Description

  The present invention relates to a packing case for packing a heavy product such as a large-sized copying machine, and more particularly to a packing case that unpacks a packing case packed with such a heavy article and takes out the heavy article.

  When unpacking a packaging case containing heavy items and taking out the copier, the large copier will be heavier and lifted by four to five people, pulling out the bottom plate, or moving the copier from the bottom plate . This work is difficult to perform with a small number of people, and there is a problem that the product may be damaged by falling the product.

Therefore, in Patent Document 1, as shown in FIG. 4 , a structure in which a folding block 206 b is provided on a column 206 a of a pallet 202 is proposed. The folding block 102 is formed as a movable support column obtained by dividing the support column 206, and the package is stored between the upper bottom plate 204 and the lower bottom plate 205, and is taken out and unfolded at the time of unpacking, so that the space between the upper surface of the pallet 202 and the floor surface is obtained. A slope can be formed. Therefore, an object to be packed with casters placed on a pallet can be rolled on the slope and lowered to the floor surface.

Moreover, in patent document 2, what unwinds the packing case comprised with the wooden frame and forms a slope between a pallet upper surface and a floor surface by one of the fallen case side walls is proposed. .
JP-A-8-282666 (FIG. 1) Japanese Utility Model Publication No. 5-3129 (FIG. 1)

  However, in the method of Patent Document 1, since the folding block is folded and stored in the pallet at the time of packing, it is difficult for the operator to notice that the folding block is present at the time of unpacking, and even if it is noticed, the folding block is bothered. It is cumbersome to put out and there is a possibility that it is not used. In addition, when the level difference from the floor surface to the pallet upper surface is large to some extent, the slope length is shortened, so that there is a problem that the bottom plate may not hit and be lowered smoothly depending on the size of the caster of the object to be packed.

  Moreover, in the method of patent document 2, although the slope length can be ensured long, since it is necessary to ensure the intensity | strength which can bear the weight of the to-be-packaged object, a wooden packaging case is required and compared with the thing made from paper. The weight increases, which is undesirable from the viewpoint of material cost and environment.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging case that can easily form a slope having a sufficient slope length and strength, and that can achieve weight reduction and material cost reduction. To do.

In order to achieve the above object, the present invention provides a bottom plate body in which struts are disposed at a predetermined interval between an upper bottom plate and a lower bottom plate, and a fork insertion space for a forklift is formed between the struts, and the upper bottom plate. Provided on the upper surface of the upper bottom plate to relieve the load load of the article to be packed, the upper case connected to the bottom plate body, and bendably provided on at least two sides of the periphery of the upper bottom plate. A packing case for packing an article to be packed in the upper case by raising the flap vertically and connecting between the lower part of the upper case and pivoting on the buffer plate. possess a slope which is housed folded inside the upper case supported, and a reinforcing member for reinforcing supporting slope on provided the floor to the slope, said reinforcing member along the slope And it is provided slidably Te.

  The packaging case of the present invention includes a slope that is pivotally supported by the buffer plate and is folded and stored in the upper case, and a reinforcing member that is provided in the slope and supports and reinforces the slope on the floor surface. Thus, a slope having a sufficient slope length and strength can be easily formed between the upper surface and the floor surface of the bottom plate body. For this reason, it can be lowered to the floor without lifting a heavy article. Furthermore, since the slope and the reinforcing member can be made of cardboard or other cardboard, the weight can be reduced and the material cost can be reduced.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  A first embodiment of the present invention will be described. FIG. 1 is an exploded perspective view of a packaging case according to the first embodiment of the present invention.

  The packing case 1 includes a bottom plate 2 formed in a skid structure and an upper case 3 connected to the bottom plate 2. The bottom plate body 2 is provided with three support columns 6 with a predetermined interval between an upper bottom plate 4 and a lower bottom plate 5 formed of corrugated cardboard sheets, and for inserting a forklift claw between the support columns 6. A fork insertion space is formed. Moreover, the support | pillar 6 itself also has a rectangular notch in two places, and the fork insertion space is formed also by the corresponding notch of the three support | pillars 6. FIG. Foldable flaps 7 are provided around each side of the bottom plate body 2 around the four sides of the upper bottom plate 4. In addition, the flap 7 does not need to be provided in the four circumferences (entire circumference) of the upper bottom board 4, and should just be provided in the at least two sides of the periphery.

On both sides of the upper surface of the upper bottom plate 4, there are provided a pair of buffer plates 12 that relieve the load load of the large-sized copying machine 10 that is an object to be packed on the upper bottom plate 4. The buffer plate 12 corresponds to the casters 15 provided in the front and rear on both sides of the bottom surface of the large-sized copying machine 10, and receives the casters 15 when unpacking so as to serve as a rolling path for the casters 15. It is provided extending in the depth direction.

A slope 13 made of cardboard or the like is pivotally supported at one end edge of each buffer plate 12 so as to be freely rotatable. Between the slope 13 and the buffer plate 12, the one edge of the buffer plate 12 is used as a rotation axis so that the slope 13 can rotate from a vertically standing state to a state where the slope 13 falls to the floor surface. The craft paper or the like is pasted, and the craft paper or the like is configured to serve as a hinge when the slope 13 rotates. The slope 13 is normally refracted vertically and stood and stored on the inner wall of the flap 7, and constitutes an inclined surface extending from the upper surface of the bottom plate body 2 to the floor surface by tilting to the floor surface by its own weight when unpacking. The slope 13 has a sufficient length so that a slope with a long slope length can be formed. The slope 13 is provided with a reinforcing member 14 which will be described later so as to be slidable along the slope 13.

  For example, as shown in FIG. 2, the reinforcing member 14 is configured as a lightweight block by stacking and bonding cardboard or other cardboard cut into a trapezoidal shape, and a rectangular parallelepiped so that one of the side surfaces of the rectangular parallelepiped becomes an inclined surface. And has a slit-like through hole 14a parallel to a vertical surface facing the slope. The reinforcing member 14 is slidably provided along the slope 13 by inserting the slope 13 through the through hole 14a.

  Such a slope structure may be provided only on one side of the bottom plate body 2, but another slope structure may be provided on the opposite side. Furthermore, one or two similar structures may be provided on a pair of sides orthogonal to this.

  At the time of packing, first, the large-sized copying machine 10 is placed on the upper bottom plate 4 and the cushioning material 11 made of styrene foam is applied to the top and bottom. The large-sized copying machine 10 is lifted one side at a time so that the caster 15 is placed on the lower cushioning material 11 and then the cushioning material 11 is inserted. Then, the upper case 3 is covered with the slope 13 standing vertically, and the upper lid 9 is placed thereon. Finally, the flap 7 is raised in the vertical direction, and the connector insertion holes 8 are provided at predetermined positions between the lower portion of the upper case 3 and the flap 7 and between the upper portion of the upper case 3 and the upper lid 9. Then, a packing case 1 is integrated by inserting and locking a joint (not shown). At the time of unpacking, the packing case 1 is disassembled in the reverse procedure to the above.

  Here, the slope 13 is refracted vertically during packaging and stood against the inner wall of the upper case 3, but when unpacked, it rotates by its own weight as shown by the arrow in FIG. And it is designed to tilt to the floor. Further, the reinforcing member 14 is positioned at the base end portion of the slope 13 in the gap between the side surface of the copying machine 10 and the inner wall of the upper case 3 at the time of packing, and serves as a cushioning material. As shown by the arrow in FIG. 3B, the slope 13 slides toward the tip end side of the slope 13 while contacting the one end edge portion of the upper bottom plate 4 as the slope 13 rotates.

  When the slope 13 reaches the horizontal position, as shown by an arrow in FIG. 3C, the slope 13 is slightly bent by its own weight with the one end edge portion of the upper bottom plate 4 as a fulcrum. At this time, the reinforcing member 14 is located at a position adjacent to the column 6, and the slope portion is in contact with the floor surface to become a column that supports the slope 13.

  As described above, a slope is formed from the upper surface of the bottom plate 2 to the floor surface, and the caster 15 of the copying machine 10 rolls and slides on the slope so that the copying machine 10 can be lowered to the floor surface. . Therefore, it is not necessary to lift the heavy copying machine 10 by a large number of people, and it is possible to reduce the number of workers at the ground contact site and improve workability.

  The present invention can be used for a packing case for packing heavy products such as a large-sized copying machine.
