  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. Note that, in all the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment)
First, the corrugated cardboard sheet 100 according to the first embodiment will be described with reference to FIGS. First, with reference to FIG. 1, the structure of the cardboard sheet | seat 100 which concerns on this embodiment is demonstrated. The corrugated cardboard sheet 100 according to the present embodiment can be assembled to the partition body 101 (see FIG. 5 and the like), and the assembled partition body 101 can assemble the cardboard case C (see FIG. 5 and the like) into six regions. It can be partitioned.

  FIG. 1 is a plan view of a corrugated cardboard sheet 100 according to the present embodiment. In the following, the front side surface of FIG. 1 is referred to as “front surface”, the back side surface of FIG. 1 is referred to as “rear surface”, and the case of folding into a valley when viewed from the front surface is referred to as “valley folding”. The case of folding into a mountain when viewed from the surface will be described as “mountain folding”. As shown in FIG. 1, a corrugated cardboard sheet 100 according to this embodiment includes two partition plates having a first end surface 5, a first intermediate surface 6, a central surface 7, a second intermediate surface 8, and a second end surface 9. 1, a first end connecting plate 2, a central connecting plate 3, and a second end connecting plate 4.

  As described above, the partition plate 1 has the first end surface 5, the first intermediate surface 6, the center surface 7, the second intermediate surface 8, and the second end surface 9, and is formed by being connected in this order. . Each of the surfaces 5 to 9 has a substantially rectangular shape, but a part of the outer side 10 of the first end surface 5 and a part of the outer side 11 of the second end surface 9 are slightly inclined inward. That is, the entire partition plate 1 is formed in a taper shape so that the width (the length in the connecting direction of the surfaces 5 to 9) becomes narrower toward the center of the corrugated cardboard sheet 100 (the side of the connecting plates 2 to 4). Yes. More specifically, the portion of the outer side 10 of the first end surface 5 that is away from the first end connecting plate 2 is parallel to the boundary lines 12 to 15 of the surfaces 5 to 9, but the first end The remaining portion near the connecting plate 2 is inclined so as to approach the first intermediate surface 6 as the first end connecting plate 2 is approached. In addition, the portion of the outer side 11 of the second end surface 9 that is away from the second end connecting plate 4 is parallel to the boundary lines 12 to 15 of the surfaces 5 to 9, but the second end connecting plate 4. The remaining portion close to is inclined so as to approach the second intermediate surface 8 as it approaches the second end connecting plate 4.

  The first end surface 5, the first intermediate surface 6, the center surface 7, the second intermediate surface 8, and the second end surface 9 have the same height (length in the direction perpendicular to the connecting direction), but the width. (Length in connecting direction) is different. Specifically, the first end face 5 and the second end face 9 have the same width, and the first intermediate face 6 and the second intermediate face 8 have the same width. The width of the central surface 7 is larger than the widths of the first end surface 5 and the second end surface 9 (the width of the widest portion) and smaller than the widths of the first intermediate surface 6 and the second intermediate surface 8.

  Moreover, the bending process is given to the boundary lines 12-15 of each surface 5-9 which comprises the partition plate 1. FIG. This bending process includes a slit S and ruled lines M and V. The slit S is formed near the center of the boundary lines 12 to 15 of the surfaces 5 to 9. Here, the “slit” refers to a cut formed so as to come out from the front surface to the back surface. In FIG. 1, the slit S is described so that the gap can be seen, but in reality, the gap is often not visible. The ruled lines M and V are formed on both sides of the slit S in the extending direction. The “ruled line” as used herein refers to a product in which depressions (grooves) are continuously formed on the front surface or the back surface, and is a process performed to facilitate folding in either direction (dentation on the side where the valley is to be folded). Form).

  Speaking of the partition plate 1 above the paper surface of FIG. 1, the boundary line 13 between the central surface 7 and the first intermediate surface 6 and the boundary line 14 between the central surface 7 and the second intermediate surface 8 are valley-folded ruled lines V (one-dot chain lines). Are formed on the boundary line 12 between the first intermediate surface 6 and the first end surface 5 and the boundary line 15 between the second intermediate surface 8 and the second end surface 9 (indicated by a dotted line). Display) is formed. Further, with respect to the partition plate 1 below the paper surface of FIG. 1, a mountain-fold ruled line M is formed at the boundary line 13 between the central surface 7 and the first intermediate surface 6 and at the boundary line 14 between the central surface 7 and the second intermediate surface 8. A valley-folded ruled line V is formed on the boundary line 12 between the first intermediate surface 6 and the first end surface 5 and the boundary line 15 between the second intermediate surface 8 and the second end surface 9. In this way, opposite ruled lines M and V are respectively formed on the boundary lines 12 to 15 of the two partition plates 1 (in one partition plate 1 folds to the boundary lines of two surfaces) In the other partition plate 1, a valley-folded ruled line V is formed at the boundary line between the two surfaces of the other partition plate 1).

  The first end connecting plate 2 is a plate that connects the first end surfaces 5 of the two partition plates 1. The first end connecting plate 2 has a long rectangular shape in the connecting direction with the first end face 5. Further, the boundary line 16 between the first end connecting plate 2 and the first end surface 5 is bent. Specifically, a slit S is formed near the center of the boundary line 16 between the first end connecting plate 2 and the first end surface 5, and a valley fold ruled line V (indicated by a one-dot chain line) on both sides in the extending direction of the slit S. Display) is formed.

  The central connecting plate 3 is a plate that connects the central surfaces 7 of the two partition plates 1. Both side edges 19 of the central connecting plate 3 are formed so that a part thereof extends from one central surface 7 toward the other central surface 7. If described using the mountain fold ruled line M and the valley fold ruled line V, the above-mentioned “one central plane 7” has the valley fold ruled line V formed on the boundary lines 13, 14 with the adjacent planes 6, 8. The above-mentioned “other central surface 7” is the central surface 7 in which mountain-folded ruled lines M are applied to the boundary lines 13, 14 with the adjacent surfaces 6, 8. Further, the boundary line 17 between the central connecting plate 3 and the central surface 7 is bent. Specifically, a slit S is formed in the vicinity of the center of the boundary line 17 between the central connecting plate 3 and the central surface 7, and valley-folded ruled lines V are formed on both sides in the extending direction of the slit S.

  The second end connecting plate 4 is a plate that connects the second end faces 9 of the two partition plates 1. The second end connecting plate 4 has a long rectangular shape in the connecting direction with the second end face 9. Further, the boundary line 18 between the second end connecting plate 4 and the second end surface 9 is bent. Specifically, a slit S is formed near the center of the boundary line 18 between the second end connecting plate 4 and the second end surface 9, and a valley fold ruled line V is formed on both sides in the extending direction of the slit S. Yes. In addition, each boundary line 16-18 of both the partition plates 1 and the other plates 2-4 is each formed so that it may be located on a straight line.

  The above is the configuration of the cardboard sheet 100 according to the present embodiment. Since all the boards 1-4 are connected, the corrugated board sheet 100 which concerns on this embodiment can be formed with one sheet. Therefore, even if a plurality of corrugated cardboard sheets 100 are stacked, the cardboard sheets 100 are stable and easy to handle during transportation. Further, the corrugated cardboard sheet 100 according to the present embodiment can be formed by pressing (cutting) one rectangular corrugated cardboard sheet. That is, the process which extracts between the center connection plate 3 and the 1st end connection plate 2, and between the center connection plate 3 and the 2nd end connection plate 4, the 1st end surface 5, the 2nd end surface 9, the 1st end connection plate 2 And the process which cuts the outer side of the 2nd end connection board 4, and the process which bends the boundary lines 12-18 of each surface 5-9 and each board 1-4 are once by press work (punching process). Therefore, the manufacturing cost can be reduced.

  Next, a method for assembling the partition body 101 from the corrugated cardboard sheet 100 according to this embodiment and a method for using the same will be described with reference to FIGS. 2-5 is the figure which showed the method of assembling the partition 101 from the corrugated-cardboard sheet 100 which concerns on this embodiment. First, as shown in FIG. 2, the boundary lines 16 to 18 of the plates 1 to 4 of the corrugated cardboard sheet 100 are valley-folded so that the surfaces of the two partition plates 1 face each other, and the two partitions The plate 1 is formed to be perpendicular to the first end connecting plate 2, the center connecting plate 3, and the second end connecting plate 4. 2 is in a state of being folded, and the cardboard sheet 100 shown in the lower portion of FIG. 2 is in a completely folded state. Also, the wavy lines near the upper and lower ends of each corrugated cardboard sheet 100 in FIG. 2 represent the edge surface (cut surface) of the corrugated cardboard sheet 100 (the same applies to FIGS. 3, 7 and 8). In addition, since the bending process including the ruled line V of valley fold is given to the boundary lines 16-18 of each board 1-4 as mentioned above, the valley in the boundary lines 16-18 of each board 1-4 Folding can be done easily.

  After that, as shown in FIG. 3, a force is applied in the direction of the arrow in FIG. 3, and among the boundary lines 12 to 15 of each surface 5 to 9, the boundary subjected to the bending process including the valley fold ruled line V Fold the line (see FIG. 1) into a valley and fold the boundary line (see FIG. 1), which includes the folding line M of the mountain fold, into the mountain, so that the partition plate 1 is centered on the central plane 7 It is formed in a convex shape. That is, the boundary lines 12 to 15 of the surfaces 5 to 9 are bent so that the center surface 7 becomes the tip of the protruding portion. When the boundary lines 12 to 15 of the surfaces 5 to 9 are bent according to the folding direction of the valley fold ruled line V and the mountain fold ruled line M in this way, the central surfaces 7 of the two partition plates 1 protrude in the same direction. Will do. At this time, the first end face 5 and the second end face 9 are positioned on the same plane, and the center plane 7 is positioned parallel to them. Furthermore, it forms so that the 1st intermediate surface 6 and the 2nd intermediate surface 8 may spread from the center surface 7 to connect.

  Here, in the above folding operation, it is not necessary to fold the two partition plates 1 separately. According to the corrugated cardboard sheet 100 according to the present embodiment, when one partition plate 1 is folded, the other partition plate 1 is folded. This is because the first end surfaces 5, the center surfaces 7, and the second end surfaces 9 of the two partition plates 1 are separated by the first end connection plate 2, the center connection plate 3, and the second end connection plate 4, respectively. This is because they are connected. Furthermore, since the first end faces 5, the center faces 7, and the second end faces 9 of the two partition plates 1 are connected to each other, the relative relationship between the surfaces 5 to 9 in the one partition plate 1. This is because, when the position is changed, the relative positions of the surfaces 5 to 9 in the other partition plate 1 are changed in the same manner. Therefore, according to the corrugated cardboard sheet 100 in the present embodiment, it is possible to simplify the operation of assembling the boundary lines 12 to 15 of the surfaces 5 to 9 (assembly operation), and to shorten the time of the assembly operation. .

  The reason why the side edges 19 of the central connecting plate 3 are formed so as to expand is to prevent the boundary lines 12 to 15 of the surfaces 5 to 9 from being bent in a wrong direction. In the case of this embodiment, if the operator is aware that the first intermediate surface 6 and the second intermediate surface 8 are bent along the side edge 19 of the central connecting plate 3, the boundary lines 13 and 14 on both sides are formed. In the central surface 7 on which the valley-folded ruled line V is formed, the boundary lines 13 and 14 on both sides can be folded without error. Thus, the assembly of the partition body 101 is completed.

  Thereafter, as shown in FIG. 4, the assembled partition body 101 is inserted into the cardboard case C from each of the connecting plates 2 to 4. At this time, the partition body 101 is set so that the width of the partition body 101 (the length from the outer side 10 of the first end surface 5 to the outer side 11 of the second end surface 9) is smaller than the corresponding width in the cardboard case C. Insert the cardboard case C in the contracted state. In addition, if the boundary line 13 between the central surface 7 and the first intermediate surface 6 and the boundary line 14 between the central surface 7 and the second intermediate surface 8 are bent so as to approach a right angle, the partition body 101 can be contracted. it can. Since the partition body 101 is made of the cardboard sheet 100 as described above, the partition body 101 has flexibility. When the partition body 101 is inserted into the cardboard case C in a contracted state, the partition body 101 expands inside and contacts the inner wall of the cardboard case C. Touch and stabilize. As described above, since the portions of the outer sides 10 and 11 of the first end surface 5 and the second end surface 9 are inclined inward, the partition body 101 can be inserted into the cardboard case C relatively easily. be able to.

  Thereafter, as shown in FIG. 5 (a plan view of the cardboard case C with the product A inserted), the product A (a bottle in this embodiment; a main body and a cap in FIG. 5) is divided into each region partitioned by the partition body 101. Is visible.) Insert. That is, as shown in FIG. 5, the inside of the cardboard case C is divided into six regions by the inner wall of the cardboard case C and the partition body 101, and the product A is inserted into each of these regions. The above is the method for assembling the partition body 101 from the corrugated cardboard sheet 100 according to the present embodiment and the method for using it. As described above, according to the corrugated cardboard sheet 100 of the present embodiment, the operation of assembling the boundary lines 12 to 15 of each surface 5 to 9 (assembly operation) can be simplified, and therefore the assembly operation is easily performed. be able to.

Moreover, as shown in FIG. 5, in the partition body 101 of this embodiment, the 1st intermediate surface 6 and the 2nd intermediate surface 8 are formed so that it may spread from the center surface 7 to connect. According to this configuration, the area is smaller than when the first intermediate surface 6 and the second intermediate surface 8 are parallel (when the first intermediate surface 6 and the second intermediate surface 8 are perpendicular to the central surface 7). The partition body 101 can be formed of the corrugated cardboard sheet. In the present embodiment, among the areas partitioned by the inner wall of the cardboard case C and the partition body 101, the upper left area in FIG. 5 is defined as a first area 21, and each area is clockwise from the first area 21. Assuming that the second to sixth regions 22 to 26 are used, it can be seen that the second region 22, the fourth region 24, and the sixth region 26 communicate with each other. However, if the product A to be inserted has a circular shape in plan view, such as a bottle shape or a can shape, the products A do not contact each other and sufficiently function as a partitioning body. be able to.
(Second Embodiment)
Next, a corrugated cardboard sheet 200 according to the second embodiment will be described with reference to FIGS. First, the configuration of the cardboard sheet 200 according to the present embodiment will be described with reference to FIG. FIG. 6 is a plan view of the cardboard sheet 200 according to the present embodiment. The corrugated cardboard sheet 200 according to the present embodiment has a first protruding portion 27 in which the first end connecting plate 2 protrudes toward the second end connecting plate 4, and the second connecting plate 4 is the first end connecting plate 2. The configuration differs from the corrugated cardboard sheet 100 according to the first embodiment in that the second projecting portion 28 projects to the side.

  More specifically, the first end connecting plate 2 has a first projecting portion 27 projecting toward the second end connecting plate 4, and the first projecting portion 27 is the first of the two partition plates 1. 1 between the intermediate surfaces 6. A part of the tip of the first protrusion 27 is linear and parallel to the boundary lines 12 to 15 of the surfaces 5 to 9. Further, the first projecting portion 27 is formed so as to be inclined toward the first intermediate surface 6 side (the lower side in the drawing of FIG. 6) where the mountain-fold ruled line M is formed at the boundary line 13 with the central surface 7. ing. Further, the first intermediate surface 6 has a shape in which a portion on the first projecting portion 27 side is cut out by the thickness of the corrugated cardboard sheet 200 as compared with the case of the first embodiment.

  Similarly, the second end connecting plate 4 has a second protruding portion 28 that protrudes toward the first end connecting plate 2, and this second protruding portion 28 is a second intermediate between the two partition plates 1. Located between the planes 8. A part of the tip of the second protruding portion 28 is linear and parallel to the boundary lines 12 to 15 of the surfaces 5 to 9. Further, the second projecting portion 28 is formed so as to be inclined toward the second intermediate surface 8 side (the lower side of the drawing in FIG. 6) where the mountain-fold ruled line M is formed at the boundary line 13 with the central surface 7. ing. Furthermore, the second intermediate surface 8 has a shape in which the portion on the second projecting portion 28 side is cut out by the thickness of the corrugated cardboard sheet 200 as compared with the case of the first embodiment.

  Next, a method for assembling the partition body 201 from the corrugated cardboard sheet 200 according to the present embodiment and a method for using the same will be described with reference to FIGS. 7-8 is the figure which showed the method of assembling the partition 201 from the corrugated-cardboard sheet 200 which concerns on this embodiment. First, similarly to the case shown in FIG. 2 of the first embodiment, as shown in FIG. 7, the boundary lines 16 to 18 of the plates 1 to 4 of the corrugated cardboard sheet 200 are valley-folded to form two partition plates 1. The two partition plates 1 are formed so as to be perpendicular to the first end connection plate 2, the central connection plate 3, and the second end connection plate 4. Since the boundary lines 16 to 18 of the respective plates 1 to 4 are bent including the ruled lines V of the valley folds, the valley folding at the boundary lines 16 to 18 of the respective plates 1 to 4 is easily performed. be able to.

  Thereafter, as shown in FIG. 8, a force is applied in the direction of the arrow in FIG. 8, and the boundary including the valley-folded ruled line V among the boundary lines 12 to 15 of each surface 5 to 9 is applied. Fold the line (see FIG. 6) into the valley and fold the boundary line (see FIG. 6) that includes the folding line M of the mountain fold into the mountain to project the partition plate 1 around the central plane 7 Form into shape. That is, the boundary lines 12 to 15 of the surfaces 5 to 9 are bent so that the center surface 7 becomes the tip of the protruding portion. When the boundary lines 12 to 15 of the surfaces 5 to 9 are bent according to the folding direction of the valley fold ruled line V and the mountain fold ruled line M in this way, the central surfaces 7 of the two partition plates 1 protrude in the same direction. Will do. At this time, the first protruding portion of the first end connecting plate and the second protruding portion of the second connecting plate are brought into contact with each other. As a result, the first intermediate surface 6 and the second intermediate surface 8 are connected so that the first end surface 5 and the second end surface 8 are positioned on the same plane, the central surface 7 is positioned in parallel with them. It forms so that it may spread from the center surface 7 to do.

  As described above, the portion of the first intermediate surface 6 on the side of the first protrusion 27 and the portion of the second intermediate surface 8 on the side of the second protrusion 28 are cut out by the thickness of the corrugated cardboard sheet 200. Since it has a shape, even when the corrugated cardboard sheet 200 is folded as shown in FIG. 8, the first projecting portion 27 and the first intermediate surface 6 do not come into contact with each other and are not deformed. 2 The projecting portion 28 and the second intermediate surface 8 are not brought into contact with each other to be deformed. Further, the central connecting plate 3 may be formed so that the first intermediate surface and the second intermediate surface are in contact with both side edges 19 when the first protrusion 27 and the second protrusion 28 are in contact. Good. Thus, the assembly of the partition body 201 is completed.

  Thereafter, as in the case of the first embodiment, the partition body 201 is inserted into the cardboard case (see FIG. 4), and the product is inserted into an area partitioned by the partition body 201 and the inner wall of the cardboard case (see FIG. 5). . As described above, the first protrusion 27 and the second protrusion 28 are inclined to one side. This is because the center of the region partitioned by the partition body 201 is considered to be shifted by the thickness of the cardboard sheet 200. That is, the first protrusion 27 and the second protrusion 28 come into contact with each other in a region corresponding to the fifth region 25 in FIG. 5, and the center of this region is the amount of the corrugated cardboard sheet 200 by the thickness of the cardboard case C. If the first projecting portion 27 and the second projecting portion 28 are not inclined toward the inner wall side, the portion where the first projecting portion 27 and the second projecting portion 28 abut is in this region. This is because the merchandise A inserted in the above-described region is inclined due to the deviation from the center.

  The above is the method for assembling the corrugated cardboard sheet 200 according to the present embodiment into the partition body 201 and the usage method. In the present embodiment, since the first projecting portion 27 and the second projecting portion 28 are in contact with each other in a state where the partition body 201 is formed, the partition body 201 is not further contracted from the completed state. The partition 201 can maintain its shape stably. Therefore, according to the present embodiment, it is effective when the shape of the partition 201 is required to be accurate, for example, when used in a packing process in which a product is inserted into a cardboard case by a mechanical device.
