In the outer box body 2, the inner tray bodies 3 are stacked and accommodated in a plurality of stages (two stages in the embodiment).

Here, examples of the article A include fragile items such as strawberries, cherries, and eggs. 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 is made 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 such a configuration, when a general production farm sells the article A directly to a consumer such as a confectionery store or a restaurant, without using an expensive automatic packing machine, a predetermined number of the packaging packs P containing the articles A. It is possible to easily mail or home-deliver the airborne packaging box 1 containing the. If the total size of the three sides (width x depth x height) of the outer box body 2 is set to a prescribed size suitable for mailing or home delivery, it is easy to assume the cost of mailing or home delivery, and it is possible for customers to mail or It is easy and convenient to understand the delivery cost.

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

A rectangular outer flap 10 is continuously provided on the upper and lower longitudinal edges of the first side plate 5 via a first lateral fold line 9. A rectangular inner flap 12 is continuously provided on the upper and lower longitudinal edges of the second side plate 6 via a second lateral fold line 11. By folding each inner flap 12 inward along the second lateral fold line 11 and then folding each outer flap 10 inward along the first lateral fold line 9, the inner flap 12 becomes the outer flap 10. The flaps 10 and 12 are covered and the upper and lower sides of the four side plates 5 and 6 in the shape of a square tube are overlapped with each other 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 has a hollow rectangular parallelepiped shape.

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

Ventilation holes 17 are provided in the four side plates 5 and 6 of the outer box body 2. Each of the side plates 5 and 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.

Similarly to the outer box body 2, the inner tray body 3 that can be housed in the outer box body 2 is also formed by the corrugated paperboard 4 (see FIG. 5 ). Therefore, the disposal processing of the inner tray body 3 can be easily performed as with 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 open downward. On the flat plate 19, a plurality of fitting holes 22 into which the packaging pack P is fitted are formed in a matrix. The respective packaging packs P are supported in a suspended state by fitting the packaging packs P into the respective fitting holes 22 so that the flanges Pf of the packaging packs P are placed on the peripheral portions of the fitting holes 22.

With this configuration, when not only strawberry but also fruits such as cherries, grapes, figs, loquats or plums, as well as fragile articles A such as eggs and confectioneries are shipped and transported, the resin packaging pack P is suspended. Can be floated and stored for transportation. Therefore, it is possible to reduce the damage and pain of the article A due to the pressure on the bottom surface of the packaging pack P.

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

Among the four circumferential side plates 20, 21 of the inner tray body 3, the pair of opposing long side plates 20 have first and second fold lines 23 extending along the longitudinal direction of the flat plate 19 and the long 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 long 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 near the flat plate 19 with the second fold line 24 interposed therebetween. A plurality of locking protrusions 27 are formed on the tip edge of each second side plate portion 26. On the other hand, the flat plate 19 has cut grooves 28 corresponding to the respective locking projections 27. In the embodiment, the cut groove 28 is formed in the short edge of the flat plate 19 around each fitting hole 22 near the first fold line 23. Then, the same number of locking projections 27 as the fitting holes 22 (a total of 10 in the embodiment, 5 pieces in total) are formed on the tip edge of each second side plate portion 26 so as to correspond to each cut 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 back inside along the second fold line 24, and each locking projection 27 is attached to each flat plate 19. It is inserted into the cut groove 28 from below. As described above, since the longitudinal side plates 20 facing each other in the inner tray body 3 have a triangular cross section, more specifically, an inverted isosceles triangular cross section (see FIG. 10) close to a two-ply state, the inner tray is Contributes to improving 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 still fitted therein. is there.

Out of the periphery of each fitting hole 22 in the flat plate 19, a folding piece 30 protruding toward the fitting hole 22 is continuously provided at a short edge portion near the first fold line 23 via a folding line 29. .. In the embodiment, each cut groove 28 is formed in a substantially Ω shape, and the protrusion-shaped rising portion 31 formed by the cut groove 28 is continuously provided to the folding piece 30. When the folding piece 30 is bent downward along the folding line 29, the rising portion 31 continuous with the folding piece 30 rises. Then, the engaging projections 27 on the second side plate portion 26 side fitted in the cut grooves 28 are brought into contact with each other while leaning against each other. Therefore, it is difficult for the locking projection 27 to come out of the cut groove 28 due to the contact with the rising portion 31. Further, when the packaging pack P is fitted in the fitting hole 22, the flange Pf of the packaging pack P is caught by the set of the locking projection 27 and the rising portion 31. That is, the existence of the set of the locking protrusion 27 and the rising portion 31 suppresses the shift movement of the packaging pack P in the fitting hole 22.

Rectangular short side plates 21 are connected to the opposite short edges of the flat plate 19 via perforated cut lines 32. Each short side plate 21 is bent downward along the score line 32. The presence of the score line 32 facilitates bending and holding the short side plate 21 in a state substantially orthogonal to the flat plate 19.

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

Vent holes 17 are also provided in the four side plates 20, 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 are also provided in the second side plate portion 26. The ventilation holes 17 of the first and second side plate portions 25, 26, which are placed in a state close to two-ply, 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 accommodated in the outer box body 2, the ventilation holes 17 are located at the corresponding positions of the side plates 5, 20 (6, 21) that overlap each other. Therefore, these ventilation holes 17 allow the inside and the outside of the outer box body 2 and the inner tray body 3 to communicate with each other, and the air permeability in the hanging packaging box 1 can be improved.

A reinforcing plate 33 that supports the flat plate 19 is connected to the pair of short side plates 21 facing each other of the four side plates 20, 21 of the inner tray body 3. In this case, a fitting groove 34 is formed at the center front end side of each short side plate 21, and each longitudinal end of the reinforcing plate 33 is fitted into each fitting groove 34 from below. A 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 contacts the central frame portion 35 of the flat plate 19 from below. Even when the packaging pack P is fitted in each fitting hole 22, the reinforcing plate 33 stably supports the central frame portion 35 of the flat plate 19, so that the group of packaging packs P is stably held. The reinforcing plate 33 is also provided with two vent holes 17 so as to correspond to the vent holes 17 provided in the long 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 in the flat plate 19 at a position near each cut line 32. By inserting the left and right hands into both the 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.
