Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box file having a lid piece and having a bottom lid which can be assembled and folded by one touch.

[0002]

2. Description of the Related Art Conventionally, as this type of box file, a front piece, a rear piece, a left side piece, a right side piece, and a bottom lid are folded to form a box body having an upper surface opening, and a handle hole is formed in the rear piece. At the same time, it is known that the bottom lid can be assembled and folded with one touch. And
In the conventional case, the upper lid piece and the locking piece are sequentially connected to the upper side of the rear piece through a fold line, and the upper opening portion is closed by the upper lid piece during storage. I am able to do that.

[0003]

In such a box file, when the internal documents are frequently taken in and out, the upper lid piece is overlapped with the inner surface of the rear piece. The handle hole provided on the rear piece is closed by the upper surface lid piece, which makes it difficult to use the handle hole. Therefore, even if the operator tries to carry the handle hole by hand, it becomes impossible to secure a sufficient clue. Therefore, it becomes a great obstacle when moving a large number of box files between storages in an office for changing the arrangement or transferring them to a warehouse or a library for long-term storage.

In order to solve such a problem, there has been developed one in which a transparent window is formed in a portion of the upper surface cover piece corresponding to the handle hole. However, when such a transparent window is provided, the upper surface is covered by the upper surface cover body. When the box file is stored in a warehouse or an archive for a long time with the opening part closed, dust will enter the box file through the transparent window.
There is a problem that the stored documents are unduly soiled.

[0005] An object of the present invention is to solve such a problem.

[0006]

The present invention takes the following means in order to achieve the above objects. That is, in the box file according to the first invention of the present application, the front piece, the rear piece, the left side piece, the right side piece, and the bottom lid are folded to form a box body having an upper surface opening, and a handle hole is formed in the rear piece. In a box file that can be assembled and folded with one touch,
An upper surface lid piece and a locking piece are successively provided on the upper side of the front piece through fold lines, respectively, and the locking piece closes the handle hole with the upper surface opening portion closed. Set the shape and size of the locking piece so as not to block, and
The length from the upper side of the front piece to the tip of the locking piece is shorter than the length from the upper side to the lower side of the front piece.

In the box file according to the second aspect of the present invention, the front piece, the rear piece, the left side piece, the right side piece, and the bottom lid are folded to form a box body having an upper surface opening, and the box piece is formed at the upper end of the front piece. In the box file that forms the notch and the handle hole at the upper end of the rear piece, and the bottom lid is one-touch assembleable and one-touch foldable, the bottom side of the notch is sequentially and sequentially through the creases. The lid piece, the upper surface lid piece, and the locking piece are continuously provided, and the locking piece does not close the handle hole in a state where the front cover piece and the upper surface lid piece close the notch and the upper surface opening portion. The shape dimension of the locking piece is set as described above, and the length from the lower side of the cutout to the tip of the locking piece is shorter than the length from the lower side of the cutout to the lower side of the front piece. .

In any of the inventions, when it is desired to make the closed state more reliable, a latching tongue that abuts the upper edge of the rear piece in the closed state at the boundary between the upper surface lid piece and the locking piece. It is preferable that the locking piece is provided with an insertion tongue piece that can be inserted into a notch provided on the rear piece.

[0009]

With this structure, the lid piece is provided on the front piece and the handle hole is provided on the rear piece. Therefore, the lid piece should close the handle hole during use or storage. No need to provide a window hole in the lid piece. Therefore, the drawbacks that the handle hole becomes difficult to use during use and dust enters through the window hole during storage are eliminated. Further, since the locking piece is set to have a shape and dimension that does not block the handle hole with the lid piece closed, it is impossible that the handle hole is blocked by the locking piece and cannot be used.

In addition, as in the first invention of the present application, in the box file having no notch in the front piece, the length from the upper side of the front piece to the tip of the locking piece is the length from the upper side to the lower side of the front piece. In a box file having a cutout portion in the front piece as in the second invention of the present application, the length from the lower side of the cutout portion to the tip of the locking piece is measured from the lower side of the cutout portion to the lower side of the front piece. It is shorter than the length. Therefore, in any case, even if the lid piece is folded back and stored on the inner surface side of the front piece, the tip of the locking piece does not strongly interfere with the bottom lid, and the operation of one-touch assembly or one-touch folding of the bottom lid is performed. There is no inhibition.

Further, according to the means of claim 3, in the closed state, the latching tongue provided at the boundary between the upper surface lid piece and the locking piece contacts the upper edge of the rear piece and the locking piece. Since the tongue piece of is inserted into the notch of the rear piece, it is possible to effectively prevent the top lid piece from immersing in the box file, and some load from above acts on the top lid piece. Even in such a case, the closed state can be reliably maintained.

An inverted trapezoidal notch 2A is provided at the upper end of the front piece 2, a front lid piece 8B is provided on a lower side 2B thereof through a fold line E, and an upper surface of the front lid piece 8B is provided at a top edge thereof via a fold line F. The lid piece 8A is also the top lid piece 8
Locking pieces 9 are connected to the upper edge of A via fold lines G, respectively. The locking piece 9 has an insertion tongue piece 9A, which is locked to a notch portion 11 of a rear piece reinforcing member 3A, which will be described later, at its upper edge. The length L1 of the locking piece 9 in the loading / unloading direction is determined by the rear piece 3 described later.
The length L3 from the upper side to the handle hole 10 is shorter than the length L2 from the lower side of the cutout 2A (folding line E) to the tip of the locking piece 9 and the lower side of the cutout 2A (folding line E). ) To the lower side of the front piece 2 is shorter than the length L4. Then, in the boundary portion between the locking piece 9 and the top cover piece 8A,
A pair of hooking tongues 81 are provided which come into contact with the upper edge 31 of the rear piece 3 in the closed state. These locking tongues 81 are formed by cutting and raising a part of the locking pieces 9, and have a form that extends integrally from the upper surface cover piece 8A.

Further, a handle hole 10 is formed on the upper portion of the rear piece 3, and a rear piece reinforcing member 3A is provided on the upper edge of the rear piece 3 via a fold line. When folded so as to overlap the rear piece 3 along the fold line with the rear piece 3, the handle hole 10
A notch portion 11 that has a handle hole 30 that aligns with and that engages the engaging piece projection 9A is formed at a corresponding position. Further, the left side piece reinforcing member 5A is provided on the upper end edge of the left side piece 5 via the folding line, and the glue margin portion 7 is provided on the left end edge of the right side piece 4 via the folding line.

The box body 1 having such a structure is assembled as follows to be a finished product. First, the rear piece reinforcing member 3A,
Bend the left side reinforcing member 5A inward at the fold line parts,
The rear piece 3 and the left side piece 5 are polymerized on the inner surface side and fixed to each other with an adhesive or the like. Next, the bottom lid members 6A, 6B, 6C, 6D are respectively bent inward at the fold line portions, and the glue margin portions 6E, 6
F is bent back at the folding lines H and K and then returned to the original position, and the front piece 2, the rear piece 3, the right side piece 4, the left side piece 5 and the glue margin portion 7 are bent at the respective folding line portions. In the box-shaped state, at the positions where the bottom lid members 6A, 6B, 6C, 6D serve as the bottom lid, the overlapping portion of the bottom lid member 6C and the glue margin portion 6E, the bottom lid member 6D and the glue margin portion 6F are formed. The overlapping portions are fixed to each other with an adhesive or the like, with the margin portions 6E and 6F facing downward.
The bottom cover members 6A and 6B are respectively bottom cover members 6D and 6C.
The adhesive margin portion 7 and the rear piece 3 are fixed to each other with an adhesive or the like in a state of overlapping with the upper side of the box body 1 to complete the box body 1.

The box file (see FIG. 7a) of this embodiment completed in this way is crushed so as to be folded along the folding lines M and N while pushing the bottom lid 6 from the outer side to the inner side. The bottom lid 6 is folded into the box body 1 while increasing the folding angle (see FIG. 7b), and the entire box body 1 is folded with one touch (see FIG. 7c). Conversely, if the folding lines M and N are returned to the box shape while approaching the folding lines M and N at right angles from the folded state, the valley folding state of the folding lines H and K of the bottom lid 6 is eliminated and the bottom lid member 6
A and 6B automatically mesh with each other in a flat shape, the bottom cover 6 is finished in a flat plate shape, and the box body 1 is assembled with one touch.

With the above construction, when using for organizing documents, as shown in FIGS. 2 and 3, the upper surface lid piece 8A and the front surface lid piece 8B (in the case where it is not necessary to distinguish between the two, they will be referred to as lid pieces 8 hereinafter). Is used by folding it into the box 1. And when carrying it, the fingers are put in the handle hole 10 and carried.
Is formed on the front piece 2 having the lid piece 8 and the rear piece 3 on the opposite side, there is no need to provide a window hole in the lid piece 8 unlike the conventional case.
Therefore, unlike the conventional case, dust is prevented from entering the box body 1 through the window hole and contaminating the inside document when it is stored in a warehouse or a library.

When storing documents and the like, the lid piece 8 is pulled out from the inside of the box body 1 as shown in FIGS. 4 and 5, and the locking piece 9 is inserted so that the insertion tongue piece 9A is inserted into the notch 11. The rear piece 3 is inserted and fixed on the inner surface side. Then, the notch 2A of the front piece 2
The front opening is closed by the front lid piece 8B, and the top opening is closed by the top lid piece 8A. In this case, the latching tongue piece 81 provided at the boundary between the upper surface lid piece 8A and the locking piece 9
Will contact the upper edge 31 of the rear piece 3. Even when carrying in this state, the fingers are put in the handle hole 10 and carried, but as described above, the length L1 in the front-rear direction of the locking piece 9 is the rear piece 3.
Since the length L2 from the upper side to the handle hole 10 is shorter than the length L2, the handle hole 10 is not closed by the locking piece 9, and therefore the handle hole 10 can be carried without trouble.

Further, as shown in FIG. 2, even when the lid piece 8 is carried in an open state, the handle hole 10 is provided on the opposite side of the lid piece 8 so that the lid piece 8 can be removed as in the conventional case. It is no longer an obstacle and difficult to use the handle hole 10.

The bottom cover 6 can be assembled and folded with one touch, and the length L3 from the fold line E to the tip of the locking piece 9 is the length L from the fold line E to the lower side of the front piece 2.
Since it is shorter than 4, the tip of the locking piece 9 does not reach the bottom lid 6, and therefore, even when the lid piece 8 is folded into the box body 1, the lid piece 8 and the locking piece 9 are on the inner surface of the front piece 2. Since the one-touch operation of the bottom lid 6 is performed in a state where the bottom lid 6 and the locking piece 9 are overlapped with each other,
One-touch assembly or one-touch folding can be done without disturbing. As a result, the user can immediately use the box file that has been distributed and stored in the folded state by only one-touch operation, and when it is no longer used, immediately fold it up by one-touch operation and put it away. Is possible.

In the above description, the embodiment in which the front piece 2 has the notch 2A for facilitating the taking in and out of the document has been described, but even if the notch 2A is not provided,
If the lid piece 8 is composed of only the upper surface lid piece 8A and the upper surface lid piece 8A and the locking piece 9 are successively connected to the upper side of the front piece 2 via the fold lines F and G, respectively, it is exactly the same as the above-mentioned embodiment. The effect is obtained (the one according to claim 1).

Further, in the above-mentioned embodiment, the locking tongue 81 is provided at the boundary between the upper surface cover piece 8A and the locking piece 9, or the locking tongue piece 9 can be inserted into the notch 11. 9A is described, but the invention according to claim 1 or 2 also includes those without these latching tongue pieces and insertion tongue pieces. However, if such a latching tongue is provided, even if a load acts on the upper surface lid piece from above in the closed state, the upper surface lid piece will not easily plunge into the inside of the box body. In addition, if the insertion tongue of the locking piece can be inserted into the notch of the rear piece, there is also a problem that the upper surface lid piece 8A is easily lifted and opened from the closed state. It is possible to prevent it. The insertion tongue is not necessarily limited to the one protruding beyond the other tip edge portion of the locking piece. For example, the entire tip edge of the locking piece may be made linear, two cutout grooves may be formed near the center thereof, and the space between the cutout grooves may function as an insertion tongue.

[0023]

As described above, in the box file according to the invention described in claim 1 or 2, since the handle hole is provided in the piece on the side opposite to the piece to which the lid piece is attached, the box file has a window as in the conventional product. It is not necessary to provide a hole, and therefore dust can be prevented from entering the box body. Therefore, even when stored in a warehouse or a library for a long time, it is possible to effectively prevent the internal documents from becoming dirty. Further, since the lid piece is not attached to the piece on the handle hole side, the lid piece does not block the handle hole not only when the lid is closed but also when the lid piece is folded inward. Therefore, whether you use it with the lid open or with the lid closed,
It is possible to securely carry the handle hole with your hand.
Therefore, it is possible to surely and easily perform the transfer from the storage to another storage, the transfer from the storage to the desk or the like, or the transportation from the office to the warehouse or the library.

Moreover, since the tip of the locking piece is set to a length that does not reach the bottom lid, the lid piece can be folded so as to overlap only the inner surface of the front piece without affecting the bottom lid. It will be possible. Therefore, since the lid piece is provided on the front side not having the handle hole, one-touch assembly or one-touch folding of the bottom lid is not possible or difficult.

According to the third aspect of the present invention, when a load is applied to the upper surface lid piece from above in the closed state, the upper surface lid piece is sunk into the box body, or the upper surface lid piece is not easy. It can be effectively prevented from rising. Therefore, the effect that the closed state can be reliably maintained is obtained.
