Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container which is placed on a desk or the like and is preferably used mainly as a pocket for a notebook, a CD-ROM, a writing instrument or the like.

[0002]

2. Description of the Related Art Small items such as notebooks, CD-ROMs, pens, erasers, and clips tend to be scattered on a desk. Conventionally, these items are stored in a drawer or a desk dedicated to a personal computer. When there were no drawers in the room, they were stored in a small case such as a can case placed on the desk.

[0003]

However, since such small articles are of various kinds and many in number, if they are stored in a drawer or a single accessory case, they are scattered in the drawer or accessory case, and when necessary, Unnecessary things cannot be taken out, which is not preferable in terms of organization. Therefore, if a countermeasure is taken by preparing a plurality of accessory boxes, a problem that the use area of the desk is limited and the usability is deteriorated may occur.
In addition, if these accessory boxes are stacked one on top of the other, the stability is deteriorated, and there is a risk of falling.

[0004] On the other hand, there is known an egg container or the like which can be stacked, but it is not intended for use as a small container, and there is no attempt to structurally increase rigidity. When used as an accessory case, its rigidity becomes a problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem.
By adopting a shape that can engage with each other and increase its rigidity structurally, a plurality can be stably stacked up and down, and small items can be suitably arranged without reducing the use area of a desk or the like. The main purpose is to provide a storage container for storing small items.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, the storage container according to the present invention is capable of storing articles therein, and is capable of engaging the upper wall and the lower wall with each other to structurally increase the rigidity. It is characterized in that it is formed into a shape, and a plurality of them are engaged so that they can be stacked up and down. If something like this,
Another storage container can be engaged with and stacked on one storage container, and since the upper and lower walls have high rigidity, even if a plurality of storage containers are stacked, they can be stably placed on a desk or the like. Therefore, small articles can be stored in a plurality of storage containers and separated appropriately without reducing the use area of the desk. Further, since the structural rigidity of the upper and lower walls is high, a material having a low rigidity or a thin material, which has not been considered in the past, can be used as the material, and the effect on the material can be reduced. In addition, when necessary, the storage container can be individually carried instead of a brush case, and the use thereof can be greatly expanded.

In order to facilitate molding and contribute to simplification of manufacturing, it is desirable that the upper wall and the lower wall are formed with uneven portions which can be engaged with each other over substantially the entire surface. . In order to be able to stably place small articles to be stowed inside on the article mounting surface without reducing the size of the unit concave portion and the unit convex portion forming the uneven portion, at least the cross section of the unit concave portion is trapezoidal. Preferably, a flat article mounting surface is formed at the front end of the rear surface of the unit concave portion.

As a specific embodiment for simplifying the production, reducing the number of parts, or improving the convenience of use, a box-shaped upper lid having the upper wall and opening downward, and a lower wall having the lower wall are provided. A lid having a box-like lower lid that opens upward, these lids are rotatably connected to each other by hinges, and the lids are closed by aligning the opening edges of the lids. And the lower lid have the same shape.

In order to ensure that the opening edges of the lids abut against each other and stably maintain the closed state even when a load is applied by stacking or the like, it is necessary to set a position along the opening edges of the lids. It is preferable that a flange is provided. A specific embodiment in which the present invention can effectively use a material having low rigidity and which is difficult to realize with a conventional accessory case is a material using a pulp mold as the material.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. The storage container 1 according to the present embodiment is called a stacking box, and is mainly used to store small items such as an eraser, a stamp, a mechanical pencil, and the like.
As shown in FIG. 4, the upper cover 6 has a rectangular parallelepiped upper lid 6 that opens downward and a lower lid 7 that opens upward.

Each of the upper and lower lids 6 and 7 has the same shape as each other, and each is called a pulp mold and has a substantially square shape in plan view formed by bending and molding a piece of cardboard obtained by compressing pulp. In the present embodiment, the opening edges 61 and 71 are turned upside down, and the corresponding edges of the opening edges 61 and 71 are pivotally connected to each other with the hinge 9 to thereby bring the opening edges 61 and 71 together. It is configured to be openable and closable between a closed state shown in FIG. 1 and an opened state shown in FIG. Each opening edge 61, 71 is provided with a flange 8 so as to protrude outward, and the flange 8 ensures that the opening edges 61, 71 abut against each other even if the upper and lower lids 6, 7 are slightly rattled. I try to touch. Although not shown, each of the lids 6, 7
The magnets that can adhere to each other with a predetermined force and maintain a closed state are provided on the opening edges 61 and 71 facing the hinges.

On the upper wall 2 of the upper lid 6 and the lower wall 3 of the lower lid 7,
The uneven portion 4 is formed over the entire surface to increase the rigidity. The uneven portion 4 includes a unit convex portion 42 and a unit concave portion 41 which are arranged vertically and horizontally adjacent to each other. In this embodiment, the same number (two) of the unit recesses 4 are arranged in one column (one row).
1 and the unit convex portions 42 are alternately arranged. As shown in FIG. 4, the unit protrusion 42 protrudes from the virtual reference planes S1 and S2 along the opposite opening ends of the side walls 62 and 72 so that the cross-sectional area thereof gradually decreases in the opposite opening direction. It is a square pyramid with a truncated pyramid, and its cross section is trapezoidal. The unit concave portion 41 has a shape in which the unit convex portion 42 is turned upside down, and is depressed so that its cross-sectional area gradually decreases from the virtual reference surfaces S1 and S2 toward the opening direction. Thus, like the unit convex portion 42, the cross section is trapezoidal, and the flat article mounting surface 5 is formed at the front end portion of the back surface. The side walls 62 and 72 of each of the lids 6 and 7 are configured to spread outward toward the opening edges 61 and 71, respectively. This is mainly a device for making it easier to remove the mold.

[0013] Immediately above the storage container 1, as shown in FIG. 5, another storage container 1 is engaged with the upper wall 2 and the lower wall 3 so that the unit convex portion 42 is fitted into the unit concave portion 41. Can be stacked together. Therefore, even if a plurality of storage containers 1 are stacked up and down, they can be stably placed on a desk or the like, and a plurality of small objects such as a pencil OBJ shown in FIG. These can be stored in the storage container 1 and suitably separated.

Further, since the uneven portion 4 is formed over the entire surface of the upper and lower walls 2 and 3, the upper and lower walls 2 and 3 have a three-dimensional shape, and the structural rigidity is high. Therefore,
As in the present embodiment, it is possible to use a pulp mold, which is difficult to adopt in a conventional accessory case, and has a low rigidity, but has a low environmental load using recycled paper such as newsprint. In particular, in this embodiment, when the storage containers are stacked, the inclined surfaces forming the four surfaces of the unit concave portion and the unit convex portion come into contact with each other, so that the effect of effectively distributing the load is also exerted.

Further, since the storage containers 1 are merely stacked, it is possible to provide a wide variety of applications, for example, when necessary, one of them can be removed and carried instead of a brush case. In addition, in this embodiment, the cross section of the unit concave portion 41 and the unit convex portion 42 forming the concave and convex portion 4 is trapezoidal, and the flat article mounting surface 5 is formed at the front end of the rear surface of the unit concave portion 41. Therefore, the unit concave portion 41 and the unit convex portion 4
The small articles stored inside can be stably placed on the article placing surface 5 without reducing the size of the second.

Further, since the upper lid 6 and the lower lid 7 have the same shape, even if the storage container 1 is turned upside down, it can be used in exactly the same manner. Not easy to use. Further, the unit concave portions 41 and the unit convex portions 42 having the same shape are alternately arranged vertically and horizontally, and the unit concave portions 41 included in one row (one row) thereof.
Since the number of and the unit convex portions 42 are set to be the same, even if one storage container 1 is rotated 180 degrees so as to be reversed, it can be stacked on another storage container 1. Also from this point, it can contribute to improvement of usability.

The present invention is not limited to the above embodiment, but can be variously modified. For example, it is needless to say that the material is not limited to the pulp mold, and the upper lid and the lower lid need not have the same shape. The shape of the unit concave portion and the unit convex portion constituting the uneven portion may be, for example, a truncated cone shape, and the cross section is not limited to a trapezoidal shape. In addition, the engagement between the upper wall and the lower wall does not need to depend on the concave and convex portions, as long as the upper and lower walls can be engaged with each other and the structural rigidity of the upper and lower walls can be increased. Further, even when the overall shape of the storage container is also a circular shape in plan view or other various shapes, the same effects as in the embodiment can be obtained.

The specific configuration of the other parts is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention.

[0019]

According to the present invention described in detail above, it is possible to stack one storage container by engaging another storage container, and since the upper and lower walls have high rigidity, they can be stably stacked. Can be placed on a desk or the like. Therefore, small articles can be stored in a plurality of storage containers and separated appropriately without reducing the use area of the desk. Also, since the rigidity of the upper and lower walls is high, a material having low rigidity or a thin material can be used depending on the material, and the restriction on the material is reduced. In addition, the use of the storage container can be greatly expanded, for example, the storage container can be carried instead of a brush case.

If the upper wall and the lower wall are formed with the concave and convex portions which can be engaged with each other over substantially the entire surface, molding can be facilitated, which can contribute to simplification of the production. If the cross section of the unit concave portion forming the concave and convex portion is trapezoidal and the flat article mounting surface is formed at the front end of the rear surface of the unit concave portion, the size of the unit concave portion and the unit convex portion It is possible to stably place the small articles to be stored inside on the article mounting surface without making the object fine.

A box-shaped upper lid having the upper wall and opening downward, and a box-shaped lower lid having the lower wall and opening upward, and the lids are hingedly connected to each other. At the same time, if the upper lid and the lower lid have the same shape and the upper lid and the lower lid have the same shape, only one type of lid may be manufactured. Therefore, it is possible to contribute to unification of a mold and a manufacturing process, and it is possible to reduce costs. In addition, even if it is turned upside down, it can be used similarly, and convenience can be improved.

If the flanges are provided along the opening edges of the lids, the opening edges of the lids can be reliably brought into contact with each other at the flanges. It is possible to stably maintain the closed state. An example in which the present invention makes use of the fact that a material having low rigidity can be used, and a material that is difficult to adopt in a conventional accessory case is applied is one using a pulp mold as the material. In such a case, the use of recycled materials can be expanded.
