Description

  The present invention relates to a wrap-around type cardboard box, in particular, a cardboard box that is hard to collapse and tilt when the cardboard boxes are stacked, a method for stacking the cardboard boxes on a pallet, and a method for stacking the cardboard boxes on the pallet Related to the corrugated cardboard box.

  A cardboard box is used when a container containing food or the like is collectively delivered from a manufacturer to a store or retailer. The goods are then stored and stacked in trucks, wagons, etc., and transported to the destination. For this reason, load collapse may occur due to vibration or the like. Various methods have been conventionally used to prevent this.

  For example, Patent Document 1 has a top plate, a side plate, and a bottom plate. In a wrap-around type cardboard box in which a flap is connected to each side edge of the top plate, the side plate, and the bottom plate, the top plate is connected to the flap connecting portion of the top plate. In addition, a gate-type cut line is engraved to form a protrusion, and a bottom plate is disclosed in which a notch is formed at a position corresponding to each protrusion in which the containers are stacked. When stacked, stored and transported, protrusions formed on the top plate can be fitted into notches provided on the bottom plate to cope with vertical and horizontal vibrations, and load collapse can be reduced.

  Moreover, patent document 2 is disclosing what provided the convex guide and the recessed part in the packaging box. When this packaging box is assembled, the convex guide plays a role in positioning during stacking. The convex guide of the packaging box and the cut-out concave portion are stacked so as to fit each other. Thus, the collapse of the load is effectively prevented, and effects such as prevention of a decrease in the compressive strength due to the collapse of the load (20% to 80%) and a reduction in the damage of the product due to the collapse of the load are obtained.

  Furthermore, Patent Document 3 discloses that a part of corrugated paper, paperboard or the like is broken and raised to form an anti-slip buoyant part having a fitting end. A box is formed by arranging a large number of raised parts on the outer periphery of the top and bottom surfaces, and the mating ends of the raised parts face each other with mating ends on both sides that come into contact with each other when the boxes are stacked horizontally Thus, the anti-slip structure is characterized in that the end direction is set as described above. When the contents are put in this cardboard box and stacked, and this is transported, the cardboard box that is about to be displaced or dropped due to external factors such as vibration or other external forces such as vibration, Even if a force to try to slide acts due to the anti-slip structure, the slip can be prevented by a large frictional force that resists this force.

  Patent Document 4 discloses a package for a storage battery in which a hot melt adhesive is applied and cured in advance on the surface of a cardboard box. A coefficient of friction is increased by applying a hot-melt adhesive on the surface of the cardboard box in advance, and the coefficient of friction is increased, so that the cardboard box packed with storage batteries can be made less likely to collapse during stacking transportation. However, with the recent modal shift, a shift from trucking to freight car transportation is being attempted. For this reason, it is necessary to transfer the palletized cardboard boxes loaded on the truck at the factory to the wagons at the station, but the palletized cardboard boxes cannot be transferred to the wagons as they are. Therefore, it is necessary to unload the cardboard boxes loaded on the pallet from the pallet and reload them onto the wagon. Such a transshipment has a problem that the adhesive strength of the adhesive of the cardboard box is weakened and the collapse of the cargo easily occurs.

  Further, Patent Document 5 discloses a paper container having an anti-slip characteristic, in which an anti-slip layer mainly composed of a synthetic resin is formed on each outer surface of the side wall, the top board, and the bottom board in a paper container that serves as a top plate and a bottom plate. Is disclosed. Also disclosed is a paper container in which the anti-slip layer is partially formed on each outer surface of the side wall, top plate, and bottom plate of the container. Thereby, even when an external force is applied not only in the horizontal direction but also in the vertical direction to the stacked containers, it is possible to provide a container that is unlikely to cause a side slip or a jumping phenomenon.

The problem of collapsing during storage and transportation of cardboard boxes has conventionally occurred, and a great deal of labor and cost has occurred to restore the collapsing. On the other hand, as described above, conventionally, there have been various means for preventing the collapse of the stacked cardboards. The wrap-around cardboard box also has the prevention means described in Patent Document 1. However, in recent years, there is an urgent need in Japan for the creation of a recycling-oriented society and the establishment of a sustainable society due to environmental problems and resource depletion. Therefore, reducing the thickness of the corrugated cardboard box, reducing the volume and reducing the weight, achieving cost reduction, and examining the corrugated cardboard box and the method of stacking the corrugated cardboard box that can allow the strength to be reduced. There was a need to do. In other words, it is necessary to study a corrugated cardboard box that can reduce the strength deterioration of the cardboard box as much as possible even when the corrugated cardboard box whose strength has been reduced is stacked due to a decrease in the strength of the cardboard box, and a method of stacking the cardboard boxes. was there.
In particular, a wrap-land type corrugated cardboard has a glue-laminated flap that is bonded to the side surface by hot melt, but this glue-laminated flap has become shorter in order to save resources. And, when the box is assembled and glued by the machine, the distance between the fulcrum and the action point is shortened by the amount of the shortened flap, and the corners are not easily bent due to the repulsion of the top plate. For this reason, there is a problem that the swell is slightly swollen and the glued flap side becomes higher when the blocks are stacked, and the cardboard boxes are inclined, and the strength of the stacked cardboard boxes is deteriorated.

  Corrugated cardboard boxes have a great difference in strength that deteriorates during storage depending on how they are stacked. FIG. 8 on page 11 of “Design of Corrugated Cardboard Box” (Japan Packing Industry Federation, August 20, 2006, 4th edition) shows the deterioration of box compression strength due to the pallet stacking pattern. Alternating row stacking is a common stacking method, and by changing the orientation of even-numbered and odd-numbered cardboard boxes by 90 degrees, the collapse of cargo is prevented. However, the strength deterioration during storage is remarkable at 50%. The cardboard box exhibits the strongest strength in the case of block stacking, that is, when the force is received at the ridgeline. That is, the strength can be increased most by supporting the load at the four ridge lines, and the strength deterioration due to the stacking is as small as 20%. However, it is not common because it easily shakes and collapses. Therefore, there is a need for a method that can prevent the collapse of cargo during storage and movement in block stacking.

  An object of the present invention is to provide a wrap-around cardboard box that does not tilt even when stacked in blocks and is not easily collapsed. Another object of the present invention is to provide a wrap-around type cardboard box that hardly damages the bottom surface of the cardboard box when stacked alternately. Another object of the present invention is to provide a wrap-around cardboard box that is less likely to collapse. Another object of the present invention is to provide a wrap-around cardboard box suitable for preventing inclination when stacked in blocks. Another object of the present invention is to provide a corrugated cardboard box stacked on a pallet, and to provide a corrugated cardboard box stacking method.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Corresponding components are denoted by common reference symbols throughout the drawings.

  1 to 4, a wraparound cardboard box 1 according to an embodiment of the present invention forms a top plate 10, side plates 11 and 12, and a bottom plate 13, and the top plate 10, the side plates 11 and 12, and the bottom plate 13 are formed. Adhering flaps 18, 19, 20, and 21 to opposing side edges 14, 15, 16, and 17, and connecting them via a side edge 23 that faces a side edge 22 between the top plate 10 and the side plate 11. It has a flap 24. Further, at least one of the side edges 14, 22, 23 of the top plate 10 is engraved with at least one gate-shaped cutting line 25 toward the top plate 10, thereby forming a projection 26. Notches 27 are formed at locations corresponding to the protrusions 26 when the cardboard boxes are stacked. Thereby, when the cardboard boxes are stacked in blocks, the protrusions 26 and the notches 27 are fitted to each other, so that the collapse of the load can be prevented. In FIGS. 1 to 4, two cut lines 25 and protrusions 26 are provided on each side edge 14, and two cutouts 27 are provided on each side edge 17. However, the present invention is not limited to this.

  Furthermore, at least one side edge 14, 22, 23 on the top plate 10, at least one side edge 17 on the bottom plate 13, a side edge 28 between the side plate 11 and the bottom plate 13, and a side between the bottom plate 13 and the side plate 12. At least part of the vicinity of the edge 29 is broken and raised to dispose an anti-slip buoy 30 having a fitting end 30a, and when the fitting end 30a of the buoy 30 stacks cardboard boxes. The end directions are set so that the mating ends 30a, 30a on both sides that are in contact with each other face each other. Thereby, when the cardboard boxes are stacked in blocks, the fitting ends 30a on both sides are fitted, so that the collapse of the load can be prevented. 5 and 6 respectively show examples of enlarged views of the fitting end 30a of the top plate 10 and the fitting end 30a of the bottom plate 13 that are fitted when the cardboard boxes are stacked in blocks (the anti-slip floating portion). 30 and the specific aspect of the fitting end 30a are described in Patent Document 2 and will not be described in further detail. It is only necessary that the fitting ends 30a face each other, and FIGS. 5 and 6 are examples, and it is obvious that the fitting ends 30a are not limited to the fitting ends 30a of FIGS. Further, in order to prevent the collapse of the load, the anti-slip raised portion 30 is provided along at least one of the side edges 14, 22, 23 on the top plate 10 and the side edges 17, 28, It can also be arranged along at least one of 29.

Further, the length of the side plate 12 in contact with only the bottom plate 13 in the direction of the side edge 16 is shorter than the length of the other side plate 11 in the direction of the side edge 15. Currently, as described above, the size of the adhesive paste flap 24 is shortened to reduce the volume, but the size of the adhesive paste flap 24 is reduced from 50 mm to 30 to 40 mm, for example, 35 mm as an example (this) Can save a cardboard box of about 10 g), but since the length in the direction of the side edge 16 of the side plate 12 to which the glue-attached flap 24 is attached is short, when the cardboard box is assembled, the side plate 12 side is attached to the paste-attached flap 24. Due to the bulging, it is possible to prevent the height from being higher than the side edge 11 and to prevent the cardboard box from being inclined.
FIG. 7 shows a case where cardboard boxes having the same length b in the side edge 16 direction of the side plate 12 and the length a in the side edge 15 direction of the side plate 11 are stacked, and the length b in the side edge 16 direction of the side plate 12 It is a schematic diagram at the time of stacking cardboard boxes shorter than the length a in the direction of the side edge 15 of the other side plate 11. The former shows that the stacked cardboard boxes are inclined, while the latter shows that the stacked cardboard boxes are not inclined.

  Thus, according to the wrap-around type cardboard box of the embodiment of the present invention, even when the cardboard boxes are stacked in blocks, the cardboard box can be prevented from being inclined and collapsed. Play.

  Further, the height of the protrusion 26 can be made shorter than the length of the cutting line 25 in the direction of the side edge 23. Thereby, even if it is a case where a corrugated cardboard box is piled up alternately, damage to the bottom face of a corrugated cardboard box can be reduced by crushing a projection. Further, the height of the protrusion 26 is preferably about 1 to 10 mm. As a result, even when the cardboard boxes are stacked alternately, it is possible to provide a cardboard box suitable for reducing damage to the bottom surface of the cardboard box by collapsing the protrusions, and to produce cardboard boxes. In the meantime, the protrusion 26 can be prevented from being crushed in the production line. More preferably, the height of the protrusion 26 is 2 to 5 mm. As a result, when the cardboard boxes are stacked in blocks, the core of the bottom plate 13 of the cardboard box is crushed by its own weight, and the protrusions 26 bite into the cutouts 27, so that the fitting property can be improved.

  Further, the raised portions 30 can be disposed at at least one four corners of the top plate 10 of the cardboard box and at least one four corners of the bottom plate 13. Thus, when the cardboard boxes are stacked in blocks, the cardboard boxes can be collapsed with a small number of the raised parts 30 by disposing the raised parts 30 in at least a part of the four corners of the cardboard box where the load is most applied. Can be prevented. Of course, when the raised portions 30 are arranged at the four corners, it is clear that the collapse of the cardboard box can be prevented most.

  Furthermore, the end directions can be set so that the fitting ends 30a and 30a on both sides are oppositely fitted at 90 °. Thereby, since fitting end 30a, 30a fits reliably at 90 degrees, the load collapse of a cardboard box can further be prevented (refer FIG. 8 and 9).

  Further, the end directions can be set so that the fitting ends 30a and 30a on both sides are L-shaped and are oppositely fitted. As a result, the two L-shaped fitting ends 30a and 30a are fitted at 90 °, respectively, so that the collapse of the cardboard box can be further prevented (see FIGS. 10 and 11).

  Furthermore, the width | variety of the paste sticking flap 24 is 30-40 mm, The length of the side edge 16 direction of the side plate 12 can also be 1-3 mm shorter than the length of the side edge 15 direction of the other side plate 11. Thereby, it is possible to provide a wrap-around cardboard box suitable for preventing the cardboard box from being inclined when the blocks are stacked (see FIG. 7).

  As for the method of stacking the cardboard boxes on the pallet 31, the upper cardboard boxes can be stacked alternately, and the cardboard boxes other than the upper can be stacked by block stacking. Accordingly, a method for stacking cardboard boxes can be provided that increases the stability without tying the upper part with a string or the like (see FIG. 12). Furthermore, as can be seen from FIG. 12, the block stacking of the lower part of the cardboard boxes to be pallet 31 differs by 90 ° between the stacking method of the two cardboard boxes from the right and the stacking method of the two rows from the left. Can be. Further, as can be seen from FIG. 12, the alternating cardboard box stacking may be performed every two stages. Here, when the compressive strength test of alternating row stacking and block stacking was performed, it was found that the block stacking was about 1.6 times stronger than the alternating row stacking. As a result, according to the method of stacking according to the present invention, even if the liner of the cardboard box is reduced from 220 g (K220) to 170 g (K170) by basis weight, the liners having 220 g basis weight (K220) are alternately stacked. It turned out that the intensity | strength equal to or more than the case can be obtained. The following are the test results that serve as the basis.

First, Table 1 shows the result of compressive strength by the method of stacking cardboard boxes.

Next, Table 2 shows a strength deterioration comparison when corrugated cardboard boxes provided with raised portions, notches, and protrusions are alternately stacked.

Further, Table 3 shows a comparison of slip angles when the raised portion, the notch, and the protrusion are provided.

Table 4 shows a comparison of compressive strength (strain amount 10 mm) depending on the thickness of the cardboard box.

Further, Table 5 shows the amount of cardboard reduction, etc., depending on the cardboard thickness.

  Furthermore, ten cardboard boxes can be stacked on the pallet 31, the upper four stages can be stacked alternately, and the lower six stages can be stacked in blocks. Accordingly, it is possible to provide a method for stacking cardboard boxes suitable for increasing stability without tying the upper part with a string or the like.

  Further, the cardboard boxes stacked by the above-described method for stacking the cardboard boxes onto the pallet 31 can be provided. Thereby, even if it does not tie an upper part with a string etc., the cardboard box stacked on the pallet 31 which increases stability can be provided.
