Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the schematic structure of the suspended packaging box 1 will be described with reference to FIGS. 1 to 3 and the like.

As shown in FIGS. 1 to 3, the suspended packaging box 1 includes a hollow rectangular parallelepiped outer box body 2 and an inner tray body 3 capable of supporting a plurality of packaging packs P accommodating articles A in a suspended state. ing. In the outer box body 2, a plurality of stages (two stages in the embodiment) of the inner tray bodies 3 are stacked and housed.

Here, as the article A, fragile items such as strawberries, cherries, and eggs can be mentioned. The packaging pack P has a box-like shape that opens upward, and a flange Pf that surrounds the outer peripheral side of the opening is formed at the peripheral edge of the opening (see FIGS. 8 to 10). The packaging pack P was formed of, for example, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyvinyl acetate (PVA), polytetrafluoroethylene (PTFE), ABS resin, or the like. It is made of transparent resin.

With this configuration, when selling goods A directly from a general producer to consumers such as confectionery stores and restaurants, a predetermined number of packaging packs P containing goods A can be sold without using an expensive automatic packing machine. The suspended packaging box 1 containing the above can be easily mailed or delivered to home. If the total size of the three sides (width x depth x height) of the outer box 2 is set to a specified size suitable for mailing or home delivery, it is easy to estimate the cost of mailing or home delivery, and the consumer can also mail or deliver. It is convenient and easy to understand the delivery cost.

The outer box body 2 is formed of two corrugated cardboard sheets 4 (see FIG. 4). Therefore, the outer box body 2 can be easily disposed of. The outer box body 2 (corrugated cardboard paperboard 4) has a first side plate 5 and a second side plate 6. The first side plate 5 and the second side plate 6 are connected to each other via the vertical crease line 7. A glue margin portion 8 is formed on one of the short edge portions of the second side plate 6. The glue margin portion 8 of one corrugated board 4 is adhered to the short edge portion of the first side plate 5 of the other corrugated board 4 at a position facing the vertical crease line 7, and the glue margin 8 and the vertical fold are formed. By bending along the line of sight 7, a square tubular shape (four peripheral side plates 5 and 6) composed of a pair of first side plates 5 and a pair of second side plates 6 is formed.

A rectangular outer flap 10 is continuously provided at the longitudinal edges located above and below the first side plate 5 via the first horizontal crease line 9. At the longitudinal edges located above and below the second side plate 6, rectangular inner flaps 12 are continuously provided via the second horizontal crease line 11. By bending each inner flap 12 inward along the second horizontal crease line 11 and then bending each outer flap 10 inward along the first horizontal crease line 9, the inner flap 12 becomes the outer flap 10. The flaps 10 and 12 are overlapped on the upper and lower sides of the square cylinder-shaped four peripheral side plates 5 and 6 to close the opening. As a result, the top plate 13 and the bottom plate 14 of the outer box body 2 are formed, and the outer box body 2 becomes a hollow rectangular parallelepiped shape.

The top plate 13 of the outer box body 2 is provided with a window hole 15 for internal visibility. In the embodiment, a horizontally long cut-off portion 16 is formed on the tip edge of the upper outer flap 10. By closing both the upper outer flaps 10 and abutting the cut-off portions 16, a horizontally long window hole 15 is formed in the top plate 13 of the outer box body 2. Therefore, the state inside the outer box body 2 (the state of the article A and the packaging pack P) can be visually recognized through the window hole 15. The length of each of the upper inner flaps 12 in the lateral direction is set to a short length so as not to cover the window hole 15.

Vent holes 17 are provided in the four peripheral side plates 5 and 6 of the outer box body 2. Each side plate 5 or 6 is provided with a total of four ventilation holes 17 including two ventilation holes 17 corresponding to the upper inner tray body 3 and two ventilation holes 17 corresponding to the lower inner tray body 3. .. A grip hole 18 for carrying is provided on the upper side of each second side plate 6.

The inner tray body 3 that can be accommodated in the outer box body 2 is also formed of corrugated cardboard 4 like the outer box body 2 (see FIG. 5). Therefore, the disposal process of the inner tray body 3 can be easily performed in the same manner as the outer box body 2. The inner tray body 3 has a rectangular flat plate 19 and four peripheral side plates 20 and 21 connected to the flat plate 19 and is opened downward. A plurality of fitting holes 22 into which the packaging pack P is fitted are formed in a matrix on the flat plate 19. Each packaging pack P is supported in a suspended state by fitting the packaging pack P into each of the fitting holes 22 so that the flange Pf of the packaging pack P rests on the peripheral edge of the fitting hole 22.

With this configuration, the resin packaging pack P is suspended in the air when shipping and transporting not only strawberries but also fruits such as cherries, grapes, strawberries, loquats or plums, as well as fragile items A such as eggs and confectionery. Can be floated, stored and transported. Therefore, it is possible to reduce scratches and pain on the article A due to pressure on the bottom surface of the packaging pack P.

In the embodiment, a total of 10 fitting holes 22 in 2 rows and 5 columns are formed. Therefore, 10 packaging packs P can be accommodated in one inner tray body 3, and a total of 20 packs of 2 stages × 10 packs can be accommodated as one set as one suspended packaging box 1.

Of the four peripheral side plates 20 and 21 of the inner tray body 3, the pair of longitudinal side plates 20 facing each other have the first and second fold lines 23, which extend along the longitudinal direction of the flat plate 19 and the longitudinal side plates 20 and parallel to each other. 24 is formed so that the first fold line 23 is located closer to the flat plate 19. The first fold line 23 is a boundary line between the flat plate 19 and the longitudinal side plate 20.

Each longitudinal side plate 20 is divided into a first side plate portion 25 and a second side plate portion 26 located closer to the flat plate 19 with the second fold line 24 interposed therebetween. A plurality of locking projections 27 are formed on the tip edge of each second side plate portion 26. On the other hand, the flat plate 19 is formed with a notch groove 28 corresponding to each locking projection 27. In the embodiment, the cut groove 28 is formed in the short edge portion of the flat plate 19 near the first fold line 23 in the periphery of each fitting hole 22. Then, on the tip edge of each second side plate portion 26, the same number of locking projections 27 as the fitting holes 22 (5 in total, 10 in total) are formed so as to correspond to each notch groove 28. doing.

In the embodiment, the first side plate portion 25 is bent downward along the first fold line 23, the second side plate portion 26 is folded inward along the second fold line 24, and each locking projection 27 is formed on each of the flat plates 19. It is inserted into the notch groove 28 from below. In this way, the longitudinal side plates 20 facing each other in the inner tray body 3 have a triangular cross section, and more specifically, an inverted isosceles right triangle cross section (see FIG. 10), which is close to a two-sheet stacking state. It contributes to the improvement of the rigidity of the body 3. Further, since the longitudinal side plates 20 facing each other in the inner tray body 3 have high rigidity, the inner tray body 3 taken out from the outer box body 2 can be displayed with the packaging pack P group fitted therein. be.

A folding piece 30 protruding toward the fitting hole 22 is continuously provided on the short edge portion of the flat plate 19 near the first folding line 23 among the periphery of each fitting hole 22 via the folding line 29. .. In the embodiment, each cut groove 28 is formed in a substantially Ω shape, and a protruding portion 31 formed by the cut groove 28 is continuously provided in the folding piece 30. When the folding piece 30 is bent downward along the folding line 29, the rising portion 31 connected to the folding piece 30 stands up. Then, the locking projections 27 on the second side plate portion 26 side fitted in the cut groove 28 are brought into contact with each other so as to lean against each other. Therefore, it is difficult for the locking projection 27 to come out of the notch groove 28 due to the contact with the rising portion 31. Further, in the state where the packaging pack P is fitted in the fitting hole 22, the flange Pf of the packaging pack P is caught in the pair of the locking projection 27 and the rising portion 31. That is, the existence of the pair of the locking projection 27 and the rising portion 31 suppresses the displacement movement of the packaging pack P in the fitting hole 22.

A rectangular short side plate 21 is connected to each of the opposing short edge portions of the flat plate 19 via a perforated cut line 32. Each short side plate 21 is bent downward along the cut line 32. The presence of the cut line 32 makes it easier to bend and hold the short side plate 21 in a state substantially orthogonal to the flat plate 19.

The height dimension of each inner tray body 3 (which may be referred to as the height dimension of each side plate 20 and 21) is the bottom of the packaging pack P adjacent to the top and bottom in a state where the inner tray bodies 3 are stacked. The dimensions are set so that a gap can be left so that the article A does not come into contact with the article A.

Vent holes 17 are also provided in the four peripheral side plates 20 and 21 of the inner tray body 3. The longitudinal side plate 20 of the inner tray body 3 is provided with two ventilation holes 17 in the first side plate portion 25 and two ventilation holes 17 in the second side plate portion 26. The ventilation holes 17 of the first and second side plate portions 25 and 26, which are placed in a state close to two sheets, are in a positional relationship of communicating with each other. The short side plate 21 of the inner tray body 3 is provided with two ventilation holes 17. In the state where the two-stage inner tray body 3 is housed in the outer box body 2, the ventilation holes 17 groups are located at the corresponding positions of the side plates 5, 20 (6, 21) that overlap each other. Therefore, the inside and outside of the outer box body 2 and the inner tray body 3 communicate with each other by these 17 groups of ventilation holes, and the ventilation inside the suspended packaging box 1 can be improved.

A reinforcing plate 33 that supports the flat plate 19 is connected to a pair of short side plates 21 that face each other among the four peripheral side plates 20 and 21 of the inner tray body 3. In this case, a fitting groove 34 is formed on the central tip side of each short side plate 21, and each end portion of the reinforcing plate 33 in the longitudinal direction is fitted into each fitting groove 34 from below. The portion of the reinforcing plate 33 that protrudes outward from the short side plate 21 is bent so as to overlap the outer surface side of the short side plate 21. The upper end side of the reinforcing plate 33 comes into contact with the central frame portion 35 of the flat plate 19 from below. Even when the packaging pack P is fitted into each fitting hole 22, the reinforcing plate 33 stably supports the central frame portion 35 of the flat plate 19, so that the packaging pack P group is stably held. The reinforcing plate 33 is also provided with two ventilation holes 17 so as to correspond to the ventilation holes 17 provided in the longitudinal side plates 5 and 20 of the outer box body 2 and the inner tray body 3.

A handle hole 36 for taking out is provided at a position near each cut line 32 in the flat plate 19. By inserting the left and right hands into both handle holes 36 and pulling up the inner tray body 3, the inner tray body 3 can be easily taken out from the outer box body 2.
