DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container for storing a micro floppy disk or the like.

[0002]

2. Description of the Related Art For example, when transporting a large number of micro floppy disks (MFDs), it is common to pack a certain number of these MFDs (for example, 50 sheets) in a paper box and handle them in this state. It is. In this case, as a paper box, a box having an existing structure in which a top plate has a flap-shaped lid is widely used.

FIG. 9 shows the appearance of a box that has been used so far.
FIG. 10 is a development view of the same. That is, as shown in FIG. 10, the conventional box has four side plates 101, 102, 103, 104 connected via a fold line.
And the margin pieces 105 and these side plates 101, 102, 1
Top plate flap 10 connected to both edges 03, 104
6, side flaps 107 and 108, bottom plates 109 and 11
0, flaps 111 and 112 for attaching the bottom plate.

[0004] Each of these elements is cut from a single paperboard (cardboard, cardboard, or the like) in a developed and connected state. By attaching to the inside of 101 and further attaching the bottom plates 109 and 110 to the bottom plate attaching flaps 111 and 112 to close the bottom,
It is assembled as a box as shown in FIG. At this time, the top plate flap 106 plays a role as a lid, and is closed by bending the front end portion 106a and inserting it between the side plate 102 and the stored articles.

[0005]

However, the box having the above-described structure is difficult to handle and has low production costs.
I have various problems. For example, regarding the assembly of the box itself, the side plate 101
It is necessary to bond the bottom plates 109 and 110 to the flaps 111 and 112 for attaching the bottom plates 109 and 110 to the bottom plates 109 and 110, and the workability is extremely poor.

When packing the product in a box, the top plate flap 106 and the side flaps 107 and 108 are opened, and after the packing, the flaps 106 and
It is necessary to close 107 and 108 and seal them with cellophane tape or the like, and since the operation is complicated, automation is difficult,
To some extent, they have to rely on the manual work of the workers.

On the other hand, from the viewpoint of manufacturing cost, the unfolded shape of the box is complicated, and a large area of paperboard is required for material removal due to a shape problem. Therefore, the production requires a large amount of paperboard, which not only increases the production cost but also is inconvenient in terms of resource saving.

Accordingly, the present invention has been proposed in view of such conventional circumstances, and provides a storage container which is easy to manufacture, can reduce manufacturing costs, and is advantageous in terms of resource saving. With the goal. A further object of the present invention is to provide a storage container in which product boxing is extremely easy and automation is easy.

[0009]

In order to achieve the above-mentioned object, a storage container according to the present invention has openings at both ends and has at least circumferential positions at opposing positions on each opening end side. A pair of notches having a pair of cutouts formed therein and having at least a pair of locking pieces that can be folded inward and having a bulging portion projecting from the opening end substantially in the center. A lid is provided, and each of the lids is fitted and disposed at each opening end side of the storage cylinder by inserting a part of the peripheral edge into each of the cuts, and a part of the peripheral edge is stored in the storage cylinder. It is designed to be supported by the above-mentioned locking piece which is folded inside the body.

[0010]

The storage cylinder, which is the main body of the storage container of the present invention, has a simple shape (rectangular shape) in which the material can be easily removed, and hardly any useless parts are formed. This is advantageous. Also, the joining at the time of box making is completed at one place, and the assembling is easy.

When packing the product in a box, one of the lids may be removed, and the product may be sequentially stored in the storage cylinder by using the storage cylinder as a guide. Is greatly improved, and work can be easily automated.

On the other hand, regarding the structure of the container, if the height of the bulge provided at the center of the lid is set to be larger than the width of the locking piece, the bulge protrudes slightly from the storage cylinder. And the external force is received by the bulging portion of the lid. Therefore, the lid serves as a cushioning material, ensuring the strength of the container itself and protecting the stored product from external forces.

In the storage container for storing the disk cartridge, if a projection is provided on the inner surface of the lid to support the outer peripheral position of the disk cartridge, an external force is applied only to the outer peripheral portion of the disk cartridge having high strength. That is, no impact or the like is applied to the recording unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a 3.5-inch MFD storage container will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the storage container of this embodiment has a storage cylinder 1 having a substantially rectangular cross section corresponding to the external shape of a 3.5-inch MFD. The storage cylinder 1 includes a pair of lids 2 and 3 attached so as to close both side openings.

In the vicinity of the opening end of the storage cylinder 1, slits 4 are formed in the circumferential direction so as to straddle each ridge line e of the storage cylinder 1. As a result, the opening of the storage cylinder 1 is opened. Locking pieces 5 corresponding to the length of the slit 4 are provided at the four corners of the end.
Is formed. And these locking pieces 5
The storage cylinder 1 is pushed inward, and a portion 5a corresponding to the ridgeline is bent at a substantially right angle to a side opposite to each ridgeline e of the storage cylinder 1.

The configuration of the storage cylinder 1 has been described above. In order to further clarify the structure of the storage cylinder 1, a procedure for manufacturing the storage cylinder 1 will be described. To manufacture the storage cylinder 1 having the above structure, first, as shown in FIG.
Remove the board from the paperboard in the unfolded state. Here, the material of the storage cylinder 1 is not limited to cardboard, cardboard, or other paperboard, but may be plastic, such as polypropylene, vinyl chloride, or polyethylene terephthalate, or a composite material of these plastics. It is possible to use one.

As shown in FIG. 3, the storage cylinder 1 in the unfolded state has the first side plate 11, the second side plate 12, and the third side plate 13 constituting each side surface of the cylindrical body. The split side plate 14 and the split side plate 15 which are continuously provided with a fold line E corresponding to e, and which constitute a fourth side plate by further bonding to the first side plate 11 and the third side plate. Are provided continuously through a fold line E. Therefore, the developed shape of the storage cylinder 1 is a simple rectangle.

Next, a slit 4 perpendicular to the fold line E is formed in the expanded storage cylinder 1 to form a locking piece 5. The slits 4 are provided on the side plates 11,
Holes are formed so as to extend to both sides across the fold line E at a position having a slight distance L from the edges of both ends of the divided side plates 12 and 13 and the divided side plates 14 and 15. Therefore, the distance L
Corresponds to the width of the locking piece 5.

The length of the slit 4 to be bored is arbitrary. However, if the length of the slit 4 is too long, the protrusion of the locking piece 5 on the end face of the storage cylinder 1 becomes too large. It is preferable that the distance w between the slits 4 is set to be substantially equal to or slightly larger than the length of one side of a later-described bulging portion provided on the lids 2 and 3 fitted and arranged on the end faces.

After the slits 4 are formed in this way to form the locking pieces 5, the side plates 11, 12, 13 and the divided side plates 14, 15 in the developed state are formed into a trunk shape, as shown in FIG. An adhesive is applied to the marginal portion 15a of the divided side plate 15 and glued. Thereby, the cylindrical storage cylinder 1 is formed. The joining at the time of finishing into a cylindrical shape may be, of course, the joining by an adhesive as described above, or the joining by an ultrasonic wave or the joining by a high-frequency seal when made of a plastic material.

Finally, as shown in FIG. 5, each of the locking pieces 5 is pushed inward to complete the storage cylinder 1. At this time, in the present example, the locking piece 5 is bent at a right angle to the side opposite to the side plates 11, 12, 13 and the divided side plates 14, 15 at the fold line corresponding to each ridge line e. When the body 1 is viewed from the opening end side, the locking pieces 5 and the side plates 11, 1
A small square is formed by the corners of 2, 13, 14, and 15.

As the bending method of the locking piece 5, various deformations are possible, such as bending at a right angle as described above and pushing in an arc shape.

On the other hand, as shown in FIGS. 6 and 7, the lids 2 and 3 attached to the opening portions at both ends of the storage cylinder 1 are, as shown in FIGS.
A plate body substantially matching the cross-sectional dimension of the storage cylinder 1 is processed by means such as injection molding, vacuum forming of a sheet, or molding by heating, and bulging portions 21 and 31 are integrally formed at the center portion. It is. The material of the lids 2 and 3 may be the same as that of the storage cylinder 1, or another material may be used.

Here, since the shapes of the lids 2 and 3 are the same, the shape will be described below by taking one of the lids 2 as an example.

The bulging portion 21 provided on the lid 2 has a shape corresponding to the shape of the opening of the storage cylinder 1. That is, the bulging portion 21 is shaped so as to fit in the space surrounded by the bent locking piece 5 and the edge of each of the side plates 11, 12, 13, 14, 15. Therefore, a trapezoidal bulging portion having a rectangular bottom surface 21a and a length of one side slightly smaller than the distance w between the slits 4 may be used. Alternatively, it is also possible to form a substantially cross-shaped bulging portion having four corners depressed corresponding to the pressed shape of the locking piece 5.

The depth D of the bulging portion 21 needs to be set larger than the width (L) of the locking piece 5. The reason why the depth D of the bulging portion 21 is set to be larger than the width of the locking piece 5 is as follows. That is, when the storage cylinder 1 is used as a storage container, there is a high possibility that the locking piece 5 folded inward will buckle and be destroyed due to a drop impact or the like. Then, when the lid 2 provided with the bulging portion 21 deeper than the width of the locking piece 5 is attached to the opening end of the storage cylinder 1, as shown in FIG. It becomes a protruding shape. Then, a drop impact or the like is received on the bottom surface 21a, and the bulging portion 21 plays a role of a cushion, thereby protecting the inside and preventing the storage cylinder 1 from being broken.

Further, in the vicinity of the peripheral edge of the lid 2, there is formed a storage item receiving portion 22 protruding on the side opposite to the bulging portion 21. The storage item receiving portion 22 is formed as a ridge having a slight width, and is formed over the entire periphery of the lid 2 in the present example. In addition, this storage object receiving part 22 is a storage object (3.5 inch MF in this example).
When the 3.5-inch MFD is stored in the storage cylinder 1, its periphery is supported by the receiving surface 22 a of the storage item receiving portion 22. .

The lids 2 and 3 have four corners 2a and 3a, respectively.
a is inserted into the slit 4, that is, the locking piece 5 and each side plate 11,
It is attached to the storage cylinder 1 by inserting it between 12, 13, 14, and 15. At this time, the four corners 2a, 3a of the lids 2, 3 are shaped such that the back side is supported by the cut edges of the locking portions 5 of the storage cylinder 1, and the mounting state is very stable.

The storage container having the above-described configuration is used for 3.5.
When storing the inch MFD, one of the lids 2 and 3 is removed, and the locking piece 5 on the removed side is returned to a state before being pushed in. Then, the storage cylinder 1 is opened, and the side plates 11, 12, 1 of the storage cylinder 1 are opened.
3, 14, 15 play the role of a guide, and the MFD can be smoothly stored in the storage cylinder 1 by a simple operation.

At this time, the stored 3.5-inch MFD
As shown in FIG. 8, the outer peripheral portion 6 is formed by a receiving surface 22 a of a stored object receiving portion 22 provided as a ridge on the lid 2.
a will be supported. 3.5 inch MFD6
In the above, the outer peripheral portion 6a has the highest mechanical strength and is located at a position separated from the recording medium (flexible disk) accommodated therein. There is no damage and there is no risk of damaging the recording medium.

Although a specific embodiment to which the present invention is applied has been described above, the present invention is not limited to this embodiment. For example, in the above-described embodiment, the storage cylinder 1 is a rectangular cylinder having a substantially rectangular cross section, but it may be cylindrical. In the above embodiment, the locking piece 5 is connected to the storage cylinder 1.
Are formed at the four corners, but it is also possible to provide them only at two places located on a diagonal line.

[0033]

As is clear from the above description, the storage container of the present invention has a simple structure and can be assembled very easily. In addition, since the developed shape is a simple rectangle, efficient board removal is possible, so that not only the manufacturing cost can be reduced but also resources are saved.

Further, in the storage container of the present invention, the work of packing and taking out the stored objects is simple, and these steps can be easily automated.

In particular, by increasing the height of the bulging portion of the lid attached to the opening at both ends of the storage cylinder and projecting from the storage cylinder, the lid can be used as a cushioning material against impact. Can be prevented, and damage to the container and the stored items can be prevented. Further, when the stored item is MFD, the MFD is attached to the lid.
If a ridge corresponding to the outer peripheral portion is provided, the recording medium will not be damaged.
