[0002] Fruit logistics packaging boxes are widely used in fruit transportation and are used in huge quantities. Currently, the fruit logistics packaging boxes on the market are usually cardboard boxes, foam boxes, board boxes or plastic box structures.

[0003] Among them, most cartons are formed by embossing, cutting, and then stapling or gluing together. The demand for paper is large, and the overall structural strength is average, which is not convenient for reuse. In addition, it is easy to be damaged by moisture, and most of them are disposable packaging with a short service life. It is not suitable for scenarios that require long-distance transportation. At the same time, since paper packaging boxes require a small amount of metal connectors and a large amount of adhesives and tapes during the manufacturing and use process, it is not conducive to the production, processing, and recycling of packaging boxes, which increases the production and recycling costs of packaging boxes.

[0004] In addition, although the one-piece foldable hollow board PP box does not use the above materials, it has a high folding frequency and cumbersome operation.

[0005] The structure of plastic packaging boxes is integrally formed, with high structural strength and strong ability to be reused, but most of them cannot be disassembled, making them inconvenient to use.

[0006] Wooden packaging boxes have high structural strength and are highly reusable, but they are heavy, inconvenient to transport and store empty boxes, and are costly.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0056] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0057] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0058] like Figure 1-Figure 6As shown, the packaging box comprises: a bottom plate 1 and a side plate 2, the bottom plate 1 and the side plate 2 are integrally formed, and the adjacent side plates 2 are detachably connected by locking members 3. The connection strength between the side plates 2 and the bottom plate 1 is ensured, and the position of the side plates 2 relative to the bottom plate 1 is further fixed by the locking members 3. The overall structural design is simple, and the side plates 2 can stand up relative to the bottom plate 1, and the structure of the box body is formed by the side plates 2 and the bottom plate 1, which can meet the storage requirements of the storage items.

[0059] In order to realize the fixing effect of the locking member 3 on the side panel 2, the locking member 3 can also mainly support the side panel 2, especially when stacked up and down, it can support the box body stacked on the upper side to avoid the side panel 2 from being insufficiently loaded, or to meet the sufficient load-bearing, causing the side panel 2 to be bent or affecting the service life of the side panel. The locking member 3 includes: a first locking card slot 31 for limiting and fixing the side panel 2 on one side, a second locking card slot 32 for limiting and fixing the adjacent side panel 2, and a bearing column 33 for supporting. The first locking card slot 31 and the second locking card slot 32 are fixedly connected or integrally formed by the bearing column 33, and the fixing effect of the first locking card slot 31 and the second locking card slot 32 is realized. The first locking card slot 31 and the second locking card slot 32 are respectively inserted into the side parts of the adjacent side panels 2; thereby further meeting the limiting effect on the adjacent side panels 2, so that the side panels 2 can be ensured to stand up relative to the bottom plate to enclose the storage space of the packaging box.

[0060] In order to ensure the load-bearing function of the load-bearing column 33 and avoid the load-bearing weight from pressing on the side panel, the height of the load-bearing column 33 is the same as the height of the side panel 2 or the height of the load-bearing column 33 is greater than the height of the side panel 2. It is ensured that during the load-bearing process, all the weight will be borne on the load-bearing column 33. In order to ensure flatness, the height of the load-bearing column 33 is preferably the same as the height of the side panel 2.

[0061] In order to increase the load-bearing area of ​​the load-bearing column 33, thereby improving the load-bearing effect of the load-bearing column 33, the locking member 3 also includes: a load-bearing plate 34 whose size is larger than the end area of ​​the load-bearing column 33, and the first locking slot 31, the second locking slot 32 and the upper end of the load-bearing column 33 are integrally formed or fixedly connected to the load-bearing plate 34.

[0062] In order to ensure that the load-bearing plate 34 can be flush with the upper end of the side plate 2 and to ensure that no idle cavity is left in the height direction of the product, a mounting opening 21 is provided at the upper side of the adjacent side plate 2, and the height of the mounting opening 21 is the same as the thickness of the load-bearing plate 34, and the load-bearing plate 34 is arranged inside the mounting opening 21. The upper surface of the load-bearing plate 34 is ensured to be flush with the upper end of the side plate 2, the structural design is compact, no space is wasted, and during the stacking process, the total height can be reduced, the degree of fit is improved, and stability is ensured.

[0063] In order to connect the upper and lower adjacent packaging boxes during the stacking process, a stopper 4 is protruding from the middle of the load-bearing plate 34, and a stopper hole 5 is provided below the load-bearing plate 34 through the bottom plate 1, and the line between the stopper hole 5 and the stopper 4 is perpendicular to the bottom plate 1. The diameters of adjacent packaging boxes are mutually limited by the stopper 4 extending into the stopper hole 5, thereby improving the stability between adjacent packaging boxes.

[0064] In order to improve the limiting effect of the limiting member 4, the limiting member 4 includes: a limiting head 41 and a limiting column 42. The limiting head 41 is spherical, and the diameter of the limiting head 41 is larger than the limiting column 42. The diameter of the limiting hole 5 is the same as the diameter of the limiting head 41. Since the limiting head 41 has a larger diameter, the limiting head 41 can be selected to extend out of the limiting hole 5, so that the limiting head 41 can be limited and not easy to slide out of the limiting hole 5. Of course, the limiting head 41 may not extend out of the limiting hole 5, and a certain gap is left between the limiting column 42 and the limiting hole 5 to facilitate the separation of the packaging boxes and avoid mutual jamming.

[0068] In a preferred embodiment, the number of the side panels 2 is 7; and the packaging box is a heptagonal prism structure.

[0069] In a preferred embodiment, the number of the side panels 2 is 8; and the packaging box is an octagonal prism structure.

[0070] In a preferred embodiment, the number of the side panels 2 is 4; the bottom panel 1 is a rectangular structure, and the length-to-width ratio of the bottom panel 1 is 2:1;

[0071] An internal hole 6 is provided along the middle of the long side of the rectangle, and the distance between the two limiting holes 5 in the width direction of the rectangle is the same as the distance between the limiting hole 5 and the internal hole 6. The upper and lower adjacent layers of packaging boxes can be stacked in a transverse and longitudinal staggered manner, so that the internal hole of the upper layer of packaging boxes can extend into the limiting member 4, and the transverse and longitudinal staggered arrangement is connected to each other to ensure the stability of the stacking.

[0072] In order to meet the requirement that two packing boxes can be arranged longitudinally on the upper side of a packing box, and the two packing boxes on the upper side are limited respectively, four internal holes 6 are provided. Thus, the internal holes 6 and the limiting holes 5 meet the requirement that the limiting member 4 on the lower side extends into the limiting position.

[0073] In order to meet the requirements of staggered stacking of the upper and lower stacked packaging boxes at different positions and meet the needs of different stacking requirements, a side adjustment hole 7 is provided between the two limit holes 5 in the width direction of the bottom plate 1;

[0074] The connecting line of the two internal holes 6 is parallel to the width direction of the bottom plate 1, and an internal adjustment hole 8 is opened between the two internal holes 6;

[0075] The connecting line of the inner adjustment hole 8 and the side adjustment hole 7 is perpendicular to the width direction of the bottom plate 1 .

[0076] Therefore, the inner adjustment hole 8 and the side adjustment hole 7 facilitate the insertion of the two limiting members 4 at the lower side, thereby satisfying the limiting function at different positions.
