Description

[Technical Field]

[0001] The present invention relates to a divider to be housed in a packaging box. [Background technology]

[0002] One type of cardboard partition that can be placed inside a packaging box is one that has a base plate that is placed on the bottom of the packaging box, and is configured so that part of the base plate is folded upward to create a wall section (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3198090 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described partition body, the wall portion is connected to the base plate via a folding line, and the wall portion is prone to collapse, which causes a problem that the contents inside the packaging box may push down the wall portion and move.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a partition body in which wall members that divide the inside of a packaging box are difficult to collapse. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides a partition body to be accommodated in a packaging box, the partition body comprising a base plate to be placed on the bottom surface of the packaging box and a wall member extending in the front-to-rear direction, the wall member being inserted into a slit formed in the base plate. The base plate is formed with a front plate portion, a vertical plate portion extending downward from the rear edge of the front plate portion, and a horizontal plate portion extending diagonally upward and rearward from the lower edge of the vertical plate portion.

[0007] In the partition of the present invention, the underlay plate is folded in a mountain and a valley to form a step portion formed by the front plate portion, the vertical plate portion, and the horizontal plate portion. When a force acts in the left-right direction on both sides of the wall member inserted into the slit of the underlay plate, the wall member is supported by the step portion of the underlay plate, making it difficult for the wall member to fall over.

[0008] In the above-mentioned partition body, a recessed portion recessed downward is formed in the upper edge portion of the wall member, and the vertical plate portion of the underlay plate is inserted into the recessed portion, so that when the vertical plate portion of the underlay plate is fixed to the wall member, the shape of the step portion can be stabilized.

[0009] In the above-mentioned partition body, it is preferable that the two slits are formed in the underlay plate at a distance in the front-to-rear direction, and the insertion portion formed between the two slits is inserted into a recess formed in the lower edge portion of the wall member. In this way, when the underlay plate is fixed to the wall member, the shape of the step portion can be stabilized. Furthermore, when the underlay plate attempts to move upward, the insertion portion of the underlay plate catches in the recess of the wall member, thereby preventing the underlay plate from coming off the wall member.

[0010] In the partition body, a support portion protruding forward is formed at the lower portion of the wall member, and the front plate portion of the underlay plate is placed on the upper edge of the support portion. If so, The front end of the wall member is prevented from moving upward by the front plate portion of the underlay plate, so that the wall member can be prevented from coming off the underlay plate.

[0011] Furthermore, when the front panel of the underlay plate is placed on the upper edge of the support part of the wall member and the insertion part of the underlay plate is inserted into the recess of the wall member, the up and down movement of the underlay plate can be prevented, thereby stabilizing the underlay plate and preventing it from coming off the wall member. [Effects of the Invention]

[0012] In the partition of the present invention, the wall members are supported by the stepped portions of the underlay plate, making the wall members less likely to tip over, thereby preventing the contents inside the packaging box from shifting. [Brief explanation of the drawings]

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the front, rear, left and right directions are set for the convenience of describing the packaging box of this embodiment, and do not limit the configuration or usage of the partition body.

[0015] As shown in Fig. 1, the partition 1 of this embodiment is accommodated in a packaging box 2. The packaging box 2 of this embodiment has a bottom plate 3 and front, rear, left and right side walls 4 that are raised from the edges of the bottom plate 3. The type of box that can accommodate the divider of the present invention is not limited. For example, it may be a packaging box with a lid plate on the opening on the top, or a tray-shaped packaging box with an open top.

[0016] The partition 1 includes an underlay plate 10 that is placed on the bottom surface of the packaging box 2, and a wall member 50 that extends in the front-to-rear direction. The partition 1 is formed by assembling the underlay plate 10 and the wall member 50, which are separate bodies (see FIG. 3).

[0017] As shown in Fig. 2, the underlay plate 10 is formed by mountain or valley folding a blank sheet S1 cut out from a cardboard sheet at each fold line. The wall member 50 is formed by mountain or valley folding a blank sheet S2 cut out from a cardboard sheet at each fold line. The blank sheets S1 and S2 shown in Fig. 2 are arranged so that the inner surfaces are visible. The fold lines of each blank sheet S1, S2 are creases (pressed creases) formed by linearly pressing the surface of each blank sheet S1, S2. Note that the creases may also be formed with intermittent notches. This makes it easier to fold each blank sheet S1, S2 at the crease lines. Alternatively, the folded lines may be formed by forming half-cut slits that cut only the surface of each blank sheet S1, S2, or by forming intermittent slits that penetrate each blank sheet S1, S2.

[0018] As shown in Fig. 1, the underlay plate 10 is a plate-like member that is fitted into the packaging box 2 and is placed on top of the bottom surface (upper surface of the bottom plate 3) of the packaging box 2. As shown in Fig. 4, the underlay plate 10 forms a double bottom at the bottom of the packaging box 2. Then, the contents P are placed on the upper surface of the underlay plate 10.

[0019] 1, the underlay plate 10 is formed with a front plate portion 11, a first vertical plate portion 12 connected to the front plate portion 11, a first horizontal plate portion 13 connected to the first vertical plate portion 12, a second vertical plate portion 14 connected to the first horizontal plate portion 13, and a second horizontal plate portion 15 connected to the second vertical plate portion 14. The underlay plate 10 also is formed with a front wall 16 connected to the front edge of the front plate portion 11 and a rear wall 17 connected to the rear edge of the second horizontal plate portion 15.

[0020] The front plate 11 is a strip-shaped portion extending in the left-right direction. When the divider 1 is placed in the packaging box 2, the front edge of the front plate 11 contacts the inner surface of the front side wall 4, and the left and right edges of the front plate 11 contact the inner surfaces of the left and right side walls 4, 4, respectively. 4, the front plate portion 11 is disposed above and spaced apart from the upper surface of the bottom plate 3. The front plate portion 11 is inclined obliquely upward from the front edge portion toward the rear so that the rear edge portion is disposed higher than the front edge portion.

[0021] As shown in Fig. 1, a front wall 16 is connected to the front edge of the front plate 11 via a folding line. The front wall 16 is formed in a strip shape along the front edge of the front plate 11. As shown in Fig. 4, the front wall 16 extends vertically downward from the front edge of the front plate 11. When the partition body 1 is housed in the packaging box 2 , the front wall 16 is placed on the inner surface of the front side wall 4 , and the lower edge of the front wall 16 contacts the upper surface of the bottom plate 3 .

[0022] As shown in Fig. 1, a first vertical plate portion 12 is connected to the rear edge portion of the front plate portion 11 via a fold line. The first vertical plate portion 12 is formed in a strip shape along the rear edge portion of the front plate portion 11. As shown in Fig. 4, the first vertical plate portion 12 extends downward from the rear edge portion of the front plate portion 11. The first vertical plate portion 12 is inclined so that the lower edge portion is positioned further rearward than the upper edge portion.

[0023] As shown in Fig. 1, left and right protrusions 18, 18 that protrude downward are formed on the lower edge of the first vertical plate portion 12. As shown in Fig. 2, the left and right protrusions 18, 18 are formed symmetrically on either side of the center of the underlay plate 10 in the left-right direction. The protruding portion 18 is a portion that is cut off from the first horizontal plate portion 13 when the first vertical plate portion 12 and the first horizontal plate portion 13 described below are folded from the blank sheet S1. As shown in FIG. 4, when the divider 1 is housed in the packaging box 2, the lower edge of the protruding portion 18 comes into contact with the upper surface of the bottom plate 3.

[0024] 1, a first horizontal plate portion 13 is connected to the lower edge portion of the first vertical plate portion 12 via a folding line. The first horizontal plate portion 13 is formed in a strip shape along the lower edge portion of the first vertical plate portion 12. As shown in Fig. 4, the first horizontal plate portion 13 extends rearward from the lower edge of the first vertical plate portion 12. The first horizontal plate portion 13 is inclined obliquely upward from the front edge portion toward the rear so that the rear edge portion is positioned higher than the front edge portion. The first horizontal plate portion 13 is configured to be inclined at approximately the same angle as the front plate portion 11. The length in the front-rear direction of the first horizontal plate portion 13 is approximately the same as the length in the front-rear direction of the front plate portion 11. When the partition body 1 is housed in the packaging box 2, the front plate portion 11 and the first horizontal plate portion 13 are positioned forward of the center of the packaging box 2 in the front-rear direction.

[0025] 1, a second vertical plate portion 14 is connected to the rear edge portion of the first horizontal plate portion 13 via a folding line. The second vertical plate portion 14 is formed in a strip shape along the rear edge portion of the first horizontal plate portion 13. As shown in Figure 4, the second vertical plate portion 14 extends downward from the rear edge of the first horizontal plate portion 13. The second vertical plate portion 14 is inclined so that its lower edge is positioned further rearward than its upper edge. The second vertical plate portion 14 is configured to be inclined at approximately the same angle as the first vertical plate portion 12. When the partition body 1 is housed in the packaging box 2, the lower edge of the second vertical plate portion 14 comes into contact with the upper surface of the bottom plate 3.

[0026] 1, a second horizontal plate portion 15 is connected to the lower edge of the second vertical plate portion 14 via a folding line. The second horizontal plate portion 15 is formed in a rectangular shape with the same length in the left-right direction as the second vertical plate portion 14. As shown in Figure 4, the second horizontal plate portion 15 extends rearward from the lower edge of the second vertical plate portion 14. The second horizontal plate portion 15 is inclined obliquely upward from the front edge toward the rear so that the rear edge is positioned higher than the front edge. The second horizontal plate portion 15 is configured to be inclined at approximately the same angle as the front plate portion 11 and the first horizontal plate portion 13. The length of the second horizontal plate portion 15 in the front-to-rear direction is formed to be greater than half the length of the interior of the packaging box 2 in the front-to-rear direction, and when the partition body 1 is housed in the packaging box 2, the front edge portion of the second horizontal plate portion 15 is positioned forward of the center portion in the front-to-rear direction of the interior of the packaging box 2. In addition, the front edge portion of the second horizontal plate portion 15 contacts the upper surface of the bottom plate 3.

[0027] As shown in Fig. 1, a rear wall 17 is connected to the rear edge of the second horizontal plate portion 15 via a folding line. The rear wall 17 is formed in a strip shape along the rear edge of the second horizontal plate portion 15. As shown in Fig. 4, the rear wall 17 extends vertically downward from the rear edge of the second horizontal plate portion 15. When the partition body 1 is housed in the packaging box 2 , the rear wall 17 is placed on the inner surface of the rear side wall 4 , and the lower edge of the rear wall 17 contacts the upper surface of the bottom plate 3 .

[0028] In the state of the blank sheet S1 shown in FIG. 2, the underlay plate 10 is formed so that its length in the front-to-rear direction (the length in the left-to-right direction in FIG. 2) is greater than the length in the front-to-rear direction inside the packaging box 2 shown in FIG. When the underlay plate 10 is placed inside the packaging box 2, the underlay plate 10 is folded in a mountain fold or a valley fold at each fold line to match the length in the front-to-rear direction with the length in the front-to-rear direction inside the packaging box 2. When the underlay plate 10 is placed inside the packaging box 2 in this state, the front wall 16 and the rear wall 17 contact the inner surfaces of the front and rear side walls 4, 4, respectively, restricting the length in the front-to-rear direction and maintaining the underlay plate 10 in a folded state.

[0029] When the underlay plate 10 is housed in the packaging box 2, a first step portion 20 is formed by the front plate portion 11, the first vertical plate portion 12, and the first horizontal plate portion 13, and a second step portion 20 is formed by the first horizontal plate portion 13, the second vertical plate portion 14, and the second horizontal plate portion 15.

[0030] As shown in Fig. 2, front and rear slits 31, 32 are formed in the center in the left-right direction (up-down direction in Fig. 2) of the underlay plate 10. Both slits 31, 32 are elongated through holes extending in the front-rear direction (left-right direction in Fig. 2). The front slit 31 is formed from the lower end of the first vertical plate portion 12 to the first horizontal plate portion 13, the second vertical plate portion 14, and the second horizontal plate portion 15. The front slit 31 extends rearward beyond the center of the second horizontal plate portion 15 in the fore-and-aft direction. The rear slit 32 is formed at a distance in the front-to-rear direction from the front slit 31. The rear slit 32 is formed from the rear part of the second horizontal plate portion 15 to the upper end part of the rear wall 17. As shown in FIG. 3, the area between the front and rear slits 31, 32 is an insertion portion 33 to be inserted into a recess 53 of a wall member 50, which will be described later.

[0031] 1, the wall member 50 extends in the front-rear direction and is a wall that divides the inside of the packaging box 2 into left and right sections. The wall member 50 is formed by folding a blank sheet S2 (see FIG. 2) in half along the fold line.

[0032] The wall member 50 is inserted into the front and rear slits 31, 32 of the underlay plate 10. The wall member 50 is assembled perpendicularly to the bottom plate 3 and the underlay plate 10 of the packaging box 2. The upper part of the wall member 50 stands perpendicular to the upper surface of the underlay plate 10, and the lower part of the wall member 50 protrudes perpendicular to the lower surface of the underlay plate 10. As shown in FIG. 4, when the divider 1 is placed inside the packaging box 2, the lower edge of the wall member 50 comes into contact with the upper surface (bottom surface) of the bottom plate 3.

[0033] A support portion 51 that protrudes further forward than the upper portion of the front edge portion is formed at the lower portion of the front edge portion of the wall member 50. In other words, the upper portion of the front edge portion of the wall member 50 is located rearward of the front edge portion of the support portion 51. The front plate 11 of the underlay plate 10 is placed on the upper edge of the support portion 51. The rear end of the upper edge of the support portion 51 is positioned higher than the front end. The rear end of the upper edge of the support portion 51 is positioned one step lower than the upper edge of the wall member 50 behind it. The front plate portion 11 is inclined along the upper edge of the support portion 51. The front edge of the support portion 51 is in contact with the rear surface of the front wall 16 of the underlay plate 10.

[0034] A recessed portion 52 that is recessed downward is formed in the upper edge portion of the wall member 50 (in this embodiment, the rear end portion of the upper edge portion of the support portion 51) (see FIG. 3). The first vertical plate portion 12 of the underlay plate 10 is inserted into the recessed portion 52. The lower end of the recessed portion 52 is positioned further rearward than the upper end. The first vertical plate portion 12 is inclined along the recessed portion 52.

[0035] As shown in Fig. 3, a recess 53 recessed upward is formed at the rear of the lower edge of the wall member 50. As shown in Fig. 1, the insertion portion 33 formed between the front and rear slits 31, 32 of the underlay plate 10 is inserted into the recess 53 of the wall member 50. The insertion portion 33 of the underlay plate 10 is fitted into the upper end of the recess 53. The upper edge (top edge) of the recess 53 is positioned so that the rear end is higher than the front end. The second horizontal plate portion 15 is inclined along the upper edge of the recess 53.

[0036] When assembling the partition 1 of this embodiment, the blank sheet S1 shown in Fig. 2 is mountain-folded and valley-folded at each fold line to form the underlay plate 10 shown in Fig. 3. Also, the blank sheet S2 shown in Fig. 2 is folded in half at the fold line to form the wall member 50 shown in Fig. 3.

[0037] 1, the wall member 50 is inserted into both slits 31 and 32 from above the underlay plate 10. At this time, the support portion 51 of the wall member 50 passes through the front slit 31 and is positioned below the front plate portion 11 of the underlay plate 10. In addition, the insertion portion 33 of the underlay plate 10 is inserted into the recess 53 of the wall member 50. In this way, the partition body 1 can be formed by assembling the wall member 50 vertically to the underlay plate 10.

[0038] When the partition body 1 of this embodiment is stored in the packaging box 2, as shown in Figure 4, the front wall 16 and rear wall 17 of the underlay plate 10 contact the inner surfaces of the front and rear side walls 4, 4, respectively, thereby restricting the length of the underlay plate 10 in the front-to-rear direction, and thereby maintaining the underlay plate 10 in a folded state. In addition, the lower edge of the front wall 16 of the underlay plate 10 abuts against the upper surface of the bottom plate 3, thereby supporting the front edge of the front plate portion 11 at a predetermined height, and the lower edge of the rear wall 17 of the underlay plate 10 abuts against the upper surface of the bottom plate 3, thereby supporting the rear edge of the second horizontal plate portion 15 at a predetermined height.

[0039] As shown in Fig. 1, the internal space of the partition 1 is divided into left and right halves by a wall member 50. In this embodiment, as shown in Fig. 4, three box-shaped contents P can be stored stacked vertically in one of the internal spaces of the packaging box 2 divided by the wall member 50. The contents P in the first level from the bottom are placed on the upper surface of the second horizontal plate portion 15, with the front end surface abutting the rear surface of the second vertical plate portion 14. The contents P in the second tier from the bottom are placed on top of the contents P in the first tier, with the front end surface abutting against the rear surface of the first vertical plate portion 12. The contents P in the third tier from the bottom are placed on top of the contents P in the second tier, with the front end surface abutting against the inner surface of the front side wall 4 of the packaging box 2. According to the partition 1 of this embodiment, three contents P can be stacked vertically and housed in the packaging box 2 with the upper contents P shifted forward relative to the lower contents P.

[0040] In the partition body 1 as described above, as shown in FIG. 1, the underlay plate 10 is folded in a mountain direction and a valley direction, and two step portions 20, 20 having concave and convex portions formed in the vertical direction are formed. When a force acts in the left and right direction on the left and right sides of the wall member 50, the wall member 50 is supported by the step portion 20 of the underlay plate 10, making it difficult for the wall member 50 to fall over, and the partition body 1 can prevent the contents P (see Figure 4) in the packaging box 2 from moving.

[0041] 4, in the partition body 1 of this embodiment, the first vertical plate portion 12 of the underlay plate 10 is inserted into the recessed portion 52 formed in the upper edge portion of the support portion 51 of the wall member 50. Also, in the partition body 1, the insertion portion 33 of the underlay plate 10 is inserted into the recessed portion 53 formed in the lower edge portion of the wall member 50. By fixing each part of the underlay plate 10 to the wall member 50 in this way, the shape of both step parts 20, 20 of the underlay plate 10 can be stabilized.

[0042] In the partition body 1 of this embodiment, when the front end of the wall member 50 attempts to move upward, the front panel portion 11 of the underlay plate 10 prevents the front end of the wall member 50 from moving upward, thereby preventing the wall member 50 from coming off the underlay plate 10.

[0043] In the partition body 1 of this embodiment, the front panel 11 of the underlay plate 10 is placed on the upper edge of the support part 51 of the wall member 50, and the insertion part 33 of the underlay plate 10 is inserted into the recess 53 of the wall member 50. This prevents the underlay plate 10 from moving in the vertical direction, stabilizing the underlay plate 10 and preventing it from coming off the wall member 50.

[0044] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate within the scope of the invention. In the partition body 1 of this embodiment, as shown in Figure 1, two step portions 20, 20 are formed on the underlay plate 10, but the number of step portions 20 is not limited and is set appropriately depending on the number of contents. Furthermore, the size and inclination angle of the front plate portion 11, the first vertical plate portion 12, the first horizontal plate portion 13, the second vertical plate portion 14 and the second horizontal plate portion 15 are not limited, but are set appropriately according to the shape of the contents.

[0045] In the partition body 1 of this embodiment, one wall member 50 is attached to the underlay plate 10, but there is no limitation on the number of wall members 50. For example, a plurality of slits may be formed in the underlay plate 10 in the left-right direction, and a plurality of wall members 50 may be attached to each slit.

[0046] Furthermore, the shape of the wall member 50 is not limited and is set appropriately depending on the shape of the contents. Furthermore, the wall member 50 of this embodiment is formed by folding a blank sheet S2 (see FIG. 2) in half, but the wall member 50 may also be formed from a single sheet.

[0047] In the partition 1 of this embodiment, the support portion 51 protrudes from the lower portion of the front edge of the wall member 50, and the front edge of the upper portion of the wall member 50 is located rearward of the front edge of the support portion 51. However, as in the partition 1A shown in FIG. 5, the front edge of the upper portion of the wall member 50 may be aligned with the front edge of the support portion 51. In this configuration, a recess is formed in the front edge of the wall member 50, and the front plate portion 11 of the underlay plate 10 is inserted into this recess. This makes it possible to prevent the front portion of the underlay plate 10 from moving up and down, thereby stabilizing the underlay plate 10 and preventing it from coming off the wall member 50.
