[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Please see Figures 1 to 11To address the problem of large packaging box volume hindering the storage and transportation of empty boxes, this utility model provides a convenient transportable quadrangular prism-shaped packaging profile 100. The packaging profile 100 includes two side plate profiles 10 and at least one cover plate profile 20. Each side plate profile 10 includes an integrally formed first side plate 11 and a second side plate 12, with the first side plate 11 and the second side plate 12 forming an included angle of 45° to 90° at their adjacent two sides. A first engaging structure 112 is provided on the first free side 111 of the first side plate 11, and a locking structure 112 is provided on the second free side 121 of the second side plate 12. A second engaging structure 122 is engaged with the first engaging structure 112; two side panel profiles 10 are spliced ​​together opposite each other, and the two side panel profiles 10 are spliced ​​together to form a quadrangular prism-shaped packaging box side panel 300 by engaging the first engaging structure 112 with the second engaging structure 122 on the other side panel profile 10; a third engaging structure 21 is provided on the cover profile 20, and a fourth engaging structure 13 is provided on the top or bottom of the side panel profile 10 to engage with the third engaging structure 21, so as to realize that the cover profile 20 is engaged with the top or bottom of the packaging box side panel 300 formed by splicing the two side panel profiles 10.

[0025] It is understood that the term "integrated molding" in this embodiment can refer to a plastic structure integrally molded by injection molding; a material integrally molded by casting; or a structure integrally molded after curing a foamed material.

[0026] Preferably, in this embodiment, the structure can be integrally formed by thermoforming and foaming with organic fibers and starch-based adhesives, supplemented with inorganic fillers, release agents and other materials.

[0027] This invention employs an integrally molded side panel profile 10 and cover panel profile 20, with interlocking structures on the free sides of the side panel profile 10. This allows the two side panel profiles 10 to be quickly assembled to form a quadrangular prism-shaped packaging box side panel 300. The cover panel profile 20 is then fixed to the top or bottom of the side panel via the interlocking structure. This design allows the packaging box 200 to be disassembled into 3-4 components when not in use, such as two side panel profiles 10 plus one or two cover panel profiles 20. The side panel profiles 10 can be stacked for storage, significantly reducing the space occupied by the empty box and facilitating warehousing and transportation. Simultaneously, the interlocking structure facilitates assembly without additional tools, improving the assembly efficiency and reusability of the packaging box 200, and effectively reducing packaging costs.

[0028] It should be noted that, Figure 3 The red auxiliary line (which only serves as an indicator in the diagram) marks the first free side. Figure 4 The yellow auxiliary line (which only serves as an indicator in the diagram) marks the second free side.

[0029] In one embodiment, see Figures 1 to 2 The packaging profile 100 provided by this utility model includes two side panel profiles 10 and at least one cover plate profile 20. Each side panel profile 10 is integrally formed and includes a first side panel 11 and a second side panel 12. The first side panel 11 and the second side panel 12 are connected at adjacent sides by a fixing edge 14 to form an included angle of 45° to 90° (e.g., 90°, see [reference]). Figure 3 ).

[0030] In other implementations, the included angle can be set according to the needs of shipment. Considering that if the included angle is too small, the packaging box will be closer to flat, so 45°-90° is generally preferred.

[0031] In one embodiment, see Figure 4 , Figure 6 and Figure 9 The first side plate 11 has a first engaging structure 112 on its first free side 111, and the second side plate 12 has a second engaging structure 122 on its second free side 121 that engages with the first engaging structure 112. The first engaging structure 112 includes an upper hook portion 1121 on the upper half of the first free side 111 of the first side plate 11 and a lower edge portion 1122 on the lower half of the first free side 111 of the first side plate 11. The second engaging structure 122 includes an upper edge portion 1221 on the upper half of the second free side 121 of the second side plate 12 and a lower hook portion 1222 on the lower half of the second free side 121 of the second side plate 12.

[0032] There are two side panel profiles 10. The two side panel profiles 10 are spliced ​​together opposite each other. The upper edge 1221 of one side panel profile 10 can be engaged with the upper hook 1121 of the other side panel profile 10. At the same time, the upper hook 1121 of the side panel profile 10 is engaged with the lower edge 1122 of the other side panel profile 10. Thus, the two side panel profiles 10 are spliced ​​together to form a quadrangular prism-shaped packaging box side panel 300. The upper and lower engagement forms an interlocking structure, thereby ensuring that the packaging side panel 200 is firmly connected to form a complete packaging box 200.

[0033] In one embodiment, see Figure 3 and Figure 4 The adjacent sides of the first side plate 11 and the second side plate 12, which are integrally formed, are fixed edges 14. The first side plate 11 extends in the first direction of the fixed edge 14, and the second side plate 12 extends in the second direction of the fixed edge 14.

[0034] Furthermore, the lower edge portion 1122 is provided on the lower half of the first free side 111, and the lower edge portion 1122 is a lower edge that protrudes from the first free side 111 along a first direction; the upper hook portion 1121 is provided on the upper half of the first free side 111, and the upper hook portion 1121 includes a first extension portion 11211 that protrudes from the first free side 111 along a first direction and is coplanar with the first side plate 11, and a second extension portion 11212 that extends from the end of the first extension portion 11211 along a second direction, so as to form an upper hook with an L-shaped structure, so as to engage with the lower edge.

[0035] Furthermore, the upper edge portion 1221 is provided on the upper half of the second free side 121, and the upper edge portion 1221 is an upper edge that protrudes from the second free side 121 along the second direction; the lower hook portion 1222 is provided on the lower half of the second free side 121, and the lower hook portion 1222 includes a third extension portion (not shown in the figure) that protrudes from the second free side 121 along the second direction and is coplanar with the second side plate 12, and a fourth extension portion (not shown in the figure) that extends from the end of the third extension portion along the first direction, so as to form an L-shaped lower hook to facilitate engagement with the upper edge.

[0036] In one embodiment, the outer surface of the lower edge is lower than the outer surface of the first side plate 11, and a first step (not shown) is formed between the lower edge and the outer surface of the first side plate 11. The thickness of the first step in the direction perpendicular to the plane of the first side plate 11 is the same as the thickness of the fourth extension in the second direction. The sum of the width of the first step in the direction along the plane of the first side plate 11 and the thickness of the first side plate 12 is the same as the length of the fourth extension in the first direction, so as to ensure that the surface is flat and the structure is tight when engaged, thereby ensuring that the inner and outer surfaces are aligned when engaged and avoiding gaps.

[0037] Furthermore, the inner surface of the lower edge is flush with the inner surface of the first side plate 11, and the extension length of the first extension 11211 along the first direction is consistent with the thickness of the lower edge in the direction perpendicular to the plane of the first side plate 11, so as to ensure a tight fit when engaged, thereby ensuring that the inner and outer surfaces are aligned when engaged and avoiding gaps.

[0038] Furthermore, the outer surface of the upper retaining edge is lower than the outer surface of the second side plate 12, and a second step (not shown in the figure) is formed between the upper retaining edge and the outer surface of the second side plate 12. The thickness of the second step in the direction perpendicular to the plane of the second side plate 12 is the same as the thickness of the second extension 11212 in the second direction. The sum of the width of the second step in the direction along the plane of the second side plate 12 and the thickness of the second side plate 12 is the same as the length of the second extension 11212 in the second direction, so as to ensure that the surface is flat and the structure is tight when engaged, thereby ensuring that the inner and outer surfaces are aligned when engaged and avoiding gaps.

[0039] Furthermore, the inner surface of the upper edge is flush with the inner surface of the second side plate 12, and the extension length of the third extension in the first direction is consistent with the thickness of the upper edge in the direction perpendicular to the plane of the second side plate 12, so as to ensure a tight fit when engaged, thereby ensuring that the inner and outer surfaces are aligned when engaged and avoiding gaps.

[0040] Since both the lower locking edge 1122 and the upper locking hook 1121 protrude from the first free side 111, and both the upper locking edge 1221 and the lower locking hook 1222 protrude from the second free side 121; the lower locking hook 1222 on the first free side 111 and the upper locking hook 1121 abut against each other in the lateral direction, the lower locking hook 1222 prevents the first side plate 11 from sliding downward, and the upper locking hook 1121 prevents the second side plate 12 from sliding upward.

[0041] At the same time, please combine Figure 1 Through the dimensional design of each component of the first interlocking structure 112 and the second interlocking structure 122, the outer surface of the assembled straight quadrangular prism environmentally friendly packaging box 200 is a smooth plane without steps, with a simple appearance and less prone to bumps and knocks.

[0042] Further, please refer to Figure 3 and Figure 6 The lower locking edge 1122 and the upper locking hook 1121 each occupy half the length along the extension direction of the first free side 111. That is, the upper half of the first free side 111 is the upper locking hook 1121, and the lower half of the first free side 111 is the lower locking edge 1122, so that the overall locking structure is evenly distributed and the splicing stability is improved.

[0043] In one embodiment, see Figure 7 and Figure 2 The cover profile 20 provided by this utility model includes a top cover 22. Each of the four sides of the top cover 22 is provided with a third engaging structure 21, which engages with the fourth engaging structure 13 on the top of the first side plate 11 and the second side plate 12 respectively. The third engaging structure 21 is engaged in the fourth engaging structure 13, so that the top cover 22 is firmly covered on the top of the side panel 300 of the packaging box.

[0044] In one embodiment, the cover profile 20 provided by this utility model also includes a bottom cover (not shown in the figure). The third engaging structure 21 on the four sides of the bottom cover engages with the fourth engaging structure 13 at the bottom of the first side plate 11 and the second side plate 12 to form a bottom closed structure of the packaging box 200.

[0045] In one embodiment, see Figure 3 and Figure 5The side plate profile 10 provided by this utility model also includes a triangular base plate 15 integrally formed with the first side plate 11 and the second side plate 12. The two right-angled sides of the triangular base plate 15 are respectively fixed to the bottom edges of the first side plate 11 and the second side plate 12 to enhance the bottom support.

[0046] Please refer to Figure 3 and Figure 8 The included angle between the first side panel 11 and the second side panel 12 is 90°. After the two side panel profiles 10 are spliced ​​together, they form a straight quadrangular prism side panel 300 of the packaging box. The structure is stable and suitable for standard packaging.

[0047] Further, please refer to Figure 3 and Figure 4 The inner wall of the first side plate 11 is provided with a number of first reinforcing ribs 113 at equal intervals, and the inner wall of the second side plate 12 is provided with second reinforcing ribs 123 at equal intervals, so as to improve the compressive strength and durability of the side plate.

[0048] In one embodiment, see Figure 11 The edge of the triangular base plate 15 adjacent to the outer surface of the first side plate 11 is called the rib edge 151, and the edge adjacent to the outer surface of the second side plate 12 is called the hook edge 152. A triangular notch 154 is formed at the intersection of the rib edge 151 and the hypotenuse 153 of the base plate 15. The hypotenuse of the notch 154 coincides with the hypotenuse 153 of the base plate 15, and the vertex of the notch 154 coincides with the endpoint of the rib edge 151. The height of the notch 154 is greater than the thickness of the first side plate 11. The long side of 54 coincides with the side edge 151; at the junction of the hook edge 152 and the hypotenuse 153 of the base plate 15, a triangular protrusion 155 is formed on the same plane as the base plate 15. The hypotenuse of the protrusion 155 coincides with the hypotenuse 153 of the base plate 15, and the vertex of the protrusion 155 is consistent with the endpoint of the hook edge 152. The height of the protrusion 155 is greater than the height of the second side plate 12. The long side of the protrusion 155 coincides with the side edge 151, which effectively enhances the stability of the splicing of the base plate 15.

[0049] Furthermore, there is an upper inclined locking edge 156 extending from the inclined side 153 of the base plate 15 near the notch 154, and a lower inclined locking edge 157 extending from the inclined side 153 of the base plate 15 near the locking protrusion 155 and splicing with the upper inclined locking edge 156.

[0050] Specifically, the upper inclined edge 156 and the lower inclined edge 157 are coplanar with the lower surface of the bottom plate 15 and the upper surface of the box, respectively, and are used to assist in the splicing and positioning of the side plate profile 10.

[0051] Since the lower hook portion 1222 of the second side plate 12 prevents the first side plate 11 from sliding downward, a lower inclined locking edge portion 157 extends from the inclined edge 153 of the bottom plate 15 near the locking protrusion 155 to block the upward movement of the first side plate 11, thus achieving bidirectional locking. Similarly, since the upper hook portion 1121 prevents the second side plate 12 from sliding upward, an upper inclined locking edge portion 156 extends from the inclined edge 153 of the bottom plate 15 near the notch 154 to block the downward sliding of the second side plate 12, thus achieving bidirectional locking.

[0052] Furthermore, the upper inclined edge portion 156 and the lower inclined edge portion 157 have the same length along the inclined side 153 of the base plate 15, and each occupies half the length of the inclined side 153 of the base plate 15, ensuring uniform force distribution during splicing.

[0053] In one embodiment, the upper inclined edge 156 is an upper inclined edge that protrudes from the inclined side 153 of the base plate 15 and is coplanar with the outer surface of the base plate 15. The outer surface of the upper inclined edge is higher than the outer surface of the inclined side 153 of the base plate 15, and an inner step (not shown in the figure) is formed on the outer surface of the upper inclined edge and the base plate 15. The thickness of the inner step on the outer surface of the base plate 15 is the same as that of the lower inclined edge.

[0054] Furthermore, the lower inclined edge 157 is a lower inclined edge that protrudes from the inclined side 153 of the base plate 15 and is coplanar with the inner surface of the base plate 15. The inner surface of the lower inclined edge is higher than the inner surface of the inclined side 153 of the base plate 15, and an outer step (not shown in the figure) is formed on the lower inclined edge and the inner surface of the base plate 15. The thickness of the outer step on the inner surface of the base plate 15 is the same as that of the upper inclined edge.

[0055] Specifically, when the two side panel profiles 10 are spliced, the inner step of one side panel profile 10 engages with the outer step of the other side panel profile 10, and the outer step of one side panel profile 10 engages with the inner step of the other side panel profile 10. Since the thickness of the inner step on the outer surface of the base plate 15 is the same as the thickness of the lower inclined clamping edge 157, and the thickness of the outer step on the inner surface of the base plate 15 is the same as the thickness of the upper inclined clamping edge 156, a tight engagement is achieved.

[0056] In one embodiment, see Figure 1 and Figure 2 The second aspect of this application provides a packaging box 200, which is assembled from packaging profiles 100. Specifically, two side panel profiles 10 are spliced ​​together by a snap-fit ​​structure to form a right quadrangular prism-shaped packaging box side panel 300, and the top cover 22 is fixed to the top of the side panel 300 by a snap-fit ​​structure to form a complete packaging box, which can be quickly assembled and disassembled, facilitating transportation and storage.

[0057] Compared with the prior art, the present invention has at least the following technical effects: 1. This utility model adopts an integrally formed side plate profile 10 and cover plate profile 20, and sets an interlocking structure on the two free sides of the two side plate profiles 10 respectively, so that the two side plate profiles 10 can be quickly spliced ​​to form a quadrangular prism-shaped packaging box side panel 300.
