a, 9b and 10a, 10b are extended. The front and rear flange portions 7 and 8 are raised with respect to the bottom surface portion 3 and the connecting piece portions 9 of the both side flange portions 9 and 10 are formed.
a, 9b and 10a, 10b are respectively bent inward at right angles to the front and rear flange portions 7 and 8, and the opposing connecting pieces 9a and 10a and 9b and 10b are connected to their connecting ends 9a ₁ respectively. 10a ₁ and 9b ₁ and 1
By interlocking the 0b _1, square frame-like flange 11 on the periphery of the bottom portion 4 forming both sides flanges 9 and 10 are formed. Also, the flap parts 4, 5
Is formed with a joint hole 12.

On the other hand, the individually packaged carton 3 is formed in a bottomless box shape fitted on the outer peripheral side of the frame-shaped flange 11 with respect to the corrugated cardboard tray 2, and has lids 13a, 13b,
13c and 13d are formed. In addition, joint holes 14 are formed in the lower part of both sides of the individually packaged carton 3 in correspondence with the joint holes 12 on the flap portions 5 and 6 of the cardboard tray 2.

In order to store the product A in the conventional packaging outer box 1 constructed as described above, first, the cushioning material 15 is provided on the square portion of the square frame-like flange 11 on the bottom surface 4 of the cardboard tray 2. , 16, 17, and 18 are fitted. Then, the individual carton 3 is placed on the corrugated cardboard tray 2 side from the bottomless lower surface side, and the lower end portion is fitted and placed on the outer peripheral side of the rectangular frame-shaped flange 11. The joint holes 12 and 14 are overlapped with each other by contacting the lower sides of both side surfaces of the individually packaged carton 3, and the joint 19 is fitted and fixed in the joint holes 12 and 14 communicating with each other, and the cardboard tray 2 and the individually packaged carton 3 to form an outer packaging box 1.

[0007] From the opening on the upper surface side of the outer packaging box 1, that is, the opening in which the lid portions 13a to 13d on the upper surface side of the individual carton 3 are opened, for example, with a bag cover (not shown). The covered product A is stored using a lifting device or the like, and is fitted and mounted on the bottom portion 4 of the cardboard tray 2 via cushioning materials 15 to 18. In this state, after a predetermined cushioning material (not shown) is inserted from the upper opening of the individual carton 3 corresponding to each corner on the upper surface side of the product A, the lids 13a to 13d are folded and the upper opening is closed. Then, as shown in FIG.

[0009]

In the conventional packaging outer box constructed as described above, a frame-like flange formed on the peripheral edge of the bottom portion of the cardboard tray is fitted on the outer peripheral side of the upper flange of the frame. Is formed in the shape of a rectangular box having the same shape as the bottomless lower part of the individual packaging carton, so that if the product to be packaged is not a rectangular parallelepiped such as a television receiver, the frame-shaped flange and individual packaging are required. Large gaps are generated between products at each corner of the carton, and to fill these gaps, it is necessary to form a large cushioning material. Consumption will result in higher wrists and global environmental problems.

In addition, a cardboard tray 2 and individual carton 3
In the fitting connection, there is a possibility that the lower edge of the individually packaged carton easily collides with the cushioning material fitted to the cardboard tray, and there is a possibility that the fitting cannot be performed smoothly.

Further, since the frame-shaped flange of the cardboard tray and the lower peripheral surface of the individually packaged carton are close to each other over the entire circumference, a load is directly applied to the cushioning material in an inadvertent drop, and the cushioning material is separated. The product may be damaged.

Further, since the connecting pieces forming the side flanges connecting the front and rear flanges of the frame-shaped flange of the cardboard tray engage with each other, they are longer than half the length of the both side flanges. There is a problem that the peripheral length of the corrugated cardboard tray itself becomes long and a large amount of forming material is required, which increases the weight and the cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a packaging outer box capable of reducing the weight of the cushioning material and making the tray itself smaller by improving the tray. Aim.

[0014]

And a packaging outer box having a bottomless box-shaped outer body fitted and connected to the tray,
A chamfered surface is formed at both corners sandwiching at least one side of the flange of the tray.

[0015] The packaging outer box according to the present invention thus constituted has a chamfered surface formed at the corner of the flange of the tray to reduce the size and weight of the cushioning material interposed in the gap with the stored product. In addition, the length of the flange of the tray can be shortened by forming the chamfered surface of the corner, compared to the case where the corner is formed at a right angle, and the peripheral length of the tray itself which is shortened is reduced. As a result, the size and weight can be reduced. In addition, since the flange and the cushioning material are not present at the corners of the exterior body due to the chamfered surface of the corners of the flanges of the tray, the exterior body can be easily fitted to the tray.

Further, since the chamfered surface is formed only at the corners of the flanges of the tray, the exterior body can be formed in the same manner as a conventional carton and has good productivity, and the exterior shape retains a rectangular parallelepiped shape. Therefore, it is easy to handle logistics cargo.

[0017] Since there is a space at the corner of the exterior body due to the chamfered surface of the corner of the flange of the tray, a load is not directly applied to the buffer when an accidental drop or the like occurs, and the buffer is separated by dropping. Is less likely to occur and the packaged product is protected.
