 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 side cushions 2L and 2R, which are bent from cardboard prior to housing the electric device X, are arranged at both inner ends of the carton box 1. Both side cushions 2L and 2R, which will be described later in detail with reference to FIG. 5, are processed into a “U” -shaped cross section including a side wall 2a, a bottom wall 2b and a top wall 2c which are bent at right angles 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 side cushions 2L and 2R are inserted into the carton box 1, the stopper pieces 2d The side cushions 2L and 2R do not move due to the contact. Further, a device receiving chamber 3 into which the end of the electric device X can be inserted is formed on the facing surface of each of the side cushions 2L and 2R. These device receiving chambers 3 are open at the top to receive the ends of the electric device X from above, and the bottom surface of the end of the electric device 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 the lower end portion 2g of the buffer piece 2f is the end portion of the top wall 2c. 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 side spacer 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 an impact from above the carton box 1. Further, since the accessories of the electric device X such as the adapter x1 and the cord x2 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. . 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 prevent the package from being scratched by a cutter when opening the corrugated board box. To be

FIG. 5 shows a blank of the above-mentioned side cushions 2L, 2R. A reinforcing piece 2i having the above-mentioned tip ear 2h is provided above the strip-shaped top wall 2c with the perforation a as a boundary. A side wall 2a and a bottom wall 2b whose perforations b and c are common sides are vertically continuous with the top wall 2c. Then, the buffer piece 2f and the device receiving piece 2e which 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 and e that connect the side portions of the mold opening 6. Further, 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 side cushions 2L and 2R are assembled from the blank before the packaging of the electric device X. That is, the cushioning piece 2f and the device receiving piece 2e are folded from the folding lines d and e in the rear 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 rear 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. The left and right side cushions 2L and 2R are completed by folding the folding piece 2j and the stopper piece 2d at substantially right angles from the folding lines f and g.

Therefore, when the stopper pieces 2d of the completed side cushions 2L and 2R are pushed inward and inserted into the carton box 1, the side cushions 2L and 2R are inserted into the carton box 1 by the restoring force of the stopper pieces 2d. It will be locked inside the box 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 side cushions 2L and 2R, and the top spacer 5 and the corrugated board protection plate are placed from above the electric device X to place the carton. The packaging work can be completed by closing the opening flap 1a of the box 1.

As shown in FIG. 2, in the packed electric device X, the cushioning pieces 2f of the side cushions 2L and 2R are elastically brought into contact with the end surfaces of the electric device X, and the electric device X itself has side cushions 2L and 2R. Since it is held by the side wall 2a, it is sufficiently protected from the impact force in the horizontal direction. Further, with respect to 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 side cushions 2L and 2R and the upper surface spacer 5, so that the electric device X is sufficiently protected. 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.

The packaging box of the illustrated embodiment can be incinerated easily because it can be made entirely of corrugated cardboard, etc., and the carton box 1, side cushions 2L and 2R, and the upper spacer 5 can be folded small. As a result, the volume can be reduced and dust can be easily disposed.
