Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a double-door box. Background Technology

[0002] In the packaging industry, double-door boxes are widely used for packaging gifts, food, and daily necessities due to their convenient opening and closing and good display features. However, existing double-door boxes still have many technical defects that need to be improved in actual use, making it difficult to meet users' higher demands for packaging functionality, stability, and practicality.

[0003] In terms of box structure design, the closure stability of existing double-door boxes is generally poor. Most products rely solely on the overlap of the cover to achieve closure, lacking an effective fixing structure. When subjected to vibration or tilting, the cover is prone to opening on its own, causing internal items to be exposed or fall out. Although some double-door boxes have simple buckle structures, the connection strength of the buckles is low, and they are prone to wear and failure after long-term use, making it difficult to guarantee the long-term reliability of the box closure.

[0004] Furthermore, existing double-door boxes have relatively limited internal space utilization and functionality. Traditional double-door boxes are mostly single-cavity structures, which cannot classify and store internal items. When multiple items need to be packaged at the same time, different items are prone to collision and mixing, affecting the integrity and display effect of the items.

[0005] Therefore, a double-door box needs to be designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a double-door box. This utility model has the advantages of reasonable structural design, excellent material performance, stable and reliable closure, flexible internal functions, and convenient assembly and use. It comprehensively solves various technical shortcomings of existing double-door boxes in practical applications and meets users' higher demands for packaging functionality, stability, and practicality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A double-door box includes an integrally formed box body, two cover plates, four side plates, and two inner plates. The two cover plates are symmetrically arranged, and one side of each cover plate is rotatably connected to the upper edge of the box body through a first fold to realize the opening and closing action of the double doors. The four side plates are divided into two groups, and one side of each of the two side plates in each group is rotatably connected to the upper and lower edges of one cover plate through a second fold to cooperate with the side wall of the box body to form a circumferential enclosure of the box body when the cover plate is closed. One side of each of the two inner plates is rotatably connected to the adjacent side of the two cover plates through a third fold.

[0009] Preferably, the box body, cover, side panels, and inner panel are all formed from corrugated cardboard.

[0010] Preferably, the inner top and inner bottom of the box are provided with sliding grooves, and a partition is slidably connected in both sliding grooves. An insertion groove is provided on the front side of the partition.

[0011] Preferably, the height of the partition and the inner panel is the same as the internal width of the box.

[0012] Preferably, the cover plate has symmetrical openings on the upper and lower sides, and a fixing block is fixedly connected to the inner wall of each pair of matching openings. A rubber band is fixedly connected to each fixing block, and a fixing button is fixedly connected to the upper front side of the box.

[0013] Preferably, the width of the insertion slot is the same as the sum of the thicknesses of the two inner plates.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with existing technologies, this device uses corrugated cardboard to form the box body, cover, side panels and inner panels in one piece. The multi-layer structure of corrugated cardboard can significantly improve the overall structural strength of the box body, effectively resist external pressure during transportation or storage, and at the same time have better moisture resistance to avoid softening due to moisture. Moreover, the cost of corrugated cardboard is lower than that of high-strength plastics. While ensuring performance improvement, it does not increase costs too much, thus balancing practicality and economy.

[0016] 2. Compared with the existing technology, this device adopts a double closing and fixing mechanism of "inner plate cooperation + rubber band - fixing button". The inner plates overlap each other when the cover is closed, which initially improves stability. The cooperation of the rubber band and the fixing button further strengthens the cover and prevents accidental opening. At the same time, this fixing structure has no easily worn buckle parts, has a longer service life, and can ensure the reliability of the box closure for a long time.

[0017] 3. Compared with existing technologies, this device features a sliding partition design, allowing users to flexibly adjust the partition position according to the quantity and type of items. This enables the storage of multiple types of items or the storage of a single item, improving space utilization. At the same time, the design of the insertion slot matching the thickness of the inner plate ensures precise fit between the partition and the inner plate, preventing jamming or loosening during opening and closing, ensuring smooth operation and greatly optimizing the user experience.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A double-door box includes an integrally formed box body 1, two cover plates 2, four side plates 4, and two inner plates 3. The box body 1, cover plates 2, side plates 4, and inner plates 3 are all formed from corrugated cardboard. The multi-layer corrugated structure of the corrugated cardboard can improve the bending strength and cushioning performance of each component, and avoid deformation of the components due to external pressure during transportation or use. At the same time, corrugated cardboard has good environmental protection properties, can be recycled and reused, and meets the requirements of green packaging.

[0024] Two cover plates 2 are symmetrically arranged, and one side of each cover plate is rotatably connected to the upper edge of the box body 1 through the first fold, so as to realize the opening and closing action of the double door. The depth of the first fold is adapted to the thickness of the corrugated cardboard, ensuring that the fold is not easy to break when the cover plate 2 rotates. The rotation angle of the two cover plates 2 can reach 180°. When fully opened, they can fit against the two outer walls of the box body 1 without obstructing the interior of the box body 1, making it convenient to take out and put in items from the inside of the box body 1.

[0025] The four side panels 4 are divided into two groups. One side of each of the two side panels 4 is rotatably connected to the upper and lower edges of a cover plate 2 through the second crease. This is used to cooperate with the side wall of the box body 1 to form a circumferential enclosure of the box body 1 when the cover plate 2 is closed. The direction of the second crease is parallel to the edge of the cover plate 2.

[0026] One side of each of the two inner panels 3 is rotatably connected to the adjacent side of the two cover plates 2 through the third fold. The length of the third fold is the same as the length of the side of the inner panel 3. The inner panel 3 can rotate into the box 1 along the third fold. When the cover plate 2 is closed, the two inner panels 3 can approach each other and form an overlapping state, filling the gap between the two cover plates 2 and preventing dust or small particles of impurities from entering the box 1.

[0027] The box body 1 has a sliding groove 10 at its inner top and inner bottom. A partition 9 is slidably connected in both sliding grooves 10. An insertion groove 11 is provided on the front side of the partition 9. The height of the partition 9 and the inner plate 3 is the same as the internal width of the box body 1. This height design allows the partition 9 to completely separate the internal space of the box body 1. When the inner plate 3 is closed, it can fit against the side of the partition 9, further restricting the position of the partition 9. The width of the insertion groove 11 is the same as the sum of the thicknesses of the two inner plates 3.

[0028] The cover plate 2 has symmetrical openings 7 on its upper and lower sides. Each pair of matching openings 7 has a fixing block 8 fixedly connected to the inner wall of the adjacent side. The fixing block 8 is made of the same corrugated cardboard material as the cover plate 2 and is fixed to the inner wall of the opening 7 by adhesive. Its surface is flat and can stably connect the rubber band 6. Each fixing block 8 has a rubber band 6 fixedly connected to it. The length of the rubber band 6 is adapted so that when the cover plate 2 is closed, the rubber band 6 can be stretched to the fixing button 5 on the front side of the box body 1. After stretching, it has enough elastic tension to firmly fix the cover plate 2. The upper front side of the box body 1 is fixedly connected to a fixing button 5. The fixing button 5 is a circular protrusion structure with a diameter slightly larger than the inner diameter of the rubber band 6 to ensure that the rubber band 6 is not easy to fall off after being put on the fixing button 5.

[0029] The functional principle of this utility model can be explained through the following operation: Since the box body 1, two cover plates 2, four side plates 4, and two inner plates 3 are integrally formed, assembly only requires rotation along the fold lines: First, rotate the two cover plates 2 along the first fold line towards the upper edge of the box body 1, so that the cover plates 2 are in an initial openable state; then divide the four side plates 4 into two groups, and rotate them along the second fold line towards the upper and lower edges of the corresponding cover plates 2, so that the side plates 4 form a perpendicular angle with the cover plates 2. At this time, the side plates 4 have the basis for subsequent cooperation with the side wall of the box body 1 to form a circumferential enclosure; finally, rotate the two inner plates 3 along the third fold line towards the adjacent side of the cover plate 2, so that the inner plates 3 are perpendicular to the cover plates 2, preparing for improved stability when closed. The entire assembly process does not require additional tools or adhesives and is easy to operate.

[0030] After assembly, the internal space of the box 1 can be adjusted according to the needs of the stored items. When a single item needs to be placed, the partition 9 can be removed. When two items or different types of items need to be placed, the partition 9 is aligned with the sliding grooves 10 at the top and bottom of the box 1. The partition 9 is pushed along the sliding grooves 10 to divide different areas and meet the needs of classified storage. At the same time, the width of the insertion slot 11 on the front side of the partition 9 is the same as the sum of the thicknesses of the two inner panels 3. When the partition 9 is adjusted to the appropriate position, the insertion slot 11 can precisely cooperate with the subsequently closed inner panels 3 to prevent the partition 9 from shifting or getting stuck during use and to ensure the stability of the space after adjustment.

[0031] In daily use, the opening, closing, and fixing operations are achieved through the coordinated action of the cover plate 2, inner plate 3, rubber band 6, and fixing button 5: To open, first remove the rubber band 6 connected to the fixing block 8 on the cover plate 2 from the fixing button 5 on the front side of the box body 1, then pull the cover plate 2 to both sides. The cover plate 2 can be opened by rotating along the first fold line. At this time, the side plate 4 unfolds synchronously with the rotation of the cover plate 2, and the inner plate 3 also disengages from the engagement state with the movement of the cover plate 2, making it convenient to take out and put in items; to close, first rotate the two side covers 2 along the first fold line towards the middle of the box body 1, which will drive the side plates 4 Simultaneously, the side panel 4 moves closer to the side wall of the box body 1 until it fits against the side wall of the box body 1 to form a circumferential barrier. At the same time, the two inner panels 3 overlap each other as the cover 2 closes, initially enhancing the closing stability of the cover 2. Finally, the rubber band 6 on the cover 2 is stretched and put on the fixing button 5 on the front of the box body 1. The elastic tension of the rubber band 6 further fixes the cover 2, preventing the cover 2 from opening on its own due to vibration or tilting of the box body 1, ensuring the reliability after closing. The entire opening, closing and fixing process is smooth and continuous, and all components fit tightly, enabling it to function stably for a long time.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
