Description

  The present invention can alleviate external vibrations and shocks during transportation, storage, and handling of a packaged item, and also minimizes the amount of cushioning material used at that time while packing the packaged item inside It is related with the packing container which consists of a packing box which can fix reliably, and a buffering fixture for packing.

Conventionally, when packing an item to be packed that is relatively lightweight or less likely to be damaged by vibration or shock, the packaged item is stored in a rectangular parallelepiped packing box, and used paper is placed in the gap. It was used as a cushioning fixing material by packing rounded materials, foamed plastic chips, and amorphous materials such as cardboard scraps.
On the other hand, when transporting things that are slender and heavy, such as rails, and that may be damaged by vibration or impact, for example, only the above-mentioned amorphous cushioning material is packed. However, since a sufficient buffering effect cannot be expected, it has been necessary to carry out the transportation or the like by securely fixing an object to be packed using a buffer fixing material having a specific shape in a rectangular parallelepiped type packaging box.
In this case, for example, cardboard, cardboard, plastic board or the like is cut into a predetermined shape, and further, a notch is formed or bent, or a plurality of items assembled into a predetermined shape are combined or bonded together. In addition, a box shape, a cross girder partition, or a molded plate shape was used as a buffer fixing material.
In recent years, such buffer fixing materials often use cardboard molded products suitable for recycling. Especially when heavy objects are buffered and fixed in a rectangular parallelepiped type packaging box, the cardboard is rectangular parallelepiped type or rectangular column shape. In many cases, the assembly was used.

Below, the buffering fixture for packing which concerns on a prior art is demonstrated, referring FIG.
Fig.9 (a) is a conceptual diagram of the buffering fixture for packing which concerns on a prior art, (b) is the expanded view.
As shown in FIG. 9 (b), the rectangular columnar packing buffer fixture 50 according to the prior art is mainly used when packing a long and narrow packaged object, and cuts a flat buffer material. It is assembled and used in a rectangular parallelepiped shape by hand.
Such a cushioning fixture 50 for packing according to the prior art is composed of a cushioning material 51, and is diagonally reinforced so as to connect a pair of opposing corners of a quadrangular prism as shown in FIG. 9 (a). The cover 54 is provided with folding portions 55 and 55 that are folded into the openings while covering the openings at both ends of the quadrangular prism, and is configured to prevent deformation and crushing of the packing buffer fixture 50 due to external force.
In addition, since the body portion of the packing buffer fixture 50 is provided with a notch 53 that fits into the shape of the package object, at least two packing buffer fixtures 50 are straddled over the package object 56. The packed object 56 is fixed in the packing box 57.
Further, the packing buffer fixture 50 includes a joint surface where the end portions of the cushioning material 51 constituting the quadrangular column overlap each other, and pressing portions 52a and 52b are provided on the joint surface. In addition, since the pushing portions 52a and 52b are provided at positions where they coincide with each other, when the cushioning material 51 is assembled into a quadrangular prism shape, the pushing portions 52a and 52b are overlapped and pushed into the quadrangular column, It is comprised so that the shape of the buffering fixing tool 50 for packing can be hold | maintained, without using bonding materials, such as an adhesive tape.
Further, by reversing the top and bottom of the packing buffer fixture 50 as shown in FIG. 9A, it is also possible to hold the packaged object 56 in a floating state in the packing box 57.

Japanese Patent Application Laid-Open No. H10-228707 discloses a device related to a base that is installed on the inner bottom of a box in which a heavy article is packed and supports the heavy article under the name “heavy article packaging base”.
The device according to Patent Literature 1 is configured by forming a rectangular columnar girder member having a substantially trapezoidal cross section by bending a flat cushioning material, and folding and accommodating the buffer material integral with the girder member therein. The load resistance of the girder member is improved.
Moreover, the notch is provided in the trunk | drum of the girder member which concerns on the said device, and rocking | fluctuation of a heavy article can be prevented by making the notch of the girder member and the bottom part of a to-be-packaged item fit. .

Japanese Utility Model Publication No. 7-21574

However, when a square tube having a substantially square cross section is adopted as the buffer fixture, like the packing buffer fixture 50 according to the prior art, such a square tube can be rephrased as, for example, a building structural material. It can be said that the structure consists of columns and beams. Such a structure composed of pillars and beams exhibits strength against a force acting in the vertical direction, but has a characteristic that it is particularly weak against a force from a horizontal direction or an oblique direction.
Therefore, in order to make up for this weak point, for example, it is necessary to provide reinforcing members such as braces or to add a reinforcing surface material to make the rectangular tube into a rectangular column. In this case, the cushioning fixture 50 for packing is formed. The development of this will become complicated and the amount of cushioning material used will also increase. As a result, there has been a problem that the cost for manufacturing the buffering fixture 50 for packing becomes expensive.
When manufacturing such a buffering fixture 50 for packing, if a rectangular cushion is formed by cutting out a rectangular cushioning material as shown by the dotted line in FIG. 9B, the hatched portion becomes unnecessary and discarded. It must be wasteful. For this reason, there also existed the subject that the cost concerning disposal increased.
Furthermore, in the cushioning fixture 50 for packing according to the prior art, although the cushioning material 51 can be held on the square pillar without using a bonding material such as an adhesive tape, in order to provide the pushing portions 52a and 52b, It was necessary to overlap the end portions of the buffer material 51 to form a joint surface. And when the buffering fixture 50 for packing is large, in order to form a joining surface, the buffer material 51 of a large area is required, and possibility that cost may cost compared with the case where joining materials, such as an adhesive tape, are used. Yes, it could be uneconomical.
In addition, the packing buffer fixture 50 according to the related art is generally assembled manually, but is fixed with one hand so that the diagonal reinforcing portion 54 is arranged at an appropriate position during the assembly. However, it was particularly troublesome because it was necessary to assemble it into a quadrangular prism. For this reason, when assembling the buffering fixture 50 for packing which concerns on a prior art, the time which it takes becomes long, and the labor cost increases correspondingly, There also existed the subject that the unit price of the buffering fixture 50 for packing rose.
In addition, such a packing buffer fixture 50 according to the prior art, when transported for disposal or recycling after use, is bulky in this state, and thus has to be disassembled.
In this case, it is necessary to pull out the pushing portion 52a pushed into the rectangular column of the packing buffer fixture 50 and disassemble it. For this purpose, first, the folding portion 55 is opened, It is necessary to insert a finger into the rectangular column from the opening at both ends and push out the pushing portion 52a to the outside, or insert a finger into the inside of the square column from the notch 53 and push the pushing portion 52a outward. It was complicated.

Further, in order to improve the load resistance of the girder member in the conventional “base for packing heavy objects” as disclosed in Patent Document 1 described above, the number of times of folding of the reinforcing member folded into the girder member is set. However, in this case, there is a problem that the labor cost for assembling is high and the cost of the “base for packing heavy objects” according to Patent Document 1 is increased.
In addition, the device according to Patent Document 1 relates to a base used when packing a substantially rectangular parallelepiped heavy object such as a washing machine or a refrigerator, supports a packaged object, and has load resistance. However, it does not have an effect of reinforcing the side surface or the upper surface of the packaging box that accommodates the item to be packed. For this reason, in order to reinforce the upper surface and side surface of a packaging box, it was necessary to prepare a buffer material separately.
And although the device which concerns on patent document 1 fixes the elongate and heavy to-be-packaged object like a rail in the rectangular parallelepiped type packaging box, for example, the packaging box cannot be reinforced from the inside.

[1] Hereinafter, a packaging container according to a first embodiment of the present invention will be described with reference to FIGS. (Especially corresponding to claims 1 to 5)
FIG. 1 is a conceptual diagram showing a usage state of the packaging container according to the first embodiment of the present invention.
As shown in FIG. 1, the packaging container 1a _{1 according} to the first embodiment of the present invention is composed of a packaging box 9 and a cushioning fixture 2a ₁ for packaging, and at least two packages are provided inside the packaging box 9. By providing the buffer fixing tool 2a ₁ for use, the long and heavy packaged object 10a can be reliably fixed.
Packaging container 1a ₁ of the present embodiment is one having a particular characteristic to the arrangement of the packing buffer fixture 2a ₁ in the packing buffer structure of the fixture 2a ₁ and the packaging box 9, the present embodiment The packaging box 9 is a cubic housing made of a material having rigidity and buffering properties such as cardboard, for example, and is provided with a lid on its upper surface or as a separate body.
The material constituting the packaging box 9 and packaging buffer fixture 2a ₁ is not particularly limited, cardboard, cardboard, thick paperboard, cardboard-like molded plastic plates, etc. foamed plastic plate is suitable. These materials may be used alone, or a plurality of types of materials may be used in combination. The same applies to other embodiments described in this specification.

First, a packing buffer fixture according to the present embodiment and a modification thereof will be described with reference to FIGS.
2 (a) and 2 (c) are conceptual views of the cushioning fixture for packing according to the first embodiment of the present invention, respectively. (B) and (d) are FIGS. 2 (a) and (c), respectively. ). 3 (a) to 3 (d) are cross-sectional views showing modifications of the packing buffer fixture shown in FIG. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
As shown in FIG. 2A, the packing buffer fixture 2a ₁ according to the present embodiment includes a triangular cylinder body 3 formed by bending the buffer material 4, and end portions 7a and 7a of the buffer material 4. It is comprised by the joining material 5 which fixes the one part in the state which contacted.
Moreover, the notch part 6 which fits with the to-be-packaged object which is not shown in figure is provided in the trunk | drum of the three side surfaces which comprise the triangular cylinder main body 3, By fitting this notch part 6 and the to-be-packaged object, An object to be packed is fixed inside the packing box 9.
Further, as shown in FIG. 2B, the developed view of the packing buffer fixture 2a ₁ according to the present embodiment is a very simple one in which the cut-out portion 6 is provided in the rectangular buffer material 4.
If such a triangular cylinder constituting the packing buffer fixture 2a ₁ is replaced with, for example, a structural material for construction, it can be said that the structure has both pillars, beams and braces. Such a structure exhibits excellent strength in any of the forces from the vertical direction, the horizontal direction, and the oblique direction.
Therefore, it is not necessary to separately provide a bracing member or a reinforcing surface material in order to stabilize the triangular cylinder body 3 constituting the packing buffer fixture 2a ₁ . For this reason, the punching plan development view for forming the buffering fixture 2a ₁ for packing can be made extremely simple. Therefore, it has the effect that the buffering fixture 2a ₁ for packing provided with load resistance can be created with a minimum amount of cushioning material.
Furthermore, with the simplification of the punched plane development view for manufacturing the buffering fixture 2a ₁ for packing, there is also an effect that it is possible to reduce waste when the flat cushioning material is punched and formed.
Further, since the packing buffer fixture 2a ₁ has a very simple structure, the time required for the assembly work can be greatly reduced. In addition, the time required for the assembly work can be further shortened by fixing the end portions 7a and 7a of the cushioning material 4 using the bonding material 5.
As a result, the labor cost at the time of assembling the packing buffer fixture 2a ₁ is reduced, and a particularly excellent effect that the cost for manufacturing the packaging container 1a _{1 according} to the present embodiment can be greatly reduced is exhibited. It is.

Further, in order to prevent damage to the object to be packed is to be accommodated, the pressure and impact from the outside, or is packed in the vibration chamber 1a ₁ is the need to increase the strength of the packaging box 9 itself so as not to crush deformation In the packaging container 1a _{1 according} to the present embodiment, as shown in the previous FIG. 1, both ends forming the triangle of the triangular cylinder body 3 in the packaging buffer fixture 2a ₁ are the left and right side surfaces of the packaging box 9. Further, the contact portion 7 of the triangular cylinder body 3 is configured to be in surface contact with the upper surface of the packaging box 9, and further, the bottom surface 8 of the packaging buffer fixture 1 a ₁ is in surface contact with the bottom surface of the packaging box 9.
For this reason, the force acting on the left or right side of the packaging box 9 can be distributed to the right or left side of the packaging box 9 via the triangular cylinder body 3, and the force acting on the top or bottom surface of the packaging box 9 is It can disperse | distribute to the lower surface or upper surface of the packaging box 9 via the triangular cylinder main body 3, As a result, the packaging box 9 does not crush and deform | transform easily.
Thus, in the packaging container 1a ₁ according to the present embodiment, the packaging buffer fixture 2a ₁ itself is brought into contact with the packaging box 9 by bringing the contact portion 7 and the bottom surface 8 of the packaging buffer fixture 2a ₁ into contact with the packaging box 9. Since it functions as a reinforcing member of the packing box 9, that is, a bracing member, it has an effect of reliably preventing crushing deformation of the packing box 9 when an external force is applied to the packing box 9.

Further, it is desirable that the triangular cylinder body 3 related to the packing buffer fixture 2a ₁ is an isosceles triangular cylinder, and a regular triangular cylinder is optimal.
Thus, by making the triangular cylinder main body 3 related to the packing buffer fixture 2a ₁ into an isosceles triangular cylinder, two forces acting on the upper surface / lower surface of the packaging box 9 are transmitted via the contact portion 7 or the bottom surface 8. Since the load is evenly distributed on the side surfaces, there is little possibility that the load is concentrated only on the specific side surfaces. Therefore, the triangular cylinder body 3 is not easily deformed by crushing. This effect is most prominent when the triangular cylinder body 3 is a regular triangular cylinder, and the regular triangular cylinder is optimal for the triangular cylinder body 3.
Further, when the triangular cylinder body 3 of the packing buffer fixture 2a ₁ shown in FIG. 2 is an isosceles triangular cylinder, the angle θ formed by the isosceles surface is preferably set in a range of 45 ° to 75 °. .
This is because, as the angle θ formed by the isosceles surface becomes smaller than 45 °, the area of the bottom surface 8 becomes relatively narrow, and it becomes difficult to bend the cushioning material 4 having a thickness at the time of assembling work, and the workability is lowered. In addition to this, there arises a problem that the stability when the packaging buffer fixture 2a ₁ is installed in the packaging box 9 is extremely lowered. In this case, during transport of the object to be packed 10a, there is also a risk of overturning packing buffer fixture 2a ₁ by vibration or impact, it is possible that the buffer effect is not sufficiently exhibited.
On the other hand, when the angle θ formed by the isosceles surface is set to be larger than 75 °, the tendency to reduce the load resistance in the vertical direction starts to appear, and this tendency indicates that the angle θ formed by the isosceles surface exceeds 90 °. Especially in cases.
Accordingly, it is desirable that the triangular cylinder main body 3 constituting the packing buffer fixture 2a ₁ according to the present embodiment is an isosceles triangular cylinder. In this case, the angle θ formed by the isosceles surface is 45 ° to 75 °. It is desirable to set the range.
Further, the packaging container 1a ₁ according to this embodiment, for example, are particularly suited for packaging elongated a weight object to be packed 10a such as a rail or the like. In this case, it is possible to reliably fix the object to be packed 10a by providing the packing buffer fixture 2a ₁ of at least two within the packaging box 9 of the packaging container 1a _1. Further, when the object to be packed 10a is particularly long, it is desirable to place the packing buffer fixture 2a ₁ at fixed intervals in order to enhance the reinforcing function of the packaging box 9.

Further, as shown in FIG. 2 (a), the contact portion 7 is preferably provided on the top side formed by two isosceles surfaces, and the contact portion 7 is preferably in contact with the upper surface or the lower surface of the packaging box 9, The load resistance of the cushioning fixture 2a ₁ for packing is maximized.
When the contact portion 7 is arranged in this way, for example, when pressure is applied from the outside of the packaging box 9, the two isosceles surfaces are pressed against each other at both ends 7 a and 7 a of the cushioning material 4, that is, the contact portion 7. Since the force which fits acts, the contact part 7 never spreads. For this reason, when assembling the buffering fixture 2a ₁ for packing, the force for joining and adhering the edge part of the buffering material 4 can be very small.
That is, when assembling the cushioning material 4 to the triangular cylinder body 3, it is only necessary to simply fix the contact portion 7 so that the ends 7a, 7a of the cushioning material 4 do not open naturally. What is necessary is just to fix the edge part of the buffer material 4 with the joining materials 5, such as a ding tape and a gummed tape.
Moreover, as a method of fixing the contact portion 7, in addition to the above-described method, it is possible to employ a method of joining the adhesive or the buffer material 4 by fitting them, but it takes time for assembly or disassembly. Further, it is necessary to provide a special structure for fitting or fitting, and the cost is eventually increased. Therefore, the bonding with the bonding material 5 such as an adhesive tape is the simplest, and sufficient stability can be expected.
When cardboard is used for the cushioning material 4 of the packing buffer fixture 2a ₁ , it is necessary to pay particular attention to the direction in which the convex portions of the flute (wavy paper) sandwiched between the liners (outer paper) are arranged. . Generally, the load resistance of corrugated cardboard is maximized when a load is applied in the flute and parallel directions. Therefore, when importance is attached to the load resistance in the vertical direction, it is desirable that the cut surfaces at the end portions 7a and 7a of the cushioning material 4 are perpendicular to the flute arrangement. On the other hand, when importance is attached to the load resistance in the left-right direction, it is desirable that the cut surfaces at the end portions 7a, 7a of the cushioning material 4 are parallel to the flute arrangement.

Returning to the description of the structure of the packing buffer fixture 2a ₁ again, as shown in FIG. 2 (a), the packaging buffer fixture 2a ₁ according to this embodiment, adjacent to the bottom surface 8 and the bottom 8 A continuous notch 6 is provided on two matching side surfaces.
By arranging the cutout portion 6 in this way, there is an effect that the buffering fixture 2a ₁ for packing can be straddled on the article to be packed 10a.
