[0047] Example

[0048] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment provides a paper box, including a box body 1 and an outer connecting plate 2.

[0049] The box body 1 includes an inner bottom plate 10, a first side plate 11 folded on one side of the inner bottom plate 10, and a second side plate 12 folded on the other side of the inner bottom plate 10, and the first side plate 11 and the second side plate 12 are arranged opposite to each other. A first splicing panel 131 is folded over on one end of the first side panel 11, and a second splicing panel 141 is folded over on the other end of the first side panel 11; a third splicing panel 132 is folded over on one end of the second side panel 12, which is connected to or split from the first splicing panel 131, and the first splicing panel 131 and the third splicing panel 132 are connected to form a third side panel 13; a fourth splicing panel 142 is folded over on the other end of the second side panel 12, which is connected to or split from the second splicing panel 141, and the second splicing panel 141 and the fourth splicing panel 142 are connected to form a fourth side panel 14; the first side panel 11, the third side panel 13, the second side panel 12 and the fourth side panel 14 are folded over on the inner bottom panel 10 to surround and form a accommodating groove for storing items.

[0050] After the third side panel 13 is separated (i.e., the connection between the first splicing panel 131 and the third splicing panel 132 is separated), and the fourth side panel 14 is separated (i.e., the connection between the second splicing panel 141 and the fourth splicing panel 142 is separated), the box body 1 can be unfolded into a flat state (e.g., Figure 1 As shown), the volume of the box body 1 can be reduced, and the box body 1 in the flat state can also be folded and collapsed along the folding line to further reduce the area of the box body 1. In this way, the box body 1 can be quickly folded and collapsed, reducing the space occupied by the box body 1 for the purpose of storage and transportation.

[0051] The outer connecting plate 2 includes an outer bottom plate 21, a first outer side plate 22, a top plate 23, and a second outer side plate 24 that are folded and connected in sequence. The inner bottom plate 10 of the box body 1 can be connected to the outer bottom plate 21 by gluing, that is, the box body 1 is fixedly arranged on the top surface of the outer bottom plate 21 of the outer connecting plate 2. Among them, the top plate 23 is a cover plate for covering or opening the receiving groove. By folding the outer connecting plate 2 along the folding line, the first outer side plate 22 can be fitted with the third side plate 13 of the box body 1, the second outer side plate 24 can be fitted with the fourth side plate 14 of the box body 1, and the top plate 23 can cover the notch of the receiving groove of the box body 1 (such as Figure 5 As shown), in order to store items in the accommodating groove; unfolding the outer connecting plate 2 can open the notch of the accommodating groove of the box body 1 (as shown Figure 4 The outer connecting plate 2 wraps around the box body 1, further strengthening the box body 1 and preventing damage during use or transport. When the box body 1 is unfolded into a flat position, the outer connecting plate 2 folds along the folding line and folds together with the box body 1 for easy storage and transportation.

[0052] This makes the paper box easy to assemble and disassemble. By folding and splicing, the box can be quickly formed to facilitate storage. Once folded and folded, the box significantly reduces the space it takes up, making it easier to store and transport. Furthermore, since the box is formed by folding and splicing, it doesn't require gluing or nailing, making it less susceptible to damage or marks when disassembled. It can also be folded and re-formed for reuse, effectively increasing the box's reuse rate and contributing to environmental protection.

[0053] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, a first covering paperboard 101 is provided on the side of the inner bottom plate 10 adjacent to the first side plate 11 , and a second covering paperboard 102 is provided on the other side of the inner bottom plate 10 adjacent to the first side plate 11 .

[0054] Specifically, the first wrapping cardboard 101 includes a first edge 1011 wrapped around the outside of the fourth side panel 14 and a second edge 1012 folded over the top edge of the first edge 1011 and wrapped around the inside of the fourth side panel 14. Since the fourth side panel 14 is formed by splicing the second splicing panel 141 and the fourth splicing panel 142, the first wrapping cardboard 101 is folded to wrap around the fourth side panel 14, thereby strengthening the connection strength between the second splicing panel 141 and the fourth splicing panel 142.

[0055] Furthermore, the second wrapping paperboard 102 includes a third edge 1021 that wraps around the outside of the third side panel 13, and a fourth edge 1022 that is folded over the top edge of the third edge 1021 and wraps around the inside of the third side panel 13. By folding the second wrapping paperboard 102 over the third side panel 13, the connection strength between the first splicing panel 131 and the third splicing panel 132 is strengthened, thereby further strengthening the strength of the third side panel 13. In this way, the strength of the spliced third and fourth side panels 13, 14, is strengthened by the first wrapping paperboard 101 and the second wrapping paperboard 102, thereby improving the overall stability of the box body 1 after folding.

[0056] like Figure 3As shown, in this embodiment, one end of the first side panel 11 is folded up to provide a first edge 111 attached to the outside of the first splicing panel 131, and the other end of the first side panel 11 is folded up to provide a second edge 112 attached to the outside of the second splicing panel 141; one end of the second side panel 12 is folded up to provide a third edge 121 attached to the outside of the third splicing panel 132, and the other end of the second splicing panel 141 is folded up to provide a fourth edge 122 attached to the outside of the fourth splicing panel 142. After the box body 1 is folded and spliced so that the first side panel 11, the third side panel 13, the second side panel 12 and the fourth side panel 14 are folded and surrounded on the inner bottom panel 10 to form a receiving groove for storing items, the first edge 111, the second edge 112, the third edge 121 and the fourth edge 122 are folded and attached to the four corners of the box body 1 to strengthen the protection of the edges and corners of the box body 1, prevent the box body 1 from being damaged by bumps, and extend the service life.

[0057] like Figure 1 and Figure 3 As shown, in this embodiment, a reinforcing plate 10111 is provided on the inner side surface of the first edge 1011, a handle 10112 is provided on the outer side surface of the first edge 1011, and a handle hole 241 for avoiding the handle 10112 is provided on the second outer plate 24.

[0058] Specifically, the reinforcing plate 10111 is used to strengthen the structural strength of the first edge 1011, thereby strengthening the structural strength of the fourth side panel 14, so as to ensure the stability of the receiving groove surrounded by the first side panel 11, the third side panel 13, the second side panel 12 and the fourth side panel 14. The outer connecting plate 2 can cover the notch of the receiving groove of the box body 1 after being folded along the folding line. At this time, the second outer panel 24 of the outer connecting plate 2 fits with the outer side surface of the first edge 1011 covering the fourth side panel 14 of the box body 1. The handle 10112 provided on the outer side surface of the first edge 1011 extends through the handle hole 241 on the second outer panel 24, making it convenient for the user to hold the handle 10112 to carry the paper box. The handle 10112 and the handle hole 241 that are nested with each other can also limit the deviation of the second outer panel 24, thereby improving the stability of the paper box.

[0059] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, a first magnetic component 10113 is provided on the first edge 1011 , and a second magnetic component 242 adsorbed to the first magnetic component 10113 is provided on the second outer plate 24 .

[0060] Specifically, the first magnetic member 10113 can be set in the first edge 1011 or on the outer side of the first edge 1011, and the second magnetic member 242 can be set in the second outer panel 24 or on the inner side of the second outer panel 24. When the outer connecting plate 2 is folded so that the top plate 23 covers the notch of the receiving groove of the box body 1, the second outer panel 24 fits with the first edge 1011. Under the action of the adsorption between the first magnetic member 10113 and the second magnetic member 242, the outer connecting plate 2 can be fixed in the state of being covered outside the box body 1 after being folded, so that the top plate 23 can firmly cover the notch of the receiving groove, thereby enhancing the overall stability of the paper box after being formed.

[0061] like Figure 1 As shown, in this embodiment, a slot 1321 is provided at the end of the third splicing plate 132, and the width of the slot 1321 gradually increases from the outside to the inside. A protrusion 1311 is provided at the end of the first splicing plate 131, which engages with or disengages from the slot 1321. Furthermore, the second splicing plate 141 has the same structural arrangement as the first splicing plate 131, and the fourth splicing plate 142 has the same structural arrangement as the third splicing plate 132. The slot 1321 may be a trapezoidal slot, and the protrusion 1311 may be a trapezoidal protrusion that engages with the trapezoidal slot. The trapezoidal shape can improve stability during connection, thereby ensuring the stability of the third side panel 13 and the fourth side panel 14.

[0062] like Figure 3 and Figure 4 As shown, this embodiment further includes a bottom baffle 3, which is embedded in the inner bottom plate 10 within the accommodating groove. The bottom baffle 3 strengthens the bottom of the box body 1, and the side walls of the bottom baffle 3 can abut against the second edge 1012 of the first wrapping paperboard 101 and the fourth edge 1022 of the second wrapping paperboard 102, thereby reinforcing the stability of the first wrapping paperboard 101 wrapped around the fourth side plate 14 and the stability of the second wrapping paperboard 102 wrapped around the third side plate 13, thereby improving the structural strength of the third side plate 13 and the fourth side plate 14.

[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
