FIGS. 6 and 7 show that the main cover 20 is a substantially flat board including a first board 202, a second board 203, a third board 204, and a fourth board 205. A first foldable edge 22 is formed between the first board 202 and the second board 203. A second foldable edge 23 is formed between the second board 203 and the third board 204. A third foldable edge 24 is formed between the third board 204 and the fourth board 205. The first, second, and third foldable edges 22, 23, 24 are substantially parallel to each other. The first/second, second/third, and third/fourth boards 202/203, 203/204, 204/205 are foldable along the first, second, and third foldable edges 22, 23, 24, respectively. A connecting edge 21 of the first board 202 is connected to a substantially middle portion of the top surface 12. The first board 202 is foldable relative to the bottom surface 11.
The second board 203 and the fourth board 205 correspond to the side surfaces 13. The third board 204 corresponds to the top surface 12. When packaging the box 10 with the main cover 20, the main cover 20 can be folded, such that the first board 202, the second and fourth boards 203, 205, and the third board 204 cover the bottom surface 11, the side surfaces 13, and the top surface 12, respectively (as shown in FIG. 1).
In this exemplary embodiment, a plurality of fixing members 27 is attached to the fourth board 205 and the side surface 13 defining the step 131, so that the fourth board 205 can be attached to the side surface 13 defining the step 131. The fixing members 27 can be Velcro, magnetic members, or other suitable attaching mechanism.
The main cover 20 can also be folded to support the box 10 at a suitable viewing angle, such that an angle is formed between the first board 202 and the bottom surface 11, and one of the side surfaces 13 corresponding to the second board 203 resists against the third board 204 (as shown in FIG. 7).
In this exemplary embodiment, a plurality of ribs 26 protrudes from a surface of the third board 204 facing the box 10. The viewing angle of the box 10 can be adjusted by moving the side surface 13 corresponding to the second board 203 to different ribs 26.
FIG. 3 shows that the support 30 includes a bottom wall 31, two opposite first sidewalls 32, and a second sidewall 33 connected to the first sidewall 32. The first sidewalls 32 and the second sidewall 33 surround edges of the bottom wall 31 to cooperatively define a receiving chamber 36. A side of the support 30 opposite to the second sidewall 33 defines an opening 34 communicating with the receiving chamber 36. Each first sidewall 32 and the second sidewall 33 define through slots 37. The support 30 further includes a plurality of first fixed boards 38 extending substantially perpendicularly from edges of the first sidewall 32 and the second sidewall 33 opposite to the bottom wall 31. The first fixed boards 38 extend along a direction away from the receiving chamber 36. A second fixed board 341 extends substantially perpendicularly from an edge of the bottom wall 31 at the opening 34.
In assembly, the support 30 is received in the first receiving space 122. The opening 34 is aligned with the step 131. The first fixed boards 38 are fixed to the top surface 12. The second fixed board 341 is fixed to the separating board 135. A sound chamber 40 is cooperatively defined between the bottom wall 31 and the box 10. The through slots 37 communicate with the sound chamber 40. In other embodiments, the support 30 can be omitted, such that the receiving chamber 36 can be directly defined in the box 10.
To package the electronic device 200 in the packaging box 100, the electronic device 200 is received in the receiving chamber 36 in a first orientation (i.e. a landscape orientation as shown in FIG. 8). The main cover 20 is folded to cover the box 10. The first board 202, the second and fourth boards 203, 205, and the third board 204 are attached to the bottom surface 11, the side surfaces 13, and the top surface 12, respectively. The fourth board 205 is fixed to the side surface 13 defining the step 132 so that the electronic device 100 is packaged in the box 10. Furthermore, the second receiving space 136 and the sound chamber 40 can be used to receive the accessories. The side cover 14 can be folded to open or close the second receiving space 136 and the sound chamber 40.
FIGS. 8 and 9 show the packaging box 100 with the electronic device 200. The main cover 20 is opened and folded to expose the electronic device 200. An angle is formed between the first board 202 and the bottom surface 11. The side surface 13 corresponding to the second board 203 resists against the third board 204. Thus, the box 10 is in an inclined state, and the electronic device 200 received in the receiving chamber 36 can be viewed at a suitable viewing angle. The viewing angle (i.e. an inclined angle of the box 10) of the electronic device 200 can be adjusted by moving the side surface 13 corresponding to the second board 203 to different ribs 26.
Furthermore, speakers of the electronic device 200 can be aligned with the through slots 37 of the first sidewalls 32. Sound can be input to the sound chamber 40 from the through slots 37, and output from the sound holes 142. Therefore, the support 30 will not negatively influence the sound from the electronic device 200.
In addition, the electronic device 200 can be received in the receiving chamber 36 in a second orientation (i.e. a portrait orientation as shown in FIG. 9) and partially received in the step 131. When the electronic device 200 is out of power, the data cable can be conveniently connected to the electronic device 200 through the through hole 141 to charge the electronic device 200 without removing the electronic device 200 from the receiving chamber 36.
In summary, the packaging box 100 can be reused by the user. Thus, the packaging box 100 is eco-friendly. In addition, the packaging box 100 has a relatively simple structure and is easy to use.
It is believed that the exemplary embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
