Description

  The present invention relates to a buffer partition member for separating and storing a plurality of products and the like, and a packaging box using the same.

  Conventionally, as disclosed in, for example, Patent Document 1, a rectangular corrugated cardboard is bent to create a main body portion having a wall portion on both sides and a partition portion in the center, and a partition plate in the center of the wall portion and the partition portion. There was a collective packaging box in which side portions were inserted and engaged on both the left and right sides of the wall portion and the partition portion, and four accommodating portions were formed inside.

  This type of buffer partition member is often packed in multiple stages in an outer box after containing goods etc., and the lower buffer partition member is loaded from above, There exists a problem that a part (part distant from four corners of an outer wall) tends to be distorted. In this regard, in the collective packaging box of Patent Document 1, the partition plate and the side portion are engaged with the wall portion or the partition portion in a cross shape so that the intersection portions are dispersedly formed at a plurality of locations. On the other hand, the central part is effectively reinforced, and it is difficult to be dented or damaged.

Thus, the outer plate 24 and the inner plate 28 (1) stand substantially perpendicular to the connecting plate 26 and are fixed to face each other. This completes the assembly, and the main body 12 is assembled as shown in FIG.

  In this assembled state, the pair of inner plates 28 (1) and 28 (2) stand and overlap each other, and the pair of inner plates 32 (1) and 32 (2) also stand and overlap each other to form the inner wall NH. . The outer plates 24 and 36 stand up at the same height as the inner wall NH and become part of the outer wall GH. The connecting plates 26, 30, and 34 become the bottom plate B, respectively. Also, the pair of connecting pieces 54 and 58, the connecting pieces 60 and 62, the connecting pieces 56 and 64, the connecting pieces 78 and 82, the connecting pieces 84 and 86, and the connecting pieces 80 and 88, which are engaged with each other, It becomes a part of the outer wall GH.

As a result, the assembly is completed, and the buffer partition member 10 shown in FIG. 1 is assembled.

  In this assembled state, the auxiliary member 14 (1) has the auxiliary connecting plate 122 standing at the same height as the outer wall GH and overlapping the outside of the outer wall GH (outer plate 24). 2) stands on the upper surface of the bottom plate B (connection plates 26, 30) at the same height as the inner wall NH, further partitions the inside of the housing, and faces the inner wall NH and the outer wall GH facing each other with the bottom plate B (connection plate 26) interposed therebetween.

Similarly, in the auxiliary member 14 (2), the auxiliary connecting plate 122 stands up to the same height as the outer wall GH and overlaps the outer side of the outer wall GH (outer plate 36), and the two partition plates 120 (1), (2). Stands on the upper surface of the bottom plate B (the connection plates 30 and 34) at the same height as the inner wall NH, further partitions the interior of the housing, and connects the inner wall NH and the outer wall GH facing each other across the bottom plate B (the connection plate 34). Connect to

  Since the main crease line is provided at right angles to the length direction of the center core 20a of the substrate, the main body 12 has a corrugated cross section of the center core 20a at the upper end portions of the outer plates 24 and 36 serving as the outer walls GH. The end surface where the core 20a corrugated section can be seen is also formed at the upper and lower ends of each connecting piece that becomes the outer wall GH.

  Further, the cuts 102, 104, 106, 108, 110, 112, 114, 116 provided in the main body 12 are arranged as shown in FIGS. 5A and 5B, and the outer plates 24, 36 that become the outer walls GH. At the lower end portion of the, an end face through which the corrugated cross section of the core 20a can be seen is formed by the cut lines 102 and 116. Similarly, the upper and lower ends of the inner plates 28 (1), 28 (2), 32 (1), and 32 (2) serving as the inner wall NH are also inserted by the cut lines 104, 106, 108, 110, 112, and 114. An end face where the corrugated cross section of the core 20a can be seen is formed.

  After that, the assembled buffer partition member 10 is put in a separately assembled outer box 18 and a container (not shown) such as a product is set in each housing portion, and a new buffer partition member 10 is stacked on the upper surface. Place and store items (not shown) such as commodities in each storage unit. Thus, the state shown in FIG. 6 is obtained. The size of the outer box 18 is set to be the same as or slightly larger than that of the buffer partition member 10, and the outer surface of the outer wall GH of the buffer partition member 10 is the outer box 18 in a state where the buffer partition member 10 is accommodated in the outer box 18. Locked to the side surface 18a. Then, the packaging is finished by closing the canopy of the outer box 18, and the goods and the like are shipped in the packaging box 16.

  According to the buffer partition member 10 of the first embodiment, since there is no member protruding from the outer surface of the outer wall GH of the main body 12, the outer shape can be made more compact than before.

  In addition, it has a feature that it can obtain strength higher than the conventional one and is not easily crushed even if it is stacked in multiple stages. For example, at the portion where the inner plate (inner plate 28 (1), etc.) and the connecting piece (connecting piece 58, etc.) intersect, one base material is bent and continuous, so that different base materials are crossed. The strength against the load from above is higher than the conventional structure that intersects. In addition, the inner wall NH formed by the inner plate (inner plate 28 (1) and the like) and the outer wall GH formed by the connecting piece (the connecting piece 58 and the like) are formed by one sheet because the base material overlaps two sheets. It is stronger than it is. Further, as shown in FIGS. 5 (a) and 5 (b), at the upper end of each outer plate (outer plate 24, etc.) to be the outer wall GH and each inner plate (inner plate 28 (1), etc.) to be the inner wall NH. Since it has a structure in which the end face where the corrugated section of the core 20a can be seen is formed, a load from above can be firmly received at each end face, and the strength of the outer wall GH and the inner wall NH is further increased.

  Further, the partition plates 120 (1) and 120 (2) of the auxiliary members 14 (1) and 14 (2) are provided on the upper surface of the bottom plate B (the connecting plate 26 and the like) on the inner wall NH made of the inner plate 28 (1) and the like. Therefore, the partition plates 120 (1) and 120 (2) also act in the same manner as the inner wall NH, and an effect of further increasing the strength against the load from above is obtained. Further, in the portion of the outer wall GH formed by the outer plates 24 and 36, the auxiliary connecting plate 122 of the auxiliary member 118 stands up at the same height as the outer wall GH and overlaps the outside, so that the outer wall GH is further reinforced.

  When sufficient strength is obtained only by the structure of the main body 12, the partition plates 120 (1) and 120 (2) are not necessarily provided on the upper surface of the bottom plate B (the connecting plate 26, etc.). ) Etc.), it is not necessary to have a structure that stands up to the same height as the above, and a structure that simply divides the inside of the accommodating portion may be used. Similarly, the auxiliary connecting plate 122 does not necessarily have to have a structure that stands up to the same height as the outer wall GH. For example, it is important to facilitate the operation of attaching the auxiliary member 14 to the main body 12, and to use other structures. You may change to

  Further, according to the packaging box 16 of the first embodiment, an excellent buffering effect can be obtained by installing the buffer partition members 10 in one or more stages in the existing outer box 18 having no partition. It is possible to easily obtain a box with a partition having the above.

  The buffer partition member 10 can be used alone without being accommodated in the outer box 18. When the buffer partition member 10 is handled only by the main body 12, the main crease lines 42 and 48 are bent or stretched to change the shape, but the shape is fixed by attaching the auxiliary member 14. When the buffer partition members 10 are stacked in a plurality of stages, the convex portions 122a of the lower auxiliary connection plate 122 engage with the concave portions 122b of the upper auxiliary connection plate 122, and the upper buffer partition member 10 is positioned. Therefore, if it has a certain number of stages, it can be stacked stably. Therefore, the buffer partition member 10 can be used without any problem without the outer box 18.

  Next, 2nd embodiment of the buffer partition member of this invention and a packaging box using the same is described based on FIGS. Here, the same configurations as those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 7, the buffer partition member 130 of this embodiment includes a plurality of accommodating portions partitioned from each other, and is a tray-shaped member whose size is about 1/3 of the buffer partition member 10 described above. Only the main body 12 is formed. Moreover, the packaging box 132 of this embodiment is a box with a partition formed by installing the buffer partition member 130 in a separately prepared outer box 134. As for the buffer partition member 130, the main body 12 becomes the buffer partition member 130 as it is.

  As with the main body 12 of the buffer partition member 10, the buffer partition member 130 closes the outer wall GH that surrounds the four sides, the inner wall NH that partitions the inside of the outer wall to form a plurality of storage portions, and the lower surface of each storage portion. And a bottom plate B. The buffer partition member 130 is formed by three-dimensionally assembling a single cardboard sheet 136 (having a core 136a having a corrugated cross section) formed by punching a cardboard blank.

  As shown in FIGS. 8A and 8B, the configuration of the corrugated cardboard sheet 136 is similar to that of the corrugated cardboard sheet 20, except for the outer plates 24, 36 and the inner plates 28 (1), 28. (2), 32 (1), 32 (2) and the width of the connecting plates 26, 30, 34 are shortened to about 1/3. Further, the outer wall slits 24a, 24b, 36a, 36b and the slit-shaped through holes 28a, 28b, 32a, 32b are omitted, and the number of the cuts 102, 104, 106, 108, 110, 112, 114, 116 is 1 respectively. It is one by one.

  The assembly method of the buffer partition member 130 is the same as the assembly method of the main body 12 of the buffer partition member 10.

  In the assembled state shown in FIG. 7, the buffer partition member 130 stands with the pair of inner plates 28 (1), 28 (2) overlapping each other, and the pair of inner plates 32 (1), 32 (2) also overlap each other. Stand up to become the inner wall NH. The outer plates 24 and 36 stand up at the same height as the inner wall NH and become part of the outer wall GH. The connecting plates 26, 30, and 34 become the bottom plate B, respectively. Also, the pair of connecting pieces 54 and 58, the connecting pieces 60 and 62, the connecting pieces 56 and 64, the connecting pieces 78 and 82, the connecting pieces 84 and 86, and the connecting pieces 80 and 88, which are engaged with each other, It becomes a part of the outer wall GH. The configurations of the inner wall NH, the outer wall GH, and the bottom plate B are the same as those of the main body 12 of the buffer partition member 10.

  After that, the assembled buffer partition member 130 is put into a separately assembled outer box 134, and a container (not shown) such as a product is set in each storage unit, and a new buffer partition member 130 is stacked on the upper surface. Place and store items (not shown) such as commodities in each storage unit. Thus, the state shown in FIG. 9 is obtained. The size of the outer box 134 is set to be the same as or slightly larger than the buffer partition member 130, and the outer surface of the outer wall GH of the buffer partition member 130 is the outer box 134 in a state where the buffer partition member 130 is accommodated in the outer box 134. Locked to the side surface 134a. Then, the packaging is finished by closing the canopy of the outer box 134, and the product or the like is shipped in the packaging box 132.

  The buffer partition member 130 of the second embodiment is suitable when the floor area is relatively small, can obtain substantially the same effect as the buffer partition member 10 described above, and has one component member (corrugated cardboard sheet). 136 only).

  Further, according to the packaging box 132 of the second embodiment, an excellent buffering effect can be obtained by installing the buffer partition member 130 in one or more stages in the existing outer box 134 having no partition. It is possible to easily obtain a box with a partition having the above.

  When the buffer partition member 130 is handled alone, the main crease lines 42 and 48 are bent or stretched to change the shape. Therefore, the buffer partition member 130 is accommodated in the outer box to stabilize the shape, and is handled integrally with the outer box 134. It is preferable. However, if the shape can be changed by another method, it can be used without the outer box 134.

  In addition, the buffer partition member of this invention and a packaging box using the same are not limited to the said embodiment. For example, the structure of the engaging portion of the connecting piece (eg, the engaging portion 54a of the connecting piece 54) is an example, and two corresponding connecting pieces are integrally overlapped to form a part of the outer wall GH in the assembled state. If possible, it may be changed to another structure. The auxiliary members 14 (1) and 14 (2) may be formed of a single member and may be formed in a square shape and provided in the main body 12.

  In the case of the buffer partition members 10 and 130 described above, two inner walls NH formed of a pair of inner plates are provided, but the number of inner walls NH can be increased or decreased in accordance with the number of accommodating portions. In particular, when configuring a large buffer partition member having a large number of accommodating portions, it is preferable to increase the number of inner walls NH in order to increase the strength. If there is no concern about the strength, the number of accommodating portions may be simply increased by increasing the number of auxiliary members. In this case, the number of outer wall slits and inner wall slits of the main body is increased in accordance with the number of auxiliary members.

  The length and number of cuts (cuts 102, etc.) can be changed as appropriate. However, it should be noted that if the individual length is too long or the number is too large, the part of the main crease line (main crease line 38, etc.) is difficult to break during assembly. If the strength of the outer wall GH and the inner wall NH with respect to the load is sufficient, the cut may be omitted.

  The outer box in which the buffer partition member is put may be a box having at least a bottom surface and a side surface, and the canopy may be omitted. The size of the outer box may be a size that allows a plurality of buffer partition members to be aligned on the bottom surface.
