the present invention, since the tip portion of the side plate erected on the lid is locked so as to be sandwiched between the side wall of the case body and the locking piece, The side plate does not bend away from the side wall. Therefore, even if an external force is applied to the storage case in the thickness direction of the case, the side plate erected on the lid does not easily bend, so that the connecting portion is not deformed. The durability can be improved. Further, when the storage case is closed, an inclined surface is provided so as to guide the tip end portion of the locking piece to the inside of the case. Since it is guided to the position, even if the side plate is deformed, the tip portion of the side plate can be reliably locked.

The side plate 12 of No. 0 is sandwiched, and an inclined surface 43 is formed at the tip portion thereof so that the distance from the side wall 33 increases as it goes toward the closing lid 10. As a result, even if the side plate 12 of the lid body 10 is slightly deformed, the tip 14 of the side plate 12 has the inclined surface 43.
Since the side plate 12 is guided by the side plate 12, the side plate 12 is clamped by the locking piece 42 and the side wall 33 so as not to be displaced laterally.

A third embodiment of the present invention is shown in FIG. This storage case 120 is obtained by further changing the shape of the locking piece 42 provided in the storage case 110 of the second embodiment described above, and the other parts have the same configuration. That is, as shown in a cross-sectional view in FIG. 5, the surface 45 of the locking piece 44 provided in the storage case 120 of the present embodiment facing the side wall 33 is closed from the base end side to the tip end side. The lid 10
The distance from the side wall 33 increases as it goes to. As a result, even if the side plate 12 of the lid 10 is slightly deformed, the tip 14 of the side plate 12 is guided by the inclined surface 45, so that the side plate 12 is sandwiched between the locking piece 44 and the side wall 33. It is locked so that it cannot be displaced laterally.

A fourth embodiment according to the present invention is shown in FIG. The storage case 200 includes the side wall 3 of the case body 30.
3, the locking piece 51 for sandwiching the side plate 12 of the lid body 10,
It is vertically installed on the back plate 21 of the connecting portion 20. As a result, when the lid 10 is closed, as shown in FIGS. 7 and 8, the free end 14 portion of the side plate 12 vertically provided on the lid 10 causes the side wall 33 of the case body 30 and the locking piece 51. Even if the external force P acts on the lid body 10, the side plate 12 is curved so that the end face 15 thereof is the bottom plate 3 of the case body 30.
It does not come off from the top.

Therefore, even if the external force P acts on the lid body 10, the side plate 13 resists the external force P between the top plate 11 of the lid body 10 and the bottom plate 31 of the case body 30.
The distance between the bottom plate 31 and the bottom plate 31 does not become narrow, and the back plate 21 of the connecting portion 20 does not curve as shown in FIG. As a result, the back plate 21 of the connecting portion 20 is curved and the connecting portion 20 is bent.
Since a strong pulling force does not act on the hinge portions 22 and 23, the thinly formed hinge portions 22 and 23 do not break.

It is needless to say that the storage case of the present invention is not limited to the above-described embodiment, and various modifications can be made based on the gist of the present invention. For example, in the embodiment described above, the locking piece 41.
All of 42, 44, 51 are rectangular,
It goes without saying that the shape can be changed to another shape such as a trapezoid. Further, in the first to third embodiments described above, the locking pieces 41, 42,
One 44 is provided on the bottom plate 31 in the vicinity of the connecting portion 20, but it is not necessary to be caught by this and the connecting portion 2
