[0029] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

[0030] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" is not vertical in the strict sense, but within the allowable tolerance range. "Parallel" is not parallel in the strict sense, but within the allowable tolerance range.

[0031] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" 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 direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application depending on the specific circumstances.

[0033] Currently available flip-top magnetic plasterboard gift boxes not only require significant investment in materials such as boards, paper, and magnetic accessories, but also undergo complex processing steps including pasting, bonding, and accessory embedding. This results in low production efficiency, long production cycles, and high labor and manufacturing costs. Furthermore, these boxes cannot be laid flat and folded after shaping, leading to large storage and transportation space requirements, high logistics costs, and susceptibility to damage during transport. Additionally, the use of adhesives and irregularly shaped accessories results in a low overall recyclability rate. Newly emerging white cardboard gift boxes can partially replace magnetic plasterboard gift boxes, but they still rely on adhesive bonding, have poor flip-top locking structure stability, are prone to loosening, and have low overall rigidity. Their user experience and securing effect are far inferior to magnetic plasterboard gift boxes. The above statements are for informational purposes only and do not necessarily constitute prior art.

[0034] The flip-top packaging structure provided in this application includes a box body and two flip-tops. The box body includes a bottom wall and side walls. By folding the side walls and flip-tops, the flip-top packaging structure can be switched between an assembled state and a laid-out state. In the assembled state, the layered solid structure formed by folding the side walls and the bottom wall encloses the box structure to accommodate items. The box structure can be closed or opened by flipping the flip-tops. In the laid-out state, the bottom wall, the unfolded side walls, and the flip-tops are laid flat on the same plane to form a plate-like structure, which can effectively reduce the space occupied during storage and transportation, reduce logistics and storage costs, and reduce the possibility of damage during transportation. Moreover, the side walls form a layered solid structure by folding themselves, which, when combined with the bottom wall, constitutes a complete box body that can be directly used to accommodate items. The forming process does not require gluing, cutting, magnetic connection, or other processes, thus shortening the production cycle. Furthermore, the assembly operation is simple and convenient, with short assembly time for individual parts, and no special tools are required. In addition, after the product is formed, the side walls are folded to form a double-layer structure, which improves the overall rigidity and pressure resistance of the box, making the structure stable and enhancing the overall quality of the gift box.

[0035] To better understand this application, the following will be combined with... Figures 1 to 8 Describe it.

[0036] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a flip-top packaging structure in a formed state according to an embodiment of this application; Figure 2 This is a schematic diagram of a flip-top packaging structure in a flat state according to an embodiment of this application.

[0037] like Figure 1 and Figure 2 As shown, this application provides a flip-top packaging structure 100, which includes a box body 10 and two flip-tops 20.

[0038] The flip-top packaging structure 100 has a flat state and a formed state. In the flat state, the box body 10 and the two flip-tops 20 are located in the same plane and are generally plate-shaped. In the formed state, the box body 10 is used to accommodate the item to be placed.

[0039] In some examples, the flip-top packaging structure 100 is made of cardboard.

[0040] In some examples, the flip-top packaging structure 100 is a one-piece molded structure. It is formed into a single piece after die-cutting and creasing 30.

[0041] The box body 10 includes a bottom wall 11 and a side wall 12, with the side wall 12 arranged along the periphery of the bottom wall 11.

[0042] In some examples, an indentation 30 is provided between the bottom wall 11 and the side wall 12, and the side wall 12 can be bent relative to the bottom wall 11 along the indentation 30.

[0043] For example, the sidewall 12 may be bent 90° relative to the bottom wall 11 along the indentation 30.

[0044] The flip cover 20 is rotatably connected to the side wall 12, and the two flip covers 20 are arranged opposite each other along the first direction X.

[0045] Two flaps 20 are respectively connected to the two sides of the box body 10 so that they can be folded or unfolded separately, reducing mutual interference.

[0046] Optionally, the bottom wall 11, side wall 12, and flip cover 20 are integrally formed from the same material.

[0047] In some examples, the two flip covers 20 include a first flip cover and a second flip cover, which are rotatably connected to the side wall 12, and the first flip cover and the second flip cover are mirror symmetrical.

[0048] In the flat state, the side wall 12 and the flap 20 are both unfolded and laid flat on the same plane as the bottom wall 11.

[0049] In its flat state, the flip-top packaging structure 100 is generally plate-shaped, with a predetermined length, width, and thickness. The first direction X is parallel to the length direction, the second direction Y is parallel to the width direction, and the third direction Z is parallel to the thickness direction.

[0050] In the flat state, both the side wall 12 and the flap 20 are plate-shaped. The plate-shaped side wall 12 and flap 20 are laid flat on the same plane as the bottom wall 11, that is, the whole is plate-shaped, which occupies less space and is conducive to transportation and storage.

[0051] For example, when unfolded, in the first direction X, the bottom wall 11 and the side wall 12 are located between the two flaps 20, and the bottom wall 11, the side wall 12, and the flaps 20 do not overlap. After unfolding, the flapable packaging structure 100 has no overlap between the components and is laid flat as a whole. When stacked in storage, it is neatly arranged and tightly fitted, effectively improving the neatness of stacking and the utilization rate of storage space. At the same time, the stacking force is uniform, which can reduce structural deformation and damage under pressure, and also facilitates storage and bulk transfer operations.

[0052] In the formed state, the folding of the side wall 12 forms at least two layers of superimposed solid structure, which together with the bottom wall 11 form a box structure. The flap 20 is folded and flipped relative to the box structure to open or close the box structure.

[0053] The sidewall 12 is folded to form a layered solid structure of at least two layers. This can be understood as the sidewall 12 in the unfolded state being folded into a layered solid structure in the formed state, and the layered solid structure has at least two layers.

[0054] For example, the sidewall 12 is folded to form a layered solid structure, part of which has two layers and the other part has three layers.

[0055] For example, the sidewall 12 is folded to form a layered solid structure, which has three layers.

[0056] In some examples, in the formed state, the layered solid structure and the bottom wall 11 enclose a box structure, the box structure having an opening, the opening being positioned opposite the bottom wall 11 along the third direction Z. Two flaps 20 are flipped relative to the box structure, the two flaps 20 moving closer together to close the opening, and the two flaps 20 moving further apart to open the opening.

[0057] In some examples, in the formed state, the two flaps 20 approach each other and abut each other to close the opening.

[0058] The flip-top packaging structure 100 provided in this application includes a box body 10 and two flip-tops 20. The box body 10 includes a bottom wall 11 and side walls 12. By folding the side walls 12 and the flip-tops 20, the flip-top packaging structure 100 can be switched between a lined state and a flat state. In the lined state, the layered solid structure formed by folding the side walls 12 and the bottom wall 11 encloses the box structure to accommodate items, and the box structure can be closed or opened by flipping the flip-tops 20. In the flat state, the bottom wall 11, the unfolded side walls 12, and the flip-tops 20 are laid flat on the same plane to form a plate-like structure, which can effectively reduce the space occupied during storage and transportation, reduce logistics and storage costs, and reduce the possibility of damage during transportation.

[0059] Furthermore, the side walls 12 form a layered, solid structure through their own folding, which, when combined with the bottom wall 11, constitutes the complete box 10, ready to hold items. The molding process eliminates the need for gluing, cutting, or magnetic connections, reducing the production cycle. Assembly is simple and convenient, with short assembly times for individual pieces and no need for specialized tools. Moreover, after molding, the side walls 12 fold to form a double-layered structure, enhancing the overall rigidity and pressure resistance of the box 10, resulting in a stable structure and improved overall quality.

[0060] See also Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of a portion of a flip-top packaging structure according to an embodiment of this application in a flat state; Figure 4 This is a schematic diagram of a portion of a flip-top packaging structure in a flat state, according to another embodiment of this application.

[0061] The flip-top packaging structure 100 as described above, such as Figures 2 to 4 As shown, the sidewall 12 includes a first connecting portion 121, a second connecting portion 122, and a first locking portion 123. The first connecting portion 121 and the second connecting portion 122 are arranged around the bottom wall 11 and are respectively connected to the bottom wall 11. The second connecting portion 122 is connected to the first locking portion 123 and the flip cover 20. In the flat state, the first connecting portion 121, the second connecting portion 122, and the first locking portion 123 do not overlap. In the formed state, the first connecting portion 121 is bent relative to the bottom wall 11 and folded back towards the bottom wall 11 to form a two-fold structure. The second connecting portion 122 is bent relative to the bottom wall 11 and folded to the side away from the bottom wall 11. The first locking portion 123 extends from the edge of the second connecting portion 122 and bends towards the first connecting portion 121, and the first locking portion 123 is clamped and fixed between the two-fold structure.

[0062] The sidewall 12 includes a first connecting part 121, a second connecting part 122 and a first locking part 123. The three parts can be bent independently to form a layered solid structure.

[0063] In some examples, indentations 30 are provided between the first connecting part 121 and the bottom wall 11, between the second connecting part 122 and the bottom wall 11, and between the first locking part 123 and the second connecting part 122.

[0064] For example, the first connecting portion 121 may be bent relative to the bottom wall 11 along the indentation 30 between the first connecting portion 121 and the bottom wall 11. For example, the first connecting portion 121 may be bent 90° relative to the bottom wall 11 along the indentation 30.

[0065] In some examples, the first connecting portion 121 is provided with an indentation 30 for folding back the first connecting portion 121.

[0066] For example, the first connecting portion 121 can be folded back along the indentation 30 to form a two-fold structure. For instance, the first connecting portion 121 can be folded back 180° along the indentation 30.

[0067] In some examples, the second connecting portion 122 may be bent relative to the bottom wall 11 along the indentation 30 between the second connecting portion 122 and the bottom wall 11. For example, the second connecting portion 122 may be bent 90° relative to the bottom wall 11 along the indentation 30, and the first connecting portion 121 and the second connecting portion 122 form a 90° angle.

[0068] In some examples, the second connecting portion 122 is provided with an indentation 30 for folding the second connecting portion 122.

[0069] For example, the second connecting portion 122 can be folded along the indentation 30 on the second connecting portion 122 to the side opposite to the bottom wall 11. For example, the first connecting portion 121 can be folded 180° along the indentation 30.

[0070] Optionally, in the laid-out state, an indentation 30 is provided on the center line of the second connecting part 122.

[0071] In some examples, the first locking portion 123 is disposed on the edge of the second connecting portion 122 near the edge of the first connecting portion 121, and the first locking portion 123 is connected to a portion of the edge, or the first locking portion 123 is connected to the entire edge. In the molded state, at least a portion of the first locking portion 123 is connected to the portion of the edge located on the side opposite to the bottom wall 11.

[0072] For example, in the molded state, the edge includes a first edge and a second edge connected together, the second edge being located on the side of the first edge away from the bottom wall 11, and at least a portion of the first locking part 123 is connected to the second edge. This arrangement is to connect and fix the first connecting part 121 and the second connecting part 122, thereby improving the overall structural strength and connection stability of the box structure.

[0073] In some examples, the first locking portion 123 may be bent toward the bottom wall 11 along the indentation 30 between the first locking portion 123 and the second connecting portion 122. For example, the first connecting portion 121 may be bent 90° along the indentation 30.

[0074] In this embodiment, the first connecting part 121 is folded back and the second connecting part 122 is folded over to form a two-fold structure, which effectively improves the overall rigidity and compressive strength of the box structure, and at the same time facilitates the flexible switching of the box 10 between the flat unfolded state and the molded use state.

[0075] The flip-top packaging structure 100 as described above, such as Figures 2 to 4As shown, the side wall 12 includes two first connecting parts 121 and two second connecting parts 122. The two first connecting parts 121 are disposed on both sides of the bottom wall 11 along the first direction X, and the two second connecting parts 122 are disposed on both sides of the bottom wall 11 along the second direction Y. The first connecting parts 121 are connected to the flip cover 20. The first connecting parts 121 are provided with a first locking part 123 on both sides along the second direction Y. The first direction X is perpendicular to the second direction Y.

[0076] For example, the bottom wall 11 is generally rectangular in shape, with two long sides and two short sides, two first connecting parts 121 are respectively connected to the two short sides, and two second connecting parts 122 are respectively connected to the two long sides.

[0077] In some examples, in the molded state, along the first direction X, the size of the first locking portion 123 is greater than or equal to half the size of the first connecting portion 121. This arrangement results in a larger connection area between the first locking portion 123 and the first connecting portion 121, and increases their overlap area, thereby improving connection stability and compressive strength.

[0078] See also Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of a portion of the flip-top packaging structure of another embodiment of this application in a flat state; Figure 6 This is a schematic diagram of a flip-top packaging structure in a formed state according to an embodiment of this application, with the flip-top open.

[0079] The flip-top packaging structure 100 as described above, such as Figure 2 , Figures 4 to 6 As shown, the second connecting portion 122 includes a first segment 1221 and a second segment 1222. The first segment 1221 is located between and connects the second segment 1222 and the bottom wall 11. The second segment 1222 is connected to the flap 20, and the first locking portion 123 is connected to the first segment 1221 and the second segment 1222. In the molded state, the first segment 1221 is bent relative to the bottom wall 11, the second segment 1222 is connected to the edge of the first segment 1221 away from the bottom wall 11 and folded to the side of the first segment 1221 opposite to the bottom wall 11, and the flap 20 is connected to the edge of the second segment 1222 near the bottom wall 11.

[0080] For example, the first segment 1221 is first bent relative to the bottom wall 11, then the second segment 1222 is folded to the side of the first segment 1221 away from the bottom wall 11, and then the first locking part 123 is bent toward the first connecting part 121.

[0081] In some examples, the first segment 1221 may be bent relative to the bottom wall 11 along the indentation 30 between the first segment 1221 and the bottom wall 11. For example, the first segment 1221 may be bent 90° relative to the bottom wall 11 along the indentation 30.

[0082] In some examples, the second segment 1222 can be folded along the indentation 30 between the first segment 1221 and the second segment 1222 and folded to the side of the first segment 1221 away from the bottom wall 11 to form a two-fold structure. For example, the second segment 1222 can be folded 180° along the indentation 30. After folding, the second segment 1222 can be stacked with the first segment 1221.

[0083] In some examples, the area of ​​the first segment 1221 is equal to the area of ​​the second segment 1222. The second connecting part 122 is folded along the centerline to form a double-layer structure, which has a consistent thickness after molding, good structural symmetry, and simplifies the assembly method.

[0084] In some examples, the first segment 1221 is provided with a first locking part 123 on both sides along the second direction Y, and the second segment 1222 is provided with a first locking part 123 on both sides along the second direction Y.

[0085] Optionally, in the flat state, the area of ​​the first locking part 123 provided in the first segment 1221 is equal to the area of ​​the first locking part 123 provided in the second segment 1222.

[0086] In this embodiment, the flip cover 20 is connected to one end of the side wall 12 of the second section 1222 near the bottom wall 11. When in the formed state, it can partially wrap the side wall 12, effectively strengthening the overall frame structure of the box body 10. At the same time, after the two flip covers 20 are closed, they fit tightly against the side wall 12, forming mutual restraint to keep the flip covers 20 in the closed state, and can also be opened and closed repeatedly.

[0087] The flip-top packaging structure 100 as described above, such as Figure 2 , Figures 4 to 6 As shown, the first connecting portion 121 includes a third segment 1211 and a fourth segment 1212. The third segment 1211 is connected to the bottom wall 11, and the fourth segment 1212 is connected to the third segment 1211. In the formed state, the third segment 1211 is bent relative to the bottom wall 11, and the fourth segment 1212 is connected to the edge of the first segment 1221 away from the bottom wall 11 and folded back. The first locking portion 123 clamps and fixes between the third segment 1211 and the fourth segment 1212.

[0088] For example, the first segment 1221 is first bent relative to the bottom wall 11, then the second segment 1222 is folded to the side of the first segment 1221 away from the bottom wall 11, and then the first locking part 123 is bent toward the first connecting part 121; the third segment 1211 is first bent relative to the bottom wall 11, then the fourth segment 1212 is folded back and the first locking part 123 is clamped between the third segment 1211 and the fourth segment 1212 for fixation.

[0089] In some examples, the third segment 1211 may be bent relative to the bottom wall 11 along the indentation 30 between the third segment 1211 and the bottom wall 11. For example, the third segment 1211 may be bent 90° relative to the bottom wall 11 along the indentation 30.

[0090] In some examples, the fourth segment 1212 can be folded back along the indentation 30 between the third segment 1211 and the fourth segment 1212 to form a two-fold structure. For example, the fourth segment 1212 can be folded back 180° along the indentation 30. After folding back, the fourth segment 1212 can be stacked with the third segment 1211.

[0091] In this embodiment, the first connecting part 121 folds back and locks into the first locking part 123, thus connecting the first connecting part 121, the second connecting part 122, and the first locking part 123 into a single unit, making the side wall 12 a one-piece three-dimensional structure in its formed state. The interconnected parts are locked together to form a whole, effectively improving the integrity and structural strength of the side wall 12, making it less prone to loosening and deformation. No additional adhesive or nailing parts are needed to fold the box body 10 into a single piece, simplifying the process and reducing production costs.

[0093] The flip-top packaging structure 100 as described above, such as Figure 7 and Figure 9 As shown, the flip cover 20 also includes a plug-in portion 13, which protrudes from the first connecting portion 121. The bottom wall 11 is provided with a slot 111 for engaging with the plug-in portion 13. In the formed state, the plug-in portion 13 is located at one end of the fourth segment 1212 near the bottom wall 11 and is plugged into the slot 111.

[0094] In some examples, the bottom wall 11 is provided with a slot 111, and the flip cover 20 also includes a plug-in part 13. The plug-in part 13 protrudes from the fourth segment 1212. In the molded state, the plug-in part 13 is located at the end of the second segment 1222 near the bottom wall 11 and plugs into the slot 111. This arrangement can limit and fix the side wall 12 and the bottom wall 11 after molding, stabilizing the overall shape. At the same time, the plug-in structure is easy to assemble and disassemble, which facilitates the flexible switching between the two states of the box body 10: flat unfolding and molded use.

[0095] The flip-top packaging structure 100 as described above, such as Figure 2 , Figure 3 and Figure 7 As shown, the flip cover 20 includes a first cover 21, a second cover 22, and a third cover 23. The first cover 21 is rotatably connected to the side wall 12, and the second cover 22 is connected to the first cover 21 and the third cover 23. In the flat state, the second cover 22 is located between the first cover 21 and the third cover 23. In the formed state, the second cover 22 is bent relative to the first cover 21 and folded back towards the first cover 21 to form a two-fold structure. The third cover 23 is connected to the edge of the second cover 22 near the first cover 21 and is stacked on top of the first cover 21. The second cover 22 is used to close the box structure.

[0096] For example, in the formed state, the flap 20 may be in the shape of an inverted L.

[0097] In some examples, the first cover 21 is flip-connected to the edge of the second segment 1222 of the sidewall 12 near the bottom wall 11.

[0098] In some examples, in the formed state, the second cover 22 of the two flip covers 20 are positioned opposite each other.

[0099] In some examples, indentations 30 are provided between the first cover 21 and the side wall 12, between the first cover 21 and the second cover 22, and between the second cover 22 and the third cover 23.

[0100] For example, the second cover 22 may be bent relative to the first cover 21 along the indentation 30 between the second cover 22 and the first cover 21. For instance, the second cover 22 may be bent 90° relative to the first cover 21 along the indentation 30.

[0101] In some examples, the second cover 22 is provided with an indentation 30 for folding back the second cover 22.

[0102] For example, the second cover 22 can be folded back along the indentation 30 on the second cover 22 to form a two-fold structure. For example, the second cover 22 can be folded back 180° along the indentation 30.

[0103] In some examples, the third cover 23 may be bent relative to the second cover 22 along the indentation 30 between the third cover 23 and the second cover 22 and stacked with the first cover 21. For example, the second cover 22 may be bent 90° relative to the first cover 21 along the indentation 30.

[0104] In this embodiment, the third cover 23 is connected to the second cover 22 and overlaps with the first cover 21, which can effectively limit the second cover 22 and maintain the shaping effect of the second cover 22 after folding. Moreover, the overlapping parts abut against each other and are subjected to force, which effectively improves the overall support strength and deformation resistance of the flip cover 20.

[0105] The flip-top packaging structure 100 as described above, such as Figure 3 and Figure 7 As shown, the flip cover 20 also includes a side portion 24 and a second locking portion 25. The side portion 24 is connected to the first cover body 21, and the second locking portion 25 is connected to the first cover body 21. In the flat state, the second locking portion 25 is located on the side of the side portion 24 away from the side wall 12. In the formed state, the side portion 24 is bent relative to the first cover body 21, and the second locking portion 25 is bent relative to the side portion 24 and clamped and fixed between the two fold structures.

[0106] In some examples, the side portion 24 may be bent relative to the first cover 21 along the indentation 30 between the side portion 24 and the first cover 21. For example, the side portion 24 may be bent 90° relative to the first cover 21 along the indentation 30.

[0107] In some examples, the second locking portion 25 may be bent relative to the side portion 24 along the indentation 30 between the side portion 24 and the second locking portion 25, and clamped and fixed between the two fold structures. For example, the second locking portion 25 may be bent relative to the side portion 24 along the indentation 30.

[0108] In some examples, the second locking part 25 is first bent relative to the side part 24, then the side part 24 is bent relative to the first cover 21, and then the second cover 22 is bent relative to the first cover 21 and folded back towards the first cover 21 to form a two-fold structure, with the second locking part 25 fixed between the two-fold structure.

[0109] In other examples, the side portion 24 is first bent relative to the first cover 21, then the second locking portion 25 is bent relative to the side portion 24, and then the second cover 22 is bent relative to the first cover 21 and folded back towards the first cover 21 to form a two-fold structure, with the second locking portion 25 fixed between the two-fold structure.

[0110] In some examples, the first cover 21 has a side portion 24 and a second locking portion 25 on both sides along the first direction X.

[0111] In this embodiment, the side portion 24 is used to fit and limit the fit, thereby improving the tightness of the fit between the flip cover 20 and the box body 10 and enhancing the overall sealing performance. In addition, the side portion 24 provides lateral constraint to the box body 10, effectively reinforcing the box structure and improving the overall molding stability.

[0112] The flip-top packaging structure 100 as described above, such as Figure 2 , Figure 3 and Figure 7 As shown, the second cover 22 includes a first sub-part 221 and a second sub-part 222. The first sub-part 221 is connected to the first cover 21, and the second sub-part 222 is connected to the first cover 21 and the third cover 23. In the molded state, the first sub-part 221 is bent relative to the first cover 21, and the second sub-part 222 is connected to the edge of the first sub-part 221 away from the first cover 21 and folded back towards the first cover 21. The second locking part 25 is clamped and fixed between the first sub-part 221 and the second sub-part 222.

[0113] In some examples, the second sub-part 222 can be folded back along the indentation 30 between the first sub-part 221 and the second sub-part 222 to form a two-fold structure. For example, the second sub-part 222 can be folded back 180° along the indentation 30.

[0114] For example, the tongue 26 is disposed on the second sub-part 222.

[0115] The flip-top packaging structure 100 as described above, such as Figure 7 and Figure 8 As shown, the flip cover 20 also includes a tongue 26, which is located at one end of the second cover 22 near the third cover 23 and protrudes from the second cover 22. The third cover 23 has a recess 231, and the first cover 21 has an insertion hole 211 for engaging with the tongue 26. In the flat state, the tongue 26 is received within the recess 231. In the molded state, the tongue 26 is inserted into the insertion hole 211.

[0116] For example, the second cover 22 is provided with two spaced-apart tongues 26, and the first cover 21 is provided with two holes 211 corresponding to the two tongues 26. The two sets of tongues 26 and holes 211 cooperate to lock together, resulting in a better shaping effect.

[0117] In this embodiment, the tongue 26 and the hole 211 are inserted and engaged to limit and fix the flip cover 20, stabilize the shape of the flip cover 20, and the plug-in structure is easy to disassemble and assemble, which facilitates the switching between the two states of the flip cover 20 being laid flat and in use.

[0118] The flip-top packaging structure 100 described above has a weight of less than or equal to 400g.

[0119] In some examples, the weight of the flip-top packaging structure 100 is less than or equal to 350g.

[0120] The flip-top packaging structure 100 described above uses white cardboard.

[0121] The flip-top packaging structure 100 is made of white cardboard, eliminating the need for magnetic closures, adhesives, and other auxiliary materials. Furthermore, its raw material cost is only 15%-20% of that of grey board. The production process of the flip-top packaging structure 100 can be simplified to just two core steps: die-cutting and creasing, reducing overall processing steps and labor costs by over 60%. In addition, the flip-top packaging structure 100 is integrally molded, allowing for full-page printing, hot stamping, UV coating, and other processes without the need for subsequent paper mounting, resulting in better consistency between the printed and finished products.
