Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging boxes, and particularly relates to a one-piece folding four-corner box. Background Art
[0002] Traditional four-corner packaging boxes mostly adopt a multi-piece structure and need to be assembled with adhesives such as glue and tape. This not only increases the production cost and complexity but also may cause the packaging box to disassemble due to the failure of the adhesive at high temperatures during transportation and use. In addition, the discarded adhesives and multi-layer structures also bring certain pressure to the environment. At the same time, for some small orders, the cost of separately opening molds for some four-corner packaging boxes is relatively high, and the production cycle is slow. Therefore, the utility model provides a one-piece folding four-corner box, which has a simple structure, is easy to manufacture by one-piece molding, does not require additional adhesives for fixation, and is a convenient-to-assemble packaging box.
[0003] Regarding the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model
[0004] To achieve the above object, the utility model provides the following technical solution: A one-piece folding four-corner box includes an integrally formed cardboard. The cardboard includes a bottom plate, the bottom plate has a rectangular structure, and side plates are connected to the four sides of the rectangular bottom plate. Inner folding plates are connected between adjacent side plates. One of the symmetrically arranged two side plates on one side of the bottom plate is respectively fixed with a cover plate and a pressing plate. One side of the cover plate is connected with a sealing strip plate, and the sealing strip plate, the cover plate, the bottom plate, the two symmetrically arranged side plates, and the pressing plate are collinear;
[0005] In addition, easy folding lines are provided on the surfaces of the other two symmetrically arranged side plates, the surfaces of the inner folding plates, both ends of the pressing plate, and the joints between the bottom plate, the side plates, the inner folding plates, the cover plate, the pressing plate, and the sealing strip plate. First cutting slits are symmetrically pressed on the easy folding line at the joint between the cover plate and the side plate, and pressing pieces are arranged inside the first cutting slits. Second cutting slits are pressed on the easy folding lines at both ends of the pressing plate, and first inserting pieces are arranged inside the second cutting slits. First inserting seams are pressed on the easy folding line on one side of one of the two inner folding plates close to the pressing plate, and the first inserting seams are adapted to the first inserting pieces.
[0006] As a preferred technical solution of the utility model, the ends of the easy folding lines on the surfaces of the side plates and the inner folding plates are connected.
[0007] As a preferred technical solution of the utility model, the two ends of the second cutting slit and the easy folding line at the end of the pressing plate are connected end to end.

Detailed Embodiments
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Embodiment
[0018] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: A one-piece foldable four-corner box includes an integrally formed cardboard, and the cardboard includes a bottom plate 1, and the bottom plate 1 exhibits a regular rectangular shape. At the four peripheral edges of the rectangular bottom plate 1, side plates 2 are connected, and inner folding plates 3 are connected between adjacent side plates 2 to achieve the function of folding into a box. On one side of two symmetrical side plates 2 on the bottom plate 1, a cover plate 4 and a pressing plate 5 are respectively connected. One side of the cover plate 4 is also provided with a sealing strip plate 6. These components together form a tight structure, and the sealing strip plate 6, the cover plate 4, the bottom plate 1, the two symmetrical side plates 2, and the pressing plate 5 are carefully arranged along the same straight line.
[0019] On the surfaces of the other two symmetrical side plates 2, the surfaces of the inner folding plates 3, both ends of the pressing plate 5, and all the connection parts between the bottom plate 1, the side plates 2, the inner folding plates 3, the cover plate 4, the pressing plate 5, and the sealing strip plate 6, easy folding lines 7 are cleverly provided for easy folding operation. At the connection between the cover plate 4 and the side plate 2, the first cutting seam 8 is pressed and cut symmetrically on the easy folding line 7. By breaking along the first cutting seam 8, a pressing piece 9 is formed inside the first cutting seam 8 for fixing the inner folding plate 3. At the same time, on the easy folding line 7 at both ends of the pressing plate 5, the second cutting seam 10 is also pressed and cut, and a first inserting piece 11 is provided inside it. Among the two inner folding plates 3 close to the pressing plate 5, on the easy folding line 7 on one side, a first inserting seam 12 matching the first inserting piece 11 is also pressed and cut to achieve a more firm inserting structure.
[0020] In order to ensure the coherence of the folding part, in this embodiment, as a preferred technical solution of the present utility model, the ends of the easy folding lines 7 on the surfaces of the side plates 2 and the inner folding plates 3 are connected.
[0021] In order to facilitate the exposure of the first inserting piece 11 directly after folding both ends of the pressing plate 5 along the easy folding line 7, in this embodiment, as a preferred technical solution of the present utility model, the two ends of the second cutting seam 10 and the easy folding line 7 at the end of the pressing plate 5 are connected end to end.
[0022] In summary, according to the technical solution provided by the present utility model, during the assembly process, the primary step is to apply pressure to the fold lines 7 at the joints of each board surface to prompt the corresponding board surfaces to fold. Subsequently, the inner folding board 3 is guided to fold along the established fold line 7 path on the surface to form a triangular shape and closely fit the two side boards 2 on both sides, thereby constituting a semi-closed box structure. In this box body, two of the triangular inner folding boards 3 closely adhere to the side board 2 connected to the cover board 4 and are firmly fixed thereto by means of the folding pressing piece 9. At the same time, the other two triangular inner folding boards 3 closely adhere to the side board 2 connected to the pressing plate 5. This process is completed by inverting the pressing plate 5 inward and inserting it into the interior of the box body, and ensuring that the first insertion pieces 11 at both ends of the pressing plate 5 can be smoothly inserted into the first insertion seams 12 on one side of the inner folding board 3 to achieve a firm plug-in fixation between the two. Finally, the cover board 4 is placed on the box body, and the second insertion piece 14 on one side of the seal strip board 6 is inserted into the second insertion seam 13.
[0023] Finally, it should be noted that in the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "rotation connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
