Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging box for containing a packaged item.

[0002]

[Prior art]

 The swinging of the packaging box and the pressure applied from the outside when transporting or moving the packaging box have often caused damage to the package, and various measures have been taken against this. And among them, three measures exist as the main methods.

One is a method of preparing many kinds of boxes in advance according to the size of the packaged product so that the packaged product is filled inside the packaged box. The second is a method of filling various packings into the space that still holds the packaged products. As a result, the packing that fixes the package also functions as a shock absorber that protects the package from external pressure.

The third method is a method of preventing damage to a packaged product by a structure provided in the box. That is, the side plates are multi-layered, and mooring wall pieces facing each other are provided on the top and bottom of the inside of the packaging box. This method is disclosed in Japanese Utility Model Publication No. 50-130532, in which the laminated side plates protect the package from external pressure applied from four sides, and the mooring wall pieces facing each other prevent the package from swinging up and down as much as possible. It works to prevent.

[0005]

[Problems to be solved by the device]

 However, it is difficult to say that any of these methods respond flexibly to changes in the size of packaged products, and in particular, vulnerable aspects in terms of economic efficiency and efficiency cannot be denied.

In order to select a packaging box according to the size of a packaged product and fill the inside of the packaging box each time, it is necessary to prepare various types of boxes and select the boxes to be packed. As for the packing filling method, various packings must be prepared and the amount and type of packing to be packed must be appropriately determined according to the size of the remaining space.

Also in the method according to Japanese Utility Model Publication No. 50-130532 described above, since the position of the mooring wall piece is fixed, the size of the packaged product is limited in advance in order to sufficiently exert the damage preventing function of the box. There must be. Therefore, in order to deal with various sizes of packaged products, it is necessary to prepare several types of packaging boxes in advance, and in that sense, there is a side that is included in the first method.

[0008] In any of the methods, the size of a packaged product that remains in the packaging box after being accommodated is arbitrarily selected, and a cumbersome operation such as selection of a box and selection and filling of packing is involved. I had no choice but to deal with it.

The present invention was developed to solve the above problems. In other words, as long as the amount of the packaged product can be accommodated inside the packaging box, a package of the same size can be used for a packaged product of any size, and a packaging box that does not involve troublesome packaging work is provided. With the goal.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following configuration. That is, an arbitrary number of side plates 1, 2, 3, 4 and an arbitrary number of cover plates 6, 7, 8, 9 connected to the side plates 1, 2, 3, 4 via a tangent side and an arbitrary number. In a packaging box consisting of a number of bottom plates 10, 11, 12, 13 and at least one of the front surface and the back surface of any lid plate, the inner side of the lid plates 7, 9 is folded, and An arbitrary number of folding lines A orthogonal to the opening / closing direction of 7 and 9 were provided at arbitrary intervals.

Here, the length of the side of the lid plates 7 and 9 having the folding line A along the opening / closing direction is set to be 0.5 to 2.5 times the width of the lid plates 7 and 9 in the opening / closing direction. It is suitable. Further, the folding lines A provided on the arbitrary lid plates 7 and 9 may be provided with an arbitrary number of orthogonal breaking lines at arbitrary intervals.

If there is a cover plate facing any number of cover plates provided in the packaging box of the present invention, the cover plates facing each other are also orthogonal to the opening / closing direction of the cover plates. It is preferable to provide a folding line.

When the sides of the lid plates 7 and 9 having the fold line A along the opening and closing direction face each other and the lid plates 6 and 8 are provided on the sides, the two opposite lid plates 6 and 8 are arranged. The sum of the lengths of the sides along the opening / closing direction may be at least equal to the width of the facing lid plates 6 and 8 in the opening / closing direction.

When the cover plates 6 and 8 are provided on the sides of the cover plates 7 and 9 having the folding line A along the opening / closing direction, the lengths of the sides of the cover plates 6 and 8 along the opening / closing direction are The width of the cover plates 6 and 8 in the opening / closing direction may be the same.

[0015]

[Action]

 Description will be made taking as an example a situation in which the function of the packaging box of the present invention is maximized, that is, a case in which a packaged item that has been housed and leaves a space above the inside of the packaged box is housed.

Any number of side plates 1, 2, 3, 4 and any number of cover plates 6, 7, 8, 9 connected to the side plates 1, 2, 3, 4 via a tangent side and any number In a packaging box consisting of a number of bottom plates 10, 11, 12, 13 the present invention applies to at least one of the front and back surfaces of any lid plate 7, 9 inside the lid plate 7, 9 An arbitrary number of folding lines A that are bent at a right angle and are orthogonal to the opening and closing directions of the lid plates 7 and 9 are provided at arbitrary intervals.

Now, the side plates 1, 2, 3, 4 and the bottom plates 10, 11, 12, 13 are assembled and packed in the packaging box of the present invention in a state where the lid plates 6, 7, 8, 9 are opened. Put the product in and try closing the cover plates 6, 7, 8 and 9.

The lid plates 7 and 9 having the folding lines and the side plates 2 and 4 located at the position closest to the tangent side of the side plates 2 and 4 are pivoted about the folding lines of the lid plates 7 and 9 to form the lid plates 7 and 9. Fold it to the required angle toward the inside of the surface. The lid plates 7 and 9 are then folded inside the surfaces of the side plates 2 and 4 which are connected to each other through the edges.

When the lid plates 7 and 9 are folded as they are inside the surfaces of the side plates 2 and 4, the tips of the lid plates 7 and 9 come into contact with the packaged product. When the folding line A is folded so that the height corresponding to the height of the space remaining above the package is left and the lid plates 7 and 9 are closed, the package is pressed by the lid plate. You can

When forming the packaging box of the present invention, the range of the side length in the opening / closing direction of the lid plates 7 and 9 having the fold line A is set to 0. If set in advance so as to be 5 to 2.5 times, the area covering the upper opening of the packaging box does not exist in the lid plates 7 and 9, or conversely, the side of the lid plates 7 and 9 in the opening and closing direction. It is possible to avoid an unnecessary trouble that the cover plates 7 and 9 are too long to be accommodated inside the packaging box when they are closed.

Further, if an arbitrary number of break lines orthogonal to the fold lines A provided on the lid plates 7 and 9 are provided at arbitrary intervals, the side end inside the packaging box can still contain the packaged product. Even if there is a space in the part, after storing the packaged product and closing the cover plates 7 and 9 according to the size of the packaged product, the breaking line B of the cover plates 7 and 9 is set to the size of the packaged product. When it is broken according to its shape, the packaged product can be fixed according to its size.

It is to be noted that if the portions of the lid plates 7 and 9 from the sides of contact with the side plates 2 and 4 to the first folding line are lightly folded inside the surfaces of the lid plates 7 and 9 in advance, they will face each other. Fixing of the packaged products in the ideal state of the lid plates 7 and 9 is performed extremely smoothly.

The fourth bottom plate 13 is folded inside the surface of the fourth side plate 4 at a right angle with the side of contact with the fourth side plate 4 as an axis. The contact portion between the third bottom plate 12 and the back surface of the fourth bottom plate 13 is bonded.

According to the procedure described above, the side plate and the bottom plate are assembled, and the packaged product can be housed inside. Next, the procedure for closing the lid plates 6, 7, 8 and 9 will be described by taking two states as an example.

First, an example in which the side plates 1, 2, 3, 4 and the bottom plates 10, 11, 12, 13 are assembled. Inside the packaging box, the lid plates 6, 7, 8 are packed with the packed articles as much as possible. , 9 is described below. The second cover plate 7 and the fourth cover plate 9 are folded in an arbitrary order inside the surfaces of the side plates 2 and 4 which are connected to each other and at a right angle. Then, the first cover plate 6 and the third cover plate 8 are folded inside the surfaces 1 and 3 of the side plates connected to each other. FIG. 4 is a vertical front view showing the state at this time.

Next, when the articles are packaged in the packaging box of the embodiment in which the side plates 1, 2, 3, 4 and the bottom plates 10, 11, 12, 13 are assembled, and there is a space above the inside of the packaging box. Will be described. The second cover plate 7 and the fourth cover plate 9 are folded inside the surface and at an acute angle with the perforations A having the midpoints of the short sides at both ends as an axis. Figure 5 shows the state at this time. The second cover plate 7 and the fourth cover plate 9 are then folded at a right angle to the inside of the surfaces of the side plates 2 and 4 which are respectively connected to each other. FIG. 6 is a perspective view of the state at this time and the inside is seen through. The first cover plate 6 and the third cover plate 8 are folded at a right angle to the inside of the surfaces of the side plates 1 and 3 which are connected to each other.

As it is folded, the portion of the second cover plate 7 and the fourth cover plate 9 from the perforation having the short side midpoints at both ends to the long side opposite to the contact side with the side plates 2 and 4 , Stick to each other. The parts of the perforations that are in close contact with each other vertically contact the package. Then, fold the perforations and close the lid so that the height corresponding to the height of the space remaining above the package is left. FIG. 7 shows this state in a vertical sectional front view.

As a result, the second lid plate 7 and the fourth lid plate 9, which are folded into an L shape or a rectangle, hold and fix an arbitrary amount of the package as long as the package can be stored in the packaging box. It becomes possible to do. In this case, if the perforations are lightly folded inward on the inner surfaces of the side plates 2 and 4 so as to be easily bent, it becomes easy to fix an arbitrary amount of the packaged product in an ideal state. In this embodiment, a packaged product that leaves a space above the inside of the packaging box can be fixed in five stages.

The present embodiment in which the lids 6, 7, 8, 9 are closed by the above-mentioned procedure becomes one rectangular parallelepiped. As shown in FIG. 8, it is also possible to provide an arbitrary number of break lines B orthogonal to the fold lines A provided on the lid plates 7 and 9 at arbitrary intervals.

Depending on the packaged product, its size may be considerably smaller than the volume inside the packaging box. In that case, a space may remain at the side end inside the packaging box. Therefore, if the package B is accommodated and the lid plates 7 and 9 are closed according to the size of the package, the break line B of the lid plates 7 and 9 is broken according to the size and shape of the package. , Package can be fixed according to its size.

[0046]

【effect】

 According to the present invention, by providing an arbitrary number of folding lines A orthogonal to the opening / closing direction of the lid plate at least at one of the front surface and the back surface of the lid plate at an arbitrary interval, the packaging box can be provided. Depending on the size of the packaged product to be accommodated, the remaining space can be filled with the lid that is folded along the folding line A, and as a result, the packaged product can be fixed.

Therefore, it is possible to prevent the package from swinging when the packaging box is transported or moved, and to prevent the package from being damaged as much as possible. Furthermore, if one type of packaging box is prepared, it is possible to accommodate a packaged article of any size as long as the packaged article can be accommodated inside the packaging box.
