  However, in Patent Document 1, when an impact such as dropping is applied in a state where a product such as an electronic device is stored in the product receiving recess, the partition plate is inserted by the partition plate although it is held between the upper and lower sides. Since it is not sufficient, the product may collide with the partition plate and the partition plate may come off from the insertion hole, and the product may exceed the partition plate.

  The present invention has been made in view of this point, and an object of the present invention is to make the packaging tray extremely easy to assemble and resistant to dropping and vibration.

In order to achieve the above object, in the first invention, a plurality of flat portions are formed vertically between the outer peripheral side walls by bending a single sheet a plurality of times,
Among the plurality of flat portions, a packaging tray in which a storage concave portion opened upward with a flat portion in the middle of the upper and lower sides as a bottom surface is an object.

And in the packaging tray,
On the bottom surface forming the storage recess, a straight insertion hole is formed,
A partition plate that is continuous from the upper edge of the storage recess and is folded inward to form one of the side surfaces of the storage recess;
A holding piece that is continuous with the bottom side of the partition plate, is folded further inward from the bottom side, overlaps with the upper and lower plane portions, and a tip abuts against the inner surface of the outer peripheral side wall;
An insertion protrusion that protrudes from a fold line at the bottom of the partition plate and is inserted into the insertion hole is formed.

  According to the above configuration, the partition plate continuous from the upper edge of the storage recess is folded inward, the bottom side of the partition plate is further folded, the insertion protrusion is projected from the fold line of the bottom side, and the fold line is continued. While the holding piece is overlapped with the upper and lower plane portions, the tip is brought into contact with the inner surface of the outer side wall, and the insertion protrusion is inserted into the insertion hole provided on the bottom surface of the storage recess. With this, the partition plate is firmly fixed, and even if force is applied to the partition plate in the direction of expanding the storage recess due to dropping or vibration in the state of packing the product, the holding piece is in contact with the inner surface of the side wall, The partition plate does not spread any further, and the insertion protrusion does not easily come off from the insertion hole. On the other hand, even if a force is applied in the direction of narrowing the storage recess, the force is distributed to the holding piece that contacts the bottom surface, so that the insertion protrusion cannot be easily removed from the insertion hole.

In the second invention, in the first invention,
A finger hook notch for hooking the fingertip is formed at the tip of the holding piece.

  According to the above configuration, the folding operation can be easily performed by hooking the fingertip to the finger notch when the partition plate and the holding piece continuous to the partition plate are folded inward.

In the third invention, in the first or second invention,
A plurality of sets of the insertion holes and the partition plates are provided in the storage recess.

  According to said structure, an assembly is easy also when a storage recessed part is not provided in the corner | angular part of an outer peripheral side wall, but an opposing side wall is made into a partition plate.

In a fourth invention, in any one of the first to third inventions,
A mobile phone is stored in the storage recess.

  That is, the mobile phone is packed not only with the mobile phone body but also with cables, electrical components, batteries, and the like, which are accessory parts. In particular, mobile phone bodies and battery packs having a large specific gravity are likely to exceed the partition plate due to external force caused by dropping or vibration, but the configuration of the present invention prevents the partition plate from coming off, so that the mobile phone can be easily transported. .

  As described above, according to the present invention, one sheet is bent a plurality of times, and the insertion protrusion on the bottom of the partition plate is inserted into the insertion hole provided on the bottom surface of the storage recess, and is continuous with the partition plate. The holding pieces were overlapped on the upper and lower flat portions, and the tips of the holding pieces were brought into contact with the inner surface of the outer side wall so as to securely fix the partition plate. For this reason, it is very easy to assemble, and a packaging tray that is strong against dropping and vibration can be obtained by the synergistic effect of the holding piece and the insertion protrusion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The packaging tray 1 is assembled into a rectangular parallelepiped shape by bending a single corrugated cardboard sheet 2 a plurality of times. Specifically, the packaging tray 1 includes first to fourth side walls 3, 4, 5, and 6 that surround the outer periphery, and first to third flat surface portions 7, 8, and 9 that are arranged vertically.

  The 1st side wall 3 and the 3rd side wall 5 block the width direction of the packaging tray 1, and are each equipped with the flap parts 3a and 5a for folding at the front-end | tip. The flap portions 3a and 5a can be bent at a width direction folding line 31 extending in the width direction of the packaging tray 1. The second side wall 4 is continuous with a third flat surface portion 9 constituting the bottom surface of the packaging tray 1, and the third flat surface portion 9 is provided with a flap portion 9a for gluing. The fourth side wall 6 is continuous with the second flat surface portion 8. A plurality of H-shaped slits 30 are formed between the second side wall 4 and the third flat surface portion 9, the third flat surface portion 9 and its flap portion 9a, and the fourth side wall 6 and the second flat surface portion 8 so as to be easily bent. Has been. A longitudinal fold line 32 extending in the longitudinal direction is formed where there is no slit 30.

  Among the first to third plane portions 7, 8, 9, a storage recess 10 is formed that opens upward with the second plane portion 8 in the middle between the upper and lower sides as a bottom surface. In the storage recess 10, the mobile phone body 50 is stored. That is, the second flat surface portion 8 has a raised bottom so that the mobile phone body 50 does not wobble in the stored state.

  A pair of linear insertion holes 11 are formed in parallel to each other in the second flat surface portion 8 forming the storage recess 10.

  A pair of partition plates 12 constituting the side surface of the storage recess 10 are formed at the upper edge of the storage recess 10 by folding inward. A holding piece 15 is continuously formed on the bottom side 12 a of the partition plate 12. As shown in FIG. 6, the holding piece 15 overlaps the second flat surface portion 8 by folding the partition plate 12 further inward with the bottom 12 a as a folding line, and the tip 15 a has the first side wall 3 or the third side wall. 5 is configured to be in contact with 5. A semicircular finger hooking notch 16 for hooking the fingertip is formed at the tip 15a of the holding piece 15.

  By folding the holding piece 15, a U-shaped slit is provided so that the insertion protrusion 13 protrudes from the bottom 12 a of the folding line. The insertion protrusion 13 is slightly narrower than the width of the insertion hole 11. Thus, when the partition plate 12 is bent along the widthwise folding line 31 of the upper edge of the storage recess 10 to form the side surface of the storage recess 10, the insertion protrusion 13 is inserted into the insertion hole 11 and comes off. It is configured to be stopped. In addition, the bottom side 12 a of the partition plate 12 is in contact with the second flat surface portion 8 in a state where the insertion protrusion 13 is inserted into the insertion hole 11.

  The concave portion longitudinal side wall 10a of the storage concave portion 10 continuous with the second flat portion 8 has the upright portion 10b cut into the lower end, and the tip of the upright portion 10b abuts on the third flat portion 9 when assembled. It is like that.

  The packaging tray 1 is provided with an accessory housing portion 20 in which cables, electrical components, batteries, and the like, which are accessory components, are packed in the storage recess 10. The bottom surface of the accessory housing portion 20 is constituted by the lowest third flat surface portion 9. The housing portion longitudinal side wall 20a of the accessory housing portion 20 is continuous with the recessed portion longitudinal side wall 10a via the glued portion 20b, and includes a pair of cut portions 20c at the lower end. Into the notch portion 20c, the accommodating portion width direction side wall 20d constituting the side wall of the accessory accommodating portion 20 is continuously inserted into the first flat surface portion 7 in an upright state bent at the width direction folding line 31. It has become.

-Assembly procedure of packing tray 1-
Next, the assembly procedure of the packaging tray 1 according to this embodiment will be described.

  First, the corrugated cardboard sheet 2 is cut out as shown in a development view shown in FIG. 3 to form a slit 30, a width direction folding line 31, and a longitudinal direction folding line 32. At this time, the insertion hole 11, the partition plate 12, the insertion protrusion 13, the standing portion 10 b, the cutting portion 20 c, and the like are also cut.

  Next, glue is applied to the fourth side wall 6 and the glued portion 20b.

  Next, the corrugated board sheet 2 is sequentially bent along the longitudinal folding line 32. Then, the 4th side wall 6 and the flap part 9a which apply | coated the glue are affixed, and the glued part 20b and the 1st plane part 7 back surface are affixed. In this state, the corrugated cardboard sheet 2 can be folded in the width direction. When the corrugated cardboard sheet 2 with the first to third flat surface portions 7, 8, 9 overlapped and transported to the product packaging place, the bulk is reduced and transported. It's easy to do.

  Next, the pair of partition plates 12 are folded inward along the widthwise folding curve 31. When the partition plate 12 is folded, the folding work is easily performed by hooking the fingertips on the finger hooking notches 16. First, the bottom side 12a of the partition plate 12 is bent and folded while the tip of the holding piece 15 is in sliding contact with the third flat surface portion 9. When the bottom side 12a is in sliding contact with the third flat surface portion 9, the partition plate 12 is held down. The insertion protrusion 13 is inserted into the insertion hole 11. Then, the holding piece 15 overlaps the second flat surface portion 8.

  Finally, the flap portion 3a of the first side wall 3 and the flap portion 5a of the third side wall 5 are inserted into the third flat surface portion 9 side to complete the assembly of the packaging tray 1. At this stage, as shown in FIG. 6, the inner surfaces of the first side wall 3 and the third side wall 5 abut against the tip of the holding piece 15, so that the holding piece 15 does not move further horizontally. In this way, even if the partition plate 12 is firmly held and an external force is applied by dropping or vibration in a state where the product is packed, the insertion protrusion 13 is not easily detached from the insertion hole 11.

  In this state, as shown in FIG. 4, the mobile phone body 50 is inserted into the storage recess 10 and the accessory is stored in the accessory storage unit 20. After that, as shown in FIG. 5, it inserts in the outer box 51, folds the 1st flap part 51a of the outer box 51, accommodates the instruction manual 52 etc., and covers with the 2nd flap part 51b. The mobile phone packaging work is completed.

  At this time, the mobile phone having a large specific gravity, such as the mobile phone main body 50, easily receives an external force due to dropping or vibration and gives an impact to the partition plate 12. Since the holding piece 15 is in contact with the inner surface of the third side wall 5, the partition plate 12 does not further spread, and the insertion protrusion 13 does not easily come off from the insertion hole 11. Conversely, even if a force is applied in the direction of narrowing the storage recess 10, the force is distributed to the holding piece 15 that abuts the bottom surface (second flat portion 8), so that the insertion protrusion 13 extends from the insertion hole 11. Does not come off easily. For this reason, since the mobile phone main body 50 does not wobble in the housing recess 10, the mobile phone or the like can be easily transported.

-Effect of the embodiment-
Therefore, according to the packaging tray 1 according to the present embodiment, one cardboard sheet 2 is bent a plurality of times, and the insertion protrusion of the bottom 12a of the partition plate 12 is inserted into the insertion hole 11 provided in the bottom surface of the storage recess 10. 13 is inserted, the holding piece 15 continuing to the partition plate 12 is overlapped on the second flat surface portion 8, and the tip 15a is brought into contact with the first side wall 3 or the third side wall 5, thereby securely fixing the partition plate 12. I did it. For this reason, the packaging tray 1 that is extremely easy to assemble and that is resistant to dropping and vibration can be obtained by the synergistic effect of the holding piece 15 and the insertion protrusion 13.
