 Hereinafter, details of the embodiment of the present invention will be described with reference to FIGS. In FIG. 1, as a packaging box for packaging the electric device X, a cardboard carton box 1 having a volume sufficiently larger than that of the flat rectangular electric device X is used. That is, the carton box 1 is provided with four opening flaps 1a on its side wall 1b that can be folded after housing the electric device X, and the upper opening can be closed by folding these opening flaps 1a.

A pair of corrugated cardboard cushions 2L and 2R, which are bent from corrugated cardboard prior to housing the electric device X, are arranged at both inner ends of the carton box 1. Both corrugated cardboard cushions 2L and 2R, which will be described in detail later with reference to FIG. 5, are processed to have a U-shaped cross section including a side wall 2a, a bottom wall 2b, and a top wall 2c which are bent at a right angle, as shown in FIG. However, since the stopper pieces 2d that can elastically contact the inner surface of the side wall 1b of the carton box 1 are provided at the front and rear ends thereof, when these step ball cushions 2L and 2R are inserted into the carton box 1, the stopper pieces are inserted. The corrugated cardboard cushions 2L and 2R do not move due to the contact of 2d. Further, a device receiving chamber 3 into which the end of the electric device X can be inserted is formed on the facing surfaces of the corrugated cardboard cushions 2L and 2R. These device receiving chambers 3 are open at the upper side to receive the ends of the electric devices X from above, and the bottom surface of the end of the electric devices X received in the device receiving chamber 3 is horizontal from the side wall 2a. It is received by the bent device receiving piece 2e. A buffer piece 2f bent downward from the top wall 2c is elastically contacted with the end surface of the electric device X in the housed state, and a lower end portion 2g of the buffer piece 2f extends from the end portion of the top wall 2c. It is bent downward and the tip ear 2h is locked to the surface of the reinforcing piece 2i inserted into the slot 4 on the surface of the device receiving piece 2e.

On the upper surface of the electric device X housed in the carton box 1, a shallow dish-shaped upper surface spacer 5 made of rigid paper such as a corrugated board is placed. Since the upper surface spacer 5 is formed to have an outer dimension that matches the inner dimension of the carton box 1, when the upper surface spacer 5 is placed on the upper surface of the electric device X, the lower surfaces of both end portions of the upper surface spacer 5 are the corrugated cardboard cushion 2L, Since the upper surface of the carton box 1 is in contact with the upper surface of the 2R, the electric equipment X can be buffered against the shock from above the carton box 1. Further, since the accessories of the electric device X such as the adapter x ₁ and the cord x ₂ can be stored inside the upper surface spacer 5, the structure is convenient for the user who opens the packaging box and the manufacturer who stores the accessories. Become. In the illustrated embodiment, a corrugated board protection plate 6 is placed on the upper surface of the upper surface spacer 5 to prevent dust and the like from entering the inside and to prevent the package from being scratched by a cutter when opening the corrugated board box. To be

FIG. 5 shows a blank of the corrugated cardboard cushions 2L and 2R described above. A reinforcing piece 2i having the above-mentioned tip ear 2h is provided above the strip-shaped ceiling wall 2c with the perforation a as a boundary. A side wall 2a and a bottom wall 2b having the perforations b and c as common sides are vertically continuous with the wall 2c. Then, the buffer piece 2f and the device receiving piece 2e that are cut by the H-shaped opening 6 are formed at the boundary between the top wall 2c and the side wall 2a, and these buffer piece 2f and the device receiving piece 2e are It is bent in the direction of the back surface in FIG. 5 from the fold lines d 1 and e 2 connecting the side portions of the H-shaped cutout 6. The slot 4 is opened on the surface of the device receiving piece 2e, and the tip ear 2h of the reinforcing piece 2i can be inserted into the slot 4. The blank is formed with a pair of folding pieces 2j and a stopper piece 2d that can be folded up at right angles from the left and right folding lines f and g of the top wall 2c and the side wall 2a toward the back surface.

Since the packaging box for the electric device X of the illustrated embodiment has the above-described structure, the corrugated cardboard cushions 2L and 2R are assembled from the blank before the packaging of the electric device X. That is, the buffer piece 2f and the device receiving piece 2e are folded from the fold lines d and e in the back surface direction of FIG. 5, and the bottom wall 2b, the top wall 2c, and the reinforcing piece 2i are perpendicular to the side wall 2a in the back surface direction of FIG. Fold it in and insert the tip ear 2h of the reinforcing piece 2i into the slot 4 to obtain an assembled state having a "U" -shaped cross section shown in FIG. Then, the folding pieces 2j and the stopper pieces 2d are folded substantially at right angles from the folding lines f and g, whereby the left and right corrugated cardboard cushions 2L and 2R are completed.

Accordingly, when the stopper pieces 2d of the completed corrugated cardboard cushions 2L and 2R are pushed inward and inserted into the carton box 1, the corrugated cardboard cushions 2L and 2R are restored by the restoring force of the stopper pieces 2d. It will be locked inside 1. For this reason, both ends of the electric device X are dropped from above the carton box 1 into the device receiving chambers 3 of the corrugated cardboard cushions 2L and 2R, and the upper surface spacer 5 and the corrugated board protection plate are placed from above the electric device X to place the carton box. The packaging work can be completed by closing the opening flap 1a.

As shown in FIG. 2, in the packed electric device X, the cushioning pieces 2f of the corrugated cardboard cushions 2L and 2R are elastically contacted with the end faces of the electric device X, and the electric device X itself is a stepped ball cushion 2L, Since it is held by the side wall 2a of 2R, it is sufficiently protected from the impact force in the horizontal direction. Further, against the impact force in the vertical direction, the electric device X is in a state of being sandwiched by the device receiving pieces 2e of the corrugated cardboard cushions 2L and 2R and the upper surface spacer 5, so that it is in a sufficient protection state. Of course, since the accessories of the electric device X can be stored in the upper surface spacer 5, the packaging work is easy and the structure is easy for the user to open.

Since the packaging box of the illustrated embodiment can be manufactured from corrugated cardboard that can be burned all, not only can it be burned easily, but the carton box 1, the corrugated cardboard cushions 2L and 2R, and the top spacer 5 must be folded small. Since the volume can be reduced, the volume becomes smaller and the waste treatment becomes easier.
