  The present invention relates to a joint structure of a packaging container that stores equipment and the like inside.

In the case of a packaging container for storing information equipment such as a copying machine, if the height of the container is large, a space for removing the exterior cannot be provided at the upper portion, and the container collides with the ceiling. For example, when the information device main body has a height of 143 cm or more, an installation ceiling height is 3 m, and a packaging pallet height is 15 cm, in the case of an exterior of a packaging container having a height exceeding 140 cm, the packaging container hits the ceiling. , It is difficult to remove the packing container.
On the other hand, if the package can be tilted, such as a refrigerator, in a packed state, the packing box can be pulled out in the height direction. However, when information devices and the like are housed, they may be packaged with pallets or the like according to the product specifications, and it is difficult to tilt the packaging container, and therefore, there are restrictions on unpacking.

  In a conventional packing container, for example, in Patent Document 1, the upper plate 1 and the lower plate 4 are provided with handle holes 2 and 5 and ruled lines 3 and 6 for forming side plates 7 and 8, respectively. When they are placed in a U-shape facing each other in the vertical direction, the handle holes overlap each other to form a through hole 12, and a stopper (including tape, wire, and adhesive) 13 is attached to the through hole 12. Then, the side plate 7 and the side plate 8 are joined to each other, and the upper plate 1 and the lower plate 4 form a box.

  Patent Literature 2 provides a technique for reducing the amount of foamed plastic or the like as much as possible when packing heavy packaging materials such as a printer, thereby facilitating the collection and disposal of packing materials and reducing the cost of packaging. The side surface of the product is buffered by using a body frame and a band that wrap the product, thereby eliminating the side cushioning member and reducing the cost. Specifically, two rows of cuts having a fixed length perpendicular to the vertical ridge are provided in the middle of the vertical ridges at the four corners of the package box body, and the two rows of cuts are inserted into the packing box body inside the W-shaped staircase in plan view. Forming a W-shaped recess at the corners of the four corners of the package box body by folding it into a shape, passing through the W-shaped recess, performing banding to tighten the four corners of the product from the outer surface around the product stored in the box, The product body and the package box body are integrated.

  The structure of Patent Literature 3 is a structure in which first and second tubular members having the same shape in the direction perpendicular to the axis are provided and connected by connecting them at a connection end. A first and a second slit extending along the axis from the edge, an outer overlapping portion located on one side between the first and second slits, and a second side between the first and second slits on the other side. And an inner overlapping portion that is positioned, wherein the first slits of the first and second tubular members are engaged with each other, and the second slits of the first and second tubular members are engaged with each other, Alternatively, the second slit of one of the first and second tubular members is engaged with a wall surface of the other connecting end, and the outer overlapping portion of one of the first and second tubular members is engaged. Superimposed on the outside of the other inner superimposed portion It is to be connected to.

  In Patent Document 4, in a two-piece packaging box including an outer case (1) having an open bottom surface and a tray (2) for covering the outer case from above, a two-piece packaging box is provided at the bottom of the side wall (3) of the outer case (1). An engaging piece (10) is provided, a portion between the notch lines (12) cut from both ends of the base of the engaging piece (10) is used as a releasing piece (13), and the side wall (22) of the tray (2) has a multiplex structure. A concave portion (28) is formed on the outer surface of the outer case by folding the engaging piece (10) inward, and the skirt of the side wall (3) of the outer case (1) is attached to the side wall (2) of the tray (2). 22), the engaging piece (10) fits into the recess (28), the outer case (1) and the tray (2) are fixed, and the release piece (13) is turned up and cut. When the line of sight (12) is broken, the outer case (1) and the tray (2) are separated from each other. Packaging box is disclosed.

However, in Patent Document 1, although it has two upper and lower configurations, a stopper is indispensable in packing, and parts other than a box material (for example, cardboard) are required.
In Patent Literature 2, the packaging material is placed on the four corners, but is not supported in the left-right direction, and the movement is allowed.
In Patent Literature 3, two members having the same cut shape are connected, and the shape is restricted. In addition, one of the first and second tubular members overlaps the outer overlapping portion with the outside of the other inner overlapping portion, and sufficient rigidity cannot be obtained. In addition, when the cut has an outer shape, the length of the outer circumference increases, and the rigidity decreases particularly around the cut.
In Patent Document 4, the removal of the packaging container is not improved.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a joint structure of a packaging container that can be easily unpacked even if there is little space around the container.

That is, in the joining structure of the packing container of the present invention, the first mode is a joining structure of a packing container which is divided into two or more packing members and the packing members are joined to each other,
In the first packing member and the second packing member that are joined to each other, the first packing member is provided on both sides of at least one corner of the joining side end of the first packing member along the dividing direction. The first packing member is fitted into each of the first notches at a joint side end of the second packing member, at a corner corresponding to a corner of the first packing member. Having a fitting portion located inside the portion, and further comprising a covering portion located so as to cover the outside of the joining end portion of the first packing member at the outside of the first cutout connected to the fitting portion,
The fitting portion has a shape that is positioned with a gap between the inner surface of the corner of the first packing member and the fitting portion.

  In another aspect of the present invention, the second packing member has a second cut at a corner of a joining side end in a direction intersecting with a dividing direction. The corner located on the tip side of the notch 2 is folded inward to form the fitting portion.

  In another aspect of the present invention, the first cutout of the first packing member has a length from the position of the second cutout of the second packing member to the joining edge. It is characterized by being longer.

  According to another aspect of the present invention, there is provided a joining structure of a packing container, wherein the fitting portion of the first packing portion has a third cut inserted along the dividing direction into the first cut in the fitting portion of the first packing portion. And

  In another aspect of the present invention, the length of the third cut is smaller than the length of the first cut.

  In another aspect of the present invention, the cover is bent inward on both sides of the corner of the second packing member to form the fitting portion.

  According to another aspect of the present invention, there is provided a bonding structure of a packaging container, wherein at least one of the corner of the first packaging member and the second packaging member has a corner.

  In another aspect of the present invention, when the number of packing members to be bonded is three or more, the number of the second packing members is larger than the number of the first packing members. It is characterized by the following.

  In another aspect of the present invention, at least one division direction is a height direction.

  In another aspect of the present invention, the outer dimensions of the second packaging member are larger than the outer dimensions of the first packaging member in an outer dimension in a direction perpendicular to the dividing direction.

  According to another aspect of the present invention, the joint structure of the packing container is such that the cutout according to the size of the packing box is provided in the same packing portion in the invention of the above-mentioned form, so that the same can be used commonly for packings having different sizes. I do.

According to the present invention, the following effects can be obtained.
Unpacking can be easily performed in a space with a small space, for example, a place where the ceiling is low, even if there is little space around the space.
・ Since high-cost connecting members (other than corrugated cardboard) are not required for the exterior of a horizontally-opening type packing box with one-side stitching using existing connecting members, it is cheap and easy to separate at the time of disposal. Can be.

・ Since the packing box can be opened upward without tilting the product, one person can easily work.
As a preferred form of strength,
-Since the connection is made by the cut shape provided on one side of the packing member, a packing box having high strength against a load from the side can be obtained. When wrapping a package with a connecting member or the like, the end moves when unpacking, and there is a concern that the product, surroundings, and people may be hit.
・ Information devices have multiple sizes of similar packing boxes, such as destinations and minor changes. However, by adopting a divided packing configuration, the required base material can be made smaller and simpler, and the cut-out configuration can be made more than one size. Deployment becomes easy.
-The printing information required for the packaging box is divided and printed for each of a plurality of packaging boxes, so that the packaging box can be partially shared. For example, a company name or the like can be printed on a first packing member that can be used in common, and machine information or the like can be printed on a second packing member.

It is a perspective view explaining division and connection of a packing member in a packing container in one embodiment of the present invention. It is an enlarged view of the joining part in the packing container of FIG. It is a figure explaining an example of packing. FIG. 4 is an enlarged view of a joint portion in the packing container of FIG. 3. It is a figure showing other joining structures in a packing container. It is a figure explaining the behavior to load in an embodiment and a conventional example. FIG. 9 is a diagram illustrating commonality between a conventional example and an embodiment. It is a figure explaining the example which sets a reference | standard and makes it common. FIG. 9 is a diagram illustrating a structure in a conventional example. FIG. 11 is a diagram illustrating a structure in another conventional example. It is a figure explaining the structure of the packing container in a conventional example.

Hereinafter, the connection structure of the packaging container of the present invention will be described with reference to the accompanying drawings.
The packing container 1 has packing members 2 and 3 in which the packing members are separated vertically. In the left diagram of FIG. 1, the packing members 2 and 3 are separated, and in the right diagram of FIG. 1, the packing members 2 and 3 are separated. It shows a state of being joined and connected.
In this embodiment, the packing container 1 is divided into two packing members in the height direction. However, as the present invention, the dividing direction is not limited to a specific direction. It may be divided in an oblique direction, or may be divided in a plurality of directions.

In the packing members 2 and 3, cuts 21 are formed perpendicularly to the upper ends on both sides of the four corners 20 of the packing member 2, that is, along the dividing direction, and the corners 30 of the four corners of the packing member 3 are formed. A notch 31 is formed at the lower end of the notch horizontally, that is, crossing in the dividing direction, and the lower side of the notch 31 is folded inward to have an inner angle. This folded portion corresponds to the fitting portion 32 of the present invention. The corner 20 and the corner 30 are corners.
Therefore, in this embodiment, the packing member 2 corresponds to the first packing member of the present invention, the cut 21 of the packing member 2 corresponds to the first cut of the present invention, and the packing member 3 corresponds to the second cut of the present invention. The cut 31 of the packing member 3 corresponds to a packing member, and corresponds to the second cut of the present invention.

FIG. 2 shows details of the above configuration. In the packing member 3, at a position corresponding to the notch 21 in the corner 20 of the packing member 2, a lower end side is folded inward to form a fitting portion 32 having an inner angle of approximately 90 degrees, and both ends thereof are cut 21. And joined.
Note that the length of the cut 21 is larger than the vertical length of the fitting portion 32 below the cut 31.

  Above the fitting portion 32, the lower end surface of the packing member 3 overlaps the upper end side outer side of the corner 20 of the packing member 2. Further, on both sides of the fitting portion 32, a lower piece of the packing member 3 is continuous, and this lower piece is positioned as a covering portion 33 which overlaps an outer edge of an upper end edge of the packing member 2. In this embodiment, the cover portion 33 overlaps the upper end piece of the packing member 2, but may have a gap between both. By adjusting the length of the cut 21, the amount of overlap between the fitting portion 32 and the cover portion 33 with respect to the packing member 2 can be adjusted.

In this embodiment, since the fitting portion is folded inward, the outer peripheral length of the packing member does not increase, and the rigidity can be maintained.
The cuts 21 are located on both sides of the corner, but the position is not limited to a specific position. If the notch is far away from the corner, the rigidity decreases. For this reason, for example, it is desirable that the position of the notch be about 1/4 or less of the dimension of the packing member. The specific length depends on the size of the packing member, but is preferably about 20 or 30 cm within 50 cm from the center of the corner.

In the following, a description will be given of a packaging container which has been a problem in the related art.
FIG. 9 illustrates a case where the image forming apparatus is housed in a packing container as a heavy information device. In this packing container, a sleeve (copper box) -shaped packing box is mainly used, and a bottom cover and an upper cover are additionally provided. The packaging box has a shape without flaps on the top and bottom surfaces.
For example, if the height of the pallet is 150 mm and the height of the product is 190 cm in a space having a ceiling height of 3 m, a box having a height exceeding 140 cm has a problem that the box collides with the ceiling when unpacking.

Heretofore, in addition to the above, there has been known one in which a packing container is manufactured by a joint.
As shown in FIG. 10, a packing container is delivered in a plate shape, wound around a product, and joined with a joint (made of resin). For example, one to two cardboards and four to eight joints are used. For packing, put the joint in the hole and close the joint lock. For unpacking, open the joint lock, remove the joint and open the cardboard.
This configuration has the advantage that, since it can be joined after being wound around the product, no space in the height direction is required, and attachment / detachment can be repeated, so that it is possible to cope with any modification of the contents.
However, if the cost of the joint is high and the cardboard is a single piece of cardboard, take up the space for cardboard when delivering. When the cardboard is a two-piece cardboard, there is a problem that two people may be required.

Heretofore, there has been known another type in which a package is manufactured by stitching.
In this method, the product is delivered in the form of a plate, wound around the product, and joined by stitching. This packing container can be constituted by one cardboard.
For packaging, stitch the cardboard joints and cover the sleeve from above. When unpacking, cut around the joint with a cutter and open the cardboard.
The production of this packaging container has the advantage that the cost is low.
On the other hand, the following are disadvantages.
A space in the height direction is required to make the sleeve shape first.
If the cardboard is a single piece of cardboard, take up the space for cardboard at the time of delivery.

In the above two types of packing containers, when a sleeve can be covered, by providing an overlapping portion as shown in the left diagram of FIG. 11, the packing container can be prepared in a size that does not hit the ceiling. On the other hand, when the sleeve cannot be covered, a packing container is prepared by a joint. In the above manufacturing method, the packing container shown in FIG. 10 is higher in cost, and therefore, the stitched packing container is used preferentially.
As described above, in the above two types of packing containers, fasteners are essential for component parts, so parts other than box materials (for example, cardboard) are required, and some of the fasteners can be diverted May not be possible, and lacks versatility.
On the other hand, in the present embodiment, as will be described below, it is possible to form a single member (material), rather than using a connection member that can be easily deployed.

Next, a packing example of the present embodiment will be described with reference to FIGS.
3 is a bottom view (upper side) and a side view (lower side) of the packing member 2 (shown as A for convenience in the figure), and a bottom side (upper side) of the packing member 3 (shown as B for convenience in FIG. 3). A side view (lower side), a bottom view (upper side) and a side view (lower side) in a connection cross section of the packing container connected to the right side are shown.
Examples of the product include an information device having a weight ranging from several tens of kg to several hundred kg. However, the present invention is not limited to specific items.

  In this embodiment, among the four corners of the packing member 3, the above-described fitting portions 32 are provided at three corner portions 30, and the other of the four corner portions are provided with the second cut-out portions and the fitting portions folded inside. It is not provided, and has a corner portion 30A which is inclined between positions corresponding to the cut positions of the packing member 2, and this corner portion is a fitting portion 32A.

  In this embodiment, one of the corners is slanted because the stitching portion avoids making a cut. Of course, it is possible to make the fitting part 32 in the same manner as the other corners in the stitched part. Further, a configuration in which all four corners of the packing member 3 are inclined is also possible. In this case, the packing member has an octagonal cross section.

As shown in the right side of FIG. 3, the packing members 2 and 3 are provided with unpacking handles and the like, and are connected to each other.
With the two-tiered structure, when a sleeve is stacked on a product, the space required in the height direction is reduced by half, and packing and unpacking work can be performed by one person.
The vertical positions of the packing members 2 and 3 are not particularly limited, and the packing member 3 may be placed below and the packing member 2 may be placed above. Further, the number of divisions may be three or more.

FIG. 4 is a diagram for explaining the packing state in FIG.
This shows in detail a bonding state when the corner of the packing member 3 is not a corner but an oblique surface. The packing member 3 has the fitting portions 32 at the three corners 30 and the oblique fitting portions 32A at the corners 30A. The respective fitting portions 32 and 32A are fitted into the cuts 21 of the packing member 2, and the packing member 2 and the packing member 3 are joined.

FIG. 5 is a diagram illustrating a modification. In this embodiment, similarly to the above-described embodiment, corners 30 are provided at the four corners. At each corner 30, a cut 31 is formed, and a lower piece thereof is folded inward to provide a fitting portion 32. ing.
Further, in this embodiment, a notch 34 is formed at each fitting position of the fitting portion 32 with respect to the cut 21 along the dividing direction, that is, the height direction. The notch 34 corresponds to a third notch of the present invention.
The notch 34 has a length smaller than the height of the fitting portion 32. The fitting portion 32 and the cover portion 33 are connected by a side on the notch 34. The notch 34 has a shorter length than the notch 21, and the ratio of the length of the fitting portion to the length of the notch 21 can be adjusted by the length.

Next, the rigidity of the packaging container according to the present invention and the conventional packaging container will be described with reference to FIG.
The upper part of FIG. 6 shows a conventional packaging container. When a load is applied from the side in a state where the product is stored, there is a possibility that the packing material is crushed at one piece length L1 and collides with the product as shown in the second diagram from the right showing the AA cross section.

On the other hand, in the embodiment of the present invention, there is a distance to the product even if the packing material is crushed against the load from the side, and the length L2 of the side is shorter than the conventional length L1 (L1> L2). The amount of deflection is reduced.
Then, the deformation of the packing material due to the load is restricted by the notch joints at the four corners, and the effect of suppressing the deformation of the whole packing material can be expected.
In this embodiment, the total number of the packing members 2 and 3 is an odd number, and the number of the packing members 3 is larger than the number of the packing members 2.
Further, the outer dimension of the packing member 2 in the horizontal direction, that is, the outer dimension in the direction orthogonal to the dividing direction can be made smaller than the outer dimension of the packing member 3 in the horizontal direction.

Further, according to the present invention, the joining structure can be simplified, and the packaging can be shared.
The figure shown in the upper part of FIG. 7 shows the case of a conventional packing container.
If the equipment is expensive or space is required for accessories when the packing container shown in the upper left figure is available, it is necessary to prepare a different packing container as shown in the center figure on the upper part and the figure on the right. There is.

On the other hand, in the embodiment of the present invention, as shown in the lower part of FIG. 7, a part of the packaging can be shared and used for the packaging of the product whose destination is changed such as the accessory. In this example, the packing member A can be shared, and the packing members B, C,... Can be expanded to prepare a packing container. Since a non-common packaging member is reduced in size, a packaging container can be easily manufactured, and costs can be reduced.
Similarly, when a part of the printing is changed, it is easy to make a small packing member.
That is, even if the height of the contents changes, another packing member having a different height is prepared using the common packing member, and a packing container can be obtained by connecting these.

Although the case where the heights are different has been described above, the height may be common and the lateral dimensions may be different. In this case, it is necessary to prepare a packing member according to a change in size.
For example, as shown in FIG. 8, when a model 1 or a model 1 minor change is required, a package that can be shared is prepared based on the size as shown in the bottom diagram of FIG. Pre-processing for joining) can be performed in common, and cut to the size of use so that a packaging member can be manufactured.

In the present embodiment, the cardboard of the packing box used in the information equipment is thicker and stronger than a general cardboard. Therefore, even if a cut is provided at the corner or in the vicinity thereof, it can be combined with the other cardboard. Strength can be ensured (other than vertical).
In the case of divided packages, it is necessary to reduce the tolerance between the two dimensions or to allow backlash between the two parts. The difference can be increased and the play can be reduced.

In the present embodiment, the allowable width for the two dimensional tolerances is large. (In the case of a connection with a step at the top and bottom, there is a high demand for dimensional control).
The power supply can be secured only by unpacking the upper package exterior, and work such as ROM collection is possible. In addition, it is easy to return to the packed state (in the situation of unpacking and setting up, there is no fear of impact from the side, etc., and the structure has sufficient strength).
The same packing box can be configured for different destinations even if the packing amount changes. Or can be used (Fig. 6)
In the vertical direction, since the area of the upper and lower joints is small, it is not strong, but it is strong against the side load.
Five degrees of freedom excluding the direction in which the packing members are divided can be restricted.

  As described above, the present invention has been described based on the above-described embodiment. However, the technical scope of the present invention is not limited to the contents described in the above-described embodiment, and unless the present invention deviates from the scope of the present invention. Appropriate changes to the above embodiment are possible.
