Please refer to FIG. 1. FIG. 1 is a three-dimensional schematic diagram of a packaging box 100 according to an embodiment of the present invention, wherein the first opening OP1 and the second opening OP2 are not closed. In this embodiment, as shown in FIG. 1, a packaging box 100 includes a wall 110. The wall 110 is surrounded by and defines a storage space SP. The wall 110 has a first edge 111 and a second edge 112 that are opposite to each other. The first edge 111 is surrounded by and defines a first opening OP1. The second edge 112 is surrounded by and defines a second opening OP2. The storage space SP, the first opening OP1, and the second opening OP2 are connected to each other. The storage space SP is configured to accommodate an object 200 (see FIGS. 6 to 8 for the object 200). For example, the object 200 may be an electronic product, but the present invention is not limited thereto.

Furthermore, in this embodiment, the packaging box 100 further includes a plurality of first bottom covers 120 and a plurality of second bottom covers 130. Specifically, as shown in FIG. 1 , the number of the first bottom covers 120 and the number of the second bottom covers 130 are two, respectively. The first bottom covers 120 are respectively connected to the first edge 111 and are configured to be bent relative to the wall 110 to at least partially close the first opening OP1, and the second bottom covers 130 are respectively located between two adjacent ones of the first bottom covers 120 and connected to the first edge 111, and the second bottom covers 130 are respectively configured to be bent relative to the wall 110 to at least partially close the first opening OP1. In practice, the user first bends the first bottom cover 120 to at least partially close the first opening OP1, and then bends the second bottom cover 130 to at least partially close the first opening OP1 and cover the first bottom cover 120. In other words, after being bent, the second bottom cover 130 is located outside the first bottom cover 120.

Furthermore, in the present embodiment, the packaging box 100 further includes a plurality of first covers 150 and a plurality of second covers 160. Specifically, as shown in FIG. 1 , the number of the first covers 150 and the number of the second covers 160 are two, respectively. The first covers 150 are respectively connected to the second edge 112 and are configured to be bent relative to the wall 110 to at least partially close the second opening OP2, and the second covers 160 are respectively located between two adjacent ones of the first covers 150 and connected to the second edge 112, and the second covers 160 are respectively configured to be bent relative to the wall 110 to at least partially close the second opening OP2. In practice, the user first bends the first cover 150 to at least partially close the second opening OP2, and then bends the second cover 160 to at least partially close the second opening OP2 and cover the first cover 150. In other words, after being bent, the second cover 160 is located outside the first cover 150.

Please refer to FIG. 2. FIG. 2 is an enlarged front view of the first bottom cover 120 of FIG. 1. In the present embodiment, as shown in FIG. 2, at least one of the first bottom covers 120 includes a bottom cover body 121, a first bending portion 122, and a second bending portion 123. The bottom cover body 121 has a first through hole H1 and a second through hole H2. The first bending portion 122 is connected to the bottom cover body 121 and is configured to bend relative to the bottom cover body 121. The first bending portion 122 is located at the first through hole H1 before bending, as shown in FIG. 2. The second bending portion 123 is connected to the bottom cover body 121 and is configured to bend relative to the bottom cover body 121. Similarly, the second bending portion 123 is located at the second through hole H2 before bending, as shown in FIG. 2.

Please refer to Figures 3 and 4. Figure 3 is a three-dimensional schematic diagram of the packaging box 100 of Figure 1, wherein the first opening OP1 has been closed. Figure 4 is an enlarged schematic diagram of the range M of Figure 3. In this embodiment, as shown in Figures 3 and 4, the first bending portion 122 and the second bending portion 123 are both bent relative to the bottom cover body 121, and the bent first bending portion 122 and the bent second bending portion 123 are connected to each other to form a first reinforcement structure RS1. Since the first reinforcing structure RS1 is formed by bending the first bending portion 122 and the second bending portion 123 respectively relative to the bottom cover body 121 and connecting them, the first reinforcing structure RS1 is a hollow structure and has good structural strength, which makes the first reinforcing structure RS1 not easy to deform, and the bottom cover body 121 connected to the first reinforcing structure RS1 is also not easy to deform. In this way, the overall structural strength of the packaging box 100 can be improved, and the packaging box 100 can better withstand external impact, thereby effectively protecting the object 200 contained therein.

Furthermore, since the formation of the first reinforcement structure RS1 does not involve additional materials, this not only saves costs but also brings convenience to the manufacture of the packaging box 100.

More specifically, in this embodiment, as shown in FIGS. 2 and 4 , the first bending portion 122 includes a first main body 1221 and a plurality of first coupling portions 1222. The first main body 1221 has a third edge 1221a (shown by a dotted line in FIG. 2 ) and a fourth edge 1221b opposite to each other, the third edge 1221a is connected to the bottom cover main body 121, and the first coupling portion 1222 is disposed on the fourth edge 1221b. The second bending portion 123 includes a second main body 1231 and a plurality of second coupling portions 1232. The second body 1231 has a fifth edge 1231a (shown by a dotted line in FIG. 2 ) and a sixth edge 1231b opposite to each other. The fifth edge 1231a is connected to the bottom cover body 121, and the second coupling portion 1232 is disposed on the sixth edge 1231b. The second coupling portion 1232 is configured to couple with the first coupling portion 1222. By coupling the first coupling portion 1222 of the first bending portion 122 to the second coupling portion 1232 of the second bending portion 123, the first bending portion 122 and the second bending portion 123 can be fixed to each other.

In practical applications, as shown in Figures 2 and 4, the first coupling portion 1222 of the first bent portion 122 is convex, and the second coupling portion 1232 of the second bent portion 123 is perforated. By inserting the convex first coupling portion 1222 into the perforated second coupling portion 1232, the first bent portion 122 and the second bent portion 123 can be fixed to each other.

Furthermore, as shown in FIG2 , the fourth edge 1221b of the first bent portion 122 has a first length L1, and the sixth edge 1231b of the second bent portion 123 has a second length L2. According to actual conditions, for example, the first length L1 may be substantially the same as the second length L2.

In addition, according to the actual situation, as shown in Figures 2 and 4, the first bottom cover 120 defines a fourth edge 1221b' away from and opposite to the first edge 111. In this case, the first length L1' is longer than the second length L2, that is, the first length L1' is different from the second length L2.

Please refer to Figures 5 and 6. Figure 5 is a three-dimensional schematic diagram of the packaging box 100 of Figure 3, in which the first filler 140 has been placed in the accommodating space SP. Figure 6 is a three-dimensional schematic diagram of the packaging box 100 of Figure 5, in which the object 200 has been supported on the first filler 140. In the present embodiment, the packaging box 100 further includes at least one first filler 140. In practical applications, before placing the object 200 in the accommodating space SP, the user first places a certain number of first fillers 140 in the accommodating space SP. For example, as shown in Figures 5 and 6, the number of first fillers 140 is four, and they are placed in the four corners of the accommodating space SP respectively. As shown in Figure 6, the first filler 140 is configured to at least partially cover the object 200 to provide protection for the object 200. It is worth noting that, as shown in FIG. 5 , the first filler 140 abuts against the corresponding first reinforcing structure RS1. More specifically, the first filler 140 is placed between the wall 110 and the first reinforcing structure RS1. In this way, the first filler 140 can be restricted by the wall 110 and the first reinforcing structure RS1 and fixed in the accommodating space SP. Moreover, since the first filler 140 abuts against the corresponding first reinforcing structure RS1, when the packaging box 100 is hit, the first filler 140 can transmit the impact force to the adjacent first reinforcing structure RS1, thereby dispersing the impact force received by the packaging box 100, which is beneficial for the packaging box 100 to withstand the impact and provide protection for the object 200 accommodated therein. In practical applications, the first filler 140 can be expandable polystyrene (EPS), but the present invention is not limited thereto.

Please refer to Figures 7 and 8. Figure 7 is a three-dimensional schematic diagram of the packaging box 100 of Figure 6, wherein the first cover 150 has closed the second opening OP2. Figure 8 is a cross-sectional view along the line segment A-A of Figure 7. In the present embodiment, the packaging box 100 further includes at least one second filler 170. As shown in Figures 7 and 8, the second filler 170 is located in the accommodating space SP and at least partially covers the object 200. More specifically, the object 200 is at least partially covered between the first filler 140 and the second filler 170, so the object 200 can be protected by the first filler 140 and the second filler 170. In practical applications, the second filler 170 can also be EPS, but the present invention is not limited to this.

Please refer to FIG. 9. FIG. 9 is an enlarged schematic diagram showing the range N of FIG. 8. As shown in FIG. 9, the first cover 150 includes a cover body 151, a third bend portion 152, and a fourth bend portion 153. The third bend portion 152 and the fourth bend portion 153 are respectively connected to the cover body 151 and are bent relative to the cover body 151, and the bent fourth bend portion 153 and the bent third bend portion 152 are connected to each other to form a second reinforcement structure RS2. The second reinforcement structure RS2 makes the first cover 150 less likely to deform, so that the overall structural strength of the packaging box 100 can be improved, thereby effectively protecting the object 200 contained therein.

Moreover, as shown in FIG. 9 , the second filler 170 abuts against the second reinforcing structure RS2. Therefore, when the packaging box 100 is impacted, the second filler 170 can transmit the impact force to the adjacent second reinforcing structure RS2, thereby dispersing the impact force received by the packaging box 100, which is beneficial for the packaging box 100 to withstand the impact and provide protection for the object 200 contained therein.

In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages:

(1) Since the first reinforcement structure is formed by the first bending portion and the second bending portion being bent relative to the bottom cover body and connected, the first reinforcement structure is a hollow structure with good structural strength, which makes the first reinforcement structure not easy to deform, and the bottom cover body connected to the first reinforcement structure is also not easy to deform. In this way, the overall structural strength of the packaging box can be improved, and the packaging box can better withstand external impact, thereby effectively protecting the objects contained therein.

(2) Since the formation of the first reinforcement structure and the second reinforcement structure does not involve additional materials, this not only saves costs but also brings convenience to the production of the packaging box.

(3) Since the first filler abuts against the corresponding first reinforcing structure, when the packaging box is impacted, the first filler can transmit the impact force to the adjacent first reinforcing structure, thereby dispersing the impact force received by the packaging box, which is beneficial for the packaging box to withstand the impact and provide protection for the objects contained therein.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined in the attached patent application.
