The base plate 110 has a first side 111, a second side 112, a third side 113, and a fourth side 114 connected in sequence. The two first side plates 120 are respectively connected to the first side 111 and the third side 113. One of the first side plates 120 has at least one first groove 121 on its side, and the at least one first groove 121 is adjacent to the fourth side 114. The other first side plate 120 has at least one second groove 122, and the at least one second groove 122 is adjacent to the second side 112.

[0046] Two second side plates 130 are respectively connected to the second side 112 and the fourth side 114. One of the second side plates 130 has at least one first opening 131 on its side, and the at least one first opening 131 is adjacent to the first side 111. The other second side plate 130 has at least one second opening 132 on its side, and the at least one second opening 132 is adjacent to the third side 113.

[0047] A first connecting plate 140 connects to one of the two second side plates 130 and is disposed next to at least one first opening 131. A second connecting plate 150 connects to one of the two second side plates 130 and is disposed next to at least one second opening 132.

[0048] The first combined plate 160 is connected to the first connecting plate 140 and has at least one first snap-fit ​​structure 161. The second combined plate 170 is connected to the second connecting plate 150 and has at least one second snap-fit ​​structure 171. When the base plate 110, the two first side plates 120, the two second side plates 130, the first connecting plate 140, the second connecting plate 150, the first combined plate 160, and the second combined plate 170 are folded together, at least one first snap-fit ​​structure 161 passes through at least one second opening 132 and engages with at least one second groove 122, and at least one second snap-fit ​​structure 171 passes through at least one first opening 131 and engages with at least one first groove 121, so that the first combined plate 160 and the second combined plate 170 are respectively fixed to the two second side plates 130.

[0049] In detail, the two first side plates 120 are parallel to each other, and the two second side plates 130 are also parallel to each other. In this embodiment, the base plate 110 is rectangular, and the two first side plates 120 and the two second side plates 130 are perpendicular to the base plate 110. In other embodiments, the base plate 110 may also be square, and the two first side plates 120 and the two second side plates 130 may not be perpendicular to the base plate 110; this invention is not limited to these embodiments.

[0050] Each of the two second side plates 130 also has a third groove 133 disposed on the opposite side relative to the first opening 131 and the second opening 132. Each of the two first side plates 120 also has a fixing structure 123 disposed on the opposite side relative to the first groove 121 and the second groove 122, wherein the fixing structure 123 is adapted to engage with the adjacent third groove 133.

[0051] When the two first side panels 120 and the two second side panels 130 are folded relative to the base plate 110, the two first side panels 120 and the two second side panels 130 are fixed to each other by the fixing structure 123 and the third groove 133, and the first opening 131 is aligned with the first groove 121, and the second opening 132 is aligned with the second groove 122. In addition, in this embodiment, the base plate 110, the two first side panels 120 and the two second side panels 130 constitute an accommodating space A, which can be used to place items.

[0052] Please continue to refer to this. Figure 1 and Figure 2 In this embodiment, one side of the first connecting plate 140 is connected to one of the two second side plates 130, and the other side is connected to the first combined plate 160. Additionally, one side of the second connecting plate 150 is connected to one of the two second side plates 130, and the other side is connected to the second combined plate 170. When the two first side plates 120 and the two second side plates 130 are folded relative to the base plate 110, the first connecting plate 140 bends towards one of the two first side plates 120 and covers it, and the second connecting plate 150 bends towards the other of the two first side plates 120 and covers it.

[0053] Additionally, the first combined plate 160 is bent towards one of the two second side plates 130 and covers it, allowing the first snap-fit ​​structure 161 to pass through the second opening 132 and engage with the second groove 122. Similarly, the second combined plate 170 is bent towards the other of the two second side plates 130 and covers it, allowing the second snap-fit ​​structure 171 to pass through the first opening 131 and engage with the first groove 121. In this embodiment, there are two of each of the first groove 121, the first opening 131, and the second snap-fit ​​structure 171, as well as two of each of the second groove 122, the second opening 132, and the first snap-fit ​​structure 161. In other embodiments, the number of the first groove 121, the first opening 131, and the second snap-fit ​​structure 171 may be one or more, and the number of the second groove 122, the second opening 132, and the first snap-fit ​​structure 161 may also be one or more, as long as the number of the first groove 121, the first opening 131, and the second snap-fit ​​structure 171 is the same, and the number of the second groove 122, the second opening 132, and the first snap-fit ​​structure 161 is the same, so that when the two first side plates 120 and the two second side plates 130 are folded relative to the bottom plate 110, the first opening 131 can be aligned with the first groove 121 so that the second snap-fit ​​structure 171 can pass through the first opening 131 and engage with the first groove 121, and the second opening 132 can be aligned with the second groove 122 so that the first snap-fit ​​structure 161 can pass through the second opening 132 and engage with the second groove 122. This case is not limited to this.

[0054] As described above, the first opening 131 is located on one of the two second side plates 130 and is close to the first connecting plate 140, and one side of the first combined plate 160 is connected to the first connecting plate 140, while the other side is provided with a first snap-fit ​​structure 161. Additionally, the second opening 132 is located on one of the two second side plates 130 and is close to the second connecting plate 150, and one side of the second combined plate 170 is connected to the second connecting plate 150, while the other side is provided with a second snap-fit ​​structure 171.

[0055] In detail, when the first connecting plate 140 covers one of the two first side plates 120 and the second connecting plate 150 covers the other of the two first side plates 120, the first combined plate 160 covers the second side plate 130 connecting the second connecting plate 150, and the second combined plate 170 covers the second side plate 130 connecting the first connecting plate 140, so that the first snap-fit ​​structure 161 passes through the second opening 132 and the corresponding second groove 122, and the second snap-fit ​​structure 171 passes through the first opening 131 and the corresponding first groove 121.

[0056] In this embodiment, the second side plate 130 connecting the first connecting plate 140 also has a fourth groove 134, and the second combined plate 170 also has a fifth groove 172. When the second combined plate 170 covers the second side plate 130 connecting the first connecting plate 140, the fourth groove 134 and the fifth groove 172 overlap each other.

[0057] On the other hand, when the first connecting plate 140 and the second connecting plate 150, as well as the first combined plate 160 and the second combined plate 170, respectively cover the two first side plates 120 and the two second side plates 130, the outer surfaces of the first connecting plate 140, the second connecting plate 150, the first combined plate 160, and the second combined plate 170 will face outwards from the packaging box 100. That is to say, before assembling the packaging box 100, the required pattern can be made on the outer surfaces of the first connecting plate 140, the second connecting plate 150, the first combined plate 160, and the second combined plate 170. Then, by assembling and fixing the packaging box 100, the glue application process can be omitted, and the production of the packaging box 100 can be completed.

[0058] Please refer to Figures 3A to 3E When assembling the packaging box 100, firstly, fold the two first side panels 120 and the two second side panels 130 along the two first side edges 111 and the two second side edges 112 relative to the bottom plate 110, so that the two first side panels 120 and the two second side panels 130 are perpendicular to the bottom plate 110. At this time, the third groove 133 is located next to the fixing structure 123, and the first opening 131 is aligned with the first groove 121. Then, snap the fixing structure 123 into the adjacent third groove 133, so that the two first side panels 120 and the two second side panels 130 are fixed to each other. Then, bend the first connecting plate 140 and the second connecting plate 150 relative to the second side panel 130 towards the two first side panels 120 and cover the first side panel 120, and bend the first combined plate 160 and the second combined plate 170 relative to the first connecting plate 140 and the second connecting plate 150 towards the two second side panels 130 and cover the second side panel 130. Finally, the first snap-fit ​​structure 161 passes through the second opening 132 and engages with the second groove 122, and the second snap-fit ​​structure 171 passes through the first opening 131 and engages with the first groove 121, so that the first combined plate 160 and the second combined plate 170 are respectively fixed with the two second side plates 130, thereby fixing the packaging box 100 into shape.

[0059] In summary, the packaging box in this case is fixed by two combination panels snapping together two second side panels. Furthermore, the pattern can be made on the outer surface of the two combination panels and two connecting panels, so that after the packaging box is fixed, the step of using glue or chemical materials for mounting can be omitted, reducing the number of steps in the packaging box manufacturing process and reducing environmental pollution.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this case, and not to limit them; although this case has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this case.
